Dorian Gray Theme Essay - 690 Words

Josh Nitz April 16, 2012 Professor Anders Response #7 Dorian Gray Oscar Wilde’s fictional piece The Picture of Dorian Gray is a wonderful story that provides insight on the effect that sin has on the soul. In the beginning of the story Dorian is a kind hearted man, but by the end he becomes a cold blooded murderer who thinks only about himself. The ending is also very interesting in the sense that although Oscar Wilde escaped suspicion, revenge from James and those who could put his pursuit of pleasure in jeopardy, Dorian could not escape himself. This is the theme that really stuck with me. Dorian pursued pleasure with complete disregard for his soul or his conscience and in the end it led to his lack of pleasure and death.†¦show more content†¦Rather this strategic silence allows the author to move on with the story while still impacting the reader in the way he wants. In Hop Frog and Dorian Gray, the author’s vague description of wrong doing enables the reader to presume the worst from the antagonists and justi fy the antagonist’s grisly end. After Dorian murder’s Basil, Dorian begins to feel guilty and he swears he will start a new and wholesome life. Despite his efforts and his fortunate luck (James who was going to kill him died is a bizarre accident) Dorian cannot escape himself. The portrait of himself will always remind him of what he truly is inside. No matter what he does Dorian cannot escape the past or his wrong doings. This situation applies to most readers, as most people have gotten away with a sin. Although no one else knows about the wrong doing, the individual cannot escape the guilt or memory of what they have done. This is what happens to Dorian and the only way to escape his guilt is through suicide (unintentional). The Picture of Dorian Gray provides many good moral lessons that should be observed by anyone who reads the book. Morals that come to mind are â€Å"Beware your sin will find you out,† and selfishness will only bring you pain. Dorian Gra y tried to find individual pleasure, but pleasures are not found in the individual. Rather pleasure is found in love, God andShow MoreRelatedThe Dark Themes of The Picture of Dorian Gray and Dracula2593 Words   |  11 PagesThe concerns of Victorian England about the status of faith and manhood have left a deep mark in the literature of the period.

Censorship Censorship And Censorship Essay - 1513 Words

In the modern sense, political correctness has become a form of censorship. With protestors forcing students to find alternate routes to school or pushing the administration to cancel guest speakers in fear of triggering students, the modern-day university is no longer a place of free, critical, thinking, but a place of censorship. Political correctness (is used to describe language, policies, or measures that are intended primarily not to offend or disadvantage any group of people in society. In Juan William’s essay, ‘Defying the PC Police’, he discusses censorship, PC culture, and excessive political correctness. For William, excessive political correctness was the basis of his argument against the â€Å"PC police† and was defined as political correctness that goes beyond being respect to the point at which it becomes censorship. Competitively, the United States of America has very minimal censorship as compared to North Korea, Burma, Turkmenistan, Equato rial Guinea, Libya, Eritrea, Cuba, Uzbekistan, and Belarus, the nations that have the highest levels of censorship. As displayed in books such as 1984, Fahrenheit 451, The Giver and Go Ask Alice, censorship is a very controversial topic. Where the line between freedom of speech and the press are often questioned by politicians and parents alike, in the recent years, censorship has become an idea that is no longer protecting people, but an idea that is taking people’s freedom on a skewed claim of protection.

Pluralistic Approach to Moral Theory †Free Samples to Students

Question: Discuss about the Pluralistic Approach to Moral Theory. Answer: Introduction: Kants philosophy is basedon the aspect that the actions performed by the individuals are morally good. The main focus of Kantian Philosophy is that the individuals need to comply with the legal obligations for creating a good image within the workplace. In view of this perspective, discriminations should not be allowed in the workplace. This is because it results in the destruction of the workplace decorum (Harris, 2017). If the discriminations come from the employees, then they are violating the rules and regulations management. Moreover, this violation can be considered as deliberate, reflecting the deviation from the moral values. Attaching the case, engaging the employees into the workplace issues generates workplace diversity. Therefore, it is the duty of the managers to conduct group discussions for averting the instances of conflicts, discriminations and harassments in the workplace premises (Johnson, 2015). According to the Utilitarian view, the directions of the people should be based on exposing kind attitude to the people. This relates with the enhancement of social status through catering to the needs, demands and requirements of the clients. Based on this aspect, discriminations should not allowed in the workplace. This is because it does not ensure the wellbeing of the employees. The statements of Rachel expose the disinterest of the employees towards the recruitment and selection process. The adoption of new processes in the workplace issues and systems is good in terms of attracting the candidates (Vaughn, 2015). On the other hand, if this innovation brings biasness among the employees, it proves harmful for the productivity management. In this section, the centre of discussion would be the stakeholder theory under the utilitarian approach. The ethical decisions in the organizations are sometimes made under the influence of utilitarianism. The experts have debated that the companies or the service providers must have a proper relationship of trust among them. Only then the companies can take the competitive advantage properly (Waller, 2013)The case of the utilitarianism in the fighter workers has been really effective in this matter. If the companies can keep a better relationship with the stakeholders, this will help them to earn a better spot in the industry and have better financial outcomes. Trust is a very important, valuable and rare source that is very hard to achieve. As per the utilitarian sources, this will bring the best competitive advantage for the organizations (Hinman, 2012). The case of the fighter workers will have to be discussed in this section. The terrible consequences might take place because of the closing of the doors by the nations for all the outsiders (Waller, 2013).The immigration facilities have been misused and the most important stakeholder in this section is the government. Some of the major impacts or influences that can be caused in this context are the economic inefficiencies;the economic inequality is also one very gruesome factor in this issue (Reamer, 2013).The utilitarian approach in this matter is not at all acceptable since laws and rules of the country are violated. As the principle stakeholders, the government will have to adjust the immigration policies properly but not following the utilitarian approach. The political tyranny can increase because of taking the utilitarian approach indeed (Hinman, 2012). The case of the fighter workers might fall on the different people like the immigrants of one country, the native workers, and the national culture of the countries, labor markets of the concerned countries, capital flight, and entrepreneurship of the new businesses. There are other kinds of views as well. If the utilitarian approach is followed for the fighter workers, the security of the people will be in great distress (Reamer, 2013).It has been believed that the illegal immigration in the countries disturbs the natural peace of the country. Thus the people of the various countries are affected by illegal immigration and activity of fight workers who help to mitigate the problems. If the fight workers do not respond to the serious problems, the entire nation will be in a pool of trouble. Utilitarian view of the discriminations at the workplace One of the most important things to be addressed here is the discriminations in the workplace for the employees. The companies have to take some decisions for the employees that would make them happy (Hinman, 2012). The company has to identify the reasons for the general happiness of the employees. The pains and pleasures will have to be discussed in the various ways for the employees in the workplaces. If the employees are deprived of the self-development opportunities in the workplace, they will feel the pain management. The stresses that are caused during the sorrowful events at the workplace can be called as the reasons for the sorrow. If the employees get the proper job satisfaction this can cause them the pleasure and lead them to the general happiness (Hinman, 2012). It is very interesting to highlight on the facts of utility on the various aspects of utility. It means the human beings should have the ideas about the persons, actions and the institutions to get the happiness in the world order. The human motivation can be given from the aspects of the various sorts of the happiness among the human beings. Bentham and Mill both have the idea that the only aim of the human beings is to reach their happiness. Bentham has been very much hedonist in his approach to the human happiness (Trevino Nelson, 2016). The two sovereign components of the human nature are the pain and pleasure. Bentham has always insisted that happiness for the human beings is completely based on the pleasure of the human beings. The psychological hedonism can be attributed to the concepts of Bentham. Mill has treated this issue of hedonism to be axiomatic (Trevino Nelson, 2016). The psychological egoism and hedonism are the two most important elements of the entire scenario ab out the human happiness and motivation. The utilitarian view determines the fact about the utility of the agent and the happiness of the human beings. References Crane, A.

Children Being Exploited in Dickensian Times Essay Example For Students

Children Being Exploited in Dickensian Times Essay All through the ages children have been exploited. Children are easy prey they are innocent, feeble and trustworthy. Charles Dickens portrays children in a vivid and descriptive manner of hardship and death in Dickensian times.  Dickens felt strongly that industrial life in the cities was creating unfair class divisions which would lead in the end to violence. Other novels such as Great Expectations, Oliver Twist and Nicholas Nickelby, ( the novels I shall be exploring ) in particular show how keenly Dickens felt the wrongs done by adults to children. In the 1840s and 50s there was a fashion for looking at everything as if it was part of one logical system, where children were seen as imperfect adults and childhood itself a process called upbringing or schooling. Behind this attitude lay a philosophy called utilitarianism which stresses the practical usefulness of things. This meant that art and imagination, play and entertainment were not valued because they had no practical use. Dickens feared that all those things which made human beings diverse and interesting, free and creative, happy and warm hearted, were being driven out by the values of a factory system geared to only productivity and profit.  This leads me to the first novel I shall explore as the basis of how Dickens portrays the difficult lives of children in 19th Century England Nicholas Nickelby. I chose this novel as it shows how the abuse of children extended into the school system. The Principal of the school to which Nicholas attended was a man called Mr. Squeers. I believe that Mr. Squeers managed the school on the principle and philosophy that cost must be avoided. We see this with the condition of the school, bare windows, dirty rooms, long old rickety desks, inked and damaged in every possible way.  Dickens really comes into his own when he describes the condition of the children with such passion and graphic detail Pale, haggard, lank, bony, facial expressions of old men, deformities, stunted, meagre, stooping bodies, bleary-eyed, hare-lipped and every ugliness or distortion from their horrible endurance of cruelty. Mr. Squeers was teaching the children on what he called the practical mode of teaching, This means when a boy has learnt how to spell clean and winder, ( Mr. Squeers spelling of window), the boy goes and cleans the window! This is clearly exploiting children and as they are too weak or powerless they cannot object. Also, we see by Squeers ability to spell that children are receiving a bad education from this man. Dickens makes known, in no uncertain terms, his feelings on the matter of children and how the school system that Mr. Squeers runs is exploiting and cheating the children through Nicholas Nickelbys final paragraph. It uses such emotive language that you can clearly empathise with children. Led him ( Nicholas ) to be the aider and abettor of a system which filled him with honest disgust and indignation, he loathed himself and felt for the moment as though the mere consciousness of his present situation must, through all time come, prevent his raising his head in Society again.  The second novel I shall deal with is probably one of Dickens most famous novels, Oliver Twist. It is the tale of a young boy who is left in a workhouse as an orphan, without a friend in the world. He quickly finds himself in the middle of the seedy underworld of crime in London. The main ways in which children are exploited in this novel are by their being uneducated and innocent as Oliver has no idea of the outside world. The workhouse is where Oliver encounters Mr. Bumble, a cruel and evil task master who forces the children to work. Before this, Oliver was brought up unhappily in a foster home, run by a woman who cares more for the money she gets than for the children she looks after. When aged nine he was sent to live in the poorhouse. Dickens shows us how officials like Mr. Bumble had no feelings for children but only love for the power that they brought them. .u69862fef12a01199c337f042190a1ea9 , .u69862fef12a01199c337f042190a1ea9 .postImageUrl , .u69862fef12a01199c337f042190a1ea9 .centered-text-area { min-height: 80px; position: relative; } .u69862fef12a01199c337f042190a1ea9 , .u69862fef12a01199c337f042190a1ea9:hover , .u69862fef12a01199c337f042190a1ea9:visited , .u69862fef12a01199c337f042190a1ea9:active { border:0!important; } .u69862fef12a01199c337f042190a1ea9 .clearfix:after { content: ""; display: table; clear: both; } .u69862fef12a01199c337f042190a1ea9 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u69862fef12a01199c337f042190a1ea9:active , .u69862fef12a01199c337f042190a1ea9:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u69862fef12a01199c337f042190a1ea9 .centered-text-area { width: 100%; position: relative ; } .u69862fef12a01199c337f042190a1ea9 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u69862fef12a01199c337f042190a1ea9 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u69862fef12a01199c337f042190a1ea9 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u69862fef12a01199c337f042190a1ea9:hover .ctaButton { background-color: #34495E!important; } .u69862fef12a01199c337f042190a1ea9 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u69862fef12a01199c337f042190a1ea9 .u69862fef12a01199c337f042190a1ea9-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u69862fef12a01199c337f042190a1ea9:after { content: ""; display: block; clear: both; } READ: Literary Techniques Poetry Analysis EssayI think when Mr. Bumble goes and collects Oliver to bring him to the poorhouse, he says, Will you go along with me, Oliver?  Oliver replies, Will she go with me ? indicating to the woman who looked after him. He was hoping she would not as he disliked her and he wanted to go to the workhouse, unknowing what this entailed.  Dickens yet again shows his true cynical feelings on exploitation of the poor and helpless by using great descriptions to show how underfed the boys were. The bowls never wanted washing, as the boys polished them with their spoons till they shone again. They looked at the copper with such eager eyes as if t hey could have devoured the very bricks of which it was composed. This gives us a good idea of how children were treated. The novel gives us no real indication of how hard Oliver worked or what his work involved except when it said, So, youll begin to pick oakum tomorrow morning at six oclock. Apart from being an early start, from investigation I found out that pick oakum meant pull old rope apart for recycling a dirty, laborious job given usually to convicts.  Oliver runs away to London and is befriended by The Artful Dodger, who sees Olivers naivety and brings him to a villainous old man named Fagin.   I know a spectable old gentleman as lives in London, wotll give you lodgings for nothink, and never ask for the change. Oliver is yet again taken advantage of as he has never met this kind of friendship where someone such as the Dodger and Fagin are friends with Oliver because they can use him to further their own gains. Oliver is oblivious to the fact that what Fagin and his gang are doing is wrong. He is laughed at but doesnt see it, like when he makes innocent comments about wanting to learn the trade of making hankerchiefs.

applications of technology essays A quote I heard many times when I was in high school and which I now know traces back to Sir Francis Bacon, one of our earliest scientist or philosophers as they were then called, is the statement "Knowledge Is Power." Today, I believe that the fuller, more correct statement is to say, "the application of knowledge is power." The study of science, and technology subjects will broader our opportunities in life. As we continue to advance to the 21st century- now lesser than 30 days away-we are well aware that technology is possibly the hottest industrial commodity around the world today. In the years ahead, it will be an increasingly critical factor in determining the success or failure of businesses. It is the fuel many of us are looking at to help us win this race to the 21st century. To do that, we should make technology matter. In this paper I am going to share my technology forecasts. I try to focus on my new forecasts a decade into the future - the first decade of the 21st century, because that is how far most businesses need to be looking ahead. There has never been a neutral or value-free, technology. All technologies are power. They evoke economic and social consequences in direct proportion to their dislocation of the existing economy and its institutions. I believe that technologies such as: biotechnology and genetic engineering, intelligent materials, the miniaturization of electronics, and smart manufacturing systems, and controls, will be the hottest technologies in the next decade. I am going to put together a list of what I think as the top ten innovative products that will result from those technologies. Number one on the list is something we call genetic. There are pharmaceutical products that will come from the massive genetic research going on around the world today. In ten years, we will have new ways to treat many of our ills - from allergies to ADIS. We may see the discovery of new methods of treatment...

â€Å"Come on Rico, just get in the car and let’s get out of here,† exclaimed Jack, Rico’s best friend. Rico stands next to the passenger door, with his hand on the handle, but is frozen. Racing through his mind are both reasons for going with his friends and reasons for staying home. He knows his friends have been drinking heavily, but he does not want to feel left out. On the other hand, Rico has strong morals and knows what may happen if he gets in the car.

Societal Functions of Religion According to Emile Durkheim and the Essay

Societal Functions of Religion According to Emile Durkheim and the Decline of Religion in the United States - Essay Example The wealth that the U.S. has enjoyed over the past decades, the freedom of expression entrenched in the U.S. Constitution, and the acceptance of other religions into the American society have diluted the place of Christianity in the U.S. The decline of Christianity in the U.S. at the expense of other religions and secularism risks to threaten the American society if it fails to provide a compromise to people from other faiths or sharing other beliefs. Such risk exists because there could be clashes between people from different communities/ faiths (e.g. Northern Ireland). The situation, however, is not alarming because religion has been replaced in the U.S. by education and to some extent a sense of patriotism. To revert back to Emile Durkheim's theory of religion, patriotism, education, the "American dream", Hollywood, etc. now ensure some form of social cohesion in the U.S. through the sharing of common values. With regard to social control, the law enforcement system and the judic iary system are now recognized as legitimate institutions to deal with conflicts. In this modern U.S. society, religion has been relegated to the personal realm and people living in the U.S. now enjoy the freedom to choose the religion that will answer their existential thirst.

Literature Review on Culture Shock and Poor Adjustment Essay

Literature Review on Culture Shock and Poor Adjustment - Essay Example The term culture shock was first coined by Kalvero Oberg (1960) in order to describe anxiety which resulted from the situation of not knowing or getting familiar with the new culture. The recent literature tends to recognise that culture shock can be applied to any new situation with regards to job, relation and also in relation to adjustment and new identity (Pedersen, 1995, p.1). Oberg has mentioned six aspects of culture shock such as strain which might occur in order to make some psychological adjustments; a feeling of loss or deprivation with relation to factors such as profession, friends, possession and status; by being rejected; confusion in knowing exactly the role, the expectation from the role, self identity, feelings and value; Anxiety, surprise, indication and disgust after knowing about the culture difference and a feeling of failure for not being able to cope with the new environment. Most of the researchers have tried and attempted to extend and improve believe of Obe rg that culture shock is just a normal process of adjusting cultural stress. According to Anderson (1994), culture shock is a symptom of frustration reaction (Selmer, 1999, p. 517). Cultural shock, over the last decade has received increased attention where Jack London in one of his stories titled â€Å"In a Far Country† had stressed to the fact that visitors who visit another culture needs to be prepared to adopt new customs and leave behind old thoughts and ideas. He suggested that sojourners who temporary reside in another country should be able to seek pleasure in the given condition because of the fact that those who were unable to fit into the new culture tends to return home or die due o physical and psychological ailments. Culture shock is a costly affair for a firm because it leads to premature return of business people who are sent overseas. According to some of the research employees sent to foreign did not fail because of lack of technical skills but inability to adapt the other culture. An estimate of early return showed a range of 45% to 85% employees who returned from overseas. However some companies have experimented with short term stays like two three months and determine the potential of the employee to tolerate other culture so that at a later stage they get prepared for longer stay. Short trips tend to be cost effective as it reduces the burden of moving the family also. Brislin (1981) had identified three strategies which can be used to cope up with the new culture in terms of short visits, Unacceptance of host culture: The travellers do not make any effort to understand and learn the new culture and behaves as they are in home culture Substitution: The travellers tend to learn appropriate behaviour and response from the host culture and substitute them with the one which they use it in the known environment. Addition: The people visiting overseas add the behaviour of the host country in the present of nationals but also maintain t he same behaviour when they are confronted with the same culture. Synthesis: this is a strategy which tends to combine the elements of two cultures such as dress on US and Philippines. Resynthesis: this is

Compare and Contrast Army Ground Fleet Maintenance with Civilian Research Paper

Compare and Contrast Army Ground Fleet Maintenance with Civilian Ground Fleet Maintenance - Research Paper Example Civilian institutions conduct business with the aim of profit making while US Army is a non-profit generating government function. This causes both similarities and differences in terms of activities performed in their respective fleet management systems. Below is a comparison and contrast between the two institutions. There is a couple of differences between the U.S. Army Ground Fleet Maintenance activities and the Civilian Ground Fleet Maintenance activities of organizations such as Coca Cola, Pepsi, etc. Some of these differences stem from a legal perspective while others stem from operation activities undertaken in the military bases. Some of the notable differences include; the military outsources its fleet management function to the industry including even tactical vehicles used by the military. For instance, the military in made a decision to outsource its fleet of M109 vehicles family (Paladin) that encompasses the M109 self-propelled howitzer & the M992 field vehicles supplying artillery ammunition under the fleet management program (NDIA Staff, 1999). Further, under the same program, the manager is responsible all resources of technical nature ranging from field maintenance to training hence making him responsible for the entire spare parts modernization, while soldiers control the daily maintenance activities. On the other hand, in the Civilian Ground Fleet Maintenance activities, outsourcing of the fleet management program is restricted to the organizations’ departments mandated to control and manage the company fleets, especially the transport department. For instance, unlike in the military where the function of outsourcing of maintenance services is a policy, in Civilian organization outsourcing of the maintenance activities is done in-house by the organizations workers e.g. in the case of Coca-Cola. Therefore, unlike in the military, Ground Fleet Maintenance activities are accomplished

Research into Cancer Stem Cells

Research into Cancer Stem Cells Cancers are composed of a heterogeneous mix of cells with varying differentiation, proliferation and tumourigenic properties. In vivo studies have demonstrated that within a cancer population, only percentage of cells are able to initiate tumour development [1]. It is widely believed that the heterogeneous groups of cells include a small population of cancer cells with stem cell properties: the cancer stem cell (CSC). These cells have the capacity to self-renew and differentiate asymmetrically and give rise to bulk populations of nontumourigenic cancer cells. Current cancer treatments may eradicate the tumour bulk but spare the populations of stem cells which are able to restore tumour tissue causing recurrence of the cancer. This may explain why initial tumour regression does not necessarily translate to improved patient survival in many clinical trials. Identification and characterisation of these stem cells may offer means of targeting cancer at its root. Cancer Stem Cell Definition The AACr workshop in 2006 defined a cancer stem cell as: A cell within a tumour that possesses the capacity to self-renew and to cause the heterogeneous lineages of cancer cells that comprise the tumour. Cancer stem cells can thus only be defined experimentally by their ability to recapitulate the generation of a continuously growing tumour.[2] Therefore the stem cell definition requires that cell possess 2 fundamental properties. Self renewal, the process whereby at least one daughter cell of a dividing stem cell retains stem cell properties Potency, the ability of cells to differentiate into diverse cells that comprise the tumour. [3]. It was agreed that defined CSCs may not necessarily derive from normal tissue stem cells, indeed one important and unanswered question is whether tumours derive from organ stem cells that retain self renewal properties or whether tumour stem cells are proliferative progenitors that acquire self-renewal capacity [2]. Normal Tissue Heterogeneity The continuous replacement of differentiated, functional cells by proliferation of more primitive cells in human tissue is a normal homeostatic process. Organs are composed of collections of differentiated cells that perform discrete functions [4]. The total cell population is regarded as constituting a cell division hierarchy [5]. The stem cell is central in the renewal hierarchy and has two functions within this model. It can act as the initiating cell in a cell division and differentiation process, producing a large family of differentiated descendants, a process known clonal expansion. Another function is for the cells to undergo division to produce two stem cell daughters identical to the initial stem cell and to replace the stem cells used in clonal expansion. This process is called self-renewal [6] and is shown diagrammatically in Figure 1. As cells move down the hierarchy they acquire the differentiated features associated with tissue function and the proportion of differenti ated cells increases. In this way the stem cell has the ability to maintain organ life [4]. This concept predicts the existence of three categories of cell within the population: Proliferating, self renewing stem cells; Proliferating non-renewing transitional cells (transit amplifying); Non-proliferating, differentiated end cells. Following division the stem cell can give rise to a transit amplifying cell that will undergo further rapid proliferation to produce offspring which expand the populations of cells arising from the initial division and progressively commit irreversibly to differentiation along one or several lineages[4]. An important feature of a stem cell is their ability to undergo asymmetric cell division giving rise to a progenitor cell and to a new stem cell. Somatic SCs reside in confined tissue compartments referred to as the niche. Here the microenvironment suppresses SC proliferation, resulting in a quiescent SC population. This population maybe triggered to proli ferate and differentiate in response to injury (Ghotra, 2009). Seven common and distinguishing features of stem cells have been described [4]: Stem cells comprise a small subpopulation of a given tissue. Stem cells are ultra-structurally unspecialized, with a large nuclear-to-cytoplasmic ratio and few organelles Stem cells can be pluripotent Stem cells are slow cycling but may be induced to proliferate more rapidly in response to certain stimuli Stem cells have a proliferatve reserve that exceeds an individuals lifetime An intermendiate group of transit amplifying cells exists The microenvironment plays a critical role in the homeostasis of the stem cell and the differentiation of its progeny. The stem cell is capable of division and clonal expansion. As cells differentiate they lose their proliferative potential. The stem cell can self renewal or divide to produce proliferative transitional cells. Tumour Heterogeneity It has been recognised for many years that tumours exhibit morphologic heterogeneity but they are also functionally heterogeneous in terms of cell proliferation and tumour forming capacity based on transplantation assays [7]. Heterogeneity within tumours is seen within individual tumours in terms of morphology, cell surface markers, cell proliferation kinetics and response to therapy. In vitro and in vivo observations suggest that most cancer cells do not proliferate and that loss of capacity to divide is a feature of the tumour. Only a small proportion of cells have the ability to form tumours in vivo, referred to as tumourgenicity. The cancer stem cell theory posits that neoplasms, like physiological tissue can be hierarchically organised, and that CSCs at the apex of this of this cellular hierarchy and seem to comprise of only a subpopulation of tumour cells are essential for its initiation [8, 9]. Two models have been proposed to explain tumours heterogeneity Stochastic and Hiera rchy, summarised in Figure 2. Both models account for the existence of a cell with stem cell properties, but only the hierarchy model predicts the existence of a stem cell at the top of a hierarchy, which the potential to produce all other cell types within the tumour. Stochastic Model The stochastic model predicts that a tumour is biologically homogeneous and the behaviour of the cancer cells is influenced by intrinsic (eg signalling pathways, levels of transcription factors) or extrinsic factors (eg host factors, immune response, and microenvironment). It is suggested that the randomness and unpredictability of these factors result in heterogeneity in many aspects of marker expression and tumours initiation capacity [10]. A key requirement of the stochastic model is that all cells are equally sensitive to such influences and that the cells can revert from one state to another. For this model to be functional all tumour cells are not permanently affected and all have equal capacity to be induced to one state or another and the changes upon the cell are not permanent [11]. A growth fraction of Hierarchy Model The second model is the hierarchy model which predicts that the tumour is a caricature of normal tissue development and a hierarchy where the stem cell is at the tops is maintained (Pierce) [7]. The cancer stem cell maintains itself and its clones by self-renewal. The cells also mature to produce differentiated offspring which form the bulk of the tumour and lack stem cell properties. As in normal tissue only a small percentage of the tumour population maintain the capacity for long term proliferation while most cells proceed forward down the differentiation pathway resulting in aberrant terminal differentiation [4]. Due to differences in characteristics, stem cells can be selected and enriched for. Variations in tumour growth rates may be due the effects of normal homeostatic mechanisms that regulate stem cells and transit amplifying cell reproduction or alterations of the stem cell niche microenvironment [4]. Much of the evidence for this comes from clonogenic and tumourgenic assay s, which will be discussed further. Hierarchy model contains cells that are composed of biologically distinct cells including cancer stem cells which are all have different functional properties. The stochastic model predicts that all cells are equal the cell heterogeneity is due to intrinsic and extrinsic influences upon the cells which result in heterogeneity of cell function. Experimental Evidence Early Work The first evidence for the existence of cancer stem cells came from functional cell proliferation studies in the1940s 1960s. Radiolabelling cells and autoradiography enabled measurements into the proliferation, lifespan and hierarchical relationships in normal and neoplastic tissues [10, 12]. From these studies came the proposal that tumours are caricatures of normal development including the existence of stem cells [7]. Much early work was on the cancer of the haematopoietic system. In the 1970s Clarkson and other groups carried out pioneering studies that established cancers exhibited functional heterogeneity [10, 13]. These include cytokinetic studies carried out in cell lines, murine models of the acute leukaemias and in vivo examination of leukaemia blast proliferation kinetics in human AML and ALL patients. The data showed that the majority of leukemic blasts were post mitotic and needed to be continuously replenished from a relatively small proliferative fraction. Only a smal l number of leukemic blast cells were cycling in vivo and of these two proliferative fractions were observed: a larger, fast cycling subset with a 24 hour cell cycle time and a smaller, slow cycling, with a dormancy of weeks to months. From this data it was suggested that the slow cycling fraction was generating the fast cycling fraction thought to be the leukemic stem cell population because they had similar kinetic properties to those observed for normal haematopoietic stem cells. This was a clear suggestion that tumours exhibit functional heterogeneity in terms of proliferative potential. Following the identification of these slow cycling cells it was predicted the inability to kill the leukaemic stem cells (LSCs) was the cause of relapse and failure of chemotherapeutic therapies. Whilst combining treatment with in vivo cytokinetic studies, investigators observed that LSCs respond to the depletion of the of the leukemic cell mass by go into cycle after chemotherapy. It was sugges ted the way to eliminate dormant LSCs was to find the window when they are cycling. Identifying and assaying the potential LSCs was a major stumbling block and characterising them was impossible. This was when attention focused on the clonogenic assay was adapted by several groups to assay AML which identified phenotype of AML cultures in vitro with differing proliferative potential, providing the further proof for hierarchy in AML [14-16]. Clonogenicity Definition of a clone A clone is an operationally defined as a group of cells derived from a single ancestor cell. Clonogenicity is the ability of a given cell population, when plated as single cells, to produce one or more clones. This can be measured by the clonogenic assay which can quantify the proportion of colony forming cells, as a percentage of plated population, referred to as colony forming efficiency (CFE). It has been suggested that colony-forming cells possess two fundamental properties of progenitor cells: the ability to give rise to differentiated descendents and the capacity for self-perpetuation [17]. Therefore the ability to measure the capacity of cells to form clones is a useful tool in the study of the cancer stem cell concept. Quantitative measurement of clonogenicity Development of the clonogenic assay. Puck and Marcus The first clonogenic assay In 1956 Puck and Marcus published a paper describing a cell culture technique for assessment of colony forming ability of single mammalian cells [18]. Plated in culture dishes with a suitable medium human cervical carcinoma cells (HeLa) were supplemented with a large number of irradiated feeder cells and the number of colonies formed was counted. Their technique was a simple rapid method for growing single mammalian cells into macroscopic colonies with a colony forming efficiency of 80 100% . The authors developed this assay further to enable quantification of the effects of high energy radiation on cell populations in vitro [18-20]. They plated HeLa cells and measured their response to x-rays, producing the first in vitro radiation cell survival curve [21]. This assay has since been used for a wide variety of studies with many cell types using improved culture conditions, and for the testing of many potential chemotherapeutic agents. Till and McCulloch Following the work of Puck and Marcus, Till and McCulloch generated the first in vivo survival curves [22, 23]. They showed that when mouse bone marrow cells were injected into recipient mice that had been given total body irradiation to suppress endogenous haematopoiesis, visible colonies developed in the spleens that derived from cells in the graft. This work demonstrated that the cells injected into the mice were capable of self-renewal and it was speculated that these cells were stem cells. The evidence for this conclusion was that the curve from the number of marrow cells transplanted proportional to the number of colonies developed within the spleen. In addition, the radiation survival curve of cells that form colonies closely resembled survival curves developed by Puck and Marcus for in vitro cells [21]. This, however, was only indirect evidence and did not prove that the colonies originated from single cells, so the group carried out further experiments to determine the singl e cell origin on the colonies within the spleens [24]. Heavily irradiated bone marrow was transplanted into heavily irradiated recipient mice. The idea was that some cells containing genetic abnormalities caused by irradiation in the donor bone marrow cells would retain the ability to proliferate and produce clones containing this abnormality [24]. This worked to some extent, with a small number of colonies containing cells which all showed the same chromosome abnormality within that colony. It was hypothesised that if the capacity to form colonies is to be considered as a criterion to identify stem cells, then cells must lose this capacity upon undergoing differentiation. This hypothesis was tested by applying hypoxia as a differentiating pressure to mouse bone marrow, which resulted in a reduction in colony formation in the spleens of hypoxic mice [17]. They described how the number of colonies form in the spleens of mice in hypoxic conditions is reduced. This was thought to be du e to hypoxia stimulating erythropoiesis which stimulates erythropoietin, indicating that erythropoietin reducing colony forming production in the spleen. This data suggested that an increased demand for differentiated cells reduces the number of stem cells, resulting in the reduction of colony forming ability. Later Developments Since its development, the in vitro clonogenic assay has become a valuable tool in the study of cell growth and differentiation. [25]. Several adaptations to the original method have been made including immobilising cells in a top layer of 0.3% agar to avoid formation of tumor cell aggregates by random movement which might be confused with colony growth [26]. Agar has also been replaced by some groups with agarose, which is easier to handle (Laboise 1981) or methylcellulose which allows better recovery of the colony for replating. Others have simplified the culture medium and omitted the need for feeder cells. The exact protocol depends largely on cell type, but the basic system remains the same. The development of a protocol for secondary plating efficiency has proved a useful tool for the measurement of self-renewal and has the advantage of being able to identify cells that are able to undergo a large number of cell divisions [26]. This involves selecting specific colonies to deter mine their proliferative potential over a number of passages. Clonogenicity and Cell Renewal Hierarchy Clonogenic assays have been used to identify and morphologically characterise the three cell types above. Barrandon and Greens [27] work identified the clonal types of keratinocytes and linked this to their capacity for multiplication. They defined colonies as Holoclone, Meroclone or Paraclone. The Holoclone was described as a colony with a larger smooth nearly circular perimeter containing many small cells, which it has been suggested that these cells represent the proliferating self renewing stem cells. Paraclones were described as differentiated end cells which are more elongated and flattened in appearance, however paraclones can divide quite rapidly therefore classification of clonal type cannot be deduced form the study of growth rates alone or morphology alone. Meroclones were described as a combination of holoclones and paraclones. Relating morphology and colony size to clonogenicity can be used to further identify potential stem cells within the clonogenic assay and give mor e detail to the fate of their descendents. The differences in growth unit size may reflect several properties including different proliferative capacities and clonogenic cell kinetics. However, clonogenicity in vitro alone, does not define a stem cell, and other subpopulations, such as transit amplifying cells may also be able to produce a colony size of 32 or more cells. Although ability of a cell to form a colony implies substantial proliferative capacity, this does not unambiguously identify a stem cell [28]. Tumor Cell Heterogeneity and Hierarchy Certain characteristics have emerged from clonogenic studies on cells derived from human tumors. It was noticed that a few cells in each tumor were able to give rise to colonies in culture, whilst some colonies contained transit amplyifing cells undergoing a limited number of terminal divisions. Other cells (usually the majority) were non-proliferating stem cells. Looking at CFE and colony size of human tumors and replating experiments has demonstrated the heterogeneity of a wide range of tumor types including neoplastic human urothelium [29], melanoma [30, 31] and squamous carcinoma [32]. This supports the idea that cells within solid tumors consist of cellular hierarchies, which will be discussed further. The cancer stem cell model accounts for heterogeneity within a primary cancer by proposing that each cancer consists of a small population of cancer stem cells and a much larger population of cells which have lost their self-renewal capacity [5]. The clonogenic assay has been used explore this cellular heterogeneity present in human tumors, lending support to the stem cell model of tumor growth. Multiple myeloma has served as a valuable model in early clonogenic assay development. This was studied by Hamburger and Salmon in 1977 [33], who created an essentially selective system which restrict proliferation to cells capable of anchorage independent growth, thought to be a characteristic of stem cells [34]. They described an in vitro bioassay for human myeloma colony-forming units in culture which was applied to the study of patients with multiple myeloma and related monoclonal bone marrow derived B cell neoplasm. Bone marrow samples from patients with multiple myeloma and normal volun teers were cultured in the presence of an agar feeder layer prepared by either human type O+ washed erythrocytes or adherent spleen cells of BALB/c mice. They found a linear relationship between colony formation and the number of nucleated bone marrow cells plated. Multiple myeloma patients exhibited much higher numbers of colonies formed compared to normal volunteers. It was shown that the number of colonies was proportional to the number of colonies plated, suggesting that colonies were derived from single myeloma stem cells. This was the development of the human tumor stem cells assay. The Human Tumor Stem Cell Assay clonogenicity and cancer stem cells The ability to grow human solid tumors in two-layer soft agar culture was developed for the clinical application of testing in vitro tumor sensitivity or resistance to chemotherapeutic agents. It is a possible means by which anticancer drugs can be selected for activity against tumor cells from a patient [35] as a way of tailoring chemotherapeutic regimes to individual patients and of testing new cytostatic agents [36]. The assay assesses treatment effects of stem cells by a testing their ability to reproduce and form a colonies of cells. Using semi-solid agar with enriched medium supports colony growth from cell suspensions from a variety of human tumors. A semi-solid medium suppresses the growth of most normal cells and there is evidence of the malignant nature of these colonies [33] . An important consideration is the relationship between the response of clonogenic cells to drugs in vitro and the response of the tumor to the same drug in the patient [10]. The stem cell model of human cancer suggests that cure or duration of remission after clinical treatment should correlate only with killing of stem cells. Assessment of treatment effects on an unselected cell population (eg on the basis or morphological criteria) is therefore likely to be misleading since the effects on a small population of stem cells will be masked by those on the large population of stem cells. Human tumors of a single histological type appear to have a pattern of response in vitro that is similar to their clinical behaviour. Within a histological type, tumours are heterogeneous in response both in vitro and in vivo. Studies directly comparing the response in vitro with the subsequent clinical response have shown important correlations. The proportion of human tumors that grow with a plating efficiency sufficient for assessment of drug activity (à ¢Ã¢â‚¬ °Ã‚ ¥30 colonies per 500,000 cells plated is frequently less that 50%. Usually only a proportion of these tumors will manifest in vitro sensitivity [37]. There have been a wide range of predictive value positives reported for the human clonogenic tumour cell assay when applied to a patient population with an expected clinical response rate of 15-49% [38]. This value could be misleading and in practice may only be workable for cytotoxicity testing for only one third of specimens tested. The limitation exits that not all sam ples will produce clones in vitro so those that do may exhibit a treatment bias [35]. Other problems with the use and interpretation of human tumor clonogenic assays include low plating efficiency and small proportion of tumors available for testing; difficulty in preparing single cell suspensions, production of only small quantities of data, and problems defining drug sensitivity and response criteria [35]. Factors influencing size of sub-populations It has been proposed that as in normal cell populations, human tumor cell populations are also heterogeneous and comprise stem cells, non-stem transitional cells with limited proliferative capacity and end cells [6]. MacKillop suggested that four factors may influence the relative size of these subpopulations: The probability of self-renewal (Psr) of stem cells (producing two daughter stem cells). The distribution of cells within the system can be treated mathematically by assuming probability functions. The potential of the transitional cells for further cell division, as defined by clonal expansion number (n=number of generations between the first generation non-stem cells and the end cells.) The relative effect of cell loss on each subpopulation (Stem cells, transit amplifying, end cells) as described by cell loss factors (ÃŽÂ ¦s, ÃŽÂ ¦t ÃŽÂ ¦ ec). The number of generations of cell proliferation following initiation of the tumor cell population for individual stem cell. Stem cell division in normal tissue must provide a supply of differentiated functional cells to compensate for physiological losses and at the same time maintain a constant stem cell population. A probability of self-renewal in which two stem cells daughters Psr =0.5, would yield a steady state [28]. If no cell loss occurs, it has been modelled that the number of stem cells will increase exponentially with Psr > 0.5 [6]. For the simplest case in which all non-stem cells are end cells (n=0) the proportion of stem cells increases linearly with increasing Psr. and the proportion of stem cells in a tumor decreases as the extent of multiplication of the transitional cell compartment. This results in the stem cell being the less common cell type numerically than transit amplifying and differentiated end cells. These scenarios are affected by cell loss which may occur through necrosis, migration or differentiation, of which only differentiation is selective of cell type. A selective loss th rough differentiation increases the population of stem cells. The modelling of tumor cell growth has implications for the use of clonogenic assays as predictors of the stem cell fraction on human tumors, especially in regards to cut-off points in terms of colony size and determining which cells represent the stem cell fraction [6]. Between studies there are differences between how colonies are scored morphologically and numerically and how long cells are allowed to grow [31] and considering this evidence may be an important issue when comparing data between different studies. Clonogenicity in cell lines and stem cells in cell lines Clonogenicity has recently been used to identify stem cell properties of cells in long term culture cancer cell lines. The colony forming efficiency and secondary plating efficiency of carcinoma derived cell lines including head and neck squamous, breast [39] and prostate [39-42] were investigated and considered to contain potential stem cells. These studies show that cell lines show clear differences between clonal types (holoclone, meroclone, paraclone) and have similar properties in this respect to normal epithelial cells [39]. The proportions of clonal types between the carcinoma cell lines vary greatly. DU145 colonies were evenly spread in number between the clonal types, whereas PC3 cells produced mainly meroclones and LNCaP cells produced mainly paraclones [41], all based on colony morphology. These studies have also looked at the relationship between potential cancer stem cell markers and clonogenicity. CD133 enriched DU145 cells were assayed for clonogenicity, but no difference was found between the positive and negative cells [41], but when isolated CD44+ integrin ÃŽÂ ±2ÃŽÂ ²1+ CD133+ sorted cells were compared against CD44+ integrin ÃŽÂ ±2ÃŽÂ ²1low CD133low a higher CFE was observed in conjunction with a marked difference in morphology to CD44+ integrin ÃŽÂ ±2ÃŽÂ ²1-/low CD133- in DU145 MACS sorted cells [40]. Immunocytochemistry demonstrated that different clonal types showed varying levels of expression of CD44, ÃŽÂ ±2ÃŽÂ ²1 integrin and ÃŽÂ ²-catenin in PC-3 [42] and DU145 clones [39]. There is further evidence to suggest the presence of cells with stem cell behaviour such as dye-exclusion and higher clonogenicity, in several human epithelial cell lines [39, 43-45], which further supports the idea that cell lines contain stem cells. The ad vantage of cancer cell lines that contain cells displaying stem cell characteristics would facilitate the study of molecular pathways and the properties that define the cancer stem cells in vitro. Recent Developments Much progress has been made in the modelling of the leukemic diseases, where the level of heterogeneity was first and most thoroughly explored. Human cells fulfilling the properties expected of drug resistant cancer stem cells were initially isolated from blood cancers [2]. Improvements in the genetics of recipient mice have led to the definition SCID-repopulating cell (SRC). Many improvements to the NOD/SCID murine model continue to be made by using recipient mice that are engineered to be deficient in natural killer (NK) and macrophage activity; part of that innate immune system. It has been demonstrated that a small subpopulation of acute myeloid leukaemia cells with an immature immunophenotype possess the ability colonise immune deficient NOD/SCID mice to give rise to more differentiated leukaemia cells and to recapitulate the heterogeneous phenotype of the bulk tumour [46]. The phenotypically more mature cells failed to engraft in mice, suggesting the presence of an identifiable tumour cell hierarchy. These cells are referred to as tumour initiating cells. Cancer Stem Cell Identification CSCs have been defined on the basis of their ability to seed tumours in animal hosts, to self renew and to spawn differentiated progeny (non-CSCs)[47]. Pioneering work in this area originated from studies on leukaemia stem cells and later included demonstrations of CSCs in solid tumours, particularly breast and brain cancers. However, work in solid tumours has proved challenging. The frequency of CSCs in solid tumours is highly variable [48]. Difficulties with tumour CSC identification Evidence for the existence of cancer stem cells in solid tumours has been more difficult than in the haematopoietic system to obtain for several reasons: 1) The cells within the tumour are less accessible. Tissue has to undergo mechanical or enzymatic digestion to obtain a single cell suspension which can be analysed. 2) There is a lack of functional assays suitable for detecting and quantifying normal stem cells from many organs. 3) Only a few cell surface markers have been identified and characterised. Of these there is no one marker which is specific for a stem cell or cancer stem cells and for selection they often have to be used in combination. Cancer Stem Cell Markers Stem cells are most commonly identified by staining for cell surface markers, exclusion of fluorescent dyes or labelling with tritiated thymidine [3] . The technology to develop monoclonal antibodies to specific molecules and flow-cytometery based sorting and analysis has been a big driving force in recent CSC developments. Much work has been done to define cell surface markers. It has been shown that two distinct subpopulations can be separated from a single tumour that differ in their cell surface markers and their ability to seed new tumours in vivo. Most of the currently used markers do not recognise functional stem cell activity. By using combinations of cell surface markers, the homogenous purification of stem cells can be obtained [3]. Table 1 below reviews the current suggested markers for some tumour types. The use of animal models has allowed identification and assessment of markers that are expressed by cancer stem cells. The most convincing demonstration of identity CSC s elected by biomarkers comes from serial transplantation of cellular populations into animal models. The CSC containing fraction should re-establish the phenotypic characteristics of the original tumour [48]. In 1997 Bonnet et al showed that the ability to transfer human leukaemias into NOD/SCID mice was retained by a small proportion of cells with the CD34+, CD38- phenotype [46]. The CD44 and CD133 markers have emerged as potential markers of immature epithelial cells for isolating CSCs in several tissue types including brain and prostate. Cells have been isolated from several tumour types and serially transplanted in xenograft models: Breast CD44+ CD24-/low established tumours in recipient mice. Brain CD133+ enriched cells. Prostate Side population CD44+ enriched. In these experiments small numbers of selected cells produced tumours in recipient mice. In this instance CSCs can on

Chaucers View of Women Exposed in The Canterbury Tales Essay -- Geoff

Often, the most memorable female characters are those who break out of the stereotypical â€Å"good wife† mold. When an author uses this technique effectively, the woman often carries the story. In Geoffrey Chaucer's Canterbury Tales, he portrays the Wife of Bath, Alison, as a woman who bucks the tradition of her times with her brashness and desire for control. Chaucer effectively presents a woman's point of view and evokes some sympathy for her. In the author's time, much of the literature was devoted to validating the frailties of women. However, in this story, the Wife is a woman who has outlived four of five husbands for â€Å"of five housbodes scoleying† (P50) is she. She holds not her tongue, and says exactly what she thinks, even if she contradicts others, even Jesus. For in the Bible it states that Jesus â€Å"Spak in repreve of the Samaritan:/‘Thou hast yhad five housbondes,' quod he,/‘And that ilke man that now hath thee/Is nat thyn housbonde'† (P16). Despite this quote from the holy writ, the Wife states that ther are no other arguments â€Å"Eek wel I woot he [Jesus] saide that myn housbonde/Sholde lete fader and moder and take me,/But of no nombre mencion made he [Jesus]--/Of bigamye or of octagamye† (P30). She maintains her position and dismisses the one contention in the Bible by stating in relation to the above quote â€Å"Wat that he mente therby [she] can nat sayn,/But that I axe why the fifthe man/Was noon housbonde to the Samaritan?/How manye mighte she han in mar...

Rhetorical Analysis of “I Have a Dream” Essay

In 1863, Abraham Lincoln oversaw the passage of the Emancipation Proclamation. Although all black slaves were freed by this proclamation, unfortunately, the oppression towards African Americans was far from over. It wasn’t until the mid 1900’s that African Americans took a stand against this ongoing segregation and racism. Amongst all the civil rights leaders that arose during this time, MLK was arguably the most influential figure. Under the leadership of Martin Luther King Jr. (MLK), thousands of African Americans, as well as many of other individuals, marched to Washington D.C. to witness the speech that many people today regard as one of the greatest speeches in history. MLK goes in depth outlining the problems with racism as he simultaneously invokes feeling of sympathy in the audience. Furthermore, through his use of various other rhetorical devices, he generates strong feelings of unity amongst audience members to bring them together as one equal group of people under God. In persuasion, emotional appeal is one of the most powerful devices a speaker can use. If a speaker can effectively force audience members to sympathize with him, they will essentially be on his side of the argument. MLK does a phenomenal job of this in his â€Å"I Have a Dream† speech. â€Å"Five score years ago, a great American, in whose symbolic shadow we stand today, signed the Emancipation Proclamation†¦.One hundred years later, the colored American is still languishing in the corners of American society and finds himself an exile in his own land. So we have come here today to dramatize a shameful condition†. The â€Å"great American† MLK was alluding to was Abraham Lincoln; who, as I stated earlier, was the main driver behind the Emancipation Proclamation. The syntax of this quote really emphasizes the oppression that African Americans are exposed to. Words like exile, languishing, and shameful were chosen to evoke sympathy in the audience for the victimized African Americans. Now that he effectively gained sympathy from the audience, he has their attention. His next move is to drill into their heads that the need for change is imminent. The heavy use of anaphoras in MLK’s speech was his best weapon in regards to making his ideas stick in the heads of audience members. As seen in the portion of the speech, â€Å"Now is the time to†¦make real the promise of democracy†¦.rise from the dark and desolate valley of segregation†¦lift our nation from the quicksands of racial injustice†¦make justice a reality to all of God’s children†, his repetition of â€Å"now is the time to†¦Ã¢â‚¬  stirs up the audience and makes them realize that there is need for immediate actions to be taken to fight this oppression. It was no coincidence that MLK decided to refer to us as â€Å"all of God’s children†. Although the people in the crowd may have differed in skin color, the majority of people were apart of some sort of religion. By putting everyone in the same category (i.e. being children of god) he furthered his point that all men are created equal. When MLK came to speak at Washington D.C., he didn’t come to propose a compromise, he came to preach that African Americans will not settle for anything less than equality. Again, MLK used anaphoras to emphasize and reiterate how relentless â€Å"we† (the African American population) will be in the civil rights movement when he said â€Å"We can never be satisfied as long as†¦our bodies cannot gain lodging in the motels†¦.the colored persons basic mobility is from a smaller ghetto to a larger one†¦our children are stripped of their selfhood†¦we will not be satisfied until justice rolls down like waters and righteousness like a mighty stream†. Along with the repetition of â€Å"we can never be satisfied†, he uses a simile for â€Å"justice† and â€Å"righteousness† to relay the power of the freedom he dreams to achieve for the African American people. Again, through the use of anaphoras, MLK describes this dream he hopes to achieve. In this portion of the speech, he shows the audience a glimpse of the harmonious future that will come with his dream of equality amongst all people. He repeats the phrase â€Å"I have a dream† eight times. His voice progressively got louder and more dramatic as he repeated the phrase. Each time, becoming more powerful than the last. The result of this was a sharp increase in excitement and emotional arousal in the audience. His inclusion of equality and brotherhood in â€Å"we hold these truths to be self evident that all men are created equal†¦.we will be able to sit down together at the table of brotherhood’ were used to invoke feelings of unity in the audience. Unity amongst the American people was not only the dream of MLK, but, along with freedom, was the basis on which America was founded upon. MLK’s repetition of the phrase â€Å"let freedom ring† served to show the audience that, although America was founded on freedom, it hasn’t yet been truly achieved. When true freedom is achieved, he said â€Å"we will be able to speed up that day when all of God’s children, black men and white men, Jews and Gentiles, Protestants and Catholics, will be able to join hands and sing†¦Ã¢â‚¬â„¢Free at last, free at last. Thank God Almighty, we are free at last.’†. He successively appeals to the diversity of the audience by referring to the every major social group and recognizing them all as equal. †. The usage of the diacope â€Å"Free at last, free at last. Thank God Almighty, we are free at last† brings his speech full circle. It presented the end result of the dream he proposed, and successfully expressed the feeling of relief African Americans will have when they get their freedom. In his â€Å"I Have a Dream† speech, MLK went in depth identifying the problems with racism as he simultaneously invoked feeling of sympathy in the audience. His use of various other rhetorical devices generated strong feelings of unity amongst audience members to bring them together as one equal group of people. Although his rhetorical devices were the main reason behind the success of the speech, the way he structured of the speech is what pushed it above and beyond greatness, and made it ones of the greatest speeches in history. MLK was without a doubt, the most influential leader in the civil rights movement. Without his influence, segregation may have still existed even today. However, thanks to his phenomenal rhetorical speaking, his â€Å"I Have a Dream† speech gave the civil rights movement the immense push it needed to end segregation for good.

Diabetes Management in Primary Care - Essay Example It is evident, that paying more attention to the way the management of diabetes is performed, may play for the benefit of the patient in the following ways: As diabetes is one of the most common diseases in the world, and is often hereditary, affecting people of all ages, social and other statuses, this chronic disease should acquire new approach in its primary care. Diabetes mellitus is caused by a deficiency of, or insensitivity to, the hormone insulin, resulting in an inability to control the use and storage of glucose - blood glucose levels therefore rise.   There are two main types of diabetes:    Type 2 diabetes, previously referred to as non-insulin-dependent diabetes mellitus (NIDDM), which results from a relative deficiency of, or insensitivity to, insulin and is more commonly diagnosed over the age of 40. In managing diabetes, especially in its primary care stage, it is essential to remember about the meticulous metabolic control, which is one of the principal ways of preventing the possible complications of diabetes, or at least delaying them. It is, of course, understood, that the bigger portion of these complications may be prevented at the early stage in case they are detected in time and are managed in the proper way. The aims of the primary care in diabetes may be defined in the following way. The main aim of any care system in relation to diabetes, or any other chronic disease, is to provide people suffering from this disease with chances to live quality life as well as to reduce the complications. The keys to achieve these aims are in metabolic control, which should be performed on the constant basis with deep analysis of the received results, as well as the maintenance of the normal glucose level in blood to prevent the complications of diabetes.

Develop a Product - Assignment Example The number of teenagers in the US will grow to 35 million by 2010 and teenagers will spend an average of $80 per week on themselves (The University of Georgia BOS/SBDC Applied Research Division). More and more companies are entering into this industry, however, none of them is targeting the youngsters. Therefore, starting a private health and beauty spot targeting educational institutes in California seems to be a very feasible option. California is the centre of various top educational institutes (Utexas, 2010). By starting a health and beauty spot for students, significant number of universities and schools can be attracted because of the higher competition among schools in California. The proposed Grooming Centre will only target the students from all age groups. An outlet will be established where all grooming and makeover services will be provided. Our centre will offer membership packages to schools, universities and colleges at discounted rates. When a university will become a member of our Salon, the students of that university will be able to take our services at very cheap rates. Grooming Centre and Salon aims to expand its business by getting more and more educational institutes as its members. This business will be a unique service-oriented idea because it will solely target students. Through Grooming Centre services, it is aimed to improve the lifestyle of students. Actually beauty, health medical and wellness were different industries (Robert). Robert also highlighted that 48 percent of the clients visiting salons and beauty clinics are below 35. However, through this new company, I aim to offer these services under one roof to the youngsters. Robert, Benjamin.

Melody in the Middle Ages Essay Example for Free

Melody in the Middle Ages Essay In the early Middle Ages, melodic or textual embellishments added to plainchant were referred to as prosulae. In your own words, summarize the types of plainchant to which prosulae were most often added and the reasons for those additions. The Book of Hymns is one prime example of a prosulae. Plainchant was being sung day in and day out by the monks, who had already added some slight melody, but was still not easy to memorize. By adding some rhythm and separation in syllables throughout the melody, a new way to not only memorize the verses, but also present them, was born. In the early Middle Ages, melodic or textual embellishments added to plainchant were referred to as prosulae. In your own words, summarize Notkers description of how and why he came to add words to melismas, and his teacher Isos response. Notker realized as a young child that he wanted to find a way to remember the words to certain melodies, but with them being so long, he could not. When he came across a man with sequenced verses he was at first excited, but soon disappointed as they did no better than the long, monotonous melodies he remembered as a child. When he decided to add words to these verses and took them to his teacher, Iso, he both appreciated and pitied Notker. He went back and corrected some mistakes pointed out by his teacher, and these changes proved to be successful. The new verses were deemed worthy and copied to a roll for the all of the boys to sing.

Oil Spill Recovery Essay -- Energy Environmental Wildlife Essays

Oil Spill Recovery Can you imagine a world where clean water does not exist anymore? Can you imagine going to your kitchen and seeing black water instead of clear coming out of the faucet? Would you still go to the park if the rivers, lakes, and oceans would turn the color of oil and pollution? Would you still take your kids to see the fish and other living species if they were no longer living and floating belly up? How much would you pay to get the clean rivers, lakes, and oceans back? How much would it cost to get the living organisms living again in the rivers, lakes, and oceans? Maybe it is hard to imagine this world today because it is not as bad, water is not black, and living organisms don’t float bellies up when you walk by, but if we don’t think of the long run consequences of our polluting way of life today this horrible world won’t be so hard to imagine. Water covers about 70% of the Earth’s surface. It is the most valuable natural resource we have. For the most part all living organism require water to live, without water we would not exist. Water pollution is a very huge problem. By polluting our rivers, lakes, and oceans we are harming our planet. Organisms are dying at a very disturbing rate. Our drinking water has become greatly affected as well. There are a variety of causes of pollution they include sewage, fertilizers, wash off deposits, pathogens, petroleum, radioactive substances, heat, and other. The enormous accidental petroleum spills are an important cause of pollution especially along shore lines. Off-shore drilling operations contribute to the pollution pool.

Poes Fall of The House of Usher Essay: Gloomy Images :: Fall House Usher Essays

Gloomy Images from The Fall of the House of Usher In Poe’s The Fall of the House of Usher the narrator first views the house of Usher and perceives a mystery incapable of being solved. Foreboding imaginings keep coming into his mind in spite of rational thinking and reasoning. As he says, there are things beyond our ability to rationalize. He rationalizes that if he could look at things differently or in a brighter light, he might be able to change it, but when he looks into the lake he sees, with even more fear before, a mirror image of the house in all its darkness. The eye-like windows of the house reflect back at him. This paragraph is the epitome of the Romantic movement and the story itself makes many direct and indirect references to Romanticism. Poe's references to Van Weber and Fuseli are direct references to European Romanticists. Poe wrote this story when Romanticism was at its height in Europe. The neoclassic world view had given way to the realm of the emotion. No longer was art or life looked upon as a set of rules that if one followed one could rationalize and make a sense of order out of things. Now, one looked at the emotion beneath the rational. And if that emotion was dark and even evil, it was still beautiful because it expressed a truth. Whereas Hawthorne, in Young Goodman Brown, viewed good and evil as something outside of ourselves, such as a witch or a devil, Poe seems to look within the very soul of man. The first element of Romanticism which Poe seems to incorporate into our paragraph and into the story is the moving away from neoclassic rationality when he says that when he looked upon the house he was "forced to fall back on the unsatisfactory conclusion that . . . the reason, and the analysis, of this power lay among considerations beyond our depth." In the story, he also speaks of abandoning reason in his struggles with fear. Reason does not seem to help here. Reason has gone the way of the neoclassicists. In another part of the story, Poe speaks of the sentience, or consciousness of feeling, of vegetable which seems to grow out of the ordered placement or arrangement of the stones. But the consciousness of feeling does not come until the element of decay and fungi is added to the ordered structure.

Developmental analysis Essay

Abstract This project involves the developmental milestones that one takes throughout life. The overall goal of this paper is to give the reader the understanding that the writer has knowledge about the theories and concept of Human Growth and Development. It will incorporate more about the development and growth of the writer. Information from the writer’s mother about her journey of her pregnancy and if she had any problems with her pregnancy. There will be an explanation from the mother about developmental milestones reached. There are a few early events that took place during the writer’s development it will be showcased in the paper. Finally the conclusion of the paper will focus on the lifestyle behaviors that might influence the writer’s current aging process and if there are any issues exactly how she would address it. Keywords: development, lifestyle, journey, young adulthood, human growth, milestones Developmental Milestones Developmental milestones are important journeys that everyone takes throughout out life. Once a mother first finds out that she is pregnant the child in which she is carrying begins to embark on their journey of life. Everyone does not reach their milestones on target or even at all. Each person is at a different stage in their life, therefore their milestones and journey will vary, from one to the other. My particular journey and development has followed the path of Psychologist Erik Erikson’s psychosocial stages of human development. I am currently between stages five and six. Stage five is identity vs. identity confusion and stage six is intimacy vs. isolation. Although I am a young adult I am still developing and hitting milestones on my journey of life. Mother’s Journey While being pregnant with me my mother speaks that she had no problem during her entire nine months of pregnancy. She did not have any problems until delivery. She was in labor for two days. Her water was broken and at that time I stopped moving down. She did not dilate anymore. Once dilation stopped it was found that the umbilical was wrapped around my neck. Although the cord caused stress and my heart rate to drop while in labor, it did not cause any other known complications once I was born. She was in labor for two days. Milestones Developmental milestones are important in a child’s life. Developmental milestones have a wide range of different functional skills that a child is able to do as they hit certain ages. â€Å"Infancy and childhood are dynamic periods of growth and change† (Gerber, Wilks, & Erdie-Larena, 2010). At each age a child is supposed to reach milestones in their life that would consider them as developing normal. If the child does not reach that particular milestone for their age then they are considered to have a developmental delay. Developmental milestones are associated with a child’s gross motor, cognitive, social, language, and fine motor skills. When a child develops their gross motor skills they are able to walk, stand, and sit. They learn how to use their major muscle groups. When the child reaches the cognitive milestone he or she shows that they are able to solve problems, show an understanding, and reasoning skills. Developing milestones also include language. When a child embarks on certain milestones they will develop abilities such as communication skills, speaking, and body language. Learning how to interact with others, for example peers and family is a social developmental milestone. Milestones are important for children to reach. It is crucial to monitor and watch a child as he or she develops. â€Å"Surveillance involves analyzing the milestones in the context of a child’s history, growth, and physical examination findings to recognize those who may be at risk for developmental delay. A thorough understanding of the normal or typical sequence of development in all domains (gross motor, fine motor, problem-solving, receptive language, expressive language, and social-emotional) allows the clinician to formulate a correct overall impression of a child’s true developmental status† (Gerber, Wilks, & Erdie-Larena, 2010).When a child is delayed in reaching their age milestone  parents and doctors will start to show concerns. Although it can be tough for parents worrying about if their child will meet the milestone, it is a developmental journey that is wonderful and joyous to watch. My Development Erik Erikson was a psychologist who developed the psychosocial developmental stages. â€Å"Erik Erikson’s theory of psychosocial development is one of the best-known theories of personality in psychology. Much like Sigmund Freud, Erikson believed that personality develops in a series of stages. Unlike Freud’s theory of psychosexual stages, Erikson’s theory describes the impact of social experience across the whole lifespan† (Cherry, 2014). Although there were other psychologists such as Sigmund Freud and Jean Piaget who had their own developmental theory, the one who I identify best with is Erik Erikson. After speaking with my parents from what they both remember I seem to hit all my developmental milestones without problems or issues. Trust vs Mistrust â€Å"The first stage of psychosocial development of basic trust vs. basic mistrust, he introduces the word hope which was to become the first human strength or virtue. According to Capps (2012) trust is a sense of dependence and confidence where on the other hand mistrust is caution and uncertainty. From birth to eighteen months Erikson called this stage the trust vs. mistrust. During this time the child develops a trust for people, like their parents or caregiver. When I inquired about what signs or anything significant where I showed trust or mistrust my mother said she had the perfect story. She told me that around six months due to the military my dad had to leave for about five months. Before he left I was very attached to him and cried when he left my eyes. Once he left I became attached to my brothers. When he returned I no longer wanted to go to him. The best way to describe it is that I lost trust in him and he became a stranger to me. It did take a while but eventually I was able to trust him and no longer feared him or had a mistrust for my dad. Autonomy vs Shame and Doubt Erikson’s early childhood stage is known as the stages of the two and three year olds. â€Å"Erikson’s second stage, autonomy versus shame and self-doubt, involves the struggle for personal control and separation from others†Ã‚  (Vogel-Scibilia, et al., 2009). In this developmental stage the child has a control over their physical skills. Best example given by my mother for this one was my potty training. Potty training was a smooth training for me. But when I made a mistake and went to the bathroom on myself I was ashamed and I was no longer proud of my accomplishments. It was just the opposite though if I did not use the bathroom on myself. I was excited and even happier when I received praise. I guess I had a sense of happiness and endeavors. Initiative vs Guilt Erikson’s locomotor stage happens during the ages of three through six. In this stage Erikson called it initiative vs guilt. â€Å"During this period the primary feature involves the child regularly interacting with other children at school. Central to this stage is play, as it provides children with the opportunity to explore their interpersonal skills through initiating activities† (McLeod, 2008).The outcome of the locomotor stage is for the child to gain independence. â€Å"The child takes initiatives which the parents will often try to stop in order to protect the child. The child will often overstep the mark in his forcefulness and the danger is that the parents will tend to punish the child and restrict his initiatives too much† (McLeod, 2008). I can remember this time of my life, like it was yesterday. Around the age of five I felt that I would take the initiative and start pick out my own clothes and also dress myself. The night before my first day of kin dergarten I picked out my clothes and could not wait to dress myself. I prepared everything I needed to be ready for the next morning. The first day I woke up eager and excited to get dress. I did everything right according to my mother, except for putting my shoes on the right foot. But the only problem with that was nobody could tell me I was wrong. I was adamant about putting these shoes on the way I wanted too. My brothers tried to help me but I refused their help. My mother gave up trying and let me walk to the car with my shoes on the wrong foot. When I did make it to the car my feet were hurting and I felt ashamed and guilt. I was ashamed and embarrassed because I was wrong. I felt guilty because I would not let anyone help me and I was acting like it would kill me to let my family help me. The locomotor stage showed me and helped me develop a sense of knowing that it is okay to ask for help. I never need or have to be too proud to get  help with I do not understand. Industry vs Inferiority â€Å"The fourth stage is industry versus inferiority and children try to hone and master culturally important skills. The achievement of these skills results in a sense of industry and the psychosocial strength of competence† (Dunkel & Sefek, 2009). It focused on age six to twelve. The outcome in the latency stage is the industry vs inferiority. Erikson set this stage for the school age children. He believed that during this time school age children learn new skills. They are going to learn how to deal with success or suffer with the possibility of failure. If a child is not able to learn their new task or study, they have to understand that there is a chance that failure will occur. I really cannot remember an example that occurred in this stage for me. However I do know what it is like to learn or know about failure. At this age I was learning new things and understanding many different life lessons. I recall in the 7th grade I had to write an essay about black history mont h. Although I thought I knew a lot I quickly found out that I did not. In the third grade I won an award for writing a black history essay. Well in the sixth grade I just knew that I would succeed and win again, I was sadly mistaken. I learned and improved my writing skills but I had to experience failing. I felt a sense of incompetence when I did not win. During this developmental milestone it took me awhile to learn and understand that I was not perfect and I would not succeed in everything I did and would do. But overall the journey that I took was great and I would later find out that anything I wanted to do was possible. This stage helped shape me and get me thus far. Identity vs Role Confusion â€Å"According to Erikson, adolescence was the time when young people were given opportunities to reflect on what career they would choose, what kind of social and romantic relationships they would enter into, and what values and beliefs they would hold† (Schwartz, Zamboanga, Meca, & Ritchie, 2012). The way Erikson explained the adolescence and young adult stages fits me to a tee. Even though the adolescence and young adult stage are spoken about separately they both describe me as I am right now. Erikson described the adolescence stage as the identity verses role confusion. It usually occurs during ages twelve to eighteen. At the stage the developmental goal is for  the adolescent to learn how to obtain and maintain relationships. The relationship that is developed is between the adolescent and their peers. In most cases the adolescent learns how to identify their role and identity. Intimacy vs Isolation Currently the young adult stage that Erikson described is where I am supposed to be in life. It is the developing milestone where the young adult ultimate goal is to have a love relationship. It deals with ages nineteen to forty. â€Å"Erik Erikson spoke of intimacy as a stage of young adulthood that everyone must negotiate, via faithfulness to commitments and readiness for sacrifice† (Torrens, 2009). As a young adult you are trying to develop your relationships with your love ones. Such as your significant other. This is the time that the young adult must understand how to love or they will feel left out as if they are isolated. According to McLeod (2012) when this stage is completed successfully it will lead to a calm and relaxed relationship, a sense of commitment, and a care within the relationship. If one avoids the intimacy and isolates themselves it can and will lead to isolation, loneliness, and sometimes depression. My Current Development I find myself in between the adolescence and young adult stages. Although I feel successful at developing relationships with my peers, which is the ultimate goal of adolescence, I still feel as if I have not identified exactly where I want and need to be, career wise. I am still learning myself and finding out who I am. Ever since I was in the adolescence stage I seem to have been trying to figure out my life and what it is I want to do with myself, career wise. In some moments and instances I felt as if I did not have the friends and relationships I deserve or should have. When I finished college I knew I wanted to work with the County Bureau of Investigations. When I applied and was turned down I figured that something was wrong. I was not mastering this milestone as I should have. I then started working with clients who suffer from mental disabilities. It was a just a stepping stone job that was supposed to get me through until I was able to become an investigator. Four years later I was still working with clients and not my dream job. Still loss and confused I started working at child support. I am still there to this day and feel like I am still confused and not sure  exactly what I need to be doing, as far as occupation. According to the theory of Erik Erikson’s psychosocial stages I am in the young adult stage. I feel that I am not quite there with developing the intimate relationship. Although I have been in a relationship for a while I still feel like I am isolated. I have not completed this stage and still have a few years to go before I am there. Both the adolescence and young adult stages I did not succeed with ease. It is taking me longer to get through these developmental stages. The two stages are helping me to become the young woman and adult I am supposed to. It is just taking me much more time. Currently in my life I am stuck between the two. I have had several disappointments and mistakes in both stages. I have associated myself with the wrong crowd to now working with individuals who want something in life and I feel can help me succeed. I am still a work in process. Spiritual Development â€Å"The inattentiveness to spiritual development in the mainstream social sciences can be graphically illustrated in the study of development psychology† (Roehlkepartain, Benson, King, & Wagener, 2005). Spiritual development takes time to understand. Therefore when it comes to the younger adults it is important for them to understand and form their own spiritual opinions. I have never been a big person on spirituality or religion. Overtime I have started to understand, believe, and accept my spiritual development. Spiritual development is a physiological and psychological movement in one’s life. For me I am growing stronger mentally. Being spiritually developed relieves a person of harmful toxins. A person is able to become healthier and stronger. Although I have begun the process of developing spiritually, I am far from there. I have a lot of hurdles to climb before I am able to say that I have developed spiritually. â€Å"But grow in grace, and in the knowledge of our Lord and Saviour Jesus Christ. To Him be glory both and forever† 2 Peter 3:18 Conclusion In conclusion, developmental milestones are important for everyone. Everyone is not going to make it through all the milestones with ease. There will be bumps and bruises along the way. Even though Erik Erikson psychosocial best describes me there are other psychologist that one may feel more connected  too. Erikson’s stages explain my journey and I am able to see my way through. References Capps, D. (2012). Erikson’s schedule of human strengths and the childhood origins of the resourceful self.
