Goodyear Tire and Rubber Company

The Goodyear Tire and Rubber Company was founded by Frank Seiberling in 1898 on the Little Cuyahoga River in Akron Ohio. He borrowed thirty five hundred dollars from his brother-in-law to start the company. The company was named after Charles Goodyear who discovered the rubber vulcanization process in 1839. The company started to build their first factory in 1902 in Akron. In 1903 Paul Litchfield, a factory manager received a patent on the tubeless tire. In 1904 the company became a leader in automobile, carriage, and bicycle tires. In 1909, the company became involved in making airplane tires. Goodyear employs 73,000 people in 22 countries and operates 53 facilities globally. Goodyear Tire and Rubber Company’s mission statement is â€Å"To increase the value of our brands for everyone with market driven innovation, delivering the highest quality tires, related products and services, for our customers and consumers†. Strengths Goodyear has evolved as a leader in tire manufacturing and retreading across the globe. The company is the third largest tire company in the world with revenue surpassing twenty billion dollars. Goodyear is the best-selling tire in North America. Goodyear has very strong growth potential in all markets. This is a positive strength because competition is fierce and there is no room for error in the tire business due to the low profit margins on tires. Goodyear remains very profitable despite competition and that has Goodyear in a strong position for future plans and innovations. Goodyear has a strong liquidity position in the market. In the last couple of years Goodyear has advanced their position and had strong revenue streams to bolster their short and long term goals. Over the first three months of 2013 Goodyear’s revue was at a record 5. 5 billion dollars. Goodyear managed to achieve this even when raw materials and weaker demand was present. This demonstrates that Goodyear is financially sound, beating out competition to remain on top of tire industry and also proves its positive leadership and goals are on target in today’s market. Weakness One of Goodyear’s weaknesses is Debit. While Goodyear is seeing a rise in revenue and profits they still carry a large debit from recent years. On April 19th, 2012, Goodyear Tire and Rubber Company announced that it has completed a refinancing package of its U. S. credit facilities. These changes include increasing the company’s existing 1. 5 billion dollar existing revolving credit to two billion dollars and the maturity date has been increased to 2017. The company’s pre-existing 1. 2 billion dollar loan was extended until 2019. This is good news for Goodyear but still leaves them with a lot of debit to reduce in the future. They should be able to reduce this debit with the strong earning they are making and with new introductions of tires coming to market at this time. Another weakness of Goodyear is weaker overseas demand. As most of Europe is in a recession and many countries have severe unemployment, tire sales are down. This not just a problem for Goodyear but for all tire manufactures. Goodyear must analyze their overseas market strategy and take new measures to improve sales and remain profitable. Once a strategy can be put in place to remain a strong contender in Europe, Goodyear will see positive gains once again. Goodyear can minimize losses by reducing inventory and plant operation costs to make it more efficient than ever to keep their presence and name recognition at the forefront in the tire industry. Opportunities Goodyear has many opportunities to expand and gain market share worldwide. The Asian market is growing leaps and bounds and more people are able to purchase vehicles than ever before. The opportunities in these markets are quite great, and Goodyear will be there. With a solid global strategy, including manufacturing plants overseas, Goodyear is in a solid position with a large market presence already. Goodyear realizes the expanding market in Asia and is attacking on all sides with marketing and rebate campaigns to capitalize on the growth that is there for the taking. If Goodyear stays aggressive, they will surely reap the benefits. Another opportunity for Goodyear has been their new innovation centers in Akron Ohio and Colmer-Luxembourg. These new centers are developing new tires that are being highly praised and wanted, like the new Goodyear Assurance fuel Max tire that has 27 % less rolling resistance than conventional tires. The new Ultra grip 8 has more and stopping power than any tire on the market. With these new innovations and slim line operational costs, Goodyear is poised to be a market leader and very possibly will move up from the number three position they currently hold, and with the way the company is being run at this point, that is a definite possibility. Threats The highly competitive market is a big threat to Goodyear on all accounts. Bridgestone is the largest tire and rubber company in the world with sales over 35 billion. Michelin Tire Company is the second largest tire company in the world and both of these companies are threats to Goodyear in sear size and operation. There are other tire manufacturers, but these two are Goodyear’s biggest threats today. These large companies have great leadership and facilities to have the positions in the world market that they do and are very competitive in nature. These companies can lower prices to gain market share without making money for a short time and cut Goodyear’s market down, affecting the profits at Goodyear. Has this been done? Well nobody is pointing fingers, but there have been some fierce tire sales to accomplish increased market sales. Other threats that Goodyear faces are the lower cost tire manufactures. Other leading tire manufactures are selling tires at lower prices to gain a foothold in the market. These tires are good tires, but may lack the quality and reliability of a Goodyear tire. However with a tight economy, people sometimes will go with a cheaper tire to save money even if the tire will not give them the mileage and quality of a Goodyear. These companies can affect the over market share and profit at Goodyear. At a time when things are tough, people may choose these lower cost tires over Goodyear’s product, but Goodyear also has lower cost tires on the market to combat this, such as Dunlop and Kelly-Springfield brands. Summary Goodyear Tire and Rubber Company can capitalize in any market for tires, from high performance tires to lower priced economical tires. Goodyear has strong liquidity, multiple manufacturing plants and retreading facilities around the globe to compete in a very competitive market and has done well in the last couple of years in reducing operational costs and offering tire rebates, to place them in a great position for future growth. If Goodyear holds to its mission statement of delivering high quality tires at a great value, Goodyear will continue to prosper. References Goodyear Corporate website (2012).

Women: Rhetoric and Daniel Defoe

Romela Deguzman Women back then were seen inferior to men. They were labeled delicate, dependent, ignorant, or weak. Their central aim was only marriage but most intriguingly, education was deprived from women because of their sex. Mary Wollstonecraft and Daniel Defoe, both renowned writers wrote essays that demand justice and fight for the education of women. They believed they were capable and as intelligent as men. Wollstonecraft and Defoe created outstanding pieces known for its strength and most importantly its effectiveness to deliver their message across.Mary Wollstonecraft wrote the essay â€Å"A Vindication of the Rights of Woman† on 1792. She used rhetorical devices such as counterargument and analogy to prove her point. For example, one of the counterargument she uses is â€Å"†¦the female in point of strength is†¦inferior to the male†¦This is the law of nature†¦Ã¢â‚¬  pg. 640. She agrees that women are not as physically strong as men but argue s that they could still be as educated and talented as them. She also used analogy such as â€Å"†¦like the flowers which are planted in too rich a soil, strength and usefulness are sacrificed to beauty†¦Ã¢â‚¬  pg. 639.In this analogy, she is trying to express that women are being used for adornments just like flowers; but they shouldn’t allow themselves to be objects of adoration but use their morals and intelligence to match men. With the help of rhetoric, her message about women was effectively delivered. Daniel Defoe, the author of â€Å"The Education of Women† also used rhetoric to convey his message about giving women equal education as men. One of the devices he employed was analogy. â€Å"The soul is placed in the body like a rough diamond; and must be polished, or the luster of it will never appear† pg. 48. He is trying to say that everyone is valuable and unique just like a diamond, but we need education to rise or bring out the best of us. Also you can read Rhetorical Devices in Night Walker by Brent StaplesWomen need education to polish their souls. Defoe also used rhetorical questions such as â€Å"†¦what they can see in ignorance, that they should think it a necessary ornament to a woman? † pg. 648. Defoe engages the reader through this question by letting them understand that there is nothing to be proud of about ignorance and should not be given to omen. He clearly points out that education is crucial for both men and women. Rhetorical devices such as analogies, rhetorical questions, or counterarguments strengthen Defoe and Wollstonecraft’s essay by engaging readers. It successfully allows readers to see their point of view in different images they could relate to, and openly addressing arguments. Rhetoric made their delivery effective and most importantly persuasive, invoking action and change.

Motivation - Methods of Motivation use to excel in a College program Assignment

Motivation - Methods of Motivation use to excel in a College program - Assignment Example Motivation may push a student to spend countless nights studying for a course to excel in the marketplace. Psychologists believe that human beings are not the same. Thus, it is important to understand different types of motivation to capture different type of people, personality, and character. People are different on the way they perceive or view things, thus it follows that motivation has to be different. The three methods of motivation used to excel in college program include incentive, change, and extrinsic motivation. Primarily, incentive motivation is a strong force used in the learning institution. This method involves rewards. Through incentive motivation, students believe that they will obtain rewards for working hard or doing something. This motivates them to do everything they can to attain certain goals. This method of motivation bases its argument on the fact that human beings need to attain their set goals and objectives. To Anderman & Anderman (2010), learning institut ions utilize incentive motivation to reward the best performing or well-behaved students. By offering rewards, the management hopes to increase their performance and motivate their students to work harder in school programs. It is crucial to note that, there is high morale and motivation when people are working as a group in a given task. A continuous interaction in college programs increases friendship, unity, and mutual association. Motivation and morale help students to accomplish school programs faster and at an easy pace. For instance, incentive motivation may trigger students to work as a team and in turn creates a healthy competition. Teamwork or group discussion may help students to compete with each other and excel in all ways. It may also boost satisfaction and a sense of belonging. According to Karabenick & Urdan (2010), change motivation is a strong medium used to excel in college program. Sometimes, students, teachers, and other workers may do things to bring changes in the immediate environment. Change motivation pushes an individual to work tirelessly, hoping that one-day things will be better in their immediate environment. It is important to note that, change motivation help students to be tired of how things are and thus, think of a program to improve the entire environment. People are more likely to succeed when they understand their need to bring value to their organization. In the school set-up, external and internal factors that can sustain, intensify, start, or discourage bad behaviour. At this point, internal factors include human characteristics that trigger certain behaviours in the learning environment. For instance, students are fearful or confident when they approach new tasks. However, they are motivated when they live in a pleasant environment that fosters positive behaviours. It is crucial to understand that, external factors can affect learning conditions and personal development. For instance, certain schooling practices can h inder or promote motivations. These features include peer groups, classrooms, instructional practices, and school activities (Malloy, Marinak & Gambrell, 2010). At this point, helpful instruction may motivate a student to have good conduct. Change motivation is crucial in the school set up as it shapes students’ ability to learn experiences at school and in the large

Imagining the Impossible and Daring to Fight for it Essay

Imagining the Impossible and Daring to Fight for it - Essay Example I understood the meaning of this slogan only when we tried to start a student organization to fight against the injustices of capitalist society. The collective formed from the student organization gave us hope to dream for a brave new world with lesser exploitation and lesser oppression. It not only gave us hope but also taught us to find hope from ourselves. We realized many things which previously did not dare to imagine. We understood that we are not only the inheritors of an epoch which brings all the barbarities of past generations back to the brains of the living but also the trailblazers of a new society which is suffocating in the womb of the old. What we have in this society is merely a future of wage slavery that too is not undoubtedly because of the general capitalist tendency to keep a reserve army of proletariat. We are not only to interpret the world but also to change it since the interpretation of the world has no meaning if it is not for changing it. We are set to f ree ourselves from the society of, by and for wage slavery by knowing what is not yet known while assimilating what is already known as the wisdom of past generations. This is the only way for us to be grounded on theory and strive for the creation of a better world (not another world) by the means of concrete practice. In this society, the relations between human beings are predominantly determined by the relationship between things. Even things do not exist as things but as commodities. The end result is that human beings have also become commodities and the relationships between them are commoditized. As the members of most self conscious species, we at least deserve to have a world without the embarrassing stupidity of commercial advertisements. Nevertheless, we are aware of the tremendous transformations necessary for such a minute change. We do not have the illusion that students could lead the struggle against exploitation and

Organisation and change Article Example | Topics and Well Written Essays - 2250 words

Organisation and change - Article Example This brings loyalty from franchises and suppliers and they become more committed for the company's growth (Aswathappa, 2006). The company is however challenged by the need to continuously innovate to grow while operating flawlessly (Gubman and Russell, 2006). This report will find out how McDonald's is managing change to survive in the competitive business environment. The aim of this report is to present a consolidated change portfolio for McDonald's. The objective of this study is to find out the drivers of change for this fast food joint and this will be achieved by P.E.S.T and. Force-field analysis. The objective of the study is also to identify and justify the type of change McDonald's is facing. In addition, the report will present the process of managing change within McDonald's by using relevant change models. A number of books, journals and magazines have been used to collect information for preparing this report. The report will be divided into several sections and will also include a summary of findings and recommendations as well as conclusion. McDonald's has been asked by the US government to ensure the health of its customers. The company acknowledged that some of their suppliers were heavily using growth-stimulating antibiotics on chicken, beef and pork. These chemicals were proven to be injurious to human health and the authorities asked the food giant to help curb this practice. McDonald's has asked the suppliers from the meat industry to phase out the practice or lose business. The company is also working with People for the Ethical Treatment of Animals to improve the ways in which animals are raised and slaughtered (Greider, 2003). Economic The number of children also increased due to the rise in per capita income in the 1950s. This good economic period saw an increase in the number of suburbs in America and this encouraged the proliferation of chain restaurants such as McDonald's. The company opened restaurants in convenient locations where families in their cars could eat quickly the very affordable food (Debres, 2005). McDonald's restaurants were present in a large number of American suburbs by 1965 and the company avoided inner city locations until the 1970s. The company stepped outside US in 1967 and entered Canada and Puerto Rico. It then forayed into Europe and found out that it will not be successful if it continued to operate in the suburbs. There was no commercial development in the suburbs of Europe and the main markets were in the central cities (Debres, 2005). Social McDonald's popularity soared during the 1950s and 1960s when the Americans changed their lifestyle and began to enjoy the post-war period. More number of Americans decided to have more children and it became a common sight to see families with three or more children. McDonald's was oriented towards the family market and focussed on attracting small children, teenagers and young adults (Debres, 2005). Today, the customers visiting these food joints appreciate a sense of freedom they feel once they step into the facility. The young adults are very happy about the self-service concept and the minimal adult contact they have in

ACADEMIC PROFESSIONAL PRACTICE Assignment Example | Topics and Well Written Essays - 1500 words

ACADEMIC PROFESSIONAL PRACTICE - Assignment Example and Tang, reflective practice is like providing a fishing net for a hungry man that keeps him fed for the rest of his life while new teaching techniques is provision of food for a day without thinking about the man’s future (Biggs & Tang, 2007, p.43). The ‘net’ as the authors call it can be an inheritance for learners in order for them to share in the meals, as this research attempts to prove. In the analysis of how reflective application helps one to become a strategic learner, several things have to be understood. In this study, the definitions of reflective practice will become clear. The reader will understand the types of reflection, why they are important and how they affect strategic learning. The practical application of reflective analysis is helpful in moulding a strategic learner, this paper attempts to clarify the latter statement to the reader. Reflective practice has no single finite description; rather it is dependent on ones understanding of the multiple definitions by different scholars. According to Brookfield (2005), the practice of engaging in continuous self-evaluation and observation in order to know how one reacts to certain things is reflective practice. In the latter definition, reflective practice is not a way of self-refinement; rather it is a way of aiding the whole practice on an ongoing basis. According to Epstein and Hundert (2002), the continuous application of communication, technical skill, knowledge, emotions and reflection in daily practice is what best defines reflective practice. Epstein further states that the application of the earlier mentioned attributes is for the benefit of the individuals and the community of the practice. The final and most relevant application of reflective practice stems from Schon’s work in 1983 as cited by Lyons(2010).The definition states that reflective practice involves framing the problem of a given situation and determining the features to fix within the problem. After featuring

The Media in contemporary culture Essay Example | Topics and Well Written Essays - 1250 words

The Media in contemporary culture - Essay Example Of course, different people have various opinions on why the advertising is effective. For example, Berger, who wrote Ads, Fads, and Consumer Culture states advertising are a lottery, as it is still that nobody knows what advertisement will be effective and what will not. Berger adds that the advertisement executives believe that they waste half of money, spent on advertisements, but no one knows which half it is. (2000, p.2-3). Nowadays media is one of the most powerful instruments of forming the opinions of its consumers. Most of the marketing strategies that exist nowadays are built on the influences of the media. It is the irreplaceable instrument for selling things. Decades ago people bough what they needed, and their needs were dictated by their life conditions and financial status. It is nowadays that at first media creates the need in the specific product or group of products in people, and than they purchase the advertised thing. Thanks to the media people no longer buy things they need; they rather buy the attributes of the desired social status. Hirschman (2003) states that core societal values have an important role on advertising production and reception. Thus, to become fashionable, a product has to be promoted emphasizing its contribution to those societal values. Today media dictates people not only what they should buy, but also how they should behave, and what should they long for. Lindner, the author of the study, which analyzes the images of women in general interest and fashion magazine advertisements, states that: "advertisements often contain very subtle clues about gender roles and may operate as socializing agents on several levels. Because advertisements are publicly broadcast, the men and women portrayed are often perceived to represent the whole population, and men and women in the advertisements seem to accept these portrayed behaviors,

Luxury and convenience commodities Assignment Example | Topics and Well Written Essays - 1000 words

Luxury and convenience commodities - Assignment Example Now the building up of the habit to gain access to such convenience products happens to cite different alternatives or substitutes of such products to the consumer. The consumer of convenience products in addition to building up a relationship with the product category also tends to reflect a passion for a certain brand relating to the same. However in absence of the specific brand of such convenience product the consumer in the light of other possible alternatives tends to frequently switch over to other available brands. Hence the marketer of the brand of such convenience product needs to develop strategies to attract and sustain the consumers of such products in the global marketplace. The marketer needs to further understand that the total gamut of convenience products available in the marketplace can be generally sub-divided into three parts like Staple, Impulse and Emergency. Staple type of convenience products are refereed to such that tend to reflect a very large availability in the market like grocery commodities and even merchandises like petrol and diesel. Again Convenience products are categorized as being Impulse type where the consumers tend to get largely impulsive in gaining the same from market outlets. Thus commodities like chewing gum or chocolates are categorized as impulsive buys for they do not involve greater amount of planning. Similarly regarding Emergency products like safety aids, bandages and other repair and maintenance utilities and even medicines consumers desire to gain ready access to such in times of sudden needs. Thus in all the three categories of Convenience products it is observed that people procure such by chances or in needful situations thereby spending less time in planning and taking decisions (Baines, Fill and Page, 2011, p.294-295). Like convenience products where the marketer must focus on making every possible attempt to enhance the brand awareness of the same with the targeted consumers to reduce the chances of s witching over to other lower price alternatives strategies are also required to be in place for luxury or high priced merchandises. Consumers of luxury or high-priced products would not go for availing the same without rendering adequate planning. Consumers on the other hand would require gaining a large amount of information relating to the same before finally deciding on to purchase it from the market. Information gained substantially would help the purchaser in making adequate plans to gain the same. Thus herein the marketer is required to reinstate the benefits and advantages related to the brand of such luxury product in question to effectively lure and sustain the attraction of the person to the particular brand (Baines, Fill and Page, 2011, p.296). Management of Online Branding Activities for Luxury and Convenience Products With the development of internet and possibly of social networking platforms the marketing activities of producers and marketers of both convenience and l uxury commodities have gained far flung changes. Marketers of such products have come to acknowledge the fact that the emergence of internet has contributed to the birth of a global marketplace wherein a large number of consumers and buyers are found to mutually exist for different categories of products. Herein the online marketer in order to

Introduction - Effects of indignisation policy on entrepreneurship in Essay

Introduction - Effects of indignisation policy on entrepreneurship in Zimbabwe - Essay Example The governments across the world are recognising the importance of entrepreneurship for the growth and success of an economy. Nevertheless, various factors are determined to influence the growth and development of entrepreneurship within a nation. These influencing factors are generally bifurcated into two groups, which include external factors and internal factors. External factors such as labour market conditions, economic climate, legislations, infrastructure access to market and government policies are ascertained to have profound impact on the growth and development of entrepreneurship in the nations. On the other hand, internal factors such as motivational factors, funding, management capability, shortage of orders, marketing capacity and poor products and services among others lay considerable impact on entrepreneurship (Cooney, 2012). As far as women entrepreneurs in an economy are concerned, additional factors such as family obligations are also ascertained to have widesprea d impact on their growth and development (Das, 2001). In the recent years, the recognition of the importance of the entrepreneurship in the economic growth and development by the government bodies across the world has been coupled with formulation and implementation of numerous policies (Minniti, 2008). With the view to promote the economic growth and development, the government across the world are emphasizing on articulating support policies for the entrepreneurship development. Many government bodies have been motivated to formulate broad policies to provide ideal environment as well as needed resources for the growth and development of the entrepreneurs.

Consider the development Essay Example for Free

Consider the development Essay The word sonnet is the English translation of the Italian word sonetto, a little sound or song. A sonnet is a poem consisting of fourteen lines, ten syllables in English and Italian and generally twelve in French. There are three basic sonnet forms, the Petrarchan, which is an eight lined and a six lined (octave and sestet) sonnet with no rhyming couplet; the Spenserian, consisting of three quatrains and a couplet; finally the Shakespearian, consisting of three quatrains (four lines) and a couplet. There are different styles of sonnets all over the world. For example, France has its own unique structure that their sonneteers write in and the same with other countries. With all these different countries having different styles of writing that also means there are also different rhyming schemes. Reading sonnets is a great way of learning about different cultural aspects of life; for example during the seventeenth century the central theme of most sonnets was religion. During this time it gave people a great opportunity to learn about many different religions. The use of enjambment occurs in many sonnets. Enjambment is the running on of the thought from one line, couplet, or stanza to the next without a syntactical break The first sonneteer was Italian, his name was Francesco Petrarch. He was famous for a collection of Italian lyrics which include a long series of love poems. Petrarch wrote his poems about a lady called Laura, whom he met in a church. Laura became the central theme of his poetry. In total Petrarch wrote three hundred and sixty five sonnets. Petrarchs poems were meant to convey his love and devotion to the love of his life Laura. Sonnets moved to England in the sixteenth century. The seventeenth century saw the theme of sonnets change from love to religion. Donne is a good example of a sonneteer of religion. For two-hundred years a minute amount of sonnets were written. This was because they fell out of fashion. However during the nineteenth century sonneteers began to write about the theme of the natural world. William Wordsworth wrote poems such as Composed upon Westminster Bridge. War poetry became popular during the time of 1914-1918. This was because The First World War was happening at the time. War was on everybodys mind. The Poetry was read to the soldiers going off to war to motivate and encourage the soldiers to fight for their families and country. The poem Shall I Compare Thee written by William Shakespeare is about an unknown woman that Shakespeare compares to a summers day as summer is a picturesque time of year. The poem is written in the Shakespearian form. In the second line Shakespeare writes Thou art more lovely and more temperate This quotation informs the reader that although she cannot be compared to a summers day as she is more than the beauty of summer. Shakespeare writes Rough winds do shake the darling buds of Mai, this quotation is about the winds of summer; Shakespeare describes them as a type of rage. The woman could never be like summer as she is kind and caring. At the conclusion of the poem, (the rhyming couplet) Shakespeare writes So long as men can breathe or eyes can see, So long lives this, and this gives life to thee. This quotation informs the reader that she may die. However she will stay alive through the poem. The poem Composed Upon Westminster Bridge written in 1802 by William Wordsworth is about Wordsworth love of natural world and the city of London. The first line of the sonnet reads Earth has not anything to show more fair. In this quotation Wordsworth is sitting on Westminster Bridge looking across the beautiful city of London and is besotted with the picturesque view and feels the world has nothing to compare to it. William Wordsworth writes All bright and glittering in the smokeless air. This quotation informs the reader of the beautiful sunrise and how it glitters across the city. Wordsworth writes The river glideth at his own sweet will. This quotation means that the Thames has many bends on its path through the city of London and has not got a straight journey like other rivers. Wordsworth metaphorically states that the river glides freely. This sonnet is very popular and was voted 24th most popular poem in 1998. The mood of the sonnet is uplifting. The poem Death be not proud written by John Donne is about Donnes personal interpretation of death. John Donne does not fear death; he does not see it as a bad aspect in life. Donne writes Death, be not proud, though some have called thee mighty and dreadful, for thou art not so. This quotation informs the reader that some people may find death an awful, petrifying experience; however it is not, death is a new beginning. Donne writes Thourt slave to fate, chance, kings and desperate men, and dost with poison, war and sickness dwell. This quotation informs the reader that in life bad things will happen such as diseases and devastation. The mood of this poem is low key and dark. Donne writes One short sleep past, we wake eternally. This quotation informs the reader that after death our souls go to heaven and we awake eternally. John Donne was born in 1572 and died in 1631 at the age of 59. During Donnes lifetime this would have been considered an old age to die. There was a short life expectancy during this period because of all the disease and drug taking. The poem Peace written by Rupert Brooke is a war poem and it appealed to readers in the First World War as it informs them why their loved ones died in battle. Brooke was a very popular sonneteer as his poems would get the soldiers pumped up and ready for the gruesome activity that is war. Brooke encouraged people to be patriotic, to fight for their country and beliefs. Brook writes Leave the sick hearts that honour could move. This quotation conveys the fact that there are masses of casualties in a war just as there were in World War One. The sonnet The Vanity of his Passion written by Petrarch is addressed to his love, Laura. However he feels unreciprocated love. This could be for two reasons. Laura only exists in his mind or she is out of his league and could never fall in love with him. The sonnet is written in the first person; this is because Petrarch is expressing his love to Laura (There is a direct address to the lady). Petrarch uses many abstract nouns in his writing; he uses two in the title, vanity and passion. The reason for Petrarch using several abstract nouns is that it reflects the abstract nature of his love. Petrarch writes Throughout my song, by hopes and vain griefs bed; this quotation means that Petrarch recognises that he was vain ever to believe that she might ever love him. When Petrarch was younger he thought he was in love; he now realises what it means to be in passion drowned; Petrarch writes That worldly pleasure is a passing dream. This quotation informs that the love is short and cant last. His love is like a dream. The mood of the poem is very desolate as Petrarch wants something he is unable to achieve. In conclusion the central sonnet theme has not changed in hundreds of years, many are still written today. As time has progressed different forms have been introduced such as the Spenserian and the Shakespearian. My favourite sonnet is Shall I compare thee because Shakespeare uses many descriptive language associated with summer and his mysterious woman, this shows the depth of his love for her.

Spectrum Sensing and Spectrum Sensing Techniques

Spectrum Sensing and Spectrum Sensing Techniques Chapter 1.Introduction In recent years there has been an enormous growth in wireless communication devices and wireless users. The ever increasing demand for higher speed and reliability made researchers think about intelligent radios like Cognitive Radios (CR). But major amount of spectrum is available for licensed users. There are various communication bodies like the International Telecommunication Union (ITU), European Conference of Postal and Telecommunications Administrations (CEPT) also European Telecommunications Standards Institute (ETSI) who works on standards of communication that defines the use of spectrum for licensed and unlicensed users. 1.1 Background Spectrum is a valuable resource in communication. Over the past few years as the use of various wireless technology is increasing rapidly so we either need more spectrum or make efficient use of current spectrum to satisfy their needs. One way of making efficient use of spectrum is employing spectrum sharing technique. There are many spectrum sharing techniques available like energy detection, cyclostationary feature detector, and matched filter. Of the above technique matched filter and cyclostationary gives more accurate result but they are bit complex and computationally harder as compared to energy detection technique. Energy detection is the simplest of above three and computationally less complex. 1.2 Motivation Survey has shown that at any given time only portion of spectrum is utilized. According to a report published by FCC (Federal Communications Commission America) in 2003 has set a set of rule for efficient use of spectrum for licensed and unlicensed users. Also OFCOM (Office of Communications United Kingdom) has noticed the underutilization of spectrum. At any given time only portion of spectrum is utilized. Even if the system says there are no frequencies available, there is still some frequency available. These available frequencies are known as spectrum holes or white spaces. Some of the bands are completely occupied by users while some bands go unutilized. And that is inefficient use of spectrum. We must have noticed that in cases of emergencies like the train bomb blast in July 2006 in Mumbai, India cellular network actually failed to support huge amount of customer at the same time, this was also the case during 9/11 in USA. If we were having cognitive radios at that time peop les would have been able to talk to their families and inform about their safety. As we are moving from 3G (Third generation) to 4G (Fourth Generation) we need to make certain changes in our wireless technologies. Below shown is the measurement of 0 GHz to 6 GHz at Berkley Wireless Research Center (BWRC). 1.3 Aim and Objective This thesis emphasises on understanding Cognitive radios, the importance of spectrum sensing for todays world, the issues regarding the same. A simplified Matlab code is used to support our thesis. As the thesis follows you will find more about cognitive radios and spectrum sensing with a technique to generate white space at a specific frequency. The main objective of the thesis is to do survey on spectrum sensing and spectrum sensing techniques. Then do plan a model for the same. A model can be supported by a Matlab code. And after all this we need to analyse the model we suggested and further improvements that can be done in that. 1.4 Thesis Organisation Our thesis is organised as follows: Chapter.2 Literature Review This chapter begins with a brief history about cognitive radios .Which is followed by a detail explanation of Cognitive radios and spectrum sensing and some of the spectrum sensing techniques used. At the end of this chapter a business model for spectrum sensing and multi resolution of CR is given. Chapter.3 System Description This chapter basically deals with sampling and its importance to us. Also you will find technique to get your spectrum at specific center frequency under â€Å"generation of White Spaces†. Chapter.4 Simulation/Design Analysis As the name suggests, this chapter deals with simulation model and detail explanation of the code used for spectrum sensing using energy detection. In this chapter we have shown the output of the simulation used. Chapter.6 Future Work This chapter suggests some of the future work to be done with this thesis which could be useful for further research in this field. Chapter.7 Conclusion This gives the concluding part of the thesis. Chapter 2 Literature Review In this chapter we are going to discuss about the cognitive radios, like what are they and why are they so important to us. The chapter begins with a short history of cognitive radios, which is followed by a general discussion on OFDM, some of the challenges faced by cognitive radios in real environment, and also some of the applications of cognitive radios. We have tried to explain spectrum sensing in brief and the techniques used for spectrum sensing in todays world. Finally a business model for spectrum sensing is showed which is preceded by multi-resolution of Cognitive radios. 2.1 History of cognitive radios Dr. Joseph Mitola III was the first to introduce or propose the theory of Cognitive radios in 1999. According to Dr. Joseph Mitola Cognitive radios will be the radios that are smart and intelligent enough to find the available bandwidth in a spectrum. It will also have knowledge of right information that has to be passed to the user. And user does not have to take some extra effort for that. It is supposed to do this automatically. He has also mentioned in his PhD dissertation that CR is natural extensions of software defined radios. In 2002 the FCC published a report prepared by Spectrum Policy Task Force [SPTF] which says that majority of spectrum is underutilized. And there is actually is not shortage of spectrum but rather we need to make efficient use of the current spectrum. Also in same year 2002 Professor Cave from UK presented a report which speaks of the possibility of selling bandwidth to the user depending on their requirement. But it would not be fair to give unlicensed user allow to use licensed spectrum. So in December 2002 FCC issued a Notice of Enquiry (NOI) to see TV channel bands can be made available to unlicensed users. Then in 2003 FCC forms a set of rules and proposed interference temperature model for keep track of interference. Later in the same year Notice of Proposed Rulemaking (NPRM) tried to see into issues related to cognitive radio technology where it also pointed out Cognitive radios is a advanced technology which could help efficient use of spectrum by licensed users in own network and by sharing spectrum and with unlicensed users by negotiating when required. This encouraged many researchers in the field of cognitive radios. Major progress in cognitive radios took place in the year 2004, where FCC published NRPM which showed possibility of allowing secondary users to use licensed spectrum. FCC opened three bands for unlicensed users which are 6525 to 6700 MHz, 12.75 to 13.15 GHz and 13.2125-13.25 GHz. This allowed cognitive dev ices to transmit six times more. Also IEEE standards are working parallel to the FCCs. Spectrum pooling system by Professor Timo A Weiss from Karlsruhe University Germany), OFDM based Cognitive radios by professor Ian F Akyildiz et al from GIT (USA) are some of the promising works in Cognitive radios. there are many researches are done, many still going on in Europe, Asia, and America, exploring various aspects of cognitive radios. In Jan 2010 first call over a CR network was made in university of Oulu using CRAMNET (Cognitive Radio Assisted Mobile Ad Hoc Network). 2.2 Cognitive radio With the development of wireless communication devices and technologies in WLAN and WAN spectrum is becoming scarcer. Low frequency bands which are near few GHz are very scarce and highly congested. In current wireless system we are using fixed spectrum allocation scheme. In fixed spectrum allocation scheme a part of spectrum is owned by an operator. Unlicensed users are not allowed to use that spectrum. This leads to the problem of spectrum scarcity. Survey has shown that more than 50% of the spectrum is underutilized. This is where Cognitive Radio (CR) is comes into picture. CR is introduced to solve the problem of spectrum sharing. Cognitive Radios actually scans the spectrum and during scanning it looks for spectrum holes. The main objective of the cognitive radios is to look for opportunities or white spaces in spectrum band as quickly and as much as possible. And when we say opportunity, opportunity could be in time or frequency domain. Also when we locate this spectrum holes opportunistically we also need to vacant the occupied spectrum as soon as primary user comes back. Here primary user means the users whose spectrum we are using (licensed user) and secondary means the unlicensed users. Cognitive radio is a pattern for wireless communication technology in which either a network or a wireless node changes its transmission or reception parameters to communicate efficiently avoiding interference with licensed or unlicensed users. These altered parameters are associated with the active monitoring of several factors in the external and internal radio environment e.g. radio frequency spectrum, user behaviour. Cognitive radio can be said as next generation of software defined radio (SDR). They are flexible in terms of their transmission characteristics in terms of frequency, bandwidth, ISP which makes smart decisions to configure the SDR at any point in time to achieve a particular goal. By combining these two technologies makes a radio intelligent and flexible and which helps to adapt it to the variations in the environment, user requirements as per the other radio users. Adaptation to changes and requirements should lead to highly reliable communication whenever and wherever required, while making efficient use of spectrum. Good cognitive radio uses analysis done for long period to know about the environment and also his own behaviour. There are various parameters taken into account to decide transmission and reception changes, we can distinguish certain types of cognitive radio. The main two are as follow: Full Cognitive Radio : It is also known as Mitola radio in which every possible parameter which can be observed by a wireless node is taken into consideration to take decision Spectrum Sensing Cognitive Radio: It is the type in which only the radio frequency spectrum is considered. And Depending on the parts of the spectrum available for cognitive radio, we can distinguish as: Licensed Band Cognitive Radio: It is the type in which cognitive radio is capable of using bands assigned to licensed users, apart from unlicensed bands, such as U-NII band or ISM band. Unlicensed Band Cognitive Radio: This can only utilize unlicensed parts of radio frequency spectrum only or the bands which are free to use. 2.3 About OFDM OFDM stands for Orthogonal Frequency Division Multiplexing. It is generally a type of Frequency Division Multiplexing (FDM) rather a special case in FDM. What makes it special is its orthogonal behaviour. Now the word orthogonal basically means mutually independence. When we say A is orthogonal to B, we mean that A has no vector in direction of B and vice versa or in other words A and B is mutually independent. Or the integral of two signals over one period is 0. In OFDM a single signal is first multiplexed and modulated independently to create orthogonal signals. This means the signal is first divided into number of smaller streams and then modulated further before transmission. For example imagine a slicing of cheese and grilling or cheese. Slicing is like FDM where whole data is sent in a bunch and grilling is like OFDM where the data to be sent is first divided into smaller data and then processed to transmit further like OFDM. Figure shown below is one more way to understand the concept of OFDM. On the left hand side is a big container which carry whole bunch of data at one time and take it to the destination. And on right hand side is four smaller containers where each carry smaller portion of data and take it to the destination. These smaller containers can be assumed as sub-carriers. And in case of OFDM they are orthogonal sub-carriers. The main advantage over here is that even if some of the cheese is lost during grilling, still we have not lost all the cheese. In OFDM input data with high data rate is first passed thorough serial to parallel converter. This parallel divided data is then modulated on individually. And parallel to serial conversion is done before transmission. This parallel divided data is our sub-carriers. These sub-carriers must be orthogonal. 2.4 Cognition cycle Above figure shows the rough model of Cognition Cycle. It reads the surrounding environment and makes decision accordingly. When we say decision we mean cognitive radio sense the requirement or urgency that may be in terms of changing a channel or churning from one technology to another depending upon the scenario. There are different stages where it observes the environment, learns it and then plans its action make required decision and then execute its plans. It is much like a radio with a power of thinking which was not been able before. The figure below shows the cognitive radio architecture suggested by Dr. Mitola. 2.4.1 Some important terms 2.4.1.1Wireless Environment/Outside world- It refers to a communication environment that includes any communication devices and the frequency bands they are working in. 2.4.1.2 Spectrum sensing- It is the technique used by cognitive radios to sense the spectrum. This action involves finding availability of white spaces or spectrum holes in the spectrum. 2.4.1.3 Spectrum Management- It involves catching the best spectrum available so as to satisfy user communication requirements. Cognitive radios should decide on the best spectrum band so that it can meet the Quality of service required for all available frequency bands, therefore these functions are necessary for Cognitive radios. These management functions can be classified as: Spectrum analysis Spectrum decision Spectrum Mobility: It is defined as the process when a cognitive radio device exchanges its frequency of operation. Cognitive radio networks target to use the spectrum in a dynamic manner by allowing the radio terminals to operate in the best available frequency band, maintaining seamless communication requirements during the transition to better spectrum. Spectrum Sharing: providing the fair spectrum scheduling method. One of the major challenges in open spectrum usage is the spectrum sharing. It can be regarded to be similar to generic media access control MAC problems in existing systems 2.5Cognitive Radio Challenges Three main problems experienced by CR are as follows: Interference (Mainly because of Hidden Nodes). Security. Control. They are described as follows: 2.5.1 Interference and the Hidden Node Problem Ideally while designing a CR we should consider that it does not have any impact on existing radio users, but in practically some impact is expected. If a particular user have non-cognitive radios, it is essential to study and make a note that how they would be affected by the interference of CR, mainly with respect to sharing resources such as spectrum, time, space etc. CR adaptive nature could be difficult to predict and thus making it hard to control the behaviour of a CR which will concern for user who faces CR interference issue. In communication industry the main concern about CR is the hidden node problem. This scenario arises when a CR is not capable to detect an interference with any of non-cognitive radios within its range, not only because of CRs own spectrum sensing is ineffective but also due to some non-cognitive radios are hidden. For example, if a transmitting contemporary user is not in the range from the CR, its transmission power may not be strong enough at the CRs location, it may be reduce than the noise floor which makes it more difficult to get detected. As the CR might not be able to detect a transmission by a contemporary user and similarly unaware of availability of the receiving by a contemporary user. Consequently, if it is confirmed as safe to use the contemporary users frequency and CR starts transmitting, at the contemporary receiving end it will create interference. The CR may have a limited view of spectrum provided from wide spectrum measurements which may cause interference with the receiving user. The localised spectrum view denotes that a CR should be potential to find transmitting user those are communicating below the noise level, since the strength of the received signal is very weak at the CRs location. Similarly a situation can occur where the signal attenuate by distance, thus user transmission is blocked by obstacles such as buildings, towers, hills or mountains. For example consider a CR in a valley would have a limi ted picture of the surrounding radio environment, as compared to that if it were located on top of a hill. 2.5.2 Security Concerns CR may be vulnerable to malicious effect, resulting into unexpected or problematic behaviour of individual CRs or complete networks. This problem springs up from the potential to re-program CRs in an unauthorized way. Hacking or placing a vulnerable code, virus on a network might enable criminals to steal valuable information from a CR through electronically, fool a network operator into charging others for services or achieve potentially widespread denial-of-service. A considerable amount of regulatory work will require to be done to clarify who would be responsible for the various security areas of CR, software developers, manufacturers, network operators and CR users themselves may all have a role to play. The CR security issue is closely related to that of SDR, which already discussed and hence not repeated here. Instead, a brief summary of the issues is given. Downloading software updates over an air interface poses some specific problems for security. Several digital signatures will be required for each piece of downloaded software in order to meet likely regulatory requirements. Exactly who is necessary to authorize software downloads must be standardized before any large scale deployment of over-the-air updates can be realized. 2.5.3 Burden of Control and Regulatory challenges A CR in reality will have some effect on different spectrum users the compliance of these new radios is likely to focus on a Policy module defined within a CR, which will determine the boundaries of CR behaviour. It is important while studying CR; to consider how users would not be affected by interference from CR devices and the exact operation and nature of a proposed CR policy system must be understood carefully. It is likely to include a detail case study of the specifications and characteristics of all the contemporary users for a specific CR or complete network of CRs may share the resources. The effort in controlling CR devices, it is necessary to ensure their behaviour is properly or not, even in the case of faulty or tampered devices, that measures are quickly implemented to intense problems. This will involve policies and standards which are created in a universal digitally interpretable policy, so that all CRs can understand the same. Monitoring techniques and powerful alg orithms are required to enable detection and identification of bad CRs and in this way it provides traceability to find or determine who is responsible for the issue. In addition to these challenges, spectrum regulators and spectrum managers will require providing access to licensed spectrum in such a way that is traceable, transparent and highly dynamic. If CRs are allowed to cover international territory additional effort will be required, due to the necessity to provide and collaborate cooperation with other countries. Assuming that acceptable control of CR policy behaviour is technically possible and feasible, it may turn out to be such a great burden that it will be simply not economically viable and the benefits of CR are outweighed by this burden. 2.6 Important Applications for Cognitive Radio are Downloading of audio and video files on mobile handsets. This application requires moderate data rates and near-ubiquitous coverage. Emergency services communications: It requires interoperability and a moderate data rate with local coverage. Broadband wireless networking: Very high data rate required but CR users have option to accept limited coverage, e.g. hot spots. Multimedia wireless and sensor networking: Broad range of data rates may be required. 2.7 Spectrum Sensing Spectrum sensing is the process performing measurements on the part of spectrum and on the basis of measured data making a decision related spectrum usage. As the requirement and quantity of users is getting increased day by day, it is necessary for ISPs to have large amount of spectrum in order to achieve the QOS (Quality of Service). This leads the interest in unlicensed spectrum access and spectrum sensing is vital concept of this. In a situation where there are licensed user and any unlicensed exists, licensed user (primary user) is to be protected and no unlicensed user can interfere any licensed users operation and such cases Spectrum sensing is also useful to detect the existence or non existence of a primary user. Spectrum sensing is an important concept for exploring spectrum opportunities for the secondary spectrum usage in real-time. It detects the unused spectrum and shares it without any noticeable interference with other users. It is an important requirement of the Cogn itive Radio in order to sense spectrum holes. Detecting primary users is the most efficient way to detect spectrum holes. 2.8 Spectrum Sensing Techniques Available Spectrum sensing plays a vital role in cognitive radios. And the type of spectrum sensing techniques to choose more or less depends upon the spectrum sensing technique. A method such as energy detection proves to be one of the simplest of all, but it doesnt works well at low SNR, varying noise levels, fading. On the other hand technique such as Matched filters shows better performance, but they comes complex receiver design. We are going to discuss some of these techniques as we proceed further. 2.8.1 Matched Filter Technique This is the technique which takes minimum amount of sensing time. In this method of spectrum detection, receiver receives a pilot signal along with the data that is sent by the transmitter. A pilot signal is a single frequency that is used for synchronisation. All the secondarys those are struggling for spectrum should have knowledge of this pilot signal. There should` be tight timing synchronisation between primary and secondary. They are also required to know about the kind of modulation being used, pulse shaping. Also secondarys must have another receiver for every primary. This kind of techniques also fails when there is frequency offset. Examples of this technique are TV signals, CDMA with pilot, also used in OFDM. 2.8.2 Energy Detection technique This is the most simples of all techniques. In this the receiver has no knowledge of the transmitted signal. The receivers need not to have knowledge about the modulation type or any kind of pilot signal. Earlier energy detection was done with the help of a LPF (Low Pass Filter), Digital to Analog converter (D/A), and square law device that used to calculate the energy of the signal. Later it is done by making use of fast Fourier transform (FFT). This is known as periodogram method in energy detection. 2.8.2 Cyclostationary Feature Detection Signals are modulated with sine waves or cyclic prefix as in OFDM. And they are periodic. This periodic property of a signal helps it to be cyclostationary. This technique basically uses this principle of spectral correlation to detect the spectrum. Even if signals have similar PSD (Power Spectral Density) but they have do not have similar spectral correlation. 2.9 Multi-resolution for Cognitive Radio Sensing The concept of multi-resolution for Cognitive Radio can be applied with different methods but, the basic idea is the same. The whole spectrum is first sensed by using a coarse resolution. After this first step fine resolution sensing is done on a part of interested bands. In this way CR avoids itself from sensing the spectrum at one time and thus saving time and power. In this way, the sensing time is reduced and the power also been saved from unrequited computations. Also the multiple antenna architecture helps parallel processing and enables to reduce the sensing time. But, it increases the chip area and consumption of power which is not desirable. Also for coarse resolution sensing the mixer has to produce many frequencies and Also it should switch to one frequency for beginning the fine resolution sensing. If the signal is low pass signal then we can use fine resolution to scan the whole spectrum. Because low pass signal has low center frequencies and its sampling is doable. But for pass band signals it is not feasible to scan the whole spectrum. Because, for example say if we have some signal with center frequency of 850 MHz, it is not practically possible to do sample that signal. As according to Nyquist theorem sampling rate should be at least twice that of center frequency. Therefore it is practically not possible to sample a signal at 1600 Mega Hertz. 2.10 Business Model for Spectrum Sensing So far we have discussed about Cognitive radios and spectrum sensing in details. Since this is telecom, and telecom involves huge capital investment. One of the most costly things in telecom is getting the license itself and then comes the infrastructure and installations etc. Currently most of countries work on static spectrum allocation basis. For spectrum sensing to work we need some kind of regulation or set of rules that all will be ready to work with. A team from Brussels University has suggested a model for the same. The same model is discussed in brief below. This model is divided into four main categories. i. Ownership- Ownership simply means the ownership of license. One who has license is authorized to use particular band of spectrum. And if another licensee wants to share a spectrum then it will depends on parameters discussed below. If the operator is unlicensed then there is now issue of ownership. ii. Exclusivity- Exclusivity means whether or not a particular operator is exclusively assigned a band of spectrum. That will be issue of regulator to decide to exclusively assign a spectrum to a specific user. If it is assigned exclusively then nobody can access that band of frequency, and if not then those bands of frequencies will be available for sharing. iii. Tradability- Tradability means whether or not a terminal is allowed to switch between frequencies from different operators. If tradability is permitted frequency band or bands can be auctioned for sale or given on lease. iv. Neutrality- It is possible that some of frequency bands can be accessed by number of RATs (radio Access Technology) or may be limited to a particular RAT. If frequency bands are not available to number of RATs then that band need to address more issues, such as setting technical conditions to access the band and coordinating the cooperation between multiple technologies. Unlicensed: Unlicensed deals with the band of frequencies which are free to use, like ISM band. Common example for this is Wi-Fi which operates in 2.4GHz. This band of frequency is available to all and there is special condition to access this band. Single RAT Pool: This pool is related to a group of licensees which are not exclusively assigned any band of frequency and using same RAT. Multi RAT Pool: It is similar to Single RAT Pool except that it has multiple RATs. Single RAT Market: In this each operator is assigned with a separate frequency, but that can be accessed by the conditionally secondarys. Multi RAT Market: In this the operator is a licensee and is exclusively assigned with a band of frequency, and also with tradability. Flexible Operator and Static Spectrum: If a particular band of spectrum is exclusively assigned to an operator and without tradability. And if there is only one RAT, then it is known as Static Spectrum else Flexible Operator. 2.11 Survey outcome As per the literature review we concludes to use Energy detection technique for spectrum sensing as it is the fastest spectrum detection technique available and also it is simpler as compared to other techniques. There are many researches done in this field and many are still doing. Because of the survey we get knowledge about various techniques available in market. This led us to do a simulation model with one of the spectrum sensing technique. Now as far as selection of spectrum sensing technique is concerned, we selected Energy detection technique. The same could be seen in next part of the thesis which includes its design and implementation in simulation model. Chapter 3 Simulation Design 3.1 Sampling and Its Importance Sampling is a process of converting the continuous analog signal to a discreet analog signal and the samples signal is the discreet time representation of the original signal. If the message is coming from a digital source, then it is in the form to be processed by digital communication systems. But in real life not every signal is digital, message signal can be analog. In situation like these, we have to first convert the analog signal into discreet time signal, this is sampling. For this process to work well, sampling rate should be selected carefully or in other words it should satisfy Nyquist criterion. And Nyquist Criterion says that the sampling frequency should be at least twice the maximum frequency in signal. Fs ≠¥ 2fmax or T=1/ fmax Where â€Å"Fs† is sampling frequency, fmax is maximum frequency in the signal. T=Sampling period. Sampling is like reading a signal in analog form and taking its value at that instant of time. So more the samples we take better the resolution of the signal and, signal can be recovered more accurately. But if we take less number of samples, then resolution of the signal decreases. If we go on reducing the sampling rate, then times comes when it is difficult to recover the original signal from the sampled signal or in other words original information in the signal is lost. This is also known as aliasing. Aliasing is the effect which takes place if the signal is sampled less than twice the maximum frequency. 3.2 Types of Signal 3.2.1 Time limited signal- It is a signal which exists for only certain duration of time. Out of this duration, signal does not exist. A rectangular pulse of duration â€Å"T† seconds can be considered as time limited signal. x(t)=A †¦ for 0 3.2.2 Band Limited signals- It is a signal which has a frequency spectrum which exists only over a certain range of frequency. The value of signal outside this range of frequency is zero. Mod(X(f))=A †¦.-B 3.3 Sampling Of Low pass and Band Pass signal Low pass sampling theorem states that- a) A band limited signal of finite energy, which has no frequency components higher than W Hertz, is c

Impact of Jealousy on Relationships

Impact of Jealousy on Relationships Jealousy has crucial and far-reaching implications for persons who are involved in romantic relationships. According to Harris (2009), individuals in a romantic relationship, do at some point experience the feeling of jealousy. Among most definitions of jealousy, it is usually defined as an emotional response to the real or imagined threat of losing something of value from a romantic relationship (Salovey Rodin, 1985; White Mullen, 1989). Some researchers for example Anderson et al. (1995) view romantic jealousy as a positive experience. Having a jealous partner, can cause someone to become careful and avoid other relationships formation and thereby do not longer take his or her current partner for granted. Harris and Darby (2010) supported this conclusion by saying that â€Å"it alerts one to relationship threats and can motivate behaviors that protect the relationship† (p.547). Taking into consideration that the experience of jealousy may protect romantic relationships against potential threat, it is seen to coincide with evolutionary psychological perspective on relationships. From this approach, Buss (2000) argues that romantic jealousy is an adaptive emotion that helps those who are at the risk of losing their partner to a third party and thus must act to hinder the potential loss of the sexual reproductive benefits they gain from their partner. Thus in a way, jealousy may forestall a partners unfaithfulness and is therefore fundamental to relationship bettering goals of mate guarding and mate retention. Evolutionary psychology also predicted who is more prone to be jealous. In most couples, a partner may be more physically attractive, having good health and resources. They thus have the power to attract possible replacement partners than the other partner, which is known as the â€Å"fluctuating asymmetry† (Gangestad Thornhill, 1997). The less a ttractive partner experiencing jealousy in this context is believed to be adaptive in order to protect their relationship from being threatened by a rival and breaking. The study done by Brown and Moore (2003) is in line with this argument. Despite of its good side, there are several evidence for the dark side of jealousy. Barelds and Dijkstra (2006) said that in Western culture jealousy has a negative significance and is frequently seen as a socially undesirable emotion. Many of the empirical studies done in the past have also found that the common person tends to describe jealousy as a negative and bad emotion. For instance the study done by Sharpsteen in 1993 reveals that during the study when people were asked to determine the characteristics of jealousy, their answers were hurt, threatened, bad thoughts about other man and woman. In other words they identified the features of jealousy as negative only. According some researchers for example Hendrick and Hendrick (1983), the feeling of jealousy is not healthy and it is an evidence of deficit. Other researchers have associated jealousy with low self-esteem (Bringle, 1981), low self confidence ( Bunk, 1997), low generalized trust ( Buunk and Dijkstra, 2000), low empathy for others (Radecki Bush, Farrell, Bush, 1993), loneliness ( Rotenberg, Schewchuk Kimberley, 2001), a need for approval (Salovey Rodin, 1985,1989), neuroticism (Stieger, Preyss Voracek, 2012), depression (Tarrier, Beckett, Harwood Ahmed, 1989) and generalized hostility (Thomas, Miller Warner, 1988). On attachment basis, it was found that individuals who display insecure attachment style are more likely to feel jealous about their partner than those who have a secure attachment style (White Mullen, 1989, Sharpsteen Kirkpatrick, 1997, Guerrero, 1998, Harris 2009). The worst side of jealousy is that it can cause someone to become aggressive and violent towards romantic rivals. (DeSteno et al. 2006; Paul et al. 1993; Chiffriller Hennessy, 2007; Harris, 2003; Mullen 1995). All the studies cited above, under the definition of jealousy gives us evidence for the good and bad sides of romantic jealousy. However, most researchers now are in the favor of a multidimensional approach in order to clearly understand how jealousy is conceptualized and experienced. (Bevan Samter, 2004; Buunk, 1991, 1997; Buunk Dijkstra, 2006; Harris, 2009; Pfeiffer Wong, 1989; Salovey, 1991; Sharpsteen, 1991). Bringle et al. (2007) put forward the transactional model of jealousy, which is a multidimensional approach that defines two types of jealousy. First the suspicious type and second the reactive type. Suspicious type of jealousy comprises of feelings, behaviors and thoughts that are experienced when major cases that would usually arouse jealousy are absent. In addition, someone experiencing features like high levels of anxiety, insecurity about their relationship and doubt describes suspicious jealousy. The reactive type is however different from the suspicious type of jea lousy. This kind of jealousy occurs when one partner has learned that his partner has betrayed him or her. Suspicious jealousy is referred to internal individual factors like low self-confidence and insecurity, while reactive jealousy is related to exogenous factors that come from the relationship and society. Scholars Buunk (1991,1997), White and Mullen (1989) identified three components of jealousy: Emotional Jealousy, Cognitive Jealousy and Behavioral Jealousy. Emotional Jealousy Series of studies have concentrated on the emotional component of jealousy. Emotional jealousy comprises of an affective reaction to a real or an imagined threat to a valued relationship (Theiss Solomon, 2006). Emotional arousal embraces negative feelings such as anxiety, discomfort, anger, fear, insecurity, and upset (Guerrero, Eloy, Jorgensen, Andersen, 1993; Sharpsteen, 1993; Sharpsteen Kirkpatrick, 1997). Depending on the situations, emotional jealousy may also include feelings of sadness, guilt and envy (Guerrero, Trost, Yoshimura, 2005; White Mullen, 1989). Emotional jealousy refers to how someone feels when his or her partner is flirting with someone else, kissing or hugging someone of the opposite sex or how that person feels when he or she learns that somebody else is dating his or her partner. Cognitive jealousy Several studies have analyzed the role of cognition in jealousy, which includes the appraisal of threat to a relationship (Fitness Fletcher, 1993; Harris, 2003a; Nannini Meyers, 2000). The repeated thoughts of anxiousness, doubts and suspicions someone has about his or her partners potential infidelity and external relationships characterize cognitive jealousy (Theiss Solomon, 2006). It involves someone who is obsessed by mistaken beliefs, worries and suspicions about rivals to a valued romantic relationship. Cognitive jealousy implies the construction of elaborate cognitive scenarios that result in biases toward perceiving relational threats and misunderstanding of the partner’s behavior (Rydell Bringle, 2007). Examples of cognitive jealousy include a person always imagining a romantic partner as disloyal, interpreting the way their partner interact with the opposite sex as flirting, or comparing oneself incessantly with a potential romantic rival. Behavioral jealousy Behavioral jealousy was defined by Pfeiffer and Wong (1989) as the â€Å"detective/protective measures a person takes when relationship rivals (real or imaginary) are perceived† (p. 184). Jealous behaviors may be expressed in many ways however; the purpose to either protect the relationship or notice potential threats to the relationship is what they have in common. The goal of someone who expresses behavioral jealousy is to ensure that intimacy does not take place between ones partner and a third party. Examples of behavioral jealousy include being inquisitive, checking up on one’s partner, searching his or her belongings, mobile phones, making uncomplimentary statements about the rival, or trying to come in between the partner and rival when they are engaged in conversation. According to this definition, spying or surveillance of one’s partner would consist of a more severe form of behavioral jealousy. White (1981) viewed such behaviors as ways to manage emotions, especially as jealousy is more probable to occur for individuals who are in committed relat ionships than for individuals who are in an open relationships or singles (Pines Aronson, 1983; White Mullen, 1989). A study done by Theresa Hurton (2011), who looks at the relationship between social network site Facebook and how it impacts college romantic relationships, found that there is a positive correlation between checking Facebook daily and presence of jealousy in romantic relationships. Other scholars for example Muise et al (2009) conducted a study that reveals a significant association between time spent on Facebook and jealousy related feelings and behaviors experienced on Facebook. Nowadays Facebook is known to almost all people in the world, it is a new phenomenon and I think most people have a personal Facebook account, be it youngsters or adults. It has become one of the largest procrastinating tools’ for almost everyone. Despite the good sides that Facebook has, one example is that it provides the ease of communication, it does bring along some notorious effects, and one of them is that it may put romantic relationships at risk of breaking by inducing jealousy feelings in couples according to the literature.

Definition Essay - Defining Freedom -- Expository Definition Essays

Definition Essay – Defining Freedom Is it possible to define freedom? To define freedom is more than a difficult task, but perhaps easier than one might imagine if not overanalyzed. Given ample time to consider the task, however, a simple, sufficient definition can present itself: freedom is the ability to choose, for any creature living life in any place in any time. There is no greater truth to the statement, and no underlying meanings; freedom is simply the ability to choose. So one might ask, "If this ability to choose applies to all creatures in all places in all times, why can freedom only be defined in the context of the specific creature whose definition of freedom is concerned?" That is simple. Freedom is something that can only be experienced to some extent; there is no such thing as absolute freedom. However, each varying life form has differing boundaries to which this freedom can conform. If such a thing as absolute freedom were to exist, then those who possessed it could do absolutely anything imaginable. One could then wonder, if there is th...

Illegal Street Racing Essay -- essays research papers fc

One of the fastest growing sports in the world is racing. Racing in general can consist of many different types such as: Drag Racing, NASCAR, Indy, Motor Cross, Truck Rally. The topic of racing that I am chose was street racing. Street racing originated from drag racing on the quarter-mile strip. The concept of drag racing is when two racers in different cars would line up at a white line, and in the middle of the two cars would be a light post, called the Christmas tree for its red, yellow and green bulbs. The tree does what a stoplight does, except backwards, it starts from red, then to yellow, then to green. On the quarter-mile strip, when the light hits green, the two racers are supposed to try to go as fast as they can before the end of the quarter-mile, which would then set off a electronic board showing their electronic times (E.T.) and their speeds. As the sport of street racing began to boom around the early ‘90s, people couldn’t really afford to go to a legal track and race their cars, because of the price that it cost and the rules that they had. So there was a street track that was created on Terminal Island, called the Brotherhood Raceway. The Brotherhood Raceway or Brotherhood for short was basically a quarter-mile drag strip that was put down on a closed off street, where street racers could go and find out their quarter-mile times and speeds for the price of nothing. This was a quarter-mile drag strip to keep racers off of normal streets and highways. Around time of the mid-90s, the Brotherhood was then closed down, forcing street racers to take their racing to another legalized track, or to the streets and highways. People say that street racing is bad, illegal and dangerous to everyone. There is another side which thinks that street racing is ok, and safe. All street racers know that street racing is illegal and can be dangerous, but in their minds they will think they won’t hurt people around them but accidents do happen. When it comes to racing on streets, racers an open or deserted street and line two cars up, and basically race off of the line and see who stays ahead of the other person, this set-up is basically like racing on a drag strip, just without lights and tech and safety people around. There is a person that acts like the lighting tree, who stands in the middle, and is called the â€Å"flagger.† This person puts his/her arms up, ... ...he track. That is why my opinion stands that they should re-open the Brotherhood Raceway, so racers can go and be safe while doing what they do. Street racing is a dangerous sport, but it’s a life and love that people have and are not willing to give up. I believe that as long as racers do what they can to keep street racing, that it should be legal. It all racers do their part in trying to keep it safe and not dangerous, then I think the government or city or whoever, should give street racers respect and allow them a place to have fun and do what they do best.

Cloud computing Service Essay

The â€Å"cloud† refers to the Internet; it is usually hosted on more then one server in multiple locations, normally neither the public nor the businesses know where the information is located. Many consumers are turning to the cloud to store and retrieve their data from any computer in the world. They are using this service to store their software, conduct, documents, other personal and all business operations. Many different consumers are using cloud; but many are using cloud with out taking a look at the advantages and disadvantages that comes with using the cloud computing service. There are three types of service provider by cloud computing models. One is software as a service or SaaS, this service provides consumers with the ability to access user application or service that is located within the cloud. In this service consumer are responsible for update and maintaining the operating system and software. Some of the providers that offer SaaS is Google and Microsoft. The second service provider is Platform as a Service or Paas. Paas allows consumers to purchase access to the platform and solution stack, which includes system, programming language, database and web server. Consumers also, can build their own applications, which could run on the cloud service provider. Some of the providers are Google’s app engine and force.com. Lastly, there is the Infrastructure as a services or Iaas. Iaas provides basic storage and computing capabilities as services over the network. Consumers control and maintain the systems in term of the operating systems, applications, storage, and network connectivity, but consumers do not have any control over the cloud infrastructure. Some providers of the Iaas are, Amazon, GoGrid and 3 Tera. Another type of provider is deployment model of cloud computing, where consumer chooses a unique is based on their specific requirements. There are four primary cloud deployment model private cloud, community cloud, public cloud and hybrid cloud. Private cloud is operated only by one organization,  it can also be managed by the organization or third party and externally. Community clouds are shared by many organizations, and support a specific community that has similar interests and requirements. Public cloud is owned and operated by third party, were it is available for the public on a commercial basis. Lastly, hybrid cloud is two or more deployment like private, community and/or public; this gives the user the ability through their interface to allow data, and also applications to move them from one cloud to another. The advantage of using cloud-computing service is that it can be accessed from any part of the world as long as there is Internet connection. The cost is significantly lower to operating data processing service with compared to the older meth of establishing and maintaining software and hardware on an internal system. This will remove the need for operating costs that accompanying with purchasing or by leasing such software and hardware. Depending on the cloud provider used, storing information to the cloud is almost gives unlimited storage capacity, that will give the public and business no more worries about not having enough storage space. Since data is stored in the cloud, backing up and restoring is much easier then storing on a physical device. Most cloud computing service providers usually are skilled enough to handle recovery of information. The disadvantage of cloud computing service is the technical issues, security issues, and that the information is easily prone to attacks. Even though we can access the information and data on the cloud from anywhere in the world, there are times that the system can have some serious dysfunction. The consumers should be aware that technology is always prone to outages and technical issues. Even the best cloud providers will run into these kind of problems, in spitefulness of keeping high standards of maintenance. Consumers will need a reliable internet connection server at all times, but will be consistently be stuck with networking and connectivity problems. The security to the cloud is another major issues that the consumer don’t look at when submitting all their personal and companies sensitive information that it is being submitted to a third party cloud computing service provider, which could put your information in great risk. Consumer should make absolutely sure that the provider they choose is reliable and will keep their information totally secure. The cloud provider is prone to attack by hack attack and other threats. Storing your information in the cloud could make your personal and business unprotected. Although nothing on the Internet is completely secure, and there is always the lurking possibility of stealth of sensitive data. Any user of any Internet storing should carefully look at the advantage and disadvantage of cloud computing service before submitting any type of information. Also consumers should be aware of the potential risks and problems that is accompany with the cloud. WORKS CITED Jr, R. C. (2010, August 24).

Our hearts fell to the ground Essay

Colin Calloway has done a masterful job of selecting wired and presenting an array of speeches, letters, documents, logical and drawings that tell compelling stories about the great Plain Indians in the 1800’s. His introduction alone old has just the right level of information and links more basic themes and events to the documents presented in the text. In short, a model of how an introduction should be done.Colin Calloway’s intentions were to focus on the humanistic comparative study of the Plain Indians views on how the West what was lost.Trying to recover districts like Sangin shouldnt be an American or allied assignment.Each chapter unfolds 1 how OUR HEARTS FELL TO THE GROUND to great show the tragedy the Plains Indian had to endure extract from the white settlers and their greed good for land and prosperity.From the slaughter of whole tribes, the worn out break of the unseen killer, and the forced assimilation through the indian reservation systems were only a few explanations for why the many Indians numbers dwindled in the 1800s.
