The Rape Of Nanking And The Art - 1504 Words
As a species, humans have a long and bloodied history of attempting to eliminate one another to become dominant, from the Armenian genocide to the ethnic cleansing of the Tutsis in Rwanda. This mentality is not a new phenomenon, but has evolved to become even more lethal and prolific with the innovations in weaponry and transportation. Due to this disturbing universality, parallels are easily drawn between Iris Changââ¬â¢s The Rape of Nanking and the art that was being created in Europe and the United States during the time of Hitlerââ¬â¢s reign, including the work Seligmann, Stael and Albright. We must look to other global sources for this insight, due to the lack of photographic documentation in China and creation of art after the fact. The war crimes Japanese soldiers inflicted upon the people of Nanking are one of the most heinous examples of this idea of extermination, resulting in the loss of an estimated 200,000 to 300,000 lives. Thousands of women were raped, forced to take pictures with their assailants in pornographic poses, shamed and seen as being dirty, viewed as being subhuman. Soldiers were warned to eliminate the women they had raped, disposing of the evidence of what they had done. ââ¬Å"ââ¬ËPerhaps when we were raping her, we looked at her as a woman,ââ¬â¢ Azuma [a soldier] wrote, ââ¬Å"ââ¬Ëbut when we killed her, we just thought of her as something like a pigââ¬â¢Ã¢â¬ (50).

The Awakening ~ Mademoiselle Reisz A Pillar Of Moral Support Essays
The Awakening ~ Mademoiselle Reisz: A Pillar Of Moral Support Although Mademoiselle Reisz seems to be relatively insignificant in The Awakening, she has a profound influence on Edna. Mademoiselle Reisz is one of the only characters in the novel who can understand Edna's true character. Reisz inspires Edna to have a courageous soul that dares and defies (63). Mademoiselle Reisz influences Edna by acting like a sanctuary for her. When Edna feels bored, it would be in such a mood that she would hunt up Mademoiselle Reisz (58). When Edna returns to the city, she is compelled to visit Mademoiselle Reisz. When she visits Mademoiselle Reisz, her boredom is lifted away by Reisz's music and Robert's letters to Reisz. Edna loses herself when Mademoiselle Reisz plays music (64). Mademoiselle Reisz makes Edna feel happy by allowing her to read letters from Robert. Edna's eyes fill with delight when Mademoiselle Reisz shows Edna the letters (80). Seeing how happy Mademoiselle Reisz is as a non-married artist inspires Edna to be more independent and to pursue her desire to paint. This relates back to the meaning of the novel -- a woman's struggle for individuality while still being married. By spending time with Mademoiselle Reisz, Edna realizes that in order to be a separate self she cannot have the burdens of marriage and children (18). Mademoiselle Reisz also motivates Edna's endeavors. Mademoiselle Reisz encourages Edna to be her own individual. One way in which she does this is by defining the requirements for a genuine artist, to be an artist includes much; one must possess the courageous soul, she says (63). Since Edna wishes to become a genuine artist, these words melt into her soul (63). When Reisz says this to Edna, she is not just informing her that an artist is one who paints, but she is also implying that an artist is one who is willing to surpass the borders of society. Although Edna tries to surpass the borders of society, in the end she was not an artist since she took her life because she could not meet the requirements for a genuine artist. She was unable to surpass the borders of society to be her own person. Mademoiselle Reisz advises Edna on love. Reisz tells Edna that Robert loves her: it's because he loves you poor fool (63). She also explains the reasons for Robert's absence. According to Mademoiselle Reisz, Robert is gone since Edna is not free to listen to him or belong to him (63). Mademoiselle Reisz pacifies Edna by talking about Robert and love. Mademoiselle Reisz contributes to the meaning of the novel by being able to recognize Edna's awakening. By influencing Edna to be an artist, Mademoiselle Reisz helps Edna find the strength to be a courageous individual that can dare and defy (116). Unlike Mademoiselle Reisz, Edna cannot find the space and solitude that she needs to be an individual (26). Space and solitude are things that Edna cannot have on land since she is responsible for looking after her husband and children (26). Her family is a burden to her individuality. Edna also realizes that her individuality is more important to her than family. Edna faces her fate, and lifts her white body (115) away to the sea where she can find her space and solitude (26).

She gave the following examples: If she were younger, she would have enjoyed that trip. I wish I were stronger. or He wished he were stronger. à Somehow the second sentence feels odd to me. Using the verb flexed in the plural form with wish should also be used with he, she and (eventually) it?

Iââ¬â¢m happy to say I anticipated this verdict in my post on subjunctive were: To a large extent, English speakers donââ¬â¢t pay much attention to the subjunctive. The upshot of the Globe article is that although sites like this one still offer guidelines for its use, the subjunctive use of were is is a non-issue.

What caused the surge in oil price during the period 2000-2005 Essay
What caused the surge in oil price during the period 2000-2005 - Essay Example This projection is mainly attributed to the changes in demand and supply by the non-OPEC and OPEC members. The oil price surge is a major economic issue as it slows down global economic recovery. This paper highlights the major issues that are behind the oil price surge during the 2000 ââ¬â 2005 periods. In this essay we seek to address the question of the effects of additions to OPEC capacities and economic activities on oil prices (mostly in the future) and why oil prices are literally depend on the OPECââ¬â¢s ability to maintain control over the marginal supplies of oil. Global oil demand had a slow increase in the year 2000 ââ¬â 2005 periods than it did in the last five years. Each time when the demand growth accelerates annually, the prices are always seen to rise and vice versa. The yearly rate of demand growth has changed markedly over the last few years with this kind of growth dipping into a low of just about half a percent in the year 2001 and a then having a sha rp rise through 2004. During the year 2004, the oil demand had surged by 4% and this was the fastest rate since 1977. In the year 2005, the demand growth fell callously although its growth rate was maintained above 1%. A significant part of this growth was contributed by China and most of the rest of the developing Asia (Menecon Ltd. 2006, p1). The United States and other non-Asian developing countries accounted for the bigger share of the volume increase in demand during the 2000 ââ¬â 2005 periods. With the supply capacity going high in the recent years, the rise in demand has squeezed spare capacity in pushing up prices. Causes of Oil Surge during the 2000 ââ¬â 2005 Period During 2000 ââ¬â 2005 period great oil surges was experienced, the possible causes of this surge in oil prices include: supply, monetary inflation and the value of the US dollar, demand and investment demand. Supply Lower supply of oil is considered to be a main lasting fundamental cause of the risin g prices during the period 2000 ââ¬â 2005. The intermittent supply contributed majorly on the surges in oil prices and therefore, the oil price crises. Monetary Inflation and the Value of the US Dollar Price inflation develops from monetary increase and other economic policies. Wobbly monetary policy attained from the Federal Reserve and other central banks is listed as one of the major contributor to the increase in the oil prices. It therefore forms the main cause in the dollar devaluation and commodity speculation characteristic with changes in oil prices. The value of the US dollar also had some impact on the oil prices as oil is normally quoted and traded in US dollars. This means that the value of the dollar determines the rise or fall in the oil prices. Demand High demand for oil is also one of the main causes of the surge in the oil prices. The demand for the crude oil was seen to be growing at an average of 1.76% per year. This effective growth (in percentage) was recor ded from the year 1994 to 2006. Still, during this period (1994 to 2006), a higher rise of 3.4% was experienced in the year 2003 to 2004. As the demand for oil is on a high rise all over the world an increase in demand of 37% is expected by 2030 hence the demand for oil is projected to have an increase. Normally, increase in oil prices reflects on the global demand rise for oil. Prices usually affect the demand as the relationship between them is considered to be not a way street. If the demand gets a certain shift a direct impact on the oil prices will take place; when the oil prices get affected thy in general will lead to a (United Nations staff 2005, p6). Investment Demand Invest demand is also one of major issues to the surge in oil during the 2000 - 2005 period. Investment demand usually occurs when investors pay for future

Bulimia Nervosa Thesis Example | Topics and Well Written Essays - 1250 words
Bulimia Nervosa - Thesis Example People with bulimia nervosa are preoccupied by their body shape and weight. Their appreciation for food causes them to binge, but their guilt afterwards causes them to purge or turn to over exercising to make up for their binge. It is highly believed that bulimia nervosa contains psychopathological signs in its development processes in a person, meaning that mental illness and distress might play a role in the development of bulimia nervosa. Indeed, there is a correlation between people with bulimia nervosa and borderline personality disorder (Cooper, 2003). The characteristics of borderline personality bring about depression in people, as well as unstable self-image, identity, and behavior. The individualââ¬â¢s sense of self is also negatively affected. All of these aforementioned symptoms of borderline personality bring about negative emotions in regard to an individualââ¬â¢s self-image. They become uncomfortable being in their own skin, finding something wrong whenever they are presented with the opportunity. When a person develops a mental illness that causes them to reconsider their self-image and reevaluate their sense of self, other disorders can begin to be developed, especially those relating to their self-image. If an individual feels negatively about how they look, they tend to implement means that can make them feel better about themselves. Even if they remain unpleased about how they appear to themselves, they still feel better about the fact that they are at least trying to compensate for the damage that they believe they are doing to themselves. The symptoms that accompany bulimia nervosa are similar to those found in borderline personality disorder. The possibility of developing an eating disorder is also a symptom of borderline personality, displaying that the two disorders can go hand-in-hand with one another. Other mental illnesses that can be connected to bulimia nervosa are multiple personality disorder and

Ovulatory cycle effects on tip earnings by lap dancers Essay The empirical article ââ¬Å"Ovulatory cycle effects on tip earnings by lap dancers: economic evidence for human estrusâ⬠, [Myler, Tybur and Jordan, Evolution and Human Behavior 28 (2007) 375 ââ¬â 381] examines whether human estrus was really ââ¬Å"lostâ⬠during evolution. The estrus refers to estrous (or oestrous) cycle that comprises the recurring physiologic changes induced by reproductive hormones in most of mammalian females with a placental reproductive system. Humans undergo a menstrual cycle instead and it is believed by many theorists that human estrus has been lost during evolution. The authors have used an economic model that analyzes the effects of estrus on tip earnings by lap dancers. Typically males of a mammalian species are more solicitous towards a female of the same species. The hypothesis of existence of human estrus is sought to be proved by higher earnings reported by lap dancers during the productive period corresponding to estrus in other placental mammalian species. Here the logical assumption is that an estrous lap dancer would receive more solicitations for private show increasing her tip earnings during estrus. Design of the experiment involved multiple observations (i. e. , tips per shift) for dancers who were nested within contraception use and crossed with cycle phase. The data gathered was used to analyze effects of cycle phase and contraception use on tip earnings using multilevel modeling. Result of the empirical work confirmed the authorsââ¬â¢ prediction that pill using and normally cycling participants would demonstrate a similar difference in tip earnings between the menstrual and luteal phases. Second prediction that cycling participants would demonstrate a larger increase in the fertile phase relative to the other phases than pill-using participants was also confirmed by the findings. Experiment found strong ovulatory cycle effects on tip earnings moderated by whether the participants were normally cycling. This path breaking paper provides the first direct economic evidence for the existence of estrus in contemporary human females. Real consumer spending patterns reveal human preferences more reliably than verbally stated judgments do. This is particularly true for socially stigmatized products such as pornography or sex work. The experiment involved only 18 participants which can be considered a relatively small size for an experiment with such vast conclusions. But the small size was adequately offset by an observation period of three months and a sufficiently large number of shifts for which observations were recorded. Moreover, the tip earnings of lap dancers are a result of changes in behavior pattern of a much larger number of their clients who were influenced by the estrous state of the lap dancer. When women and men interact intimately over the course of several minutes through conversation and body contact, women apparently either ââ¬Å"signalâ⬠or ââ¬Å"leakâ⬠cues of their fertility status, and these cues influence spending patterns by male consumers. These results argue against the view that human estrus evolved to be lost or hidden from males. Logical next step, despite its difficulties, would be further research to clarify whether women have evolved special adaptations to signal estrus through such cues ââ¬â or whether the cues are ââ¬Å"leakingâ⬠to sexually discriminating men as unselected side effects of cycle physiology.

A COUNTRY BOY CAN SURVIVE :: essays research papers
When the question ââ¬Å"what consitutes a redneck?â⬠is asked the variety of answers is astonishing. People think of rednecks as drunkards, racist, trashy, or even Monticello people. I have lived in Monticello for sixteen years and even though most people are rednecks, not all. We chose Monticello to do our research because it was exactlly the atmosphere we were looking for. In order to be a redneck here, there are a few traits you must have, such as: a big truck, love the rebel flag, and dress the right way. A big truck doesnââ¬â¢t necessarily mean a nice truck. Most guys around here drive old, ragged, broke down trucks. The most common truck would be an older F-150ââ¬â¢s, a Chevy Z-71, or a Toyota Tacoma. Most trucks will also have four wheel drive, this comes in handy when you go muddin and get stuck. Many of the newer nicer trucks have bigger tires, dual exhaust, a brush guard, and a lift kit. In Monticello, you are identified by your truck. Everyone knows who everybody else is by what they drive. Most rednecks are seen as racist and prejudice against african americans. People think this because rednecks are known for their love of the confederate flag. The confederate flag is a sign of heritage in the south. It stands for what we are and where we come from. On our survey of fiftty people 73 percent agreed that the confederate flag was a sign of heritage and not hate. Another trait that constitutes being a redneck would be the way that you dress. Rednecks can be identified by their tight wrangler jeans, Dixie Outfitter shirts usually sporting a hutin, fishin, muddin logo, boots and a cowboy hat. The majority of rednecks will drink, usually Natural (nasty) light or Bud Light. They also smoke or dip, usually Marlboro reds, or lights, and Copenhagen. Most people wonder what on earth is there to do in such a small town such as Monticello? Well, there are three main things: 1. Huntinââ¬â¢ 2. Fishinââ¬â¢ 3. Muddinââ¬â¢. Although the typical weekend would include Huntin in the morning, fishin in the afternoon and muddin at night we do manage to go to at least one movie every once in awhile. Most of the guys have just recently taken to shootin pool, I am terrible at the game therefore I sit and watch most of the time. Along about early November through late February every male above the age of 12 can be found in a deerstand at 5 a.m.. The idea of sitting on a wooden platform for

Ensuring People Support for Education and Training Programs Essay
A collaborative effort is a key to success in the field of continuing education.à That is to maintain partnership with the learners, the supervisors and, the managers.à To ensure support from each participant it is important that there is connectivity before, during, and after the training program.à After all, learning is effective when it is applied as well as teaching is assimilated when it is explained. In Cafarellaââ¬â¢s book, the five primary purpose of education was explicitly stated that is; ââ¬Å"to encourage growth, to assist with practical problems, to prepare people for current and future opportunities, to assist with change for desired results, and to examine community or social issues (Schultz, 2002).â⬠à à à à à à à à à à à Educators are tasked to elaborate from the beginning the reason of the training program and if it is presented to learners as useful and not mandatory support from the learner is ensured even from the start of the program.à Key people or the supervisors can be invited in the planning process so that they can tell the planner or the educator actual experiences on how the knowledge will be applied.à Also it is best to include the supervisors in giving decisions on when is the training program be scheduled so that critical schedule in their operations will not be hampered. à à à à à à à à à à à During trainings learners should get involved in the discussion by inviting them to give examples and with those actual situations mentioned by the participants, trainers should help the learner to reflect on the subject and how it could be applied.à Supervisors at the same time can be asked to mentor or assist in the on-going program. à à à à à à à à à à à Training program does not end at the venue but probing whether the learning process is blocked after instruction was given ensures effectiveness of the course.à Learners should be encouraged to help one another and evaluate the learning process. à Supervisors should be asked on the feedback if the course has been effective by checking if what is learned was applied in each participants actual work situation.à To ensure continuous support and partnership, endings should be addressed whether it is positive or negative (Caffarella, 2002). à à à à à à à à à à à Managers are tasked to implement goals and objectives; they are the one who manage change.à To ensure their support from beginning to end, they should be asked to provide consultations before and after.à They should be convinced that the program is helping their organization to grow.

Multilingualism or Not? Essay
Today in America, there is a raging debate going on: should we promote multilingualism or accept a ââ¬Å"melting potâ⬠ideology? The melting pot ideology dictates assimilating into a common culture and language. Views on this issue are very polarized, which make a compromise seem hard to accomplish. Two articles that pertain to this topic are ââ¬Å"American Multilingualism: A National Tragedy,â⬠by Franklin Raff published on WND.com, and ââ¬Å"English Only Laws Divide and Demean,â⬠by Warren J. Blumenfeld published in The Huffington Post. Both articles are direct contradictions of each other with Raff saying languages other than English are unduly practiced and embraced in America while Blumenfeld argues that America should promote the practice of multiple languages. While I do not find myself agreeing completely with either one, there are points in both that appeal to me and give me a better understanding of multilingualism, and the influences of its wide reaching effects on society. In ââ¬Å"American Multilingualism: A National Tragedy,â⬠writer Franklin Raff introduces an ad broadcast on Super Bowl Sunday. It is a Toyota car ad, which is touted to be the first ââ¬Å"bicultural, bilingualâ⬠advertisement. The spot compares the benefits of being bilingual to a hybrid car. Raff claims that the ad agency responsible for the ad has bluffed in equating bilingualism to anything good. He even goes as far as to say that the effects of promoting bilingualism can be fatal. To support his claim of fatality he uses the situation in where doctors are unable toà comprehend their patients. He also brings up the fact that workers who are unable to comprehend safety regulations at worksites meet untimely deaths. Raff speaks of the Chicago school system, which has an overwhelming population of Hispanics and is also the worst performing of all school systems. He then introduces a janitor, who cannot speak English and as such cannot get a better job despite his attention to detail, and a little Spanish speaking girl, who he encountered in the supermarket and cannot offer her help due to her not understanding English. Raff also provides statistics that portray Hispanics as unable to complete higher education courses due to their knowledge of Spanish and not English. He closes by saying it is a disservice to oneself to speak Spanish and as such it is a national tragedy. Raffââ¬â¢s article has a feeling of immense passion on something he feels is a great plague to the nation. He argues to great lengths on the extent of ââ¬Å"damageâ⬠that speaking other languages causes to society. The Spanish language is his argumentââ¬â¢s main adversary. He uses rhetorical strategies such as pathos and angle of vision to significant effect to support his claim. In his attempt to gain emotional support from his readers he makes impassioned pleas and relates personal experiences. He introduces the idea of being unable to comprehend languages as being detrimental to the point of even causing deaths. He uses examples of miscommunication in a health care facility and safety regulations at work sites. Death being the worst fate of mankind is a useful point for Raff as readers would be appalled that death is a possibility for some and that it could be avoided. He also speaks of the failing Chicago school system which is densely populated by Hispanics and he insinuates that their practice of language is what fails them. Others he says afflicted by speaking Spanish include a janitor he knows and a girl he encounters at the supermarket. Raff seeks to gain support by relating the troubles he perceives and leadingà people to believe that Hispanics would be afforded a better quality of life and possibility of success by relinquishing the Spanish language and adopting the English language. Franklin Raffââ¬â¢s use of angle of vision lies in subtle inferences that readers have to make on their own. As it relates to the janitor he describes as a ââ¬Å"fast, meticulous and good-natured worker,â⬠Raff claims he can communicate with the janitor due to his knowledge of Italian, but Raff fails to write about the janitorââ¬â¢s feelings but rather what he believes the janitor should feel. Raff also speaks of high failure rates of Hispanics but he fails to account for any success of Hispanics in America, by doing this he can gain support from people who do not choose to consider more factors than the ones only stated by Raff. He makes it seem as though it is all doom and gloom because of knowing another language. In ââ¬Å"English Only Laws Divide and Demean,â⬠Warren Blumenfeld starts by relating an experience he had with his multilingual cousin, living in Belgium. His cousin poses a riddle to him, with the outcome saying that persons that can only speak one language are referred to as ââ¬Å"US-Americanâ⬠as opposed to monolingual. Blumenfeld accepts this as a truth and goes on to lament that despite being so closely bordered by countries that speak other languages, Americans are stuck in their monolingual ways. He states that Americansââ¬â¢ lack of care for other languages has been endorsed by major political figures such as former President Theodore Roosevelt and Senator Rick Santorum. The ideas that there has been a campaign to make English the ââ¬Å"officialâ⬠language and that laws have been proposed to outlaw other languages are slammed by Blumenfeld, who states he has even started a petition against this movement. He also uses a personal experience of a friend of Mexican descent, who as a child was berated and punished for making an exclamation in Spanish at school. Blumenfeld states that this prejudice is a violationà of democracy and no true patriot could support it. He proclaims that Americaà should embrace its rich diversity and shed its ââ¬Å"melting potâ⬠ideology if it is to become a beacon to the world. Warren Blumenfeld in his attempt to gain the support of his readers employs the use of appeals to emotions and values. In his retelling of his encounter with his cousin he seeks to make Americans, including himself, feel as though they have not done enough to embrace linguistic diversity. By doing this he is able to make Americans feel t hat they should work assiduously to overcome this rather true stereotype. He also speaks of the extent American society will go to eliminate other languages, including campaigns by political leaders and proposition of laws. By highlighting these details and framing them in such a way that depicts them as promoting ignorance, Blumenfeld is able to gain the readersââ¬â¢ support. To show just how serious and credible his claim is, Blumenfeld then identifies that he has started a petition, which encourages readers to a call to action. To then gain the readersââ¬â¢ sympathy Blumenfeld uses an experience from a friend who as a child was castigated for speaking Spanish. This experience causes readers to be appalled that in their society, people, especially children are being chastised because of their cultural differences. The highpoint of Blumenfeldââ¬â¢s argument is introduced near the end when he begins to speak about the founding principles of America. He proclaims that the values of democracy and diversity are woven into the fabric of the nation and its people, and as such the people should work to protect and propagate these American values. True American patriots would then see the issue of multilingualism as an important part of the great nationââ¬â¢s future. In terms of a comparison between both articles, the only similarities lie in both writersââ¬â¢ use of rhetorical appeals and angle of vision. Both writers rely heavily on the emotional and value appeal of pathos to connect with their readers. The difference between both articles is the ideology of the authors. The authors directly contradict each other. Franklin Raff would haveà Americans believe that the practice of languages other than English can leadà to death and failure. On the other hand, Warren Blumenfeld implores Americans to embrace learning and practicing other languages as it allows people to communicate across borders easily. After reading and analyzing both Franklin Raffââ¬â¢s and Warren Blumenfeldââ¬â¢s articles in detail I was able to gain new knowledge on the subject of multilingualism. From personal experiences I previously had opinions on the topic but from my newly attained knowledge I was able to strengthen my opinions. The basics of my ideology are that I believe that all government and other official documents should be printed in one language, most suitably English, for ease of communication. Though we should also encourage people to learn and practice multiple languages as that ability enhances a personââ¬â¢s effectiveness to themselves and to society as a whole. I was fortunate to be raised in a society that promoted learning multiple languages, though English was my native tongue. I learnt the fundamentals of both French and Spanish up until the 8th grade in Jamaica. Now I can read and write both languages at a level I perceive to be fair, which is something I am proud of. Though I lack in speaking fluency of these languages I plan to eventually become fluent. After 8th grade I moved to Florida. There I was surprised to know that my new peers had no foreign language course after the 5th grade and then they would only have a two-year crash course in high school. Having had that two-year crash course as well, I felt that it was more about getting a grade rather than learning to appreciate and comprehend the language. On the other hand, the peers I left in Jamaica went on to learn either one or both languages at a higher level. In America, I believe middle and high schools should operate a continuous curriculum for foreign languages as it will enhance studentsââ¬â¢ abilities. Franklin Raff in his article claims that Hispanics have a higher failure rate at school, particularly in Chicago, because of their knowledge of another language. Having had Hispanic classmates I am in complete disagreement withà Raff as it was apparent they were just as inclined for success and I believed that their ability to speak both English and Spanish gave them somewhat of an edge in being successful. As it pertains to the Chicago school system there is likely to be social factors other than language, including poverty in a densely populated area, that can lead to higher failure rates that Raff fails to account for. I also disagree with Warren Blumenfeld that English should not be made the official language of America and that government documents should be printed in multiple languages. Blumenfeld states that it is unnecessary to make English the official language but I believe not making English the official language is just as unnecessary. America unlike many other countries that promote multilingualism, does not have an official language. Having an official language does not mean that a country ignores other languages. In Jamaica, English is the official language but foreign languages are given great emphasis in the education system. For American governments to reduce spending, printing long documents in English only would be a good idea, but smaller statements such as safety information on airplanes can be printed in multiple languages, including French and Spanish. Though I have disagreements with the points the writers make, I do find some common ground with them. Franklin Raffââ¬â¢s claim that different languages make communication between people difficult is very understandable. There have been a few instances where Iââ¬â¢ve heard people say they could not communicate with people at places such as the gas station as one person solely speaks English and the other solely Spanish. To achieve goals and make things happen require effective communication between people. I also agree with Blumenfeld that promoting Williamsà multilingualism creates a better global society. I believe people should attempt to learn and appreciate other languages as it is a show of competence and facilitates good relations among different groups of people. America, in particular, has a few negative connotations around the world, and I believe if we as a people can embrace other cultures and languages America will gain a deserved mutual respect. As the topic of multilingualism holds great significance to me, I found it imperative to explore the writings of both Franklin Raff and Warren Blumenfeld. Both articles related interesting and contrasting ideas on the topic. As seen with my agreements and disagreements it is best to only consider the ideas rather than accepting any one as the truth. In my opinion, the importance of communication cannot be overstated, as it is a component of progress. While one language makes such communication easy, diversity among the worldââ¬â¢s citizens cannot be eliminated and as such governments should encourage acceptance of other societiesââ¬â¢ diversities and languages. It starts with education, to facilitate students to learn and gain appreciation for other languages and create a more connected world.

Cognitive Dissonance Essays - Social Psychology, Psychology
Cognitive Dissonance Essays - Social Psychology, Psychology Cognitive Dissonance Cognitive Dissonance How do human beings make decisions? What triggers a person to take action at any given point? These are allquestions that I will attempt to answer with my theoretical research into Leon Festingers theory of cognitive dissonance, as well as many of the other related theories. We often do not realize the psychological events that take place in our everyday lives. It is important to take notice of theories, such as the balance theory, the congruency theory and the cognitive dissonance theory so that ones self-persuasion occurs knowingly. As psychologist and theorist gain a better understanding of Festingers cognitive dissonance theory manipulation could occur more easily than it already does in todays society. Leon Festingers cognitive dissonance theory is very closely related to many of the consistency theories. The first of the major consistency theories, the balance theory, was proposed by Fritz Heider (1946, 1958) and was later revised by Theodore Newcomb (1953) (Larson, 1995). Heider and Newcombs theory was mostly looking at the interaction between two people (interpersonally) and the conflicts that arose between them. When two people have conflicting opinions or tension is felt between another person, it is more likely persuasion will occur. Because if no tension was felt between the two parties, or there were no conflicting opinions there would be no need to persuade each other. If you think about it persuasion occurs only because there is tension between two facts, ideas or people. Charles Larson writes in his book, Persuasion, Reception and Responsibility, another approach to the consistency theory is congruency theory, by Charles Osgood and Percy Tennenbaum (1955) (p.82). This theory suggest that we want to have balance in our lives and there is a systematic way to numerically figure it out. When two attitudes collide we must strive to strike a balance between the two attitudes. The balance varies depending on the intensity we feel about each attitude and our pre-disposed positions concerning the attitude. We either have a favorable , neutral or unfavorable opinion concerning ideas. When two attitudes collide we will attempt to downgrade the favorable position and upgrade the unfavorable position so that we feel a balance. For example, suppose someone thought of Mel Gibson as a good role model. Later on they come to find out Mel Gibson does not like football. If the person was to like both football and Mel Gibson one of three things would happen: 1) The individual would downgrade their opinion of Mel Gibson, or 2)downgrade football, or 3) downgrade both. The action taken would create psychological consistency in ones mind. These theories are very interesting and have been quite researched, but none more so than Leon Festingers theory of cognitivedissonance. Leon Festingers theory, unlike the others I have described, deal with quantitative aspects, as well as qualitative. Thats what is so different and revolutionary about Festingers theory. Robert Wicklund and Jack Brehm (1976), in their book Perspectives on Cognitive Dissonance, write, Most notably, the original statement of dissonance theory include: propositions about the resistance-to-change of cognitions and about the proportion of cognitions that are dissonant, both of which allowed powerful and innovative analyses of psychological situations (p.1). The term dissonance refers to the relation between two elements. When two elements do not fit together they are considered dissonant. Cognitive dissonance can be broken down into a number of elements. As Brehm and Cohen (1962) write, A dissonant relationship exist between two cognitive elements when a person possesses one which follows the obverse of another that he possesses. A person experiences dissonance, that is, a motivational tension, when he (or she) has cognitions among which there are one or more dissonant relationships (p.4).Cognitive dissonance can occur intrapersonally as well as betweentwo or more people. With individual cognitive dissonance the individual longs for consistency within their own mind. Second, there exist dissonance between two or more people. This occurs when two people have differing opinions about a particular issue.This phenomenon may have something to do with varying degrees of knowledge about the issue or different belief systems being enacted. An example of this can be seen by taking a look at the cultures of the West versus cultures of the East. Cultures of the East value loyalty and honor. Cultures of the West have different value systems that often collide with those of the East. Between two parties, dissonance may arise from: (1) logical inconsistency; (2) because of cultural mores: (3) because of a specific opinion; and (4) because of past experience. To reduce cognitive dissonance a person

A Hyphenation Quiz
A Hyphenation Quiz A Hyphenation Quiz A Hyphenation Quiz By Mark Nichol Yes, I hype correct hyphenation, but proper treatment of the little line enables clear communication, so on this site, I repeatedly attach importance to the attachment tool. In the following sentences, excessive or insufficient use of hyphens clouds rather than clarifies. Correct the connective calamities below, then check my answer key at the bottom of the page: 1. ââ¬Å"The program offers student-directed and student-initiated research- and discovery-based learning opportunities.â⬠2. ââ¬Å"The plan includes accidental death and dismemberment coverage.â⬠3. ââ¬Å"The businessman-turned-candidate spoke about his religious beliefs.â⬠4. ââ¬Å"Maybe the country just doesnââ¬â¢t want a my way or the highway Texan in the White House again.â⬠5. ââ¬Å"Travel to near-space in a 400-foot diameter balloon.â⬠6. ââ¬Å"He all-but-lectured the lawmakers assembled.â⬠7. ââ¬Å"The rainbow flag flew at half-staff to honor Elizabeth Taylor, the Hollywood-star-and icon to gays who died in March.â⬠Answers 1. This hyphen-saturated sentence, though technically correct (though to be fair but awkward, the second mention of the word student should be elided), reads better when it is relaxed: ââ¬Å"The program, based on research and discovery, allows students to direct and initiate their own learning opportunities.â⬠ââ¬Å"Student-directed and -initiatedâ⬠and ââ¬Å"research- and discovery-basedâ⬠are proper examples of suspensive hyphenation, but the double-suspension string ââ¬Å"student-directed and (student)-initiated research- and discovery-basedâ⬠is excessive. 2. As written, this sentence implies that the coverage is accidental. But the coverage presumably protects against two possibilities: accidental death, and dismemberment, so the phrase ââ¬Å"accidental deathâ⬠should be hyphenated to signal that the constituent words combine to modify coverage, and because the insurance also applies to nondeliberate dismemberment, that word should be preceded by a suspended hyphenation. However, because no insurance company hyphenates this phrase in its literature, Iââ¬â¢m inclined to request, as in the previous example, at least a relaxed rewrite that obviates hyphenation: ââ¬Å"The plan includes coverage in case of accidental death and dismemberment.â⬠3. When the verb turned stands between a word describing a former state and one referring to a current state, unlike as is the case with the similarly employed conjunction cum (ââ¬Å"withâ⬠), no hyphenation is necessary: ââ¬Å"The businessman turned candidate spoke about his religious beliefs.â⬠4. The word string defining what kind of Texan the subject is must be corralled into one group, either with quotation marks that imply that the sentiment is literally or figuratively stated, or with multiple hyphens: ââ¬Å"Maybe the country just doesnââ¬â¢t want a my-way-or-the-highway Texan in the White House again.â⬠5. This sentence manages two hyphenation errors within its ten-word length. Near is often erroneously attached to the following noun; hyphenation is correct only when near and the following word form a phrasal adjective modifying a third term, as in ââ¬Å"near-space tourist travelâ⬠(where the open compound ââ¬Å"tourist travelâ⬠is an noun phrase). Also, the half-hearted hyphenation that follows implies the existence of an odd item referred to as a diameter balloon; this one apparently has 400 five-toed appendages. The phrase should be revised to correctly reflect that the balloon is 400 feet in diameter: ââ¬Å"Travel to near space in a 400-foot-diameter balloon.â⬠6. The modifying phrase ââ¬Å"all butâ⬠needs not be attached to the verb, nor do the two words in that phrase require connection: ââ¬Å"He all but lectured the lawmakers assembled.â⬠7. Half-staff, like its synonym half-mast (often erroneously used in nonmaritime contexts), is correctly hyphenated. The hyphenation error occurs later in the sentence, when the writer, confused about how to construct the gloss of Elizabeth Taylor, loses steam near the end. The phrase ââ¬Å"Hollywood star and icon to gays,â⬠however, requires no connective tissue: ââ¬Å"The rainbow flag flew at half-staff to honor Elizabeth Taylor, the Hollywood star and icon to gays who died in March.â⬠Want to improve your English in five minutes a day?

Questions for thought - Assignment Example It defines the kind of content that should not appear in the messages and the rights of the recipients. However, these laws have only been partially effective. As such, users have resorted to alternative means of preventing spams with an example being the use of the anti-spamming techniques embedded in products and software. In the current business setting, it is common to find enterprises allowing their employees to use their personal devices in their places of work to carry out work related duties. This practice, however, raises two major concerns, which include the privacy of information and misuse of company data. In order to ensure that the practice benefits the company rather than having detrimental effects, there is a need to have standards of practice in place. These will define the kind of device that can be used, how they are to be used and who can use it (Heary and Woland 56). In addition to this, employees should have specific credentials that allow them to access information. Finally it is imperative to ensure that the devices are only used to access information and not for storage purpose. This will prevent the material from reaching the wrong hand should the devices get lost. Cloud computing is a technique whereby by a group of remote servers and networks are used to facilitate storage of data in a central location. The data can then be accessed online by the company using the services (Voorsluys, Broberg and Buyya 23). This technology allows an organization to use computer systems as a utility rather than building their own infrastructure. It has been incorporated in several business practices, with the outcome being that it has freed the IT team from the duty of building or maintaining a computing infrastructure for the company. In addition to this, it has allowed the end users to spin up the existing computing resources without requiring the intervention of the IT

Principles of Economics - Research Paper Example sgruntling customers, suppose that the company may introduce a different type of programming that is cheaper for the company to provide yet is equally appealing to customers. Explain what would be the effects of this action. The law of demand states that, ceteris paribas, the higher the price of a commodity, the less the demand will be. On the other hand, the law of supply states that, all factors being constant, sellers are more willing to supply goods at a higher price than at a lower price. This theoretical point at which sellers are willing to supply goods and buyers are getting all the commodities they are demanding is referred to as the equilibrium. The equilibrium is depicted in the figure below: Figure 1: Market equilibrium chart (ââ¬Å"Economics Basics: Demand and Supply,â⬠2011) If the government make a price ceiling law on cable TV that sets the price below the current equilibrium price two things will happen immediately: (1) cable TV sellers will find the business less attractive because of increased possibility of lower revenues and thus they will lower their supply. (2) Consumers will find the lower prices attractive and thus they will increase their consumption and demand for cable TV. After some duration, the huge consumer demand and low supply will cause consumers to compete for the few cable TVs available. This is depicted below: Figure 2: Effect of price ceiling (Taylor, 2006) In a free market economy, the consumer competition for cable TVs will push the prices up, which will make sellers want to supply more and hence bring the price closer to its equilibrium. However, in this case, the price ceiling prevents suppliers from increasing the supply because of the low marginal benefits compared to marginal cost of supplying cable TVs. This eventually... The rationale for releasing the new guidelines to be used by the Department of Justice and the Federal Trade Commission for evaluating proposed mergers is to provide more clarity and transparency to businesses seeking to engage in mergers and acquisitions. This way business can tell beforehand whether they will be successful with their application or not. Additionally, the new Guidelines take into account changes that have taken place in the legal and economic arenas since the last revision in 1992. From the guidelines one thing that stands out is the Department of Justiceââ¬â¢s and the Federal Trade Commissionââ¬â¢s focus on protecting competition and innovation within the American business sector. Mergers and acquisitions that may substantially lower competition, or to tend to create a monopoly will be rejected. So too will those M&As that are viewed as done to kill innovation. Some of the major implications of these guidelines are that: (1) it will enable companies save on r esources that they may have wasted on a merger or acquisition that ends up being disapproved; and (2) it provides the legal fraternity with more clear guidelines for those who would like to seek legal redress

The case of Radmacher v Granatino Essay Example | Topics and Well Written Essays - 2250 words
The case of Radmacher v Granatino - Essay Example Center of discussion in this paper is the case of Radmacher v Granatino that has drawn much attention because the High Court will be finally deciding how much weight it would place on the pre/ante-nuptial agreement in the area of financial relief during divorce. Pre-nuptial or ante-nuptial arrangement is typically sought by rich families, as in the case of Radmacher formerly Granatino v Granatino, to protect and preserve the assets of the wealthy party from a claim during divorce. The terms are typically spelled out on how their assets be divided or waiver of claim through a written agreement. Pre-nuptial or ante nuptial however is traditionally viewed by English law as non-binding because it is contrary to public policy. English Courts however have discretion to how to treat ante-nuptial agreements, on what weight should be placed on them and has the power to veer away from what was agreed on the ante-nuptial arrangement. This is especially so when there are children borne out of a long marriage. There are also other circumstances when the Courts could reinterpret or set aside the ante-nuptial agreement from its original arrangement in cases where there is an indication of duress on the weaker party to agree, may cause unfairness to one party, non full disclosure of assets, or where the parties involved was not able to get independent counsel on the various implications of the ante-nuptial arrangement before entering into the agreement.... The husband was a French national and the wife is a German national. The ante-nuptial agreement was signed three months before the marriage under German jurisdiction and specified that each party will keep their assets and that the other party will make no claim against the assets of the other in the event of a divorce. The wife had considerable wealth and inheritance before the marriage while the husband was a banker at the time the agreement was signed. The husband did not have an independent counsel about the implication of the ante-nuptial agreement. The agreement also contained no provision in the event that their marriage will have children. They were married in London in 1998. After eight years of marriage, the appellant and the respondent separated. Their marriage produced two daughters. During the dissolution of their marriage, the husband embarked on a research studies and had left his job as a banker and applied to the court for financial relief. The High Court then decide d to grant him over ?5.5m which would enable him to have an annual income of ?100,000 for life. He was allowed to have a home in England so that his children could visit him. The wife appealed to the Court of Appeals where it was decided in favour of her to give weight to the ante-nuptial agreement where the financial relief should only be limited on the provision of him being a father and not for his own need. The husband then appealed to the Supreme Court. Decision Traditionally, English Courts do not put considerable weight to agreements between individuals who were getting married or already married4 (post-nuptial agreement) that specifies the contingency or terms of their separation on the grounds that this may encourage them to separate5.

The Strong Nuclear Force | Essay
The Strong Nuclear Force | Essay Youssef El Laithy One of the most extraordinary simplifications in physics is the fact that only four distinct forces are responsible for all the known spectacles that go on in the universe. These four basic forces are the electromagnetic force, the gravitational force, the weak nuclear force and the strong nuclear force. Since the weak and the strong force act over an extremely short range, (less than the size of a nucleus), we do not experience them directly. Even though we donââ¬â¢t directly experience these forces they are vital to our existence. These forces determine whether the nuclei of certain elements will be stable or will deteriorate, and they are the basis of the energy release in many nuclear reactions. The forces determine not only the stability of the nuclei, but also the abundance of elements in nature. The properties of the nucleus of an atom are determined by the number of electrons the atom has. The number of electrons in an atom, therefore, determines the chemistry of the atom. The gravitational force is responsible for holding together the universe at large, the atmosphere, water, and us; humans, to the planet. The electromagnetic force governs the atomic level phenomena, binding electrons their atoms, and atoms to other atoms in order to form molecules and compounds. The weak nuclear force is responsible for certain types of nuclear reactions. The fourth and last force, the strong nuclear force is responsible for holding the nucleus together. The Strong Force is also one of the four fundamental forces of nature, experienced by particles called quarks and sub particles made up of quarks. It is theforce that causes the interaction responsible for binding and holding protons and neutrons together in the atomic nucleus of a given element. The strong force is the strongest of among all the other forces forces, being approximately 100 times as strong as the electromagneticforce. It has the extremely short range to which it has an effect. A range of approximately 10^-15 m, less than the size of the atomic nucleus. The strong force is carried by particles called gluons; that is, when particles interact through the strong force, they do so by exchanging gluons. The protons in a nucleus must experience a repulsive force from the other protons in the nucleus.This is where the strong nuclear force comes into play. The strong nuclear force is created between the nucleons (protons and neutrons) by the exchange of particles called mes ons. This exchange can be compared to constantly hitting a tennis ball or a footballback and forth between two people. As long as these particles (mesons) are in motion back and forth, the strong force is able to hold the participating nucleons together. Thenucleons, however; mustbe extremely close to each other in order for this exchange of mesons to occur. The distance requiredfor the force to take place and have an effectis roughly about the diameter of a proton or a neutron. Thus, if a proton or neutron can get closer than this distance to proton on neutron, the exchange of mesons occurs normally and the force has an effect. However,if they cant get that close, the strong force is too weak to make them bind together and thus the force wonââ¬â¢t have an effect and the nucleus would rapture. The range of the Strong Force varies from where it takes place. The strong interaction is apparent in two areas: On a large scale (about 1 to 3 femtometers ), it is the force that binds protons and neutrons (nucleons) together to form the nucleus of an atom . On a smaller scale (less than about 0.8 femtometers, the radius of a nucleon), it is the force (carried by gluons ) that holdsquarkstogether to form protons, neutrons, and other hadron particles. The discovery of the Strong of the nuclear force was a remarkable discovery and cleared up lots of mysteries that haunted many physicists in this era. The discovery force wasnââ¬â¢t all at once; meaning that the discovery was based on the work of more than once scientist and physicist all over the years. The first discovery was by James Chadwick. In 1932, British physicist James discovered that the nucleus of atoms contain neutrons. Soon after this discovery, the American-Hungarian physicist, Eugene Wigner suggested that the electromagnetic force wasnââ¬â¢t the force responsible forholding the nucleus together and he also suggested that there are two different nuclear forces not just one.Later on,In 1935 Japanese Yukawa Hideki reasoned that since the strong nuclear force and weak nuclear force had never been noticedor observed by the bare eye or even by microscopesthey must act over a range smaller than the diameter of the atomic nucleus.Yukawa developed the first field theory ofthe strong force with a new particle he called mesons as the force carryingsimulated particle. From these facts and hypothesizes, Hideki Yukawa concluded that there exists a force that binds nucleons (protons and neutrons) together. He named the force the ââ¬Å"strong nuclear forceâ⬠because it had to be stronger than the electromagnetic force that would otherwise push the nucleons apart. In everyday life and our day to day life, were only aware of two fundamental forces: gravity and electromagnetism. Physicists know about two more forces, which are carried out within the atom itself (inside atoms): the strong nuclear force and the weak nuclear force.Try and imaginetwo protons (positive charge), they are pulled together by the strong nuclear force (as long as they are within range to start with). But the electromagnetic force pushes them away from each other, because they both have the same positive electric charge. When we talk about the uses if the strong nuclear force we canââ¬â¢t really find a direct use in which humans use the force. The only direct use is that the binding energyrelated to the strong nuclear force is used innuclear powerandnuclear weapons. The strong nuclear force is crucial to our everyday survival, God created this force exactly to suit our survival. Following this notion two questions are raised: What would happen if the strong nuclear force were a bit weaker? If the strong force were even slightly weaker than what it is, it would not be able to hold the atomic nuclei together against the repulsion of the electromagnetic force. According to Barrow and Tipler: `Ifthe Strong Force was decreased by 50% its normal power thiswould adversely affect the stability of all the elements essential to living organisms and biological systems. A bit more of a decrease, and there wouldntbe any stable elements except hydrogen. What would happen if the strong nuclear force were a bit stronger that what it is? According to Borrow and Tipler: ââ¬Å"If the strong nuclear force was just a bit stronger compared to the electromagnetic force, two protons could stick togetherdisregardof their electromagnetic repulsion (forming a diproton).If this happened, all the hydrogen in the universe would have been burned to helium. If there were no Hydrogen in the universethere would be no water, for a start, and there would be no long-lived stars like the sun. (Stars made from helium burn up much more quickly than stars made from hydrogen).â⬠In conclusion, The Strong Nuclear force is one of the four fundamental forces found in nature. The strong nuclear force is responsible for holding the neutrons and protons in the atomic nucleus. The interactions are experienced only by particles called quarks and by elementary particles made from quarks (mesons, gluons). The discovery of the strong nuclear force was possible by the collective work of many physicists over many years. The strong force isnââ¬â¢t of that much of direct use for humans. However, the force is crucial to our everyday life. If the strong nuclear force was slightly even weaker than it is, all the chemical elements needed for life would not be stable, and we, humans, would not seize to exist. The strong force isnt of that much of direct use for humans. However, the force is crucial to our everyday life. Ifthe strong nuclear force was weaker than it is, the chemical elements needed for life wouldnââ¬â¢t be stable, and we would not be here. On the other han d, if it were even slightly stronger than it is, all the hydrogen in the universe would have been burned in the big bang. As a result, there would be no prolonged stars like the sun, and no molecules like water. There would probably be no complex chemistry in the universe, and we would not seize to exist.

The international system today is an interplay of national power of different nations. This can be felt in the emerging world order. There has been a perceptible change, particularly during the last two decades, in the manner the nation states conduct international relations. Military alliances have given way to multilateral groupings, understandings and strategic partnerships. Nations are becoming increasingly aware of the power or influence that they wield vis-à -vis other nations.à [1]à They are also looking at the ways and means to use this national power to secure their vital interests. In the later part of last century, National Power was only considered to be military power as can be understood by the superpower status of Soviet Union. But the disintegration of the Soviet empire and changing face of world relations due to economic globalization changed the world perception and brought the term Comprehensive National Power. This term was more inclusive of the overall state of the affairs of a nation and a measure of its constituents could indicate the strength and weaknesses.à [2]à National Power has tangible and intangible elements. Geography, natural resources, industrial capacity, population, military power form the tangible parts while national character and morale complete the intangibles. Indias economy has contributed in the last two decades towards a major share of the National power. In fact, India has even demonstrated certain soft power by cooption and attraction of other nations to achieve some of its aims. The primary currencies of soft power are an actors values, culture, policies and institutions. Indias soft power is based on its social and cultural values, the Indian Diaspora abroad and its knowledge base. India is being considered a knowledge superpower and is well placed to leverage its position in international relations. However, the military has also contributed towards the soft power. A well-run military has been a source of attraction, and military-to-military cooperation and training programmes, for example, have established transnation al networks that enhance countrys soft power. METHODOLOGY Statement of Problem The growth notwithstanding, India cannot afford to be satisfied with its current status. The geopolitical situation in the region is unstable. Though Pakistan has fewer options left after it has been exposed as a hub of terror activities and a haven for wanted terrorists, still if cornered by the world pressure and the internal compulsions it will not think twice in a military option against India to divert the attention and bring in its all weather friend , China, into the picture. India can achieve its national aims only if the internal and external threats to its security is ensured. This situation can be understood with an analogy to game of soccer; a team may be having the best of strikers in their forward and midfielder players, who can score goals at will, but their efforts are inconsequential if the goalkeeper is not trained and equipped to save goals from adversary. Thus, in the changing geopolitical situation, it is pertinent to evaluate the share of constituents of National Power to ascertain the future dynamics of a nations aspirations and interests and the regional environment. India has already made tremendous progress in various fields to achieve soft power constituent to contribute towards National Power. Indian economy is showing positive growth and attracting strategic partnership with leading economies around the globe.India , now needs to develop the military constituent to further pursue its National aim. Hypothesis India needs to develop a potent Military capability by the year 2025 to be able to assert its National Power in keeping with the stated National objectives. Methods of Data Collection 9. The data for this dissertation has been collected from a large number of books, periodicals, magazines, newspapers, internet and research journals that are available in the Defence Services Staff College library. The data related to Indian Military Power has been collected from open sources only so as to avoid any classified information to be brought out. The Bibliography is attached as Appendix. Organisation of the Dissertation Apart from a chapter on the introduction and methodology, the dissertation has been organized under the following chapters:- CHAPTER 2. CONSTITUENTS OF INDIAN NATIONAL POWER Section 1. National Power. Section 2. Indias National Power. Section 3. Constituents Of Indian National Power. CHAPTER 3. MILITARY POWER Section 1. Elements of Military Power. Section 2. Present State Of Indian Defence Forces. Section 3. Defence Budget And Modernisation Program. CHAPTER 4. SHORTCOMINGS OF INDIAS MILITARY POWER Section 1. Analysis. Section 2. Intra Organisaton Level. Section 3. Shortcoming As A National Instrument. Section 4. Recommendations . CHAPTER 5. DESIRED NATIONAL POWER BY 2025 Section 1. Geopolitical situation and regional environment In 2025. Section 2. Indias Predicted Growth By 2025. Section 3. Desired National Power. Chapter 2- Examining the constituent of Indian National Power. The present Indian standing in the world order is based on the soft power developed and the economic growth achieved by India. India as rising economy, offers excellent investment opportunity to the world. The democratic form of governance also projects India as stable and secure investment site in the long run. However we need to examine the constituents and their present share towards National Power. Chapter 3- Military Power. It itself comprises the tangibles and the intangibles. It can be broadly categorized in force capability and force employment. There has been a change in war fighting. The technological advancement ,weapon lethality, destructiveness and precision along with the information frontier has increased the cost factor of going to war. Thus there is a need to analyse the military power constituents to understand the importance towards national Power. Chapter 4- Analysis and Short comings of Indian Military Power. To suggest steps towards projecting a stronger military power the present capability needs to be analysed and the shortcoming to be highlighted. Chapter 5- Desired National Power by 2025. The regional environment in the near future entails proactive approach by India to project comprehensive national power to have secured borders and assured growth to achieve its national aims . CHAPTER 2 CONSTITUENTS OF NATIONAL POWER National Power 1. The international system today.is an interplay of national power of different nations. There has been a perceptible change.in the manner the nation states conduct International relations. Military alliances have given way to multilateral groupings, understandings and strategic partnerships. Nations are becoming increasingly.aware of the power or influence that they weild.vis-à -vis other nations. 2. During 1960 and 70s most theorists.doing research on international relations avoided dealing.with phenomenon of power. National power was considered synonymous.with military power. This would explain to a great extent the superpower status.of erstwhile Soviet Union and its unexpected disintegration. Since then perception of national power.has undergone a change. It is called as comprehensive National power by the theorists which is a more inclusive term comprising all the facets of a nations resources which contribute towards its security. Defining National Power 3. National power is the ability of a nation with the use of which.it can get its will obeyed by other nations. It involves the capacity to use force.or threat of use of force over other nations. With the use of national power, a nation is able to control.the behavior of other nations in accordance with its own will. In other words, it denotes the ability of a nation.to fulfill its national goals. It also tells us how much powerful or weak.a particular nation is in securing its national goals. Basic Elements Of National Power 4. The basic elements of national power include diplomacy, economics, informational, soft power and the age old trustworthy element of military power. It can also be classified as comprising of tangible elements and intangible elements. Geography, natural resources, industrial capacities, population, military power form the tangible elements of national power and national character and morale complete the intangibles. Indias National Power 5. In international politics, the image of India till recently used to be in terms.of its perennial rivalry with Pakistan and as power confined to South Asia only. However, as result of the remarkable improvement.in Indias national strength over the last decade, consisting of.its hard and soft powers, the world has started rehyphenating India.with a rapidly growing China. The term rising India is a buzzword in the International Relations discourse nowadays. Indias national power has begun to rise steadily.since Pokhran-II. India unleashed a slew of path-breaking initiatives.in quick succession in 1998 (and beyond). It was from this year onwards that the idea of India being a great power,.first floated by Nehru, started to be reflected in its foreign policy. Admittedly, India shifted its foreign and economic policies.soon after the end of the Cold War in 1991 when it started broadbasing.its diplomacy, initiated economic reforms by dismantling the economic model.based on import substit ution, and went for market friendly policies. The economic reforms did give India economic stability.in the sense that India started growing at 6% annually.ever since the economic liberalization of early 1990s, however, political stability remained fragile. The country got much-needed political stability.at the center in March 1998 and a series of radical initiatives in quick succession beginning with the nuclear tests in the Pokhran desert of Rajasthan on May 11th and 13th 1998, was a grand strategic masterstroke by independent India. India initiated Multi-aligned/Great power diplomacy.for the first time in its independent history when it developed strategic partnerships.with all the great powers simultaneously, especially its relations with the United States and Japan, while retaining time-tested ties with Russia. India made institutional arrangements to its national security.when it set up the National Security.Advisory Board, National Security.Council, Nuclear Command Authority, developed a.nuclear doctrine, and so on. 6. More importantly, India developed a much needed strategic vision.whereby it redefined its geo-strategic.construct well beyond the mainland of South Asia. The comprehensive geo-strategic.construct included the Indian Ocean, the Middle East, Central Asia and the Asia-Pacific. In fact, the 1998 nuclear tests themselves were indicative of the fact that India had begun to appreciate the role of hard power in securing its national interests and also in making her influence heard in international politics. 7. The India, that China defeated.in 1962 was guided by a foreign policy canon of non-alignment.vis -à -vis the superpower enmity, and it remained the cornerstone of Indias international.diplomacy for more than four decades. However, this foreign policy paradigm underwent.a U-turn when it metamorphosed into poly/multi-alignment under the new leadership.in New Delhi in 1998. The new foreign policy outlook.broadly had two components, namely, improving relations with the US and its Look East Policy-II. The turnaround in India-US relations from being estranged democracies during the Cold War to engaged democracies in the 2000s has played a central role in bringing out a shift in Chinas India posture over the last decade. India has been a democracy right since its birth as a modern nation-state in 1947. However, its sluggish economic growth and weak military profile that led to its defeat in 1962 seriously stained this aspect of Indias soft power. 8. With the rising India story, its democracy as an important component of its soft power has again come into the global limelight. India has more than 1 billion people. It is linguistically, culturally, racially, and religiously diverse, and it is growing economically at an enviable pace under democratic governmental institutions (except for the emergency period of 1975-77 when civil liberties were undermined). Its culture values peaceful coexistence, nonviolence, and religious tolerance. All of these factors, combined with the largest pool of English speakers outside the US, has increased Indias power of attraction without need for coercion or persuasion, a fact not lost on an envious, hard power-minded China. The country to which India has projected most of its soft power is the US, through the export of highly skilled manpower, consisting mainly of software developers, engineers, and doctors. 9. In military terms, post-1998 India has been enjoying strategic capital, in the sense that, unlike the rise of China, Indias military rise is not only not feared but it is felt to be desirable by the countries in the Asia-Pacific like Japan, Australia, South Korea, and ASEAN as a group. Most importantly even the US sees Indias military rise in its own interests.28 Interestingly, a rising India is making full use of this capital by emerging as a formidable military power over the last decade, apart from unveiling even more ambitious military plans for the future CHAPTER 3 MILITARY POWER Military Power 1. Military Power is military dimension of national power. National power embodies soft persuasive or attractive elements as well as its hard or military component. Military power can itself mean different things in different contexts; as military forces do different things ranging from defending national territory to invading other states; countering terrorists or insurgents, keeping the peace, enforcing economic sanctions, maintain domestic order. Proficiency in one task does not entail proficiency in all as good defenders of national territory can make poor peacekeepers and also may not be able to conquer neighbours. 2. Since beginning of civilization, military power has been the primary instruement nation states have used to control and dominate each other. With the growth of technology, the destructiveness of military power has reached apocalyptic proportions. 3. Throughout history, military power has been paramount and economic power a luxury. This has slowly changed to the point that the two roles have been reversed. Japan, China have relied on economic prosperity to finance formidable military forces. Conversely, erstwhile Soviet Union, Iraq and North Korea have relied on their military to build economic power with little or limited success. 4. Military power is the capacity to use force or threat of force to influence other states. Components of military power for a nation include number of military formations, armaments, organization, training, equipment, readiness, deployment and morale. Elements of Military Power 5. Elements of military power are worked out on the basis of military capability of nations. It includes numerical preponderance, technology and force employment. . Numerical preponderance has been exemplified in yesteryears; Napolean said , God is on the side of the big battalion 6. It is generally believed that states with larger population, more developed economies, larger military should prevail in battle. This is association of victory with material preponderance and beneath this lies the widespread perception that economic strength is precondition for military strength; that economic decline leads to military weakness and that economic policies merit co equal treatment with political and military considerations in national strategy making. Military preparedness requires a military (establishment) capable of supporting the foreign policy of a nation. Contributory factors are technology,leadership, quality and size of the armed forces. (a) Technology. The development and adoption of firearms, tanks, guns and aircraft have had a profound effect on the course of battles. To illustrate, if one reads the review of British operations during the initial stages of the Second World War, which Churchill gave in the secret session of parliament on 23 April 1942,one is struck by the fact that all defeats on land, on sea and in air have one common denominator-the disregard of technological capabilities being developed by Germans and the Japanese during the pre-war years. The U-boats played havoc with the British shipping and adversely affected their ability to move forces from one theatre of war to another, as also to sustain them. Conversely, the development of radar technology by the British during the war years gave them enormous advantage over their enemies. In the present-day context, capabilities in cyber warfare, space assets and smart strike weapons will give a great edge to the powers that are able to develop and operationalise such technologies. (b) Leadership. The quality of military leadership has always exerted a decisive influence upon national power. We have the examples of the military genius of Fredrick the Great, Napoleon, the futility of Maginot Line psychology of the French General Staff versus the blitzkrieg adopted by the German General Staff, and closer home the effect of superior military leadership led by Field Marshal SHFJ Manekshaw in Indias 1971 War with Pakistan. (c) Quality and Size of the Armed Forces. The importance of this factor is obvious. However, the question that has to be answered by the political leadership of the country is, how large a military establishment can a nation afford in view of its resources and commitments or national interests? CHAPTER 4 SHORTCOMINGS OF INDIAN MILITARY POWER Much has been written and said about the potential for Indian military power to play a greater role on the world stage, and perhaps check Chinas expanding capabilities in the future.National Security has attained multi-faceted dimensions with wider challenges in diverse fields.There has been growing understandings of these challenges and consequently measures are being taken to overcome the same. Indias remarkable economic growth and newfound access to arms from abroad have raised the prospect of a major rearmament of the country. But without several policy and organizational changes, Indias efforts to modernize its armed forces will not alter the countrys ability to deal with critical security threats. Indias military modernization needs a transparent, legitimate and efficient procurement process. Further, a chief of defense staff could reconcile the competing priorities across the three military services. Finally, Indias defense research agencies need to be subjected to greater ove rsight. Indias rapid economic growth and newfound access to military technology, especially by way of its rapprochement with the United States, have raised hopes of a military revival in the country. Against this optimism about the rise of Indian military power stands the reality that India has not been able to alter its military-strategic position despite being one of the worlds largest importers of advanced conventional weapons for three decades. Civil-military relations in India have focused too heavily on one side of the problem how to ensure civilian control over the armed forces, while neglecting the other how to build and field an effective military force. This imbalance in civil-military relations has caused military modernization and reforms to suffer from a lack of political guidance, disunity of purpose and effort and material and intellectual corruption. The Effects of Strategic Restraint Sixty years after embarking on a rivalry with Pakistan, India has not been able to alter its strategic relationship with a country less than one-fifth its size. Indias many counterinsurgencies have lasted twenty years on an average, double the worldwide average. Since the 1998 nuclear tests, reports of a growing missile gap with Pakistan have called into question the quality of Indias nuclear deterrent. The high point of Indian military history the liberation of Bangladesh in 1971- therefore, stands in sharp contrast to the persistent inability of the country to raise effective military forces. No factor more accounts for the haphazard nature of Indian military modernization than the lack of political leadership on defense, stemming from the doctrine of strategic restraint. Key political leaders rejected the use of force as an instrument of politics in favor of a policy of strategic restraint that minimized the importance of the military. The Government of India held to its strong anti-militarism despite the reality of conflict and war that followed independence. Much has been made of the downgrading of the service chiefs in the protocol rank, but of greater consequence was the elevation of military science and research as essential to the long-term defense of India over the armed forces themselves. Nehru invited British physicist P.M.S. Blackett to examine the relationship between science and defense. Blackett came back with a report that called for capping Indian defense spending at 2 percent of GDP and limited military modernization. He also recommended state funding and ownership of military research laboratories and established his protà ©gà ©, Daulat Singh Kothari, as the head of the labs. Indian defense spending decreased during the 1950s. Of the three services, the Indian Navy received greater attention with negotiations for the acquisition of Indias first aircraft carrier. The Indian Air Force acquired World War II surplus Canberra transport. The Indian Army, the biggest service by a wide margin, went to Congo on a UN peacekeeping mission, but was neglected overall. India had its first defense procurement scandal when buying old jeeps and experienced its first civil-military crisis when an army chief threatened to resign protesting political interference in military matters. The decade culminated in the governments forward policy against China, which Nehru foisted on an unprepared army, and led to the war of 1962 with China that ended in a humiliating Indian defeat. The foremost lesson of 1962 was that India could not afford further military retrenchment. The Indian government launched a significant military expansion program that doubled the size of the army and raised a fighting air force. With the focus shifting North, the Indian Navy received less attention. A less recognized lesson of the war was that political interference in military matters ought to be limited. The military and especially the army asked for and received operational and institutional autonomy, a fact most visible in the wars of 1965 and 1971. The problem, however, was that the political leadership did not suddenly become more comfortable with the military as an institution; they remained wary of the possibility of a coup detat and militarism more generally. The Indian civil-military relations landscape has changed marginally since. In the eighties, there was a degree of political-military confluence in the Rajiv Gandhi government: Rajiv appointed a military buff, Arun Singh, as the minister of state for defense. At the same time, Krishnaswami Sundarji, an exceptional officer, became the army chief. Together they launched an ambitious program of military modernization in response to Pakistani rearmament and nuclearization. Pakistans nuclearization allowed that country to escalate the subconventional conflict in Kashmir while stemming Indian ability to escalate to a general war, where it had superiority. India is yet to emerge from this stability-instability paradox. The puzzle of Brasstacks stands in a line of similar decisions. In 1971, India did not push the advantage of its victory in the eastern theatre to the West. Instead, New Delhi, underuberrealist Prime Minister Indira Gandhi, signed on to an equivocal agreement at Simla that committed both sides to peaceful resolution of future disputes without any enforcement measures. Indias decision to wait 24 years between its first nuclear test in 1974 and the second set of tests in 1998 is equally puzzling. Why did it not follow through after the 1974 test, and why did it test in 1998? Underlying these puzzles is a remarkable preference for strategic restraint. Indian leaders simply have not seen the use of force as a useful instrument of politics. This foundation of ambivalence informs Indian defense policy, and consequently its military modernization and reform efforts. To be sure, military restraint in a region as volatile as South Asia is wise and has helped persuade the great powers to accommodate Indias rise, but it does not help military planning. Together with the separation of the armed forces from the government, divisions among the services and between the services and other related agencies, and the inability of the military to seek formal support for policies it deems important, Indias strategic restraint has served to deny political guidance to the efforts of the armed forces to modernize. As wise as strategic restraint may be, Pakistan, Indias primary rival, hardly believes it to be true. Islamabad prepares as if India were an aggressive power and this has a real impact on Indias security. Domestic And Regional Constraints India faces several daunting domestic and border challenges within its own neighborhood that may prevent it from thinking more globally including the unresolved issue of Kashmir, an increasingly grave Maoist threat, Islamic terrorism from Pakistan, and unresolved border issues with China which broke out in war in 1962. Beijings effort to beef up its presence in South Asia is also seen as challenging Indian dominance there. The Lack of Strategy Indias military modernization remains, and likely will continue to be, an a-strategic pursuit of new technology with little vision. There is a whole host of problems that the nation faces, including: Little political guidance from the civilian leadership to the military. This is true even on the general issue of what Indias major goals should be. Even the Indian navy, which is often assumed to be the most forward thinking institution within Indias military, does not see itself as more than a naval blockade vis-à -vis Pakistan. Lack of organizational and institutional reforms. The need to reprioritize resources is never addressed, what is addressed is the procurement of new material, thus making modernization merely an exercise in linear expansion. No legitimate and transparent procurement system. As a result, purchases are often ridden with scandals, corrupt, delayed and highly politicized. Indias Defense Research and Development Organization (DRDO) is also a failed organization that is ideologically corrupt, but there has not been an honest attempt to put it under public scrutiny. Imbalance in Civil-Military Relations What suffices for a military modernization plan is a wish list of weapon systems amounting to as much as $100 billion from the three services and hollow announcements of coming breakthroughs from the Defense Research and Development Organization (DRDO), the premier agency for military research in India. The process is illustrative. The armed forces propose to acquire certain weapon systems. The political leadership and the civilian bureaucracy, especially the Ministry of Finance, react to these requests, agreeing on some and rejecting others. A number of dysfunctions ensue. First, the services see things differently and their plans are essentially uncoordinated. Coming off the experience of the Kargil war and Operation Parakram, the Indian Army seems to have arrived at a Cold Start doctrine, seeking to find some fighting space between subconventional conflict and nuclear exchange in the standoff with Pakistan. The doctrine may not be official policy, but it informs the armys wish list, where attack helicopters, tanks and long-range artillery stand out as marquee items. The Indian Air Force (IAF), meanwhile, is the primary instrument of the countrys nuclear deterrent. The IAFs close second role is air superiority and air defense. Close air support, to which the IAF has belatedly agreed and which is essential to the armys Cold Start doctrine, is a distant fourth. The Indian Navy wants to secure the countrys sea-lanes of communications, protect its energy supplies and guard its trade routes. It wants further to be the vehicle of Indian naval diplomacy and sees a role in the anti-piracy efforts in the Malacca Straits and the Horn of Africa. What is less clear is how the Indian Navy might contribute in the event of a war with Pakistan. The navy would like simply to brush past the problem of Pakistan and reach for the grander projects. Accordingly, the Indian Navys biggest procurement order is a retrofitted aircraft carrier from Russia. Indias three services have dramatically different views of what their role in Indias security should be, and there is no political effort to ensure this coordination. Cold Start remains an iffy proposition. Indias nuclear deterrent remains tethered to a single delivery system: fighter aircraft. Meanwhile, the Indian Armys energies are dissipated with counterinsurgency duties, which might increase manifold if the army is told to fight the rising leftist insurgency, the Naxalites. And all this at a time when the primary security threat to the country has been terrorism. After the Mumbai attacks, the Indian government and the people of India are said to have resolved to tackle the problem headlong, but today the governments minister in charge of internal security, Palaniappan Chidambaram, is more under siege himself than seizing the hidden enemy. Second, despite repeated calls for and commissions into reforms in the higher defense structure, planning, intelligence, defense production and procurement, the Indian national security establishment remains fragmented and uncoordinated. The government and armed forces have succeeded in reforms primed by additions to the defense budget but failed to institute reforms that require changes in organization and priorities. The Kargil Review Committee, and the Group of Ministers report that followed, for example, recommended a slew of reforms. The changes most readily implemented were those that created new commands, agencies and task forces, essentially linear expansion backed by new budgetary allocations. The changes least likely to occur were those required changes in the hierarchy. The most common example of tough reform is the long-standing recommendation for a chief of defense staff. A military chief, as opposed to the service chiefs, could be a solution to the problem that causes the three services not to reconcile their pr Gas Sensing Properties of Te Thin Films: Thickness and UV Gas Sensing Properties of Te Thin Films: Thickness and UV Thickness and UV irradiation effects on the gas sensing properties of Te thin films Abstract In this research, tellurium thin films were investigated for use as hydrogen sulfide gas sensors. To this end, a tellurium thin film has been deposited on Al2o3à substrates by thermal evaporation, and the influence of thickness on the sensitivity of the tellurium thin film for measuring H2S gas is studied. X-ray diffraction (XRD) analysis, scanning electron microscope(SEM) and Raman Spectrometer were utilized for characterizing the prepared samples. XRD patterns indicate that as the thickness increases, the crystallization improves. Observing the images obtained by SEM,à ità isà seenà that the grain size increases as the thickness increases, and consequently, fewer defects will be seen in the surface of the film. Studying the effect of thickness on H2S gas measurement, it became obvious that as the thickness increases, the sensitivity decreases and the response and recovery time increases. Studying the thermal influence of the thin film while measuring H2S gas,à it become s obviousà that as the detection temperature of the thin film increases, sensitivity and the response and recovery times reduce. To improve the response and recovery time of the tellurium thin film for measuring H2S gas, the influence of UV radiation while measuring H2S gas was also investigated. The results indicate that the response and recovery times strongly decreaseà using UV radiation. Introduction Tellurium is a P type semiconductor with narrow band gap and a gap energy of 0.35eV which makes it ideal for use in thin film transistors [1], gas sensors [2-4], optical information storage [5] and shields in passive radiative cooling [6]. Recently, it has been shown that the tellurium thin film is sensitive to some toxic gases like H2S [7]. Hydrogen sulfide is a toxic and corrosive gas which is formed in coal mines, oil and gas industries, chemical products plants, and the sewers. Exposure to small amounts of this gas (less 50 ppm) causes headache, poor memory, loss of appetite and irritability, while exposure to large amounts (most of 500 ppm) will cause death after 30-60 minutes [8]. So far, various semiconductor metal oxides have beenà producedà for detecting H2S gas such as SnO2, WO3, and CeO2à [9-11]. The main problem of these sensors is that theyà require high temperature for measuring H2S gas, and this high temperature will shorten the life of the sensor[12]. Measurin g gas through semiconductor metal oxide depends upon parameters like thickness of the thin film, deposition temperature, and the substrateà material. So far, few reports have been issued about the sensitivity of the tellurium thin film to some reducing and oxidizing gases such as NO2, CO, NH3, and H2S [4,7,13,14]. In this research, the influence of the thickness of the tellurium thin film on detecting H2S gas and also the influence of the film temperature and UV radiation while measuring H2S gas have been studied. Experiment details Tellurium thin films with thicknesses of 100, 200, and 300 nm measured by Quartz digital thickness gauge, were deposited on Al2O3à substrate by thermal evaporation of pure tellurium in a tungsten crucible. Substrates were cleaned for 30 minutes by alcohol and acetone in ultrasonic bath. The initial pressure of the vacuum chamber and the temperature of substrate while depositing were respectively 3Ãâ"10-5à mbar and 373K. The growth rate of the film and the deposition area were respectively 5nm/s and 100mm2. Gold electrodes were deposited on the surface of film through thermal evaporation and copper wires were attached to them by silver paste. The microstructure of the films was characterized through X-ray diffraction (XRD). The morphology of the films surface was determined by scanning electron microscope (SEM). Sensor response to various concentration of H2S gas was studied in a container made of stainless steel with a volume of 250cm3à .The electrical resistance of the senso rs was measured by a multimeter as a function of time. Gas limità detection was performed for the films with different thicknesses and at different environment temperatures. The sensors were also exposed to UV radiation while detecting H2S gas. The mechanism of gas detection was investigated by Raman spectroscopy technique. The spectra were recorded before and after exposure to the gas. Raman spectra of the films were recorded in back scattering geometry with a spectral resolution of 3 cm-1. The 785 nm line of Ar+à laser was usedà for excitation. Results and Discussion XRD patterns of tellurium films with different thicknesses are shown in fig. 1. In this figure, the peaksà denotedà with star are related to Al2O3à substrate. At 100 nm,à Te thickness peak of low intensity is observed at 27.77à °Ã which is related to Te (101) with hexagonal structure. At 200 nm, in addition to Te (101), another peak corresponding to Te (100) appears at 23.15à °. Finally, besides Te (100) and Te (101), a new peak is observed at 40.78à °which is related to Te (110) with hexagonal structure. From the XRD results, it can be inferred that, thickness increasesà theà results in an increase of film crystallinity due to the increase of the number of planes that generate diffraction. Fig. 2 shows the SEM images of prepared Te films at differentà thicknesses.à [S1]At 100 nm, the grains are separated from each otherà by aà large distance, thereby forming discontinuous and rough surface. Increasing film thickness leads to an increase of surface homogeneit y and continuity, grain size increaseà as well. Fig. 3 depicts the resistance variation of the tellurium thin films with different thicknesses at room temperature before exposure to H2S gas. It can be seen that the film resistance decrease with thickness increase due to reduction of irregularity in grain arrangement and inhomogeneity onà theà film surface,à which leads to a better charge carrier mobility. The sensitivity of the films to H2S is given by: S=à Where Raà and Rgà are the electrical resistance of the film in the air and the H2S respectively. Fig. 4 shows the effect of Te film thickness on sensitivity to 8ppm of H2S at room temperature.à Note that the film sensitivity decreasesà withà an increase inà thickness. To explain this behavior, it is worth mentioning that the proposed mechanism for H2S gas measurement is as follows: the oxygen in the air is adsorbed by the film surface, especially in the grain boundaries and film porosities. After adsorption, oxygen reacts with Te film surface and based on the film temperature, it can be ionized into O2, O2-, Oà (in the temperatures less than 150CÃâ¹Ã
¡ the ionization form is O2). These forms of oxygen ionization increase the film hole density which meansà a reduction of Raà in P type semiconductor such as Te. As H2S gas is added, it reacts with ionized oxygenà and the result will beà theà return of electrons inside the film and reduction of the hole numbers and increase of Rgà resistance. The reactions are shown below: O2(gas) O2(ads)(1) O2(ads)+ e O2(ads)(2) H2S(gas)+O2(ads) H2(gas)+SO2(gas)+ e(3) At 100 nm Te thickness, the presence of a high density of grain boundaries and defects results in a high H2S gas adsorption which causes noticeable variations in film electrical resistance,à indicating an increase of sensitivity. At higher thickness, where the grain boundary and defects densities decrease,à the changes in resistance are intangible involving a decrease in the sensitivity as shown in fig. 4. The other important characteristic of sensor is its selectivity. The sensitivity on exposure to 10 ppm of CO, NH3à and NO was found to be 3 %,40 % and -67 % (negative sign indicates reduction in resistance), respectively[]. Thus we see that the Te films have much larger sensitivity towards H2S gas in comparison to other gases. Fig. 5 shows the response kinetics of Te films at different thickness (100 nm and 200 nm) after exposure to 8ppm H2S. Considering the response and recovery times, the times for reaching 90% of steady-state values of Raà and Rgà respectivelyà can b e defined. It can be clearly seen in fig. 5 that thickness increase leads to an increase of response and recovery times. The former and the latter are due to high adsorption rate of H2S and O2à gases, respectively, at 100 nm by the great numbers of grain boundaries and defects [15]. Fig. 6 shows Raman spectra of 100 nm Te sample before and after exposure to 8 ppm H2S gas at room temperature. In both spectra, peaks at 123, 143 and 267 cm-1à are related to tellurium. Two other peaksà observed in sample before inducing H2S gasà at 680 and 811 cm-1à are assigned to TeO2à [16].à Notice that the intensity of oxide phase is much less than that of Te phase indicating that a low fraction of Te film is oxidized,à whichà isà due to Te atoms on the surface [17]. After exposure to H2S gas,à based onà the proposedà reaction mechanismà the TeO2à peaks have almost disappeared. In addition, no peak corresponding to H2S or compounds of sulfur or hydrogen is detected in f ilm after exposure to H2S gas. Fig. 7 shows the sensors sensitivity as a function of H2S gas concentration for 100, 200 and 300 nm samples at room temperature. The film to 100 nm Te thickness presents a linear response fromà theà 8 to 34 ppm range and the film sensitivity seems to saturate at higher concentration. As expected, from fig. 7à it can be seenà that the sensitivity decreases as the film thickness is increased. Figure 8 shows the results related to response and recovery time for all samplesà while being exposed to various concentrationsà of H2S gasà atà room temperature. Studying the resultsà it isà clearà that as the H2S gas concentration increases, the response time decreases and the recovery time increases.à Thisà is because as H2S gas concentration increases, the probability of a reaction between gas and ionized oxygen becomes more probable, and more reactionsà will be observedà in a shorter time which causes the resistance to change faste r and finally reach a constant level. As the concentration goes up, more H2S gas molecules are absorbed and their desorption requires a longer time. The resistance of different samples as a function of detection temperature before exposure to H2S gasà is shown in fig. 9. In all thickness, a decrease of resistivity is observed with temperature increase due to electrical properties of semiconductor, as well as increase of oxidation reaction rate. In the caseà ofà 300 nm Te films the variation of resistance is insignificant because ofà theà very low resistance of this sample. Fig.à 10 shows the results related to sensitivity as a function of temperature while being exposed to 8ppm of H2S gas. Investigating the results,à it is found that temperature rise leads to reductions inà sensitivity in all samples, because the number of charge carriers in samples increases asà theà temperature rises and as a result, when samples are exposed to H2S gas, no tangible resistance c hange is observed and sensitivity decreases [18]. In samples with 300nm thickness and with temperatures above 90Cà °Ã there is no sensitivity against H2S gas,à since the number of charge carriers is soà highà that their change is never tangible by reaction with H2S gas. Fig. 11 shows the recovery and response times as a function of temperature while being exposedà toà 8 ppm H2S gas. In all samples,à as the temperature rises the response and recovery time decreases. Overall, two factors are effective for a reaction: first, the molecules which are going to take part in the reaction must have a lot of energy, second, they must collide with one another in an appropriate direction. Temperature rise causes an increase in energy and more effective collisions will take place between reactants, and the response and recovery time decrease. To study the effect of UV irradiation on the sensor properties during the gas detection, samples are simultaneously exposed to 8 ppm H2S gas and UV radiationà atà room temperature. Fig. 12 shows a comparison between the sensor sensitivity of the UV exposedà and unexposed cases as a function of Te film thickness. It is obvious that application of UV radiation results in a dramatic reduction of sensors sensitivity. As it is well-know, UV radiation creates supplementary charge carriers by an excess of electron-hole pairs formation.à Increase of charge carriers numberà involves a decrease of resistance such that the changes of resistanceà areà not tangible while reacting with H2S gas. Fig. 13 presents the recovery and response times as a function of H2S gas concentration before and after exposure to UV radiation.à It is observedà that the recovery and response times strongly depend on UV radiation. These two parameters decrease with UV radiation due to creation of electron-hole pairs. The created electrons react with adsorbed oxygen, so the number of ionized oxygen reacting with H2S gas increase, which can result in an increase of reaction rate between oxygen and H2S gas. The above explanations can be summarized in the following reactions: O2(gas) O2(ads)(4) O2(ads) + e O2(ads)(5) hà ½ e + h O2à (ads)+ e 2O(ads)(6) H2S(gas) + Oà (ads) H2(gas) + SO(gas) +e(7) It is worthà noting that the increase of UV radiation intensity has no effect on sensitivity,à response and recovery times of Te sensors. Also, to evaluate sensor stability, the samples of 100 nm and 200 nm Te filmà wereà subjected to 8 ppm H2S at room temperatureà for 60 days, thenà their basic resistance and sensitivity were measured as shown in fig. 14. The results indicate that both resistance and sensitivity of sensors remainà nearlyà constant, confirming suitability of Te films for use as sensor. Conclusion In this work, thickness effect of Te films for H2S gas sensing are investigated. A strong dependenceà onà electrical resistance and sensitivity to Te film thickness is observed.à Thisà means that increasing the thickness leads to a decrease of sensor sensitivity and increase of response and recovery times.à Consideringà the sensing mechanism of Te thin films which is based on the interaction of ionized oxygen with H2S gas, the grain boundaries and the surface roughness could be considered as active sites for trapping the gas molecules. Thickness increase leads to a decrease of these active sites. The results show that although the Te sensor can operate at room temperature, a decrease of response-recovery times can be obtained at higher operating temperatures. Raman spectroscopy shows that adsorbed oxygen on the surface of Te films can be removed after exposure to H2S gas,à leading to changes in the film resistance,à UV radiation,à as well as response-recovery times. The prepared sensors present a stability in sensitivity and resistance for 60 days after exposure to H2S gas which confirmsà their ability toà beà usedà as H2S gas sensor.Ã
