Western & Native America Medicine

In such a situation, I would first create a good rapport between Mr. Wolf, his wife and I. I would start by thanking them for visiting the health care centre and for allowing me to run some tests on Mr. Wolf. I would then advise him that it is a good thing to look after our health as this is the only way that we will be able to live to see tomorrow. As Broome, B. & Broome, R. , (2007) says, the Native Americans value their traditions very much. It is therefore necessary to act as one of them or rather to respect these values and demonstrate to them that they are important. By doing this, I will be able to prescribe some new medication and at the same time, I will be certain that Mr. Wolf will respect and adhere to the directions that I would give him. After examining him, I would give him the antibiotics that he is supposed to take. I would try to educate him on the importance of these drugs as they would help him to regain his health. I would do this by explaining the consequences of prostatitis and the effects or damage that it might have if it is not treated. I would not discourage him from taking his herbal medicines that he was prescribed. Instead, I would thank him for visiting the healer or the health counselor or advisor. I would encourage him to continue taking the herbs as they were directed by the healer or the health counselor. In addition, I would also advise him to take the medications that I have administered to him without fail. This way, he will feel that I am supporting him and at the same time I am respecting his culture. According to Cohen (2003), American Indians or the Native Americans value their tradition very much. This means that if at all I will act as if I am not respecting this fact, there are chances that he will not follow my directions and therefore he might not get well at all. Alternatively, there are some herbal medicines that are not likely to do well with the hospital medicine. I would therefore ask him to go home with the medicine that I had administered to him and make sure he takes them. I would explain to him that there are some herbal medicines that would counteract with the hospital medicines that we are taking. I would advise him to come with the herbal medicine that he is taking so that we can see if they have any content that might react with the antibiotics. This way, we would be able to prevent any further reaction in his body. When they bring the medicine, I would analyze it and assess whether it has any reaction with the antibiotics that I would have given him. If there is a reaction, I would change the antibiotics, alternatively, I would try to advise him that there is a serious reaction that might take place if he took both the medicine that I administered and the herbal medicine at the same time. I would then try to explain to him that the diseases that he is currently having is very serious and therefore he need to give it a first priority. According to Moses, L. & Wilson, R, (1985), Native Americans are known to speaking in parables. I would therefore try to formulate a story about a patient who had such a disease and who defied or rather who refused to take the medication that I had given him and chose the herbs. He only stayed for five months before succumbing to the illness. This would be in the aim of convincing Mr. Wolf to give the antibiotics the first priority and stop taking the herbs for some time. I would advise him that he can immediately go back to the herbs onces the antibiotics are over.

The Contemporary Life in Xijing, An Ancient Chinese City

In 1993 China was hit with an â€Å"event that caused a great literary and publishing earthquake†¦ † The Abandoned Capital hit bookstores in late July of 1993. This novel is Jia Pingwa†s graphic and sexual explicit insight on the contemporary life in Xijing, an ancient Chinese city. The novel never indicates time references but it is understood by readers that it is right after the Cultural Revolution. Jia is a well-known novelist that was famous for writing â€Å"pure literature. † So it was to everyone†s amazement that Jia wrote a novel that was so pornographic. The novel is about a middle-aged writer that engages in sexual immorality, deceit, and corruption. Many critics say it†s autobiographical but Jia denies all accusations. The Abandoned Capital was written in a way that Chinese readers have never seen before. During the Cultural Revolution self-indulgence was looked down upon, thus so was sexuality. The result of this was the ignorance of sexuality for the Chinese for years to come. To some, the sixty detailed sex-scenes in the novel were the first time they encountered sex. Jia, a peasant from the ancient capital of Xian, admits that he put the sexual content to keep readers interested but says his novel was really about the corruption of China. He further confesses that he got all his research from maopians, porn videos. Another reason for the shock from the novel was the fact that Jia had broken the three rules that they were so accustomed to by Chinese readers. 1) He downplayed the hero describing him as a â€Å"sexual pervert† with no power, no money, no influence and sex was the only way to escape his empty life. 2) He wrote explicitly about sex and 3) he did not offer a happy ending. Jia also said that he chose a writer as the main character because he knew them best. Not too many people see the novel†s true statement, which is the clear description of the â€Å"Chinese social system from the inside out. † Most critics see The Abandoned Capital as a novel with â€Å"unbearable vulgar sex scenes. † Yet I believe that bad press is always better than no press, and boy did Jia receive plenty of bad press. Actually the over all reception of the novel was pretty much fifty-fifty. Most of the elders and elite†s of China demanded if Jia was going to write about sex freely, why couldn†t he write it with some â€Å"beauty and depth. † Even Jia†s fellow writers poked at his writing saying â€Å"he wrote exactly the way he f***ed. † And then of course there are the feminists. They see the novel as an obvious â€Å"male chauvinistic† view of women. They say that in Jia†s eyes â€Å"women are playthings, having no business in life except being the object of male appreciation and pleasure. † They also added, â€Å"it†s as if Jia has never stepped into the twentieth century. Even the author of China Pop, Jiangying Zha comments on her distaste of the novel saying â€Å"all that dirt†¦ † As I said before, not everyone disliked the novel. Evident fans of the novel were merchants at local bookstands. The first print run of 480,000 copies was completely sold out within two months! By the end of 1993 the novel had sold over a million copies. The following summer rumors of a ban on the novel began going around. This of course gave the novel even more publicity and made Chinese readers even more curious. Other fans of the novel compared D. H. Lawrence†s Lady Chatterly†s Lover, which also contained sexual scenes, to Jia†s novel. One Beijing graduate student said reading both may cause a young man to masturbate but â€Å"with Lawrence he may feel a but ashamed of himself afterwards, but never with Jia! † And some bluntly say, â€Å"there is absolutely nothing perverse in this novel†s sex scenes. † A friend of Jiang adds that Jia is describing China†s current social system. With the â€Å"daily transactions of power, how people manipulate at all levels, the bribing, the networking, and the giving and receiving of favors. He further adds that people in the social system â€Å"know the invisible rules, and they know they can†t beat the system. They also know they can play along with this old game. † It is said that no other Chinese novelist has ever illustrated this picture so well as Jia. Another friend of Jiang†s is a business lawyer that agrees with the fact that The Abandoned Capital is the Chinese society in a â€Å"nutshell. † He even describes his encounters with taking advantage of the system. The Cultural Revolution left China with numerous changes. However, as noted earlier, the Cultural Revolution left China as uneducated about sex as a ten-year-old child. In the seventies sex and romance disappeared from Chinese arts and literature. During these times men and women stayed single while displaying interest only in the revolution. The children of the revolution grew up in a vacant environment. They were not taught sexual education like the U. S. Jiang herself had not learned about the birds and the bees until she was nineteen. It was so bad that movies with kissing scenes were censored for children. During the mid-eighties the reform years were in full swing. With it came the market of pornography. Guangdong, Fujian, and Hainan Island were the first mainland provinces to acquire the market. The flood of pornography astounded the Chinese government. There was nothing they could do to stop it. If they closed down one pornography ring a number of others would take its place. Every city and province in China has felt the effects of the flood of pornography. Some incidents include a television station worker that was so caught in his porno movie that he actually connected the wrong line and aired the movie to the entire city. Some companies award clients with porn videos. By far the most disgusting display is children under ten were among the audience in cinemas showing porn. The lack of sexual educational programs will just keep this industry booming. Where else will the Chinese â€Å"fill in the blank spot important to millions? † Some parts of the population watched their farm animals mate for their education. This led one couple to have â€Å"eight years of anal intercourse†! I believe without proper education on any subject leads to uninformed versions of that subject. Being a man I don†t totally think pornography is bad, but it shouldn†t be used for sexual education. Growing up in a Chinese family I know very well how the red children of the revolution felt. However, living in America, there were so many ways to be educated on sex. I myself learned the facts of life through television and friends. I also was privileged to receive sex education in high school. Taking sex ed really removed a lot of myths about sex for me. The times have changed and China has to change with it. China is always playing catch up to the rest of the world. Today sex is a freely talked about subject and China should realize this. Without proper sex education teenagers of China will be misled and probably endanger themselves. I believe Jia Pingwa didn†t write his novel to emphasize sex. I myself haven†t read the novel but I do truly believe that he wrote the fictional novel to describe his feelings toward the Chinese society today. Most bold writers are often misunderstood and this case is no different. Maybe living in America all my life has given me the freedom to think this way but if China would lighten up a little it would be only then the real learning begins.

Importance of Money in Sports

Man is constantly in search of new knowledge and discoveries, thus science is constantly being studied and updated with every new discoveries. The study of science has make a huge impact in our lives by helping to improve our quality of life and enabling us to make use of the knowledge of our surrounding to come up with inventions that are extremely useful in our daily lives. Despite the huge advantage of science which made lives easier for us, there are also negative repercussions which can arise out of science. Hence if there's no regulation in place, a world dominated by science may turn from a dream a nightmare for future generation. A world dominated by science may have dire consequences as that would mean that man would be able to manipulate Science according to how they want it to be. Currently, with experiments on stem cell research, cloning and all the bio-medical discoveries, it would not be long before man starts cloning humans in the near future. Therefore the future generations may have to live in a world where most of the things are unnatural and created by man. The situation may also end up just like the society that was being described in the novel † Braw New World†, whereby humans are dehumanized and created in the labs instead of being born by their mother naturally,. This will be a nightmare for the future generation since the idea of â€Å"family love†, which is present in today's society will be eroded due to the fact that the parents will no longer take care of their children since young and the meaning of being a parent may no longer be the same again. Hence, a world dominated by Science may become a nightmare for future generation with the eradication of natural emotions and relationships. The moral values that people believe in currently will be degraded gradually if we allow science to dominate the world. With the discovery of Science and the use of technology being part and parcel of our lives, people will no longer be unfamiliar with all the scientific discoveries and the benefits derived from them. Therefore even though some practices such as the cloning of human is still forbidden and considered illegal now, these rules may change over time as people may start to accept these ideas due to the change in lifestyles or surroundings, Therefore a world which is dominate by science may become a nightmare to the people as the moral and ethical values which people believe in currently may be completely diminished in future. Without such values, there would be chaos on earth since people may be free to do as they wish and there are no fixed set of guidelines for them to follow. On the other hand, science may be a dream for future generations since science will help human improve their standard of living and it will be a stepping stone for human to create a utopian world. Man has been doing a lot of things just for the sake of making the world a better place for people to live in. All the research, studies and explorations done by man have the purpose of letting us have a greater understanding of the world which we live in. By making use of all these knowledge, we would then be able to manipulate them so that we would have greater control of the world to make the world in which we live in a more comfortable place. Therefore the world will be considered a dream for the future generations. However, man will never ever be satisfied with his own lives. As the quality of living may improve gradually over time with the help of science and technology, people will keep yearning for a better life since man is greedy in nature and is never satisfied. This will become a never-ending cycle whereby people will keep asking for more, thus the future generation may not think that the world in which they would be living in is their ideal world. Hence in the point of view of the future generation, the world in which they would be living in may not be considered to be a dream to them. Therefore even though science may make our world a more idealistic place to live in, there has to be a limitation to the use of Science as an unregulated world will result in a society which may be too inhumane and where people may be dehumanized.

Average Cost Curves Case Study Example | Topics and Well Written Essays - 1000 words

Average Cost Curves - Case Study Example These critical business decisions will be made with the help of Average Cost Curves. These graphs will convey information about optimum production levels and the most beneficial expansion scheme. Total Average Cost is the average fixed cost plus the average variable cost. The Short Run Average Cost (SRAC) is the average cost of the product when at least one input variable remains fixed. This is usually the building or the plant used in manufacturing. The Long Run Average Cost (LRAC) is the average cost over a longer time period when all input variables have changed. It takes into account new plants, buildings, and large capital investments. Though these curves will vary depending on the individual product and situation, for a successful business they will almost always assume the same general shape. The shape of the SRAC curve and the LRAC curve are influenced by the changing input variables plotted against differing production levels. As Acme begins production, the cost of the first few units is heavily influenced by the fixed costs such as the lease on the building. The graph will start at a high average cost per unit. As they increase production levels, the fixed costs become spread out over more units and the SRAC begins to fall. At this point, the graph will begin to slope downward as the quantity rises. The SRAC will continue to decrease as production increases toward full capacity, as both fixed and variable (due to material volume) cost per unit declines. This period of declining SRAC is known as the economy of scale. When the factory has reached full capacity, its resources are being optimised and the total average cost per unit has reached a minimum. Manufacturing beyond this point will begin to increase the average cost as variable costs rise, and the process will enter a period of diseconomy of scale. Added expenses such as temporary labour, overtime, and additional management are a few of the factors that can contribute to the rising variable cost. Here, the graph turns upward reflecting the higher average cost. As more units are produced, the average cost continues to rise dramatically reflecting the inefficiencies involved with over capacity production. This is known as the law of diminishing returns. A key component and indicator on the graph of the SRAC is the Marginal Cost (MC). This is the total cost of producing the next unit. With an efficient factory running near capacity, this will be at a minimum, and less than the average. However, going beyond this point will cause the marginal cost to spike upward on a steeper slope than the average. When the marginal cost line crosses the average, production is at its most efficient. As marginal costs rise, it pulls the SRAC curve up with it, though at a less responsive rate. Acme could remain profitable in this area of increasing costs and diminishing returns as long as MC is below the selling price. However, to maximise resources it is desirable to keep the SRAC at a minimum. The point at which the marginal cost begins to rise and cross the SRAC is the point at which Acme must consider expanding their production capabilities. Acme has already planned for this expansion. They are no where near market saturation and the product design has a long life ahead of it. Their sales are increasing and they have studied various plans on the

Hunting Tourism Essay Example | Topics and Well Written Essays - 250 words

Hunting Tourism - Essay Example Various reports show that endangered species such as the lions have reduced by 30% in Africa and the cats are perceived as seriously imperiled. In one of the reports that were published in the year 2011, it revealed that the economic and the environmental benefits of hunting tourism in countries such as Tanzania, Botswana, Namibia, Benin, and Cameroon among others were negligible. It was alleged that around 272 million acres had been open to the sport though the returns were quite dismal. In addition, as much as some scholars allege that hunting tourism generates tourism, it was determined that less than 10,000 people were hired on part time and permanent basis yet approximately 100 million people lived in the aforementioned countries (Bland, 2012). Despite various claims that hunting tourism increases revenue and helps the local communities, there has been no enough proof. The pro-hunting firms argue that there are only 3% of the revenues that goes to the communities that have been affected by poaching and the rest goes to foreign and government outlets. It is also to be noted that killing of animals such as the lions is irresponsible considering that the healthy members are endangered and when the adult male, which is the most sought after animal is killed, there is destabilization of its pride, leading to increased number of deaths. The act is also counter-evolutionary since it consists of selecting the healthy, robust, and large males that protect their cubs and mates as well as contributing positively to future generations (Flocken, 2013). Therefore, killing of defenseless species is definitely a bad idea and there is a need to have a balance. It is normal to hunt and kill wild animals for food but there is a need for the government agencies, the pro-hunting organizations, tourist oriented firms, and other stakeholders that are affected to come up with ethical and sustainable hunting methods that can enhance conservation. Ensuring there is balance

Health Care Disparities in the United States Research Paper

Health Care Disparities in the United States - Research Paper Example Yes, it is possible to eliminate health disparities in the United States. Eliminating the disparities that exist in healthcare is politically sensitive and rather challenging because they are somehow intertwined with a controversial record of race relationships in the US. Â  Some of the approaches that can be applied in eliminating health care disparities include increasing the competence and number of healthcare practitioners in areas which are underserved, expanding health insurance coverage, increasing the awareness base on root and arbitration to decrease the occurrence of health care disparities and raising community and health care practitioners understanding of racial or ethnic health care disparities. These strategies combined with others by the government are bound to be successful in eliminating health care disparities in the US. Â  The similar theme is that exists in the assigned articles is that eliminating health care disparities is key to improving the general quality of health care provided in the US. Most Americans do not often receive the quality health care that they deserve or on other occasions, the health care they get causes them harm (Williams, 2007). It is such incidences that have resulted in health care disparities in America.

Are political parties still the central actors in politics Essay

Are political parties still the central actors in politics - Essay Example Politics, therefore, does not occur in a proverbial vacuum, consisting of a variety of interactions between society and the political actor and other relevant political figures that maintain responsibility for community governance. Politicians are often affiliated with a specific political party, an organisation that aims to influence the development of government party that are considered appropriate for securing the party’s objectives and agendas. Political parties serve as coalitions consisting of like-minded politicians that have the same ideologies and expectations for government. The question at hand is whether political parties are still the central actors in politics. Though political parties are highly influential and often serve as the underpinning for how politicians identify themselves comparatively to other political figures, there is little evidence that political parties are the principle actor along a political model or system. In fact, it would appear that the media is now the central actor in politics as media services a much broader role in society as it pertains to political activity. The media is able to influence politicians and societal members, promote real-time political activities, engage society about politically-relevant events, and even serve to expose questionable political behaviours. Political parties are no longer the central actor in politics. Political party affiliation is a method by which to classify a politician and their unique agendas as compared to other politicians. In the United States, political parties were established in the late 1700s when it became clear to those running for public office that they would need to garner public support to obtain a majority vote competitively (Nichols 1967). As there were no established political parties in the United States prior to 1787, the ideologies of the Republican Party and the Democratic Party (the two main parties in the country) became

The Legal and Ethical Considerations of Marketing in America Essay

The Legal and Ethical Considerations of Marketing in America - Essay Example The American Marketing Association (AMA) is committed to promoting the highest ethical standards among its members. They are guided by the ethical norms that state that they should not harm; they should foster trust in the marketing system; and they should embrace ethical values (American Marketing Association, 2011). These ethical values include honesty, responsibility, fairness, respect, transparency and citizenship. It is unfortunate though that not all companies honor these guidelines set by AMA; thus, the existence of numerous marketing strategies which are illegal and unethical. Unfair and illegal marketing practices of corporations are those where it withholds pertinent information or misrepresents information. Example, a bank marketing officer was able to convince a client to apply for a loan because of the low interest rates but later on the client realizes that if he prepays the loan, he will have to pay a prepayment penalty. The information on prepayment penalty was deliberately withheld just to close the transaction. This could be considered an unfair marketing practice by the bank. One popular legal issue that most manufacturing companies are faced today comes in the light of America’s concern for the environment. The words â€Å"biodegradable† or â€Å"environmentally friendly† are often seen in the packaging of products nowadays. The Federal Trade Commission and the National Advertising Division (NAD), and the Council of Better Business Bureaus have come up with guidelines regarding the use of the word â€Å"biodegradable† as many companies are loosely using the term to promote a better image for their products and to convince the consumers to buy them because they are â€Å"environmentally-friendly† (Gekas, Harrold, & Dixon, 2010). The legal issues in the packaging, specifically the labeling of products is one aspect in the marketing strategy which must be considered by organizations.

Concepts of Disaster Myths in Disaster Research

Concepts of Disaster Myths in Disaster Research Disaster myth is one of the most component in disaster research. Disaster myth is a significant part of disaster research. It not only contains important characteristic of this field but also affects other element in disaster research. It merits the attention of many researcher. To have a deep understanding of disaster myth, a broad view of disaster research should be taken into account. Definition: The issue of devising a definition or assessing consensus on a definition plays an important role in not only theoretical but also empirical research. In Handbook of Disaster Research, Ronald W.Perry’s What is a disaster is a prominent research in dealing with this issue. He argued that in regard to definition, he tried to recount the efforts to define disasters by social scientist, instead of seeking a new definition. In this paper, he clarified the problem of definition by specifying its type, purpose, and audience. First of all, he set the type of definition as an area of study, not a concept, although these two dimension are not clearly separable. Therefore the definition that he proposed will address concerns of paradigm and do so by identifying critical features or characteristics of disaster (Perry, 2007) – which is categorized as real definition, more appropriate to define an area of study. Since disaster will always mean many things to many people, and the desc ription will serve many different purposes – thus there will be many definitions (Perry, 2007). He narrowed the scope of definition by following Quarantelli’s research to explain the definition under social scientist’s angle. Hence, the important aspects need to be concerned when defining disaster research is the social context and tradition. He divided disaster definition research into 3 main areas: the first is the classical approach, second is hazards-disaster tradition and the last is explicitly socially-focused tradition. In the first part, with the most prominent representative scholar as Fritz, who proposed a definition of disaster in 1961 and its impact has remained until recent time, the main characteristic of disaster definition is dealing with social order disruption (Fritz’s therapeutic community is a significant example) and the emergent norm thinking. The main image of disaster in these research is negative consequences. It was manifest on the definitions that were presented in the first three definition published (by Wallace, Killian and Moore) and also the following empirical researches. Until recent time, there are still many scholar follow Fritz’s premise, but they has added some variance to it. Through these researches, he claimed the evolution in classical approach of definition in contem porary disaster research. These research was inspired by Fritz’s definition, but they also focus more on the process, adaption and change in disaster, as a cycle of adjustment from the disruption of â€Å"non-routine event†. The second area of disaster research is captured from hazards perspective. As its name, despite the fact that they may be concern about social and other aspect, the main focus is still the target agent. In this perspective, disaster is viewed as an extreme event that arises when a hazard agent intersects with a social system (â€Å"the human use system†) (Perry, 2007). Although this approach is cticized as paying too much attention to the environmental aspect of disaster and neglecting or not giving enough attention to social aspect, it is still considered as an attempt to define disaster and provide a new angle to explore the field. The classic elaborations of this approach is Burton, Kates and White. From the basis of hazards-oriented studies, until now, research direction of hazards scholar slightly moved from what might be considered an â€Å"agent centered† approach to a greater focus on vulnerability (Perry, 2007). The scholar started to add the social nature as w ell as social consequences in their studies. It has gradually moved to vulnerability, the social side of research, in spite of hazard origins. As can be seen from the development of this approach, disaster research should be examined first at it social side. It led to the third approach: socially-focused approach. This third tradition see disasters as a social phenomenon. This definition has roots from classical approach and is developed as the changing focus of hazards approach from agent centered toward vulnerability. This premise focuses mainly on social origin of disaster. Some scholar must be mentioned is Barton, Quarantelli, and Dynes. They have published their typology of disaster. For example Barton used his typology to address the cross-classified dimensions of scope (national, regional, segmental, local) by concentration of time (Perry, 2007). He emphasized the focus of the studies is on social dimensions of events, not the events themselves. In Quarantellli’s typology, disaster (1) are sudden-onset occasions, (2) seriously disrupt the routines of collective units, (3) cause the adoption of unplanned courses of action to adjust to the disruption, (4) have unexpected life histories designated in social space and time, and (5) pose danger to valued social objects. This definition has been followed by many scholar, as can be seen from literature. Although it has root in classical period research, it has added it significant features and developed much more further. Another approach to define disaster in socially-focuses direction is focus on cross-national or cross-cultural aspects. It emphasized the social structure of the definiton. In brief, these scholars see the definition in social relations angle. The 2 things that make it different from classical period approach are it characterizes disaster as a social disruption that generated from social structure and might be remedied through social structural manipulation s (Perry, 2007); and social structure can be seen as social change â€Å"analytically frozen at one point in time† (Quarantellli, 2005a, p.340). By listing up the 3 main areas of disaster definition approaches, in the end, author tried to assess levels of consensus between them. He emphasized on Quarantelli’s paradigm of disaster research with two main ideas as follows: disaster are social phenomena, and disaster is rooted in social structure and reflects the processes of social change. This paradigm again reiterates that event itself is not yet a disaster, it have to based on social aspect. Furthermore, it lead to the vulnerability aspect. Beside this, another consensus is the magnitude of disaster should not be measured by the losses of people or property, but by the failure of the normative or cultural system. It also showed the consensus of issue of resilience. The consensus of social disruption and emergent norm thingking has still remained. Finally, effort on defining disaster also focus on its social time and space rather than physical time and space. Meanwhile, there are also disagreement about these definition, as what kinds of characteristics should be included, the problem of taxonomy, and other issues. In an efforts to solve the problem of categorizing, Quarantelli (2005a, p333) distinguished disasters, catastrophes and crises. Boin , Stallings, and Rosenthal differentiated disasters and crises. As Quarantelli aruged, attention should be paid for classification systems. The taxonomy is the significant issue that researchers need to deal with in order to effectively examine disaster phenomena. In the end of the paper, researcher proposed agenda for future research. Here again he reminded reader of how important the role that definition plays in the field. There are many of empirical work, but conceptualization still remains unsolved. Lacking of this important point, the field will be fulled of individual research but without a systematic view. He also mentioned the concern of taxonomy, as the classification systems still need to be examined carefully. In conclusion, author has fully synthesized the development and different approach when defining disaster – a basic and central part of disaster research. By providing 3 main traditions of research in disaster definition, the consensus in term of disaster’s characteristic has been explained thoroughly. Moreover, he also proposed the problem remains in the field, as further research should pay attention to conceptualization issue and classification systems. Only by doing this that research can solve the problem of definition, reach closer to the consensus in the field. This paper gave reader the insight into the field, since they can get the broader view of disaster research. The second paper we need to take a look at in order to have a general view of disaster research is The social science study of disasters and mass communications written by E.L. Quarantelli (1987). In this paper, the author has summarized the previous reseaches on social disaster research to depict the present overall state of knowledge. Therefore pointing out the focus of research field, analyzed significant themes of researches through the number and research orientation of studies. He also synthesized the studies related to mass communication in disaster research and finally proposed the way for future research Quarantelli (1987). Plagiarism As trying to provide a overall view of past and current research, he summarized the development of research field. Although the first systematic social science disaster study has ever been undertaken was started from 1920, until the end of World War II that social and behavioral research of disasterous events started to have any continuity and began to accumulate a body of data (Quarantelli, 1987). He chose it as a starting point to evaluate the pioneering efforts of research. At that time, there were 3 organizations that made great contribution to the establishment of fundamental basis. It was National Opinion Research Center (NORC), Disaster research group (DRG) and Disaster Research Center (DRC). Though there was a little discrepancy between research object of these organizations, caused by their differences in research orientation. For instance, NORC paid most attention to reactions of victims, while DRG focused more on group behavior. Despite of that fact, their shared the common feature at research entities that studied both natural and technological disaster and the reseearchers were mainly sociologists. Moreover, beside the victim, transmission of warnings message of potential disaster was also attracted attention from researchers, while little attention was paid to mass communication organization, both from theoretical and empirical studies. When conducting the research about warning message transmssion of media, warning process was the main purpose, not the operation of mass communication. The author emphasized on the unequal coverage of research, since it paid very little attention on institutional area. The reasons provided for this kinhd of dispropotionate research were the problem of methodology because it is hard to apply audiences quantitative method towards mass communication systems and the funding agencies. Another dominant feature of research at the pioneer studies was they did not recognize the â€Å"dual role† that mass communication plays in disasters. They just focused on the reporter role, furthermore, emphasized on the doubt of its validity when reporting disasters, known as disaster mythology. By doing this, they neglected another role that mass communication plays – the role of major organizational actors in preparing for and responding to disasters. Depart from the pioneering efforts, after 1960s, it marked a next stage of disaster research. It has been a remarkable development of both number and scope of research in compare with the earlier period. The author highlight some major themes found in research findings and observation to synthesize the knowlege gained by social science researchers in term of individual and groups’ behavior that mass media reports in emergency time. Therefore, pointing out the part remains little or unexplored, to suggest recommendations for further research. There are two main themes, covers individual and organiztional behavior. Individual behaviors are described as showing the strong ability to adapt to extreme situation of survivor, their actively behavior in rescure efforts, their stable mental health condition, their choice when choosing friend, family’s place rather than public shelters. Scholars (Fritz, Barton, Dynes, Drabek, Quarantelli and Kreps) concluded that victims absolute ly have ability to deal well with disaster. There is a very high consensus that these behaviors are very different from what media report about victim during emergency time. The image of victim behaviors depicted by media is panic, passive, go crazy, lose control, searching for public help. The discrepancy between reality and media report and audience belief is characterized as the â€Å"myths† of disasters (Quarantellli and Dynes, 1972). The second theme is also related to disaster myths, it is description of organizational behavior in disaster time. As conveyed from media report, organizational behavior can be seen as effective, almost indispensable, there is a strong emphasis on the critical role it plays in disaster situation. However, the actual behavior of organizations which was examined by the researchers shows a sharp contrast. In reality, orginizational behavior is ineffective, and even have negative effect in rescue process, as weak ability of managing effort and poor decisions made by public and private bureaucracies (Quarantelli, 1985a). In brief, these two research themes of individual and organizational behavior which relate to disaster myths show the discrepancy between actual behavior and image conveyed by media report. Hence, mass media is responsible for not framing the false image of behavior in emergency time. In searching for explanation, some researchers have stated that mass media personnel ten d to take a â€Å"command post† view of disaster (Quarantelli, 1987). Through looking closer to a series of specific studies, the author reiterated the limited number of researches about mass communication in disaster research. Although research in Japanese, French have a slightly higher focus on mass communication, in comparison with research in English langague, the quantity of research regard to mass communication remains small. He also listed some unexplored questions and research areas, such as research relates to operation of naitonal systems in disaster, functioning of cable system, disaster-relevant aspects of magazine productions (Quarantelli, 1987). The disproportion of focus between print media and electronic media is also a problem need to be examined. After listing the specific studies, he concluded that there is a prominent increase in number of empricial research on mass communications and theoretical formualtions efforts in term of mass media operations in the filed. The researcher also proposed the factors that contributes to this acce leration. (Perry, 2007) References Perry, R. W. (2007). What is a disaster? Handbook of disaster research (pp. 1-15): Springer.

Modelling Tool for Photonic Crystal Device Issues

Modelling Tool for Photonic Crystal Device Issues Chapter 4 SIMULATION DETAILS OF THE PROJECT In the past 10 years, photonic crystals (PCs) have attracted much scientific and commercial interest. The research and design work for PCs starts from accurate modal analysis of the device. Once the modes are found, structure can be simulated for that particular mode and the results of power spectra can be observed at the detector. In this chapter we will discuss about the modelling tool used for solving various problems related to photonic crystal device mentioned in next chapters. In our work, Opti-FDTD v11.0, a proprietary of Optiwave is used as a simulating tool to fulfill this purpose. 4.1 Introduction to FDTD Opti-FDTD is a user-friendly graphical interface that allows the designing of photonic devices in an efficient manner. It provides accurate computer aided simulations with the proper analysis of results. It is a powerful and highly integrated software package which is based on the finite-difference time-domain (FDTD) method. FDTD technique implies the solution of maxwell equations with finite-difference expressions for the space and time derivatives. FDTD schemes are especially promising for the investigation of PBG structures, as they provide an opportunity of analyzing the spatial distribution of the electromagnetic field in PBG structure. Opti-FDTD enables to design, analyze and test nonlinear photonic components for wave propagation, scattering, reflection, diffraction and other nonlinear phenomenon. The method allows for the effective simulation and analysis of structures with sub-micron details. Such fine scale implies high degree of light confinement and a large refractive ind ex contrast of materials to be used in design. Since FDTD method calculates electric and magnetic field at all points of computational domain, it is required for the domain to be finite. For this purpose, artificial boundaries are inserted in the simulation space. In FDTD perfectly matched layer (PML) acts as a absorbing layer for wave equations. In numerical methods, it truncates the computational regions while simulating problems. 4.2 Design Tools of Opti-FDTD Opti-FDTD is used to design photonic devices, simulate and analyze results. Design tools are available in toolbars and menu options. These tools include waveguide primitives, editing and manipulation tools, and special layout regions. Fig 4.1. Main layout of Opti-FDTD Designer Design tools of Opti-FDTD include designer, simulator and analyzer. 4.2.1 Opti-FDTD Designer This section created the desired layout on a wafer that is saved in a file with the extension .fdt. Opti-FDTD designer is opened from the start menu. This section enables a user to work on multiple layouts of project at the same time. One can store and retrieve projects using .fdt files. In addition to the standard cut, copy, and paste editing functions, we can: Scale elements or groups of elements swap overlapping elements snap elements to a grid of the layout zoom into or out of the project layout link elements together The main elements required to perform simulation of layout design include wafer, waveguide and input field. Wafer is the work area of design in Opti-FDTD. Each layout consists of only one wafer. It is a planar substrate on which we place and design the waveguides and cavities. The option of wafer properties is found in edit menu to modify the length, width and material of the wafer. Light wave propagates in Z-direction i.e. along the horizontal path on the screen. Discretization mesh is formed along the X-direction which corresponds to vertical path on the screen. Wafer is a necessary element for running a simulation. While starting a new project, the default material of wafer is air. Fig 4.2. Wafer coordinate system Waveguides are the building blocks of photonic circuits. Path perpendicular to the waveguide center defines the width of the waveguide. The default waveguide profile is air which can be changed while creating a new design. One can resize, rotate and move waveguides anywhere in the layout. Waveguide changes its color after selection. The orientation and shape of a waveguide can also be changed by dragging start/end handles. Properties of a waveguide can be viewed by double clicking it in the project layout. This opens the dialog box of waveguide properties where user can make required changes. Some major waveguide options provided by software include circular, elliptical and linear waveguides. From user point of view, waveguides can also be created by making some cells off in the photonic structure. Such a waveguide allows propagation of electromagnetic wave with minimum attenuation. The input field is an essential element in design to allow simulation to run. Its position is at an input plane which can be moved throughout the layout. It defines the light that enters the simulated structure. Geometric position of the input field and its orientation can be defined in the input field dialog box. Options available for input fields in the software are modal, gaussian, rectangular and user defined. The concept of input field is purely geometrical. It is a position and direction which defines a plane completely. Multiple input fields can be positioned on multiple input fields simultaneously. In a 2D design, input plane can be horizontal (perpendicular to X-axis) or can be vertical (perpendicular to Z-axis). Input field parameters must be defined carefully. The time domain parameters of input field can be specified as continuous wave or gaussian modulated continuous wave. Both the cases demand an input wavelength for the carrier wave. In Opti-FDTD all dimensions are defined in units of ÃŽ ¼m. Multiple input planes are distinguished with the help of ‘label’ facility provided by the software. Input wave can move in positive or negative direction depending on the option selected in the tab of wave configuration. An enable input field check box selects the input plane to be considered in calculation. Figures below show the placement of vertical and horizontal input plane. Fig 4.3. A vertical input plane for 2-D photonic crystal structure Fig 4.4. A horizontal input plane for 2-D photonic crystal structure Layout design in Opti-FDTD software includes profile designer, initial properties and layout designer. Profile designer define the material properties (refractive index of material) and channel profile. Initial properties set initial simulation domain properties including dimensions and material. Layout designer help to draw the lattice type (rectangular or hexagonal) and define the properties of the structure. 4.2.2 Opti-FDTD Simulator Opti-FDTD provides two types of FDTD simulations 32-bit simulation (performed by 32-bit simulators) 64-bit simulation (performed by 64-bit simulators) Opti-FDTD simulator monitors the progress, while the simulation is running. The simulation results are stored in a file with extension (.fda). After launching a 2-D simulation from Opti-FDTD designer, Opti-FDTD simulator displays the results of 2-D simulation. Fig. 4.5 shows the results of 2-D simulation for the structure shown in Fig. 4.3. Fig 4.5. 2-D simulation results (image map) in Opti-FDTD simulator Opti-FDTD simulator window contains output window and graph window. 4.2.2.1 Graph Window While running a 2-D simulation, a simulation window with several tabs appears. The first tab is the refractive index tab (Refr_Idx). Fig. 4.6 shows the refractive index distribution for the structure in Fig. 4.3. Fig 4.6. Refractive index distribution (image map) with palette Opti-FDTD simulator provides several types of views for graphs that include height plot and image map. Fig. 4.5 shows the image map of simulated field Ey. The height plot of the refractive index distribution of structure is shown in Fig. 4.7. Fig 4.7. Height plot of refractive index distribution 4.2.2.2 Output Window The output window contains notification and error tabs which display notifications regarding the status of simulations or any error that occur during simulation. Opti-FDTD simulator does not show this window by default. It can be accessed from tools menu. Figure below shows an example of output window. Fig 4.8. Output Window Simulation parameters can be accessed in Opti-FDTD_Simulator by selecting simulation > simulation parameters. For changing any of the parameters one should use Opti-FDTD_Designer. These parameters can’t be changed in simulator. Observation points can be used to obtain DFT and FFT transform. Observation line is used to observe power spectrum of the transmitted electromagnetic field. Opti-FDTD simulator provides the facility of PWE (plane wave expansion) solver. Fig 4.9. Simulation parameters dialog box Fig. 4.9. Simulation parameters dialog box The simulator provides tools for post-processing data analysis. Structure below shows the workflow of PBG structure analysis. Waveguide layout designer which provides necessary tools for designing a PBG crystal structure. After designing, PWE band solver simulation parameters are configured and PWE calculation is launched. After calculations results are automatically saved in .PND file and data is used for post-processing analysis. Fig. 4.10. Flow chart of PBG structure analysis The PWE band solver contains two windows including band diagram graph window and processing image window. PWE band solver graph window displays data of each eigen values based on each k-vector. During simulation, data is updated continuously from currently running calculations. Progress of calculations can be seen in the window. After completion of calculations, band diagram can be plotted either as band-gap data graph or line-connected data point graph. Fig. 4.11 shows a PWE band solver graph display for the structure shown in Fig. 4.3. Fig. 4.11. PWE band solver graph window Processing message window consist of notification and error tabs. This window displays textual information related to the activities performed in band solver. It provides notification on the k-vector value, tolerance, iteration number and time and date when results were being observed. Fig. 4.12 shows the notification window for the above-mentioned band solver. Error window displays notifications about processing errors. Fig. 4.12. Processing message window 4.2.3 Opti-FDTD Analyzer Opti-FDTD provides the facility to view power spectrum. Observation points are used for this purpose. To view the spectrum, observation area analysis can be accessed from tools menu. Fig. 4.13 shows the observation area analysis dialog box. Fig. 4.13. Observation area analysis dialog box The flow chart below summarizes the full procedure of designing, simulating and analyzing. Following algorithm is used to generate the flow chart. Create a new project Open Opti-FDTD designer Initialize the project Open waveguide profile designer Define the material Define 2-D channel profile Set up initial properties Create a design Draw a PBG crystal structure Set up the lattice properties Insert input plane Set up the input plane Insert observation lines Observe refractive index distribution Observe the refractive index distribution Set up observation lines Run the simulation Set up the simulation parameters Run 32-bit simulation Fig. 4.14.

[28] ] Analyze the simulation results Open Opti-FDTD analyzer Observe power spectrum Export results The block diagram illustration of the same is depicted in Fig. 4.15. Fig. 4.15. Opti-FDTD block diagram [ Courtesy: Ref. [28] ] Opti-FDTD analyzer first loads the files and processes it to simulator. Simulator runs the proposed design and exports data to other file formats [30]. Further chapters provide the methodology to improve the performance of photonic crystal biosensors. They also explain the application of such device in the emerging field of DNA photonics. A comparative account is also prepared between the performances of photonic crystal biosensor and surface plasmon resonance biosensor which proves the superiority of PC biosensors over SPR devices.

Art & Culture There are few places in the world with so rich and diverse an artistic and cultural history as Greece. In terms of archeology there are artifacts that are 200,000 years old, while architecturally Greece boasts Minoan and Dorian ruins dating back almost four millennia. Greece is also where drama originated, so there are plenty of ancient theatres to pick your way through Museums Greece is bursting at the seams with museums. Almost every single city, town, village, historical site, settlement and hole in the hedge has an archeological museum which details the archeological and historical significance of its surroundings Historical Sites There is certainly no shortage of these in Greece. Every city has their own specialties, like the Acropolis and the Ancient Agora in Athens, the Oracle at Delphi, the Palace of the Grand Masters in Rhodes Town, and so on. There are far too many to list here. It is suggested you get hold of a tourist map from the Greek Tourist Organization (EOT) which sets out all the ancient, Byzantine and medieval sites throughout the country. But some of the major historical sites you should make a special effort to see are listed below: The Acropolis, Athens The Ancient Agora, Athens The Byzantine monument of Nea Msni on Chios The Polycrates Wall and Eupalinos Tunnel at Pithagorio, Samos The Oracle at Delphi The Minoan palace city of Knossos, Crete The ruins of Gsrtyn, Crete Minoan ruined city at Phestss, Crete Arch of Galerius, Thessalon?ki The White Tower, Thessalon?ki The Sanctuary of Isis, at D?on. Dafn? Monastery, Greece’s largest Byzantine monastery Met?ora Monasteries, perched on mountain outcrops, in Kalabaka Climate Greece is perfect for those who enjoy the sun, as for over two thirds of the year the country basks under clear, sunny skies. Temperatures do vary, however. Winters are mild and rainy, with temperatures sometimes dropping to freezing point, especially in the north. Summers are long and dry, with extremes of 37Â °C (99Â °F), making the yearly mean temperature about 17Â °C (63Â °F). For those not overly fond of the heat, the mountainous areas offer some respite as they receive more rain in summer, and even snow in winter. Rainfall figures vary, depending on the region. Thessaly is very dry, receiving around 38mm (1.5in). Portions of the western coast paint a different picture, however, receiving about 1,270mm (50in) of rain. Greece can be divided into the northern and southern climatic regions: Greece :: essays research papers Art & Culture There are few places in the world with so rich and diverse an artistic and cultural history as Greece.

History and Politics :: Essays on Politics

History and Politics Dominica’s History and Politics are two subjects that become intertwined with each other as the politics have controlled the history of the island since before Columbus discovered it in 1493. From the indigenous tribes fighting each other for control to the Europeans racing to colonize Dominica the island has changed hands many times, which can be seen through the unique culture that exists there today. During these changes the politics of Dominica were altered as different tribes had different ways of ruling just like Spain, France, and Britain did too. Millions of years ago fierce volcanic activity began deep below the sea, in the region known now as the Caribbean. Some of these volcanoes managed to push their way up from the ocean floor to become islands; the tallest of these islands is Dominica. Since then Dominica has seen many different inhabitants, some stayed for thousands of years while others abandoned the island as soon as they arrived. From the ancient Ortoroid, Igneri (Arawak), and Kalinago (Carib), to the Spanish, French and English, every group left their mark and thus Dominica has a very rich and diverse history. The first inhabitants of Dominica were the Ortoroid who left the South American mainland around 3100 BC. They traveled in canoe type boats and used sails and paddles to navigate from island to island. One of the islands they settled on was Dominica, where they lived for over 2500 years. Evidence suggests that the Ortoroid where extinct by 400 BC. (www.Skyviews.com) The Igneri or â€Å"Arawak speakers,† were the next group to live on Dominica arrived around 400 AD. They were a peaceful tribe that had also traveled by boat from South America, and dispersing to settle on a number of different neighboring islands. During the 1,000 years that the Igneri occupied the island, a well – defined culture was developed that thrived as a result of the plentiful supply of fish and warm climate that is found on Dominica. (www.Skyviews.com) Sometime around the end of the 12th century AD, things took a bad turn for the Igneri. At this time the violent warlike people known as Kalinago, began to make their way up the Caribbean chain of islands, invading and conquering the islands they stopped at. By the early 1400’s they had reached Dominica, they named the island, ‘Wai’tukubuli’, which translates to, ‘Tall is Her Body’.
