Assess the Sociological Explanations of the Role of Culture

Assess the sociological explanations of the role of culture in contemporary society Culture is the behaviour, beliefs and characteristics of a particular group of people. Age groups, ethnic groups and social groups etc†¦ are all examples of groups of people that possess their own unique culture. The people within a culture are expected to follow the norms and values that are passed down through generation to generation. Over the past 30 years, different cultures have gradually intermingled due to an increasing number people immigrating to different countries, which each bring their own cultures, be it religious or pop culture etc†¦ This is particular visible in many western countries such as Britain, Canada and the United States, as there is a much higher level of ethnic diversity. The amalgamation of different cultures has also shaped people’s views on things like sexuality, gender roles and age roles etc†¦ Functionalists believe that culture benefits the whole of society. They believe that if everyone in society shares the same beliefs and ideas, i. e. a value consensus is reached, and then society as a whole can be kept in a civilised manner. They also believe that socialisation is a key factor, to shaping culture and society.Primary socialisation is taught by parents who teach children what they expect of them. It also develops their own personal characteristics, beliefs and values, which are largely influenced by their parents and family. Secondary socialisation is taught mainly by teachers in schools. Teenagers and young adults learn what is expected of them in larger society, outside of their home (e. g. what is acceptable and not acceptable based on age or gender etc†¦). Tertiary socialization occurs when individuals are integrated into the world and being to gain new ideas and values of socialization.Emile Durkheim, a French sociologist during the late 19th century and early 20th century, believed that culture is collectively formed and only exists collectively, meaning that culture can only be developed by a group of people and not by an individual. He believed that culture has many relationships with society, including a logical relationship (the idea that power over individuals belongs to certain cultural categories, and beliefs such as God), a functional relationship (the idea that culture creates common beliefs amongst individuals in society, strengthening social order). However, the unctionalist explanations are based on a more traditional society. They are outdated as some ideas do fit todays multi-cultural society. The classical Marxist theory culture as a way of expressing a ruling class ideology. This is where the bourgeoisie control the superstructure of society, the proletariats (working class) creating a false class consciousness, which further creates a false description of reality and the relationships between them and the proletariats. They also believe that culture reinforces the class structure. This means that culture is a way of maintaining the ideas of what each class can achieve.For example, the classical Marxist theory believes that in society, the rich population will always achieve higher than the poorer population, as they can afford to carry on their education to the highest level, whilst the poorer population are sifted out of the educational system at the earliest possible stage. The classical Marxist theory does not take into account the times when the working class rejects their control under the ruling class. This can be in the form of riots, strikes or even a group of people, who are in their own subculture who share the same beliefs about the relationship between the working class and the ruling class (e. . skin heads, punks). Neo-Marxist believes that the working class are being distracted from revolting against the ruling class. One of the most widely adopted forms of neo Marxism is the Frankfurt school. Two of its key members, Theodor Adorno an d Max Horkheimer, came up with the theory of â€Å"the culture industry†. This is the idea that popular culture is like a factory that produces standardized cultural goods (e. g. film, radio, magazines) that are used to manipulate mass society into being content, no matter how poor the quality of their lives are.They believe that mass culture encourages the working class to buy things that are false needs, which leads to a commodity fetishism. This is when capitalism affects the way people interact with each other based on the economic class the belong to. For example, under capitalism, everything that can be exchanged becomes a commodity. Things like labour can become a commodity, by selling your labour to an employer you are commoditizing yourself, and that defines the kind of relationship you and your employer will have.Overall, the neo Marxist theory sees that the population are passive victims of mass culture, who are distracted from the realisation of the quality of the ir lives. Neo-Marxists at the Birmingham University adopted Gramsci’s idea of cultural hegemony. This was an idea thought up by the Italian Marxist Antonia Gramsci, that capitalism would have to face and tolerate oppositional cultures. These are usually sub cultures, particularly within youth culture, that stand against capitalist values.Stuart hall gave the example of the skinhead as an oppositional culture, as he argued that they do not follow the norms and values set in place by capitalism, and resist capitalist views. This theory however is highly theoretical and lacks primary data. Feminists believe that culture is dominated by male ideas. They believe that men control women to serve their own interests, and that women are seen as â€Å"second class citizens†. The idea that females from an early age, are brought up being brainwashed by culture and society into thinking that women cannot strive to achieve high goals like men can.This is visible in the mass media. F or example, in many soap operas and sitcoms, women are portrayed as home makers, cleaners or secretaries, whilst men a portrayed as having high powered jobs. In the 1950’s, all advertisements for thing like kitchen appliances or cleaning products where women orientated, and many T. V commercials for these often saw the male as the breadwinner, returning home from work to his wife. However, this theory is becoming outdated as women in contemporary society are given the same opportunities as men.For example, women now have equal job opportunities as mean, as many of them are entering previously male dominated occupations. The interpretive, interactionist approach or the action theory as it’s more commonly known, is the idea that culture is made up of every bodies individual actions in society. It believes that people’s views and explanations of culture are moulded by the social groups in which they belong to. These interpretations of culture by individuals in soci ety come together to form what is known as the actionist theory. This theory however does not take into account shared beliefs or a value consensus.It also conflicts with the idea that culture cannot be formed by an individual, and can only be formed when there is a group of people. Semiotic culture attempts to define culture as types of symbolic human activity, creation of signs and a way of giving meaning to everything around. In this idea, culture is understood as a system of meaningful symbols, signs words and images. This approach can be adopted by any theorist (e. g. Marxist, feminist) no matter where they stand on the sociological spectrum. Post modernists theories of culture are based around the idea that society is adopting new cultures all the time.This is what is known as cultural diversity. Post-modernists believe that individuals are free to choose and design their own culture and identities. They also may pick up a hybrid culture, which is a mixture of different cultur es that is usually found in countries where there is a large culture diversity. Overall, I think that most of the theories have valid plausibility and evidence, especially Horkeimer’s and Adorno’s neo_marxist theory. However, Theory I find most plausible is the functionalist theory. I find that it has the most supportive evidence out of all the theories.

Analysis the Motorbike Market in Vietnam

Vietnam by motorbike take 61% of the total and by 4 times comparing with people who use car as main vehicle. Thus, motorbike market is an important part of Vietnam economy and considerable contribution to economic growth in recent years of Vietnam. Therefore, in this report are going to analyze the Motorbike market in Vietnam in both aspects: microeconomic and macroeconomic and bring out some conclusion about this market. Microeconomics: In this section, it will be analyzed into three elements such as demand, supply and price. Demand of consumer: In recent years, the demand of motorbike always grows up.According to the Vietnam Registry Department, until a half of 2011 Vietnam has about 17 million registration motorbikes and became one of countries has the ratio of people who use motorbike highest on the world. Table 2: Number of motorbike was registered Source: Vietnam Registry Department, 2010 Following above table, it can be seen that number of registered motorbike is increasing dr amatically year by year. In 2006, Vietnam had 1. 5 million of motorbikes but 5 year later this figure increased twice with 3 million motorbikes in 2010.These figures are shown that demand of Vietnamese people in buying motorbike very large ND this Is a complex market for Investors to Invest their capital as well as extend production. The main reason leaded to growing up of motorbike is reduced price of this product. For example, 10 years ago, a Honda dream motorbike was 30 million VEND (equivalent 2,000 USED at the same time), however after 5 year Honda was opened a industry in Vietnam and now price of a Honda motorbike is just from 10 million VEND (equivalent KUDUS at the present time). Price of produce changes, therefore demand of consumers change too.On the other hand, the second factor making demand of consumer raise Is national Income. According to General Statistics Offer, average per capita income in 2010 was approximately 1000 SAID, increasing 2. 5 times compare with income in 2004. Slogan (2010) is mentioned that to normal goods when income increases, the demand about it increases. Motorbike is a normal goods. This is sigh to show that when income of people increases, their demand increase too and they will spend more money for necessary goods, such as Vietnam is one of countries where is the most of using motorbike in the world.Thus, Vietnam is a large market and more potential for motorbike brands. Honda is brand which has most of market share in motorbike market because Honda is leader of this market when they were the first production at Vietnam over 10 years ago and they are always on the top of choice of consumers. According to General Statistics Offer, until 2009 there are two industries of Honda in Vietnam and the total of productivity of those is 1. 5 million produces per year.However, in 2010 Honda has invested 70 million USED to expend these industries, and improvement productivity to 2 million produces each year. Look back on the table 2, the number of registered motorbike in 010 was 3 million produces. Therefore, Honda was taken over a half of share market of motorbike market in Vietnam. Yamaha, Suzuki, SUM, Pigging†¦ Are the rest of brands in the motorbike market. In these brands, Yamaha is the most competitor of Honda with productivity each year is 1 million produces.In first years when motorbike has Just come to Vietnam, motorbike brands have set a high price because at that time demand of consumer was increasing highly and the main reason that time was taste. In recent years, with expanding on industries of old brands and setting up new brands of domestic production makes competition violently in motorbike market. As a result, reduce price is the optimal choice of producers. Domestic brands have exposed new produces with lower price, conformity with people who have low income.Therefore, other brands must to reduce price of their produce to competitive if they do not want to lose share market. Producers emul ate reducing price make demand of consumer increasing significantly. However, at this present, the supply of producers is over than demand of consumer, making surplus through the years, so in the future the price of produce will be continue reduce. On the other hand, producers must be kept productivity stability and in next some years reduce productivity to avoid surplus by yearly.

Draft for Statement of Purpose

I would like to begin by discussing the core values and ethical principles of Social Work. I came across the core values, according to the National Association of Social Work (NASW), associated with the social work profession, and I discovered the basic values which were listed were also ethical and moral values that I personally would consider as among the most important to consider as a social worker. The NASW listed six core values which included service, social justice, dignity and worth of the person, integrity, and competence. I would like to discuss each in further detail beginning with service.The type of service provided by the social worker is highly important and can make a huge impact as to whether there will be a successful outcome or not. The goal in the service provided by a social worker is to do all that is possible to help the individual(s) who are in need and to concentrate on the social problems that exist. It is important to go above and beyond, putting others in front of yourself, and provide the best service. In order to help those in need, a social worker must use their expertise, veneration, and experience as well as focus on the social problems at hand.In fact, social workers are encouraged to volunteer their knowledge and expertise at times provides services with absolutely no intention of receiving anything in return. I personally feel that although there may not be any financial compensation, just the fact that you could apply your skills and knowledge to help an individual, or individuals, is an even greater reward. Another core value is social justice, which refers to the idea of helping people realize that there are ways to improve certain types of living situations. The responsibility as a social worker is to always oppose and develop ways to change social injustice.Examples of different forms of social injustice include situations such as poverty, unemployment, discrimination, etc. As a social worker, attempts to assist individ uals, families, or groups who are particularly vulnerable such forms of social injustice, providing them with the resources and information available as to what options they may have to change their situation, while allowing them to see that, no matter what cultural or ethnic diversity, you are nonjudgmental, knowledgeable, understanding, and sensitive to their situation and will be there to help every step of the way.These are the actions of a truly sincere social worker as they all should be. The dignity and worth of the person is another core value which is also extremely important being a social worker. It is essential as a social worker to always have respect for the innate virtues, significance and self-worth of every person, treating each and every individual equally. However, it is a social workers job to take into account and be familiar with the cultural and ethnic diversity of a particular individual(s) in order to provide the best plan of care.As a social worker, it is i mportant to allow the clients’ to assess their social situation and their aptitude to promote change while assisting them by devising a plan which is significant to the clients’ individual needs. Another core value expressed by the NASW is the importance of human relationships. All people rely on other individuals for acceptance and as a support system when going through difficult times, or when having to make important decisions.As humans, we look for that support from other, therefore, social workers welcome the idea of other people being important factors to the healing, or helping, process of an individual(s). Social workers have realized the importance of developing stronger relationships between people to create a positive outcome and strengthen the well-being of individuals, families, social groups, organizations, as well as communities. The next core value, which I personally have always lived by in my own life, is integrity.A social worker should always act in a trustworthy manner in all situations and to always be aware of and remember the mission of the profession, the values expected to uphold, and those ethical principles and standards associated with the social work profession as a whole. They should continue to practice honesty and be responsible of upholding those ethical practices within the organizations they are affiliated with. Competence is the final core value discussed.A social worker should have the knowledge, resourcefulness, and dexterity to perform the job correctly while always continuing to improve their area of competence as well as strengthen and improve their abilities as a social worker. There is always new knowledge available which can help improve your skills as a social worker. I believe it is the responsibility of a good social worker to always be aware of any new information, theories, and research studies because there is always room for improvement and the more skillful and knowledgeable you are, the better work you can do to really help clients and society as a whole.I would now like to take this opportunity to discuss social work on a much more personal level, as it means to me. When I first began high school, I knew without a doubt that this type of work was what I wanted to do and what I wanted to major in when I went to college. I began with psychology because I was intrigued by questions such as why we think the way we do, or what makes one person turn out this way or think a certain way while the next person can behave completely different. The human brain and how it functioned, in general, was something I was completely fascinated by.And I still love psychology and everything about it, however, throughtout the years, I discovered my passion for wanting to help people in whatever way I could. Although my work experience included many very different types of work, I noticed one commonality between them all which was interacting with people, and helping people in some form or ano ther, and it was something I really loved doing and was remarkably good at it as well. Helping someone who was upset or angry and seeing them walk away with a smile and a whole new attitude made my day.In fact, I will find myself shopping in Wal-Mart and end up helping a complete stranger locate something they were looking for or even assist them in choosing which gift to purchase for a loved one. I realized that helping people just comes naturally to me. Even in my personal life, I was always the honest, trustworthy, and caring friend that my friends would come to when they needed help. My point is that my own morals, values, and beliefs which I live by and grew up with go hand in hand with those six core values every social worker should possess.This is why I decided that returning to school to obtain my master’s in social work was a much better fit for me that simply receiving a master’s in psychology. A career in social work is exactly what I would love doing for a living. When it came time to choose a concentration, I had to make a choice between mental health and family and children services. I once again looked at my own life. I have always had an interest in all areas of mental health. I have seen family members fighting addiction.I personally fought with anxiety, panic attacks, and depression after my son passed away from SIDS the day he made three months old as well as my battle with ADD when I was a child. When I was a teenager, I became very close to this wonderful family whose youngest daughter had been diagnosed with Down syndrome. Her name was Amy and although we were the same age, her mentality was that of about a ten year old. Amy and I became very close and spent a lot of time together for many years.We would go to all sorts of things together but quite often we would attend events where there would be many other children and adults with a variety of mental disabilities. I was fortunate enough to meet many of these individuals a nd their families as well and learned a lot about the many different mental handicaps. These opportunities increased my knowledge and curiosity as well. Therefore, due to my own life experiences, I have decided to concentrate in mental health. As an undergraduate at Southeastern Louisiana University, I learned a lot as far as my academic capabilities.Throughout high school, I never had to actually study or even really try very hard at all to maintain honor roll and stay in Beta Club so it took me awhile to adjust once I started college. I had to learn the best way for me to study and manage my time. Another hard lesson which I wish I would have picked up on much sooner was just how important those â€Å"A’s† were to my GPA. Although I figured it all out, my regret was that if I would have learned just a bit sooner my final GPA of 2. 895 would have been much, much higher!My strength academically is my love of knowledge and learning new things. I just can never get enoug h of that. I am so excited about the opportunity to attend USC to obtain my master’s in social work. After speaking with a few people who told just how great of a school I would be attending made me even more confident that I made the right decision when choosing which online university to attend. I know I made the right choice for my future and am looking forward to not only beginning my classes but also knowing that this is the beginning of the career I have been wanting for some time now.

Domestic Terrorism Research Paper Example | Topics and Well Written Essays - 1750 words

Domestic Terrorism - Research Paper Example Since they are illegal, terrorist organizations often resort to illegal ways of financing their activities such as extortion, violent robbery, drug trafficking, kidnapping, and arms smuggling. In recent years, drug trafficking has emerged as the biggest income source for these organizations (Crews and Tarzi, 2008). A number of studies have shown that the link between terrorism and drug trafficking is strong particularly in countries that are either the hubs of terrorism planning and organization or the main target of terrorism. It is for this reason that drug lords create domestic terrorism against the United States troops and the indigenous Afghanistan population (Shanty, 2011). This paper will discuss how drug lords in Afghanistan create domestic terrorism against United States troops and indigenous population in Afghanistan. According to the American government and Afghanistan government officials, the profits from drug trafficking in Afghanistan was estimated to be about $3.2 bil lion in 2012. The bulk of this profit went to Taliban warlords, as well as other militants. It is estimated that Afghanistan is currently producing nearly 90 percent of the global supply of illegal opium and about 85 percent of the world’s heroin supplies and morphine come from the country (Piazzo, 2012). Opium is the largest cash crop in Afghanistan; in 2006local export revenues from the crop constituted about 35 percent of the nation’s gross national product. At the same time, opium production employed nearly 14 percent of the country’s population. While it is clear that opium production in Afghanistan is critical for the country’s economy, illicit opiate production and trade is considered by many policy analysts, media commentators, academics, and politicians as a crucial contributor to terrorism acts in the country targeting indigenous population and United States troops. The Afghan Taliban extremist group uses opiate drug revenues to finance itself, mainly by taxing refined products, stocks of harvested poppy, and drug crop cultivation (Peters, 2009). Typically, media sources report the Taliban resistance within the borders of Afghanistan, training camps within Pakistan borders, and daily opinions of United States troop conflicts with Taliban forces. However, there is little reporting in regard to drug lord territory and border control in Afghanistan, as well as the drug lord contribution to terrorist acts against the indigenous population and the United States troops within the borders of Afghanistan (Crews and Tarzi, 2008). Various investigations have revealed that drug trafficking significantly supports terrorism in today’s world, particularly after the United States invasion in Iraq and Afghanistan. It is no doubt that drug trafficking is a very lucrative business and it generates big profits that are used for illegal activities including supporting terrorism (Leu, 2008). Drug trafficking has extensively benefited fr om political, economic, social and technological. Al Qaeda, Sunni extremists, and Taliban are some of the terrorist organizations that significantly benefit from selling and shipping of illegal drugs. Investigations have found that the proceeds and profits realized from drug trafficking are usually laundered through certain legal business and pumped back to terrorist organizations and their associates who then use to fund terrorism (Dolan, 2005). The Afghanistan

Consumer Buying Behaviour Literature review Example | Topics and Well Written Essays - 3000 words

Consumer Buying Behaviour - Literature review Example Therefore, this assumption challenges the thought of an international consumer culture with homogenised consumer sectors as well as customs, by declaring that those expenditure practices are shaped by the local outlines within which they take place (Bond et al, 2004, p. 33). Youth forms one of the biggest markets around the globe for cell phones, with more than 201 million subscribers between 18 to 25 years of age. Cell phones have appeared as signs of customer revolution, turning into a necessary product and having ‘ubiquitous’ part in the expanding retail landscape. The term customer revolution has as well been extensively used to represent the increase in consumption of cell phones among youth (Munusamy et al, 2010, p. 22). Two distinct attitudes to brands that describe the selection of a mobile phone are by â€Å"attitudes towards the cell phone brand name on one hand and attitudes towards the network on the other† (Usunier & Lee, 2009, p. 372). Whereas cost a nd constancy of service were found to control selections between network suppliers, selections between cell phone brands were influenced by new technology aspects, for instance, ‘memory’ and ‘SMS options’, more than its size.... The diffusion pace is said to rely mainly on manufacturing costs (Perrey & Spillecke, 2011, p. 211). Cost and properties were considered as the most essential causes influencing the choice to buy modern cell phone model among the respondents as exhibited. In accordance with the survey close to 90 percent and more than 95 percent, for cost and properties respectively, believed that cost and properties had influenced their selection procedure at least relatively much. â€Å"Cost might have controlled the decision making in the sample more than it does for the whole population, as the average net income in the target groups was relatively low† (Hackley, 2010, p. 192). Company’s order or sales representative’s suggestions were considered as the least significant reasons. The selection of the operator was influenced mainly by cost and audibility: more or less 93 percent thought that price the operator asks had influenced their selection at least relatively much. Addit ionally, audibility was the next most significant cause: 92 percent thought that audibility had influenced their choice at least relatively much (Soder & Wiedmaier, 2006, p. 99). Other causes of considerable significance were properties, companions' selection of the operator, contract form and free calls. Sales representative and employer were the least significant influencing the selection of one's operator. Majority of the popular services used these days are ‘logos’ and ‘ringing tones’. â€Å"More than 80 percent of the respondents had ordered logos and tones for their mobile devices. These two were chased by cell phone bill inquiry - 71 percent had ordered - and call

Teacher-Centered or Student-Centered Pedagogy Research Paper

Teacher-Centered or Student-Centered Pedagogy - Research Paper Example Educational institutions, therefore, are tasked with putting the priorities of the student first especially in the provision of learning materials and classrooms as opposed to according teachers the necessary teaching materials (Weimer 78). Similarly, while student-centered pedagogy is critical in infusing collaborating skills during learning, under a teacher-pedagogy this is absent. This implies that teacher-pedagogy stifles the student’s innate talents and socialization skills because it isolates the learner into doing things on his own. The teacher approach is equally deemed retrogressive because it suppresses the independence that is integral in harnessing creative and critical thinking processes for the student. By learning on their own, students find an opportunity to develop the curiosity of excavating other forms of relevant knowledge in their respective areas of study. The method as opposed to teacher-approach is fundamental because it encourages group work. It, thus, allows communication across learners of divergent capacities and how their immediate collaboration with the teacher can post a positive result for long-term purposes. However, while teacher-centered pedagogy ensures that the learner is constantly under supervision to answer the fundamental questions troubling the learner, it still lacks student-friendly approach. Contrastingly, student-pedagogy approach while it recognizes the need for monitoring, it is sensitive on feedback to identify the areas that require urgent correction.

Short answers - Coursework Example Any archeologist will say that an artifact’s context is as important as its characteristics for revealing information about the past. The importance of context may extend to a research setting whereby archeologists work. Awareness of the context enables public archeologists to recognize the impacts their research have on the communities within which they work, to include community members in the research as equal participants where they can and if opportunity arise and to actively engage in social change through the research (Stottman 141). At this stage of evolution, man was walking on all fours and had chimpanzee like body features. It is funny because there is a man in the photo who can walk with the legs only without using his hands. The other men are shocked and he is laughing at them but they are not amused. The gracile specimens from Olduvai George are Homo habillis but there are some provisos (Robinson, David & Ash). Their spinal cords’ opening is near the middle of the skull. The skull base is small but its width is bigger. Their faces are small in width and their nasal openings are sharply defined. Moreover, their post canine teeth are small. They had flat noses and projecting lower jaws that made them to look like apes. They had small brains, strong arms, curved fingers, small canine teeth, stood on two legs and walked upright (Robinson, David & Ash). Jane Goodall is a British anthropologist and primatologist presently celebrated for his immense contribution in research regarding chimps. This is especially in terms of their interactions and relations in terms on family structure carried out in

What do we mean by navigating another culture Essay - 1

What do we mean by navigating another culture - Essay Example When people from another culture interact with that particular society, they have to understand the cultural behavior of the host society and refrain from offending them by any indication that they do not respect the other culture. For this, they have to examine various characteristics and ramifications of another culture. As per the experts, all cultures share four major characteristics which are common in different cultures (Sarkar, 2010). It includes symbols which reflect on the art, religion, language and finance of that particular culture. When dealing with people from other culture, it is necessary to keep the open mind and learn the nuances of the other culture for a successful social outcome. When navigation of other culture is concerned, it is also necessary for a person to learn the core philosophy of that culture’s values (Hofstede et al, 2010). He or she should also understand various geo-political, socio-economic and cross-cultural factors such as traditions, customs, religious and social values such as taboos and ethos at the time of navigation in another culture. The person while navigating another culture, should always remember that something such as lack of respect, appreciation or ignorance about another cultural milieu can lead to breakdown in communication and goodwill from the people of another culture. In fact, if one tries to understand or imitate their ways while with them, it will lead to wholehearted support as well as enhancement of goodwill. Sarkar, A,N.

The notion of a basic right Essay Example | Topics and Well Written Essays - 1250 words

The notion of a basic right - Essay Example There is no law or declaration needed for him to enjoy that right. Nor can there be law or declaration that can stop him from enjoying that right as well. Another example is the basic right of a laborer to receive wages. As long as one is considered as an employee, the right to receive wage is already implied. Maybe a contract is needed to stipulate how much he will receive and how often he'll receive it, but no clause in a contract is needed to establish that right, nor can there be a clause depriving him of the right to receive wages. With or without a contract, one shall be paid for his labor. So we have established two aspects of basic right. First, it is automatic. And second, it is inalienable. It is automatic because as mentioned earlier, for as long as one has the status, one has the right - no need for a grant or declaration. It is inalienable because it cannot be taken away from him. He cannot be deprived of it, nor can he surrender it. As the clich goes, no man is an island. Therefore we have evolved not just into human beings but into social beings as well. We humans cannot live solely by ourselves. It doesn't matter how big or small our community is. It may only consist of our immediate families like in primitive tribes, or it may consist of millions of people like in a highly urbanized city. The point is; we have to co-exist with another. And because of this, civilization as we know it evolved. An important part in all forms of societies is the government, as it holds the society together. It may not be the complex form of government like the one we have now. It can be as simple as a group of elders in a tribe. The important thing is they provide order and security in the community. Since the government charts the course of the community, what now is the role of the individual members If a person is not a leader nor is part of the government, will he have any say on the way the community is being led Will he have any participation at all For example, in a democracy, though there is a central body governing the people, major decisions are made by all the members, like the act of voting during senatorial or presidential elections. Individuals may also give their views in forums or survey that will be considered by the people in their government. They may have rallies to convey their approval or disapproval in the way they are being led. Participation may come in different forms. The important thing is, the opinion of a member is considered. And such opinion may influence the direction of the nation. Government Participation as a Basic Right The community is composed of individuals; a country is composed of its citizens. Hence, whatever it is the government does, ultimately, it will affect the individuals composing it - its citizens. For example, a state chooses to impose a certain tax to be used to build infrastructures. Obviously, all the citizens will pay it. Everyone within its territory is affects. And because of this, it is but fair that individual members consulted or at least have a say in government activities. However can we consider government participation as a basic right First test: Is it Automatic We have said earlier, basic rights are automatic. As such, can we say that all humans have the right to participate in their corresponding governments If one is an American citizen, is he granted the basic right to particip

What are the 3 key factors to consider when buying merchandise for a Essay

What are the 3 key factors to consider when buying merchandise for a high street fashion brand such as Topshop - Essay Example As buying occurs in set periods it’s further necessary to have significant foresight. Another prominent factor that buyers must consider is quality control (Goworek 2005, p. 9). While there is generally a quality control department it’s recognized that they contribute to finalizing the aesthetic aspects of the fit, shape, length and proportion of the garment; additionally, it may be necessary to test the fabric to ensure that it matches the end retailer’s standards. The final factor that buyers must consider when purchasing merchandise for a high street fashion brand is progressive sales of past brands (Goworek 2005, p. 17). This is a slightly complex notion as it necessitates that buyers consider the specific sales of garments in the range and recognize then effectively manage these purchases in the context of future buying patterns. While it may not always be possible to purchase the same garments the buyer can match specific trends within these ranges accordin g to retail tendencies to achieve maximum

Informative Synthesis - Essay Example However, the anticipated environmental concerns and possible health and life threatening effects are consistently increasing the international organizations’ condemnation on the eminent nuclear energy in Iran. Indeed, the nuclear reactors tragedy in Fukushima Japan brought severe and lifetime effects that proved to be dangerous and inevitable (Greenpeace 1). However, the significance of this critical subject hails from the fact that the host nation is a minority nation with more economical interests than human or global security concerns. Iran is indeed not in any way ready to compromise its quest in this project. Actually, the urge to make their dream for a nuclear source of energy has only grown more real. Additionally, Iran has been concealing a ploy to develop uranium enrichment in its territories. Indeed, Iran produced 215 billion kWh gross in 2008 generating a per capita consumption of about 2000 kWh/yr. Out of these production, 80% of its electricity was from gas and 16 .5% from oil. In fact, the nuclear energy reactor started up in Iran on 8 May 2011 through September 2011 after many years of construction and many consistent efforts against ever increasing international opposition. With 75 % production capacity realized in March, the prospects of the project oversee the project entering commercial operation about April 2012 (World Nuclear Association 1). Subject to these developments, the international organizations like the UN Security council and international governments like the US institute sanctions, trade barriers, and diplomatic withdrawals against Iran with a hope of convincing or even coercing Iran to compromise on its pursuit for Nuclear energy (UN Security council 1-12). However, despite the stringent terms, Iran has not shown any signs of giving in to international pressure where they prioritize their economic interests on nuclear energy before international interests. This puts to question the mode of decision-making that Iranian lea dership adopts on matters of global concern like the nuclear energy. The significance of international pressure on nuclear energy in Iran is a relevant issue on the University of Alabama student. I addressing this topic, I will focus on opinion articles, "Only Crippling Sanctions Will Stop Iran" of March 2, 2012 by Emanuele Ottolenghi and "Starving Iran Won't Free It† March 2, 2012  by Hooman Majd. The article, "Only Crippling Sanctions Will Stop Iran" of March 2, 2012 by Emanuele Ottolenghi is however more effective in that it draws the history of important Iranian decisions, how Iranians value sanctions, what drives the Iranians to change and the respect accorded to the Iranian government by the Iranians. This will help in analyzing the effect of the international sanctions against nuclear energy in Iran. Emanuele holds the opinion that the western allies assume that Iran’s leaders are rational actors, and rely on cost-benefit analyses to reach important decision (O ttolenghi 1). Hence, they assume that their continued gradual increase in the costs of Iran’s nuclear pursuit will lead to Tehran concession in the current nuclear standoff between the western decision makers and the Iranian decision makers. They expect the Iranian decision makers to behave rationally agree to a compromise and ignore Iran’s perspective on costs already incurred, the price of completing the journey and the advantages of turning back subject to the continued international pressure (Ottolenghi 1). The Iranian decision makers do not necessarily behave as assumed by the Western decision makers. History shows that the Iran’s decision makers are impervious to cost-benefit analysis and have never been isolationists. Hooman recognizes the fact that coercion, sanctions or exiles and their enablers

Discuss the importance of dreams in the play Essay Example for Free

Discuss the importance of dreams in the play Essay Arthur Asher Miller (October 17, 1915 February 10, 2005) was an American playwright, essayist and author. He was a prominent figure in American literature and cinema for over 61 years, writing a wide variety of plays. Miller was born into a moderately-wealthy Jewish family in New York City. His father, Isidore Miller, was a ladies-wear manufacturer and shopkeeper who was ruined in the Great Depression. His mother, Augusta, was a housewife who valued literature and education. His sister, Joan became an actress. Death of a Salesman is a 1949 play by Arthur Miller and is one of his most famous and commonly revived works. Viewed by many as the American Dream of achieving wealth and success, Death of a Salesman made both Arthur Miller and the character Willy Loman household names. Some of the other titles Miller considered for the play were The Inside of His Head and A Period of Grace. The American Dream is the faith held by many in the United States of America that through hard work, courage, and determination one can achieve a better life for oneself, usually through financial prosperity. These were values held by many early European settlers, and have been passed on to subsequent generations. What the American Dream has become is a question under constant discussion, and some believe that it has led to an emphasis on material wealth as a measure of success and/or happiness. The American dream is a dream of having 2 children and living in a perfect house with financial security. This ideal is closely related to Horatio Algerism. http://en. wikipedia. org/wiki/American_dream In the play Death of a Salesman, dreams are discussed and shown in many different ways throughout the play. There are dreams that happen during ones sleep, hopes and ambition type dreams, day dreams, fantasies and national/cultural dreams. In this play all are explored, and the national dream focused on is The American Dream. Dreams in this play stimulate the characters reactions and actions; they also affect the way the play is structured and explain behaviour of both the past and present. The play is unusually structured; there are no scenes just three main sections, Act 1, Act 2 and the Requiem. Within Act 1 and Act 2, there are several dreams and possibly flashbacks but the audience is unaware of what is real or not. The American Dream features in the play but not informing the audience that The American Dream is what it is partly focusing on. On page 82, Biff says Weve been talking in a dream for fifteen years. First of all the reader thinks hes saying hes been taking in the dream for 15 years but reading the sentence over we see talking. The reader thinks that it means the American dream, and at this point in the play Biff realises himself and his family has been trying to live this dream but are unsuccessful. The American Dreams is partly to do with status and having the best of everything. It also focuses on popularity, success, ownership, wealth and your house and objects within it. The American Dream is linked to capitalism and consumer culture, which is when we are sold items we dont really need. This is a symbol of success and if you can afford these luxury items they are a fall back for your family. When someone dies their family receives insurance, not only life insurance but also insurance for the object used in the death, for instance a car. This is all part of Willys plan to make his family more wealthy. Willy is scared of becoming an ordinary man, which in those days was a man that can no longer afford the luxury items that Willy possesses, when Linda is talking to Biff on page 44 she says Willy Loman never made a lot of money. His name was never in the paper. Hes not the finest character that has ever lived. But hes a human being, and a terrible thing is happening to him. So attention must be paid. This shows the reader that Linda knows about Willys depression and that she knows he is becoming and has a fear of becoming a typical, ordinary man. This is not what Willy wants or wanted at all, Willy wanted to be well known around the country and great, successful. The depression that Willy held may have been caused by the lack of positive attention, his lack of progress in his job or his fear of becoming this ordinary man that he never wanted to be. Linda also knows that in his last months or weeks, herself and her sons need to make up to Willy and give him the most positive attention that they can. On page 44 Linda says Attention, attention must be finally paid to such a person. This is also evidence to suggest Willys want for death. Willy is not progressing at all in his job, his ex boss son is now at the top of his career ladder but Willy, still near the bottom should have retired. But his dreams and passion to become rich and successful meant that he forced himself to carry on working and hope that one day these dreams will be fulfilled.

Electric Filed Strength And Electric Flux Density

Electric Filed Strength And Electric Flux Density All bodies are made up of atoms, which consist of a nucleus containing protons (+ve) and neutrons (neutral) and surrounding the nucleus are orbiting electrons (-ve). When a body is uncharged it is electrically neutral, it has the same negative charge as positive charge. If a conductor had a deficit of electrons it would exhibit a net positive charge and if it was to have a surplus of electrons it would exhibit a net negative charge (remember the previous study of the atom reference +ve/-ve ions). An imbalance in charge can be produced by friction (removing or depositing electrons using materials such as silk and fur, respectively) or induction (by attracting or repelling electrons using a second body which is, respectively, positively or negatively charged). Coulombs Law states that if charged bodies exist at two points, the force of attraction (if the charges are of opposite polarity) or repulsion (if the charges have the same polarity) will be proportional to the product of the magnitude of the charges divided by the square of their distance apart. Thus: + + + Direct Inverse Proportionality Maths Q1 and Q2 are the charges present at the two points (in Coulombs), d is the distance separating the two points (in metres), F is the force (in Newtons), and k is a mathematical constant depending upon the medium in which the charges exist. In a vacuum or free space, ÃŽÂ µ0 is the permittivity of free space (8.854 x 10-12 F/m Farad per meter). The force exerted on a charged particle is a manifestation of the existence of an electric field. The electric field defines the direction and magnitude of a force on a charged object. The field itself is invisible to the human eye but can be drawn by constructing lines which indicate the motion of a free positive charge within the field; the number of field lines in a particular region being used to indicate the relative strength of the field at the point in question. The figure above shows the electric fields between charges of the same and opposite polarity. The figure below shows the field which exists between two charged parallel plates. B A As illustrated above, plates A and B are doped and charged to different potentials. If an electron that has a negative charge is placed between the plates, a force will act on the electron tending to push it away from the negative plate B and towards the positive plate A. Similarly, a positive charge would be acted on by a force tending to move it toward the negative plate. The region between the plates in which an electric charge experiences a force, is called an electrostatic field. The direction of the field is defined by the force acting on a positive charge placed in the field, i.e. the direction of the force is from the positive plate to the negative plate. Such a field may be represented in magnitude and direction by lines of electric force drawn between the charged surfaces. The closeness of the lines is an indication of the field strength. Whenever a p.d. is established between two points, an electric field will always exist. The figure above shows two parallel conducting plates separated from each other by air, and are connected to opposite terminals of a battery of voltage V volts. There is therefore an electric field in the space between the plates. If the plates are close together, the electric lines of force will be straight and parallel and equally spaced, except near the edge where fringing will occur (see previous figure). Over the area in which there is negligible fringing, E is the electric field strength (V/m), V is the applied potential difference across the parallel plates (V) and d is the distance (m). **Note: Electric Field Strength is also called Potential/Voltage Gradient. A unit electric flux is defined as emanating from a positive charge of 1 coulomb. Thus electric flux à Ã‹â€  is measured in coulombs, and for a charge of Q coulombs, the electric flux à Ã‹â€  is equal to Q coulombs. Electric flux density D is the amount of flux passing through a defined area A that is perpendicular to the direction of the flux: à Ã‹â€  is the electric flux measured in coulombs, Q is the electric charge also measured in coulombs, and A is the area in m2 over which the flux is distributed. Problem 1: Two parallel rectangular plates measuring 20cm by 40cm carry an electric charge of 0.2  µC. (a) Calculate the electric  ¬Ã¢â‚¬Å¡ux density. (b) If the plates are spaced 5mm apart and the voltage between them is 0.25 kV determine the electric field strength. Solution 1: PERMITTIVITY At any point in an electric field, the electric field strength E maintains the electric flux and produces a particular value of electric flux density D at that point. For a field established in vacuum (or for practical purposes in air), the ratio D/E is a constant ÃŽÂ µ0, i.e. ÃŽÂ µ0 is called the permittivity of free space or the free space constant. The value of ÃŽÂ µ0 is 8.854 x 10-12 F/m Farad per meter. When a dielectric (i.e. insulating medium separating charged surfaces), such as mica, paper, plastic or ceramic is introduced into the region of an electric field, the ratio of D/E is modified. ÃŽÂ µr is called the relative permittivity of the insulating material and indicates its insulating power compared with that of vacuum. ÃŽÂ µr has no units and typical properties of some common insulating dielectric materials are shown below. The product of ÃŽÂ µ0 ÃŽÂ µr is called the absolute permittivity, ÃŽÂ µ, i.e. As discussed earlier, the dielectric is an insulating medium separating charged surfaces and has the property of very high resistivity. They are therefore used to separate conductors at different potentials, such as capacitor plates or electric power lines. The dielectric strength of an insulating dielectric is the maximum electric field strength that can safely be applied to it before breakdown (conduction) occurs. The amount of charge produced for a given applied voltage on the two parallel plates shown earlier will depend not only on the physical dimensions but also on the insulating dielectric material that appears between the plates. Such materials need to have a very high value of resistivity (i.e. they must not conduct charge) coupled with an ability to withstand high voltages without breaking down. A more practical arrangement of parallel plates with an insulating dielectric material is shown. In this arrangement the ratio of charge, Q, to the potential difference, V, is given by the following relationship. A = area of one on the plates, in m2 D = thickness of the dielectric in m ÃŽÂ µ = absolute permittivity of the dielectric material *Later learning, i.e. the parallel plate capacitor/capacitance and physical dimensions. à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ single pair of plates à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦ arrangement of n plates Problem 1: The  ¬Ã¢â‚¬Å¡ux density between two plates separated by mica of relative permittivity 5 is 2 µC/m2.

In effect, it is a reservoir into which charge can be deposited and then later extracted. In its simplest form a capacitor consists of two parallel metal plates which are separated by an insulating material known as a dielectric. C:Documents and SettingsHarveyMy DocumentsMy PicturesPicturePicture 028.jpg Because of the dielectric, current cannot flow from one plate to the other. When the capacitor is connected to a dc source, electrons accumulate on the plate connected to the negative supply terminal. The negative charge repels electrons from the atoms of the other plate. These electrons flow away to the positive terminal of the dc source; this leaves the plate positively charged. C:Documents and SettingsHarveyMy DocumentsMy PicturesPicturePicture 032.jpg If the capacitor is disconnected from the supply, the charges remain. The capacitor stores the electric charge indefinitely. The symbols for a fixed capacitor and a variable capacitor used in electrical circuit diagrams are shown below. Typical applications include reservoir and smoothing capacitors for use in power supplies, coupling a.c. signals between the stages of amplifiers, and decoupling supply rails (i.e. effectively grounding the supply rails as far as a.c. signals are concerned). The following figures illustrate what happens to a capacitor when it is charging and discharging. If the switch is left open (position A), no charge will appear on the plates and in this condition there will be no electric field in the space between the plates nor will there be any charge stored in the capacitor. When the switch is moved to position B, electrons will be attracted from the positive plate to the positive terminal of the battery. At the same time, a similar number of electrons will move from the negative terminal of the battery to the negative plate. This sudden movement of electrons will manifest itself in a momentary surge of current (conventional current will flow from the positive terminal of the battery towards the positive terminal of the capacitor). Eventually, enough electrons will have moved to make the e.m.f. between the plates the same as that of the battery. In this state, the capacitor is said to be fully charged and an electric field will be present in the space between the two plates. If, at some later time the switch is moved back to position A, the positive plate will be left with a deficiency of electrons whilst the negative plate will be left with a surplus of electrons. Furthermore, since there is no path for current to flow between the two plates the capacitor will remain charged and a potential difference will be maintained between the plates. Now assume that the switch is moved to position C. The excess electrons on the negative plate will flow through the resistor to the positive plate until a neutral state once again exists (i.e. until there is no excess charge on either plate). In this state the capacitor is said to be fully discharged and the electric field between the plates will rapidly collapse. The movement of electrons during the discharging of the capacitor will again result in a momentary surge of current (current will flow from the positive terminal of the capacitor and into the resistor). The figure below shows the direction of current flow during charging (i.e. the switch in position B) and discharging (i.e. the switch in position C). It should be noted that current flows momentarily in both circuits even though you may think that the circuit is broken by the gap between the capacitor plates! The charge Q (in coulombs) stored in a capacitor is given by: I is the current in amperes and t is the time in seconds. Charge Q on a capacitor is proportional to the applied voltage V, i.e. Q V. Direct Inverse Proportionality Maths Q = CV The constant of proportionality C is the capacitance. The unit of capacitance C is the farad F (or more usually  µF =10-6F or pF =10-12F), and is defined as the capacitance when a p.d. of one volt appears across the plates when charged with one coulomb. Capacitance is the ability of a circuit or object (i.e. in this case a capacitor) to store electric charge. Problem 1: (a) Determine the p.d. across a 4  µF capacitor when charged with 5 mC (b) Find the charge on a 50 pF capacitor when the voltage applied to it is 2 kV.

(Answer: 30V, 480  µC) A steady current of 10 A flows into a previously uncharged capacitor for 1.5 ms when the p.d. between the plates is 2 kV. Find the capacitance of the capacitor. (Answer: 7.5 µF) CAPACITANCE AND PHYSICAL DIMENSIONS (Conventional Parallel Plate Capacitor) The capacitance of a capacitor depends upon the physical dimensions of the capacitor (i.e. the size of the plates and the separation between them) and the dielectric material between the plates. The capacitance of a conventional parallel plate capacitor is given by: Where, C = Capacitance, unit of measure farads (F) ÃŽÂ µ0 = Permittivity of free space or the free space constant (8.85 x 10-12 F/m) ÃŽÂ µr = Relative permittivity of the dielectric medium between the plates (ÃŽÂ µr has no units as it is a ratio of density material/vacuum) A = Area of one of the plates (m2) d = Thickness of the dielectric or separation between the plates (m) In order to increase the capacitance of a capacitor, many practical components employ multiple plates as shown. Ten plates are shown, forming nine capacitors with a capacitance nine times that of one pair of plates. Such an arrangement has n plates then capacitance C à ¢Ã‹â€ Ã‚  (n -1). Thus capacitance is then given by: Problem 1: A ceramic capacitor has an effective plate area of 4cm2 and separated by 0.1 mm of ceramic of relative permittivity 100.

[Answer: 1.67] CAPACITORS CONNECTED IN PARALLEL AND SERIES CAPACITORS CONNECTED IN PARALLEL The figure above shows three capacitors, C1, C2 and C3 connected in parallel with a supply voltage V applied across the arrangement. (Note: just like resistors in parallel, the supply voltage V is the same across each parallel capacitor) V = V1 = V2 = V3 When the charging current I reaches point A it divides, some flowing into C1, some flowing into C2 and some into C3. Hence the total charge QT (i.e. QT= I x t) is divided between the three capacitors. The capacitors each store a charge and these are shown as Q1, Q2 and Q3 respectively. Hence, But, QT=CV (where C is the total equivalent circuit capacitance) And, Q1=C1V Q2=C2V Q3=C3V Therefore, CV = C1V + C2V + C3V (where C is the total equivalent circuit capacitance) Dividing throughout by the common V giving, C = C1 + C2 + C3 à ¢Ã¢â€š ¬Ã‚ ¦Ãƒ ¢Ã¢â€š ¬Ã‚ ¦. + Cn The equivalent capacitance of a group of parallel connected capacitors is the sum of the capacitances of the individual capacitors. CAPACITORS CONNECTED IN SERIES The figure above shows three capacitors, C1, C2 and C3 connected in series across a supply voltage V. Let the p.d. across the individual capacitors be V1, V2 and V3 respectively as shown. Let the charge on the plate a of the capacitor C1 be +Q coulombs. This induces and equal but opposite charge of -Q coulombs on plate b. The conductor between plates b and c is electrically isolated from the rest of the circuit so that an equal but opposite charge of +Q coulombs must appear on plate c, which, in turn, induces an equal and opposite charge of -Q coulombs on plate d, and so on. Hence when capacitors are connected in series the charge on each is the same. QT = Q1 = Q2 = Q3 In a series circuit: V = V1 + V2 + V3 (Similar to resistors in series) Since, then (where C is the total equivalent circuit capacitance) Dividing throughout by the common Q giving, (Where C is the total equivalent circuit capacitance) For series connected capacitors, the reciprocal of the equivalent capacitance is equal to the sum of the reciprocals of the individual capacitance.

The manufacturer specifies this voltage. The limit is necessary so that the field strength in the dielectric does not exceed a value that would cause the dielectric to breakdown and loose its insulating properties. The figure quoted by the manufacturer for a capacitor is also known as the dielectric strength and will be in volts per metre.

[Answer: (a) 1.593 µJ (b) 5.31 µC/m2 (c) 600kV/m] D.C TRANSIENTS Networks of capacitors and resistors (known as C-R circuits) form the basis of many timing and pulse shaping circuits and are thus often found in practical electronic circuits. When a d.c. voltage is applied to a capacitor C and resistor R connected in series, there is a short period of time immediately after when the voltage is connected that the current flowing in the circuit and voltages across C and R are changing. These changing values are called transients. CHARGING A CAPACITOR The figure above shows a series connected C-R circuit. When the switch S is closed, then by Kirchhoffs valotage law: V = Vc + VR The battery voltage V is constant. The capacitor voltage Vc is given by, The voltage drop across R (i.e. VR) is given by, Hence at all times: At the instant of closing S (i.e. initial circuit condition), assuming there is no initial charge on the capacitor, Q is zero (i.e. Q0), hence Vc is zero (i.e. VC0). (Note: From equation Vc = Q / C). Thus from equation V = Vc + VR, V = 0 + VR (i.e. V = VR = IR) A short time later at time T1 seconds after closing S, the capacitor is partly charged to, say, Q1 coulombs because current has been flowing. The voltage VC1 is now, If the current flowing is I1 amperes, then the voltage drop across R has fallen to VR1 = I1R volts. Thus from equation V = Vc + VR A short time later still, say at time T2 seconds after closing S, the charge has increased to Q2 coulombs and VC has increased to, Since V = VC + VR and V is a constant, then VR decreases to I2R. Thus VC is increasing and I and VR are decreasing as time increases. Ultimately, a few seconds after closing S (i.e. at the final or steady state condition), the capacitor is fully charged to, say Q coulombs, current no longer flows, i.e. I = 0, and hence VR = IR = 0. It follows from equation V = Vc + VR that V = VC. Curves showing the changes in VC, VR and I with time are shown below. The curve showing the variation of VC with time is called an exponential growth curve and the graph is called the capacitor voltage / time characteristic. The curves showing variations of VR and I with time are called exponential decay curves, and the graphs are called resistor voltage / time and current / time characteristics respectively. The name exponential shows that the shape can be expressed mathematically by an exponential mathematical equation, as shown below. Growth of capacitor voltage, Decay of resistor voltage, Decay of resistor current, TIME CONSTANT (à Ã¢â‚¬Å¾ TAU) FOR A C-R CIRCUIT As shown earlier, if a constant d.c. voltage is applied to a series connected C-R circuit, a exponential transient growth curve of capacitor voltage VC results as shown below. With reference to the figure below, the constant voltage supply is replaced by a variable voltage supply at time t1 seconds. The voltage is varied so that the current flowing in the circuit is constant. Since the current flowing is a constant, the curve will follow a tangent, AB, drawn to the curve at point A. Let the capacitor voltage VC reach its final value of V at time t2 seconds. The time corresponding to (t2-t1) seconds is called the time constant of the circuit, denoted by the Greek letter tau, à Ã¢â‚¬Å¾. The value of the time constant is CR seconds, i.e. for a series connected C-R circuit, (seconds) Where C is capacitance (F), R is the resistance (à ¢Ã¢â‚¬Å¾Ã‚ ¦) and à Ã¢â‚¬Å¾ is the time constant (s) DISCHARGING A CAPACITOR When a capacitor is charged (i.e. with the switch in position A), and the switch is then moved to position B, the electrons stored in the capacitor keep the current flowing for a short time. Initially, at the instant of moving from A to B, the current flow is such that the capacitor voltage VC is balanced by equal and opposite voltage (Kirchhoffs 2nd law), i.e. VC = VR = IR. Finally the transients decay exponentially as current is reduced to zero, i.e. VC = VR = 0. The transient curve representing the voltages and current are shown below. The equations representing the transient curves during discharge period of a series connected C-R circuit are: Decay of voltage, Decay of current, When a capacitor has been disconnected from the supply it may still be charged and it may retain this charge for some considerable time. Thus precautions must be taken to ensure that the capacitor is automatically discharged after the supply is switched off. This is done by connecting a high value resistor across the capacitor terminals. Problem 1: A capacitor is charg

Information Communication And Knowledge Of An Organization Information Technology Essay

Information Communication And Knowledge Of An Organization Information Technology Essay Coca-cola Company is the worlds largest beverage company which leading manufacturer, marketer and distributor of non-alcoholic beverage concentrate and syrups. It is distributed over 200 countries. It owns more than 400 brands in the world including the main brands like diet coke,fanta and sprite etc.coca-cola is the most popular and the largest selling soft drink in history as well as in the world. Today there are many competitive in the beverage field. Therefore each company should be more attractive than their competitive companies. Information,Communication and Knowledge help the company to achieve its strategic goal. Amoung them Information and Knowledge help in decision-making and taking effectively. According to the coca-cola system they consider as their customers,grocery stores,restaurants and mass merchandisers. So that it is very important to know the ideas of consumers and their complaints about the product. As a beverage company Coca-cola company needs to know what customers ideas about the taste of their products.For that it has to be collect data fro m the customers and process them into information. Even though information collected there is no use if they do not distribute for use in organizations activities. Communication is the processes which distribute information.It can be done in many ways. The roles of Information, Communication and Knowledge in Decision making. The role of Information Information is a powerful resource and a large expense for many organizations. Information management is the process of collecting information from one or more sources and the distribution of that information to one or more audiences.This maintains the data of an organization. The information system of an organization is essential for the day-to-day activities in an organization. The activities of organizations are mainly coordinated by information and communication. Information is said to be processed data. Data can be defined as the complete range of raw facts and measurements For examples; letters,numbers,symbols,sounds and/or images relating to the events in the organization or its environment. Data is collected and then processed into information.Therefore information can be defined as processed organized or arranged data which is meaningful to the person.Data itself has no meaning so it is not useful in decision making.But informations are useful in decision making. Information is necessary to convert the resources of an organization such as-people,materials, machines and money for use in the organizations activities. Organization needs information for many purposes. They can be categorized as follows; Planning Recording Controlling Measuring Decision making Planning-In this step information help to get an idea about the available resources,present market and competitors of an organization. Recording-The information which use in recording helps to manage the business properly because using recording historical details can be found easily. Controlling-Once a plan is implemented; its actual performance must be controlled. Therefore information requires checking whether activities are proceeding as planned or whether there is unexpected deviation from plan. Measuring-In this step information can be used to measure performances of business.This can be analyzed by collecting information on costs,revenues,volume,time scales and profitability. Decision-making-Information is very much important to make decisions within an organization. Good information should have following qualities; It should relevance to a users needs. It should be accurate. The information should be readily available within the time period. It should inspire the users confidence. It should communicate to the user clearly It should have effective cost. The role of Communication When data is processed the information is communicated immediately to the person who wishes to use it but if it is kept for later use then it must be stored and retrieved when required.So communication is a essential component in organization because it shows how information is sent and received within organizations.The way of transferring information is depending on the structure of the business.Like entrepersonal,pyramid,matrix and independent. In simple terms communication can be identified as the process of transferring or exchanging of information,ideas,beliefs and opinions between two or more parties. Therefore communication process helps to coordinate tasks and activities of the organization. In other words communication helps to coordinate tasks and activities in an organization to achieve its objective or objectives.Therefore effective communication is an essential component of an organizational success whether it is at the interpersonal,inter-group, intra-group,organizational or external levels.The communication performs an important role in facilitating decision-making.It provides the information that individuals and groups need to make decisions by transmitting the data to identify and evaluate alternative choices, from sources to decision makers. The role of Knowledge Knowledge is full utilization of information and data.It is also related with persons skills and experience.Knowledge is the information within peoples minds and it is a subset of information which has been extracted,filtered or formatted in a very special way. Knowledge management describes the process of collecting,storing and using the knowledge held within an organization.The knowledge is based on the meaningfully organized accumulation of information through experience communication or inference. Knowledge is very important in gaining competitive advantage for a business therefore organizations need to manage it as both object and process. Knowledge is the power source of an organization because knowledge can increase productivity and effecientcy of an organization.The goal of knowledge management is to improve the organizations ability to fulfill its core process more efficiently because knowledge can result in better decisions. Therefore knowledge of an organization; Increase productivity Lower costs of doing business Higher quality products,decisions and recommendations Information AND KNOWLEDGE NEED INTERNALLY and externally to improve Decision making and taking. What is Decision-making? Decision-making can be defined as a process which selecting the best course of action from among several courses of actions.This may be a solution for a particular problem or a making a choice to achieve a specified state of affairs.Within an organization decision is the point at which plans,policies and objectives are translated into concrete actions.Therefore the purpose of decision-making is to direct human behaviour towards a future goal.Decisions can be classified as structured and unstructured.The structured decisions are repetitive routine. They are programmed decisions. Unstructured decisions are non routine and if decision maker provides judgment it is called non-programmed decisions because it does not provide clear cut solution. Decision- making process Different people use different approaches in making decision.Diferent scholars have presented different series of steps of a decision-making process.Whatever stages are elaborated, the decision-making process should have four stages as; 1. Identification 2. Development 3. Selection 4. Implementation Identifying the problem and collecting Information are important in the identification stage, while developing and evaluating alternative solutions are discussed under the second stage, development.Selecting the best course of action amoung the alternative solutions under third stage and put decision into effect and provide report on the progress of solution in the final stage in decision-making.According to the decision-making process collecting information is very important. Decision-making comprises the whole process that involves decision makers upto the point at which the issue is decided.Decision-taking is the function or activity of the responsible authority as in the case of a manager deciding on a course of action. Recognize the need for a decision Define the problem Identification Collect data relevant to the problem Analyse the data and find the root cause of the problem Develop criteria for satisfactory solution Development Generate Alternatives Assess Alternative Selection Select an Alternative Get the authority and implement the chosen alternative Implementation Monitor the feedback Steps in the decision-making Importance of Decision-making Within an organization, different types of decision are taken at different levels.Generally the decisions which are taken by senior management will be affected the business as a whole, and decisions that affect only one aspect of the business will be taken by lower levels of management. David Jennings and Stuart Wattam stated decision-making as an activity that lies at the heart of management.This shows how important is decision-making to an organization. All the actions made by the organization are result of decisions made by the organization itself.Problems of an organization arises because of the limited resources. But to make the organization effective it has to use the available resources.Thus they need to improve their decision-making.On the other hand the competition faced by organizations is increasing day by day. The survival of an organization will totally depend on the quality of decisions they make every day.Organization is a sub system of a social system.Therefore organizations can not work independently because several other systems are interrelated to the organization. In the case of coca-cola company decisions which make at any managerial level is very important because it can be either increase or decease in the number of customers.The future of this type of companies totally depends on the their consumers.Therefore every decision has to be taken by thinking about the consumers. Strategies to improve Decision-making and taking by using Information and Knowledge internally and externally. Managers can improve decision-making by using information and knowledge internally and externally.Internal information is important for all management levels in their decision-making and taking in the organization.But this relate to activities or transactions performed within the organization, such as administrative tasks, the production of products and services or the sales of products. To improve internal information manager can; Establish a system for collecting data or measuring data such as measuring output,sales and cost Relying to some extent on the informal communication lines between employees. In an organization to improve the knowledge managers can improve the personal skills of the employees.They can organize seminars to improve the knowledge of the knowledge of employees. External information is the information that obtained from outside the business.It can be either official or unofficial sources.Normally these information concern about official areas (tax,regulations etc.), the economy,suppliers and customers.In an organization external information are very useful. It helps in effective decision-making because in decision-making it is very important to know customers ideas,complaints and choices.The information of official areas provide the current situation of the business world in political view.Therefore by collecting information and knowledge of the outsiders the organization can achieve their goal effectively and efficiently. STRATEGIES TO increase personal networking to widen involvement in the decision-making process. What is networking? Networking of a business is the process of establishing a mutually beneficial relationship between personnel including customers, stakeholders and experts.The purpose of networking is to increase business revenue by development of relationships that generate information, referrals, advice, support, energy and much more.The best business networking give rise to exchange business information,idea resources and is the most important skill to establishing a mutually beneficial relationships. For effective and strong networking it requires people to; Effectively communicate Be prepared and willing to share information Listening to the others Have good contact with others Exhibit curiosity Asking questions to show that they are interested in the subject Identifying people in jobs that can talk to and make enquiries of Sources of personal networking Personal networking includes both formal and informal network members.Personal networks can guide the self determined person.This is very important in decision-making.Personal networking helps to improve the productivity.As well as personal networking it is very important to keep in touch with any group or key individuals who can affect the work or the objectives of the organization. Stakeholder networking help to; Stay in touch with developments in area of work Get information which will help in the work Influence individual decision-makers Stakeholders can be internal ( all levels of managers and co-workers) or external(regulators, environmental and legal entities).Therefore stakeholders are clients, project managers and teams, contractors and sub-contractors, distributors and suppliers and everyone else with a stake in an outcome stakeholder networking is a key to business success. According to the stakeholder contacts it can be dividing into two types; i) Primary stakeholders- They are directly linked to the organization such as shareholders, employees, customers and suppliers. ii) Secondary stakeholders-They are indirectly linked to the organization such as the media, regulators and competitors. Good relationships with stakeholders can increase the stability of an organization. For example if it has good relationship between suppliers and organization they show optimal responsiveness to company needs. This is not easy to do. It needs time for people to know one another, build trust and deal with organizational issues Strategies to increase personal networking 1).Forming business relationships Establishing good relationships with stakeholders help individuals to go through to find and develop lasting interpersonal relationships. The relationships with stakeholders can improve by Attending the meeting or events of other organizations Use e-mail and the internet to network with national or international organizations Attending political and community events where key organizations and decision-makers will be present Attending conferences, seminars and consultation meetings The relationships with customers are very useful in decision-making because managers have to increase customer satisfaction and minimize their problems. For that they have to build good and smarter relationships with customers to identify their preferences and to develop trust. In this case complaints, errors and proposals of customer are very important. So they must be recorded. There should be any medium available to contact the customers such as Internet, through a call center or personal contact. Therefore in an organization the decision which making by the ideas of customers are more powerful in achieving their goals. Not only the customers relationships supplier relationships also very important. 2).Networking direct or using media as an intermediate Based on the relationship of trust someone can be use as a referral in the process of networking. It is the most fundamental act in networking. Professional networking groups are the best referrals. They meet at regular times at a specific place and take decisions. 3). Formal and informal networking 4).Networking through trustworthy relationships and confidentiality Every individuals in an organization link together through trust and relationships. Therefore networking through trust and confidentiality is very important. Development of a communication process to improve the decision-making and organizational knowledge Process of communication Communication can be thought of as a process or a flow. Noise/barriers Receiver Decoding Channel Encoding Source Message Message Message Message Feedback Communication flows from one person or group to another and then, via feedback to the original person a group making a closed loop or cycle. Elements of the communication process are; i. Communication source/sender- The person who has message to communicate. ii. Message- The message can be identified as what is communicated. It is the subject matter of the communication. iii. Encoding-Encoding is converting a communication message to a symbiotic form. iv. Channel-The channel can be defined as the medium through which a communication message travels. Examples; Telephone, Letters, Radio etc. v. Decoding-Decoding is translation of the symbols in message into form that can be understood by the receiver. vi. Receiver- The receiver is the object to whom the message is directed by the communication source/sender. vii. Feedback-Feedback is the check on how successfully the communication source/sender has been transferring his/her message as originally intended. It is necessary to ensure that the receiver has received the message and understood it in the same sense as communication source/sender wants. viii. Noise/Barriers-Noise is external distances in the communication process.It is very important to note about noise. The result of this noise is that the message received is not the message transmitted by the communication source/sender. The types of communication processes are; Meetings and conferences Workshop and training events Internet and e-mail Written Telephone Video conference Communication process of coca-cola company They use ICT (Information and Communication Technology) to communicate both internally and externally.ICT has enabled 24 hours- 7 days global communication. This includes communication with; Employees-They use Facsimile (Fax) as the tool to contact the employees because most employees have fax machines I their office. Management-The pagers and Fax-machines help them to contact. Customer-Coca-cola company use only e-mail to communicate customers. They could send different product or new sales etc. Distributors of Coca-cola- They use video conference for the communication The existing processes of communication in Coca-Cola Company are: Internet and E-mail Video conferencing Facsimile(fax) Internal ICT communication in Coca-Cola Company E-mail-This is very fast way to send information and it save lot of time both sender and receiver. The staff of the Coca-Cola Company has their own program which is installed in their computers to tell them once they have received e-mail. Using email message can be sent to multiple recipients easily and can be forwarded on to others. Fax- This allows people to have copies of document they may require and sent the message. Enables messages to reach remote locations quickly but complex images in he faxes are not clear. Pagers-This allows people to received information whenever they are and whenever they need but long messages cannot be sent through this. Mainly executives use pagers in business. Video conferencing-This cannot use by all companies. Through this people from different countries allow to talk one another and listen to what is being said. This type of communication is very effective in the communication because it allows transmitting pictures as well as voices. External ICT communication in Coca-Cola Company Fax use to contact the external suppliers and suppliers are the only people who do fax them externally. This type of communication process saves money and the time. Improvement to ensure greater integration of communication They can use conversation also as a tool.This is unstructed and a discuss a wide range of topics. In decision making meeting are very effective communication tool. Coca-cola Company is world wide company .here only top level managers and directors can meet and take decisions. This allows expressing multiple opinions and they can be discussed and resolved wide range of issues. This type of communication tools can be used in long term decision-making and taking but for instant decision making they can use telephone. This is good way of communication that does not required a written record and conference alls allow multiple participants. Workshops and training events can be used to improve employee Knowledge. Through that they can improve organizational knowledge. Those types of methods can be used country vice. Personal-Interpersonal skills should be improved.Interpersonal skills involve inspiring,motivating,leading and controlling people to achieve objective/objectives. Interpersonal skills can be defined as skills use in interactions and relationships between two or more people. Good interpersonal skills can assist in Motivation,Communication,Team working and Team building and customer care. The role of Knowledge MANAGEMENT (KM) plays in managing organization strategically As indicated in the role of knowledge , Knowledge Management describes the process of collecting,storing and using the knowledge held within an organization.It is basically focus on organizational objectives such as performance,competitive advantage and continues improvement of the organization through the improvement and sharing of organizational knowledge management throughout the organization.Therefore knowledge management is not a technology pr computer thing and it depends on the human skills. Knowledge management use to identify,create,represent and distribute insights and experiences in an organization. These are help in managing organization strategically.

Airships INDEX PROLOGUE 2 TYPES OF AIRSHIP 2 RIGID AIRSHIP 2 NONRIGID AIRSHIP 3 HISTORY OF RIGID AIRSPS 3 HISTORY OF NONRIGID AIRSHIPS 4 AIRSHIPS TODAY 5 HINDENBURG 6 HINDENBURG DISASTER 7 PROLOGUE An airship is a type of lighter-than-air aircraft with propulsion and steering systems, it is used to carry passengers and cargo. It obtains its buoyancy from the presence of a lighter-than-air gas such as hydrogen or helium. The first airship was developed by the French, called a ballon dirigible, it could be steered and could also be flown against the wind. TYPES OF AIRSHIP Two basic types of airship have been developed: the rigid airship, the shape of which is fixed by its internal structure; and the nonrigid blimp, which depends on the pressure created by a series of air diaphragms inside its gas space to maintain the shape of its fabric hull. Inventors sought to combine the best features of these models in a semirigid type, but it met with only limited success. Today only the nonrigid airship is used. Rigid Airship The rigid airship's structure resembled a cage that enclosed a series of balloons called gas cells. These cells were tailored to fit the cylindrical space and were secured in place by a netting that transmitted the lifting force of their gas to the structure. Each gas cell had two or more valves, which operated automatically to relieve pressure when the gas expanded with altitude, the valves could also be operated manually so that the pilot could release gas whenever desired. Also on board was a ballast system that used water as ballast. On the ground this ballast served to make the airship heavier than air. When part of it was released, the airship ascended to a cruising altitude where the engines supplied propulsion, and further ballast could be released to gain more altitude. As fuel was consumed, the airship became lighter and tended to climb. This was countered in hydrogen-inflated airships by simply releasing gas into the atmosphere. The method was uneconomical, however, with helium-inflated airships, and they were therefore equipped with ballast generators, apparatuses that condensed moisture out of the engines' exhaust gases to compensate for fuel that was consumed. But this ballast-generating equipment was expensive, complex, heavy, and difficult to maintain and was thus one of the most serious disadvantages of airships filled with the safer but more expensive helium. Nonrigid Airship In contrast to the rigid airship, the nonrigid blimp has no internal structure to maintain the shape of its hull envelope, which is made of two or three plies of cotton, nylon, or dacron impregnated with rubber for gas tightness. Inside the gas space of the hull are two or more air diaphragms called ballonets that
