The Kennewick Man Controversy

The â€Å"Kennewick Man Controversy† has been an issue debated among scientists and the Umatilla tribe. The debates focused on the question of who should take ownership and immediate possession of a human skull found at the edge of the bank of the Columbia River. Archaeologists argued for a right to study the human skull, causing the legal battle to stretch for several years until scientists were allowed to study the â€Å"Kennewick Man†.The discovery of the skull paved the way for realizing the urgent need for archaeological analysis and gave rise to certain ethical contentions which drew the lines between scientific and cultural pursuits. In this paper, I argue that archaeological study is an immediate need that should overcome certain ethical and cultural considerations for a specific duration. There are scientific limitations and ethical issues raised by the debates over the Kennewick Man. Scientists arguing for the right to study the human skull are limited by an e xisting law of the United States: the Native American Graves and Repatriation Act.Also, once scientists are permitted to study the human skull, their study’s length will be limited not only by their scientific tools but also by the demands of the Umatilla tribe to take possession of the remains the soonest possible time. One of the results of the scientific study conducted reveals that the Kennewick Man did not fit any of the modern classifications of â€Å"race† and that more is yet to be known about the identity of the human skull (Fiedel, p. 86). As far as ethical issues are concerned, the controversy has stirred the delicate balance between the importance of scientific research and the respect for cultural beliefs.The major point raised by the archaeologists—that the human skull needed archaeological analysis in order to solve the â€Å"puzzle†Ã¢â‚¬â€came in conflict with the contention of the Umatilla tribe, which is that they have a claim to the bo nes and, therefore, it is only proper to repatriate the bones to them. On closer inspection, the granting of the permission of the archaeologists does not necessarily imply the higher significance of scientific analysis over the cultural rights of the Umatilla tribe in general.Permitting archaeologists to examine the remains only signify that there is an urgent need to study the skeletal material. The fact that the law forces the scientists to return the artifacts after examination signifies that, in the long run, the ethical considerations for the cultural rights of the Umatilla tribe still weighs more than scientific pursuits. Elizabeth Weiss argues that â€Å"the demand to bury aboriginal skeletons, not only in America but also around the world, poses a potentially serious impediment to scientific inquiry† (Weiss, p.13), to which I fully agree. While we should consider the cultural rights of native groups to their heritage and cultural property, the examination of archaeol ogical findings to expand the human understanding of human civilization’s evolution is likewise a significant thing to consider. Legal arrangements can be made in order to preserve the integrity of the skeletal material during archaeological analysis under a prescribed length of time and to guarantee the claimants of the skeletal remains that they will have possession of the object after the study.To this day, modern scientists are still seeking the humble beginnings of humanity through what is little that remains of it, from aboriginal skeletons to historical objects. When archaeologists and the larger body of scientists across the world are prevented from examining such materials from the past, there is reason to believe that it will similarly deprive future generations of knowing and understanding the past.The greatest threat is when these objects eventually get buried in time, forgotten and never to be seen again; the result is catastrophic because humanity will have no r eason to mount attempts to study human history. James Chatters also writes that most of the analyses and interpretations about â€Å"the peopling of America† and â€Å"where the immigrants came from† are â€Å"limited by the tiny sample of ancient skeletal material† (Chatters, p. 291).Thus, scientists should not be deprived of studying ancient skeletal materials once they are found. The more objects we can study, the more we can unveil a hidden history and the more we can know and explain how human civilization has evolved. Cultural concerns should not be abandoned, yet the primacy of scientific study should also compel us to at least suspend our ethical judgments for a moment and allow science to aid us understand our world.Bibliography Chatters, James C. â€Å"The Recovery and First Analysis of an Early Holocene Human Skeleton from Kennewick, Washington. † American Antiquity 65. 2 (2000): 291-316.

The question is this: How can we distinguish between the environmental causes of behavior (the influence of parents, siblings, family, friends, schooling, nutrition, and all the other experiences to which a child is exposed) and hereditary causes (those based on the genetic makeup of an individual that influence growth and development throughout life)? This question embodies the nature–nurture issue. In this context, nature refers to hereditary factors, and nurture to environmental influences. Although the question was first posed as a nature-versus-nurture issue, developmental psychologists today agree that both nature Gerald Levey and Mark Newman 282 Chapter 8 development and nurture interact to produce specific developmental patterns and outDevelopmental psychology The comes. Consequently, the question has evolved into How and to what degree branch of psychology that studies the do environment and heredity both produce their effects?

Despite their differences over theory, developmental psychologists concur on some points. They agree that genetic factors not only provide the potential for specific behaviors or traits to emerge, but also place limitations on the emergence of such behavior or traits. For instance, heredity defines people’s general level of intelligence, setting an upper limit that—regardless of the quality of the environment—people cannot exceed. Heredity also places limits on physical abilities; humans simply cannot run at a speed of 60 miles an hour, nor will they grow as tall as 10 feet, no matter what the quality of their environment (Dodge, 2004; Pinker, 2004). Figure 1 lists some of the characteristics most affected by heredity. As you consider these items, it is important to keep in mind that these characteristics are not entirely determined by heredity, for environmental factors also play a role. Developmental psychologists also agree that in most instances environmental factors play a critical role in enabling people to reach the potential capabilities that their genetic background makes possible.

Case Analysis of Rogers Chocolates Essay

There are multiple issues facing Rogers’ Chocolates. Rogers’ has a dated value proposition. In order to expand they need to compromise the history behind the brand. The service tactics and packaging is old fashioned. The need for a different look was further backed by a consultant hired by Rogers’. Their current traditions may be well received in Victoria but they aren’t working to fully expand markets. Rogers’ brand image was tarnished due to the import of raw materials from West Africa. West Africa was faced with issues of forced labor and child labor used in the production of cocoa beans. In Victoria, matters concerning the social and community environment were important to consumers. This poor brand image had forced some consumers to switch brands. Although one cannot make every consumer happy, it is best to keep an appealing imagine in the media. The company had issues keeping track of demand, supply and the production of chocolate on an annual basis. This created issues with inventory. Production was also slowed, due to the daily setup and equipment. Production was one shift daily and it was very labor intensive. Rogers’ also had issues with demand forecasting as it was difficult to track due to seasonality of sales. Rogers’ product had a shelf life of 6 months but smaller wholesalers were selling expired products, another area where the supply to wholesalers should be tracked. Another key issue with Rogers’ was the market they served. Since Rogers’ relied on serving a niche affluent segment of the market who sought luxury and supreme quality, they lost consumers. Their premium price point scared consumers and wholesale accounts away. The consumers of Rogers’ were also tourists who were steadily declining. Rogers’ Chocolates was also experiencing the decline in its foreign consumer base, as the ratio of tourists visiting Victoria had declined over the years. Recommendations Rogers’ Chocolates has to target the younger market and update the design of its packaging, for some of the items. They should use flashier tins and wrappers to gear to those consumers outside of Victoria. However, they should maintain what works for consumers in Victoria. They should take advantage of social media which is less costly as compared to other means of  advertising to lure in new consumers. This will boost sales and revenue. They need to increase brand awareness and reach out to a greater number of consumers through electronic or print advertisement. Television advertisement should also be used in a larger scope. They need to communicate to consumers about what they are doing to play their part in the community. Rogers’ should go public on what are they doing to promote themselves in the realm of social responsibility. Rogers’ should tie the community into charity events to create brand awareness. They need to improve consumers’ thoughts about their brand due to the issues in West Africa. They need to adopt effective public relations avenues as a means of promoting the positive image of the brand. Sam’s Deli needs a clearer vision, better management and more recruitment. They need to decide whether franchising would be a viable and profitable option. Rogers’ should also add a section of Rogers’ chocolates at Sam’s Deli so that the visitors to the restaurant may also purchase the assortment, which could secure new loyal consumers. They should provide free chocolate samples at Sam’s as a marketing ploy. Rogers’ production needs improvement. They need to establish effective tools to forecast changes in the consumer’s demand of chocolate in the local market, and match the production accordingly to avoid extra expenses and excessive waste. They should consider adding more shifts. This will put further stress on recruiting better workers, however it will make them more efficient. Rogers’ should adopt better opening, closing and cleaning procedures. They should look into the costs behind mechanical production vs hand made. This can potentially make them more efficient as well. All this should be done without compromising quality. They should consider offering a more price friendly product vs high price point to open the market up to those who aren’t affluent but still will pay for quality chocolates. In their retail stores they should continue creating a positive image of the brand in the mind of the visitors. They should also continue to create strong brand loyalty and continue to market themselves as a unique gift item which can be given to others. Porters Model Threat of New Entrants The growth rate in the chocolate industry is falling, which makes the threat of new entrants low. However, the traditional manufacturers are moving toward premium chocolate in an effort to maintain significant profit margins. This makes a moderate threat of entrants. They are doing this through market acquisitions or up marketing. There is also a greater profit margin in case of premium chocolate which makes it a more attractive tactic for the new entrants. Bargaining Power of Consumers Consumers have a moderate level of bargaining power. The loyal Rogers’ consumers dictate the packaging and store experience. Rogers’ has held onto this traditional view for their consumers. Consumers will pay the higher price because they value Rogers’ and will not switch brands. Bargaining Power of Suppliers The suppliers have moderate level of bargaining power. Consumers wanted healthier options but Rogers couldn’t gain any support from suppliers to be a part of its organic or fair trade plan of action. Threat of Substitute products and services The substitute products can be any other non-premium chocolate bar, chocolate products or candy. There are many different chocolate products available and most are an easy to find. There are about 20 options at close reach in the checkout line at the grocery store. Chocolate is readily available and this is a large threat. Most will take advantage of that availability. There are also other services available; there may be smaller private chocolatier companies that play a role in substitute products. Intensity of Rivalry among competitors in an industry The chocolate industry has a high level of competitive rivalry. There were many organizations manufacturing and selling high quality premium chocolate including Godiva, Bernard, Callebert, Lindt and Purdy’s. The competitors were making efforts to gain a larger market share through offering high quality products, but they had more affordable prices in comparison to Rogers’. SWOT Analysis Rogers’ Strengths †¢High pre-Christmas sales. †¢Premium ice cream. †¢Loyal consumers. †¢High quality, luxurious brand image. †¢Market penetration through various outlets retail, wholesale, online mail and phone orders. Sam’s Deli playing a significant role in the sales and profitability of the chocolate sold by the company. †¢The retail store run by the company was capable of creating a positive image of the brand. †¢Viral marketing more effectively. †¢Internet as a source of marketing, with high quality websites that were easy to use. Rogers’ Weaknesses †¢The company had issues in case of keeping a record of demand, supply and production of chocolate on an annual basis, which inevitably resulted in inventory issues. †¢Poor community outreach. †¢Inefficient daily processes. Opportunities Rogers’ has the option to penetrate more locations outside of Victoria with better media coverage and advertising. †¢The can produce more if they streamline their production process, which will avoid inventory shortages. †¢Rogers’ can look into acquisitions or up marketing also to better position themselves in the market. Threats †¢Godiva, Bernard, Callebert, Lindt and Purdy’s. †¢Competitors were making efforts to gain a larger market share through offering high quality products, but they had more affordable prices. †¢Substitute products †¢Multiple chocolate manufacturers not listed, ie Nestle, Hershey etc.

Impact of the Internet on Thinking by Alan Greenblatt Essay

Impact of the Internet on Thinking by Alan Greenblatt - Essay Example This paper illustrates that researchers have studied and expressed views on social, psychological, intellectual and physiological perspectives that are summarised and quoted in this report. Greenblatt begins his survey giving examples of instances of the impact of Internet use as a pervasive and addictive influence on people’s lives. Although the compulsive use of electronic media is quite unlike an addiction to chemical substances, China and South Korea already recognize it as a public health concern. Greenblatt quotes Nicholas Carr as expressing concern that the Internet can have ‘bad effects on our brains’. Jonah Lehrer argues that such ‘concerns are overstated.’ Research by the Pew Internet & American Life Project found the majority of technology experts disagreeing with Carr, who held varied opinions on the merits of the Internet. One interesting finding was that some believed that it helped create a â€Å"hive brain† enabling ‘peopl e to share thoughts and come to collective solutions to complex problems’. Robert Thompson is concerned that the ‘flood of information’ leaves people no ‘time for contemplation’ and ‘deeper reflection’. Paul Saffo says that video games ‘stimulates and strengthens parts of the brain’, but worries that such technology ‘causes ... people to... concentrate on the immediate at the expense of the long-term’... Elias Aboujaoude cites an increase in attention deficit disorder, though this may not be directly related to Internet use. However, he is certain that ‘those who spend a lot of time online have shorter attention spans’. The conclusion to this section is that with increasing availability of electronic media, the responsibility is on the individual to choose wisely as to how much time to spend on the Internet. Greenblatt points to historical resistance to new inventions leading to improved communicati on from the time of Socrates. The 15th-century invention of printing, and more recently the telegraph, the telephone and the postal service, all raised concerns, but the world has embraced and accommodated to such changes. Greenblatt explores the current situation and says that the Internet has ‘not finished evolving yet’, and forecasts that in the future people would learn to ‘disconnect’ from the Web. He concludes by quoting Aboujaoude as pessimistic about our capacity to understand the effects of the Internet ‘on our brains’, while Levy postulates two possible scenarios for the future. Either ‘we slow down and better modulate all this’ or ‘we adapt to these changes’ adding that we may not be ‘at the limit’ yet. The three basic questions that intellectuals and social critics have posed are: 1) Is the Internet making us smarter or stupid? 2) Is it addictive? 3) Does it affect our attention span? These que stions are dealt with above. 1) Carr (for) vs. Lehrer (against); 2) Aboujaoude (for) vs. Rainie (Pew Internet & American Life Project) (against); 3) Gentile (for) vs. O’Reilly (against).

The outcomes of this program are based on both cost effective perspective and cost benefit perspective. Under the cost effective perspective ,the aim of the program is to sensitize those that are trying to battle with alcohol or drug abuse and those who are fearing or do not want to deal with this problem in their lives, under this program the organization does not intent to benefit from the program either directly or indirectly but rather it aims to change the lives of those who are affected by this problem, by investing its financial resources in various programs that are geared towards assisting the affected people. The outcomes of the financial investments in the programs are usually measured against the responses and the effectiveness of the programs i.e. the ratio of change against its effects in the programs. Also ,the aim of this organization is to evaluate the impact of the awareness against what they have invested in the awareness and the result that are obtained may be us ed to help or benefit other organizations or communities(Brent ,2003 ) at the button on their website (get help now) assists them to measure the response against the investment in the program hence though this ,the organization is able to tell how people are responding to their campaigns and the statistics may be used for future reference (Levin, & McEwan ,2000).This program has been able to help most military men and women who are coming out of their work to be able to adjust to the outside live and not to turn to drug and alcohol abuse as their consolation. Some of the services offered to the military by the organization include; guidance and counseling where the programs aim is to advice those living the military on how to accept the outside world away from the military duties, and educate them on the challenges

Importance of Oral Health in a Child Essay Example | Topics and Well Written Essays - 500 words

Importance of Oral Health in a Child - Essay Example Although the accidental cause due to injury or abrasion could not be controlled, tooth decay could be prohibited and avoided. The care for primary teeth has not given emphasis because of the fact that primary teeth are just temporary and will be replaced later by permanent teeth. For this reason, tooth decay among children is not new. Bacterial respiration or acids from the diet could cause tooth decay in children. The oral hygiene and care, and diet of the child could highly influence the rate and occurrence of tooth decay. Mahoney and Kilpatrick stated that oral medications such as mouthwash and toothpaste affect the rate of tooth decay. The high acidity and the presence of EDTA (ethylenediaminetetraacetic acid), which is known as dematerializing agent, in mouthwash makes the mouthwash a possible cause of tooth wear. Their study also showed that the low pH of medicine such as asthma medicine of children increased tooth wear. Furthermore, they mentioned that the abrasion caused by brushing of teeth followed by intake of relatively acidic beverages showed an increase rate of tooth decay. According to Marsh all et al., there are high occurrences of tooth caries to children who have frequent consumption of soda pops as compared to milk and 100% pure fruit juice.

Economic development - Essay Example However, the lower half of the isoquant is continuous reflecting that the given total output level can be achieved at all combinations of inputs provided 1st world inputs are used lower than a certain level (X2*) and the intensity of using 3rd world inputs is greater than a certain level (X1*). This situation can be interpreted as a depiction of the fact that instead of combining a greater amount of first world inputs which presumably can be interpreted as the magnitude of aid, if a lesser amount of such inputs are used in tandem with relatively higher amounts of 3rd world inputs, the possibility of attaining a certain amount of global output increases. This has a close semblance to Easterly’s idea that instead of providing huge lump sum aids to poorer nations, smaller piecemeal transfers that actually generate incentives for the population in such nations to become efficient in their participations lead to increased national incomes for such nations. For instance, Easterly cites the example of free provision of mosquito nets to prevent malaria in poor nations. He points out that not only does this create a black market for such nets; the nets are diverted into other uses. On the other hand, it is shown that through charging a miniscule amount for providing the nets, proper utilization has been increased thereby implying such low price provisions to be better solutions. He also cites the example of patients fully utilizing doctors’ services in cases they have to pay for them rather than when the services have been provided freely. Therefore, the transfer of any arbitrary amount of aid, financial or in kind actually may not lead to higher incomes, a situation reflected in the dashed segment of the isoquant where these aids, as inputs combined with third world inputs fail to yield any output in the disjoint portions. The better option is thus to use a ‘search’ strategy to locate the amounts of 1st world inputs that combined with a given amounts of 3rd

Written Review - Essay Example On the contrary, an association with increased risk of breast cancer has been discovered. HRT could still be used for post-menopause syndromes. Nevertheless, it should not be used as primary prevention for CVDs and bone density diseases. Women’s health is considered to be one of the most crucial medical topics today. Such is why treatments of post menopausal conditions of women continue to be a topic largely investigated. Hormone replacement therapy (HRT) is noted to be widely used among the more developed countries (Nelson, 2008). In the United States, about one third of their population of women report to be users of HRT (Sharma, 2003). In this paper, the author aims to present the advantages and disadvantages of HRT. A review of 3 scientific medical journals will be presented and thoroughly appraised for its validity and reliability. The author hopes that by doing such, a clearer understanding of the benefits and risks of HRT will be achieved. According to Sharma (2003), hormone replacement therapy is widely used by women today because of its ability to treat symptoms of menopause and the chronic conditions associated with it. In his paper, Hormone Replacement Therapy in Menopause: Current concerns and considerations (Sharma, 2003), he launched into an in-depth critical analysis of past studies concerning HRT. His methodology involved a highly specific Medline research for papers written and submitted in the years 1997 to 2003. Only those written in the English language and have an abstract readily available were included in his study (Sharma, 2003). The specific key words used for his study involved hormone replacement therapy, estrogen replacement therapy, menopause and hormone replacement. He was also very thorough and set a criterion in which he would only include materials that are original. According to Sharma (2003) the use of HRT has a strong correlated effect on vasomotor symptoms.

Bohol, in the Eyes of a First-Time Beholder Essay Example for Free

Bohol, in the Eyes of a First-Time Beholder Essay Perched on a very young palm tree, the tarsier fidgeted as I aimed my camera on its direction. It was only a few centimeters away, so easy to touch and yet I reminded myself to avoid the temptation. I read in an article how traumatizing it can be for these velvety creatures to be held, that they would hurt themselves to death after being â€Å"violated† by curious tourists who are never content with taking pictures. So imagine my surprise when it landed very near me to catch the cricket hiding behind the leaves. Without even thinking, I brushed my fingers on its brown fur in what seemed to be a second or two; it didn’t flinch, but the click of the camera (there was no flash since it was daytime) alerted it, and it darted back to its highest hiding place in the palm tree. Like that unlikely encounter with the tarsier, my trip to Bohol was something worthy to remember. Thanks to the invitation of a friend, poet and journalist Michael Ortega Ligalig, my memory of Bohol was not limited to beaches, Chocolate Hills, and yes, tarsiers. But there is no denying that Bohol is teeming with natural and man-made assets. If you are artsy and into culture, Bohol can offer you a lot with its cultural and historical riches. If you are into nature and adventure, there are surprises that the island can offer. Churches and Heritage Houses For somebody like me who is fascinated with old things and history, Bohol is like a gold mine with its old churches and heritage houses. Almost all of the 47 towns have old, massive, stone churches that have survived natural ravages, wars and even climate change. I asked to be brought to some of the most fascinating ones, like the Baclayon and Loboc churches. The Church of the Immaculate Conception or the Baclayon Church is one of the country’s oldest churches. First built in 1595, the Jesuit frailes built the Neoclassic structure piece by piece using adobe and coral that were joined together by adhesive made from egg whites (imagine all the chicken eggs used to build such a magnificent structure!). From the front door, one could see the marble tombstones that were embedded on the walls and pylons, the names of the dead intricately written in Spanish. The retablo or the church altar was also an imposing piece of art, though we were unable to see the church’s pipe organ. It also has a museum similar to that of San Agustin in Intramuros. The fee is not very expensive, but cameras are not allowed. Still, one can take pictures of the saints on the ground floor joining the museum and the church, where they kept a coterie of human-size religious images or statues. St. Peter Parish Church or Loboc Church is the second oldest church in Bohol. Originally built in 1602, a stronger one was built in 1638. Located near the famous Loboc River cruise, it has survived a number of floods. Inside the church, murals depicting religious events can be found on the dome right on top of the main altar. A Spanish coat-of-arms can be found near the entrance of the convent which today houses the Museo de Loboc. This museum houses a few religious images and artifacts, like registry books from the 1800s and choir books. There is also a magnificent bell tower adjacent the church. One can also find a bridge that was never completed; it would have joined the two parts of the town separated by the river, but it would mean demolishing part of the church. It is also the home of the famous Loboc Children’s Choir. There are also plenty of heritage houses all over Bohol, particularly in Baclayon and Dauis. Owned mostly by merchant families and old political clans, its interiors are characterized by wide and thick wooden floor planks and wide stairways with wooden balusters. The interiors often feature wooden sala and table sets, cabinets and dressers and rocking chairs, while the walls often hold portraits of its departed residents. Some of the houses include the ancestral houses of the Clarin, Villamor, Malon, Luza, Sofia and Abueva, and some of them actually accommodate tourists for a bed-and-breakfast experience. Beaches and Diving Bohol is getting its fair share of tourism fame with its pristine white sand beaches, the most famous of which is Panglao Island and Dauis, although there are plenty of other beaches minus the flock of tourists and expensive. The most famous is Alona Beach, an 800-meter stretch of white powdery sand located south of Panglao Island. Many full-service beach and dive resorts reside there. The sea around Pamilacan Island is frequented by whales and dolphins, as it is also a favored breeding and feeding site of tuna, snappers, groupers, mackerel and surgeonfish, making it a perfect spot for those who want to see the teeming natural fish population at work. There are a number of diving spots that offer priceless views of the sea beneath. Balicasag is known for its rare, beautiful seashells and its beds of corals are considered one of the best dive spots in the country. On the other hand, Danajon Bank is the only double barrier reef in the Philippines and is one of only three such sites in the Asia-Pacific region, spread across almost 130 kilometers of seabed and consist of three large reefs. Flora and Fauna Because of its geographical features, Bohol’s endemic flora and fauna makes it a hot spot for nature lovers. The Philippine Tarsier Sanctuary in Corella town is a 134-hectare land that has been set aside as a protected area for its most celebrated creature considered the world’s smallest primate. However, there are many mini-â€Å"tarsier zoos† that are maintained by resorts. These resorts or mini-zoos often put these tarsiers in small cages and crowded, considering the wild nature of these animals. While my friend assured me that these resorts have â€Å"adoption certificates† from the local environmental offices, I still find it disturbing to find these magnificent creatures caged like birds. In the town of Albuquerque, there is a mini-zoo that claims to hold the biggest python in captivity ever known. Its name is Prony, approximately almost 30 feet and an estimated weight of about 300 kilograms. They also have a variety of birds species like parakeets, pigeons and other avians. However, a star attraction would be the entertainer which we humorously call â€Å"Kakambal ni Prony.† Clad in shiny gaudy costumes, she would dance near the snake’s spectators. We were also fortunate to visit the Mahogany Man-Made Forest in the town of Bilar, a two-kilometer stretch of densely planted mahogany trees located in the border of Loboc and Bilar. River Cruises The ultimate part of our trip would be the scenic Loboc River Cruise. We took the nighttime cruise as my friend advised because of the lamps that would light up as our boat would pass by. The boat fee includes a buffet meal that included seafood, meat and desserts. As the boat commenced its trip, a man with his electric guitar started to sing, his repertoire including American hits from the seventies. My companions and I found the lineup rather distracting as he started with Don McLean’s Vincent then to assorted songs from Bread and Air Supply. However, as the colored lamp posts began glowing from the sides, we were already transfixed and astonished. We briefly stopped on a floating raft that has a big group of singers belting their original songs. We all got off and started clapping. I interviewed some of the children and the adults who actually make a living from the song and dance number, and it ended with them selling their very own musical CD to the tourists. The visit to Bohol was short and partly fulfilling. I am decided to pursue this island more and look forward to seeing more of its assets very, very soon.

The findings were that this airport should use a combination of infrared heating and antifreeze spraying in order to deice aircraft in a fast, safe, cost effective and environmentally friendly way. The de-icing process is called the drive through method and this report has backed up its investigation through detailed calculations and the use of a decision matrix to compare the benefits of the drive through method against using others. Although there are some problems such as its relatively long payback time of 2.5 years, plus risk the airport may have to pay licence fees due to patents on the technology, the benefits of the drive through method outweigh these drawbacks. One reason for this is that after the payback period the airport will make an annual saving of approximately $7,080,000 INTRODUCTION Rationale for the research The process of removing ice, frost or snow from the surface of an aircraft is known as aircraft de-icing. This is an essential procedure because if these substances accumulate on an airplane they will amplify the drag force that the plane experiences. This will reduce the ability of its wings to produce enough lift force to allow it to take-off or manoeuvre whilst in flight. Also, damage could be caused if a large piece of ice dislodges from the plane and hits sensitive components like its engine. This could lead to passengers losing their lives in a crash and others losing their properties. The Federal Aviation Administration, FAA, regulate all major civil aviation operations in America. One of their rules is that aircraft must be free of ice before takeoff and during flight. Background This report uses Minneapolis Saint Paul (MSP) airport, Minnesota, as its primary case study. This is because aircraft at this airport frequently needs to undergo deciding as a result of the cold climate before, during and after winter in that region. MSP airport spans 3,400 acres, has five runways, five de-icing pads and served more than 32 million travellers in 2009 making it 15th in the United States and  30th in the world in terms of number of passengers served annually. (MSP Airport, 2010) De-icing is currently carried out at MSP airport by operators who spray an ethylene-glycol based aircraft de-icing fluid onto planes. Storm water drains to collect the waste fluid, before it is transported by a truck to a recycling facility to be treated. It needs treatment because its high Biochemical Oxygen Demand (BOD) makes it harmful to the environment. Research Aims and Objectives This investigation aims to find a method and chemical to use for de-icing planes which is more environmentally friendly, cheaper and faster than that which is currently used in MSP airport. It should be a total solution technology which eliminates/reduces all the problems that the current de-icing method causes without producing detrimental side effects. These aims will be achieved by completing the following objectives: Identify a substitute de-icing fluid which has the same/better de-icing functionality but costs less and is safer than the one currently used in MSP airport. Find a better way to recycle the waste de-icing fluid Ensure that the new substitute chemical allow de-icing fluid to be recycled Find another way to remove snow from aircraft GENERIC DESIGN PROCESS Organisations often use a generic design process as they turn a product idea into a manufactured item. Using a systematic, well organised designed process helps to reduce the research and development time that a novel product experiences. The design team for this project used a generic design process and the actions that they took at each stage are detailed below: Product Planning First the team used product planning to help make that reliable and valid research was carried out straight away. This started this by withholding a discussion in which they clarified the aim and objectives of the project. Then they identified their strengths and weaknesses in relation to these objectives to help them choose which duties they were responsible for. Finally they agreed upon timescales in which to achieve each objective. Identification of Customer Needs Customers needs guided the teams product innovations that were found. The team held interviews with a representative from each major stakeholder group in the airline industry, such as the airline manager and spray operator, to allow them to voice their needs. This made it easier for the team to set product specifications and design a product that they would approve. Establishment of Product Specifications The customer needs were ranked in order of their importance. The rank of each need was proportional to a weighting, w, which was later used in a decision matrix. This information was used to generate product specifications which were further defined using metrics. Generation of product ideas A brainstorm was held to generate product ideas. This was useful because it encouraged the team to build ideas on top of one another. From this they saw similarities between ideas and linked some of them to define a total solution technology. Selection of product ideas A decision matrix was used to quantitatively compare the importance of each customer need in relation to the product ideas. The product with the highest score was selected for testing. Testing The total solution technology was further evaluated in terms of its performance and economic viability. Because it was very beneficial its specifications were was sent to manufactures so that they could build a prototype. Figure 1 An illustration of the generic design process Figure 1 illustrates the product design methodology which begins with product planning and ends with testing and manufacture. The dotted lines show that if one stage of the design process did not give advantageous results the team would go one or multiple stages back in order to refine their previous intentions. Then they would advance through each stage of the process again until they reached the final testing and manufacturing stage. This procedure of assessing and re-assessing product developments ensured that poor designs were eliminated or improved before they reached the testing and manufactures stage. NEEDS Various customers have an interest in aircraft de-icing operations; these individuals are referred to as stakeholders. The success of this venture will depend on how well it meets the needs of these individuals. Hence, the team evaluated each stakeholders need using an interview and ranked it according to its importance. Information Gathering The stakeholders were identified on the basis on who will pay for, sell, use and operate the de-icing technology, these included airline pilots and passengers etc. They were interviewed and their responses are summarised below. Spray operator Q1: How do you deice a plane? A container on a truck is filled with de-icing fluid which is mixed with water to a 50% concentration by volume. I sit in an enclosed cabin and heat the fluid onboard the truck to 70oC before I spray it onto the plane until all the ice melts. Airport manager Q2: How important is the BOD of a de-icing fluid? Very important, we pay the treatment works about $0.35 per US gallon and the price goes up if the BOD increases. Our airport is fined if the BOD5 discharged to the environment exceeds 900 tonnes per year. Q3: How long would you expect to wait for a return on your investment? 1.5-2 years Q4: How much does ethylene glycol cost? The average is $5-7 per gallon. Q5: What precautions were taken since your last incident? We thought of retraining staff, but now operations are run by an outsourced business. De-icing pads and a drainage system were installed. Aircraft manager Q6: What do you think of integrating a heating system onto aircraft? Not ideal for commercial planes because its expensive Air traffic controller Q7: How severe is the disruption caused by aircraft de-icing? During the peak of the winter season there are regular delays. Aircraft must be de-iced again if they exceed a holdover time of 5 minutes. Ranking of needs and sanity check The team identified the most important stakeholder needs and ranked them as listed below. Each need was given a weighting, w, according to its rank as part of a sanity check. Table 1 The rank of each stakeholder need and its weighting Need Weight-ing, w Reasons 1) Safety 4 Safety was the top concern of every stakeholder. Aircraft at MSP airport can only carry passengers if they obey safety regulations set by the FAA. 2) Lifetime Cost 3 Some stakeholders disagreed on financial issues regarding how much cash should be spent on certain items. e.g most spray operators would like luxury de-icing cabins whereas airport managers would rather invest the money. However, all stakeholders agreed that no de-icer with a high lifetime cost would be acceptable. 3) Speed 2 Slow de-icing can cause profit losses due to delayed flights. 4) Environmental impact 1 Although the airport will be fined for causing excessive pollution these costs are normally absorbed by customers. ESTABLISHMENT OF PRODUCT SPECIFICATIONS Most of the needs highlighted by stakeholders were expressed in a qualitative manner. They needed to be converted into specifications in order to avoid trivial yet expensive improvements being made to MSP airport. To do this the worst case de-icing conditions that could potentially take place at MSP airport were defined and as part of sanity check. Next metrics were used establish specifications for product and process design methods that could cope with the worst case de-icing scenarios at the airport. Specification 1 Annual length of operation The dates in which the planes will need to be de-iced ranges from November to early April because on these dates the temperature in Minneapolis Saint Paul is below freezing. Therefore, any new de-icing method must be able to operate through this period of 5 months and 1 week (157 days) every year. (Figure 2) Figure 2- The average lowest temperature in MSP every year from 1971-2000 Specifications 2 The case study aircraft and its ice coverage The mass of ice on a plane was calculated using a worst case scenario, which was that one of the biggest commercial passenger planes; the Boeing-747 (BBC, 2007) needed to be de-iced. It was assumed that the top area of both its wings was covered by a 1cm thick layer of ice. Wing area (Boeing-747) = 541.2 m2 (Airliners, 2010) Ice Thickness = 0.01m Ice Coverage 100%  Ã…“ Volume of ice on wings, Volice = 5.412 m3 (App. 1, Eqn 1) Density of ice, à Ã‚ ice = 917kg/m3 (Kotz, 2009)  Ã…“ Mass of ice, = 4962.8 kg (App. 1, Eqn 2) Specifications 3- Heating Duty Latent heat of fusion of ice= 333 kJ/Kg (Bird, 2003)  Ã…“ Minimum heating duty = 1652.6 MJ (App 1, Eqn 3) Specifications 4 The substitute de-icing fluid The atmospheric temperature in MSP airport during the de-icing season is 20oF (-29oC) therefore the substitute ADF freezing point must be less than 20oC in order to maintain its functionality. Additionally it must provide a freezing point depression of more than 20oC as a result of this ambient temperature. All the stakeholders agreed that product safety is of upmost importance, so the substitute ADF should be less toxic than ethylene-glycol. Additionally they agree that the annual raw material costs of the new dicing method should be less than that of the current method. Two ways to do this are to use less dicing fluid per plane in the first instance; this should be less than the 408 gallons per aircraft required by the current de-icing method (App. 1, Eqn. 9), or to recycle the de-icing fluid. GENERATION AND SCREENING OF IDEAS The team worked individually and brainstormed together to help maximise the number of good ideas that were generated. Whilst doing so they reflected upon the product specifications to and stakeholder needs to help screen ideas. De-icing Ideas De-icing boots Rubber boots are attached to the front edges of wings on the plane. The aircraft inflates these boots with air to cause ice that remove ice that has accumulated on them. An unacceptable risk of using this method in MSP is that the system must be activated as soon as a before an large ice layer can form and hit other parts of the plane when it dislodges. Bleed air- In this method hot air from the aircraft engines is blasted on to the ice to melt it. Although this could melt ice very quickly the airport manager at MSP airports commented that integrating heating systems on to aircraft is not ideal for commercial planes because its expensive. Mechanical Scraping/Blowing Employees use brushes, or cloths to physically push ice off the aircraft. This method would be very easy to put into practice at MSP because the equipment the required is very cheap. But it is more likely that damage will be done to airplanes as the employees scrape ice so the resulting aircraft maintenance cost is could be very high. A propylene glycol based de-icing fluid Propylene glycol is a popular de-icing fluid and is regarded as non-toxic, hence it was chosen for further investigation. Decision Matrix The interviews that were conducted with the stakeholders highlighted that some customer needs are more important than others. Although the importance of some specific needs differed in each stakeholder group four needs were consistently rated as essential. These criteria were analysed in a decision matrix with weighing marks taken from Table 1 Table 2- Decision Matrix which focuses on the alternative deinking methods ALTERNATIVES Ethylene Glycol (Benchmark)   Propylene Glycol Infrared + Propylene-glycol Criteria Weighting w Rating Score Rating Score Rating Score Safety   5 2 10 4 20 7 35 Lifetime Cost   4 5 20 5 20 6 24 Speed   3   5 15   4 16 6 18 Environmental impact   2   1 2   5 10 6 14 Total   14   13 47   18 66   25 91 According to this decision matrix the best de-icing solution should be based on a combination of infrared and propylene glycol de-icers is the best as this alternative has the highest sore. The second best method would be to use an ADF which is based on propylene glycol rather than ethylene glycol. SELECTION OF IDEAS A comparison of ethylene-glycol and propylene glycol based de-icing fluids The most freezing point depressants in aircraft de-icing fluids in the US are ethylene glycol (EG) and propylene glycol (PG). Because PG and EG have a similar lifetime cost, in this chapter the chemicals will be compared at a 50% concentration by volume in terms of their safety, de-icing speed and environmental impact because these are three of the most important needs the stakeholders. Safety Ethylene glycol has a relatively high toxicity when compared to Propylene-Glycol. It has been classed by the US congress as a hazardous air pollutant (HAP), if 2268 kg or more escapes into the environment within 24 hours users are obligated to report the event under the Comprehensive Environmental Response Compensation and Liability Act (CERCL). However propylene glycol is not classified as a HAP, and users are not required to inform CERCL if it is released. Both chemicals are said to be non-lethal if humans if they are breathed in with air or adsorbed through skin. However, unlike PG, EG is toxic to humans and mammals if it is ingested directly. Even though PG it is regarded as non-toxic it is still a health hazard because it uses oxygen as it biodegrades which could cause some organisms to suffocate. De-icing Speed The freezing point of Propylene-glycol is -34oC which is slightly higher than ethylene-glycol which freezes at -37oC. This is one of the reasons why MSP airport still uses EG. Another is that a lower volume of antifreeze is required for EG to achieve the same freezing point depression as PG. MSP airport suffers severe weather extremes so it needs to use an ADF which is reliable, especially in extremely cold weather as this is generally when it takes longer to deice aircraft Propylene-glycols boiling point is 106oC whereas ethylene glycol has a boiling point of 102.2oC for ethylene glycol. In this case Propylene-glycol is the better choice because it can transfer heat to ice at a higher temperature than ethylene glycol. Discussion There are some drawbacks with regard to using ethylene glycol as a de-icing fluid, especially concerning its environmental impact. But, overall EG and PG have a similar de-icing performance level. The Rate of Melting due to Heat Conduction Alone The ADF is heated to 70oC before it is sprayed onto the plane, this heat alone will cause the ice to melt through heat conduction. The rate of this heating was calculated using equation 1a, 1a) Where Q= is the heat flow rate in the X-direction in kJ/s, A is the area normal to the direction of heat flow in m2, dT/dx is the temperature gradient and K is the thermal conductivity of ice The thermal conductivity of ice at -20oC is 2.39 W/mK, the area normal to the direction of heat flow is equal to the wing area of the Boeing 747 =541.2m2, the temperature change that occurs is (70oC- -20oc)=90oC and the thickness of the ice x is 0.01m. Hence the rate of heat transfer by the temperature of the de-icing fluid alone is 2a) The sensible heat is kJ (App. 1, Eqn 12) The latent heat of fusion is 1652612.4 kJ, (App.1, Eqn 3) Summing the above gives the amount of het required to melt the ice on a Boeing 747 from a starting temperature of -20oC which is Hence minimum time that it would take to melt the ice on the plane by heat conduction alone is This is a very fast time, especially as according to the project brief, de-icing at MSP airport normally takes 10 minutes per plane. One reason reason for this difference is due to the fact that the ADF fluid is not always in full contact with ice, only its bottom surface is. Additionally these calculations assume that heat transfer occurs over the whole of each wing evenly, which is not the case in real life because de-icing fluid is sprayed onto the wing in different locations systematically. A final cause of this difference could be due to the fact that snow has a lower heat conductivity, k, than ice and so any snow on a plane would lower the rate of heat transfer from the ADF. TOTAL SOLUTION TECHNOLOGY Drive-Through De-icing Figure 3 An illustration of the drive through de-icing technology The final design concept was to conduct de-icing operations as a drive through system. First the aircraft enters the Infrared hangar where and warm air blows snow of its wings whilst they are heated by infrared radiation for a typical duration of 5-10 minutes. Ice on the plane melts onto an inclined slope and the wastewater is channelled into the waste collection zone. Water is channelled through existing storm water pipes into infrastructure to the located under the floor of the spraying and waste collection area. The wastewater is pumped out and transferred by a truck into the airports detention ponds. When the wastewater has been removed compression plugs are removed and the plane moves into the spraying area. Here it is sprayed with propylene glycol for up to 5 minutes to help prevent any ice forming on it before takeoff. The propylene glycol drains into a separate area of the collection chamber and is pumped to a detention pond until it is due to be recycled. Finally the compression plus are reinstalled so the system is ready to deice another plane. Recycling Solution Minneapolis currently uses three Glycol Recovery Vehicles to collect wastewater. Using the IR facility eliminates the need to deice aircraft using glycol by around 90%, so no more of these vehicles will need to be bought if the new technology is adopted. Also the airport has saved capital costs by using their existing storm water drains to collect both glycol and storm water. These storm drains can and should continue to be used if MSP airport adopts the Drive-Through De-icing system to save cash and time during the installation of the new system. According to (Big book) Careful management of the retention systems enables the airport to collect enough wastewater with high glycol concentrations to make glycol recycling/recovery economically viable. The majority of glycol which is recycled is sold to manufacturers who use it in other glycol-based products. ANALYSIS OF ECONOMIC VIABLITY Rate of return on investment (ROI) 3a) Payback Time 3b) =2.5 years Unfortunately the payback time on the drive through de-icing method is not fast enough to satisfy the Airport Managers at MSP who expect a payback time of 1.5-2 years. A higher rate of return on investment would reduce the payback time so it would be wise to look into additional ways to reduce the cost of de-icing using this technology, and ways to improve its efficiency. Patent issues Because this total solution technology uses de-icing methods which have been used in industry previously, but it combines them in a unique way it is difficult to assess whether or not it can be patented. Moreover, it is expected that it would take a long time to patent the product even if it were possible because of its complexity and use of old de-icing ideas. The author has recommended that MSP airport consults a lawyer regarding these matters if they do not need to use the de-icing solution immediately. If MSP airport do need to use the technology immediately they might have to pay license fees to one or more patent owners. CONCLUSION The findings from this investigation have shown that the solution technology that MSP airport should use to improve its aircraft de-icing solution involves using infrared heating and a propylene glycol as a substitute chemical for ethylene-glycol. The process is called the drive through method and the major advantages of this hybrid solution are that it meets the needs of its stakeholders by being safe, having a low lifetime cost, fast aircraft de-icing rate and low environmental impact. Evidence of this has been provided through a decision matrix and several mathematical evaluations. Unfortunately this solution has a payback time of 2.5 years, so research should be carried out to reveal how to make the annual rate of return on the investment higher. Finally, this hybrid system uses patented technology so MSP airport might have to pay licence fees for a number of years if it used the drive through method. However, after the payback period the annual saving of $70,844,300 per year outweighs any of these drawbacks. Further Recommendations Find ways to cut the operating cost of the Drive-Through De-icing system as this will lift the annual rate of return that this technology provides. If the rate of return is high enough the payback time will drop below 2 years and the airport managers in MSP will have this need fulfilled. Use hot air to blow snow off the aircraft in the IR hangar. This will help to melt the snow and ice too, however the cost of warmin+ 3.0g air may offset the benefit of a faster de-icing time. Nb, as shown by the weightings, w, in Table 1, the lifetime cost of the technology is more important that the de-icing speed that it provides.

The amount of heat energy, Q, required to achieve this was calculated using Equation 3 (3) (Bird, 2003) Specifications 4 The substitute de-icing fluid In this section the volume of ethylene glycol and propylene glycol needed to deice a single Boeing-747 will be calculated and compared. The metrics are based upon a 50% by volume solution of each chemical. Volume of Ethylene Glycol Required The freezing point depression of an ideal solution is given by the formula (5) Where à ¢Ã‹â€ Ã¢â‚¬  Tf represents the freezing point depression, m, is the solute concentration and Kf represents the freezing point depression constant of water which is 1.86 °K ·kg/mol (Kilter P., Mosher M. and Scott A. Andrew scott, 2008) The desired freezing point depression, à ¢Ã‹â€ Ã¢â‚¬  Tf is 20oC because winter temperatures in MSP fall to that temperature, according to the project brief. (6) The number of moles of glycol required to achieve the freezing point depression: (7) The chemical formula of ethylene-glycol is CH2OHCH2OH Mr Carbon = 12, Oxygen=16, Hydrogen=1  Ã…“Mr ethylene glycol = 2*16+2*12 + 1*6= 62 g/mol Hence the mass of ethylene-glycol required per plane is: (8) The density of UCAR ADF at 20oC is 8.9 lb/gal (US) (1.07 kg/L) (SAE AMS 1424 Ethylene Glycol-Based Type I Fluids page 8) Hence the volume of ethylene-glycol required is at least 408 US gallons (9) Because the de-icing fluid used in MSP airport is 50% ethylene-glycol and about 50% water, de-icing a single plane would need double the amount of ADF which works out at 6,184 litres. The cost of ethylene glycol per aircraft In general the chemical components in de-icing fluids, such as water, have a total cost which is substantially less than that of ethylene-glycol. Hence the cost of these components in de-icing fluid solutions as deemed insignificant and ignored. According to the airport manager that was interviewed the minimum cost of a gallon of ethylene glycol is $5 per US gallon (10) In MSP airport there is an average of 293 takeoffs per day from 5 de-icing pads (MSP Airport, 2010) Assuming that during the de-icing season in MSP lasts 157 days and every plane needs to be de-iced the annual cost of ADF is approximately (11) Sensible heat required According to the project brief winter temperatures in Minneapolis Saint Paul fall to-20oC. Ice must be brought to its melting point of 0oC before it can undergo a phase change from solid to liquid. Where Cp is the specific heat capacity of ice at -20oC which is 2 kJ/kg/K, (Tsokos KA, 2010), m is the mass of ice and à ¢Ã‹â€ Ã¢â‚¬  T is the temperature difference (12) According to Wingsmagazine (2010) Ian Sharkey, the director of de-icing services, with Radiant Aviation Services stated that during an ice storm on March 15-16, 2007 his team had an average aircraft block time (aircraft brakes on to brakes off) of less than 43 minutes for large aircraft hence it was assumed that the Boeing 747 could be de-iced in this timeframe as well. This information was used to estimate the power that the IR deice would need to bring the ice on an aircraft from -15oC to 0oC in 43 minutes, (13) Latent heat required Next was calculated which is the power needed to melt the ice on the aircraft at 0oC in 47 minutes. (14) Hence the total power needed to melt ice on the aircraft in 43 minutes by using infrared deink technology, QIR is (15) To make the value of QIR more realistic some assumptions concerning the amount of energy loss, between the heat source and the wing were added. From this the extra power that the laser will need to give out in order to overcome the inferred energy lost as between the source and its destination (transport efficiency) and the energy lost due to reflection by the ice on the surface of the wing (absorption efficiency) was calculated. Laser device efficiency, ÃŽÂ ·laser=0.33, Transport efficiency, ÃŽÂ ·transport = 0.75 Absorption efficiency, ÃŽÂ ·absorbtion =0.75 The laser device, transport and absorption efficiencies reduce the amount of energy that heats the ice. This is called the efficiency loss, 1-ÃŽÂ ·i, and it was calculated as follows , (16) Hence, (17) Similarly, (18) Hence, the percentage extra energy, ,required to cover for these energy losses is (19) In real terms

Comparing the Novel and Film Versions of Elizabeth Bowen’s The Heat of the Day :: Comparison Compare Contrast Essays

Comparing the Novel and Film Versions of Elizabeth Bowen’s The Heat of the Day When reading Elizabeth Bowen’s 1949 novel, The Heat of the Day, and then, viewing the movie by the same title, large and small differences are noted. These differences are enough to make both the reading and the viewing interesting and not a boring duplication. When comparing the opening sequences, the differences are striking. Bowen’s story begins with the interaction between the mysterious Harrison and the determined woman, Louie, in Regent’s Park; the screenwriter’s version establishes all the characters and places the stories events into a chronological order that changes the impact of the scene. By discussing the opening scenes in each media it becomes apparent that Elizabeth Bowen has more faith in her audience than the screenwriter has in his. Bowen assumes that the reader is capable of comprehending the introductory scenes when written from the view of the ‘mind’s eye’. The screenwriter lacks confidence in his viewer and finds it necessary to lose the cloak and dagger impact in order to make sure the story is understood. Elizabeth Bowen’s writing is very descriptive. She takes great pains to ensure that her reader â€Å"sees† the environment in which her characters dwell as well as having a clear picture of the personalities and characteristics of each individual. In Chapter One’s opening two sentences, Bowen perfectly paints a portrait of autumn in London’s Regent’s Park. The reader’s mind easily drifts into an autumn mood and remembers fond times of his life when the leaves gently floated down from trees overhead attempting to cover the earth in a riot of color. As Chapter One continues, Bowen establishes her venue in the park describing the open-air theatre with its walled thickets and tall trees, musicians performing the music of waltzes, marches and overtures, and the varying nationalities of people in attendance, not just the English but visitors too. It is at this point that the reader first discovers the comic elements that will be hidden throughout within the perplexing story. Bowen writes, â€Å"mothers tired of being mothers forgot their children as their children forgot them – one held her baby as though it had been a doll† and then goes on to say, â€Å"these were the English† (4-5). Here is the dry tongue-in-cheek British humor that brings a quiet giggle to the surface or a smile to the face.

An Interpretation of the Ghost :: science

An Interpretation of the Ghost Ghost is something that some believe and some won't. But still most of them get frighten to some extend, when they watch terrific horror films. Perhaps it is due to the terrific sounds or special effects that imposes ones mind. But there is a specific science that has the ability to explain the concepts of the spirits or ghosts called Adhyathma (A study centered around the soul)in the Ancient Indian script. According to the teachings of the ancient scripture Bhagavad Gita, the brain (and the body in general) is only a mechanical device used by the spirit soul (the actual self). It is described that just as a passenger rides in a chariot, in the same way the spirit soul is riding in this vehicle of the body. The scriptures state that one who commits suicide will have to remain as a ghost for the period of time that one's body was supposed to exist. A ghost is nothing but a person with no physical body. According to the sankhya system, our body is made up of two coverings, the sukshma-sharira (subtle body) and the sthula-sharira (gross body). The gross body is made up of the panca-bhutas (earth, water, fire, air and ether), and the subtle body is made up of the mind (manas), intelligence (buddhi) and identification (ahankara). It is the subtle body which accompanies the soul into the next body at the time of death. The gross physical body has a particular duration of existence based on one's prarabdha karma(results of the deeds of his previous incarnation).When one commits suicide, one brings one's physical body to an end prior to it having completed it's allotted time. One's next body is prepared in the akasha (ether), ready to manifest at the end of one's allotted time (the normal death of one's physical body). Thus if one was supposed to live for 100 years, one's next body will be waiting for you after that 100 years. If for some reason one were to commit suicide at the age of 50, then one's next body will not be ready, and one will remain in an ethereal state until the balance 50 years of existence pass. This state of existing as a ghost is a great suffering for the individual, as they lack the senses through which to act. The desires to act remain, as the mind, intelligence and identification of the subtle body are still existing.

According to the teachings of the ancient scripture Bhagavad Gita, the brain (and the body in general) is only a mechanical device used by the spirit soul (the actual self). It is described that just as a passenger rides in a chariot, in the same way the spirit soul is riding in this vehicle of the body. The scriptures state that one who commits suicide will have to remain as a ghost for the period of time that one's body was supposed to exist. A ghost is nothing but a person with no physical body. According to the sankhya system, our body is made up of two coverings, the sukshma-sharira (subtle body) and the sthula-sharira (gross body). The gross body is made up of the panca-bhutas (earth, water, fire, air and ether), and the subtle body is made up of the mind (manas), intelligence (buddhi) and identification (ahankara). It is the subtle body which accompanies the soul into the next body at the time of death. The gross physical body has a particular duration of existence based on one's prarabdha karma(results of the deeds of his previous incarnation).When one commits suicide, one brings one's physical body to an end prior to it having completed it's allotted time. One's next body is prepared in the akasha (ether), ready to manifest at the end of one's allotted time (the normal death of one's physical body). Thus if one was supposed to live for 100 years, one's next body will be waiting for you after that 100 years. If for some reason one were to commit suicide at the age of 50, then one's next body will not be ready, and one will remain in an ethereal state until the balance 50 years of existence pass. This state of existing as a ghost is a great suffering for the individual, as they lack the senses through which to act. The desires to act remain, as the mind, intelligence and identification of the subtle body are still existing.

The Awakening: The Fall of Kate Chopin’s Career Essay -- Biography

Did you ever wonder what it was like for a woman to live in the 1800’s? Like in any other decade, there were many memorable events that influenced the writers of this era, but for women writers, this era was characterized by feminism and the fight for women’s rights. Writers like Kate Chopin brought most of the feminist issues to the light through books such as hers, The Awakening. Kate Chopin had a difficult childhood, in which she lost most of her family members. When she began writing, she revealed beliefs of movement of leaders about rights of women. Critics say Chopin based most of the characters in her books on leaders of the movement, on herself, and on regular women of her time. Chopin’s life was in a downward spiral until she started publishing her works of literature. After publishing The Awakening, her life progressively began looking up. Kate Chopin’s birth was in St. Louis on February 8, 1851. Five years later, she started school at the Academy of the Sacred Heart. Later on in her schooling, she found a classmate that had the same love for reading and writing as she, but not long after, she had to stop attending school for two years (Adams ix). This was because of the death of her father. Chopin was the only of her three siblings to live a long life. She lived with her widowed mother, her grandmother, and her great-grandmother (Long). Nine years later, her grandmother passed away. This was only shortly after that passing of her brother (Adams ix). When she finally went back to school, she had picked up her Cajun Uriegas 2 influence (Long). Chopin was now also a nonconformist. Her family owned slaves that she loved spending time with. She took down the union flag and hid it earning the name St. Louis’s littl... ...t 123). The Awakening shows the Creoles living in the French Quarters and how the other Creole Americans live (Hatchet 123). It also shows that the initial influence stayed strong (Hatchet 123). Kate Chopin had her share of rough times in life, but writing was her escape. She used her writing to let people know what was going on the world as far as women’s rights were concerned. The critics say that Chopin showed her rebellious attitude through her characters and the Creole influences that were apparent in her books. Kate Chopin was not a part of the women’s rights movement, but they inspired her writing in many ways. Women of this time had very few rights and what rights they had were not given up. Feminism was on the rise writers like Kate Chopin helped everyone see what women needed and deserved even though their opinions were very controversial.

On the Road Essay

Response: Chapters 1-2 From the very first pages of the book it becomes clear that the book is a novel of characters rather than a novel of plot. I think the novel captures the audience due to unexpected movements of the main characters. First chapters show that the whole plot centers on the character of Dean Moriarty. The novel starts with Sal’s descriptions of his life before Dead. He has just split up with his wife, has recovered from serious illness and, we see that he simply doesn’t know where to move and how to arrange his life. Sal seems to be weaker personality than Dean, who manages to direct Sal’s actions the way he likes. Sal feels tired and depressed and I think that he has lost sense of life. It is Dean that sparks Sal’s personality into motion. It is possible to say that Dean is personification of Sal’s dreams. Sal has always dreamed of moving to the West and Deans arrives from there. Dean lives in San Francisco, travels across the country. Dean drinks a lot, uses drugs and has many women. Moreover, he is a father of four children from two different women. In the first two chapters Kerouac juxtaposes the ideas of the East and the West. The East is presented as old, intellectual, critical, saddened and stagnant, whereas the West is presented as passionate, wild, young and exuberant. Sal and Dean are described with attributes of the places they are from. The West is a new horizon for Sal, and the East is a new horizon for Dean. The novel is told from Sal’s perspective and we are allowed only to see and to feel through Sal. In the first chapters Sal remain unchanged; he is only sparked with the idea of something new and unexplored. Sal is impressed by Dean’s impulsiveness and recklessness. I think that Sal is willing to have the same qualities as Dean, he realizes that he may change his life, to introduce something new and wild in his bored lifestyle. Response: Chapters 3-4 We see that Sal’s adventure with Dean begins. Sal is very excited as he will become acquainted with places he has never been to. Thus, his descriptions of the passing places are exuberant and vivid. I think Sal fees younger, stronger and more confident. Through the long sentences and paragraphs, Kerouac shows that Sal’s exciting feelings are constant, they are rolling in motion. Sal reminds a child who is allowed to something secret, forbidden, something he has never been allowed to do. Relative lull occurs in the Des Moines hotel, when Sal awakes in the morning and can’t understand where he is, who he is and what he is doing. He realizes he is somewhere halfway across America, between the East and West. I think Sal realizes he is halfway from his long-awaited dream. Sal’s emotions are paralleled with surrounding geography. Through geography Sal manages to provide his emotions, ideas and dreams with definite forms. Sal’s emotions are changing and geography is changing as well. Interestingly, Sal feels when approaching the west everything is better and bigger. Even the ice cream and apple pie are testier. All the characters Sal meets on the road are individuals, they are epitomes of the region, embodiments of better living standards. To signify all events and characters, Sal describes everything in superlatives – the best, the prettiest, the hugest, etc. It shows that he is really fascinated with his journey and really obsessed with the West. For Sal, Denver is the Promised Land, Nebraska resembles the Nile Valley, and San Francisco is the greatest among them. Sal visits Denver, where Dean was born. Again Sal thinks Dean is envisioning the West. These chapters are the climax of Sal’s compassion, excitement and clear-eyed tolerance. We see Sal simply follows Dean in everything; he even reshapes his values and beliefs. Response: Chapters 5-6 Sal’s adventure with Dean continues: new impressions, new acquaintances, new ideas and new dreams. Sal realizes that the West is approaching, and he feels more confident that his dream will come true. Nevertheless, we see that Sal remains modest about himself, although he envisions place and people in grand terms. Sal is constantly pleased, and, at the same time, he seems not to believe that he may approach the West. He has been dreaming of the West for many years, and I think it is difficult for him to understand that his dream may be accomplished. He is thankful to Dean for opportunity of self-expression and self-realization. In my opinion, I can’t say that Dean is positive character. Yes, he has influenced Sal showing him new opportunities and new horizons, but Dean is too wild and mad. Sal didn’t understand yet possible outcomes of their so-called friendship. Dean is zealous and wild personality, though he is captivating as well. And his wildness and craziness attracts Sal who used to live a calm life. Sal begins picturing himself in the eyes of his new friends. He stumbles into Denver considering the city mysterious. Nonetheless, we know that Sal is too earnest and infatuated to affect something or someone. Sal is the person who is affected, not the one who affects. Despite Sal is with his friends, he feels less- confident. When he gives a cryptic answer, he is criticized and, instead of defending his position, he explains that he doesn’t know what they try to get at. In these chapters Kerouac shows that Sal is more an observer rather than performer. He faces new world and he doesn’t know how to cope with it, how to behave, what to expect from it. I think that the majority of Sal’s idealistic visions are nothing more than facades, and in future they will definitely result in sadness and disillusionment. However, Sal is mot aware of that fact.
