Siop ELL - Research Paper Example Developing Connections Waterman and Harry (2008) present ten recommendations to guide school staff on how to implement this connection, where we emphasize on: (1) school principals providing explicit support for parent involvement work, (2) offering open-ended meetings involving teachers and parents, and (3) offering parents an English as a second language class or a family literacy program (9-13). The school principal promotes parent-school collaboration through policy, staff decisions, and behaviors (Waterman & Harry, 2008, p. 9). These can be exemplified by being highly concerned with the parents’ questions in meetings, and hiring staff that could work and communicate well with ELL families. In addition, initiating open-ended meetings for parents and select school staff is an avenue for both parties to discuss questions and concerns, and for parents to familiarize the school system, and for practitioners to be aware of the ELLs experiences (10). These assemblies would event ually create a trusting relationship between the school and families, increasing parental involvement.

Global, political economy - Essay Example The many a vehicle of modernisation, international diplomacy and economic dynamism of countries catapult a certain degree of prosperity that is felt worldwide. Scope of Globalisation The phenomenon of globalisation affects society's economics and politics. Its primary processes include the forces that govern improvements in technology, advancements in transportation services, increased employment and income opportunities, and cohesive intercontinental economic cooperation (Jaffe, 2006). Most countries in the world witnessed rapid developments in the area of business in the past few decades. A global village has been created to formally launch an avenue where countries can enter economic agreements. Globalisation has been said to be at the forefront of these modern-day events. On the other hand, several critics consider globalisation as a disease rather than a solution (Kalb, et al., 2004). Most people, including numerous world leaders, deem it an organized procedure that connects com munities around the world to participate in a synchronised development process. In essence, the whole gamut of globalisation revolves around contemporary structures such as Information and Communication Technology, Trade Democratisation, Free Market, and diplomatic agreements that are openly participated in by all countries (Lawal, 2006). Employment-generating Activities Globalisation remains one big precursor for the exponential growth of employment opportunities among developed and developing countries. Due to the expanding consumer markets worldwide, various industries responded to the call of ‘supply and demand.’ Countries with robust workforces tremendously benefit from these activities, while other nations strategise themselves to be at par with their rivals. Such a healthy competition prompts the international community to generate quality products and outputs based on the labour of their citizens. Economic literature upholds that unemployment rates are primarily dependent on the domestic policies of governments (Kollmeyer, 2009). This fact incited political leaders and fiscal analysts to intensively study their economic regulations to perfectly suit the recent trends (Rama, 2003). For countries that formulate intelligent decisions on how to boost employment rates for their people, success is at bay. While countries that make the wrong decisions suffer greatly (World Bank, 2009). Empiric data confirmed that globalisation has a positive impact on countries where human capital is above average. In some African countries, wages are projected to increase for skilled workers, especially in the light of rising demand due to technological advances (World Bank, 2009). Increased Income The relationship between employment and income were noted by several economic authorities (Lecaillon, 1984; International Labour Office, 2000). Recent studies suggest that globalisation is also a massive contributing factor to the increase of income among workers worl dwide (Mishkin, 2008). Even though there is a disparity of income distribution among countries, the fact that wages are solely based on the skills of workers cannot be downplayed in the aspect of a globalised workforce. It was noted that the skilled industries and the advanced production mechanisms of developing countries are likely to have a strong impact on their competitive advantage (Sachs,

The First Great Debate Challenges To Realism Politics Essay

The First Great Debate Challenges To Realism Politics Essay The subject matter of International Relations as a branch of political science can be defined in different ways. As in most social science disciplines there is no scientific consensus on the field and thus the definition we adopt would be conventional and reflect a particular account of the world.  [1]  Since there is no common definition of international relations, there exist multiple theories explaining the principles of interplay of what each of them consider being main actors would it be states, non-state institutions or classes. C. Brown and K. Ainley argue that there are no right or wrong theories as all have political implications, therefore, the pluralism of contesting theories each presenting different perspective should be preserved.  [2]   The aim of this essay is to examine the work by Ole R. Holsti  [3]  Theories of International Relations and critically address the arguments he presents. In the course of this essay I will briefly summarize authors description of state of affairs in international relations theories complementing it with personal interpretation. Holsti assumes the main aim of his essay is to contribute to exchange of ideas between political scientists and diplomatic historians.  [4]  The text addresses diplomatic historians to introduce them theoretical approaches used by political scientists. Author describes the first great debate on theories of international relations namely challenges presented by different groups of models to classical and modern realism.  [5]  He classifies theories that challenge realist concepts on system level into three groups: Global Society/Complex-Interdependence/Liberal-Institutionalism, Marxist/World System/Dependency and constructivism, neglecting differences inside these groups to emphasize main differences between theoretical perspectives.  [6]  He also examines several decision-making models that go beyond structural analysis of international relations focusing on political processes inside the units of the system.  [7]   The Great Debate In this chapter I am going to summarize five major arguments of realist theories from classical to neo-realism described by Holsti and their critics by other international relations theories on systemic and decision-making levels. Although it might seem very simplistic, if one could generalize the five points of classical realist theory described by Holsti  [8]  into one sentence, the result might be the following: Sovereign states as main units of the anarchical international system act as unitary rational actors to achieve security through involvement into war and peace based on relative capabilities. In the first place, Holsti states that classical realists consider as central questions the causes of war and the conditions of peace  [9]  , arising from the structural anarchy of the international system, meaning that there is no higher authority above states to settle conflicts. This kind of structural organization of the international system gives rise to the security dilemma that is attempts to reach absolute security by one state is in direct proportion to insecurity of all other parts of the system.  [10]   Each of the five points made by classical realists were further developed and complemented by modern realist or neo-realists, namely K. Waltz and later R. Gilpin, but equally they all seem to hold numerous controversies. At first glance, it appears to be that the assumption of rationality of states is based on, I would argue irrational by itself pessimistic concept of human nature would it be secular or religious.  [11]  Moreover, the whole approach to explanation of international relations in terms of military struggle for security (can easily be substituted by superiority) against all other states may lead to a conclusion that there is constantly a world war all against all. Fortunately however this is not the case. Furthermore, Holsti points that Robert Gilpin developed the argument that international system is in a state of equilibrium if no state believes that it is profitable to attempt to change it.  [12]  Therefore, it appears to be that the question of engagement in a war is defined solely by mathematic correlation between costs and benefits. Would this neo-realist assumption be true, the most powerful states would have been involved in constant expansion until one of them achieves an empire comprising the entire world. The aforementioned controversies of the realist theories show us that there should be more complex motivation in the relations between actors in international relations. Apart from the involvement in war or peace, states are likely to cooperate on a number of issues like trade, science, education, migration, environmental challenges etc. Even the most powerful states are currently unable to cope with some issues that are cross-border like terrorism or spread of epidemic diseases.  [13]  The increasing interdependence of states and growing influence of non-state actors like NGOs, transnational corporations and international organizations in contrast to decline of the nation-state are the main arguments of the group of theories labeled by Holsti as Global Society/Complex-Interdependence/Liberal Institutionalism. State remains the point of departure for these theories, but the views on its future role vary from acknowledgment that state is a major source of change in the internation al system to its irreversible decline.  [14]   Despite encompassing broader range of motivations, except war and peace that determine international relations, the latter group of theories presents just another perspective with its limitations and inability to explain certain tendencies currently taking place in the world. Together with integration processes and interdependence, we can observe rise of nationalism and disintegration in different parts of the world, especially in the Central and Eastern Europe. Marxism/World Systems/Dependency together with post-modernist theories are rare cases where Holsti expresses his own standpoint apart from impartial description of previous groups of theories, using satirical remarks.  [15]  Holsti describes the arguments of this group of theories very shortly. Marxism/World Systems/Dependency theories consider as determining factor of international relations the mode of production and inequality inside the world capitalist system. According to M/WS/D models, the role of state is secondary in relation to classes. On condition that one accepts Marxist paradigm and his interpretation of capitalism, the explanation of international relations based on exploitation within one world capitalist economy seem convincing. The system cannot be anarchical, if one of the parties depends on other. However, at least one problem appears in this regard related to Marxist interpretation of actors in the international relations classes. The criteria for defining classes are more or less clear the relation to the means of production, place in the system of production and distribution. The problem is that the exploited across the world do not necessarily define themselves as proletariat and do not realize the need for workers solidarity. Thus, they cannot act as an independent actor in international relations. Constructivism challenges all the systemic theories of international relations by demonstrating that all notions developed to explain reality are socially constructed, thus, cannot be considered as consequence of the system. The behavior of actors is determined by the way they perceive the reality, not by reality itself.  [16]  I agree with Holstis argument that constructivism is rather an approach than a theory and can contribute to expanding other theories of international relations.  [17]   Finally, Holsti shows the importance of decision making models in international relations. Certain decisions may be taken or not, depending on the inforrmation acquired and processed within the actors. This proves the importance of consideration together with systemic factors also internal conditions of actors in international relations theories. Conclusion The theories discussed by Holsti represent different approaches to explaining international relations. Each of them presents their view why the states or other actors behave like they do and only in that way. All of the theories tend to universalize and explain the relations between states in terms of simple models. My standpoint is that there cannot be a single universal pattern in which the whole diversity of global processes will fit. This is why none of the theories of international rlations is appropriate to be the theory of globalization. However each of them can be useful in research of certain aspect of globalization. For example, structural realism is considered to be ahistorical, nevertheless, it can be applied to the research of conflicts. Other theories may be used to study complex interdependencies and entanglements in the world. The globalization research should be based on a certain theory, but this theory cannot be limited to one perspective. The most important, I believe, is to take into account different perspectives and approaches in the study of globalization. Therefore, none of them can be priviledged or neglected as they are based on the socially constructed notions.

The Blind Husband in Carver’s Cathedral :: Carver Cathedral Essays

The "Blind" Husband in Carver’s Cathedral  Ã‚   The short story "Cathedral" by Raymond Carver is about a woman who has a blind friend who comes to visit her and her husband. Although the husband has, technically, normal vision he is in the beginning of this story the one who is "blind." Through the husband’s words and actions when he is dealing with Robert, the blind man, we can see that the husband does not "see" or understand what Robert’s blindness means or how it changes or does not change him as a human being. At first Robert makes the husband very uncomfortable, for the husband does not know what to say or do around the blind visitor. As the story progresses, we can see a change in the husband; he seems to be able to see Robert as a person and not just as a blind man. One example that shows the husband is "blind" comes in the beginning of the story, before Robert arrives. When the husband and wife talk about Robert, the husband usually refers to him as "this blind man" (1052), and he never uses Robert’s name or assigns any human attributes to him. This shows that the husband does not really see Robert as a person, but just as a blind man who is different because he has a handicap. When Robert arrives at the couple’s house, the husband does not know what to say to him. The husband asks stupid questions about the view from the train: "Which side of the train did you sit on?" (1055). The husband knows that Robert cannot see the view, but he asks him these questions anyway. Also, the husband thinks to himself, "I didn’t know what else to say" (1055) which is a clear indication that he does not know how to relate to Robert. Both of these quotations show that the husband does not know what to talk about with Robert because he only sees Robert’s handicap, instead of seeing him as a complete human being who has emotions, thoughts, ideas, and beliefs. Not only does the husband not know how to communicate with Robert, he does not how to act around him either. A good example of this, shown after dinner, is when all three of them go into the living room. This is how the husband portrays what happens when they first enter the room: "Robert and my wife sat on the sofa.

Loneliness Theme in ‘Of Mice and Men’ Essay

Loneliness is the feeling of isolation – Steinbeck achieves this theme by portraying effectively through key fictional characters in ‘Of Mice and Men’. By living in the town of ‘Soledad’ (Spanish for loneliness), the audience gets an overwhelming sense of the depressing environment that the migrant workers are living through by their repetitive lifestyle and the consequences they face through the Great Depression (1930’s – 1940’s) and the Dustbowl. Even through hard work and prosperity the American dream is unattainable. The four loneliest personas in this novel are Curley’s wife, Crooks, Candy and George + Lennie. Even though they all want to strive for success, and achieve the American dream: the idealistic fantasy of individual freedom, independence and self-reliance they all have to face loneliness to get there. The theme loneliness is most bitter in Crook’s character. Crooks was introduced in chapter 4 and the first word used to describe him: the negro clearly tells us that he is isolated due to race which leads us to the theme of loneliness, in those days black people were always separated and discriminated because of the segregation law. He is also housed with the animals treating him like he is one of them. This is shown by Steinbeck’s language of setting as Crooks lives in a ‘little shed that leaned off the wall of the barn’ to indicate that he is weak to survive in the world. He also has ‘a mauled copy of the California civil code for 1905’ which conveys that despite Crooks being motivated and strong to achieving a prosperous life, his life will never be the same. The past has gone behind him and nothing can protect him from his isolation and loneliness. Although Steinbeck shows that loneliness has made Crooks bitter by putting Candy and Lennie in the same position as he is making Lennie think if ’s’pose you don’t have nobody’ As well as this, his race makes him more vulnerable and exposed to others easily. â€Å"S’pose you didn’t have nobody. S’pose you couldn’t go into the bunk house and play rummy ’cause you was black. How’d you like that? S’pose you had to sit out here an’ read books. Sure you could play horseshoes till it got dark, but then you got to read books. Books ain’t no good. A guy needs somebody-to be near him. A guy goes nuts if he ain’t got nobody. Don’t make no difference who the guy is, long’s he’s with you. I tell ya, I tell ya a guy gets too lonely an’ he gets sick†. Steinbeck says this to show us that race was the main reason why Crooks was lonely and isolated and that he would work for nothing, as long as he could communicate with others. Curley’s wife is lonely in many ways. She is flirtatious with many of the men on the ranch because she feels trapped in a world of men and a marriage which lacks love and companionship. She was born lonely and women were considered as disability in 1930’s America, which is harsh but Steinbeck shows this very effectively. Curley’s wife`s appearance may make her as an extremely attractive person, having ‘full rouged lips and wide-spaced eyes’ and her American dream makes her all the more vulnerable to her loneliness. â€Å"Think I don’t like to talk to somebody ever’ once in a while? †Why can’t I talk to you? I never get to talk to nobody. I get awful lonely† shows us that she would like to talk to someone once in a while and is really lonely in this ranch world where there is no one to support her. What makes her more exposed is the constant red imagery used in her appearance which not only represents a desire for rom ance in her life (which is failed by Curley for her loneliness has made her disappointingly upset) but also a sign of warning and danger in her life. Not only this, but Curley’s wife is vulnerable because she has no name which in a sense suggests that she has no strong identity on the ranch and is treated as a social accessory. So similarly to Crooks, her loneliness has made her bitter and more masculine which is shown towards the end of Chapter four and is now treated as ‘ma’am’ by Crooks. Candy is a prime representation of isolation and loneliness. Firstly, it seems his disability has brought him down by the ranchmen because he lost his right hand which shows that he isn’t practical in the ranch. He’s the oldest on the ranch by being a ‘tall, stoop-shouldered old man’ and having the most experience on the ranch. Yet it seems that the depression has hit on the shoulders for his look on life has been brought down knowing it seems that age and disability has made him vulnerable against the harsh reality of isolation in 1930’s America. Secondly, he lost his only trusted co mpanionship because of old age and decay so now he’s really vulnerable and thinks that he is going to die soon as well because of his old age- â€Å"You seen what they done to my dog tonight? They says he wasn’t no good to himself nor nobody else. When they can me here I wisht somebody’d shoot me†¦Ã¢â‚¬  â€Å"And they give me two hundred and fifty dollars ’cause I lost my hand. An’ I got fifty more saved up right in the bank right now. That’s three hundred†¦Ã¢â‚¬  He is easily willing to give every penny that he is worth to join in George and Lennie’s dream and break his intense loneliness in his life and leave behind his isolated painful ranch life. Contrasting with all these characters, George + Lennie are a strong companionship coming into the ranch with high expectations. However George feels like he has a burden on his shoulders and has to take care of someone who doesn’t have the same mental ability like him. So, for him it feels like a job rather than a partner or a friend that will give him courage and hope in the future. His dream about his farm is his attempt to breaking the loneliness in his world. â€Å"Guys like us that work on ranches are the loneliest guys in the world. They got no family. They don’t belong to no place†, â€Å"I seen the guys that go around on the ranches alone† by these two quotes Steinbeck suggests that the ranch itself is a lonely place and with that the characters are lonely themselves which builds up the isolation. Furthermore Lennie’s desire to pet soft things comes from his need to feel safe and secure, to touch something that gives him that feeling of not being alone in the world. For Lennie, the dream of the farm parallels that security. Lennie is not alone, he knows that he has George to take care of him and says that George would never leave him no matter what. He is not as lonely as other characters but is still afraid and sacred of this world which he can’t cope with. Even though George and Lennie are always together they are still lonely because George is like a care taker and for Lennie, George is like a boss and a person to take orders from rather than a companion. Overall, George + Lennie, Curley’s Wife, Crooks and Candy are affected by the harsh reality of loneliness which Steinbeck presents emotionally through setting and their own disabilities in 1930’s America- whether it’s racism, sexism or not able to perform practical skills. Even with their American Dream, Steinbeck shows that this only makes them the more vulnerable against the wide world ahead of them within a lonely town known as ‘Soledad’. We see this isolation come altogether in Chapter 4 when the ranch hands go into town on Saturday night to ease their loneliness with alcohol and women. Similarly, Lennie and Candy go into Crook’s room to find someone to talk to, and later Curley’s wife comes for the same reason – Loneliness.

Review of All the King’s Men

The nature of Jack Burden`s journey from the `arid land of facts` to the `dream sea of ideas` is what the story is all about. It goes on to spell whether the journey undertaken by the hero is indeed a spiritual one or an attempt at self-discovery.An attempt has been made to explore the roots of this journey through Modernism (the breakdown of philosophical/moral consensus about the nature of things, the turn toward myth) and Neo-Romanticism (the search for a new unifying principle amid the fragmentations of Modernity/Scientific Materialism), the role of Willie Stark, Ellis Burden, Judge Irwin, and the hero’s journey through the turmoil and pleasures of life.The story revolves around the relationship between the themes of Death and Rebirth which occur in Jack’s journey through incidences of tragedy and beyond. It ends on a note of positivism, when the hero, Jack Burden, transforms himself from being a pawn to his roots in ancestral lineage. Literature Review ‘All t he King's Men’, is the story of the rise and fall of Willie Stark, a political titan in the Deep South, who during the 1930s rose from hardscrabble poverty to become the governor of his state, and ultimately it’s most powerful political figure.The story goes on to say how Willie, the anti-hero blackmails and bullies his enemies into submission, and using his good office institutes a radical series of liberal reforms which are designed to tax the rich and ease the burden of the state's poor farmers. This leads to a conflict of personalities which includes the notable former governor, Sam MacMurfee, and other power mongers. Jack Burden, the scion of one of the state's aristocratic dynasties, turns his back on his genteel upbringing, against the wishes of his well-wishers, which includes the influential Judge Irwin.Throwing caution to wind, Jack joins Willie on his journey to stardom, earning him the name as, Willie’s right hand. Willie takes advantage of Jack†™s talent as a historical researcher to dig up the unpleasant secrets of his enemies, using this to blackmail and provocation. Cynical and lacking in ambition as he is, Jack walks away from many of his past interests; the dissertation of American History, and marriage to Anne Stanton, the daughter of a former governor of the state.The scene when Willie asks Jack to look for skeletons in the closet of Judge Irwin, Jack is forced to confront his ideas concerning consequence, responsibility, and motivation. He discovers that Judge Irwin had accepted a bribe, and that Governor Stanton, his would-be father-in-law, had covered it up, resulting in Judge Irwin's suicide. The story then turns to another interesting episode of Adam Stanton, Anne’s brother, taking up the directorship of a new hospital being built by Willie.The vicious turn of events leads Willie to Anne, who unsuspectingly has an affair leading to his ultimate murder. Jack, with nothing to gain returns, an empty man. In this we see, the death and rebirth of Jack through his tryst with destiny and forlorn countenance of Anne transform to one of exuberance. Willie's death at the hands of Adam, his loyal employee, jolts Jack to such an extent that he is left dumbfounded and brooding of the consequence of his future and a rethink of his belief.Jack returns to his senses and takes a major plunge towards society by accepting his long lost love, Anne Stanton, and pursues his passion of research . 3. 0 Analysis Jack’s journey from the ‘arid land of facts’ to the ‘dream sea of ideas’ can be best described as a journey towards truth which is emphasized when he says, ‘And all times are one time, and all those dead in the past never lived before our definition gives them life, and out of the shadow their eyes implore us. That is what all of us historical researchers believe. And we love truth. ’It may be seen that the principal characters in the novel Willie Sta rk, Judge Irwin, Anne Stanton though their personal lives have not been free from blemishes, they were in more than a way, corrupt. Starting with his association with Willie to the displeasure of his near and dear, the moment he learns of the affair of his first love Anne Stanton with Willie, and to the moment he learns of Judge Irwin’s suicide, Jack had never endured a sign of negativism in Willie’s actions. It is only when Jack’s mother reveals the true identity of his father, does Jack admonishes Willie for his deliberations, although not in public.This incident leads Jack through many a twist and turn in his endeavor to get to the bottom of Willie’s motives. The sequence of events that followed, leading to the untimely murder of Willie, inculcated a sense of disbelief, and revulsion in him. The trudge back to his roots exemplifies the struggle and worship of humanity in all its glory. Jack for all his wiles, was an ardent follower of his master. Willi e Stark, ‘the Boss’ gave the impression of a man on the move. Never, did he pause to gauge the consequences of his actions. This ultimately led to his doom.Willie Stark, though he had a humble beginning, rose to a position of wielding unbridled power in the process subjugating his opponents by brute force and of course putting to use the investigative skills of Jack. Judge Irwin, revered as a father figure by Jack, has not been in the good books of Willie, who instigates Jack to dig into the past activities of Irwin, protested vehemently by him. However, when the facts were unearthed, a shocked Jack and a bemused Willie confronted Judge Irwin. Judge Irwin was a man of honor. He was known to be a very straight man and never took the law into his hands.This revelation was too much for him to digest, and equally embarrassing, that he did what a man of his stature would have done, commit suicide. Strangely, for most part of the story, Jack believes that Ellis Burden, whom h e refers to as his Scholarly attorney, to be his father, where in fact, it is Judge Irwin who is the real biological father. Ironically, Jack gets to know this only after the suicide of Irwin, which Jack believes was because of his action. Jack’s aristocratic moorings unfortunately does not refrain him from joining hands with the immoral Willie Stark as we see in the story.Though Willie uses Jack as a formidable tool in his ascent to power, using Jack’s research skills to his greatest advantage of subjugating his opponents, was a crime most unsuspecting of such a character. Jack becomes a witness to Willie’s Machiavellian manipulations and misdeeds, albeit, unwittingly. However Jack’s shunning politics at the end of the story and his return to his earlier passion is a metaphor for Jack’s return to his roots, his history, and his American past. In fact, Jack’s research revolves around his study of the life of Cass Mastern, a man of high moral standards and a student at Transylvania College in Kentucky.Even the subject Jack takes up for his dissertation is a reminder to the readers of Jack’s search for the truth. ‘Is death the last sleep? No, it is the last and final awakening,’ said W. Scott, a stark reminder synonymous of the characters in this book; Judge Irwin’s suicide when he is confronted by Jack with facts about his acceptance of a bribe, and the killing of Willie Stark by Adam Stanton. While for the major part of the story Jack believed that the ‘Great Twitch’ denoted actions in life and not words or deeds.The awakening on that morning at home, brought Jack to retract his thoughts on life, and once again believed that men were responsible for their actions and deeds. This rethinking in a sense is responsible for Jack’s decision to marry Anne Stanton (a metaphor for rebirth) despite his knowledge of the fact that he she had an affair with Willie Stark. Reflecting phi losophically he says, ‘all the words we speak meant nothing and there was only the pulse in the blood and the twitch of the nerve, like a dead frog's leg in the experiment when the electric current goes through, a true reflection of Modernism.This can be, in a philosophical sense be equated to the death of Jack figuratively, since Anne was Jack’s first love, whom he loved more than anything else in the world. 4. 0 Conclusion In the ultimate analysis it may be inferred that Jack’s life has been a life of journey towards the truth, towards his roots and eventually his self-discovery. The main characters in the story play an important role in molding Jack’s character, the incidents in the lives of those characters enlightening the path Jack has taken to achieve his goal. 5. 0 Bibliography 1. 0 www. sparknotes. com/lit/kingsmen/summary. html

Christianity and Homosexuality essays

Christianity and Homosexuality essays During the last 2,000 years of Christianity many changes have taken place in how it sees people and their place in the kingdom of God. The Church has changed its views of people of other races as inferior, or savages, in need of salvation. They have changed their views on womens equality. They are even in the midst of making amends with and reaching out to Muslims and Jews. But most modern Christians have a more hardened view of homosexuals than they*ve ever had. Some see homosexuals as being in direct league with Satan, as they also believed about "witches". Gays are seen as a direct threat to society and to the sanctity of the family. Homosexuality is referred to as an abomination. Next to abortion, nothing seems to unite Christians more than the fear of homosexuality. On what basis do Christians form their ideals and fears of gay people? Why do they feel the need to demonize and disenfranchise an admittedly small segment of the population? Why does the Church work so hard to prevent equal rights for gays, and for that matter, to prevent homosexuality at all? These are the questions I hope to answer. I could simply answer these questions by saying that some people are just ignorant. But I believe that nearly all Christians who dislike gays believe that they have a very strong basis for feeling the way they do. One of the first reasons that these people will give is that the Bible says homosexuality is a sin. The Bible gets the blame for a lot of things but especially for outright rejection of homosexuals. Genesis, Leviticus, and Romans tend to be the books most referrenced by those arguing the sin of "sodomy". Another reason for Christian rejection of homosexuality is that it is unnatural. Once again the Bible tends to be the basis for this concl usion, although for different reasons. Any sex act that cannot achieve procreation is seen as being against nature, as in the case of Onan. This going against the grain of nature has ther...

Understanding Critical Theory

Understanding Critical Theory Critical theory is a social theory oriented toward critiquing and changing society as a whole, in contrast to traditional theory oriented only to understanding or explaining it.  Critical theories  aim to dig beneath the surface of social life and uncover the assumptions that keep us from a full and true understanding of how the world works. Critical  theory emerged out of the Marxist tradition and it was developed by a group of sociologists at the University of Frankfurt in Germany who referred to themselves as  The Frankfurt School. History and Overview Critical theory as it is known today can be traced to Marxs critique of the economy and society put forth in his many works. It is inspired greatly by Marxs theoretical formulation of the relationship between economic base and ideological superstructure and tends to focus on how power and domination operate, in particular, in the realm of the superstructure. Following in Marxs critical footsteps, Hungarian Gyà ¶rgy Lukcs and Italian Antonio Gramsci developed theories that explored the cultural and ideological sides of power and domination. Both  Lukcs and Gramsci focused their critique on the social forces that prevent people from seeing and understanding the forms of power and domination that exist in society and affect their lives. Shortly following the period when  Lukcs and Gramsci developed and published their ideas, The Institute for Social Research was founded at the University of Frankfurt, and the Frankfurt School of critical theorists took shape. It is the work of those associated with the Frankfurt School, including Max Horkheimer, Theodor Adorno,  Erich Fromm, Walter Benjamin, Jà ¼rgen Habermas,  and Herbert Marcuse, that is considered the definition and heart of critical theory. Like  Lukcs and Gramsci, these theorists focused on ideology and cultural forces as facilitators of domination and barriers to true freedom. The contemporary politics and economic structures of the time greatly influenced their thought and writing, as they existed within the rise of national socialism, including the rise of the Nazi regime, state capitalism, and the rise and spread of mass-produced culture. Max Horkheimer defined critical theory  in the book  Traditional and Critical Theory.  In this work, Horkheimer asserted that a critical theory must do two important things: it must account for the whole of society within a historical context, and it should seek to offer a robust and holistic critique by incorporating insights from all social sciences. Further, Horkheimer stated that a theory can only be considered a true critical theory if it is explanatory, practical, and normative, meaning that the theory must adequately explain the social problems that exist, it must offer practical solutions for how to respond to them and make change, and it must clearly abide by the norms of criticism established by the field. With this formulation Horkheimer condemned traditional theorists for producing works that fail to question power, domination, and the status quo, thus building on Gramscis critique of the role of intellectuals in processes of domination. Key Texts Texts associated with the Frankfurt School focused their critique on the centralization of  economic, social, and political control that was transpiring around them. Key texts from this period include: Critical and Traditional Theory  (Horkheimer)Dialectic of the Enlightenment  (Adorno and Horkheimer)Knowledge and Human Interests  (Habermas)The Structural Transformation of the Public Sphere  (Habermas)One-Dimensional Man  (Marcuse)The Work of Art in the Age of Mechanical Reproduction  (Benjamin) Critical Theory Today Over the years, the goals and tenets of critical theory have been adopted by many social scientists and philosophers who have come after the Frankfurt School. We can recognize critical theory today in many feminist theories  and feminist approaches to conducting social science, in critical race theory, cultural theory, in gender and queer theory, and in media theory and media studies.

Branched Chain Alkane Definition

Branched Chain Alkane Definition An alkane is a saturated hydrocarbon. Alkanes may be linear, branched, or cyclic. Heres what you need to know about the branched alkanes. Branched Alkane Definition A branched chain alkane or branched alkane is an alkane which has alkyl groups bonded to its central carbon chain. Branched alkanes contain only carbon and hydrogen (C and H) atoms, with carbons connected to other carbons by single bonds only, but the molecules contain branches (methyl, ethyl, etc.) so they are not linear.   How to Name Simple Branched Chain Alkanes There are two parts to each name of a branched alkane. You may consider these parts as prefix and suffix, branch name and stem name, or alkyl and alkane. The alkyl groups or substituents are named in the same way as the parent alkanes, except each contains the suffix -yl. When not named, alkyl groups are represented as R-. Here is a table of common substituents: Substituent Name CH3- methyl CH3CH2- ethyl CH3CH2CH2- propyl CH3CH2CH2CH2- butyl CH3CH2CH2CH2CH2- pentyl Names are constructed in the form  locant  Ã‚  substituent prefix  Ã‚  root name according to these rules: Name the longest alkane chain. This is the longest string of carbons.Identify the side chains or branches.Name each side chain.Number the stem carbons such that the side chains will have the lowest numbers.Use a hyphen (-) to separate the number of the stem carbon from the name of the side chain.The prefixes di-, tri-, tetra-, penta-, etc. are used when there is more than one alkyl group attached to the main carbon chain, indicating how many times the specific alkyl group occurs.Write the names of different types of alkyl groups in alphabetical order.Branched alkanes may have the prefix iso. Examples of Branched Chain Alkane Names 2-methylpropane (This is the smallest branched chain alkane.)2-methylheptane2,3-dimethylhexane2,3,4-trimethylpentane Different Methods of Representing Branched Alkanes Linear and branched alkanes may be represented using a: skeletal formula, showing only bonds between carbon atomsshortened structural formula, showing atoms, but no bondsfull structural formula, with all atoms and bonds depicted3-D model, showing atoms and bonds in three dimensions Importance and Uses of Branched Alkanes Alkanes do not readily react because they are saturated hydrocarbons. However, they can be made to react to yield energy or to make useful products. Branched alkanes are of particular importance in the petroleum industry. When provided sufficient activation energy, alkanes react with oxygen to produce carbon dioxide, water, and energy, thus alkanes are valuable fuels.The process of cracking breaks longer chains alkanes into smaller alkanes and alkenes to increase octane number and to make polymers.C4-C6 alkanes may be heated with platinum or aluminum oxide catalysts to cause isomerism to produce branched chain alkanes. This is used to improve octane number.Reforming increases the number of cycloalkanes and benzene ring-containing hydrocarbons to improve octane number.

Sir alex Ferguson case Essay Example | Topics and Well Written Essays - 1000 words

Sir alex Ferguson case - Essay Example Claim that Fergusson prioritized youth player development may not actually define his preference and style of football. With the likes of Ryan Giggs, Paul Scholes and the transfer of Robin Van Persie from Arsenal football club, who according to football profession, was not a young player are some of the indications that Fergusson did not prioritize youth development. In fact youth development should not be linked with his success. Instead, Fergusson preferred quality players and it can therefore be said that he was a manager who fully understood the kind of employees he wanted to keep the fire burning. Nevertheless, Fergusson literally succeeded in the English Premier League by making Manchester United club scoop nineteen league titles and two champions’ league trophies (Elberse & Dye 2-5). Sir Alex Fergusson’s success in the football world can further be measured in terms of the fierce rivals he faced both in the English Premier League and globally. Actually, knocking out clubs like Liverpool football club was not an easy task but through hard work and better strategies, Fergusson managed to topple Liverpool. He was also faced by clubs whose owners had very strong financial muscles such as their neighboring Manchester City and the Russian’s billionaires, London based Chelsea football club. It therefore apparent that Sir Alex Fergusson’s strategies were superior to the finances and some great football styles played by clubs such as Arsenal. Indeed, Fergusson achieved what may not be easy for any manager to achieve in the football world (Elberse & Dye 4-8). Football is really the most popular sport in the world with a good number of players, viewers and heavy financial investment. Additionally, English premier League is regarded superior to other League’s globally because of the ability to contribute a lot of revenue as well as the popular support it enjoys worldwide. English premier League football clubs have a larger worldwid e support thus increasing their global viewers. on the other hand, the Champions League is the most lucrative tournament which, for sure, earned Manchester united $72 million in prize money for being runner up in the 2010-2011 season. Nonetheless it was not easy for Fergusson to successfully and simultaneously win both the Champions League and the English Premier League. Fergusson claims that Pressure and competition placed on him by the local clubs and tribalism to be the main reason behind the inability to win more Champions League trophies as he won English Premier League titles. This may not be genuine reason behind failure to severally capture the most lucrative global football tournament (Elberse & Dye 5-9). Other football clubs like Barcelona and Bayern Munich have managed to reach the peak of the tournament or even win the Champions League titles and their local League trophies easily. It is obvious that the main hindrance was the intense competition from other European club s. Fergusson’s role in Manchester united was wider than any other football manager because his degree of control was wider. He also allowed open communication with the Manchester united director as a way of getting things done smoothly and efficiently. He had his own policies and beliefs that guided his actions and eventually great performance in Manchester United (Elberse & Dye 4-7). Fergusson is an individual who learned from his previous mistakes and improve of his

Persuasion Research Paper Example | Topics and Well Written Essays - 2500 words

Persuasion - Research Paper Example â€Å"Ethical behavior is very significance and important in the society (Johannesen, 2007).† In this paper we will explore the internal and external factors that influence behavior use of deception-Manipulation Theory, Four Factor Model, and Interpersonal Deception Theory. The paper also discusses how visual images, iconic images, music and aroma effect persuasion; Subliminal Messages VS. Supraliminal Messages, Backward Masking, and Neurolinguistic Programming (NLP). Internal and External Factors that Influence Behavior Positive ethical behavior is expected in all careers and engagements in life. In our current society, people do not always do what is expected from them. Sometimes a person is aware that a given action will have negative consequences but still does it. In the society, it is something nice for every person to be responsible and do only what is right. This is the best way to maintain social responsibility and ethical conduct. At the same time, a person should no t be guided to act in a given manner. Such ethical behavior and act should be intrinsic and consistent with human ethical principles, values and moral obligations. The importance of this behavior is that the society will live in harmony and reduce a great deal of problems faced in it (Freeman & Stewart, 2006). With reference to research, it is clear that manipulation theory offers a way of examining at a distinctive part of the interpersonal communication procedure that deals with the manner through which information packages. It is worth noting that manipulation theory is more concerned with the substance of the deceptive messages, the situational substances that bring them about, the extent to which the recognition of that message affects awareness of the deception and the relational effects related with deceptive messages. Ethical behavior determines a person’s action and how it will influence the people around him. For any action, it is necessary to make sure the greatest gain is realized. This can be explained using the utilitarian theory, which is a major ethical theory. According to utilitarianism, an action is viewed ethical if it promotes the greatest or best consequence. The resultant consequence, according to the utilitarian theory, should maximize happiness (Johannesen, 2007). The argument of this ethical theory is that actions are only right if they will promote happiness and wrong if they produce the opposite of happiness. Any form of ethical behavior should therefore be aimed at maximizing happiness. With reference to the Four Factor Model, whenever people are telling lies, there are usually four fundamental mechanisms at work. Such mechanisms include arousal, behavior control, emotion, and thinking. To begin with is arousal. Lying results to arousal and anxiety. This occur either due to disagreement at conflicting behavior and value, or because of the fear of being caught. The second factor is behavior control. Human beings try to have p ower over body language that might give them away. In actual fact this is impossible and leakage frequently takes place, for instance where one is controlling his or her face and his legs give him away. Emotion: Human emotions usually change whenever lying (Freeman & Stewart, 2006). Thinking: to lie, we frequently have to think harder in order to guarantee coherence in our arguments. Research records that interpersonal deception theory explains the way through which people cope

Law an Offer and Acceptance Essay Example | Topics and Well Written Essays - 1500 words

Law an Offer and Acceptance - Essay Example An offer can be defined as an expression of a willing to contract, on particular terms which becomes binding, upon the acceptance of the one to whom it was directed to. The expression of a contract generally means the form in which the contract is embodied in. It could be expressed in a letter, in the traditional sense, an email, fax and construed from the conduct of the offeror communicating the main grounds for the contract terms. The case of Smith v Hughes defines what entails intention to create legally binding agreement entails. It was held that the court objectively deduct an intention, not on the basis of the offeror’s intention per se but on the premise of what a reasonable man would construe as intention. However, beyond the classic definition of an offer being a bilateral expression of willingness to contract; there are instances in which the court has interpreted unilateral contract and held that they were legally binding. An excellent example emerges from the case of Calil v Carbolic Smoke Ball Company. In this case, the smoke ball company, made an advertisement in the newspaper stating that it will give a reward of 100 pounds for anybody who used the smoke ball as prescribed and still gets influenza, a cold or a related disease. Calil on seeing the advertisement bought the smoke ball used it as per the instructions and, when she contracted the influenza she proceeded with the lawsuit. Lord Lindley, held that it emerged from the conduct of the offeror a waiver of the offeree duty to notify them acceptance from the nature of the public advertisement; and thus an acceptance by Calil was held to be valid thus they were instructed to pay the price of 100 pounds. There are cases in which an offer may be confused with an invitation to treat. An invitation to treat is not an offer, but an invitation of a negotiation of terms of a contract. This was illustrated in the case of Harley v Facey where the owner of some property had indicated that he was w illing to sell his property at a certain rate. The person to whom this was directed took it as an offer and moved to court to enforce the said offer. It was held that it was an invitation to treat thus, made with the intention of receiving offers. There are four kinds of invitation to treat in common law in common law. One is an auction, where a bid is held to be an offer for the auctioneer to either accept or reject. In Payne v Cave, D made the highest bid for an item in an auction but withdrew the bid before the fall of the hammer. It was held that the bid was an offer and thus revocable before acceptance. Acceptance occurs at the fall of the hammer. An advertisement is also an invitation to treat and not an offer. In the case of Partridge v Crittenden, D made an advertisement for the sale of a protected species of birds and was sued under respective Act. It was held that the advertisement was a mere invitation to treat and not an offer. Exhibition for goods for sale like it is do ne in supermarkets constitute an invitation for customers to make offers and are not offers in itself. In the case of Fisher v Bell where it was held, displaying goods with the price on them was an invitation to treat and receive offers which the shopkeeper could either accept or reject. An invitation for tenders is the last example of invitations to treat and not an offer. Response to the tenders is the offers that the person who advertised the tenders can either accept or

NFL Personnel Hiring for market plan Essay Example | Topics and Well Written Essays - 1500 words

NFL Personnel Hiring for market plan - Essay Example This was done in order to guarantee a large audience-not everyone can make it to the stadiums. Some of the television stations include NFL network, ESPN, FOX and NBC. Some of the radio stations owned by the NFL include Westwood one, Sports USA and the United Stations Radio Networks. (Green Berg, 2007) Players in the NFL all belong to a union called the NFLPA. This union has the mandate to negotiate contracts for players. The players are governed by a contract called the CBA. Players are only allowed to play for teams that endorse them. Other older players are allowed to negotiate their contracts with other teams after a certain number of years. The contract signed by the players and the NFL has regulations regarding salary packages and it stipulates what are the minimum and maximum amounts to be paid to players. The NFL has a peculiar way of picking out its players. It normally uses the NFL draft. Teams usually endorse a player and earn the right to keep him. However, trades can be made for players from other teams upon agreement by the first team that chose him. The NFL requires that the Franchise owners pay an amount of fifty dollars when they appear for drafting. This is normally done annually in the month of April. There are specific amounts given to those who get first, second and third place. Franchise owners are allowed to make moves as soon as the draft is complete. They also have to pay a small amount for every interchange made in order to finance an award at the season's end. (Sands, 2002) Once these players have been selected by their teams, they are allowed to play in any position within the team that chose them. Franchise owners are supposed to choose players from six categories that include quarterbacks, kickers, defenders, running backs, tight ends and wide receivers. Each category has a maximum number allowed by the league. Franchise owners should submit in names of players that will participate in the expected week's game from all the categories listed above. Trade offs between franchise-owners for players are permitted only after notifying the commissioner. In addition, there must both agree to the terms of the deal. This can only be done within a stipulated amount of time. Franchise owners must make sure they do not exceed the deadline. Waivers can be done all through the season after payment of a specified fee. In addition, there must be a notification to the franchise owners that a player has been waived. (Ed Gruver, 1997) The League can overrule a player trade off that has been done unfairly. This could be possible when a team has taken a player in order to weaken a certain team and to strengthen itself unfairly. Franchise owners can also conduct a vote that overrules decisions by the commissioner. Names chosen by Franchise owners must be free of offence. This is especially in regard to players' wives. The commissioner can also reject names that are deregulatory or stupid. As franchise owners enter the league, they ought to submit their logos. Lastly, there is a provision for a modification of the rules after the end of the season. Here, there must be a unanimous vote by franchise owners. How the last Franchise expansion was done There are a number of franchise expansions that have characterized the National Football League. A good example is the Houston Texans Team. This expansion was done in the year 1997 by franchise owner Bob McNair. He wanted to bring

The trail of Tears Essay Example | Topics and Well Written Essays - 500 words

The trail of Tears - Essay Example Over 15,000 of our members, led by Chief John Ross, have signed a petition in protest of this false treaty. Despite this, the United States Supreme Court dismissed our concerns and this year ratified the treaty. We have now been given two years to migrate voluntarily to the west, away from our own country, to unfamiliar territory beyond the Mississippi. Forcible removal has been threatened if we do not leave on our own. Citizens of the United States, we do not wish to leave our lands, nor should we be forced to do so. Such a move would not be in our best interests; indeed it would be fatal to us as a nation. Firstly, it is an area completely unknown to us, and in addition is already occupied by other Indian nations who would not take kindly to encroachers upon their territory. We would be forced into close proximity with neighbors with whom we do not share a language or customs. The territory is also inadequately supplied with wood and water, making it much harder for us to survive. We appeal to the sense of fairness in the citizens of the United States, because previous to the false treaty, all agreements upheld our sovereign rights. Those treaties explicitly acknowledged us to be a separate people, in a separate territory comprising our own country, and were supposed to be secured and protected by your government. In the 1832 Supreme Court case Worcester v. Georgia, the majority opinion written by Chief Justice John Marshall rendered a judgment firmly upholding our rights. It stated, in part, that Indian nations should be regarded as distinct political communities, with their own territorial boundaries in which exclusive authority is exercised, as guaranteed by the United States. Although the case specifically addressed the legal question of whether the State of Georgia could forcibly seize any person residing within our nation with our permission, it forthrightly addresses our territorial and sovereign rights.

Global warming Research Paper Example | Topics and Well Written Essays - 250 words

Global warming - Research Paper Example What makes their excess in the atmosphere particularly dangerous is their function. They serve as a blanket for the sun rays after they reach the Earth, so that they can not radiate back to the space (Kayne). The tremendous energy stored in the sun rays thus adds to the heat of the environment, and the temperature of the Earth rises in general. The rising temperature has many repercussions. As the temperature is going up, glaciers are melting away, thus adding to the sea water. There has been a considerable rise in the sea level over the past few centuries. The excess water floods out of the sea and causes damage to life and property on Earth. Every year, several tsunamis happen in different parts of the world. Much of the natural disasters can be attributed to the global warming. Moreover, global warming is depriving the polar bears of their habitat. As glaciers melt away, polar bears find it difficult to

The Drama GCSE Course Essay Example for Free

The Drama GCSE Course Essay During the summer term of 2003 I have been working on an improvised piece of drama for option 3 of the drama GCSE course. The theme of our piece is fame. Our improvisation is about a young man called Jack who has the misfortune to become famous at first this is his dream come true but as the story unfolds he becomes more miserable and becomes addicted to drugs. The opening scene is where everyone who has had something to do with his death is gathered around him in his coffin at his funeral. Caudilia Smith throughout the funeral stays totally emotionless and does not shed a tear for her dead husband. Then it switches to Jack in bed being woken by his drug dealer, she barges in and starts to threaten Jack and he tells her he can get the money tomorrow and she agrees and tells him he will be dead if he doesnt. then we move further back and go to the high street where he first becomes famous. A news reporter comes to the agent who is sat at one of the cafes on the road where she is accosted by a journalist and is asked to comment on her upcoming blockbuster this is the scene where we find out that the agent is looking for a real life hero. Then Bernard moves past the journalist who has to move to block the agents way whilst Jack and Bernard are talking which is significant because Bernard starts to walk across the road but a car is coming and he does not see this because he is fixated on Jack but luckily a passer-by comes to the rescue and saves him but everyone thinks it was Jack who has saved him and because of this Jack becomes skyrocketed into fame which gets him a wife and helps feed his habit. But as he goes on his head gets bigger so he cant see the cracks that are forming below him. Caudilia finds out about his habit from a phone call that she listened in and she informs the papers and then because his agent finds out about this he gets sacked and then his wife leaves him and he has no-one left and then he kills himself. And then we all put him in his coffin, which is significant because it was our fault that he died so we are putting him in his coffin. When Maria Marten was set it was normal to see Gypsies and for the social classes to affect relationships then. And also the difference in currency then because it is not Guineas any more. The language is much different compared to the improvisation that we are doing now because we use much shorter sentences and frequent swearing but at the time of the script it would be considered very rude to swear but now its seems like a second language (not to me of course) to us. Also even the William confessed his love for Maria he hid it from the public and when he was caught with Dora and she asked who she was William just fobbed Dora off and said that she was just a peasant and he probably would not be caught dead with a girl like Maria. At the time of Maria Marten people believed Gypsies and took head of what they said but whereas now no one believed them, also people wouldnt be allowed to speak to other people in a higher social class than themselves. People behaved a lot different in the Victorian times because they had to be seen as properly behaved they couldnt be seen with people that were in a lower class than they were and this is where snobbery comes into it. And in the Victorian times people lived dull lives and didnt have much to do so going out to see a melodrama was like going to an Eminem concert for use it was that exciting! A melodrama in the Victorian days is the equivalent of going to the cinema and watching a movie. In our piece there are different types of cherecters in there there is Caudillia she is the gold digging bitchy type and then there is Bernard who is a nice person and is always good natured until he finds out jack has not been entirely honest with him. Then ther is the scheming journalist and then there is the larger than life I dont have any time for you agent. We chose this type of style of drama because it suted what we wanted serious yet funny and I feel this suted what we wanted exactly because with the amount of people there is there is enough room for both types of acting. We have learnt of the changes in the time affect the type of thinks that are funny now becayse they would not be funny then they probably would be improper. The fact that the script ended in tragedy gave us an incentive to head in the direction of tragedy.

Protective Effects Of Fluoride Toothpastes Health And Social Care Essay

Protective Effects Of Fluoride Toothpastes Health And Social Care Essay The main aim of this report is to discuss the evidence for the protective effects of fluoride toothpastes and varnishes. In addition, I will discuss their application and mode of action. To begin with, I will give a brief history of fluoride and how it fits into the reversal of tooth decay. I will discuss fluoride varnishes namely Duraphat, Fluor Protector and Duraflor and their effect on the DMF Index and their roles in school based prevention programmes. There are other varnishes such as Lawefluor and Bifluorid but these are less commonly used and therefore, I will not be discussing them. After discussing fluoride varnishes, I will consider fluoride toothpastes. I will give a description on the composition of a typical toothpaste and the effect of fluoride toothpastes on the DMF Index. In addition, I will discuss the effects of high fluoride concentration toothpastes. Finally, I will compare both toothpastes and varnishes. Contents Pages Summary Contents Introduction Deposition of fluoride in enamel What is tooth decay? Fluoride: Mode of Action Who is at risk of decay?

Use of fluoride toothpastes in clinical trials High Fluoride toothpastes The use of fluoride toothpastes in advanced enamel lesions Comparison of Toothpastes and Varnishes Conclusion Acknowledgements Word Count References Introduction I have decided to carry out this report on fluoride as I realise the importance of its role in the prevention of tooth decay (dental caries). Fluoride is a negative ion of the element fluorine and is found naturally in water, foods, soil, and minerals such as fluorite (calcium fluoride) and fluorapatite. Fluoride can also be synthesised in laboratories where it can be added to oral hygiene products and to water. Fluoride utilisation has occurred in two phases: before water fluoridation in the 1950s and after the widespread use of fluoridated dentifrices in the 1980s (Cury, Tenuta 2008) when less than 10% of toothpastes contained fluoride compared with 96% at present. Fluoride is most effective post-eruptively (Oganessian, Lencova Broukal 2007) where the effects are generally topical and therefore, it is important for a constant fluoride concentration to be maintained in the oral environment. Topically applied fluoride provides high concentrations of fluoride to surfaces of the denti tion. This provides a local protective effect and prevents ingestion of large amounts of fluoride. (Marinho et al. 2004) Deposition of fluoride in enamel During apatite crystal formation, low concentrations of fluoride are incorporated into the tooth structure. This leads to supersaturation with respect to fluoridated hydroxyapatite: {{66 ten Cate,J.M. 2008) Ca10(PO4)6(OH)2+ F-= Ca10(PO4)6(F)2 + 2OH- (Fluorapatite) After calcification is complete and prior to eruption, additional fluoride is taken up by the surface enamel. After eruption, the enamel continues to take up fluoride from its oral environment leading to its profound topical effects (Kidd 2005). What is tooth decay? It is important to consider the causes of tooth decay and how fluoride can be used to reverse the carious process. Dental Caries is a multifactorial disease caused by the action of acidogenic and aciduric bacteria (Streptococcus Mutans and Lactobacilli ({{32 Featherstone,J.D. 2008}}) on fermentable carbohydrates such as sucrose. Salivary glycoproteins form a pellicle on the tooth to which these bacteria attach to forming a pathogenic biofilm and over time, acid demineralisation and proteolytic destruction of the organic component of the enamel and dentine takes place (Young, Kutsch Whitehouse 2009). Dental Caries can be classified in several ways According to location-Caries may be restricted to pits and fissures but may also progress to expose the pulp. Restorative status of the tooth- Primary caries occurs on previously unrestored teeth whereas secondary caries occurs at margins of restorations {{52 Kidd,Edwina A.M. 2005}}. Secondary caries is caused by local factors that are involved in the formation of cariogenic plaque. Most secondary carious lesions develop at the gingival margins of restorations primarily in areas of stagnation areas (Mjà ¶r, 1998). Large gaps between the restoration and the wall of the cavity preparation can create an environment that favours secondary caries formation (Mjà ¶r, 1998). Secondary caries is also known as recurrent caries. Caries can be arrested whereby a lesion which was previously active has now stopped progressing. Fluoride: Mode of Action Fig 1: Demineralisation Process and the role of fluoride (Cury, Tenuta 2008) Figure one shows how sugars such as sucrose, glucose and fructose are converted to acids in the plaque biofilm. When the pH decreases below 5.5 (critical pH of enamel), the saliva is no longer supersaturated with calcium and phosphate. Therefore, demineralisation occurs. However, in the presence of fluoride and if the pH is higher than 4.5, hydroxyapatite is converted to fluorapatite which has a lower solubility. As a result, net demineralization is reduced and the dental hard tissues are more acid resistant. Tenuta and colleagues calculated that fluorapatite would not dissolve until the pH dropped below approximately 4.4. However, researchers have found that the effect of fluoride is not only due to the decreased solubility but also due to the effect of fluoride on the rates of demineralisation and remineralisation (Stoodley et al. 2008). In order to enter bacteria, fluoride must be combined with a hydrogen ion forming hydrogen fluoride (HF), which readily diffuses into the cell. Once inside the bacterial cell, the HF dissociates into fluoride and hydrogen ions. The fluoride inhibits intracellular bacterial enzymes such as enolase. As a result, less phosphoenolpyruvate and lactate are formed. The reduced lactate formation limits the ability of bacteria to cause caries. Similarly, the uptake of glucose is also reduced by fluoride {{63 Featherstone,J.D. September 2004}}. The fluoride concentration in saliva increases after brushing with a fluoride toothpaste. After three minutes, the concentration is 100 times greater than the baseline value (normally 0.03ppm or 1.6umol/l) {{65 Murray, J.J 1991}}. Two hours later, the concentration returns to normal. It is important to avoid rinsing out the mouth as the most profound effects of fluoride are within two hours of brushing. Fluoride is spread throughout the oral cavity and is stored in compartments on the tooth surface and the remaining pellicle (Cury, Tenuta 2008). Calcium Fluoride globules are formed and are reservoirs of fluoride, releasing it as the pH falls, thereby, reducing time spent in the demineralisation phase. The main effects of fluoride can be attributed to the maintenance of constant fluoride levels in the biofilm. Overall, fluoride has multiple ways of reducing caries. It is believed that the most important of these methods is the remineralisation concept {{40 Oganessian,E. 2007}}, which requires a constant flow of fluoride. Bacterial enzyme inhibition plays a supplementary role when the concentration of fluoride is high which is achieved by topical fluoride applications and toothpastes (Murray, Rugg-Gunn Jenkins 1991). Who is at risk of decay? There are certain groups in the population who are at risk of decay and therefore, would benefit from the use of fluoridated dentifrices. These include patients with: Xerostomia, which may have resulted from the radiotherapy to the head or neck leading to salivary gland exposure. This leads to a decrease in both the resting and stimulated salivary flow rates. Xerostomia is defined as the complete absence of saliva or hyposalivation. Hyposalivation leads to decreased levels of calcium, phosphate and hydrogen bicarbonate ions. As a result, there is a longer demineralisation phase Sjà ¶grens syndrome- this is clinically defined as at least two of kerataoconjuctivitis sicca, Xerostomia(dry mouth) and rheumatoid arthritis or another connective tissue disease {{62 Newbrun,E. 1996}} A high incidence of caries in their primary dentition Hypersensitivity Root caries Removable orthodontic appliances and partial dentures A poor diet and those who regularly snack on fermentable carbohydrates {{37 Evans,R.W. 2008}}. However, this risk has decreased due to better plaque control and increased fluoride exposure. Multiple restorations suggesting a high prevalence of caries Optimum fluoride concentration required for remineralisation Bjarnason and Finnbogason (1991) found that fluoride levels in dentifrices had no effect on the progression of enamel lesions detected radiographically. However, a higher fluoride concentration (1000ppm F-) led to reduction in caries initiation compared to a dentifrice with a lower fluoride concentration (250ppm F-) {{69 Bjarnason, S. 1991}}. It is ultimately difficult to decide the optimum fluoride concentration required for remineralisation as different areas of the mouth are more at risk of caries due to unique ecological factors. However, it was thought that lesion progression in enamel was slowed down only in patients with low caries activity whereas patients with high caries activity still experienced rapid progression (Hellwig, Lussi 2001). DMF Index The DMF index is a measure of caries activity in a population and changes in the DMF index can be used to highlight the protective effects of the fluoride toothpastes and varnishes (Kidd 2005). D: decayed teeth with untreated carious lesions M: missing teeth (extracted teeth) F: filled teeth DMFT denotes decayed, missing and filled teeth DMFS denotes decayed, missing and filled surfaces in permanent teeth and therefore, the number of surfaces attacked on each tooth are accounted for. There are similar indices for deciduous tooth, which are the defs and deft scores. The e represents extracted teeth to differentiate(Johansen et al. 1987) between natural loss of teeth through exfoliation. Burt in 1998 suggested that greater emphasis has to be placed on the assessment and early diagnosis of caries {{77 Burt, B.A. 1998}}. This has been backed up by cohort studies {{83 Johansen, E. 1987}} (Axelsson, Lindhe Nystrom 1991), which found that the use of preventive strategies (fluoride application) resulted in a substantial reduction in lesion development and progression. Fluoride varnishes What is fluoride varnish? Fluoride varnish was first developed in New York in 1968 by Heuser and Schmidt in the form of sodium fluoride and was marketed under the name Duraphat. The Duraphat varnish contains 22,600 parts per million of fluoride (ppm Fˆ°) as shown in figure 2. In the 1970s, there was a switch from sodium fluoride to difluorsilane which was marketed under the name Fluor Protector (7000ppm Fˆ°) in Germany {{42 Azarpazhooh,A. 2008}}. Fluoride Varnish Type of fluoride Fluoride Concentration(ppm) Fluoride Concentration(%) Duraphat Sodium Fluoride 22,600 2.26 Duraflor Sodium Fluoride 22,600 2.26 Fluor protector Difluorsilane 7,000 0.70 Fig 2: The table above shows the fluoride varnishes that are most commonly used. Other types of fluoride varnishes include: Fluoride Varnish Type of fluoride Fluoride Concentration(ppm) Fluoride Concentration (%) Lawefluor Sodium Fluoride 22,600 2.2 Bifluorid Sodium and Calcium Fluoride 56,300 5.6 Fig 3: The table above shows other fluoride varnishes which are available but are less commonly used {{24 Davies,G.M. 2008}}. Most fluoride varnishes contain fluoride in an alcoholic solution of natural tree resin. The main advantage of the varnish is that the resin base is very adherent to the tooth prolonging contact time between the fluoride and enamel {{26 Miller,E.K. et al 2008}}. Varnishes are easy to apply and relatively safe regardless of the high fluoride concentration as the amount of varnish applied to one child is only 0.5 ml on average (Ripa 1990; Petersson 1993). Varnishes are slow-releasing reservoirs of fluoride preventing immediate release of fluoride after application (Ogaard 1994). As a result, they are most effective at protecting against primary caries. The food and drug administration centre in America has not yet accepted fluoride varnish as an anti-caries agent but considered it as a liner/desensitising agent (Mason 2005). There is some debate as to the amount of fluoride taken up by the tooth surfaces. It was found that approximately half of the fluoride taken up by sound surfaces from Fluor Protector varnish was lost after 6 months suggesting that the large amount of fluoride taken up after one week does not bind permanently to enamel and that the effects of fluoride are more short term. There has also been a debate over whether fluoride varnish should be applied to wet or dry surfaces. Koch et al found that the fluoride uptake was much greater when the varnish was applied to dry tooth surfaces (Koch, Hakeberg Petersson 1988). Fluoride varnishes can be applied professionally up to two to four times a year. Marinho et al in 2002 investigated the effectiveness of fluoride varnish in preventing dental caries in children compared to a placebo or no treatment. Over 2700 systemically healthy children aged 16 or less received fluoride varnish containing 22,600ppm sodium fluoride. There was a large caries inhibiting effect on both permanent and deciduous dentition. However, the confidence intervals were relatively wide and the variation among the results was substantial. The success of the treatment may have been over estimated, as the results of the few trials may not have been representative. As a result, it is important to carry out more trials before a definite statement can be made of the effects of the fluoride varnish (Marinho 2002). In addition, more information is required on the scale of the fluoride effect and the adverse effects of fluoride. Effect on the DMFT/dmft Primary Dentition There was a 33% decrease in the decayed, missing and filled surfaces (Marinho 2002). A two year randomised clinical trial carried out on children with a mean age of 1.8 years, found that the application of fluoride varnish once, twice and three times a year reduced the mean dmfs by 53%, 58% and 93% respectively {{67 Davies,G.M. 2009}}. This highlights the importance of frequent varnish application. (Petersson, Twetman Pakhomov 1998)Petersson et al. in 1998 found a 19% and 25% reduction in the increment of approximal caries in children with a moderate or high caries risk respectively. This shows that children with a high caries risk benefit the most from the application of fluoride varnishes (Zimmer 2001). Ages 0-3 Weintraub and colleagues carried out a two year randomised controlled trial on 376 children aged between 6-44 months (Weintraub et al. 2006). The children were split into three groups: Those who received counselling Those who received counselling and the annual application of Duraphat Those who received counselling and the twice yearly application at six monthly intervals The number of lesions only increased in children who received counselling alone highlighting the protective effects of the varnish. Those children who received no varnish application were twice as likely of developing decay as those who received the annual application of fluoride. As the frequency of fluoride varnish application increased, the number of carious lesions decreased. One drawback of this trial was that simultaneous counselling and varnish application led to some ambiguity as to whether the effects were due to varnish application or counselling although fluoride application was seen to play a key role. Ages 3-6 According to the Cochrane Review, there was an overall 38% reduction in the DMFS/dmfs (Marinho 2002). A two year randomised study of 1,275 children in Canada aged between 6 months and 5 years found that twice-yearly application of Durafluor led to an 18.3% reduction in the dmfs increment (Lawrence et al. 2006). Mixed dentition There was on average a 46% decrease in dmfs. The fluoride varnish was an effective preventive measure for partially erupted permanent molars. Equally, patients who are insufficiently co-operative benefit from fluoride varnish application (Marinho 2002). Permanent dentition A randomised clinical trial used to examine the impact of fluoride varnish on the incidence of approximal caries, detected radiographically in 13 year olds over a three year period, found that the varnish applied monthly and twice a year reduced caries by 76% and 57% respectively again highlighting the importance of frequent fluoride application{{67 Davies,G.M. 2009}}. The caries reduction in permanent teeth shown in the Cochrane review of trials was similar to that achieved in a metaanalysis carried out by Helfenstein in 1994 when Duraphat was applied 2 times a year in children aged 9-15 years (Helfenstein, Steiner 1994). There was a 38% reduction in the caries. It is likely that most of the participants benefited from the use of a fluoridated dentifrice as the majority of the studies were carried out in Scandinavian countries between 1973 and 1987. However, as both the Cochrane review and the Helfenstien study were carried out involving a different selection criteria, it is debatab le as to whether the results from both these trials can be compared. In conclusion, application of fluoride varnish two to four times a year on both permanent and deciduous teeth is associated with a reduction in the caries increment (Marinho 2002). The effect of fluoride varnish according to different caries risks Mà ¶berg Skold carried out a trial which involved the application of fluoride varnish to approximal caries in adolescents living in different caries risk areas. The trial involved 758 students aged between 13 to16 years old. The large sample size meant that the results of this study were representative. This is because as the sample size increases, the variability of the results decreases. This means that the results have a greater statistical power and smaller confidence intervals. Fig 4: (Azarpazhooh, Main 2008) The figure above shows the groups which were chosen according to their caries risk and whether they had any fluoride in their tap water. Duraphat was applied to the approximal surfaces from the distal surface of the canines to the mesial surface of the second molars. Each group had different intervals of application shown in the figure below: Group No. of participants Frequency of Duraphat application One 190 Twice yearly in six-monthly intervals ( 6 times in 3 years) Two 186 Three times a year with a one week period each year(9 times in 3 years) Three 201 Eight times a year during school terms with one month intervals ( 24 times in 3 years) Four(Control) 181 No application Fig 5: (Azarpazhooh, Main 2008) The frequency of Duraphat application The results from this trial show that the biggest difference was between group one and the control group in high caries risk area (Gà ¶teborg). However, there was no significant difference between the groups regarding filled approximal lesions and approximal enamel lesions. There was a greater incidence of caries in the control group in comparison to the fluoride varnish groups in all risk areas highlighting the protective effects of the fluoride varnish (Mà ¶berg Skold et al. 2005). Overall, it was found that the school based monthly application of fluoride varnish is the best method of preventing approximal caries in areas of medium and high caries risk (Mà ¶berg Skold et al. 2005). School based prevention programmes A cluster randomised trial was carried out by M.C Hardman and colleagues involving 2,091 school children living in a non-fluoridated area. One group of students (1,025 students) received the twice-yearly application of Colgate Duraphat varnish whilst the other group (1,066 students) served as a control. This study found that the twice-yearly application of fluoride varnish did not lead to a reduction in caries in children living in the community {{43 Hardman,M.C. 2007}}. This is contrary to what was found by Marinho and colleagues. They found that the biannual application of Duraphat in a school-based programme provided a caries inhibition of 38% in children aged 9-15 years (Marinho 2002). The study carried out by M.C Hardman and colleagues did not prove to be conclusive as the level of consent in the community was low. Approximately 110 students were lost during the study. The control group had lower caries levels than anticipated and therefore, it was difficult to tell the true eff ect of fluoride. In addition, the application of varnish was carried out under sub-optimal conditions (teeth could not be cleaned prior to application and the consumption of food and drink after application could not be controlled), which could have resulted in less profound effects. In conclusion, it was found that this type of fluoride varnish intervention is not effective in the prevention of caries in the public {{43 Hardman,M.C. 2007}}. A similar study was carried in a small town located in the American Southwest on children attending a head start nursery using Duraflor as the varnish of choice. The trial began in the head start class of 2002. Duraflor was applied during well child visits every 9, 12, 15, 18, 24 and 30 months. The class of 2003 had no fluoride application and therefore, served as the control. The mean age was 4.40 years and approximately 168 males and 189 females took part. The results showed that children who received no treatment had a mean dmfs of 23.6 with a 95% confidence interval. Those children who received 1-3 treatments had a similar dmfs to those with no treatment. Only those children who had 4 to 5 treatments showed a reduction in dmfs again suggesting the importance of frequent application. However, this study was an observational study not a randomised study and therefore, the reliability of the results can be questioned. In addition, no attempt was made to determine whether the childre n who received four or more applications of fluoride varnish differed from the other children in terms of diet and oral hygiene history {{58 Holve,S. 2008}}.. The use of fluoride varnish in inhibiting secondary carious lesions As mentioned earlier, secondary caries forms at the margins of restorations. Larger amounts of fluoride varnish may be trapped in the gap formed between the restoration and the cavity wall. This may serve as a slow releasing reservoir of fluoride, which could also provide a physical barrier against wall dissolution. In a study carried out by M. Fontana in 1996, two experiments were carried out. Experiment one involved the application of Duraflor. Experiment two involved the application of Duraphat a year after the application of Duraflor. The effects of fluoride varnish on secondary caries remineralisation and lesion progression were measured. The varnish was applied to dry tooth surfaces and rinsing after fluoride application was prevented to enhance the remineralisation potential. The varnish was applied for 24 hours to prolong the contact time between the varnish and the tooth surface. The results from these two experiments showed that fluoride application slowed down lesion progression around both amalgam and composite restorations {{48 Fontana, M. 2002}}. The placebo varnish slowed down lesion progression to a lesser extent than the fluoride varnish suggesting that the effects may not only be attributed to the fluoride in the varnish. These results matched those in a previous study carried out by Hellwig et al. in 1993. They examined the effect of Duraphat varnish on artificially created primary carious lesions and found that fluoride varnish led to remineralisation in the outer layers of enamel {{78 Hellwig, E.K. 1993}}. This slowed down lesion progression. Seppa suggested in 1988 that the benefits of fluoride varnish were attributed to their ability to enhance remineralisation of primary caries rather than their ability to increase the fluoride content of the tooth surface. This is contrary to what was previously thought that the effects of topical fluoride were due to their ability to maintain high levels of fluoride on the surface of the tooth. Seppa also found that the efficacy of the fluoride varnishes was dependent on the number of applications rather than the concentration of fluoride {{79 Seppà ¤, L. 1988}}. This backs up the results found by Marinho et al that showed that the more frequent the applicati on, the lower the incidence of new caries or the greater the decrease in mean dmfs/DMFS. Fluoride toothpaste What is fluoride toothpaste? Fluoride toothpaste is the most widely used method of fluoride application in the population due to its ease of use. Fluoride toothpastes can be incorporated into community and school based prevention programmes. Most oral health care workers recommend brushing twice a day, once just before going to bed, as this is when saliva flow is at its lowest and once at another time of day{{68 Davies,R.M. 2003}}. They recommend spitting out the toothpaste after use rather than rinsing as this dilutes the fluoride concentration in the oral cavity as previously mentioned. The widespread use of fluoride toothpastes had made it more difficult to distinguish whether a reduction in caries is due to mechanical plaque removal or due to the incorporation of fluoride. Before the widespread use of fluoride toothpastes, the importance of fluoride was illustrated in a three-year study. This study involved two groups of children aged 9 to 11 years who had benefited from supervised brushing either with or without fluoride toothpaste. Both groups showed a reduction in plaque and gingivitis but a significant reduction in caries was only seen in the group which used fluoridated toothpastes (Davies et al. 2003). A typical toothpaste contains abrasives such as calcium carbonates, which help to remove surface debris, and stains on the tooth surface. Most toothpastes contain fluoride (added to toothpastes in the 1970s) to make the tooth more resistant to acid attack and is one of the most recognised agents in toothpastes. Stannous fluoride (also known as tin fluoride) was the first fluoride to be used due to its compatibility with the abrasive, calcium phosphate. Sodium fluoride could not be used at first as the calcium in the abrasive renders it ineffective and therefore, is not compatible. Sodium Monofluorophosphate was next used as it was compatible with the abrasives used with it. Sodium Fluoride could only be used when hydrated silica and sodium bicarbonate became the abrasive of choice. Studies have shown that the sodium bicarbonate-sodium fluoride combination lead to a caries reduction of one surface per child over two years (Murray, Rugg-Gunn Jenkins 1991). Fluorides have been shown to work better in combination with detergents such as sodium lauryl sulphates, which aid the remineralisation process and create foaming whilst brushing. Toothpastes contain humectants such as glycerol, which prevent the loss of water in the toothpaste. To provide taste, saccharin and other sweeteners are added. To stabilise the toothpaste, thickening agents such as seaweed colloids are included to ensure that the toothpaste stays on the toothbrush when it is applied. The use of fluoride toothpastes in clinical trials The Cochrane review of trials found that children who used fluoridated toothpaste had fewer decayed,missing and filled permanent teeth after three years. Brushing twice a day helps to increase the benefit of fluoride (Marinho et al. 2003 England). Researchers believe that the effects of fluoridated toothpastes are underestimated in two to three year trials due to the life long used of fluoride. They also found that the use of fluoride toothpastes in areas of fluoridated water increased the protective effects. The normal concentration of fluoride in toothpastes is between 1000 and 1100 parts per million (ppm Fˆ°). Toothpastes with higher fluoride concentrations (1500ppm) and lower fluoride concentrations (500ppm) are available in many countries. Toothpastes containing higher fluoride concentrations offer greater protection against caries (Stephen 1988; OMullane 1997). Since the 1940s, more than a 100 clinical trials have been carried out and by the late 1970s, the protective effects of fluoride toothpastes were greatly accepted. As a result, many clinical trials could not have a control, as the removal of fluoride toothpaste for the trial was considered unethical. Therefore, the effectiveness of different concentrations of fluoride toothpastes have not been investigated extensively in placebo-controlled trails. The guidelines of caries trials have since been changed in order to combat this problem, by increasing the sample size so that the measurement error could be reduced (Marinho et al. 2003 England). Children or adolescents aged sixteen or less were chosen to take part in the study carried out by Marinho et al. To assess the effect of the fluoride toothpaste, the caries increment was measured as a change in the value of the DMFS Index, in all permanent teeth erupted at the start and erupting over the course of the study. Evidence from this study suggested that the use of fluoride toothpastes leads to a 24% decrease in dmfs. The confidence intervals for this reduction were 21-28%. This means that 1.6 children need to brush with fluoride toothpaste to prevent one decayed, missing or filled tooth surface in a population where the caries increment is 2.6 DMFS per year. Where the caries increment was lower (1.1 DMFS per year), 3.7 children needed to use a fluoride toothpaste in order to avoid one decayed, missing or filled tooth surface(Marinho et al. 2003 England). There was also a substantial reduction in caries increment (37%) of deciduous teeth in a trial carried out on 2008 children aged 6 to 9 years. Another aim of the Cochrane review (Marinho et al. 2003 England) was to establish whether there was any relationship between the caries-preventive effects of fluoride toothpaste and the initial level of caries, previous exposure to fluoride and the frequency of fluoride toothpaste use on the prevented fraction. The prevented fraction (PF) is the proportion of disease occurrence in a population averted due to a protective risk factor or public health intervention (Gargiullo, Rothenberg Wilson 1995). The prevented fraction was measured as the diffe
