List and define the steps in the new-product development process Essay

By its very nature, marketing requires companies and organisations to develop new ideas and make adjustments to their marketing efforts. New concepts, designs and products are essential for responding to the ever-changing demands of the target market/s, and are crucial for maintaining customer satisfaction, which ultimately leads to increased revenues and profits for the firm. New-product development dictates the company’s future in the market. Every person’s wants are unlimited; however, a person’s needs are narrowed to a limited amount. A product is something that can satisfy people’s wants and needs. It is one of the variables in the marketing mix (one of the ‘7P’s’). A product can be considered as the most important item in the marketing mix, since ultimately the marketing mix revolves around the Product. It can be offered to the market in the form of goods, services, ideas, events etc, The following are the classification of goods . This is crucial information for marketers as market segmentation exercises are carried out within the company in order to target certain groups of customers with specific use-related and use-situated needs. Below are four main classifications of goods; Convenience Goods – these are those goods which are bought on a daily basis, products of this type are usually considered as needs. These are goods such as milk, bread, detergents etc†¦ Shopping Goods – these are mostly semi-durable goods which are purchased less frequently then convenience goods. These cost more than convenience goods, thus people tend to choose products over others in a process of choosing the preferred alternative. Clothes and white goods are ordinary examples Specialty Goods – these are goods which are bought infrequently. If a person decides to purchase a specialty good, one will take time on choosing the good, since these goods are much more costly than the two previously mentioned. When this type of good is bought after sales service is usually provided. Example of this type of goods includes property & motor vehicles & a Luxury holiday in a high standard hotel. Impulse Goods – these goods are not actively searched by customers when one is making a purchase. However, a last minute impulse makes a customer purchase goods. Impulse goods usually occur in supermarkets or department stores. Idea Markets – The creation and evaluation of new product ideas are important procedures in the new product development process. Idea markets help companies by using virtual stocks to represent product ideas, introducing a virtual marketplace for these ideas to interact and use the forces of the market to generate certain stock prices that will indicate whether a product idea could be successful or not. Thus, the concept of idea markets has been considered as one of the leading methods of creating and evaluating new product ideas. Both the creation and evaluation of ideas require certain things such as creativity and long-range forecasting abilities, but they also suffer from a great deal of uncertainty (Creative Trainer: 2007) . The following three factors show why idea markets have been proposed as the new method of creating and evaluating product idea, mainly because they positively influence the quality of new product ideas: 1.Large Number of Ideas and Idea Creators It is essential that the quality of product ideas is given importance, as this determines the commercial success of the product. However, it is not quite that easy to determine the people that should be involved in the product creation as well as the main characteristics of the product idea. A wide pool of ideas might give rise to some unexpectedly good concepts that aren’t in demand at the moment but might be the breakthrough product idea sometime in the future. To broaden the scope of the search of the next best product idea, companies consult with several diverse and external sources such as employees, suppliers and researchers . Due to its uncertainty, participants of idea creation should come up with a substantial amount of product ideas. It follows that a high quantity of idea correlates to a high quality of positive product ideas, thus, creativity is an important element that shouldn’t be under-valued or diminished. Activities of idea creation, such as brainstorm ing, should promote individual creativity. Companies nowadays are creating and innovation friendly and relaxed office environment so as to enhance the innovative performance and creative thinking. Innovation leads to the development of new ideas in order to sustain present customer needs within the market. This can be achieved with the support of many different processes that help the company to expand into something different instead of building on something that they already have. One of  the many methods of innovation is symbiotic ideas, where multiple ideas are combined, adding the pros of all ideas without incurring all the cons, to make a better general idea. The second method, targeted innovation, is highly used in large scale companies and deals with the idea of a direct path that leads to a result that is not only known from the beginning of the process but also expected. Finally, the revolutionary idea is one that portrays a whole new different perspective which sets it apart from traditional school of thought. An example of this ideology is Marxism . 2.Group decisions instead of individual decisions When companies engage in finding a new product to develop, ideas about a new product can be established from a group of idea creators and by means of a discussion and exchange of opinions. This will result in high quality ideas that can prove useful to the company when deciding what product to produce. Ideas formed through group discussion can be generated through several activities such as idea competitions and ideation games, this will cause the participants to widen their thoughts and observe other participants ideas before acting. It is also ideal that the persons that will evaluate the product work as a group, this will improve the quality of their evaluations due to the fact that one person might see something that the other person missed and even one can also criticise the other until a compromise is found. Interactive and iterative evaluation techniques allow participants to widen their knowledge and continuously learn more and more, thereby improving the quality of the decis ion taken . 3.Combining the creation of ideas with their evaluation Most of the ideas generated will support either the creation of the new product or the evaluation of the new product. This will be beneficial due to the fact that participants can focus more towards the creation process. The problem that arises may be the fact that idea creators will not receive immediate feedback regarding their ideas, this may result in the ideas being vague or even out of the range intended for them to be in. The ideas generated are usually split into three main criteria; mainly being in respect of their quality, commercial success and new to the world. The  criteria usually provide skewed results and only few of the ideas turn out to be of a high quality. Another problem that may arise is the fact that companies review a large number of ideas from which only a moderate portion are processed for further development. Participants who have knowledge of the product and are able to create new product ideas are usually even capable of evaluating the product ideas generated. Combing these participants’ together results in a positive and successful evaluation of new product ideas. Levels of product – When searching for new product ideas one must also keep in mind that the product is made up of three components; Core product, Actual product and Augmented product. The core product is the part of the product that makes it beneficial to the consumer and answers the question â€Å"What is the buyer really buying?† The actual product is the tangible, physical product. The Augmented product on the other hand refers to the non-physical part of the product, the added value one gets from purchasing the product, such as customer service, after sales support, delivery, installation etc . Product Characteristics – When finding and developing new product ideas one should incorporate and think about the product attributes, branding, packaging and labelling. One must consider the quality level and quality consistency of the product. This refers to how the product is perceived and how the product will be expected to perform during its life. One should also think about the features that are expected to flow from the product and the characteristics of the product that contribute to the benefits it offers. Substantial thought should also be given regarding the design of the product. Another important aspect of the product that requires rational, especially in new companies, is the brand of the product. This usually incorporates a name to the product, sign, symbol or a combination of the above mentioned. Branding provides a unique attribute to the product therefore it should be attractive and easy to recognise and remember. Many people buy a product solely on the strength of the brand. The packaging o f the product is yet another important factor. It includes the wrapper or container for the product. The packaging should  protect the product and ensure it reaches the buyer in the condition it is intended to and also incorporated with the packaging should be a set of instructions and safety labels on how to handle the product . Managing the New-Product Development Process – The need for new product development may arise due to other external forces such as competition from rival firms. Innovation and new ideas are forced into play within the market as firms compete for a bigger customer base and market share. In addition, new product development may occur due to the actual product becoming obsolete and/or inadequate for present customer’s needs. There are many other reasons why new product development is vital. These may include: -Innovative/unique products earn higher profits than older products. -New products can help reposition the company in customer’s minds and shift their perception about the new product/s -Some firms market seasonal products that reap their highest sales during a certain time of the year (for example, ice-cream vendors). Expanding the firm’s product mix into new areas may help offset these fluctuations. The development method may take two forms. The company can develop new products in its own laboratories or it may contract independent researchers or firms to develop specific original products. Furthermore, we can identify six categories of new products ; 1.New-to-the-world products. (Such as the first Microsoft tablets were in 2002) 2.New product lines (new products that allow a company to enter an established market) 3.Additions to existing product lines (New product that supplement existing products, eg new flavours, sizes etc) 4.Improvements and revisions of existing products 5.Repositioning ( existing products that are targeted to new markets) 6.Cost Reductions Before we get to the new product development process there are few decisions a company must take. It must decide on how to segment the market, which will be the target customers, identify their needs and determine its market positioning for the new product. Nowadays, companies use customer-driven engineering, which is the process whereby the design of the final (new) product incorporates its target customer’s preferences. These preferences are determined through market research methods, such as the collection of  primary and secondary data. Lastly, the company must set a budget for the new product. Management must decide what proportion of investment will be necessary for research and development activities as well as the gathering of market intelligence and market research. Once this is set, the New-Product Development process may begin. There are 8 steps in the New-Product Development process as defined by kotler. 1. Idea Generation The process starts with the hunt for new ideas. The key to successful ideas, is understanding customer’s present or unmet needs in the market. For example , Procter &Gamble’s efforts in 1985 to create a bold new advertising campaign for Folgers to catapult it into market leadership began by watching consumers make coffee and by listening to their descriptions of their process of waking up in the morning. From these efforts came the insight that people actually wake up to the smell of coffee before they get to the taste And, thus was born â€Å"The best part of waking up†¦Ã¢â‚¬  The insight worked so well, it’s still guiding the marketing campaign today – twenty years later. Ideas for new products can be obtained from customers, the company’s R&D department, focus groups, competitors, salespersons, employees, trade shows and events etc†¦ 2. Idea Screening The second stage is to get rid of unsound ideas prior to dedicating resources to them. The ‘screeners’ must ask at least three questions : Will the customer in the target market benefit from the product? Is it technically feasible to manufacture the product?, Will the product be profitable when manufactured and delivered to the customer at the target price? An important consideration must be made in screening ideas. This stage is crucial for companies as they must avoid two types of errors ; A Drop-error – which occurs when a company dismisses a good concept for the new product A Go- error – occurs when a company goes forward with a poor idea up until the last new-product development stage, commercialization. This can prove to be extremely costly is the idea is not received well in the market. A recent example of this is when in 2010, GAP launched a new logo in an attempt to be more modern This only lasted two days as GAP received an unbelievable criticism from the public, who expressed felt that GAP was changing their image for the worse. 3. Concept Development and Testing Having identified the right product idea, a product concept must follow – this is an elaborated version of the screened idea. The notion here is that a product idea can be turned into numerous product concepts. These concepts are developed with marketing and engineering specifics. Before the next step, the product concept must be tested. This follows by ‘giving’ the concept and all information about the product to a group of target customers and obtaining feedback and responses from them. The reactions obtained would indicate whether the customers in the target market would welcome concept or not. 4. Marketing Strategy development In this stage, the new product formation will begin as a result of the conclusions derived from the concept development and testing stage. A strategy-plan would be drawn up as to how best to introduce the new product into the segmented target market. The plan describes three parts , The first part describes the market’s structure, size and behaviour, as well as the planned positioning of the product and the market share. The second part shapes the expected price, distribution approach and marketing financial plan. The last part of the marketing strategy outlines the sales and profit targets as well as the marketing-mix strategy. 5. Business analysis This is an important step in new product development. The firm must analyse different aspects of the new product. It should find out whether the product is profitable or not and what the cost of the new product will be. Under this stage, the demand for the new product should be established and whether the demand is seasonal or regular while also gathering information re any competitors of this new product. Estimations of sales and expenses such as; advertising and sales promotion should be made to provide calculations for the approximate profit which the  new product should render. Hence, the new product is studied from a business aspect. If the new product should earn a profit, it will be accepted, otherwise it will be rejected. 6. Product development In this product development stage, the company takes the necessary steps to produce and distribute this product since the company would have already decided to introduce this new product in the market. The production development department will make strategies to produce one or more physical versions of the product concept, while the marketing department will make plans on how to distribute the product. The financial department will provide all the finances required to introduce the new product. Before the test marketing stage, plans for the advertisements for the new product will be made on a small scale. 7. Test marketing Test marketing is introducing this new product on a small scale and in a small market, in a more realistic setting. If this product is a success in the small market, then it is later introduced on a larger scale. However, if this new product fails in the small market, then the company will test for reasons for its failure. There are different types of test marketing which include the following; sales-wave research, simulated test marketing, controlled test marketing and test markets . In sales-wave research, the company gives customers the opportunity to use the product at no cost. At a later stage the company then reoffers the same product or a competitor’s product at a slightly cheaper price and notes the number of times (sales-waves) each customer selects each product. The simulated test market is a cheaper and faster method when compared to the other methods, but it is not considered as the most accurate due to the controlled setting. The company will make necessary amendments in the new product and will then introduce it again in the small market. If the new product fails for the second time, the firm will reject it. Test marketing is a safety device which reduces risk from large-scale marketing. Although this is a very time-consuming stage, it must be done especially for costly  products. 8. Commercialization If the test marketing performed on the new product is successful, then the company introduces their product on a larger scale, which is known as commercialization. The firm will make a large investment in the new product. It will plan when to launch the product in a larger market and where since the market-entry timing and location are very critical. First entry has its advantage of being on the market before its competitors but might backfire if it is rushed. When a firm coincides its product’s entry with its competitors, known as parallel entry, this will enhance the market’s attention on analysing and comparing products. Whilst a late entry launch will reduce costs while also gathering further knowledge on the size of the market. Companies usually wait for the ‘killer application’ to occur; this may depend on the season or for the older product to be drawn down and to be replaced. The company will produce and distribute the new product on a larger scale where it will advertise the new product on mass media such as; Radio, TV, Magazine and Newspapers. The Consumer Adoption Process – This is the process by which potential customers learn about the new product, tests it out and adopts or rejects it. This process begins from when the consumer first hears about the new innovation up until final adoption of the product. Adoption is a decision made by an individual to become a regular user of a product. There are five stages which adopters of new products have been observed to pass through ; 1.Awareness – consumer becomes aware of the new innovation 2.Interest – the consumer seeks more information about the new innovation 3.Evaluation – the consumer considers whether or not to try the product 4.Trial – the consumer actually tries the product so as to enhance his/her evaluation of it. 5.Adoption – the consumer becomes a customer and decides to make regular use of the product. It is the task of the new-product marketer to make this process as easy and swift as possible so as to capture the consumer’s interest and turn it into th e action of actually adopting the product. Conclusion – In conclusion, companies must realise the importance that the product has in the marketing mix. Improved and replaced products will expand and maintain sales and profits for the company. However, when coming to develop a new product, companies must realise the importance and relevance of the steps involved in creating and introducing new products into the market. The key is to develop a product which is innovative, up to standard, meets the customer’s present needs and which ultimately has the ability to penetrate the market and claim a place in the customer’s minds. Thus by following the New Product Development process, as we have discussed in this assignment, companies will be able develop a product which has a high probability of being successful in the market and which will be demanded by its customers.

Computer Hackers Essay

The sub culture group of hackers has been around since the 1960s. The underground sub culture of hacking has evolved into a mainstream open community. Some famous hackers like Eric Corlery, Gordon Lyon, Gary McKinnon, and Kevin Mitnick have done their fair share of infiltrating network bases all over the United States. These people have a unique mindset that allows them to crack these codes set up by government officials. Eric Raymond tries to classify this group of people as crackers because they crack codes of computers but the community wanted to keep the name hackers. Regardless of the name the community of people is smart and can break down your computer at anytime. A hacker is a person who finds a weakness in a system and exploits it. Some motivation for hackers can be money, challenge, or pure adrenaline rush. There is a difference between a cracker and a hacker. Crackers are normally considered when people are involved with computers. There are several types of hackers all over the world. White hat hackers breach security for no reason at all. The term white hat means ethical hacker. A black hat hacker breaks into secure networks to destroy data or to make the networks not useable for those who are allowed to use it. Black hat hackers have a process called pre hacking to help them determine which network to hack. The hacker first looks for an open port to gain access to. After that is done the hacker will find ways to get vital information about the network to get into the system. Hackers will even go above and beyond to engage activities like dumpster diving. Dumpster diving is when people actually dive into a dumpster to get information like documents that can help them breakdown the network. A grey hat hacker is a combination of white hat hacker and black hat hacker. A grey hat hacker will surf the internet just to crack the network and charge the administrator to set up a firewall. Basically the hacker sets up the administrator without letting them know that they broke into their system. A social status among hackers is the elite hacker. These hackers are the most skilled in their field. Script kiddie hacker is the hacker that attempts to hack with pre packaged software. A neophyte is a non experienced hacker who really does not know what they are doing. They are new to the whole sub culture of hacking. A blue hat hacker is one who is outside of the security consulting firm who looks for places that have been exploited to patch up the weakness. Some attacks a hacker use are network enumeration, vulnerability analysis, and exploitation. There are techniques like vulnerability scanners, password cracking, and packet sniffer, spoofing attack, and rooting attack. A vulnerability scanner is a tool used to quickly check computers on a network for known weaknesses. Hackers also commonly use port scanners. These check to see which ports on a specified computer are open or available to access the computer, and sometimes will detect what program or service is listening on that port, and its version number. Password cracking is in essence guessing what the password could be to the administrator server. A packet sniffer uses data packets to catch the store data in the computer. Also hackers used techniques like intimidation, helpfulness, and name dropping to get people within a company to give out information regarding the servers so they may be able to attain the network information. At times these hackers come out successful. With so many worms and viruses like the Trojan horse a hacker can infiltrate your server and get all your information. There have been programs like Norton and MacAfee to help cut down on hacking. This sub culture like the thrill of breaking down walls and seeing what they are not suppose to see. Between people not being smart about certain things they do online and the hacker for setting them up, this issue of hacking can be a big problem. Not everything that is hacked is bad because government plans have risen to show what bad things they have created to ruin America. At the end of the day make sure you log out your account and get antivirus software to keep your account, your  account.

African creation myths Essay Example for Free

African creation myths Essay ? 1. Perhaps the answer that would best suit the question why life is so hard and then you die is how death is portrayed in these stories. There is suffering and hardship in one’s life because of disobedience of the hardships and commands of his gods. Death ultimately becomes the only â€Å"salvation† after so much hardship.   Had the living things and man obeyed the orders of their god, death would not have overcome these lives. In the story of the Plant of Life, the second wife, in her jealousy of not being considered by her husband despite the death of the first wife decided that in order to end her suffering must kill the plant that has taken the time and affection that would have been hers. Hence, ultimately, it is no wonder that in the end, the wife bears the consequent death of all living things. 2.  Ã‚   Basically these African myths hold women in the same way that women are being viewed today. Women are seen as being responsible for the ills that happened to society and life in general.   For example, in the story of the Plant of Life, the second wife was blamed for being the source of death when â€Å"she saw the plant and was jealous and cut it down with a hoe.† (Plant of Life). Such story shows how of little value women are because if the god did not play favourites among his wives, the story would not have ended that way. As a whole, women are viewed as being the cause of tragedies. 3. This myth basically starts out as a story of creation of the world and its five elements.   However, as the story intertwined itself it became a story not of creation but of destruction as each element became defeated by the other until at last Doondari, the god who created these things came down to earth and became the eternal one.   A very good point of interest here is how the story incorporated the attributes of men like sleep, blindness, worry and death and how these attributes became defeated when all of them became proud. It would seem that the writer wanted to emphasize that pride became the reason for the fall of its attributes and in the end, it was the god who has to put everything in its place. 4. One interesting thing about this myth is how Shida Matunda got afraid when the jealous wife killed the plant which what became of his favorite wife when she died. He is a god and yet he had no hold over life when in fact, he created the world and its living things. It would seem that as a god, he too depended on â€Å"higher beings† than himself and that he attributes life on these beings such as the plant which became the plant of life. 5. Between the myth of the Disobedience of Man and the story of creation in Genesis, one common factor emerges as to why one man disobeyed his Creator.   In this African myth, the root of the disobedience is the woman who failed to follow the orders of her god not to till the soil for food while in Genesis, Eve did not take heed in God’s warning not to eat the Forbidden fruit lest they will be punished. Hence, when they disobeyed the order of their gods, they were punished: the first beings in this African myth were sent with Death while Adam and Eve were banished out of the paradise that God created for them. 6. Indeed there is a great similarity between the myth Revolt Against God and the great Flood in Genesis although the manner of wiping out the face of the earth vastly differs with the version in Genesis.   In the myth of the Revolt against God, the gods wiped out the earth through fire whereas in the version of Genesis, the world was wiped out by the Great Flood.   Perhaps the reason why there is a similarity between the two stories is because we all came from the same roots.   Just like in the religions of   Christianity and Islam that traces its roots to Abraham, these stories of cleansing the earth may have also come from one original source and just branched out after generations of passing it. 7.   Ã‚  The gods in these African myths are not at all like gods but rather seemed like counterparts of men.   Although they have created the world, the living things and men, they never ceased to be like human beings who still feel the emotions of human beings or maybe they are simply reflections of the image and likeness of the beings they have created.   However, these African gods tend to be fickle-minded sometimes and would do whatever they feel like doing at the heat of the moment and that analyzing these myths, one can surmise that they are just exercising their power over their creations. African creation myths. (2017, Feb 28).

Becoming A Culturally Competent Counselor Essay Example | Topics and Well Written Essays - 500 words

Becoming A Culturally Competent Counselor - Essay Example I would describe my cultural identity development at the current time using the racial/cultural identity development. The first stage of my cultural identity development started with conformity. I accepted the dominant beliefs and customs being practiced by most people, and admittedly, I have discarded some of my own less popular and less dominant beliefs and practices. As a result, there was a certain dissonance because of the conflicting messages and observations inconsistent with my views of my culture and the dominant culture (Sanchez, n.d). I questioned the dominant beliefs that I conformed with previously. I saw how these dominant practices are unfairly damaging to my culture. After the stage of dissonance, I learned to completely embrace my cultural values and to reject the dominant beliefs. I also felt shame for abandoning my beliefs just because they were not popular. In the process, I regained pride in my culture and my beliefs. However, following the acceptance of my minor ity beliefs, I went through the stage of introspection where I learned to assess both minority and dominant beliefs and to integrate them into my life. After going through such process, I now developed an inner sense of security in my beliefs; I learned to accept people’s peculiarities and culture even if they were so different from the rest of the world (Sanchez, n.d). I learned that it is possible for the dominant and the minority beliefs to coexist, to take the strengths of each aspect and apply them in one’s life. Considering the nature of my cultural experience, five strengths I will bring to multicultural counseling will be my openness, my honesty, my sense of respect for other cultures, my perceptiveness, and my creativeness. I am open to people’s peculiarities and preferences; their having another culture or belief different from mine would not interfere in

Business Law - Assignment Example USA), the Supreme Court actually decided against the Pasquantinos, arguing that they have been guilty in violating Federal Wire Fraud laws. In this case, I don’t think that the Pasquantinos and the Hilts would not be able to succeed in their legal argument, given that the nature of the law was against smuggling, the very crime that the Pasquantinos and the Hilts committed. Meanwhile, with regards to the third case (USA v. Dotterweich); I think that he must still be held criminally responsible for violating the Food, Drugs and Cosmetics Act. Although it may be argued that he may have not participated directly in shipping misbranded drugs, this fact does not remove his responsibility to ensure that his business is actually complying with all standards and regulations that are being enforced by the state. In this case, given that it is still his company, such failure to comply with regulations is fully within his

Economic Benefits of the Law - Essay Example Sound science has not yet provided solid evidence to the claims that global warming is a critical threat (Potthast, & Meisch, 2012). Other scientists have even claimed that global warming has much attention than it deserves (Potthast, & Meisch, 2012). Global warming is likely to take place after hundreds of years and it is not yet a ticking time bomb as many put it. Many new scientists are afraid to go contrary to the global warming alarm just to protect their jobs and the alarmists take advantage of the ‘threat’ to obtain government funding for more academic research. The government has also taken advantage of the global warming ‘threat’ as excuses to increase tax. Moreover, alarmists use the ‘threat’ to attract huge amounts of donations from charitable organizations by claiming that they aim at saving the world.Additional Policies to Curb Emission of Greenhouse GasesIt is necessary that the US government employ additional policies to curb emis sion of GHGs for they are threats to the environment and public health as well. These new polices should regulate the transport industry which is major contributor of carbon dioxide to the air. The government therefore ought to encourage people to use vehicles that emit less carbon dioxide; these vehicles include electric and hydrogen powered cars. The government can achieve this by offering grants to the purchase of such vehicles in addition to providing recharging systems for the innovated vehicles. This way, Americans will develop the motivation to buy these vehicles.

Disney Culture, Social Responsibility and Corporate Identity Research Paper

Disney Culture, Social Responsibility and Corporate Identity - Research Paper Example The Studio Entertainment unit is the foundation on which the Walt Disney Company would be built, and at its heart are world-renowned animated features and live-action motion pictures. (Kotler 24) The Disney Company had a well defined corporate identity and worked extremely hard to control their public image. This resulted to businessmen and organization interested in placing Mickey Mouse character, logos and images on the cover of their products. The Consumer Products extended the Disney brand to merchandise ranging from apparel, toys, and books to interactive games, foods and beverages, electronics and delicate art. The founder of Walt Disney Company, Walt Disney died on December 15, 1966, of lung cancer. His persona that is the Walt Disney the character, and the role of Roy Disney and the creative input of nine old men, should never be underestimated while considering the history of the company (Michaels 45). Roy Disney took over as chairman, CEO, and president of the company after the death of his brother. One of his first acts was to rename Disney World as "Walt Disney World," in honor of his brother and his vision. Walt Disney had a vision of building Disneyland. These parks served as valuable role in shaping the Disney identity as well as for tourist attractions. Walt Disney could quote saying,† Disneyland began when my two daughters were extremely young. Saturday was always Daddy's Day, and I would take them to the merry-go-round and sit on the bench eating peanuts while they rode, sitting there, alone, I felt there should be something built of Family Park where parents and children could have fun together. (Williams 34) The death of Walt Disney snatched a brilliant innovator, who was constantly inventing and reinventing to keep his studio ahead of the game. Even after his death, the company, which bears his name, has continued with his philosophy. The new technique is the animated feature which is now more competitive than ever. The Walt Disney Co mpany Director, Emaritus Roy E. Disney, died on stomach cancer on December 16, 2009. During his time of death, he had owned roughly 1% of the Disney which could amount to 16 million shares. Roy Disney was the last member of Disney family to be actively involved in the operation of the Walt Disney Company and also working in the company altogether (Wasko 63). At the time of Roy Disney death, the Chief Executive Officer was Mike Eisner who took the reins in 1884. He could be credited for turning Walt Disney around through his policy of expansion into television, the internet, sports, publishing and music. Due to these range of media companies, problems continued to arise.

Obesity in Children Essay Example for Free

Obesity in Children Essay Conclusion Because the rate of childhood obesity is increasing at a disturbing rate, experts fear that this will cause a remarkable load of illness in the future of our children even now a growing number of diabetic young adults is becoming a norm. Preventing, identifying and treating of children and adolescents who are obese are becoming a core medical intervention priority for the government and all concerned institutions. Since there is not clear answer as to how and why children become obese and currently a variety of reasons blamed for this obesity including genetics, culture, habits, individual practice, parental practice, sedentary lifestyle, poor eating habits and such. Research at the molecular level has been progressing, but there is no actual understanding as to the whole image from a biological viewpoint. One might realize that there is no singular factor that can be blamed for a child becoming overweight or obese, it is a combination of factors that plays a role in promote obesity. The increasing obesity rates not only in adults but also in children these trends, in conjunction with obesity’s medical, psychological, and economic effects, emphasize the need for interventions and policy advice aimed at preventing obesity. Directives to remove soft drinks from public schools have started in some cities but despite the variety and number of researches done on the topic of obesity one may note that it remains to be a critical health problem. It seems that there are no enough intervention programs that have taken place in order to curve the problem. It is noted that not enough is being done in order to stop the rising trend of obese children but time has come that it must be addressed as a rising and critical problem that needs immediate attention if we are to cultivate healthy children. It will be noted that as children are obese and they are reaching their adolescence, the decrease in physical activity and the predilection to junk foods, fast foods and such also decreases the mental capacity of the child in a sense that they are more apt to laziness because of decreased energy rather go to school and participate in class, most of them are sleepy and usually uncomfortable in their own skins. It is of note that this problems if persistent will make for a bleak future for our children, since the society is cultivating lazy, fat children who will turn out to be lazy fat adults. One can imagine how it would be like in the future. Promotion of a healthy lifestyle not only for our children but for ourselves as well should be a major thrust of the government if curving the current situation is to be achieved. The thought at a young age children will be subjected to diseases and concern that is normally associated with the elderly and geriatric patients should be carefully considered and rejected. In developing an afterschool wellness program the author notes that it is not as simple as devising exercise plans for the children. It is a holistic approach that requires a multifaceted planning that includes education, healthy diet plans and the actual activity period. And it is also noted by the writer that in order to curve obesity in children, drastic measures must be employed not only by the obese children themselves but the whole family and the whole community. Developing healthy eating habits and leisure activity changes require changes that involve the family in order for the child not feel left out or forlorn. It is also of note that simple family physical activities will help curve obesity. One may realize that everything starts out at home and spilled over to the school then to the community. If we wish to curve obesity in children and protect our children’s health it is imperative that the community in particular and the nation in general work hand in hand so that attention maybe given and directives to promote healthy eating in schools and within the community be fostered and community get togethers that involves physical activities, community dances in the park, weekend exercise program for the community can be facilitated by the general community so that everyone may take part in keeping the family and our children healthier and live fuller lives.

Effects of the Geometrical Conditions on Side Channel Pump

Effects of the Geometrical Conditions on Side Channel Pump Effects of the Geometrical Conditions on the Performance of a Side Channel Pump: A review Appiah Desmond, Zhang Fan, Yuan Shouqi and Osman Majeed Koranteng National Research Center of Pumps, Jiangsu University, Zhenjiang 212013, China Abstract The side channel pump is a type of regenerative pump which plays a role in between the centrifugal pump and the positive displacement pump. This kind of pump delivers a high head at relatively small flows compared with other axial and centrifugal pumps even though it requires a low specific speed. This paper firstly focuses on the physical principle behind the flow characteristics illustrating the complex flow inside the side channel pump. Further discussions disclosed that, the hydraulic performance of the pump greatly depends on the variations of the geometrical parameters. This review draws conclusion that, enhancement of the computational modeling techniques will improve the efficiency of this pump thereby broadening its applications. Keywords: Side Channel Pump, Hydraulic Performance, head, geometrical parameters, computational modeling 1.0 Introduction The side channel pump since its inception in 1920 by Siemen and Hinsch [1] has had great influence in the world of engineering. This pump plays a role in between the centrifugal pump and the positive displacement pump. The side channel pump is a kind of regenerative pump which has a low specific speed and requires minimal Net Suction Pump Head (NSPH). Due to its unique properties to self-prime and transports both liquids and gas, it has been used mainly in the fields of oil and gas industry, mining and other applicable fields. Most of these pumps have the ability to handle liquid with gas or vapor inclusions up to about 50% and also other media close to their boiling point [2]. The side channel pumps base its operation on the momentum transfer principle moving from the impeller blade to the fluid in the side channel of the pump [3, 4]. The side channel pump delivers a large head performance at relatively small flows [5]. The fluid gets into the pump and leaves after numerous impeller movements. The fluid velocity and its head increase causing it to have the capability to produce a head (pressure) compared to the axial and centrifugal pumps. Due to the smaller pressure difference, a fluid entering this type of pump closer to its vapor pressure is less susceptible to the pressure change that can bring about cavitation[4]. Over the years, the enhancement of the total efficiency of this pump still remains a challenge to engineers and scientist. The flow rate of fluid in the side channel pump is significantly influenced by the impeller designs on this basis urgent attention needs to be given to the design and optimization of the impeller and side channel [5, 6]. 2.0 Flow Mechanism The side channel pump mainly features a side channel in figure 1a. and an impeller usually with 18 to 26 blades figure 1b, which delivers the fluid circumferentially. The assembly of the side channel and the impeller is shown in figure 1c. The fluid flows in a straight line from the inlet of the pump and leaves through the outlet in a helical form after numerous re-entries into the rotating impeller. This effect causes an upturn in the pump head (pressure) from about 5~10 times better than the impeller of a common pump rotating at the same speed [5, 6]. side channel (b) radial impeller The assembly of side channel and impeller Figure 1: Typical side channel with radial impeller This makes the flow of fluids in this kind of pump very complex as depicted in figure 2. The pump does not transport the same volume of fluid that enters out meanwhile some portion of the fluid moves back into interrupter gap and is conveyed by the pressure side of the blade to the suction side [6]. Shirinov and Oberbeck [3] explained the movement of gas in the side channel pump. They pointed out that the momentum acquired by the blades of the impeller is transferred to the gas. The velocity of the gas is then increased both in the axial and radial direction by the impeller blades in the side channel. Figure 2. Flow pattern of liquids in the Side Channel Pump [5] The turbulence and the circulation models are largely used to describe the performance of the pump and also the characteristic curve computation. The side channel pump efficiency is usually below 40% because it is a type of a regenerative pump [5, 6]. Basically, the flow is very dependent on the orientation of the impeller, impeller blade and the side channel. There are many configurations of the impeller blade and shapes of the channel as depicted in figure 3 by Song et al. [7]. Figure 3: Different kinds of blade and channel shapes [7] A study by Senoo [8] on the influence of the developing area for different geometries of the inlet region of the regenerative pump observed the large channel region at the inlet port as capable of developing high pressure head leading to a better cavitation performance of the pump. Song et al. [7] developed a model for the flow theory in the regenerative pump to help address the lapses in the works of Senoo[8] and Wilson et al. [9] which mainly concentrated on the exchange of momentum of the flow. There were inaccuracies of some of the models suggested by [8, 9] to reduce the losses and slip factor links. This made the accurate prediction of the off-design flow conditions very incapable. Song and his colleagues [7] concentrated on introducing vibrant mathematical algorithms demonstrating the true behavior of the flow in the developing area of the inlet region. They based their research on assumptions which guided them in arriving at some meaningful conclusions. The velocity triangle relation between absolute velocity, V relative velocity, W and the impeller velocity, U was defined based on the velocity triangle in figure 4 at blade inlet, R1 and blade outlet, R2. Figure 4: Velocity triangle at locations R1 and R2 [7] From figure 5, there is no tangential velocity in the front and rear faces of the blade region. Thereby, the continuity was defined in equation 1 based on their first assumption that the flow should be steady and incompressible. (1) Figure 5: Elements of one side channel and blade [7] They developed the first-order nonlinear Ordinary Differential Equation (ODE) for predicting the circulatory velocity which showed a good agreement when its results were compared with that of experimental results. A new branch of fluid mechanics developed in the last decades called Computational Fluid Dynamics (CFD) has been employed lately in the modern engineering science to analyze the flow of fluids in turbo machines. The study of the fluid flow in the side channel pump using the CFD tool and an analytical method was the centered of BÓ §hle and Mullers [10] research. They developed an analytical model for the flow taking into consideration some assumptions. A momentum balance was expressed for the control volume of the flow in a circumferential course. (2) Where Cin = uniform velocity in circumferential course Csc = uniform velocity in the side channel à ¡Ã‚ ¹Ã‚ exch = mass exchange flow p = static pressure A =Side channel cross-section area A1 = surface control volume à Ã¢â‚¬Å¾ = mean shear stress Figure 6: momentum balance [7] The efficiency of the impeller and side channel was defined as (3) Where ÃŽÂ ·imp = impeller efficiency Pexch = Exchange work Power Pshaft = Power of shaft Phydr = Hydraulic power losses (4) Where ÃŽÂ ·sc= side channel efficiency Peff = effective power à ¡Ã‚ ¹Ã‚  = side channel pump mass flow g = acceleration due to gravity H = head of side channel pump Cin = uniform velocity in circumferential course = flow rate volume A =Side channel cross-section area Based on the efficiencies of the impeller and the side channel, the efficiency of the side channel pump, ÃŽÂ · was computed to be (5) Later, Kristof and his colleagues [11] also applied the CFD to model the flow course in the side channel pump as displayed in figure 6. A technique was modeled to optimize the orientation of the blade and the shape of the side channel to control the flow losses. They carried out simulations with the k-à Ã¢â‚¬ ° turbulent conditions based on a 40100 cell tetrahedral mesh. Figure 6(a) and (b): Typical flow course with the side channel pump [11] In 2005, Engeda and Raheel [12] presented mathematical tools capable of examining the complex flow inside the regenerative pumps. These mathematical tools were used also used to develop the prediction performance code for regenerative pumps 3.0 Effects of the Geometrical design of the parameters of the Side Channel Pump The performance of the regenerative pump was examined by Iverson [13] with his focus on the shear stress generated by the impeller on the fluids. He then confirmed on his resulting expressions (two shear coefficients and an average impeller velocity) through experimentations. A mathematical tool was proposed by Wilson et al. [9] to investigate the performance of regenerative pumps which used radial blades. Equal pressure head rise and circulatory velocity through the channel region was anticipated by Wilson and his team. Much attention was given to the spiral flow to achieve many ways of curtailing the losses. Their results provided experimental verification after comparing the numerical and experimental performance curves. Yoo et al. [14] also tried to develop advanced mathematical equations to calculate the geometry of the rotating flows. They offered enhanced models to examine the flow rate, the average radii of the inlet and outlet impeller and the slip factor based on the exchan ge of momentum proposal by Wilson et al [9]. The models required an experimental boost to evaluate an empirical number in the proposed experimental model. The effect of the blade angle was not considered thus limiting the applicability as a design tool. The variation of the radial blade numbers, the clearance and the channel region of regenerative pumps were conducted by Shimosaka and Yamazaki [15]. Investigations conducted by varying the dimension of flow channels, impellers and clearances on a regenerative pump concluded that, the characteristic dimension of the flow channel is related to the clearances effects, which in turn influences the pump efficiency. The characteristic dimension of the flow channel was introduced as a special dimension which was given as: (6) Where Rmis the characteristic dimension of flow A is the cross-sectional area of the flow channel is the circumferential length of the blade(vane) Figure 7: Flow channel and blade profile They reported that a suitable Rm would yield a high efficiency of the pump. Therefore, the value of the Rm determines the permissible clearance. The pump efficiency was also strongly influenced by the number of blades (vanes) which is dependent on the characteristic dimension of the flow channel, the thickness and length of the blade and the width ratio as shown in figure 7. It was established that the efficiency of the pump varies with different width ratios of the vane groove which aids in the determination of the blade number. Width ratio,(7) Defining Z = Number of blades D = Diameter of impeller t1 = Peripheral width of blade groove t2 = Peripheral length of blade groove Additionally, Yamazak et al. [16] also carried out works to investigate the efficiency of the regenerative pump. Unlike Shimosaka and Yamazaki [15], they used the non-radial blades and concluded that the blade angle and the cross-sectional area of the flow channel play a vital role in the determination of the head (pressure) loss in the flow channel. Άh = Hs Hmin(8) Where Άh = the magnitude of head loss Hs = the suction head Hmin = the minimum pressure head in flow It was noted that the magnitude of Άh reduces to almost half that of water with the same velocity in the event of high viscous liquid. Motivated especially by the observations made by [15, 16], Grabow [17] also took into consideration the effects of the impeller, the number of blades and the role of the radii and thickness of the blades during his research study. The blade angles were varied to define a very satisfactory exchange of energy and pressure head levels, which in effect helps to evaluate cavitation performance better. Bartolini and Romani [18] also affirm that, the flow rate of the regenerative pumps depends on the optimization of the impeller flow. A new theory was proposed by Badami [19] on the calculation of the circulation flow rate of the regenerative pumps. This model took into account the field of the centrifugal force in both the side channel and the blade orientation. Also, his work also considered the influences of the geometry of the blades (number and angles) and the area of the side channel. Earlier it had been discussed by Sachs and Shirinov [20] that the best number of blades depends directly on the diameter of the impeller and inversely proportional to the side channels size. After that work, Shirinov and Oberbeck[3] then focused their investigations on the transportation of gas in the side channel pump by using different blade profiles. They compared C, V, and Y blade profiles with the radial (T) blade profile as shown in figure 8. Figure 8: Impeller with different blade profiles After comprehensive comparisons, it was established that blade profile C gave an optimal performance at pressures exceeding 20kPa meanwhile at pressures from 100Pa to 20kPa, the impeller with blade profile V (Chevron) recorded an optimal performance because there was a high transfer of momentum from the impeller to the gas inside the side channel within such pressure range. An extensive experimental research was also conducted by Choi et al. [21].Their work was mainly focused on the limitations of [14, 15, 17]. They examined the effects of the geometry on the blade on the efficiency of regenerative pumps. Ten different configurations of blades which comprised straight inclined blades with angles of 0 °,  ±15 °,  ±30 ° and  ±45 ° and chevron impeller blade with chevron angles of 15 °, 30 °, and 45 ° were used in conducting the experiments. The measured performance of the pump were measured based on the dimensionless flow à Ã¢â‚¬ ¢, head coefficient, à Ã‹â€ , efficiency, ÃŽÂ · and power coefficient, à Ã¢â‚¬Å¾. (9) Where Q = volumetric flow rate Qs= rigid-body rotational volume displacement rate (10) H = head Ug = rigid body rotation velocity g = acceleration due to gravity (11) The experimental results showed that the pressure head and the pump efficiency is greatly related to the geometry (shape and angle) of the blade as revealed in figure 9(a) and 9(b). Figure 9(a). Pump curve characteristics for the different blade orientation [21] Figure 9(b). Efficiency curve characteristics for the blade orientations [21] The chevron blade(V-shaped) with chevron angle of 30 ° recorded the highest head performance with a better pump efficiency as revealed in figure 8(a) and 8(b) after a comparative test of all the ten blades showing that there was an optimum chevron angle of around 30 °. This report showed good agreement with the work of [3] because of the high energy transfer at high pressures. The variation of the Reynolds number plays an important role in the performance of the regenerative pump computationally and experimentally. It was established by Horiguchi et al. [22] that, as the Reynolds number declines the pressure head of the regenerative pump rises at low flow rate and reduces at high flow rate. This effect of the Reynolds number is greatly affected by the degree of the shear force applied the impeller and the shear stress exerted by the fluid on the casing wall. Meakhail and Park [23] with the help of the CFD put forward an improved model to enhance the efficiency of the re generative pump. They based their arguments on the experimental works conducted by Meakhail et al. [24], Abdou et al. [25] and Abd El-Messih et al. [26] on the same kind of pump. They then confirmed their numerical model with the experimental results which were in good correlation. Figure 10a: Spiral flow course [23] Figure 10b: Impeller and Side channel dimensions [23] The improved model considered the tip (ÃŽÂ ²2), side (ÃŽÂ ²2s) and inlet (ÃŽÂ ²1) angles since a part of the fluid flowing leaves at the tip of the impeller and the other part of the fluid leaves at the side as indicated in figure 10. The CFX software was used to compare the efficiency of the pump with radial blades of different ÃŽÂ ²2s at the tip of the blade and ÃŽÂ ²1 for the same ÃŽÂ ²2. They confirmed that the side-blade angle has a significant effect on the performance of the side channel pump. The FLUENT software was applied in the examination of the flow of the fluid in this kind of pump by [27, 28]. The experimental results corroborated the CFD analysis. They also used a one-dimensional method to describe the energy transfer inside the regenerative pump and estimate the influence of the geometry of the blade on the efficiency of the pump. The performance of the regenerative pump was examined by Karanth et al. [29] numerically with the help of CFD. They studied the complex nature of the flow of fluid inside the regenerative pump. It was discussed that the number of impeller blades had a great significant on the performance of the pump. The head performance of the pump appreciates with the increase in the number of blades. Following the works of [29] the CFD was also applied by Maity et al. [30] to simulate the flow of fluids in regenerative pumps. It was established from their work that the pressure head loss can be minimized by curving the outlet flow domain as indicated in figure 11. Figure 11: Regenerative Pump model displaying the curvature in the outlet domain [30] It was indicated that there is a high rotating stalling flow at the outlet of the pump because of the reduction of the area. This effect enhances the static and total pressure across the pump. Hence, the curvature in turn increases the net pressure head by reducing the vortex flow as in shown in figure 12. Figure 12: Bar diagram showing the total pressure for the Pump model with outlet domain curvature [30] They also ended that, the net pressure is significantly enhanced by locating the blades on either side of the impeller by offsetting. Moreover, the net pressure is also affected by varying the number of blades on either side of the impeller. Fleder [31] numerically and experimentally examined the effects of the geometry of the blade on industrial side channel pumps in 2012. Two different impeller blade profiles were developed using ANSYS CFX 13.0 and subjected to investigations as shown in figures 13 and 14. Figure 13: Design of the Side Channel Pump [31]Figure 14: Impeller Blade Profiles [31] He concluded his work after comparison of the computational and experimental results. The experimental validation was done with a rotational speed of 750 rpm. The Imp 1 depicted good accordance both numerically and experimentally. Meanwhile, Imp 2 recorded a faster head rise because of the higher circulation frequency. This, in turn produces a greater multi-stage influence as depicted in figure 15. Figure 15: Assessment of the pressure head performance of the simulated and experimental results for Imp 1 and Imp 2[31] In addition, Fleder again with Bohle [32] carried out advanced studies to improve the performance of the side channel pump. In this paper, they extended their scope not only to cover the blade profile. The impeller diameter, the size of the gap, interrupter size, side channel height and the shape of the side channel were the main parameters considered. Variation of the height of the side channel, h, the width of the blade, w and the length of the blade, l, were applied to two different pump models in figure 15. Pump Model A Pump Model A Impeller Diameter = 150 mm Impeller Diameter = 160 mm Gap Size s, = 0.2 mmGap Size s, = 0.4 mm Interrupter size = 300Interrupter size = 460 Side Channel height, h = 35 mmSide Channel height, h = 40 mm Shape of Side Channel = semi-circleShape of Side Channel = Straight Figure 16: Variations in the pump models A and B [32] Figure 17: Parameters of the Side Channel Pump [32] The ICEM software was applied to develop the computational models which were meshed using the structured hexahedral multi-blocks grids. They chose k-w-SST profile to assess the flow fluctuations. It was gathered that the efficiency of the pump is dependent on the ratio of the side channel height, h to the blade length, l. Furthermore, sharper pressure head features and meaningfully greater efficiencies are achieved with a gap reduction of the pump. The work done by [21, 31, 32] on the influence of the blade angle motivated Nejadrajabali et al.[4] in 2016 also to analyze the pattern of the flow and the improvement of the efficiency of the pump by modifying the geometry of the blades. Their focus was on the effect of the variations of the angle of the blade, ÃŽÂ ² numerically on the efficiency of the regenerative pump such as the side channel pump. The investigations were carried out using two sets of impellers i.e. (the symmetric blade angles and asymmetric blades angles). The symmetric blade angles were designed with the same inlet and outlet angles of  ±10o,  ±30o and  ±50o whiles the asymmetric blade angles were also designed with the inlet set to 0o and different outlet angles ranging from  ±10o to  ±50o as illustrated in figure 18.

It was pointed out after the numerical simulations that, the forward symmetric blade angles compared with the other models recorded higher coefficients of heads and displayed a better performance. Recently, Zhang together with his colleagues [33] improved the head pressure performance of the side channel pump by varying the suction side blade angles from 00 to 300 as indicated in figures 19 and 20. Figure 19: Cross-sectional area of the blade [33] Figure 20: The impeller with various suction side blade profile angles indicating ÃŽÂ ¸ = 100, ÃŽÂ ¸ = 200 and ÃŽÂ ¸ = 300 [33] The CFX 14.5 commercial software was used to simulate the turbulence based on the k-w SST model. After experimentally comparing the results with the numerical simulations, it was recognized that the head performance appreciates with increasing suction side blade angles within a certain range. Even though the impeller blade profile with suction angle 300 recorded the optimal head performance, there was no significant advancement in the efficiency of the side channel pump. The regenerative pump (side channel pump) records efficiencies lesser than other types of pumps like the axial and centrifugal pumps. BÓ §hle et al. [34] lately attempted to improve the efficiency of the side channel pump by using the direct method in the context of the CFD simulations to calculate the massive losses which are associated with the various kinds of internal flow patterns of the fluid. The second law of thermodynamics was main physical principle applied in the estimation of the internal losses due to the flow patterns. According to Spurk and Aksels [35] proposal expressed in equation 10, the specific entropy s is a state variable agreeing with the second law of thermodynamics appreciates in all real and irreversible mechanical process in the case of turbomachinery.

Buick and Budweiser- Selling Success and Patriotism :: Media Advertising Essays

Buick and Budweiser- Selling Success and Patriotism Television commercials go beyond merely informing consumers about products or services: these advertisements sell their abstract ideas that tend to be valued in American society, such as success and patriotism. Two examples are outstanding commercials produced by the car manufacturer General Motors for their Buick cars, and the brewery Anheuser-Bush for their beer, Budweiser. While David Barry, in his essay, â€Å"Red, White, and Beer,† humorously describes the connection between commercials and values, Rita Dove and Marie Winn, in â€Å"Loose Ends† and â€Å"Television Addiction† respectively, are about an addiction to television and how television creates unbelievable ideal of a reality. Analyses of these two television advertisements, not only make a connection between their products or services and the abstract ideas of success and patriotism, but in the process, also sell the ideas as important American values in a powerful manner accomplished only b y television, because of people’s addiction to it. The General Motor’s car commercial features the professional golfer, Tiger Woods, on the golf course. He makes golf shots that seem impossible such as making a shot from a suspended bridge. Also, he is surrounded by famous people. While he is making these amazing golf shots, there is always a Buick vehicle at the background, and in some cases, Tiger Woods uses a Buick as a golf cart. The commercial has no plot, however, the visuals are stunning and the Buick is always prominently displayed in the picture. The fame of Tiger Woods is highlighted through the class of the car he drives as well as the seemingly impossible golf shots he makes with little effort. On the other hand, the Budweiser commercial features a donkey that is disheartened as he can not be a part of the elegant, beautiful Clydesdale horses which are the mascots for Budweiser. Determined, the donkey practices by pulling a cart with beer, prancing about, and changing his appearance. Finally, he comes before a group of Clydesdale horses to be interviewed; however, he â€Å"he-haws† like a donkey and thus thinks that he will be rejected. Despite his fears, he is accepted as a Clydesdale. These two humorous and classy commercials are aimed at selling cars and beer, in an unrealistic manner; however, they go beyond product marketing to selling the values of success and patriotism in an unrealistic manner too.

Government, Media, Censorship and Terrorism †Perhaps We Can’t Handle t

Government, Media, Censorship and Terrorism – Perhaps We Can’t Handle the Truth Government and media influencing each other is a tender ethical situation. Initially, it seems simply appalling that any government would either censor or use its media as a tool, but considering the possible benefits of such acts makes the issue more complex. What if censorship saves lives? What if manipulating the media brings a resolution to a conflict? Wartime especially brings these questions to the forefront. When peoples lives are at stake, often standard rules of morality must either be reconsidered or suspended. Wartime is also the only situation in which the government could get the support of such practices from a constituency with a free press. Practiced responsibly, censorship and manipulation can be quite effective. Although, there is always the legitimate fear of the slippery slope. First, I would like to examine media manipulation. In the United States, in accordance to our press tradition, this is seen as an absolute travesty. No self-respecting journalist w...

The St. Catharines Standard :: essays research papers

The St. Catharines Standard   Ã‚  Ã‚  Ã‚  Ã‚  I choose to do my essay on the St. Catharines Standard. The Standard is the St.Catharines and Thorold area newspaper. It provides us with the local news, advertising and it keeps us in touch with what is happening all over the world. It was first owned and runned by the Burgoyne family and was printed in St. Catharines but, was sold last year to Southam Inc. and has started to be printed in Hamilton. Southam Inc. also owns other papers such as The Hamilton Spectator,The Ottawa Citizen and The Kingston Wig. Here are some questions that I have made up about The Standard and I have found the answers for them. 1. How important is The Standard to our economy?   Ã‚  Ã‚  Ã‚  Ã‚  The Standard is pretty important to our economy. It provides the peoples of St.Catharines and Hamillton with jobs. It also let's the local businesses advertise their business to the people and attracts businesses to St. Catharines. Which brings money to the city. And finally, I provides St. Catharines with the daily news about the city and all over the world. 2. What is the source and type of the paper and why is it used?   Ã‚  Ã‚  Ã‚  Ã‚  The Standard gets their paper from wherever they can get it the cheapest. It is Recycled Newsprint. Recycled newsprint is paper that has been previously used paper that has been shredded, de-inked and then turned into pulp so it can make paper again. This type of paper is used because its economical, lightweight, recyclable and is available world wide. 3. What is the process of making the St. Catharines Standard?   Ã‚  Ã‚  Ã‚  Ã‚  The First step in making the newspaper is in the advertising department. The workers in the advertising dept. sell space in the paper to local businesses for ads. This pays for the paper to be made. Then the ads are produced and are redied for the paper a day before it has to be made. After the ad space is sold the paper is sent up to the editorial room so they can look at the space not occupied by ads and decide what stories the need to fill up the paper. Now to make the paper! The pages are assembled and the ads and stories are cut and pasted on to boards. After that a negative is shot of the board.

Why did Stalin emerge as the leader of the USSR in 1929? Essay

There are many reasons why Stalin emerged as the leader of Russia, some of these are due to his intelligent mind and determination for power, others because of his criminal mind-set and willingness to overcome his rivals. The most important reason why Stalin emerged as leader of the USSR is because he manipulated his party members and his own place within the party, he did this by recruiting his friends and supporters into the party after the Lenin Enrolment, as well as this Stalin removes any competition within the party that may contribute to a threat, this shows how Stalin abuses his own position in the party to manipulate everyone into getting what he wants. Having his supporters within the party, Stalin could not be voted out or overpowered within the party. One of the important reasons why Stalin emerged as leader of the USSR is because of his individual factors, because of Stalin’s previous convictions of bank robbery and treachery he was not trusted straight away, but because he is devious and knowledgeable person he stayed back in the party until the right moment struck, when Lenin had the stroke, Stalin saw his opportunity to get into the hierarchy of the party, this shows that Stalin’s devious mind played a large part of why Stalin emerged as the leader. Stalin’s personality served him well to becoming the leader of the USSR, this is shown when he sent a telegraph to Trotsky explaining when the funeral of Lenin was, unknown to Trotsky, Stalin had actually gave him the wrong date and made a big funeral, this was seen as Trotsky being dishonourable, making him less likely to succeed Lenin, this improved Stalin’s chances of succeeding as Trotsky was him main competition. The true nature of Stalin’s p ersonal traits is shown when he keeps Lenin’s testament secret, knowing what Lenin thinks of him Stalin seems motivated to win leadership, by being devious Stalin stopped the corruption of Lenin’s testament getting publicised therefore making him in line for leadership.

The Military in Art

The word propaganda has come to have sinister overtones though this was not always the case. Propaganda today evokes images of sinister lies and obfuscations told by enemies of the state to sway the minds of the citizens. Yet in a larger sense all art is propaganda to some degree and military art is propaganda on a grand scale. Art is designed to cause an emotional response in the viewer. Throughout history artists have served the state, willingly or not so willingly, in an effort to further the aims of the government, be it republic or clan of elders.   Those works of art that are most effective are those that hit the viewer viscerally and cause a response that is near equal to the actual event being depicted in the art work. The works mentioned here are like that. I served in the United States Air Force for six years as a military policeman. I have traveled to Saudi Arabia, Kuwait and Korea. I have seen artwork that has evoked emotion in me and I have seen art that was truly representational of the events I have seen. James Dietz’ work, I Shall Defeat Them on the Battlefield, can be found as a limited edition print from the online gallery of the artist. The image size is 36† x 21.5 â€Å". It depicts the United States Army 75th Ranger Unit on the ground. This unit remains the Army’s premier special operations force capable of conducting a full spectrum of operations to include direct action raids and forced entry operations (JamesDietz.com). Dietz depicts an action scene in a dim setting. In the background is the skyline of a city that was ancient in the days when Christ walked the lands of the Middle East. The modern warriors, carrying firearms and dressed in body armor seem incongruent beneath the palms and the domed edifices creating the negative space in the lower portion of the sky. An automobile is in the streets where camels would seem more at home, juxtaposed in contrast to the ancient city and the modern warriors, signifying a delivery system of enemy fire. First Boots on the Ground, by William Phillips, is now available as a limited edition print, measuring 31† x 19 â€Å". It is a classic scene from the Viet Nam era, featuring a sky filled with helicopters and reminiscent of Apocalypse Now. The work depicts the 1965 battle of La Drang Valley, famous for its intensity.   â€Å"At 10:48 the helicopter touches down, and Lt. Col. Moore, Sgt. Major Plumley, Capt. Metsker, Bob Ovellette, Al Bosse and Vietnamese translator Mr. Nik become the first boots on the ground at La Drang† (OzarkAirFieldsArtworks 2005). This art is compelling and personal to me for it depicts the ultimate in warfare, that time when the soldier commits and becomes a weapon aimed at the heart of the enemy. He has left the relative safety of the helicopter. He no longer is behind the line depending on artillery or mortar fire, but rather advances, putting his life on the line as he moves inexorably toward the opposing warrior. Charlene Cooper’s moving artwork, titled with the acronym B.O.M.B., signifying Blood of My Brothers, is a drawing in graphite and colored pencil. The intense blue of the flag is complimented by the red of the tear streaming down the face of the warrior. It appeals to me for reasons that would be clear to most combat veterans, as it shows the side of a soldier seldom seen or discussed openly. The man holds a folded American Flag as that single tear, executed in the red of blood, is seen to escape his eye. He shows the pent up emotion which soldiers rarely display and gives the viewer the understanding that he is a flesh and blood creature, endowed with all the sentiment and feeling of any other man. He is proud of the job he has done, but keenly aware of the price that was ultimately paid by so many of his friends and compatriots. I find Cooper’s work the most compelling of these three, for it appeals to a side of me that is most often hidden from the view of others. It touches me in a place where I am alone with my feelings and appeals to me on a spiritual level. Even her choice of title is compelling, bringing to the piece a thought-provoking message that transcends the art and gives the viewer ideas that there is more to the piece than what appears on the surface, making it multi-leveled and multi-dimensional.

Discuss with reference to two other poems Essay

Crossing the Bar’ contains the most powerful presentation of death in the anthology. To what extent do you agree? Discuss with reference to two other poems in the collection – Tennyson question Tennyson presents death in different ways in ‘Crossing the Bar’, ‘Break break break’ and ‘Morte D’Arthur’. Each presentation is powerful however; it is difficult to decide whether ‘Crossing the Bar’ contains the most powerful presentation because it depends on what type of death the reader finds the most significant. If it is the death of one’s own life, then ‘Crossing the Bar’ might seem more powerful because it is a representation of Tennyson’s complacency with his own death. But, if the death of a friend relates more to the reader’s personal experience, death in ‘Morte D’Arthur’ could be more meaningful and powerful. To some extent I do not agree that ‘Crossing the Bar’ contains the most powerful presentation of death in the anthology. Both ‘Crossing the Bar’ and ‘Break break break’ use imagery of the sea to convey different meanings. In ‘Crossing the Bar’, the sea represents the world the speaker will transgress into after death. ‘And may there be no moaning of the bar, when I put out to sea’. Tennyson uses the metaphor of the sandbar to describe the barrier between life and death. One side of the sandbar is life and the sea on the other side is death. This is a powerful representation because Tennyson sets out a distinction between the two worlds clearly, suggesting that death should be embraced because it’s now peaceful and natural. ‘And may there be no sadness of farewell, when I embark’. This is in contrast to the normal response of death, which is indicated in ‘Break break break’. In ‘Break break break’ the speaker displays feelings of anguish and pain, this is shown in the title. The repetition of the word ‘break’ emphasises the onomatopoeic sound of a heart breaking. It could also be interpreted as waves breaking on the rocks. ‘Break break break at the foot of thy crags, O sea! ’ This quote describes how life progresses in an endless cycle even in the event of the death. The effect of the ‘O’ and exclamation mark at the end punctuates the speaker’s frustration that life still continues to go on. The speaker takes on a tone of bitterness that the world is not morning with him. ‘O, well for the sailor lad, that he sings in his boat on the bay! ’ In contrast, the use of an exclamation mark in ‘Crossing the bar’ demonstrates the speaker’s excitement of death instead of feelings of enragement. ‘Sunset and evening star, And one clear call for me! ’ This shows how the speaker is compliant of death because it is their own life and they are ready, however in ‘Break break break’ the speaker is demoralised because death has taken their friend without warning. ‘Crossing the Bar’ and ‘Break break break’ both present death powerfully, however ‘Break break break’ may appear more powerful because it uses an expression of grief caused by loss and uses intense emotions, like anguish. Then again, to some extent I do agree that ‘Crossing the Bar’ contains the most powerful presentation of death in the anthology, especially in comparison with ‘Morte D’Arthur’. A similarity between ‘Crossing the Bar’ and ‘Morte D’Arthur’ is that they both discuss religion and relate them to death. King Arthur’s death in ‘Morte D’Arthur’ can be seen as an allegory for the loss of honour and chivalry in an increasingly materialistic age. ‘And the days darken around me, and the years, among new men, strange faces, other minds’. Arthur and his knights at the round table can be interpreted as Jesus and his disciples. ‘But now the whole round table has dissolved, which was an image of a mighty world. ’ The presentation of death here appears powerful because it is the removal of a higher authority, which has followers and believers just like religion. If a God is removed, then the religion will fall apart because it no longer has a leader. This makes the death of Arthur seem even more significant because it represents the collapse of civilisation. ‘Ah! My Lord Arthur, whither shall I go? ’ However, ‘Crossing the Bar’ uses religious connotations such as ‘crossing’ to describe the speaker’s journey into the next world or crossing into faith and devotion. Tennyson complements this metaphorical link with a spiritual one as he hopes he will see his ‘Pilot face to face’. This can also be interpreted as Tennyson hopes to see Hallam in the Pilot, however it is more likely that Tennyson is discussing a Christian God. This is because seeing God face to face is a biblical theme and the transition from life to death in Christianity allows people to join God in heaven, which is beyond ‘Time and Place’. The presentation of death in ‘Crossing the Bar’ may appear the most powerful because unlike ‘Morte D’Arthur’, death becomes an end that is not confusing. In ‘Morte D’Arthur’ Arthur goes to Avilion, which could be a metaphor for heaven. However, he leaves behind a disorientated world with a lack of guidance. In comparison, the bar in ‘Crossing the Bar’ is also a metaphor for heaven, but the crossing is far more peaceful and conclusive. To conclude, I believe that ‘Crossing the Bar’ contains the most powerful presentation of death because in contrast to ‘Break break break’ Tennyson is conclusive – he is being valiant about his own deaf or has come to terms with the grief of his friend and is ready to be reunited with him. ‘And may there be no moaning of the bar’. Even the structure of the poem can represent the shortness of life. By having fewer words, they can hold more control and capture the attention of the reader. In contrast, ‘Morte D’Arthur’ is longer and this makes the presentation of death less powerful because the meaning may be lost as the poem is read.
