Why don't cells grow indefinitely? Cells are limited in size because the outside (the cell membrane) must transport the food and oxygen to the parts inside. As a cell gets bigger, the outside is unable to keep up with the inside, and the cell membrane cannot supply the inside with what it needs to survive. Diffusion of nutrients throughout the cell also takes longer. What are 3 purposes of cell division? Growth (2) Reproduction (3) Repair What purpose does mitosis serve in the cell cycle? Equal distribution of genetic material between the two daughter cells Equal distribution of the cytoplasm and organelles between the two daughter cells (cytokinesis) Compare contrast diffusion and osmosis. Diffusion - movement of the solute from an area of high solute concentration to low concentration Osmosis - movement of water towards an area of high solute concentration Compare - both water and the solute move from areas of high concentration (water or solute) to low concentration Cancer (pp. 48-55) Define metastasis. When some of the cancerous cells break off from the primary tumour , spread through the blood and lymph and establish a secondary tumour in a new location. Describe the steps for a secondary tumour formation. Step 1: The primary tumour develops as a group of cells that are undergoing uncontrolled cell division Step 2: As the tumour gets bigger, it stimulates blood vessels to form and supply it with nutrients. Step 3: Tumour cells enter blood vessels and lymph vessels. This is dangerous because the tumour cells can move to other parts of body (metastasis). Step 4: Primary cells which arrive at new area of the body form secondary tumour s , which may eventually be fatal to the organism. How does a doctor diagnose cancer once he or she has located a tumour ? Biopsy (tissue sample) What are some reasons why cancer might recur after it has been successfully removed from a person? After surgery, a vast amount of the primary tumour is removed . H owever,

Sex Education in schools essays

Sex Education in schools essays The good news is that the teen pregnancy rate in the U.S. is the lowest its been since the early 70's, primarily due to teens increased and improved use of birth control. The bad news is that one million U.S. teens still get pregnant each year, and 78 percent of those pregnancies are unintended. The fact is that most young people in the United States begin having sex in their teens and they need honest and straightforward information about sex in order to protect themselves from unintended pregnancy. Obvious, right? Well apparently not to President Bush, who asked Congress for a 33% increase in funding for abstinence-only sex education, which would forbid teachers to talk about how contraception works or where to get it. Abstinence-only programs keep teens in the dark about sex; they have not been proven to delay or reduce sexual activity; and they fail to provide accurate information about preventing pregnancy and disease. Comprehensive sexuality education, on the other hand, teaches that sexuality is healthy, normal part of human being. It teaches students about the advantages of abstinence, while also giving them the realistic information they need about the prevention of unintended pregnancy and sexually transmitted infections. Studies show that balanced programs that promote both abstinence and safer sex are most effective and allow young people to make responsible choices. In California, teen birth rate has dropped more than 40 percent over the last decade. The credit goes to a state-sponsored program that provides information on sexual abstinence and birth control. Teen birth rate has fallen from 11th nationwide in 1991 to 21st in 2002, according to the California Wellness Foundation. California is the only state that refuses to accept federal sex-education money, which requires public schools to teach only sexual abstinence and avoid providing information on contraception ...

Outlawing the Ownership of Handguns Essay Example | Topics and Well Written Essays - 1250 words

Outlawing the Ownership of Handguns - Essay Example For Americans, any firearm represents equality and individualism. The Second Amendment to the US Constitution provides that ‘A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed’ (Rights of the People). All fifty of the United States have laws recognizing the right to bear arms as contained in the Second Amendment to the US Constitution. By virtue of the Second Amendment and the Constitutions of at least 44 US states recognize ‘the right to use arms for defense’ (The War Against Handguns). Moreover, a survey conducted by Lawrence Research in 1998 reveals that ‘by an 8:1 margin, Americans believe you have the right to use a handgun to defend yourself in your own home. By a 3:1 margin, people believe that to fight crime, getting tough with criminals is more effective than banning guns’. This trend and ideology within the American legal culture to recognize a right to armed self-defense has been criticized for many reasons. The most obvious relates to the incidents of handgun related crimes and the potential for accidental death and serious injury Professor Friedland of the University of Toronto does not feel that the protection of life, liberty or property is sufficient to justify possession of a handgun or any type of firearm. He maintains that ‘Citizens should rely on the police, security guards, and alarm systems for protection.’

Businesses and International Strategy Essay Example | Topics and Well Written Essays - 5000 words

Businesses and International Strategy - Essay Example This has made it necessary to conduct research across boundaries as it helps to identify regional and global market segments. As firms need to collect information from a broader and more diverse range of markets conducting research in developing countries has become essential. However, conducting market research in developed countries poses certain challenges. These challenges range from collecting accurate and updated data on existing behavior patterns in a cost-effective manner. Collection of data has become easier due to technological advancement but also complex at the same time. The communications infrastructure enables data collection on a much broader and diverse scale. The removal of barriers between countries, the growth of regional and global market infrastructure and the increased mobility of consumers have exerted pressure to have an integrated international marketing strategy. The emerging economies are promising in terms of sales and expansion of the multinationals and hence conducting international market research in these countries is of paramount importance. Before entering these markets, firms have to collect information to assess potential opportunities and determine how to position, price, promote and place their product. International Marketing Research (IMR) has been defined as market research conducted either simultaneously or sequentially to facilitate marketing decisions in more than one country (Kumar, 2000). The process entails taking into account various market characteristics for facilitating marketing decisions. The various components that are responsible for marketing the product can be traced. Marketing research is an important part of the marketing intelligence system as it helps to improve management decision making by providing relevant, accurate and timely (RAT) information (Aaker, Kumar & Day, 2001).

Impact of Branding on Social Class

Impact of Branding on Social Class BRANDING AND ITS IMPACT ON MIDDLE CLASS Introduction 1.1 BRAND What is a brand? The Oxford American Dictionary (1980) contains the following definition: Brand (noun): a trade mark, goods of a particular make: a mark of identification made with a hot iron, the iron used for this: a piece of burning or charred wood, (verb): to mark with a hot iron, or to label with a trade mark. A short history of brand The word ‘brand’ comes from the Old Norse ‘brandr’, meaning to burn. In pre-historic times when the initial phases of trade was coming to existence, it was by burning that early man stamped ownership on his commodity, and with the development of advanced trade of goods; buyers would use such marks (brands) as a means of distinguishing between the goods being transacted. For example a farmer with a particularly good reputation for the quality of his animals would find his brand much sought after, while the brands of farmers with a lesser reputation were to be avoided or treated with caution. Thus the utility of brands as a guide to choice was established, a role that has remained unchanged to the present day. With rapid and gradual advancement in the acknowledgement of brand for particular goods and commodity, people started vying for goods with a good reputation i.e. brand. With the elapse of time goods and brands have changed but the basic concept remains unchanged and it is ultimately brand that persuades a buyer to go for that product. And with the advanced and developed market situation, brand has become an identity not only for the company it represents but also of its customers. Brand itself has developed into a niche and people vie for that segregated population associated to that brand. Brand today holds a very specific position and top brands have today become a sense of class amongst the top notch people. People associated to a brand don’t go for the product but rather to the brand itself. And brand has set a platform to the people specially the elite class people as a way of differentiating themselves from others. But today with the financial strength of the overall population brand has become a favorite among the middle class population as well. Middle class population that focused on reliable and durable products in the past have started becoming brand conscious and the major factor for this can be the realization in part of the companies in better understanding of the market scenario of the middle class population and diversifying itself in catering to that segment of people. And in parts of the customers they have started realizing in the concept of quality over quantity. Brand established companies nowadays have started manufacturing goods and services as per the demand of these middle class people with quality goods on reasonable prices. And this has played a major role in attracting more and more people into its circle. But a major hindrance for these products and services has become cheap imitation and delicacy. From the time of establishment of brand, imitation has been found along time, so it can be justified that the practice of unlawful imitation lurked close behind, a practice that remains common till this day, even in the presence of highly developed legal systems. 1.2 SOCIAL CLASS Social class refers to a group of people with similar levels of wealth, influence, and status. Sociologists typically use three methods to determine social class. Humans have evolved living in a closed community and have thus been categorized according to their surrounding and their social identity and circle. Social class is that segmentation which varies the people according to this social status and financial stronghold. Accordingly they can be differentiated as follows: Upper class people Upper-middle class people Middle-class people Lower-middle Class People Lower Class People This segmentation according to their financial situation has been the center of attraction for marketers around the globe. Marketers focus on individual segment of people according to the product and services they serve. Some serve the niche market while many serve other general segments. But with financial increment of other class especially of the middle class, more companies serving the top class have started putting their focus on middle class people. 1.3 Objectives: General Objectives To find the importance of brand amongst general public. To identify the market scenario of branded products. Specific Objectives To analyze the trend of brand influence among the middle class population. To study the stronghold of middle class people in the space of branded goods. 1.4 SIGNIFICANCE OF STUDY Brand has come a long way with the advancement of market and the people associated to the market. Brand nowadays cannot sustain itself only by serving the elite class so the focus has been made relying on the trend and demand of the market, and accordingly their focus has been more directed towards middle class people and their demands. Another aspect of analyzing the situation can be the possibility of threat to the companies itself in trying to penetrate such a volatile segment that are still price conscious in some regards. And identifying the challenges for the brands itself and the consumers is also an important part of this study. 1.5 RESEARCH QUESTIONS Has brand become so strong that it can easily influence the price sensitive population or is it the cheap imitation that has taken over their market? 1.6 RESEARCH STATEMENT The present middle class population feels more connected to the brand they are attached to than the traditional people/ family. With more and more brands being made available at reasonable price, this segment of population has become the magnetic pull for companies that carry its significant brand. So have the companies really succeeded in luring this class of people towards itself or is it just an unsung tale of what they are yet to achieve. 1.7 LIMITATIONS OF THE STUDY Although this study has tried uncovering the areas related to brand and its impact on middle class population, total evaluation may be lagging, and the limitation for this has been mentioned below: As the cause of lack of adequate time and required information, some aspect of this study may do injustice to the overall scenario of the market. Limited number of people of this segment will be interviewed and the questionnaires filled accordingly. Some of the filled questionnaires may have doubtful results so proper information may be absent. 2. Literature Review Brand itself is not a product nor an identity put forward by an individual or a company, rather it is an instinctive feeling that individual carries about for a product or services. Trust and Gut feeling on any product is a brand. And this trust comes from meeting and beating customer’s expectation, which comes from brand values as: Price premium Customer preferences Replacement cost Stock Price and Future Earnings And the main purpose of branding is to get more people to buy more stuff for more years at a higher price. (Brand Gap: A VISUAL PRESENTATION BY MARTY NEUMEIER) And brands that catered to the top class people has successfully lured in more and more middle class population into its circle through this trust it has created amongst the total population. The penny pinching population that thrives on price subsidized products has started minimizing their quantitative expenses to focus more on brands they get attracted to. Different types of companies have different concepts of exactly what it means to be middle class. Using income level as the defining criterion for differentiation of class is reasonable. But simply judging a group by income is far from sufficient for marketers of consumer goods. Such marketers trying to reach the middle class have to know more than their salaries. They must know what makes middle class consumers tick. Income plays a powerful role in most purchasing decisions for any consumer segment, but other elements play a role that is sometimes greater than income. When products are relatively inexpensive, income has little influence on a consumer’s decision making process. Deciding to buy chocolate, for example, depends significantly more on consumers’ emotion and shopping experience—a store’s ambience, for example—than it does on how much money they make. /’Using income as the only indicator of spending habits allows much information to slip through the cracks. In addition, income is a difficult variable to act upon, in part because the data on income can be either unavailable or unreliable in most cases. Thus, companies must find meaningful alternatives to predict what consumers can afford and what they are willing to pay for certain goods and services. Zeithaml (1982, 1988) suggests in most purchasing decision customers objective is to Get the best for the money. This represents the combination of price and value orientation which is the most important consideration for most of the consumers. Crier and Ross (1997) maintains that the greater the perceived value, the greater that the customers will be interested in purchasing. They (Crier Ross) explained the term value orientation saying Consumer trends to select the lowest price alternatives when the options in the choice set are perceived to have the same level of benefit. Consumers are becoming more price conscious does not mean that they always go for the lowest price, rather they will seek for affordable price range among their acceptable quality range. Maccilil, (1987), in his study told about the total business and household consumer market that both classes consider price, quality, convenient location as the most powerful influential factors in selecting or buying consumer goods. In the same time Winklin and Duery (1987) conducted a similar study focusing on the two groups of consumers having high income and low income in USA proved the influential forces earlier described by Maccilil. In the theory of marketing and buyer behavior, the concept of social class is considered the basic determinant of consumption behavior. In fact, among behavioral scientists, there was a consensus that market behavior of individuals is closely related to their social class. In this context, social class was often considered more important than income in affecting buying behavior (Slocum and Mathews, 1970). Though these mentioned research pave a road map as to how brand influence the market of middle class people and how brand has come a long way from being a niche to being available for all in the developed nation; the basic format or the fundamentals remains the same even for developing nation like ours. And it can be concluded that of the all class of people, middle class population has become the center target for the companies to penetrate and establish itself. 2.2 THEORETICAL FRAMEWORK The dependent and independent variables are as follows: Dependent variables Sales Volume Customer Loyalty Independent Variables Availability of products at affordable prices Financial Stronghold Environment Social Up gradation 3. Research Methodology 3.1 Research Design: This research can be categorized as descriptive and observational study. This can be explained on the fact that it is based on what the trend persists on the market place and also includes facts and findings based on survey being carried out. 3.2 Population/ Sampling: Provided the fact of more brand conscious population is on the rise, this report is based only on limited sampling given the limited time period and resources. Not much study has been conducted on this topic; hence it is limited to certain aspect and does not represent the total scenario of the market. 3.3 Nature of data The source of data is categorized on two fronts: Primary Source: Interview Questionnaire Secondary Source: E-Books and magazines 3.4 Data collection technique Interview: Interview is the best and the most effective method of collecting data, because you get a firsthand knowledge about the present market scenario and the impact of what you’re searching for your study. This helps the interviewers gets to observe the intended market and its population and extract the immediate knowledge of the market. Questionnaire: Questionnaire helps the researcher to find exactly what is to be found and analyzed. A perfectly shaped set of questions gives the intended findings. It also helps to get quick results on a limited time frame. 3.5 Expected Findings Through this research I expect to understand the real market scenario of the branded products and its impact on the middle class population; their reaction towards branded goods and services and their responsiveness towards the strategies played by the companies.

Different kinds of festivals Essay

In a year we have celebrated different kinds of festivals.Sometimes,we do celebrate festivals following our religion.Different religions have different festivals to celebrate.Festival are celebrated in a grand way and gives much joy. The same thing goes for me.I am a Hindu and I celebrate many festivals.The best festival I have ever experienced is Deepavali.Deepavali comes on the month of November and it is usually on the second week of the month.Deepavali is known as the festival of lights for the Hindus. Last year,my family and I celebrated Deepavali at our grandparent’s house.After we woke up,we had to take an oil bath which was massaged from the head down to our toes.Then, we wore our new traditional clothes,dhoti and sari.We got ready to go to the temple near the house. The priest in the temple made a special offering and prayers to the God on this special day. After prayers in the temple,we went back home.A fe w minutes later,my relatives and neighbours came to our house.My grandmother served them with scrumptious traditional food.For instance,murukku,vadai,and tose.They really enjoyed their food and they said it was very tasty. Before the guest left the house,my grandfather gave them â€Å"ang pows†.I was really shocked because throughout I know only Chinese gave â€Å"ang pows† during their festival,Chinese New Year but I never knew that Indiansdid that too. Then, it was time to take our lunch.My father prepared some banana leaves to use as plates.It had really a different taste when eating from a banana leaf.It really potraits a traditional style. In the evening,we packed our things to get ready to go back home.We really missed our grandparents because they were the only ones who celebrated Deepavali in a special way. Among all the Hindu festival,I think the last Deepavali was the best festival I had ever experienced.I like the way they celebrate the festival with lighting up lights around their house.It shows that our life always brightens with ha

An Old Woman.

The poem is highly symbolic and very common placed in it's subject matter. The poet was impressed by the temple of Kandoba at Jajori and the poem is thus against this setting. â€Å"An Old Woman† is a graphic picture of a beggar woman. Having lost the promises of her past, she is reduced to her present state. As the speaker views her squarely, he, in a sort of ‘revelation', becomes aware of the decay which has set in her person and which is extended to the decaying tradition symbolized by the hills and the temples. Without using many words, the old woman forces the narrator to look at her from closed quarters.It is then that he realizes the hypocrisy of society and the decadence of the social system that has ruined the old woman to a beggar. he finds that the social fabric is destroyed, architectural features go into ruins. Human values are forgotten. The old woman's condition reduces the narrator to a small status when he feels as insignificant as that small coin in her hand. This poem humbles us to remember our responsibility to society. It reveals the callousness, a failure on our part to take care of the elderly, protect our heritage and preserve our values.In the rush of materialism and the desire to achieve, one takes all that one can from society, but giving the same back is largely forgotten. So the cracking hills, crumbling temples, crumbling of social order is directly a result of our negligence, our failure to act responsibly. Somewhere, the materialistic world has made man selfish, trapping him in a race to accumulate. When society has to face this onslaught, cracks appear, but selfish man forgets to repair the cracks, forgets to salvage lost values, thereby creating a dilapidated social fabric†¦.
