Alzheimers Disease :: Alzheimers Disease Essays

Alzheimer’s disease is a slowly progressive, degenerative disorder of the brain that eventually results in abnormal brain function and death. The disease was first described in 1907 by a German physician, Dr. Alois Alzheimer(1864-1915). In the neurological autopsy on the brain of a 56-year-old woman Auguste D., of Frankfurt, who died after several years of progressive mental deterioration marked by increasing confusion and memory loss. Taking advantage of a then-new staining technique, he noticed an odd disorganization of the nerve cells in her cerebral cortex, the part of the brain responsible for reasoning and memory. The cells were bunched up like a rope tied in knots. He termed the strange nerve bundles neurofibrillary tangles. He also noted an unexpected accumulation of cellular debris around the affected nerves, which he termed senile plaques. In a medical journal article published in 1905, Alzheimer speculated that the nerve tangles and plaques were responsible for the women’s dementia. Alzheimer’s disease is a disorder marked by a gradual decline in brain function that gets worse with time. It used to be assumed that this change was a normal part of aging that we called senility. Some people develop this condition when they are as young as 40 years of age. However, the disease is most common in persons over the age of 65. It is estimated that approximately 10 percent of persons over 65 years of age may have Alzheimer’s disease and that in persons over the age of 85, up to 50 percent may be affected. Alzheimer’s disease is not a normal part of the aging process. It is not contagious, and it is not known how it can be prevented. While the physical changes in the brain are very similar among different people the behavioral and psychological symptoms that result are complex and may differ from person to person(Kawas, 80). These symptoms lead to a form of dementia which is the loss of mental skills and abilities, including self-care capabilities. As Alzheimer’s disease progresses, these losses will result in total dependency for even the simplest activities(Erickson, 149).   Ã‚  Ã‚  Ã‚  Ã‚  Alzheimer’s disease usually comprises of three stages. The first being the onset stage. The symptoms of the onset stage often appear very gradually. There may be some minimum memory loss, particularly of recent events. The individual may experience difficulty in finding the right words to use during casual conversations. Work performance may begin to deteriorate and changes in behavior may start to become obvious.

Marxist explanations of social class inequalities Essay

In society there are many different factors which divide us and result in social inequality. In this essay, I will be covering social class. Karl Marx believed that in society, there are two major social classes, the bourgeoisie and the proletariats. The bourgeoisie are basically the upper class; in order for you to be classed as a part of them you must own the means of production such as factories etc. In order for these factories to run, they would need workers, which is where the proletariats come in. The proletariat only owns their labour force which they sell in order for a wage. Karl Marx stated that the proletariats are exploited through low pay and poor work conditions, but due to capitalism, we deal with it as were tied down to the economy. Conflict theory coined by Karl Marx suggests that suggested that social order is maintained by domination and power opposed to a shared consensus among society. This inequality is derived from social and political aspects established in s ociety. Marxists believe that social in equalities are implemented by the bourgeoisie in order to maintain a disturbance among the proletariats in order to keep them distracted from existing economic issues. A way they do this through the media. They distract the public with celebrity’s lavish lifestyles and people are tied to the economy in an attempt to imitate them. Factualists would counter this perspective claiming that social inequalities benefit society positively. They believe that it works as an incentive for individuals to work harder and achieve their maximum potential. The education system also ensures that the most suitable are picked out for the job. It also ensures that social order is maintained as people would accept their position as they had an equal chance to everyone else. Factualists also believe that the individuals at the bottom of the fragmented social scale are needed as some has to do the less attractive jobs. The New Right have a very traditional view of so ciety. They believe that women should embrace the assigned expressive role and males should be the breadwinner in the family. They have old fashioned views and are often of the Christian religion despite recent secularisation rates. The New Right are one of the few perspectives which with holds a cultural argument. They believe that failure in society is a result of the individual’s actions and choices. They believe that all the wealth within society slowly â€Å"Trickles† down to the rest of society. They believe that  business entrepreneurs create jobs for the rest of society by setting up business such as industries and factories which then create jobs; hence the wealth being distributed throughout society. Although inequalities exist and are relevant in the contemporary UK, it’s very rare that there are cases of absolute poverty due to free services provided by the government such as health care and education which then give individuals more equal life chances. Capitalism has gotten rid of many working class jobs throughout the UK such as factory jobs and mining, because of this, these working class jobs have been replaced with many middle class jobs. This has given people a better standard of living and made them more aspirational for the future. Within the past 50 years, the middle class has massively grown and become the largest social class within the UK. There are also exceptionally much more university graduates. Karl Marx was strongly against the concept of capitalism. He disliked the fact that there was income inequality. He pushed for a communist society and equality. He predicted that this would happen in the future as capitalism was unstable and was inevitable to fall. He stated that we would all achieve a class conscience and be aware of the fact that we are being exploited, realising our true value. He predicted we would all revolt against the system. The fact that we all still live in a capitalist society proves he was wrong. Sociologists such as weber countered this prediction and believed that the proletariats would be too distracted with domestic problems amongst each other forcing them to divide as opposed to sticking together.

Nutrition and food science: energy balance

Nutrition in general is a concern for adolescents, who are entering a stressful, confusing, and sometimes frightening time of social, emotional, and physical development. Healthy diet and regular physical activity help children and adults feel better, learn and work more effectively, and avoid developing a variety of risk factors for disease. The key to weight control or weight management is keeping energy intake (food) and energy output (physical activity) in balance; that is energy balance. Read also: Domestic Activities and Chemicals When you consume only as many calories as your body needs, your weight will usually remain constant. If you take in more calories than your body needs, you will put on excess fat. If you expend more energy than you take in you will burn excess fat. The relationship of energy balance to body weight can be summarized by the following equations: Energy Intake = Energy Output = Weight Maintenance Energy Intake > Energy Output = Weight Gain Energy Intake < Energy Output = Weight Loss Weight management means keeping your body weight at a healthy level. Regular exercise and a healthy diet are a must when it comes to controlling your weight. A weight management plan depends on whether you are overweight or underweight. Many people mistakenly believe that they only â€Å"burn calories† when they exercise. In fact, your body is burning calories all of the time (yes, even when sleeping!). Calories are used to keep basic body functions going, to metabolize the foods you eat, and to do any form of physical activity. Exactly how many calories people need varies, depending on such factors as gender, current body size, activity level and body weight goals a wise choice to achieve a healthy weight. A safe, tried-and-true method for long-term weight loss is to reduce calories by decreasing portion sizes when people tend to eat. When trying to lose weight or hold steady at a desired one, there’s no need to turn to the latest â€Å"diet† or outcast your favorite foods. Small changes to your diet and exercise routine can make a big difference. A healthful eating plan can include all your favorite foods if they are in reasonable amounts and balanced out with daily physical activity. Aerobic physical activity, if no health prohibitions, will assist in increasing muscle tissue and also in burning calories. However, care should be taken not to exercise more frequently and more intensely that is required for good health or to compete well. Physical activity should be balanced with diet to maintain a desired weight. Experts have come to believe that this approach of weight management is reasonable and promising. No proven side effects, however, success of weight efforts should be evaluated according to improvements in chronic disease risk factors or symptoms and by the adoption of healthy lifestyle habits, not just by the number of pounds lost/gain. But if you are over 40, have been inactive for some time, suffer from shortness of breath or weakness that interferes with daily activities, or suffer from a chronic condition, you should consult a physician before you begin any effort to reduce your weight or increase your activity level. Education may be necessary for an understanding of energy balance and basic nutrition principles. REFERENCE Atkins, R. (1981). Dr.Atkins: Nutrition breakthrough.

Computers Are Replacing More and More Jobs

Living today in the most advanced age of technologies, humans have benefited from computers. We cannot deny the fact that computers play a crucial role in the various aspects of our lives. We get a lot of help from computers and believe that computers could make people’s lives and jobs easier. But on the other hand, we forget the other fact that computers would eliminate jobs too. For example, Manufacture of all kinds of office products the computer easily does, like typewriter, adding machine, photocopier or even CD player, DVD player, and radio. In publishing, a lot of jobs are gone, many in layout and production, since computers do layout and design faster and more accurately. Even in hotel and travel industry, there have been significant losses in administration in hotels because of significant advances in the way people book and check in. Nowadays, most bookings for hotels are made through websites instead of phoning up and having your name written in a book. Additionally, management and running of a hotel can now be done all by one person. One person can have a computer with powerful hotel management software on it which can control all functions of a hotel and allocate when and where people will arrive. Moreover, as computers take over people’s jobs, social and economical problems increase. Lack of human interactions can cause social problems. People can do banking and shopping without contacting people. It will bring less bondage between people and less respect for human beings. Furthermore, there are economical problems. Even though low payment job positions disappear quickly, high payment job positions, such as high technology based job positions, are increased. The gap between these two groups will become wider. The economical unbalance can cause a lot of economical problems as well as social problems.

The Rivalry Among Existing Firms: Strong

The Rivalry among existing firms: strong The office supply industry has a large number of players with a high diversity of rivals. Competition is very furies between them because the office supply industry is so divers in product and services they provide; they include high volume office supply, warehouse clubs, online retailers, copy and print businesses, discount retailers and local and regional contract stationers. The large number of competitors in this industry, along with a lack of product differences, with low switching coast for buyers and the ability of the buyers to shop around the internet for the best price.Had made this industry growth to become very slow. source http://360. datamonitor. com/Product? pid=4CA55D31-18F9-44E1-BB86-D1E5E5306887 Rivalry Figure 9: Drivers of degree of rivalry in the office services & supplies market in the United States, 2010 Players range in size and product diversity; they include high-volume office supply providers (e. g. Staples), warehous e clubs (e. g. Costco), copy and print businesses (e. g. FedEx Office), online retailers (e. g. Amazon. com), ink cartridge specialty stores, discount retailers, as well as several local and regional contract stationers. Related article: Evaluate External Corporate CommunicationsThe large number of players, along with low-cost switching for buyers, low product differentiation, easy expansion by utilizing the internet, and poor market growth in recent years, intensifies rivalry amongst incumbents. This is ameliorated somewhat by the diversity displayed in the product portfolio of some players, such as online retailers and discount retailers, who operate in other markets and are therefore not solely reliant on the revenues generated from the office services and supplies market.Relatively low storage costs and the non-specificity of players’ assets lowers barriers to exit and eases rivalry. Overall, rivalry is strong. FIVE FORCES ANALYSIS The office services & supplies market will be analyzed taking retailers of paper, storage, stationary, and office services, such as photocopying, printing and binding as players. The key buyers will be taken as businesses, and manufacturers of paper, storage, st ationary, and equipment for photocopying, printing and binding as the key suppliers. SummaryFigure 4: Forces driving competition in the office services & supplies market in the United States, 2010 The market is highly fragmented with players ranging from multinational high-volume office supply providers to local stationers. The abundance and diversity of buyers weakens buyer power, whilst low-cost switching, low product differentiation, and high price sensitivity strengthen it. Such factors, along with low brand loyalty and easy access to suppliers and distribution, also contribute to the high likelihood of new entrants.Suppliers are numerous, and low differentiation, along with some backwards integration by players who sell their own branded goods, weakens supplier power. The large number of players, along with low-cost switching for buyers, low product differentiation, easy expansion by utilizing the internet, and poor market growth in recent years, intensifies rivalry amongst inc umbents. Buyer power Figure 5: Drivers of buyer power in the office services & supplies market in the United States, 2010 Buyers are numerous and diverse.This, along with the importance of the products and services provided by players to buyers, weakens buyer power. Buyers can range in size from sole proprietors to multinational corporations and buyer power is boosted by larger buyers with greater financial muscle. Large businesses put office services and supplies out to tender bids while smaller businesses can negotiate discounts through trade associations. However, buyer power is sustained by low customer loyalty, low switching costs, low level product differentiation and high price sensitivity, giving customers a wide choice of retailers.The internet has made cost comparison easier, raising price transparency and increasing competition. Overall, buyer power is moderate. Supplier power Figure 6: Drivers of supplier power in the office services & supplies market in the United State s, 2010 Suppliers are numerous and diverse with a large array of goods. This scale of competition from low cost economies in the Asia-Pacific places restraints on other suppliers. Players tend to have several suppliers, and this, along with low switching costs, weakens supplier power, particularly in instances where larger players have greater negotiating power.On the other hand, suppliers can offer their products to a wide range of customers, and this serves to increase their supplier power. There are elements of integration within the industry as global players sell their own branded goods. For example, Staples own branded goods represented about 23% of their sales in 2009. The lower pricing of such activities undercuts the power of other suppliers. Overall, supplier power is moderate. New entrants Figure 7: Factors influencing the likelihood of new entrants in the office services & supplies market in the United States, 2010Most office supplies are commoditized products, which hav e little brand loyalty. This, along with low enduser switching costs, little government regulation, and easy access to suppliers and distribution channels, is conducive to the entry of new players into the market. Larger players benefit from scale economies that allow them to compete with high-volume office supply providers that lead the market. Larger players with greater financial muscle would be able to negotiate better contracts with suppliers and therefore achieve better profit margins.Entry can be achieved on a smaller scale by focusing on a specific product range (e. g. an ink cartridge specialty store) or by developing an online retail shop. Poor growth in recent years, with stagnant growth forecast for the 2010-2015 period, decreases the threat of new entrants into the market somewhat. Overall, the threat of new entrants is strong. Substitutes Figure 8: Factors influencing the threat of substitutes in the office services & supplies market in the United States, 2010Many mode rn companies are taking strategies to minimize costs and the environmental impact of their operations by moving towards a paperless office format: switching costs are not excessive, as most companies have already invested in appropriate ICT systems. This, therefore, constitutes a serious challenge to those operating primarily with paper-based office products. Storage and stationary may also be influenced by switching to a paperless office format. Office services such as photocopying, printing and binding may be substituted by electronic forms of communications.Overall, the threat of substitutes is moderate. Same source Office Depot, Inc.

REGULATION, COMPLIANCE AND GOVERNANCE - Essay Example When the derivatives were distributed, it created an opportunity of basic training and helped in exploiting the difference in prices in future and spot markets. The gas trading of Enron had allowed it to be a market maker and acted as counterparty by trading on both sides and made profits as spreads between the offer and the bid price. Enron was under residual risk after it accessed both the markets and was able to overcome the same by entering into swaps and other such arrangements with dealers. As Enron owned physical plants and took charge of operating those, it had a comparative advantage over the competitors. The company was also able to protect itself from the market price movements for the same reason. Being an industry insider, it also had advantages of acquiring information needed for forecasting shocks related to particular region or sector. Therefore, besides being a market maker, Enron was also a creator of new products. The business strategy used by Enron, in 1990s, was asset light and vertical integration, after it became too leveraged due to the merger. The asset light approach indicates combination of the development of sophisticated risk management techniques with the least amount of ownership and operation of plants. Virtual integration system helps to maintain the reliability of a product with less capital investment. Enron took advantages of deregulation of the US energy markets, as later on, it can be noticed that they enjoyed the experience of steadily rising profit from merger of two utility based companies. Additionally, besides owning several gas pipelines, it also ran a natural gas as well as electricity transmission business. After 1985, Enron even started trading in gas and offered various types of derivates to interested customers, when the gas pipelines business met an end. When the derivatives

It could interpret to inability to pay bills or even worse, inability to obtain credit besides exposing the person to more destructive eventualities. 2) Although am not an expert in the field of identity theft, it is self-evident that everybody is a potential victim of such occurrences. This implies that it is necessary for all to be equipped with the appropriate information on how to deal with such modern realities. Through the exploration of some experts’ work within the field of identity theft, I am able to establish my credibility in responding to the issues surrounding identity theft. Such experts include Saleh (2013), Mulig, Smith and Stambaugh (2014), and Biegelman (2002). 2) My secondary audience will be my professor in this course as well as fellow classmates, some of whom have been victims of identity theft and who would desire greater exposure on precautionary measures to protect themselves from such future recurrences. 3) Except for some few individuals who believe there is nothing much one can do to protect themselves from identity thieves, majority of my audiences share in my school of thought that it is possible to create a wall between oneself and such fraudulent individuals. From exploration of a number of literatures, it is evident that identity theft is often a crime of opportunity, which implies that precautionary measures can go a long way in reducing risks. Most of the attacks have been made possible because of negligence and loopholes created by the victims themselves, thus they have a significant role to play in ensuring that they are safe. It is a fact that both technology and hackers
