Invasion of the Drones Essay

The constitutional issues that the people have raised on drones are the right to privacy, which is guaranteed in the fourth amendment. The Fourth Amendment protects against â€Å"unreasonable searches and seizures. † It guarantees Americans’ right to privacy and requires police to obtain warrants or have â€Å"probable cause† to search someone’s property. This could violate the constitution because should police be require to obtain warrants to take photos and collect other information with the Drones? Then in the Fifth Amendment it guarantees Americans accused of crimes the right to â€Å"due process† under the law. The accused are entitled to a legal representation and to see the evidence that’s being used against them. This could violate the Constitution because drone strikes aimed at killing American terrorist suspects in foreign countries could violate the Amendment. I share the concern for the violation of the Fourth Amendment, because I would feel that I’m under watch all the time, and that at any time the Police could be collecting information or taking pictures of me because they have the equipment to do so. Then what if they used these pictures and information to give them a probable cause to search my house, but they didn’t find what they were looking for. The technically violated my privacy for no reason. When most people hear the word drone, they probably this of how the drones have been used in the last decades. Which were the drones were used to kill suspected terrorist in hot spots like Pakistan and Yemen. Or one particular incident that attracted a lot of attention was in September 2011, the C. I. A. drone strike in Yemen killed an American citizen, a radical cleric who preached holy war, which violated his Fifth Amendment rights. This might affect the public’s receptiveness to the domestic use of drones because a new federal law paved the way for drones to be used commercially in the U. S. nd made it easier for government agencies to obtain them. The Department of Homeland Security even offered grants to help local authorities buy drones. Various sensors, included cameras can even be attached to the drone. Senator Patrick Leahy said that this fast-emerging technology is cheap and could pose a significant threat to the privacy and civil liberties of millions of Americans. It is another example of a fast-changing policy which we need to focus to make sure it is used correctly.

Black Power Movement Usa

Cultural Diversity Black Power From the start of our country African Americans had been beneath white society. The civil rights movement of the south put an end to segregation and gave African Americans the same rights as an Anglo American legally. Racism and black segregation were still very much alive though, and if African Americans were ever to be treated as equals they would need to liberate from white society and truly empower themselves. This was the Black Power Movement. The movement for Black Power started during the civil rights movement in the 1960s.The movement was made up of several different organizations and spoke persons with a variety of ideas and views differing from that of Martian Luther King and the civil rights movement. They felt that the civil rights movement to end segregation was not enough and many black power advocates rejected the civil rights movements’ ultimate goal of assimilation. They believed that white racism and institutional discrimination would always be a part of American culture and society, and did not want to be integrated into the very system that for centuries oppressed, denigrated, and devalued blacks.The Black Power movement was built around ideas of racial pride and Black Nationalism with groups working to increase African American control over schools, law enforcement, welfare programs, and other public services in black communities. They felt that to be equal they must liberate and truly empower themselves on there own terms in order to gain power and stand up to the dominant group. Advocates of Black Power were open to the use of violence in order to achieve there goals, which was in direct contrast to the non-violent approach demonstrated by Martin Luther King jr. ,leader of the civil rights movement.The first popular use of the term Black Power as a social and political slogan came from Stokely Carmichael, an organizer and spokesperson for the Student Nonviolent Coordinating Committee (SNCC) a group as sociated with the civil rights movement. The SNCC was made up mainly of younger members who over time became more violent and outspoken in the belief of Black Nationalism. During the civil rights’ March against Fear there was a division between those aligned with Martian Luther King jr. and those aligned with Stokely Carmichael each having there own respective slogans of â€Å"Freedom Now† and â€Å"Black Power†.During the March a man by the name of James Meredith was gunned down and Carmichael is quoted in saying â€Å"This is the twenty-seventh time I have been arrested and I ain't going to jail no more! The only way we gonna stop them white men from whuppin' us is to take over. What we gonna start sayin' now is Black Power! † From then on the SNCC was for the Black Power movement and Black separatism from whites. The goal of Black Nationalism was also held by the Black Muslims a religious group under the Nation of Islam fighting for Black Power.The Bla ck Muslims were a well known organization within the movement. They were angry, impatient, outspoken, and did more then just talk. There goal was to develop the black community economically in order to supply jobs and gain capital solely by using their own resources, which would help them deal with the white society from a more powerful position. One of the best leaders of the Black Muslims and of the Black Power movement was Malcolm X. He was a very well known and heard man who studied under Elijah Muhammad, the leader of the Nation of Islam.Malcolm X believed in black independence from white society and brought his strong views against white racism and discrimination to the public eye more so then maybe any other leader of the movement and became a threaten figure to white America. Malcolm X was later assassinated in 1965 not due to conflicts with white society, but due to conflicts within the Nation of Islam, specifically those dealing with leader Elijah Muhammad. The SNCC and Bl ack Muslims looked at white society as one and in turn formed there own racism and prejudice to all whites and believed in Black separatism and Black Nationalism.The Black Panthers however were a well known group of the Black Power Movement and believed in neither Black separatism nor Black Nationalism. Huey P. Newton and Bobby Seal, founders of the Black Panthers believed in creating a political group for the people, one that would stand up for the opposed against those who oppose them. They felt the national government not white society was holding them down and the struggle for blacks came more from economic exploitation then from racism.Here is a quote from Bobby Seal as writing in his book Seize The Time â€Å"In our view it is a class struggle between the massive proletarian working class and the small, minority ruling class. Working-class people of all colors must unite against the exploitative, oppressive ruling class. So let me emphasize again — we believe our fight is a class struggle and not a race struggle. † Huey P. Newton and Bobby Seal believed in something bigger, something along the lines of a revolution with the strength of numbers and will power of the people leading the way.Newtown and Seal received much harassment from law enforcement because of this message, so much so that Newton was convicted of killing a police officer and thrown in prison causing much uproar in the legions people he stood up for. The Black Panthers are still very much alive today and continue to stand up for the people. Here is a statement from there website, â€Å"We know now, more then ever before, that the will of the people is greater than the technology and repression of those who are against the interests of the people. Therefore we know that we can and will continue to serve and educate the people†.All three of these groups had significant role in the black power movement and there anger and aggression both directly and indirectly helped pa ve the way for black politics. The National Black Political convention was held March 10-12 1972 in Gary, Indiana and was a huge milestone for black politicians to come and we now have a black man in office. In close, looking at the situation I feel there are both pros and cons. I believe the movement for Black Power helped open the worlds eyes to inequality and inspired movements to come such as women’s rights, red power, and gay/lesbian rights to name a few.The movement gave the black community a sense of pride to be black and helped cure the pains left by years of slavery and segregation. In turn though this caused more racism both from blacks and whites alike due to such a strong emphasis on race and black segregation. This racism is still easy to see in present time, although the discrimination is definitely lower. I believe if the civil rights and Black Power movements could have worked as one, things would have turned out better for the black community overall.This is an image of Tommie Smith and John Carlos, two American track athletes who placed first and third respectively giving the Black Power salute on the podium at the 1968 Olympic Games in Mexico City. This caused great controversy and both were kicked out of the Olympic village and were expelled from the games by the IOC. Both men were booed by the crowd when they left the podium and Smith later stated â€Å"If I win, I am American, not a black American. But if I did something bad, then they would say I am a Negro. We are black and we are proud of being black. Black America will understand what we did tonight†.Bibliography . Black Panthers, www. BlackPanther. org .

Williams Syndrome in Psychology Research Paper Example | Topics and Well Written Essays - 1750 words

Williams Syndrome in Psychology - Research Paper Example Yet, another similar condition can be compared with Down Syndrome, the Williams Syndrome--also known as William-Beuren Syndrome. Rare in characteristic, this type of syndrome was first recognized in the early 1960’s, where four young samples had been identified with such conditions, as all had presented â€Å"supravalvar aortic stenosis...mental retardation† and similar facial features. By such discovery, the said disorder had been named in honor of one of its founder, Dr. Williams--a cardiologist (Bellugi, Wang, & Jernigan, 1994, p. 3). Other than these initial diagnostic parameters, Williams syndrome is also characterized by hypercalcemia of unknown origin, accompanied by distinct cognitive and behavioral profile (Khan, Calureriu, Huang, & Robin, 2011). At this point, such concepts seemed to be more focused on the pathophysiological context of the said condition, disregarding the psychological elements of William syndrome. In appeal, this group is said to be hypersoci able, where they are into over-friendliness, as they appear to lack the adaptive behavior of covertly following the unwritten social rules common in most societal structures (Udwin, Davies, Howlin, & Stinton, 2007). With such social trait, one can assume that the interpersonal skills generated by individuals with William syndrome are adequate for daily public associations, yet, a number of literatures presented otherwise. The overtly sociable attitude by groups with William Syndrome may be acceptable in society, but their psychological status may not be as stable as most believed. This paper seeks to establish the paradoxical traits that individuals with Williams Syndrome seemed to have; present common psychological features and find patterns among such psychological manifestations. Biological Origins and Clinical Features The etiologic origins and pathological process seemed to be pointed back to genetic deficits. Generally thought of as a neurodevelopmental condition, most experts identified the â€Å"deletion of ~25–30 genes...(which span) about 1.5 megabases in the q11.23 region of chromosome 7† as the exact cause of the William Syndrome (Deutsch, Rosse, & Schartz, 2007, p. 903). Genetic in function, such dysfunction in the genetic level can significantly cause a series of physiological changes upon human anatomic development, especially in organ tissues of the heart. As this is genetic in origin, the defective genetic material is said to have a hereditary feature, where there can be a 50% chance that individuals might pass this DNA product to the next generation. Although random in pattern, studies showed that 1 infant in every 80,000 births can have this syndrome--a highly rare occurrence (â€Å"William Syndrome,† 2011). Like most genetic disorders, people with such condition can easily be distinguished due to their common appearance, where their faces may have an elfin quality, with prominent forehead and eyes, ample cheeks, expansi ve mouth, small nose, and broad earlobes (Semel & Rosner, 2003). In line with this, overall presentation of the condition can be divided into four sections: â€Å"cognitive development, language, auditory function, and visuospatial function† (Khan, Calureriu, Huang, & Robin, 2011). In context, cognition and language functions are quite delayed for their age, with highly sensitive hearing capabilities to auditory stimuli, and a disassociation between what is seen and its normative interpretations. As such, environmental adaptation of these groups is delayed, compared to their normal counterparts. Aside from these clinical symptoms, those with William Syndrome are also plagued with a number of medical disorders, which may range from clinically serious cardiac

Global warming Research Paper Example | Topics and Well Written Essays - 2000 words - 3

Global warming - Research Paper Example This document will examine how human beings are contributing to global warming. There have been many studies on the topic of global warming, but experts say that humans are the cause for the drastic climate changed going on around the world due to resource consumption, resource disposal, and population growth. According to Watts (2007), human activities have influenced the atmospheric temperatures across the globe. The rising global temperatures have become an issue of concern due to the impact it has on animal and plant lives across the globe. Increasing human population has resulted to increase in consumption and generation of materials and all contribute to global warming (Casper, 2009). The climate change has affected the activities of human by changing the land use and human struggle to reverse the situation. The understanding of how man has contributed to global warming can be gained by considering the impact of the human population, consumption and disposal of waste influence the atmospheric temperatures (Watts, 2007). Also, the knowledge is essential because it can direct organizations and the states to design policies that can regulate human activities hence reducing global warming. According to Casper (2009), there is an increasing global demand for energy and other commodities both processed and unprocessed goods. Developed nations are the major consumers of fossil fuels hence they are leading in greenhouse gas emissions. For example, the United States has about five percent of the world population but contributes about twenty five percent of carbon emissions in the globe (Murtaugh & Schlax, 2009). Murtaugh and Schlax (2009) further argues that the United Nations Population Fund suggested that, by the year 2050, the world growing economies such as India and china will contribute more than fifty percent of the carbon emissions. The level of emission of greenhouse gas

Garden art through the ages Article Example | Topics and Well Written Essays - 750 words

Garden art through the ages - Article Example Art history has the major objective of determining the originality of various works of the art. Anciently, anything produced using a machine would not qualify as art but in the modern time the scope of the study has increased including the study of computer aided images. The history of art depends on the artifacts. There is an established way of generating a date when a given art was done based on a certain artifact that is available. The artwork was done a long time ago, but the artifact is a presentation of the evidence of the artistic activity that took place. There are certain questions of concern to the art historian, and the first question is the age of the art. The dates when the artwork was done can be established in a number of ways. The historian can use the physical evidence of the material that was used to decorate a particular artwork. For example, certain paints then he or she can easily guess the age of the artwork from the existing artifact that is based on a given fact that the given material that was used did not exist at a certain time anciently. Therefore, the historian can easily trace the age of the art by checking on the artifact that is existing. An earliest possible date and latest possible date for the use of certain material such as certain type of inks can be established by the historian. There are materials that are used by artists at the current time and those that were used in the olden times and therefore it becomes very easy for the historians to come up with a conclusive age of the artwork based on material used to construct the artifact. The historians also rely on documentary evidence. This is because it provided a hint of the date when a given article was written about a certain artwork that manifests in the form of physical artifact that exists. This means that if a historian wants to know the age of an artifact, he or she only looks for the historical books where the ancient artists

Social Class Essay Example | Topics and Well Written Essays - 1000 words

Social Class - Essay Example These classes are â€Å"distinguished by inequalities in such areas as power, authority, wealth, working and living conditions, life-styles, life-span, education, religion, and culture† (Cody). How one’s socio-economic status, with which he is born with, affects his life chances is going to be discussed in this paper. Let’s first talk about healthcare. One who is born with high social status is given all the rights by the society to enjoy good health care facilities. He has enough money to go to expensive doctors or even visit physicians abroad. He has all the resources with which he can afford expensive medicines, and also can hire servants who bring the medicine placed on a tray to be put into his mouth. When a wealthy man goes to a hospital, he immediately gets an appointment with the highly professional provider. On the other hand, when a person belonging to a lower class, or even a middle class, gets sick, he is not able to afford to go to a doctor and buy c ostly medicines. If at all he manages to reach the hospital, he has to wait in long queues to get an appointment to get him examined. The doctor will not talk to him humanely. This way, the upper class enjoys greater longevity than the lower class. The middle class is not affected much in case of longevity. Hence, the amount of money a person has in his pocket decides what kind of and how much health care he will receive. This is the class discrimination that has deepened its roots into our society and no matter how much we get educated, we will always fall prey to this cruel discrimination. As far as family life is concerned, it is affected negatively in lower classes. This is because poor people are more stressed out because of poor financial conditions. They do not have high paying jobs, and thus they hardly make both ends meet. They cannot think of any luxury other than earning bread and butter. The family life is disturbed and the children do not get enough attention from their parents. Despite being the richest country, Americans rank highest in child poverty rates. They are stricken with insufficient nutrition along with unemployment and housing that is overcrowded (Arloc). Poor class manifests in physical, emotional and social ways. McLoyd suggests that impoverished children have social, emotional and behavioral problems due to poor health and serious mental health problems stemming from the persistent poverty level in which they live. Aber and Bennett concluded that serious health problems come along with the territory such as preventable diseases like Influenza, Measles, Malnutrition and AIDS due to lack of proper education and poor or no health care at all. On the other hand, the rich people have all the facilities and luxuries with which they can make their lives easier and their children happier. They can always spend lots of money on vacations, movies, games, picnics, and so on. The education and the political system is also dependent upon the so cial class. Lower social classes do not have the funding to support their children financially so that they are able to get good education. So they lag behind. This ends in their not getting good jobs, thus they add to the overall poverty. The high social classes can afford good schools and colleges, and can even send their children abroad for higher education. Thus, education sector is controlled by those high in power and wealth. Moreover, upper class is also able to vote more and choose their political leaders. Lower classes either

Divorce as a Social Issue Essay Example | Topics and Well Written Essays - 2000 words - 1

Divorce as a Social Issue - Essay Example r, the belief in religion and ethics or morality are diminishing at present because of the advancements in science and technology and changing life styles and life philosophies of people. Family concepts have less value in contemporary American society which motivates the people to change their husbands and wives just like changing their dresses. This paper briefly analyses the different dimensions of divorce and the major impacts it may cause to the society and family. Cruel treatment, Impotence, Inebriation, Adultery, Desertion etc were the major reasons for divorce in America during seventeenth century. But in twentieth century, the reasons for divorce changed a lot. Loss of sanity, Instances of incompatibility and Long term separations were the reasons of divorce during the initial half of the twentieth century. However, the reasons of divorce kept on changing and during the latter half of the twentieth century; Increase in the earning potential of women, more social acceptance of divorce, an enhancement in the pursuit of joy (i.e. the possibility to locate a better partner) and the presence of no fault laws were the motivating factor for divorce (History of Divorce in America). The above facts clearly show that the reasons for divorce during ancient centuries were biological or behavioral and more genuine when we consider the reasons for divorce in the present century. Divorce laws were tougher earlier compared to that of the current divorce laws which forced people to think about a divorce only in the extreme cases. However, most of the current divorces are taking place because of silly reasons. Even the husband and wife do not know the exact reasons for their divorce. According to Winchester & Beyer (2001); â€Å"during and after divorce, many parents feel guilty and confused† (Winchester & Beyer, p.47). This because of their lack of awareness about the reasons of their divorce and the possible consequences divorce can cause in their future life. â€Å"Around

Stalins Leadership in World War II Essay Example | Topics and Well Written Essays - 3000 words

Stalins Leadership in World War II - Essay Example The second half of the 1930s saw the continuous campaign launched by Stalin to eliminate all those whom had - or at least were suspected to have - reservations about the political regime. The campaign that would become known as the Great Purge touched off immediately assassination of Sergey Kirov, a highly popular member of the Communist Party. Stalin responded to the assassination with a series of fierce actions. Mere distrust of Stalin or his confidants or anonymous information was used to send the suspect to the forced-labor camps or execute. The Soviet political militia, also known as NKVD, was given practically unrestricted powers, and during only two years from 1937 to 1938, the NKVD led by Nikolay Yezhov executed approximately 1 million of Soviet citizens with another 2 million were sent to the camps and eventually died (Ellman 2002). Several trumped-up trials that took place between 1936 and 1938 led to elimination of thousands of once prominent, influential and highly experienced leaders. The list of victims included such outstanding figures as Zinovyev, Bukharin, and Rykov whom were executed on concocted charges of conspiring with Germany and Japan. Another process held in 1937 resulted in almost entire elimination of the military's top-ranking commanders such as Marshal Tukhachevsky: according to the estimates approximately 50 percent of the senior officers had been dismissed (partially executed, partially sent to the camps) before the beginning of the Second World War (Conquest 1990). Evidently, such actions of Stalin who killed or sent to the camps the most experienced and talented managers could hardly be addressed as prudent in the face of inevitable war with Germany. Although Stalin's awareness of the inevitability of the war is subject for intensive debates (Rapoport & Alexeev 1985), it is difficult to imagine that a politician of Stalin's rank and experience could fail to notice the apparent tendency. Even the possibility that Stalin could make the mistake assessing the beginning of war hardly justified such devastating clean-up among the militaries, officials, and political elite of the Soviet Union. Furthermore, a series of conflicts initiated by Stalin in 1939 (Finland) and 1940 (Latvia, Lithuania, Estonia, and Romania) clearly demonstrated that the Soviets were confidents of their military power. Ironically, what might be and probably had to be perceived as imprudence by the absolute majority of Stalin's contemporaries only adds validity to the claims of those whom give credence to his personal leadership during the World War praising Stalin as the leader and tactician of the highest order. The fact is that in absence of other leaders of note whom had been dismissed, imprisoned or executed during the Great Purge Stalin was forced to make decisions almost solely on his own: even those innumerous specialists whom successfully made it through the terror of 1937-1938 had the illustrative example of what Stalin did to

Communication in media Essay Example | Topics and Well Written Essays - 3000 words

Communication in media - Essay Example In addition to this, the growth in the Internet sphere has been phenomenal. The European Union along with United Kingdom has been one of the first few to recognize the rising problems in this sector and the need to control the media and its happenings. In addition to these technology changes, it is also found that there is a growing convergence of all the technologies. Every one of these services is available on any of the media that is needed by the user (European Commission, 1997). Controlling and monitoring the changes that are happening in the industry is becoming more important. This paper would review the nature of changes that have come about in the industry and the need to control and monitor them. It explains the effective ness of the control that is already in place in UK in the form of Ofcom and what are the major lacunas in the controlling mechanism. Though UK and the media all over the world has been talking of self-control, frequently media has overstepped its brief and has trespassed into the private domain. Ofcom was launched as a regulatory authority to ensure that adequate and appropriate control exists in the wireless sector as well as to ensure that the media does not trespass into private domain and sink the liberty of the individual in the name of media liberty. Regulation is required to also ensure that there is no chaos in the wireless world. With new medias like the telephones getting highly personal, the infringement of private domain is happening too frequently. This necessitates regulation. 3. History of Regulation in UK and Europe 3.1 Early Regulations on Media Media regulation in UK started in the form of a Press Complaints Commission, which was an independent body that was working on the various complaints and issues that came about the press reports, and accuracy of the information or the personal infringement it caused. By June 1990, government's Committee on Privacy issued a report that made clear submissions about the pseudo independence of the Press Complaints Committee and reported reservations on the way the press and the media worked (Laurence Raw, 1998). Government at that time issued a stern warning to the press to organize themselves if they did not want government to interfere in their working. By 1993, the second committee recommended an ombudsman for taking care of the press invasions into privacy and also a Press Commission that would monitor the press freedom as well as ensure that the limits are not surpassed. However, the government passed regulations as a part of the civil law to restrain press from 'spying, prying, watching and besetting' into the private affairs of an individual citizen. The other regulations on the broadcasting media were the Broadcasting Acts of 1990 and 1996. 3.2 Regulation of Television in UK and Europe 1990s also saw massive changes sweeping the European Union as well. Television without Frontiers (TWF) and Open Network Provision (ONP) form the core of the early regulation regime in Europe. When the regulation was introduced, it invoked negative reaction from the industry, which foresaw the reentry of controls in the industry as the form of regulatory mechanisms. The 1989 'TWF' regulation paved way for viewing television as a service and one that could transcend the national borders across the

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

The Crucible - Important Character Analysis :: Arthur Miller

In The Crucible, Arthur Miller establishes the universal theme that good does not always prevail over evil. It shows that fear and suspicion can produce a mass hysteria that destroys public order and rationality. This theme is clearly identified through the character's actions throughout the play. Three characters in the play demonstrate different types of human condition through the decisions they make. Reverend Hale and John Proctor represent the human condition to choose rationally while Danforth advocates a more traditional side. All but Danforth have a change of heart from the given situation. The Crucible argues that even when a society is corrupt, a person with high moral character can follow their conscience to make a good decision. Reverend Hale is called to Salem to help solve the witchcraft chaos. At first he is confident in doing his job as a reverend by following the church standards. He agrees with the court?s tactics, which involves searching for confessions to aid the trial in sentencing people to death. Over the course of the play he experiences a huge transformation. As he listens to both sides of the trial, he realizes that the church and court standards may be wrong, and he begins to question these standards within himself. He stops supporting the court because he can no longer accept the false prosecutions that Danforth continues to make. His final decision in going against the church and following his heart shows the true side of his character. He goes through the rest of the play trying to save people?s lives. When someone asks why he has come back he states, ?Why, it is all simple. I come to do the devil?s work? (986). This shows he feels that doing what may seem wrong to others is actually the right thing to do. His efforts are in vain, however, because in the end the Puritan Court overrules all other opinion. Danforth is the judge of the witch trials and is very stubborn in his ways. His handling of the trials is overbearing and intolerant. He is shocked when Francis Nurse dares to judge his authority and states, ?Peace, Judge Hawthorne, do you know who I am, Mr. Nurse (959). He thinks that he is superior to everyone else and he believes he has the best judgment of all. Because of his job he is feeling pressured to please the majority of the people.

Jane Eyre :: essays research papers

In the two stories, Jane Eyre and The Yellow Wallpaper, the main characters are faced with various encounters with authority. Jane and the Narrator are the central characters that are faced with these authority figures, and an external as well as an internal relationship is developed with the figures that have power over them. These two women also display a unique use of authority to benefit themselves at various points in the stories. Jane and the Narrator are first alike in the way that they outwardly express their feelings about the situations they are in by the use of actions and words. This open, verbal communication with these figures in their lives is a common trait between them, but what differs is that Jane's communication is positive (she gets her feelings in the open and is understood) and the Narrator never gets listened to. The second similarity between Jane and the Narrator is the inner attitude that they feel about the figures of authority. This attitude is present in both characters as the reader sees their inner thoughts and feelings as well as the words and actions that take place when the authority figures are not around. The last criterion that is common to both Jane and the Narrator is that each woman gains a power of authority near the end of their story. What differs between the two is how they go about possessing the authority, and how they use it when they finally have it. The end result is made up of similarities between the two women's characteristics, but differences in the way that they use those characteristics in their lives. The novel Jane Eyre is about a young girl who goes through her life struggling with various life issues. Jane encounters people that treat her with little respect, the feeling of being trapped in situations that she is not happy in, and learning how to grow up as a poor girl who has to make all of her own decisions without any help.  Ã‚  Ã‚  Ã‚  Ã‚  A significant starting point in the novel Jane Eyre is at her arrival at Thornfield, and her meeting with Mr. Rochester. At that estate Jane is employed as the governess of a small child named Adele. At this point in Jane’s life, she is learning what it is like to be a paid subordinate under a master. This proves to be a good learning experience for Jane, and as the character of Rochester goes on to shape her life as she stays there, Jane learns and grows along with her feelings.

Cognitive Behavioral Therapy (CBT) and Management of Anorexia Essay

Introduction In this paper, I will discuss how cognitive behavioral therapy (CBT) can be utilized in the management of eating disorders. More specifically I will identify Anorexia Nervosa and provide statistics that relate to the disease. Etiologies will be discussed as well as symptoms. Various techniques of Cognitive Behavioral Therapy will be described as well as the rationale as it relates to the clinical issue. Therapy has been used for many generations as a mean to resolve dilemmas in a persons’ life. Unfortunately, due to cultural aspects, therapy is generally centered on an individual. We typically presume that any problem that one may exhibit can be solved through personal realizations. However, society and therapists alike are beginning to understand that circumstances we encounter and actions we exhibit are directly related to our environment. Family therapy focuses on interactions. There is no distinguishing factor that manifests and leads to a condition or disorder. No one plays a particular good or bad role. Relationships are a key factor in family therapy (Nichols, 2009). Family Therapy Model –Cognitive Behavioral Therapy Cognitive behavioral therapy (CBT) is a modified therapeutic care plan that integrates various components of cognitive therapy and behavior therapy. Cognitive therapy examines the way a persons perception of themselves as well as their perception of others affects their mental psyche. Behavior therapy investigates particular behaviors and interactions with others. CBT can be used in parallel to appropriate medicinal treatment to examine how modifications in behaviors and thoughts can enhance the quality of life.

Does marketing create or satisfy needs? Essay

When we talk about marketing, there are lot things that we should know first. Marketing is activities of creating value that desired by the potential buyers and receiving value from the potential buyers for the value that they have received. When marketers want to create something that has value to the potential buyers, marketers must know first, what do the potential buyers need or want. As a marketer, it does not make any sense if we sell something that does not have value, or if the marketers want people to purchase something that they do not need of even want. Marketers can not force anyone to do something. They can only ask them to buy their product or service. Some people might not care about what they are asking for. So, in the business of selling product or service, we know word â€Å"marketing†. Marketing is an art of identifying and meeting the people’s needs and wants. It is all about communication between two parties that profitable for the both sides by exc hanging value. Marketing is not that easy to do. As we know, we can not mess with the â€Å"free will† of the people around us or people that we see as the potential buyers. It is up to them if they are willing to buy the marketers’ products or service. In this case, the marketers have to do their marketing activities. Their job is to tell people that their product or service is suit with the people’s need or want. Therefore, the marketers have to know what do people need or want. How can the marketers find out about what the people need or want? They analyze the potential buyers. They have to collect data about the potential buyers. The data is all about their behavior and so on. Anything that can help the marketers to make the potential buyers recognize their product or service and tell them that they should buy it because it is something that they need or want. Products and services can not be created or even sold if people do not need or even want them. So, the data about t he potential buyers’ behavior is important. When the marketers analyze the data, they can tell if their product or service is desirable or not. In the marketing, we know â€Å"4p’s†. 4p’s are product, place, price, and promotion. First is product. It means that in order to make the potential buyers purchase the marketers’ product or service, they have to create a product or service that has desirable value. In another word, a useful product must be created for the potential buyers. Second is place. When the marketers want to sell their product or service, they have to consider the place also. Place that geographically potential to sell the product or service. Selling product or service at a wrong place can bring the marketers to the misery of loss. It can happen because place or environment can affect the ways of thinking or the behavior of the people in it. Different place means different need and want. Kentucky Fried Chicken (KFC) recognize the need of Indonesia people for chicken that being eaten with rice. So, unlike in the other countries, they sell not only fried chicken, but also rice in In donesia. So, it is an important thing to consider the place to sell the product or service. Third is price. When the marketers sell their product or service, they have to set price that suit with their product or service. For example, we can not sell T-shirt at a price of $10,000. It will make sense if what we sell is car. So, the marketers have to set the price based on the value they are offering to the potential buyers. Nowadays, discounts can make the product or service being purchased. Setting the lowest price to pull the potential buyers is becoming trend to many companies. The last one is promotion. Talking about promotion is all about sending message to the potential buyers. The message tells the potential buyers that they need or want the product or service. That is why they have to buy it to fulfill their need or want. Promotion can be in any forms. The product or service can be promoted in commercials, banners, and any other media. The message must reach the way of thinking of the potential buyers or even their heart. Whatever it takes to make them desire and purchase the product or service. To sell the product or service, any marketers have to really consider about the 4 p’s. As we know, nowadays, people are independent and have their own thought. So, marketers have to think hard in order to reach a lot of people. But only reach people, but they also have to pull people to recognize and purchase the product or service. We can not avoid the fact, different  person, different personality, different thought, and different perception. What the marketers think is not the same as the people think. The way people think is influenced by the environment or the society around them. Places with different cultures must have different kind of people. Culture influences people time after time. So, it is something that can not be easily erased or changed by any marketers. And people with different kind of family backgrounds and different kind of friends must have different perception or way of thinking. People or group around the potential buyer influence their way of thinkin g and sometimes help them to decide what do they need or want. So, any marketers can not underestimate the 4 p’s. The needs and wants of the customers are differently created because of factors, such as cultural factors, social factors, and personal factors. First, cultural factors like the cultures around the customers create several certain needs and wants. Mostly, the culture in a country is different from the other countries. In a culture of a country, people have a different perception and way of thinking than people in the other country. It is a fundamental determinant of the marketers’ opportunities to enter the market. The second is social factors, such as reference group, family, role, and status. As we know, people around the customers are influence the way of thinking or perception and the behavior of the customers. We also know that people with different roles and status must have different needs and wants. For example, a person with a role as a governor needs a security. Unlike the common people who do not need any added security need. High status people usually purchase more than low status people. The high status people might need an expensive brand like Armani to show other people that they have a high status and power. Unlike the common people with middle to low status. They do not need more than a well known brand like Zara or something like that. As long as they are wearing an outfit that looks good on them. The third one is personal factors, such as gender, age and life cycle, economic circumstances, and lifestyle. Gender is really matter to create needs and wants. Women and men have different perception and circumstances. Women routinely need cosmetic to make them look good. But men do not need any cosmetics. Age and life cycle of the customers determine their need. A person in age 1 up to 2 or in ‘baby’ life cycle needs nappies. But a girl in  age 16 or in ‘teenager’ life cycle needs tampons. Economic circumstances of people are also determining what do they purchase. People with a good economic circumstance can recognize more needs and wants and purchase more than the other people. Next is lifestyle. It is obviously that lifestyles of the customer influence their behavior and they can also recognize their need and want. Because of their lifestyle, people purchase different thing with the other people. Lifestyle is a person’s pattern of living in the world as expressed in activities, interests, and opinion. For example, mostly of the people with a healthy lifestyle do not purchase junk foods. They only purchase fresh foods. So, they basically create their need based on the way they are thinking and their own perceptions. We can think of marketing as a way of making sure the customers have the right types of product and service experiences to create the right brand knowledge structures and maintain them in the customers’ memory. In practice, marketing is following the logical. First, marketers have to analyzing their opportunities, and then they have to select their target market. Market is a group of consumers or potential buyers. Marketers select the market which is desire their product or service, because they need or want it. Targeting market is about targeting people who do you think want to buy your product or experience your service. In practicing marketing in the target market, marketers also have to consider the four dimension of SIVA. SIVA contains of solution, information, value, and access. These are the questions of the customers that are designed to be answered in order to make the benefit exchange between the customers and the marketers. Solution : How can I solve this problem? Information : Where can I learn more about it? Value : What is my total sacrifice to get this solution? Access : Where can I find it? The dimensions above are the basic questions that must be answered by the marketers. So, to attract the customers, marketers must tell them that they can solve their problem. Somehow, the marketers must communicate with the  customers and make them sure that the marketers are really care about their problem and also care to solve it. In communication, marketers not only make the customers recognize their care, but also recognize the capability of the marketers to help the customers. The marketing process cans not being processed without any push by any means from the customers. Marketers are developing the marketing plan by analyzing the customers’ behavior or customers’ environment first. Any strategies that created are basically reflected by the data of the customers and their environment. Marketers communicate with customers in order to find out what do they need or what is their problem and tell them that marketers can fulfill it and also solve their problem. So, we can say that Marketing is reflect the needs and wants of the customers and happening in order to satisfy customers’ needs and wants. There is no way a company creates a useless product or service. There must be reasons and goal to reach when a company creates product or service. The marketing plan that developed by the marketers simply reflected by needs and wants of the customers. Marketing exist in order to satisfy the needs and wants of the customers. There is another thought that say ‘Marketing shapes or create the need of the customers’. Some people might be agreed with the statement. There are a lot of marketers that have innovative and creative thinking who usually ‘think outside the box’. They make a new product and service. An unusual product or service that launched by the marketers. They promote them and tell the market that they should buy this for goodness sake. Because they need it. So, people simply think that marketing might shapes or even create the need of the customers. But there is something that we have to consider. They are creative and innovative marketers who basically just like the other marketers. They collect data from the customers and the environment around them and then transform it into useful information. But, they who think outside the box can recognize the ‘new need’ of the customer. So they create product or service based on their recognition. Product or servic e that the customers might do not think to need it but in the end, the customers hold on that product or service. All we can say is that the marketers just recognize the ‘new need’ of the  customers, but not create them. Who creates them are the customers themselves. For example, when they need communication, they have cable telephone. But, the marketers recognize that the cable telephone might not appropriate for people nowadays. So now there are cell phones. Portable phones are now become a basic need. People can not live without communicate with the other people by cell phones. The marketers found the ‘new need’ just by analyzing the customers and the environment. But, the customers are basically creating them time after time. Marketing is about recognize the existing problem or even the new problem of the customers and tell the customers that they can solve it by their product or service. It is all about satisfying the customers’ need and want to gain value from them too.

Advantages and disadvantages of mobile phones Essay

The 21st century has seen the advent of amazing technological advances, one of which is of the mobile phone. Nowadays, a mobile phone consists of camera, MP3 player, alarm clock,†¦., or in another way, a mobile phone is a combination of more than 10 items of our daily lives. And so a mobile is a basic need and everybody has it. We can all see clearly the advantages of a mobile phone, but not everybody recognizes the down side of having one. As mentioned and well – acknowledged by everyone, convenience is an advantage of mobile phone. With a mobile phone, we are able to have instant contact with whomever we want, whenever we want, and also because it is a multi-functional device beside communication use, even more accurate for the new generations of smart phone. At present, a smart phone can access the internet using 3G or Wi-fi. Therefore, it is not just a phone, but a mini computer. Besides the obvious advantage, another comes to mind, and that is texting helping people to overcome shyness and awkwardness. Being late for a meeting, apologizing, telling loved things to someone,†¦ are all quite uncomfortable situations and speech can make things even worse. But text gets rid of those moments and replace it with a clean, logical and clear message. Furthermore, teenagers find mobile phones being an expression of their identity because they are beyond the control of parents. A mobile phone makes our lives quite easier, right? Not quite. As you can see, scientists have claimed that mobile phone produces a small amount of radiation waves, resulting to brain cancer, so long usage can be harmful to health. And in terms of health, there have been a great deal of traffic accidents caused by texting and calling while driving. So firstly a mobile phone can affect our health and probably our lives. Secondly, mobile phones can be great distraction at work and school. The internet, the games on smart phones, the endless number of applications, those are temptations, creating lack of concentration for people working and studying, which is an activity being definitely less exciting by comparison. In addition, mobile phones are sometimes disturbance in our lives due to the wrong-number phone calls, draft messages, prank calls,†¦. . These are very annoying and can lead to discomfort, especially if these are being made at night. Then there are environmental issues involved with mobile phone usages. According to a survey, people on average use their phone 11 to 18 months, a short period of time. And when those old phones become trash, and with the need of phones at  present, which is a lot, it can lead to pollution due to hardware of mobile phones being hard to dispose of. In conclusion, we use mobile phones on a daily basis for theirs obvious advantages, but we also need to be aware of the not so obvious or simply ignored disadvantages. On account of the mass demand of mobile phones, we need to know both sides of them in order to make the best out of a wonderful device.

Sample design for Blackberry

In sampling, an element is the object (or person) about which or from which the information is desired. In survey research, the element is usually the respondent. A population Is the total of all the elements that share some common set of characterlstlcs. Element: Objects that possess the information the researcher seeks and about which the researcher will make inferences. Population: The aggregate of all elements, sharing some common set of characteristics, that comprise the universe for the purpose of the marketing research roblem.The researcher can obtain Information about population parameters by taking either a census or a sample. Census: a complete enumaration of the elements of a population or study objects. Sample: A subgroup of the elements of the population selected for participation in the study. sample Large Time available Population size the characteristics Conditions Favoring the use of Factors census Budget Short Large Small small Long Small Variance in Large Cost of s ampling error High Cost of nonsampllng errors High Low Nature of measurement Nondestructive Attention to individual cases NoAdvantages of Sampling Sampling saves time and money Sampling saves labor. Destructive Yes A sample coverage permits a higher overall level of adequacy than a full enumeration. Complete census Is often unnecessary, wasteful. and the burden on the public. 1) Define the Population: Sampling design begins by specifying the target population, which should be defined in terms of elements, sampling units, extent and time frame. Population/Target population: This is any complete, or the theoretically specified aggregation of study elements. It is usually the ideal population or universe to which esearch results are to be generalized.Survey population: This is an operational definition of the target population; that is target population with explicit exclusions-for example the population accessible, excluding those outside the country. Element (similar to unit of analy sis): This is that unit about which information is collected and that provides the basis of analysis. In survey research, elements are people or certain types of people. Sampling unit: This is that element or set of elements considered for selection in some stage of sampling (same as the elements, in a simple single-stage sample).In a ulti-stage sample, the sampling unit could be blocks, households, and individuals within the households. Extent: This refers to geographical boundaries. Time frame: The time frame is the time period of interest. In our case; Population/ target population = Blackberry users Survey population = Blackberry users between the age of 18-24, which refers to university students regarding the demographical factors. Elements = Blackberry users who are university students Sampling Unit = Blackberry users in the Business Administration Faculty of Istanbul University. Extent = Business Administration Faculty of Istanbul UniversityTime Frame = 2 weeks between 4-15 N ovember Given the large size of the target population and limited time and money, it was clearly not TeaslDle to Intervlew tne entlre BlacKDerry users, tnat Is, to take a census. So a sample was taken, and a subgroup of the population was selected for participation in the research. Our sample/ subgroup can be seen above. 2) Determine the Sampling Frame: A sampling frame is a representation of the elements of the target population. To be specific, this is the actual list of sampling units from which the sample, or some stage of the sample, is selected.It is simply a list of the study population. Sampling frame of our case = List of the students in the Business Administration Faculty of Istanbul University. 3) Select a Sampling Technique: Selecting a sampling technique involves choosing nonprobability or probability sampling. Nonprobability sampling : relies on the personal Judgement of researcher, rather than chance in selecting sample elements. Convenience Sampling: as the name impl ies, involves obtaining a sample of elements based on the convenience of the researcher. The selection of sampling units is left primarily to the interviewer.Convenience sampling has the advantages of being both inexpensive and fast. Additionally, the sampling units tend to be accessible, easy to measure, and cooperative. Judgement Sampling: The researcher selects the sample based on Judgement. This is usually and extension of convenience sampling. For example, a researcher may decide to draw the entire sample from one â€Å"representative† city, even though the population includes all cities. When using this method, the researcher must be confident that the chosen sample is truly representative of the entire population.Quota Sampling: introduces two stages to the Judgemental sampling process. The first stage consists of developing control categories, or quotas, of population elements. Using Judgement to identify relevant categories such as age, sex, or race, the researcher e stimates the distribution of these characteristics in the target population. Once the quotas have been assigned, the second stage of the sampling process takes place. Elements are selected using a convenience of Judgement process. Considerable freedom exists in selecting the elements to be included in the sample.The only requirement is that the elements that are selected fit the control characteristics. Snowball sampling: is a special nonprobability method used when the desired sample characteristic is rare. It may be extremely difficult or cost prohibitive to locate respondents in these situations. Snowball sampling relies on referrals from initial subjects to generate additional subjects. While this technique can dramatically lower search costs, it comes at the expense of introducing bias because the technique itself reduces tne II population.Kellnooa tnat tne sample wlll represent a good ross section Trom tne Probability sampling: in this kind sampling elements are selected by ch ance, that is, randomly. The probability of selecting each potential sample from a population can be prespecified. Simple Random Sampling: is the purest form of probability sampling. Each member of the population has an equal and known chance of being selected. When there are very large populations, it is often difficult or impossible to identify every member of the population, so the pool of available subjects becomes biased. Systematic Random Sampling: is often used instead of random sampling.It is also alled an Nth name selection technique. After the required sample size has been calculated, every Nth record is selected from a list of population members. As long as the list does not contain any hidden order, this sampling method is as good as the random sampling method. Its only advantage over the random sampling technique is simplicity. Systematic sampling is frequently used to select a specified number of records from a computer file. Stratified Random Sampling: is commonly use d probability method that is superior to random sampling because it reduces sampling error.A stratum is a subset of the opulation that share at least one common characteristic. Examples of stratums might be males and females, or managers and non-managers. The researcher first identifies the relevant stratums and their actual representation in the population. Random sampling is then used to select a sufficient number of subjects from each stratum. â€Å"Sufficient† refers to a sample size large enough for us to be reasonably confident that the stratum represents the population. Stratified sampling is often used when one or more of the stratums in the population have a low incidence relative to the other stratums.Cluster Sampling: may be used when it is either impossible or impractical to compile an exhaustive list of the elements that make up the target population. Usually, however, the population elements are already grouped into subpopulations and lists of those subpopulatio ns already exist or can be created. For example, let's say the target population in a study was church members in the United States. There is no list of all church members in the country. The researcher could, however, create a list of churches in the United States, choose a sample of churches, and then obtain lists f members from those churches. ) Determine the Sample Size: The statistical approaches to determining sample size are based on confidence intervals. These approaches may involve the estimation of the mean or proportion. When estimating the mean, determination of sample size using a confidence interval approach requires a specification of precision level, confidence level, and population standard deviation. In the case of proportion, the precision level, confidence level, and an estimate of the population proportion must De speclTlea. I ne sample size aetermlnea statlstlcally represents ne Tlnal or net sample size that must be achieved.In order to achieve this final sampl e size, a much greater number of potential respondents have to be contacted to account for reduction in response due to incidence rates and completion rates. Non-response error arises when some of the potential respondents included in the sample did not respond. The primary causes of low response rates are refusals and not-at-homes. Refusal rates may be reduced by prior notification, motivating the respondents, incentives, proper questionnaire design and administration, and follow- up. The percentage of not-at-homes can be substantially reduced by callbacks.Adjustments for non-response can be made by subsampling non-respondents, replacement, substitution, subjective estimates, trend analysis, weighting, and imputation. The statistical estimation of sample size is even more complicated in international marketing research, as the population variance may differ from one country to the next. A preliminary estimation of population variance for the purpose of determining the sample size a lso has ethical ramifications. The Internet and computers can assist n determining the sample size and adjusting it to a count for expected incidence and completion rates.Sampling distribution: the distribution of the values of a sample statistic computed for each possible sample that could be drawn from the target population under a specified sampling plan. Statistical inference: the process of generalizing the sample results to the population results. Normal distribution: a basis for classical statistical inference that is bell shaped and symmetrical and appearance. Its measures of central tendency are all identical. Standard error: the standard deviation of the sampling distribution of the mean or proportion.Z values: the number of standard errors in point is away from the mean Incidence rate: the rate of occurrence of persons eligible to participate in a study expressed as a percentage Completion rate: the percentage of qualified respondents to complete the interview. It enables researchers to take into account anticipated refusals by people who qualify Substitution: a procedure that substitutes for nonrespondents other elements from the sampling frame that are expected to respond I rena analysis: a metnoa 0T a0Justlng Tor nonresponaents In wnlcn tne researcner tries to discern a trend between early and late respondents.This trend is projected to nonrespondents to estimate their characteristic of interest Weighting: statistical procedure that attempts to account for non-response by assigning differential weight to the data depending on the response rate Imputation: a method to adjust for non-response by assigning to characteristic of interest to the nonrespondents based on the similarity of the variables available for both nonrespondents and respondents.

How Does An Ems Work Environmental Sciences Essay

An tremendous sum of development in industrial sectors all over universe typically consequences in a turning figure of environmental jobs in proportion with the development. An Environmental Management System ( EMS ) is a model, which is designed to assist organisations in the direction, betterment and control of environmental public presentation. EMS is portion of direction system of an administration, where a clearly set out construction of an administration, duties of staff, processs, be aftering activities, resource allotment for execution, development and accomplishment of marks of environmental policy committednesss needs specifying. EMS is designed to understate environmental impact, to utilize resources more efficaciously, to do concern productiveness long-run, to better repute of an administration, to follow with environmental ordinances and statute laws, to better its fiscal place by cut downing fees for insurance, regulative license fees, to better staff morale, stakeholde rs ‘ relationships etc. The environmental impact varies between administrations, but by and large it is emanations, waste, energy use, ingestion and conveyance of stuffs. Impacts on wildlife and nature is a consequence of increasing clime alteration factors all over the universe, which is lead by contaminated land, air and H2O. In the 1970s and 1980s many administrations established their ain set of ordinances as a response of questions in environmental statute law. In the 1990s the International Organisation for Standardisation ( ISO ) introduced international criterions ISO14000 as portion of organisations ‘ direction systems. In 1992 the British Standard Institute published BS7750, which was the first national criterion for an environmental direction system. The intentional criterions help an administration or industry of any size to accomplish betterment of environmental public presentation by puting a specific environmental direction system. The work of an administration harmonizing to the criterions makes clear marks and aims of environmental policy, and identifies activities that significantly impact the environment. Cardinal elements of an EMS The Model of an EMS consists of four phases: Planning, Doing, Checking and Acting. Planning is the procedure of environmental injury designation by an administration, rating of environmental impact and the constitution of appropriate aims. It is necessary for an administration to reexamine its present stock list of environmental activities and place environmental facets, applicable environmental ordinances and instructions. Harmonizing to ISO14001, the environmental facet is an â€Å" component of an administration ‘s activities, merchandises or services, which can interact with the environment † ( ISO 2004 ) . Designation of environmental facets starts with the survey of activities, merchandises and services of an administration, which affects environment or which leads to environmental impact. All important facets should be considered to set up environmental aims for environmental policy and determine operational control and action in the manner to better environmental public presentation. Significant environmental facets should be stated in policy t o set up environmental aims and marks. Identification and direction of environmental facets leads to important environmental betterment. Environmental Policy is a statement, which is to declare liability to the execution and direction of EMS. Identified and assessed important impacts of an administration are the chief elements of an environmental policy, which is of import for set uping environmental marks and aims. It can be really utile to affect employees in this procedure, for illustration: to carry on brainstorming Sessionss, because there can be chances that can easy cut down the environmental impact. Aims and marks should be specific, accomplishable and mensurable. During and after execution of an EMS, alteration and rectification of the marks and aims should be portion of the monitoring and supervising procedure. Environmental policies should be apprehensible by every employee and employer of an administration to accomplish the marks and aims of the administration. Doing is the execution procedure of the plan to understate environmental impact and hazard of an administration. Harmonizing to ISO14001, the disposal of an administration should name a particular, trained direction representative to guarantee execution of the EMS. The EMS representative is responsible for monitoring, measuring, coverage of EMS public presentation to head direction and control activities that have important environmental impact. The EMS representative should besides collaborate with others to modify EMS as needed. All staff, whose activities can do important environmental impact should be trained on important environmental issues. Relevant staff should be trained on environmental policy, exigency, accomplishment of environmental marks, specific EMS functions and duties, the environmental impact of their occupation activities and effects in instance of relevant staff non following their relevant EMS duties. All processs and instructions to command important environmen tal impact and to place possible accidents, which could hold an impact on the environment must be clarified and documented. Activities of every employee have an impact on the environment and every employee should hold good thoughts associating to their experience about the betterment of environmental public presentation. That ‘s why it ‘s really of import to develop communicating in an administration by regular staff and safety meetings, suggestion boxes, newssheets etc. Effective communicating may assist an administration ‘s EMS execution to actuate people, better apprehension of environmental policies, functions and duties, importance of environmental public presentation betterment and placing possible for betterment. The cardinal function of disposal is to supply resources to employees, which are necessary for an EMS plan execution. Some people, such as clients, registrars, and authorities administrations can be interested to cognize the EMS design and execution of the administration. For these grounds, every administration should hold an EMS manual or EMS description papers. Documentation is one of the of import factors of effectual EMS direction. EMS paperss should be revised on a regular basis by responsible forces, who will do alterations as and when required. Certain operations and activities should be monitored and controlled to pull off important environmental impact and to guarantee that the processs implements to accomplish marks and aims. Operational control processs should be documented, particularly those where breach could take to important environmental impact. The possibility of accidents and incidents ever exist, even in malice of the best execution of an EMS theoretical account. Decrease of hurts, bar of environmental impact, protection of employees and understating losingss can be done by effectual preparation and readying to exigency state of affairss. The readying for exigency state of affairss can be provided by: capacity appraisal for incidents and accidents ; preventive steps on these accidents and incidents, related to environmental impact ; doing programs and processs to react to exigency state of affairss ; regular control and monitoring of the programs and processs and understating environmental impact related to these accidents and incidents. All EMS executions, processs and instructions should be continuously revised and updated. Checking is the assessment procedure, which assesses the effectivity of the plan and evaluates how execution of the plan meets plan aims. The assessment procedure is based on monitoring and measuring of environmental public presentation betterment of an administration. Internal audits are measuring whether the EMS of an administration meets the demands of ISO14001. Internal environmental hearers should be trained on appropriate issues. The effectivity of an EMS mostly depends on monitoring facets, which deals with disagreements of criterions. Monitoring and measurings helps an administration to measure environmental public presentation, conformity by the legal demands, place jobs, analyze root causes of jobs, happening ways to rectify jobs and bettering public presentation and effectivity. Identification and probe of jobs and their causes allows an administration to do disciplinary and preventive steps for the hereafter. Prevention of jobs is by and large far more cost-efficient than repairing them after the fact. Evidence of a on the job EMS is records. Record direction seems a bureaucratic procedure, but on occasion administrations need to supply EMS execution grounds to the 3rd parties ( e.g. clients, some authorities administrations and the populace ) . Administration of an administration decides what records should be kept, how and how long to maintain them. It ‘s really of import to stress needed EMS records to show execution of environmental public presentation betterment. Regular audits can be peculiarly valuable by supplying nonsubjective grounds that an EMS is implemented harmonizing to the demands. Regular audits critically evaluate the effectivity of EMS execution, consistently place and describe to disposal of administration on a deficiency of EMS execution. It provides a great chance to better activities on EMS execution, better environmental public presentation and do the system more cost-efficient. Acting is based on the appraisal procedure to take action for continual betterment of an EMS, which is performed by caput direction. The policy of EMS, objectives, marks and action programs must be reviewed annually by members of the Environmental Management Committee. Results of the EMS execution reappraisal should be reported to head direction, demonstrate to staff and happen out marks, aims, related actions and other elements of EMS that need to be changed. Management reappraisal is an of import cardinal component of an EMS for continual betterment, which besides provides a great chance for EMS execution to be effectual and low-cost. The procedure of a direction reappraisal should affect competent people, who have appropriate cognition and experience and who are decision-makers of the administration. All direction reappraisal meetings should be recorded and supply inside informations on what issues were discussed and what determinations and actions are selected for implementing.
