HD-DVD vs. BLU-RAY Essay Example | Topics and Well Written Essays - 1750 words

HD-DVD vs. BLU-RAY - Essay Example Weaknesses are happening on a couple of fronts. On the content development front, the DVD authoring front, we continue to see extreme price pressure in authoring services. The price of DVD authoring software has come down. The fact that more and more people are doing it puts incredible pressure on the production community to develop a quality product that is certifiable over all of the various players, delivers the same experience to the customer, and builds and maintains margins in their production services. (Sweeting, 2004, p7-46) On the other side, when we look at the next generation high definition DVD disc, which will certainly be all the rage in 2006, a weakness there is how soon the consumer will embrace this technology, particularly if there are two formats. As we all know, DVD was the most successful consumer product ever launched, but if you look at it now, most people have DVD players and are very content with the experience that they get in watching DVDs in their home. How quickly will they want to purchase a more expensive DVD player to play high definition material is something everyone is grappling with right now. (Capps, 2005) It is likely that moving forward the next wave [of opportunity] will fall to special interest categories and even corporate video--outreach and recruiting applications. Certainly, the opportunities for DVD in 2006 are tremendous. Beyond the applications in the corporate, marketing and outreach programs, we'll see special niche DVDs having greater acceptance. Then, of course, we have the whole next-generation issue, which hopefully will come to the forefront in 2006. The threat, especially for high definition, will definitely be how quickly the consumer will embrace that technology, particularly if there are two competing formats. You'll also have, on another front, a continuing piracy concern. That will bring pressure on studios and on the production community to figure out ways to safeguard the transmission of the information and the actual content on the DVD. We will see more movies being released more quickly to DVD. We will see the continued growth of TV programming and music on DVD, We will see the emerging market of 'special interest' DVDs [from educational, travel, marketing, outreach, recruiting, etc.]. And of course we will see the next generation of DVDs, in high definition.Blu Ray will win the high definition DVD arms race, but my guess is that it will take some time for the 75 percent of households who already own a standard definition DVD player to slowly warm up to parting with the cash to upgrade. In all likelihood the adoption wi ll be much slower than standard DVD. The entire industry is holding off until March to launch both formats [DVD HD and Blu Ray]. So we won't be able to see until March of this year how well the fall of this year will be. Also, how fast will HD disc formats be adopted by consumers It took four years for consumers to adopt DVD; will it take six years to get them over to HD We don't really know. (Laser Focus World, 2004. p11-11) A cross-industry debate over the next-generation high-definition optical-disk format turned uglier after Microsoft and Intel publicly backed the HD-DVD standard over its Blu-ray rival. Moving beyond the turf war talk of whether PCs or consumer electronics will rule the digital living room, the HD-DVD vs. Blu-ray battle

Theology second paper Essay Example | Topics and Well Written Essays - 750 words

Theology second paper - Essay Example It requires them to make reference from the Bible for their daily mannerisms. The belief in Jesus Christ also negotiates their reactions towards the modern society (Moore, 2). The modern society engrosses diverse challenges brought by technology and social dynamics. Therefore, Christians respond to the contemporary social situations in reference with their affiliation with Jesus Christ. Jesus’ death for everyone in the world exhibited his unconditional love. Through this act, Jesus demonstrated equal attention of each person regardless of their originality and background. The modern society is experiencing pronounced inequalities towards particular people and groups (Chopp, 3). Social stratification is an evident phenomenon across the modern society. This challenge requires the Christians to respond in a particular manner. They ought to respond in their belief towards the nature of Jesus Christ. They ought to make a reference to the manifestation of Christ’s love at the cross. He died for each person regardless of their background and originality. The book of I Corinthians 15:1-5 demonstrates the essence of Christ’s death for the human race. It clearly reveals that Christ died for each individual in society (Hanson, 22). Upon observation of Christ’s unconditional love that is free from discrimination, Christians ought to express the same in the modern society. Therefore, this move will entail embracing all the differences amongst the people in society and expressing unconditional love towards them. The contemporary American society has manifested intense levels of discrimination. Persons are highly discriminated and deprived of their rights according to their backgrounds (Chopp, 3). America is a society that entails diverse personalities with unique backgrounds. Within this society, there are immigrants as well as white natives. The key challenge in this society is the persistent antagonism amongst the ethnic clusters. Immigrant

EMMA LARKINS FINDING GEORGE ORWELL IN BURMA Essay

EMMA LARKINS FINDING GEORGE ORWELL IN BURMA - Essay Example The army heightened a state of lawlessness that denied and extorted the people’s little resources to fulfil their political responsibility and unsustainable democracy in their society. The military government of Burma has showed similarities with the British colonial government in many ways for example it led to split of allegiances among different ethnic groups and also between the indigenous people of Burma (Larkin, 2011).  Also ethnic minorities were not allowed to acceses land, it also resulted to religious conflicts between the muslims, budhist, hindus and Christians in Burma. Their was aslo displacement of citizen both inside and outside Burma. Besides forced labour by the military has also been expirieced which has led to the human rights violation as well as explotaiton of the minority goups. Some of the tools used by post colonial government of Burma was one the tgroup identity where the minority were given the priority to manage local properties and istitutions. secondly rebellion rebellion was employed where the minority were rqruited into the police army surpressing the majority Burman. Thirdly the nationalist tool was used where the Burmese language and ethnicity was emphasized because of the cultural and religious diversity of Burman. The fear to loose power as suggested by Aug snag suu kyi led to all injustices of human right violation, ethnicity,forced labour and so on in Burman. Leaving Burma alone fear has been employed in many countries for example employees who advocate for their rights are threatened to be arrested hence they fear and step down.

Carrefour A French Multinational Retailer Marketing Essay

Carrefour A French Multinational Retailer Marketing Essay Introduction Carrefour, a French multinational retailer, was establised by the Fournier and Defforey families as a supermarket in 1959. In 1963, new concept hypermarket, was discovered and invested. Since then, Carrefour owned up to 5,200 stores worldwide, reaching out to 26 countires and region (refer to appendix A). In particular, for Asia, Carrefour have invested in China, Taiwan, Malaysia, Indonesia, India as well as Singapore with approximately 361 hypermarkets, 17 supermarkets and 2 other formats of stores (refer to appendix B). Opening its first store in 1997, Carrefour was the first to introduce hypermarket concept in Singapore, where everything can be purchased under one roof (aisaone business 2012; Krishnan 2012). Oxford dictionaries (online) defines hypermarket as a very large self-service store with a wide range of goods and a large carpark typically situated outside a town. Carrefour had two stores in Singapore; Suntec City and Plaza Singapura. Subsequently, in 2000, Giant, a major hypermarket retailer, joined the market, competing with Carrefour. As a result, Carrefour was not progressing well. Reported by numerous news (refer to appendix C), in a press release on 28 August 2011, Carrefour announced the decision to close its two stores in Singapore by the end of 2012. This decision was reached because Carrefour realized that there is no expansion and growth prospect in Singapore that brings them to a leadership position in the long term. Marketing Problem Segmentation/ Customer Research For 15 years, Carrefour has been providing consumers with one-stop service but it did not turn out as expected. Concluded by Krishnan (2012), Carrefour came in with the mind-set that consumers in Singapore would avoid frequent shopping and hence, would buy as much as possible within a trip. Unfortunately, this prediction was not accurate as this behaviour was not seen popular in Singapore. In addition, both Carrefours outlet was located in central hub which in customer perspective brings significant inconvenience such as high travelling cost and traffic congestion. Moreover, Carrefour does not offer unique products that appeal to consumers, enticing them to choose Carrefour over other retailers and local grocery shops (Krishnan 2012). As a result, Carrefour was observed to be targeting at the wrong country and customer segment, facing huge hurdle in attracting consumers with their one-stop shopping proposition, location and products offered. Sales and Distribution Research Being a hypermarket that offers a wide range of food items and non-food items such as appliances and clothing, Carrefour is in a direct competition position with grocery retailer, supermarket such as NTUC FairPrice (Ng 2012) as well as appliances chains such as Best Denki (Krishnan, 2012), which might eventually affect their sales. On top of these competitors, Giant, a hypermarket open by Dairy Farm Group, is their major competitor. Reported by Krishnan (2012), Giant offers consumer lower price, compensating and outweighing travelling cost. Giant is also able to control consumers behaviour as products sold seems to be more appealing to broader segment of market. Hence, with these competitors at hand, Carrefour did not operate as well as expected. Looking at Carrefours 2011 sales report, illustrated in the pie chart below, the highest contributor of 43.2% is France. Aisa, has the lowest contribution of merely 9% which is approximately à ¢Ã¢â‚¬Å¡Ã‚ ¬73 Million (with the closure of Malaysia and Thailand stores). Source: http://www.carrefour.com/cdc/finance/key-figures/our-key-figures-/key-figures-folder/breakdown-sales.html In addition, reported by TODAY news (2012), in 2009, Aisa has accounted for 7.9% of Carrefours total sales of à ¢Ã¢â‚¬Å¡Ã‚ ¬85.9 billion, with Singapore contributing only à ¢Ã¢â‚¬Å¡Ã‚ ¬85 Million (TODAY/CNA 2012). Comparing it with 2011 annual report, sales revenue in Singapore have decreased. Therefore, the failed in Carrefour may be due to its strong competition in Singapore with its direct and indirect competititors. Objectives The main purpose of this research proposal is to investigate the perception of consuerms towards Carrefour against their competitors in Singapore. The objectives of the research proposal are as follows: To evaluate Carrefours performance in comparision to its competitors To examine factors influencing consumers behaviour in patronizing its preferred hypermarket/supermarket retailer To ascertain what kind (demographic, geographic, psychographic, behavioural) of consumer frequent Carrefour To investigate the degree of brand loyalty consumer have towards Carrefour Research Design Research Question With the aim of achieving the objectives set, research questions have to be formulated. The following are some example pertaining to the research proposal. Which of the supermarket respondent most frequent? In selecting a supermarket, what are the factors that respondent consider most? Rate the level of awareness respondent have towards Carrefour (1 being the most and 7 being the least) How frequent do respondent shop at any of Carrefours outlet? What are the prominent difference between Carrefour and other supermarket? Research Method Aliaga and Gunderson (2000) quoted from Muijs (2011, p.1) defines quantitative research as a method that explains the phenomena of collecting numerical data that are analysed using some mathematically based methods, in particular statistics. The researcher will thus be adopting a quantitative approach, employing primary research personal survey method, focusing on the phenomenon of consumers decision for patronizing a supermarket; their intentions, behaviour and attitude (A study on factors considered by consumers for patronizing a retail outlet 2010) and gather information on consumer awareness towards Carrefour compared to its competitiors. Personal Survey Malhotra and Birks (2007, p.265) and Malhotra (2010, p.211) defines survey as a method that gathers information based upon questioning respondents a variety of questions regarding their behaviour, intentions, attitudes, awareness, motivations and demographic and lifestyle characteristics. Most researcher noticed that survey is simple to administer and hence is a popular quantitative measure amongst all. Although it is argued that survey can be uncontrollable as respondents may be unable or unwilling to provide accurate responds (especially to motives or sensitive questions), it is recognised that due to the limited alternatives available, data collected will be consistent across and variability of results will be reduced (Malhotra 2010; Malhotra and Birks 2007; insights from decision point 2012). Rea and Parker (2012) further argues that commercial enterprises often use surveys to formulate market strategies for the potential widespread use, performance of new and existing products as well as finding out their market value. These aligns to the researchers aim and objective, to gather information on factors that affects consumer patronage behaviour as well as perception of consumer towards Carrefour. Furthermore, due to the surveys fixed-response alternative questions nature and consistent data gathered, coding, analysing and interpreting of survey results are relatively simplier for researchers compared to observation or experiment method. Appendix D shows a diverse survey techniques, and compares them against numerous factors, shown on appendix E. Personal interviwing street survey, occurs when respondents are intercepted while shopping or walking on the street (Malhotra and Birks 2007). Personal survey technique is a method to collect relevant data from target group and evaluation becomes easier (A study on factors considered by consumers for patronizing a retail outlet 2010), generalising the entire target population from a small amount of data gathered (Rea Parker 2012). Additionally, personal survey allows the researcher control the environment, to source for potential surveyee personally, collecting data from the right target segment (Gibran 2010; Rea Parker 2012). Moreover, response rate in persoanl survey can be significantly high as compared to other methods such as mail survey and speed of collecting data is also moderately high. Due to the characteristics of personal survey in appendix E, personal survey will be conducted by the researcher on consumers who patronize any supermarket or hypermarket in Singpaore to collect valuable data on their patronizing behaviour and their level of awareness towards Carrefour against their competitors. Formulate a plan Gibran (2010) suggested that, survey techniques includes selecting respondents randomly from the studied population in an unbiased mannar and having a standardized questionnaire for all respondents. However, Rea and Parker (2012) claims that physical characteristics of surveyee such as attire, cleanliness, manners etcetera is important when selecting respondent. On top of that, sample survey, where data will only be collected from a fraction of the studied population (Statistics Canada 2003, p.2; Rea Parker 2012), will be exploited by the researcher. It is noted that sample survey provides a economical and quicker way of obtaining sufficient information in the field. Hence, in this research, studied population refers to a representative number of consumers, particularly middle-aged women, who patronize any supermarket in any given time. As mentioned, there are two different issues. To attain the objectives, the questionnaire will be targetting at these two issues seperately where specific questions will be asked sequentially. First part of the questionnaire will focus on the factors affecting consumer partonage behaviour while the second part on consumers awareness towards Carrefour. Structured questionnaire, the degree of having a standardisation on data collection (Malhotra and Birks 2007), will be executed by the researcher in a formal and prearranged order,thus having a direct collection process. Although unstructured questions allows respondent to best express their attitudes and opinions towards the topic discussed (Malhotra 2010, p. 343), it will not be address as this is a quantitative research. Hence, the questionnaire will only contain structured questions. Most questions in the questionnaire will be in a likert scale (nominal scale) and respondents will be required to rate them accordingly base on their attitudes and behaviour. Rea and Parker (2012) recommends that sample size must be selected in an appropriate microcosm of the working population. They further concludes that larger samples yield higher degree of accurancy than smaller samples and hence researcher have to weigh the degree of accurancy with time and cost available. Analyze Data Before collating the results through computer-assisted programme, coding will be employed to facilitate capturing of data. This means that researcher will be allocating numerical values to every possible result of each question, giving it meaning (Malhotra 2010; Malhotra Birks 2007). Structured questions will be coded before the fieldwork is performed, while for unstructured questions, responses will be coded after the fieldwork (Statistics Canada 2003; Malhotra 2010, p.455). After which, coded values will be stored into the computer to analyse the questionnaires. As explained by Statistics Canada (2003, p.3), computer-assisted programme enables researcher to directly enter questionnaires into the computer and data will be captured and transform into readable format. Another benefit to computer-assisted programme is that inconsistent and invalid data will be identified instantly for researcher, providing a user-friendly and convenient form of identifying invalid data. The computer-assisted programme used will be SPSS, where data will be analysed into tabular or graphical form (Rea Parker 2012), making comparisons and interpret results for statistical analysis that will be reflected in the research proposal. As this research is about consumers behaviour towards patronizing, the research requires multivariate statistical technique where there are two or more measurements of each element and the variables are analysed simultaneously (Malhotra 2010, p.466). As mentioned, this research involves understanding the patronage behaviour. Hence, responses of the factors that affect respondents behaviour are dependent on each other. For example, respondent patronage behaviour will depend on the location, price, products offered etc. As such, referring to appendix F, a classification of multivariate techniques, the researcher is able to evaluate results with several methods such as cross-tabulation. Conclusion In summary, with the intention of discover the factors to consumer behaviour as well as establishing Carrefours market position in Singapore, the researcher have decided to employ personal survey method. Survey results will be analysed through coding followed by SPSS thereafter by the researcher to interpret these surveys into readable tables and graphs. Limitation Survey may seem to be the best suitable method for this research but it is time-consuming. As mentioned, this research is base on sample survey, which implies that it will not be 100% accurate as not everyone in the studied population is surveyed. Expected contribution With the mentioned objectives, and the methods used to meet these objectives, the researcher believes that this research will be able to contribute to Carrefour in analysing the reasons to their failure in Singapore, thus making improvements in other countries. This research can also set Carrefours management to react fast to changes in other international market, expending their market and prospects.

Health: Obesity and Overall Personal Feelings

The health/nutrition problem that I will be targeting will be my weight. The other problems will be affected by the weight which would be blood pressure, risk of getting diabetes, low energy, depression, etc. Four nutritional or physical exercise goals that I have are to lose at least 100 pounds, lower blood pressure, increase energy and confidence and lower risk of obtaining any other health problems such as diabetes. The actions that will be taken to meet each goal are to obtain a membership to an exercise facility, obtain a membership with a trainer, and work with trainer on an exercise plan and a nutritional plan as well. The anticipated setbacks or difficulties and approaches for overcoming them are the temptations to eating unhealthy foods in which I will remove myself from the situation so those temptations will not be available, loss of interest when it comes to actually going to working out either alone or with trainer in which I will change plan slightly to keep motivated enough to keep going. What I see as outcomes by which to measure success is the way that clothes are fitting will help determine the success of weight loss and weigh-in once a week to determine weight loss success. Evidence of the Plan’s effectiveness in addressing the identified problem or need will be the main piece of evidence in which will be my overall personal feelings and looks after goal is reached. Evaluation of potential health risks that may develop if the plan is not implemented is if I don’t follow through with this goal of losing the weight needed in order to improve my health then the risks involved could be higher blood pressure, end up diabetes, possible heart attack, depression worsens, etc. There are many different ways that my plan may be adjusted if there is a time when I am not physically capable of following through. I could step down the cardio workouts that I am currently on now. At this time I do between 30 to 45 minutes cardio Monday through Friday in the early morning before work. After working a full eight hours on my feet at work I then do an hour walk home. In the past when I was having abdominal pains I would remove the walk home from work.

Class President Speech Biology Assignment 5 Question 1 The pancreas is a large gland, situated in the peritoneal cavity, in the curve of the duodenum. It is the pancreas that is responsible for aiding the body’s endocrine system. (Darlington College 2011). The pancreas releases two endocrine hormones and it is these hormones that ensure the blood glucose levels within the body are constantly controlled. These hormones are glucagon and insulin and they are secreted from tiny clusters of cells within the pancreas, know as the islets of Langerhans. Glucagon is a hyper- glycaemic hormone, secreted by the islets alpha cells.Its main function is to increase the level of glucose in the blood. This is a vital process when blood sugar levels become low. Glucagon stimulates the liver to break down its excess glycogen into glucose. The glucose then passes into the blood stream and the homeostasis of blood glucose level is restored. Insulin is a hypo- glycaemic hormone that is secreted by the islets beta cells, in response to high blood glucose levels. Insulin decreases the level of glucose in the blood by stimulating its uptake by the skeletal muscles, liver and adipose cells.The skeletal muscles uptake glucose, to give energy for movement and the glucose that travels to the liver is converted into glycogen, and stored here until it is needed. The adipose cells use glucose for cell metabolism. Once sufficient glucose has been removed from the blood, the beta cells slow the secretion of insulin, so that homeostasis is again restored. (Glenn, 2005, pg84). Both insulin and glucagon are vital to ensure that the body constantly has enough fuel to supply its cells with the energy needed to enable them to function normally. Question 2 Peter’s normal blood glucose concentration will be approximately 4. mmol. After he eats his balanced meal his blood sugar levels will rise to around 8. 0mmol. This is because Peter’s meal will contain carbohydrates. In response to this rise in blood sugar levels insulin is secreted by Peter’s pancreas’s beta cells. The release of insulin facilitates the entry of glucose into his body cells and this vital process maintains the energy levels within the cell. When glucose is absorbed in the cells, the blood sugar levels fall again. This occurs because the excess sugar, present in the carbohydrates in Peter’s meal, that caused his blood sugar levels to rise, has been used up.This is what allows the blood glucose concentration to return to normal. (Glenn, 2005, pg85). When peters blood sugar levels drop, because he needs more food, glucagon is released from the pancreas alpha cells in response. Glucagon is a hormone that calls on the liver, which has its own glucose store, in the form of glycogen. Glycogen will release from the liver to allow the blood sugar to rise until it returns back to its normal rate. (Bowen, 2002). It is vital that Peter’s blood glucose levels are maintained at a normal rate, in-be tween his meals as large fluctuations in these levels can cause convulsions and could even induce a coma.Question 3 The body’s internal environment is constantly controlled and balanced by homeostasis. Homeostasis is the condition of equilibrium that is maintained through the body’s response to a change in conditions. There are many regulating systems within the body that work together to constantly control the internal environment. The nervous system and the endocrine system work very closely alongside one another to keep the body normal and in balance. Feedback systems are vital in keeping the body regulated. All feedback systems are made up of a receptor, a control centre and an effector.The receptor is able to detect any changes that may have occurred and send a message to the brain to tell it that it needs to respond. The brain acts as the control centre and is responsible for evaluating the messages it receives from the receptors. Once the messages have been proc essed the control centre generates a command, if one is needed. The commands are received by the effectors, which produce a response that is then able to change the controlled condition. (Darlington College 2011). A negative feedback system reverses the change in a controlled condition.When the body’s blood glucose levels fall too low, specialised receptors pick up this information and relay it the hypothalamus part of the brain, which forms the control centre. The hypothalamus then activates the response of the effector that allows the body’s blood glucose level to rise. When the levels become within normal range the receptors stop picking up the messages and no longer send them to the hypothalamus. This prevents the blood glucose levels then becoming too high and enables homeostasis of the internal environment to be restored. (Darlington College 2011). Question 4The body’s endocrine and nervous systems work very closely together to form the body’s major communication system. If a problem arises with one of these systems, homeostasis is upset. For instance: If the islets beta cells do not produce any insulin, such as in diabetes, the blood sugar levels will just continue to rise. This would cause extremely high blood sugar levels which would in turn go on to affect the body’s nervous system and could result in a coma occurring. The nervous system works in conjunction with the endocrine system by using nerve impulses and rapidly responding to stimuli, in order to adjust body processes.The integration of these systems is what enables homeostasis to constantly be maintained.
