Introduction to Computer Information Systems Essay Computer software is no longer a major barrier to widespread use of wireless information systems. Introduction To know about the connection of these topics it is must to know about the link between these phrases as well as the basic concept of these two. Firstly, to know what is computer software and wireless Information systems and then secondly to discuss their effects upon each other. Computer software is basically some programs or events that are written just to achieve certain functions by the software engineers. Events are the set of steps that are written and combined to make a program. Now there arises a question that what is a program then the answer of this question is that: Programs are basically a set of rules and instructions on the basis of which a computer act to achieve certain functions. To perform a specific set of actions on computers intelligently or normally is the basic need to write a program. Wireless Information systems are basically the systems that used wirelessly. What is â€Å"Wireless† and why and how question arises then? â€Å"Wireless†, as its name, shows that it means some sort of transport of data and information among wireless devices without using wires. It can be used in form of mobiles, PDA’s, and on large scale â€Å"Radio† is the example of it. Wireless information systems can be the range of mobiles, wireless devices, and networks. The device used for it is basically a device that is installed first and then it can be used. (Wireless network and information processing system, 2008) Certain Dependencies In case of Wireless information systems, there are certain dependencies. Among those dependencies some of them are very basic and are: the mobility of the user mobility of the resource Explanation These dependencies can be differentiated in a way that in case of user mobility it can be in the form of traveling user whereas the case with the second dependency is that a network if created among multiple PDA’s and now in this case, if the PDA’s are moving. Along with this dependency, there is certain other as well. Just to be a focus on the actual behavior of the wireless and then wireless information systems only two are mentioned here to emphasize the main and important factors affecting the wireless in general. Important features to consider about There are certain tendencies that are important to know about these systems. According to these, Information systems have to develop first. While developing these systems a software engineer needs to know the protocols (specific rules of dealing on networks) and standard to follow up on them and then to develop finally (Feldman, 2007). There are certain standards that need to follow while considering wireless. In this way, there appears a need to select a standard according to the type of wireless information system. Those standards are as follows: IEE802.11 IEE802.11a IEE802.11b IEE802.11g IEE802.16 IEE802.16a Open Air Home based Blue tooth based Discussion After implementation of these steps, architecture to develop a software program is required. When these wireless systems developed then these should cope with the problem fairly in real time. If an architecture of software program is designed in such a way that it is safe for security flexibility and other issues as well. If technology is implemented selected in an improved way then an information system can work well. If there are leaks in the design and programming tactics and technology implementation then there would be a lot of leak in the system as well that result in a very severe or drastic problem. In this way, it can say that software programs that developed to resolve a problem need attention in all these metrics to work upon and to get a better result. If there is a better program written by a programmer who is reliable and portable, efficient and of strong functionality then fulfill the better requirement in this case. Whereas if we are talking about the wireless informa tion systems things become more sensitive as we are dealing on real-time and gather a lot of security risks. That’s why after applying and implementing rules and regulations and following the standards will get the better results. The use of wireless information systems is beneficial for the companies and organization in various ways, first of all, it is accessible in minimum resources. It reduces the time and mobility issues problem and enhances the productivity of the organization in this regard.(Wireless Networking in the developing world session 2007) The use of wireless management systems can improve the effectiveness of applying multiple procedures. An output of these procedures when resulted in a good form then increased or enhanced the productivity of the organization in a fast manner. Well, reputed industries, companies, and organizations are referring towards these wireless information systems that are very fast growing. Along with all this, there are still new advancements are just coming on the way to increase the quality of the projects or to attain the benefits of the technologies as much as it can be.

Understanding Of Sociological Concepts And Theories Sociology Essay

Understanding Of Sociological Concepts And Theories Sociology Essay This essay will demonstrate the knowledge and understanding of sociological concepts and theories related to health, illness and health care. It will also look and explain the historical and contemporary patterns of inequality in health and illness. It will also critically discuss why some people are healthier than others. It will also Discuss insight of sociological methods of research discovery and evaluate the relevant data. Sociology of health is the study between different ethnic groups and individuals in human society. The twentieth century has witnessed a rise in life expectancy for people that live in industrialized countries compared to other parts of the world the standards of health and wellbeing are quite high. Research has shown that certain groups of people tend to enjoy a much healthier life style than others. Theses health inequalities appear to be in the larger socioeconomic patterns. Sociologists have attempted to explain the link between health and the variation in social class, gender, race, age and location (Giddens 2001). Research on class and health has shown a pattern between death and illness and an individuals social class. There have been two nationwide studies on health in the United Kingdom one of theses being The Black Report in 1980 (Giddens 2001). The Black Report, was commissioned by the government to look at data on health inequalities and to make recommendation for policy and research, which focused largely on materialist explanation of health inequality. The report emphasised the need for an all- inclusive anti-poverty policy and for improvement in education in order to reduce health inequalities (Macintyre 1997). Studies show that poverty can be bad for your health. Areas of the country with above average numbers of people dying young, that is before 65, are generally poor urban areas. Glasgow, London and many of the biggest cities in the North of England stand out in particular. Suicide rates amongst young men are four times higher amongst those with no known occupation compared to those in Social Class 1. People on low incomes are more likely to suffer episodes of serious depression. (BBC News 1999) In a speech on 27 March 1977 the then Secretary of State for Social Services stated: à ¢Ã¢â€š ¬Ã‚ ¦.. The crude differences in mortality rates between the various social classes are worrying. To take the extreme example, in 1971 the death rate for adult men in social class V (unskilled workers) was nearly twice that of adult men in social class I (professional workers) even when account has been taken of the different age structure of the 2 classes. When you look at death rates for specific diseases the gap is even wider. For examples for tuberculosis the death rate in social class V is 10 times that for social class I; for bronchitis it was 5 times as high and for lung cancer and stomach cancer 3 times as high. Social class differences in mortality begin at birth. In 1971 neo-natal death rates deaths within the first month of life were twice as high for the children of fathers in social class V as they were in social class I. Death rates for the post-neo-natal period from one month up to one year were nearly 5 times higher in social class V than in social class I à ¢Ã¢â€š ¬Ã‚ ¦ The first step towards remedial action is to put together what is already known about the problem à ¢Ã¢â€š ¬Ã‚ ¦ it is a major challenge for the next 10 or more years to try to narrow the gap in health standards between different social classes. Many cultures have different health and cultural beliefs such as in the Asian ethnic groups believe that the extended family have influence on individuals; the oldest male is the decision maker and spokesman. Stacy (1988) stated that various cultural social and economic factors all of which have their own roots in the eighteenth century Biomedical is one of the ways to understanding health and illness in the western cultures, but also being accepted not only by doctors but also by none professional. There is general agreement among contributors that there are a number of important characteristics Nettleton (1995.5) describes some examples these being Mid -body dualism which is accepting that the mind and the body can be treated with two different things, Mechanical metaphor looks at the theory of which that the body is a machine, Biomedical is described as reductionist in that there are tendency to reduce all explanations to the physical working of the body. All cultures have a known concept of physical health and illness, but most of what is recognized as medicine is a consequence of development in western society over the past three centuries. Premodern cultures, the family was the main institution coping with illness and disease. There have always been people who believe that you can be healed by different remedi es such as physical and magical in the non- western cultures throughout the world (Giddens 2001). The Bio-medical model there are three main theorys on why the bio-medical model of health is predicted. First disease is seen as a breakdown within the human body that diverts it from its normal state of being The germ theory of disease, second is the mind and body are able to be treated separately and the third being doctors who have been trained and are experts in treating illness and disease (Giddens 2001). Critics to this model say that the effectiveness of scientific medicine overrated. In spite of the prestige that modern medicine has acquired, improvement in overall health can be attributed far more too social and environmental changes than to medical skill. Effective sanitation, better nutrition and improved sewerage and hygiene were more influential particularly in reducing the rates of infant deaths and young people (Mc Keown 1979). Other critics like Ivan Illich (1976) states that modern medicine has done more harm than good.

Austins Ditch: The Political Necessity and Impossibility of :: Austin Politics Essays

Austin's Ditch: The Political Necessity and Impossibility of "Non-Serious" Speech ABSTRACT: This essay seeks to show that there are political implications in Jacques Derrida’s critique of J.L. Austin’s notion of performative speech. If, as Derrida claims and Austin denies, performative utterances are necessarily "contaminated" by that which Austin refuses to consider (the speech of the poet and the actor in which literal force is never intended), then what are the implications for the speech acts of the state? Austin considers the speech acts of the poet and the actor to be "parasites" or "ordinary language," "non-serious," and would relegate such speech to a region beyond his consideration, to a "ditch" outside the border of meaning for the performative. Derrida argues that the "contamination" Austin fears for language is necessary for its very performativity. If Derrida is correct, then the performative utterances of the state (e.g. the decree of the judge, "I sentence you...") from the biases of racial or sexual identity is also based upon an impo ssible desire, a desire that goes against the manner in which language functions. I argue that this desire for a just state cannot be satisfied unless racial and sexual identity is viewed not as "parasitic" and "poetic," but as necessary to the performativity of the state’s liberal power. "One will not be able to exclude, as Austin wishes, the 'non-serious', the oratio obliqua from 'ordinary language'." Jacques Derrida (1) In his lectures included in How to Do Things With Words J.L. Austin seeks to exclude from his analysis of performative speech all utterances that do not fall under his notion of "ordinary speech".(2) Ordinary speech that is performative, according to Austin, effects a circumstance by means of the speaking, e.g. a sailor names a ship or a judge says, "I sentence you to six months' probation." Often, the desired effect is not produced because of what Austin calls "extenuating circumstances". But Austin's main concern is for what he refers to as instances of "relative purity" in which there is less a chance of failure or "infelicity" (his term) to spoil the intentions of the speech. Also to be excluded from his considerations are instances of citations of performative speech, as in a play: ...a performative will be in a peculiar way hollow or void if said by an actor on the stage, or if introduced in a poem, or spoken in a soliloquy....Language in such circumstances is in special ways—intelligibly—used not seriously, but in ways parasitic upon its normal use—ways which fall under the doctrine of the etiolations of language.

Computer Addiction Essay -- essays research papers

Computer and internet have become daily features of our lives. Some people have displaced work, school, friends and even family with computer. When too much time is spent on the computer that it reaches a limit where family, social relationship, school and work life is interrupted, that people may be caught in addiction. Like any other addiction, computer addiction had replaced the importance of life with internet. Computers are bad for your health and decrease attachments with your true life. There are many signs and symptoms of computer addiction. A person might have a guilty feeling while on the computer, they might feel very sad and depressed when computer time is minimized or disturbed.

They also ignore their family or responsibilities to be online, lie to other people about the time spend on the computer, may get tempted in a relationship with a stranger which may end up into victimizatio...

Identify Marks and Spencers market position and determine why they nearly collapsed :: essays research papers

Identify Marks and Spencers market position and determine why they nearly collapsed Introduction Marks & Spencer is one of the UK's foremost retailers of clothing, foods, homeware and financial services, boasting a weekly customer base of 10 million in over 300 UK stores. Marks & Spencer operate in 30 countries worldwide, and has a group turnover in excess of  £8 billion. It has specific values, missions and visions. It’s main vision is ‘to be the standard against which all others are measured’, it’s main mission is ‘to make aspirational quality accessible to all’, and it’s main values are quality, service, innovation and trust. (www.marksandspencer.co.uk). By the end of 1998 though, there was evidence of a crisis occurring. Customers and media pulled together to assist senior management partake in an internal audit to identify the problems and see if they could come to a solution. The purpose of this assignment is to construct a SWOT analysis, highlighting each of the strengths, weaknesses, opportunities and threats that were highlighted in the internal audit. The SWOT analysis is contained within the marketing plan and is the third step in the marketing planning process, coming after the Marketing audit and before any assumptions. (Joisce, Ted (2002), Marketing Planning Lecture Notes – 14/10/02, Mission, Objectives, Strategy, Tactics) Conclusions will be drawn from the SWOT analysis, which will attempt to review the company’s position and identify the marketing priorities. Also, Marks & Spencer’s recent marketing activities will be critically analysed in order to ascertain what improvements have been made since 1998. This assignment will attempt to determine why Marks & Spencer nearly collapsed and what they have achieved in terms of success and failure as part of their recovery programme. Strategic wear-out occurs when an organisation no longer meets customer needs and the pursued strategy is surpassed by competitors. (Drummond and Ensor, Strategic Marketing Management, p. 149, Butterworth Heinemann) Marks & Spencer is a perfect example of a company that had a successful strategy but failed to adapt to the changing environment and have therefore suffered from ‘strategic wear-out.’ Evidence to support this quote comes in the form of Marks and Spencer sending very little on marketing communications and being overtaken by their competitors, but this will be explained later in the assignment. As Figure 2 shows, strategic wear-out refers to the lack of fit between an organizations strategy and the needs of the marketplace. This was clearly evident with Marks and Spencer when they became complacent about their customer service standards and thought their customers understood what Marks and Spencer stood for without marketing when all along they didn’t.

Serial Killers as Heroes in Popular Culture

â€Å"When asked to justify the extremely sadistic nature of his murders, Doe replies: â€Å"If you want to people to pay attention, Detective, you can’t just tap them on the shoulder anymore. You have to hit them with a sledgehammer. Then you’ll find you have their strict attention. † This is a prime example as to why the media can get, and keep the attention of their audience when it comes to being a serial killer. The media feels that the more people see of a particular crime, the less they are inclined to go out and commit heinous crimes. On the other hand, it could be that they just need the ratings to keep their show going and they really do not care what their audience is looking at or how it makes them feel. The media in my opinion only care about their ratings and how many viewers they have. The media should focus more of the energy on the victims and what was taken, rather than focusing on the killer or killers. During this week we watch Natural born Killers, and I thought that this movie showed every aspect as to why the focus should not be on the killers. Who in their right mind would decide to do a live taping of an interview with a serial killer, and then decide to let the prisoners view the taping. This shows that the producers only cared about the ratings. They did not have to agree with the request, but they did not want to lose their number 1 reporter either. They put their ratings and sponsors above their audience and a lot of people lost their lives, all because someone higher up thought it was ok to do a live show with a serial killer. In my mind I am thinking, this man is not the president or anything so why should he get all the attention. Why someone of this nature should even be allowed to see the light of day. Why, because we as society crave that energy that is sent from the screen to our living rooms. We want to feel sorry for the killers because it’s in our nature to think that maybe this person could have been saved, or that they were truly wronged somewhere in their life. I truly do think that the prisoners viewing the show as it aired played a big part in the major riot that occurred. I am not saying that it could not have happened at any other time, but in this case with everything that was going on, this was the wrong time to allow prisoners access to this particular show. The media puts too much information out there for anybody to see, and society is the one who ends up suffering the consequences.
