Performance Enhancing Drugs Essay Example | Topics and Well Written Essays - 500 words

Performance Enhancing Drugs - Essay Example Performance enhancing drug tests are stricter for male than for female athletes. There is a list of substances banned in males only. Differences between the reporting level for men and women are also acknowledged. The confusion over the nandrolone issue is exacerbated by claims that low concentrations of metabolites conferred no performance -enhancing effect and are due to the contamination of supplements. This conclusion from a single untimed urine sample could not be substantiated; the possibility that the result arose from the long-term use by injection of nandrolone may seem unlikely in the present climate of testing but evidence to the contrary had to be unequivocal (Dean, 2000). The number of positive test results has increased dramatically in recent years, but still, researcher admit that differences in male and female constitution prevent laboratories to identify illicit substances. OTC drugs, such as ephedrine and pseudoephedrine, are relatively less potent and non-selective than other stimulants, hence their availability without prescription. Following Bowers (1997) this lack of selectivity, with a concomitant likelihood of side-effects, especially if used in supratherapeutic doses, makes them less desirable as potential performance -enhancing drugs, since no improvement in performance has been found in the few research studies on these drugs. Another argument is that women may have illnesses that require them to take particular drugs. It indicates an increasing trend in its use as a performance -enhancing drug, since its pharmacological properties are likely to have adverse, rather than positive, effects on performance in most sports. Statistical results prove that women swimmers perform much better than men because of inadequate drug tests and differences between male and female constitution.

Mobile Technology in Organizations Essay Example | Topics and Well Written Essays - 1500 words

Mobile Technology in Organizations - Essay Example Different ways have come up where an individual can have a discussion with another who is miles away (Huang, et al., 91). Change in technology has led to introduction of mobile phones as a means of communication. Many organizations in the society have opted in using mobile phones as means of communication. This paper discusses in depth the optimistic impacts of the use of mobile technology in business. Mobile technology refers to various types of cellular communication technology devices. These devices include palmtop computers, net-book computers, smart phones, which are the most common, global positioning devices, and wireless debit or credit cards. In most cases, mobile devices may greatly alter business transactions (Unhelkar, 27). For instance, mobile technological devices entail new ways of management, invention, and innovation of new products, and how service is given to customers. Mobile technology has subsequently enabled individuals to have extensive tours all over the worl d with no fear of business management. Moreover, staff that work away from their business locations benefit immensely from the use of mobile phones. Smart phones are not only used for communication but also serve a wide range of functions such as business transactions and research. ... Over years, usage of mobile technology has boomed and technology that is strictly for a particular business has been developed. Businesses have devised their own software where they can carry out business transactions. Moreover, businesses are able to solve quite a range of problems using mobile technology. The level of technology is one essential factor that people consider before purchasing any device. Apart from the ultimate goal of targeting customers, businesses use mobile technology to simplify their office operations and advance planning and organization. The impact of mobile technology on business economy has been highly optimistic (Simon, 157). Mobile technology has been a force that clears away barriers, promotes inclusiveness, and opens opportunities to all those who would otherwise not partake in the digital cost-cutting measures. Arguably, the use of mobile technology devices has enabled businesses worldwide to come up with strategies of solving their problems. The explo sion and expansion of mobile technology has benefited businesses, improved efficiency, streamlined processes, and enabled completely new businesses (Barnes and Scornavacca, 126). Mobile technology devices as depicted by scholars will in the new future take place of desktops. This is because businesses each passing day keep on inventing mobile software platforms that enhance the mode of information delivery and change the operation systems of both the businesses and customers. The most significant benefit that arises from the use of mobile technology in businesses is accessibility. As depicted by Simon (151), mobile technology enables a whole network of employees or offices in an organization to carry out business transactions no matter where they are

Cars Safety Essay Example | Topics and Well Written Essays - 5000 words

Cars Safety - Essay Example That is because people today are too lazy to even put some energy in braking, and automobile companies are responding to it. The development of brakes from manual to power brakes, and from two-wheeler to four-wheeler brakes makes that obvious. The brake system of a standard car consists of disc brakes as well as drum brakes. Disc brakes comprise of a metal disc that rotates with the wheel, and two brake pads gripped in calipers facing the disc. When the break pedal is pressed, hydraulic fluid forces the pads to rub against the disc, thus stopping the disc from rotation. Drum brakes comprise of a metal cylinder that revolves with the wheel, and two brake shoes. The shoes are curved pieces of metal lined with friction material made of asbestos or some other material that can resist the heat generated by the friction. When the break pedal is pressed, the hydraulic fluid forces the shoes on the drum, and the friction helps the wheel to stop. This complex setup of brakes makes it very easy for the driver to stop the car; thus, any error in this system is a major cause of life-taking accidents. (MacVicar; Wyatt, Vol.2, 570-571, 1990) Another important safety feature in an automobile is airbags. Today, almost every saloon car has at least four airbags provided for the passengers. It saves lives yes, but some people think they are more of a headache. They are those who hit their cars quite often and the airbag pops out even on the slightest bump. It emerges out of the steering wheel or the doors whenever the car is hit hard enough to cause an injury. It was a milestone in car safety when launched properly in 1998, but had some drawbacks that appeared later. The airbag is made of nylon and is filled with nitrogen gas on collision. When the car is hit, crash sensors activate the inflator that fills the bag with nitrogen immediately deploying it. Although they are a lifesaver in major accidents, they have been known to easily injure the passenger. The speed with which it is deployed can be responsible for injury to the passenger's facial features like breakage of the nose or trauma to the eye due to spectacles. This makes the airbag a drawback in situations where it pops out on slight hits. In addition, it can be harmful to children and old people. Thus, the passengers should be seated as far away from the airbag deployment area as possible, and the river should point it towards his chest instead of the head. Moreover, the use of seatbelt is mandatory for the airbag to serve its full purpose. (Brain, 2000) Excellent car suspension is a very important feature for safe driving as it keeps the car in the driver's control. Precisely, it increases the road grip of the car thus maximizing the steering stability as well as comforts the passengers with shock absorbers. The absence of perfectly flat roads makes suspensions necessary to prevent passengers from jumping continuously inside the vehicle, and for stable driving, especially cornering at high speeds. The now vastly available power steering makes it easier to turn the wheels while shock absorbers make a mountain feel like silk. (Harris, 2005) Tires play a vital role in increasing road grip of the car as well as comforting the passengers. Tires with proper grip are mandatory for the car to run smoothly. Loss of grip can be a cause of major accidents. It can easily be

Current Events and U.S. Diplomacy - Essay Example As such, he declared that the United States would not send its troops to assist its allies in maintaining peace and stability in their nations. However, he decreed that he would give weapons, as well as, ant other military support to these nations, especially those fighting against communist rule, such as the Peoples Republic of Vietnam. In addition, he ordered a massive number of American troops stationed in foreign countries to return home, whilst strengthening the military power and stability of their governments to enable self-rule after the departure of American troops (Ambrose, 1989). The diplomatic relationship between the United States and the Republic of Vietnam was gross and appalling. The United States and the Vietnamese were at war. In fact, this war claimed over half a million of American troops stationed in Vietnam to maintain peace and establish a stable government. Many of the US soldiers died in military camps as prisoners of war, while numerous other sustained serious physical injuries before they got a reprieve through the call back plan initiated through Nixon’s Doctrines. This angered many citizens against Nixon’s regime. However, the move adopted by President Nixon to pull back American troops from Vietnam, a process termed as Vietnamisation, helped in restoring the public’s trust in his regime. While pulling out the American troops, the president provided the Vietnam government with skills, tools and weaponry, as well as, necessary financial support to set up a strong military squad in their country. This quest was very succe ssful as it enabled the two countries restore cordial relationships, and maintained peace and stability. The president also got local approval from his citizens for his successful efforts of saving numerous American soldiers (Dallek, 2007). The diplomacy rule adopted by President Nixon enabled establishment of peace and harmony within the Southeast Asia. The triple effects of this move also

Philosophy Essay Example | Topics and Well Written Essays - 2500 words - 4

Philosophy - Essay Example This is due to change in the human behavior that has taken place. Crime is mostly committed by the youth. Youth is now very conscious of the different types of crimes that can be conducted and the way it can be executed. This information is easily accessible due to the technology that has advanced at a very fast pace. Thus to combat crimes and have a society where people can live without fear, where they can live with dignity, education has become important. Education refers to formal system that teaches them how to conduct their lives in a decent manner; how to interact and react with others in the society. It is found that youth has been deprived of formal education as there are numerous barriers. It is also recognized that education alone can bring about a harmonious society, a community that would think of the welfare of others before their own self. Thus it is essential to understand what these barriers are and how they can be overcome so that the youth is not deprived of educat ion. Youth is the period of transition from childhood to adulthood and they are tossed from one state to another either because of the compulsion to abide by the norms of the society or because they undergo a mental turmoil themselves. Youth has been defined by UNESCO (2004) as persons between the age of 15 and 25. They are consistently unstable and are undergoing the period of evolution. This is precisely the age when they need the right guidance and direction how to conduct their lives. They are full of vigor and energy but they reel under the agony of indecision. Youth is a period when they have to acquire new tools to become part of the workforce and assume responsibilities in the world (Soares, 2000). The transition into adult life is a process of complex socialization with multiple influences and transfers (Pais, 2000). Accrued experience of the past assist in transition to adulthood added to which are the aspirations and plans for the future. The youth’s

Social Model of Disability Essay Example | Topics and Well Written Essays - 4000 words

Social Model of Disability - Essay Example It has multi-dimensional concept with both objective and subjective characteristics. Interpreted as an illness or impairment, Disability can be seen as fixed in an individual's body or mind. Whereas interpreted as a social context, Disability can be seen in terms of the socio-economic, cultural and political disadvantages resulting from an individual's exclusion by the non-disabled society he/she is in. Different stakeholders like persons with disabilities; Social advocacy groups, Medical practitioners, Social workers and the General public all have a different view of disability. And the meaning of Disability has evolved over the years through various perspectives such as a moral perspective, a medical perspective as well as social and human rights perspectives. The core definition of the British social model comes in the UPIAS document, Fundamental Principles of Disability. Let me quote from an edited version of the document reprinted in Oliver (1996), " In our view, it is society, which disables physically impaired people. Disability is something imposed on top of our impairments by the way we are unnecessarily isolated and excluded from full participation in society. Disabled people are therefore an oppressed group in society. To understand this it is necessary to grasp the distinction between the physical impairment and the social situation, called 'disability', of people with such impairment. Thus we define impairment as lacking all or part of a limb, or having a defective limb, organism or mechanism of the body and disability as the disadvantage or restriction of activity caused by a contemporary social organization which takes little or no account of people who have physical impairments and thus excludes them from participation in th e mainstream of social activities." (Oliver, 1996, 22). The British social model contains several key elements. It claims that disabled people are an oppressed social group. It distinguishes between the impairments that people have, and the oppression, which they experience. And most importantly, it defines 'disability' as the social oppression, not the form of impairment. The Social approach to Disability has its roots in British history. The social model is much more developed in UK. It has been called 'the big idea' by the British disability movement (Hasler, 1993). Developed in the 1970s by activists in the Union of the Physically Impaired Against Segregation (UPIAS), it was given academic credibility via the work of Vic Finkelstein (1980, 1981), Colin Barnes (1991) and particularly Mike Oliver (1990, 1996). The social model has now become the ideological litmus test of disability politics in Britain, used by the disabled people's movement to distinguish between organizations, policies,

Practitioner Values in Dementia - Portfolio 1 Essay

Practitioner Values in Dementia - Portfolio 1 - Essay Example 1). It will also look at values and government legislations as ethical basis for healthcare. People with dementia are losing their memory, especially those that are aging (US National Library of Medicine, 2012, p. 1). The dysfunction in their brain has serious effect to their memory and their ability to communicate. Though this illness is common among elderly, but this is not normal for all of those that are aging (US National Library of Medicine, 2012, p. 1). Whitehouse,  Price,  Struble,  Clark,  Coyle,  and Delon (1982) explained memory loss of patient with dementia and Alzheimer based on evidences indicating that the nucleus basalis of Meynert, a distinct population of basal forebrain neurons, is the source of cholinergic innervation of the cerebral cortex (pp. 1237-1239). Post-mortem research illustrated the profound reduction in the presynaptic markers for cholinergic neurons in the cortex of patients with Alzheimer's disease and senile dementia of the Alzheimer's typ e (Whitehouse et al., 1982, pp. 1237-1239). Research further bared that memory loss is associated to that neurons of the nucleus basalis of Meynert which undergo a profound and selective degeneration at more than 75% in these patients and provide a pathological substrate of the cholinergic deficiency in their brains (Whitehouse et al., 1982, pp. 1237-1239). Demonstration of selective degeneration of such neurons represents the first documentation of a loss of a transmitter-specific neuronal population in a major disorder of higher cortical function and, as such, points to a critical subcortical lesion in Alzheimer's patients (Whitehouse et al., 1982, pp. 1237-1239). Recent analysis of the National Institute on Aging (NIA), involving representative sample of Health and Retirement Study (HRS), bared that health care for people with dementia have increasing emotional and physical demands (Vaughn, 2013, p. 1). Thus, add to the financial burden for care. It also inspires the National Hea lth Institute to find effective treatment for Alzheimer’s disease and dementia, too (Vaughn, 2013, p. 1). Through NAPA, health expert established and enforced National Plan to Address Alzheimer’s Disease the institution also capitalized on research and development of BRAIN initiative, with the support of the president, to generate approaches to broaden our understanding on the neurological disorders, inclusive of neurological disorders and Alzheimer (Vaughn, 2013, p. 1). Dementia is an illness that could be genetically inherited by offspring from their elders or parents. Alzheimer is considered as the worst form of dementia which may appear at 65 years of age or further (Alzheimers.org, 2013b, p. 1). Hence, health practitioners call this a familial disease. Vascular and fronto-temporal dementias are other forms of dementia (Alzheimers.org, 2013b, p. 1). The first can be developed by high cholesterol levels in their bodies. Other milder forms of dementia which can be de tected at an earlier age are dementia with Lewy bodies, Down’s syndrome, and Huntington’s disease (Alzheimers.org, 2013b, p. 1) Medical experts admitted difficulty in determining the cost of dementia care, both in formal and informal setting, because majority of those who suffered in this illness has also multiple medical
