CRR-2 - Essay Example This approach, according to (Davis and McKay 1996, p. 100) first of all recounts the oppositions views, and also to help construct the writers own position. After having registered his stance, Howard delves right into the point of the argument he likes to defend by reiterating Deegans concern "what did my son die?" (Howard 2002, p.11). In fact at this point Howard continues with his pathos by registering contingent emotions through the description of the Islamic fanatics who bombed Bali using terms like "despise", "liberal", "open life of western nations" and "violent murder" to appropriate orientation between himself and the audience (Cockcroft & Cockcroft 1992, p.40; Hughes 1990, p. 33). By addressing Deegans concerns one by one Howard logically defends and establishes his ethos (the concept personality and stance as introduced by Aristotle). As a reader since we do not have any preconceive idea as to his character or emotions, these lines establish his personality as sympathetic, logical and as concerned as any Australian citizen (his audience). The essence of Howards argument lies in his statement that Australia is publicly and closely associated with the US since September 11, 2001 because of security reasons. However, in the next five to six paragraphs, Howard digresses from his stance. While he manages to use facts to establish logos, the "process of judgement" (Cockcroft and Cockcroft 1992, p. 10), he does not effectively make a case for his argument. According to Bakhtin (Andrews 1992, p.8), argument principles involve internal dialogic quality of discourse" which means both the sender and receiver must understand the elements of logic in an argument. In these paragraphs Howard digress from his logic, which loses the appeal he established at the beginning of the letter, thereby reduces his credibility. The loss of credibility is also because of Howards inability to find the correct analogy to defend his

Cyclermate Consultancy report - Essay Example This report will try to establish whether it is possible for Cyclermate Company to clear off its debts and attain financial stability in the near future with the increasingly loss of profitability. Background information Cyclermate Company has been enjoying unprecedented growth in the manufacture of cycles for quite some time. However, the last few years have seen the profits of this company sink sharply resulting from declined sales. The company was started in 1988 by two friends, Lewis Llewellyn and Dai Armstrong who had been in this business of making cycles for more than 20 years.The two friends brought their wealth of experience together and they decided to start a cycle manufacturing business going by the name Cyclermate. Within just a span of slightly more than two years, the firm had expanded to an extent that the two friends decided to acquire premises from where they were conducting their business. With increased demand for their product, the staff also increased considerab ly but they still insisted on keeping the staff at a skeletal minimum to cut costs. Everything was done manually or through the use of old or effective machinery. Automation was discouraged as they couldn’t justify buying the machines that were to be used in bending of the bars to manufacture these cycles. The issue of quality with these cycles arose when a cycle had an accident and blamed it on the fault of a braking system. Sales have declined and with a few creditors, Linda Llewellyn, who is Lewi’s wife and she demands that her share of the business be given to her and along term loaner, Geraint Williams, who relies on the payments from this loan to take care of his ailing wife. There is much financial pressure on the business and if measures are not taken into place, financial strain could cause the business to close down (Campello, Graham, & Harvey, 2010; Bancel, & Mittoo,2011). To this regard, the chairman Dai Armstrong and Gwyneth Morgan the secretary were taske d with the prerogative of arranging for a meeting with the bank to negotiate the possibility of an overdraft. The bank had already stipulated that this request would be highly unlikely to be considered unless the company provides proof that there would be increased trading to turn around the declining profits. To be able to know for sure whether the company can be capable of turning around and consolidate itself on the financial front in the short run, a full overview and assessment of the country will be done in this report. A SWOT analysis will be conducted to identify the areas of strengths, weaknesses, opportunities as well as threats that face this company. The issue of quality in production will also be illuminated upon. Measures that the company is undertaking to ensure it reverses these negative profits will also be looked into among other relevant issues pertaining to this case. Assumptions made To be able to provide a comprehensive and granular analysis of the company in f orm of its financial position and other aspects such as production techniques as well as marketing strategies and administration strategies, a number of assumptions will have to be made here. These assumptions are discussed in the following paragraphs. The main assumption is that both the company management and the bank acknowledge that the company had been performing well in the past but the

Canada Statutory Law Analysis

Canada Statutory Law Analysis David Kafka Californias statutory law establishes that employment, having no specified term, may be terminated at will by either the employer or employee. Cal. Lab. Code ÂÂ § 2922 (2017). This presumption is subject to contrary evidence, such as an implied or expressed agreement that an employment relationship will continue indefinitely. The issue in this case is whether Reynaldo Perez had an implied contract of employment with Malloys Department Store that could be terminated only for cause. If an employer has created an implied or expressed contract for permanent employment, that employee may be terminable only for good cause. When determining if an implied agreement exists, the court will look at a number of factors. These include: personnel policies or practices of the employer, employees longevity of service, assurances by the employer for continued employment, and practices of the industry. Formal handbooks and manuals outlining employment terms are also given consideration. An implied covenant of good faith protects the parties right to receive the benefit of their agreement, but does not necessarily create any other duty outside of the contract. Pugh was found to have had an implied agreement with Sees Candies based on his duration of employment, lack of criticism for work, assurances given, and his employers acknowledged policies. Pugh v. Sees Candies, Inc., 116 Cal. App. 3d 311 (1981). Pugh was frequently told that if he did a good job, his future with the company was secure. There was also a policy where administrative staff would only be fired for good cause. Pugh was not given a reason for his termination, nor was it based on good cause. The court found that an implied contract existed, and Pugh was wrongfully terminated. Id. At will provisions in company manuals are significant in determining the policies of an employer. Parol evidence is admissible to explain, supplement, or even contradict the terms on an unintegrated agreement Guz v. Bechtel Natl, Inc., 8 P.3d 1089 (Cal. 2000). When an employer has policies in formal handbooks, it create[s] a clear and uniform alternative to haphazard practices, understanding, and arrangements within the company. Id. Guz was told by a Bechtel official that the company avoids arbitrary firings. However, the court found that the company did not waive its right to discharge its employees at will based on this statement. Id. The court places great credence in what is included in formal handbooks when determining if employment is at will. An official cannot waive those policies simply by making his or her own arrangements. Guz received no promises that he would be retained except for good cause. His long employment, raises, promotions, and good reviews were not sufficient enough to prove that an implied contract existed where he was no longer an at will employee. The court found that the implied covenant of good faith did not protect Guz from termination. Id. Perez was employed at Malloys for a total of 20 years, consistently received good evaluations, had salary increases, and on one occasion was given assurance his job was safe if he kept performing at a certain level. Perez was told early in his employment by the president of Malloys that his job would always be safe, and that the company doesnt just fire people. The length and success of his employment might also benefit his argument for an implied contract. The companys application form contained ambiguous language which could be interpreted as a contract for continued employment. It stated that Malloys hires and retains hard-working people. However, both the application form and employee manual reiterate that employment is at will. The application stated our employment relationship will end whenever we determine that it should. The employee manual had similar language, stating that an employee could be fired at any time, for any reason. It is likely that the employee manual and job application form will be given great consideration. Malloys clear policy of employment at will was outlined in these documents and contradict any promise that was made to Perez early in his career. As in Guz v. Bechtel Natl, Inc., 8 P.3d 1089 (Cal. 2000), an employee handbook is admissible in court to explain or contradict terms of an unintegrated agreement. In Perezs case, the handbook will likely contradict the presidents statement that his job would always be safe. Perez agreed with the company president that he was fine with his reassignment. He continued working in this position for an entire year. There was never a clear agreement that Perez would only be fired for just cause, and there was no indication that this was Malloys company policy. Therefore, it is unlikely that the court will find that Perez had an implied contract of employment that could be terminated only for cause.

Fear in Wordsworths My heart leaps up when I behold, We Are Seven, Tin

Fear in Wordsworth's My heart leaps up when I behold, We Are Seven, Tintern Abbey, and Resolution and Independence Fear in Wordsworth's "My heart leaps up when I behold", "We Are Seven", "Tintern Abbey", and "Resolution and Independence" Romantic poetry conjures in the mind of many people images of sweet, pastoral landscapes populated by picturesque citizens who live in quaint houses in rustic villages, with sheep grazing on green-swathed hills, while a young swain plights his troth to his fair young maiden, who reclines demurely amidst the clover and smiles sunnily. William Wordsworth is perhaps the archetypal Romantic poet; his most famous poem, "I wandered lonely as a cloud", would seem on first reading to support the traditional, one could say stereotypical, image of a Romantic poet. Even his name, Words-worth, reinforces that image. And yet, upon looking more closely and carefully at his works, it becomes clear that the emotions which motivate his creativity are not solely a love of nature and pastorality. Let us consider Wordsworth's "My heart leaps up when I behold". The poem can be interpreted on a very simple level as a typical Romantic poem: there is the glorying in and of nature that most people immediately think of when Romantic poetry is mentioned. The speaker is thrilled when he sees a rainbow, he was thrilled in his youth when he saw a rainbow, and when he is old he will continue to be thrilled by seeing a rainbow; if he cannot be thrilled, he would rather be dead. The speaker's life has a kind of continuity, of stability, through the process of memory. The reader can wipe away a tear and mumble "Isn't that nice?", and switch on Three's Company; this interpretation affirms our sense of what poets should fee... ...rom finding "In that decrepit Man so firm a mind" (line 145), finding, however temporarily, a source of courage against his fears (lines 146-147): 'God,' said I, 'be my help and stay secure; I'll think of the Leech-gatherer on the lonely moor.'

Media Literacy Essay

Literacy gives us minorities the ability to read and write. Today, we get most our information through an interwoven system of media technologies. The ability to read many types of media has become an essential skill in the 21st Century. Media literacy is the ability to access, analyze, evaluate, and create media. I came up with this topic because Media literate youth and adults all over America to better understand the complex messages we receive from television, radio, Internet, newspapers, magazines, books, billboards, video games, music, and all other forms of media.Media can present content that seems and is more or less real, however, it is our duty as the viewers to be able to distinguish, and differentiate between â€Å"reflections of reality, and constructions of reality†. The prime targets of the media are young people because they so unwittingly believe everything the media tells them, from â€Å"how to talk, how to dress, and how to relate to others†. Media literacy skills are included in the educational standards of every state in language arts, social studies, health, science, and other subjects. My potential strength is giving my audience various types of important effects of global media literacy such as education ,health related issues, drugs, alcohol, tobacco, body image, obesity, sex distractions , lack of knowledge and all types of sports that does and does not effects our globalization. I researched and found out many researchers have discovered that media literacy is an effective and engaging way to apply critical thinking skills to a wide range of issues. My main Importance I want my audience to know about media literacy, according to Edward Donnerstein who is a major research interests in mass-media violence, as well as mass media policy. He has published over 240 scientific articles in these general areas and serves on the editorial boards of a number of academic journals in both psychology and communication. Donnerstein States that in his book † Media literacy skills can help youth and adults by developing critical thinking skills, Understanding how media messages shape our culture and society ,recognize, bias, spin ,misinformation, lies and also evaluate media messages based on our own experiences, skills, beliefs, and values. † I learned from Donnerstein that this project with media literacy fit within the existing globalization because media literacy is a delicate issue that has some good and bad effects on everyone in today’s society. For example, Communication has become a major tool to connect if we want to travel to Africa or learn  about Australia information is at our fingertips .We can text someone instantly and get a response back from Russia immediately. We can call someone over Skype in India and talk for free on our computer for as long as we want. Not to mention Facebook and Twitter which have become the most popular social networking tools on the worl d. My study according to Cole VT 2006, an article on television and obesity talks about how the media has strong influence over public thought because of the universal demand of the media, because of the accessibility of media it becomes more influential to those who watch it and the viewers who believe the ideas and stereotypes portrayed through the media; nevertheless, they become the individuals who become influenced by the media. The media demonstrates the ability to create and influence those who watch television; however, one particular group that the media has targeted is children. Television and internet has allowed for the expansion of knowledge to expand globally, but also has the ability to corrupt the mind of the youth. Cole gives us audience a quote stating†The expansion of knowledge is spreading and so is the waist size of the American youth†. It has been established that television, internet and social medial allows for children to become educated through these conventional outlets; however children should be limited to a minimal amount of television because there is correlation between excessive television, internet and an increase in BMI, which has been linked towards the causes of obesity in children. Obesity effect children’s who consume a significant am out of television such as erratic behavior, less active in physical activity, deprivation of sleep, mood swings, Increase in laziness, and increase in weight again which consents of obesity. According to Kong JP, in 2010 his Journal of Society for development in new net environment in B&H. â€Å"children who watch up to three hours of television on average, watching up to at least 40,000 TV commercial per year and developing a favorite television show or program that retains their attention. Based on the fact these impacts can lead to a significant decline in health and overall performance of children. If these bad habits remain continuance this could lead to an unhealthy life and unhealthy habits, which can ultimately be fatal†. However, we parents need to set a good example, because they are role models for their child, and the behavior that children have is usually a replica of the parents. Some parents allow for children to be consumed by television, while they  gallivant in their own activities instead of spending time with their child. By allowing a child to consistently watch television instead of being active in a physical activity can result in the child becoming lazy. It is important to encourage your child to do other activities outside of watching television, so it’s good not to invest all your time on television and find an outside source for entertainment. For instance, if a child asks to play with their mom or dad and the mom tell their child I do not have time, go watch television. Ultimately, the child will begin to rely on the television as there daily activity. It is imperative as a parent that you find quality time to spend with your child and that quality time should be spent awa y from the television. My Methodology of data I collected throughout a quantitative and qualitative research study is that I gain from Elsevier Health Sciences that it is imperative to understand that childhood obesity is at all-time high, and as the years increase so does the sizes of the American children. If children are going to is watching a significant amount of television and internet daily there should be other alternatives and activities provided in place of the television. For instance, for every amount of television or technology being used will result in the same amount of time spent actively engaging in an activity that does not require you to sit in front of the television or , or iPad, Xbox 360 and etc. Also, it is recommended that a maximum of two hours should be spent watching these technologies. According to the American Academy of Pediatrics (2001), it is recommended in order to help reduce the amount of television and internet being consumed is to not watch television or use technologies while eating meals, remove all televisions from blatant/obvious places in the houses, such as the living room. There should be no television located in the children’s room because children will stay up all night with their eyes fixated at the television or technologies. Also, it’s good to implement days without television and to plan family activities that allow to children engage actively. By limiting the amount of hours spent on television and internet can help reduce the risk of children becoming obese and allow for them to find other activities that can be beneficial to their growth and allow for them to live a healthy life. Children’s greatest exposure to violence comes from television. TV shows, movies edited for television, and video games expose young children to a level of violence unimaginable just a  few years ago. According to Salmon J, Campbell KJ, Crawford DA states in their Journal of Society for development in new net environment in B&H that majority of teenagers and children today know the underlying themes of the media, and know that it is all scripted even the violence, however, the matter of fact is that teenagers can relate so much to the themes in the media that they slowly begin to believe it. Once they get introduced to the characters, they gradually start to consider them real and starts to partipate in bad behavior Cambell states in his journal that â€Å"our community in today’s society face many obstacles with our youth and the media that is destroying the foundation of family’s and juvenile delinquency. For example, social learning theory, strain theory and control theory, just to name a few, are typically postulated for being directly related our media juvenile delinquency. In dealing with all of these effects and how they play a role with delinquency the question still remains as to whether or not higher crime rates in juveniles are significantly increased when media plays a big factor†. The media has the ability to influence social constructed ideas and creating stratification amongst minorities and ethnic groups allowing for the uses of the television and social media outlets to become addicting. As a result of this addiction it enable individuals such as children to become or remain fixated on these primitive idea of life. And because of this strong addiction towards being entertained it is important to stay tuned to the media and the most up to date gossip or the newest television show. However, According to Tracy Marie Scull who is The National Association for Media Literacy Education’s Journal of Media Literacy Education talks about sex in her article she states,†During adolescence, young people are exposed to information about sex from a myriad of sources including mass media Adolescents frequently cite mass media as a primary source of information about sex (Sutton et al. 2002). Somewhat surprisingly, the media far outrank parents or schools as a source of information about birth control for 15-19-year-olds .In fact, young teens (ages 13-15) rank entertainment media as their top source for information about sexuality and sexual health. Unfortunately, while the media are communicating a plethora of sexual messages, many of those messages would not be considered accurate or healthy. For example, while the amount of sexual content on TV has nearly doubled since 1997 very few teen television shows mention any of the  responsibilities or risks (e.g., using contraception, pregnancy, STIs) associated with sex and almost none of the shows with sexual content include precaution, prevention, or negative outcomes as the primary theme†.

Socrates’ death

To begin with, we need to introduce Socrates. Socrates was and still regarded as one of the most influential philosophers. Socrates throughout his life showed a deep understanding of the human life, as well as an understanding of the world. He is considered one of the most important ethical philosophers of all time. Nothing much is known about his personal life, but his works were well preserved which revealed a lot about him as a great man. Socrates was sentenced to death and was put into prison because he disobeyed the roman god, and claimed to be led by a mysterious power. He was accused with offences against public morality. After his sentence was released a lot of his friends and jury expected him to refuse the sentence, but for their surprise, he did not say anything and he accepted the sentence readily. Many of his friends urged him to escape the prison, but he refused saying that the state should be obeyed. He stayed in prison for 30 days because at the time of his sentence romans had a sacred time in which they did not kill anybody. During that time, many of his friends came to him and urged him to leave the prison, but he refused. One of the most important visits by his friends was Crito’s visit. Crito visited him the last day before his sentence, and they argued about whether Socrates should escape or not. In his argument, Crito used a teleological approach. He presented Socrates with the consequences of him staying in jail. On the other hand, Socrates replied to him using deontological approach, defending his point of view using valid reasons. First Crito presented Socrates with the argument that people will say that Socrates did not choose to stay in prison; it must be his friends that did not talk to him. By this, he is saying if you don’t escape people will talk badly about your friends. By this argument, Crito shows a large interest in public opinion, and a large care about his reputation. This represents a teleological approach, because he is stating facts and consequences of Socrates staying in prison. When Socrates heard this, he immediately refuted this argument. He told Crito that he should not care about the majority’s opinion. Socrates gave the example of a trainer and a student. He says that when the student does something, everybody around him will talk about the thing, but he doesn’t listen to anybody but the trainer. Then he tells Crito that he should do the same thing because â€Å"the general public† is not qualified to judge anybody. It is the responsibility of a qualified person to give judgment for actions taken by others. This argument represents a deontological approach, because he is talking about a purpose. He is not listing facts and consequences; he is just saying that all matters of justice and injustice should be handled that way because it is the right way. According to Socrates justice and truth work together. He gave an argument saying that the state is the one that bough him to life, and is the one who could end his life. He made a comparison between the state and parents. He said that the state in a sense is like a parent, who always wants the best for his son. This is a deontological approach because he did not say anything about a consequence he just listed his belief and his point of view on the subject. To add, Socrates mentioned another point, which is that by disobeying the state you are breaking a commitment and by breaking the commitment you are doing wrong. This also is a deontological approach of the issue because he is stating a point of view without mentioning any facts or evidence about it. He is just pointing out a personal point of view. He is basing his argument on his perception of right and wrong, without any reference to factual evidence. He said that by disobeying the state and going out of prison without an official charge he would be unfair and unjust to the people of Athens. He says that by escaping, he breaks the law and the law is found for everybody and is fair with everybody, so if he breaks it this justice will break down. This is another deontological approach because he is supporting his point of view using his own perceptions of right and wrong. He does not backup his argument with consequences or related factual evidence. In addition to the deontological approach, Socrates used the teleological approach in addressing some of the issues with him escaping prison. In his argument with Crito about leaving the prison because of his kids, Crito said that if he stays in the prison his children will be orphaned and will have nobody to take care of them and educate them. He used the teleological approach here because he mentioned a consequence of him staying in the prison. Socrates replied to that by saying that by escaping, he would break the law. By breaking the law Socrates would be labeled as an outlaw. Being an outlaw would not allow him to raise his children, because he will be running away from the government the whole time. Not having time for his children will let strangers raise them. While if he stays in prison and dies the state will take care of his children. This shows a teleological approach because Socrates is mentioning a consequence of him running out of prison. He says that if he escapes, he would not be able to live life the same way he was used to living it. In my opinion, Socrates’ argument is better and more concrete because he didn’t just apply the argument to this particular situation. He expanded the analogy to involve every situation that involves a case like his. His analogies could be expanded to any situation involving justice and injustice. In addition, Socrates’ arguments represent real moral values. While in Crito’s arguments, we could see that he is only concerned about himself and his reputation. In addition, they could be only applied to this situation not any other situation. His arguments do not have any real ethical or moral values because he is concerned only about himself. To sum up Socrates’ arguments care about the well-being of every human being, while Crito’s only care about the well-being of himself

Bluetooth to Bluetooth Essays

Bluetooth to Bluetooth Essays Bluetooth to Bluetooth Essay Bluetooth to Bluetooth Essay Bluejacking is the sending of unsolicited messages over Bluetooth to Bluetooth-enabled devices such as mobile phones, PDAs or laptop computers, sending a vCard which typically contains a message in the name field (i. e. , for bluedating or bluechat) to another Bluetooth-enabled device via the OBEX protocol. Bluetooth has a very limited range, usually around 10 metres (32. ft) on mobile phones, but laptops can reach up to 100 metres (328 ft) with powerful (Class 1) transmitters. Bluejacking is the sending of unsolicited messages over Bluetooth to Bluetooth-enabled devices such as mobile phones, PDAs or laptop computers, sending a vCard which typically contains a message in the name field (i. e. for bluedating or bluechat) to another Bluetooth enabled device via the OBEX protocol. Bluetooth has a very limited range; usually around 10 meters on mobile phones, but laptops can reach up to 100 meters with powerful transmitters.Bluejacking allows phone users to send business cards anonymously using Bluetooth wireless technology. Bluejacking does not involve the removal or alteration of any data from the device. Bluejackers often look for the receiving phone to ping or the user to react. In order to carry out a bluejacking, the sending and receiving devices must be within 10 meters of one another. Phone owners who receive bluejack messages should refuse to add the contacts to their address book. Devices that are set in non-discoverable mode are not susceptible to bluejacking.Mobile phones have been adopted as an everyday technology, and they are ubiquitous in social situations as users carry them around as they move through different physical locations throughout the day. As a communicative device, the mobile phone has been gradually taken up in ways that move beyond merely providing a channel for mediated conversation. One such appropriation is bluejacking, the practice of sending short, unsolicited messages via vCard functionality to other Bluetooth-enabled phones.To choose the recipients of bluejacks, senders complete a scan using their mobile phones to search for the available Bluetooth-enabled devices in the immediate area. A bluejacker picks one of the available devices, composes a message within a body of the phone’s contact interface, sends the message to the recipient, and remains in the vicinity to observe any reactions expressed by the recipient. The messages tend to be anonymous since the recipient has no idea who has sent the bluejack, and the recipient has no information about the bluejacker, except for the name and model of the bluejacker’s mobile phone.Because of Bluetooth’s short-range networking capabilities, bluejacking can only occur between actors who are within 10 meters of each other, which makes this activity highly location-dependent. Contrary to what the name suggests, the bluejack recipient’s phone is not hijacked; that is, the phone is at no time under the control of the bluejacker. We conceptualize bluejacking as a violation of possessional territory. Inspired by Goffman, we propose that the mobile phone is a possessional territory as a result of the intimacy and continued contact between mobile phone users and their phones.A possessional territory, in our usage, is an object that engenders attachment and defense by those who perceive possession and can be referred to as a personal effec t. Possessional territories function egocentrically; that is, they move around with their owners who maintain and exert regulatory control, such as the definition of settings. Since we characterize the mobile phone as a possessional territory, we adapt the category of violation, defined as a temporary incursion where gaining control is not necessarily the goal as a likely and appropriate category of infringement in this context.We also propose that bluejackers are attempting to personalize their experience of public space by engaging in the violation of others’ possessional territories through the act of illicit and anonymous messaging. Visitors to public spaces can engage in habitual behaviors at a specific location, such as picking a favorite parking spot that one can return to on each successive visit, to gain a sense of familiarity to locations that are frequently re-visited.These physical environments then hold enough significance to inspire defense among those who inhabit them and defensive behaviors, which can range from defining a personal space within a conversation or while using a tabletop work-surface. Typically, an inhabitant of a public place tends to personalize a location if he or she feels that the social conventions of a space allow one the license to mark a territory. Bluejackers, however, ignore the conflict between the control exerted by the bluejacker and the lack of defensive measures that can be taken by the recipient when his or her possessional territory is violated.To gain a further understanding of why bluejackers would engage in a practice that disrupts the social conventions of public space, we ask the following research questions: 1. What are the characteristics of the public spaces in which bluejacking occurs? 2. What are the alternative social conventions that might arise from the practice of bluejacking? 3. What implications does this appropriation have for the design of mobile social systems? Origin This bluejack phenomen on started after a Malaysian IT consultant named Ajack posted a comment on a mobile phone forum.Ajack told IT Web that he used his Ericsson cellphone in a bank to send a message to someone with a Nokia 7650. Becoming bored while standing in a bank queue, Ajack did a Bluetooth discovery to see if there was another Bluetooth device around. Discovering a Nokia 7650 in the vicinity, he created a new contact and filled in the first name with Buy Ericsson! ’ and sent a business card to the Nokia phone. A guy a few feet away from me suddenly had his 7650 beep. He took out his 7650 and started looking at his phone. I couldn’t contain myself and left the bank, he says.Ajack then posted the story on a mobile Web site and other people started trying it out. I gave it the name bluejacking (taken from the words Bluetooth and hijacking) and it has just taken off from there. He says bluejacking is common in Malaysia and is happening everywhere there are lots of Bluetooth devices. Bl uejacking has become popular among young people wanting to play practical jokes. A 13-year-old named Ellie from Surrey in the UK has started a dedicated bluejacking site called bluejackq. The site explains what bluejacking is and lso has forums where people can share their bluejacking experiences. BLUEJACKING TECHNOLOGY As we know that bluejacking is the sending of unsolicited messages over Bluetooth to Bluetooth-enabled devices such as mobile phones, PDAs or laptop computers, sending a vCard which typically contains a message in the name field (i. e. for bluedating or bluechat) to another Bluetooth enabled device via the OBEX protocol. So bluejacking is based on Bluetooth technology which is explained bellow. Bluetooth technology Bluetooth Technology was developed to solve the simple problem of eliminating the connector cable.The idea is to replace the cables that are needed to accompany portable devices carried by many mobile travelers with a low-cost, secure, robust RF link. Orig inally Bluetooth marketed to small handheld devices such as cell phones and laptops. As the Bluetooth standard emerged successfully into society, the world demanded more. It is reported on Lets Go Digital in an article written by Ilse Jurrien that three new Bluetooth products are qualified every day and 10 million Bluetooth units are shipped per week. Bluetooth is so efficient, effective, and secure that even the IEEE approved the 802. 5. 1 Standard for Wireless Person Area Networks based on the Bluetooth specification. What is Bluetooth? Bluetooth is defined as a wireless technology that provides short-range communications intended to replace the cables connecting portable and/or fixed devices while maintaining high levels of security. There are three key features of Bluetooth; robustness, low power, and low cost. The Bluetooth standard provides a uniform structure enabling a wide variety of devices to seamlessly, and wirelessly, connect and communication with each other.Bluetooth devices connect and communicate via RF link through short-range piconets. Bluetooth devices have the ability to connect with up to seven devices per piconet. Each of these devices can also be simultaneously connected to other piconets. The piconet itself is established dynamically and automatically as Bluetooth enables devices enter and leave the range in which its radio operates. The major pro of Bluetooth is the ability to be full duplex and handle both data and voice transmission simultaneously.The differentiation of Bluetooth from other wireless standards such as Wi-fi is that the Bluetooth standard gives both link layer and application layer definitions which support data and voice applications. Bluetooth comes in two core versions; Version 2. 0 + Enhanced Data Rate and Version 1. 2. The primary differences being Bluetooth 2. 0 has a data rate of 3 Mega byte per second whereas Version 1. 2 has only a 1 Mega byte per second data rate. Both are equipped with extended Synchronous Connections (eSCO), which improves voice quality of audio links by allowing retransmissions of corrupted packets.Bluetooth technology operates in the unlicensed industrial, scientific and medical (ISM) band at 2. 4 to 2. 485 GHz, using a spread spectrum, frequency hopping, full-duplex signal at a nominal rate of 1600 hops/sec. Bluetooth is modulated using adaptive frequency hopping (AFH). This modulation has the capability to reduce interference between wireless technologies sharing the ISM band. It does this by having the ability to detect other devices using the ISM band and use only frequencies that are free. The signal itself hops between ranges of 79 frequencies at 1 Megahertz intervals to minimize interference.The devices themselves are categorized into range ability. There are three classes of devices each covering a select range. Class 1 devices are mostly used in industrial cases and have a range of 100 to 300 meters. These devices take more power than the standard devices you and I are accustomed to in our daily routine and therefore are a bit more expensive. Class 2 devices are most commonly found in mobile devices and the most commonly used. Items such as cell phones and printers are Class 2 devices and have a range of 10 to 30 feet and use only 2. milli-Watts of power. Finally, Class 3 devices have the shortest range of up to 1 meter and include devices such as keyboards and a computer mouse. Class three devices therefore require the least amount of power and are in general the lease expensive. Maximum Permitted Power (mW) | Maximum Permitted Power (dBm) | Range (approximate) | Class 1 | 100 mW | 20 dBm | ~100 meters | Class 2 | 2. 5 mW | 4 dBm | ~10 meters | Class 3 | 1 mW | 0 dBm | ~1 meter | 2. 1. 1 Bluetooth Piconets Let’s say you have a typical modern living room with typical modern stuff inside.There’s an entertainment system with a stereo, a DVD player, a satellite TV receiver and a television; there’s also a cordless t elephone and a personal computer. Each of these systems uses Bluetooth, and each forms its own piconet to talk between the main unit and peripheral. The cordless telephone has one Bluetooth transmitter in the base and another in the handset. The manufacturer has programmed each unit with an address that falls into a range of addresses it has established for a particular type of device. When the base is first turned on, it sends radio signals asking for a response from any units with an address in a particular range.Since the handset has an address in the range, it responds, and a tiny network is formed. Now, even if one of these devices should receive a signal from another system, it will ignore it since it’s not from within the network. The computer and entertainment system go through similar routines, establishing networks among addresses in ranges established by manufacturers. Once the networks are established, the systems begin talking among themselves. Each piconet hops randomly through the available frequencies, so all of the piconets are completely separated from one another.Now the living room has three separate networks established, each one made up of devices that know the address of transmitters it should listen to and the address of receivers it should talk to. Since each network is changing the frequency of its operation thousands of times a second, it’s unlikely that any two networks will be on the same frequency at the same time. If it turns out that they are, then the resulting confusion will only cover a tiny fraction of a second, and software designed to correct for such errors weeds out the confusing information and gets on with the network’s business. 2. . 2 The Bluetooth Architecture The Bluetooth architecture is divided into two specifications: the core and the profile specifications. The core specification discusses how the technology works while the profile specification focuses on how to build interoperating device s using the core technologies. The RF Layer The Bluetooth air interface is based on a nominal antenna power of 1mW (0dBm) with extensions for operating at up to 100 mW (20dBm) worldwide. The nominal link range is 10 centimeters to 10 meters, but can be extended to more than 100 meters by increasing the transmit power to 100 mW.The Bluetooth Baseband The basic radio is a hybrid spread spectrum radio that operates in a frequency hopping manner in the ISM band. As stated earlier, the band is divided into 79 one Megahertz channels that the radio randomly hops through while transmitting and receiving data. A piconet is formed when one Bluetooth radio connects to another Bluetooth radio. Both radios then hope together throughout the 79 channels. The Bluetooth radio system supports a large number of piconets by providing each piconet with its own set of random hoping patterns.The Bluetooth frame consists of a transmit packet followed by a receive packet. Each packet can be composed of mult iple slots (1, 3, or 5) of 625 us. Below is a single slot frame. Multi-slot frames allow higher data rates because of the elimination of the turn-around time between packets and the reduction in header overhead. The method which Bluetooth radios connect to each other in a piconet is fairly simple. IT is called a master/slave design. The master radio can be connected up to seven slave radios at any given time.Any Bluetooth radio can become a master or a slave radio. At the time of formation the piconet configuration is determined. Usually, the connecting radio will become the master, although, most devices have a master/slave swap function that allows the roles to be reversed. In order for the piconet to be established by a Bluetooth Radio, the radio must have two parameters available, that is, the hopping pattern of the radio it is to be connected to and the phase within that pattern. All Bluetooth radios have a Global ID which is unique to the system.The master radio shares its Glo bal ID with other radios. The other radios that receive the Global ID become slaves and provide all other radios with the correct hopping pattern. IT is the master who provides the clock offset with the slaves in the piconet, providing the offset into the hopping pattern. Usually, radios not connected to the piconet are in stand-by mode. While in stand-by mode, radios are listen for other radios to find them, which is called Inquiring, and are listening for a request to from a piconet, which is called Paging.In the event a radio issues an Inquire command, a listening radio will respond with an FHS packet that includes the devices Global ID and clock offset to give the inquiring radio at list of available Bluetooth radios within the local range. A Bluetooth radio will page another radio with its Global ID to form a piconet. The radio that was paged will respond with its Global ID and the master radio will pass the radio that was paged and FHS packet. The radio that was paged loads th e paging radio’s Global ID and clock offset in order to join then master’s piconet. . 2 vCard file format vCard is a file format standard for electronic business cards. vCards are often attached to e-mail messages, but can be exchanged in other ways, such as on the World Wide Web. They can contain name and address information, phone numbers, URLs, logos, photographs, and even audio clips. The vCard or Versitcard was originally proposed in 1995 by the Versit consortium, which consisted of Apple Computer, ATamp;T Technologies (later Lucent), IBM and Siemens.In December 1996 ownership of the format was handed over to the Internet Mail Consortium, a trade association for companies with an interest in Internet e-mail. vCard is accompanied by a proposed standard for exchanging data about forthcoming appointments called vCalendar since superseded by iCalendar; the Internet Mail Consortium has issued a statement that it hopes that all vCalendar developers take advantage of the se new open standards and make their software compatible with both vCalendar 1. and iCalendar. The following is an example of a VCard file containing information for one person: BEGIN:VCARD VERSION:2. 1 N:Gump;Forrest FN:Forrest Gump ORG:Bubba Gump Shrimp Co.

HOW TO BLUEJACK Assuming that you now have a Bluetooth phone in your hands, the first thing to do is to make sure that Bluetooth is enab led.You will need to read the handbook of the particular phone (or PDA etc) that you have but somewhere in the Menu item you will find the item that enables and disabled Bluetooth. Now, remember that Bluetooth only works over short distances, so if you are in the middle of Dartmoor then BlueJacking isn’t going to work for you (unless the sheep have mobile phones these days! ) so you need to find a crowd. BlueJacking is very new so not everyone will have a Bluetooth phone or PDA so the bigger the crowd the more likely you will have of finding a victim’.The Tube (yes, Bluetooth works underground), on the train, in a Cafe or standing in line are all good places to start. You will now need to create a new Contact in your Phone Book – however rather than putting someone’s name in the Name field you write your short message instead – so for example rather than creating a contact called Alan Philips you would write – Hey, you have been BlueJacked! instead (or whatever message you want to send) Now select the new contact and from the Menu of the phone choose Send via Bluetooth.This is a facility available within the Mobile Phone that was designed to send a Contact to someone else – useful in Business when trading names and addresses, however we are now going to use it to send our message that was contained in the Name field of the contact – clever eh? Your phone or PDA will start to search the airwaves for other devices that within range. If you are lucky you will see a list of them appear, or it will say that it cannot find any. If the latter happens then relocate to another crowd or wait a while and try again. If you have a list of found devices then let the fun begin.Unfortunately, almost every Bluetooth enabled device will not yet be configured with a useful name – so you are going to have to guess. Some devices will be called by their Phone manufacturer (e. g. Nokia, Sony) or maybe a random string. T ry one at random and look around to see who grabs their phone and then looks perplexed when they read your message If you want to name your Phone so it appears as a name in the list on a BlueJackers phone see how to name our phone . You can build a library of contacts with predefined messages. 3. 1 Mobile The various steps involve in this are as follows: . First press the 5-way joystick down. 2. Then choose options. 3. Then choose New contact 4. Then in the first line choose your desired message. 5. Then press done. 6. Then go to the contact. 7. Then press options. 8. Then scroll down to send. 9. Then choose Via Bluetooth 10. Then the phone will be searching for enabled Devices. 11. Then press Select 3. 2 Personal computers/laptops 1. Go to contacts in your Address Book program (e. g. Outlook) 2. Create a new contact 3. Enter the message into one of the name’ fields 4. Save the new contact 5. Go to the address book . Right-click on the message/contact 7. Go to action 8. Go to Send to Bluetooth 9. Click on other 10. Select a device from the list and double click on it 3. 3 Software tools The procedure for bluejacking as stated or explained earlier are very long and confusing. To avoid this we have developed some software to do bluejacking in an easier way. So by downloading that software on your personal computer or on your Bluetooth configured mobile phone you can do it directly by just searching the enabled Bluetooth device and send unsolicited messages to them.There are many software tools available in the market and there name is according to their use. Some of them are as follows: 3. 3. 1 Bluespam BlueSpam searches for all discoverable Bluetooth devices and sends a file to them (spams them) if they support OBEX. By default a small text will be send. To customize the message that should be send you need a palm with an SD/MMC card, then you create the directory /PALM/programs/BlueSpam/Send/ and put the file (any type of file will work . jpg is always fun) you would like to send into this directory.BlueSpam also supports backfire, if you put your palm into discoverable and connectable mode, BlueSpam will intercept all connection attempts by other Bluetooth devices and starts sending a message back to the sender. 3. 3. 2. Meeting point Meeting point is the perfect tools to search for Bluetooth devices. You can set your meeting point to a certain channel and meet up with people you’ve not met before. Combine it with any bluejacking tools and have lots of fun. This software is compatible with pocket PC, palm, Windows. 3. 3. 3 Freejack Freejack is compatible to java phone like Nokia N-series. . 3. 4. Easyjacking (eJack) Allows sending of text Messages to other Bluetooth enables devices. 3. 3. 5. Proximitymail 3. 3. 6. Freejack 4. USAGE OF BLUEJACKING Bluejacking can be used in many fields and for various purposes. The main fields where the bluejacking is used are as follows: Busy shopping centre Starbucks Train Station Hig h Street On a train/ tube/ bus Cinema Cafe/ restaurant/ pub Mobile phone shop Electronics shop (e. g. Dixons) The main use of bluejacking tools or bluejacking is in advertising purpose and location based purpose.Advertising on mobile devices has large potential due to the very personal and intimate nature of the devices and high targeting possibilities. We introduce a novel B-MAD system for delivering permission-based location-aware mobile advertisements to mobile phones using Bluetooth positioning and Wireless Application Protocol (WAP) Push. We present a thorough quantitative evaluation of the system in a laboratory environment and qualitative user evaluation in form of a field trial in the real environment of use.Experimental results show that the system provides a viable solution for realizing permission-based mobile advertising. 4. 1 Bluetooth location based system In terms of location proximity detection for mobile phone users the obvious choice is Bluetooth which, despit e previous predictions of its demise, is in fact increasing its growth and Nokia is predicting a year-on year increase of 65% in 2006. There are already a small number of mobile Bluetooth proximity applications in existence which are often described as mobile social software (MoSoSo) and can be viewed as evolutions of Bluejacking.Bluejacking was/is a phenomenon where people exploit the contacts feature on their mobile phone to send messages to other Bluetooth enabled devices in their proximity. Bluejacking evolved into dedicated software applications such as Mobiluck and Nokia Sensor which provided a simpler interface, and in the case of Nokia Sensor, individual profiles could be used to initiate a social introduction. In terms of this particular application it could be regarded as a business orientated application of the Bluejacking phenomenon.Consumers are becoming increasingly aware of the use and benefits of Bluetooth as demonstrated in the widespread use of Bluetooth dongles th rough which the users can connect their desktop machines to these devices. Other initiatives for Bluetooth have been seen in the automotive and medical industries in that manufactures have begun to include Bluetooth access in cars and medical monitoring equipment. According to analysts [11], Bluetooth is currently present in 65% of all mobile phone handsets thus making a system such as the one described in this paper, a very practical and worthwhile scenario.This location based system enables Bluetooth to be used as a means of targeting users with specialized content in a specific area at a given time. For example, users in a supermarket could be informed about a certain discount offer based upon their purchasing habits. Such messages can be sent to all the users in the area with a Bluetooth enabled mobile handset or PDA. In order that the system can service a diverse range of users and devices no client side application is required thus nothing has to be installed. The information is presented in a very familiar and simple form of a text message.Figure 3 shows the basic layout of a system for transmitting messages to all the devices in a given area. The system uses object exchange protocol (OBEX) over Bluetooth to send the information to target devices. Licensed by Bluetooth SIG from IrDA, OBEX has become even more popular than during its original period as means of transferring business details. OBEX is transport neutral, as with the hypertext transfer protocol (HTTP), which means that it can work over almost any other transport layer protocol. OBEX is defined as one of the protocols in Bluetooth and sits over RS232 serial cable emulation (RFCOMM) protocol.Moreover, OBEX is a structured protocol which provides the functionality to separate data and data attributes. A clear definition of each request can be given which helps distinguish one request from another. Use of other protocols such as RFCOMM or logical link control and adaptation protocol (L2CAP) requ ire the applications sending and receiving information to know how the data is sent and when to send the reply. Like extensible markup language (XML) OBEX provides structure to the data being sent in contrast to other protocols such as RFCOMM which basically send bytes. 4. 2 Bluejacking s a market channel Bluetooth offers a new communications channel to marketers. But the technology needs to be respected if they are to avoid alienating consumers according to a white paper from Rainier PR. Stephen Waddington, managing director of Rainier PR, turns wireless sleuth. The marketing industry is never slow to jump on a new communication channel and exploit it for its own ends. The telephone, email, SMS text messaging and the web have all become a standard part of the marketing toolkit, the latter having a marked impact on the way in which organizations communicate with their audiences.Now there is a new mobile communication platform called Bluetooth and both the marketing and technology co mmunity are debating whether it offers a new opportunity to be exploited for marketing gain. 4. 3 Marketing opportunity This mechanism by which messages can be sent between Bluetooth devices – predominantly mobile phones – has provoked discussion within the marketing community as to whether Bluetooth could be used as a promotional communication channel. Bluejacking offers three distinct opportunities for marketers: 1. Viral communicationExploiting communication between consumers to share content such as text, images and Internet references in the same way that brands such as Budweiser, Honda, Trojan Condoms and even John West Salmon, have created multimedia content that has very quickly been circulated around the Internet 2. Community activities Dating or gaming events could be facilitated using Bluetooth as a channel to communicate between participants. The anonymous nature of bluejacking makes is a superb physiological tool for communication between individuals in a localized environment such as a cafe or pub 3. Location based servicesBluejacking could be used to send electronic coupons or promotional messages to consumers as they pass a high street shop or supermarket. To date SMS text messaging has been used with mixed success as a mechanism to send consumer’s location based information Rainier PR believes that viral communication and to a lesser extent event based activities offer the greatest opportunity for bluejacking as a marketing mechanism. Already companies are looking at ways of exploiting the technology in these two areas. London, UK-based TagText has made available a series of urban avatars available free for consumers to send each other.The company is tight lipped about its ultimate product and goals but has done a superb job of raising its profile by making available a series of free media properties. What is clear is that TagText wants consumers to send TagText characters to each other and raise the profile of the company . Herein lies one of the key benefits of Bluetooth. Unlike any other mobile communication mechanism it is absolutely free – there are no subscription charges and no costs associated with sending a message. The rise in text-based bluejacking couldn’t have been more timely for TagText’s launch.Not only can we capitalize on the trend, but using images adds a new dimension that even most bluejackers haven’t yet considered, said Russell Buckley, director and founder of TagText. Buckley admits that Bluejacking would not suit everyone, but for brands that want bleeding edge youth credibility
