Child Watch TV is good or not Essay Example | Topics and Well Written Essays - 500 words

Child Watch TV is good or not - Essay Example Several researches around the world has shown that on an average children who consistently spend more than 4 hours per day watching TV are more likely to be overweight. In earlier days before the television, children played outdoors more and used their minds to be more creative. Today, obesity is a major problem among children and health experts point out that television plays a major role in this. Excessive television viewing promotes inactivity and when it is combined with frequent snaking it leads to obesity. In addition, children are more and more influenced by advertisement and through television they're also bombarded with messages that encourage them to eat unhealthy foods such as potato chips and empty-calorie soft drinks that often become preferred snack foods. There is no doubt that television has its good side. It can be both entertaining as well as educational. It gives good opportunity for children to learn more about different cultures, and gain exposure to ideas they may never encounter in their own community.Besides, it also gives them a chance to see different places and learn about various aspects on culture in different parts of the world. However, if we think of a situation where there was no television, children who have an interest to learn about these aspects could use books and other sources to know about these things.

What is the Investment case for floating of offshore wind turbines Essay

What is the Investment case for floating of offshore wind turbines - Essay Example Future climate alteration and connected effects will change from place to place all over the world, according to the IPCC report. The impacts of a growth in worldwide temperature comprise of an increase in the levels of sea and a variation in the quantity and pattern of precipitation, as well as a possible growth of subtropical deserts..One among the many proposed policy responses to global warming is the investment of offshore wind power, according to the 2013 Report of the European Wind Energy Association. Compared to the environmental effects of conventional energy sources, the environmental wind power effect is minor, a bit high than the environmental effect of hydro-water on a life-cycle basis. Different from electricity resulting from fossil fuels and nuclear power firms, wind power consumes no fuel and, emits no air pollution in operation. What is the Role of Fukushima Floating Offshore Wind Turbine Generating power? The Fukushima event played a significant role in this techno logy of floating offshore by setting up a sub-station, which was the only one of that type in operation. A development to tap the wind power about 20 kilometer off the coast of Fukushima, the region where the March 2011 nuclear disaster took place, started producing power based on operation, according to the report published on Bloomberg.com(http://www.bloomberg.com/news/print/2013-11-11/fukushima-floating-offshore-wind-turbine-starts-generating-power.html) The project that was funded by the government is a sign of Japans interest to develop the technology which has not yet been proved for floating the wind powers off the coast and its aim to change quake-ravaged Fukushima into an outstanding centre for energy production.†Fukushima is gaining ground in...Offshore wind ability is growing fast, from 4 GW (gigawatts) in 2011 to 175 GW by 2035, its development being underpinned by administration support," according to the International Energy Agency's 2012 World Energy Outlook rep ort (pages 226-227). This leads us to the question; what is the Investment case for floating of offshore wind turbines and for onshore wind turbines? Introduction This paper is meant to investigate the investment case for floating offshore wind turbines and for onshore wind turbines. Throughout the paper I will discuss various modes of offshore and onshore wind technology and how various nations across the globe have adapted that source of energy .Also throughout the paper I will discuss the various companies in the business of production of wind turbines and their rate of investment in the technology. What is driving the development and deployment of the technology? Global warming is the increase rise in the regular temperature of Earth's ambiance and oceans ever since the late 19th century and its predictable continuance. The Bloomberg report helps explain that a traditional floating offshore wind turbine tower that is constructed upward from the seafloor results to be too expensive to install in waters deeper than 50 meters, and this is a big issue for Japan since a continental shelf varying from 50 to 200 meters deep surrounds its coast.

View Of Men And Women Media Media Essay

View Of Men And Women Media Media Essay Of the many influences on how we view men and women, media are the most pervasive and one of the most powerful. All forms of media communicate images of the sexes. Many of these media perpetuate unrealistic, stereotypical, and limiting perceptions. From a very young age, people are subjected to norms or standards for how each gender should act. Advertising is necessary today. Whether you have a small business or a large one, you must tell groups of people who you are, what you sell, and where you are located. You must tell them when they wish to hear or read about such things.TV advertising affects gender identity by reinforcing stereotypes. Advertisers carefully create their TV advertisements to send a particular message about gender. Television advertising plays an important role on changing consumer behavior and attitudes and gave consumers new patterns about identity. In my research I would like to focus on the fact that  the formation of gender identity and the inequality of g ender are due to many internal and external factors. I will also try to show that TV is the most common media that represent the difference of gender and influence our view to the state and position of men and women and  I will also attempt to specify gender stereotypes, which are used in advertising as a persuasion technique.

Figure 2: Chart 2: Making the appearances to the model presented in TV advertisement LIST OF SYMBOLES TV: Television Ads: Advertisements INTRODUCTIOIN   The world is moving towards progress in every walk of life. But when we look towards societies, it feels as if something is still missing. Social issues are matters which directly or indirectly affect many or all members of a society and are considered to be problems related to moral values. Social issues include poverty, violence, corruption, bribery, suppression of human rights, discrimination, crime, killing in the name of honor, gender identity and inequality in rights etc. Mass media play a significant role in a modern world, by broadcasting information  in fast pace and giving entertainment to vast audiences. Media is a pervasive and profoundly influential socializing force.   It is the most powerful tool of communication. It helps promoting the right things on the right time. It gives a real exposure to the audience about what is right or wrong. Even though, media is linked with spreading news, it helps a lot to inform us about the realities and it has a constructive r ole to play for the society. Media consist of press, television, radio, books and the Internet. The latter is now the most developing medium; however, TV also has a wide field of influence.  TV is the most powerful common type of media due to its extensive worldwide spread. It plays a significant role in the development of many social issues. It plays an important role in order to focus on the social issues in almost every era. It is the most commonly media used by people in our daily lives, it insinuates messages into our consciousness at every turn. Today News Channels are spokesperson of some social issues, which helps us to estimate the realities of lives. By creating a certain type of message, TV can manipulate peoples attitude and opinions.  Ã‚  All forms of advertisement in TV communicate images of the sexes, many of which perpetuate unrealistic, stereotypical, and limiting perceptions.  Advertising has the power to persuade, the power to influence the mind and shape destiny. It has the power to cha nge markets and improve profit margins. Advertising has short-term power conveying new information, building awareness, enhancing credibility, and long-term power conveying brand image, attaching emotional values to the brand, building positive reputation, etc. The prevalence or predominance of power of gender and formation of identity, in the media and especially TV, is one of the most important issues now a day.  Gender identity develops through a process of differentiation: interactions of biological, social, and cognitive-learning factors that occur over time. Differentiation means that a basically similar structure develops differently depending upon the influence of other factors such as media. In other word various influences increase the difference between the sexes.  Ã‚  At birth, almost all children are socially labeled as either a girl or a boy, based on the appearance of the external genitals. The child begins to develop a body image of the self as a girl or a boy. After the child acquires language, by eighteen months to two years, the child can label the self as  girl  or  boy.  This is the early expression of gender identity. Learning of some aspects of gender identity occurs at biologically sensitive periods of ti me and once it is learned it is difficult to alter. All societies partition some aspects of human existence into two distinct roles of male and female. The specific content of female and male gender roles varies among different societies. These characteristics may or may not be closely related to the biological functional differences between females and males. The difficulty that children face in the learning process is determining which characteristics are gender-linked and which are not. Children develop gender-identity constancy by five to six years of age. Gender is the idea that if a child is a girl, she will always be female and will grow up to be a woman; if a child is a boy, he will always be male and will grow up to be a man. These continuities are not obvious but must be learned. Gender identity is consolidated through social experiences and gender characteristics, which may include games, changes in the sexual characteristics of the body and media. Usually these changes are consistent with the gender identity and gender rol e. These physical changes must be incorporated into the gender identity. Standards of feminine or masculine physical attractiveness change from childhood to adulthood, as do other aspects of gender roles. Social pressures intensify for conformity to female or male gender roles. In addition, the sex hormones fuel romantic and sexual interests. Sexual orientation, as heterosexual, bisexual, or homosexual, also becomes part of an adult gender identity and role, although it originates much earlier in development. Although gender identity as man or woman is stable, some of the content of an individuals gender role may change over a lifetime because of changing social norms, a move to another society or over the impact of media. The conceptualization of the self as male or female is a basic part of human identity in all societies. A distinctive gender identity may be linked to sexual behavior and cross-gender social presentation in different parts of the world. This gender identity includes individuals who do not fit into the societys traditional masculine or feminine sex roles. With great satisfaction we were then able to assert that sex is a biological designation, and gender is a set of socially constructed expectations for women and men. That distinction permitted us to make claims about material conditions, historical moments, and cultural pressures. In short, the separation of sex and gender allowed us to point to social constructions, not biological. Also  gender is called a gender  because it was originally called a sex but sex was too inappropriate for kids so they came up with a new word for the same meaning. To sum up things,  Gender Identity  refers to a persons private sense of, and subjective experience of, their own  gender. This is generally described as ones private sense of being a  man  or a  woman, consisting primarily of the acceptance of membership into a category of people:  male  or  female.  All societies have a set of gender categories that can serve as the basis of the formation of a  social identity  in relation to other members of society. Basic gender identity is usually formed by age three and is extremely difficult to change after that.  Although the formation of gender identity is not completely understood, many factors have been suggested as influencing its development. Biological factors that may influence gender identity include pre- and post-natal hormone levels and genetic makeup.  Ã‚  Social factors which may influence gender identity include ideas regarding gender roles conveyed by family, authority figures, mass media, and other i nfluential people in a childs life.  Child are often shaped and molded by the people surrounding them by trying to imitate and follow. Ones gender identity is also influenced by the  social learning theory, which assumes that children develop their gender identity through observing and imitating gender-linked behaviors, and then being rewarded or punished for behaving that way.  In some cases, a persons gender identity may be inconsistent with their biological sex characteristics, resulting in individuals dressing and behaving in a way which is perceived by others as being outside cultural gender norms.   In short  Gender is one of the most studied social paradigms as it is the main paradigm that people use in determining how to act and interact with others. For this reason, it is important to look at the ways in which individuals receive messages about gender norms from media and especially TV because television advertisements is the most common and used medium that transmit cultural ideas about gender, help to socially construct gender and affect the way that people think about their own gender, and contribute to the ongoing social stratification of genders in society. Literature Review Televisions effect on viewers is a subject that has been extensively studied in the last twenty years and whose impact extends farther than most people realize. Many studies have focused on how television advertisement affects the formation of gender identity. Gender Identity Formation and Gender Role Sociologists are particularly interested in gender identity and how it determines gender roles. Genetics, hormones, differences in the brain, and socialization all interact to mold a persons gender identity. In order to understand gender identity development and related issues, definitions must be emphasized for clarity. Gender identity refers to the feeling that you are male, female or transgender. In other word, according to WIKIPIDIA Gender identity  refers to a persons private sense of, and subjective experience of their own  gender. This is generally described as ones private sense of being a  man  or a  woman, consisting primarily of the acceptance of membership into a category of people:  male  or  female.  All societies have a set of gender categories that can serve as the basis of the formation of a  social identity  in relation to other members of society. Many things contribute to the formation of gender identity, including cultural differences societ y, family and factors that are in place before birth. In one hand, Cross cultural findings show that variations in gender role between different cultures are consistent with the idea that gender role behavior is learned. The study of Hofstede identified five distinct cultural dimensions that served to distinguish one culture from another. Masculinity (MAS)  is one of these five dimensions it refers to how much a society sticks with, and values, traditional male and female roles. High MAS scores are found in countries where men are expected to be tough, to be the provider, to be assertive and to be strong. If women work outside the home, they have separate professions from men. Low MAS scores do not reverse the gender roles. In a low MAS society, the roles are simply blurred. You see women and men working together equally across many professions. Men are allowed to be sensitive and women can work hard for professional success. For example, and of course according to the study of Hofstede, Japan is highly masculine with a score of 95 whereas Sweden has the lowest measured value. In addition (according to Hofstadters analysis), if you were to open an office in Japan, you might have greater success if you appointed a male employee to lead the team and had a strong male contingent on the team. In Sweden, on the other hand, you would aim for a team that was balanced in terms of skill rather than gender. On the other hand, Socialization, or the process by which a child learns the norms and roles that society has created for his or her gender, plays a significant role in the establishment of her or his sense of femaleness or maleness. If a child learns she is a female and is raised as a female, the child believes she is female; if told he is a male and raised as a male, the child believes he is male. From the birth, most parents treat their children according to the childs gender as determined by the appearance of their genitals. Parents even handle their baby girls less aggressively than their baby boys. Children quickly develop a clear understanding that they are either female or male, as well as a strong desire to adopt gender-appropriate mannerisms and behaviors. This normally occurs within two years, according to many authorities. In short, biology sets the stage, but childrens interactions with the social environment actually determine the nature of gender identity. However, parents do not directly teach gender role behaviors to their children through selective reinforcement and punishment but that children acquire gender appropriate behaviors nonetheless. It may therefore be that the learning of gender role occurs through processes other than those specified by social learning theory. Social learning theory has difficulty explaining how childrens understanding of gender ch anges over time. It also cannot easily account for how childrens preparedness to imitate a gender role behavior depends more on whether the behavior is seen as gender appropriate than the sex of the model demonstrating it. The main way that gender behaviors are learned is through the process of observational learning. Children observe the people around them behaving in various ways, some of which relate to gender. They pay attention to some of these people and encode their behavior. At a later time they may imitate the behavior they have observed. They may do this regardless of whether the behavior is appropriate or not. The child is more likely to attend to and imitate those people it perceives as similar to itself. Also, the child will also have observed the consequences of her parents behavior and will be motivated to imitate the behavior it has seen reinforced and avoid imitating the behavior it has seen punishedà ¢Ã¢â€š ¬Ã‚ ¦ For example, imagine three siblings, Raed (4 years), Aziz (5 years) and Ranim (6 years). Ranim and Aziz plays dressing up and both put on dresses. Their dad reinforces Ranim for this, by saying she looks pretty but punishes Aziz by saying he looks silly and boys should not dress that way. In future, Ranim is more likely to wear dresses and Aziz is less likely. Raed, who has been watching all this, is unlikely to imitate the behavior of wearing a dress because he has seen his brother (who he perceives as similar to himself) getting punished for doing it. Children around the age of two years playing at home with their parents, recording the reinforcements and punishments the parents provided. Boys and girls were reinforced and punished for different behaviors. Boys were reinforced for playing with gender appropriate toys (e.g. bricks) and punished for playing with dolls. Girls were reinforced for staying close to the parent and punished for rough and tumble play. This confirm that boys and girls are reinforced for gender appropriate and punished for gender inappropriate behavior, lending support to the idea that gender role behavior is learned from the childs environment. How TV affect the Development of Gender Identity As well as, just as a mirror reflects the visual image of ourselves, we also rely on an even bigger mirror to reflect back a reality of ourselves in a collective environment: mass media. It is through this mirror that we are able to understand our identity through a social reflection of reality. Mass media, and specifically television, have impacted the amount and context in which images and cultural symbols are exchanged across physical and cultural borders. According to Clive Barnes (b. 1927) British drama critic, Television is the first truly democratic culture-the first culture available to everybody and entirely governed by what the people wants. The most terrifying thing is what the people do want. In addition Anthropological accounts suggest that the growth of TV has had large effects on a wide range of day-to-day lifestyle behaviors, including latrine building and fan usage. Television today is the first and foremost storyteller, unlike olden days when parents, schools and books told most of the stories. TV presents to us stories about what is good and bad, the happy and sad, the success and the failures and it tell us who is on the top and who is at the bottom.   Furthermore, the influence of TV advertising on gender identity clearly seems to be a daily situation. Actually, TV publicity objective is to directly attack the human personality to develop certain attitudes and postures in relation to certain products, TV programs, goods and services, politic movements and other related organizations and social economics movements this create serious problems and consequences on personal identity and free personality evolution. When we see the front of an advertisement in TV we tend not to see the headlights and the grill as a symbolic representation of the human face, because instead, we see the TV as an image in and of itself. Yet the image of the TV itself represents a broader connection to our identity for it contains a takenà ¢Ã¢â€š ¬Ã‚ for granted symbolic reflection of our own nature. In short throughout human collective consciousness, the impact of images and symbols on the construction of identity is integral in our definitions of self. Whether we like it or not, our world is no longer contained by the constructs of geographic boundaries. No longer are we limited to our natural born surroundings; due to TV we now have access to information, ideas and culture from any place on the globe. Our generation is now confronted with the complexity of choice to be whoever you want to be. Identity is up for mass media and TV in special which brings exposure of ideas of choice and freedom to all who have access to its message, regardless of their former national or cultural identification. This Information Revolution carries its own implicit and explicit agendas across borders and cultures, whether welcomed or not. It has provided modern human beings with new abilities and skills, allowing them to acquire an incredible capacity in the manipulations of culturoà ¢Ã¢â€š ¬Ã‚ symbolic elements. This everà ¢Ã¢â€š ¬Ã‚ growing electronic media technique for rapid global and instant transmission around the world of the oral and written words, ideas, beliefs cultural values, voices, images and so on, has already reached a sophisticated and impressive level. These mediaized cultural symbols heavily influence the interaction, analysis and constructions of collective identity, manipulating our perception of who we are both as an individual and as part of a specific cultural group. Television rely on cultural symbols, which are instrumental to our basis of cultural identity and knowledge, thus it can be inferred that television as a visual medium is the most influential mouthpiece of group identity. With satellite television, more accessible and affordable than change our perspectives of ever before, it is not hard to imagine that television is the most direct and influential way to spread information, ideas or symbols. According to Marie Winn and her  essay  Ã‚ «The Plug-In Drug,  » television has various negative effects on our society today. In her essay Winn explores the ways in which television has harmfully caused disruptions with the quality of family life, rituals, and values. She recognizes there is a problem with society and the way in which it is consistently influenced by television. I am able to agree with Winn on this point, but I do not feel that the totality of the influence is negative. Television today has a lot of positive effects and influences on our society and our Tunisian culture; it gives us helpful information, various forms of  education, and entertainment Throughout the years, the Tunisian people have come to rely on the television and all it has to offer. The television with its multi-purposes has positively affected our society through its means of information, education, and entertainment. We as Tunisian people have become a part of a society which is greatly influenced by the television. Furthermore, this influence has been proven to affect the quality of family life, as Winn mentions in her article  «The Plug-In Drug.  » The positive effect of television on our society as a whole, and the knowledge it provides is far greater than this quality of life that she mentions. I must admit that there are both positive and negative aspects that come out of our televisions today, but I feel that the positive effects definitely outweigh the negatives when it comes to the importance of information, education, and entertainment for our society. The Impact Of TV Advertisement On Gender Identity Gender representation, on the smallest scale, has, always, been important for one to understand what it means to be male or female. So to look at it in terms of advertising and specially advertisement presented in TV, which is considered the most powerful and influential medium in the society, is to look at it with a more serious eye. From the images inflicted upon us in TV we see man and woman different. For a man that means being tough, intelligent, serious, competitive and business minded while for a woman, that means having beauty, elegance, passivity and good domestic ability. According to the article of Jessica Furgerson, The Influence of TV Advertising on Gender Identity, a Research conducted in 1998 notes that TV commercials show boys as active and dominate, yet shows girls as giggly and shy. TV commercials also demonstrate what type of behavior is appropriate for boys and girls by dictating which toys are for girls and which toys are for boys. The representation of how boys and girls should act and what they should play with sends a message to the viewer of what is appropriate, thus shaping the gender identity of the viewer. The impact of TV advertisement on males identity Positive impacts TV advertisement presented men as rational, ambitious, smart, stable, competitive,  powerful, independent, and tolerant. He is also Strength, performance, and skillful. In addition he is the Cultural standard may be because in society and especially our Arab societies Men have considerably more economic and political power than women, According to the article of Jessica Furgerson The Influence of TV Advertising on Gender Identity Television advertisers place men in two distinct roles: the bread winner and the heterosexual male. Initially, TV advertisements commonly depict men as knowledgeable, hard working, powerful and successful; this depiction tells men that to be a man you must take care of your wife and kids and possess these qualities. Negative impacts According to the document Gender issues in the Media  , masculinity is often associated with machismo, independence, competition, emotional detachment, aggression and violence. Despite the fact that men have considerably more economic and political power in society than women, these trends although different from those which affect women and girls are very damaging to boys. This means that Men are associated with emotional detachment, aggression and violence. For example most of the toys presented in TV for young boys are all toys of war like pistol, tank and sword. This teach young boys how to be violent and make him aggressive, hard and sometimes without feelings. Children learn from these advertisements that the suitable character for him is to be violent and aggressive. That is TV advertisement affect negatively the gender identity of men. The impact of TV advertisement on females identity Positive impacts In TV women are attractive, sensitive,  romantic, warm, peaceful, fair, submissive, timid and desirable. In addition, Women are patient, happy and sociable as it is said in the Essay (the influence of TV on gender identity) which was wrote by  anaconda,  University, Bachelors,  A+,  May 2005 Housewives are seen as happy to serve others and to relinquish their spare time and personal needs; all in an effort to insure that their families fell loved and cared for. She is presented in advertisements as the good wife and the strong and patient women who spend the spare time in looking after children and doing the best to make all members of society happy. b. Negative impacts According to the article of Jessica Furgerson The Influence of TV Advertising on Gender Identity TV advertisements cast the female character in one of two ways: the home maker or the sex object. Initially, women are consistently shown in the home, supermarket or shopping in order to reinforce the role of the woman in the domestic sphere. On the other hand, women are also portrayed as sex objects, almost always shown in provocative clothing delivering a clearly sexual message. By continually telling women that they should be doing these things, viewers see such behavior as the norm and frame their gender identity around it. In addition TV emphasizes traditional roles and normalizes violence against women. Women are usually in the home, performing domestic chores such as laundry or cooking; as sex objects that exist primarily to service men; as victims who cant protect themselves and are the natural recipients of beatings, harassment, sexual assault and murder. Furthermore and according to an Essay (the influence of TV on gender identity) which was wrote by  anaconda,  University, Bachelors,  A+,  May 2005 Day time advertisement on television tend to portray men in stereotypical roles of authority and dominance, while women are associated with traditional roles of housewife. She also said that Females are shown maintaining the perfect household, with their primary goal being to take care of the house their husband and or family. The reason for this could be the fact that men dominate the workplace. According to an article of Dow (1995:200, cited in Holtzman 2000:80) 3% of directors in general ar e women. The advertising industry itself has a particularly high man to female ratio and based on statistics produced, it was revealed that only 17 out of 244 advertising directors were women and in an industry so greatly dominated by men is it not likely that consciously or subconsciously the adverts produced will be biased. This means that Women are unimportant or invisible and play a second role in society and less likely to be shown in TV. Even with the bigger freedom of choice given to women nowadays we are still to a certain extent living in a society which looks through the males gaze where women are still being portrayed as being dependent on men. Evaluating TV Advertisements As we have mentioned above TV advertisement impact negatively the consumer and especially their gender identity. Evaluating TV advertisement is better both for the advertisers and for the consumers. On the one hand the type advertisers use to keep stores name and merchandise before the public. With advertisements you remind people week after week about your regular merchandise or services or tell them about new or special services or policies. In addition advertising should create in the minds of customers the attitude you want them to have about your store, its merchandise, its services, and its policies. To some degree, all advertising should be evaluated because it is your reputation builder. Evaluating advertising requires tracking and analyzing message. Therefore, both marketing professionals and advertisers employ a variety of techniques to evaluate the success of TV advertisements. In addition to that and essentially, measuring results means comparing sales with advertising. I n order to do it you have to start early in the process before you even make the advertisement. Also you must listen to what people say about your advertisements and of course take it into consideration. In doing so, advertisers must discover their mental framework within which any comment about their advertisement was made and find points which reinforce believability and a feeling that your product fulfills some wish or need. However, you should not be misled by what people say and you must see that their advertising does the job they want it to. On the other hand TV advertisement must be evaluated for the benefit of consumer and to protect him from any types of delude. Furthermore, it is important to assess the impact of TV on consumer and especially its impact on the creation of gender identity and gender role representation. The consumer protection organization should be present in doing this and I think that the creation of a new brand under this organization which main role is an protecting gender identity from stereotypes in media in general and in TV advertisement in specific in now a day a need. In addition Parents and teachers can have a much greater impact on a childs development than the media to which the child is exposed. They must teach and explain to children to understand that media do not reflect reality; that they communicate implicit and explicit values; and that they can influence the way we feel and think about ourselves and the world, are vitally important lessons towards achieving a society in which wom en and girls are seen and treated as equal to men and boys. METHODOLOGY The main aim of this chapter is to present the survey methods used to conduct this research. Therefore interview and questionnaire were included in this research process as method or instrument of data collection. Primary source: interview and Questionnaire Interviews Interviews: are questionnaires administered in person. I rely on the use of it because it is most personal and produce better rates. In fact, direct contacts were made with a group of students of the UNIVERSITY OF JENDOUBA Higher Institute Of Human Sciences (Each student was asked alone). The interview will deal with how people identify themselves and what their lifestyles are. Questionnaire The questionnaire will give us information about how TV affects the development of gender. It is designed the same students who respond to the interview. First I use the questionnaire because it is Practical and it can bring a Large amounts of information can be collected from a large number of people in a short period of time and in a relatively cost effective way. It can be carried out by the researcher or by any number of people with limited affect to its validity and reliability. The results of the questionnaires can usually be quickly and easily quantified by either a researcher or through the use of a software package. It can be analyzed more scientifically and objectively than other forms of research. When data has been quantified, it can be used to compare and contrast other research and may be used to measure change. Secondary source: advertisement presented in TV In my research I relay on the advertisements presented on vario

Avian Song Control :: Birds Bird Neorology Essays

Avian Song Control Bird songs continue to fascinate neurobiologists and neuroethologists because the development of song has been a popular model used to examine the role of environment on behavior. In most species, only male birds sing complex songs. Their vocalizations are the result of sexual dimorphism in the brain regions responsible for the production of song. However, this behavior is not genetically hardwired into the avian brain. Certain conditions must exist in order for male birds to successfully produce their species-specific song. Additionally, the neuronal circuitry and structure of the avian song system shows high levels of plasticity. If the brain and behavior are indistinguishable, then the structural differences in the avian brain are responsible for behavioral differences across the sexes. Nottebohm and colleagues identified six anatomically distinct regions of the forebrain involved in the production of song, which are arranged into two independent pathways, the posterior pathway, which controls song production, and the anterior pathway, which controls song learning. The collective unit is typically referred to as the vocal control region (VCR) (1) (2). Female birds sing rarely and this behavioral difference is reflective of the anatomy of the female avian brain. There are significant differences in the size of three neural areas involved in the production of song across the sexes, and a specific area, Area X, is present in the male and absent in the female. Additionally, the incorporation of radiolabeled testosterone in certain locations is different in males and females (3) (4). Scientists have been particularly interested in the origin of the structural differences in male and female songbirds. Research has suggested the importance of gonadal hormones, specifically testosterone in the production of song. It was observed that castration eliminated all song production (5). Additionally, when testosterone levels are low, there is not only a decrease in the production of song, but also a decrease in the size of some nuclei involved in song production (6). Further support for the necessity of testosterone for song production was demonstrated by Nottebohm (1980) when he injected female birds with testosterone, which lead to the production of song (7). This research has interesting implications regarding anatomical changes that may occur when an organism is chemically imbalanced. Disruptions in chemical equilibrium may alter brain structure and subsequently influence behavior. Nevertheless, not all research has supported the claim that testosterone is responsible for anatomical and behavioral differences between male and female songbirds.

Additionally, the incorporation of radiolabeled testosterone in certain locations is different in males and females (3) (4). Scientists have been particularly interested in the origin of the structural differences in male and female songbirds. Research has suggested the importance of gonadal hormones, specifically testosterone in the production of song. It was observed that castration eliminated all song production (5). Additionally, when testosterone levels are low, there is not only a decrease in the production of song, but also a decrease in the size of some nuclei involved in song production (6). Further support for the necessity of testosterone for song production was demonstrated by Nottebohm (1980) when he injected female birds with testosterone, which lead to the production of song (7). This research has interesting implications regarding anatomical changes that may occur when an organism is chemically imbalanced. Disruptions in chemical equilibrium may alter brain structure and subsequently influence behavior. Nevertheless, not all research has supported the claim that testosterone is responsible for anatomical and behavioral differences between male and female songbirds.

Air Industry Analysis Essay

Executive Summary Airlines companies are undergoing major changes to cope with the new challenges of the modern economy. Geopolitical factors, such as war and terrorism, the financial crisis of 2009, high entry barriers, as well as extreme weather events, are some of the factors that are driving these changes. Costs in fuel prices, wages and ticket prices are some of the demand drivers of this multi-billionaire industry. Also, there has been an industry-wide shakedown, which will have far-reaching effects on the industry’s trend towards expanding domestic and international services. The perception that air travel is an ordeal continues to grow, making it very difficult for airlines to charge the higher prices that are necessary to return to profitability. Today Airlines provide a vital service, but factors including like the continuing existence of loss-making carriers, bloated cost structure, vulnerability to exogenous events and a reputation for poor service combine to present a huge impedime nt to profitability. While a handful of low-cost airlines have successfully managed to post consistent profits, by and large, profitable airlines are few and far between. Introduction The global airline industry provides transportation to virtually every corner of the world. The airline companies employ many people, hold multi-billion dollar equipment inventory, and generate billions of dollars in yearly gross revenue. It facilitates economic growth, world trade, international investment and tourism. However, the industry can be very vulnerable to government regulations, economic influences, extreme weather events and geopolitical factors such as war and terrorism. The SIC/NAICS code for the industry is 4512 /4811. The NAICS term for the industry is â€Å"Scheduled air transportation† . The industry is further classified into 2 NAICS codes – 481111 for Scheduled passenger transportation and 48112 for Scheduled Freight Transportation. Per NCAIS, â€Å"This U.S. industry comprises establishments primarily engaged in providing air transportation of passengers or passengers and freight over regular routes and on regular schedules. Establishments in this industry operate flights even if partially loaded. Scheduled air passenger carriers including commuter and helicopter carriers (except scenic and sightseeing) are included in this industry.† History The commercial airline industry in the US grew at a fast rate after the World War III. The commercial aviation industry in the United States has grown dramatically since the end of World War II. In 1945 the major airlines flew 3.3 billion revenue passenger miles (RPMs). By the mid 1970s, when deregulation was beginning to develop, the major carriers flew 130 billion RPMs. By 1988, after a decade of deregulation, the number of domestic RPMs had reached 330 billion (Source: Winds of Change). Up to the 1970s the industry was heavily regulated around the world. However, in 1976 under the recommendation of the Civil Aeronautics Board (CAB), the regulatory system was dismantled by the US Congress. Most of the industrialized world soon followed suite. The Airline Deregulation Act passed in the US in 1978 eased the entry of new companies into the business and gave them freedom to set their own fares and fly whatever domestic routes they chose. This lead to a swarm of new entrants, lower fare s and the opening of new routes and services to all over the country. Organization The major Capital expenditure for the airline industry is the cost of the airplanes. Boeing and Airbus are the two major providers of aircrafts to the industry. Other than that the Airports Authorities are the other major service providers to the airline industry. Airline fuel is another major product the the industry buys from external suppliers. The industry itself provides the rest major services- Flight operations, aircraft maintenance, passenger service ( (in-flight food, flight attendants) and Aircraft traffic services (baggage and passenger handling). Governmental Factors As mentioned earlier government factors play a big role in the industry. The growth of the industry post the 1976 deregulation illustrates this point. Government policies that impact the economy also have a big impact on the industry profits as was seen during the 1990 global recession and the 2001 US economic downturn. Wars and Geopolitical tensions that impact the airline fuel supplies also pose threat to the industry. Environmental Factors Environmental factors such as bad weather conditions can force planes to be delayed, canceled or even to divert to another airport. In such cases the airlines are forced to pay for lodging and meals of the affected passengers and in some cases refund tickets. An extreme sample of this is the airline disruption caused by the ash from the volcanic eruption in Iceland in 2010. It could have cost the industry more than $1.7 bln according an estimate by the International Air Transport Association (IATA). Market Structure The airlines industry has undergone major changes since 1978 due to the deregulation and the economic liberalization, where restrictions on the routes and fares charged were removed. Thus in order to obtain the cost efficient and to concentrate traffic to one airport the Hub-and-spokes was created to move passengers from smaller cities and gathered a group of passengers in a major city airport to be transported from a major hub of one city to another major hub. This new system allows the airline industry to retain the oligopolistic market due to the huge barriers that obstruct competition. From one hand the government regulations established barriers for airports such us a slot management system that demonstrate there is a failure in the investment of governments in adequate infrastructure, gate constraints due to exclusive leasing arrangements and gates usage in congested cities is limiting the entry despite the share usage between airlines. â€Å"Airlines need certainty because they have invested billions of dollars in aircraft. They must be certain they will have access to the infrastructure for the next 25-30 years and this is why historic (grandfather) rights are appropriate.† (Airlines International, 2010). On the other hand the hub and spoke system allows major airline firms to restrict the entrance of new competitor, because they have captured the market of small and big cities with a large economy of scale and a big profit margin, price flexibility, and other rights like reserved slots that was very difficult to be matched by new airlines, protecting them from new competitors developing a mature oligopoly where the prices are set by the leaders and the others airlines followed, practicing parallel pricing. All the studies reviewed suggested that despite the benefits of airline deregulation, there are many factors that continued preventing airlines to get advantage of this economic deregulation due not only to the airport restrictions but also due to computer-reservation systems, benefits of frequent-flyer programs, economies of scale of operation. This fact can be evidence after the deregulation when many new airlines attempted to get into the market but the majority failed due to the high cost associated with gates, slots and other airports facilities did not let them to compete with prices as a result this new competitors were acquired by the already established ones. (Seng, 2007) According to RITA, the U.S., Research and Innovative Technology bureau Transportation’s statistics the largest carrier for domestic market from May 2011 through April 2012 was Delta followed by Southwest and American (see table No.1.) It is important to mention that with the merger of United and Continental, they could become the largest carrier if the tendency remains. (Jenkins, 2011) As we can observe, the 55.9% of the market is hold by Delta, Southwest, American, and United,. In order to open the market for new carriers and generate airfare competition the government has to work on expanding the access to new gates, baggage claim areas and slots, otherwise the existent oligopolistic market will continue prevailing. Industry Demand The US airline industry demand is affected by the current market that has generated unstable conditions due to the high dependency and reaction to many factors like regulation, fuel price, inflation, security and competition. In addition this industry was also affected by the financial crisis during 2009 that had a great impact in market demand, thought due to the revival of the economy the travel demand has started improving since 2010. According to RITA â€Å"There were 2.1 percent fewer passengers in the April 2009 to April 2010 period compared to April 2008 to April 2009. From the year ending April 2010 to the year ending in April 2011, system wide passenger numbers on US airlines increased 2.9 percent† (Smallen,2011) As a result of the deregulation of the airline industry in 1979 the traffic of passengers increased and the ticket prices decreased. In this environment there was more competition and less demand, the operating cost and margin profit were affected and the maj or firms filed for bankruptcy falling from six major airlines (united, America, Delta, Eastern, TWA, and Pan Am) to three by 1991 (United, American and Delta). The new challenge for airlines was reconfigured routes and making improvements in capacity and utilization to reach the expected efficiency and offer better service to the general public. Indeed security had a great impact on the demand of airlines. After attack of 9/11 domestic passengers demand went down by more than 30 percent, which caused a reduction on routes and numbers of flights not to mention that planes were grounded and thousands of workers were laid off. To rebuild the public confidence in the air transportation, both airlines and government started working together. These security measures have managed to allay the public fear. According to Bisignani, â€Å" Despite severe shocks in recent years-including the attacks of Sept. 11, 2001, and outbreaks of avian flu-the demand for air travel is at record levels and is expected to grow an average of 6 percent each year for the foreseeable future. People need to fly. More important, people want to fly†. ( Bisignani,200 6) The peak in oil prices during 2008 and the financial crisis during 2009 affected and slowed down the numbers of passengers ,specially leisure travelers, as the prices of oil pushed up fares, and people’s disposable income decreased. The demand for business travel also shifted left. The industry responded with fiercely competing on the airfare which resulted in huge revenue losses and forced major airlines like American Airlines to be restructured. The airline industry overcame this crisis due to people’s need to fly for business and personal purposes and due to the absence of any other alternate mode of long-distance transportation. The use of substitutes such car, train diminishes with distance travelled. This demonstrates that the demand for air transportation is inelastic for longer flights and for business purposes. The lack of substitutes let the airline industry to move without a real external competitor, the passenger trains, bus and personal automobiles are not a viable option for traveling long distances and for business travel. In addition for leisure purposes the demand is more elastic because travelers are more likely to change destination or postpone trips expecting lower ticket prices. Despite the events of security breaches, wars and the economy, the demand for air flight has increased and is expected to continue increasing. The airlines continue to compete among themselves with pricing and offering complementary goods such hospitality, policies, car rental, hotels and tourist packages as the opportunities to improve their sales. Cost structure In the airlines industry, fixed costs are high, while variable costs tend to be low. Costs are fixed and variable at different points in time. That is, the timeframe in this market is important to categorize cost on their relation to output. With the commoditization of air travel, cost structure is now a key success factor in the industry. Central cost items are fuel, capital and wage costs. Costs in fuel prices, which are exogenous as is the time series for the average fuel efficiency of planes; constant dollar amount per seat mile that grows at the rate indicated by the Producer Price Index; and wages, which are based on several factors, such as inflation, industry margins, and average worker tenure. Concerning wages, they are fixed costs in short term decisions and variable in the longer term, where total wage costs change in relation to volume of activity as a result of recruitment, retirement, and dismissals. Consequently, effective management of fuel, maintenance, and labor cos ts is mandatory in the current environment in this industry (Harmsen, 2007). Fixed costs are costs that are unaffected by changes in volume. These costs are always constant even when production varies. One example of fixed cost is rent of premises. In the extremely short term, all costs are fixed, while all costs may be regarded as variable in the very long term, which will be described later, in this section. A good example to illustrate could be long-term leasing aircraft leasing contracts. In the short run the airline would be unable to avoid these payments no matter how it adjusts output. Therefore, lease payment is a fixed cost in the short run, but in the long run they are variable, because contractual obligations will expire (Vasigh, Fleming, & Tacker, 2008). Variable costs are costs that increase or decrease with fluctuations in production. In the aviation market, infrastructure, wear, and the bulk of the fuel are often placed in the variable cost bracket. These normal variable costs are then adjusted by the eï ¬â‚¬ect of congestion, since large load factors add costs from increased services, cancellations, and many other sources. As mentioned on the fore above, costs in the airlines industry are fixed and variable at different points in time. For the purpose of pricing, for instance, a cost structure is required that expresses the time horizon at which different cost categories may be considered fixed and variable. We will describe them with at least three different time spans: medium-long term, short term, and very short term, as follows. * Medium-long term: once the schedule is in place, the costs of operating air services are relatively fixed. This means that capital costs for aircraft, pilots’ wages, technical staff and other skilled labor cannot be influenced. * Short-term: once the carrier decides to embark on the flight, all costs under the medium-long term heading become fixed as do the costs for infrastructure charges (except passenger service charges), wear and the bulk of the fuel. * Very short term: the costs for ticketing, food, travel agency commissions, and extra fuel consumption due to the advent of an extra passenger become fixed once the carrier has decided to accept a ticket reservation. Moreover, wage, capital, and fuel costs are decided to a great extent in markets where it may reasonably be assumed that a single carrier has little influence over prices. Experience shows, however, that major carriers are able to influence all the above costs through negotiation. It is very difficult to observers outside the airline industry to assess the extent of these potential negotiating gains. Analysis of Competitive Forces (Porter’s five forces) The threat of entry by new competitors The threat of entry by new competitors in the Airline Industry is moderate. Being a capital intensive industry, new entrants would require large amounts of money. However, with easy access to bank loans and credit the likelihood of new airlines entering the market has risen. There are still a lot of barriers to entry in the industry. Higher Oil prices would require the airline to operate at full capacity to be profitable and smaller airports do not provide sufficient passenger traffic. New entrants would also have difficulty getting gates at the airports which major airlines use as their hubs. This acts as a barrier for them to operate on more lucrative routes. Major airlines also have stronger brand recognition and have garnered customer loyalty through their frequent flyer programs. Skybus Airlines, Independence Air, ATA Airlines and Maxjet Airways are among the most recent examples of new entrants that have failed to survive in the industry. Even Virgin America, the most successful of new carriers, has so far failed to turn a profit since entering the market 5 years ago. So while entering the new market might be easy, success stories such as that of Southwest & AirTran & JetBlue have been far and few. Pressure from substitute products The pressure from substitute products is weak for the American airline industry. Air travel being the fastest way to travel from one origin to another has no true substitute. Lack of extensive and long distance public transportation system within US reduces the likelihood of someone taking a train or bus to their destinations. Furthermore, time consumption and convenience would also discourage customers to take these options or to drive themselves.However emerging technologies could, in a long run, generate viable substitutes. For instance, more and more companies adopting video-conferencing could impact business travel for meetings and discussions. People could opt for using online chat to virtually meet with their friends and family instead of spending large amounts of money on airline travel. The intensity of rivalry among existing competitor Airline industry is highly competitive as there are several airlines operating on the same routes. These airlines compete by trying to differentiate themselves from others by providing different services – low-fares, frequent flyer membership privileges, no baggage fee, no cancellation fee etc. Competition between the majors and the low-cost carriers has resulted in a downward pressure on the fares, benefiting the travelers but at the same time lowering the revenue for the airlines (see figure). This combined with lower demand and excess capacity has lead to a consolidation trend in the industry. Recent consolidations include – United & Continental, Delta & Northwest and Southwest & Airtran. Such consolidations could lead to monopolization of a market where the majors already rule the roost. The Bargaining power of buyers The buyers are the passengers, for either business or leisure purposes. In the aviation market, the bargaining power of buyers is quite low. The power that airline customers have varies based on the options available to them and the origin-destination city pair. Even though there are high costs involved with switching airplanes, there is not much ability to compete on service. For instance, the seat in one airline is probably not more comfortable than another, unless a potential buyer is analyzing a luxury liner. Other macro environmental trends are the weather, which is variable and unpredictable, and may shut down airports and cancel flights; and airport capacities. Hence, there are pockets where some airlines have pricing power. In this case, the overall airline industry is characterized by significant buyer power stemming from the intense price competition among airlines (Sundaresa, 2009). Since the concentration and size of the buyers in the airlines industry is relatively lower than the number of suppliers it is not difficult to observe that buyers are more aware of the price, product, and services and discounts available at their disposal. The bargaining Power of Supplier The three major inputs for the airline industry are airplanes, labor and fuel. In terms of suppliers of commercial airplanes there are three major Air Bus, Boeing and McDonnell Douglas, it seems like this few suppliers will have great power in the industry but instead they compete between themselves developing technology, capacity of passengers, mechanics training and giving solutions to improve cost effective exploitation of airplanes between others. The second input is labor such as pilots, mechanics, ground personnel and flight attendants , in general they are unionized playing a critical role in the industry. According to IATA â€Å"About half of all workers in the air transportation industry are unionized, 49.3% of workers being union members and 51.6% being covered by collective bargaining agreements in 2006† (http://www.iata.org/whatwedo/Documents/economics/Hirsch_Unions_Wages.pdf) The fuel is an important variable due to the price and its volatility but the market has many suppliers that compete to sell large volumes of fuel but they do not control the price because it is an external factor. (Hirsch, 2007) Conclusion The growth in the airlines industry shows no signs of slowing. The recent industry-wide shakedown will have far-reaching effects on the industry’s trend towards expanding domestic and international services. Despite the events of security breaches, wars and the economy, the demand for air flight is expected to continue increasing. The airlines continue to compete among themselves with pricing and offering complementary goods such hospitality, policies, car rental, hotels and tourist packages as the opportunity to improve their sales. The industry’s challenges for the 21st century are the rising costs of fuel, labor, maintenance and security, the impact of technology, such as telecommunication and video conferencing, as well as bankruptcies and shutdowns. However, the overall perspective of demand has been consistently increasing. Growth rates are not consistent in all regions, but countries with a deregulated airline industry have more competition and greater pricing fr eedom. This results in lower fares and sometimes dramatic spurts in traffic growth. Moreover, in the aviation market, consolidation is a trend. Airline groupings may consist of limited bilateral partnerships, long-term, multi-faceted alliances between carriers, equity arrangements, mergers, or takeovers. In summary, the perspectives for the airline industry are bright and it also holds many challenges. Macro-external environment may directly affect is profitability and operation. Low cost airlines have radically altered the nature of competition within the industry. For low cost, the airlines companies should continue maintaining the existing business model by reducing the cost to improve their product. Turning a profit in a competitive industry with high fixed costs isn’t about gouging consumers on baggage fees. Rather, it’s about paying careful attention to numerous behind-the-scenes expenses, and looking for opportunities to charge passengers for optional extras while keepi ng ticket prices low.

(Lowry, page 174) This shows that Jonas is actually cares for more people than from his family unit. Jonas has actually changed very much over time. There is a theme revealed while reading throughout the whole book; choices are important. When the elders have chosen not to even have color this shows that they re afraid to lose control, the want mind-controlled freaks. Its better to have even little choices like this to show some difference in the community. Taking away choices to keep from bad ones takes away good choices. Their Jobs are even chosen, so their futures are even chosen for them, so basically a planned future on a random stranger they barely know. Choices are important. Love is a probable statement, is it real? Jonas begins as a clueless and static character and blossoms into a great influence and has exposed a very important theme; choices are all on you.

Use of Thematic Maps in Geography

Use of Thematic Maps in Geography A thematic map emphasizes a theme or topic, such as the average distribution of rainfall in an area. Theyre different from general reference maps because they dont just show natural and manmade features such as rivers, cities, political subdivisions, and highways. If these items appear on a thematic map, theyre reference points to enhance ones understanding of the maps theme and purpose. Normally, thematic maps use coastlines, city locations, and political boundaries as their basis. The maps theme is then layered onto this base map via different mapping programs and technologies such as geographic information systems (GIS). History Thematic maps didnt develop until the mid-17th century, because accurate base maps didnt exist before then. Once maps became accurate enough to correctly display coastlines, cities, and other boundaries, the first thematic maps were created. In 1686, for example, English astronomer Edmond Halley developed a star chart and published the first meteorological chart using base maps as his reference in an article he wrote about trade winds. In 1701, Halley published the first chart to show lines of magnetic variation,  a thematic map that later became useful in navigation. Halleys maps were largely used for navigation and study of the physical environment. In 1854, London doctor John Snow created the first thematic map used for problem analysis when he mapped choleras spread throughout the city. He began with a base map of Londons neighborhoods that included streets and water pump locations. He then mapped locations where people had died from cholera on that base map and found that the deaths clustered around one pump. He determined that the water coming from the pump was the cause of cholera. The first map of Paris showing population density was developed by Louis-Leger Vauthier, a French engineer. It used isolines (lines connecting points of equal value) to show population distribution throughout the city. He is believed to have been the first to use isolines to display a theme that didnt have to do with physical geography. Audiences and Sources The most significant factor to consider when designing thematic maps is the maps audience, which helps determine what items should be included on the map as reference points in addition to the theme. A map being made for a political scientist, for example, would need to show political boundaries, whereas one for a biologist might need contours showing elevation. The sources of thematic maps data are also important. Cartographers must find accurate, recent, reliable sources of information on a wide range of subjects, from environmental features to demographic data, to make the best possible maps. Once accurate data is found, there are various ways to use that data that must be considered with the maps theme. Univariate mapping deals with only one type of data and looks at the occurrence of one type of event. This process would be good for mapping a locations rainfall. Bivariate data mapping shows the distribution of two data sets and models their correlations, such as rainfall amounts relative to elevation. Multivariate data mapping, which uses two or more data sets, could look at rainfall, elevation, and the amount of vegetation relative to both, for example. Types of Thematic Maps Although cartographers can use data sets in different ways to create thematic maps, five thematic mapping techniques are used most often: The most common is the choropleth map, which portrays quantitative data as a color and can show density, percent, average value, or quantity of an event within a geographic area. Sequential colors represent increasing or decreasing positive or negative data values. Normally, each color also represents a range of values.Proportional or graduated symbols are used in another type of map to represent data associated with locations, such as cities. Data is displayed on these maps with proportionally sized symbols to show differences in occurrences. Circles are most often used, but squares and other geometric shapes are also suitable. The most common way to size these symbols is to make their areas proportional to the values to be depicted using mapping or drawing software.Another thematic map, the isarithmic or contour map, uses isolines to depict continuous values such as precipitation levels. These maps also can display three-dimensional values, such as elevation, on topographic maps. G enerally, data for isarithmic maps is gathered via measurable points (e.g. weather stations) or is collected by area (e.g. tons of corn per acre by county). Isarithmic maps also follow the basic rule that there are high and low sides in relation to the isoline. For example, in elevation, if the isoline is 500 feet, then one side must be higher than 500 feet and one side must be lower. A dot map, another type of thematic map, uses dots to show the presence of a theme and display a spatial pattern. A dot can represent one unit or several, depending on what is being depicted.Finally, dasymetric mapping is a complex variation on the choropleth map that uses statistics and additional information to combine areas with similar values instead of using the administrative boundaries common in a simple choropleth map.

Psychology - Essay Example This model of memory remained under extensive research in the following years. The physical growth in size of cerebrum and the number of functions associated with this evolved cerebrum demonstrates an important step in the evolutionary ladder of natural life. Memory is one of the very complicated functions of complex life forms and this complexity reaches its maximum when Homo sapiens are analyzed. Atkinson-Shiffrin model of memory is an attempt to explain the various processes of memory which continue to operate in our brains. The first level of memory is identified as sensory memory. No matter which kind of stimulus is applied to the various senses of the body, the form of information that is delivered to the central nervous system is in the form of electrical impulse or the so called ‘nerve impulse’. For the purpose of translation of external stimuli, a number of receptors are present in the body, that continuously receive impulses in the form of vibration, sound, pressure, light and so on. These impulses are translated into electrical nerve impulses by their respective receptors and are then delivered to the brain as electrical signals. This sensory memory has a very short life span and it persists for only a few seconds i.e 2-3 seconds. The stage between sensory memory and long term memory is called short term memory. Certain chunks of information from sensory memory are shifted to short term memory which is also called working memory because the information stored there needs further processing. Short term memory easily fades away as soon as attention is drawn to any other matter; it lasts for only 18 to 20 seconds unless the information is rehearsed. Any information that is not lost after 18 to 20 seconds is transferred to long term memory. The capacity of short-term memory is limited and it is for this reason that only a small amount of information can be retained in short-term memory

The Neighbourhood 2002 - Essay Example In selecting suitable areas, their research work included personal knowledge, maps, census, and data that indicated depravity in different areas. In order to understand the potential boundaries of different areas they went on a tour and studied the neighborhood for their public space, shopping facilities and so on, in order to understand the nature of the areas that facilitated interaction between people as well as the areas of disorder. They chose two affluent neighborhoods on the fringe of the city- the boundaries of the Edinburgh neighborhood had low- rise housing flats and semi- detached private dwellings. In the case of Glasgow, playing fields acted as a sort of â€Å"buffer zone that separated the neighborhoods. Five key sections took part in the interviews – secondary school teachers, community police, councilors, youth group representatives and community councilors. These interviews were designed in such a way in order to study the social connections between the different neighborhoods. Baumgartner used the term â€Å"champions† to describe the outside agencies that took part in the interview and wondered if they would be of any use.In the affluent areas, crime and disorder such as property crime, environmental degradation and disturbances involving young people seemed to be the main concerns. On the other hand, serious crime and disorder in the deprived areas seemed to run rampant. Community spirit was perceived to be greater in the affluent neighborhoods than the deprived areas where there was less trust in their neighbors.The neighborly interaction was limited as residents would help in an emergency, but would prefer to keep to themselves otherwise.Findings revealed the va rying perceptions of the neighborhood by its residents. Whilst there are pockets of disturbances our findings reflect that perception of crime partially involves people reacting differently to similar phenomena (Hope, 1998). The people of the deprived areas feel that they are more exposed to serious crime and this, in turn, reflects the nature of community relationship enjoyed by their respective residents.

Film analysis - Essay Example The entire narrative was shocking for its sheer violence and horror but more than this, and for the purposes of this essay, The Exorcist presented an accurate and detailed depiction of demonic possession and the Catholic ritual of exorcism. Demonic possessions, according to the available literature, have a particular set of symptoms although they are not necessarily all present in any given case. These, wrote Walters (2004) for example, include insomnia, aimless wandering, compulsively eating strange or repulsive substances (or else refusing to eat at all), a repulsive stench, rigid muscles, unusual strength, fits of screaming and weeping, a significant change in facial features as a result of muscle contractions and violent aggression against oneself, nearby people, or objects (76). In The Exorcist, most of these were depicted: Regan speaking in a different voice, which was deep and gravelly; her, speaking in different languages; the misshapen face, which was also covered in lesions; Regan’s reaction to holy objects; the desecration of the nearby church; the death of Burke; and a number of other strange and unexplained phenomena that tormented her mother. Once the exorcism started, the priests were also faced w ith Regan’s string of obscenities, and the manifestation of strange phenomena including levitation, the seemingly independent movement of objects, Regan’s abnormally long tongue and strange bouts of vomiting. The â€Å"speech† element, wherein the demon speaks through Regan, is a particularly important aspect in exorcism. This can be seen in most parts of the possession reenactment. There was the deep and harsh voice depicted, which is scientifically explained as a result of an altered state wherein the person’s ventricular folds are used instead of the vocal chords while the speech has been generally found to have a characteristic

Cultural Competencies in Advaanced practice nurse- nurse practitioners Research Proposal

Cultural Competencies in Advaanced practice nurse- nurse practitioners - Research Proposal Example trends testify to the great need for advanced practice nurse who are competent and sensitive to care for culturally diverse populations (Canpinha, 2010). To address the idea of diverse cultures in our society, specific curriculum enhancement that focused on populations that are ethically diversified have been implemented for the nurse practitioners specialty at my university. We shall carry out a research on how effective the training program of cultural competency is in this institution. The process that has been used for these report include visiting clinical and community sites, identifying the curricular components at this institutions and analyzing the didactic and clinical learning experiences. The main purpose of this research was to determine how well APN are trained to give culturally competent care in practice and enhance preparation of the students to meet multifaceted needs of ethnically diverse patients, community and families. The objective of this research was to conduct a systematic review on the training of the advanced practitioners nurses on cultural competency, asses the strength of effects and quality of studies and then propose a frame work for future studies Campinha Bacote, (2010), defined cultural competence as the process in which nurses continiouly strive to achieve the ability to work with the cultural context of a patient, individual community or family from a diverse ethnic background. Kreps and Kunimoto (2002) stated that cross cultural practice is a practice that require experience and continued interest in learning and sharpening communication skills and cultural assessment. According to Eubanks, 2010, although nurses may achieve a certain degree of competence in some cultures, they cannot be totally competent in all cultures. Yet this nurses can achieve culturally competent cross cultural care when the complex combination of cultural awareness, knowledge, skills and attitude are used dynamically for the cultural assessment of

Harvard Case Study Essay Example | Topics and Well Written Essays - 1500 words

Harvard Case Study - Essay Example Additionally to the continuous conflicts with her supervisors, Lisa has not been given the chance to participate equally in the development of projects in the design of which she had a crucial role (Keyton 95). Instead, she feels that she has no chance of developing her skills – a fact that seems quite logical taking into consideration the behaviour of her supervisors towards her. As the first year within the organization has passed for Lisa, the following issue needs to be addressed: since the chances for professional development of Lisa in the specific organization seem to be limited, alternative plans of action need to be developed. Lisa should consider her leaving from the organization and her return to Right-Away – at least this would be the most appropriate solution for Lisa having in mind the challenges that Lisa has to face on a daily basis in her current position. The identification of the reasons of the problem would help to suggest a series of measures that L isa could take before deciding to leave the firm. After examining the events described in the case study it is made clear that the particular problem is related with a series of facts: a) Lisa was not adequately prepared for her position in Houseworld’s Home Care Division; in accordance with the case study Lisa was not offered particular training before being hired in the specific position; rather, she just visited the firm twice and was informed on certain issues related to the prospects of employees within the particular organization. The problem regarding the lack of recognition of Lisa’s skills seems to begin at this point. Even if Lisa was told that she would have the chance to be promoted in accordance with her skills, she was hired in a position which was rather inappropriate for her – taking into consideration her professional experience and her background – it should be noted at this point that in her previous firm Lisa was offered the position o f the director of market, a position which is clearly differentiated from the assistant product manager position which Lisa currently holds; perhaps, the problem would have been avoided if Lisa had met with her boss before her hiring in the particular organization; if the dialogue between her and Mrs. Linton had held before the hiring of Lisa in Houseworld’s Home Care Division, Lisa would have thought for a second time her decision to leave her job in Right-Away; b) both her boss, Mrs. Linton, and the associate product manager, Mr Scoville, avoid recognizing the efforts of Lisa within the organization; their close relationship – as another employee informed Lisa – would result to problems for Lisa in case she would decide to discuss with Mrs. Linton the challenges she has to face daily because of the negative comments that Mr. Scoville addresses to her on a daily basis, c) Lisa had not worked in this organization in the past; she is not aware of the organization al culture and practices – referring especially to the nature of the tasks in which the employees of its job position are obligated to be involved – as noted to her by Mrs. Linton; in other words, the problems of communication that Lisa has within the organization may be related to her lack of knowledge on the organizational ethics and practices. The above assumption could be verified by the following fact: in Right Away Lisa felt very comfortable

Instructional Coherency and School Improvement Research Paper

Instructional Coherency and School Improvement - Research Paper Example This research will begin with the statement that a compelling schooling system does not depend only on educators who are technically proficient, appropriate school curriculum, and the provision of other associated school facilities. Many kinds of research into the subject of school reforms and improvement have focused on the significance of organizational characteristics, governmental policies, leadership values, and student- teacher learning processes, all of which are considered in the modern times, as important for achieving a high-quality education. A supportive organizational environment, strong leadership, combined with technical reforms within teaching methods and school curriculum, is most likely to be of optimal benefit for the students. In the present efforts to elevate the standards of the high schools in U.S., there have been various forms of reforms, ranging from an increase in course exigency to guaranteeing competency standards of the educators. Some of the schools, on the other hand, have removed the passing grade standard of Ds and focused on simpler courses and vocational tracks to facilitate learning. The various State education departments, in turn, have raised the number of credits necessary for the core content subjects, created a standard for the content, while introducing standardized test patterns. Besides these various reforms brought in to elevate the levels of education in the US, there has been another aspect which has been gaining prominence in the recent times: instructional program coherence.
