Protective Factors for Adolescents from Dysfunctional Family Dynamics Essay

The family is the major social unit for emotional development in adolescents. The family is an integral social system, held together by strong bonds of affection and caring; at the same time, family members exercise control, approval, and dissent for each other’s actions (Husain & Catwell 1992). As part of this interaction, every family has a structure, whether dysfunctional or functional, chaotic or rigid. This family organization helps it to achieve goals within a developmental time frame and to survive as a unit. Of all the changes in family life during the 20th century, perhaps the most dramatic and the most far-reaching in its implications-was the increase in the rate of divorce. The increase in marital dissolution has had major implications for the settings in which children are nurtured and socialized. The definition of dysfunctional family, however, differs widely among the studies, comprising more general definitions of negative rearing practices and altered family dynamics and specific and narrow criteria of family transition, socio-economic status and unhappy marriage. II. There are children growing up in situations where the interactions between family members are far from healthy. The dynamics of a dysfunctional family can range from the very bizarre to the sublimely subtle. Children who are developing both physically and psychologically are misfits. The sad part of this syndrome is that the children have very little say as to what goes into the formation of their own personalities. They have to play with the hand that is dealt. Too often society waits `until children have many years of physical or psychological abuse before trying to intervene. Once these children begin to manifest their dysfunctional behaviors, it is often too late or extremely difficult to turn them around. The key players in a dysfunctional family are, of course, the parents or parent. Dysfunctional parents come in all sizes and shapes, with the most obvious being the alcoholic, the abuser, and the mentally disturbed. There is, however, a more subtle level of dysfunction in families (Husain & Catwell 1992). Overprotective parents not only stifle the decision-making process with this kind of behavior, they are constantly making their children feel less than whole. Parents who always make decisions for their children-from deciding when they get up in the morning or when it is time for the bath-are creating individuals who rely on other to make their decisions-creating followers instead of leaders. In families where dysfunctional rules are rigidly adhered to, individual development and expression is discouraged. Children in these families may reach young adulthood less prepared to function in intimate relationships such as close friendships, dating and marriage. The quality of these premarital relationships contributes to one’s decision to marry, and strongly predict marital satisfaction (Amato & Sobolewski 2001). In families where highly dysfunctional rules have promoted unhealthy family process, future relationships may be negatively influenced. A considerable amount of money is being spent on the drug problem, but most of the money is going into law enforcement, incarceration, and rehabilitation programs. These are important areas that need funding; however, there seems to be little emphasis on prevention. If we could raise a generation of children who were psychologically healthy, who respected themselves, and had high self-esteem, they would have no desire to engage in self-destructive behavior. It is simple economics-supply and demand-if we do not demand or desire drugs and alcohol, then the profit motive erodes and suppliers will disappear. Even if we took drugs and alcohol off the streets, we would still have that segment of our population that is dysfunctional. These children are simply the products of their environment. If we are to change the way they view themselves and life, we must provide them with a healthy environment in which to grow and learn. Its’ time parents and guardians are held accountable for the behaviors of children (Amato 2000). Parents, who do not show a reasonable amount of love, respect, and discipline toward their children should be identified and be made to assume some of the consequences of their children’s behaviors. III. It is estimated that over seven million American adolescents-one in four-are extremely vulnerable to multiple high-risk behaviors and school failure while another seven million are at moderate risk (Amato 2000). In today’s society, adolescents are apt to become involved with damaging behaviors, particularly those associated with alcohol, drugs, sexual activity, sexually transmitted disease, and pregnancy. An authoritarian power structure is one in which parents impose their values upon their adolescent children. These children see the adults in the family as demanding and restrictive. Adolescents frequently have no alternative but to break the rules. Even as the adolescent grows older, authoritarian parents have difficulty renegotiating outdated rules. Individuals with divorced parents are at increase risk of experiencing psychological problems in adulthood. Although good reasons exit for assuming that the quality of parent-child ties mediates some of the long-term negative effects of parental divorce (Jekielek 1998). Unfortunately, along with these pressures, many young people lack guidance and support. The path to adulthood has been described as one of isolation. During adolescence, exploratory behavior patterns emerge. Many of these behaviors carry high risks and have resulted in an unprecedented number of alcohol-related accidents and school dropouts. The need to develop self-esteem and inquiring minds among our youth has never been more necessary. It is our belief that every youth in our nation, poor or rich, advantaged or disadvantaged, should have the opportunity to achieve success, not just minimum competence. This is the challenge to our society as a whole-our educational, community and social-support systems. However, it also is direct challenges to individuals to keep families maximize their potential. Unfortunately, many families are unable to cope with the problems faced by adolescents. Many adolescents are growing into adulthood alienated from others, and with low expectations of themselves. There is greater likelihood that they will become unhealthy, addicted, violent, and chronically poor (Amato & Sobolewski 2001). Equally disturbing is that adolescents from the more affluent communities are displaying similar problems. On the other hand, less advantaged families, in struggling to make a living, do not have the time to build family relationships. In a time of great change, many parents are confused about their roles and relationships and are less aware of the new temptations faced by their adolescents (Jekielek 1998). IV. Marital dissolution is a process that begins before physical separation and continues after the marriage is legally ended. These stressful circumstances are likely to impact negatively on children’s psychological adjustment. Consequently, the relatively high level of psychological distress among adult children who grew up in divorced families may represent a simple continuation of emotional problems that began in childhood. Parental divorce negatively affects the quality and stability of children’s intimate relationships in adulthood. The risk of marital disruption is higher for those who experienced parental divorce as children. Our culture presently provides largely negative role models for the divorcing family. Language for divorced families lacks the capacity to derail a present relational system except in terms of a past relationship. The dramatic role transactions and systematic reorganization necessitated by divorce puts stress on the whole family. This can bring on critical family dysfunction in all the major transitions. A dysfunctional family is defined as one in which the emotional needs of its members are not meet (Husain & Catwell 1992). It is assumed that this emotional abandonment has a deleterious effect on a child’s development. The explication of the various losses experienced by children from these families is common. These losses include, but are not limited to, the loss of one’s childhood, the loss of a relationship with oneself, the loss of security, and the loss of freedom. The loss of one’s childhood, however, is simply indicative of a second and more significant loss, that of a nurturant parental figure (Amato 2000). Rather than missing something they didn’t have, this loss is a longing for; and missing, an idealized and fantasy parent. Although parents in dysfunctional homes are physically present, they are emotionally absent, and therefore they are unavailable to function as nurturant parents. Unlike a child who experiences the actual death of a parent, who eventually finds a substitute parental figure, a child in dysfunctional home has no such substitutes. To compensate for this parentless home, children in dysfunctional homes may adaptively develop a fantasy parent, a good and nurturant parent, much like the invisible fantasy companion that so many young children create and enjoy. This fantasy parent is perhaps based on television characters or on characteristics of the parents of their peers. V. During the children’s adolescence, parent’s decision-making becomes even more difficult due to the complexity of such issues as discipline, schooling, and intimacy. The adolescents are constantly very vesting changes in the rules and in the process parents may disagree with each other. Adolescents are adept at recognizing this ambivalence and may play one parent against the other. Most of the problems seen in dysfunctional families with adolescents also occur in normal families; however the rate of dysfunction is much higher in families that have maladaptive methods of solving problems. In fact, in many dysfunctional families adolescence related issues are a continuation of prior parental difficulties. However, an implicit goal for every family, even a very unhealthy one, is the growth and preservation of its members. The family’s parameters undergo continuous evaluation as the adolescent goes through a period of change-physiological, cognitive, emotional or behavioral. This period of change necessitates a series of psychosocial adjustments within the family, the major one focusing on the adolescent’s primary developmental task of becoming independent from parents.

Painters Keys Community Essay Example | Topics and Well Written Essays - 500 words

Painters Keys Community - Essay Example These may all sound different from each perspective such as a painter might not be able to play the piano nor dance and a musician might not be able to paint, sculpt, or dance, but this fact does not alter the fact about art forms being related to one another. Just when a dance cannot be possibly performed without a piece – one that is a product of rhythmic and melodic tune - music is a necessity for a dance performance. Hence, a musical composer arranges his piece, which may be potentially used as a piece for a dance performance, while the choreographer relies his dance steps to the beat of the musical arranger. Likewise, a painter, a sculptor, and an architect, despite incongruity of their art forms, all agree towards the universal knowledge of lines, curves, and colors, which they use as a fundamental basis of their artwork. These are just few examples of how various artists function as a whole. The realm of arts takes a wide variety of forms in which people from various walks of life engage themselves for various reasons. One thing is certain though, that they undertake it for purposes of self-expression, entertainment, and appreciation enabling their rather drab existence become an artful and a less-menacing one. As artists express themselves through their artworks, they deliver a distinct essence of art appreciation rooted in history and social interaction. All artworks are thus, a product of both individual and social perceptions in which the artist partakes in his social surrounding and reflects this through his art. His art, whatever form it is, reflects the human condition, the social trend, and the human passion at the time it was created. It is to this end that various artists function as a whole in the realm of the arts. Another unifying factor of various artists is the incessant intent of the arts towards appreciation. This is one of the fundamental functions of the arts, if not ultimate, embodied in every piece of work as the

The Impact of Coffee on the Global Marke Essay Example | Topics and Well Written Essays - 4250 words

The Impact of Coffee on the Global Marke - Essay Example Consumer demand is on the rise for such coffee and as people continue to drink such coffees the quality of coffee is one issue that will not be overlooked (Myers, n.d). Coffee is also consumed for its value of inhibiting sleep. This usually enables individuals who were involved in an activity to continue even late in the night without the inhibition of sleep.  Additionally, Coffee is a source of employment for many people of the world. Coffee is said to be the second most traded product after Oil (Solange   et..Al, 2011).  Ã‚   This potentially means that it provides employment to many people at different levels. These include the famers who plant the crop, the people who transport the crop to the market, the people involved in the conversion of coffee from berries to the finished product, the individuals providing packaging for the coffee as well as the marketers, distributers, Warehouse operators and also the shipping companies and many more.  In addition, the impact of Cof fee has many positives about the provision of a beverage and employments at different levels.

How useful is the concept of semi-presidentialism for understanding Essay

How useful is the concept of semi-presidentialism for understanding the political regime of the Fifth Republic - Essay Example The first aspect worth analyzing is to what extent France meets Duverger’s first criteria: a president elected by universal suffrage. In 1962, the then French president Charles de Gaulle passed a constitutional amendment altering the presidential election from parliamentary to universal suffrage (Curtis 2004). This meant that the president of the republic would be elected by the population, and therefore had to become a strong and appealing individual leader. At the time, this benefited De Gaulle since he epitomized charismatic leadership and desired a system were the president wielded the majority of government power and responsibility. Universal suffrage gave constitutional power to the president, as he, by virtue of being elected by majority vote, now possessed similar legitimacy to that of a majority in the Assembly. Thus, 1962 marked the beginning of a shift of power from the Assembly to the President, and is even considered by Robert Elgie to be the point that establishe d the Fifth Republic as a semi-presidential regime.   The second criteria of Duverger’s definition of semi-presidential regime is that â€Å"(2) he possesses quite considerable powers† (Duverger, 1980:166 cited in Elgie:2009). Scholars such as Robert Elgie criticized Duverger for being too vague in his definition of semi-presidential regimes. For instance, Duverger underscores the fact that the president must possess considerable powers, but never expounds on this idea in order to establish what is deemed to be considerable. Reading further on Duverger’s other work such as A NEW POLITICAL SYSTEM MODEL: SEMI-PRESIDENTIAL GOVERNMENT (1980), Duverger defined the considerable powers saying that French Fifth Republic as â€Å"A country with an all-powerful presidency† (Duverger 1980:170). He justified this proposition by citing Article 16 which states

Children with Autistic Spectrum Disorder and Effective ways for their Essay

Children with Autistic Spectrum Disorder and Effective ways for their Educational Practices - Essay Example 25). . Nevertheless, all of the children who are diagnosed with a form of Autistic Spectrum Disorder have commonalities, and this paper explores what they are. Further, there are intervention strategies that can be successful in helping the autistic child negotiate the areas where he or she is most weak, and these are explained as well. What is Autistic Spectrum Disorder? Autistic spectrum disorder encompasses a wide range of the disorder, and there are different diagnostic categories for the syndrome, and these are Asperger’s syndrome, Kanner’s autism (classic autism), and â€Å"atypical† autism (Jordan, 1999, p. 1). The DSM-IV-TR states that the autistic spectrum includes autistic disorder, Asperger disorder, Rett disorder, childhood disintegrative disorder, and pervasive developmental disorder not otherwise specified (Ozonoff et al. 2003, p. 4). For purposes of expediency, the autistic spectrum will simply be known as â€Å"autism,† although Aspergerâ⠂¬â„¢s will also be delineated as such later in this paper Autism is a continuum, in that there are individuals with pure autism, which means that the symptoms described below are severe, to high-functioning, in which the symptoms are mild (Durig, 1996, p. 98). ... 19). One of the forms of autism is known as Asperger’s syndrome. Asperger’s syndrome is marked by social deficits, such as those seen in autistic individuals, yet language and cognitive abilities, at least early in life, are preserved (Klin et al., 2000, p. 25). While individuals with Asperger’s syndrome may not have impaired language, they will speak differently, such as children speaking like â€Å"little adults† by using a large vocabulary in a pedantic way (Mesibov et al., 2001, p. 12). Individuals with Asperger’s social deficits are less pronounced then autistic individuals, but they still have social difficulties. One reason is because individuals with Aspberger’s are generally unable to have a conversation, because they lack the ability to reciprocate. They will talk, but they will not listen. Because of this, they will have a difficulty making friends, and will often be teased (Atwood, 2007, p. 13). Individuals with Asperger’s also have difficulties with social conventions (Frith, 1991, p. 152), where an individual with Asperger’s has a desire to engage with others, unlike those with autism, but their capacity to engage with others is impaired by their social deficits (Rhode & Klauber, 2004, p. 33). As with autistic individuals, individuals with Asperger’s also have obsessive interests in different things, such as collecting facts and objects. They also tend to be hypersensitive to criticism (Schopler & Mesibov, 1998, pp. 12-13), and have a low tolerance level which leads o frustration easily (Dubin, 2009, p. 44). Not surprisingly, because individual’s with Asperger’s tend to be socially isolated and frustrated, therefore teens with Asperger’s run

Advice for the Critique of an Academic Journal Article

Advice for the Critique of an Academic Journal - Article Example is, the emphasis is on collecting various manifestations of INV, which the authors divide into three groups: â€Å"born global,† â€Å"born again global,† and â€Å"born international.† (Gabrielsson et al., 2014, p. 450). In the given theoretical framework, the authors use data from several case studies from mostly developing firms in knowledge-intensive sector. So, it is crucial to discuss validity, reliability, and transferability of the given support to the main idea. Based on the presented theoretical assumptions, the discussion seems reasonable. In particular, the examples of real activity fit the theoretical assumptions of its entrepreneurial features. In other words, case studies make the findings on causal relationship between the enterprise and opportunism to be â€Å"really about what they appear to be about† (Saunders et al., 2009, p. 157). Although, the presented data has doubtful actuality. Even though the article was published in 2014, the authors finished their interviews with founders and CEOs before 2011 (Gabrielsson et al., 2014, p. 451). Thus, the data omits recent challenges; for instance, the impact of global economic crisis in 2012. Nevertheless, analysis is deep and comprehensive. In fact, the authors highly value their choice of multiple case studies as they â€Å"are expected to be valid† (Gabrielsson et al., 2014, p. 451). So, the illustrative capacity of above-mentioned evidence is strong, as it has convincin g literature basis and numerous sources of practical evidence; in fact, it seems to be a pioneer research combination in the field. As for reliability of the evidence, it reveals its limits. By being the only source of presented data, multiple interviews with key actors make the selection bias is inevitable. In this context, classification of paths imposes the limit on number of cases. At the same time, this approach increases an accuracy of presented data. Actually, authors achieved their aim to create â€Å"a more holistic and contextual

Finance International Expansion Essay Example | Topics and Well Written Essays - 1000 words

Finance International Expansion - Essay Example Major differences exist in the economic, political, socio-cultural, technology, competitive and financial environments of different countries. These need to be taken into account in planning the overseas expansion. Expansion decision has to be made after proper consideration of all strategic and operational issues arising from within international milleu. Decisions need to be made concerning a wider range of both Strategic and Operational Issues. Key Strategic Issues that need to be addressed include assessing our company's readiness to internationalise which includes the suitability of your product or service for overseas markets and the extent of local adaptation required; choosing the most attractive foreign market(s) and the best entry strategy to adopt; international pricing, distribution and promotion strategies; organising and controlling our overseas activities. Operational issues include export paperwork and documentation; legal and financial issues; finding and managing overseas partners and so on and are ultimately transferrable into financial and legal consultancy fees and travel expenses. Whether the company intend operating through agents/distributors or establish its own overseas sales subsidiary, the burden of control-related activities and costs is heavier than at home making it much more difficult to monitor and control overseas activities. There are significant financial risks associated with doing business abroad, including the risk of higher indebtness, risk of not getting paid at all and currency fluctuations-related risks. Further, when going international we will need to be sensitive and empathetic to the local political and cultural environments of different countries. That entails higher management and consultancy costs and will unltimately produce to elevation of cross-cultural and political analysis to the level of decision making tool. The competitive environment may be quite different from what we are used to at home. In whole, as a consequence of the above, international marketing is more costly and time consuming than domestic marketing and you will need to take a long-term view to achieve sustained profitability. The Barriers US Computer Systems companies, especially medium sized enterprises, face a number of barriers or obstacles when going international. These may include: Psychological Barriers including lack of international/global orientation; short-termism; product or technology rather than customer led 'mindset'; lack of commitment to international markets; exporting seen as 'too risky', 'not for us' or 'too much trouble'; the 'fear factor'. Organisational Barriers including limited resources (financial and managerial); lack of knowledge of foreign markets; lack of international experience; lack of formal training in international marketing; problems in finding suitable overseas partners; ability to compete away from home. Operational Barriers relating to export documentation and paperwork; language problems; payment delays and risks etc. Product/Market Barriers in the sense of overseas market demand particularities, i.e. that product or service may not be suitable for overseas markets without major and costly adaptation; the product or service may not have a unique competitive advantage abroad; further, problems in

Negligent misstatement is based on a special relationship being Essay

Negligent misstatement is based on a special relationship being proven. By discussing relevant case law, explain how this - Essay Example Special Relationship in negligent misstatement Special relationship in law is regarded as a situation in which a party relies on a professional’s skills and experience of a professional to undertake certain actions or omissions. It is worth noting that professionals are people with impeccable knowledge and skills on myriad of issues depending on their area of expertise. Charlesworth (2008) says that due to their unique skills and experience, majority of people usually depends on their input before they act. Whenever one seeks the services of another in a professional capacity, the professional has a duty of care and as such should offer his advice or act with caution. In court proceedings where the subject matter is negligent misstatement, the court considers several factors in order to determine if there is any form of material misstatement. In fact, the courts consider three critical elements whenever they are dealing with the issue of special relationship in the context of negligent misrepresentation. One such factor is that the plaintiff relied on the skills and judgment of the defendant to make certain acts or omission. The other element is that the defendant ought to be aware or was aware of the fact that the Plaintiff was relying on him to make certain acts or omission. ... The court of appeal established that the case qualified for negligent misrepresentation by the defendant and that there existed special relationship between Dick Bentley Productions and Harold Smith. The case, therefore, satisfied all the requirements of material misrepresentation, which include the fact that the plaintiff, Harold Smith Ltd, relied on the skills and judgment of the defendant, Dick Bentley Productions, to make certain the decision of purchasing the Bentley. The other element is that the defendant, Dick Bentley Productions, was aware of the fact that the Plaintiff, Harold Smith Ltd, was relying on him to make certain acts or omission. Finally, the circumstances reasonably alluded to the fact that the defendant was aware that the defendant was relying upon his advice. The defendant was a dealer in Bentley and as such; he was in a better position to tell the correct mileage of Bentley because he was a dealer in Bentley. For the special relationship to hold in court proce edings involving negligent misstatement there is need to prove that, the defendant was a professional who had the knowledge, experience, and judgment on the subject matter. In Oscar Chess Ltd v Williams (1957) 1 WLR, the defendant had falsely stated the age of the car to the dealer in a part exchange transaction. The court held that although there was a statement, the defendant was not in a position to tell the true age of the car to the plaintiff since the former was not a professional in the field. The statement of the defendant was therefore held to be representational. In his judgment, the judge alluded to the fact that the plaintiff could have at least bothered to verify the details that were

Reading Fluency and Its Effect on Reading Comprehension Essay Example for Free

Reading Fluency and Its Effect on Reading Comprehension Essay As an elementary teacher, I have often thought reading fluency plays a large role in a child’s reading development. Few reading programs give fluency the recognition it deserves. Reading fluency has been a prominent and reliable benchmark for me, even when students have comprehension difficulties. Once fluency is assessed, the results were used to place students in their reading ability group. Often times, the fluent readers were placed in the high ability reading groups. In the past, our district used a reading program that gave very little focus to reading fluency and few strategies for improvement. It assessed fluency based on rate and accuracy—not prosody. The previous reading series also failed to assess the students’ comprehension after they read independently. The non-fluent readers spent so much effort on word identification; it is difficult for them to enjoy reading the selection. I believe this is one reason they enjoy being read to. Students can comprehend a story when it is read aloud to them, but it is their lack of fluency that inhibits comprehension when it is their turn to read. A current goal in our school improvement plan is to improve reading fluency; therefore, in this review of literature, I will examine reading fluency by focusing on how it affects comprehension. Literature Review The attention given to reading fluency has fluctuated throughout the years in education. It is currently gaining recognition and once again becoming an advertised component in most reading programs. According to Avanchan (2010), fluency is a critical element of reading and should be taught in every school. This Literature Review will focus on the following research questions: 1. What is reading fluency? 2. What strategies can be used to improve reading fluency? 3. How does reading fluency affect reading comprehension? What is reading fluency? Reading fluency is defined as the ability to recognize words rapidly and accurately. Under the reading fluency umbrella, there are three main components of fluency: accuracy, rate, and prosody (Nathan Stanovich, 2001). Reading accuracy is the ability to decode and recognize words correctly. Without reading accuracy, a young reader cannot interpret the author’s intent (Evanchan, 2010). To be considered an accurate reader a student has a strong knowledge of the alphabetic principle, ability to blend letters, and a significant bank of high frequency words (Hudson, Lane, Pullen, 2005). Reading rate refers to the speed one can read at with fluidity (Evanchan, 2010). This component of reading fluency is often described as a reader’s automaticity. With automaticity, a reader can effortlessly identify words in text (Evanchan, 2010; Hudson et al. , 2005); however, accurate word recognition alone is not a strong indicator of fluency. Speed also needs to be heavily considered. (Evanchan, 2005). Hudson et al. (2005) describe prosody as â€Å"the music of oral language† (p. 704). Prosody is what makes a reader enjoyable to listen to, because it includes appropriate phrasing, intonation, stress patterns, and duration (Hudson et al. , 2005). Prosodic reading suggests the reader has connected to the literature and understands what is being read (Hudson et al. , 2005). What strategies can be used to improve reading fluency? Numerous strategies can be used to improve reading fluency (Evanchan, 2010). One strategy that continues to hold valor is repeated reading, which is when students continuously read the same passage until they have reached a level of fluency (Mastropieri, Leinart, Scruggs, 1999). Once they have reached the predetermined level of fluency, they move to a more difficult passage. Hudson et al. (2005) suggested repeated reading is highly recommended for improving of fluency because it concentrates on all components of fluency: accuracy, rate, and prosody. Reader’s theater is another strategy where children practice repeated reading (Evanchan, 2010). Reader’s theater brings a new, more exciting approach to repeated practice. Like repeated reading, reader’s theater focuses on all three elements of reading fluency. Reader’s theater requires students to reread, memorize, and perform the text, which are key components to improving fluency. Adding dramatic performance to a student’s reading experience will positively affect the student’s expression, or prosody, a key component to reading fluency (Nathan Stanovich, 2001). Modeling fluency is essential so students can better understand what reading fluency sounds like. Proper modeling focuses on accuracy, rate, phrasing, and prosody (Worthly Broaddus, 2001). Evanchan (2010) suggested proper modeling gives students exposure to vocabulary above their independent reading level. Modeling allows students to be engaged with text they may wrestle with independently, and comprehension is also enhanced (Worthly Broaddus, 2001). The student’s engagement and evidence of comprehension suggests students’ listening comprehension level is at a higher level than their independent reading levels (Evanchan, 2010). How does reading fluency affect reading comprehension? There are five essential components to reading. They are phonemic awareness, phonics, fluency, vocabulary, and comprehension. Evanchan (2010), referred to the components as links in a chain, and comprehension is the link that secures the chain; however, if one of the four other components are missing, the ultimate goal of comprehension cannot be obtained. Before a higher level of reading can be obtained, a student must be able to decode the words in text (Nathan Stanovich, 2001). Without word recognition, a reader is likely to misinterpret the author’s intent. Misinterpreting the text can develop a barrier for comprehension (Hudson et al. , 2005). When looking at fluency on a larger scale, developing automaticity forms the bridge between reading fluency and comprehension. (Pikulski Chard, 2005). Although reading comprehension is not solely achieved through reading fluency, it certainly reflects upon it (2005). Automaticity and comprehension are intertwined and should not be separated during instructional modeling (2005). Doing so may affect the ultimate goal of developing meaningful responses to the text (Applegate, Applegate, Modla, 2009). Nathan and Stanovich (2001) and Hudson et al. (2005) agreed non-fluent readers have a difficult time focusing on comprehension because their cognitive capacity is limited, and they use all of their energy to decode words. Students who have efficient word identification and have achieved automaticity free up processing space so their cognitive resources can be used for comprehension and higher order thinking (Hudson et al. , 2005). Conclusion. There is a significant amount of information that acknowledges reading fluency’s effect on reading comprehension. Through automaticity and prosody, a bridge can be built between reading fluency and comprehension. Reading fluency needs to become an instructional focus in the classroom. While rate seems to get most of the focus, all three components of reading fluency need and deserve to be addressed equally. The earlier reading fluency strategies are administered, the greater chance the student has to becoming a reader who can respond to literature thoughtfully and with meaning, which is the ultimate goal.

Effect of Mutant EDA-A1 Gene on Huvecs

Effect of Mutant EDA-A1 Gene on Huvecs Effect of EDA-A1 gene mutant on proliferation and cell cycle distribution of cultured human umbilical vein endothelial cell Running title: The effect of mutant EDA-A1 gene on HUVECs. Ke Lei, MM; Lunchang Wang, MD; Bing Ma, MM; Ping Shi, MD; Longjiang Li, MD; Tuanjie Che, MD; Xiangyi He, MD Highlights: EDA-A1 gene mutant significantly decreased proliferation of human umbilical vein endothelial cells (HUVECs). HUVECs of mutant group were blocked at G0/G1 and S phase. HUVECs of wild group accumulated in S phase and decreased in G2/M phase. Abstract Background: To investigate the effect of ectodysplasin A gene (EDA-A1) on proliferation and cell cycle of human umbilical vein endothelial cells (HUVECs) and explore the possible mechanism underlying this process. Methods: Recombinant eukaryotic expression vectors pcDNA3.1(-)-EDA-A1-M/W (mutant, M; wild, W) containing the coding sequence of EDA-A1-M/W were transfected into HUVECs. EDA-A1-M/W genes were amplified by reverse transcription polymerase chain reaction (RT-PCR), and the proteins were detected by western blot. Then MTT assay for cell proliferation of HUVECs in each group was performed and cell cycle was detected using flow cytometry. Results: The EDA-A1 gene and protein were detected respectively by RT-PCR and western blot in HUVECs transfected with pcDNA3.1(-)-EDA-A1-M/W, but not in HUVECs transfected with empty plasmid pcDNA3.1(-) (control group) and cells without transfection. Compared with control group, EDA-A1 gene mutant significantly decreased proliferation of HUVECs and the inhibition rate was 45.70% (PEDA-A1 gene did not cause such growth inhibition (P>0.05). A significant increase of the G0/G1 and S fraction was seen in the HUVECs of mutant group, compared with wild group with an accumulation in S phase and a concomitant decrease in G2/M phase population (P Conclusion: Compared with the wide-type, the mutant EDA-A1 gene could inhibit the proliferation and cell cycle of the HUVEC. Key words: EDA-A1 gene; Mutant; Human umbilical vein endothelial cell; Cell cycle; Proliferation Introduction Hypohidrotic ectodermal dysplasia (HED), also called anhidrotic ectodermal dysplasia (AED) or Christ-Siemens-Touraine Syndrome, is a kind of X-linked recessive genetic disease (XLHED) (1). HED is a rare congenital genetic disorder with a birth incidence of 1/100,000-1/10,000 (2, 3). It is characterized by the diminution or absence of eccrine sweat glands, oligodontia and peg shaped teeth and sparse hair (1, 4). Previous study indicates that XLHED is caused by the ectodysplasin A gene (EDA-A1) mutant (5). EDA-A1, a major causative gene of HED, locates in Xq12-13.1 and encodes a novel tumor necrosis factor (TNF) ligand family protein ectodysplasin A (EDA-A1) and this protein is associated with the nuclear factor-ÃŽ ºB (NF-ÃŽ ºB) signaling mechanisms (5-9). Bayes M et al. (10) indicates that the full-length of EDA-A1 is 5296bp (http://www.ncbi.nlm.nih.gov/, AH007059, Gene ID 4007891), the open reading frame (ORF) of EDA-A1 is 1176bp, and it encoding the protein with 391 amino acids (EDA-A1, GeneID1896). Studies showed the combination of EDA-A1 and ectodysplasin receptor (EDAR) could promote programmed cell death and active the signaling of NF-ÃŽ ºB (8, 11). Recently, the related research on HED are mostly for mutation analysis of EDA-A1, and more than 100 mutations in the EDA gene have been reported to cause XLHED up to now (12, 13). However, there have few reports relating to the function of mutant EDA-A1, and the exact pathological mechanism of mutant EDA-A1 on HED is still unclear. In the present study, EDA-A1 mutant (pcDNA3.1 (-)-EDA-A1-M) and wild type (pcDNA3.1(-)-EDA-A1-W) eukaryotic expression vector that we used were constructed in our previous study (14). Then the function of transfected EDA-A1 and its mutant for cell proliferation and cell cycle of HUVECs were analyzed. The aim of this study was to investigate the effect of EDA-A1 on proliferation and cell cycle of HUVECs and explore the possible mechanism underlying this process. Material and Method Cell culture HUVECs were kindly provided by professor Wang chunming (Lanzhou University, China). HUVECs were cultured in RPMI-1640 (Huamei Company, Shanghai, China) Medium. The medium were consisted of 10% fetal bovine serum (FBS) (Evergreen Company, Hangzhou) and 100U/ml penicillin/streptomycin. All these cells were maintained in humidified incubator of 5% CO2 at 37à ¢Ã¢â‚¬Å¾Ã†â€™ (0.25% trypsin digestion overnight). Inverted microscope was used for the cell morphology investigation. All the experiments were performed at least in triplicate and repeated at least twice. Plasmid extraction EDA-A1 mutant (pcDNA3.1(-)-EDA-A1-M) and wild type (pcDNA3.1 (-)-EDA-A1-W) eukaryotic expression vector that we used were constructed in our previous study (14). Totally 3ÃŽ ¼l mutant (M) and Wild-type (W) plasmid DNA was extracted respectively from transfected HUVECs, followed by the sterile deionized water diluted to 1ml. The values of à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹A260nm and A280nm were measured by UV spectrophotometer. Plasmid DNA concentration (ÃŽ ¼g / ÃŽ ¼l) = A260 Ãâ€" dilution factor Ãâ€" 50/1000. The plasmid DNA (positive recombinants and empty control) was precipitated by ethanol. Then the DNA pellet was resuspended in sterile deionized water. Cell transfection Cell transfection was carried out according to the instructions of QIAGEN-Effectene Transfection Reagent Kit (QIAGEN). Transfection was carried out when the cell density was up to 70% after 24 hour-cell passaging. Cells were transferred into a complete medium (CM) 2 hours before transfection. Totally 2.5 µg mutant (M) and Wild-type (W) plasmid DNA was slowly added to the 2 M CaCl2 solution (stand for 10 minutes). DNA-CaCl2 solution was slowly added dropwise to the 2 Ãâ€" HeBS (stand for 30 minutes) until the precipitation of tiny particles. The precipitate was uniformly dropwise added to the culture flasks. After a 12 hours growth under standard conditions, cells were washed 2 times with HeBS, followed by the cultured in CM. HUVECs transfected with empty vector were used as the control group. Semi-quantitative real-time PCR To identify the expression levels of EDA-A1 in HUVECs, semi-quantitative real-time PCR (SqRT-PCR) analysis was performed. Total RNA was extracted from cultured cells in each group (cultured for 48 hours) by using reverse transcription (RT) kit (Fermentas Company), followed by the EDA-A1 primers designation (Primer Premier 5.0 software) and synthesis (Shanghai Biological Engineering Company ). The primers used were as follows, EDA-A1 (408bp): 5’- CGC AGG ATC CAT GGG CTA CCC GGA GGT -3’ (forward) and 5’- ATT AAG CTT GCC AAG CGG GCA CCA GGG AGA C -3’ (reverse), ÃŽ ²-actin (230bp): 5’- ACG CAT TTG GTC GTA TTG GG-3’ (forward) and 5’- TGA TTT TGG AGG GAT CTC GC-3’ (reverse). The 50ÃŽ ¼l PCR reaction system were: cDNA template (2ÃŽ ¼l), 10 Ãâ€" PCR Buffer (5ÃŽ ¼l), dNTP (1ÃŽ ¼l), primer (up and downstream, 1ÃŽ ¼l), Taq DNA polymerase (1ÃŽ ¼l), ddH2O (39ÃŽ ¼l). Products were subjected to electrophoresis (1.5% agarose gel, 120V, 90mA). Western blot analysis For Western blot analysis, proteins were extracted from HUVECs in each group. Proteins were collected after cell lysis. Protein concentration was determined using the Bradford dye-binding method (15). The proteins were separated by SDS-PAGE and transferred to the 0.45ÃŽ ¼m pore size nitrocellulose (NC) membrane (RPN303E, Amersham Company). NC membranes were blocked with TBS buffer (5% milk and 0.5%-Tween) for 1 hour (37 °C). Then, the membrane was incubated overnight at 4à ¢Ã¢â‚¬Å¾Ã†â€™ with the rabbit antibodies EDA-A1 and ÃŽ ²-actin (1:200 dilution with TBST solution), followed by incubation at room temperature for 1h with an anti-rabbit secondary antibody (Sigma). Finally, the expression levels of the target proteins were visualized withchromogenic substrate. MTT assay for cell proliferation detection To determine the proliferation of HUVECs in each group, the 3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide (MTT) assay was performed. The 24 hours-transfected and untransfected cells were seeded into 96-well plate with inculation density of 5000 cells/well and incubated at 37à ¢Ã¢â‚¬Å¾Ã†â€™. After 12 hours, 100 ÃŽ ¼l serum-free DMEM was added in each well. After 72 hours, 20 ÃŽ ¼l MTT was added into each well to continue incubation at 37à ¢Ã¢â‚¬Å¾Ã†â€™(4 hours). Then, the medium was removed and the precipitation was dissolved in DMSO. The absorbance at 560 nm was measured by SpectraMax 190 microplate reader (Moteular Devices Company) for colorimetric analysis. Inhibition rate of cell growth was calculated (n=10) based on the experimentally measured absorbance value (OD value). Cell cycle analysis Flow cytometry was used to detect the cell cycle.After incubation for 48 h, the cells were collected and washed with cold PBS. The washed cells were fixed in 70% cold ethanol with incubation overnight at 4à ¢Ã¢â‚¬Å¾Ã†â€™. To stain the cells, prodium iodide (PI) solution was added. Flow cytometer (Coulter Epics XL, Beckman Coulter Company) was used to analyze the samples. Cell Quest software was used to analyze the cell percentage of G0 / G1 phase, S phase, and G2 / M phase. Statistical analysis All assays were performed in triplicate and datawere expressed as mean values  ±s.d. The SPSS 13.0 software employing ANOVA was used to analyze all data which expressed as mean ±SD. P values less than 0.05 was considered as significantly different. Results EDA-A1 expression pattern in HUVECs influenced by plasmid-mediated transfection To identify the expression level of ED1-A1 in HUVECs transfected with vector pcDNA3.1(-)-EDA-A1-M or pcDNA3.1(-)-EDA-A1-W, the RNA samples with an OD260/OD280 ration of 1.8-2.0 were chosen for RT-PCR. The HUVECs with pcDNA3.1(-)-EDA-A1-M or pcDNA3.1(-)-EDA-A1-W transfection showed a band nearly 400 bp compared with control using semi-quantitative PCR and primers specific to EDA-A1 (Figure 1). Additionally, ÃŽ ²-actin band between 200 bp and 300 bp have been seen in all the groups. Then, EDA-A1 protein expression in HUVECs were detected by western blot. Figure 1 shows that the EDA-A1 protein was expressed in the transfected cells with pcDNA3.1(-)-EDA-A1-M or pcDNA3.1(-)-EDA-A1-W vector, however, it could not be achieved in control group. In conclusion, the EDA-A1 was expressed in HUVECs after exogenous delivered of EDA-A1, but not in the un-treated control cells. Overexpression of EDA-A1 affects HUVECs proliferation To elucidate the effect of EDA-A1 on HUVECs proliferation, the MTT assays were performed. As shown in Figure 2, the HUVECs viability at 96 h transfection was decreased significantly in the mutant group by comparison with wild type and control. The proliferation of mutant group cells was suppressed by 45.7% compaired to control, while the wild type group was suppressed by 16.0% (Table 1, Figure 3). EDA-A1 overexpression regulates the cell cycle of HUVECs To determine the role of plasmid-mediated EDA-A1 transfection in cell cycle of HUVECs, the flow cytometry was used (Figure 4). We observed that 25.45  ± 1.89 % cells were arrested at G0/G1 phase of cell cycle in the mutant group compared with 20.37  ± 0.6% and 20.30  ± 0.68% cells in wild type and control groups, respectively (Table 2). During S phase, both mutant and wild type groups showed significantly higher cell percentages (14.80  ± 1.45% and 12.4 0  ± 1.75%) than that of control (8.55  ± 0.57%). However, both transfection groups had lower cell percentages than control in G2/M phase. The lowest cell percentage with 62.15  ± 1.94% was showed in the mutant group during S phase. We could conclude that the cell cycle distribution in G0/G1, S, and G2/M of HUVECs were regulated by EDA-A1 overexpression. Discussion HED characterized by impaired development of hair, eccrine sweat glands and teeth is caused by mutations in the EDA-A1 gene (3, 16). Recently, the related research on HED are focused on the mutation analysis of EDA-A1, however, the exact pathological mechanism of HED caused by mutant EDA-A1 is still unclear (17). In this study, we investigated the effect of HED related gene EDA-A1 on proliferation and cell cycle of HUVECs. The results showed that mutant EDA-A1 gene significantly decreased proliferation of HUVECs (P EDA-A1 protein, a type à ¢Ã¢â‚¬ ¦Ã‚ ¡ transmembrane protein, is one of the TNF ligand family members involved in ectodermal development (18). EDA-A1 contains a TNF-like domain (aa: 245–391), a collagen domain, and a furin protease recognition sequence (7, 8, 19-21). The TNF-like domain is necessary and sufficient for receptor molecule EDAR binding (22, 23). Furthermore, EDA-A1 has been shown to specifically bind to EDAR, which could promote programmed cell death and active the signaling of NF-ÃŽ ºB (8, 11). In our study, the reason why EDA-A1 mutant could inhibit the proliferation and block the cell cycle progression in G0/G1 phase and S phase of HUVECs might be the change of protein spatial configuration and biological activity that caused by the EDA-A1 gene mutation and the changed protein could not combined with EDAR and thus inhibit the signaling of NF-ÃŽ ºB. Maria et al. found that HED was related with the blocked signaling pathway of NF-ÃŽ ºB (9). Pascal et al. found th at point mutations in the TNF-like domain of EDA-A1 strongly decreased EDAR binding to EDA-A1 by altering the folding of EDA (21). Moreover, the substitution of Gln306 with Pro in our study was found to be located in the TNF-like domain of EDA-A1 and may influence the epithelial signaling pathway required for the normal ectodermal development through altering the topology of EDA, which is consistent with previous study. HUVECs are cells derived from the endothelium of veins from the umbilical cord, and they are often used as a laboratory model system for the study of the function and pathology of endothelial cells (24). Some studies showed that during vascular development and pathological angiogenesis, the maintenance of blood vessel homeostasis and its functional execution depend on the integrity of vascular endothelium, which is affected by proliferation, migration and apoptosis of endothelial cells (25, 26). Furthermore, Jie et al. showed that recovery of injured endothelial cells through regulated endothelial cell proliferation plays significant roles in thrombosis disease (27). In our study, mutant EDA-A1 decreased the proliferation of HUVECs, therefore, we suspected that pathological mechanism underlying HED caused by EDA-A1 may be the growth inhibit of endothelial cells which could lead to the defection of eccrine sweat glandsis. Despite of all results mentioned above, there were still some l imitations in the present study, whether the EDA-A1 mutant blocked the combination of EDA-A1 with EDAR required further experiment. In conclusion, our study revealed EDA-A1 gene mutant could inhibit the proliferation and cell cycle of HUVECs. We explored the mechanism of HED caused by mutant EDA-A1. The substitution of Gln306 with Pro may influence the epithelial signaling pathway required for the normal ectodermal development through altering the topology of EDA, which could impair the binding of EDA-A1 to EDAR and further inhibit the signaling of NF-ÃŽ ºB. Our finding broadens the spectrum of EDA-A1 mutations and may help to understand the molecular basis of XLHED and aid genetic counseling.

degenerate characteristics of dracula :: essays research papers

Degenerate Characters of Dracula In the novel, Dracula, Bram Stoker puts together a variety of characters with several characteristics that are unique and somewhat alike in many ways. One way that some of the characters are similar is that they show signs of being a degenerate. A degenerate is a person who has sunk below a former or normal condition and lost normal or higher qualities. These people most likely have mentally and sometimes physically become deteriorated to the point where they no longer can think and function as a normal person would. Two characters in the novel that stand out as degenerates are Dracula and Renfield. Both are degenerates in their own ways and also have characteristics that are in some ways the same. They follow most of the traits that degenerates contain and portray it throughout the novel. The best way to imagine a degenerate person would be to think of people on death roe in prison. The ones that aren’t remorseful for what they did, and could care less about what others think. They do not know what is right from wrong, and even if one tried to explain it to them, they couldn’t figure it out. Degenerates have no common sense, let alone a functioning brain. They are most definitely missing a few screws in there heads. These two characters of Dracula and Renfield both have a lot of these traits that degenerates consist of. Dracula most definitely contains degenerate characteristics throughout the novel. He has a lack of compassion for people’s well being, and has signs of selfishness. Vampires fit under the degenerate theme very well. How he became a vampire we are not sure, although Van Helsing calls him King-Vampire, because of his consistency and power driven obsessions towards his cravings. His powers include a wide range of abilities in which some are beyond the powers of the other vampires or immortal people in the novel. Degenerates are predestined to crime and don’t know why it is wrong. Van Helsing wrote of Dracula by saying, "The Count is a criminal and of criminal type. Nordau and Lombroso would so classify him, and qua criminal he is of imperfectly formed mind" (Stoker chapter 28). With all his killings and bites he proceeds on people, Dracula fights the degenerate theme. Renfield as well has qualities and characteristics of degenerates throughout the novel.

17th century english writers Essays -- essays research papers

The Pen Is Mightier Than The King The 17th century saw a king’s head roll and an English Caesar sit the throne, in the midst of all of this a new class was rising. England in the 17th century was rife with change, there was much work to be done before the industrial revolution could fully grip the nation. For hundreds of years the monarch had dominated the political landscape, now that was changing radically. Although their remained a Monarch in power for most of this period they had seen their powers limited to the point of reducing them to the status of figurehead. As farming techniques and technology had improved, the population in England had increased steadily and the use of this new technology created a new class in society.(1) This merchant class was on the rise due in large part to the captured markets in North America and the West Indies which had made many a merchant richer than their aristocratic brethren. The British Parliament had seen its power expand over the last hundred years and would continue that trend in the 17th century finding itself with the power to behead even the king.(1) As Parliament flexed their new found muscle the king was forced to find the funding for his political intrigues among the new merchant class. In addition to this new found monetary prowess the middle classes had been exposed to a rich variety of philosophers who espoused the right of the people to rule themselves.(1) Revolution in the New World and in parts of Europe increasingly made the lower classes aware of their right to self-governance. The parliament a representative of the people showed its power in the 17th century by enacting the â€Å"Glorious Revolution† and crippling the English monarchy for the rest of time.(1) Indeed in the next century the French Revolution would show that not only a government body had the power to remove royalty, the common people could also spill royal blood. As a result of this change in the class structure Monarchs and parliament where forced to recognize the power of the common people and they would from then on need to seek the peoples favor. The danger of an uprising was quite real and could not be controled by marshal means, as there was no standing police force or army.(1) In addition leaders of the time where selected by birth and not by political prowess and as such many of them lacked the eloquence to persuade the pe... ... lost their power and the war ended soon after this publication.(1) Each of these men has come to be associated with literary greatness and deservedly so, however at the time of their death they may not have felt the sense of accomplishment that they had earned. With the possible exception of Milton the early 17th century authors were limited both in the ideas that they could legally express and in the career opportunities that they could pursue, these men Dryden, Locke and Milton paved the way for the later authors and the freedoms that they enjoyed. In all of their cases they came from modest middle class backgrounds and were educated with money earned by their merchant class parents. The leaders of their time sought them out for this very reason as it allowed them to more effectively communicate their point of view to the increasingly powerful middle class. Although the rulers who sought to use them for their skill in communication may have gained some temporary benefit from their services, it is all subsequent English speaking authors who have be nefited the most from their labors in that they do not have to chain themselves to the prevailing sentiment in society to be heard.

Assessment Plan for Unit Cu697 Handle Mail Criteria 4.1 †5.2 Essay

4.1 At Proactive Personnel we always use Royal Mail to send out our mail our packages. The options we use to send out our outgoing mail are 1st class, 2nd class and special delivery. The way we are able to tell what mail needs to go 1st, 2nd or special delivery is by our employees placing the mail in the specific trays to which they need, where as special delivery is known by ‘rec’ been wrote on the mail. 4.2 The way our postage prices are worked out is by using the Royal Mail franking machine. We choose the option that we require for the mail, then we weigh the mail/package on the scale on the franking machine to which we are then given a price. Once this is done we simply place the mail under and the machine stamps the mail. If the mail is too big there are special stickers used which get stamped and stuck on the package. 4.3 At Proactive Personnel we do not require the use of a courier service. If we ever did need to use one there are numerous companies ranging from D HL to Fedex that we could use. If we had a large parcel that needed to be delivered we would pay for the company to come collect it and then deliver it to the destination. The cost involves the labour done by the driver, the fuel and the safety of the package. 4.4 This is covered in 4.1 4.5 This is covered in 4.2 4.6 When franking the post and handling the mail we do not record the post, however we do occasionally have to top up the franking machine. This is done by an internet connection set up to the bank account. Once the machine is topped up we make a receipt using the franking machine these are then stored, to which we can see how much was used in a period of time and compare them. 4.7 The post here at Proactive Personnel is sent and received daily the quantities vary. We usually send out the post nearer the end of the day depending on how much there is to stamp it can vary from one hour before to 15 minutes before the end of the day. Wednesday we usually send the payslips out, so there is a large quantity which usually takes a while. 5.1/5.2 During the process of the all above numerous problems can happen. The problems can be the franking machine running out of ink, a letter that has been left behind, post being stamped the wrong price.

American Movies of the 1920’s

Running head: AMERICA AND THE MOVIES OF THE 1920’S February 13, 2012 US HIS II ABSTRACT The movies of the 1920’s provided one of America’s most forms of entertainment after World War One. Americans were able to spend a little extra and enjoy such events as they were not devastates during with war. The movies for the American people began soon after the invention of automobiles. The movies provided communications and entertainment and soon began to open the American people to ideas of a different lifestyle on the screen. Some great actors and actresses came from this era.One of the being Charlie Chaplin, who with his charm, wit and forms of acting entertained the American people. The years following the devastating war take place prior to 1920 and fortunately left the United States unharmed. The United States was therefore able to experience a decade of peace and prosperity following one of the most devastating wars. One of the reason’s America was able to prosper was because technology played a vital part in bringing the economic and culture prosperity that America experienced in the 1920’s. New advancements, new inventions and the discoveries improved American lives in numerous ways.The combination of an increase in American recreation and the invention of the automobile helped in bringing success to the movie industry. Early movie attendance was low due to the distribution of theaters. As soon as the automobile was more popular, transportation was less of a hassle and movie attendance increased. The history of film spans from the early part of the nineteenth century. Motion pictures developed gradually from carnival novelty to one of the most important tools of communication and entertainment. Many of the films in the 20th century were silent.In the silent era of film, marrying the image with sound was not possible for the inventors and producers. For the first thirty years of the history of film, they were silent, and somet imes were accompanied by live musicians and sometimes sound effect and commentary were spoken by the showman. In the earliest silent films the actors were responsible for method acting or pantomime to portray their feelings to the audience. This in itself took much talent from the actors and actresses to help the audience feel the total impact of the movie.The movie industry became a huge part of American industry in general. Movies became America’s favorite form of entertainment. â€Å"Early movie stars such as Charlie Chaplin, Mary Pickford, and Douglas Fairbanks became idols to the American people who set trends in clothing and hairstyles† (James, 2009). Although the movies were a huge part of American life, some negative roles came from the movies. Actress Clara Bow, known as the â€Å"jazz baby† was enticing in the movies, and she soon became a cultural icon, who women accepted as their idol.The silent movie â€Å"It† was a huge success for Clara and millions of girls across America soon began imitating her style. Another famous person in the movies of the 1920’s was Charlie Chaplin. Chaplin was one of the greatest and most loved movie stars. He was known for his slapstick acrobatics. Chaplin was able to keep the attention of the audience by creating an environment and walk around it until something natural happened. He used overdramatic acting and lots of emotion. He helped the audience with knowing what the film was about by his demonstrations.The advent of technology helped the success of the movie history. Life was easy and convenient due to the industry of movies that took place during the 1920’s. The American people had dealt with the happenings of the war, and now they were able to relax and enjoy the newer things that life had to offer. Movies were the biggest form of entertainment during this time. REFERENCES Henrietta James A. , et. al. America: A Concise History. 4th Edition Bedford/St. Martins: Boston 2009.

Communication Strategies Essay

Technology is something we all use every day. It could be your cell phone, laptop, tablet, or anything else you prefer. Sadly to say, we also become dependent on these different types of technology. If you have dealt with technology enough in your lifetime, you know that it will fail you at some point in time. It is always at the most inconvenient times as well. Having an effective communication strategy to use while your technology or network isn’t available is very important. Should something happen to your network, you should have troubleshooting steps or a communication strategy readily available. It is the responsibility of the organization or business to make sure there is a communication strategy available. According to our text, an organization is a stable, formal social structure that takes resources them to produce outputs (Laudon & Laudon, 2012). The technical definition focuses on three elements of an organization. Capitol and labor are primary production factors provided by the environment (Laudon & Laudon, 2012). I’m not familiar with many organizations, so the organization that I am most familiar with is the military, the Air Force to be exact. Working in an office setting and also being a technical administrator, I constantly dealt with communication issues. When I think of a digital firm, I think of a firm in which nearly all of the organization’s significant business relationships with customers, suppliers, and employees are digitally enabled and mediated just like the text states (Laudon & Laudon, 2012). The internet is also the first thing that comes to my mind and I will be the first to admit that I use it for everything. I have become very dependent upon Google. I can think of millions of digital firms. Digital firms sense and respond to their environments far more rapidly than traditional firms; giving them more flexibility to survive in turbulent times (Laudon & Laudon, 2012). Digital firms place an emphasis on the digitization of business processes and services through sophisticated technology and information systems. Technology adoption has been increasing as digital firms continually look to achieve greater levels cost savings, competitive advantage, and operational performance optimization. The organization I choose to discuss is the United Services Automobile Association (USAA). It is a Fortune 500 financial services company offering banking, investing, and insurance to people and families that serve, or served, in the United States military. I became a member of this organization early 2009 and I do not ever see myself leaving this organization. I rate them five stars on their technology resources and systems. USAA uses technology in various areas within the organization to provide such a good â€Å"Customer Relationship Management† system. They provide to their customers online banking, mobile banking, the option to deposit checks from home, pay home or car insurance online, pay bills, submit insurance claims, and these are to just name a few. Whenever I call their 1-800 number, I rarely have to speak to a human unless I absolutely need to because almost everything is automated with them. Information systems or technology is very important in organizations today because more than 23 million managers and 113 million workers in the labor force rely on information systems to conduct business (Laudon & Laudon, 2012). That is a good deal of people. It is no wonder that Information Technology is such a growing career field with excellent salaries. Also, because of information systems, more people have the option to work from home. Information systems are essential for conducting day-to-day business in the United States and most other advanced countries, as well as achieving strategic business objectives (Laudon & Laudon, 2012). Doctor offices, retail stores, travel agencies, and many personal services use technology every day. Many business firms invest heavily in information systems to achieve six-strategic business objectives: products, services, and business models; customer and supplier intimacy; improved decision making; competitive advantage; and survival (Laudon & Laudon, 2012). Information systems are also the number one reason global marketing is so successful today. For example, many people choose to do online shopping during the holiday’s because it is less of a hassle, less stressful, and you can choose your own shopping hours. I have become a fan of online shopping as well because the sales are just as good as in-store sales. Internet service firms, such as Google, eBay, and Amazon, are able to replicate their business models and services in multiple countries without having to redesign their expensive fixed-cost information systems infrastructure (Laudon & Laudon, 2012). My personal favorite with USAA is their mobile banking. It is great having your banking information at the tip of your fingers. With so much identify theft and fraud in the world today, it is great to be able to see your account information in detail. If you look around, almost everyone owns a cell phone and most of them are smart phones. It is best to use these gadgets to their full capacity. I don’t always have time to stop by the bank or call to speak to a representative to have them make a transaction for me. I even have the option to schedule transactions’ so I will not have to remember to do it each day or month. It is more convenient to do it myself from my phone or computer versus doing it in person. I cannot recall the last time I actually paid any bills in person or mailed a payment in. I don’t think I will ever go back to that method if I can help it because I am all about saving time and making things simpler. As with everything, there are advantages and disadvantages and technology is no different. Although I feel that technology has made the population a bit lazier, we all have to admit it did make things in life a lot easier. I can recall being a technical administrator in the United States Air Force. Sadly to say, whenever we had power outages almost everything shut down. My fellow employees always thought that this meant go home for the rest of the day. Many times it did mean that. I tried not to fall victim to this because I am one of those people who feel like there is always work to be done. It was those times when I realized how heavily we depended on technology. I often wonder how advance technology will be 10 or 15 years from now and will everyone be able to keep up. I also worry about our senior citizens and I sympathize with them a great deal. My young nieces already know how to work computers, smart phones, you name it. Sometimes they teach me things about technology. While it made things simpler for the younger generation, it made things a lot more complex for our senior citizens. I often see my grandmother struggling to keep up with any assistance she may get because to renew or apply for it, she has to do it on the internet. Without any of my family’s assistance, she would never be able to do this. Most of our senior citizens are used to buying stamps and sending their mail off to the post office. Hopefully things don’t get too advanced for them. We must not leave them struggling to keep up. No matter what you’re viewpoint is on technology, we have to face the fact that it’s not going anywhere. References Haltiwanger, J., Lynch, L., & Mackie, C. (2007).

Adult Education and Training Essay

Abstract This paper work presents the summary of the most well known adult learning theory – Andragogy, explains how it accounts for the characteristics, patterns of learning, and motivation adopted by adult learners. Moreover, reflects on my own qualities and circumstance as an adult learner; critique the strengths and weaknesses of Andragogy. Key Words Andragogy, pedagogy, adult learning, education, training, adult learner, characteristics, motivation Introduction All these years, the specialized field of education has generated a number of models and theories of adult learning, included transformation learning theory, experiential learning theory, informal learning theory†¦etc. And the most important one with which to be familiar is Malcolm Knowles’ Andragogy. Andragogy was described as the â€Å"art and science to teaching adults to learn† (Knowles, Holton, & Swanson, 2005). It also interpreted the foundation and structure of adult learning, the concept of andragogy has been worldwide used in different times with different connotations and seem as a bible of adult education. Andragogy The notion of andragogy has been around for nearby two centuries. It originally formulated by a German teacher, Alexander Kapp, in 1833 (Nottingham Andragogy Group 1983). He used â€Å"andragogy† to describe education theory. Andragogy literally means â€Å"man leading†, which contrasted with pedagogy (Since andr- is Latin for â€Å"man†, peda is Latin for â€Å"child† and agogus is Latin for â€Å"leading†). And later on, couple educators had used the term of â€Å"andragogy† in their article. It included Rosenstock in 1921; Lindeman wrote â€Å"The Meaning of Adult Education† in 1926. The notion of â€Å"Andragogy† was well developed, widely discussed and used in 1980 by Malcolm Shepherd Knowles, a champion of andragogy. Knowles first introduced the concept of in the US in 1968. With his previous work on informal adult education, Knowles used those elements of process and setting to construct the shape and direction of adult e ducation. The concept he used to explain the theory of adult education was the notion of andragogy. â€Å"Malcolm Knowles, Informal adult education, self-direction and andragogy† (Jay-D Man, 2009). Knowles applied the idea of andragogy as the foundation of adult learning, he marked it as a new born technology which moderates the development and performance of adult learning. He posited six assumptions related to the adult learners: 1) Need to know, 2) self-concept, 3) experience, 4) readiness to learn, 5) orientation to learning , and 6) motivation to learn  (Knowles, 1980) Need to know â€Å"Adults want to know why they need to learn something before undertaking to learn it† (Knowles, 2005). Adults are realist, they want to find out what is the advantage and the loss before they make decision to do something. The â€Å"why†, â€Å"what†, â€Å"how†, â€Å"when†, â€Å"where† will first came to their mind before they making choices. For example: A man find he needs to improve his academy standard to get a promotion at work, which is â€Å"why† he wants to continue learning; he will choices a subject related to his present career to learn, he knows â€Å"what† he needs to learn and â€Å"what† is expected of him; in order to achieve his goal, he knows â€Å"how† he going to do and plan; beside works and take care his family, he needs to know â€Å"when† he studies; after conducts research, he knows â€Å"where† is a best place for his continuing learning. Self-Concept â€Å"Adults have a self-concept of being responsible for their own decisions, for their own lives† (Knowles, 1998). Adult learners are autonomous, they expect and enjoy independence, like to take control in everything and see themselves as self-directed. They don’t want adult educators use a pedagogical model to teach them. They think learning is a process of sharing with the teacher and one another, for example, they prefer interaction rather than formal subject issue. So teacher has responsibility to encourage and promote the process of self-direction. That is why Knowles emphasizes that adult educators must â€Å"make efforts to create learning experiences in which adults are helped to make the transition from dependent to self-directing learners† (Knowles, 1998). Experience For those adult learners, they are individual differences in their background, occupation, education standard, learning style, interests, goals and motivation will cause different experiences than youth when come into an educational activity (Knowles, 2005). Upon the adult learners’ prior experience, Knowles (1998) point out four paths that adult experience  learning: A wider range of individual differences will be established. Offer a richest resource for learning. Create deviation that can restrain, or sculpt new learning. Provide area for adults’ self-identity. Since the adult learners have many experiences, teacher must draw on learner experiences. Everyone in class could share their experiences through experiential techniques (simulations, group discussions, or problem-solving activities, etc). Moreover, sometime the adult learners may have more experience than the educator in some area. The communication and knowledge sharing will not only limit between instructor and student, also lead to 2 and 3 way interactions: between instructor and learner, learner and learner as well. Readiness to Learn Adults learn in order to cope effectively with real-life tasks. They normally come to class motivated, and ready to learn things they need to know. Knowles observes that â€Å"adults generally become ready to learn when their life situation creates a need to know† (Knowles, 2005). Anticipate the adults’ readiness to learn is very important in adult education, it determine how to proceed the training, and what strategies and activities should apply to meet a learner’s readiness. Surveys of learners prior to beginning a course, or some introduction course before the advanced courses are the ways to retrieve the material and aware the learner’s readiness. Orientation to learning Learning is a process of increasing competence to achieve full potential in life. According to Knowles, adults are problem-centered in their orientation to learning (Knowles, 2005). They prefer a problem solving orientation to learning (problem centered), rather than content-oriented. This orientation relates to their experience, task or problems in everyday situations. The sense of adults is that learning will allow them to execute task or deal with problems faced in life. When they confront real-life situation, they want to learn what will help them to contribute their  effectiveness, and they learn best in this status. Motivation Motivation is the last core of Andragogy assumption, but not the least. Knowles emphasizes the adult learner’s motivation can be blocked by training and education if neglect of adult learning principles (Knowles, 2005). â€Å"Adults tend to be more motivated toward learning that helps them solve problems in their livers or results in internal payoffs† (Knowles, 1998). Adult learners are responsive to some motivators. And normally those motivators can be divided into external (e.g., better job, higher salaries) and internal (e.g., desire of job satisfaction, self-esteem). And the andragogical model assumes adult learners tend to be more motived by the internal motivators than the external one. Implement Base on the six assumptions of Andragogy, let’s see how adult learners and educators began to implement the practical applications: Assumption Adult learner Educator Need to know Have a need to know what they expect to learn before investing time in a learning event Make sure that the learners know the aim, goal and purpose of training as early as they can. Self-concept Must uphold the concept of self-directing, responsible their own growing. Coach learners to find their needs and guide their own learning experience. Experience Come to a learning occasion with richest of experience and trade-off to contribute. Create and maintain a learning environment to build on and make use of learner’s experience. Readiness to learn Uphold a strong readiness to learn those things that they undertaking to learn. Ensure training relates directly to situations adult face in real-life task Orientation Dedicate their energy to learning things that help them cope with daily life  or solve a problem. Identify learner’s needs and interests, develop content based on the their needs. Motivation More responsive to internal motivators than external motivators. Create a safe learning environment and make sure the internal motivation will not blocked. Characteristics of Adult learners According to the Andragogy, Malcolm Knowles practiced a characterization of the defining features for adult learners, and shown as following: Adults have identifiable goal – they clearly understand what they need and know how to achieve their goal; Adults are independent – they are expect and enjoy independence, like to take control, and should allowed to express themselves freely; Adults have wealth of experience – need others to recognize their previous experience, including both positive and negative; Adults want immediate usefulness of their learning – they want to apply what they learn to solve and handle problems faced in their daily life; Adults fear to the educational process – normally graduated from school years and do not familiar with those process; Adults are hard to change – with their prior experience, their conducts become a habit, and some even though became their character already. Andragogy vs Pedagogy Since the Andragogy is a learning theory for adult learners, and which is contrast to Pedagogy. The following table summarizes the assumptions and processes of andragogy and pedagogy: Assumption / Processes Andragogy Pedagogy Need to know Clearly understand why they need to know before choose to learn. Only need to know what the teacher teaches. Self-concept Raise of self-directedness Dependency Experience Learners are a wealth resource for learning Tiny worth Readiness to learn Developed from life’s experience Directly related to age level and curriculum Orientation Problem centered Self centered Motivation Motivated by internal payoffs and curiosity Motivated by external incentives and punishment Time perspective Immediacy of application Postponed application Learning climate Interaction Respectful Informal Authority Competitive Formal Planning Mutual self-diagnosis By educator / instructor Formulation of objectives Mutual negotiation By educator / instructor Teaching strategies Experiential techniques Transmittal techniques Evaluation Mutual measurement of program By educator / instructor Barriers of learning Compare with children and teenagers, adult learners have different roles and many responsibilities in their daily life, they must balance against the demands of learning. Those responsibilities will cause barriers against their choice to return to school or participate in workplace training. Normally, those barriers can separated into three categories: 1) Attitudinal barriers; 2) Time and financial barriers; and 3) Education barriers. We need to identify those barriers and overcome them and take control of our own learning. Attitudinal barriers Knew already – People with â€Å"I already know† attitude to reject learning. He think it does not require training in that area, because he may already trained or thought himself had enough knowledge in that aspect. And properly people has this attitude are come with good education level; Previous experience – Generally people are used to learn in a traditional style, instructor teach with transmittal techniques. With this experience, they may feel the learning is irrelevant or boring, so they reject. Lacks of trust – Students attend a class with different backgrounds and goals. Do not trust the other participants will cause some of them do not participate actively in class for nervous and shy. Problems of motivation – people come to learn without initiative, they were forced to learn. Hard to motivate people if they don’t have own motivation. Time and financial barriers Lack of time – No matter the duration of a course, adults need to invest time to join it. They need to â€Å"sacrifice† from other activities and concern of its existence. Lack of money – Free training is minority. Therefore, money always is a main barrier to access adult education services. Family responsibilities – Caring for children, the obligation of accompany spouse, will cause shortage of study time. Organizing schedule – You need to change or sacrifice the study timetable because of the family and work responsibilities. Education barriers Too old to learn – Generally can be find in older and low education level people. The behaviour of reject learning is because they don’t familiar with the new technology or specialized languages, and their reaction time is often slow. Lack of confidence – Low self-esteem, past failures experience mark the adults, preventing them to overcome frustrations and fears. Reflection First of all, I would like to introduce myself, and the brief of my background are shown as below: Male, 42 years old, married with 2 children (12 Yrs & 7 Yrs). I’ve been serving the Hong Kong Police Force for 22 years, working in operational field but non-frontline. Besides operation planning, I’m also involved in a â€Å"Diploma in Police Search & Venue Security Programme†, which was held by Hong Kong Police and granted accreditation from HKCAAVQ, I’m one of the instructors of this programme. I am F.5 graduated, then granted a diploma of Police Policing on 2002, and that was my last academic certificate. According to my profile, I am a typical adult learner and faced most of the barriers that I had mentioned previously. I would like to critique the strengths and weaknesses of andragogy with my own circumstance. Strengths As an adult learner, the motivation of learning is very important, is core factor of adult education. Adults have different tasks and needs in their daily life; they will put their needs in orderly with the seniority. If the need is related to learning, they will have a great motivation, and learning become the priority in their life, so no any barriers can block them, and they study best in this situation. However, the concept of â€Å"motivation† is not the strength of andragogy in my view. Upon my opinion, I will choose the concept of â€Å"need to know†, because it’s the factor that cause â€Å"motivation†. With the â€Å"why†, â€Å"what† and â€Å"how†, I will explain the principle of â€Å"need to know† on my circumstance. At the beginning, I come to class for my own promotion and seem as career  investment. I like my current career, and seem to be my life occupation. In order to enhance my competitive advantage and help myself excel in my working place, I choose to continue learning. That will offer opportunities for further development and lead promotion. My view have change during this training, I find out I know more about the adult training theory, which help me to teach the trainee in my programme; enhance the communication skill with my children and people around me. The most important is I know myself more, I am shortage not only in academic standard but also in daily knowledge. I enjoy study and hunger for the knowledge. My motivation of learning becomes stronger and stronger, because I clearly understand why I need to learn, what I need to learn and how I need to learn. Weaknesses During this moment, I will say the concept of â€Å"Orientation† is the weakness of my own learning. Since I come for learning is not for a problem solve purpose, and the subject I study also not relate to my daily task. Conclusion Knowles introduced and develop the andragogy as core principles of adult learning. It help the educator designing and conducting adult learning, and build more effective learning processes for adults. Andragogy works prefect in practice when it is adapted to fit the special character of the learners and the learning organizations. References Adams, N. B. (n.d.). Andragogy. Andragogy.

The vessel was traveling outside normal shipping lanes in an attempt to avoid ice.Within six hours of the grounding, the Exxon Valdez spilled approximately 10. 9 million gallons of its 53 million gallon cargo of Prudhoe Bay crude oil. Eight of the eleven tanks on board were damaged. The oil would eventually impact over 1,100 miles of non-continuous coastline in Alaska, making the Exxon Valdez the largest oil spill to date in U. S. waters. The response to the Exxon Valdez involved more personnel and equipment over a longer period of time than did any other spill in U. S. history.Logistical problems in providing fuel, meals, berthing, response equipment, waste management and other resources were one of the largest challenges to response management. At the height of the response, more than 11,000 personnel, 1,400 vessels and 85 aircraft were involved in the cleanup. [pic] [pic] The Exxon Valdez aground on Bligh Reef. (Source: NOAA) Shoreline cleanup began in April of 1989 and continued until September of 1989 for the first year of the response. The response effort continued in 990 and 1991 with cleanup in the summer months, and limited shoreline monitoring in the winter months. Fate and effects monitoring by state and Fed eral agencies are ongoing. The images that the world saw on television and descriptions they heard on the radio that spring were of heavily oiled shorelines, dead and dying wildlife, and thousands of workers mobilized to clean beaches. These images reflected what many people felt was a severe environmental insult to a relatively pristine, ecologically important area that was home to many species of wildlife endangered elsewhere.In the weeks and months that followed, the oil spread over a wide area in Prince William Sound and beyond, resulting in an unprecedented response and cleanup—in fact, the largest oil spill cleanup ever mobilized. Many local, state, federal, and private agencies and groups took part in the effort. Even today, scientists continue to study the affected shorelines to understand how an ecosystem like Prince William Sound responds to, and recovers from, an incident like the Exxon Valdez oil spill. Events leading up to the spillThe Exxon Valdez departed from the Trans Alaska Pipeline terminal at 9:12 pm, March 23, 1989. William Murphy, an expert ship's pilot hired to maneuver the 986-foot vessel through the Valdez Narrows, was in control of the wheelhouse. At his side was the captain of the vessel, Joe Hazelwood. Helmsman Harry Claar was steering. After passing through Valdez Narrows, pilot Murphy left the vessel and Captain Hazelwood took over the wheelhouse. The Exxon Valdez encountered icebergs in the shipping lanes and Captain Hazelwood ordered Claar to take the Exxon Valdez out of the shipping lanes to go around the ice.He then handed over control of the wheelhouse to Third Mate Gregory Cousins with precise instructions to turn back into the shipping lanes when the tanker reached a certain point. At that time, Claar was replaced by Helmsman Robert Kagan. For reasons that remain unclear, Cousins and Kagan failed to make the turn back into the shipping lanes and the ship ran aground on Bligh Reef at 12:04 a. m. , March 24, 1989. Capt ain Hazelwood was in his quarters at the time.The National Transportation Safety Board investigated the accident and determined five probable causes of the grounding: (1) The third mate failed to properly maneuver the vessel, possibly due to fatigue and excessive workload; (2) the master failed to provide a proper navigation watch, possibly due to impairment from alcohol; (3) Exxon Shipping Company failed to supervise the master and provide a rested and sufficient crew for the Exxon Valdez; (4) the U. S. Coast Guard failed to provide an effective vessel traffic system; and (5) effective pilot and escort services were lacking.The behavior of the oil [pic] [pic] The oil slick (blue areas) eventually extended 470 miles southwest from Bligh Reef. The spill area eventually totaled 11,000 square miles. (Source: Exxon Valdez Oil Spill Trustee Council) Prudhoe Bay crude oil has an API gravity of 27. 0, and a pour point of 0 degrees Celcius. The bulk of the oil spilled from the Exxon Valdez was released within 6 hours of the ship's grounding. The general trend of the oil was south and west from the point of origin. For the first few days after the spill, most of the oil was in a large concentrated patch near Bligh Island.On March 26, a storm, which generated winds of over 70 mph in Prince William Sound, weathered much of the oil, changing it into mousse and tarballs, and distributed it over a large area. By March 30, the oil extended 90 miles from the spill site. Ultimately, from Bligh Reef, the spill stretched 470 miles southwest to the village of Chignik on the Alaska Peninsula. Approximately 1,300 miles of shoreline were oiled. 200 miles were heavily or moderately oiled (obvious impact); 1,100 miles were lightly or very lightly oiled (light sheen or occasional tarballs). The spill region contains more than 9,000 miles of shoreline.In addition to the storm of March 26, the spill occurred at a time of year when the spring tidal fluctuations were nearly 18 feet. This t ended to deposit the oil onto shorelines above the normal zone of wave action. The diversity in shoreline types in the affected areas led to varied oiling conditions. In some cases, oil was present on sheer rock faces making access and cleanup difficult, or rocky beaches with grain size anywhere from coarse sand to boulders, where the oil could percolate to a sub-surface level. The spill affected both sheltered and exposed (to high wave/weather action) shorelines.Once oil landed on a shoreline it could be floated off at the next high tide, carried to and deposited in a different location, making the tracking of oil migration and shoreline impact very difficult. This migration ended by mid-summer 1989, and the remaining cleanup dealt with oiled shorelines, rather than oil in the water. Cleanup operations continued during the summer months of 1990 and 1991. By 1990, surface oil, where it existed, had become significantly weathered. Sub-surface oil, on the other hand, was in many cases much less weathered and still in a liquid state. The liquid sub-surface oil could give off a sheen when disturbed.Cleanup in 1991 concentrated on the remaining reduced quantities of surface and sub-surface oil. Countermeasures and Mitigation Control of the oil spill at sea The Alyeska Pipeline Service Company was immediately notified of the incident and sent a tug to the site to assist in stabilizing the vessel. At the time of the incident, the Alyeska spill response barge was out of service being re-outfitted. It arrived on scene by 1500 on 24 March. Alyeska was overwhelmed by the magnitude of the incident; by March 25, Exxon had assumed full responsibility for the spill and cleanup effort. [pic] [pic] The Exxon Valdez surrounded by a containment boom. Source: Exxon Valdez Oil Spill Trustee Council) Deployment of boom around the vessel was complete within 35 hours of the grounding. Exxon conducted successful dispersant test applications on March 25 and 26 and was granted permissio n on March 26 to apply dispersants to the oil slick. Due to the large storm that began the evening of March 26, much of the oil turned into mousse. As dispersants aren't generally able to dissipate oil in the form of mousse, it was no longer practical to use dispersants on floating oil during this response. On the evening of March 25, a test in-situ burn of oil on water was conducted.Approximately 15,000 to 30,000 gallons of oil were collected using 3M Fire Boom towed behind two fishing vessels in a U-shaped configuration, and ignited. The oil burned for a total of 75 minutes and was reduced to approximately 300 gallons of residue that could be collected easily. It was estimated that the efficiency of this test burn was 98 percent or better. Again, continued in-situ burning was not possible because of the change in the oil's state after the storm of March 26. Five dispersant trials took place between March 25 and March 28, but by March 29 the Regional Response Team (RRT) decided tha t dispersants were no longer feasible.Because there was not enough equipment to protect all the shorelines that could be impacted, Federal, state and local agencies collaborated to establish shoreline protection priorities. The agencies decided that fish hatcheries and salmon streams had the highest priority; accordingly, containment booms were deployed to protect these areas. Five fish hatcheries in Prince William Sound and two in the Gulf of Alaska were boomed, with the largest amount of boom deployed at the Sawmill Bay hatchery in Prince William Sound.At the height of containment efforts, it is estimated that a total of 100 miles of boom was deployed. Almost all the types of boom available on the market were used and tested during the spill response. Due to the size of the spill, it was necessary to employ inexperienced workers to deploy and tend booms, and this led to some boom being incorrectly used or handled, and sometimes damaged. Some boom sank because of improper deploymen t, infrequent tending, or leakage and/or inadequacy in the buoyancy system. Other problems included fabric tears in boom due to debris, and tearing at anchorage points from wave action.In some cases, ballast chains were ripped off during boom recovery if the boom was lifted by the chain. One estimate suggests that 50 percent of the damage to larger boom came during boom recovery. For self-inflating booms, it was important to keep the inflation valves above the water during deployment so that the boom did not become filled with water and have to be replaced. Aerial surveillance was used to direct the deployment of booms and skimmers for open water oil recovery. Visual overflight observations as well as ultraviolet/infrared (UV/IR) surveys were used by the USCG and Exxon to track the floating oil.Satellite imagery was also tested as a method to track oil but was not very useful because of the infrequency of satellite passes over Prince William Sound (every 7 to 8 days), cloud cover, a nd lengthy turn around time for results. The primary means of open water oil recovery was with skimmers. In general, most skimmers became less effective once the oil had spread, emulsified and mixed with debris. To save time, it was most practical to keep skimmer offloading equipment and oil storage barges near the skimmers. The most used skimmers during the response were the Marco sorbent lifting-belt skimmers that were supplied by the U.S. Navy. Once oil became viscous, the sorbent part of the skimmer was removed and the conveyor belt alone was sufficient to pull the oil up the ramp. The pump that came with the skimmer had difficulty offloading viscous oil, so that other vacuum equipment was used to unload the collected oil. The Marco skimmers were generally not used close to shore because they draw between three and four feet. In general, the paddle belt and rope mop skimmers were the most useful for recovery of oil from the shoreline. The skimmers were placed on self-propelled b arges with a shallow draft.Sorbents were used to recover oil in cases where mechanical means were less practical. The drawback to sorbents was that they were labor intensive and generated additional solid waste. Sorbent boom was used to collect sheen between primary and secondary layers of offshore boom, and to collect sheen released from the beach during tidal flooding. Pompoms were useful for picking up small amounts of weathered oil. Towing of sorbent boom in a zigzag or circular fashion behind a boat was used to collect oil and was more efficient than towing the boom in a straight line.Sorbent booms made of rolled pads were more effective than booms made of individual particles because these absorbed less water and were stronger, and did not break into many small particles if they came apart. Early on in the response, storage space for recovered oil was in short supply. To combat the storage space problem, water was decanted from skimmers or tanks into a boomed area before offlo ading. As a result, the remaining viscous oil mixture was difficult to offload, the process sometimes taking up to 6 to 8 hours. High-capacity skimmer offloading pumps, in particular grain pumps, were the most useful in transferring viscous oil.The oil remaining on the Exxon Valdez, was completely offloaded by the end of the first week in April 1989. After offloading operations were completed, the tanker was towed to a location 25 miles from Naked Island in Prince William Sound for temporary repairs. Later in the summer of 1989, the vessel was brought to California for further repairs. Shoreline treatment Shoreline assessment was a prerequisite for the implementation of any beach cleanup. Assessment provided geomorphological, biological, archaeological and oiling information that was used for the development of site specific treatment strategies.Cleanup operations were scheduled around specific activities such as seal haulout activity, seal pupping, eagle nesting, fish spawning, fis hing seasons, and other significant events as much as possible. [pic] [pic] Shoreline treatment from the Exxon Valdez spill. (Source: Exxon Valdez Oil Spill Trustee Council) In 1989, hoses spraying seawater were used to flush oil from shorelines. The released oil was then trapped with offshore boom, and removed using skimmers, vacuum trucks (useful for thick layers of oil) and boom (sorbent, snare, pompoms).For hard to reach areas, or locations with weathered oil, heated seawater was used to flush oil from the shoreline. Converted vessels and barges were used for beach washing operations. It would take several days to outfit a conventional barge with the equipment needed to heat and pump the water. Smaller vessels that were used for beach washing early in the spill were re-outfitted for bioremediation later in the response. Along with the large-scale beach washing, manual cleanup, raking and tilling the beaches, oily debris pickup, enhanced bioremediation and spot washing were used to cleanup the oil.In some locations, oil was thick enough to be picked up with shovels and buckets. In addition, mechanical methods were used on a few sites, including the use of bulldozers to relocate or remove the contaminated beach surfaces. Mechanical rock washing machines, which were manufactured for the spill, were not used to clean contaminated rocks and return them to the beach. Oiled storm berm was mechanically relocated in some cases so that these areas, which normally would not receive much wave action, would be more exposed and cleaned by natural processes.If the oiling in the berm was significant or persistent it was tilled to free the oil or washed to optimize the cleaning. Recommendations were made to restrict the movement of berm to the upper third of the beach to ensure its return to the original location. [pic] [pic] Beach washing. (Source: Exxon Valdez Oil Spill Trustee Council) Beach applications of dispersants were tried in several locations. Corexit 7664 was a pplied on Ingot Island, followed by a warm water wash. No significant change in oil cover or the physical state of the oil was observed as a result of the treatment. Some ecological impacts were observed in the treated areas.It appeared that the effects were largely due to the intensive washing more than to the use of Corexit 7664, and were evident in intertidal epibenthic macrobiota. In addition, the dispersant BP1100X was applied to a test area on Knight Island. Toxicology studies indicated that the upper and lower intertidal biota were different from pre-application communities the day after dispersant application, and returned to pre-treatment levels after seven days. In May of 1989, the U. S. Environmental Protection Agency (EPA) and Exxon conducted bioremediation trials at two test sites on Knight Island in Prince William Sound.On the basis of these tests and other trials later in the summer, Exxon recommended the use of the bioremediation enhancement agents, Inipol (Inipol EA P22—manufactured by Elf Aquitaine of France) and Customblen (Customblen 28-8-0 —manufactured by Sierra Chemicals of California), and subsequently treated over 70 miles of shoreline in Prince William Sound with these agents. Winter monitoring of the effects of bioremediation consisted of surveys of more than 20 beaches in Prince William Sound and the Gulf of Alaska.These studies determined that oil degradation had been enhanced on the shorelines monitored, but some debate existed over whether bioremediation was solely, or even largely, responsible. Cleanup operations in 1989 ceased by the end of September. All parties involved in the response agreed that continuation of cleanup into the Alaskan winter would jeopardize the safety of cleanup crews. In addition, it was speculated that the winter storms in Alaska could significantly remove oil from shorelines, including sub-surface oil.By the end of the 1989 cleanup, more than 25,000 tons of oiled waste and several hundred thousand barrels of oil/liquid waste were collected and disposed of in landfills. Cleanup in 1990 began in April and ended in September. Surveys in the spring of 1990 showed that oiling conditions had been reduced or changed over the winter. Surface oil in 1990 was significantly weathered but sub-surface oil was relatively fresh in some locations. Cleanup techniques in 1990 focused more on manual methods of treatment such as hand wiping and spot washing as well as bioremediation.Mechanical equipment was used on a few sites. Bioremediation was more extensive in 1990, with 378 of the 587 shoreline segments treated that year receiving bioremediation application. In general, Inipol was applied in cases where surface oiling existed and Customblen slow release pellets were preferred for treating beaches with sub-surface oiling. Generally, beaches were given one to three treatments over several months. Concern over the possible toxicity of Inipol led to recommendations for application of o nly Customblen on some sites.By the spring of 1991, the scope of the cleanup effort was greatly reduced. Manual cleanup, bioremediation, and very limited use of mechanical equipment were employed. Cleanup took place from May of 1991 through July of 1991. An important observation that resulted from the Exxon Valdez oil spill was that natural cleaning processes, on both sheltered and exposed beaches, were in many cases very effective at degrading oil. It took longer for some sections of shoreline to recover from some of the invasive cleaning methods (hot water flushing in particular) than from the oiling itself.Economic impacts The State of Alaska funded a several studies of the short term economic impact of the Exxon Valdez oil spill. [pic] [pic] Recreational fishing in Alaska. (Source: Exxon Valdez Oil Spill Trustee Council) 1. Recreational Sport Fishing Losses. This loss was estimated based on the impacts of the spill on sport fishing activity. One must consider the impact on the n umber of anglers, the number of sport fishing trips, the areas fished, the species fished for, and the length of these trips.For 1989 the loss was estimated to be between $0 and $580 million dollars; for 1990 the range was $3. 6 million $50. 5 million dollars. 2. Tourism Losses. The spill caused both negative and positive effects. The major negative effects were: 1. Decreased resident and non-resident vacation/pleasure visitor traffic in the spill-affected areas due to lack of available visitor services (accommodations, charter boats, air taxis). 2. Severe labor shortage in the visitor industry throughout the state due to traditional service industry workers seeking high-paying spill clean-up jobs. 3.Fifty-nine percent of businesses in the most affected areas reported spill-related cancellations and 16% reported business was less than expected due to the spill. The principle positive impact was strong spill-related business in some areas and in certain businesses such as hotels, tax is, car/RV rentals and boat charters. 1. Existence value. Economists tried to estimate the damage to so-called non-use or existence value of the Prince William Sound region in the wake of the spill. This is an attempt top measure what cannot be observed in the market: the value to the public of a pristine Prince William Sound.They estimated existence value using contingent valuation, a survey approach designed to create the missing market for public goods by determining what people would be willing to pay (WTP) for specified changes in the quantity or quality of such goods or, more rarely, what they would be willing to accept (WTA) in compensation for well-specified degradations in the provision of these goods. The results suggest an aggrragete loss of $4. 9 to $7. 2 billion dollars. In effect, these amounts reflect the public's willingness to pay to prevent another Exxon Valdez type oil spill given the scenario posed. . Replacement costs of birds and mammals. These costs include th e relocation, replacement and rehabilitation for some of the shorebirds, seabirds and the marine and terrestrial mammals that may have suffered injury or were destroyed in the Exxon Valdez oil spill. The values range from $20,000 to $300,000 dollars per marine mammal (sea otters, whales, seal lions, seals), $125 to $500 dollars per terrestrial animal (bears, river otters, mink, deer), and $170 to $6,000 dollars for seabirds and eagles. How much oil remains?Based on the areas that were studied in the aftermath of the spill, scientists made estimates of the ultimate fate of the oil. A 2001 National Oceanic and Atmospheric Administration (NOAA) study surveyed 96 sites along 8,000 miles of coastline. [pic] [pic] A pit dug on a Prince William Sound beach in 2001 revealing oil in the sediments. (Source: NOAA) The survey distinguished between surface and buried oil. Buried or subsurface oil is of greater concern than surface oil. Subsurface oil can remain dormant for many years before bein g dispersed and is more liquid, still toxic, and may become biologically available.A disturbance event such as burrowing animals or a severe storm reworks the beach and can reintroduce unweathered oil into the water. Results of the summer shoreline survey showed that the oil remaining on the surface of beaches in Prince William Sound is weathered and mostly hardened into an asphalt-like layer. The toxic components of this type of surface oil are not as readily available to biota, although some softer forms do cause sheens in tide pools. The survey indicates a total area of approximately 20 acres of shoreline in Prince William Sound are still contaminated with oil.Oil was found at 58 percent of the 91 sites assessed and is estimated to have the linear equivalent of 5. 8 km of contaminated shoreline. In addition to the estimated area of remaining oiled beach, several other important points were evident: 1. Surface oil was determined to be not a good indicator of subsurface oil. 2. Twe nty subsurface pits were classified as heavily oiled. Oil saturated all of the interstitial spaces and was extremely repugnant. These â€Å"worst case† pits exhibited an oil mixture that resembled oil encountered in 1989 a few weeks after the spill—highly odiferous, lightly weathered, and very fluid. 3.Subsurface oil was also found at a lower tide height than expected (between 0 and 6 feet), in contrast to the surface oil, which was found mostly at the highest levels of the beach. This is significant, because the pits with the most oil were found low in the intertidal zone, closest to the zone of biological production, and indicate that the survey estimates are conservative at best. Ecosystem response to the spill Recovery is a very difficult term to define and measure for a complex ecosystem such as Prince William Sound. If you ask a fisherman from Kodiak Island, a villager from the town of Valdez, an Exxon engineer, or a NOAA iologist, you are likely to receive such different answers that you may wonder if they heard the same question. In particular, disagreements exist between Exxon and government-funded scientists, and unknowns persist, especially in understanding how multiple processes combine to drive observed dynamics. Despite this, there are some things known with a high degree of certainty: oil persisted beyond a decade in surprising amounts and in toxic forms, was sufficiently bioavailable to induce chronic biological exposures, and had long-term impacts at the population level.Three major pathways of long-term impacts emerge: (1) chronic persistence of oil, biological exposures, and population impacts to species closely associated with shallow sediments; (2) delayed population impacts of sublethal doses compromising health, growth, and reproduction; and (3) indirect effects of trophic and interaction cascades, all of which transmit impacts well beyond the acute-phase mortality. Acute Mortality [pic] [pic] Sea birds killed by the Exxon Valdez oil spill. (Source: NOAA) Marine mammals and seabirds are at great risk from floating oil because they have routine contact with the sea surface.Oiling of fur or feathers causes loss of insulating capacity and can lead to death from hypothermia, smothering, drowning, and ingestion of toxic hydrocabons. Scientists estimate mass mortalities of 1000 to 2800 sea otters, 302 harbor seals, and unprecedented numbers of seabird deaths estimated at 250,000 in the days immediately after the oil spill. Mass mortality also occurred among macroalgae and benthic invertebrates on oiled shores from a combination of chemical toxicity, smothering, and physical displacement from the habitat by pressurized wash-water applied after the spill.Long-term impacts The persistent nature of oil in sediments produce chronic, long-term exposure risks from some species. For example, chronic exposures for years after the spill to oil persisting in sedimentary refuges were evident from biomarkers in fish, se a otters, and seaducks intimately associated with sediments for egg laying or foraging. These chronic exposures enhanced mortality for years. Indirect effects can be as important as direct exposure.Cascading indirect effects are delayed in operation because they are mediated through changes in an intermediary. Perhaps the two generally most influential types of indirect interactions are: (1) trophic cascades in which predators reduce abundance of their prey, which in turn releases the prey’s food species from control; and (2) provision of biogenic habitat by organisms that serve as or create important physical structure in the environment. [pic] [pic] A healthy stand of rockweed (Fucus gardneri) growing on a boulder in Prince William Sound. Source: NOAA) Scientists have found that indirect interactions lengthened the recovery process on rocky shorelines for a decade or more. Dramatic initial loss of cover by the most important biogenic habitat provider, the rockweed Fucus gar dneri, triggered a cascade of indirect impacts. Freeing of space on the rocks and the losses of important grazing (limpets and periwinkles) and predatory (whelks) gastropods combined to promote initial blooms of ephemeral green algae in 1989 and 1990 and an opportunistic barnacle, Chthamalus dalli, in 1991.Absence of structural algal canopy led to declines in associated invertebrates and inhibited recovery of Fucus itself, whose recruits avoid desiccation under the protective cover of the adult plants. Those Fucus plants that subsequently settled on tests of Chthamalus dalli became dislodged during storms because of the structural instability of the attachment of this opportunistic barnacle. After apparent recovery of Fucus, previously oiled shores exhibited another mass rockweed mortality in 1994, a cyclic instability probably caused by simultaneous senility of a single-aged stand.The importance of indirect interactions in rocky shore communities is well established, and the genera l sequence of succession on rocky intertidal shores extending over a decade after the Exxon Valdez oil spill closely resembles the dynamics after the Torrey Canyon oil spill in the UK. State of recovery The Exxon Valdez Oil Spill Trustee Council published a study in 2004 to assess the state of the resources injured by the spill. Fifteen years after the Exxon Valdez oil spill, it is clear that some fish and wildlife species injured by the spill have not fully recovered.It is less clear, however, what role oil plays in the inability of some populations to bounce back. An ecosystem is dynamic — ever changing — and continues its natural cycles and fluctuations at the same time that it struggles with the impacts of spilled oil. As time passes, separating natural change from oil-spill impacts becomes more and more difficult. The Trustee Council recognizes 30 resources or species as injured by the spill. Depending on their status as of 2002, these have been placed in one of f ive categories: Not RecoveringThese resources are showing little or no clear improvement since spill injuries occurred: Common loon Cormorants (3 species), Harbor seal, Harlequin duck, Pacific herring, Pigeon guillemot Recovery unknown Limited data on life history or extent of injury is available. Current research is either inconclusive or not complete: Cutthroat trout, Dolly Varden, Kittlitz’s murrelet, Rockfish Subtidal communities [pic] [pic] Sockeye salmon (Oncorhynchus nerka). (Source: NOAA) Recovered Recovery objectives have been met: Archaeological resources, Bald eagle, Black oystercatcher, Common murre, Pink salmon, River otter, Sockeye salmon RecoveringClams, Wilderness Areas, Intertidal communities, Killer whale (AB pod), Marbled murrelet, Mussels, Sea otter, Sediments Human uses Human services that depend on natural resources were also injured by the spill. These services are each categorized as â€Å"recovering† until the resources they depend on are fully recovered: Commercial fishing, Passive use, Recreation and tourism, Subsistence Prior to the Exxon Valdez oil spill, there was no baseline date available for the abundant number of species existing in Prince William Sound.Because of this lack of data, numbers of oil spill-related casualties and recovery rates have been difficult to determine. Legal responsibility of ExxonMobil The settlement among the State of Alaska, the U. S. government and Exxon was approved by the U. S. District Court on Oct. 9, 1991. It resolved various criminal charges against Exxon as well as civil claims brought by the federal and state governments for recovery of natural resource damages resulting from the oil spill.The settlement was comprised of criminal and civil settlements with Exxon, as well as a civil settlement with Alyeska Pipeline Service Company. Criminal Settlement Plea Agreement Exxon was fined $150 million, the largest fine ever imposed for an environmental crime. The court forgave $125 milli on of that fine in recognition of Exxon's cooperation in cleaning up the spill and paying certain private claims. Of the remaining $25 million, $12 million went to the North American Wetlands Conservation Fund and $13 million went to the national Victims of Crime Fund.Criminal Restitution As restitution for the injuries caused to the fish, wildlife, and lands of the spill region, Exxon agreed to pay $100 million. This money was divided evenly between the federal and state governments. Civil Settlement Exxon agreed to pay $900 million in ten annual installments. The final payment was received in Sept. 2001. The settlement contains a â€Å"reopener window† between Sept. 1, 2002 and Sept. 1, 2006, during which the state and federal governments may make a claim for up to an additional $100 million.The funds must be used to restore resources that suffered a substantial loss or decline as a result of the oil spill, the injuries to which could not have been known or anticipated by t he six trustees from any information in their possession or reasonably available to any of them at the time of the settlement (Sept. 25, 1991). The response of ExxonMobil [pic] [pic] Exxon logo. ExxonMobil acknowledged that the Exxon Valdez oil spill was a tragic accident that the company deeply regrets. Exxon notes that company took immediate responsibility for the spill, cleaned it up, and voluntarily compensated those who claimed direct damages.ExxonMobil paid $300 million immediately and voluntarily to more than 11,000 Alaskans and businesses affected by the Valdez spill. In addition, the company paid $2. 2 billion on the cleanup of Prince William Sound, staying with the cleanup from 1989 to 1992, when the State of Alaska and the U. S. Coast Guard declared the cleanup complete. And, as noted above, ExxonMobil also has paid $1 billion in settlements with the state and federal governments. That money is being used for environmental studies and conservation programs for Prince Will iam Sound.ExxonMobil hired its own scientists to study the impacts of the spill, and they come to different conclusions than many of the results published by government agencies and peer-reviewed academic journals. Exxon's scientists acknowledge the lingering pockets of oil in the sediments, but they argue that they do not pose a serious risk. It is their position that that there are now no species in Prince William Sound in trouble due to the impact of the 1989 oil spill, and that the data strongly support the position of a fully recovered Prince William Sound ecosystem.Lessons learned from the spill The scientists who monitored the oiled parts of Prince William Sound wanted to study the shoreline’s ecological recovery after an environmental disaster like the Exxon Valdez spill, and then use those lessons to better respond to future oil spills. Right now, their task is still incomplete. However, some of their findings have changed the way they think about cleaning up oil spi lls, and about how ecosystems respond to such disturbances. Following are some examples of what they have learned: 1.Clean-up attempts can be more damaging than the oil itself, with impacts recurring as long as clean-up (including both chemical and physical methods) continues. Because of the pervasiveness of strong biological interactions in rocky intertidal and kelp forest communities, cascades of delayed, indirect impacts (especially of trophic cascades and biogenic habitat loss) expand the scope of injury well beyond the initial direct losses and thereby also delay recoveries. 2.Oil that penetrates deeply into beaches can remain relatively fresh for years and can later come back to the surface and affect nearby animals. In addition, oil degrades at varying rates depending on environment, with subsurface sediments physically protected from disturbance, oxygenation, and photolysis retaining contamination by only partially weathered oil for years. 3. Rocky rubble shores should be of high priority for protection and cleanup because oil tends to penetrate deep and weather very slowly in these habitats, prolonging the harmful effects of the oil when it leaches out. . Oil effects to sea birds and mammals also are substantial (independent of means of insulation) over the long-term through interactions between natural environmental stressors and compromised health of exposed animals, through chronic toxic exposure from ingesting contaminated prey or during foraging around persistent sedimentary pools of oil, and through disruption of vital social functions (caregiving or reproduction) in socially organized species. 5.Long-term exposure of fish embryos to weathered oil at parts per billion (ppb) concentrations has population consequences through indirect effects on growth, deformities, and behavior with long-term consequences on mortality and reproduction. The Exxon Valdez also triggered major improvements in oil spill prevention and response planning. 1. The U. S. C oast Guard now monitors fully-laden tankers via satellite as they pass through Valdez Narrows, cruise by Bligh Island, and exit Prince William Sound at Hinchinbrook Entrance. In 1989, the Coast Guard watched the tankers only through Valdez Narrows and Valdez Arm. . Two escort vessels accompany each tanker while passing through the entire Sound. They not only watch over the tankers, but are capable of assisting them in the event of an emergency, such as a loss of power or loss of rudder control. Fifteen years ago, there was only one escort vessel through Valdez Narrows. 3. Specially trained marine pilots, with considerable experience in Prince William Sound, board tankers from their new pilot station at Bligh Reef and are aboard the ship for 25 miles out of the 70-mile transit through the Sound.Weather criteria for safe navigation are firmly established. 4. Congress enacted legislation requiring that all tankers in Prince William Sound be double-hulled by the year 2015. It is estimat ed that if the Exxon Valdez had had a double-hull structure, the amount of the spill would have been reduced by more than half. There are presently three double-hulled and twelve double-bottomed tankers moving oil through Prince William Sound. Two more Endeavor class tankers are under construction by ConocoPhillips, their expected induction into service is 2004 and 2005. . Contingency planning for oil spills in Prince William Sound must now include a scenario for a spill of 12. 6 million gallons. Drills are held in the Sound each year. 6. The combined ability of skimming systems to remove oil from the water is now 10 times greater than it was in 1989, with equipment in place capable of recovering over 300,000 barrels of oil in 72 hours. 7. Even if oil could have been skimmed up in 1989, there was no place to put the oil-water mix. Today, seven barges are available with a capacity to hold 818,000 barrels of recovered oil. . There are now 40 miles of containment boom in Prince William Sound, seven times the amount available at the time of the Exxon Valdez spill. 9. Dispersants are now stockpiled for use and systems are in place to apply them from helicopters, airplanes, and boats. Further Reading †¢ Alaska Fisheries Science Center, NOAA.
