Biological Differences that Exist Between Individuals in a Population E

Biological Differences that Exist Between Individuals in a Population Physical anthropologists view humans as biological organisms. Coupled with genetics and biochemistry, scientists can form a more complete picture of human anatomy, both past and present. Physical anthropology looks at human variation and evolution. Variation looks at the biological differences that exist between individuals within a population and at individuals between populations (e.g., body shape, size, and physiological responses). These differences in human biology are measured using a technique called anthropometry 1. In order to explain this diversity, physical anthropologists look to environmental conditions (including culture) and genetics. Taking these factors into account, the anthropologist attempts to formulate an evolutionary explanation for the differences. Human evolution looks at the bodily changes that have occurred over the years leading up to modern day Homo sapiens. In order to determine the changes that have taken place in human anatomy we rely on paleoanthropology, the study of human fossil remains, and primatology, and the study of other primates 1. Paleoanthropology helps us determine who our ancestors were, and when, how and why they evolved. Primatology allows us to see the similarities and differences between other primates and ourselves and allows us to trace these evolutionary relationships. For example, such a study has determined that humans share approximately 98.6% of their DNA (their genetic code) with gorillas, 98.8% with chimpanzees and 97.6% with orangutans 2. Approaching human variation from the perspective of the anthropologist leaves a vast field of study before the world of medicine. One of the most fascinating examples of human variation is the found in albinism. The word "albinism" refers to a group of genetically inherited conditions. People with albinism have little or no pigment in the eyes, skin, and hair (or in some cases in the eyes alone). They have inherited from their parents an altered copy of genes that does not work correctly. The altered gene does not allow the body to make the usual amounts of a pigment called melanin. Approximately one in 17,000 people have one of the types of albinism. About 18,000 people in the United States are affected 3. Albinism affects people from all races.

A Futile Task- the Catcher in the Rye Essay

The teenager stands on a hill in complete solitude, watching the nearby football game, and contemplating if he should say a final farewell to the school. Ambivalent, the melancholy teenager leaves himself in a confused and vulnerable position to the lonely and corrupt reality of the world. In an attempt to endure the vices that alter the blissful spirit, he feels the need to make things right by saving what little recognizable evidence of purity that the world has not already desecrated. All throughout the novel The Catcher in the Rye, author J. D. Salinger establishes Holden’s bizarre attraction toward particular places, objects, and experiences, past and present. The author concurrently sets out the subtle, tender concern that Holden has for the preservation of innocence and where life will ultimately end up. At essential points in the plot, Salinger embodies these two motifs, which metaphorically represent each other, in order to uncover the true sadness that lurks in an abandoned Holden. By doing this, the author reveals the greater theme that unlike artifacts of history, constrained the human spirit would severely stunt any opportunity of development for people. Salinger constantly highlights the motif of Holden’s endeavors to preserve innocence from being tainted by corruption. The author first presents this through the objects that Holden develops a bond with. To demonstrate that bond, Salinger produces a scene in which Holden visits his old teacher, Mr. Spencer, one of the few concerned about the boy. The teacher asks Holden to read his paper about Egyptian mummifying aloud. Salinger first demonstrates Holden’s obsession for the preservation of life when Holden divulges that â€Å"Modern science would still like to know what the secret ingredients were that the Egyptians used when they wrapped up dead people so that their faces would not rot for innumerable centuries† (Salinger 16). Implying the deep interest that Holden possesses for this subject, Salinger underscores that the teenager may have experienced a harrowing event relating to the matter. Because Holden would still dearly like to know the â€Å"secret† of maintaining life in such a state, the author also exposes Holden’s unawareness of the topic altogether. Leaving Holden in an unaware state, the author then inserts the minor motif of Holden’s younger brother’s baseball mitt to clear the confusion. When asked to write a composition for a classmate, of all the topics Holden decides to write about, the nostalgic adolescent distinguishes his younger brother’s baseball mitt. With this sacred object, Salinger links it to Holden’s goal for conserving the unharmed and the aesthetic, as the glove had poems scribed all over it in ink. The author represents the ink as the permanence in which the item endures. Similar to the beloved baseball mitt, Holden finds solidity in a Little Shirley Beans record that he purchases. Identifying the song eternally preserved on the record, the writer elucidates that Holden still preserves things in the state that they are left, never allowing them to change. Salinger also represents Holden’s remembrance of the innocence of childhood, the record reminding him of that period. In addition to the revered objects, the author exhibits a pattern in Holden’s experiences and anecdotes that motivate Holden in the direction of making events like those last for an eternity. One of Holden’s recollections that Salinger touches on briefly involves Holden playing checkers with a childhood friend, Jane Gallagher. At one point in the game, Jane cries, and sensing this, Holden drives his efforts to console with her, kissing her all over her face, avoiding her mouth. Symbolizing the need to protect Jane and her virginity, the author portrays Holden comforting her instead of violating her, revealing the tender empathy that Holden possesses. Prior to reflecting this memory, Holden underwent an instance of rejection at a bar, and seeing what little empathy people have, Holden tries to remember a positive memory to keep his motivation alive. One of Holden’s fondest memories stems from the remembrance of his younger brother. When given time to ruminate upon his past, Allie stands out as the ideal brother that Holden would never find in any other person. Salinger distinguishes Allie as â€Å"terrifically intelligent† and that â€Å"he was also the nicest†¦ he never got mad at anybody. People with red hair are supposed to get mad very easily, but Allie never did, and he had very red hair† (Salinger 50). Portraying Allie as the epitome of childhood innocence, the author juxtaposes this to Holden’s thoughts of preserving purity. Because his sibling passed away at an extremely young age, Holden’s sole coping strategy involves the thought of bringing back his brother, thinking that someone as magnanimous as Allie deserves to live on. Despite Holden’s naive point of view toward what troubles him, he finally begins to subtly realize something about his brother. Salinger weaves a scene of Holden conversing with Phoebe, his younger sister, and the teenager mentions that he loves Allie, thinking that he still exists. Following Phoebe’s comment that Allie is dead, Holden refuses to accept and reveals that â€Å"Just because somebody’s dead, you don’t just stop liking them, for God’s sake—especially if they were about a thousand times nicer than the people you know that’re alive an all† (Salinger 223). Salinger highlights a rare moment: someone offering guidance to Holden, accepting that he is stuck. By displaying Holden touching upon Allie, Salinger expresses the adolescent beginning to address the connection with Allie. However, Holden still possesses the unawareness to come to terms with this. Salinger effectively amplifies the essence of Holden’s being in a thought of the teenager. The author illustrates a dream of Holden desiring to catch children who accidentally fall off the ledge of a cliff in the rye field, the adolescent defining himself as a catcher in the rye. The author resembles Holden as a selfless martyr in this thought, leaving Holden in bliss that he can save people if they fall; the author makes clear that, for Holden, danger should be avoided by all means and at all costs. Salinger stems the implication from Holden’s own dealings with losses Perhaps the most important category that Holden associates with conservation and longing consists of the places that he visits. One of the first locations that Salinger introduces pertains to the museum, a site of never changing exhibits. The boy favors that all the displays stay the way they are and that things are kept in fixed positions. By symbolizing the museum as a place where nothing changes, Salinger mirrors the setting to Holden’s opposition to growing up and change. Salinger initiates the beginning of a epiphany for Holden when the teenager travels to his old elementary school to meet with Phoebe. The writer describes the school as familiar to Holden While appearing to give up hope on the world, Holden sees yet another instance of chicanery. The author depicts an obscenity on the wall that appalls Holden, and in the act he makes of rubbing it out, Salinger reiterates Holden as a savior figure and that combating all of evil can be accomplished. The author furthers the learning experience for Holden when the teenager returns to the museum. Although feeling tranquil while all alone in one of the showcases, Holden observes yet another contemptible obscenity, defacing one of the glass cases. By repeating the obscenity for Holden, Salinger starts to affirm in Holden that he cannot keep everything clean and pure but must accept events like these once in a while. Finally pivoting Holden’s vague realization to the last crucial place, Salinger fleshes out the epiphany. Accompanied by phoebe, Holden views one of the carousels nearby, his attraction to it brought on by the fact that the ride always plays the same song. Holden again clings to a familiar tangent and what comforts him. Yet, the teenager watches Phoebe go around on the carousel and sees her and other children trying to grab for the gold ring. Salinger depicts Holden as â€Å"afraid that she’d fall off† but he does not react, as Holden realizes that â€Å"If they fall off, they fall off, but it’s bad if you say anything to them† (Salinger 274). Paralleling and directing opportunity and danger close together, Salinger enables acceptance in Holden that if people stay the same way, there leaves no room for development, thus rendering them static, strayed from the dynamics of change, and this time, Holden does not deny Phoebe or himself the opportunity to mature.

Similarly, the continuation of old-growth logging in Tasmania may reduce opportunities for nonextractive economic opportunities such as ecotourism. In a political and economic environment where governments currently see themselves as highly dependent on the short term revenues from natural resource extraction industries, the needs of the tourism industry may be seen as secondary.

Vomiting

Your body has a few main ways to respond to an ever-changing, wide variety of invaders and irritants. Sneezing ejects the intruders from the nose, coughing from the lungs and throat, diarrhea from the intestines, and vomiting from the stomach. Vomiting is a forceful action accomplished by a fierce, downward contraction of the diaphragm muscle. At the same time, the abdominal muscles tighten against a relaxed stomach with an open gastroesophageal sphincter. The contents of the stomach are propelled up and out. As part of a bodily reflex, you may produce more saliva just before vomiting. Vomiting is a complex, coordinated reflex orchestrated by the vomiting center of the brain. It responds to signals coming from: †¢The mouth, stomach, and intestines †¢The bloodstream, which may contain medicines or infections †¢The balancing systems in the ear (motion sickness) †¢The brain itself, including unsettling sights, smells, or thoughts An amazing variety of stimuli can trigger vomiting, from migraines to kidney stones. Sometimes, just seeing someone else vomit will start you vomiting, in your body's effort to protect you from possible exposure to the same danger. Vomiting is common. Almost all children will vomit several times during their childhood. In most cases, it is due to a viral gastrointestinal infection. Spitting up, the gentle sloshing of stomach contents up and out of the mouth, sometimes with a burp, is an entirely different process. Some spitting up is normal for babies, and usually gets gradually better over time. If spitting up worsens or is more frequent, it might be reflux disease. Discuss this with your child's doctor. Most of the time, nausea and vomiting do not require urgent medical attention. However, if the symptoms continue for days, they are severe, or you cannot keep down any food or fluids, you may have a more serious condition. Dehydration is the main concern with most vomiting. How fast you become dehydrated depends on your size, frequency of vomiting, and whether you also have diarrhea.

The Theories Of Language Acquisition Essay Example | Topics and Well Written Essays - 2500 words

The Theories Of Language Acquisition - Essay Example This paper will review theories of language acquisition and their relationship to the academic outcomes of 16 students enrolled in a childcare course. First, popular theories of language acquisition will be presented. Secondly, the process of langue development in a child will be outlined, whilst emphasizing developmental stages that vocab, syntax, and pragmatics occur. Finally, an indication of learning developments at secondary school and at higher education will be discussed, particularly in regard to students undertaking a childcare course. I would like to remind the reader of Clibbens warning of not to be caught up in the various debates which can deviate from the true purpose of helping all children, young people and adults to use language and communicate. It is generally accepted that language acquisition is partly innate and partly environmental (Bickerton, 1990). It is generally conceded that for all people, language development is a gradual process that occurs through general development and interaction with people and the environment.Nurture Skinner Skinner's (1957) behavioral approach to language acquisition was simply a set of habits. He did not consider language to be different to any other behavior. The learner of a language is a tabular rosa - an empty slate. He ignored nativist approaches of innate knowledge, as the inner workings of language were unobservable and so un-measurable. Skinner insisted that interaction with the environment leads to stimulus-response conditioning and that the product of this is knowledge. For example, an unconditional environment brings about an unconditional response, the response is followed by an event that is to the liking of the learning organism, and the response becomes positively reinforced. If this sequence of events occurs a number of times, the organism learns to associate the response to the stimulus to the reinforcement. So that when encountering the stimulus again, the same response will be elicited, and so becomes a conditioned response. Behaviorism considers that all learning, including language, occurs through this process of establishing habits. Hence, a linguistic input is due to linguistic utterances in one's environment as stimulus. However, it has been noted in research since that imitation alone does not allow for language acquisition, and simplistic stimulus-response conditionings do not account for it either (Kiyamazarslan, 2001).Piaget Piaget (1952) was a biologist and a psychologist and yet he felt that language acquisition was due to social interaction (cited in Kiymazarslan, 2001). He saw a child's language ability as being reflected in their ability to manipulate symbols, and that a child learns when they are developmentally ready to.

Sport, Fitness and Management Coursework Example | Topics and Well Written Essays - 1000 words

Sport, Fitness and Management - Coursework Example I have also been involved in the planning and preparing of coaching sessions and coaching children at FA Learning in Liverpool County. I have attained a number of sports certifications such as the Level1Certificate Club Coach and Football Club Administration from FA Learning. Question 2: Categorization The first activity, planning and preparing coaching sessions is a sporting activity. This is because it requires sports skills to accomplish. These include knowledge of sports fitness, sports management activities and professional skills relating to sporting in general. Planning coaching sessions requires practical skills. There is also need for knowledge relating to issues such as the intensity of training, the right diet, the time that training will take, breaks in between training and the need to achieve the overall training objectives. Essentially, the planner has to take into consideration knowledge and understanding of the sport, have cognitive skills and generally approach coach ing sessions from a professional perspective (Garland, Malcolm, & Rowe 2000). The second activity, actual coaching of children, is a physical activity. This is because coaching in today’s society demands the physical input and practical participation of the coach. Giving a player the instructions to conduct an activity for instance is not as effective as actually showing them what requires to be done. As such, the coach participates as much as the players in the activities scheduled for a coaching session. This fact can be explained through the transformation of the sports arena from the early 1900 when a swimming instructor, for instance, would guide a swimming session from the sidelines of a pool and would assist a troubled swimmer, without necessary getting into the water, with a long pole. In contrast, today’s swimming instructor is always in a swim suit ready to dive into the water should the need arise. In addition to this, swimming instructors get into the water themselves during training sessions, practically illustrating the body movements necessary (Study Guide 2008). People hold different views towards such activities however. One may view the planning and preparing of coaching sessions as a recreational activity for instance. Coaching of children may be viewed as a sporting or recreational activity. The difference in perception and variance in views relating to these activities can only be explained by the fact that people go through different experiences and posses different interests in life. As such, it is unlikely to achieve a convergence of opinion on sporting issues. Some people for instance believe that the use of technology in refereeing football matches will increase accuracy, reduce disputes and generally enhance the football game. On the other hand, others think that it will deny the game the rawness that makes it so exiting (BBC News 2005). Question 3: Perpectives Scientific perspective Scientific developments have indeed improved planning and preparations of coaching sessions. Technology is significantly employed in football coaching in today’s environment. As such, a coaching planer has to take into consideration the impact that technology will have on coaching sessions and its use in delivering the actual coaching. In football coaching sessions, technology is used in producing simulations of player positions and play strategies and producing statistics on a given play (BBC News 2005).

Political Parties and the Electoral Process Essay - 2

Political Parties and the Electoral Process - Essay Example It is, therefore, important to examine the differences between the Democratic and Republican parties, the role that campaigns have played in maintaining this two party system, and the reasons why third party candidates have never been successful at the national level in a Presidential election. Ideological Differences There are many differences between the Republicans and Democrats, but let us on three fundamental areas that are often raised in political discussions. Abortion, for example, is one issue that has divided the political spectrum fro decades. Generally speaking, Democrats support the right of a woman to have an abortion, commonly referred to as being pro-choice (Bolce & Maio, 2002). Republicans, on the other hand, are generally considered to be pro-life and believe that abortion should be illegal. Consider the military. While both parties obviously are proud of the military and believe whole heartedly in America’s right to defend itself, Democrats are in favor of a smaller military and less spending on this area. Republicans, however, typically argue for increased spending on the military and its various services (Pletka, 2013). Finally, we can point out differences on the environmental front. Democrats are generally supportive of policies aimed at protecting the environment, while Republicans are considered to be much more cautious in this area and look to the private sector to take the lead (Newport, 2009). The Campaign Process and Third-Party Candidates Lack of Success It has been said that money dominates America’s political system, and perhaps nowhere can this be demonstrated more than the campaign process. With the largest businesses and private individuals giving substantial sums of money to one of the two major parties, it becomes readily apparent why third party candidates have struggle to even get on stage with one of the other Presidential contenders, much less make an impact. Candidates from the Republican and Democratic pa rties dominate the airwaves during a Presidential campaign, while third-party candidates struggle to have enough money to put up campaign posters. In addition, since candidates must separately register in each of the 50 states in America, the grassroots effort must be tremendous (Colquitt, 2008). As each of the two major parties have hundreds of thousands of supporters in any given location, this is relatively easy for them to accomplish. Third-party candidates, however, generally have extremely localized support, making it nearly impossible for them to get on the ballot in all 50 states. Since America’s electoral system takes into account state votes separately from one another, third-party candidates find themselves at a comparative disadvantage right out of the gate. For these reasons, and other, the political system in America continues do dominate the office of President, and that will likely continue for the foreseeable future. Conclusion While certain third-parties hav e certainly made inroads into the political system at the local level, there role in the national system certainly remains negligible at best. There are ideological differences, to be sure, between the two major political parties. Political fighting has grown at a feverish pace
