Creating a Business Idea free essay sample
Idea Recently the United States government has released funds for creating small businesses. An opportunity to acquire government funding for a business venture is one to take advantage of and to put dreams into reality. The intent of this paper is to outline the three main forms of business organizations including the tax and legal implications as well as the accounting requirements for each structure. In addition, this paper proposes creating a small business of a womenââ¬â¢s only gym while weighing in the advantages and disadvantages of the three types of business organizations which are sole proprietorship, partnership, and corporation. To start the process of forming a business there are three main forms of business organizations that a potential small business owner must choose from. Three of the main business organizations used in the market place today includes sole proprietorship, partnership, and corporation. Deciding on a business structure appropriate for a new business will have long-term impacts and it is crucial to weigh all the choices. The following must be considered: the desired level of control, tax implications, risk of lawsuits, and the level of personal liability (Kimmel, Weygandt, Kieso, 2009). Reviewing available options and selecting an appropriate form of business organization is the first step to creating a successful company. Before determining the preferred type of organization for the womenââ¬â¢s gym, here is an outline of the key attributes of each form. A sole proprietorship is a business owned by one person (Kimmel, Weygandt, Kieso, 2009). An advantage of sole proprietorship is it is simple to establish and gives the owner control over the business (Kimmel, Weygandt, Kieso, 2009). This is always a great advantage for someone who wants to open a business because it gives them leeway to run their business however they choose. In addition to advantages, a sole proprietorship does have its disadvantages. A sole proprietor is personally liable for debts of the business (Kimmel, Weygandt, Kieso, 2009). In other words, the owner is risking his or her personal assets to liquidation if the business is not successful. A partnership is owned by two or more individuals and has shared control over the business (Kimmel, Weygandt, Kieso, 2009). This is a great advantage because partners can bring their own unique skills and resources into the business. The partners should formalize their duties and contributions in a written partnership agreement (Kimmel, Weygandt, Kieso, 2009). This agreement states who does what in the business and also how much money each of the partners put into the new business. It is sometimes common for one partner to put in more money than the other as well. Like a sole proprietorship, all partners are personally liable for debts of the business (Kimmel, Weygandt, Kieso, 2009). If the business is not successful then the partners are liable for the money or assets they put into the partnership agreement. A corporation is much different than a sole proprietorship and partnership. A corporation is a business organized as a separate legal entity owned by stockholders (Kimmel, Weygandt, Kieso, 2009). An investor in a corporation would receive shares of stock to indicate ownership in the company (Kimmel, Weygandt, Kieso, 2009). This means that the investors are stockholders in the corporation and own part of the company. An advantage of a corporation business organization is that buying stock is often more attractive than investing in a partnership because shares of stock are easy to sell or easy to transfer ownership (Kimmel, Weygandt, Kieso, 2009). Therefore, it is easier for corporations to raise funds and become more successful in the end (Kimmel, Weygandt, Kieso, 2009). A corporation has no personal liability but it does have some disadvantages when it comes to taxes and legal implications. It is important for a small business, no matter what the business organization, to communicate with its internal and external users. Creditors, investors, and management need to know what the business owes and owns and looks at the businessââ¬â¢ four different financial statements which are the balance sheet, income statement, retained earnings statement, and statement of cash flows. These four financial statements are considered the backbone of financial accounting and show special significance, but ultimately, each has one common goal: to show internal and external users where the money is in the company. No matter what form of business organization the small business is they all need to prepare these four financial statements. The income statement deals with the revenues and expenses a company incurs for a period of time (Kimmel, Weygandt, Kieso, 2009). This financial statement reports the success or failure of the companyââ¬â¢s operating and non-operating activities. The retained earnings statement shows the amounts and causes of changes in retained earnings during the period (Kimmel, Weygandt, Kieso, 2009). This statement brings together the beginning and ending retained earnings for the period, using information such as net income from the companyââ¬â¢s other financial statements. A companyââ¬â¢s balance sheet reports assets and claims to assets at a specific point in time (Kimmel, Weygandt, Kieso, 2009). In other words, the balance sheet summarizes a companyââ¬â¢s assets, liabilities, and stockholderââ¬â¢s equity. These three segments give investors, creditors, and managers an idea as to what the company owns and owes, as well as the amount invested by the shareholders. The balance sheet must, and always, follow the following formula: Assets = Liabilities + Stockholderââ¬â¢s Equity (Kimmel, Weygandt, Kieso, 2009). The fourth and final financial statement is the statement of cash flows. This is used to provide financial information about the cash receipts and cash payments of a business for a specific period of time (Kimmel, Weygandt, Kieso, 2009). Cash flow is determined by looking at three components by which cash enters and leaves a company through their operating, investing, and financing activities. No matter what type of business organization or how big or small the business is it needs to have all four of these financial statements prepared for investors, creditors, and management. The following consequences associated with each form of business organization are tax and legal implications and accounting implications such as the Sarbanes-Oxley Act (SOX) and the Financial Accounting Standards Board (FASB). These factors need to be greatly considered when deciding which organizational form to choose. If someone chooses sole proprietorship or partnership, they generally receive more favorable tax treatment than a corporation (Kimmel, Weygandt, Kieso, 2009). However, repeated again proprietors and partners are personally liable for all debts of the business; corporate stockholders are not (Kimmel, Weygandt, Kieso, 2009). It is important and ethical that every business is honest in their financial statements to investors, creditors, and their stakeholders. In 2002 Congress passes the Sarbanes-Oxley Act (SOX) to reduce unethical corporate behavior and decrease the likelihood of future corporate scandals (Kimmel, Weygandt, Kieso, 2009). This act prevents businesses from embellishing on what they own or owe on their financial statements and to give investors more confidence in corporate accounting. In 1973, FASB was established to create and improve standards of financial accounting and reporting that foster financial reporting by nongovernmental entities that provides decision-useful information to investors and other users of financial reports (Financial Accounting Standards Board, 2012). To accomplish the mission, the application of comprehensive and independent processes encourages broad participation, objectively deem to all stakeholdersââ¬â¢ views, and focus on the oversight by the Financial Accounting Foundationââ¬â¢s Board of Trustees (Financial Accounting Standards Board, 2012). These standards are very important to the efficient functioning of the economy and internationally. Having more and more businesses be international only intensifies the importance of SOX and FASB to have international comparability with all financial statements. The hypothetical small business will be a womenââ¬â¢s only gym. This gym will be a safe haven for all women who are self conscious or just feel more comfortable exercising in a gym where there are no men around. In this women only gym, they would be more likely to give and receive open advice on their health condition and their workout plan. With women trainers, females could likely get better advice as well as have options for activities that may not be available in co-ed gyms. The overall goal of this women only gym is to allow females to exercise in a safe and non stereotypical environment to help them have healthy lives. The choice of business organization form for this gym is a partnership. The reason for this is to allow two or more people, women of course, to be involved in this business adventure and put forth their own unique skills and resources. There is no need for this company to be a corporation because it is meant to be operated in a small town and the partners of this women only gym will have enough money to start it up without stockholders. Many future business owners jump into decisions without proper deliberation and research. If you do not consider the benefits and liabilities of each business form it can be costly. There are many risks and factors in starting a business but if the owner knows the capital requirements of the business, government restrictions, and personal liability then they will most likely choose the right business form to help their business expand and be successful in the future.

Information Technology in the Tourism-Free-Samples for Students
Question: Discuss about the use of Information Technology in the Tourism and Hospitality Industries. Answer: Introduction It is mandatory for tourism and hospitality industries to adopt new technologies to compete favorably with business rivals. The companies must design new distribution models to cope up with environmental changes. A sustainable information management system should ensure coordination of Information Technology, processes and managing information. Reports have it that in tourism and hospitality industries, information technology applies in three ways; guest services, management information and operational areas (Benckendorf, 2014). Application of Information Technology has given rise to new services including; interactive video texts and online brochures. The major impact of technology in the tourism and hospitality industries is in the distribution and marketing sectors. However, less attention is paid to areas that are human-intensive such as supplier-consumer and guest-host relationships. The main types of technologies applied in the tourism and hospitality industries include; mobile communication, the internet, computer and reservation systems. With advancement in technology, the tourism and hospitality companies can communicate with travelers through devices such as mobile phones and tablets. Different companies may opt for different forms of communications for example email, GPS tagging or text messages. According to Zeng (2014), through the internet, travelers are able to have a reconnaissance by visiting the companies websites where photos of location are availed which gives them of a clue of their plan destination. Computer systems are used by tourism and hospitality companies to connect their branches and allow easier communication between staff and customers. Through computer systems, the company can gather information about guest preferences and experience. The reservation systems which are mainly booking engines enable the travelers to make a price comparison and also reservations. Some of the available booking engines within the industry that are online include the Expedia and Orbitz. Neuhofer (2014) eludes that through booking engines, tourism and hospitality companies incur low costs by regulating their purchasing processes and call volume. A significant transformation in the tourism and travel industries is evident with improvement in information technology which incorporates sustainable offline and online services. Through Information Technology, some travel companies use e-commerce websites to help travelers in accessing information about the available reservation systems. According to Law (2014), the clients can choose their travel destination since the information available is of high quality and diversity. Mobile technologies have also been applied in the travel industries for access and booking of various options in travel is made easier for the clients using their mobile devices like tablets. In a nutshell, the synergy between the travel industry and information technology is necessary since the specific travel destination of a client is achieved and also travel services solution. Leung (2013) denotes that the purchase decision of customers intending to buy tourism commodities is determined by the nature of the companys website. To gain customers preference, the website must be easier to access. A successful website can be developed by first having a clear understanding of various perceptions by the customers. A comparison study showed that international tourists are more sophisticated than domestic tourists in their choice on what products to purchase (Xiang, 2015). The customers perception is based on; house-keeping, room-size, and front-desk services. A similar study showed that customers from China were more likely to rely on electronic word-of-mouth rather than hotel branding in online reservations. Modern advancements in Information Technology have made the internet preferable for tourists to research and plan for their travel. Take for instance the IPK which is an internet travel monitor based in Europe. A survey conducted on this monitor system showed those two years after its development, 26 percent of people had started using it. However, 74 percent of the population did not access the internet monitor system. According to Xiang (2015), the major internet travel sites are; E-booking and E-travel by destination. A survey showed that Germany registered the highest number of internet travel-bookings. France and Spain are the leading countries in E-travel concerning market share. On the other hand, USA leads in E-travel concerning destinations. Zeng (2014) asserts that online information search ranking is influenced by the foll owing factors; demographic, contextual and psychological. It is also crucial to consider the type of source information available for the tourist. The extent of available information is also a factor to consider. Conclusion In this paper, the efficacy of Information Technology in the tourism and hospitality industries is evident. Websites designed by companies help in marketing themselves. It is important for managers to consider issues relating to Information Technology and incorporate Information Technology in line with the achievement of set goals and overall mission of the business.

Current Concept And Machanisms In The Pathogenesis Of Atherosclerosis Essay Example
Current Concept And Machanisms In The Pathogenesis Of Atherosclerosis Paper Atherosclerosis is the leading cause of death and disability in the developed world. Despite our familiarity with the disease, some of its fundamental characteristics remain poorly recognized and understood. Although many generalized or systemic risk factors predispose to its development, atherosclerosis affects various regions of the circulation preferentially and yields distinct clinical manifestations depending on the particular circulatory bed affected. Atherosclerosis of the coronary arteries commonly causes myocardial infarction and angina pectoris. Atherosclerosis of the arteries supplying the central nervous system frequently provokes strokes and transient cerebral ischemia. In the peripheral circulation, atherosclerosis causes intermittent claudication and gangrene and can jeopardize limb viability. Involvement of the splanchnic circulation can cause mesenteric ischemia. Atherosclerosis can affect the kidneys either directly (e. g. , renal artery stenosis) or as a frequent site of atheroembolic disease. Even with in a given arterial bed, atherosclerosis tends to occur focally, typically in certain predisposed regions. In the coronary circulation, for example, the proximal left anterior descending coronary artery exhibits a particular predilection for developing atherosclerotic occlusive disease. Likewise atherosclerosis preferentially affects the proximal portions of the renal arteries and in the extracranial circulation to the brain, the carotid bifurcation.

Not all manifestations of atherosclerosis result from stenotic, occlusive disease. Ectasia and development of aneurismal disease, for example, frequently occur in the aorta. The mechanisms that underlie this discontinuous anatomic distribution of atherosclerosis remain uncertain. (Rodney A. White, White A. , Ramadan Shaafi, White A. White, 1989) Atherosclerosis manifests itself focally not only in space, as just described, but in time as well. Atherogenesis in humans typically occurs over a period of many years, usually many decades. Growth of atherosclerotic plaques probably does not occur in a smooth linear fashion, but rather discontinuously, with periods of relative quiescence punctuated by periods of rapid evolution. After a generally prolonged silent period, atherosclerosis may become clinically manifest. The clinical expressions of atherosclerosis may be chronic, as in the development of stable, effort-induced angina pectoris or of predictable and reproducible intermittent claudication. Alternatively, a much more dramatic acute clinical event such as myocardial infarction, a cerebrovascular accident, or sudden cardiac death may first herald the presence of atherosclerosis. Other individuals may never experience clinical manifestations of arterial disease despite the presence of widespread atherosclerosis demonstrated post mortem. INITIATION OF ATHEROSCLEROSIS FATTY STREAK FORMATION An integrated view of experimental results in animal and study of human atherosclerosis suggests that the fatty streak represents the initial lesion of atherosclerosis. The formation of these early lesions of atherosclerosis most often seems to arise from focal increases in the content of lipo-protein within regions of the intima. These accumulations of lipoprotein particles may not result simply from an increased permeability or leakiness of the over lining endothelium. Rather this lipoprotein may collect in the intima of arteries because they bind to constituent of the extracellular matrix, increasing the residence time of the lipid- rich particles within the arterial wall. Lipoproteins that accumulate in the extra cellular space of the intima of arteries often associate with proteoglycan molecules of the arterial extracellular matrix, an interaction that may promote the retention of lipoproteins by binding them and slowing their egress from the intima. (James S. C. Gilchrist, Paramjit S. (EDT) Tappia, Thomas (EDT) Netticadan, 2003) Lipoprotein particles in the extracellular space of the intima particularly those born to matrix macromolecules, may undergo chemical modification. Accumulating evidence supports a pathogenic role for such modifications of lipoproteins in atherogenesis. Two types of such alterations in lipoproteins bear particular interest in the context of understanding how risk factors actually promote atherogenesis: oxidation and nonenzymatic glycation. Lipoprotein Oxidation Lipoprotein sequested from plasma antioxidants in the extracellular space of the intima become susceptible to oxidative modification. Oxidatively modified low density lipoprotein (LDL), rather than being defined homogerous entity, actually comprises a variable and incompletely defined mixture. Both the lipid and protein moieties of these particles cab participate in oxidative modification. Modifications of the lipids may include formation of hydroperoxides, lysophospholipids, oxysterols, and aldehydic breakdown products of fatty acids. Modifications of the apoprotein moieties may include breaks in the peptide backbone as well as derivatization of certain amino acid residues. A more recently recognized modification may result from local hypochlorous acid production by inflammatory cells within the plaques, giving rise to chlorinated species such as chlorotyrosyl moieties. Considerable evidence supports the presence of such oxidation products in atherosclerotic lesions. Nonenzymatic Glycation In diabetic patients with sustained hyperglycemia, nonenzymatic glycation of apolipoproteins and other arterial proteins likely occurs that may alter their function and propensity to accelerate atherogenesis. A good deal of experimental work suggests that both oxidatively modified and glycated lipoproteins or their constituents can contribute to many of the subsequent cellular events of lesion development. LEUKOCYTE RECRUITMENT After the accumulation of extracellular lipids, recruitment of leukocyte occurs as a second step in the formation of the fatty streak. The white blood cells types typically found in the evolving atheroma include primarily cells of the mononuclear lineage; monocytes and lymphocytes. A number of adhesion molecules or receptor for leukocyte expressed on the surface of the arterial endothelial cell likely participitate in the recruitment of leukocyte to the nascent fatty streak. Constituent of oxidatively modified LDL can augment expression of leukocyte adhesion molecule. This example of illustrate how the accumulation of lipoprotein in the arterial intima may link mechanistically with leukocyte recruitment and subsequent events in the lesion formation. (Pierre-Jean Touboul, J. R. Crouse, 1997) Laminar shear forces such as those encountered in most regions of normal artery can also suppress of the expression of leukocyte adhesion, example branch points often have disturbed laminar flow. Ordered laminar shear of normal blood flow augments the production of nitric oxide by endothelial cells. This molecule in addition to its vasodilator properties can act at the low levels constitutively produced by arterial endothelium as a local anti-inflammatory autacoid, for example limiting local adhesion molecule expression. These examples indicate how hemodynamic forces may influence the cellular that underlie atherosclerotic lesion initiation and provide a potential explanation for the local distribution of atherosclerotic lesions at certain sites predetermined by altered flow pattern. Once adherent to the surface of the surface of the arterial endothelial cell via interaction with adhesion receptors, the monocytes and lymphocytes penetrates the endothelial layer and take out residence in the intima in addition to products of modified lipoprotein, cytokines can regulate the expression of adhesion molecules involved in the leukocyte recruitment. For example, the cytokines interlukin one (IL-1) or tumor necrosis factor alpha (TNF-alpha) induce or augment the expression of leukocyte adhesion molecules on endothelial cells. Because modified lipoprotein can induce cytokines release from vascular wall cells, this pathway may provide an additional link between accumulation and modification of lipoprotein and leukocyte recruitment. The directed migration of leukocyte into the arterial wall may also result from the action of modified lipoprotein. For example, oxidized LDL may promote the chemotaxis of leukocyte. Also, oxidatively modified lipoprotein can elicit the production by vascular wall cells of chemoattractant cytokines such as monocytes chemoattractant protein-1. (Frank Kessel, Patricia L. Rosenfield, Norman B. Anderson, 2003) FOAM CELL FORMATION Once resident within the intima the mononuclear phagocyte differentiate into macrophages and transform into lipid-laden foam cells. The conversion of mononuclear phagocytes into foam cells requires the uptake of lipoprotein particles by receptomediated endocytosis. One might suppose that the well recognized classical receptor for LDL mediated the lipid uptake. Patients or animals lacking effective LDL receptors due to genetic alterations however have abundant arterial lesions and extraarterial xanthomata rich in macrophage derived foam cells. Also the exogenous cholesterol suppresses expression of the LDL receptor, such that under hypercholesterolemic conditions the level of this cell surface receptor for LDL decreased. Candidates for alternative receptors that can mediate lipid-loading of foam cells include a growing number of macrophage scavenger receptors, which preferentially endocytose modified lipoproteins and other receptors for oxidized LDL or beta-VLDL (very low density lipoprotein) a type of lipoprotein commonly encountered in certain hypercholerterolemic states. By ingesting lipids from the extracellular space the mononuclear phagocytes bearing such scavenger receptors may remove lipoproteins from the developing lesion. Some lipid loaded macrophages may leave the artery wall, functioning to clear lipid from the artery. Lipid accumulation and hence propensity to form atheroma, ensues if the amount of lipid entering the artery wall exceeds that exported by mononuclear phagocytes or other pathways. Macrophages may thus play a vital role in the dynamic economy of lipid accumulation in the arterial wall during atherogenesis. Some lipid laden foam cells within the expanding intimal lesion perish. Some foam cells may die as a result of programmed cell death known as apoptosis. This death of mononuclear phagocytes results in formation of the lipid rich center often called necrotic core, of more complicated atherosclerotic plaques. (Shari R. Waldstein, Merrill E Elias, 2001) Macrophages taking up modified lipoproteins much like intrinsic vascular wall cells may elaborate cytokines and growth factors that can further signal some of the cellular events in lesion complication. A number of growth factors or cytokines elaborated by mononuclear phagocytes can stimulate smooth-muscle cell proliferation and production of extracellular matrix, which accumulates in atherosclerotic plaques. Cytokines found in the plaque including IL-1 or TNF ââ¬â alpha can induce local production of growth factors such as forms of platelet derived growth factor (PDGF), fibroblast growth factor and others that may contribute to plaque evolution and complication. Other cytokines, notably interferon gamma (IFN-gamma) derived from activated T cells within lesions can inhibit smooth muscle proliferation and synthesis of interstitial forms of collagen. These examples illustrate how atherogenesis likely depends on a complex balance between mediators that can promote lesion formation and other pathways that can mitigate the atherogenic process. (Aron Wolfe Siegman, Timothy W. Smith, 1994) FACTORS THAT MODULATE INHIBITATION OF ATHEROMA Elaboration of small molecules by activated mononuclear phagocytes and vascular wall cells in the evolving lesion may also modulate atherogenesis. Notably reactive oxygen species can modulate growth of smooth muscle cells, activate inflammatory gene expression via the nuclear factor kappa beta (NFk beta) transcriptional control system and annihilate NO radicals, decreasing the effect of this endogenous vasodilator. However macrophage in the lesion may be activated to express the inducible form of the enzyme that can synthesize NO, known as inducible NO synthase. This high capacity form of the enzyme can produce relatively large, potentially cytotoxic amounts of No radicals. While at the low concentrations of NO produced by the constitutive NO synthase in endothelial cells, this radical may produce beneficial effects; when overproduced by activated phagocytes, however it may prove deleterious. Export by phagocytes may constitute one response to local lipid overload in the evolving lesion. Another mechanism, reverse cholesterol transport mediated by high density lipoproteins (HDL), may provide an independent pathway for lipid removal from atheroma. This transfer of cholesterol from the cell to HDL particle involves specialized cell surface molecules such as the ATP binding cassette transporter (ABCA1) (the gene mutated in tangier disease, a condition characterized by very low HDL levels) and a family of scavenger receptors (the B family). Such reverse cholesterol transport explains part of HDLââ¬â¢s antiatherogenic action. (Richard O. Cannon, Julio A. Panza, 1999) Although clear evidence supports lipoprotein disorder as predisposing factors for atheroma formation, other etiologies may contribute to or modulate atherogenesis. For example hypertension constitutes an independent risk factor for coronary events. Male gender and the postmenopausal state also augment the risk of developing coronary artery disease. Premenopausal women have increased HDL levels compared to age matched men. However a favorable lipoprotein pattern only partially accounts for the protection against atherosclerosis conferred by the premenopausal state. Although laboratory studies suggest that estrogens have direct beneficial effects on the arterial wall, clinical trials have not shown that estrogen replacement therapy prevents recurrent myocardial infarction in postmenopausal women. Indeed treatment with a combination of estrogen and progesterone appears to augment cardiovascular events in women with or without prior myocardial infarction. (Susan Wilansky, James T. Willerson, 2002) Diabetes mellitus aggravates atherogenesis. In addition to the well known microvascular complications of diabetes, macrovascular disease such as atherosclerosis causes a great deal of excess mortality in the diabetic population. Diabetes associated dyslipidemias strongly promote atherogenesis. In particular the constellation of insulin resistance, high triglycerides and low HDL often in association with the central adiposity and hypertension frequently seen in type 2 diabetic patients, seems to accelerate atherogenesis potently. As noted above hyperglycemia may promote the nonenzymatic glycation of LDL, LDL modified in this manner, like oxidatively modified LDL, may signal many of the initial events in atherogenesis. Triglyceriderich lipoprotein particles often elevated in poorly controlled diabetic patients also accentuate atherogenesis. Lp(a) (often pronounced lipoprotein little a to distinguish it from apolipoprotein AI and others found in HDL) provides a potential link between hemostasis and blood lipids. The Lp(a) particle consists of an apoprotein (a) molecule bound by a sulfhydryl link to the apolipoprotein B moiety of an LDL particle. Apoprotein (a) has homology with plasminogen and may inhibit fibrinolysis by competing with plasminogen. Other risk factors for atherosclerosis related to blood clotting include elevated levels of fibrinogen or of the inhibitor of fibrinolysis, plasminogen ââ¬â activator inhibitor 1 (PAI-1). Another nonlipid risk factor for coronary events, elevated levels of homocysteine, may act by promoting thrombosis, although the pathophysiology of this association is uncertain at present. Although individuals with marked elevations of Lp(a) or homocysteine do appear to have heightened risk of coronary thrombosis, in the population at large these factors show a much weaker correlation with vascular events than LDL, HDL, or the global inflammatory marker C-reactive protein (CRP). (Philip M. McCabe, Neil Schneiderman, Tiffany Field, A. Rodney Wellens, 2002) The relationship between tobacco use and atherosclerosis also remains poorly understood. The rapid reduction in risk for cardiac events after cessation of cigarette smoking implies that tobacco may promote thrombosis or some other determinant of plaque stability as well as contribute to the evolution of the atherosclerotic lesion itself. For example tobacco smokers have elevated fibrinogen levels a variable associated with increased atherosclerosis and acute cardiovascular events. INFLAMMATION In other situations, antecedent inflammatory states may predispose toward atherosclerosis. For example Kawasaki disease in childhood may promote developments of vascular lesions in the arteries of adults. Infectious agents continue to be proposed as instigators or potentiators of atherogenesis. However in humans atherogenic role for vital or microbial pathogens remains speculative. In some patients immune or autoimmune reactions may contribute to atherogenesis. In the particular example of the accelerated form of coronary arteriopathy that plagues heart transplant recipients, immunologic factors may contribute importantly to the pathogenesis. (James Shepherd, Sheperd and Gaw, Allan Gaw, 2001) Known monogenic defects in lipoprotein metabolism account for only a fraction of the familial risk for coronary artery disease. Thus other as yet undefined and perhaps multiple genetic factors may contribute to coronary risk. Mechanisms of disease susceptibility involving the arterial wall might account for some of the genetic predisposition to atherosclerosis unexplained by lipoprotein disorders. Application of molecular genetic techniques may identify new polymorphisms linked to coronary risk and may eventually shed light on new pathophysiologic mechanisms. For example some data suggest a link between certain alleles of the genes encoding angiotensin converting enzyme, the cytokine lymphotoxin, or PAI-1 with increased risk of myocardial infarction. Application of genomic technologies may aid identification of modifier genes that modulate individual responses to established risk factors. Large studies currently in progress should clarify these and other potential genetic factors that influence atherosclerosis. REFERENCES: Aron Wolfe Siegman, Timothy W. Smith, 1994.

The Leader of South Africa essays
The Leader of South Africa essays To be a great leader there are a lot of things that one needs to possess. Having business skills along with political and civic means are some of the ways to be established as a leader. Taking control and guiding your people through trials and tribulations shows many characteristics of leading.

Personal Reflection Paper Essay Example | Topics and Well Written Essays - 1000 words - 1
Personal Reflection Paper - Essay Example I was able to change my thinking from having goals of childish nature to a more mature outlook on life. The activity gave me an opportunity to compare my life goals with those of my classmates. This is critical in terms of comparing me with other like-minded and equally intellectual formidable classmates. This comparison showed me that despite my ambitious nature in terms of my life goals, there are others who are more ambitious and aggressive. It was a revelation and a challenge for me to work harder and be more ambitious in order to compete on the same level with my intellectual equals. As the exercise proceeded, I was able to reevaluate my life goals and coalesce them with a more realistic and tangible future. The defining moment for the entire exercise was the peer review section where classmates were tasked with evaluating each otherââ¬â¢s life goals. The result of this activity was that my teammates gave me the second highest score in the entire class. It was a defining moment for me in terms of not just my self-esteem but also my general outlook on life. This event truly gave me an opportunity to evaluate and reevaluate my life goals.

R Sennett The Corrosion of Character. The personal consequences of work in the new capitalism. Norton 1999 - Essay Example There is no argument that change is sometimes good although often it disrupts peopleââ¬â¢s lives and may be traumatic. The bone of contention with sociologist Richard Sennett is that change and especially technological advances is the root cause of workerââ¬â¢s woes and the source of injuries to and corrosion of character. It has transformed the capitalist economy into a new form of ââ¬Å"flexible capitalismâ⬠or what Sennett calls ââ¬Å"New Economyâ⬠which is less concerned about interpersonal relationships. In Sennetts words it is ââ¬Å"a regime which provides human beings no deep reasons to care about one anotherâ⬠(1999, 148).

This in turn according to Sennett has brought injuries to employees as well as corroded their character as now they are unable to make a coherent narrative of their lives or build their identity around work. This essay will explore Sennettââ¬â¢s work The Corrosion of Character: The personal Consequences of Work in the New Capitalism to gain an insight as to how new ways of working injures and corrodes character and, whether it has made employees disposable and precarious workers and causes and consequences of such work in the modern corporation.
