Explanation and Chart of Ser Versus Estar

There are few things more confusing for beginning Spanish students than learning the differences between ser and estar. After all, they both mean to be in English. Differences Between Ser and Estar One way to think of the differences between ser and estar  is to think of ser as the passive verb and estar as the active one. (The terms arent being used in a grammatical sense here.) Ser tells you what something is, the nature of its being, while estar refers more to what something does. You might use soy (the first-person present of ser, meaning I am) to explain who or what you are, but youd use estoy (the first-person present of estar) to tell what you are being or doing. For example, you might say, Estoy enfermo for I am sick. That would indicate that you are sick at the moment. But it doesnt tell anyone what you are. Now if you were to say, Soy enfermo, that would have a different meaning entirely. That would refer to who you are, to the nature of your being. We might translate that as I am a sick person or I am sickly. Note similar differences in these examples: Estoy cansado. (I am tired.) Soy cansado. (I am a tired person. My nature is to be tired)Estoy feliz. (Im happy now.) Soy feliz. (I am happy by nature. I am a happy person.)Està ¡ callada. (Shes being quiet.) Es callada. (Shes introverted. Shes naturally a quiet person.)No estoy lista. (Im not ready.) No soy lista. (Im not a quick thinker.) Another Approach to Ser vs. Estar Another way of thinking about the two verbs is to think of ser as being roughly equivalent to equals. Another approach is that estar often refers to a temporary condition, while ser frequently refers to a permanent condition. But there are exceptions. Among the major exceptions to the above way of thinking is that ser is used in expressions of time, such as Son las dos de la tarde for Its 2 p.m. Also, we use estar to indicate someone has died—quite a permanent condition: Està ¡ muerto, he is dead. Along that line, estar is used to indicate location. Estoy en casa. (I am at home.) But, soy de Mà ©xico. (I am from Mexico.) Ser, however, is used for the location of events: La boda es en Nuevo Hampshire. (The wedding is in New Hampshire.) There are also a few idiomatic expressions that simply need to be learned: La manzana es verde. (The apple is green.) La manzana està ¡ verde. (The apple is unripe.) Està ¡ muy bien la comida. (The meal tastes very good). Note that sometimes estar is often modified by an adverb such as bien rather than an adjective: Estoy bien. (Im fine.) Although rare, there are a few situations where you can use either ser or estar. A married man  describing his marital status could say either Soy casado or Estoy casado. He might be more likely to use soy because he considers being married as part of his identity, although he might use estoy to indicate that he had been married recently. Present Conjugation of Ser and Estar Both ser and estar are irregularly conjugated. Heres a chart of the indicative present tense: Pronombre Ser Estar Yo soy estoy Tà º eres està ¡s Él, ella, usted es està ¡ Nosotros somos estamos Vosotros sois està ¡is Ellos, ellas, ustedes son està ¡n Sample Sentences Susana es atenta y con buena comunicacià ³n. (Susana is thoughtful with good communication skills. Ser is used with a personal quality.)Susana està ¡ atenta a la situacià ³n de su amiga. (Susana is attentive to her friends situation. Estar is being used to characterize behavior.)Roberto es nervioso como mi hermano. (Roberto is as nervous of a person as my brother is. Ser is used here for describing what kind of person someone is.)Roberto està ¡ tan nervioso como mi hermano. (Robert is as nervous as my brother is now. Estar is used for an emotional state that is independent of personal qualities.) Quick Takeaways Ser and estar are the two verbs most frequently used as the equivalent of the English to be.Ser typically is used in describing the nature of someone or something.Estar typically is used in referring to a state of being that isnt necessarily innate.

Analysis Of Jamieson s The Double Bind And A Bitch

Jamieson (1995) Beyond the Double Bind, Double Bind Number Four: Femininity/Competence The sixth chapter in Jamieson’s (1995) book Beyond the Double Bind works strictly with the bind of femininity and competence. This is the bind where women have to balance a fine line between feminine and masculine without tipping the scale. If a candidate shows too much femininity, she risks losing brains, and authority. On the other hand, if a candidate is not feminine enough, she becomes too masculine, strong, shrew, and a bitch. According to Jamieson, gender stereotypes and gendered language are factors reinforcing the bind. The more women begin taking posts traditionally held by males, the more people view them as competent leaders. By taking leadership positions, women being to dismantling the standards of the femininity/competence bind. Many double binds exist for female candidates and the femininity/competence bind is more apparent in their representation in the news media.

The impact and benefits of internet on marketing mix free essay sample

Few things have dramatically and immediately impacted our lives and the way many businesses operate more than the development of the Internet. The ways that some marketing activities are performed have changed as businesses have turned to e-commerce. The Internet provides opportunities for an organization to enhance its business in a cost-effective and practical manner. That is, the Internet can be used to conduct marketing research, reach new markets, serve customers better, distribute products faster, solve customer problems, and communicate more efficiently with business partners. The benefit of Internet marketing includes the improved flow of information, new products and customer services, improved availability, improved market transparency. To design and implement a successful e-marketing program, a number of theories, applications, and technologies must be carefully analyzed and understood. In this article the investigator is going to considerer the best Internet marketing ways for the success of business. The main objective of this article is nothing but understanding the impact of Internet on different marketing areas such as product development and service provision, promotion, pricing and distribution channels. We will write a custom essay sample on The impact and benefits of internet on marketing mix or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In the article it is demonstrated that when manufacturers connect directly with consumers and shorten the distribution channels, inefficiencies can be eliminated, product delivery time can be decreased, and manufacturers can build closer relationship with consumers. Consumers use the Internet to reduce costs, find products otherwise unavailable, or increase their shopping convenience. Online consumers expect easy,understandable, and secure ordering and payment systems. Customers want assurance that orders will be filled immediately. E-commerce creates value for customers in many ways. Customers are treated as a market of one. They can access a greater variety of products, often at lower prices. The study suggests that businesses should pay special attention to the impacts of the Internet and its uses in marketing to be successful and profitable. Key words: Internet marketing, E-commerce, E-marketing, promotion. Introduction: One of the hottest topics in business and the media today is electronic commerce. The Internet and its graphical interface, the World Wide Web (WWW), are key components of an electronic commerce initiative that is playing an ever-increasing role in the future of the global marketplace. (Honeycutt et al. , 1998) Electronic commerce has been defined as â€Å"any form of business transaction in which the parties interact electronically rather than by physical contact†. (Aldin and Stahre, 2003) Electronic commerce and its application have become everyday discussions and various articles and literature have been written in this regard. Access to the domain of electronic world has become priorities of most of the big and small public and private organizations and as such, managers have encountered new challenges in this field. (Elahi, Sh. and Hassanzadeh, 2009) Using the internet and related technologies to complete significant marketing activities is known as e-marketing or electronic marketing. The ways that some marketing activities are performed have changed as businesses have turned to e-commerce. However, the basic principles of marketing still apply. E-commerce businesses must understand marketing basics and use them effectively in order to be successful and profitable. (Kleindle and Burrow, 2005) The ubiquitous nature of the Internet and its wide global access has made it an extremely effective mode of communication between businesses and customers. The growth of Internet technology has enormous potential as it reduces the costs of product and service delivery and extends geographical boundaries in bringing buyers and sellers together. (Teo, 2005) Additionally, international communications generated by the Internet are likely to result in greater levels of satisfaction between companies and customers. (Kleindle and Burrow, 2005) The Internet provides opportunities for an organization to enhance its business in a cost-effective and practical manner. Chen, S. (2005) That is, the Internet can be used to conduct marketing research, reach new markets, serve customers better, distribute products faster, solve customer problems, and communicate more efficiently with business partners. Turban and King, (2003) Quality benefits of e-commerce use could include the improved flow of information, new products and customer services, improved availability, improved market transparency and reduced errors in information processing. (Lewis and Cockrill, 2002) The Internet is also a useful tool for Correspondinggathering intelligence on customers, competitors, and potential markets, as well as communicating information about companies and/or products. (Kleindle and Burrow, 2005) The Importance of the E-Business Customers: Customers are the lifeblood of a business. They decide whether to purchase a companys products or the products of a competitor. They may be persuaded to try a product once. If satisfied, they are more likely to purchase from the company again. They may encourage friends and family to buy as well. Companies with satisfied customers are likely to be successful. Those that are unable to satisfy customers will soon fail. One of the most important tasks of marketing is to identify prospective customers for a company. The activities needed to attract customers include marketing research and promotion that gets the attention and interest of new prospects. Also important are some types of incentive to encourage customers to make their first purchase and follow-up activities that ensure customer satisfaction. Any concerns the customer has about the product must be identified and resolved. Companies that have clearly identified their potential customers can concentrate their marketing resources on those prospects. (Kleindle and Burrow, 2005) Customers Characteristics: There are certain types of consumers who are likely to be internet customers. They are people who are comfortable with technology and innovation. An innovation is a new and unique product, process, or idea. Most people are reluctant to try something that is totally new. However, a small percentage of the population (about two percent) is considered to be innovators. Innovators want to be the first to try new products. When businesses began selling products online, innovators were their first customers. However, if the business expects consumers to use the internet to purchase its products, marketing efforts should be directed toward innovators and early adopters. (Kleindle and Burrow, 2005) Various profiles of Internet shoppers suggest their median age to be in the range 30-35; mostly single (59%) and having a college degree (57%). (Kiang et al. , 2000) Every business has access to thousands and sometimes hundreds of thousands of consumers. A business needs to develop an effective method of identifying those consumers who are most likely to purchase. It should concentrate its marketing efforts on attracting and satisfying those customers. (Kleindle and Burrow, 2005) Impacts of Internet on Marketing Mix: Although there has been a trend toward the new marketing approaches used in e-commerce, this is not to say that traditional marketing concepts cannot be applied. The conventional four Ps of marketing, product, price, promotion and place, are as relevant to online businesses as offline ones. However, e-commerce brings new issues that must be considered and may require a rethinking of the existing marketing mix. E-commerce technologies offer new product/service and new placing options as well as new pricing strategies. However, one of the biggest effects has been on promotion. Chen, S. (2005) Product: The primary reason people purchase from a business is directly related to its products. (Kleindle and Burrow, 2005) Product characteristics play a major role in the successful marketing of a product on the Internet. (Kiang et al. , 2000) The form of some products is modified with the use of the internet. Electronic books, e-tickets, digital photographs, and online bill paying are examples of changes in the form of traditional products. Some consumers find the new forms more satisfying while others prefer the products in their original forms. (Kleindle and Burrow, 2005) There is a broad range of products marketed on the Internet that range from consumable goods to durable goods. Services marketed on the Internet also range from online newspapers tobusiness-wide consultation. (Kiang et al. , 2000) Digital Products: Digital technology has allowed businesses to develop a new generation of products. Companies develop and market a variety of digital products. Those products are designed for both business and consumer markets. Two categories of digital products are content and technology. Digital content consists of information in digital format including video, audio, text, and graphics. The content is converted to business and consumer products such as newspapers, magazines, online games, photos, graphics, and videos. Digital technology is the equipment used by businesses and consumers to develop, store, distribute, and use digital content. The technology ranges from digital video and audio equipment to cellular telephones, personal digital assistants (PDAs), and computer software. (Kleindle and Burrow, 2005) Digital Services: Just as services are a major offering of traditional businesses, digital services are equally important in e-commerce. Digital services are developed and marketed to both businesses and final consumers. Categories of digital services are business-support services, consumer services, and digital communications services. Business-support services are the activities that support businesses in developing and delivering digital products and services. Business-support services include web design, web site hosting and management services, and digital content production (such as video, audio, and multimedia development). Consumer services are the activities that support consumer access to and use of internet resources and digital information. Common consumer services are internet service providers (ISPs), information portals, and media distributors such as digital television and radio stations. Digital communications services provide management of the technology and procedures that support business and consumer virtual communications. (Kleindle and Burrow, 2005) Developing Products for E-Commerce: The development of personal computers, the internet, and digital technology has generated opportunities for new products. Many existing products can be marketed more widely to prospective customers. Additionally, many new-to-the-world products have been developed as a result of recent technologies. The internet allows companies to mass customize a wide range of products. Examples of products that are being custom manufactured include eyewear, clothing, golf clubs, bicycles, fishing rods, and CDs. Smaller businesses use customization to gain competitive advantage. Larger businesses use customization to lower costs. Customers receive and pay for only the features they need. (Kleindle and Burrow, 2005) Nike offers online shoppers the opportunity to customize a running shoe, personalizing such features as the outsole, the amount of cushioning, and the width. The personalized shoe costs about $10 more than buying a comparable—but not custom—shoe off the shelves of the local Nile retailer. Shoppers are also able to personalize mens and womens dress pants and mens dress shirts at Landsend. com. Heiligtag and Xu, (2006). Price: Price is another stimulus that for most consumers has a high impact on the online purchase. Fagerstron and Ghinea, (2011) Marketing pricing is still what it was, the price that customers are willing to pay, based on considerations such as the company, brand, reputation and product. The difference that e-commerce makes is that pricing and competitor information is faster and more transparent, meaning that market forces also tend to act faster and perhaps more efficiently. There is thus a tendency for prices to converge at lower levels. Harris and Dennis, (2002) Theory development in e-pricing has largely focused on price competition and price sensitivity online relative to offline. The widespread belief that search costs are lower online has sparked much interest among researchers in finding ways of lowering online price consciousness and creating differentiation. Mahajan and Venkatesh, (2000) As Peterson et al. stated Internet-related marketing can result in extreme price competition when products or services are incapable of significant differentiation. (Kiang et al. , 2000) Price-based Strategies: Businesses that focus on gaining market share by selling at low prices or at prices that fluctuate with market demand are using a pricing strategy. Greater efficiency allows some businesses to sell at lower prices because of lower overall costs. Cost savings result when a business does not need brick-and-mortar assets, when fewer employees are needed, and when technology is used to reach and serve customers. Customers save money, time, and energy when they can use the internet to aid in the search and purchase process. Pricing decisions are particularly critical for the e-business as there is a customer perception that prices should be lower online than otherwise. Harris and Dennis, (2002) The internet increases customer negotiation power. Customers can easily find and compare prices among suppliers. Customers can use software-based search systems called intelligent shopping agents that return product and price information. My Simon uses intelligent shopping agents to provide price and product comparisons. Intelligent shopping agents are useful for comparing products that have similar features and multiple vendors. (Kleindle and Burrow, 2005) Promotion: Businesses use a promotional mix to reach their objectives. A promotional mix includes advertising, personal selling, sales promotions, and hypermedia. Today, most e-commerce promotional campaigns require a combination of traditional methods and hypermedia. Reliance on hypermedia alone may not allow a company to reach its goals. Each element of the promotional mix has strengths for reaching specific communication goals. An integrated marketing-communication strategy brings together multiple media to reach desired goals. Hypermedia are strongest in the areas of creating interest and desire, but can also be used to facilitate action such as opting into a list or making a purchase. Hypermedia enhances the visibility of firms and creates new business opportunities. Hypermedia also save money and time and allow businesses to reach new customers. (Kleindle and Burrow, 2005) Online Advertising: Promotional placement in a medium is known as advertising. The internet is the fastest-growing advertising medium. It took only five years to reach 50 million users. To reach this level of growth, radio took 38 years, television took 13 years, and cable took 10 years. (Kleindle and Burrow, 2005) In traditional marketing, advertising was impersonal, one-way mass communication, paid for by sponsors. Telemarketing and direct mail were attempts to personalize advertisement in order to make it more effective. These direct marketing approaches worked fairly well but were expensive and slow and seldom truly one-to-one interactive. The Internet introduces the concept of interactive marketing, which has enabled advertisers to interact directly with customers. Turban, E. , King, D. (2003) It allows information to be accessed without geographical location constraints and offers the possibility of delivering messages enhanced by color, sound and animation effects, as well as two-way interactions. The interactive nature of the internet facilitated customer support and market activities to a greater degree than traditional media. Kurtz and Boone, (2006) In interactive marketing, a consumer can click on an ad in order to obtain more information or send an e-mail to ask a question. Beside the two-way communication and e-mail capabilities provided by Internet, vendors also can target specific groups and individuals on which they want to spend their advertising dollars. Double Click is the premier company in this area. Finally, the Internet enables truly one-to-one advertising. Banner Ads: A banner is a graphic display on a web page that is used for advertising. Banner advertising is the most commonly used form of advertising on the Internet. Fagerstron and Ghinea, (2011) Banner ads are typically small strip messages placed in high-visibility areas of frequently visited Web sites. Heiligtag, J. , Xu, J. (2006) Banner ads act like placement ads in print media. To catch a viewers eye, banner ads are now using animation, java programming, and multimedia. Banner ads are useful in creating awareness of products and in communicating information about them. (Kleindle and Burrow, 2005) Place Distribution: Distribution is an important part of any marketing transaction. It usually involves several businesses. It may take many days or weeks of numerous activities. Distribution is expensive. It can account for 50 percent or more of a products final price. Distribution activities do not disappear when a business moves to an e-commerce strategy. (Kleindle and Burrow, 2005) Distribution is a vital decision area for the e-business for three reasons. First, relatively small local companies can widen their market and even export. Second, many e-businesses aim to gain competitive advantage by using e-systems to de-layer the distribution chain. For example, Dell supplies customers directly, rather than through distributors, wholesalers or retailers. Third, distribution is an area where some e-businesses have been severally criticized for failing to deliver customer service. Harris and Dennis, (2002) E-Commerce Distribution: Marketing channel intermediaries were in the early days of electronic commerce considered to add only cost and limited value, where upstream participants pursuing electronic commerce strategies threatened such intermediaries by attempting to bypass them. Aldin, Stahre, (2003) Using the Internet, manufacturers can sell directly to customers and provide customer support online. In this sense, the traditional intermediaries are eliminated, or disintermediated. Disintermediation refers to the removal of organizations or business process layers responsible for certain intermediary steps in a given supply chain. In some countries, such as Japan, one may find inefficient distribution networks with as many as 10 layers of intermediaries. These extra layers can add as much as a 500 percent markup to the manufacturers’ prices. Turban, E. , King, D. (2003) The top categories of items sold by larger firms on the Internet include computer hardware and software, airline and hotel reservations, financial services, collectibles, books, CDs and gift items. The most successful and profit-making large sites include Dell, Expedia, E*TRADE, e-Bay, Yahoo! and Amazon. However not all goods and services are suited to direct sale over the Internet. In many sectors the Web represents another channel or source of information supporting sales by other means. Few high value items such as cars are traded over the Internet, but many sites provide information of interest to car purchasers. Similarly there are many sites for real estate, but few direct purchasers of homes over the Internet. Drew, S. (2003) Jupiter Communications studies show that the largest industries involved in Internet shopping in the USA were, in decreasing order: travel, PC hardware, groceries, gifts/flowers, books, PC software, tickets, music and clothing. Elliot, S. , Fowell, S. (2000) Dell Computer has established itself as one of the world’s most successful e-tailors by profitably selling its computers directly to millions of consumers over the Internet. Turban, E. , King, D. (2003) Comparing Traditional and E-Commerce Distribution: Whereas past channel research has focused primarily on order fulfillment (i. e. , physical distribution) through the retail channel, it is now necessary to distinguish between online and offline channels and between the channels’ role for order procurement and order fulfillment. For products distributed through the Internet, the channel for order fulfillment may be short as with direct delivery. But the channel for order procurement is often long with intermediaries such as Internet service providers, search engines and infobots. Mahajan and Venkatesh, R. (2000) When consumers become regular internet purchasers, their perspectives regarding distribution often change. Consumers use the internet to reduce costs, find products otherwise unavailable, or increase their shopping convenience. Internet customers typically expect service 24 hours a day, seven days a week. Quick access to customer-support information regarding products, prices, and shipping options is expected. Because the speed of the internet is almost immediate, customers tend to expect the speed of distribution to be fast as well. Customers may be unwilling to wait days or weeks for product delivery. Online consumers expect easy, understandable, and secure ordering and payment systems. Customers want assurance that orders will be filled immediately. They want an easy, low-cost way to return a purchase if it does not meet their needs. (Kleindle and Burrow, 2005) Value in an Electronic Marketplace: Consumers make decisions about value based on how they will use available resources to satisfy their needs and wants. At its most basic, value is the benefits that customers receive given the costs (in money, time, and energy). (Kleindle and Burrow, 2005) Value seems to have an effect on a consumer’s consumption behavior, pricing, profit making and other strategic decisions of the firm. It is used to gain competitive advantage and to create loyalty, satisfaction and repurchase behavior. Therefore, value is a complex concept, which is greatly affected by individual and contextual aspects. Value is an important means of gaining competitive advantage. Thus, it is significant for managers to understand what value is, how it is created and how it could be added. Reijonen, H. , Laukkanen, t. (2010) E-commerce creates value for customers in many ways. Customers are treated as a market of one. Businesses create value by providing quality goods and services at acceptable prices. Service businesses are enhancing how they deliver their service. Customers can access a greater variety of products, often at lower prices. The most important value for many online shoppers is convenience. One study found that consumers saved almost 64 hours per year by shopping online. (Kleindle and Burrow, 2005) The e-business value for the customer consists of four variables: service, price, and quality and fulfillment time. Chen, S. (2005) Satisfaction: The internet provides many opportunities for companies to increase economic utility and, therefore, customer satisfaction. The most obvious forms of improved utility are time and place. Information can be accessed and products can be purchased any time of the day or night. Purchasing can be completed from the consumers home. Amazon. com is scoring satisfaction levels never before seen in a service industry. Amazon. com is applying its value-creation process used with books to many other products. Amazon. com e-commerce applications set value levels so high that customer expectations are increasing not only for Amazon. com but for all businesses. The main technologies that e-commerce businesses use to add value are the internet and databases. The internet allows access to e-commerce communication platforms. Databases allow products to be searched and viewed, questions to be answered, and products to be ordered, all in a fast and convenient timeframe. At one time, online-only companies were the only businesses using these technologies. Today, traditional businesses are adding e-commerce strategies to their marketing mixes. When e-commerce is combined with popular brand names and high levels of service, traditional businesses achieve competitive advantages. (Kleindle and Burrow, 2005) Conclusion: This paper describes the ways that some marketing activities are performed as businesses have turned to e-commerce. Findings show that the growth of Internet technology has enormous potential for businesses. There are certain types of consumers who are likely to be internet customers. They are people who are comfortable with technology and innovation. If the business expects consumers to use the internet to purchase its products, marketing efforts should be directed toward innovators and early adopters. Internet brings new issues that must be considered and may require a rethinking of the existing marketing mix. The internet allows companies to mass customize a wide range of products. Internet makes pricing and competitor information faster and more transparent, meaning that market forces also tend to act faster and perhaps more efficiently.

Lone Wolf free essay sample

Evaluate a significant experience, achievement, risk you have taken, or ethical dilemma you have faced and its impact on you. My mother—a single parent—works as a civil servant of Bhutan: due to her occupational hazards, I was entitled to attend boarding school and travel alone at a young age. Ever since I started to attend boarding school—in the sixth grade I have been travelling alone from Bhutan to Calcutta to Chennai. Normally, a parent would not succumb to such an act, but ever since I could so much as think, I knew I was not a normal child. I stopped giving in to horror movies once I realized they were fake, addendum: the fake 100 Ngultrum bills my mother would hide under my pillow whenever I lost a tooth. I could understand most of the complex and foul languages used in conversations unlike my other classmates—maybe it was the outcome of the vast array of books that have kept me company in my lonely flights to, and fro, Bhutan and India. We will write a custom essay sample on Lone Wolf or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page I was more mature than the others my age. School had just ended and I was on my way back to Bhutan. From Chennai, I had to stop by Calcutta and take the first plane to Bhutan in the morning, which was around twelve hours away. Normally, the airport would allow transit passengers waiting long flights to take shelter indoors, but on this particular day, due to certain circumstances—to this day I still don’t understand—I was told to wait outside. You would normally think it being cruel to have an innocent thirteen year-old boy standing out†¦ but it is India. I was anxious, the battery on my phone died due to excessive gaming to pass the long waiting hours in the airport, I could not call anyone. This was the first time this had happened to me and I felt constricted. I checked my wallet and noticed I had a few thousand rupees, which equaled to less than $75 at the time. I sat down on my bags, and thought of the possibilities that might have me survive the night. I asked and begged the guards to let me in, I showed them my tickets and my passport, yet they refused and told me to wait until the morning. This has never happened before. Had I grown or looked older? I got frustrated and so I asked one of the—with the little Hindi I know—guards for a cheap hotel anywhere nearby. He introduced me to this shabby taxi driver with crooked brown teeth, ragged clothes and grey hair, almost balled. He took me to a hotel, ten minutes drive away from the airport and charged me 500 rupees. I knew I was being ripped off, probably because of my age, but I did not want to offend them in anyway as I had reserved them to pick me up the next day for the same price. The hotel was in the shadiest part of town, pitch black with drunks walking around swearing abruptly in Hindi. I grabbed a hold of my items, checked into the hotel (which was 1200 rupees for the night) and locked myself in. The fan above my head creaked boisterously, shrouding the unceasing barks of dogs and the unending noise of drunken men enjoying their evening debauchery. The lemon yellow paint was peeling off the wet walls and the fan looked like it was going to drop. I lay on my bed anxious and wondering how I got myself into this sketchy situation. I wanted to go home. The next morning, the taxi driver had never left the area, as he seemed to have just slept in his car. He carried my luggage and placed them into the trunk and I jumped in on the front seat, as there seemed to be a drunken man sleeping on the back. The driver sat in the front seat, trying to converse with me in Hindi despite knowing that I know very little of the language as he drove me to the airport. As I left for the airport and headed home, along with a sense of relief, I also felt proud of myself. These isolated experiences show you that in the end you have to depend on yourself and how important it is to have a cool head and your wits about you. My sense of independence may not have been entirely derived from this stand-alone experience but it is sharply etched in my memory and as an effect has made me a braver and stronger person. As an unintended consequence, I had to take a big risk and in the end I believe I handled it very well. Independence means making strong and alert decisions even in the most harrowing of times.

The relative importance of imperialism, the arms race and the failure of diplomacy in causing the First World War Essays

The relative importance of imperialism, the arms race and the failure of diplomacy in causing the First World War Essays The relative importance of imperialism, the arms race and the failure of diplomacy in causing the First World War Paper The relative importance of imperialism, the arms race and the failure of diplomacy in causing the First World War Paper Essay Topic: World War I Historians are still today debating on what actually caused World War One. This is because the actual origin was a combination of many different factors. Short-term as well as long-term causes influenced the outfall of events, however some are more important than others. What is mainly agreed on1 is that Germany was the nation most to blame, however most of the more influential nations of Europe were somehow involved in the conflict. England, France, Russia, and Austria-Hungary didnt stumble into the war like Germany, but they all played an important role. Many historians have used the phrase stumbled into war to describe how Germany inevitably ended up in a total war against her neighboring countries. Unlike previous conflicts in history, more than two or three nations were involved, which is mainly due to the many alliances made in the years before. What makes it even more difficult to determine the origin of the war is that several non-human factors, like nationalism and imperialism, had key roles in developing the events that took place. The politicians and military leaders of the European nations were influenced by these ideas and therefore directed their nations almost inevitably into a major crisis, as it came out. This leads to the human factors of the war, like the arms race and the failure of diplomacy taking place during the beginning of the 20th century. Therefore I must stress that it was the combination of all these factors that eventually made this cataclysmic total war spread throughout Europe. The July Crisis as it later came known was the drop that made the glass flow over, but any other similar event could have had the same outcome. The European powers were so tense and aggressive, and some even thought about revenge from previous wars2, or simply to expand their territory. In this essay I will evaluate the relative importance of imperialism, the arms race, and the failure of diplomacy as origins for World War One. Appropriate events and theories have been taken as examples for each of these three categories, to compare the significance of each. 3 Body Imperialism During the industrialization of the 19th century, all great European powers consumed vast amounts of natural resources to supply the many factories emerging in the industries. However since these natural resources are limited in abundance within Europe, these overseas empires, as for example Britain, France, Spain, and later Germany, sought beyond towards other continents in search for colonies. The colonies then provided their mother country with the natural resources needed in the rapidly spreading industrialization. In Germany this development was known as Weltpolitik4 and later became the term used to describe the overseas expansionism that European leaders sought to achieve. These ideas became stronger in the 20th century and drove the European powers into several conflicts. Several times between 1898 and 1914 the economic rivalry in Africa between France and Great Britain, and between Germany on one side and France and Great Britain on the other, almost precipitated a European war. 5 Most significant were the conflicts in the Balkans between Russia, Austria-Hungary and the Balkan nations. Imperialist Austria-Hungary sought to influence the Balkan nations and annexed Bosnia-Herzegovina in 1908 after thirty years of remote administration. But nationalistic movements in the Balkans led to two Balkan Wars in 1912 and 1913. The first war was an uprising against Austria-Hungary, which was crushed. The Second Balkan War was fought between Bulgaria and most other Balkan nations. Although Bulgaria was overwhelmed and the war ended rapidly, no single nation was satisfied with the post war negotiations creating more tension. As an origin of World War One this is significant because the tension in the Balkans became crucial in the summer of 1914. When Crown Prince Ferdinand (heir to the Austria-Hungarian throne) was assassinated in Sarajevo, Austria-Hungary was forced into war with Serbia. This clashed with Russian interests, and when Germany declared full support to Austria-Hungary6, it left Russia in a vulnerable situation, eventually having to mobilize herself. Therefore the imperialist desires of Austria-Hungary led the nation into serious conflicts in the Balkans, and eventually created the most important short-term cause for World War One. Therefore imperialism did have influence as an origin of war, as it became the mentality of the leaders of the European powers, and in this case forced Austria-Hungary and Russia into protecting national interests. Although imperialism itself was a long-term cause of war, it played a significant role in creating the short-term causes. It is agreed among historians that the importance of imperialism rested in the fact that it left the politicians fewer options to deal with regarding diplomacy. This conflict later became known as the July Crisis. 7 Arms Race Not only colonies measured the strength and prestige of European empires. The emerging industries of the 19th centuries provided the nations with significant armies and weapons of destruction. As imperialism became a significant part of the political agendas in the beginning of the 20th century, the great nations attempted to show their strength through developing great armies. With Germany becoming a significant power after 1872, the European balance of power was tipped off. This triggered an arms race between the leading nations, France, England, Germany, Russia, and Austria-Hungary. With vast amounts of industries being brought in from colonies and produced within Europe, the countries were able to produce great amounts of war material. Especially the continental armies of Germany and Russia were competing in numbers. As Russia was becoming an industrial nation, it wouldnt take many years for her to surpass match the might of the German army (if not the superb efficiency and leadership). Therefore the German military leaders, under pressure from the Triple Entente8, had to calculate the risks of war. The conclusion came to be that if a war was to come between Germany and Russia, then rather sooner than later. 9 Germanys Weltpolitik aimed to turn Germany into an overseas empire. In order to achieve this Germany would need a considerable navy to compete with Britain. Combined with the economic pride of the German people, the German government embarked on the task to build a respectable navy. This would both help Germany defend overseas interests in for example Africa, and also as a defense against the mighty British navy in the North Sea. Hence a naval competition emerged between Britain and Germany. Admiral Fisher of the British Navy calculated in 1907 that it would take Germany several years to match the British fleet, especially considering the newly designed Dreadnought battleships. Truly, in 1914 Germany only had thirteen Dreadnoughts versus Britains twenty10. The consequence of this large-scale arms race was international anarchy in Europe. Calculating war risks and making alliances were becoming constantly discussed subjects in European governments. When five great nations all strive to create large armies, it is obvious that war will become inevitable sooner or later. In 1914 the short-term cause happened to be the July Crisis, but it could in theory have been any other critical occasion. Therefore it is important to observe the military tension developing between the nations, and the significance of diplomacy to balance the power. The diplomatic failures in the years leading to the Great War are therefore to be considered as well. Failure of Diplomacy As Germany was quickly becoming a very powerful force in the center of Europe, the surrounding nations were becoming doubtful of their national security. Therefore several military alliances were made between nations to contain rivals. The Triple Alliance of 1882 between Germany, Austria-Hungary, and Italy was still in effect at the beginning of the 20th century. To counter-balance this, France and Russia made agreements in 1892-94 to support each other in the event of war. Strategically placed on both sides of Germany, Russia and France posed a threat to the German empire. In 1904 Britain and France make a military understanding known as the Entente Cordiale. This was another measure to protect overseas interests as well as a balance against Germany. To complete the containment of Germany, Russia and Britain make a similar agreement in 1907. Obviously this posed a serious threat to Germany, as she was not only threatened on two fronts, but also by the greatest navy in the world. This only encouraged Germany to continue the rapid production of military equipment, and to further enlarge the German Navy as well. Diplomacy also played an important role in the July Crisis of 1907. When Prince Ferdinand was assassinated in 1914, Germany immediately promised Austria-Hungary unconditional support. This furthermore threatened Russia, who would risk war with two nations on her front in a worse case scenario. Yet the conflict could have been settled with diplomacy at this point, but it failed terribly. In July 23 1914 Austria issued an ultimatum to Serbia, proposing to enter the nation with troops, to help investigate the assassination. Unfortunately Serbia was only granted 48 hours to reply to this proposal, which didnt seem in any way realistic. Having Austrian troops within Serbia would not end the domination that already existed, on the other hand it almost seemed like an invasion. So Serbia did not accept the proposal. This seems to be the main diplomatic failure of the July Crisis. It was for one thing a very short notice the Serbs were allowed to work with, another thing is that it was unacceptable. Serbia was forced to pick sides between Russia, a nation with strong interests in the Balkans, and the Austria-Hungary, with clashing ambitions. It therefore seems like Austria-Hungary almost provoked the war with Serbia, leading to war with Russia. Surely the Austrian diplomats did not strive to avoid it. 11 Now Germany didnt seem to want to solve the crisis, instead she mobilized her army, and thereby forced Russia into full-scale mobilization12. Germany knew that a war on two fronts was inevitable, and therefore created the Schlieffen Plan to counter it. This also shows how Germany was calculating risks, and had been doing so for years. It is therefore applicable to consider the statement that Germany stumbled into war. She did not try to avoid it by negotiating, but did the exact opposite, provoked it. Therefore the failure of diplomacy was a significant factor towards the cataclysmic event that was triggered in July 1914. However, the aggressive sentiments created by the arms race combined with expansionist ideas, left the politicians with very few possibilities in the time of crisis. Conclusion The three origins of war evaluated in this essay were not significantly different in importance. It was the combination of the several factors that pushed the different nations into war. The arms race created strong military tension; the many alliances pushed off the balance of power and further accelerated the arms race, and the imperialist ideas influenced the decision making of the military leaders in critical situations. The situation created in Europe was not to last for very long, and maybe was the only way to achieve a more stable balance between the great nations. One can question the fact if war could have been avoided, but it is very hard to determine as so many different factors influenced the course of events. Many historians actually believe that war is the ultimate test of mankind to lead the evolution of strong nations and end the reign of weaker ones. In some ways it makes sense considering that Austro-Hungarian Empire consequently came to an end, and many other changes could be seen on the European map after the Great War. Germany was forced down to her knees and lost much territory to France and Russia, however she managed to regain her strength in such a way that she eventually invaded most of Europe thirty years later. 13 Therefore the relative importance of the three evaluated origins is that they all combined and pushed the European powers into the cataclysmic war that defined the end of the Old World. 1

A review on delay-minimized routing protocol in mobile cognitive ad hoc networks

A review on delay-minimized routing protocol in mobile cognitive ad hoc networks Mobile Cognitive Ad Hoc Networks is one of the cognitive radio networks which is the advanced networking technologies for spectrum scarcity problem constrain in the Federal Communication Commission (FCC). The cognitive radio networks are the cognitive network which abjects its network parameters with respect to the network environment. In cognitive radio network two users namely the primary and secondary or cognitive users will access the available spectrum to communicate each other when the spectrum is accessed by the primary user the secondary user must leave the spectrum and access the spectrum when spectrum holes available for transmission. So routing is challenging issues in cognitive networks and it is very challenging in mobile cognitive networks due to the node mobility, primary user interface and spectrum scarcity in this paper some routing protocols based on mobile ad hoc cognitive networks and a review on the delay-Minimized routing protocol are presented. Cognitive Radio Networks (CRN) is the new technology used to overcome the spectrum scarcity problem in current wireless networks by the Federal Communication Commission (FCC). In cognitive radio network is a network which has primary and secondary users which access the network based on Dynamic Spectrum Access (DSA). The primary user is the licensed user and secondary user is unlicensed user when the licensed user is accessing the spectrum the unlicensed user are not allowed so the secondary user has to sense the spectrum periodically to find the presence of primary user, presence of primary user is in dynamic in nature so the spectrum holes created by primary user is dynamic so the Cognitive user uses the DSA. While using the DSA routing is the challenging in cognitive radio networks. Classification of Cognitive radio networks Cognitive Radio Networks (CRN) is of infrastructure and infrastructure less, in infrastructure network it has a fixed structure like base station primary users secondary users and so on, in infrastructure network it has no fixed structure. Centralized and Decentralized networks the Centralized network is the network in which has on the base station in the central and have primary users are present. The decentralized network is the network which has no centralized base station and has the secondary users to communicate and primary users Static and dynamic networks the static networks the position of the base station, primary users and secondary users are fixed but in the dynamic (Ad-Hoc) the position on primary users and the secondary user will change (Mobility is nature). Routing in Cognitive radio networks Routing in Cognitive radio networks is based on available spectrum and knowledge of spectrum to nodes in the network. Routing solutions for the Cognitive radio networks are of two types one is Full Spectrum Knowledge routing and second is Local Spectrum Knowledge routing. Local Spectrum Knowledge routing has Minimum Power Routing, Minimum Delay-based Routing, Maximum Throughput-based Routing, Geographic Routing and Class-based Routing. Spectrum-Aware Routing (SPEAR) Spectrum-Aware Routing (SPEAR) is an on-demand and link-based protocol support end-to-end throughput by integration of flow-based and link-based approaches, it used RREQ for route discovery by control channels it takes decisions with the collaboration of PHY and MAC layers it handles mobility issues with Timeout field in periodic channel reservations messages. It takes the best path by maximum throughput, minimum hop count and link quality it has a communication overhead by route setup and route tear down. Spectrum-Aware Mesh Routing (SAMER) Spectrum-Aware Mesh Routing (SAMER) is a link state routing protocol with a minimum hop count and spectrum availability it gives end-to-end thought with the path with high spectrum availability, long-term stability and short-term opportunistic utilization of spectrum. The routing decisions are taken by PHY and MAC layers. Spectrum-Aware On-Demand Routing Protocol (SORP) Spectrum-Aware On-Demand Routing Protocol (SORP) is an AODV protocol with control channel which uses the path delay and node delay (switching and back off delay) for path selection. In route discovery phase RREQ message is broadcast with an SOP append in the packet the control channel exchange the routing protocol messages and it gives end-to-end thought put SORP doesn’t have link failure handling mechanism. Multi-hop Signal-transceiver Cognitive Radio Network Routing Protocol (MSCRP) Multi-hop Signal-transceiver Cognitive Radio Network Routing Protocol (MSCRP) is an AODV protocol with on control channel. It is a spectrum aware routing and leaves/ joins messages of the nodes so it has the communication overhead of RREQ. In the route discovery phase, all nodes append their sate information and available channels set. The routing decision is taken with the collaboration of MA C, Physical and Network Layers. Routing in Opportunistic Cognitive Radio Networks Routing in Opportunistic Cognitive Radio Networks is an on-demand graph-structured network protocol which uses the routing metric based on the probabilistic definition of available capacity over channel it has no link failure handling capacity and it discovers the route by using OSPF, Dijkstra-link algorithm. By using this Dijkstra-link algorithm it gives end-to-end throughput Local Coordination Based Routing and Spectrum assignment in Multi-hop Cognitive Radio Networks Local Coordination Based Routing and Spectrum assignment in Multi-hop Cognitive Radio Networks is a modified version of AODV which is on-demand routing protocol it has full mesh topology which uses channel scanning and beacon broadcast for neighbor discovery with control channel used for load balancing in routing. The route discovery is done by using RREQ and route decision is based on MAC and Network Layer. It has a link failure handling capability which gives less end-to-end delay and performance. Multipath Routing and Spectrum Access (MRSA) Multipath Routing and Spectrum Access (MRSA) is Mesh routing protocol based on round robin fashion data striping with minimum hop count by route discovery with control channel, Broadcasting RREQ messages. The messages sent to nodes periodically it can handle path failures by sending RERR messages and it has a communication overhead based on multiple flows on a single radio. Cognitive Tree-based Routing (CTBR) Cognitive Tree-based Routing (CTBR) is the tree-based routing protocol with centralized routing it broadcast the root announcement (RANN) message periodically with a packet and used cumulative metric for path selection. It selects the path based on local and global decision schemes. It does not have a route recovery mechanism to handle link failure s and it has a control bytes transmission overhead. Fault-Tolerant Cognitive Ad-Hoc Routing Protocol (FTCARP) It is a fast and efficient routing protocol for route recovery in presence of path failures during data delivery. It uses different route recovery mechanisms for different path failures. Cognitive Destination Sequence Distance Vector (C-DSDV) Protocol It is a table-driven routing protocol. To optimize the system performance of multi-hop CR ad-hoc networks by using multichannel routing table are updated immediately when there is a change in channels the techniques is that combines the routing and channel allocation. In route discover phase common control channel use to broadcast the route updating in the routing table in this protocol best path selection is based on sequence number. In C-DSDV channel switching is used to improve the system performances. If there are more primary users routing overhead will be increased Cognitive Ad-Hoc On-demand Distance Vector (C-AODV) Protocol Cognitive Ad-Hoc On-demand Distance Vector (C-AODV) Protocol is based on AODV a wireless network protocol it is designed according to avoid primary users activates regains for routing formation and packet discovery. It gives the minimized route cost by forwarding packets through the joint pat h and channel selection at each node it takes the advantage of the availability of multiple channels to improve the overall performances. SER-Spectrum and Energy Aware Routing Protocol SER is an on-demand routing protocol which provides high throughput in multi-hop networks it selects an energy efficient route and assigns channels and timeslots for a connection request. The communication segment assignment algorithm is used for balances traffic load among the CR users. In route discovery phase it broadcasts Route Request Messages to other nodes so it has routing overhead of RRE, RREP, RERR and ROP messages. GYMKHANA Protocol GYMKHANA is an on-demand routing protocol and an enhanced version of AODV used the GYMKHANA algorithm using virtual graphs and evaluate the cost by using the Laplacian matrix. It has a secondary user’s self-interference overhead. UNITED NODE Protocol UNITED NODE Protocol is a distributed and efficient based interference-aware routing protocol. It incorporates the spectrum availability cost and interference metrics into the routing algorithm to find better routes between the nodes it repairs routes by using route preservation method. It provides adaptability to the environment and increases throughput and reduces data delivery latency. DELAY-MINIMIZED ROUTING PROTOCOLS FOR MOBILE COGNITIVE RADIO Ad-Hoc NETWORKS POPCORN Protocol ROPCORN Protocol is the on-demand routing protocol which was designed for data transportation using link modeling and used to minimized delay for a set of users in the network. It broadcast the packets in link with the low cost and no primary user is affected. POPCORN is based on RACON protocol it uses buffers in the intermediate nodes and forwards the packets there is no overhead due to the use of spectrum availability and load estimation, the optimal route selection is based on the spatial or temporal locality of link disconnection. SEARCH A Routing Protocol It is the on-demand routing protocol and an enhanced version of AODV which is based on the geographic routing and follows the greedy forwarding and PU avoidance for joint channel-path optimization algorithm to find the best path. SEARCH undertakes both the path and selection to avoid PU activity region and tries to maintain end-to-end latency it has routing overhead due to the RRE, RREP, RERR and ROP messages. Link Prediction-Based Ad aptive Routing Link Prediction-Based Adaptive Routing is based on the link-availability prediction. The link –availability prediction considers primary user activity and user mobility. This routing reduces the energy consumption and gives the least delay by enhances network performance. It works based on link prediction and topology control Joint Routing and Channel Assignment Joint Routing and Channel Assignment (JRCA) approach based on delay prediction and a heuristic algorithm which used the collision probability and Link Stability Prediction. It is an on-demand routing protocol which user AODV type of routing with heuristic values and can find out the path with minimal end-to-end (e2e) delay. Adaptive Delay Tolerant Routing Protocol (ADTRP) The ADTRP algorithm finds a stable sequence of instances of the mobile graph and the communication topology of interest such that the number of transitions from one instance of the topology to another in the sequence is the global minimum. The algorithm uses the average lifetime of the mobile graphs in the stable sequence for communication topology and it is a generic for a stable sequence of any communication topology it uses the heuristic topology for routing so it improved throughput, better packet delivery ratio, decreased packet drop and reduced delay. STOD-RP: A Spectrum-Tree Based On-Demand Routing Protocol STOD-RP is an on-demand routing protocol which was designed for reduces the control overhead and average end-t-end delay minimization and it is an extension of the original Ad-hoc On-demand Distance Vector (AODV) protocol which uses spectrum tree addresses, spectrum decision and route selection in an efficient way for this route matrix is used. Fast and efficient spectrum-adaptive route recovery method is used when the path is damaged. In routing is challenging issues in cognitive networks and it is very challenging in mobile cognitive networks due to the node mobility primary user interface and spectrum scarcity this paper concludes that every protocol is designed for overcome certain problem in networks one is for multiple problems and one is for single problem like improving performance, minimized end-to-end delay, overall throughput increasing and so on. There is a for more protocols or improved versions of protocols for increasing problems and recruitments. In further work on this paper, a delay minimized routing protocol is proposed and implemented that improved version protocol in NS3 will be presented

Tsunami Disasters Essay Example | Topics and Well Written Essays - 750 words

Tsunami Disasters - Essay Example In particular, the port of Chennai on the east coast of India sustained moderate damage. The local fishing fleet was affected, with a number of boats overturned or washed ashore within the harbor. Overall economic losses from the 2004 Indian Ocean Earthquake and Tsunami disaster are estimated at$10 billion, with 75% of the loss attributed to the damage inflicted by Indonesia, Thailand, Sri Lanka, and India. The Southwestern costal area of the island Hokkaido was affected by the earthquake. The most affected area was in east of island Okushiri and was 100 by 125 kms. Waves soared high. They were from 5 to 12 m high and inundated the area around the island. The highest wave run-up along the southwest coast and was about 30.5 m on a limited area. Most of the deaths were on Okushiri island. The number of missing was expected to be higher because it is a tourist area. Â  540 houses were destroyed by tsunami and fire caused by earth quake, 154 houses and other properties were heavily damaged and 1,826 were slightly damaged. 31 public buildings were damaged and some were severely destroyed. Highways were destroyed in at least 365 locations and Railway lines were completely damaged at 124 locations. Port facilities and all other infrastructure in direct path of tsunami were extensively damaged, including power, water, telecommunications, transportation, and sewage. Tsunami didn’t damag e the sewage treatment plant at Apnea. Naturally high sand dunes protected it The powerful Earthquake of Hokkaido occurred in south west, the Sea of Japan. The earthquake’s epicenter was at a depth of 34 km on the Sea floor and was very close to the Okushiri Island. The island was hit by tsunami in less than 4 minutes after the earthquake and that left no time for the people of the island to evacuate. Many homes were constructed along the sea side which explained the high toll of victims. Despite only
