Book Theme (Key Quote): â€Å"Ethics and fair treatment play important roles in managing employees at work. Of course, few societies rely solely on managers’ ethics or sense of fairness to ensure that they do what’s right by their employee.† 4. Abstract: I. Ethics and Fair Treatment at Work. Ethics are normative judgments based on questions of morality. Ethics refers to what you stand for whereas fairness and justice are seen in terms of a decision’s result and the process of arriving at the same. Many countries have laws and legislations governing worker’s rights, not leaving them solely to an employer’s ethics. II. What Determines Ethical Behavior at Work? Several influences may determine whether a person acts ethical or not at work. They include: the boss: the  company; the organizational culture aided by a code of ethics; and the person themselves. III. How Managers Use Personnel Methods To Promote Ethics and Fair Treatment? Personnel methods such as selection, ethics training, performance appraisals, reward and disciplinary systems, managing compliance and personnel related method for ensuring fair treatment are tools which managers use to promote ethics and fair treatment in the organization. IV. Managing Employee Discipline and Privacy. Employee discipline may be punitive or non-punitive but should be fair and progressive, with an appeal forum. Employee screening and background checks are useful appraisal tool but should respect privacy laws or be given employee consented. V. Managing Dismissals. Fairness should be communicated in the involuntary termination of an employee’s employment and should be upheld by contractual agreements that show support for the same between the firm and the employee to avoid wrongful discharge claims. Layoffs, downsizing or closing plants should be down strategically and cautiously within legislative frameworks. 5. Brief Discussion of Book/Article Units/Sections/Chapters: I.

Organizational morale ab. Productivity ac. Commitment VI. Practitioner/Researcher Value of Book: A. The practitioner value of the book – The chapter â€Å"Ethics, Justice and Fair Treatment in HR Management† is of great practitioner value for several reasons. These reasons include firstly, the chapter’s readableness (the state or quality of being readable). The chapter has a uniform layoff where its main points or learning outcomes are indicated in an emboldened blue font of serif. Subtopics within these learning outcomes are given emboldened  red fonts of sans serif and further subtopics are indicated using emboldened green fonts of sans serif. Thus the chapter is uniformly organized and makes for easy reading and finding of key concepts and other information. Definitions are clearly highlighted at the foot of each page that has a gray background. The chapters’ practitioner’s value is shown also by the several tables and charts that conveniently summarize large amounts of information making for quick referencing by any practitioner. An example of this includes figure 14-12 on page 553, which shows the â€Å"Median Week of Severance Pay by Job Level†. This summative and quick reference format of key textbook and practical procedures for the issuance of severance is essentially useful to practitioners looking for reliable and timely solutions to everyday challenges. The chapter’s practitioner value is further attested to by several case studies and practical examples that show the key concepts presented being use in the real world and having practical application and relevance. Several case studies including that involving the infamous Enron (page 562) presents to the practitioner the relevance and implication of ethics by an organization. Comprehensive case studies are also presented at the end of the book in Appendix B such as that which deals with the ethical underpinnings of conduct of BP Texas management in relations to the March 2005 explosion. Practicality of the book/chapter is attested to by examples like that on page 547-48 which presents an example of employee monitoring software, thus presenting to practitioner a practical example of the concept of employee monitoring and furthermore giving a suggested tool to implement the same. Finally the chapter’s practitioner value is depicted by several step-by-step procedures that give the practitioner easy and ready to use procedures that they can easily implement for results and solutions. Page 546 gives an example of this for disciplining employees without punishment offering a readily available reference tool and guide for the practitioner to administer the same. B. The researcher value of the book The chapter (book) contains prodigious referencing. From its charts to tables to defining of key terms are given full reference linking information to their authors, websites and primary sources. Each chapter has its own endnote reference listing which gives all sources referenced as per the chapter. The sources are mainly in the form of scholarly journals and  articles attesting to the credibility of the information presented in the chapter. This chapter in question has about a WHOPPING 117 sources as per the information presented therein. Sources are easily verifiable. The books content are easily accessible as it contains an extension name and organization index with some 1200 entries. Its subject index is quite impressive as well in terms of its precision of search terms, concepts and points. The book/chapter presents an impressive Evidence Based HR section that presents evidence of how managers manage based on facts and evidence lending credence to the usefulness, credibility, applicability of the information presented. The book also presents authoritative findings and guidelines from professional bodies including The Society of Human Resource Management or SHRM as well as brief In-Text Study Guide from the SHRM organization. I therefore fully believe that the book is fully valuable to the researcher. VII. Final Impact Statement: In terms of ethics, justice and fair treatment in human resource management, we glean the importance of firstly the individual having a firm ethical framework, the organization also fostering the same and the society which embellishes the same. Governments are the regulating and enforcing entities of the same. We note in closing the authors remarks: â€Å"Of course, few societies rely solely on managers’ ethics or sense of fairness to ensure that they do what’s right by [to] their employees.† (Dessler, 2011, p. 533.). Instead we see legislations are used which at the minimum, organizations tend to subscribe to, and which satisfies both parties.

Atomic Energy: Good and Bad Essay

The use of nuclear energy is controversial because it can be used to wreak havoc upon mankind. Fission, or the splitting of atoms, can be used to release extreme heat and radiation. During World War II, the United States decided that this would be a powerful weapon, so they dropped two fission bombs over Hiroshima and Nagasaki, Japan to end the war. Many buildings were desotryed and thousands of innocent civilians were killed. After that, the world viewed nuclear bombs as dangerous new weapons that could devestate entire cities. Also, the radiation released from nuclear fission is harmful to living organisms. In 1986, a steam buildup in a nuclear reactor in Chornobyl, Ukraine caused an explosion that released tons of radiation into contact with people and animals. Thirty-one deaths resulted from the accident. Traces of the radiation were found in areas far away from the reactor because they traveled by wind. After the accident, the radiation still affects people in the contaminated areas; thyroid cancer in people has been increased due to the radiation. I think the benefits of nuclear power definitely outweigh the potentional dangers. Nuclear power is a very efficient source of energy. For example, it can be used to provide electricity for cities. Nuclear reactors would split radioactive elements to form heat, which would produce steam to turn turbines. Then electricity would be created to power major towns and cities. We do not need to worry about nuclear meltdowns because of the safety measures in nuclear reactors. The Chernobyl accident would be a thing of the past. Nuclear energy is also abundant, unlike fossil fuels (coal and oil). We don’t have to worry about running out of radioactive elements. However, fossil fuels are the complete opposite; gasoline prices have skyrocketed over the past thirty years, and scientists predict that gas would become a rarity in the year 2075 or so. I do not think all countries should agree to limit atomic weapons. Even if a country has only 200 atomic weapons, they can still easily threaten other  nations. Leaders should be able to buy what they desire with their nation’s money without having to worry about breaking any agreements. Perhaps a better solution is to ban atomic weapons altogether; that way, the world don’t have to worry about nuclear war anymore. If a country is suspected of possessing nuclear weapons, then that country would probably be wiped off the map (courtesy of the United Nations, they are the sheriff of the world.) Or maybe we should allow all countries to stockpile only ONE nuclear warhead for every country on earth. So if there are 200 countries in the world, your country could only stockpile 200 nuclear warheads. That way, if you bombed every country on earth, you would only have one warhead left to defend yourself with. I think it would be a pretty wicked awesome system. Atomic energy was used to cause death and destruction, but now it is being used to help light up the world. When the responsible are in charge of nuclear power, then everyone benefits! Atomic power is a great example of wonderful technology.

Analysis of Saudi Arabia Press Essay Example | Topics and Well Written Essays - 2250 words

Analysis of Saudi Arabia Press - Essay Example The essay "Analysis of Saudi Arabia Press" talks about the main functions of print media in Saudi Arabia and how the government controls it after the events occurring in Bahrain. The Saudi press remained controlled, applying no pressure on to the state authorities in relation to their handling of the Bahraini events and abstaining from the criticism of other governments. The Saudi government desired to be viewed as central to the social structure whereas the Saudi print media was to serve as a gatekeeper of what the Saudi people should think about. Then, it may be hypothesized that the function of the system of print media in Saudi Arabia was in accordance with the authoritarian press model, by which the press is considered as "a servant of the state and it is responsible for a larger part of its content to the power figures who are in charge of the government at any particular time". Indeed, if this model is applicable to the Saudi print media then the hypotheses given below would b e likely to hold true: H1 a: The developments in the field of politics and military/defense in Bahrain would be extremely newsworthy. H1 b: The type of news, for the political and military developments in the Bahraini conflict, would be largely domestic. H1 c: The tone of the news, for the political and military developments in the Bahraini conflict, would usually be positive. H2: The individual newspapers would offer similar levels of coverage to the different themes that have been presented by the news items.

Develop and implement a diversity policy at work place Essay

Develop and implement a diversity policy at work place - Essay Example The sales force and customer care representatives belonging to different cultures (Barak, 207) give the customer the feeling of oneness which generates favourable possibility in ensuring high sales. The benefits at group and departmental level are huge. The organisation has bigger platform to play with the help of complementary skills and dynamic capabilities. Many minds, each one with different thoughts and view can significantly increase the number of alternatives out of which few are to be chosen. The different thoughts can bring out many aspects of the problems leading to better solution. The creativity is multiplied (Pride, Hughes & Kapoor, 188) and the monotony is shattered. At individual level, the employees learn about various cultures and acquire new skills with the help of each other (Daft & Lane, 442). Diversity can be harmful to the organisations if and only if it is not recognised, accepted and well treated (Dubrin, 59). It is highly possible that difference of opinion causes conflicts which can hamper the productivity and performance. It is, therefore, crucial that organisations cater towards diversity and take effective measures to reap benefits out of it.

Human Resource Management Employee Selection Processes Research Paper

Human Resource Management Employee Selection Processes - Research Paper Example Methods of selection on the other hand should have some reasonable quality as dictated by the concept of utility. Selected employees should add value to the organization. A method that selects employees who cannot add value to the organization is an ineffective method. Lastly, selection process must adhere to the legal regulations and provisions of employment such as discrimination and equal employment regulations (Ullah, 2010). Organizations selecting employees should ensure that there are no discriminations and equal employment opportunities. Equally suited candidates must be subjected to equal interviews or selection process. One of the easiest and most effective approaches in selecting one of the two equally suited candidates is the thorough analysis and evaluation of experiences and job specifications. There is no doubt that there must be one candidate who is slightly more experienced that the other or has an additional qualification. In the event that they have the same years of experience, academic qualifications, and admirable track or records, the two equally suited candidates should be subjected to various selection processes such as aptitude of panel interview to critically evaluate their uniqueness (Knouse,

Operational plan Case Study Example | Topics and Well Written Essays - 2500 words

Operational plan - Case Study Example The company would use various promotional tactics to inform the consumers that the company complies with EU regulations regarding meat products so that consumer trust in the company would be revived. It is important to improve the consumer confidence towards meat products that has had certain negative publicity in recent times. When the demand for fresh meat would increase in the market, it would definitely impact Larsini’s position within the market. Along with this, the company also needs to develop a pricing strategy. 29 Larsini is family business which sells salami and beef with traditional taste, special ingredients and good quality. Salami is traditional food in Italy where everyone enjoys eating it. A man called Giuseppe Ghiberti (the president) started to make salami in 1908; more than century ago. Since then, the Larsini Company was their starting point. In the past, Italy was not a rich country but Larsini made their effort to provide traditional taste with the best quality to the Italian people. The starting was a small butcher’s shop in the old part of Firenze. Then they decided to expand further in Italy. However recently, the company has been at the point of bankruptcy. Even though Larsini still enjoys a good market image, the company has been facing losses. To account for these losses and in order to turn around the company toward profits, seven business students have been hired to analyze the situation and propose recommendations for the improvement within the company. This part of the report would be dealing with the marketing analysis and proposal to improve the brand image and perception of the company among the customers. Larsini’s mission is still the same as it was when it was established in 1994 by the President’s father and his mission was to satisfy the customer by providing them full service they need and to fully know customer needs and accomplish them in addition to find quick solution in order to offer tasty product at the

Understanding and assisting Megan Griffiths Case Study

Understanding and assisting Megan Griffiths - Case Study Example Megan Griffiths is a 27 year old single parent who has 4 children. She has had four different boyfriends since she was aged 13 and has been living on her own since she was 16 years old. Megan’s first daughter, Jane was in foster care from birth until the time her mom reached the age of 16. Understanding the situation Megan is in may be easier with some knowledge of the developmental stages that occur during adolescence. It seems that, because her first pregnancies occurred during her teen-age years, one must first have a solid understanding of the state she was in at that time. Along with looking at the actual information provided by Megan herself, the literature can provide a good framework for case planning. Pierno (1995, p-1) has provided some excellent information in her work on adolescent pregnancy. She points out that Freud’s concept of adolescence as a time â€Å"fraught with struggle†¦a time when the ego is torn between the strong impulses of the id and the restrictions of the super ego. This conflict makes adolescence a time of tremendous stress and turmoil. She goes on to contrast Freud’s theories of psychosexual development to Erik Erikson’s Psychosocial Theory which takes a broader view of the factors impacting human development. Erikson proposes that all people face a series of developmental tasks but he does not see individuals getting ‘stuck’ in a phase, as Freud believed. Erikson’s theory is that people will rework old issues in the context of certain tasks and then move on. In Megan's situation, having had a total of four children she seems to have initiated the process of 'moving on' by accessing help for a depression that was diagnosed when she was fifteen years old. There appears to have been significant progress in this area in that she accessed training as a nursery nurse and is working part time in a children's play group and nursery. However further research and reflection have led this writer to conclude that Piaget's theory is the most appropriate model for understanding Megan's situation. Piaget's theories about cognitive development (3) through adolescence involve ".movement from concrete to abstract thinking and a decrease in egocentric thought." Pierno (1995, pp. 2-3) points out that "The acquisition of formal reasoning skills allows older adolescents (about age 15) to think about many possible outcomes that do not exist now.An adolescent with formal reasoning skills (with appropriate guidance) could try to think through the full implications of parenting a newborn." Risk taking, part of the normal behavioral development as seen to occur during adolescence may have been the basis for Megan becoming sexually active in her early teens. This is a time when young people typically work at finding ways to "shape their identities, try out new decision making skills, develop realistic assessments of themselves and gain peer acceptance and respect (Ponton, l997; Jesser (1991)" (1995 p-3) Pierno points out that "unfortunately, some of the risks that adolescents pursue may pose a real threat to their health and well being. These include motor vehicle accidents, pregnancy, alcohol and drug abuse and cigarette smoking." CURRENT CASE PLANNING Understanding Megan's early behavior would be helpful in working with her current

Race and the Death Penalty Research Paper Example | Topics and Well Written Essays - 3750 words

Race and the Death Penalty - Research Paper Example In every modern society, there are authorities to impose punishments on wrongdoers and the nature of authorities varies with the kind of offenses. For example, a child who breaks the rules of a family at home is punished by his parents or the other elderly members. But, in the society when someone gets involved in illegal activities is punished by the criminal judicial system. There are two major reasons for inflicting punishment on criminals: one belief is that it is fair that people who break the law be punished according to the level of his offence, and the second belief is that punishments will discourage offenders from repeating their wrongdoings in the future and will also put fear in the minds of others from doing wrong. These two beliefs are universal in every human society. The debate surrounding the necessity of punishments including capital punishment, therefore, does not focus on the â€Å"basic principles but on the fairness, appropriateness, and effectiveness of specif ic punishments for specific offenses.†1 Because of the irrevocable nature of the death penalty, it is the most criticized form of punishment. In the United States, racial prejudices were pervasive and played an important role in the decision of the jury in regard to death penalties as â€Å"the color of a defendant and victim’s skin plays a crucial and unacceptable role in deciding who receives the death penalty in America.†2 It has been seen that an offender is more likely to get the death penalty if the murdered victim is a white man. This paper focuses on the racial prejudices surrounding death penalty in the United States. Before studying the death penalty from the angle of racial prejudices it is important to note that racism is a major part of the American society.

Current Therapy Trends for Specific Phobias and Their Long-term Essay

Current Therapy Trends for Specific Phobias and Their Long-term Effectiveness - Essay Example A simple phobia, which was earlier known as simple phobia is thus a lingering and unreasonable fear that is caused by the presence or thought of a specific object or situation that normally poses little or no real danger. Faced by such an object or situation the response is an immediate reaction that causes the individual to feel severe anxiety that. The consequence is that the individual avoids the specific object or situation. The severe distress caused to the individual interferes with the ability of the individual to function normally. Though adults with specific phobia recognize and understand that the fear they feel is excessive or not given to reason, they find themselves unable to overcome such fears (Specific Phobias). â€Å"Persistent fear of a circumscribed stimulus (object or situation), other than fear of having a panic attack (as in panic disorder) or of humiliation, or embarrassment in certain social situations (as in social phobia). The fear or associated avoidance behavior significantly interferes with the person’s normal routine or with usual social activities or relationships with others, or there is marked distress about having the fear. Specific phobias are of different types and are classified based on the object or situation that causes it. Specific phobias include animal phobias like fear of dogs, snakes, insects, or mice; situational phobias like flying, riding a car, driving, going over bridges or tunnels, or of being in an enclosed space; natural environment phobias like fear of storms, heights, or water; blood-injection-injury phobias like, fear of seeing blood or of invasive medical procedures, such as blood tests or injections, or fear of being injured; other phobias like fear of falling down, fear of loud sounds, or fear of costumed characters, such as clowns. An individual could be affected by one or more specific phobias (Specific Phobias). The U.S.

Tibmer Jack Essay Example for Free

Tibmer Jack Essay Timberjack was the world’s leading manufacturer of heavy equipment for the professional logger, with an overall market share of 25%. In 1995, Timberjack had 1,600 employees, generated sales of 627 MM USD and a net profit of 88 MM USD. Industry Background In the past the forests were cut manually using the chain saws, and the cut logs were taken out of the forest using horses. The logs were cut as per the requirements manually. But in the twentieth century this started transitioning, and in 1960-1990s there was surge in the use of machinery in forest cutting, loading etc. Timberjack, Blount, Caterpillar, John Deere, and Valmet were the companies providing machinery for cutting forests. Timberjack was the company catering to the 25% of the market share. Product Offering As the old manual chain saw methods for cutting trees were disappearing, feller bunchers, skidders, delimbers and log loaders were used instead. Timberjack provided a variety of heavy equipment that served the new method of cutting trees. The price of these equipment was well attached to pulp and lumber prices which in turn are highly dependent on the on the overall strength of the economy Timberjack follows a series of steps to select and decide its future manufacturing software package. The process is straightforward, which goes through DFP, vendor list, narrow down vendor list, site visit and implementation consulting for the final two vendors. Basically, Timberjack is taking one step after another throughout the processes. While it might not be a perfectly precise analogy of system development life cycle, it does share characteristics with the traditional waterfall model of SDLC (system development life cycle). A typical process of traditional SDLC is usually comprised of the following steps: 1. Project planning, feasibility study 2. Systems analysis, requirements definition 3. Systems design 4. Implementation 5. Integration and testing 6. Acceptance, installation, deployment 7. Maintenance In Timberjacks case, the life cycle starts with the decision from headquarter that a unified software package will be implemented for the whole organization, even for distributed locations. During this phase, the organization identified its current short coming of the existing solution and the necessity to move to a new system, as well as cost-benefit implications and a rough schedule. A decision of ;to build or to buy; has also been reached, which is to buy. During the second phase of the SDLC, there are various types of implementation model. According to Timberjack, it seems that it is following a waterfall model which characterizes with a prolonged need analysis phase. Once a whole list of function requirement is made, it is hardly changed later on. As a matter of fact, Timberjack devoted major time and investment into this phase. The RFP spanned nearly as long as four months and cost 75,000 USD. Although the RFP was treated as valuable outcome, the effort was less appreciated by the Sweden operations because they were in need of a quick replacement of their current software system. The following steps of SDLC, including system design, implementation and etc will depend on which vendor Timberjack eventually selected. Therefore, again, Timberjack took the time evaluated and investigated extensively. Timberjack considered several key metrics that were: cost, time of development and deployment, flexibility of customization and etc. Using the criteria, Timberjack was able to narrow down the vendor list to two bidders. With further review and consideration, Timberjack would finally be able to locked down one vendor that suited best to their situation.

Lets discuss bus topologies first, bus network topologies is a single cable which use to connect to different points between network, as it only have one channel to support the bus network for communication, so the total capacity will send to all the points averagely. When a point want to send instructions to another point, it will announce a message to all the points thru wire and all the points will see it but only the destination point will receive and return the message to the sender point, other points will not give any response. Bus network topologies are cheaper than other network topologies because it use less cable and materie and also the installation is easier than other topologies. But because it is a single cable, when there have many points connect to the device, it will slow down the transmission speed and the total capacity. On the other hand, once the network have problem, it cost many times to fix it as you have to check all the cable connection to find out the problems. Also in a bus topology, once a single connection failure, it will stop the passage between all points. (The image of the About.com guide) Second topologies which we are going to discuss is Ring topology. In a ring network, each apparatus connected to two users for communication purpose. It looks like a circle and the message move around the circle to each point use single direction. Each node connect to its own cable to the Medium Attachment Unit (MAU). Ring network topology is easy to install and reconfigure and also easy to add new node as only two connections need changes. However, Ring network is not too convenience for the user as the data have to pass through all the points before getting to the destination. For example, if one network have six user, when the A computer want to send message to F computer, it have to pass through B, C, D, E computer and then to F. And if one network failure, whole network will disable because it only have single pathway to transmit the data. (The image of the About.com guide ) The third network topology is Star. Star network is one of the most usual computer network topologies. It features a central connection point call hub or concentrator (Bruce A Hallberg 2005) and it will radiate to other points. The characteristic of Star network is the hub or concentrator work as a central union to provide different route for signal send out to any two sites. Data on star network will send the message to hub or concentrator first before send to the destination point. Hub or concentrator works like a repeater for the data flow. In the star network topology, if one connection stoppage, only one node will lose the connection from this site and it wont be affect to other networks. On the other hand, it will be easy to find out the problem as all network is obey to hub, so once the network out of service, mostly it must be some problem with the hub and the problem can be fix quickly instead of checking all the points. Furthermore, as hub is control everything included add or remove devices, that means Star network is easy to install. If you want to add some new devices to the network, just need to connect the cable to hub and other computer will detect the devices and can use it. It save lots times to install the devices to all computers separately in the network. Moreover, hub can also be act as a backup file, once the network is not work, you can move to another computer and using the data from hub. Although star network is more stable than other network topology, but star network is more expensive as it needs more wires to support the network. And because it is fully obey to hub, once there have many nodes, the network maybe slow down. (The image of the Florida Center for Instructional Technology College of Education, University of South Florid 1997.) Last network topology we have to share is Mesh. Mesh network is a network where all the nodes connected to each other with different ways, maybe single hop or multiple hops. In a mesh network, if one node or cable have problem occur, there will have another way to communicate with other node, it wont be halt the whole network. Mesh network will also default the short way automatically while the message moving on the mesh network, that means the data no need to pass through all the points before reach to destination, it save many times for transaction the data. Mesh network is a network which is not easy to interruption by connection problem as there have many possible patterns that can use. When one node failure to connect, mesh network will find another way to reach the destination easily. Mesh network separate to two similar types: Full mesh and Partial mesh. Full mesh which every node will connect to each other so the network can provide best redundancy function. Once one of the nodes breakdowns, connection between the networks will be stronger under full mesh network because there have more possible route to reach to destination. Because of more wires need, so full mesh network is expensive than partial mesh network and it may also affect the set up procedure because of the complexity. For the economical reasons, some of the company will prefer to use the partial mesh network. In partial mesh network, devices are only connects to a subsection node instead of all nodes. This may affect the entire network once the connection have problem because it only have one or two ways to reach the destination point. Although the communication between the networks is not as strong as full mesh network, but the cost is cheaper than it, so nowadays partial mesh network is more popular than full mesh network. (The image of the network dictionary 2004) Physical communication media is a path that can let the electronic data move from one computer to another. And now will going to describe different physical communication media, for example Twisted-Pair cable, Coaxial Cable and Fiber-optic cable. The first cable we are going to talk about is Twisted-Pair cable. Twisted-pair cable which can be subdivided as unshielded twisted pair (UTP) and shielded twisted pair (STP) (Bruce A Hallberg 2005). Both UTP and STP have eight separate brown metal wires and cover by insulate material. Besides, each pair of wires was wound to each other. UTP and STP not only have similar structure and also have similar transmission technology. Even though STP has a better protection interface and quality than UTP, but it cost more expensive and not easy to install. Using Twisted-pair cables advantage is its size is smaller than others so that it will easy to install and it cost cheaper than Coaxial cable and Fiber-optic cable. On the other hand, the transmission signal is shorter than other communication media and the coverage area is only 100 meters. Another cable we are going to talk about is Coaxial Cable. Coaxial cable is cover by 4 layers: copper wire, insulation, copper mesh and cable jacket. Coaxial cable can aid 10-100 Mbps and it coverage 500 meters. (Scribd n.d.) The advantage of Coaxial Cable is it can run for a long distance between network but use less power. The cost of Coaxial cable is cheaper than Fiber-optic cable and because of it use for many years, so it will be more popular. However, the size of Coaxial Cable not as thin as Twisted-pair cable, so it will be difficult to install and relatively the set up fee will be higher than Twisted-pair cable. The last one we have to talk about is Fiber-Optic cable. Fiber-Optic cable is made by narrow core and insulates material. It use the lights to transmission the date. Most of the corporate network will use Fiber-optic cable as back bones to connect different network. The advantage of Fiber-optic cable is it has a higher data speed and the higher bandwidth is good for future development. But Fiber-optic cable is not quite flexible as it cannot curve, so it will be more difficult to install and the cost is the most expensive one. Different computers have its own different purpose, we are going to compare Microcomputers, Laptop computers, Minicomputers, Mainframe computers and Supercomputers size, speed, processing capabilities, price and how many users can use at the same time. Types of computers Microcomputers Laptop computers Minicomputers Mainframe computers Supercomputer Size Fits on desk Small and conveyable Size in between microcomputers and mainframe computers Partial room of apparatus Full room of apparatus Speed Up to 400 million Up to 400 million Thousands to millions Millions Millions to billions Processing capabilities Word process Surfing the web Database management Calculations Email function Word process Surfing the web Database management Calculations Email function Web surfing Check email Basic productivity software (Daniel J.Gansle,2010) Processing data quickly and information storage, mostly using on airline system, back or insurance company. Process very large amounts of date, such as weather forecasting and government. Price of computers From $2500 up to $17000 From $2500-up to $23000 From $5000-$15000 $300,000- several million dollars Several million dollars and up Simultaneously connected users For individual use only For individual use only Two to four thousand Hundred to thousand Hundred to thousand

Application of complex number in engineering

Application of complex number in engineering INTRODUCTION A complex number is a number comprising area land imaginary part. It can be written in the form a+ib, where a and b are real numbers, and i is the standard imaginary unit with the property i2=-1. The complex numbers contain the ordinary real numbers, but extend them by adding in extra numbers and correspondingly expanding the understanding of addition and multiplication. HISTORY OF COMPLEX NUMBERS: Complex numbers were first conceived and defined by the Italian mathematician Gerolamo Cardano, who called them fictitious, during his attempts to find solutions to cubic equations. This ultimately led to the fundamental theorem of algebra, which shows that with complex numbers, a solution exists to every polynomial equation of degree one or higher. Complex numbers thus form an algebraically closed field, where any polynomial equation has a root. The rules for addition, subtraction and multiplication of complex numbers were developed by the Italian mathematician Rafael Bombelli. A more abstract formalism for the complex numbers was further developed by the Irish mathematician William Rowan Hamilton. COMPLEX NUMBER INTERPRETATION: A number in the form of x+iy where x and y are real numbers and i = -1 is called a complex number. Let z = x+iy X is called real part of z and is denoted by R (z) Y is called imaginary part of z and is denoted by I (z) CONJUGATE OF A COMPLEX NUMBER: A pair of complex numbers x+iy and x-iy are said to be conjugate of each other. PROPERTIES OF COMPLEX NUMBERS ARE: If x1+ iy1 = x2 + iy2 then x1- iy1 = x2 iy2 Two complex numbers x1+ iy1 and x2 + iy2 are said to be equal   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  If R (x1 + iy1) = R (x2 + iy2)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  I (x1 + iy1) = I (x2 + iy2) Sum of the two complex numbers is   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  (x1 + iy1) + (x2 + iy2) = (x1+ x2) + i(y1+ y2) Difference of two complex numbers is   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  (x1 + iy1) (x2 + iy2) = (x1-x2) + i(y1 y2) Product of two complex numbers is   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  (x1+ iy1) ( x2 + iy2) = x1x2 y1y2 + i(y1x2 + y2 x1) Division of two complex numbers is   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  (x1 + iy1) (x2 + iy2) = x1x2 + y1 y2)x22+y22 + iy1x2  ­ y2 x1x22+y22 Every complex number can be expressed in terms of r (cosÃŽ ¸ + i sinÃŽ ¸)   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  R (x+ iy) = r cosÃŽ ¸   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  I (x+ iy) = r sinÃŽ ¸   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  r = x2+y2 and ÃŽ ¸ = tan-1yx REPRESENTATION OF COMPLEX NUMBERS IN PLANE The set of complex numbers is two-dimensional, and a coordinate plane is required to illustrate them graphically. This is in contrast to the real numbers, which are one-dimensional, and can be illustrated by a simple number line. The rectangular complex number plane is constructed by arranging the real numbers along the horizontal axis, and the imaginary numbers along the vertical axis. Each point in this plane can be assigned to a unique complex number, and each complex number can be assigned to a unique point in the plane. Modulus and Argument of a complex number: The number r = x2+y2 is called modulus of x+ iy and is written by mod (x+ iy) or x+iy ÃŽ ¸ = tan-1yx is called amplitude or argument of x + iy and is written by amp (x + iy) or arg (x + iy) Application of imaginary numbers: For most human tasks, real numbers (or even rational numbers) offer an adequate description of data. Fractions such as 2/3 and 1/8 are meaningless to a person counting stones, but essential to a person comparing the sizes of different collections of stones. Negative numbers such as -3 and -5 are meaningless when measuring the mass of an object, but essential when keeping track of monetary debits and credits. Similarly, imaginary numbers have essential concrete applications in a variety of sciences and related areas such as signal processing, control theory, electromagnetism, quantum mechanics, cartography, vibration analysis, and many others. APPLICATION OF COMPLEX NO IN ENGINEERING: Control Theory Incontrol theory, systems are often transformed from thetime domainto thefrequency domainusing theLaplace transform. The systemspolesandzerosare then analyzed in the complex plane. Theroot locus,Nyquist plot, andNichols plottechniques all make use of the complex plane. In the root locus method, it is especially important whether thepolesandzerosare in the left or right half planes, i.e. have real part greater than or less than zero. If a system has poles that are in the right half plane, it will beunstable, all in the left half plane, it will bestable, on the imaginary axis, it will havemarginal stability. If a system has zeros in the right half plane, it is anonminimum phasesystem. Signal analysis Complex numbers are used insignal analysis and other fields for a convenient description for periodically varying signals. For given real functions representing actual physical quantities, often in terms of sines and cosines, corresponding complex functions are considered of which the real parts are the original quantities. For a sine wave of a given frequency, the absolute value |z| of the corresponding z is the amplitude and the argument arg (z) the phase. If Fourier analysisis employed to write a given real-valued signal as a sum of periodic functions, these periodic functions are often written as complex valued functions of the form ω f (t) = z where ω represents the angular frequency and the complex number z encodes the phase and amplitude as explained above. Improper integrals In applied fields, complex numbers are often used to compute certain real-valued improper integrals, by means of complex-valued functions. Several methods exist to do this; see methods of contour integration. Residue theorem The residue theorem in complex analysisis a powerful tool to evaluate path integrals of meromorphic functions over closed curves and can often be used to compute real integrals as well. It generalizes the Cauchy and Cauchys integral formula. The statement is as follows. Suppose U is a simply connected open subset of the complex plane C, a1,, an are finitely many points of U and f is a function which is defined and holomorphic on U\{a1,,an}. If ÃŽ ³ is a rectifiable curve in which doesnt meet any of the points ak and whose start point equals its endpoint, then Here, Res(f,ak) denotes the residue off at ak, and n(ÃŽ ³,ak) is the winding number of the curve ÃŽ ³ about the point ak. This winding number is an integer which intuitively measures how often the curve ÃŽ ³ winds around the point ak; it is positive if ÃŽ ³ moves in a counter clockwise (mathematically positive) manner around ak and 0 if ÃŽ ³ doesnt move around ak at all. In order to evaluate real integrals, the residue theorem is used in the following manner: the integrand is extended to the complex plane and its residues are computed (which is usually easy), and a part of the real axis is extended to a closed curve by attaching a half-circle in the upper or lower half-plane. The integral over this curve can then be computed using the residue theorem. Often, the half-circle part of the integral will tend towards zero if it is large enough, leaving only the real-axis part of the integral, the one we were originally interested Quantum mechanics The complex number field is relevant in the mathematical formulation of quantum mechanics, where complex Hilbert spaces provide the context for one such formulation that is convenient and perhaps most standard. The original foundation formulas of quantum mechanics the Schrà ¶dinger equation and Heisenbergs matrix mechanics make use of complex numbers.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  The quantum theory provides a quantitative explanation for two types of phenomena that classical mechanics and classical electrodynamics cannot account for: Some observable physical quantities, such as the total energy of a black body, take on discrete rather than continuous values. This phenomenon is called quantization, and the smallest possible intervals between the discrete values are called quanta (singular:quantum, from the Latin word for quantity, hence the name quantum mechanics.) The size of the quanta typically varies from system to system. Under certain experimental conditions, microscopic objects like atoms or electrons exhibit wave-like behavior, such as interference. Under other conditions, the same species of objects exhibit particle-like behavior (particle meaning an object that can be localized to a particular region ofspace), such as scattering. This phenomenon is known as wave-particle duality. Application of complex number in Computer Science. Arithmetic and logic in computer system Arithmetic and Logic in Computer Systems provides a useful guide to a fundamental subject of computer science and engineering. Algorithms for performing operations like addition, subtraction, multiplication, and division in digital computer systems are presented, with the goal of explaining the concepts behind the algorithms, rather than addressing any direct applications. Alternative methods are examined, and explanations are supplied of the fundamental materials and reasoning behind theories and examples. Recticing Software engineering in 21st century This technological manual explores how software engineering principles can be used in tandem with software development tools to produce economical and reliable software that is faster and more accurate. Tools and techniques provided include the Unified Process for GIS application development, service-based approaches to business and information technology alignment, and an integrated model of application and software security. Current methods and future possibilities for software design are covered. In Electrical Engineering: The voltage produced by a battery is characterized by one real number (called potential), such as +12 volts or -12 volts. But the AC voltage in a home requires two parameters. One is a potential, such as 120 volts, and the other is an angle (called phase). The voltage is said to have two dimensions. A 2-dimensional quantity can be represented mathematically as either a vector or as a complex number (known in the engineering context as phasor). In the vector representation, the rectangular coordinates are typically referred to simply as X and Y. But in the complex number representation, the same components are referred to as real and imaginary. When the complex number is purely imaginary, such as a real part of 0 and an imaginary part of 120, it means the voltage has a potential of 120 volts and a phase of 90 °, which is physically very real. Application in electronics engineering Information that expresses a single dimension, such as linear distance, is called a scalar quantity in mathematics. Scalar numbers are the kind of numbers students use most often. In relation to science, the voltage produced by a battery, the resistance of a piece of wire (ohms), and current through a wire (amps) are scalar quantities. When electrical engineers analyzed alternating current circuits, they found that quantities of voltage, current and resistance (called impedance in AC) were not the familiar one-dimensional scalar quantities that are used when measuring DC circuits. These quantities which now alternate in direction and amplitude possess other dimensions (frequency and phase shift) that must be taken into account. In order to analyze AC circuits, it became necessary to represent multi-dimensional quantities. In order to accomplish this task, scalar numbers were abandoned andcomplex numberswere used to express the two dimensions of frequency and phase shift at one time. In mathematics, i is used to represent imaginary numbers. In the study of electricity and electronics, j is used to represent imaginary numbers so that there is no confusion with i, which in electronics represents current. It is also customary for scientists to write the complex number in the form a+jb. In electrical engineering, the Fourier transform is used to analyze varying voltages and currents. The treatment of resistors, capacitors, and inductors can then be unified by introducing imaginary, frequency-dependent resistances for the latter two and combining all three in a single complex number called the impedance. (Electrical engineers and some physicists use the letter j for the imaginary unit since i is typically reserved for varying currents and may come into conflict with i.) This approach is called phasor calculus. This use is also extended into digital signal processing and digital image processing, which utilize digital versions of Fourier analysis (and wavelet analysis) to transmit, compress, restore, and otherwise process digital audio signals, still images, andvideosignals. Introduce the formula E = I à ¢Ã¢â€š ¬Ã‚ ¢ Z where E is voltage, I is current, and Z is impedance. Complex numbers are used a great deal in electronics. The main reason for this is they make the whole topic of analyzing and understanding alternating signals much easier. This seems odd at first, as the concept of using a mix of real and imaginary numbers to explain things in the real world seem crazy!. To help you get a clear picture of how theyre used and what they mean we can look at a mechanical example We can now reverse the above argument when considering a.c. (sine wave) oscillations in electronic circuits. Here we can regard the oscillating voltages and currents as side views of something which is actually rotating at a steady rate. We can only see the real part of this, of course, so we have to imagine the changes in the other direction. This leads us to the idea that what the oscillation voltage or current that we see is just the real portion of a complex quantity that also has an imaginary part. At any instant what we see is determined by aphase anglewhich varies smoothly with time. We can now consider oscillating currents and voltages as being complex values that have a real part we can measure and an imaginary part which we cant. At first it seems pointless to create something we cant see or measure, but it turns out to be useful in a number of ways. It helps us understand the behaviour of circuits which contain reactance (produced by capacitors or inductors) when we apply a.c. signals. It gives us a new way to think about oscillations. This is useful when we want to apply concepts like the conservation of energy to understanding the behaviour of systems which range from simple a mechanical pendulums to a quartz-crystal oscillator. Applications in Fluid Dynamics Influid dynamics, complex functions are used to describe potential flow in two dimensions. Fractals. Certain fractals are plotted in the complex plane, e.g. the Mandelbrot set Fluid Dynamics and its sub disciplines aerodynamics, hydrodynamics, and hydraulics have a wide range of applications. For example, they are used in calculating forces and moments onaircraft, the mass flow of petroleum through pipelines, and prediction of weather patterns. The concept of a fluid is surprisingly general. For example, some of the basic mathematical concepts in traffic engineering are derived from considering traffic as a continuous fluids. Relativity Inspecialandgeneral relativity, some formulas for the metric onspacetimebecome simpler if one takes the time variable to be imaginary. (This is no longer standard in classical relativity, but isused in an essential wayinquantum field theory.) Complex numbers are essential tospinors, which are a generalization of thetensorsused in relativity. Applied mathematics In differential equations, it is common to first find all complex roots r of the characteristic equation of a linear differential equation and then attempt to solve the system in terms of base functions of the form f(t) = ert. In Electromagnetism: Instead of taking electrical and magnetic part as a two different real numbers, we can represent it as in one complex number In Civil and Mechanical Engineering: The concept of complex geometry and Argand plane is very much useful in constructing buildings and cars. This concept is used in 2-D designing of buildings and cars. It is also very useful in cutting of tools. Another possibility to use complex numbers in simple mechanics might be to use them to represent rotations.

The Problem of Evil Essay -- essays research papers

I do not believe that evil—as we typically understand it—exists in the world. I believe that what we perceive as evil is simply our misdirected use of the good that God provides. The reason that we even have an experience of perceived evil is because for the soul to experience itself as any particular thing, the exact opposite of that thing must come into the space. In other words, in this relative existence, hot cannot be hot without cold, tall cannot be tall without short, and you cannot be you without that which is not you. So I believe that what we call evil is just the opposite end of the spectrum of good, not something separate. Following this line of thought, the next step our logical minds would take, it would seem that in order for God to experience Itself as the all-consuming good, there had to be something called the all-consuming evil. Wrong! There is only God. God is all there was, all there is, and all there ever will be. Yet God wished to know Itself in Its own experience. Logically speaking, that which is divine cannot know and experience Itself except in the presence of that which is not divine. The problem is that which is not divine does not exist. So, since we have the power to create anything, we have simply called it forth through our thought process. That is to say we have imagined it. All religions—and philosophies—must wrestle with the problem of evil. We can look all around the world and see what we would clearly label as evil. Many say, therefore, ...

Ray Bradbury :: Essays Paper s

Ray Bradbury No name typifies science fiction to the American public more than the name Ray Bradbury. For over forty years, he has been writing novels, short stories, poems, plays, and movie scripts that have long since kept him in the forefront of American literature. His stories become standard reading for many high school and college students. His literary style can best be described as "enchantment;" the way he captivates his readers with charm, bewitchment, and stunning verbal evocations. His visions of the past, future, and the present delight his readers. His books are virtually long-time bestsellers and have been translated into over twenty languages. He is quite popular in the former Soviet Union. However, success did not come easily for Bradbury. He inched away at his writing career, crafting story after story, until he was selling and occasional short story for half a cent per word. Much of his childhood, and a little of his adulthood, inspired his writings. In this paper, these influences as well as his method of drawing the reader into a story will be discussed. Perhaps the most important influence in Bradbury's youth was his discovery of magic. The famous Blackstone the Magician once included Bradbury in his act, and it enchanted him. The most influential magician on Bradbury was Mr. Electrico. Bradbury wrote about his experience with Mr. Electrico and stated that Mr. Electrico would sit every night in his electric chair, brushing his Excalibur sword over the audience, sparking them with lightning, and crying, "Live forever!" A few weeks after Bradbury encountered Mr. Electrico, he began writing his first short stories. In July of 1941, Bradbury sold his first story to Super Science Stories. Although he only made $13.75 on the sale, he rejoiced. Within a year from that sale, he was a full-time writer. The Martian Chronicles, his first novel, was published within a decade and he soon found himself famous. Fahrenheit 451 marked a new point in Bradbury's writing style - the pessimistic side of life, where he discussed a future where mankind isslowly destroying itself. The sense of what is best in America and what is best for the American people and humanity as a whole, is another thing that fuels his literature. He writes on topics relevant to what is happening in society. Mars and book burning are a couple of them.

Addiction: A Desease Or A Choice? :: Drugs Alcohol

People argue whether drug addiction is a disease or a choice. Today, I will be discussing this argument in hopes to have a better understanding as to why this topic is so controversial. Throughout my research, I easily found information on this topic and I am still not sure I have found any answers. The biggest argument is that addiction is a choice not a disease. For those on the other side of the argument they claim just the opposite. According to a source on the Internet entitled Alcohol and Drug Treatment: The Disease Concept Of Substance Abuse and Addiction, the idea of drugs and alcohol being a disease is a â€Å"very controversial and debated topic.† For the purposes of this essay, I am forced to agree that drug addiction is a choice. People get high and drink because they want to and if they are not careful they can become an addict. The research I found on this particular topic seemed to have the most support and facts to dismiss the idea that addiction is a disease. I also beeivle if there was enough evidence to support the idea of addiction being a disease it would not be such a controversial topic. According to a Website entitled â€Å"Saint Jude Retreat House,† alcoholism and drug addiction are not diseases because those types of behaviors can be avoided and there is help available to change these behaviors. Although it has been found true that drug and alcohol dependency can be passed down through hereditary there is no concrete evidence I have found that proves that this is a disease. In a book entitled Treating Substance Abuse, Theory and Technique 2nd edition, says â€Å"This first and probably least controversial of the disease models can be termed the â€Å"medical consequences model.† (Page 11). This statement seems to be saying that because this topic is so controversial and not enough medical proof is available it has been given a generic name. It is true that drugs and alcohol can cause diseases, but does that make the addiction problem a disease? Perhaps this topic is so controversial because of the lack of knowledge or understanding of drug addiction. On a Website entitled â€Å"Addiction is a Chronic Disease,† the source was comparing diabetes and cancer to support their idea that drug addiction to is a chronic disease. The Website did not give any additional support and provided no examples. Addiction: A Desease Or A Choice? :: Drugs Alcohol People argue whether drug addiction is a disease or a choice.

Sociology Marriage and Divorce

Sociology – Family Unit – Marriage and Divorce Most people argue that the family is in ‘crisis’. They point to the rapidly increasing divorce rate, cohabitation, illegitimacy and number of single parent families. What is happening to Marriage? Marriage has increased in popularity, reaching a peak in 1971. Since then there has been a significant decline in the number of marriages, from 459000 in 1971 to 250000 in 2001. There is a decline in first marriages where neither partner has been married before.But there is a growing number of remarriages, in which one or both partners have been divorced; these marriages constitute 15% of all marriages in 1971 and 40% in 1996. The average age at which people first marry has steadily increased in recent decades. Since 1971 it has risen from 24 to 30 for men and from 22 to 28 for women. By 1998 there were relatively few young people who were married. Of those under the age of 24 just 3% of men and 7% of women were marri ed. More than one third of all 18 – 49 year old women are now single.Is Marriage still the Norm? Despite all the arguments about the decline of marriage, it continues to be the case that most people in Britain grow up and form a nuclear family for part of their adult life. Most couples who get married or have stable cohabitation relationships have children. The family unit is still mainly one in which children are brought up by two ‘parents’. The majority (71%) of young people live in families headed by a couple. Just less than a quarter (24%) live in single parent households.The majority of lone-parent families (90%) are headed by women, and the major reason is separation or divorce from the male partner, although some women are single or widowed. Cohabitation is most likely to be found among those aged 25 – 34 years. Over one in five (22%) in this age group currently cohabit. The majority (59%) of those who live together subsequently go on to marry that partner. In some respects marriage is more popular because people marry more often. The percentage of remarriage has risen from 14% in 1961 to 40% in 1996. Cohabitation Living together as a couple is no longer seen as ‘living in sin’. Read also  Sociology and Social Integration.Increasingly the idea of cohabiting is being viewed as respectable. Two thirds (67%) of the British public now regard cohabitation as acceptable, even when the couple have no intention in getting married. The idea that people should get married if they have children is also fading away. In 1989, 7 in 10 people held this view. By 2001 the proportion had fallen to just over half (54%). Nor is there much support these days for the belief that married couples make better parents – only 1 in 4 (27%) think this is the case. Marriage Patterns for African-Caribbean’s and AsiansResearch carried out at Essex University in 2000 indicates that only 39% of British-born African-Caribbean adults under the age of 60 are in a formal marriage compared with 60% of white adults. Moreover this group is more likely than any other group to inter-marry. The number of mixed-race partnerships means that very few African-Caribbean men and women are ma rried to each other. Only one quarter of Caribbean children live with two black parents. There is also a tradition of women living independently from their children’s father in the African-Caribbean community.This could be partly explained historically, from the days of slavery, when husbands and wives were sold to separate plantations. But Wilson (1987) argues that a black woman may be reluctant to marry (or live with) a man whose chances of getting / keeping a job are low and make him an unreliable source of income for themselves and their children. Consequently half of Caribbean families with children are now single parents. Marriage in Asian families whether Muslim, Hindu or Sikh is mainly arranged and consequently there is little inter-marriage with other religions or cultures.Relationships between Asian parents and their children are also very different, Asian children tend to respect religious and cultural traditions and they feel a strong sense of duty to their famili es and especially their elders. Taken as a whole young British Asians have more choice and say than previous generations. Their current situation is probably not dramatically different from that of young no-Asian adults who, while choosing their marital partners on the basis of romantic love, often marry people very similar to themselves in terms of background factors such as social class and educational qualifications.Parental influence may be less direct than in an arranged marriage, but parents can show disapproval on ‘inappropriate’ boyfriends or girlfriends. What are the Patterns in Divorce? From 1971 to 1996 the number of divorces has more than doubled. In 1991 there were 350000 marriages but 171000 divorces meaning that there were nearly half as many divorces as marriages. The proportion of marriages, which are remarriages, has also been rising, for example 15% of all marriages in 1961 were re-marriages for one or both partners; by 1991 this figure has risen to 3 6%.Britain has the highest divorce rate in Europe according to official EU statistics (Eurostat, June 2001). Each year, 2. 7 people per thousand of the population get divorced in Britain compared with the EU average of 1. 8 per thousand. Who Divorces? Young spouses and young marriages are most at risk. A person’s age at marriage is strongly associated with the likelihood of divorce. Generally speaking, the older people are when they marry, the less chance they have of divorcing. Couples who marry in their teens are almost twice as likely to divorce as those who marry between the ages of 20 and 24.The divorce rate also varies by the amount of time the marriage has lasted. For example, in 1979 nearly half of all divorces occurred within the first 10 years. One investigation (Thornes and Collard, 1979) found that of all marital separations (rather than legal divorces), 60% occurred before the 10th year of marriage. Social class is also closely related to the incidence of divorce . The divorce rate for unskilled husbands is more than four times that for professionals and for the unemployed, almost five times that for the professionals.Patterns in Marriage and Divorce Feminist sociologists see the trends as a sign of the lack of satisfaction provided by traditional patriarchal marriage, with individuals seeking alternative types of relationships and living arrangements. New Right thinkers have seen the trends as a sign of the breakdown of the family and have argued for a return to ‘traditional values’. They suggest that because of the easy availability of divorce, people are no longer as committed to the family as they were in the past.Changes in legislation which have made divorce easier but also social changes in which the law reflect are seen as the main causes of the increase in divorce rates. Have Women Broken up the Family? The position of women has changed in a number of ways, such as the wife does not have to put up with an unsatisfactory marriage; they are not expected to be socially subservient to their husbands. Women now have more independence and are in a better financial position if they were to want a divorce; they are no longer totally reliant on their husbands.It was stated that women in general are less satisfied with their marriages than men. In the 1990’s women initiated the majority of divorces. Growing Secularisation Secularisation refers to the declining influence of religious beliefs and institutions. Goode and Gibson argued that secularisation has resulted in marriage becoming less o a sacred, spiritual union and more a personal and practical commitment. Evidence that supports this is that 60% of marriages today do not involve a religious ceremony. Changing Social AttitudesDivorce has become more socially acceptable and there is less social disapproval and stigma attached to divorces. It no longer hinders careers through a public sense of scandal and outrage. As a result of this people are le ss afraid of the consequences of divorce and are more likely to end an unhappy marriage. Functionalists such as Talcott Parsons and Renoald Fletcher argue that the increased value of marriage may have caused a rise in marital breakdown. As people expect and demand more from a marriage and expect it to be perfect.Fletcher argues that a relatively high divorce rate may be indicative not of lower but of higher standards of marriage in society. Privatised Marriages Allan argues that the family has become increasingly defined as a private institution. The wider family, and society at large, do not have the right to interfere in family life and therefore the family unit is not supported by its integration into a wider social network, which means family problems cannot be so easily shared. Love and Marriage – Why are Arranged Marriages Stronger? Within an arranged marriage people have more realistic expectations than those who marry for love.People who support arranged marriages sug gest that love is something that develops overtime, where as romantic love is likely to change into something less exciting, or disappear altogether Sociology – Family Unit – Births and The Ageing Population Births One of the strongest trends has been the rise in illegitimacy. Illegitimacy rates are rising, as more people have children without being married. Some of the stigma associated with illegitimacy no longer exists. This is countered by the New Right’s assault on unmarried mothers, who have been the scapegoat to a certain extent by the media who blame them for the modern failings of society.Unmarried mothers may not be that different to nuclear families as some of these children born outside of a marriage are born to a couple who cohabit or are in a stable relationship, so will therefore have the same advantages / life as a nuclear family child. It is just that the mother and father / couple are not legally married. More and more women are deciding not to have children, as they’d rather focus on / have a career. Having a career may also be the reason for women having children later on in their lives. The Ageing PopulationThe population as a whole are getting older as people are now living longer. This could be seen as a negative or a positive thing. According to the negative view this gives a greater dependence ratio whereby the working population have a greater burden to take care of those not working. Increased pressure on hospitals, social services and pensions will lead to a greater tax burden. On the positive side, it can be argued that since older people are now more likely to stay fit and healthy they may become an important part of our families (childcare for grandchildren) and as part of the voluntary workforce.Ginn and Arber found that the level to which older people could maintain their independence and play a constructive part in society depended to a large extent on their social class, gender and ethnicity. The n otion of ageing itself is a socially constructed concept that varies from culture to culture. The retirement age itself has moved several times and still varies between men and women reinforce the notion that old age is in itself a social construction.

Kite Festival

Rino Bnao EN 101-4 Karen Millam Sep 14, 2012 Taiwanese Kite Festival Kite Festival is the event where people made different kind of kites to fly them. Few days ago I went to Delap to attend the kite festival. I really enjoyed the event and although there are many reasons why I like about the kite Festival, few major facts why I like the event the most and catches my attention. First reason why I like the event is that the Taiwanese allowed the kids to fly and played their kites. Each kid that I saw during the event was really happy.They enjoyed playing with the different kind of kites. The Taiwanese even gave the kids each a small kite that they can play with it and fly it around and enjoyed the day. Another reason why I like the event is the Kites. There are about ten to fifteen kites that flying in the air. Each kite shape like different kind of animals and that one thing that catches my attention. I even asked myself why is all the kites shape like an animal. Later on after interv iewing or talking with one of the team member, I found out that an animal is the best shape that they used.He said that the every entire kite they fly will always be an animal’s shape. Each kite has different kind of color and they look bright with their color. Finally I like the event because I learn something from it. First thing that I learn is how to make it and what materials that used to make a kite. According to them, Bamboo stick and silk is the best material to make a kite. They show us how they made it and it was really awesome seeing them making a kite for the kids.I also learn that the event is really important because they bring back the Taiwanese or Chinese history and of course bring flying sport to Marshall Island. Also learned what are the kite for and there are many things that they can use for the kite. For example they used the kite for sport and also for war. Small or big kites can be both useful for many reasons. In conclusion, I really admired the color ful kites that surrounded me. I enjoyed the event because I learn good thing about kite and how useful, colorful, awesome they are. This entire thing catches my attention. I was surprise when I saw them.

Anchoring-Annual Day Essay

These virtual characters then do things that people in the real world do, such as having sex. Depending on your preferences, you can have sex with someone who is older or younger than you – perhaps much older or younger. In fact, if your virtual character is an adult, you can have sex with a virtual character who is a child. If you did that in the real world, most of us would agree that you did something seriously wrong. But is it seriously wrong to have virtual sex with a virtual child? Some Second Life players say that it is, and have vowed to expose those who do it. Meanwhile, the manufacturers, Linden Labs, have said they will modify the game to prevent virtual children from having sex. German prosecutors have also become involved, although their concern appears to be the use of the game to spread child pornography, rather than whether people have virtual sex with virtual children. Laws against child pornography in other countries may also have the effect of prohibiting games that permit virtual sex with virtual children. In Australia, Connor O’Brien, chair of the criminal law section of the Law Institute of Victoria, recently told the Melbourne newspaper The Age that he thought the manufacturer of Second Life could be prosecuted for publishing images of children in a sexual context. The law is on solid ground when it protects children from being exploited for sexual purposes. It becomes much more dubious when it interferes with sexual acts between consenting adults. What adults choose to do in the bedroom, many thoughtful people believe, is their own business, and the state ought not to pry into it. If you get aroused by having your adult partner dress up as a schoolchild before you have sex, and he or she is happy to enter into that fantasy, your behavior may be abhorrent to most people, but as long as it is done in private, few would think that it makes you a criminal. Nor should it make any difference if you invite a few adult friends over, and in the privacy of your own home they all choose to take part in a larger-scale sexual fantasy of the same kind. Are computers linked via the Internet – again, assuming that only consenting adults are involved – so different from a group fantasy of this kind? When someone proposes making something a criminal offense, we should always ask: who is harmed? If it can be shown that the opportunity to act out a fantasy by having virtual sex with a virtual child makes people more likely to engage in real pedophilia, then real children will be harmed, and the case for prohibiting virtual pedophilia becomes stronger. But looking at the question in this way raises another, and perhaps more significant, issue about virtual activities: video game violence. Those who play violent video games are often at an impressionable age. Doom, a popular violent videogame, was a favorite of Eric Harris and Dylan Klebold, the teenage Columbine High School murderers. In a chilling videotape they made before the massacre, Harris says â€Å"It’s going to be like fucking Doom†¦. That fucking shotgun [he kisses his gun] is straight out of Doom! There are other cases in which aficionados of violent videogames have become killers, but they do not prove cause and effect. More weight, however, should be given to the growing number of scientific studies, both in the laboratory and in the field, of the effect of such games. In Violent Video Game Effects on Children and Adults, Craig Anderson, Douglas Gentile, and Katherine Buckley, of the Department of Psychology at Iowa State University, draw these studies tog ether to argue that violent video games increase aggressive behavior. If criminal prosecution is too blunt an instrument to use against violent video games, there is a case for awarding damages to the victims, or families of the victims, of violent crimes committed by people who play violent video games. To date, such lawsuits have been dismissed, at least in part on the grounds that the manufacturers could not foresee that their products would cause people to commit crimes. But the evidence that Anderson, Gentile, and Buckley provide has weakened that defense. Andre Peschke, editor-in-chief of Krawall. e , one of Germany’s leading online computer and video game magazines, informs me that in ten years in the video game industry, he has never seen any serious debate within the industry on the ethics of producing violent games. The manufacturers fall back on the simplistic assertion that there is no scientific proof that violent video games lead to violent acts. But sometimes we cannot wait for proof. This seems to be one of those cases: the risks are great, and outweigh whatever benefits violent video games may have. The evidence may not be conclusive, but it is too strong to be ignored any longer. The burst of publicity about virtual pedophilia in Second Life may have focused on the wrong target. Video games are properly subject to legal controls, not when they enable people to do things that, if real, would be crimes, but when there is evidence on the basis of which we can reasonably conclude that they are likely to increase serious crime in the real world. At present, the evidence for that is stronger for games involving violence than it is for virtual realities that permit pedophilia.

Hunted – Creative Writing

It was a cold, wet, December night and Macauley Taylor was casually strolling down the long, dark, winding lane, on this way back from a tiring football practice. He could feel his legs aching as he walked, having been crudely taken out towards the end. He just wanted to get home. Suddenly, three men appeared out of nowhere, at the end of the road. Macauley recognised these three men. â€Å"This is bad,† he thought to himself as he tentatively stepped nearer to them. Relief. He had successfully waded his way past the little huddle the men had made, with all his bones intact. All of a sudden, there was a shout of, â€Å"Get him!† and Macauley had three huge figures gunning him down. He could smell their foul putrid breath behind him. He could taste the hate in the words billowing from their mouths. He was running as fast as his tender feet would carry him. A warehouse gradually came into view through the dank darkness. He ran towards it, making quick, unexpected changes in the direction he was going, hoping to shake one of his pursuers off. He did this successfully and, before long, had found an empty storage compartment and hid in there, hoping none of them had seen him. He heard the three of them walking around, shouting his name, telling him that if he came out now, it wouldn't be half as bad for him as it would be if they had to find him. He was praying they wouldn't find him, as he quite liked his legs how they were. With all the bones NOT BROKEN. He could tell they were moving further away from him, as their voices were getting more and more distant. He was wondering about maybe making an escape sooner, and risk getting caught, or later. He knew his mother would be getting extremely worried about him as he normally got home around an hour ago. He made his mind up. Get home. He moved soundlessly to the door of the compartment and moved his head around the door. Luckily, no one was close and he was able to slide out and find his way back onto the country road. He'd made it. Safety. Thanking his lucky stars, Macauley made his way up the road. *BANG* A gunshot hit the night sky like the crack of a whip. Macauley sank down his knees, not in pain, in pure shock. He could feel blood pouring down his back as if someone had poured a glass of water down the back of his top. His whole life flashed before his eyes like one of those old drive-in movies. He thought of the things he regretted; things that were said, things that weren't†¦ He wished his mum were there, just so he could tell her how much he loved her. Just once. He never showed her how much he meant to her. Swiftly, a bright, tunnel of light emerged in front of him. Standing at the entrance of the tunnel, was his Dad. The Dad: who had died a year before. The Dad: who Macauley had spent every night of the following six months crying for, begging him to come back, to not leave him. The Dad: who was Macauley's hero in every walk of life was now here. Standing right in front of him. He said to him, â€Å"Don't be scared, son, it's all all right now†. He cautiously tiptoed towards him, then ran, then sprinted in the direction of his idol. He reached the end of the tunnel, and with it, came the end of his life on Earth.

Ethics Theories Table Essay Example | Topics and Well Written Essays - 500 words

Ethics Theories Table - Essay Example An employee entrusted with funds by his or her corporation is dutybound to account for these funds and remit the balance, if any. Even though this honesty may deprive him of certain material comforts, i.e., the extra money if unremitted could have bought him or her a new car, duty-based ethics prescribes that he or she should return the money. The classic goal-based theory is utilitarianism. Jeremy Bentham presented one of the earliest fully developed systems of utilitarianism. Two features of his theory are noteworty. First, Bentham proposed that we tally the consequences of each action we perform and thereby determine on a case by case basis whether an action is morally right or wrong. This aspect of Bentham's theory is known as act-utilitiarianism. Second, Bentham also proposed that we tally the pleasure and pain which results from our actions. For Bentham, pleasure and pain are the only consequences that matter in determining whether our conduct is moral. This aspect of Bentham's theory is known as hedonistic utilitarianism. An employee should strive to get a promotion at all costs as this will benefit him, even at the expense of co-employees and even if there would be a violation of a moral duty in the process. For example, the moral duty to give credit where credit is due after a successful project. The most influe

How Brands Win by Listening Assignment Example | Topics and Well Written Essays - 250 words

How Brands Win by Listening - Assignment Example The customers are well informed, and most of them are on the social media. Using the social media to sell the brand will not only upturn the company’s sales but will also enable the company to identify areas that need improvements. In this regards, the power of listening through social media stands out to be one of the effective marketing strategies in the 21st Century. How do marketing managers engage with the consumers and how brands can capitalize on the power of listening are important factors that every business should focus on as stated by Jeff. The power of social marketing on improving the brand is not just a theoretical aspect or rather a practical one. Jeff Bodzewsk gave several examples to highlight this point. However, the example of Nissan stands out to be a great example on the importance social marketing. Nissan had not been getting the best reviews on the social media regarding their brands. Their reaction was quite splendid. They took this positively, and they listened to consumers’ opinions and integrated them into improving their brand. The fact that they did that through social media is the outstanding fact. Since this presentation was released in 2010, several companies have engaged in a â€Å"listening strategy†. For example, Samsung has improved its brands tremendously by launching different kinds of brands of its smartphones. The power of social marketing has played a vital role in this process. That is; Samsung uses social media to determine tastes and preferences of its customers. Thereafter, it produces brands that satisfy those taste and preferences. Jeff Bodzewsk’s advice on the power of listening is an important business aspect that every business entity should implement. Companies such as General Motors Ltd should implement this strategy. This is because General Motors has not been active on social media. It is not enough to just start the conversation, but a firm should go
