John Steinbeck Research Paper Example | Topics and Well Written Essays - 1250 words

John Steinbeck - Research Paper Example The lower part of the Salinas valley was a shipping center. The demographic and the geographic location characteristics of John Steinbeck’s hometown were great factors that influenced a majority of his novels and indicated his characters had a strong identification with the land. Steinbeck even wrote to George Albee in 1933 telling him that he wanted to write the story of the entire valley, all the small towns and farms and all the ranches located in the wilder hills. Steinbeck had a comfortable childhood period in Salinas, though as a teenager his family faced numerous setbacks. His adorable father who had been working as a manager in Sperry Flour lost his job. He worked out his second option of opening a grain and feeds store, but unfortunately it failed too. Eventually, he was in a position to secure a job in Monterey County as the treasurer. Steinbeck loved his pony, which he named Jill, and this inspired him to write his later novel entitled â€Å"The Red Pony†. His writing career was greatly affected by his childhood even ts. On his ninth birthday, someone gave him a copy of Thomas Malory’s work, and he admits that when he first read it, he was charmed of words because the old fashioned words delighted him (Steinbeck 97). He keenly read the stories of King Arthur, and together with his sister, they would visualize the towers of Camelot amidst the sandstone erosions alongside the Pastures of Heaven where his aunt resided. Twenty years down the line, he adopted Arthurian tropes besides chapter headings of his novel Tortilla Flat. Steinbeck in his career would travel to England to prepare how the Arthurian tales would be updated for modernity. His mission wasn’t complete until his demise but his Noble Knights and Acts of King Arthur were later published posthumously. As a teenager, John Steinbeck displayed a robust interest in writing and in his high school days, he would work until the

Evaluation of frontline the merchants of cool Essay

Evaluation of frontline the merchants of cool - Essay Example However, marketing is admittedly not that simple or easy, as consumers are quite fickle. They can change their minds readily, by following trends and whatever is considered as â€Å"cool.† Marketeers and advertising professionals can focus their efforts only on a particular sector or segment of the population, to achieve maximum effect. One can direct all marketing and advertising on middle-aged individuals, for example, for these are the people who are at the peak of their earning capabilities, at the prime of their careers. Or one can focus on youths which is also fast becoming a significant sector because of its huge spending power. Teenagers are the hottest consumer demographic today, at 33 million strong with a buying power of about $100 billion by themselves alone, and by influencing parents, can still command another $50 billion to spend. I will argue in this paper that the comparison made by media critic and professor Robert McChesney likening this population segment a s a massive empire to be colonized, an intellectual equivalent to Africa, is not very accurate. Discussion Teenagers as a separate demographic segment came into prominence only recently as family incomes rose during the last few decades. Teens today have more pocket money when compared to earlier generations due to this rising affluence brought by a good economy and a continued globalization in teen culture has a marked influence on how this sector came to the attention of professional marketeers. Teen lifestyle became a distinct marketing category that deserves all the attention from marketing and advertising professionals because teenagers' big spending power on consumer items is a crucial factor when selling items like CDs, films, television programs, clothing, jewelry, shoes, books, music, sports, and many other items. In a certain but limited sense, this is probably what Prof. McChesney referred to as a moral equivalent of the vastness of the African continent at the turn of th e previous century, when it was ripe for the taking and exploitation. The teen demographic sector provides a vast opportunity for the purveyors of youth culture, food, fashion, fun, beauty products, activities, etc. because of their huge spending power in absolute dollar terms. Teenagers in a way had become a legitimate sector as part of an American consumer polity (Lee & Zhou 102). However, the comparison of this teen demographic sector to the African continent is not very appropriate, as it is a bit of an exaggeration because of one key difference. In the time of British colonialism and imperialism, the colonized peoples of Africa were in no way able to offer some form of resistance. It was largely a one-way relationship, in which the British held all the cards, so to speak, with the African peoples in a very weak position in the relationship of colonial power and colonized people. The colonial encounter in Africa was that of inequality, the British from a position of strength and the Africans in a weak position (Asad 16) but this is clearly not the case when it comes to the teens in terms of marketing. The youth today have a voice or choice, in which they

Treatment for Tobacco Use Essay Example | Topics and Well Written Essays - 500 words

Treatment for Tobacco Use - Essay Example Chantix was developed specifically for smoking cessation and is a highly selective nicotinic acetylcholine receptor partial agonist. Chantix affects the sites in the brain that are affected by nicotine and aid by reducing the craving for nicotine. Being a partial agonist means that is has both a stimulating and a blocking effect on the receptor it is attracted to. Pfizer received a priority FDA review because of its potential to offer substantial improvement in the public health. According to the Journal of the American Medical Association (JAMA), trials took place in 2003-2004 at 6 US and 18 International medical clinics that were experienced in smoking cessation. The participants were chronic smokers who averaged smoking 21 cigarettes per day. The trials were designed as a 12-week treatment program with an extended follow-up period. Participants were given carbon monoxide testing to verify their claims of abstinence. In a trial reported by JAMA, after 52 weeks 43.6% of the participants that received varenicline had continued not to smoke. This compared to 36.9% of the participants that received a placebo. Other studies have reported a success rate of 21.9% for varenicline versus 8.4% for the placebo. The difference has been attributable to the design of the study.

Adult stem cells Essay Example | Topics and Well Written Essays - 750 words

Adult stem cells - Essay Example Stem cells are responsible for tissue or organ formation during prenatal life, and also for further growth. They are also responsible for repairing and regeneration of internal body system. This internal replenishing system works continuously throughout our life span. These cells display important attributes, which distinguishes them from normal cells. The cell division of stem cell gives rise to new stem cell or turned into specialized cell with definite function such as a muscle cell, a red blood cell, or a brain cell. In vivo or in vitro stimuli activate these cells to acquire special functions by becoming part of tissue- or organ-specific cells. Stem cells in the gut and bone marrow are at continuous task to repair and replace injured or eroded tissues, and therefore they multiply regularly by a process of cell division. In the organs like the pancreas and the heart, they are generated under certain physiologic conditions (http://stemcells.nih.gov/info/basics/basics4.asp). The ma jor breakthroughs in stem cell research will able to figure out clearly the development of an organism from a single cell. The most of the work is reported on two types of stem cells embryonic stem cells and non-embryonic stem cells. There is a recent introduction of genetically "reprogrammed" stem cell termed as induced pluripotent stem cells (iPSCs) in 2006. Stem cell therapy is administered through local delivery or systemic infusion, of autologous or allogeneic cells. This aids in restoring the viability or functioning of damaged and malfunctioned tissues (Lu, Zhang & Jin, 2009). Non-embryonic stem cells are also called as ‘adult stem cells’. They are undifferentiated cells, found throughout the body of animals and humans in differentiated tissue or organ after the embryonic growth. They are also termed as somatic stem cells which are responsible for building different specialized cell types. These cells play pivotal

Organization, timing and personal accountability Statement

Organization, timing and accountability - Personal Statement Example Lack of prioritizing will affect my career in business since I will not know when and where to concentrate my efforts. As such, this will be an obstacle in my career. Lack of priorities may make it hard for me to balance different aspects of my life. Be it social life, work life and even family life.

Celebrity endorsement in the womens fragrance market and its impact Essay

Celebrity endorsement in the womens fragrance market and its impact upon consumer behaviour - Essay Example ndary research and the findings of primary research, all of which show that celebrity endorsement does indeed appear to be effective in contributing to increased sales of products and services. Celebrity endorsement has been a common feature for many years, and is almost as common as advertising. A well known star or personality is shown in advertising as using and supporting a particular product or service, thereby imbuing the product with a degree of respectability that it may not otherwise have. By virtue of the product or service being good enough to be used by a celebrity, the idea is that consumers will be confident enough about the product to purchase it. This in turn should theoretically contribute to increased sales of the product or service, especially in the case of a product such as a fragrance, where the aura associated with the fragrance is the aura around the celebrity person. In the fragrance market in particular, there are several instances where the popularity of a particular brand of perfume and the reputation associated with it have been enhanced through the association with the image of a particular celebrity. Some examples are the Chance brand of the Chanel perfume company, which has long been associated with Nicole Kidman, a well known movie star. The fragrance has become characteristic of the elegance and timeless, classic beauty that the actress symbolizes and this has ratcheted up the sales of the product considerably. It must be noted however, that such celebrity endorsement involves a considerable investment because a substantial sum needs to be paid to a celebrity in order to encourage them to come forward to endorse a product. If such investments in advertising expenses are to be justified, they need to be backed up with an adequate level of sales to match. This research study proposes to examine the psychology behind the effectiveness of celebrity endorsement and whether or not it is effective in contributing to increased volumes
