Accutane for Acne: An Analysis

Accutane for Acne: An Analysis Before the iron curtain fell any Information about acne was rare. But with growing advances in dermatology and medicine now understanding the cause of acne and its accurate treatment is available worldwide. Acne is one of the most common skin conditions in the world. Although it’s common but accurate information about acne can be scare. This makes it difficult to get clearer skin. Therefore the information in this document can help you understand acne and how to treat/ prevent it successfully. [1]Overview of acne: Acne, or acne vulgaris, is askinproblem that starts when oil and dead skin cells clog up your pores. Some people call it blackheads, blemishes, whiteheads, pimples, or zits. When you have just a few red spots, or pimples, you have a mild form of acne. Severe acne can mean hundreds of pimples that can cover the face, neck, chest, and back. Or it can be bigger, solid, red lumps that are painful (cysts). Acne is very common amongteens. It usually gets better after the teen years. Some women who never had acne growing up will have it as an adult, often right before their menstrual periods. How you feel about your acne may not be related to how bad it is. Some people who have severe acne are not bothered by it. Others are embarrassed or upset even though they have only a few pimples. Acne starts whenoil and dead skin cells clog the skins pores. If germs get into the pores, the result can be swelling, redness, and pus. Causes of Acne Acne can be caused or exacerbated by a number of different things, including: Changes in hormone levels (such as during puberty or menstruation) Cosmetics or hair or skin products Having a family history of acne Some medications Something rubbing on the skin (like a hat or helmet) Vigorous scrubbing of the skin Stress For most people, acne starts during the teen years. This is because hormone changes make the skin oilier afterpubertystarts. Using oil-based skin products or cosmetics can make acne worse. Use skin products that dont clog your pores. They will say noncomedogenic on the label. Acne can run in families. If one of your parents had severe acne, you are more likely to have it. Symptoms of acne : Acne commonly appears on the face and shoulders. It may also occur on the trunk, arms, legs, and buttocks. Other symptoms include: Crusting of skin bumps Cysts Papules (small red bumps) Pustules Redness around the skin eruptions Scarring of the skin Whiteheads Blackheads The good news is that there are many good treatments that can help you get acne under control. What is Accutane[2] [3]Accutane’s chemical composition resembles that of retinoic acid, a compound derived from Vitamin A. The primary application for Accutane is for nodular acne in patients that do not respond to topical applications (such as benzoyl peroxide) and standard antibiotic treatments.it is administered orally in pill form. It reduces the amount of oil released by oil glands in your skin, and helps your skin renew itself more quickly. People with severe cases of nodular acne can display red, tender and swollen bumps under the skin. These bumps can have a diameter of a quarter-inch or larger. Left untreated, these bumps can lead to permanent facial scarring and disfigurement. Accutane treats these bumps by slowing the rate of chemical production that leads to skin breakouts. It was originally recommended for people with severe acne that did not respond to other treatments,but has gained in popularity in the past 25 years and is prescribed more and more frequently for less severe acne How Accutane works Exactly how Accutane works on a cellular level is unknown but we do know that it affects all four ways that acne develops. 1. It dramatically reduces the size of the skinsoil glands(35%-58%) and even more dramatically reduces the amount of oil these glands produce (around 80%). 2. Acnebacteria(P. acnes) live in skin oil. Since oil is dramatically reduced, so is the amount of acne bacteria in the skin. 3. It slows down how fast the skin producesskin cellsinside the pore, which helps pores from becoming clogged in the first place. 4. It hasanti-inflammatoryproperties. Researchers have published several studies attempting to gauge whether people with mild to moderate acne can achieve long term remission of acne with lower dosages of Accutane. Initial data is showing that people with mild to moderate acne may be able to achieve long term remission with significantly lower dosages, and thus suffer fewer side effects, including lower incidence of scarring. Relapse rates with lower dosages do not seem to increase, leading some researchers to posit that it is not cumulative dose that brings about permanent clearing as much as it is the length of time that the oil glands are suppressed. Intermittent dosing (taking Accutane only 1 week of every month) appears to work less well, producing significantly poorer outcomes for more than half of the patients studied. Why is Accutane better Only solution for severe acne Effective than antibiotics Quick results as compared to other remedies Easier to consume and continue , just an oral pill Long term results Lesser scares left after complete course Dosage:[4] Accutane should not be consumed unless prescribed by your physician, and its dosage should be as prescribed by the physician. Please refer the table below to get a glimpse of the approximate dosage of Accutane. [5]Precautions: Before starting Accutane treatment, make sure you tell your doctor about any other medications you are taking (including prescription, over-the-counter, vitamins, herbal remedies, etc.). Do not take vitamin A supplements. Vitamin A in high doses has many of the same side effects as accutane. Taking both together may increase your chance of getting side effects. Do not receive any kind of immunization or vaccination without your doctors approval while taking accutane. Inform your health care professional if you are pregnant or may be pregnant prior to starting this treatment. Pregnancy category X (accutane may cause fetal harm when given to a pregnant woman. This drug must not be given to a pregnant woman or a woman who intends to become pregnant. If a woman becomes pregnant while taking accutane, the medication must be stopped immediately and the woman given appropriate counseling). Because of the extremely high risk that a deformed infant can result if pregnancy occurs while taking accutane in any amount even for short periods of time, for both men and women: Do not conceive a child (get pregnant) while taking accutane. Two methods of effective contraception are recommended for women of childbearing potential, unless absolute abstinence is the chosen method. Discuss with your doctor when you may safely become pregnant or conceive a child after therapy. Do not breast feed while taking this medication Side effects of Accutane: [6] Doctors prescribe Accutane when other acne treatments fail. Because serious cases of acne can be such a physical and social burden, patients may be willing to tolerate some of the common side effects that come with Accutane use, including dry skin, headaches and cold-like symptoms. A less-common side effect of the drug is pseudotumor cerebri – benign intercranial hypertension. This is a condition in which the brain acts as though there is a tumor when there is not. It can lead to blindness. Early signs of pseudotumor cerebri include headache, nausea, vomiting and visual disturbances. About half of Accutane users are women of childbearing age, making birth defects associated with Accutane use a significant concern. Unfortunately,Accutaneis linked to a series of serious side effects, including bowel diseases like Crohn’s disease, liver damage, depression, and miscarriage and birth defects if taken during pregnancy. Apart from these excessive dose of Accutane can lead to hypertension, suicidal tendencies, depression , liver damage, gastrointestinal problems , hearing impairment etc, there for as a matter of fact it is higly recommended to consume Accutane under medical supervision only.

The traditional theory has the Roman Empire being violently overturned by barbarian Germanic tribes who started invading en masse during the last years of the fourth century. That wasn’t the first time that the Empire had to deal with pressure on its borders, but this time it eventually collapsed because it had already declined as a civilization due to internal problems. The first scholar to support this line of thought was Gibbon in the late eighteenth century. His great, multi-volume, work goes by the title ‘The Decline and fall of the Roman Empire’, which speaks for itself as for its writer’s thoughts (?). He argued that the most important cause which brought about the end of the Roman Empire was the expansion and gradual predominance of Christianity. First, the new religion and the structures that came with it (such as the church and the monasteries) interfered with the distribution of wealth inside the Empire, by accumulating it in institutions that were inaccessible by the state. Second, its pacifist ideology reduced the army’s will to fight and its theology corrupted the classical ideals through the spread of superstition. Another scholar arguing along the same lines was Rostovtzeff. He states the Late Empire was in retrogradation?, a sad and decadent remnant of its former self, partly because of the increase in absolutism during the reigns of Diocletian and Constantine and the emperors who succeeded them. Together with Gibbon, his arguments form the core of the ‘traditional’ theory, which puts stress especially on the issue of ‘decline’ as the main reason which made the disintegration of the empire, as a political entity, eventually inevitable. Due to the work of these two scholars, the ‘Fall of Rome’ has ended up being seen as something like the platonic idea of decline. Along with the traditional theory, we should consider the work of a more recent scholar. Following the same methodological path as Rostovtzeff, Jones credited the barbarians with the destabilization and collapse of the Roman Empire. Their invasions, he argues, should be seen as a destructive agent which placed strain on the Roman administration. At the same time, in a well-known passage, he speaks of a large part of the population that was consuming without producing anything, such as senators, soldiers and the clergy. These ‘idle mouths’, as he calls them, partly a result of barbarian pressure again, at least as far as the army was concerned, was the main reason for the economic waning of the Late Empire. Jones’ contribution was twofold. To begin with, he proposed a new chronological period, extending further than 476, the date traditionally considered as signaling the moment of death of the Roman Empire. His ending date was 602, the year of the emperor Maurice’s death as he strongly believed that the Roman Empire continued its existence, albeit geographically diminished, in the East, at least until the advent of the Slavic tribes in the Balkans at the end of the sixth century. This way, he managed to provide a connection between late- and post-Roman societies, hinting that there might have been a causal relation between the two. Secondly, he breathed new life in a period that was all but put aside by his contemporaries as of not much particular interest and after him scholars gradually started to perceive the Late Roman Empire in its own right. This was countered by ‘traditionalists’ in 2005 with the publication of a book under the title ‘The fall of Rome and the end of civilization’. In this book, the author Bryan Ward-Perkins is arguing fervently that the fall of Rome was a violent experience for the people involved, which involved much bloodshed and catastrophe. It was centered more on radical change than gradual transformation and was characterized by decline and resulted in a decline in civilized values which actually that a number of Roman cultural achievements were lost. Although this view has its merits and should not be discredited without consideration, it needs to be examined carefully because it conceals the danger of oversimplification. First, it can be argued that the author has gone too far with his emphasis on violence and catastrophe. Violence, no matter how hard on a society, is not by principle an agent of radical change which rules out any chance of transformation. Human history is full of violence and it would be surprising if the fourth and fifth centuries did not involve any at all. Despite Ward-Perkins vivid depictions, much of what was considered Roman did not disappear with the Empire. Roman qualities, such as a literate culture, can be shown to have survived as late as the seventh century, proving that the devastating barbaric invasions did not actually have such a devastating effect after all. Stemming from that, we should examine if there was a specific moment in time when Rome actually ‘fell’. If we cannot point out such an instance, then we should regard it as a more gradual process. Italy, for example, shows that society was able to maintain its order in the face of much devastation. And if, as Ward-Perkins himself admits, ‘there was no single moment, not even a single century of collapse’, then we should discard catastrophist theories as inadequate and try more. We should also keep in mind that the author comes from an archaeological milieu and, as a result, most of his proof comes from the study of material evidence. Archaeologists of the period tend to be advocates of the notion of decline more often than historians, mainly because such a decline is much more evident in the material remains of the Late Roman era. In addition to that we have to be careful with the origin the evidence. In the case of Ward-Perkins, he doesn’t hesitate to support his theory on data from Britain, but Brittania (i.e. the part of Britain which was conquered by the Romans) had never been the archetypal Roman province. So Britain is far from being the typical example of what happened after the Romans had left the island, particularly given the fact that we can find other provinces of the Roman Empire, which shared a completely different fate, such as Egypt and Syria. When talking strictly about the west, one has to be extremely cautious when trying to combin e both the archaeological data with historical sources that might give the impression of continuity. One way approaches, such as the one only just discussed, will not do. Late Antiquity With good reason one might ask what the need of such a dramatic reassertion of the traditional view on the fall of the Roman Empire. The word traditional itself implies the existence of an opposite, neoteric theory. In 1971, Peter Brown published a book which defied all the assumptions of the traditionalist school. His book ‘The world of Late Antiquity: from Marcus Aurelius to Muhammad’ argues about continuity, transformation, cultural and religious renewal. The enthusiasm that the book was met with in academic circles, especially in the United States, resulted in the banishment of terms as catastrophe, change, crisis and decline. Brown was influenced by the views of an earlier scholar, Henri-Irà ©nà ©e Marrou, who argued that late antique art had not deteriorated and that it should be looked at in its own terms. Brown was influenced by the work of Henri Pirenne. In his works the Belgian scholar supported that there was continuity to be found in terms of long-distance trade in the Mediterranean which was not affected by the barbarian invasions but collapsed with the great Arabic conquests of the seventh century. Brown placed a new stress on the period resulted in a recent rethinking of Pirenne’s views through the prism of the newly proposed notion of continuity. Finally, Brown could also be considered an influence because, as we saw earlier, he was the first to propose a causal connection between the Late Roman Empire and the post-Roman era. Thus, given the entailed predominance of continuity which was easily detected in themes such as art and religious belief, a new historical period has been founded with its own characteristics, that of Late Antiquity, in which â€Å"some of the basics of classical civilization still survived†. Its boundaries stress from the third to the eighth century, but they are still unfixed, with every writer proposing different dates, according to the issues they deal with. Brown relied heavily on the methods of historical psychology and psychoanalysis. This methodological innovation is a general trend among scholars of Late Antiquity, particularly those in the United States. They have more or less identified themselves with the kind of history that falls outside the scope of socio-economic history. For example, the history of Christianity has proven very fertile for studying Late Antiquity, especially the effects it has had on different aspects of human life, such as death, sexuality and the family. Thus, this school of thought has made astonishing contributions in such fields as gender and culture history, the history of mentalities and of popular belief. Such methods, however, often tend to function with no respect to periodization and as such they lead to fragmentation. Indeed, the work of these scholars shows more emphasis towards individuals and their perspectives than to the society they live in. As a consequence, post-modernist theories concerning source analysis have relied heavily on the works of scholars after Brown, while, in the meantime, the old philological approach has been largely abandoned. Ancient texts are dealt with not so much for their narrative value, but as agents the mentality of their authors. Of course, works exclusively focused on different authors have a lot to offer to the ongoing discussion of the period, but dogged commitment to them might create a handicap for our understanding of the period as a whole. Furthermore, partly as a response to the traditional view of catastrophe, scholars of Late Antiquity have been particularly keen on seeing continuity and transformation. But this attitude can be harmful in two ways. First, the notion of continuity seems to have an overshadowing effect on the particularity of issues in a certain period. If everything is proven to carry on from the past not changed in the least, then historical periods will automatically lose their individual tone, by which it is defined. Simultaneously, by relying to heavily historical sources (as they provide ampler evidence for continuity) we may be overturned by the findings of archaeological research (in the way Ward-Perkins was). Second, emphasis on continuity and transformation is the expulsion of their opposites from contemporary history books. Terms such as â€Å"crisis† and â€Å"decline† seem to have been anathematized in modern research and this has started to raise objections, even by scholars who are not polemicists of continuity itself. Powerful words like these falling into disuse can only be detrimental for historiography. These terms are usually avoided because of their moral implications, and it is somehow assumed that if there is decline someone needs to be charged with it. But we always have to bear in mind that history is a science and historians should concentrate purely on the facts of their research. Nevertheless, Late Antiquity’s impact shouldn’t be confined within strict scientific limits. Continuity along with transformation, apart from being objects of historiographical debate, is also too powerful of terms to be overlooked by contemporary politicians. From 1993 to 1998 a large research project, funded by the European Science Foundation (ESF), brought together scholars from across Europe. Its title was â€Å"Transformation of the Roman World† and its aim was to provide a widely accepted interpretation of the fall of Rome, along the lines of a smooth passage to what was to become today’s Europe. Two thousand years after Augustus history is being repeated: the European Union is commissioning its â€Å"poets† to create its own foundation myth. Late Antiquity is a new period that has had to carve its way bravely into powerful, deep-rooted views of modern historiography, much like the barbarians who had to carve their kingdoms fighting against the mighty Roman Empire. But unlike the former, somewhere along the way it had to make sacrifices which rendered it less effective as a means of interpretation and more limited in its scope. Also, it came to associate itself with â€Å"allies† with political agendas, who might have promoted it, but in the long term damaged somewhat its credibility in terms of objectivity. After all that, it is not surprising that Avril Cameron, a great advocate of the Brown school, herself admits â€Å"‘Late Antiquity’ is in danger of having become an exotic territory†, just before suggesting that it should be tested also in the fields of economic and administrative history. Pekepersonal thekerkerethoughts-synthesis/LA+med west Thus far, we’ve witnessed in brief a powerful debate: Ward-Perkin’s book came as a vivid reaction to a whole school of thought formed around Brown’s work, which itself was another dramatic response to an older tradition. But extremism is inherent in violent reactions, because only through opposition one side can define itself and stand out in relation to its adversaries. Naturally, the existence of opposition itself should not lead us to believe that one side is absolutely right, while the other is absolutely wrong (and in most cases they are not). Rather, it should direct us towards an evaluation of the new conclusions that emerged from the conflict and setting the problem on a new base. However, it should be noted that both books have something in common: they are heavily focused on different geographical areas, where their conclusions seem to be more frequently affirmed. This way, Brown was able to find plenty of continuity in the eastern part of the Empire, while Ward-Perkins discovered a great deal of catastrophe in its former western provinces. As Jones had underlined long before those two, historians often tend to forget that only a part of the Roman Empire actually fell to the barbarians. So, nothing would be amiss if things were so well defined, but they are not. And although it seems that Late Antiquity is better suited for early Byzantine history, there are also those medieval scholars who deem it rewarding to try their hand at the concepts that this new approach brought with it. Late Antiquity and early medieval history One of these was jean claude van dam (‘the muscles from brussels’) mouahahhahahaha Late Antiquity and the barbarians The exclusion of notions of violence and catastrophe from the debates concerning the fourth and fifth centuries, which Late Antiquity scholars promoted, created a historiographical vacuum and a way had to be found for depicting the relations between the Roman Empire and the new arrivals. If violence could not be used to describe them, then the sources had to be searched for a different sort of evidence. The subsequent reexamination of the sources gave birth to the notion of accommodation. The first scholar to do that was Walter Goffart. In a well-known book, published in 1980, he described in detail the way that the barbarians were settled on Roman lands. According to Goffart a fairly straightforward arrangement between the late Roman administration and the barbarian tribes can be derived from the sources. The critical feature of this arrangement was that the Empire relinquished its rights on the taxation of the region in which a group of barbarians were settled and instead those taxes would be collected by the barbarians. However, according to this theory, there was no expropriation of land, no partition of it to smaller units to be apportioned and no need for extra money from the tax payers. The only one who had something to lose in the process would be the central administration and this definitely helps explain the fact that there is no sign of any noteworthy resistance from the local population in the regions where the barbarians were settled in this way. The aforementioned theory was further elaborated by Durliat. After analyzing the sources rigorously, he managed to take Goffart’s theory one step further. He argued that land tax in the Late Roman Empire amounted to no more than 20% of the harvest and it was collected and administered by the curiales. They split it in three and kept one third for their city’s expenses. The other two thirds were then sent to Rome to be used for the needs of the army and the central administration. With the advent of the barbarians, this system was very conveniently transformed to accommodate them: the curiales no longer sent anything to Rome but instead conferred the appropriate amount to the barbarian group that happened settle in their city’s administrative region. Furthermore, he argued that this modus operandi continued unaffected after the fall of the western Roman Empire, in the different successor-states, until the collapse of the Carolingian Empire. This theoretical synthesis was attractive to scholars, not only due to its clarifying simplicity and astonishing applicability, but also because it served to explain the lack of any negative sentiment in the sources. The importance of it becomes clearer, if we take under consideration that actually there were complaints on the part of the sources, wherever the barbarians had not settled peacefully but by force. As we saw earlier, the curiales were unconcerned if two thirds of the land tax changed recipients, as long as they were still obtaining their part undiminished. One can easily imagine the effect that this argument had on the debate on continuity, especially since it was centered on Western Europe. Of course, this theory didn’t fail to raise some eyebrows. Liebeschà ¼tz criticized Durliat’s arguments on a twofold basis. First, he doubts that late Roman cities actually collected for themselves any part of the imperial taxes and second, he argues quite convincingly that such an agreement would eventually provide little actual security to the settling barbarians, as security is usually better ensured through direct property of the land, than through any fiscal rights. Whats more, it seems perfectly reasonable to assume that it was exactly this security that the barbarians were looking for and of course, their position of power during the last centuries of the Roman Empire made sure that they were not likely to settle for anything less. Moreover, Durliat’s theory was commented on further in an article in 1998. There, Wickham analysis Durliat’s arguments and dismisses them one by one. Initially, he disagrees that the strict fiscal meaning which the latter ascribes to terms such as possessors and fundus is actually the one intended by the legislators of the fourth and the fifth century and in so doing he undermines the theory from the beginning. But he goes on to challenge other aspects such as the idea that Church constituted a part of the state administration in the post-Roman kingdoms (and thus church property consisted only of fiscal lands) and the view that servus is the term used to suggest a free landowner. By providing hard evidence following the chronological order (Late Empire, Romano-Germanic Kingdoms, Carolingian Empire), Wickham manages to discredit convincingly the arguments about fiscal continuity throughout this period. But, it should be noted that in the end of his article, where he dis cusses briefly the issue of continuity, he states that while he is not averse to it himself, it should not be considered tantamount to complete absence of change. However, the predominance of continuity does not sit well with terms like ‘barbarian invasions’ and ‘Germanic immigration’. So, historians had to find ways to circumvent this problem; they started by looking at the ethnic identities of the Germanic peoples, because it could be argued for example that there was no clear-cut sense of common identity between barbarian groups, such as the Goths, or some common characteristics that defined ‘Germanic’ then it would be possible to downplay the importance of the aforementioned terms. This way, Late Antiquity affected another heated debate (and in the meantime was affected by it); that of European national identities. The contribution of Walter Goffart has been essential at this point. Apart from fiscal continuity, in his Barbarians and Romans, he was also arguing about against the existence of definite ethnic identities among the barbarians. Another centuries-old historiographic tradition before him interpreted the movements of the Germanic tribes according to contemporary political ideas. For example, before the Second World War, Kossina had argued that there was a separate, identifiable culture to be associated with every Germanic tribe we come across in the sources and in 1961 Wenskus had maintained that there was a core of tradition carried by the elite of each barbarian group, according to which the whole mass of the tribe was defined. But, according to Goffart ‘migrations have served as the factual underpinnings of early Germanic unity’. Thus, if he could prove that no such unity actually existed, the migration and invasion theories would lose all sense. Indeed, he argues for a ‘short history’ of these peoples oblivion was a result of translocation. The common past of these peoples at any point stressed as back as the time before their last migration. He refuses to use sources of the sixth century such as Jordanes because, in his opinion, they only reflect the ideas of their own times and cannot be trusted for their evidence of the distant past. Finally, after taking under consideration also the deductions of archaeological research, he thinks that, if one wanted to look at the discontinuity provoked by the advent of the barbarians, he should definitely put the emphasis on Rome and its security. It was the appeal that the Empire had on the barbarians and not their own expansionist agendas that brought about the fall, in an ‘imaginative experiment that got a little out of hand’. It is therefore clear that Late Antiquity has given historiography of ethnic identities new areas of research to explore. This process gets even more complicated with the interference of modern international politics and historians of the Early Middle Ages recently find themselves and their research at the center of contemporary political debates. One can discern a pseudo-history in the making, which serves political and nationalistic purposes in the sense that it tries to define distinct nations that were created centuries ago once and for all. Another assumption is that by right these nations should form separate political entities, according to their defined ethnicity and territory. To sum up, the search for continuity of the Late Antique scholars might not have been successful in the field of fiscal policies and accommodation but it ascertained the fact that we cannot presume long histories and ethnic identities of the Germanic peoples. This certainly confirmed transformation instead of catastrophe and crisis for some aspects of the fourth and fifth centuries but it surely proved that there was much discontinuity and heterogeneity concerning the notion of identity. And since the Early Middle Ages are of such a great importance in the international political stage, scholars of the period should benefit from the results of research in this field in order to prevent their academic field from becoming a plaything in the hands of international politics.

Possible Solutions For Environment Problems Essay

Global warming has become a major issue discussed over Medias and governments all over the world today. It is a problem that threatens the whole world because of the destructive impacts it can have on us humans and to the environment. Global warming is not a new phenomenon. It is often referred to as the gradual rise of the earths near surface temperature as a result of increased emissions of greenhouse gases from human activities. The green house gases are carbon dioxide, methane, nitrogen, ozone and water vapor, they act as a blanket that traps enough heat from the sun to warm the earth. This is the green house effect as it is essential to life, for without it the earth would be so cold and would be uninhabitable. If not enough are in the air then the earth would become cold, but if too many gases are released into the air, then we have the problem of things heating up. The releasing of green house gases by humans slowly warm the earth, potentially changing the world’s climate pattern causing sea levels to rise and more disastrous effects. Now that the causes and effects of global warming are known, there can be strategies done to minimize its causes and effects. To achieve this countries and individuals have to work together to fight global warming, agreements made at the Kyoto Protocol is to minimize burning of fossil fuels in world leading countries of greenhouse gas emission including the United States and China. The earth’s atmosphere is made up of gases; carbon dioxide, methane, water vapor and nitrogen, these gases are known as the greenhouse gases, they trap heat from the sun to warm the earth. Without them the earth would be so cold. Most scientists believe that the sharp increase of greenhouse gases released into the atmosphere is warming the earth’s climate. Gases such as carbon dioxide, CFC and methane are the most released gases due to daily human activities. Exhaust from automobiles, smokes from coal fired power plants and deforestation are the major contributors to greenhouse gas emission. The largest greenhouse gas emitters are the densely populated and more developed countries such as the United States, China and Russia. Motor vehicles are the highest emitter of greenhouse gas; they produce high levels of carbon monoxide and nitrous oxide which is released into the atmosphere. Another major source is the burning of fossil fuels (coal, oil and wood) by power plants to generate electricity. In 2003 the United States released  more than 5 million tons of gases from power plant alone. An increase of forest fires or deforestation for land clearing has lessened the amount of trees. Trees play a vital role in trapping carbon dioxide, when deforestation occurs more carbon dioxide is released. The Amazon is the largest carbon dioxide forest emitter (Protecting Forests). Any resource consuming method releasing quantities of carbon dioxide, methane, nitrous oxide or even water vapor contributes to the effect (Tapia 2007). These mass emissions of greenhouse gases cause the atmosphere to trap more heat thus leading to the warming of the earth. As the temperature rises the earth becomes hotter and hotter causing polar ice caps and glaciers across the globe to melt. The Intergovernmental Panel on Climate Change (IPCC) is a scientific body tasked to evaluate the risk of climate change caused by human activity, has released their latest report (Summary for Policy Makers 2007) on how global warming is affecting the earth. The report shows that the â€Å"sea ice in the arctic is shrinking in all seasons, most dramatically in summer†¦.Important coastal regions of the ice sheets on Greenland and West Antarctica, and the glaciers of the Antarctic Peninsula, are thinning and contributing to sea level rise†( IPCC 2007, p.109). Another cause of sea level rise is the thermal expansion of water; this means that the increase in the earth’s temperature heats the ocean causing it to expand. The combination of water from melting glaciers, ice sheets and the thermal expansion causes sea level to rise. Rising of sea level leads to erosion and flooding but the most disastrous of all is the drowning of low lying islands and cites, the island of Tuvalu is slowly sinking from the rising in sea level. A warmer ocean can change weather patterns and could cause extreme weather events as already experienced in 2005 weather condition caused number of tornadoes and hurricanes in the United States and Asia( Tapia, 2007). The continuous rise in temperature and melting of ice caps is changing the landscapes in the artic circle making it uninhabitable for animal species including polar bears, seals and whales because they are only adapted to cold climate. Other effects include severe droughts in dry climate areas such as Africa has already leaded to famine. Fatal heat waves have already triggered massive bush fires in Australia and Europe, not only that but these heat waves could cause skin cancer. The  IPCC’s report concluded that if the temperature continues to rise within the next 50 years or so, its effects on us humans and our planet will be more disastrous (IPCC, 2007). However there could be strategies done to prevent global warming and its effects. Since us humans are the main source of global warming we are the only ones that can prevent its causes to minimize its devastating effects. As mentioned before that human activities such coal power plant emissions and deforestation are amongst the leaders of carbon dioxide emitters. Large industrialized countries should cut down the level of carbon dioxide emitted from coal fired power plants. The Kyoto protocol is an agreement made under the United Nations Framework Convention on Climate Change (UNFCC), their goal is to reduce the emission of greenhouse gases in large industrialized countries such as the United States (Kyoto Protocol 2008). Another step is the banning of coal fired power plants, director of the NASA Goddard Institute for Space Studies told the â€Å"Terra Daily† that â€Å"There should be a moratorium on building any more coal-fired power plants until the technology to capture and sequester the (carbon dioxide emissions) is available,† he believes that the suspension of coal fired power plant is the key to cutting carbon dioxide emission (Staff Writers, 2007). Moreover we could use energy from renewable sources such as wind and solar power because it is much cleaner than fossil fuels. For example, more than 40 percent of the US states is increasingly using renewable energy because it is more affordable and cleaner than fossil fuel (Clean Energy, 2007). While reducing industrial emissions is critically important, we should also stop deforestation of rainforests such as the Amazon where trees are cut down, burned and cleared for agriculture and cattle grazing (Forest Holocaust & Protecting Forests). We could stop deforestation and replant more and more trees to replace the fallen trees.

Symbolic And

Their efforts seem to have paid off, as evidenced by the enduring well-defined, and strong images of some of the world's popular brands (e. G. Marlboro, Ivory, Pepsi). In line with this evidence, theorists and practitioners (CB. Gardner and Levy, 1955; Park et al. , 1986; Rise and Trout, 1 986) have recommended that developing, communicating, and maintaining a brand's image is crucial to its long-term success. 32 Brand image important The importance of a brand's image in its long-term success necessitates having a framework for strategically managing the image over the long term Park et al. , 1986).Brand managers have had very little direction for setting up such a conceptual framework. One notable exception is brand concept management (BCC) proposed by Park et al. (1986). BCC proposes that every brand image should be based on a brand concept or a brand-specific abstract meaning. In its general form, a brand concept can be either symbolic or functional, and thus comprises one aspect of a brand's image. Functional brands satisfy immediate and practical needs. Symbolic brands satisfy symbolic needs such as those for self-expression and prestige, and their racial usage is only incidental.For example, in the category Of wrist watches, the brand Cassia would be considered a functional brand since its usefulness lies primarily in its ability to tell the time correctly. The brand Moved, on the other hand, would be considered a symbolic brand since it is used primarily for its status appeal, and its ability to tell the time is only an incidental reason for its usage. Once a concept is selected for a brand, park et al. (1986) advise that it should be maintained over the brand's life for sake of consistency. Symbolic or functionalWhile the notion of brand concept management is intuitively appealing, the proposition that brands can be either symbolic or functional in their appeal to consumers raises a number of interesting issues. The first issue is whether symbolism and functionality are two distinct concepts or are two ends of one brand concept continuum. In addition to the uniqueness of these two concepts, park et al. (1986) assume that each of these concepts is unidirectional. Whether that is really so has not been examined in empirical research to date.Also, to our knowledge, no measures or scales have been plopped that would assess whether a particular brand is symbolic or functional. Thus, empirical research has not directly examined these related issues. An understanding of such issues would also be very useful to marketing managers in planning positioning strategies for their brands. In this exploratory study, a set of scales are developed to assess a brand's symbolic and/or functional value to consumers. In the process, we JOURNAL OF CONSUMER MARKETING, VOLT. 15 NO. 1 1998 up. 2-43 @ MAC UNIVERSITY PRESS, 0736-3761 examine the issue of distinctiveness and dimensionality of the two brand incepts. Two schools of thought Brand concept Backgro und There is a long tradition of research into human needs and motivations. While there are a large number of theories and models that explain the nature of human motivation for consumption behavior, a simple typology would suggest two distinct schools of thought. The rational school or the â€Å"economic man† model suggests that consumers are rational and try to maximize total utility.They do so by buying products based on objective criteria like price per ounce or gallons per mile (Coffman and Kane, 1994). In arriving at this excision, consumers generally go through a variety of cognitive operations that include deciding the importance of each attribute in a product category, gathering information about competing brands' attributes, judging the levels of each attribute in competing brands, and finally using a judgment rule to decide on the optimal brand (for an exhaustive review of the information processing literature, please see Bateman, 1979).A number of researchers, how ever, contend that the rational model is appropriate only for goods which consumers value for their tangible and utilitarian benefits, and does not adequately capture their motivation for consuming products that satisfy their emotional wants (CB. Levy, 1959; Ditcher, 1960; Holbrook, 1980). For example, Hiroshima and Holbrook (1982) note that the rational model does not capture the multistory imagery, fantasy, fun, and emotions associated with the consumption of some products.They refer to this type of consumption, based on individual tastes and intangible product benefits, as hedonistic consumption. Thus, in contrast to the rational or information processing approach, the emotional or hedonistic school holds that consumers' motives are motional in nature. In this perspective, individuals use personal or subjective criteria such as taste, pride, desire for adventure, and desire for expressing themselves, in their consumption decisions (Coffman and Kane, 1994). Consumer behaviorist's have long recognized the importance of both types of motivations (CB.Katz, 1960; Metal, 1983). Empirically, several researchers have noted the existence of these two different types of motivations and the different product attribute categories that tap into these motivations (CB. Metal, 1988; Metal et al. , 1990; Sahara and Siring, 1991). Thus, both theory and research support the idea that consumers' needs are driven by functional/ utilitarian as well as by symbolic/expressive motivations. In keeping with this tradition, park, Gasworks, and Manacling (1986) noted that consumers' needs could be classified as being either functional or symbolic.They assert that functional needs are related to specific and practical consumption problems whereas symbolic needs are related to Selfridges and social identification. To tap into these two different types of needs, Park, Gasworks, and Manacling (1986) proposed that all brands should have a â€Å"brand incept†, which is an overall abst ract meaning that identifies a brand. They suggested that a brand concept be either symbolic or functional, thus tapping into consumers' symbolic and functional needs respectively. Park et al. S (1986) brand concept management framework advises managers to select a specific concept for a brand at the time of its introduction and then use the marketing mix to support and reinforce it over the brand's life. This helps consumers understand with clarity what a brand can do for them. JOURNAL OF CONSUMER MARKETING, VOLT. 15 NO. 1 1998 33 Functional or utilitarian deeds The existence of different types of motivations among individuals suggests that within most product categories, consumers' needs could be either functional or symbolic in nature, and brands could be positioned to satisfy either of these two types of needs.Thus, functional or utilitarian needs of consumers could be exploited with a â€Å"functional† brand, I. E. One positioned with a functional brand concept or meanin g. Similarly, a brand could be positioned as a â€Å"symbolic† brand to tap the needs of those who wish to enhance their self-image or their social image. Park et al. Rather argued that brands should be positioned to appeal to either one of these types of needs, but not both, for a number of reasons. A brand concept that is both functional and symbolic poses problems for consumers because they cannot clearly relate the brand to either their functional or their symbolic needs.In addition, it increases the number of competing brands and makes brand image management difficult. This argument, however theoretically compelling, has not been tested in empirical research. In one related research, park et al. (1991 ) Were able to show that nonusers' reaction to functional extensions of functional brands was more favorable than their reaction to prestige extensions of functional brands. In the same study, consumers also displayed a more positive reaction to prestige extensions of prest ige brands than to functional extensions of prestige brands.Please note that, in this study, the authors assumed that brand concepts could be either functional or prestigious (not symbolic). Unanswered questions Several questions, though, remain unanswered. Are functional and symbolic brand concepts adequately distinguished in consumers' minds? If so, what are mom characteristics that help in distinguishing these brand concepts? Is the prestige of a brand an adequate representation of a brand's symbolism to its customers? Are functionality and symbolism merely the two ends of a continuum?In any event, is there a mechanism to assess the functionality or symbolism of brands? The paucity of research to illuminate these issues resulted in this study. This study was set up to answer the preceding questions: to investigate the phenomenon of the functionality or the symbolism of brand image and to develop scales that would help classify a brand as functional or symbolic. Apart from the the oretical contributions, the issues raised in this study have a number of managerial implications for brand positioning.Method In line with this study main objective of exploring the issue of brand mage functionality or symbolism, scales containing items thought to measure a brand's functional or symbolic value to consumers was developed. The scale was validated by testing the scale's ability to discriminate between brands a priori identified as functional or symbolic. Correlations among the items in the scale and exploratory and confirmatory factor analyses of the data were seed to investigate the dimensionality of brand functionality and symbolism.Stimuli lie Pairs of brands were identified in a few commonly used product categories, such that one brand in each pair was, a priori, thought to be functional and the other symbolic. In other words, the first brand was thought to primarily satisfy functional needs whereas the second brand was thought to mainly satisfy the symbolic needs of consumers of the product category. The pairs of brands which were selected are shown in Table l. 34 Product category Symbolic brand Functional brand Watches Role Timex 2 Sports shoes Nikkei Converse 3 Cosmetics Lana ¶me Amiability 4 Hair cream Paul Mitchell Suave 5 Ice cream Hagen Dads Scaliest Table l.Item generation Adjectives or phrases thought to indicate a brand's symbolism or functionality were first generated by the authors and a focus group of graduate students at a university. The focus group noted the difficulty of coming up with adjectives describing functional or utilitarian appeal. Based on these processes, three adjectives and phrases were identified as relating to functionality and 17 as relating to symbolism. Three sets of questionnaire items Three sets of questionnaire items were developed for the 20 adjectives and phrases.The first set of questions sought respondents' agreement with various statements about individuals' use of a brand to express themselves. Th e second set of items sought respondentBrand symbolism The 17 adjectives and phrases representing brand symbolism were assessed with three sets of items. In the first set of items, respondents were to agree with these statements: (1) â€Å"people use (brand) as a way of expressing their personality'; (2) † (brand) is for people who want the best things in life†; (3) â€Å"a (brand) user stands out in a crowd†; and (4) â€Å"using (brand) says something about the kind of person you are†. The second set of items sought to evaluate these brand characteristics: (1) hemolytic; (2) prestigious; (3) exciting; (4) status symbol; and (5) distinctive v. Invitational. The third set Of items evaluated these characteristics Of the brand's user: (1) sophisticated v. Simple; (2) not at all v. Very romantic; (3) not at all v. Very successful; 35 (4) unique v. Ordinary; (5) stylish v. Plain; (6) expressive v. Subdued; (7) glamorous v. Sedate; and (8) not at all v. Very ele gant. Survey design and administration Two separate questionnaires were prepared with questions on five of the ten stimulus brands such that each questionnaire contained questions about one f the brands within a product category.Thus, a subject would answer the above questions with respect to either a symbolic brand or a functional brand within a product category but not both. This procedure was used to eliminate any comparative biases in responses. The survey was administered to 62 graduate students at a major south-eastern university. Rest Its Analysis of correlations TO obtain a preliminary idea of the pattern Of relationships among these items, the correlations among the items were first examined.

Methodology and methods Methodology The chosen methodology for this project is a case study. The term methodology is an overall approach for a particular study (Sim and Wright, 2000). Case studies have been described as collecting small qualitative data (Gerring, 2007) focused on narrow, in-depth examinations of chosen topics (Savin-Baden and Major, 2012). This chosen methodology works well with my interpretivist paradigm approach whereby I intend to explore the viewpoint of one participant (Baxter and Jack, 2008) and depict the issues they encounter as a teacher. It is also beneficial to my project as it is a pilot study therefore is on a small scale and likely to provide in depth data which could be applicable to others (Merriam,†¦show more content†¦To be able to explore different areas of inquiry and have valuable data from my interview I will need to encourage my participant to talk freely and to feel relaxed when responding to my questions (Clough and Nutbrown, 2007). By collecting this data this way I w ill be addressing my research question (Sim and Wright, 2000). As my research question is an exploratory one carrying out a semi-structured interview is beneficial to my work because I intend gain insight and understanding to the issues teachers face. However, an issue with my chosen method is it will take place over the phone. This limits my data and I because my participant may not feel comfortable opening up without face-to-face interaction. However this may benefit my work as the phone can be a comfort for them. Due to this project being a small-scale pilot study, the paper requires only one example of a data collection method. As a result of this I am limited as I only have the opportunity to interview my participant once (Newbury, 2009). In spite of this, the loose structure of the interview can cover all topics which are vital to my research (Bell,2010). I will also have the advantage of taking my time during the interview.
