Eye Injury Risk from Water Stream Impact Essay

Ocular injuries caused by solid projectiles have been described in the literature (Duma, 2005; Kennedy, 2006; Kennedy, 2007). However, the impact of a high-velocity water stream on the globe has not been previously quantified. Such pressurized water jets can be found in children’s water toys, squirt guns, and interactive water fountains. As the velocity of these water streams increases, product capabilities, and therefore popularity, likewise increase. In addition to those on the market, water gun enthusiasts custom build powerful guns in order to maximize flow rate, often in excess of 55 ft/s. Interactive water fountains (also called wet decks, splash pads, spray pads, or spray parks) are found in public areas and water parks throughout the country. The attractions feature synchronized jets of water, typically directed vertically from nozzles in the ground. While playing, it is possible for a child to look into the nozzle in anticipation of the next spurt of water which could in theory cause an eye injury. However, the increasing popularity of these fountains has not been matched by appropriate regulation. The CDC recommends that health departments update pool codes to include interactive water features that do not have standing water (Prevention, 2007) due to a series of outbreaks of gastroenteritis (Minshew, 2000). The lack of research and injury assessment has delayed the process, as most states have not established codes. Current available legislation is listed in Table 1. The primary focus of concern in current legislation is centered on the filtration system and prevention of spread of bacterial infection. This concern has taken attention away from the potential for mechanical injury due to a high-velocity water jet directed toward a child’s eyes, ear, or mouth. This study consisted of five parts: Part I includes previous research and case studies that have been reviewed to begin to understand the need for water eye injury research and the previous efforts made to investigate this injury mechanism. In Part II, a range of objects and devices were analyzed to determine water characteristics and the associated injuries. A summary table of the results was produced. In Part III, projectile impact tests were performed with three different projectiles and a range of velocities to measure normalized energy and internal pressure within the eye. For Part IV, water jet impacts were performed with three nozzle diameters and a range of water velocities to measure internal eye pressure to assess injury. In Part V, data from Part III were used to determine a correlation between normalized energy and internal eye pressure to then calculate normalized energy for the measured internal eye pressure during the water jet impacts (Part IV). Previously developed injury risk curves for corneal abrasion, hyphema, lens dislocation, retinal damage and globe rupture were applied to the calculated normalized energy to determine injury risk for the water jet impacts. Nozzle type, size, and maximum velocity are a critical part of an interactive water fountain’s performance, but until relationships between these factors and injury have been established, it is hard to place numerical guidelines on their design. This report aims to quantify the incidence and mechanics of water-induced eye injuries and benchmark the fluid mechanics of current water systems and toys. Documented cases of high-velocity water-induced eye injuries confirm the potential danger of these water blasts (Table 2). Many of the reported incidents occurred in the workplace and involve pressure washers, agricultural irrigation sprinklers, or fire hoses. While studies of water-induced eye injuries on humans have not been conducted, animal studies have linked high-velocity water jets to eye damage. Fish (Oncorhynchus tshawytscha) exposed to submerged water jets at velocities ranging from 40 to 65 ft/s were examined for injury. Nearly half of all fish suffered eye injuries (bulged, hemorrhaged, or missing) at velocities of 55 ft/s and above (Deng, 2005). In a similar study, fish were released at velocities from 0 to 70 ft/s and the authors found velocity to be positively correlated to severity of injury (Nietzel, 2000). Minor severity was noted when there was a visible injury that had no threat to life and major severity was noted when the injury was a threat to life and persisted throughout time.

Concept Essay †Importance of Eating Healthy Essay

Concept Essay – Importance of Eating Healthy When thinking of the concept of â€Å"eating right† many people think it simply means consuming tasteless foods and useless fruits and vegetables. But eating healthy is much more than that. Eating healthy means more than consuming the recommended fruits and vegetables, but it also means having a balanced diet that is right for the body; for eating healthy is not one size fits all. By eating healthy, people are able to: supply their bodies with the nutrients needed to grow and develop; reduce their chances of developing chronic illnesses and diseases; and maintain a healthy weight. Eating healthy provides the human body the nutrients needed to grow and develop. According to Dr. David Tayloe of Parenting Magazine, eating healthy starts in the infancy stage of our lives and continue into adulthood. Dr, Tayloe (2011) outlines the most important nutrients babies need: iron, calcium (helps strengthen our bones), zinc (works to improve our immune system and optimize our cell growth and restoration), and vitamins A (helps our vision), B (enhances our immune and nervous systems, helps improve our skin and muscle tone, and regulates our metabolism), C (improves iron consumption and prevents body from bruising), D (helps with bone growth), E (facilitate cell growth and work to improve our nervous system) and K (helps our blood clot). The minerals and nutrients that are needed for our bodies are derived from many foods, such as breast milk, baby formula, vegetables, meats, whole grain, fish, eggs, fruits, whole milk, cheddar cheese and fortified cereal. Without the recommended servings of these nutrients, our bodies will not be able to grow and function properly. Making important decisions during meal time is essential to our daily life functions. For example, having a breakfast that is low in fat but rich in healthy nutrients can help improve overall thinking, help us remember more things, stimulate our creative thinking, give us energy and help our overall mental state. According to the President’s Council on Fitness, Sports & Nutrition (2013), our food choices each day affect our health — how we feel today, tomorrow, and in the future. When we do not eat healthy, we are more susceptible to certain health risks. The President’s Council on Fitness, Sports & Nutrition reports the major health risk associated with unhealthy eating habits includes â€Å"heart disease, hypertension (high blood pressure), type 2 diabetes, osteoporosis, and certain types of cancer† (2013). Eating one candy bar does not make a person have bad eating habits; just like eating one serving of broccoli does not make a person a healthy eater. Eating unhealthy foods on a consistent basis is what leads to chronic health problems. In his article, John Phillip (2010) provides a list of food additives that should be avoided. This list includes artificial sweeteners, Monosodium Glutamate, or MSG, and Trans and hydrogenated fats. Foods that contain artificial sweeteners can lead to diseases such as lymphoma, diabetes, multiple sclerosis, Parkinson’s and Alzheimer’s. The foods that fall under this list include sugar-free drinks, foods found in bakeries, and even gum. Phillip (2010) reports that these foods can increase brain aging. MSG is found in many foods, as it enhances their flavor. On many food labels, instead of MSG, the term â€Å"natural flavor† will be used; though MSG is not a natural ingredient. High consumption of these foods can lead to depression, disorientation, eye damage, fatigue and headache. Trans and hydrogenated fats are found in fried foods and commercially baked foods. According to Phillip (2010), these foods can increase the chances of heart attack by 25%. There are many factors that affect one’s body weight, including stress, genetics and hormones. However, large consumption of foods that are high in calories and fat can lead to obesity as well. When a person eats too much of the wrong food, or foods high in calories, without burning those calories by being physically active, then those calories are stored in our bodies as fat. According to the Center for Disease Control and Prevention, eating the wrong foods has created an obesity epidemic in the United States: â€Å"about one-third of U.S. adults (33.8%) are obese and approximately 17% (or 12.5 million) of children and adolescents aged 2—19 years are obese† (2011). Although exercising is good for combating obesity, making good eating choices can help combat obesity. In addition to watching calories intake, there are several ways eating healthy can be beneficial to combating obesity. For example, eating breakfast daily can provide us with energy to burn the calories that we will intake throughout the day. Eating smaller,  low calorie meals throughout the day can combat obesity; instead of eating three really large meals at breakfast, lunch and dinner. Avoiding drinks that are high in sugar and calories, such as juice and soda can aid in combating obesity. Finally, eating smaller portions can help ward off obesity. By making these few changes in their diet, one can be on the road to eating healthier and becoming a healthier person. There is an old clichà © that says â€Å"we are what we eat†. If we eat healthy, then we are healthy; however, if we eat unhealthy, then overall we are unhealthy. If we eat foods high in fat, cholesterol, calories we will find ourselves at risk for developing diseases that are linked to those eating choices. Getting on the road to healthy eating can be as simple as cutting back on all the junk we eat that is high in salts, fats and sugars. It is important that we make good food choices so that we may live happier and healthier lives. References Centers for Disease Control and Prevention (2011). . U.S. Obesity Trends.

MA thesis proposal Research Example | Topics and Well Written Essays - 750 words

MA thesis - Research Proposal Example Social media plays an important role in public relations department in private and public sectors. Internet service is not limited to entertainment and information but moves on to providing electronic services. The government of Saudi Arabia has, for example, realized the importance of internet and has given it special attention. Public relations specialists also believe, according to Alenizi, that internet applications have a high ability to elevate work quality and speed of the organization to deliver services to their customers. A study by Alshehri also shows that the use of electronic application contributes in minimizing the cost and elevating the quality of production (Jenaibi, 2013). Consequently, and according to http://www.yesser.gov.sa, an electronic government program drawn from the royal decree number 7/b/23181 in 2003 stated that all government entities have to provide electronic services through the ministry of communication and information technology (Saud & Khan, 2013 ). Saud and Khan (2013) showed that the use of social media in Saudi Arabia is rising with increase in the access to mobile phones. In 2012, the number of Facebook users in the kingdom of Saudi Arabia was 6 million and in 2013, the number increased to 7.8 million. Similarly, Saudi twitter users increased from three million in 2012 to five million in 2013. The country’s use of Instagram increased from 4 million users in 2012 to 5.7 million in 2013. According to Shorkey and Uebel (2014), many companies in Saudi Arabia, public and private, use social media for marketing. The study highlighted Flynas, STC, McDonald’s and Toyota as the top brands on Facebook. Jenaibi (2013) highlights Aramco, SABIC and STC as the top ranking companies on Twitter. Companies that deal in cosmetics and cars are the ones that rank high in the use of Instagram in Saudi Arabia. A single privately owned company in the country can have up to

Second Language Acquisition 'Interlanguage and explicit knowledge' Literature review

Second Language Acquisition 'Interlanguage and explicit knowledge' ( part) of the project - Literature review Example First of all, the project looked at the Second Language Acquisition (SLA), the notion of competence as well as a detailed description of interlanguage and explicit knowledge. Furthermore, the collected data was analyzed and the results of the research were provided, in particular TLU results of the occurred errors were explored to identify the gaps and variability in the speaker’s implicit knowledge. Last but not least, the study looked at the identified errors made by the L2 speaker and explored to what extent those errors were consistent or whether, they showed any patterns to the variability. Lastly, the implicit and explicit knowledge were compared and the implications for SLA were researched. Literature review on SLA, Interlanguage, Explicit/Implicit Knowledge (this part needs to be corrected, all that is highlighted, especially in red). 16Second Language Acquisition (SLA) Second language acquisition (SLA)process refers to the way that6someone acquires one or  a few for eign  or  second  languages. Scholars who study second language acquisition look at the  process of  acquisition in a  classroom setting and in the context of natural environment where learners use the language in a casual conversational interaction (Carter and Nunan, 2001: 87). The notion of communicative competence in the second language acquisition, tends to include sociolinguistic and grammatical competences, insofar as the abilities in a second language (L2) to evoke using language in socially and linguistically appropriate ways (Brown, 2006: 195). Figure 1: Components of Language Competence Source: Brown (2006: 195). Figure 1 shows the sub ­categories of language competence which are the common paths to be followed when analyzing the learner’s ability to use the language. Interlanguage The orientation of the interlanguage was derived from the Corder’s (1967) Error Analysis Approach and was proposed by Selinker (1972).  It represents â€Å"a separ ate linguistic system based on the observable output which results from a learner’s attempted production of a Target Language  (TL)  norm’†(Palotti, 2010: 160). According to Corder’s Error Analysis Approach, the influence of the first language (L1) on the L2 could not be denied and the L1 can be taken as the starting point to predict the language errors made by the L2 learner (DeBot et al. 2005: 34). Selinker identified four major sources for transfer that might shape the interlanguage’s structure. These include transfer of strategy, transfer of communication, transfer of training as well as transfer of other languages that the learner has already acquired or one’s native language (Brown 2006: 225). These ‘transfers’ are the major sources for analyzing L2 learners’ interlanguage characteristics. Implicit and Explicit Knowledge There are two types of knowledge that have been identified in the second language acquisition (SLA) which lend itself to this research. The ‘implicit knowledge’ refers to a knowledge that the learner is generally not consciously aware of whereas, ‘explicit knowledge’ refers to a declarative knowledge of the language that the learner can describe if necessary and is usually aware of (Littlemore 2009: 63). The major differences between explicit and implicit knowledge are identified by Ellis consist of: (2009: 16) ? Implicit and explicit knowledge involve different access mechanisms and implicit know

Conquest of Mexico by Spanish Conquistadors Essay

Conquest of Mexico by Spanish Conquistadors - Essay Example He offered men who served under him significant training and discipline, allowing them to operate as a unified soldiers’ unit. In addition, he ensured to burn his ships to ensure that retreat was not possible for his men (Taylor). Cortes was aware of Aztecs, realizing that they together with Montezuma II, who served as their leader, served as the key driving forces of Mexico. As such, Cortes was driven by the urge to rule over them. While marching through Mexico, he experienced several natives referred to as Tlaxcala, who served as Aztecs’ enemies. In this case, this group served as a vital ally during his Tenochtitlan siege, which was then the capital city of Aztec. Without the knowledge of Cortes, Aztec’s prophecy coincided with his arrival. Quetzalcoatl, who was the god of Aztec, who they are associated with the creation human life was about to come back to earth. Since Montezuma thought that Cortes was Quetzalcoatl, they welcomed him while showing him great h onor. Montezuma sent various representatives to welcome Cortes as he approached. The light skin of the Spaniards while riding horses amazed the Aztecs, which they considered as beasts having six legs and two heads. To intimidate as well as stun the natives further, the Spanish fired gunshots. On entry to the city, Spanish soldiers together with the Tlaxcalans dismissed it, taking Montezuma hostage. With the assistance of Dona Marina, Cortes managed to influence Montezuma to facilitate in ruling Tenochtitlan while using him.

Neutrality of Money Concept in Macroeconomics Essay

Neutrality of Money Concept in Macroeconomics - Essay Example This paper offers a comprehensive analysis of the evolution of views of different economic schools of thought on the concept of money neutrality. Neutrality of money had been a concept popularised by classical economists who assumed that output at any point of time is being produced at the full employment level and hence, cannot be adjusted in the short run. Change in money supply could actually lead to a change in the general price level of the economy without creating any influence over its aggregate demand and supply schedules, rate of employment and interest rate. Thus, varying the amount of money in circulation in an economy could actually result to a controlled inflationary environment in the concerned nation. The primary reason behind the applicability of neutrality of money is the inelastic aggregate supply curve in the economy. A rigid supply results to a rise in price level in the nation though relative price of commodities remain fixed. On the other hand, as wages also increase proportionally, there is no adjustment on the aggregate demand frontier. Hence, the impact of a change in money supply only results to a change in the general price level in the short run. The dissection between real and nominal variables as made by classical economists led to the development of a result called classical dichotomy. The concept has been revised a large number of times by economists belonging to successive schools of thought. As it has been found that neutrality of money holds only during the long run. ... This is the reason why the concept has been revised a large number of times by economists belonging to successive schools of thought. Explanations provided by Macroeconomic schools of thought The following paragraphs elaborate the stance posed by various macroeconomic schools of thought regarding the neutrality of money. It was proposed first by the classical economists but had later been revised by its successors during different real-life economic crises. Classical Economics The classical economists were of the view that a change in money supply actually does not affect aggregate supply in the nation. In fact, they assumed aggregate supply of money to be inelastic at any point of time. In other words, the economy always produces at its full employment level so that the equilibrium output being produced is always fixed. In the short run, the position of the schedule stays fixed while in the long run, it shifts horizontally without creating any impact on the slope of the curve. Hence , a rise in money supply actually results to a shift in the aggregate demand given the immediate rise in the wage structures. The diagram alongside illustrates the situation which had been depicted by the classical economists. It shows that a rise in money supply in the economy results to a vertical shift in the aggregate demand curve. But the ultimate outcome remains unaltered with the equilibrium output staying fixed at Y* though the equilibrium price level rise from P0 to P’. Initially, a shift in aggregate demand curve creates a pressure upon the equilibrium output inducing a shift in equilibrium point from E to E†. But such a pressure cannot be

IKEA UK Marketing Analysis Essay Example | Topics and Well Written Essays - 2500 words

IKEA UK Marketing Analysis - Essay Example As the paper stresses the UK furniture and furnishing industry is substantial, thus makes a significant contribution to the UK economy, including the GDP and employment of UK citizens. There are approximately 8,116 companies in the UK furniture and furnishing industry, including retailers, wholesalers, repair, leasing and specialist designers. The furniture and furnishing industry in the UK is segmented into three major sub-sectors based on the different products and markets therein as well as the characteristics of the buyers, including domestic, office and contract sectors. Companies in the UK furniture and furnishing industry often serve more than one market. As the report declares the UK furniture and furnishing industry comprises many micro and small to medium businesses that specialize in furniture, furnishings, retail, repair and design. However, the industry is not well recognized at the political level and does not receive the government support it deserves despite its contribution to the UK economy. Nevertheless, this industry has experienced growth in imports while exports registered a slight fall in the year 2013. China, Germany and Italy are key players and drivers of the import growth while the Republic of Ireland, Germany and France are the main destinations for exports from this industry in the UK. IKEA, UK uses demographic bases including age, sex, family, job type, socioeconomic status and life cycle to segment its markets.

Essay about a study case analysis of the OIL MARKET

About a study case analysis of the OIL MARKET - Essay Example As opposed to the rest of the world which uses oil more for heat and power, Canada and The United States use oil more for transportation providing a larger market. The Northern Hemisphere provides a larger market during cold months. Developing countries provide a substantial market size but the increasing debt is making them a less targeted market (Luciani 85). The relative price of oil substitutes such as gas also affects the demand for oil. The development of reliable and cheaper oil substitutes may cause a shift in demand away from crude oil towards the emerging substitutes. Research and development of non-oil substitutes has risen since the high oil prices during 2004-2005, even though this can take years to affect the energy market. These substitutes include renewable and alternative fuels like hydropower solar wind geothermal, biomass and ethanol. Related goods can also be compliments of oil or goods that utilize oil and oil products like vehicles. If the prices of vehicles rise then the demand for oil will fall and if the prices of vehicles fall then the demand of oil will rise. This shows that related goods can either be substitutes or complements. The amount of income a country is willing to spend also determines the demand for oil and oil products. If the consumer country has more disposable income then the demand for oil will be more but if the income remains constant and the oil price rises the demand falls. Similarly when oil prices fall the amount of oil demanded for the same income will rise. This means that a relatively higher income level consequently increases demand levels and a lower income translates into lower demand for oil. This explains why developed countries demand more oil than developing countries. The dependency on oil has led to many of the developing countries to pile a lot of debts in their quest to acquire oil (Pirayoff 76). Oil supply depends with its availability and it is believed

Health Care Providers in Different Religions Essay

Health Care Providers in Different Religions - Essay Example In many cases however, one does encounter a variety of different faiths when seeking out health care. In Christianity there are seven aspects of providing health care to patients. All of these are tied to religion and the Holy Bible and its sayings. The first is a moral code of conduct and justification that will guide health care providers to tend to patients in a manner that is in alignment with religion. Such as the fact that they cannot present life threatening drugs or force people to take a drug that may cause death. At the same time, women cannot be advised of abortion etc. Secondly the doctor patient relationship needs to be built on the element of trust; the patient is entitled to receive all the information regarding treatment, health care and any aspect of a procedure that they have to undergo. Even though the provider is the true healer and is believed to be so by the patient as well, all sides of the story is a duty of the doctor to the patient. Thirdly, patients are aut onomous, that is, they are allowed to make any decision they want to, after being presented all the facts of the situation. At the same time, health care providers have to act like good citizens, taking it on their conscience to care for the patient and heal them; and not just go through with this procedure in a mechanical fashion, but to be caring and loving and compassionate towards the patient. God will only show mercy to him who showed mercy on his creation, and so providers need to offer not just treatment but compassion and mercy to patients, praying for their well-being and taking it as a duty as God’s servants to take care of his creation. At the same time there is the concept of non-maleficence in Christianity; which essentially translates into â€Å"never harm anyone.† According to this principle, health care providers need to be such that they give the right kind of prescription to the right patient and they need to assess whether a particular treatment woul d harm or benefit the patient in question. Christianity also believes in the principle of justice. Therefore patients are all to be treated equally and fairly, and treated till depth of the provider’s ability as that is their right as not just patients of the doctor, but also as human beings. He is also to provide access to the patients to health care if he himself cannot suffice. Lastly, it is believed that one, no matter what profession he follows, must have a character of integrity and virtue, so that no matter who he is dealing with, he will uphold his virtuous character and refer to the Bible and never wander from what it deems to be right and wrong. (Benedict M. Ashley, 2006) It is the general view, that all the principles aforementioned should be followed, whether the person seeking treatment is a Christian or otherwise. Doctors need to be compassionate, caring, try their best to bring the proper and complete treatment to their patients, while at the same time, upholdi ng the ethics of their profession, that is, anything that can cause harm to their patients is supposed to be out of the question. However, some cultures and religions have different aspects or an addition to the aforementioned principles. Buddhism originated through the concept of suffering, the state of the soul being in trouble rather than the body being in any agony. The Buddhists believe in both technique and discipline, and those principles along with the eight fold path determine all other aspects of life even health care. The eight fold path includes right speech, right view, right

Metaphors on Teens Essay Example | Topics and Well Written Essays - 1000 words

Metaphors on Teens - Essay Example Communicating with your teenager on a regular basis Communication is blinding family with love, care, support, and bringing a parent-teen relationship to harmonious respect. Teens are spending less time talking with their parents and more time with peers, deteriorating and disconnecting their relationship. In this scenario, communication is needed to prevent relationship from being torn. Just as food and air are necessary for human survival, so is communication necessary for the development and sustainment of a relationship. Thus, communication is like a bridge that connects two separate ways into one. Communication is a tool for showing love and interest, resolving conflicts and issues and a means of building close relationships. As supported by Norbeck and Fitzpatrick (125), in a parent and adolescent relationship communication is a commonplace means of understanding. Meanwhile, teens of today are more exposed to negative influences through factors such as technology and peer press ure --destructing powers that increase as time ages. Therefore, teens must be parented properly and should be treated and comforted like a pillow. How to parent your teens with love and compassion Children are highly precious people to their parents’ lives. ... â€Å"Am I a controlling parent? Do I listen to my child?† parents often wonder. Parents, especially those who are autocratic, want their teens to follow every command and rule they impose. However, just as if too much weight is placed on a bridge it will break, so will parents acting too strictly result in cracks in the relationship. Indeed, if parents are too strict in not considering teens’ feelings, desires and opinions, conflict may arise. Parents must show love and compassion to their teens despite disobedience. Teens want to be loved and cared by parents, and see their parents as their protective shield when it rains. There are many ways parents can show love and compassion to their teens. According to Taylor (2005), parents must teach love and compassion so that teens understand its essence. Second, parents must plan activities that establish compassion and increase love, such as family outings, family prayer and scripture study, and watching movies together etc . Meanwhile, teens might get mistaken, so it is a perfect time for parents to show love and compassion through comforting, teaching teens how to make decisions, and â€Å"encouraging them to rise after having stumbled down.† How to parent the stubborn and argumentative teenager through peer pressure At their age, teens are like the ball that keeps on rolling. Peer pressure greatly influences teens’ behavior as they might apply what they have learned from peers. Some teens are stubborn and very augmentative. Parents of this kind have hard times negotiating with them. According to Thompson (2006) some teens often love to argue and persist in their ideas. They want to be always right, and do the things they want. Parents want the best for them, so generally what they consider is the best and

Trends In Merchandizing Essay Example for Free

Trends In Merchandizing Essay Over several years ago, manufacturers and retailers have been putting more emphasis and placing increased importance on the in-stock merchandizing and marketing. Since mid 1990s, the effectiveness of traditional marketing has really declined. Also the competition between retailers and channels has been increasing which have been treated as the factors in driving the trend. According to Bishop Willard in October 2002, he noted that more consumers make around 70% of all purchasing decisions while in store shopping. This has been the main reason as to why stores are the new platforms for brand marketing while the difficulties in delivering effective in store solutions for merchandizing increases, and also the need to implement state-of-the art merchandizing software capable of strategizing, planning, visualizing and communicating such solutions arises (Varien 2001, pg 45).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Interactive edge in merchandizing has built many interactive sales applications for the top consumer package goods manufacturers for about ten years ago. Since the year 2002, there has been an increase in demand for interactive requests which focused entirely on planning and communicating merchandizing solutions. The ability to create account specific market plans is very crucial because each customer has specialized schedules, strategies, programs, objectives and store and market conditions. Marketing plans are ideally supported by customer and category insights, analysis of promotion that speak in the situation of the customer, sales goals and brand information. The marketing plans that are informed by customer insights and account specific category have greatest impact in setting the stage for activities in merchandizing. In any marketing planning, it is important to implement the existing opportunities and conditions for each customer by first assessing the customer’s current merchandizing solution.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Smart bargains have managed thousands of dollars of continual changing inventory on daily basis. The firm’s experienced buyers should act on a moment’s notice to buy a wide range of high quality products at unexpected discounts. At the midst of controlled disorders at the core of this changing business, smart bargains required a solution to enable buyers, senior executives and planners to report and manage future and historical merchandize plans in a responsive, efficient and highly flexible manner. Smart bargains has turned to Envisa to implement and architect a business intelligence suite through use of Microsoft server 200 analysis and Microsoft table in excel.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The solution which leveraged merchandizing data mart had been developed during earlier incentive which provided smart bargain with a powerful reporting architecture that untied business users from the need to make complex questions in custom report writing. Merchandizing strategy creation does not imply a complete decorator make over. In order to enhance customers’ image of store, one should perceive his own store the way the customers see it and provide the customers with their requirements. According to research by Russel M who is a retail hardware operator, the consequences of a customer satisfaction survey came up with seven aspects customers want their hard ware stores to play for them. The customers require hardware stores to offer services which are special, make enjoyable shopping, have provision of one stop shopping destination, help them to save time, help them to save money, assist them better to understand d-i-y projects, and also make shopping easy (Phelps 1963, pg 78). At global shop, retail design experts, annual retail design exposition co-produced by design ideas and display conducted studies on why and how today’s consumer shop and also how a store can merchandize its goods so as to best meet the customers requirements. Those designers came up with emerging merchandizing trends to assist the retailers in all firms and industries to provide their customers with the kind of shopping experience they need. It is very important to keep up to date with these trends because as the number of shopping choice in the market grows, clients will find the most enjoyable and satisfying experience for shopping. This is also a better way of reaching ones store’s changing customer base. This includes more shoppers of females and also the next shopper’s generation who would expect more interactive and entertaining shopping experience.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   In order to maintain home improvement shoppers from shifting to other shopping alternatives like big boxes, the internet and mass merchandisers, the retailers require incorporating an updated merchandizing strategy so as to cultivate customer loyalty and sales based on preferences of consumers. Some of the emerging trends, with details on how the home improvement industry is incorporating these trends are outlined below. Accommodation for shopper’s need for entertainment competing with the increasing popularity of increasing sales during an uncertain economy and internet shopping one the only two major factors that drive the today’s trend towards entertainment in retailing according to Schaffner K who is the publisher of design ideas and displays searching for ways to get customers to interact with the produced products is the core of the retail tainment concept, according to Schaffner. He added that this strategy does not hurt while conducting it. Such thinking was behind sears’ new tool territory format which so far has implemented in 131 stores of mall nation wide with around 200 additional stores slated for format incorporation this year (Brand 1963, pg 85).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   The tool territory concept was created from consumer’s point of view and its caters to how the stores target clients –male-d-i-years-prefers to stores. The purpose of designing the tool territory was to be an interactive playground for men according to Costello Larry who is a senior manager in communications for sears. He further explains that, sears created a tusk force to research for customer’s requirements and expectations especially when shopping for tools. The study concluded that, individuals want to interact with tools and also experience their features in the stores. In incorporating these hands on approach to buying tools, sears have positioned a strategy of â€Å"try me† stations in several locations within the hardware department. For instance, if a client is deciding which item to purchase, like hammer, he or she can first try it our by hitting it on a free standing metal spike that has been placed in front of hammer display. Prospective buyers of power drills can pick up on the drills displayed outside the boxes on light displays with signed, and use it to make a hole in a well placed block of wood (Shilburg 2003, pg 231).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   With all consumer packed goods or items available and the notice able changes in effective displays of merchandizing and the market place promotions, it becomes very hard for a consumer to come up with proper decisions. Manufacturers and retailers should start to cut through this clutter by having simplified shopping experiences the latest research conducted from the information researchers has not covered the early indicators that point to consumer centric approach to emerging merchandizing consequently, merchandizing as it is defined today is likely to undergo major of transformations. By considering the emerging trend, trends report and the latest times and also the growing demand for a consumer centric approach, the world’s largest provider of enterprise market information services and solutions for the customer package goods, health care industries and retail, explores trends in practicing merchandizing, including displays, new practices of innovations like manufacturers embark up on this transformation, customer packaged goods and temporary price reductions. As the retailers reduce the grocery display space, manufacturers require innovative merchandizing devices that should have a stress to the importance of consumer centric merchandizing to provide more profitable rewards in order to feature and complete space during the next several years.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   Marketers should step up merchandizing innovation in have the shopping experience simplified, to have a break through the clatter and have better alignment with consumer segments and their patterns of shopping. The Information Resources Inc report aimed at helping the consumer packaged goods manufacturers and retailers to see new risks and opportunities that will arise with the new trends of merchandizing so that they can be able to act on the insights with confidence and speed and win at the shelf (Beck man 1967,pg 421).   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   For the past several years, merchandizing activity has been declining in more than half of all the customer packaged goods categories as the CPG marketers start to realize that, more of anything is not better with respect to merchandizing. Through development of new store formats and pronounced focus on perimeter upscale and departments, uncluttered layouts, a competition for shrinking grocery display space has intensified for various categories. Merchandizing is perceived as an effective sales driver as the majority of consumer categories gain an average volume lift of around fifty percent or more with around 25 percent reacting 100 percent when the tactics of merchandising are applied.

Transmission control protocol

Transmission control protocol Comparisons and Evaluation of TCP versions Tahoe, Reno and NewReno Abstract There is been several numbers of transmission control protocols proposed for the past several decades. These proposed TCP versions have been widely acceptable and used in packets switched network. In this paper we will present an overview of Transmission control protocol, discus different versions of transmission control protocols which are current used, explore the challenge faced when deploy these TCP versions and finally compare and evaluate these TCP versions. Index Terms Transmission control protocol (TCP), TCP Tahoe, TCP Reno, TCP Vegas, TCP NewReno, slow start, fast retransmit, fast recovery and congestion avoidance. I. Introduction Transmission control protocol (TCP) is a connection oriented protocol which was designed to facilitate reliable and secure end-to-end communication between to device in a packet switched network [1]. The reliable communication between devices is achieved by TCP through process of assigning sequence number to every packet that is transmitted and record the time used to transmit packets between source and destination, further to that, TCP protocol require Acknowledgment of receiving packets from destination host to complete communication. By using this mechanism transmission control protocol is able to detect the packet lose, damage, duplication or received out of order and be able to correct them or retransmit. Transmission control protocol also use sliding window control mechanism to control the number of packets sender device can send at one time and keep regulating this number for any further changes in a network. This is achieved by requiring the destination device to acknowledge the receiving of all packets sent by sender. This number is usually telling sender device the number of approved packets can be transmitted before get permission to increase or decrease. There are different types of transmission control protocols which were proposed in order to try to improve the transportation of packets in a packets switched network. Some of these TCP versions which were proposed are including TCP Tahoe, TCP Reno, TCP NewReno, TCP Sack and TCP Vegas. II. TCP Tahoe This is a type of TCP version which was proposed to improve the original TCP protocol which was mainly based on assumption that packets lose is only caused by congestion in the system [2][3]. The original TCP protocol used to follow go-back-n automatic repeat request model which was able to detect loss of packets from timeout, retransmit only if there is packet loss and receiver host govern the window control packet flow in order to prevent packet overflow at receiver buffer. This protocol did a little to reduce the congestion if the two end-to-end devices were in different networks or data packet are required to go through a router to get to other end or go through a slow link. In the process of trying to improve the original TCP three traffic management mechanisms slow start, congestion avoidance and fast retransmit were introduced to the original TCP and the new TCP version was named as TCP Tahoe. Slow start Most of the original transmission control protocols were used to start connection followed by sender start injecting several packets to the network until sender reaches the window size allowed by receiver [4]. This approach can work fine if end-to-end devices are within a single Local Area network but in a fast and slow link network with multiple local area networks this approach can encounter problems which may resulted into rapidly reduction of TCP connection network throughput. In order to avoid these problems of throughput reduction slow start mechanism is used in a TCP Tahoe. Slow start operating mode always starting injecting packets into a network with window size of initial value of one then waits for its acknowledgement before increases its window size value. When sender receive the acknowledgement that the packets was received by destination then it increase its congestion window to two and send two packets, if acknowledgement received for these two packets, sender increase its congestion window size to four. Slow start mechanism keep increases its window size every time it receive its acknowledgement of previous sent packets exponentially until it reaches its maximum threshold value and enter congestion avoidance mechanism. By using slow start mechanism TCP Tahoe reduce the rate of congestion in a network. Congestion Avoidance Congestion Avoidance (CA) is another control mechanism used by TCP Tahoe to gently inspect the network for spare capacity [5]. TCP Tahoe enters into congestion avoidance mode when the value of congestion window size is greater than the value of slow start threshold otherwise TCP Tahoe continues working in a slow start mode. If packets loss is detected in the network then TCP Tahoe algorithm will automatic assume there is congestion somewhere in the network, using this assumption TCP Tahoe change its slow start threshold value to half of its current value and set the congestion window size to its initial value and start slow start again. Slow start and congestion avoidance are two independent algorithms with each have their own objectives; but when congestion occurs in the network TCP Tahoe is required to slow down its rate of sending packets into the network by call upon the slow start mode of operation to get thinks going again. Fast retransmit One of the problems with TCP timeout-triggering retransmission mechanism is that the timeout period can be relative long. Subsequently if there is any packet loss in the network, it will take long period of time before sender retransmit the loss packets hence increases end-to-end delay [6]. In order to solve this long timeout period retransmission problem TCP Tahoe uses fast retransmit mechanism to resend any loss packets. It doing so by allowing sender to use so called duplicate Acknowledgements to detect packet loss well before the timeout event occurs. Fast retransmit operating mode in a TCP Tahoe can be triggered when three or more duplicate Acknowledgments are received by sender in a row. If this occurs then TCP Tahoe will perform retransmission of what is assumed to be missing packets without the need to wait for packets retransmission time to expire. During this period of fast retransmit TCP Tahoe adjust its slow start threshold to half of current value and enters the slow sta rt mode of operation and set the congestion window back to its initial value of one. TCP Tahoe problems Due to automatic set back to slow start mode of operation with initial congestion window of one every time packet loss is detected we see TCP Tahoe does not prevent the communication link from going empty. Hence this may have high cost in high bandwidth product links. III. TCP Reno TCP Reno has all three mode of operation integrated into TCP Tahoe like slow start, congestion avoidance and fast retransmit, but in addition to that TCP Reno modify the fast retransmit mode of operation to form fast recovery mode of operation[7]. TCP Reno enters into fast recovery mode of operation when sender receiving three duplicate acknowledgments. Fast recovery operates by assuming congestion is serious in a network if the packets loss is detected due to timeout. If this is true then fast recovery mode set TCP Reno congestion window size to its initial value and enters into slow start mode of operation. But if the congestion is detected due to duplicate acknowledgements then TCP Reno assume the network congestion is not serious. If this is true fast recovery mode set TCP Reno congestion window size to half of its current value and enters congestion avoidance operating mode instead of slow start mode. By entering congestion avoidance mode of operation TCP Reno prevent the commun ication link from going empty after packet loss by avoiding slow start. TCP Reno problems TCP Reno only performs better when there is single packet drop from window of data, because it cannot detect multiple packets drops from single window of data. Due to this if there is multiple packet loss from single window of data then TCP Reno is required to wait for timeout to retransmit the second packet which has been lost, subsequently TCP Reno over high packet loss network does not perform well, it almost works just like TCP Tahoe. IV. TCP NewReno TCP Reno has all the key algorithms found in TCP Reno but in addition to these algorithm TCP NewReno modify the fast recovery algorithm in order to solve the problems of TCP Reno of not be able to detect multiple drop of packets in a single data window [8]. TCP NewReno enters fast recovery mode of operation just like TCP Reno when it receive 3 duplicate acknowledgement, but unlike TCP Reno, TCP NewReno does not exit from fast recovery mode of operation until all the packets which are not acknowledge by the time fast recovery was entered are acknowledged. After receiving acknowledgments of all outstanding packets TCP exit fast recovery mode of operation and set congestion window size to its initial value and finally enters the congestion avoidance mode of operation to get thinks going again. TCP NewReno problems TCP NewReno suffers from the fact that it is taking one round trip time (RTT) to detect each packet loss. Therefore TCP NewReno can only work out which other packet have been lost when sender receive the acknowledgement of first retransmitted packet. V. TCP SACK TCP Reno only work better when there is single loss of packets in a single data window and does not work better when multiple packets get dropped in a single data window without going into timeout retransmission. TCP Sack was implemented in order to solve this problem by improve retransmission efficient when multiple packets losses occurs [9] [10]. It is doing this by introducing Sack option field in a TCP Sack which is used to report out of order block of data which have been received correctly by destination device. Therefore instead of retransmit all non acknowledgment packets TCP Sack retransmit only packets which are missing. Similar to TCP Reno, TCP Sack enters fast retransmit mode of operation when sender receive three duplicate acknowledgements. The sender in TCP Sack retransmits packet losses then reduces its congestion window to half before exit fast recovery only when it receive acknowledge that all outstanding data packet have been acknowledged. VI. TCP VeGAS TCP Vegas is one of the most sophisticated transmission control protocol which uses packets delay to determine the rate at which sender send packet rather than using packet loss as discussed in TCP Tahoe, Reno, and NewReno [11]. It uses the initial increase packets Round Trip Time value to detect the congestion in the system instead of using packets loss. TCP Vegas achieve this by using the following techniques. * More Accurate Round Trip Time (RTT) Calculation * New mechanism for deciding when to retransmit * Modified congestion window sizing mechanism * Modified congestion detection and avoidance mechanism VII. SIMULATIONS In this section we are going to simulate small network using different TCP versions in order to evaluate their performance and see their actual difference between them. The simulation will be carried out between two fast network nodes connected via a slow link. The diagram below shows all the link bandwidth capacity and delays. Source Destination (0)- (1) - (2) - (3) 10Mbps 6ms 1Mbps 10ms 10Mbps 6ms From the diagram above packets was sent from network node 0 to network node 3 via node 1 then node 3 and finally arriving at destination node 3. Tiny acknowledgement packets then were sent back to receiver via the reverse route. Expected bottleneck was form between node 1 and node 2 due to different link speed between node 0 and node 3. The queue discipline used in our simulation was DropTail with the maximum queue size of 8 packets. The simulation also was set to support one way traffic from node 0 to node 3 therefore tiny acknowledgments packets were expected not to be discarded on their way back to sender from receiver. This simulation is intended to support evaluation of TCP traffic control mechanisms such as slow start, congestion avoidance fast retransmit and fast recovery. The simulation was run for 10.5 seconds and the following value was recorded every 1 second and observed throughput in (Mbps) and window size as a function of time. After finish running this simulation gnu-p lot tool was used to display the following results. TCP Tahoe Results From the two diagrams above we see from 0 seconds to 2 seconds TCP Tahoe was in slow start mode of operation, when it got to about 0.4 seconds we see the first packet loss occurs and immediately TCP Tahoe reset its congestion window size to half of its current size (see 3). We also observe the throughput reduced to almost zero when packet loss occurs this is because when packet loss happens TCP Tahoe is required to stop sending packets and go back to slow start phase before start sending packets again hence no transmission. We also see from 2 second onwards TCP Tahoe enters congestion avoidance mode of operation, whereby TCP Tahoe allow the congestion window size to increase exponentially until packet loss occur then go back to slow start mode to start transmission again. TCP Reno Results In 4 and 5 we see TCP Reno enters congestion avoidance mode of operation with fast retransmission from 2 to 10 seconds but at 0.4 second we TCP Reno enters fast retransmission then at 0.6 second come out of fast retransmission and go back to slow start mode of operation which is the same as TCP Tahoe this is because TCP Reno cannot detects more than two one packet loss in a single data window. We also see every time packets loss happens throughput is reduced to almost zero, this is because of the same reason explained above. TCP NewReno Results 6 and 7 show that TCP NewReno enters fast retransmission/ fast recovery mode due to packets loss which occurs around 0.4 seconds and never come out of this mode of operation because it was able to detect multiple packets loss in single data window unlike TCP Reno. But from 2 seconds onwards TCP NewReno behaves the same as in TCP Reno. TCP Sack Results 8 and 9 also show TCP Sack is preventing the communication path from not going empty after packets loss happens at 0.4 seconds by entering fast retransmission mode of operation and not come out until all packets sent in a single data window acknowledge. TCP Sack works the same as TCP NewReno but use selective acknowledgment to retransmit the loss packets. TCP Vegas Results In 10 and 11 we see TCP Vegas manage to achieve the network high bandwidth this is because TCP Vegas uses sophisticated traffic control algorithms to anticipate the congestion of the link rather than reacting to congestion. We also see at 0.1 second TCP Vegas enters slow start mode of operation and packet loss start occurring around 0.6 immediately after packet loss detected TCP Vegas set its window size to 8 packets and at the same time reduce its throughput to 0.5Mbps. From 1 to 10 seconds we see TCP Vegas maintain steady congestion window size of 8 packets and the throughput was increased to 1Mbps which was the maximum throughput set for our simulation. VIII. CONCLUSION In this paper we present an overview of different TCP versions, discuss different traffic control algorithms used by different TCP versions and discuss in general what TCP is. We see these TCP versions perform different depending to network environments. We see TCP Tahoe and TCP Reno perform better when network environments are not of high loss packets while TCP Sack was slight perform better than TCP Tahoe and TCP Reno. We also see TCP Vegas was one of the best TCP Version compare to all versions discussed in this paper. In our simulation we see TCP Vegas was able to reach the maximum throughput and maintain this state for more than 8 seconds of our simulation, this is because TCP Vegas is much more robust over loss packets network and it can detect and retransmit loss packets much earlier than others. The work presented in this paper provides a means of compare and evaluate different transmission control protocol versions.

Definitions on the concept of nationalism

Definitions on the concept of nationalism Nationalism is a concept that is not easily defined. There are numerous definitions and forms of what is nationalism, and many of these definitions even overlap. However, there is no one definition that is more adequate than another. Keeping in mind that these definitions are constantly evolving, with thorough analysis and the juxtaposition of arguments set out by eight prominent scholars, a clearer definition of nationalism can be attained. To begin with, the most well know definition today is from Professor Anthony Smith. He states that nationalism is simply an ideological movement for attaining and maintaining autonomy, unity and identity for a population which some of its members deem to constitute an actual or potential nation (Smith, 2001). In this definition, Smith reveals what he believes the three main goals of nationalism are: autonomy, national unity, and national identity. Even Smiths profound definition has not been available for very long considering he was born in 1933. Although there is much argument on the definition of nationalism, Smith agrees that there is one main point of agreement and that is that the term nationalism is a modern phenomenon (Smith, 2001). Civic nationalism is basically defined as a group of people which have a certain loyalty to civic rights or laws and pledge to abide by these laws. Ethnic nationalism is basically a group that possesses a common culture, language, land, etc. It is more specific in terms of who can be in it (McGregor, 2010). Smith writes that every nationalism contains civic and ethnic elements in varying degrees and different forms. Sometimes civic and territorial elements predominate; at other times it is the ethnic and vernacular components that are emphasized (Smith, 2001). Smiths most popular argument features civic and ethnic types of nationalism as opposed to eastern and western types. Even more specifically, Smith makes the distinction between both civic and ethnic nationalisms. He also believes that Many modern nations are formed around pre-existing, and often pre-modern, ethnic cores (Smith, 2001). Smith is claiming that nations had pre-existing-origins prior to their new origins of their new nation. One of the most important arguments by critics is that the civic and ethnic viewpoint of nationalism collapses too much on the ethnic category (Shulman, 2002). Smiths definition seems to be the foundation for nationalism, although he ce rtainly was not the first to attempt to define it. Other scholars go in to more detail on certain elements of the definition, but most relate back to Smiths original definition. On the contrary to Anthony Smiths definition of nationalism pertaining to the civic and ethnic type, Hans Kohn has argued that the two main types of nationalism are eastern and western. His definition states, Nationalism is a state of mind, in which the supreme loyalty of the individual is felt to be due to the nation-state (Kohn, 1965). Kohns argument includes both eastern and western types of nationalism which refer to Eastern and Western Europe. Eastern nationalism conceived the nation as an organic community, united by culture, language and descent (McGregor 2010). This particular idea could possibly be related to Smiths ethnic type of nationalism. Western nationalism conceived the nation as a political and civic community, held together by voluntary adherence to democratic norms (McGregor 2010). Again, western nationalism could be perceived as a civic type of nationalism. This can be recognized as two similar classifications on two unfamiliar grounds. Kohn believes that national ism relates directly with eastern and western Europe and that it is also where the state of mind of nationalism originated. The main criticism of Kohns classification of nationalism is him being over simplistic. He certainly does not go into as much detail as Smith on the definition. He also relates only towards Europe which is why he is being identified as over simplistic. Next, Carlton J. H. Hayes definition of nationalism states, Loyalty and attachment to the interior of the group (namely the nation and homeland) are the basis of nationalism (Hayes, 1926). In this definition, a common cultural background and a common cultural group are considered the main factors in forming a nation (Naqvi, Ali). That remains true with most of the definitions of nationalism. Hayes definition of nationalism seems to be more specific to the ethnic ties toward nationalism. In other words, Hayes is saying that land, language, and blood are the basis of nationalism. He is saying that nation is something to be proud of (Naqvi, Ali). Hayes also believes that these ethnic qualities are the most important; even religion does not compare.   It is attachment to nationality that gives direction to ones individual and social postures, not attachment to religion and ideology. A human being takes pride in his national achievements and feels dependent on its cultural heritage, not on the history of religion and his faith (Hayes, 1926). This quote further proves Hayess view on nationalism and how it relates to ones culture and past, and specifically not related to religion at all. The reason Hayess definition is unique from others, is his emphasis on the fact that religion is not a factor in forming a nation. To further specify Hayess definition on nationalism he says, What distinguishes one human being from another are not their beliefs, but their birth-place, homeland, language and race. Those who are within the four walls of the homeland and nation, belong to it, and those who are outside it, are aliens. It is on the basis of these factors that the people have a feeling of sharing a single destiny and a common past. (Hayes, 1926). This quote goes hand in hand with Hayess definition of nationalism and just further explains it. According to Hayes, nationalism does not exist without that ethnic background. Furthermore, according to scholar Benedict Anderson, nationalism is, a new emerging nation imagines itself to be antique (Anderson, 2003). This is similar to how Anthony Smith and Carlton Hayes defined nationalism. It is mostly like Smiths ethnic nationalism, which focuses more on the origin of the nation. Anderson focuses more on modern Nationalism and suggests that it forms its attachment through language, especially through literature (Anderson, 2003). Of particular importance to Andersons theory is his stress on the role of printed literature (Anderson, 2003). In Andersons mind, the development of nationalism is linked with printed literature and the growth of these printed works. People were able to read about nationalism in a common dialect and that caused nationalism to mature (Anderson, 2003). Andersons definition of nationalism and nation differ greatly from other scholars. He defines nation as an imagined political community (Anderson 2003). He believes this because the nat ion is always conceived as a deep, horizontal comradeship. Ultimately it is this fraternity that makes it possible, over the past two centuries, for so many millions of people, not so much to kill, as willingly to die for such limited imaginings (Anderon, 2003). Not only is Andersons theory distinctive because of the printed literature theory, but also because it is the imagined political community. Another prominent Nationalist researcher, Ernest Gellner states that, nationalism is primarily a political principle that holds that the political and the national unit should be congruent (Gellner, 1983). Gellner was once a teacher of Anthony Smith. Although most scholars would agree that nationalism appeared after the French Revolution, Gellner further argues that nationalism became a sociological necessity in the modern world (Gellner, 1983). His argument is similar to the uniqueness of Benedict Andersons printed literature theory, but Gellner focuses more on the industrialization of work and cultural modernization to explain how nationalism expanded (Zeulow, 1999). Gellner believes that states only exist where there is division of labour, therefore the state comes before nationalism (Gellner, 1983). Like other scholars, Gellner believes that nationalism is a political force. Gellner also stresses the congruency of nation and politics. He does not believe one can occur without the other one. There are many criticisms to Ernest Gellners theory, including Anthony Smith saying, It misreads the relationship between nationalism and industrialization (Smith 1998). Not all of the critics view Gellners theory as a misread. Most agree that he is the father of nationalism studies and most say that his nationalism work was brilliant (University of Wales Press). One can usually relate their definition of nationalism with Ernest Gellner or Anthony Smith. Gellner stresses the importance of the political side, while Smith puts the importance on cultural. Neither are right or wrong, just a difference of opinion. Historian John Breuilly defends a more modern theory of nationalism, similar to Benedict Andersons. In reference to nationalism, he concludes, The rise of the modern state system provides the institutional context within which an ideology of nationalism is necessary (Breuilly 1985). Breuilly argues that the process of state modernization provides an important factor in understanding historical signs of nationalism (Cormier, 2001). Breuilly argues that nationalism does not have much to do with ethnicity or ethnic background, but rather more to do with political motivation. Breuilly is not the first scholar who believed that ethnic background had nothing to do with nationalism. In fact, Breuillys definition relates well to Gellners in the sense that they both argue in favor of political motivation. Nationalists are seen to create their own ideology out of their own subjective sense of national culture. (Breuilly, 1982). This particular quote is quite similar to Andersons imagined polit ical community theory in that Breuilly does not support the ethnic side of nationalism nearly as much as others nationalists. Breuilly criticizes most scholars due to the fact that they believe in national culture because he believes that there is no such thing. He believes that the political component of nationalism is by far the most important. Breuilly indicates in his definition the importance of the state system; hence the political force necessary for nationalism to occur. Next, Michael Hechter defines nationalism as a, collective action designed to render the boundaries of the nation congruent with those of its governance unit (Hechter, 2000). He further explains, Nation and governance can be made congruent by enacting exclusive policies that limit full membership in the polity to individuals from on one more favoured nations (Hechter, 2000). Hechter stresses the importance of the correspondence of the government and the boundaries of the nation; much like Breuilly in the sense that both of them indicate that nationalism requires congruency for it to take place. In Hechters book, Containing Nationalism, he expresses his belief that the reason nationalism occurs is because of self-determination. Hechter further explains his definition and clarifies that there are two different types of nationalism. The first one is of the ideology of freedom and he gives the example of the French Revolution. The second form is xenophobic or even goes as far as genocide (Hechter). This explains where the different views of nationalism come in; civic versus ethnic or eastern versus western. Furthermore, Hechter defines the two different types of nationalism to even more specific forms of nationalism that go beyond his original definition. These definitions include: state-building nationalism, peripheral nationalism, irredentist nationalism, and unification nationalism (Hechter, 2000). Hechter doesnt argue that there are two definitions of nationalism like other scholars do, but he concludes that nationalism is specific to the means of each and every situation. In Peter Alters definition of Nationalism, he states, Nationalism is a political force which has been more important in shaping the history of Europe and the world over the last two centuries than the ideas of freedom and parliamentary democracy or, let alone, of communism (Alter, 1994). His argument is similar to John Breuilly in the sense that he agrees that there is a strong emphasis on nationalism being a political force. Alter is saying that it has everything to do with being a political movement instead of the idea of freedom. In reference to nationalism, Alter states, It can be associated with forces striving for political, social, economic and cultural emancipation, as well as with those whose goal oppression (Alter, 1994). His outlook on nationalism seems much broader than other scholars. This particular reference virtually sums up many scholars definitions together. Alter does not seem to have a specific argument on nationalism, as in civic vs. ethnic or western vs. eastern but just an acceptance that nationalism could be based on all of these arguments. Again, Alter says, It can mean emancipation, and it can mean oppressionà ¢Ã¢â€š ¬Ã‚ ¦ dangers as well as opportunities (Alter, 1994). There is no precise argument when he tries to define nationalism even though he does have the idea that nationalism is directly related to a political force. Alter also states that nationalism was important to shaping Europe, however most scholars agree with that statement to begin with. Most modern scholars would relate to Alters style of defining nationalism. In conclusion, the definition of nationalism is not easily defined and scholars that have tried to define it differ, in some amount of detail, from each other. Each scholar seems to have his own uniqueness and input to the definition, however, these definitions tend to pertain to one certain area of nationalism. According to the eight previous scholars, there are a myriad of styles of nationalism including: political, cultural, ethnic, civic, eastern, and western. Many aspirations are desired because of nationalism, including establishment of homeland, separation, expansion, etc. Although the definition of nationalism is essentially particularistic, scholars have been able to identify a few common ideologies. Some common ground includes; most scholars agree that nationalism started after the French Revolution. They also agree that nationalism occurs because of a desire for national independence. Scholars are always doing research and finding new things which will result in new defini tions. Most of the most protrusive definitions of nationalism have come about in the last fifty or so years, so no telling what scholars might come up with in future years.

Tennessee Williams A Streetcar Named Desire :: Williams Street Car Streetcar Essays

Tennessee Williams' "A Streetcar Named Desire" The play 'A Street Car Named Desire' by Tennessee Williams has many characters with different personalities. One character that seems to play an important part in this play is Stanley. The ruff and hardened blunt husband of Stella, this is shown to us in the first two scenes introduces this character to the audience, and shows his attitude towards the environment that he lives in. Through out the following I shall be discussing about how Tennessee Williams introduces Stanley to the audience and this helps us learn about him. At the beginning of the first scene the audience meets Stanley, Tennessee presents Stanly and a friend (Mitch) as 'They are about twenty-eight or thirty years old roughly dressed in blue denim work clothes'. This gives us an immediate impression of a classic American working class guy, that doesn't have an impressive education record. Tennessee shows another example that 'Stanley' is of a low status, when he addresses 'Stella' as 'Baby!'. This shows the audience that Stanley is not being rude, but it is just the way in which he has developed his vocabulary in a slang street manor. It also shows the audience that he shows little respect even with the use of this slang terminology. Another aspect that the audience will learn about Stanley is that he is adored by his wife 'Stella' this is shown when she asks Stanley if she can come and watch him play bowling. This would not be normal behavior of average women in the time since, the time when the play is set bowling was to be a manly sport. However one is left to wonder whether if Stanley simply draws women to him in this idealistic way. This extravagant entrance for the character Stanley , makes the audience feel that he has an important influence in the play. Stanley is portrayed as a womanizer, and he carries on with this practice even after he knows that his wife is pregnant. It's bad enough that he is carrying on with this when he has a wife. The audience is made to feel that Stella knows of his habits of purposely attracting women and flirting ass it has to have been the same way he got involved with Stella. This could be a suggestion of why Stella asked him if she could join him and watch at the bowling alley. Stanley is portrayed as the man you love to hate, he is thee man that men want to be and the ruff end qualities women drawn to. Even though he hasn't been brought in the rich heritage the Stella and her sister

The Sedition Act of 1798 :: history

a day in my life :: essays research papers

The Day My Life Changed I stepped through the door to my grandmother and grandfather's home without even aknock. My grandpa looked up from the television he was watching, from his cozy comer chair.He had a head of snowy white hair gleaming in the room. Over his broad body, hung a navy bluedress shirt and a fuzzy cardigan sweater. He wore slacks, held up awkwardly by a belt, allowinghis small potbelly to hang over it. His face showed the years of worry and stress, and his whitebushy eyebrows and growing second chin showed his old age. His smile greeted me. As I drewclose to him, his aging arms reached out and wrapped around my body and pulled me into a warmloving hug. As he released me from the hug, I said, "Grandpa, I have some news I want you tohear" as I plopped down in the chair beside him. "I wanted to let you know that I am getting married," I told him.The room was left in a dead silence, frozen for a brief period of time, as we recovered from the intensity of the news I had brought him. Reaching for the remote to turn off the television, my grandfather looked at me. Before he could say a word, the excitement of an unseen grandmother came from the kitchen.Both our eyes looked toward the cheerful light and the sounds of my grandmother's excitemen tAs the excitement faded away, his eyes turned toward mine. Awaiting his comments, my eyes were open wide. Excitement had filled my body, because of the news I had just brought him."Wonderful, go ahead and tell me all about it," he exclaimed.Well, I woke up this morning just as I always do, but this time it was to the ringing of the phone. I reached for the phone and said "Hello," and on the other end was my boyfriend. He said he needed to see me as soon as possible, so I said "OK," and went to meet him. When I arrived at his house, he met me at the door and asked me to come in and have a seat on the couch, I was a little worried at this time. I sit down on the couch and he kneeled down in front of me on one knee, I just looked at him knowing now, what he was up to. This is what he said, "I know wehave been through a lot here lately, but I also kn ow that we can go through a lot more as long as

On the Necessity of Rationalism

In the process of considering the various means of justification, a relativistic conception of reality assumes that the truth and hence the validity of a statement may only be assessed in relation to the perspective of the discipline which holds a particular belief. In this sense, truth is dependent upon the internal coherence of beliefs within a system of thought. In his The Last Word, Nagel claims that such is not the case. He argues that the truth and hence the validity of statements are dependent upon an unqualified notion of reason.He claims that the truth of a statement is independent upon any particular perspective. If such is the case, it follows that the truth of any statement is independent from the schema [truth schema] presented by any system of thought. In relation to scientific claims, it thereby follows that the truth of scientific claims ought to be assessed through the unqualified notion of reason as opposed to merely their internal coherence within the scientific co nception of reality [scientific framework].The aforementioned argument is based upon the critique of the intrinsic limits to subjectivist doubt since challenges to the independent validity of reason must themselves assume the independent validity of reason. Any explanation of reason deriving from outside the mind can itself be explained only from inside the mind, as having its own independent validity. In the case of scientific knowledge, he argues that it is mistaken to assume that the scientific discipline has freed itself from the limits of the Cartesian problem through the replacement of judgments about rules of practice from objective judgments.Nagel argues that if science will continually adhere to a subjectivistic and hence relativistic framework, the discipline will fail to provide an objective account of reality. He claims, â€Å"the general aim of such reasoning [scientific reasoning] is to make sense of the world in which we find ourselves and how it appears to us and ot hers† (81). If such is the case, it is necessary to conceive of the conception of the world which is not based upon an a priori conception of reality dependent upon a preconceived and limited conception of the word. According to Nagel, such an account is not provided by science.The reasons for this lies in the subjectivism of science (Nagel 84). Subjectivism within science [scientific methods] is apparent if one considers that the scientific â€Å"demand for order cannot itself be rationally justified nor does it correspond to a self-evident necessity† (Nagel 84). He notes that scientific subjectivism can only end if it adheres to rational means of knowledge acquisition. It is only through the defense of rationalism that an objectivist account of evidence is possible.Nagel further argues that the appeal of subjectivism arises out of a certain reductionist impulse in modern explanation as this reductionist impulse enables the explanation of things to hinge on their reduc tion to local and finite terms thereby ensuring subjectivist conclusions. Although this enables the assurance against rationalist explanations that refuse to make reason into something irrational or that conceive of reason as a capacity for grasping the universal and infinite principle, the reductionist explanation is in itself dependent on an irreducibly nonlocal and objective understanding of reason. Nagel argues that doubt about reason presupposes reason’s independent validity hence reason’s independent validity cannot be coherently doubted.He rightly argues that to object to reason on the grounds we cannot strictly explain it in naturalistic terms is to misunderstand the irreducible nature of the concept since reason cannot be so explained without losing its meaning or validity and that, as such, it is justified in a different way, by showing it to be necessary to intelligible thought and action. Science thereby must opt for a rationalistic as opposed to a subjecti vistic account of reality for it to maintain its value as a discipline.Work CitedNagel, Thomas. The Last Word. New York: Oxford University Press, 1997.Essay Number TwoEdmund Gettier’s Counterargument Against thePlatonic Tripartite Account of Propositional KnowledgeThe Platonic tripartite definition of propositional and fallibilist knowledge found in the last section of the Theaetetus states that knowledge of P occurs when an epistemic agent S knows that P if and only if (1) P is true, (2) S believes that P, and (3) S is justified in believing that P (90). A well-known opposition to such an account of propositional knowledge questions the sufficiency of the aforementioned conditions.It is argued that although the aforementioned conditions are necessary in the definition of propositional knowledge such conditions are insufficient due to their failure to ensure S against conditions wherein knowledge of P occurs as a result of mere epistemic luck (Gettier 123). This critique is b est known as the Gettier type counter examples towards the tripartite definition of propositional knowledge mentioned above.A logical problem is posited by the Gettier type counter examples. This logical problem is evident in the lack of successful coordination between the truth of P and the reasons that justify S in holding P. Floridi notes that Gettier type counter examples arise â€Å"because the truth and the justification of P happen to be not only independent but also opaquely unrelated that they happen to fail to converge or agree on the same propositional content P†¦without S realizing it† (64). In order to understand this, it is important to lay down the main assumptions of Gettier’s counter argument that seeks to explicate the aforementioned logical problem.Gettier’s argument against the tripartite account of propositional knowledge, which involves the conception of knowledge as justified true belief arose as a result of the following claim: knowl edge [propositional knowledge] does not merely involve justified true belief. Such a claim is based upon the following assumptions. First, there are instances wherein the warrant is not a sufficient condition for a belief in P. This is evident if one considers that instances of belief and knowledge of P are in some respects epistemically different [other than in terms of truth] from belief of P without knowledge of P. Second, there are instances wherein warrant is fallible.This is due to the insufficiency of truth and justification as warrants for knowledge. The evidence of such, according to Gettier is apparent if one considers that it is possible for P to be false even if S believes that P possesses epistemically significant properties such that whenever a belief possesses such properties and is true the belief may thereby qualify as knowledge. Lastly, there is the closure of knowledge under obvious and known entailments. The last assumption argues that if S is justified in believ ing P and a deductively valid inference is drawn from P to another belief Q then S is justified in believing Q. This is a result of the entailment of Q from P.From what was stated above, it is possible to present the usual form of Gettier’s attack against the tripartite account of knowledge. Gettier’s counter argument is based upon the critique of warrant, fallibility, and closure. Note that combination of the three claims mentioned above leads to a contradiction. From what was mentioned above it follows that it is possible to believe in an obvious deductive consequence of P, which is Q, while in the process retaining the epistemically significant properties of the belief in P.If such is the case, it is possible to have a justified true belief of any property which has led S to have a belief in Q or any other type of belief which has Q’s epistemic characteristics. Note that this contradicts the assumed necessity that P and Q differ from each other since one qual ifies as knowledge [S believes and has knowledge of P] whereas Q merely qualifies as a belief [S believes but does not have knowledge of Q].Works CitedFloridi, L. â€Å"On the Logical Unsolvability of the Gettier Problem.† Synthese 142(2004): 61-79.Gettier, E. â€Å"Is Justified True Belief Knowledge?† Analysis 23(1963): 121-23.Plato.

Science Has Made Man’s Life Quite Comfortable

Science has changed the face of the world. It has, of course, given many things that benefit man. But the evils that it has showered on man wash away the advantages. It has made man depend on machines, calculators and computers. A day may come when his physical and mental faculties may grow so weak that he may not be able to lift a bag or solve a simple equation. In the field of health services, it has given us life-saving drugs. But it has also given drugs like smack and heroin. Nuclear energy created by science has been much praised but the blast in Russia has exploded the myth.Atom bombs created by scientists were thrown on Hiroshima and Nagasaki decades ago. The painful memory still lingers and millions of people are still ill. I apparently support science. Science has made all the things possible. REALLY†¦. without science we cannot imagine our lives. humans might have extincted long back if science had not been improved. so,i think it ‘s not a bane for the society. T here is a misconception about science ,people think that it is the science which is responsible for the explosions as well as destruction.But I think it is human brain which caused all this destruction. PEOPLE fought and had lost their lives before the improvement of science also. so, it is definetly a boon for the society The greatest harm science has done is to the faith of man. God has become a nonentity. In the modern jungle of mental activities where would a desperate man go? Having lost faith, his intellectual activities lead him to suicide. A number of scientists meet this fate every year in India. By This we can conclude that Science has more Boons than Banes.

Continental Airlines: Flying High with Its Data Warehouse

The airline industry is a competitive market in which some airlines are profitable while others are not. During the late 1990s, most airlines were lucrative because fuel costs were relatively low and travel was at an all time high amongst flyers. Recently, the airline industry has taken a severe hit due to the increased rate of oil, the 9/11 attacks, and anti-traffic control system to name a few. However, Continental Airlines remains one of the largest airlines in the United States holding its rank in fourth place amongst other airline companies.Initially, Continental Airlines was not highly regarded because of its information technology (IT) and organizational culture. Unlike other airline companies, Continental Airlines has taken extreme measures by adopting new strategies to overhaul its IT department altogether. The information systems Continental had in place was old and outdated because it did not provide information of its most valuable customers. The Transaction Processing Fa cility (TPF) was the old IBM mainframe system Continental’s IT team had during the late 1990s. The system was not designed for customer service.In order for Continental to accomplish its goals, the IT team realized the need to replace its old mainframe. The IT team determined it needed to integrate into one system by consolidating the airline’s disparate customer management relationship (CRM) systems. As a result, Continental joined forces with Teradata to build an enterprise data warehouse comprised of 25 enterprise systems. The warehouses consist of â€Å"schedules, reservations, customer profiles and demographics, airline maintenance records and schedules, employee and crew payroll, and customer care† (Rainer & Turban, 2008, p.132).Additionally, executives of Continental Airlines were able to develop the Customer Value Metric (CVM), which enables them to determine how much money customers spend with its airlines and the costs of flying the customer as well. T he data warehouse is a repository of historical data that assist with business operations to include â€Å"data mining, decision support, and querying applications† (Rainer & Turban, 2008, p. 117). Many components make up the data warehouse such as business dimensions in which data is organized by customers, vendors, product, price level, and region.The data in various databases are encoded differently and kept historically for many years. Once data enters the warehouse it is not updated. Databases use online transaction processing (OLTP), in which business transactions are processed online as they occur. Typically, data warehouses are designed to support decision makers by using online analytical processing (OLAP) for the analysis of mass data by end users. Data is stored in a multidimensional structure as well. All data in the data warehouse comes from Continental Airlines operational databases which can be relational databases as well.These components enable users access t o corporate data for analyzing. Special software such as extract, transform, and load (ETL) are used to process data to later store in a data warehouse. However, only a summary of data is transferred to the warehouse. This data is organized in a form that is easy for end users when accessing. The reason why Continental Airlines remains successful is due to their strategies for improving and enhancing quality customer service with many functions implemented by their IT team.Continental Airlines main focus is increasing customer rewards and incentives of frequent flyers that are loyal customers, while gaining new customers that are profitable too. Continental Airlines contributes its success to the quality customer service and customer satisfaction it provides by expanding its routes and serving meals on every flight. Some airline companies have gone bankrupt while others simply choose not to improve their quality of customer service. As a result, customers have become irritated due t o the lack of reasonable rates, delays, and strict rules of other airline companies.In closing, information technology is essential for airline companies. Some airline companies may choose to stick with basic airline technology. However, an airline company can enhance its level of customer service and profitability based on the type of changes it needs to make. Executives of an airline company can look to its IT department to strategize ways to utilize information systems that best fits its goals, business practices, mission statement, customer service, and customer satisfaction.
