Summary An Economic way of looking at life by Gary Becker Essay

Summary An Economic way of looking at life by Gary Becker - Essay Example Economic way of looking at life helps individuals to know moral pathways and how to be ethical in economics. In chapter 7, social issues that are discussed are termed as labor supply, which in it you find household production, the family, and the life cycle which can be well analyzed by economic way of looking at life. In making household decisions, certain factors have to be in mind. Some of these factors are, the economy, time, income and individuals involved. In household decision making, one of the key attribute is the size. For instance the size of the family and number of children dictate the economic way of living of that family. Often, women in society have a role in bearing and raising a certain number of children and carrying out farm works as opposed to men who work in outside jobs in various offices. Economic analysis of this kind of decision shows that the labor force is low compared to the size of the family. This is because, the income from the couple would be more compared to when only the male individual is working. If the latter is used it would mean poor living standards as the family is growing. As regards to whether families uses more by consuming purchased goods as opposed to home made goods also differs if we analyze using our knowledge on economic way of looking at life. Although there is no such a big difference between the two, if things such as labor and the time spent to produce the home made goods are considered, economic wise consuming household good will carry the day since leisure is achieved and no supervision when producing them. In a later age, household decision on when to retire comes in. The topic about taking care of yet grown up children and on the other hand, older children taking care of the aged parents is dominant. These two are interconnected and each of them is crucial and important. Analysis of this economically

Management Research Reports- Labour turnover, hospitality Essay

Management Research Reports- Labour turnover, hospitality - Essay Example Apart from these, there is lack of coordination between the industry and the educators due to which both the students that enter the work field and the industry, experience a gap. Conclusions have been drawn extensive study. The business environment today is turbulent and challenging. The hotel industry is characterized by low job security, low pay, shift duties and limited opportunities for promotion (Wong, Siu & Tsang, 1999), no breaks, fluctuating demand, simultaneous production and consumption (Birdir, 2002). The sector offers a range of contradictions on a daily basis (Baum & Nickson, 1998). Human capital is considered the greatest asset in meeting these challenges and gaining competitive edge. However, attracting, managing and retaining talent in the hospitality industry is the biggest challenge. Competitive advantage relies on service quality and delivery of service quality itself has become challenging due to high staff turnover in the industry. The industry does realize that high turnover of staff ultimately results in high recruitment and training costs but despite all efforts they have not been able to bring about changes in the situation. High turnover indicates that staff is not sufficientl y motivated to work for the organization. This in turn implies lack of commitment and loyalty from the employees. Since this is an issue that concerns the smaller as well as the larger firms in the industry, this requires an in-depth study. Various studies have been conducted in the past but most studies have focused on one particular issue or one particular region. This study proposes to be an umbrella study where all the various factors that cause high turnover will be looked into. High labour turnover is not a country-specific problem but is a global problem. This study would provide greater insight than is possible in one

Effects Of Digital Technology On Identity

Effects Of Digital Technology On Identity Identity is described as a sense of self, as being a consistent and unique person. (Fernald, 1997) Defining individual identity involves being aware of and understanding an individuals experiences, perceptions, feelings, sensations, images and memories. Ones understanding and explanation of them, the choices and decisions a person makes, and the action they take in responding to changing conditions, needs, demands and challenges is another important aspect of identity. Beyond their mental and physical constitution, human beings consist of personal experiences, perceptions, feelings, images and memories (Dorscht, 1998). As digital technology is a vast area to cover, I will primarily focus on the internet and peoples ability to connect with others. Paul Magnarella, of the University of Florida proposes that, as societies become more complex and differentiated, due to technological developments, more specialists are needed, and social integration is becoming based on the interdependence of specialized functions (Magnarella, 1997). Modern humanity is adjusting to life within the global community. This has far reaching impact in how personal, social and cultural identities are formed and maintained. As the technology of the twenty-first century speeds up and expands access to information and virtual environments, constraints upon individuals to exclusively rely upon, and respond to their local physical environment is diminished (Jones, 1997). The availability of information and technology has affected the development of individual and group identity. It is only very recently in the time line of human evolution, that individuals and members of society have been exposed to cultures, attitudes and ways of thinking that are not insulated. There has been a great deal of attention paid to the development of self in this technological society. The volume and variety of relationships now available to the average person, through the Internet, at an interpersonal level, enables the individual an opportunity to construct a new self or identity for every occasion, with very little is expected in return (Eyck, 1998). Sociology is the study of human behaviour in groups, and focuses on the influences of social relationships on attitudes and behaviour. In the Sociological Research Online Journal, Schroeder examines the social aspects of multi-user virtual reality. He states that there is stratification in cyber-space communities, with insiders and outsiders with different behaviours, roles, and statuses. Schroeder regards the possibilities for extending new opportunities and experiences in both the natural and social worlds as sociologically relevant (Schroeder, 1997). The way in which individuals perceive themselves and their place in the world, is fundamental to the topic of identity. Researchers have described control as an individuals belief that they could cause good or bad events. (Shapiro et al.) The schema theory is described as facts or experiences that are clustered around topics, which provide a frame of reference for individuals to draw upon when making judgments (Wresch, 1996). When an individual combines this schema with the way they selectively value the limited information allowed into their consciousness, it further defines ones sense of identity. One point proposed is, that by role-playing or testing scenarios in cyber-space, some people are better prepared to function in similar real life situations. Another issue is that of gender switching on the web. Anthropologists describe gender as the cultural elaboration and meaning assigned to the biological differentiation between the sexes (Haviland, 1997), in the sense that ones sex is biologically determined, but ones sexual identity is culturally assigned. In sociological terms, gender roles are expectations, regarding the proper behavior and activities, and attitudes of males and females. (Schaefer Lamm, 1997: 37) In cyber-space you can assume multiple identities, change gender and explore different facets of your personality. Turkle quotes Jung, saying Jung believed that for each of us, it is potentially most liberating to become acquainted with our dark side, as well as the other-gendered self, called anima in men and animus in women (Turkle, 1995). In role-playing and gaming, such as the online fantasy game, Second Life. It may be seen as an exercise in fantasy, and a way to create and gain mastery over a persona the individual is in control of. Second Life is a free 3D virtual world where users can socialize, connect and create using free voice and text chat. One definition of society is a fairly large number of people who live in the same territory, are relatively independent of people outside it, and participate in a common culture (Schaefer Lamm, 1997). In cyber-space, people are forming virtual societies. A sense of familiarity and belonging is created, through interaction and virtual proximity. Participants in Second Life refer to their virtual communities as cultures. Culture by definition is, A set of rules or standards, shared by members of a society, which when acted on by the members produce behaviour that falls within a range of variation the members consider proper and acceptable (Haviland, 1997). To deviate from the rules can result in punishment or expulsion from the culture. There are both IC, in character, guidelines for behavior, and OC or out of character codes to be followed. These people feel that they know each other. They interact both in and out of character and, in some cases have arranged meetings in the Real Wor ld. Sherry Turkle (Turkle, 1995) puts forward the idea that computer mediated communications have saturated society with both alien and local cultures. Turkle points out that through such widespread social contact, we are adjusting to and assimilating other cultures beliefs and norms to such an extent that we as a society are being deprived of traditional social structures and norms. In this information age, one may locate diverse friends, create an alternate identity and explore avenues of study and areas of culture that were never an option a generation ago (Turkle, 1995). Culture lag is defined as a period of maladjustment during which the non-material culture adapts to the material culture and foreign ideas are often viewed as threatening. (Schaefer Lamm, 1997) This definition could be paraphrased by stating that some individuals suffer from a period of confusion while the previously non-technical culture is adapting to new technology. This techno-culture lag appears to be more problematic to those who have not had as much experience with the technical and Internet related fields, than for example, the average secondary school student. The modern teenager sees the Internet in much the same way the children of the 1960s took television for granted. From a sociological view our individual culture provides us with a predisposed way of thinking and behaving when communicating. Our vocabulary is affected by our culture, in that we tend to have more words or ways of expressing ourselves, relative to the degree of importance we attach to a given subject. (Haviland, 1997) The way in which we communicate also guides our thinking and behaviour. This can be a potential source of problems when communicating outside our own culture. Phrases and words that are intended to convey a particular meaning may be misinterpreted and cause embarrassment or offense to a person of a different culture. The absence of body language and gestures when communicating by computer, whether through email or chats, seems to be guiding communication to a more generic form and adding a whole new vocabulary of technological terminology. Modern humanity is part of a networked society, whether directly or indirectly. Its views of the world, its cultures and individual identity are all being reshaped through the impact of the Internet in our lives. People have become cyber-chameleons, adjusting to whoever they are communicating with. This flexibility is characteristic of contemporary society. One generation ago, it was common for a person to be born, live, and die in one community, while being married to the same person and working in the same job. In todays society it is not unusual to change jobs, and move, remarry and adapt multiple times. Societies suffer a cultural loss when they homogenize and streamline their identities in order to communicate and interact globally (Featherstone Burrows, 1995). The modern self is bombarded with instantaneous images of far off peoples, events and cultures and distant happenings. This places the producers of this information in the position of becoming manufacturers of reality (Eyck, 1998). It is more important than ever that the individual become aware of how to distinguish fantasy from reality and evaluate the information that is being served up to them (Balsalmo, 1996). The distribution of knowledge and power has made it more difficult for powerful social institutions to wield the power they once did. Knowledge is power, so perhaps to spread knowledge is to distribute power. Ones awareness of choices and decisions, of action and responses, and understanding of what they indicate, and how they interact and relate is what finally comprises an image of oneself, an identity.

True Feelings in Billy Collins Taking Off Emily Dickinsons Clothes Es

True Feelings in Billy Collins' Taking Off Emily Dickinson's Clothes Upon first look, Billy Collins â€Å"Taking Off Emily Dickinson’s Clothes† seems to be a wild fantasy for Emily Dickinson that he is entertaining. Upon closer examination, however, the poem reveals his subconscious desire to have sex with his mother and his frustration about his inability to do so, resulting in the displacement of his sexual desires onto Dickinson. From the beginning, Collins is very detailed with his description. In fact he is quite anal retentive in explaining everything about the encounter. He starts from her outside clothing, â€Å"first, her tippet made of tulle† (1) and on through her mass of clothing until finally reaching her â€Å"corset† (41). Collins proclaims that the tippet is â€Å"easily lifted off her shoulders† (2), which lets people know that he is doing the work. Dickinson is simply standing there allowing him to touch and undress her. Perhaps this reflects that Collins is not often in control and never in control when it concerns his mother. He is probably constantly being told what to do, so it is very important that the reader realizes that he is in control of this situation. This may be why he projects Dickinson as immobile; he is simply projecting his inability to be in control onto Dickson. Collins then turns towards her â€Å"bonnet, the bow undone with a light forward pull† (4-5). The way he pulls the bonnet with a â€Å"light† (5) pulls shows how he feels it necessary to go about this situation very carefully and gently. He is using Dickinson to hide his feelings for his mother, and if he does not tread lightly, he may be found out. It can be easily inferred who he does not want to know, namely his father becau... ...laims that â€Å"Hope has feathers/ that reason is a plank/ that life is a loaded gun† (44-46). In essence he seems to be saying that while maybe how he feels is not right, that there is hope, and reason is such a narrow thing, and that life can blow up at anytime, so why bother with pretences. He seems to conclude that the definition between wrong and right can constitute a gray area, and in doing so redeems himself from the idea that lusting after his mother is immoral. While on the surface Collins seems to want Emily Dickinson, with a close reading it becomes clear that he is actually obsessed with his mother. His displacement shows how he at least tries to hide is incestuous desires, while his anal retentiveness shows his wish to be in control. The indications that run throughout the poem reveal Collins’ true feelings, and his inability to hide them.

Aquarius Advertising Agency: Case Study

Aquarius Advertising Agency: Case Study 1)Aquarius’ 5 Contextual Variables: Environment – the business environment for advertising agencies is variable and always undergoing changes. In particular, it is common for these agencies to lose and gain large numbers of clients frequently. In regards to the advertising services Aquarius provides, their employees need to adapt to new industry trends often and no consistent routine exists for serving the various clients they encounter. Goals – Aquarius strives to be a respected agency in the advertising industry.They try to achieve this by being responsive to changes in the industry, flexible with clients, innovative, and efficient. Aquarius’ specific goal it is trying to achieve with structure redesign is to improve cooperation, coordination, and communication among their different departments. Culture – the services Aquarius provides are tied into an industry that revolves around creativity and art. As a r esult, many of the employees strive to be independent and do things in an original way in order to stand out. The personnel are highly knowledgeable towards industry trends and advertising practices.Employees need to be creative and innovative; therefore, they can sometimes be seen as daring or arrogant. Some employees who have a more functional role in the company (i. e. the account executives/manager) feel that the other employees can seem overconfident or egotistical. Size – Aquarius is a medium-sized advertising agency that offers two services. Technology – Technology is always changing and providing new ways for advertising agencies to operate and perform. In terms of performance, traditional forms of advertising such as TV and radio have not been improved by technology for quite some time.However, new Internet technologies like social media are revolutionizing the advertising industry and Aquarius has had to adapt to those changes. In terms of operations, technol ogy has been improving the ways organizations communicate with their clients and how departments relay information throughout the organization. Email is very common these days, however, new information systems and database software are changing the way all organizations of any kind deal with all data. 2 and 3) Matrix structure or not?A matrix structure would not be appropriate in this case because the functional departments under operations deal with each other and the functional departments under marketing deal with each other. The functional departments from operations don’t interact with the functional departments in marketing enough (applies vice versa) to warrant a matrix structure. Also, the functional departments in operations and marketing are too varied from one another to benefit from a matrix structure. The operations departments need to be managed by an operations executive and the same can be said about the marketing departments.The horizontal relationships betwe en operations and marketing need to be vertically controlled for efficiency. However, Aquarius still needs to solve its problem of innovation and flexibility. My restructuring solution would be to add 3 new positions. Aquarius claims its services can be grouped into two categories: one for customized plans and one for complete plans. Therefore, I propose they group together the account executives dealing with clients asking for common services. Also, group together the account executives dealing with more custom and specialized services.These two groups would then report their needs to the other new position called the Accounts/Specialist Liaison. This liaison would act as a permanent integrator between the two account executive groups, the marketing VP, and the operations VP. The two account executive groups relay their resource needs to fulfill customer demands through this liaison. This liaison, knowing the resources and capabilities of the marketing departments and the operation s departments, would then approve or deny the account executive groups’ requests.Although this restructuring plan would be considered to be adding more vertical integration with a single centralized liaison, it still adds flexibility and a divisional structure. The account executives are arranged in a way that one group of executives deal with common services and the other group deals with customized services. As a result, the group dealing with common services will generally have more standardized and consistent requests to the liaison. On the other hand, the group dealing with customized services will have more variable requests.One group would comprise of executives who serve more of a functional role, while the other group would comprise of executives who serve a more creative/innovative role. Either way, everything these two executive groups request, in order to service their respective clients, will have to be approved by the liaison that checks with the two VPs to see if their requests are feasible or reasonable. The liaison also communicates with the Accounts VP often to get a good understanding on special or specific clients and how much they mean to the agency. The liaison relays this information to the two account executive groups.

The Fires Of Jubilee Book Report Essay Example

The Fires Of Jubilee Book Report Essay Example The Fires Of Jubilee Book Report Paper The Fires Of Jubilee Book Report Paper It was written in a way that was very easy to understand which made the book that much better. Dates also made sure to reveal to his readers who the mysterious Nat Turner really was. Dates was also the author of the books With Malice Toward None which won the Christopher Award and Let the Trumpet Sound which also won the Christopher Award and the Robert F. Kennedy Memorial Book Award. In this book, Dates vividly reenacted the events that fueled Gnats mindset, the events that took place during Nat Turners rebellion, and the effects that it had after. Dates began with an extremely thorough biography of Nat Turner who was born on October 2nd, 1 800 in Southampton County, Virginia. As a child, everyone who met Nat knew that he was a special, for he was very intelligent, religious, literate, and was also believed to be a prophet by many of his fellow slaves. Gnats intelligence was praised by his first master, Benjamin Turner, but not by his son, Samuel Turner, who became Ants new owner after Benjamin had passed and he did not appreciate his intelligence as much. It was also during this time that Nat first began slave work at the age of twelve under Samuel Turner. This was also the first time that he recognized that he was a slave even though he had been led to believe by whites and blacks alike that e would be freed one day because he was so smart. This event in Gnats life could have been first time he developed his resentment toward the white man. From that moment on, Nat performed the same bleak routine for many years. This routine 1 included going to slave praise meetings every Sunday where Nat would listen to a different version of Christianity than what the white preachers told. This alternate version criticized slavery and tried to instigate the blacks into resisting it. These praise meetings could have had a great influence with Gnats resentment towards the white man as well Samuel Turner. These praise meetings also influenced Nat to begin his own ministering religious rants within the slave cabins which became very popular among them. When Nat was twenty-one years old, he stated that he, Having soon discovered to be great, I must appear so, and therefore studiously avoiding mixing in society, and wrapped myself in mystery, devoting myself to fasting and prayer. (pig. 27) In 1819, when the United States experienced a depression and Samuel Turner died, Elizabeth, Samuels wife, was forced to sell some of the slaves, as well as Nat Turner. Nat was fortunate enough to be able to stay in Southampton County and he was sold to one Thomas Moore. Gnats new master was an ambitious man who hoped to make it big in his neighborhood. He was not a cruel master but he worked himself and his field hands very hard in an effort to achieve his dream. In the summer of 1825, Nat began to have visions that assured him adjustments Day was approaching. When the slaves heard of his visions, they were astonished, even though they expected to one day hear this news from the prophet. On the other hand, the white people did not pay much attention to Nat because for one, he was a slave, and two, he was not a certified preacher. On May 12, 1828, Nat had the most significant vision of all. He recalled, I heard a loud noise in the heavens and the Spirit instantly appeared to me and said the Serpent was 2 loosened, and Christ had laid down the yoke he had borne for the sins of men, and that I should take it on and fight against the Serpent, for the time was fast approaching when the first should be the last and the last should be the first. (pig. 41) This was the message from God that Nat had searched for. All he had to do now was wait for a sign from God on when to begin. In February, 1831 Nat confided his plan for insurgence in four slaves whom he rusted, Hark, Nelson, Henry, and Sam. On Sunday August, 21 Gnats lieutenants, accompanied by Jack Reese and Will Francis, sat at Cabin Pond and awaited the prophet. When Nat arrived he assured them that they would kill all the white people that night. (pig. 67) Gnats Rebellion began at around am, Monday morning with their first attack to be the Travis house. The insurgents killed all the members of the Travis family, including the Travis baby. After this, Dates recounts all the gruesome slaughters that took place during Gnats Rebellion including Elizabeth Turner, John Barrow, and the only arson that Nat killed throughout the entire insurgence, Margaret Whitehead The following day, Nat rode to the Blunt plantation to attempt to gain more followers but was shocked to find gunshots coming from the home when the arrived. Nat decided to retreat to the forest because most of Gnats men had disappeared or were injured but once there, found the militia waiting for heir The militia viciously attacked the insurgents leaving the remainders of them scattered and three of them dead, including Will Francis. This finally caused the rebellion to subdue. Meanwhile the Southampton community was in a Tate of confusion and panic wondering why had their slaves rebelled and if they were still a threat? Many furious whites decided to take 3 matters into their own hands seek revenge On any black person they saw. There was also a $500 reward for anyone who brought the prophet to the Southampton County Jail, which fueled the manhunt even more. Although many stories stated that Nat had fled the state, he had actually never left Southampton County. On October 3rd, Nat was finally captured by Benjamin Phipps, a farmer who happened to stumble upon Nat. The next day as Nat was being escorted to a Jerusalem Courthouse, he ironically kept his head led high then entire time in front of the large white crowd. In the courthouse, Nat stood before court justices, James Treatment and James W. Parker, who sought to question him. In the interrogation, Nat stated that he was the man in charge of insurrection and omens that God had presented him to see. Although whites did not know how to react to Gnats interrogation many whites agreed that, as perfect a state of fanatical delusion as ever wretched man suffered. (pig. 1 1 9) Thomas Gray, a defender of some of the other insurgents, wanted to interview Nat before his trial date. On Tuesday, November 3rd Gray went to interview Nat for three days and came up with the conclusion that even though he though Nat was engulfed with his religious fantasies he did not think of him as ignorant or a coward. (pig. 12, On November 5th, Nays trial date, Nat was found guilty and on Friday, November 1 1 , Nat was hung. Southern whites desperately wanted to blame Gnats Rebellion the northern abolitionists but in reality, the North had no direct correlation with the insurgence. Southerners more specifically wanted( to link it to William Lloyd Garrisons Liberator and David Walkers Appeal to he Colored Citizens of the World, no evidence exists that slaves ever got a chance to even know about these documents.

Likable and Dependable

Likable and Dependable Are these two tools part of your branding? Arent sure? Then theyre probably not. But why are these two traits so important when youre selling your words and not a public performance? Jane Friedman and Porter Anderson recently established a newsletter on the publishing industry titled THE HOT SHEET (http://hotsheetpub.com/). I was a Beta reader as they worked out the kinks. Its intensely smart, as would be expected from these two industry brains, but in a recent issue they addressed this issue of what readers expect in an author: The scientific finding from Nielsen: Authors, in general, are among the publics fave people in the entertainment world. Only TV and film actors score more highly with fans, which means that authors are rolling in ahead of sports figures and musical artists. Whats more, fans of authors like their authors more than fans of other types of people like their icons - even athletes are not as highly thought of Most of the authors I know fall into one of two categories: 1) They write a lot and promote when they have a new release or an upcoming event; or 2) They promote one book a lot and are slow in putting out new releases. That makes both inconsistent and less reliable, and according to that Nielsen report cited in THE HOT SHEET, makes those writers give the appearance of being less successful, influential, and dependable. So what does that mean for you . . . the burgeoning, struggling writer? It means you write and market each and every day. You appear to always be on the move, always producing, always available to the reader. Its hard, but doing otherwise these days when the competition is steep and the books cheap, will leave you in a lot of writers dust where readers wont be able to find you.

Proponents of the Defamation Act 2013 hailed it as a milestone for Essay

Proponents of the Defamation Act 2013 hailed it as a milestone for freedom of expression. In light of this, critically consider whether and to what extent the Act has the effect that is attributed to it - Essay Example As of October 2013, most High Court judges had thrown out two dozens of cases brought forward by wealthy people or foreigners about claims published mostly by the media. This has curbed the behaviour of people of exploiting England courts. Throwing out most of the cases, Judges have described claimants endeavours as an abuse of law or process, claiming that it they were harming the England and Wales reputation by making their country seem like they do not respect peoples’ freedom of expression. Allowing such case to move on endangers unequal and needless interference with freedom of expression. Judges today are stressing that claimants have to present considerable harm to their repute in England courts in order for the suits to succeed. Otherwise, it would be a waste of time to take your claim to court. This is a significant ruling because it now prevents people for making use of the law when the matter is not that

The financial relives are not the only effective factor for the satisfying job, in the recent time the leave structure, flexibility of work time, the health insurance packages and internal medical supports have become the great issues. The new generation of employees has new expectations from the employees and practically it is the responsibility of the employers to take care of the health of the fellow employees as far as they are working in the same company. This particular paper will focus on the recent scenario of the occupational hazards and with respect to that the safety measures will be discussed intensely. The concept of occupational health safety was evolved in the Europe in the early nineteenth century. The rapid reformation of the occupational health reformation was seen in the Europe and eventually the new trends of the safety measures were shifted to America from the Europe (Taylor, Easter & Hegney 2). The changing in the legislation has helped many poor women and children to stay out of the occupational accidents and occupational hazards. However, the occupational disasters and accidents have a great impact over the local publics too. The laws related to the occupational hazards and standard of safety must be strict enough to have great implications over the present work culture. A great organization has different degrees of satisfactions. According to many motivational

Summary of the article - Assignment Example Few years after 1612, tobacco sale in the London market competed with imported Spanish leaf and commanded steep prices. Virginia discovered tobacco production to be profitable. The tobacco shipment registered a drastic increase between the years 1680 and 1627 despite an Indian attack that killed nearly 400 of Virginia’s colonists (DeFord 1). According to Robert’s history, tobacco culture dominated the region between the southern boundary of Pennsylvania and the northern tidewater area of North Carolina. Seek for a more productive and fertile land steered America’s westward expansion. Human resource became an essential requirement in Maryland and Virginia with increasing hard work in the fields. In 1660, legal slavery appeared for the first time in Maryland and Virginia. Tobacco production continued to rise despite the fluctuating prices. Farmers of Tidewater incurred enormous debts to the British tobacco merchants. After 1750, financial crises abroad forced English merchants to demand payment from the planters. After the revolutionary war, negotiators calculated Virginians to account for millions of pounds of the

The model which Wal-mart uses are "low cost always" is been highly successful in USA's market where people value their hard-work and money. Although this model has been successful in most of the countries it operates in, this model didn't work-out in Japan. Japanese people were not ready to compromise presentation for low-cost and this corporation faced their first hurdle since its incorporation.

The huge disparity in cultures of various nations may tempt wal-mart to change its strategy from implement a global strategy to start using a multi-domestic strategy. Multi-domestic firms usually develop separate strategies for their different subsidiaries in different parts of the world. One such c ompany is Uni-Lever, which uses a multi-domestic strategy (Daft, 1997). Their advertising policies and products are usually varied from one country to another. Similarly, McDonald in the recent years has also used multidomestic strategies. It developed a new product McKofta for Middle-Eastern market just to suit their taste buds. Pizza Hut has also introduced Chicken Tikka Pizza for Pakistani and Indian markets.(Cluster Flock, 2009) Thus it can be established from the above discussion that those businesses which have used multi-domestic strategies are more successful than those who follow a one rigid policy for their businesses in all countries. Even companies like Dell are also going more towards customization and this shows how important being flexible is in current business situation and recessionary times. So, it is imperative for Wal-mart to change their strategy immediately and should try to make strategies on the basis of different culture of different countries.

Ideal Sampling Frame in Marketing - Assignment Example The scale is mostly used by marketers when previous information about a particular product is not available. If the marketer simply base his decision of manufacturing a product on the basis of the results that state that more consumer has selected the probably will buy and definitely will buy the product, then he may end up making a mistake because usually very low number of consumers who state that definitely will buy might not actually buy the product. Â  The ideal sampling frame is a term used to denote a sample frame in which the entire population is accessible and no one is missing, this does not take place in the real world. In the absence of such frame, an alternate way called representative sampling can be utilized to determining the same sample frame may be used with aid of characteristics of the sample that need to be tested. Â  Probability sampling is referred to the selection of samples that are selected on a random basis and not in accordance with the convenience of the researcher. Non-probability sampling arises when samples are selected in a random manner in accordance with convenience. Example: Conducting a survey of the school you study and selecting school students as sample. Â

Effects of Divorce on Children Essay Example for Free

Effects of Divorce on Children Essay Although divorce is now allowed by law in some countries, it is still unhealthy for a family especially in the presence of a child. Due to the fact that they are still young, the children often do not understand why some couples need to separate and they respond in a variety of ways that parents should understand and deal with. When the divorce is settled, the children might wonder why their father or their mother is no longer around and this might be quite hard to explain to a young mind. This produces short and long term effects on the children and even sometimes causes teenagers to rebel against their parents causing more problems than there already is. Another issue regarding children and divorce is who will have custody of the children and alimony. Usually, the mother gets custody over the children while the father still provides financial support. Depending on the situation, the custody is being granted to the father. One problem about divorce is that couples think that the matter is only between them; failing to consider what effects it would have on their children. Little do they know that the changes that will occur once the divorce takes effect will have many negative effects on children. In a case to case basis, children might feel different because of the many changes that will take place once the divorce becomes effective such as changes in schedules and daily routines as well loss of contact with members of extended family (Parker). Children may also develop a fear that losing one parent will eventually lead to the lost of the other. The loss of attachment of a child to a parent may also lead to the loss of other secure relationships such as friends, siblings, neighbors and even pets. Children also, more often than not, are attached to their surroundings and divorce sometimes mean moving out or migrating which could prove unhealthy for the wellbeing of a child. A parent also has a tendency to create a dis-attachment between the child and the other parent which could prove to be a major predicament in the psychological health of the child (Parker). Many children tend to think that they are somehow the reason why their parents want to get divorced. Children often remember rough times that they had with their parents such as arguments, poor grades, getting into trouble, vices, etc. They start to think that the conflict came from them and they start to blame themselves. If this is the case, the parents should make clear that they are not responsible for the conflict and that both of the parents still love them. Explaining custody arrangements would also prove better to prepare the child and for a better understanding (Clandos). In some cases children try to bring their parents back together by either â€Å"acting out† in negative ways or trying â€Å"so good† so that his/her parents would think twice and reconsider about pursuing the divorce (Parker). As a reaction to a divorce, children especially teenagers show aggressive and defiant behavior. A problem here is that parents usually think that this is the normal behavior of the children instead of a reaction to problem. Parents should be keen observers and must be able to identify if the behavior is still normal. In such cases, children also show depression and parents must watch out for this kind of reactions (Parker). In one study, it has been proven that children have adapted to their parents divorce and have emerged as successful individuals. According to Constance Ahrons, the author of Were Still Family: What Grown Children Have to Say About Their Parents Divorce, although they are now adults, children who belonged in families that divorced emerged â€Å"stronger and wiser† having coped with â€Å"difficult times and experienced stressful family changes†. The research indicated that 79 percent feel that their parents decision to have divorce proved to be a good one. On the other hand, according to David Blankenhorn, founder of the Institute for American Values, â€Å"a good divorce is not nearly as important as having less divorce. No matter how good your divorce is, it is still a very painful experience for your child (Peterson). Many children who have grown up may have coped with the effects of divorce but still, a good number of children were affected and were not able to cope with it. It has been proven that children from divorced families are usually victims of abuse and exhibit more health, behavioral and emotional problems compared to children from intact families. Data also indicate that children from divorced families have more likely been associated with drugs, crime and even suicide (Fagan). According to a survey conducted by the Department of Health and Human Services, National Center for Health Statistics, fatherless children show a much greater risk of committing suicide while another study indicated that three out of four teenage suicide cases are from families where a parent is absent. Moreover, another study by Kalter and Rembar indicated from a sample of 144 children and adolescents that 63 percent showed subjective psychological problems such as anxiety, sadness, moodiness, phobias and depression while 56 percent had poor grades. Another 43 percent showed aggressive behavior towards their parents (Fatherless Homes Statistics). Children from divorced couples have been noted to perform poorly in academic subjects such as reading, spelling and math. They have also been identified to have higher drop-out rates and more often repeat a grade. It was also indicated that these children have a less likelihood of graduating from college. It was also noted that families that have gone through a divorce have experienced a 50 percent drop in their income levels resulting in poverty. Divorce also resulted in less religious worship which is associated with many positive outcomes such as better health, longer marriages and improved family life (Fagan). Divorce also affects the sexual behavior of children. Children from divorced families start to accept premarital sex and divorce. The National Longitudinal Survey of Youth indicated that â€Å"African–American girls are 42 percent less likely to have sexual intercourse before age 18 if their biological father is present at home. For Hispanic–American girls, the stepfather’s presence increases the likelihood of sexual intercourse before age 18 by 72 percent† (Fagan). Robert Sampson, a professor of sociology at the University of Chicago, discovered that divorce rate is connected to the robbery rate in 171 cities in the United States that have a population of at least 100,000. Lower rate of divorce meant higher social control which in turn also results in lower crime rate. There is also a close line relating child abuse and crime rates. Higher divorce rates result in higher rates of child abuse but instead of curbing child abuse, remarriage only adds to it. Having a stepfather would most likely increase child abuse and data indicate that serious cases of abuse is much higher for stepchildren compared to children from whole families (Fagan). Likewise, a study by Kalter indicates that teenage and adult females that have been exposed to parental divorce resulted in lower self-esteem, heightened sexual activity, delinquent behavior and are unable to maintain a lasting heterosexual relationship. It was also stated that girls who grew without interaction from a father missed out on a key element. â€Å"The continuous sense of being valued and loved as a female seems an especially key element in the development of the conviction that one is indeed femininely lovable. Without this regular source of nourishment, a girls sense of being valued as a female does not seem to thrive† (Fatherless Homes Statistics). Children may suffer traumatic experiences in cases of divorce but steps can be taken to reduce these kinds of effects that divorce has on children. These steps are the following: â€Å"(1) be honest for the potential of emotional trauma on each of your kids; (2) allow your children to communicate openly; (3) offer your children choices, whenever possible, to increase their sense of power over their lives; (4) find support for yourself and your children; and (5) provide continuity† (Clandos). It is, likewise advised not to expose the children to any marital conflict. Talking about the spouses negative behavior should also be avoided while developing amicable relationship with the spouse is advisable for the sake of the children. Taking care of ones self will also help children adjust to the changes caused by the divorce. Moreover, discussing the separation with the children would also be helpful but one must always be mindful because what one says might affect the outlook of the child in a negative way (Clandos). Some changes in behavior may be observed from children that have been affected by the separation. Some children who are most of the time jolly and playful may become moody and may lose self-esteem. Sadness and moodiness may become excessive at times. Children also sometimes develop a fear of â€Å"clinginess† and may show anger outbursts (Clandos). Teen marriage account for a good percentage of divorce cases. Early marriages have been considered more unstable because of different factors such as the inability to support a family because of the absence of a good paying job having not finished college. It is estimated that one half of teen marriages with women ranging from 18 to 19 years of age result in divorce within 15 years time although the rate of divorce for women over 20 is also particularly high at around 33 percent. In cases of out-of -wedlock pregnancies, marrying before giving birth will increase paternal support because the male partner would have better access to the child and may provide better financial support even if there is a high risk that the marriage will result in an divorce (Seiler, 7). According to data from the National Center for Health Statistics, over time, the rate of divorce per 100 marriages have increased from three in 1870 to 30 in 1945 and 51 in 1998 (Fagan). Half of the marriages in the US end in divorce and from this data, one may state that people now no longer consider marriage as a strong binding force for a couple. Marriage now no longer provides a perception that it is permanent. Marriage is also no longer considered as a life-changing decision because of the availability of divorce. Dating games such as The Bachelor which sometimes end in marriage is proof enough that people no longer take marriage seriously. A divorce is caused by many factors such as common misunderstandings, financial difficulties, adultery, vices, and other irreconcilable differences. Many couples experience financial difficulties and this is one cause of divorce but prior to what most believe, financial problems are not the top cause of divorce. It only ranks fourth or fifth next to other factors that produce higher divorce rates, namely, â€Å"incompatibility, lack of emotional support, abuse and sexual problems†. According to Jan Andersen, associate professor at California State University in Sacramento, only 5 percent of divorce cases are caused by a couples financial difficulties (Weston). Other usual causes of divorce aside from financial problems are â€Å"lack of commitment to the marriage, lack of communication between spouses, infidelity, abandonment, alcohol addiction, substance abuse, physical abuse, sexual abuse, emotional abuse, inability to manage or resolve conflict, personality differences or ‘irreconcilable differences’,differences in personal and career goals, different expectations about household tasks,different expectations about having or rearing children, interference from parents or in-laws, lack of maturity, intellectual incompatibility, sexual incompatibility, insistence of sticking to traditional roles and not allowing room for personal growth, falling out of love, religious conversion or religious beliefs, cultural and lifestyle differences, inability to deal with each other’s petty idiosyncrasies, mental instability or mental illness, criminal behavior and incarceration for crime† (Panse). Even if many countries legal ly accept divorce, there are still some countries that do not approve of divorce and most of these countries are against divorce because of religious beliefs. In biblical texts, adultery is often mentioned but nothing is clearly mentioned about divorce. Even theology scholars and pastors do not share the same views regarding biblical teachings about divorce. Christian scholars have different positions regarding the controversial issue. They argue that â€Å"(1) divorce is never permitted under any circumstances; (2) divorce is permissible under certain, specified circumstances; and (3) divorce is permissible under many circumstances† (House). The first argument supports that â€Å"marriage is lifelong and permanent† and divorce is against Gods standards and Christians are strictly prohibited from having divorce. Those who support the second argument that divorce is permissible under specific circumstances believe that divorce is not prohibited by biblical texts. They believe that one spouse commiting adultery means that a divorce can be allowed. Desertion is also being considered as a valid reason for divorce in this argument. On the other hand, the third view argues that divorce is allowed not just for conditions of adultery and desertion but for many other conditions as well (House). Generally speaking, divorce has many adverse effects on children. It affects their behavior, emotional and psychological health. Although some research studies indicate that children have been able to overcome the behavioral, emotional and psychological effects caused by divorce and were able to break out as successful individuals, many children still suffer from the harmful effects of divorce. As discussed, children from divorced families have a higher tendency to commit suicide, are more likely to commit crime and premarital sex as well as having poorer performance in academics. To sum it up, divorce does not provide any good effects on children and because of the many negative effects, it would be better if couples do not resort to divorce so as not to disregard the well-being of their children. It would be better off if couples just settle their differences for the sake of the children. It is also recommended that the government take steps to at least be able to lessen the cases of divorce if not eliminate it. On the other hand, the church should re-orient people the importance of marriage and deciding who to marry as simple as it has become today. The Church must make the people know that marriage is a life-changing decision. The status of marriage, particularly in the United States which is one of the countries with the highest divorce rates, is not strong. Works Cited Parker, Wayne.

Greek Roman Athletic

Greek Roman Athletic Greek and Roman sports Introduction Ancient Greek and Roman civilization have made many enduring contributions to western civilization. Such as politics, sports, and trade are present in western society because of Greece and Rome. The Ancient Greeks and Romans have engaged a everlastingly nebulous place in our psyche, and have hence assumed a powerful place in our fantasies about many things. Running the gamut from wrestling to boomerang, Sports and Games of the Ancients spans the world to bring us collection of athletic and spirited pastimes, rituals, and contests. In Ancient Greek and Romans Sports, athletic contested very hard and it was a public display that was a trait of the religious and social life of ancient Greece and Rome (Osborne 15). The ancient athletes were untainted in mind and body and they trained and participate for no other reason than the passion for physical exercise, fair competition and to honor their gods. In this article I will to discuss the Greek and Roman attitudes toward sports. Attitudes of the two Societies The Greek society was unique in way because it was the first to put man at the center of the universe. Unlike the creature deities of the Egyptians and Mesopotamians, the gods of the Greeks are human in form. Man was there source of inspiration and thus loved they he would be competitive in all fields specially sports. The Roman society did not had the time or inclination to turn to softer, lazier, and altogether more debauched things such as sitting around and talking or writing books. Nevertheless, the Romans, unlike the Greeks, were illustrious by practicality and common sense, not by a love of abstract thought. The Roman societies imagination has too often been regarded as, at worst, deficient and derivative, and, at best, pragmatic rather than sophistic (Osborne 74). The similarity between Greek and Roman thought has I think by and large been over-simplified in modern accounts, and has not often been considered to be an interesting subject. Still both had similar paths of creation, conquest, and destruction. How brutal were Greek sports The ancient competition, physically, was poles apart from our modern games. There were far fewer events and only free Greek speaking men (and sometimes boys) were allowed to compete because of severity and brutality. There was no team competition, and the emphasized on individual achievement through public competition was related to the Greek ideal of excellence, called Arete. In Greece the games served at first as a constituent in various spiritual observances: Some were held in admiration of the gods, some as offerings of thanksgiving. Others, in later times, were held in honor of living people. The Greek games where brutal but with their attendant processions, feasts, and music, played an important role in developing the approval of physical beauty that is typical of Greek art and literature. The four main cycles of games were the Olympic Games, the Pythian Games, the Isthmian Games, and the Nemean Games (Kyle 48). Was Roman sporting even more brutal then the Greek sports The Roman games, like those of the Greeks, were partially religious in nature. However, corrupt politicians used the games to win the errands of the populace and vied with one another in the lavishness and profligacy of the games, which were held on the flimsiest of pretexts and eventually lost their original religious meaning and purpose. Certainly warfare familiarized Romans with violence, and violent spectacles escalated with, and symbolized, the territorial expansion of the empire and the blood sports acted as a surrogate for war. Public spectacles were of various kinds. They included a gladiatorial combat, stage-plays in every quarter of Rome performed in every language, chariot races in the Circus, athletic competitions, and a mock naval battle. Without a doubt, the Greek games depended for their entertainment value primarily on rivalry among athletes; while the Roman games were often describe by the staging of battles fought to the death and involved large numbers of human beings and also beasts (Kyle 184). The Roman sporting was crueler because in Greece the people were often participants, whereas in Rome they were mere spectators, and only professional athletes, slaves, and prisoners usually took part. Conclusion The Greek and Roman cultures truly transformed the art of civilization. We can clearly see the love for sports in Greek and the Romans. It was through Justinians code, Roman law influenced civil law codes throughout much of Western Europe (Kyle 26). We learn that the ancient Greeks and Romans shaped their own idea about the meaning of life. The Roman games were radically different from the Greek games in several respects. But still it shows the mindset of the people of that time. Without a doubt the modern Americans would find much of that sports awfully violent; particularly the hundreds of gladiator contests and animal fights, with their many public deaths of both people and wild animals. We surely learn that some upper-class Romans were dismayed at the brutality of the games but defended them as a means of directing popular anger away from the elite. The useful lessons we learn I think is of bravery and courage in the face of death. Works Cited Osborne, R. Studies in Ancient Greek and Roman Society. New York: Cambridge University Press, 2004.

Culutual Anthropology :: essays papers

Culutual Anthropology As an amateur anthropologist, I was to participate in my observation, which I did to the best of my ability. Choosing my topic was the most difficult for me. Coming to America there are so many options that I could choose to research. So what was I to do? Well, being in the state of Kentucky, Lexington at that, I decided to research a sporting event in which Americans call basketball. As soon as I stepped of the big metal bird, I saw a picture of a wild cat holding a round orange ball. I remember thinking, "I could never hunt these animals, they are too smart, they are nothing similar to the ones in the Outback of Australia. So I stopped the person that rode next to me on the metal bird, "What is that animal doing with that ball?" He remarked, "We are in Lexington, home of the Kentucky Wildcats." With that he walked away. How could Kentucky be considered the home of the wildcat? We have many in the Outback. So, I continued down the nest where the birds drink and rest. Then it finall y hit me, the name of the basketball team were the Wildcats. I was well on my way to find these "Kentucky Wildcats." I arrived where they house the wildcats that play ball. The name of the cage was Rupp Arena. Apparently, I was not the only one interested in watching these trained animals play the sport of basketball. The price to watch these animals were extremely expensive; thirty dollars in American currency which would translate into 300 of my own currency. Once inside the cage I found that it was not at all what I thought it to be. There was an enormous amount of people present. In my observation this event is the biggest that people in this culture attend. In this cage you could smell a variety of things. Some smells were all too familiar from home; the urine smell as you walked into the place where people went to relieve themselves reminded me of the "Hole." They had many different foods that smelled nothing like anything that I have ever smelled before. They had a brown thing that was twisted into a weird design; they had something that was in the form of a triangle that looked like a piece of bread with cheese on top and round meat.

Living in a country that is seen to be melting pot of many cultures and heritages, you are bound to encounter someone of another culture but that doesn’t mean we suppress their ability to represent who they are because of their lack of knowledge pertaining to the primary language used in this country. Immigrants use language to preserve their culture heritage and identity in a foreign land but fear of judgment, suppression and linguistic terrorism affect their ability to fit in and be who they are not only by Americans but also by their own people. Linguistic terrorism is a term used by Anzaldua herself to express her strong emotions on the suppression of her language by others. This term is used to describe an action of suppression by a majority group to a minority group because of their values, norms and even language. This occurs because one usually feels dominant and superior over the other. Anzaldua states in her essay that â€Å"Our language has been used against us by the dominant culture; we use our language differences against each other.† (136) Living in a diverse cultural country such as the United States, many immigrants feel the need to learn the appropriate English in order to communicate and fit in with society. Many aren’t able to completely emerge themselves into the American way of doing things without sacrificing a part of themselves through their cultural heritage and identity. Majority of them feel the need to learn English in order to get a job. Even then they are suppressed because they speak with very simple English with heavy accents. Once these immigrants start to feel comfortable with their English, they are often pushed off by their native tongue because of embarrassment and disrespect to their own language. There are times when groups that have tried so hard to fit in with the Americans are looked down upon by their own culture and society. Anzaldua says, â€Å"‘Pocho, cultural traitor, you’re speaking the oppressor’s language by speaking English, you’re ruining the Spanish language,’ I have been accused by various Latinos and Latinas† (133). This portrays how her own people have looked down upon her because the English she speaks now is evident through her Spanish, shaming the language as a whole in their eyes. Such things cause people to feel discouraged and fear being judged by their own culture. This fear of judgment causes people to have multiple consciences. Sociologists use the term double conscience, a term that coined by W.E.B. Du Bois, to explain such phenomena. It is a way of awareness of who you are and a very different awareness of what other people see you as in contrast to that. The way you act at home would be different in terms of your values, social norms and language. Once you leave your home and enter another society, those values, norms and even language change to those that are commonly believed and used in that newer society. Anzaldua notes that â€Å"My ‘home’ tongues are the languages I speak with my sister and brother, with my friends†¦ last five listed†¦ From school, the media and job situations†¦ standard and working class English. From Mamagrande Locha and from reading†¦standard Spanish and standard Mexican Spanish† (134). A double conscience or a multiple on can be used to explain Anzaldua’s reason for using different languages in different parts and areas of her daily life. She talks about how she picked up different languages from different places because it was important for her to fit in and communicate with them, changing her conscience along the way . Gloria Anzaldua is a strong activist when it comes to the connection between language and identity. In her essay â€Å"How to Tame a Wild Tongue† she outlines her strong emotional arguments about the ability for one to conform to a society by disposing their own language or identity. Your identity is determined by language, the language you speak is a part of your culture, and your culture is what defines a person because of their beliefs, norms and values. Even though there will always be Linguistic Terrorism and suppression, it is important to remember that your language is what makes you who you are and changing from one language to another is something you must do but that doesn’t mean you let that change your true language or your true identity.

MERITS AND DEMERITS INTRODUCTION: Bluetooth was originally conceived to replace the rat’s nest of cables typical in any PC setup today and this remains a compelling home application.However, as the Bluetooth evolved it became clear that it would also enable a totally new networking paradigm, Personal Area Networks (PANs)! With PAN technology a user will be able to organize a collection of personal electronic products (their PDA, cell phone, laptop, desktop, MP3 player, etc. ) to automatically work together. For instance the contact manager and calendar in the P DA, laptop, and desktop could all automatically synchronize whenever they are within range of each other). Over time PANs will revolutionize the user experience of consumer electronics.Finally, Bluetooth’s dynamic nature will also revolutionize connectivity to the rest of the world. Bluetooth will automatically discover devices and services nearby so available servers, internet access, printers etc. will automatically become visible to a Bluetooth device wherever it is. HISTORY: Bluetooth is an open specification for short range wireless voice and data communications that was originally developed for cable replacement in personal area networking to operate all over the world.By enabling standardized wireless communication between any electrical devices, Bluetooth has created the notion of a personal Area Network (PAN), a kind of close range wireless network that looks set to revolutionize the way people interact with the information technology landscape around them. In 1994 t he initial study for development of this technology started at Ericsson, Sweden. In 1998, Ericsson, Nokia, IBM, Toshiba, and Intel formed a Special Interest Group (SIG) to expand the concept and develop a standard under IEEE 802. 15 WPAN (Wireless Personal Area Network ).In 1999, the first specification was released and accepted as the IEEE 802. 15 WPAN standard for 1Mbps networks. The Bluetooth SIG considers three basic scenarios: †¢ The first basic scenario is the Cable Replacement ie. the wire replacement to connect a PC or laptop to its keyboard, mouse, microphone, and notepad. It avoids the multiple short range wiring surroundings of today’s personal computing devices. †¢ The second scenario is ad hoc networking of several different users at very short range in an area such as a conference room. The third scenario is to use Bluetooth as an AP to the wide area voice and data services provided by the cellular networks, wired connections or satellite links. Why th e name Bluetooth? The story of origin of name Bluetooth is interesting. †Bnluetooth† was the nickname of Harald Blaatand, 10th century Viking who united Denmark and Norway. When Bluetooth specification was introduced to public, a stone carving, erected from Harald Blaatand’s capital city Jelling was also presented. This strange carving was interpreted as Bluetooth connecting a cellular phone and a wireless notepad in his hands.The picture was used to symbolize the vision in using Bluetooth to connect personal computing and communication devices. What is BLUETOOTH? [pic] Figure1: Bluetooth system blocks The Bluetooth system consists of a radio unit, a link control unit, and a support unit for link management and host terminal interface functions (see Figure 1). The Host Controller Interface (HCI) provides the means for a host device to access Bluetooth hardware capabilities. For example, a laptop computer could be the host device and a PC card inserted in the PC is the Bluetooth device.All commands from the host to the Bluetooth module and events from the module to the host go through the HCI interface. The protocol stack is above the radio and baseband hardware, partly residing in the Bluetooth unit and partly in the host device. A Bluetooth solution can also be implemented as a one-processor architecture (embedded solution) where the application resides together with the Bluetooth protocols in the same hardware. In that case, the HCI is not needed. This is a feasible implementation for simple devices such as accessories or micro servers.Requirements of Bluetooth technology: †¢ If Bluetooth technology is to replace cables, it can not be much more expensive than a cable or nobody will buy it. †¢ Because Bluetooth technology is designed for mobile devices it must be able to run on batteries. So it must be very low power and should run on low voltages. †¢ It must also be lightweight and small enough not to intrude on the design o f compact mobile devices such as cellular phones, handsets etc. †¢ It must be as reliable as the cable it replaces and also it must be resilient. †¢ Bluetooth devices operate at 2. GHz in globally available, license free ISM band, which obey a basic set of power and spectral emission and interference specifications. THUS Bluetooth has to be very robust, as there are many existing users and polluters of this shared spectrum. Thus Bluetooth aims to be widely available, inexpensive, convenient, easy to use, reliable, small and low power. Specifications related with Bluetooth: |PARAMETER |VALUES | |Frequency Range |2. – 2. 4835 GHz | |Bandwidth of each channel |1MHz | |Data rate |1 Mbps | |Frequency hopping rate |1600 hops per seconds | |Range of operation |10-100 meters | Bluetooth system operates in 2. GHz Industrial Scientific Medicine (ISM) band. The operating band is divided into 1MHz spaced channels each signaling data at 1 Mbps so as to obtain maximum available channel bandwidth with chosen modulation scheme of GFSK (Gaussian Frequency Shift Keying). Using GFSK, a binary 1 give rise to a positive frequency deviation from the nominal carrier frequency while binary 0 gives rise to a negative frequency deviation. After each packet both devices retune their radio to a different frequency, effectively hopping from radio channel from radio channel.In this way Bluetooth devices use the whole of available ISM band and if transmission is compromised by interference on one channel, the retransmission will always be on a different channel. Each Bluetooth time slot lasts 625 microseconds giving rise to frequency hopping rate of 1600 hops per seconds. Generally devices hop once per packet. .For long data transmission, particular users may occupy multiple time slots using the same transmission frequency thus slowing instantaneous hopping rate to below 1600 hops/ sec. BLUETOOTH NETWORKS: PICCONETS AND SCATTERNET:The Bluetooth network is called a piconet . In the simplest case it means that two devices are connected (see Figure 2a). The device that initiates the connection is called a master and the other devices are called slaves. The majority of Bluetooth applications will be point-to-point applications. Bluetooth connections are typically ad hoc connections, which means that the network will be established just for the current task and then dismantled after the data transfer has been completed. A master can have simultaneous connections (point-to-multipoint) to up to seven slaves (see Figure2b).Then, however, the data rate is limited. One device can also be connected in two or more piconets. The set-up is called scatternet (see Figure 2c). A device can, however, only be a master to one piconet at a time. Support for hold, park, or sniff mode is needed for a device to be part of the scatternet. In these modes a device does not actively participate in a piconet, leaving time for other activities such as participating in another pic onet, for example. The master/slave roles are not necessarily fixed and can also be changed during the connection if, for example, the master does not have enough esources to manage the piconet. Master/slave switch is also needed in the scatternet. Master/slave switch support is not mandatory. Most of current Bluetooth implementations support piconets only. Point-to-multipoint support depends on the implementation Figure 2. Bluetooth piconet and scatternet scenarios: a) Point-to-point connection between two devices b) Point-to-multipoint connection between a master and three slaves c) Scatternet that consists of three piconets Modes of operation: In connection state, the Bluetooth unit can be in several modes of operation.Sniff, hold, and park modes are used to save power or to free the capacity of a piconet: Active mode: In the active mode, the Bluetooth unit actively participates on the channel. Sniff mode: In the sniff mode, the duty cycle of the slave’s listen activity ca n be reduced. This means that the master can only start transmission in specified time slots. Hold mode: While in connection state, the ACL link to a slave can be put in a hold (possible SCO links are still supported). In hold mode, the slave can do other things, such as scanning, paging, inquiring, or attending another piconet.Park mode: If a slave does not need to participate in the piconet but still wants to remain synchronized to the channel (to participate in the piconet again later), it can enter the park mode. It gives up its active member address. Park mode is useful if there are more than seven devices that occasionally need to participate in the same piconet. The parked slave wakes up regularly to listen to the channel in order to re-synchronize and to check for broadcast messages sent by the master.. FREQUENCY HOPPING :Bluetooth technology uses a frequency hopping technique, which means that every packet is transmitted on a different frequency. In most countries, 79 chann els can be used. With a fast hop rate (1600 hops per second), good interference protection is achieved. Another benefit is a short packet length. If some other device is jamming the transmission of a packet, the packet is resent in another frequency determined by the frequency scheme of the master. This scenario is depicted in Figure 3 where packets of device 1 (colored packets) and device 2 (banded packets) are trying to use the same frequency.Note that this case only refers to situations where there are two or more simultaneous active piconets or a non-Bluetooth device using the same frequency in range. The error correction algorithms are used to correct the fault caused by jammed transmissions Figure 4. Three-slot and five-slot long packets reduce overhead compared to one-slot packets. 220  µs switching time after the packet is needed for changing the frequency. Subsequent time slots are used for transmitting and receiving. The nominal slot length is 625 (s.A packet nominally c overs a single slot, but can be extended to cover three or five slots, as depicted in Figure 4. In multi-slot packets the frequency remains the same until the entire packet is sent. When using a multi-slot packet, the data rate is higher because the header and a 220 (s long switching time after the packet are needed only once in each packet. On the other hand, the robustness is reduced: in a crowded environment the long packets will more probably be lost HOW DOES BLUETOOTH WORKS? Bluetooth devices have 4 basic States.They can be a Master (in control of a Piconet — represented by a large blue circle above), an Active Slave (connected and actively monitoring/participating on a Piconet — medium orange circles), a Passive Slave (still logically part of a Piconet but in a low power, occasionally monitoring but still synchronized, inactive, state — medium gray circles), and Standby (not connected to a Piconet, occasionally monitoring for inquiries from other devices, but not synchronized with any other devices — small white circles). IN IDEAL STATE Bluetooth devices initially know only about themselves and in this state they will be in Standby mode.Standby is a passive mode where a Bluetooth device listens on an occasional basis performing what are called Inquiry and/or Page Scans for 10 milliseconds out of every 1. 28 seconds to see if any other Bluetooth devices are looking to communicate. Passive behavior is inherent to half of Bluetooth’s states and is a key mechanism to achieving very low power. In Standby mode the Bluetooth device’s occasional attention reduces power consumption by over 98%. While all of the Bluetooth devices in the same mode it is important to note that they are NOT synchronized or coordinated in any way.Thus they are all listening at different times and on different frequencies. [pic] Enquiry and page procedures lead to connections ENQUIRY: Inquiry is how a Bluetooth device learns about other devices that are within its range. In the illustration above Node A executes a Page Function on the BT Inquiry ID and receives replies from other devices. Through these replies device A learns the explicit identity of these other devices (i. e. their unique Bluetooth device ID). During the Inquiry process device A continuously broadcasts the Page command using the reserved Inquiry ID which identifies it as as a Page Inquiry.These broadcasts are spread across a standard pattern of 32 Standby radio frequencies which all devices in Standby mode monitor on an occasional basis. Over a duration of some seconds it is certain that every Standby device within range will have received the Inquiry Page even though they are not synchronized in any way. By convention these nodes will respond with a standard FHS packet that provides their unique BT ID and their clock offset. With these parameters the Inquiring node can effect low latency synchronized connections.Node H (the dotted circle above) illustra tes how a Bluetooth device can be programmed to remain anonymous (Undiscoverable in BT jargon). This is a user controlled feature that suspends Inquiry Scanning, and thus device A’s Inquiry Procedure cannot discover Device B It is important to note that device H will continue to support Page Scanning however, and thus a user’s other personal devices (i. e. PAN) can penetrate this barrier by Paging directly to its unique Bluetooth ID. This is information that PAN devices can be configured to know and remember thus enabling private collaboration even when devices are undiscoverable.PAGING: In its general form the Page command establishes a formal device to device link between a Master (the originator) and a Slave. Master/Slave connections in Bluetooth are referred to as a Piconet. To create the piconet device A broadcasts the Page command with the explicit device ID of the target Slave (B in the illustration above) which was learned earlier through an Inquiry Procedure. Further, this connection can be very low latency if the Inquiry data is recent (and thus synchronization can be accurate), but the process will simply take longer if this is not the case.All Bluetooth devices except B will ignore this command as it is not addressed to them. When the device B replies, device A will send it an FHS packet back and assign it an Active Member Address in the Piconet. As an Active Slave device B will begin continuously monitoring for further commands from device A in synchronization with device A’s hopping pattern and clock offset. Further, standard Piconet activity continuously updates the clock offset data keeping the synchronization extremely accurate. Thus the Master and Slave states are not low power but exhibit very low transaction latencies. EXPANDING A PICCONET:Through successive Page commands a Bluetooth Master can attach up to 7 Active Slaves. 7 is a hard limit as only 3 bits are allocated in Bluetooth for the Active Member Address (AMA) w ith 000 reserved for the Master and the remaining addresses allocated to Slaves. Practically, 7 is more than sufficient given Bluetooth’s modest performance and dynamic configurability. Again, all Active Slaves to A continuously monitor for further commands addressed to them in synchronization with device A’s hopping pattern. PARKING: Parking is a mechanism that allows a Bluetooth Master to connect to an additional 256 devices. 56 is a hard limit as 8 bits are allocated in Bluetooth for the Parked Member Address (PMA). To Park a device the Bluetooth Master issues a Park command to an Active Slave and assigns it a PMA. This Slave then enters the Parked mode and surrenders its AMA. As a Parked Slave the device will revert to a passive mode and only monitor for commands on an occasional basis. The difference between Standby and Parked however is that the Slave will remain synchronized to the Master’s hopping pattern and regularly update its clock offset. Thus this device can be reconnected at any time with a minimum latency.BLUETOOTH PROTOCOLS: Protocols are needed to implement different profiles and usage models. Every profile uses at least part of the protocol stack. In order to achieve interoperability between two Bluetooth devices, they both must have the same vertical profile of the protocol stack. Bluetooth Core Protocols Baseband and Link Control together enable a physical RF link between Bluetooth units forming a piconet. This layer is responsible for synchronizing the transmission-hopping frequency and clocks ofdifferent Bluetooth devices [Whitepaper1, p. ]. Audio is routed directly to and from Baseband. Any two Bluetooth devices supporting audio can send and receive audio data between each other just by opening an audio link . Link Manager Protocol (LMP) is responsible for link set-up (authentication and encryption, control, and negotiation of baseband packets) between Bluetooth devices and for power modes and connection states of a Bluetooth unit. Logical Link Control and Adaptation Protocol (L2CAP) takes care of multiplexing, reassembly, and segmentation of packets.Service Discovery Protocol (SDP) is needed when requesting device information, services, and the characteristics of other devices. Devices have to support the same service in order to establish a connection with each other. Cable Replacement Protocol RFCOMM emulates RS-232 signals and can thus be used in applications that were formerly implemented with a serial cable (e. g. , a connection between a laptop computer and a mobile phone). Telephony Protocol Binary (TCS-BIN) defines the call control signaling for the establishment of speech and data call between Bluetooth devices.AT commands provide means for controlling a mobile phone or a modem. Adopted Protocols OBEX (Object Exchange) is adopted from IrDA. It is a session protocol that provides means for simple and spontaneous object and data transfer. It is independent of the transport mechanism an d transport Application Programming Interface (API). TCP/UDP/IP is defined to operate in Bluetooth units allowing them to communicate with other units connected, for instance, to the Internet. The TCP/IP/PPP protocol configuration is used for all Internet Bridge usage scenarios in Bluetooth 1. and for OBEX in future versions. The UDP/IP/PPP configuration is available as transport for WAP. PPP in the Bluetooth technology is designed to run over RFCOMM to accomplish point-to-point connections. PPP is a packet-oriented protocol and must therefore use its serial mechanisms to convert the packet data stream into a serial data stream. The Wireless Application Protocol (WAP) stack can reside on top of RFCOMM (based on LAN Access Profile) or on top of L2CAP (based on PAN Profile). The latter reduces overhead and is likely to become the preferred solution for WAP over Bluetooth.Wireless Application Environment (WAE) hosts the WAP browser environment. Dial up networking (DUN) profile protocol stack: DUN profile is inside the Serial Port Profile and therefore partly reuses the capabilities of the Serial Port Profile. For the DUN Profile, there are two device configurations (roles): †¢ Gateway (GW) is the device that provides access to the public network (typically mobile phones and modems) †¢ Data terminal (DT) is the device that uses the dial-up services of the gateway (typically PCs) The DUN Profile needs a two-piece protocol stack and an SDP branch.PPP over RFCOMM is needed for transferring payload data. AT commands are delivered over RFCOMM to control the modem (mobile phone). The application on top of the stack is either a driver application on a PC (data terminal) or the modem emulation on a phone (gateway). Bluetooth security: secret key All Bluetooth devices (master and slave) share a secret key in a particular system. This key is used during the authentication and encryption process. This key is not transmitted over the channel but is rather in-built b y the manufacturer. AUTHENTICATIONAuthentication ensures the identity of Bluetooth devices. Authorization is a process of deciding if a device is allowed to have access to a specific service. User interaction may be required unless the remote device has been marked as â€Å"trusted. † Usually the user an set authorization on/off to every remote device separately. Authorization always requires authentication. Authentication in Bluetooth is performed by an encryption engine which uses the SAFER+ algo. This algorithm requires the following: †¢ Number to be encrypted or decrypted †¢ master address †¢ Master clock secret key shared by master and slave. A random number is generated by the encryption engine using various keys. This random number is encrypted by the master using the secret key. This number is also sent to the slave. The encrypted reply of the slave is compared with the master encrypted data. If it is a match then the slave is authentic. BONDING AND PAI RING Pairing is a procedure that authenticates two devices based on a common passkey, thereby creating a trusted relationship between those devices. An arbitrary but identical passkey must be entered on both devices.As long as both devices are paired, the pairing procedure is not required when connecting those devices again (the existing link key is used for authentication). Devices without any input method, like headsets, have fixed passkeys. When two devices are linked with a common link the connection is called as bonding. There are two types of bonding: †¢ Dedicated bonding: Used to create and exchange a link key between two devices. †¢ General bonding: Data over the link is available for higher layers. ENCRYPTION Encryption protects communication against eavesdropping.For example, it ensures that nobody can listen to what a laptop transmits to a phone. Encryption demands the following: †¢ Negotiating encryption mode †¢ Negotiating key sizes-The key size coul d vary from 8 to 128 bits †¢ Starting encryption †¢ Stopping encryption SECURITY LEVELS A trusted device has been previously authenticated, a link key is stored, and the device is marked as â€Å"trusted† in the security database of a device. The device can access Bluetooth services without user acceptance. An untrusted device has been previously authenticated, a link key is stored, but the device is not marked as â€Å"trusted. Access to services requires acceptance of the user. An unknown device means that there is no security information on this device. This is also an untrusted device. Security Level of Services Authorization required: Access is only granted automatically to trusted devices or untrusted devices after an authorization procedure (‘Do you accept connection from remote device? ’). Authentication is always required. Authentication required: The remote device must be authenticated before connecting to the application. Encryption required : The link must be changed to encrypted before accessing the service.It is also possible that a service does not require any of these mechanisms. On the other hand, the application (service) might have its own user authentication mechanisms (a PIN code, for example). APPLICATIONS: 1. Bluetooth in the home will ultimately eliminate most every cable related to consumer electronics (except power). Your PC, scanner, and printer will simply need to be within 10 meters of each other in order to work. Your PDA, digital camera, and MP3 player will no longer need a docking station to transfer files or get the latest tunes (the exception will be to recharge, that power thing again).And, your home stereo and other equipment will join the party too. On the telephone front your cell phone will synchronize its address book with your PC and function as a handset to your cordless phone in the house (answering incoming calls to your home number and calling out on the cheaper land line too). Finally, even though its only 720Kbps, Bluetooth is still pretty fine for broadband internet access since DSL and cable modems are typically throttled to about 384K anyway. Bluetooth access points could well be as ubiquitous as 56K modems in 2 or 3 years. . On the road much of your Bluetooth PAN goes with you. Even when your laptop is in your briefcase and your cell phone is in your pocket they will be able to collaborate to access e-mail. And, next generation cell phones featuring Bluetooth and General Packet Radio (GPR) technology will function as a wireless modems with internet access at 100Kbps+. With such performance it is likely web based e-business will flourish and these devices will become the most prevalent Bluetooth access points.This may well be the Killer App that ensures Bluetooth’s widespread adoption and success. When you are literally on the road your car will join your PAN too. Here your cell phone may operate in a hands free mode using the car audio system and an i n-dash microphone even while comfortably in your pocket. Or you may use a wireless Bluetooth headset instead. And, your MP3 player will likely play music in 8 speaker surround sound, rip music right off of an FM broadcast, or record your phone calls for later review. And all without wires!!!Fixed land line access points (supporting up to 720Kbps) such as a pay phone in the airport terminal or lounge, or the desk phone in your hotel, will provide true broadband access in these strategic locations. Also look for the pay phone to evolve to compete for your cell phone calls too with its low cost land lines. In the world of deregulation and open competition future smart phones may even put your calls out for bid and channel the traffic over the carrier offering the lowest cost! 3.
