Globalization & Public Health essays

Globalization & Public Health essays Globalization is commonly defined as the worldwide integration of economies in the face of substantially increased transborder trade and investment [1]. It is generally addressed in the context of economics and information technologies. Globalization has brought wealth and modernity to many of the worlds peoples. Frequently overlooked in the classroom, unfortunately, are the new vulnerabilities now exposed by globalization, including the spread of natural disease and the use of disease as possible instruments of terror. It is important to understand how globalization may be affecting global public health policies, and what implications that has for global control of infectious diseases. From a public health point of view, it is imperative that we bear in mind that infectious diseases do not recognize borders, as evidenced by the current HIV/AIDS pandemic. The two main results of globalization have been expanding international travel and increased trade. Increased trade includes the exporting and importing of foodstuffs, which are probable carriers of pathogenic microbes. Some fresh foods may be contaminated during picking, packaging, transport, or delivery [2]. Another factor that may facilitate the international spread of food borne disease is the centralized processing of human and animal foods, followed by widespread distribution. For example, if a component of animal feed is contaminated with a pathogen, a food animal could ingest the pathogen. This food animal could then pass the pathogen to anyone who consumes a part of the animal which could cause a global outbreak. Increased international travel, a result of globalization, is also a major cause of the spread of disease, and also a major factor in the threat of bioterrorism. Examples of disease spread from continent to continent include HIV/AIDS, tuberculosis, malaria, West Nile encephalitis, Vibrio cholerae, coccidioidomycosis, influenza, measles, and ...

Moment Generating Function for Binomial Distribution

Moment Generating Function for Binomial Distribution The mean and the variance of a random variable X with a binomial probability distribution can be difficult to calculate directly. Although it can be clear what needs to be done in using the definition of the expected value of X and X2, the actual execution of these steps is a tricky juggling of algebra and summations. An alternate way to determine the mean and variance of a binomial distribution is to use the moment generating function for X. Binomial Random Variable Start with the random variable X and describe the probability distribution more specifically. Perform n independent Bernoulli trials, each of which has probability of success p and probability of failure 1 - p. Thus the probability mass function is f (x) C(n , x)px(1 – p)n - x Here the term C(n , x) denotes the number of combinations of n elements taken x at a time, and x can take the values 0, 1, 2, 3, . . ., n. Moment Generating Function Use this probability mass function to obtain the moment generating function of X: M(t) ÃŽ £x 0n etxC(n,x))px(1 – p)n - x. It becomes clear that you can combine the terms with exponent of x: M(t) ÃŽ £x 0n (pet)xC(n,x))(1 – p)n - x. Furthermore, by use of the binomial formula, the above expression is simply: M(t) [(1 – p) pet]n. Calculation of the Mean In order to find the mean and variance, youll need to know both M’(0) and M’’(0). Begin by calculating your derivatives, and then evaluate each of them at t 0. You will see that the first derivative of the moment generating function is: M’(t) n(pet)[(1 – p) pet]n - 1. From this, you can calculate the mean of the probability distribution. M(0) n(pe0)[(1 – p) pe0]n - 1 np. This matches the expression that we obtained directly from the definition of the mean. Calculation of the Variance The calculation of the variance is performed in a similar manner. First, differentiate the moment generating function again, and then we evaluate this derivative at t 0. Here youll see that M’’(t) n(n - 1)(pet)2[(1 – p) pet]n - 2 n(pet)[(1 – p) pet]n - 1. To calculate the variance of this random variable you need to find M’’(t). Here you have M’’(0) n(n - 1)p2 np. The variance ÏÆ'2 of your distribution is ÏÆ'2 M’’(0) – [M’(0)]2 n(n - 1)p2 np - (np)2 np(1 - p). Although this method is somewhat involved, it is not as complicated as calculating the mean and variance directly from the probability mass function.

Marketing Law and Ethics - Essay Example Marketing has become an authority in the society. It shows people the way to become models; images they see in various advertisements. The marketer tells us; buy it, use it. They also tell us; we can buy success, happiness and love with the advertised products, service and brands so that consumer also buys the life-style with the product. The advertisements have become the role of educators and family. While watching these advertisements, consumer compares the life he is watching and his own life and finds his life ordinary and meaningless. Because of this reason, the advertisements became an imitated model ethic is known as moral values and plays a role as social rules in a society. In today's world, in marketing, through advertisements the messages are given with help of the cultural differences, social class differences; also using color differences as a tool, so it is one of the biggest arguments of ethic. The most definite dilemma of modern-day advertising is its manipulation on the individual and societal growth, significance in formation of people's values in rapidly globalizing world. At the same time, mounting globalization process grounds seriously the query about the social accountability of business need essential deliberation of long-term benefit of consumers and society as a whole. It is important to note the reciprocity of advertising technological development process and scrutinizing of human rights and standards of living in the society. In other words, transformation in one way requires immediate change in other (Harris 2001). The world of advertising, made up of advertisers, agencies, the media and the various specialized services, constitutes an environment which is in a constant state of flux; examples include new marketing and advertising techniques, changing markets, changing consumer requirements, new products, new media and a constant turnover of staff. As well as the whole commerce industry, marketing has its own ethical problems. Several marketing experts or their representatives have deliberately confirmed and implemented different activities, assertions or set of laws concerning the requirement that marketing people believe ethics regulations and values, so that they become much more responsible towards the members of society (Brassington & Pettitt 2003). Most controversial cases in the legal system are the discrimination cases which base their allegations on race, color, gender, sexual orientation,national origin and religion, age. For years the mainstream media has cleanly pushed the idea that being darker as a person of color is thought to be inferior. Discrimination has diffused onto a wider massive scale. In an undeniably capitalist society, leading marketers and entrepreneurs use subtle suggestive means to accomplish their selfish, profitable motives. As in the case of promotional campaign of the world's largest cosmetics firm, based in France, L'Oreal, which specializes in perfumes, beauty aids, and related products. The ad-campaign featuring pop-star Beyonce Knowles for this cosmetics giant shows that all is not well with the face of its promotion. The company was accused of whitening Beyonce Knowles who has been the L'Oral Paris brand ambassador since 2001. The contract signed between the cosmetics company and the singer in 2001, was worth 2.4m ($4.7m) for five years. The contract stipulated that the singer had to work 10

Famine Essay Example | Topics and Well Written Essays - 500 words

Famine - Essay Example This paper will further anayze whether famine is a seasonal happening or if it has an annual cycle, its predictability, and the steps that can be taken to prevent it,if there are any. Famine can be described as the scarcity of food on a largescale. The functional description of famine needs to include the fact that it is a natural hazard that goes on to affect humans. Without it affecting humans, the otherwise natural disaster becomes a natural hazard. It is not a disaster when the human aspect is lacking. Over time in history, incidences of famine have been experienced repeatdly, and in some regions more than others. This begs for one to view it as a seasonal happening. The seasonal nature of famines is attributed to there being certain human activities that augment the influence of drought. The likelihood of famine to be experienced in a region dependson a myriad of factors. These include the geographical location, policies governing food distribution, and human activities in a place. When these factors are all analyzed, the likelihood of a famine can be determined. The effects of famine are felt by all spheres of nature, both living and non-living. Humans, plants, animals, and even property is affected by famine. Humans are by far the most affected by famine. On the event of a famine, humans are faced by starvation, malnutrition, and cases of death are reported. People waste due to lack of food, and become emaciated. Stunted, and retarded growth are also experienced by the victims of famine. Cases of diseases are increased, as individuals grow weaker and weaker due to poor nutrition. In certain instances people start fighting for the little food available, and war may result. Plants during famine, are usually the first to die. This however, is true when the famine is due to harsh weather conditions such as drought. When the cause of the famine is other than this, plants are affected to a lesser extent. Wasting,

Self-Employed Womens Association Essay Example for Free

Self-Employed Womens Association Essay Population inflation has become a constant problem and a developing conflict for all the nations in the world especially those with such little total land gross area. Urbanization and Population growth seems to coincide because both of it has become growing concerns of the world today. Though Urbanization has the more positive side of it, there are still some who oppose this ideology. Regarding population growth, it has become one aspect of the global community that indicates such a threatening reality. The people are multiplying by the minute but the resources that keep the people alive has become more scarce through the years. The scarcity of resources to satisfy population has become blatantly damaging. The growth rate around the world is increasing every year and as seen in the worlds most populous countries such as China, India, USA, the population has been inflating due to birth and fertility rate. Answering to the problems caused by overpopulation, urbanization solutions has become one arguably reliable remedy. There are four examples of cases where a positive output was produced and was recognized in the 1996 Dubai Awards. These are the Institutionalizing of Community-Based Development in Abidjan, another was the action by the Self-Employed Womens Association (SEWA) Bank, another was the City Management in Tilburg ranging from the past, present and the future, these are samples of overcoming the challenges of population and urbanization. Urbanization can produce both negative and positive effects on communities, depending on how the leaders of these communities take advantage of it. There are possible environmental problems due to urbanization but there are also environmental benefits due to urbanization. Its like a give and take relationship for population and urbanization, the importance of how the population should be treated must coincide positively with how urbanization should be handled properly to reap benefits for the population.

Diseases :: essays papers

Diseases Diseases are any harmful change that interferes with the normal appearance, structure, or function of the body or any of its parts. Since time immemorial, disease has played a role in the history of societies. It has affected and has been affected by economic conditions, wars, and natural disasters. An epidemic of influenza that swept the globe in 1918 killed between 20 million and 40 million people. Within a few months, more than 500,000 Americans died^more than were killed during World War I (1914-1918), World War II (1939-1945), the Korean War (1950-1953), and the Vietnam War (1959-1975) combined. Diseases have diverse causes, which can be classified into two broad groups: communicable and noncommunicable. Communicable diseases can spread from one person to another and are caused by microscopic organisms that invade the body. Noncommunicable diseases are not communicated from person to person and do not have, or are not known to involve, infectious agents. Some diseases, such as the common cold, and come on suddenly and last for no more than a few weeks. Other diseases, such as arthritis, are chronic, consistent for months or years, or reoccur frequently. Every disease has certain characteristic effects on the body. Some of these effects, include fever, inflammation, pain, fatigue, dizziness, nausea, and rashes, are evident to the patient. These symptoms offer important clues that help doctors and other health care professionals make a diagnosis. Many times, the symptoms point to several possible disorders. In those cases, doctors rely on medical tests, such as blood examinations and X rays, to confirm the diagnosis. Communicable diseases are caused by microscopic organisms. Physicians refer to these disease-causing organisms as pathogens. Pathogens that infect humans include a wide variety of bacteria, viruses, fungi, protozoans, and parasitic worms. Also, it has been theorized that some proteins called prions may cause infectious diseases. Bacteria are microscopic single-celled organisms at least 1 micron long. Some bacteria species are harmless to humans, many are beneficial. But some are pathogens, including those that cause cholera, diphtheria, leprosy, plague, pneumonia, strep throat, tetanus, tuberculosis, and typhoid fever. The bacteria that are harmless and live in or on you are called resident bateria. Viruses are tens or hundreds of times smaller than bacteria. They are not cellular, but consist of a core of genetic material surrounded by a protective coat of protein. Viruses are able to survive and reproduce only in the living cells of a host. Once a virus invades a living cell, it directs the cell to make new virus particles. These new viruses are released into the surrounding tissues, and seek out new cells to infect.
