No More Guns

If you could invent something new, what product would you develop? Use specific details to explain why this invention is needed. Nowadays, most of people really need product that made their comfort or entertainment. If I could create something, I would like to invent solar car. It has many benefits to create because if people change a general car to be a solar car, the world would have more fuel; Expense would become less; the world would become a better place. Firstly, solar car does not need a fuel. In the future, if people still drive a general car, fuel would have no to find and then it would disappear to. Hence, solar car will is becoming essential for the future. Moreover, you can use money to pay for another thing instead of refilling a fuel. Thus, money in a bank will have more and more. Then, you can have money to use when the essential time will come. Finally, pollution will be lost because solar car not need a fuel to use. Unlike a general car that made air dirty. Air will become clean. Therefore, people will have a good health. Not only are good for the people but it also made the world become a better place. From the above, it is clear that why solar car will become important for people in the future. It is not use a fuel to be energy. It is saving your money to pay other things. Lastly, it is not too dangerous for human or nature.

Aging and Disability Worksheet Essay

Part I Identify 2 or 3 issues faced by the aging population. 1 The older generations often time experience unequal treatment in the workplace and are subject to prejudice and discrimination. (Pearson, 2012) 2 Older members of society share physical differences that set them apart from the younger generations. (Pearson, 2012) 3 The aging population are involuntary included into clubs or groups determined by their age. (Pearson, 2012) Answer the following questions in 100 to 200 words each. Provide citations for all the sources you use. What is ageism? How does ageism influence the presence of diversity in society? Ageism is age based prejudice or discrimination. The effects of stereotyping on the older generations, whether intentional or not has a negative impact of diversity in society. When society determines that a person is too old to do their job or maintain their effectiveness as active members of society we are losing a great deal of experience and wisdom and inhibiting a person from doing something they may want to do. Age discrimination will have a negative impact not only on society but also on employers as they will not be able to retain knowledge and will have to pour resources into training new workers. A possible solution is to maintain an older workforce to provide mentoring and training opportunities. What is the Age Discrimination in Employment Act (ADEA)? How does the ADEA address issues for the aging population? The Age Discrimination in Employment Act (ADEA) prohibits employment discrimination against persons forty years of age or older. (www.eeoc.gov/laws/statutes/adea.cfm) The ADEA does not protect workers under the age of forty. The ADEA as stated, forbids  discrimination when it comes to any aspect of employment, including hiring, firing, pay, job assignments, promotions, layoffs, training, fringe benefits, and any other condition of employment (www.eeoc.gov/laws/types/age.cfm). Additionally, any policy implemented by an employer that is to be directed at the entire workforce, can be deemed in violation of the ADEA if the policy has a negative impact of employees over the age of forty. What is being done to address the issues you identified? The ADEA act is an important step in providing equality to the aging population in the workplace. Many older people resent the fact that they are capable of receiving senior discounts of have automatic memberships in clubs such as AARP. To combat feelings that these ideas bring about, I believe older generation are trying to stay more active in society whether it be by exercise and recreational opportunities or just being involved in non-profit organizations and active members of society. Maintaining and active lifestyle by recreational opportunities or exercise also helps to deter the effects of differing physical characteristics brought about by age. Is the number of aging population expected to rise in numbers or decrease? The older population–persons 65 years or older–numbered 39.6 million in 2009 (the latest year for which data is available). They represented 12.9% of the U.S. population, about one in every eight Americans. By 2030, there will be about 72.1 million older persons, more than twice their number in 2000. People 65+ represented 12.4% of the population in the year 2000 but are expected to grow to be 19% of the population by 2030. (http://www.aoa.gov/Aging_Statistics/) What types of legislation may or may not be affected by the aging population? There are many issues facing the elderly today any many could involve legislation affecting such things as Social Security benefits and also healthcare benefits. The development and workings of groups aimed at protecting not only the threatened benefits of Social Security and healthcare but also other aspects of the elderly lifestyle are on the rise and proving to be helpful to our aging society. How does poverty affect the aging population? Poverty among the elderly is seen as much better today than it was in the past. This can be attributed to pension plans and higher paying jobs that  what people were subject to quite some time ago. Although the rate of poverty is declining in the elderly, poverty is still an issue. One major cause is the rising cost of long term healthcare and medicines. With the increased life expectancy rates, this only compounds the problem as people are living longer. Part II Answer the following questions in 100 to 200 words each. Provide citations for all the sources you use. What does the ADA provide for people with disabilities? The Americans with Disabilities Act of 1990 prohibits private employers, state and local governments, employment agencies and labor unions from discriminating against qualified individuals with disabilities in job application procedures, hiring, firing, advancement, compensation, job training, and other terms, conditions, and privileges of employment (http://www.eeoc.gov/facts/fs-ada.html). The ADA provides for accessibility by individuals that otherwise might be limited by disabilities in an attempt to provide equality in society and the workplace. How have people with disabilities been treated in the past? Throughout history, people have been socially disadvantaged, not because of the limits of their own skills and abilities but because assumptions are made about them based on some group characteristics (Pearson, 2012). As a society we tend to fear the unexpected and naturally limit interactions due to this feeling on unknown. In doing so, we have created a sense of separation and a lot of times cause unnecessary feelings of dejection among the disabled community. How has the attitude toward people with disabilities changed over time? Over time I think as a society we have become more aware of actually how much alike people with disabilities are to us. As we move into a more adventurous society, more unfortunate accidents occur and more and more people are likely to become physically disabled. The end result of this would be a better understanding among all of society of the differences and hardships people with physical disabilities face on a  daily basis and allow us to focus on wa ys to provide equal access and quality of life. What are some unique circumstances or issues encountered by people with disabilities? People with disabilities, physical or mental, face issues and unique circumstances on a day to day basis that can make life challenging. Access to retail environments, restaurants or any public venue is often times limited by the level of accessibility provided by local businesses or governments. People with learning and/or mental disabilities could face issues of increased level of difficulties in the learning environment which in result could cause limitations in the workplace. What is being done to address those issues? The ADA Act is eventually going to force all businesses large and small to abide and provide access to disabled citizens. The U.S. Department of Education allocated more than 19 million dollars in grants to help prepare those with disabilities to receive their educations (www.whitehouse.gov/issues/disabilities). What types of legislation have been introduced to address issues faced by people with disabilities? The President of the United States signed into law the â€Å"National Alzheimer’s Project Act†, which will provide council on research, care and services of this disease. The President also reauthorized the â€Å"Early Hearing Detection and Intervention Act†, which will provide screening, intervention and research into hearing loss. The â€Å"Christopher and Dan Reeves Paralysis Act† was also signed into law, which is aimed at improved the lives of those affected with paralysis (www.whitehouse.gov/issues/disabilities). The President also signed sever al laws dealing with education and employment oppurtunities for those with disabilities as defined on the White House disability issues website.

Attitudes Towards Minorities With Mental Illness Social Work Essay

Attitudes Towards Minorities With Mental Illness Social Work Essay Members of ethnic minority groups are faced with several barriers that prevent them from adequately participating in treatment for mental illness. Mental illnesses are commonly overlooked and untreated due to the negative connotations that surround them. Minorities with lower socioeconomic status frequently have poor physical health, which creates vulnerability to mental illness pooled with a lack of affordable treatment and accessible resources. Stigma along with various beliefs and attitudes generates discrimination and social distancing behaviors towards persons with mental illness, as a result of the direct affects of ignorance, negative attitudes, and common beliefs. This often results in discrepancy and underutilization of service amongst minority populations. Mental Illness is a disorder of the brain that affects a person’s mood, thinking and behavior (Cohen 2002, NIMH). Mental disorders are all around us, however, in many cases some are overlooked. According to the Na tional Institute of Mental Health an estimated 26.2 percent of Americans, ages 18 and older, suffer from a diagnosable mental disorder each year; an estimated 45 percent of those with any diagnosable mental disorder meet criteria for 2 or more disorders (NIMH 2010). Serious mental illnesses interrupt a person’s ability to carry out essential aspects of daily life. There are several different types of mental illnesses some of which are more severe than others, however, the most common disorders are depression, anxiety disorders, panic attacks, bipolar disorders, phobias, eating disorders, substance abuse, dementia, and schizophrenia (Kobau 2008). Causes of mental illness range from inherited traits and genetics to biological, environmental and social cultural factors to life experiences, such as excessive stress. When mental illnesses are left untreated, it can cause emotional, physical and behavioral health problems (Cohen, 2002; Whitley, 2010). However, due to stigmas and va rious negative connotations surrounding mental illness people often try to reject, ignore or self medicate the illness in a state of denial (Cohen, 2002). Moreover, poverty is an important moderator of the correlation between serious mental illness and social problems (Draine, 2002). African Americans as well as minorities are more prone to suffer from significant and persistent disparities within the mental health system (Whitley, 2010). This research paper will examine racial differences of both men and women suffering from common mental illness disorders and their usage of mental health services associated with stigmas. Minorities suffering from mental illness are often less likely to access service from a mental health professional, and will more often receive poor quality care or drop out upon admittance (Whitley, 2010). Stigma and Discrimination The term stigma originally derives from the ancient Greek practice where criminals were branded, leaving them with a mark referred to as a stigma that allowed them to be easily identified (Gibson 2008). Persons with a stigma were usually rejected from society, viewed as outcast, and devalued by society similar to persons suffering from mental illness. Due to the stigma attached to persons tormented by mental illness, it forms a lack of personal contact with persons suffering from these disorders; resulting in a lack of knowledge, which in turn leads to prejudices, negative attitudes and stereotypes towards them (Alegria 2002, Guimà ³n 2010). Stigmatization of persons suffering with mental illness stems from socio-cultural, ethnic, religious, and economic factors (Guimà ³n, 2010). Stereotype-based negative attitudes and prejudices towards mental illness develop early in life, originating from cultural, historical and media depictions (Sartorius Bauman, 2007; Guimà ³n 2010).

HR professionals often do not have the accounting, economics knowledge. The same professionals are not adept at business management theories. Similarly, the HR professionals may not have the capacity to assume and manage business risks (Wallace, 1982). Implementation of policies. HR professionals can help employees implement company policy, without wasteful overstaffing. The HR professional can recommend more effective interviewing, hiring, training, promotion, and termination, matching skills to fill vacancies, retention and pay issues. The HR professional contributes to the improvement of the employees’ current job outputs and consistency with internal environment factors. For example, the office clerk who is slow typist can improve work output with the HR professional’s help. The HR professional will engage the employee in timing speed seminars and other trainings. The employees will enthusiastically enroll in the HR professionals’ program to increase their data encoding or typing speed (French, 1982). Change leaders. The HR professionals help employees embrace company changes. It is normal for company to institute changes in company policies and procedures. Changes include product and services changes. Customers often change product and service choices. The company must supply the new products and services. For example, the demand for the old fashioned typewriter was replaced with the later demand for computers (French, 1982). The HR professionals will contribute to reduce resistance to change. The HR professionals will use seminars to equip the employees with the necessary capabilities for successful change. HR professionals will

The Unorthodox Owner Case Study Example | Topics and Well Written Essays - 1000 words

The Unorthodox Owner - Case Study Example The structure is completely wrong. It defies normal marketing standards. The prior standard indicates the employees with higher revenues will get higher commissions than employees with lower revenues. The new commission pool pays people who do not actually sell or complete Second, the confused employees did not know how to correctly respond to the new unorthodox marketing strategy. It is wrong to confuse the employees. The confused employees do not know the intricacies of the equality distributed commission pool. Third, Wilkinson did not indicate the responsibilities of the new chief operating officer. Consequently, the new COO does not know what he should do in the new job. Consequently, the COO may not be implementing what the owner, Wilkinson intents because of the miscommunication. Finally, Wilkinson wanted the commission pool to be evenly divided among the sales people, both top sellers and lackluster performing sales persons (Zoratti 19). It is wrong to distribute the commission equally among all the sales persons. The implementation will indicate that employees with low revenues will receive the same amount of commission as the sales persons generating ten times the amount generated by the low revenue-generating (Burton 26). For example, the sales person generating the $ 1,000,000 top selling sales persons will receive the same $ 10,000 commission as the sales person generating $ 1,000 sales for the same month (Ross & Lemkin 4). To generate the required net profits, the company must produce the profit-generating responsive revenues (Boone 14). In addition to the bonuses, Wilkinson increased the commission from 5 percent to 7.5 percent (Hartline 270). The compensation plan influences sales performance (Dougherty 1). Mr. Wilkinson should not implement the unorthodox commission and bonus scheme without fully explaining the details of the new scheme. Mr. Wilkinson’s spending more time giving a

Reflective commentary Assignment Example | Topics and Well Written Essays - 1000 words

Reflective commentary - Assignment Example Defining the substance of the study made it possible to undertake a focused study without going off-topic ‘(Hartley, 2010)’. The definition was followed by a further inquiry into the components of the council, with a focus on the parties that make up the council, how they are selected and the powers they wield. These components were better explained by the book titled The Foundations of EU Law by T. Hartley. This was an important step, since it broadens the study in a systematic manner. This is because, the study advances from the mere definition to understanding the components of the body and the powers held by the parties. Having understood the components of the EU council as a decision making body of the EU, it was relevant to understand how the decision making process is undertaken. This required some inquiry into the procedures of undertaking meetings, their venues and what the meetings entail. At this stage, the broad topic was narrowed down to engage in understand ing the specific details of the EU council meetings, who arranges them and how the agendas are raised ‘(Hartley, 2010)’. This is when the book titled Unlocking EU Law by T. Storey and C. Turner, became relevant, since it explained all the procedures of the meetings and the changes in venues at different times ‘(Storey & Turner, 2011)’. ... In studying the role of the EU council as a decision making body of the EU, I visited the Law Teacher website to obtain credible information. Additionally, reliable and relevant sources, which particularly address the EU council and its roles were consulted. Here, the second edition of the book by A. Kaczorowska, titled European Union Law proved worth, since it comprehensively addressed the EU council and its functions ‘(Kaczorowska, 2011)’. Therefore, the resources used were the ones directly addressing the decision making process of the EU, since they would discuss this topic widely and venture into finer details, compared to other sources which generally address the EU holistically. I used The Foundations of EU Law by T. Hartley, to gain the basis the EU council decision-making mandate ‘(Hartley, 2010)’. The process of selecting the resources for use entailed consulting both the old and the new version of such resources, since a combination of the old and the new resources could be more informing than dwelling on either version. I used the third edition of Unlocking EU Law by T. Storey and C. Turner to gain an insight on how the decision making mandate of the EU council has changed over time ‘(Storey & Turner, 2011)’. Additionally, sources of information that addressed the decision making role of the council both before and after the EU enlargement were consulted, since they could give systematic information regarding the changes in the roles of the council. Here, the book, EU Law by J. Steiner, became relevant for this purpose ‘(Steiner, 2012)’. Therefore, a range of resources were consulted, to compare and contrast the information obtained, and settle on the most promising details. The

Contemporary Issues in Information Systems Research Paper

Contemporary Issues in Information Systems - Research Paper Example Additionally, at the present there are numerous CASE tools which can be used by software development teams. These tools offer rigid policy and standards about implementation and design of the systems (Lamb, 2012; VisualCase, 2012). In addition, a number of the advantages offered by CASE and other similar techniques are that, by making the client element of the software development process (for instance by analyzing the marketplace and focus groups); a product is further possible to convene real-world requirements and features. In view of the fact that software development process heavily relies on redesign and testing, hence the price of servicing an application over its lifetime can be reduced considerably. In this scenario, a carefully established technique to development offers assurance for the code and design reuse, minimizing expenditures and improving value. Ultimately, quality software products are likely to develop a company’s image, offering a competitive edge in the market (Rouse, 2005). This report presents a detailed analysis of two major market leaders of CASE tools. Basically, this report presents an analysis of two major applications IBM Rational Software and Oracle Designer. These tools contain wonderful features and provide an excellent support throughout the software development process. This report will present the comparison of these two applications and specification of major features for more enhanced performance management of the application development. In this scenario, this research will assess these two products on the basis of different features and quality parameters. Analysis This report presents a detailed analysis of two leading CASE tool applications by comparing their features and attributes. In this scenario, I will compare and contrast IBM Rational Software and Oracle Designer on the basis of Repository (it demonstrates how the selected tools is using repository), Forward engineering features, Reverse Engineering feat ures and Modeling tool features. I will assess both applications of above stated characteristics to suggest a most excellent application. Repository IBM Rational The IBM Rational Case tools offer information that is able to improve quality of software development groups to function more efficiently and productively. Additionally, IBM Rational Rose permits development teams to uphold, capture and take benefit of software knowledge by means of a repository available to people through a web and Eclipse interfaces as well as to programming through a RESTful web based interface (IBM, 2012). In this scenario, Eclipse plug-in integrated in Rational Developer for System development connects the software developer to local as well as remote RAA repositories. In fact, it as well scans software application source files from local and remote workplace IDE software development projects into a local RAA system repository (IBM, 2012). In addition, the capability to scan symbols in some kind of fil e scanned by the Rational Asset Analyzer representation scanner, including the results into the Rational Asset Analyzer repository and comprising the data and information in the inquiry and analysis services. Moreover, it integrates information from a wide

Discuss Soil Exhaustion as a major contributing factor leading to the Essay

Discuss Soil Exhaustion as a major contributing factor leading to the American Civil War by addressing the significant events from 1798 to 1861 - Essay Example From 1800 to 1861, there were high percentages of slaves in the South than in the North. During this period, there were slave rebellions; most of the slaves were captured and executed (McNeese 7). Southern states kept government spending and taxation at low levels due to high debts as compared to the North. Southerners were incapable of supporting education as compared to the Northerners. Illiteracy was widespread in the South; in 1850, 20 percent of all white adults in the Southern states were illiterate. In the North, illiteracy was less than one percent. Though slavery was profitable, it contributed to soil exhaustion, lack of technological innovation and high debts. Soil exhaustion and erosion diminished cotton land availability. High demand and scarcity resulted to increase in price of land and slavery. Planters enlarged their holdings, and as a result, they pushed off yeomen farmers from the land. As slaves and land possession became more concentrated, harsh economic conditions led to migration to urban areas. Urban population increased in the North leading to urban poverty and low industrial wages. This migration caused fierce differences between the South and the North (McNeese 8). On March 1807, Congress passed legislation, which banned the importation of new slaves into U.S. From 1803 to 1861, various countries joined unions of either demarcated Slave states or Free states. The Congress increased tariffs in 1828 with the Tariff of Abominations. The tariffs aimed at supporting the U.S. industry; these tariffs benefited the Northern industrial economy while damaging the Southern agricultural economy. From 1827 to 1861, slavery was abolished in New York, District of Columbia, and British Empire. In 1833, the Compromise Tariff Act was passed to reduce tariffs of concern in the Southern states; it averted the confrontation. In 1851, the

Assigment 2 Essay Example | Topics and Well Written Essays - 1000 words

Assigment 2 - Essay Example The Texas State Senate and United States Senate allow their members to filibuster bills. This paper analyzes the similarities and differences between Texas state senate and United States senate filibustering. Similarities In the US, filibustering is a powerful legislative tool and it has been used to influence many senate proceedings and outcomes. For instance in the united states senate, most major legislations require over 60% votes before being nominated for a house debate. While filibustering may be viewed as a democratic move in most senates, most people believe that filibustering is negative and uncalled for in any proceeding. This is evident in both the US and Texas state senate’s, where parliamentarians have created bills to stop filibustering. Filibustering has also attracted positive criticism in both the US and Texas state senate. For instance filibustering has been used to shun contentious bills from being passed without prior participation of all senate members. F or instance, the abortion bill that threatened to criminalize abortion and instruct the closure of all abortion clinics has been delayed due to the existence of filibustering in the Texas. Thus, in both the US ant Texas state senate, filibustering has positive and negative criticism. Senate Rule XXII, the US state senate allows certain senators to prolong a bill or a speech for as long as they can. The law recognizes the necessity to prolong certain bills. This is usually true in both the US and Texas senate. In the US senate, prolong a house debate was an open practice until the house of representative passed a permanent rule in 1842 to limit the length of debates. Similar measures have been taken in the Texas state senate to regulate house debates. There are many uncertainties in filibustering bills as administered in both senates. The main issue attached to filibustering, is the determination of the length of a debate. According to critics, it is impossible to determine or out ru le, the length of a bill based on the filibustering policy. For instance, it is impossible to define how long a long speech is. Lack of a clear-cut definition on the length of a debate has been applied by critics to shoot down filibustering bills. Lack of clear-cut policies on filibustering is evident in both the US and Texas state senate. The passage of filibustering legislations has not been welcomed by most senators who use lengthy discussions or debates to prevent or influence the passage of bills. The issue of filibustering is commonly associated with US politics. In both the Texas and US senates, republicans are believed to be the main filibusters. The political association is historic and it has minimal implication on bill passage. However, senate proceedings are influenced by the US senate. More so, the bill of rights and other contentious issues are often ruled out depending on political affiliations. The rules of both houses are clear on the issue of filibustering and neit her of the houses identifies filibustering as a political issue. Indeed, both senates recognize filibustering as important in any proceedings. The cause of filibustering in both the US and Texas senate are similar and they are protected by the law. For instance the in the US senate, most common filibustering occur when a senator attempts to delay or obstruct a vote or a bill. On such

The Timucua Indians of Northern Florida Essay Example for Free

The Timucua Indians of Northern Florida Essay The Timucua Indians: All were settled agricultural peoples, as skilled with their hoe as they were with canoes or with bows and arrows. They lived in villages, where they cultivated corn, beans, and other crops. Noted warriors, they fiercely resisted early attempts to bring them under submission, but co existed peacefully with the Spaniards for most of the first 198 years of Spanish occupation. Source: Muller, Peter O., Gannon and Fernald, Edward, A. â€Å"Florida† Microsoft Encarta 2006 (DVD), Redmond, WA: Microsoft Corporation 2005 The Cherokee- were divided into seven matri lineal clans that were dispersed in war and peace moieties (half-tribes) The people lived in numerous permanent villages, typically placed along rivers and streams. Some villages belonged to the war moiety, the rest to the peace moiety. Cherokee families typically had two dwellings: rectangular summer houses with cane and walls and bark or thatch roofs, and cone shaped winter houses with role frames and brushwork covered by mud or clay. The Cherokee crafted pottery as well as baskets. The bask, or Green Corn Ceremony, was a time of Thanksgiving, Forgiveness, Rekendling of Sacred Fires and Spiritual Renewal. It was held in Mid-to late summer, when the corn was ready for roasting. Source: Waldman, Carl â€Å"Cherokee† Microsoft Encarta 2006 (DVD). Redmond, WA: Microsoft Corporation 2005 (Writer’s notes: These are the only pictures I got) Source: University of Washington Libraries, Digital Collections. Comparing the Timucua and Cherokee Indian tribes. Both of them are engaged in Agriculture. I think, the Timucua are the warrior type. Mentioning their skills with canoes and bow and arrow. The attitude of resisting early attempts to bring them under submission. For me, it is a rigid culture and thinking. While the Cherokee, who were subdivided Into seven matri lineal clans or half tribes, were the flexible type of people. Since being a warrior means to kill people, who are supposedly the enemy. The Cherokee, though, they also have their warrior clans. But the practice of Green Corn Ceremony made them the exact opposite of the Timucua Indians, who are more on skills, this is about physical attributes. While the Cherokee is on non-physical attributes. To be a warrior, means being engaged in wars or warfare, which means about being fierce and destructive. But on the other hand, for the Cherokee,I consider them to be the constructive, and productive type of people. Though, the Timucua, for being resistive against their enemies must have spent a lot of time developing and training for the skills in war. It is like choosing two things. You resist, but you will become less productive, yet if you submit, then you will learn something new and perhaps will have a much better life. Now, what it means to submit to a superior force, who were their enemies at that time, is it becoming a slave and their self-respect gone. Perhaps, for the Timucua, it is better to fight and die. At this moment, presently we have the advantages in terms of education. The Indian tribes, are then considered as ignorant, but history is actually the judge of which each of us shall learn something. For me, a warrior thinks differently. And it is something which is unique for a tribe, or a culture, something inherent, of which one cannot take away or get rid of it. The only way perhaps, is to find a way to help him change his mind.

American National Identity And National Parks History Essay

American National Identity And National Parks History Essay Natural identity can be simply defined as the individuals sense of belonging to a nation. It is the thread that binds the citizens of a particular nation together and gives them the pride of belonging to the country. According to Smith national identity serves three important functions; it provides an answer to the fear of personal oblivion through identification with a nation since the nation is far greater and stronger than the individual; is this your language? national identity offers the individual personal renewal and self-worth by being a member of a super family politically and thirdly it promotes the realization of fraternity feelings more so through the use of symbols and ceremony  [1]  . Remember: punctuation inside of note numbers! Make sure you really paraphrase or quote directly. This seems not like your language. Every nation around the world has its main national identity. For some, it could be talking the same language as it happens in most European countries where nations are defined by their language such as France for the French speakers, Spain for the Spanish speakers, Portugal for the Portuguese speakers among others. [awk and unclear] In other countries national identity is defined by ethnic composition for example Slovakia for the Slovaks, Albania for the Albanians and Armenia for the Armenians. In other countries national identity is defined by religion such as in the Muslim countries and in Israel. [I think this is pretty simplistic national identity is much more complicated than this] America however is unique because it is a mixture of all. The Americans cannot be judged by race because all races are represented, neither by language because virtually all major languages are represented, neither by culture because America is a boiling [melting?] pot of all major cultures nor by r eligion because all major world religions are represented in America by a substantial number  [2]  . [awk] is this a point you are making or one that someone else has made that you are using. Make that clear. Americans often face the great task of establishing national identity for themselves. [think about that different types of national identity coexist there are battles in all countries about what constitutes Britishness or Americanness or Frenchness. Maybe its more complicated in the US, but Im not sure, but I dont think American are unique in having to choose among different ideas of the nation which are presented in a variety of ways] Because of the importance of nature to American self-identity, [you need to show this, not assert it] environmentalism questions have always tended to take on ideological and national significance. Preservation of natural spaces in America has involved both the creation of an alternative cultural space for the nation and creation of America as a nation  [3]  . [unclear] Americans found in national parks a unifying factor; a national identity that is to America what culture [culture is a vague term here] is to Europe. Therefore national parks are c entral to Americas national identity. This paper is going to evaluate the relationship that exists between Americas national identity and national parks. The paper concludes that national parks are the national identity of the United States of America. National parks express a certain aspect of the national identity of the US? To say they are equivalent may be stretching it . . . The first national park in the world was established in 1872  [4]  . This is Yellowstone National Park. Yellowstone National Park became the first large scale wilderness conservation in the interest of the public and more so the generations to come. The rest of the world learnt the idea of national parks from America. Each country launched its own version of parks but the American model was the one that was largely used. To Americans, wilderness is not only idea but rather it is the objective of many who are seeking outdoor recreational activities. [clarify] According to Roderick Nashi, wilderness is a state of mind; the feeling of being far from civilization, from the environment that humans have polluted.  [5]   Natural landscapes which form the national parks are fundamental subjects in the understanding of national identity. This is so because nature as opposed to culture has increasingly become a source of national identity. National identity therefore can be seen as a heritage of nature. You need to make these connections clearer maybe talk about the issue of the frontier thesis? According to Howard and Graham  [6]  , the role of the natural landscapes in shaping national identity is increased by the fundamental link between ideas of the national, the native and the natural in which the prefix nat refers to a notion of birthing. Howard and Graham argue that the nation is therefore logically made up of the natives who have been born as a community of nature that gives the nation its common identity. Cite and make sure this is your language. A large number of national songs sing in praise of the nations natural landscape, for example America the Beautiful which celebrates Americas purple mountain which stands majestically above the plains and stretching from sea to sea  [7]  . There are also a great number of museums and theatres that are decorated using landscape images of natural scenes. Such as? You need to set up a more systematic organization at the outset here : introduction with your thesis; historiography how have historians written about national parks; and then perhaps background. Right now I feel like you are jumping around a bit too much. When the European settlers arrived from Europe they settled in the eastern shores of what would become the United States. However with time the population grew rapidly and with it came the need to push further west. This led the settlers into what was referred to as the Wild West. The settlers portray the Wild West as an area that had not been occupied, though we know that the Native Indians occupied the area. By so doing the settlers saw themselves as a new nation in which different people from diverse nationalities were reborn as one nation in the wild nature of the new continent. Citations! The importance of the Wild West in the history of the U.S cannot be overemphasized. Many Americans identified themselves as Americans from having been born in the continents Wild nature. Can you show this with primary sources? Due to the importance of the wild nature in rebirth of the U.S [?] it became essential to conserve part of the wilderness undisturbed in order to act like a reminder of the countrys rebirth. [could be clearer] This need acted as the ideological basis for forming national parks in the 1880s. The national parks were started in large areas with wild nature. The aim was to preserve these areas for future generations. Citations! The national parks exist to protect salient natural areas from threat of human destruction through political social and economic development. This preserves the wilderness as it was when the European settlers took possession of the land. Indeed it is this wilderness that defined Americas national identity from the time the nation was established  [8]  . [you need to SHOW this through analysis -not assert it] Construction of the American national identity is rooted deeply in nature that the two are inseparable. Awk This is in contrast to European nations, whose national identity is derived from sharing a common language, ethnic or racial heritage, religion or cultural history. America is a nation of diverse languages, diverse ethnic groups, of all races race, with virtually every religion represented and of a people with diverse cultural background  [9]  . Repetitive Race, language, ethnic group, religion and culture could not therefore be the American national identity. Amer icans found a rallying call in nature, in exploring the wilderness in the west and when much of it was getting depleted, the government started the idea of national parks aimed at protecting large swathes of the untamed wilderness for future generations. This gets repetitive youve made all these points in different places already. The national park concept has been said to be the most successful idea yet conceived in the protection of the environment.who said this? It is an American idea that spread around the globe  [10]  . The national parks were started to preserve natural and cultural heritage. Americans were particularly concerned about preservation of the natural environment for the sake of those who would want to vacation outdoors. Nature and sceneries were to be protected for the enjoyment of all human beings. In these wildernesses, people would find a serene atmosphere to relax away from the pollution that civilization engineered. Connect these themes to national identity a way for Americans to experience their land? Seeing the true America rather than the cities? The Wild West had been largely cleared by settlers and conservationists realized that unless action was taken, the whole land would be taken over by civilization denying future generations a chance of learning the history of their founding further or the culture. [unclear] Therefore preservationist and conservationist started creating awareness of the need to set aside large portions of the remaining wilderness. This process did not gain momentum until the latter half of the 19th century. From thence the first national park was established in 1872 with others following albeit at a slow pace  [11]  . [repetitive] Not all the areas that were designated as national parks were without human habitation; some areas were already inhabited by either the Native Indians or by white settlers also called frontier farmers. When the boundaries of the national parks were drawn, some of these groups met themselves [?] inside the area that had been demarcated as a national park. The federal government had then to move them out. With some resisting to be taken out of what was their rightful possession, the Federal government was forced to apply force in removing them. [awk] This resulted in long standing grudges between the communities that were forcibly removed from the designated parks and the government  [12]  . In Yellowstone national park, for example, the Indians were forcibly relocated. This caused long standing grudge between the federal government and the Indians and between the Indians and the white population whom they viewed as the government. The Indians responded by firing at tourists who visited the park. Tourists visiting the park had to do so under protection from security agencies  [13]  . The sheepherders and lumbermen had to look for new ways to feed their families. The activities that were legal, the source of livelihood that they had lived on and not only them but the generations of descendants back there was declared illegal and refused. This was of course. Youve got good secondary sources Im waiting to see what you do with the primary sources. To these Indians and frontier whites whose farms were taken away as part of parks, they would not understand how the same thing that they were living on in the days gone by could now be declared illegal. Awk The lives of the Indians were shattered. This is because their way of life had been interrupted and declared illegal henceforth. Hunting and fishing, that had always been part of their lives was termed as poaching while foraging would now be termed as trespass both of them now acts punishable by law. Cite. Examples? The deep-seated anger this action brought to the Indians is manifest today. Some Native Indians that like the Blackfeet, representing about on, have running cases against Glacier national park. They are demanding recognition according to 1895 legislation  [14]  . Awk; and you cite a source from 1901, so Im not sure how this reflects feelings of today. Obsession with pristine and uninhabited wilderness provided many misconstrued ideas and facts that led to brutal confrontations between those for conservation and preservation and those trying to provide a decent meal for them and their children. unclearThe National Park Service Act of 1916 established the dogma for park management, the chief policy for philosophy, policies and decision-making  [15]  . And? What do you want to say in this paragraph? The use of national parks as a symbol of national identity is based on two-fold role in reinforcing national identity: the national park system helps to passively express that national identity and to passively transmit it. Im not sure what this means. The national parks are an integral part of American life. Their use is extensive; they are used in post cards, in picture movies, depict and symbolize what America is  [16]  . Yes The initial impetus for starting the national parks system was the desire to have a unique national identity. Was that stated explicity? Sources? Preservation of the best scenic sites in the U.S was seen as what would create a differentiation between the United States and the European Countries. Parks would be a way for the young United States to compete with European countries which already had established national identities based of their cultures that they had build over thousands of years. The adventurers nature of the American people and their love for the wild would also blend well with national parks as a national symbol. Parks express the American identity. In addition to expressing the goals shared by society, parks play a major role in transmitting those values to the society at large and members of the national community  [17]  . I think all these points are interesting but you are essentially repeating the same things, and you havent illustrated your points with supporting evidence from primary sources. National parks are created through a political process and may even reflect the political thought of the day. Having realized the political dimension involved the establishment of national parks; conservationists have devised ways of engaging politicians in nature conservation. When? The relationship between politics and national parks is further demonstrated in the construction of nation-states, more so the evolution of national identity. Totally unclear Identity development involves the mobilization of images, myths and so on  [18]  . [is this your language?] The concept of wilderness was central in the evolution of American identity, with Yellowstone National Park representing American cultural iconography while at the same time creating confidence among the members of the public in the industrializing nation  [19]  .[watch language] A common political concept of national parks has developed in the area of national identity. Unclear This is not a surprise because earlier c oncepts of national parks have been permeated with nationalist aspirations. The American landscape, in fact, emerged as a strong source of national identity construction  [20]  . This paragraph is unclear to me, and it also repeats points youve made earlier. The appropriation of national parks as an American national symbol, like all other nationalism, was exclusionary. Native Americans were not included in a nationalism that had been established on the very land they occupied. In that sense, Yellowstone National Park was symbolic of a nation that was divided between the settlers and the natives. Interesting point Beinart and Coates argue that Americans attempted to create national identity out of natural grandeur because the United States found it difficult to compete with Europe in high cultural stakes. Youve said this. Citation? To get a deeper insight into the relationship between America national identity and national parks, it is important to pay closer attention to a number of parks. This is not a paragraph. Yellowstone national park is the first national park in the world. By next year, the park will be celebrating its 140 years. The park measures 2.2million acres  [21]  . The area was sparsely populated at the time of starting the park but the government had an oversight that of how things will be in future. unclear Inside the designated area there was human settlings mostly made up of Native Indians and a few Frontier farmers. Youve said this already The government acquired all private land within the demarcated area and evacuated the people. The Native Indians having lived in this area did not welcome the relocation. However the government ensured they do. [?] This left the Indians bitter. To revenge the Indians continued hunting in the protected area as if unaware the new change of status. They also attacked the tourist who came to visit. This prompted the government to send the Calvary troops there in 1886 to stop poaching and to protect the tourist  [22]  . The Calvary sol diers went to Yellowstone and built Fort Yellowstone where they stayed until 1916 when the National Park Service (NPS) was established through the Organic Act of 1916. Youve said much of this already. Please combine the same points in one area of the paper. Yellowstone was used by the 19th century American Indian belonging to the Crow, Blackfoot, Shoshone and Bannock tribes  [23]  . unclear Some continued to live in the park even after it was designated. However in 1877 there were troubles which occasioned three hundred deaths. The Indians were forcibly removed to the Wind River Reservation. The Calvary soldiers were brought in and they protected the park between 1886 and 1918. Basically repetitive The removal of Indians follows a pattern of their removal from their farmlands to give way for settler farmers only that this time they were removed to provide vacation sites for tourists majority of them who were whites. Were the parks explicitly established for tourism? You need to bring in primary sources to discuss this. The African Americans and the Latinos did not go to the national parks often because they did not find them welcoming  [24]  . When? sources? Yellowstone is home to over 1100 structures associated with Euro-American occupation and management of the park. The legacy of early civilian and army administration and the history of concessions in national parks are preserved. ? Some of the historic landmarks are; Fishing Bridge Trailside Museum, Madison Junction Trailside Museum, Obsidian Cliff, Northeast Entrance Station, Norris Geyser Basin Trailside Museum and Old Faithful Inn. Why do you need to list these? The park has four National Historic Districts: Lake Fish Hatchery, Mammoth Hot Springs, Old Faithful and Roosevelt Lodge. The park is also home to five National Historic Sites: Lake Hotel, Lamar Buffalo Ranch, Obsidian Cliff Kiosk, Queens Laundry Bath House and the U.S Post Office at Mammoth Hot Springs. The park is also home to 200,000 natural and cultural objects including artwork, ethnographic and archeological artifacts  [25]  . Im not sure why you need this paragraph. A substantial history of the United States is kept in the national parks. These are central to the national identity of the nation. How? What is the history that is preserved there? As seen above the history of Yellowstone national park is closely intertwined with the history of the United States to the extent that the nation can be seen through the park. But you havent illustrated this with primary sources. Its a good point, but you need to demonstrate it, not assert it. Glacier National Park with its many peaks, clear waters, and glacial curved mountains reflects Americas identity. As previously mentioned, Americas national identity is defined by her landscape the most spectacular being protected in national parks. Awk Throughout history, people visited Glacier National Park for the adventure it provides. Evidence of human habitation in this area goes back to 10,000 years ago. By the time of Europeans arrival, the area was inhabited by Native Indians of the Blackfeet, Salish and Kootenai tribes. They travelled to the mountains to hunt various kinds of game that were available in this place. Citations? Significance? The Europeans were attracted to the area primarily for economic gain. Some came as explorers, others as miners and eventually the settlers arrived. The Great Northern Railway reached Montana in 1891 and from thence great number of people flocked to the area attracted by prospects of mining and other economic activities  [26]  . Around the turn of the century, people began to look at Montana region as an area that was suitable for something more than farming or mining. They recognized that the area was exceptionally beautiful in reference to the landscape. Towards the end of the nineteenth century, influential leader led by George Grill began pushing for the establishment of a national park. Their desire was granted in 1910 when President Taft signed into law the bill establishing Glacier as the 10th national park  [27]  . But why is this significant in terms of your argument? The park has many historic buildings that are listed by the National Register of Historic Places. The park is home to 375 historic properties including six that are designated as National Historic Landmarks. The parks museum houses around 6,000 items related to its natural and cultural history  [28]  . These historic properties tell the history of the United States. What history do they communicate? Glacier as a national park is therefore related to the national identity of the United States because it is home to some of the most iconic landscape in North America. You cant just state this. . . . Yosemite is one of the United States most well-known National Parks. It largely covers the eastern parts of Tuolumne, Madera and Mariposa counties of California and covers an area of 761,268 acres  [29]  . The national park is governed by National Park Service and is recognized worldwide for its clear streams, groves, granite cliffs, waterfalls and its biological diversity. The park has a range of 648 to 3,997 meters above sea level and is divided into five major vegetation zones: chaparral/oak woodland, lower montane, upper montane, subalpine and alpine. There are more than 160 rare plants in the park. Most of the landforms in Yosemite are cut from the granitic rock of the Sierra Nevada Batholiths. About 5% of the parks landforms are metamorphosed volcanic and sedimentary rock. The valleys, canyons, domes and other features seen in the park were formed as a result of erosion acting upon different types of uplift-created joints. Citations? Significance? Yosemites most outstanding features include the tunnel view, which is the most visited area and also the most photographed; a prominent granite cliff that looms over the valley, the El Captain, which is has diverse range of climbing routes and full-yearly accessibility thus making it the most popular rock climbing destination in the world. The high parts of Yosemite contain spectacular areas such as: Dana meadows, Tuolumne meadows, the Clark range, the Cathedral Range and the Kuna crest. In addition, the park has three groves of ancient Giant Sequoia trees, the Mariposa Grove, the Tuolumne Grove and the Merced Grove. These tree species grow larger in volume than any other and is one of the tallest and longest lived. Citations? I just found some of this information on a website, and you are not citing . . . Yosemite falls under a Mediterranean climate with mean daily temperatures ranging from 25 to 53 degrees Fahrenheit. Most precipitation occurs during the mild winter, and the remaining seasons stay almost dry. Snow accumulates all winter and into March and April. It however does not persist on the ground until November in the high country. At areas above 8,000 feet, the hot and dry temperatures are moderated by frequent thunderstorms, during summer, along with snow in July. This combination of low relative humidity, dry vegetation and thunderstorms results in frequent lightning-caused fires  [30]  . The park contains about 3200 lakes, two reservoirs and 1,700 miles of streams. Landforms in the park have been created as a result of hydrologic processes, including glaciations, flooding and fluvial geomorphic response. Yosemite is popular for its high concentration of waterfalls in a small area. These include: Yosemite falls and Ribbon falls both found in the Yosemite Valley, Bridal veil fall that is seen from the Tunnel View viewpoint and Wapama Falls in Hetch Hetchy Valley  [31]  . Paiute and Sierra Miwok are the people who lived in Yosemite area long before the whites explored into the region. The Ahwahneechee, who were Native Americans, lived in Yosemite Valley when the first foreign people entered .White travel increased in the area in the mid-19th century due to the California Gold Rush  [32]  . Jim Savage of the States Army led the Mariposa Battalion in 1851 to the west end of Yosemite Valley in while pursuing around 200 Ahwahneechees led by Chief Tenaya as part of Mariposa wars. Chief Tenaya founded the Pai-Ute colony of Ah-wa-nee. The Miwoks, most white settlers, saw the Ahwahneechee as violent owing to frequent territorial disputes. Tenaya and all the Ahwahneechee were later captured and their village burned; they were moved to a reservation in California near Fresno  [33]  . When some were later allowed to return to Yosemite Valley, they attacked a group of gold miners, which got them into trouble. They flew to the east and sought refuge with the Mono tribe at Mono Lake but were tracked down and most killed by Mono Paiutes after they stole some of their hosts horses in 1853.Chief Tenaya was killed in the attack and survivors were taken back to Mono Lake and they were absorbed into Mono Lake Paiute tribe. An Indian Village of Ahwanhee was reconstructed and is located behind the Yosemite Museum next to Yosemite Valley  [34]  . In 1855, James Masons Hutchings, an entrepreneur and artist Thomas Ayers toured the Yosemite Valley area. They created articles and magazine issues about Yosemite Valley thus responsible for most of the earliest publicity about Yosemite  [35]  . Wawona was an Indian encampment, now in the southwestern part of the park. Mariposa Grove of Giant Sequoia was discovered Galen Clark, a settler. Simple lodgings and roads were built in the area. The number of trails and hotels increased as tourism increased. Prominent citizens including Galen Clark and Senator John Conness, concerned by the effects of commercial interests, advocated for protection of the area. A park bill was passed by both houses of the U.S congress and was signed by President Abraham Lincoln on June 30, 1864, creating the Yosemite Grant. The park was to be set aside specifically for public use and thereby creating the first national park. It is believed that man lived in the Rocky Mountains about 10,000 years ago. The Utes lived in the mountains of West Colorado. As the Arapaho, who were plains Indians who came to the Estes Park frequently in summer to hunt, migrated westwards the Americans moved out from Appalachian  [36]  . With the arrival of Americans, Indians avoided Estes Park and Grand Lake area. Rufus Sage is the first American to have visited the region. He spent three years exploring the Rockies. Joel Estes, a Kentuckian, was the first settler. He brought his family in 1859 and eventually settled as a farmer near Fort Lupton. A few homes were set up in the upper Colorado Valley in 1879 and by 1880 people moved in to Lulu city where some gold discoveries had been made. A few homes were set up in the upper Colorado Valley in 1879 and by 1880 people moved in to Lulu city where some gold discoveries had been made  [37]  . In 1883 the town was deserted. As a result of publicity and political pressure, a b ill was passed in 1915 and signed by President Wilson to establish the Rocky Mountains National Park the Parks dedication was conducted in September 4, 19

Causes of Cardiovascular Disease | Literature Review

Causes of Cardiovascular Disease | Literature Review 2 Abstract 3 Introduction 3.1 Cardiovascular Disease Cardiovascular disease (CVD) is the broad class of diseases that involves the heart or/and blood vessels. CVD includes atherosclerosis, heart valve disease, arrhythmia, heart failure, hypertension, endocarditis, diseases of the aorta, disorders of the peripheral vascular system, and congenital heart disease [1]. However, atherosclerosis accounts for the major part of CVD (up to xx%), and sometimes CVD is misleading used as a synonym for atherosclerosis [REF]. Because atherosclerosis is the underlying disease of several CVD, part of patients, where one diagnosis of CVD became manifest, may present with further co-morbidities, especially other diagnosis of CVD are common. However, the portion of patients with co-morbidities is depending on the baseline disease [2-4]. For example 40-60% of patients with Peripheral Arterial Disease (PAD) also have coronary artery disease (CAD) and cerebral artery disease, but only 10-30% of patients with CAD have also PAD (Figure 1) [2, 4]. Further, the severity of cardiovascular co-morbidities correlates well with each other[5-7]. CVD is today responsible for ca. 30% of all deaths worldwide [8], while heart disease and stroke are the leading causes of mortality and disability in developed countries [9]. Although the mortality rates of CVD has a considerable variation across countries (xx% in xx to xx% in xx) [10], a common trend of increasing rates has been observed worldwide. Before 1900, infectious diseases and malnutrition were the most common causes of death throughout the world, and CVD was responsible for The economic burden and the public health costs are mainly driven by CVD. In terms of combined morbidity and mortality, 148 million Disability-Adjusted Life-Years (DALYs) were lost worldwide (2002), which represents about 10% of all lost DALYs [REF]. In 2008, CVD costs about 192 billion Euros a year alone in the European Union, which results in a per capita cost of 391 Euros [13]. 3.1.1 Atherosclerosis Atherosclerosis is the most frequent and important pattern of Arteriosclerosis, other forms of Arteriosclerosis are Mà ¶nckeberg medial calcific sclerosis and Arteriolosclerosis, which vary in pathophysiological and clinical presentation [14]. As described above (3.1), atherosclerosis is the leading cause of death (up to 30%) in developed countries and represents the major portion of CVD. Atherosclerosis (literal origin from Greek: athero = â€Å"gruel or paste†; sclerosis = â€Å"hardness†) is defined as â€Å"thickening and loss of elasticity of arterial walls† and describes a process, where fatty substances, cholesterol, cellular waste products, calcium and fibrin building up in the inner lining of arteries [14]. These intimal lesions are called â€Å"atheromas†, â€Å"atheromatous† or â€Å"fibrofatty plaques†, which lead into an obstruction of vascular lumens and weakness the underlying media. Even within a given arterial bed, lesions or stenoses due to atherosclerosis tend to occur focally, typically in certain predisposed regions. 3.1.1.1 Pathogenesis of Atherosclerosis Due to overwhelming importance of atherosclerosis, enormous efforts have been spent to discover its cause over the last few decades. Today, the currently accepted concept, so called â€Å"the response to injury hypothesis†, considers atherosclerosis to be a chronic inflammatory response of the arterial wall initiated by injury to the endothelium [15]. Furthermore, lesion initiation and progression are sustained by interaction between lipoproteins, macrophages, T-lymphocytes, and the normal cellular constituents of the arterial wall. This process of developing atherosclerosis, which typically lasts over a period of many years usually many decades, can be divided into several consecutive steps, as illustrated in Figure 2 [REF]. Parallel, a morphological change is observed within the artery wall, where fatty streak represents the initial morphological lesion, even so the pathogenesis has started quite earlier with a chronic endothelial injury [REF]. Figure 2: Illustration of the Pathogenesis and Morphological Development of Atherosclerosis. SMC: Smooth muscle Cell; 6 ÃŽ ¼m thick histology slices of coronary arteries stained with Movats pentachrome. A: pathological intimal thickening with a â€Å"fatty streak†; B: pathological intimal thickening with a macrophage infiltration; C: early fibroatheroma with neoangiogenesis; D: fibroatheroma with thin fibrous cap and a healed rupture; E; late fibroatheroma with a sheet calcification. * demarks necrotic scores. Histology performed by CVPath Laboratory, Maryland, MD. The below described steps of the pathogenesis of atherosclerosis shouldnt been seen as a separated processes. They are interconnected and occur parallel. Further, several mechanism of vicious circles are described [REF]. However, the stratification into the flowing six steps helps to understand the complex pathogenesis and represents the current understanding: (1) Chronic Endothelia Injury As the earliest step in the pathogenesis of atherosclerosis, endothelial activation and chronic injury, also known as endothelial dysfunction, have been described [16]. The following factors contributed in different extent to endothelial dysfunction and are partly known as traditional risk factors for atherosclerosis [17]: advancing age, dyslipidemia, hypertension, increased levels angiotensin, insulin resistance and diabetes, smoking, estrogen deficiency. Several biochemical pathways have been described for those factors increasing the endothelial dysfunction. Other factors like hyperhomocysteinemia, possible infection and especially low or oscillatory shear stress are still discussed whether they significantly contribute to endothelial dysfunction [18-22]. The phenotypic features of endothelial dysfunction are described as the reduced vasodilator and increased vasoconstrictor capacity, an enhanced leukocyte adhesion, an increase of pro-thrombotic and decrease of fibrinolytic activi ty, and an increase in growth-promoting. (2) Accommodation and Oxidation of Lipoproteins In addition and due the endothelial dysfunction lipoproteins, especially low density lipoprotein (LDL), sequestered from plasma in the extracellular space of the arterial intima. Beside the extent of endothelial dysfunction, this process is depending on the concentration of LDL in the blood circulation [23]. Even so several mechanisms have been proposed for transport of LDL into the arterial intima including vesicular ferrying through endothelial cells, passive sieving through endothelial-cell pores, passage between cells, its not finally understand. However, strong evidence exist, that the accommodation of LDL in the arterial intima is not only a passive effect by a â€Å"leaking† vascular endothelium [REF]. Part of the lipoproteins that have entered the arterial wall stay there and are modified subsequently. Especially the modification of the lipoproteins has a trapping function for die selbigen [24]. The most common modification is the oxidation of lipoproteins, giving rise to hydroperoxides, lysophospholipids, oxysterols, and aldehydic breakdown products of fatty acids and phospholipids. But further modification like fusion of lipoproteins, proteolysis, lipolytic degradation and glycation are well known [25]. Such modified lipoproteins or particles of the modification process have inflammatory potential and trigger a local inflammatory response responsible for signaling subsequent steps in the atherogenesis. It includes a further increased endothelial dysfunction, which may cause a vicious circle of LDL accumulation, and activation of various cell types [24, 26, 27]. (3) Migration of Monocytes and Transformation into Macrophages/Foam Cells More important, the inflammatory response induces migration of leukocytes such as monocytes or lymphocytes into the lesion. Leukocytes are attracted by chemoattractant factors including modified lipoprotein particles themselves and chemoattractant cytokines depicted by the smaller spheres, such as the chemokine monocyte chemoattractant protein-1, interleukin 1 (IL-1) or tumor necrosis factor alpha (TNF-ÃŽ ±) produced by vascular wall cells in response to the inflammatory process [REF]. The activated arterial endothelial cells express a number of adhesion molecules and receptors on their surface, which participate in the recruitment of leukocytes from the blood to the nascent lesion [REF]. Macrophages are a key player in atherogenesis [27]. They develop from recruited monocytes, which migrated as described above into the lesion. In the mediator stimulated process of maturation, those macrophages become lipid-laden foam cells by uptake of lipoprotein particles through receptor-mediated endocytosis [REF]. The accumulation of lipid in the macrophages results in the apoptosis and necrosis, which lead first to a boosted expression and secretion of inflammatory cytokines and second to a release of their lipid excess into a necrotic lipid-core [REF]. Macrophages further produce enzymes, such as metalloproteinases, that degrade the extracellular matrix and lead to instability of plaques [REF]. (4) Adhesion of platelets and Release of SMC activating factors The inflammatory process, especially triggered by the necrosis of the foam cells, microscopic breaches in endothelial integrity may occur. Platelets adhere to such sites of limited endothelial denudation owing to exposure of the thrombogenic extracellular matrix of the underlying basement membrane and form microthrombi. Although most of the arterial mural microthrombi resolve without any clinical manifestation, they lead indirectly to lesion progression by pro-fibrotic stimulation [REF]. The platelets, activated by adhesion, release numerous factors that promote a fibrotic response, including platelet-derived growth factor (PDGF), fibroblast growth factor (FGF), insulin-like growth factor 1 (IGF-1), and transforming growth factor alpha (TGF-ÃŽ ±) [28-30]. Thrombin itself generates fibrin that has a pro-fibrotic stimulus [28]. (5) Migration and Proliferation of SMCs The pro-fibrotic response includes first the migration of SMC from the media of the arterial wall, through the internal elastic membrane, and the accumulation within the expanding intima of the arterial wall. Second, stimulate the proliferation of SMC, which is responsible to form the bulk of the advanced lesion. Another part of the advanced lesions is an increased extracellular matrix. TGF-ÃŽ ± and other mediators stimulate the interstitial collagen production by SMC. These mediators may arise not only from neighboring endothelial cells or leukocytes (a paracrine pathway) but also from the same cell that responds to the factor (an autocrine pathway). Together, these alterations in smooth-muscle cells, signaled by these mediators acting at short distances, can accelerate transformation of the early lesion (fatty streak) into a more fibrous SMC and extracellular matrix-rich plaque. (6) Enhanced accumulation of lipids, collagen and proteoglycans The formation of a complex atherosclerotic lesion is characteristic by an extent remodeling process. Further foam cells within the expanding intimal lesion perish, while they phagocytose more and more lipids. The fibrotic cap between the so arisen lipid-rich necrotic core and the vascular lumen may vary in thickness and allows the classification of â€Å"thin cap fibroatheroma†, which correlates with a higher risk for acute luminal thrombosis [REF]. The production of extracellular matrix, as well plaque evolution and complication can be stimulated by diverse growth factors or cytokines like IL-1 or TNF-ÃŽ ±, and can be inhibited by other cytokines (e.g. interferon alpha (IFN-ÃŽ ±)) [REF]. As atherosclerotic plaques advance, they show intimal arterial calcification [REF]. The same proteins, which can be found in bone, are also localize in atherosclerotic lesions, e.g., osteocalcin, osteopontin, and bone morphogenetic proteins [31]. Both, passive and active models are discussed for the development calcification [32]. SMC can, promoted by several cytokines (e.g. transcription core binding factor ÃŽ ±1), acquire osteoblast-like characteristics and secrete bone matrix [33]. These examples illustrate how the pathogenesis of atherosclerosis involves a complex mix of mediators that in the balance determines the characteristics of particular lesions [REF]. 3.1.1.2 The Role of Inflammation The role of inflammation is central, while those inflammatory mechanisms mediate initiation, progression, and the complications of atherosclerotic lesions [26, 34]. Through the inflammatory process, arterial endothelial cells begin to express on their surface selective adhesion molecules that bind various classes of leukocytes, especially monocyte and T lymphocyte which are found in early human and experimental atheroma [REF]. After monocytes adhere to the endothelium, they can first migrate in the intima, largely stimulated by chemokines; and second transform into macrophages and avidly engulf lipoproteins, largely oxidized LDL [REF]. Although the phagocytosis of potentially harmful lipid particles by macrophages and subsequently the transformation into foam cells has an initially protective, this process involves further expression and secretion of inflammatory chemokines like Interleukin (IL)-1, Monocyte Chemotactic Protein (MCP)-1 or Tumor Necrosis Factor (TNF)-ÃŽ ±. Those enhanc e the inflammatory reaction and enable the further migration of leukocytes into the lesion [REF]. Macrophages also produce toxic oxygen species that cause additional oxidation of the LDL in the lesions, and they elaborate growth factors that may contribute to SMC proliferation [REF]. Similary, T lymphocytes (both CD4+ and CD8+) are also recruited to the intima by chemo-attractants. Cross-talk between macrophages and T cells induces a chronic inflammatory state regarding cellular and humoral immune activation characteristics. This state of a chronic inflammation leads also to the next observed steps in the development and progression of atherosclerosis. Thus, it stimulates the migration and proliferation of smooth muscle cells (SMC), as well the proliferation of vascular endothelial cells in the lesion. Through fibrogenic mediators, released from activated leukocytes and intrinsic arterial cells, the replication of SMCs is getting enhanced and contributes to elaboration by these cells of a dense extracellular matrix characteristic of the more advanced atherosclerotic lesion. 3.1.1.3 Vasa Vasorum and Neo-Angiogenesis The vasa vasorum of the aorta is as a plexus in the wall of artery of microvessels, which are functional endarteries [35, 36]. They either originate from major branches, originate from the main lumen of the aorta or drain in concomitant veins [37]. These vessels allow the humoral communication between intravascular lumen, vessel wall and adventitial layer of large arteries including oxygen and nutrients supply [REF]. Several studies demonstrated that hypoxia [38], cytokines (e.g. vascular endothelial growth factor) [39, 40], pro-angiogenic factors (e.g. hypertension or hypercholesterolemia) stimulate the growth of the vasa vasorum [41]. Those increased microvascular network may contribute to inflammation and lesion complications in several ways. First, the vasa vasorum provides an abundant surface area for leukocytes trafficking and may serve as the portal of entry and exit of white blood cells from the established atheroma. Microvessels in the plaques may also furnish foci for intraplaque hemorrhage. Like the neovessels in the diabetic retina, microvessels in the atheroma may be friable and prone to rupture and can produce focal hemorrhage. Such a vascular leak leads to thrombosis in situ and thrombin generation from prothrombin. In addition to its role in blood coagulation, thrombin can modulate many aspects of vascular cell function, as described above. Atherosclerotic plaques often contain fibrin and hemosiderin, an indication that episodes of intraplaque hemorrhage contribute to plaque complications. Multiple and often competing signals regulate these various cellular events. Increasingly, we appreciate links between atherogenic risk factors, inflammation, and the altered behavior of intrinsic vascular wall cells and infiltrating leukocytes that underlie the complex pathogenesis of these lesions. The present data indicate that vasa vasorum neoangiogenesis and atherosclerosis are seemingly inseparably linked, triggered and perpetuated by inflammatory reactions within the vascular wall. 3.1.1.4 Risk Factors for Development of Atherosclerosis Local shear stress In the coronary circulation, for example, the proximal left anterior descending coronary artery exhibits a particular predilection for developing atherosclerotic disease. Likewise, atherosclerosis preferentially affects the proximal portions of the renal arteries and, in the extracranial circulation to the brain, the carotid bifurcation. Indeed, atherosclerotic lesions often form at branching points of arteries, regions of disturbed blood flow. Age, Gender, HTN, HLP, DM, Smoking, Race/Ethnicity, 3.1.1.5 Atherosclerosis of the Aorta In the characteristic distribution of atherosclerotic plaques in humans the abdominal aorta (Fig. 11-8) is usually much more involved than the thoracic aorta, and lesions tend to be much more prominent around the origins (ostia) of major branches. In descending order (after the lower abdominal aorta), the most heavily involved vessels are the coronary arteries, the popliteal arteries, the internal carotid arteries, and the vessels of the circle of Willis. Vessels of the upper extremities are usually spared, as are the mesenteric and renal arteries, except at their ostia. Nevertheless, in an individual case, the severity of atherosclerosis in one artery does not predict the severity in another. In an individual, and indeed within a particular artery, lesions at various stages often coexist. 2009_Dijk_The natural history of aortic atherosclerosis_A systematic histopathological evaluation of the peri-renal region.pdf 3.1.2 Peripheral Arterial Disease Peripheral Arterial Disease (PAD) is caused by atherosclerosis and represents the most common cause of lower extremity ischemic syndromes in developed countries [42]. Symptoms of PAD are variable including pain, ache, hair loss, thickened nails, smooth and shiny skin, reduced skin temperature, cramp, muscle atrophy, or a sense of fatigue in the muscles. Because of the variability of symptoms, the diagnosis of PDA is frequently missed [43]. In addition, the major part of patients with PAD is asymptomatic [REF]. Beside these diagnostic challenges, PAD affects a large and increasing numbers of patients worldwide. Round 30 million people are diseased in worldwide, but of those only 10 million patients are presenting with symptoms [44]. Further, the prevalence is increasing with age [6, 45], while the prevalence is 10% at the age of 60 years [46]. Association to mortality!!! 3.1.2.1 Pathogenesis of Peripheral Artery Disease The leading cause of PAD is atherosclerosis, especially in older patients (>40 years) and at the lower extremities [42]. Other, but rare causes of PAD include embolism, vasculitis, fibromuscular dysplasia, entrapment, and trauma. Atherosclerotic lesions, which are segmental and cause stenosis, are usually localized to large and medium-sized vessels. The pathology of these lesions is based on atherosclerotic plaques development, as described above (xxx). The primary sites of involvement are the abdominal aorta and iliac arteries (30% of symptomatic patients), the femoral and popliteal arteries (80-90%), and the more distal arteries (40-50%) [REF]. Atherosclerotic lesions have been predominantly observed at arterial branch points. These may be explained by altered shear stress [REF]. However, the involvement of the distal and smaller arteries is more common in elderly individuals and patients with diabetes mellitus [REF]. 3.1.2.2 Risk Factors for Peripheral Arterial Disease While atherosclerosis is the major underlying condition of PAD, the risk factors for PAD are essentially the same as those for other form of atherosclerosis (like e.g. CAD), see Table 1 [47-50]. However, the risk factors smoking and diabetes may have even greater effect for PAD as compared for CAD [51]. Risk Factors Increased risk for PAD Hypercholesterolemia 1- to 2-fold (low) Homocysteinemia 1- to 3-fold (moderate) Hypertension 1- to 3-fold (moderate) Smoking (current and past) 2- to 4-fold (high) Diabetes mellitus 2- to 4-fold (high) Table 1: Risk Factors for Peripheral Arterial Disease 3.1.2.3 Clinical Presentation of Peripheral Artery Disease PAD affects more often the lower extremities (xx times more often than upper extremities) [REF]. The most common symptom of PAD is intermittent claudication, which is defined as presence of pain, ache, cramp, numbness, or a sense of fatigue in the muscles. Those symptoms occur during exercise and are relieved by rest, as result of the increased muscle ischemia during exercise caused by obstruction to arterial flow. Patients with PAD in the lower extremities resulting in ischemia may range in presentation from no symptoms to limb-threatening gangrene. Two major classifications based on the clinical presentations are established, the Fontaine and the Rutherford classification. While the more simple Fontaine classification consists of four stages (Table 2) [52], the Rutherford classification has four grades (0-III) and seven categories (0-6). Asymptomatic patients are classified into Rutherford category 0. Any patient with claudicants are stratified into Rutherford grade I and divided into three categories based on the severity of the symptoms. If patients have pain at rest, they belong to Rutherford grade II and category 4. Any patient with tissue loss are classified into Rutherford grade III and categories 5 and 6, based on the significance of the tissue loss [4]. These two clinical classifications can be translated into each other according to Table 2. Fontaine Classification Rutherford Classification Stage Clinical Grade Category Clinical I Asymptomatic 0 0 Asymptomatic IIa Mild claudication I 1 Mild claudication IIb Moderate to severe claudication I 2 Moderate claudication I 3 Severe claudication III Ischemic rest pain II 4 Ischemic rest pain IV Ulceration or gangrene III 5 Minor tissue loss III 6 Major tissue loss Table 2: Classification of Peripheral Arterial Disease based on the Fontaine Classification in Comparison the Rutherford Classification In the Framingham Offspring Study, the prevalence of PAD was determined in 1554 males and 1759 females from 1995 to 1998.55 The mean age was 59 years. PAD, defined as an ankle-brachial (blood pressure) index (ABI) of ABI Severity of PAD The physician also queried the participant about symptoms of intermittent claudication using a standardized questionnaire [53]. 3.2 Local Adipose Tissue Depots 3.2.1 Variability of Adipose Tissue 3.2.1.1 Anatomy and Morphology SACK: Epicardial, mesenteric, and omental fat all share the same origin from the splanchnopleuric mesoderm associated with the gut.11 Pericardial fat (pericardial adipose tissue [PAT]) is defined as epicardial fat in all these possible locations plus paracardial fat.14 Paracardial fat is situated on the external surface of the parietal pericardium within the mediastinum and has alternatively been termed mediastinal fat.15 Paracardial fat originates from the primitive thoracic mesenchyme, which splits to form the parietal (fibrous) pericardium and the outer thoracic wall.16 Epicardial adipose tissue is supplied by branches of the coronary arteries, whereas paracardial fat is supplied from different sources including the pericardiacophrenic artery, a branch of the internal mammary.17 Lipolysis and lipogenesis have not been measured directly in human epicardial fat. Based on approximately 2-fold higher rates of lipolysis and lipogenesis in guineapig epicardial fat than other fat depots, Marchington et al18,19 proposed that EAT serves to capture and store intravascular free fatty acid (FFA) to protect cardiomyocytes from exposure to excessive coronary arterial FFA concentrations during increased energy intake and, at other times, to release FFA as an immediate ATP source for the myocardium during periods of need. Epicardial fat and the myocardium are contiguous. Islands of mature adipocytes are more frequ ent within the subepicardial myocardium of the RV than the LV13 and may act as more readily available, direct sources of FFA for cardiomyocytes. The thickness of the wall of the right atrium is about 2 mm; the left atrium, 3 to 5 mm; the RV, 3 to 5 mm; and the LV, 13 to 15 mm.20 Possibly, FFAs could diffusebidirectionally in interstitial fluid across concentration gradients from epicardial fat into the atrial and RV walls where EAT predominates and vice versa, but this process in the LV wall can be questioned because the diffusion distance is much longer. Peri-vascular adipose tissue is defined as any adipocytes, which are located close to the vascular wall and has the possibility to secret their biomarkers into the vasa vasora of the wall (see 3.2.1.2). 3.2.1.2 Secretion of Biomarkers by Adipose Tissue Adipose tissue is known to have more functions than lipid storing. Adipose tissue secrets biomarkers and serves as an endocrine organ. Beside hormones, it secrets also different inflammatory cytokines and chemokines. The amount of adipose tissue were associated to xxx, xxx, xxx (FRAMINGHAM?!). Especially peri-vascular adipose tissue like epicardial or visceral adipose tissue demonstrated higher expression of inflammatory biomarkers compared to other adipose tissue depots in the body [REF]. Beside the systemic effect of the secreted cytokines and chemokines, also a local effect/paracrine is hypothesied. Biomarkers secreted of peri-vascular adipose tissue reach over the vasa vasora of the major arteries their adventitia, media, and intima. Therefore it might be involved in the inflammatory process of atherosclerotic plaque. Further, a local effect can be thought by direct diffusion. 3.2.2 Association of Adipose Tissue to Cardiovascular Disease 3.2.2.1 Atherosclerosis 3.2.2.2 Peripheral Arterial Disease 3.2.3 In-Vivo Assessmentof Adipose Tissue 3.2.3.1 Traditional Measures * BMI and WC [54] 3.2.3.2 Imaging-based Assessment * dual energy X-ray absorptiometry (DXA) [55] * magnetic resonance imaging (MRI) [56, 57] * ultrasound [58] * multi-detector computed tomography (MDCT) [59, 60] 3.3 Framingham Heart Study 3.3.1 Historical Origin of the Framingham Heart Study Infectious diseases were prior to World War II the major burden for public health. But through a greater microbiological knowledge and improved sanitation, the morbidity and mortality of infectious disease decreased continuously. When penicillin was introduced in 1942, a dramatic reduction was made in the prevalence and incidence of infectious diseases, especially by controlling tuberculosis and pneumococcal pneumonia [REF]. Replacing infectious diseases, public health was challenged by a mounting epidemic of CVD starting in the 1940s. With World War II over the alarming rise of CVD became increasingly evident. In the United States, 30% of all men developed CVD before reaching the age sixty. The prevalence of CVD was twice of cancer by 1950 and had become the leading cause of death [REF]. Even so the available statistic data from around the world was often crude and inaccurate, it clearly demonstrated a worldwide atherosclerotic CVD problem. Furthermore there was no known treatment to prolong life and to reduce mortality. Added to these distresses was the fact that little was known about etiology, pathogenesis and epidemiology of CVD. The big gap between the enormous public health burden of CVD on the one site and the little understanding of this disease on the other site increased drastically the need for action. At this time, some believed a primary preventative approach was more promising than a search for cures [Dawber, Thomas R. (1980), The Framingham Study: The Epidemiology of Atherosclerotic Disease, Cambridge, Mass.: Harvard University Press.], while the secrets of the etiology of CVD and subsequently for treatment were not being uncovered by basic laboratory and clinical research. Some of these prevention-minded individuals occupied positions of influence and were able to translate their beliefs into actions. The key was to develop a preventive approach, where first of all the characteristics of the host and environment, which lead to the early appearance of the disease, had to be determined. In particular, preventable or modifiable predisposing factors had to be identified. If a practical preventive approach was developed, the hope was that doctors and public health officials would adopt it and so have a widespread impact on the reduction of CVD-based morbidity and mortality. Accordingly to the preventive approach, the Framingham Heart Study was designed given the charge to identify these modifiable characteristics of host and environment for CVD. 3.3.2 Initiation of the Framingham Heart Study By the mid 1940s several striking studies were conducted with an examples epidemiological approach in the fields of nutritional imbalance, metabolic disorders, occupational hazards, accidents, cancer and rheumatic fever under principle investigators (PI) Drs. Dawber, Meadors and Moore [REF, Dawber, Meadors and Moore 1951]. In common, an association between the circumstances and the disease could be identified with-out knowledge of the precise etiology. One of those studies was performed by Dr. John Snow in 1936. He demonstrated that cut-ting off the water supply from contaminated wells, despite incomplete knowledge of the pathogenesis of the disease, stopped cholera. He observed on the one hand the source of the water supply and on the other hand the time and place where the disease occurred. He sufficiently pinpointed based on his observations the major environmental factor for cholera. Further investi

Cambodian American Essays -- Immigration, Southeast Asia

Introduction- Beauty and Darkness Cambodian is one of the newest influxes of immigrants from Southeast Asia. The beauty and the darkness of Cambodia imprinted in history. Cambodia, a country of fertile land and dotted rice fields, of famous and breath taking monuments and ancient temples, of arts and crafts, cultural attractions, and most definitely a history like no other. This is the country that exhibits one of the seven wonders of the world- that is the famous Angkor Wat. Angkor Wat, the largest religious monument that had ever built, significantly in Cambodia. This ancient ruin attracts millions of tourist from all over the world. Unfortunately, set aside all of those captured beauty that Cambodia has, at one point in time in its history; darkness devoured this fragile nation and turned it upside down. This peaceful nation was once ruled by the French as part of French Indochina. With the struggled that Cambodian government undertaken to restore balanced and granting their nation’s independence back from the European colonization, they paid a price. The years of sad and worn out history of this nation’s corrupt government, turmoil, and followed by years of civil war thus making them in a state of dire emergence. Furthermore, with their bordering neighbor’s war, Vietnam, with the United States, Cambodia was slowly dragged into the state of darkness during the Nixon Administration. The Nixon administration conducted secret bombings in Cambodia in the early 1970’s because Vietnam forces had their bases camped in the Cambodian province. As a result of this misleading casualty, it led t o the rise of the Khmer Rouge leader, Pol Pot. His influence gained many fellow native supports in Cambodia. Pol Pot and his entourage brought ... ... occupations are at 17.8%. Sales and office occupations are at 23.5%. Farming, fishing, and forestry occupations are at 0.5%.

The Kalapalo Indians :: essays research papers

The Kalapalo Indians The Kalapalo Indians of Central Brazil are one of a few surviving indigenous cultures that is uniquely protected by a national reserve in lowland South America. Through no effort of there own, they have been isolated artificially from Brazilian social and economic influences that reach almost every other Indian tribe in Brazil. This unusual situation has made it possible for the Kalapalo’s culture to be undisturbed by the outside world and the surrounding tribes. Much of Kalapalo life is run through a central concept or an ideal of behavior, called ifutisu. This is an infinite ideological concept that is represented in many ways in social life and ideal organization among the Kalapalo. The area in which the Kalapalo live is in the northeastern Mato Grosso state called Upper Xingu Basin. There are four unintelligible languages by groups in this region. This makes the Upper Xingu Basin linguistically diverse, but with many of the groups still sharing the same social and ideological features. It is very difficult to trace back the origins of Kalapalo life because of the integration of the many different and culturally diverse groups in the Upper Xingu Basin. So, many of systems of kinship classification, marriage practices, ceremonial organizations, status allocation, and religious beliefs are consistent with cultural rules and social practices and not with the original system. Many of the modern local groups can only reconstruct their own history which is in limited detail, these systems can’t be isolated completely from the existing society. The two most important social units in Upper Xingu society are the village and the household groups. Both the village and household can be considered corporate in that both control rights to territorial resources, acts as a unit when performing certain economic and ceremonial activities. Members of a household group are obligated to pass out food which they collect amongst themselves. Even when one cannot supply food a Kalapalo is assured of a share because everyone is treated with the same kind of respect. Despite this corporate organization, membership in villages and households is constantly changing, and there is much movement of people between group to group. The Kalapalo society is a system wherein social units, such as the village groups and households exist only because of the individual who decides to live in these systems and choose to cooperate with one another. This is very different from other non-western societies whereas the individual acquire the responsibility to join in social units, by birth or other means of relationship to and with each other regardless of the identity of the individual themselves. The Kalapalo social organization is characterized by a flexible group membership
