Renewable Energy For The Changing World - 1600 Words

Karina Vanous Smith Political Economy 13 January 2015 Renewable Energy for the Changing World Currently, there is a call for alternative energies to replace our harmful energy sources that are bringing the world closer and closer to global warming. As of right now, America’s economy is mostly dependent on destructive fossil fuels for its energy supply. Our country is producing a quarter of the world’s pollution. Usage of fossil fuels has increasingly contributed to the CO2 emissions, which is polluting our environment. It is destroying natural habitats and causing an increase in health problems. If our harmful methods continue, our planet will eventually become uninhabitable. Fossil fuels are considered a nonrenewable resource, which means we are required to find a new and clean renewable energy source. These new energy sources must be readily available for the world’s energy demands. Our vision should focus on environmentally friendly and efficient energies such as wind and solar power. Becoming more dependent on wind and solar power would mean having an infinite amount of energy and create more job opportunities, which would help the world’s economy as well. Americans use wind and solar energy because they are not only environmentally friendly, but are affordable and an abundant source of energy. â€Å"The United States has some of the best wind resources in the world, with enough potential energy to produce nearly 10 times the country s existing power needs† (Clean LineShow MoreRelatedA Brief Note On Hydro Quebec And The Largest Electricity Company1630 Words   |  7 Pageshydropower in the world.

Optimism - 1666 Words

------------------------------------------------- Optimism Optimism is a mental attitude or world view that interprets situations and events as being best (optimized), meaning that in some way for factors that may not be fully comprehended, the present moment is in an optimum state. The concept is typically extended to include the attitude of hope for future conditions unfolding as optimal as well. The more broad concept of optimism is the understanding that all of nature, past, present and future, operates by laws of optimization along the lines of Hamiltons principle of optimization in the realm of physics. This understanding, although criticized by counter views such as pessimism, idealism and realism, leads to a state of mind that†¦show more content†¦He hoped that society would eventually reach the state where calm reason would replace all violence and force, that mind could eventually make matter subservient to it, and that intelligence could discover the secret of immortality. Much of this philosophy is exemplified in the Hou yhnhnms of Jonathan Swifts Gullivers Travels. Panglossianism The term panglossianism describes baseless optimism of the sort exemplified by the beliefs of Pangloss from Voltaires Candide, which are the opposite of his fellow traveller Martins pessimism and emphasis on free will. The phrase panglossian pessimism has been used to describe the pessimistic position that, since this is the best of all possible worlds, it is impossible for anything to get any better. The panglossian paradigm is a term coined by Stephen Jay Gould and Richard Lewontin to refer to the notion that everything has specifically adapted to suit specific purposes. Instead, they argue, accidents and exaptation (the use of old features for new purposes) play an important role in the process of evolution. Some other scientists however argue the implication that many (or most) adaptionists are panglossians is a straw man.

Systematic WHS Planning and Policies

Question: Discuss about the Systematic WHS Planning and Policies. Answer: Introduction The system of WHSMS has been developed to help the organizations to make proper planning and policies regarding the health and safety of the workers in the workplace. In the case of hospitality/bars, it is the duty of the owners to provide a safe system of work by communicating with their employees and implementing the safe working environment. In the given case the place Tthai restaurant can handle 100 people on a daily basis, includes the service of taking away, and dine in. The need of WHSMS in the restaurant based on certain assumptions is as follows: WHSMS gives assurance of safe and healthy workplace. The owner can assure this by installing security cameras so that any misful act done in the restaurant can be detected quickly. It helps in identifying the hazards and controls the risk of occurrence of accidents (Underhill 2013). Accidents may occur due to leakage of the gas cylinder, short circuit, and various another factors. The management should provide proper training to the workers regarding this issue. It provides proper information and training to all the workers of the organization so that they can work efficiently. It reviews the health and safety system of the body so that the person can handle any accidents. It minimizes the risk of the work stoppage by providing the adequate measures so that the individual can easily calculate its leftover stock. It improves the opportunity of business by developing its reputation among the customers and other associates. The positive performance indicators, which can be used by the person for its success, are as follows: Conducting workplace scrutiny: It becomes necessary to check the workplace at least on a weekly basis to derive the idea about the loopholes of the organization. The loopholes can be in the field of quality of the food supplied to the customers, the hygiene issues, misbehavior with the clients or staff members. Proper feedback register is to be maintained by the management so that they can improve in the weaker section of their organization. Organizing health check-up for the staff members on weekly or monthly basis should be arranged so that the health related issues of the team could be solved. Checking training needs so that the seniors can take adequate measures in this field. Monitoring regulatory requirements: It is necessary for the business to comply with the proper law and order to achieve success in the future. So, to (or "intending to") attracting more customers they should not practice any Mala Fide activities like reduction in tax percentage, not issuing proper bills to them, and so on. The Proper register is needed to be maintained by the management regarding this matter. The barriers to implementation of the policies of WHSMS occur when staff members ignore the need of health and safety policies in their working environment (Lamm 2014). In this case, it is the duty of the management to make them understand the systems by providing proper guidelines and training. When the safety cost becomes too high, it is important for the management can cut off the other expenses to bear the security cost as if they can reduce some of the working staff, they can lower the cost of electricity, and so on. When no discussion is made regarding the health and safety measures in the organization with the members, it becomes necessary for the management to arrange a meeting and discuss the matter. They can make insurance policies for their staff members who can benefit them shortly. When the system becomes too complicated, the workers are unable to handle the safety system efficiently. It is quite common to say that each organization has some elder working staff they will not be able to understand the system effectively. When the cure becomes involved: Finding the cure for any situation is necessary. Therefore, the management needs to discuss this matter and find the suitable cure for the problem. They can appoint some expertise or consult the issue with the person who has proper knowledge in this field. Conclusion: It can be concluded that the restaurant Tthai has to adopt all the above-mentioned things to run the business smoothly. The duty of management towards them is to appoint that person who has proper knowledge in this field and can handle the system efficiently. In other words, they can change the elder staff with the younger ones.

Written Communications Essay Example Essay Example

Written Communications Essay Example Paper Written Communications Essay Introduction Over the years, written communication has remained the most effective mode of communication. This has been the case due to its immediate ability to reach more people and retain evidence for future references (Richard Robertson, 200, pp. 56). Since inception, this form of communication has developed greatly with major improvements in efficiency. It entails communication through written symbols by or between people. Written communication acts as the main interlink in both local and international agreements that forms the major binding organs between nations and business entities. Its discovery and development has therefore been described as one of the most important aspect of all times. The role of research and planning. To ensure effective written communication, prior research and planning must be undertaken as the major platform for establishing factual information for later analysis and presentation. This prior stage assists an individual in selecting the proper topic that rhymes w ith the main issues and information in the text (Uma, 2006, pp. 252). Good topic attracts the attention of the reader on first sight by shedding clear light on what to expect in the body of the written text. To add to that, this stage ensures that the writer has gathered and consulted enough and relevant sources that will adequately support the subsequent text. Of greater importance, this stage ensures that the text prepared is of high quality and strong convincing power by carefully surveying and comparing the primary and secondary materials against sequential development. As a result, this stage guarantees validity of the information to be displayed in the main text. Written Communications Essay Body Paragraphs After careful selection of the topic to be used in the text, planning establishes calculative and well flowing ideologies with necessary breakdown of the text that reflects immediate sub text with the main orientation towards the theme. It is therefore important to break the text into major headings and minor ones that assist the reader in easier comprehension of the information displayed systematically. Also, planning later aids in writing drafts, revising them and proof reading the whole document before releasing it to the prospective readers. Through ample and clear planning of document it is easy to avoid plagiarism and reinventing the wheel (Richard Kate, 2008, pp. 10). Business writing style: plain English The essence of business writing is to ensure precise and concise communication is effected to the readers. Therefore, plain English ensures that strong feedback mechanism is cultivated in the readers’ perspective making it easy to ensure a strong dual-system to comple te the cycle. Through plain English efficiency and equity of the readers is easily enhanced. l Language. Use of words in the text should be highly simplified for better understanding by the readers. The language should be framed in a manner that captures ideas and feelings of the event presented in the text. Jargons should be avoided and clear explanations given where they are inevitable. The ability of the text to be self perpetuating acts as a major point in making the reader go through the document faster and capture all the aspects displayed. l Sentences. Just like the simple language, sentences should also be simple for easier understanding. Simple sentences ensure that there is no hidden meaning that may require struggling or possible consultations to understand. Where compound sentences are to be used, direct conjunction of related ideas must be harmonized without altering the main concept (Harvard Business School, 2007, pp. 175). l Paragraphs. To effectively communicate to t he readers, it is important to ensure that similar points are grouped together in the same paragraphs. The paragraphs should however be adequately summarized without compromising the intrinsic quality and content in line with the major theme. To add to that, ideas must be arranged in a flowing rhythm that creates the correct mood for the reader therefore pushing him to read the next section. l Tone. Tone involves the mood expressed by a piece of text as the reader goes though it. The text is supposed to reflect the urgency, necessity and importance of the issue being discussed in it (Yunxia, 2007, p. 215). It ensures that the text have high effectiveness as the recipients easily identify with its demands. Therefore, the correct tone is an imperative aspect in ensuring that immediate and correct feedback is generated. However, care should be taken to ensure the correct tone is implicated and therefore avoid unnecessary reactions. Academic writing. Academic writing entails production of written materials that are highly objective in approach, clearly states the importance of the topic in relation to the business context and organizes the work with strong analysis and supportive materials (Harvard Business School, 2007, pp. 175). Also, it avoids generalization while trying to put forward possible methods that can be employed in addressing the immediate situation or problem. Steps in academic writing. l Clear and logical thinking Creative and critical evaluation of the materials being put down enhances the validity and thus improves the chances of positive responses from the readers of the text. All the principles and considerations in the text must have adequate premises that support it thereby avoiding possible confrontation and ensuring better flow of the same information through out the text. Deductive reasoning that gives clear indications and scientific interlink of various aspects acts to solidify the convincing power of the written information to the reade r. Wider perspectives with inclusive illustration inform of flowcharts and graphs reduce possible doubts from the readers and ensure that the correct tone is maintained. To ensure high quality work, generalization should be totally eliminated (Glenn, 2008. pp. 118-119). l Structure and content. As indicated earlier, business communication demands precision and accuracy for the text as well as the ideas presented in the text. Therefore, after careful analysis of the various phenomena and data related to the text being composed, a strong structure that is as self explanatory as possible should be employed. This is easily done through interpretations and presentations in diagrammatic format. Academic wittings demands extensive research that clearly supports different perspectives and logically indicating the reasoning behind the identified choice (Dwyer, 2002, p. 58). Therefore, the document should assume a congruent and harmonic model that introduces the idea with a thesis statement w hich shows the stand of the writer. Then a consequent body with the prior indicated subsections and a conclusion embossed with recommendations for the particular problem. Finally, clear summary should be given as a condensed form of the whole document to the reader. Besides reminding the reader of the prior concepts, it assists in emphasizing possible aspects that may have been skipped. l Writing techniques. After collection, analysis and careful reasoning of all the relevant information that should be communicated to the reader, specific techniques should be employed to effectively translate all the information to the desired mode that will be eventually distributed to the reader. As previously indicated in the writing styles, signaling devices must be well selected to capture the attention and the essence of the text (Perry, 2008, pp. 82-83). Depending with the desired outcome there should be strong matching emphasis between and among the different aspects interlinking the text. l Revising and editing Revising and editing involves close evaluation of the written work before it can be certified to be released to the readers. It entails careful evaluation of all the aspects in the document (Charles et al, 2008, pp.231-232). Therefore, it acts as one of the final stages that counter checks major cohesion and harmony of all the ideas that are required to be communicated by the paper. It has been described as one of the most important stages in the writing process by proofing that there are no errors or overlapping considerations. Communication online Presently advancements in technologies have taken the level of written communication a notch higher through making it easier to avail the written material to more people as well as collecting views and ideas on a global scale. Varying software enables various people to share data and therefore interact effectively without necessarily meeting physically. Due to the need for efficacy in communication special sites lik e my space, and face book have become very popular. Internet has therefore made work far much easier since it gives a lot of information necessary for the preparation of final documents by the writer. Sites like Amazon.com provides majority of the latest published work for evaluation and consideration by the writer. For effective communication online, the writer must have an electronic mail that easily links the written work to the prospective readers at various places. This system demands that the writer and the reader be online to be able to communicate effectively (Mann, Stewart, 2000. pp. 45-47). To add to that the reader must make sure that the document is put in the correct format that the readers are able to decode with ease for efficiency. Besides, the document should be secured and protected from editing and altering the core concepts by possible business rivals who may have aces to it. Conclusion. Written communication has remained the most effective form of communication since inception. It acts as the major way of ensuring that the writer and the reader are in harmony and also gives a direct opportunity for storing varying types of information after the process. Therefore, it becomes easy to evaluate and compare facts about a given piece of information and its effects at a later date with main view of improving the subsequent forms. Careful preparation however must always be upheld for efficacy at various moments of the documents preparation. As indicated earlier, businesses must use facts and thus all the relevant material must be considered and evaluated for clarity and to reflect the real situation as it is expected by the writer. Business written communication should follow the academic writing specifications that ensure clear focus and direction is given through out the document. For effective online written communication, both the reader and the writer must interact and relay feedback to each other to assess the response. Finally, increased care must be taken to ensure safety of the written information especially with the online system.

An Overview of Music Censorship essays

An Overview of Music Censorship essays Because the First Amendment guarantees freedom of speech, some opponents of music censorship believe that the courts can force a store to sell albums its management deems objectionable or forbid groups from burning records. The Supreme Court, however, can only step in if someone appeals a government decision, rather than a community one, to censor music; such appeals rarely reach the highest court in the land, since individual state governments can devise their own obscenity laws and penalties for violating them. Fighting censorship thus poses a catch-22, as musicians and concerned citizens can't deny a school's right to ban a concert on its premises and would face an uphill battle overturning a state's mandates on decency. Music censorship first reared its head in the 1950s, when rock and roll's growing influence threatened white, middle-class values. The 1960s saw the FBI's involvement in musician's personal and political lives, as officials began keeping tabs on Woody Guthrie, Bob Dylan, and John Lennon. Song references to sex and drugs tormented censors throughout the '60s and '70s, eventually giving way to hysteria over lyrics promoting suicide and devil worship in the 1980s. In 1985, the Parents Music Resource Center, led by a cadre of politicians' wives, called for the recording industry to place Parental Advisory stickers on potentially offensive albums. Instead of quelling concerns, the stickers unleashed a barrage of state laws that required retailers to regulate distribution or pay the price (a hefty fee or even jail time). In the meantime, the banned albums benefited from the notoriety. Ultimately, community and federal censors have threatened civil liberties while entangling their organizations in a costly fight to maintain an ambiguous definition of decency. Albums with explicit lyrics or content started having black and white parental advisories on them in 1994 (riaa.org/Parents-Advisory-4.cfm). Are t...

Samuel Slater and the Textile Revolution

Samuel Slater and the Textile Revolution Samuel Slater is an American inventor who was born on June 9, 1768.  He built several successful cotton mills in New England and established the town of Slatersville, Rhode Island.  His accomplishments have led many to consider him to be the Father of American Industry and the Founder of the American Industrial Revolution.   Coming to America During the United States early years,  Benjamin Franklin and the Pennsylvania Society for the Encouragement of Manufactures and Useful Arts offered cash prizes for any inventions that improved the textile industry in America. At the time, Slater was a young man living In Milford, England who heard that inventive genius was rewarded in America and decided to emigrate. At the age of 14, he had been an apprentice to Jedediah Strutt, a partner of Richard Arkwright  and  was employed in the counting-house and the textile mill, where he learned a lot about the textile business. Slater defied the British law against the emigration of textile workers in order to seek his fortune in America. He arrived in New York in 1789  and wrote to Moses Brown of Pawtucket to offer his services as a textile expert. Brown invited Slater to Pawtucket to see whether he could run the spindles that Brown had bought from the men of Providence. If thou canst do what thou sayest, wrote Brown, I invite thee to come to Rhode Island. Arriving in Pawtucket in 1790, Slater declared the machines worthless and convinced Almy and Brown that he knew the textile business enough to him a partner. Without drawings or models of any English textile machinery, he proceeded to build machines himself. On December 20, 1790, Slater had built carding, drawing, roving machines and two seventy-two spindled spinning frames. A water-wheel taken from an old mill furnished the power. Slaters new machinery worked and worked well. Spinning Mills and the Textile Revolution This was the birth of the spinning industry in the United States. The new textile mill dubbed the Old Factory was built at Pawtucket in 1793. Five years later, Slater and others built a second mill. And in 1806, after Slater was joined by his brother, he built another. Workmen came to work for Slater solely to learn about his machines and then left him to set up textile mills for themselves. Mills were built not only in New England but in other States. By 1809, there were 62 spinning mills in operation in the country, with thirty-one thousand spindles and twenty-five more mills being built or in the planning stages. Soon enough, the industry was firmly established in the United States. The yarn was sold to housewives for domestic use or  to professional weavers who made cloth for sale. This industry continued for years. Not only in New England, but also in those other parts of the country where spinning machinery had been introduced. In 1791, Slater married  Hannah Wilkinson, who would go on to invent two-ply thread and become the first American woman to receive a patent.​ ​Slater and Hannah had 10 children together, although four died during infancy. Hannah Slater died in 1812 from complications of childbirth, leaving her husband with six young children to raise. Slater would marry for a second time in 1817 to a widow named Esther Parkinson.

Management Analysis - Coursework Example The managing director, however, does not participate in preparing financial statements because the report is considered supplementary information (Finkler et al., 2013, p.477). However, compiling financial statements requires the assistance of managing directors in compliance with GAAP (Generally Accepted Accounting Principles) outlined in GASB policies on management discussions and analysis. Guidelines on management discussions and analysis require managing directors to access readable documents for government enquiry on financial services based on relevant facts, conditions and decisions. It involves comparisons of different years based on the government’s gathered information on financial issues (Finkler et al., 2013, p.476). Furthermore, discussions must include the government’s general economic positions with outcomes of operations to assist the public in assessing financial positions and improvement of altered results on the year’s activities.

Human Sexuality and Proponents of the Religious Viewpoint Essay

Human Sexuality and Proponents of the Religious Viewpoint - Essay Example By discriminating against homosexual, society becomes oblivious to the different factors that result in sexual attraction. Furthermore, the United States has one of the most elaborate bills of rights, one emulated by several democracies all over the world. It, therefore, becomes redundant for such a country to formulate and implement policies that stifle the very human rights that its bill of rights seek to defend. The proponents of the abolition of gay marriages are often religious leaders who continue to teach their followers that homosexuality is a sin and therefore not acceptable. They consist of both a section of Christians and their Muslim counterparts. While Christians continue to face division on the issue with several clerics already endorsing the gay marriages, their Muslim counterparts continue to maintain a more stringent view to the issue of homosexuality. Most Islamic states outlaw such acts thereby denying their population the freedom of choice. However, those in Ameri can society enjoy the liberal human rights that safeguard the interest of every human (Shanty and Patit 22). Religion is an important aspect of human life. Religion one of the most essential social pillars that hold the social fabric in societies together, it provides a benchmark with which people assess their behaviours thereby resulting in a cohesive society in which everyone enjoys equality. The American constitution safeguards the freedom of religion and worship thereby allowing the population to own different religions and viewpoints on their social life.

Rebeccas Structure Essay Example for Free

Rebeccas Structure Essay Explain the effectiveness of the structure of the text, Rebecca Daphne du Maurier’s Rebecca is structured in a circular form, which is effective in displaying elements of the gothic genre and producing a sense of mystery and ambiguity. The fact that details are revealed gradually creates tension, and a desire to know, so that by the end of the novel the audience is satisfied with the complete story, despite the horrific truth regarding Rebecca’s murder. The text virtually revolves around a murder By using a BAB form, with a reference to the ending at the beginning of the novel, a sense of confusion and abstruseness is evoked among readers. The first chapter, in which the narrator supernaturally returns to Manderley, relives her experiences and mourns for the loss of such an exquisite property, is perplexing for the reader as the scene, characters and setting have not been established. This causes the audience to disregard the first chapter, as the second chapter begins with an entirely different setting and mood. Upon reaching the end of the novel, the reader grasps the meaning of the dream sequence, and the forgotten abstruseness is resolved. The audience is left content with all details of the story revealed, but, like most gothic tales, also chilled and unsettled with the shocking conclusion. Rebecca shows elements of the horror genre through the structure, in which the details are revealed throughout the story, by being analogous to many crime shows of today. In television programs such as CSI, a section of the fictional offense is shown, after which the team investigates the murder or other wrongdoing, and eventually discovers the callous yet complete truth. This order of events matches exactly with those in Rebecca, and it has the effect that we have an idea of the story, but become alarmed yet intrigued as more shocking details are revealed. The text is structured in a way that the scene is set and elaborated on throughout the book as the story and events take place, which causes the reader to experience confusion and a sense of incompetence. The fact that we are put in the place of the speaker allows us to experience everything she feels, knows and says. The narrator’s lack of knowledge concerning Rebecca’s death and murder is unnerving, as it makes us feel just as naive and oblivious as Mrs. de Winter. This is relevant to the gothic genre as it plays on the idea of being put in someone else’s place, which seems supernatural and ghost-like, as if the murder is something we can only learn about through the narrator, as everyone else is already in the know. This idea is further explored when Mrs. de Winter goes to live at Manderley, and unintentionally takes Rebecca’s place. The ingenuousness of the narrator, and how she gradually learns the truth about the murder, allows us to relate, and displays the ghost-like element of the gothic genre. In conclusion, the structure of Rebecca is effective in exemplifying the gothic genre because it references the end of the book at the beginning which creates confusion and mystery. Its effect on the readers is significant because it follows the structure of many crime shows, and makes us feel clueless, like the narrator.

Grade Retention Essay example -- essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Grade retention, better known as â€Å"staying back†, â€Å"being held back† or â€Å"repeating†, has been the topic of much debate within the educational system. The controversy which surrounds this long-standing issue has been reinforced by such topics as the recent endorsement of academic standards. Research indicates that â€Å"the rate of retention has increased by approximately 40% in the last 20 years with as many as 15% of all American students held back each year and 30-50% held back at least once before ninth grade† (Dawson, 1998). These discouraging statistics pose copious problems within a school system. The difficulties can be appreciated at the organizational level, as well as inside the classroom and, most troubling, within the individual students. The consequences, both positive and negative, reverberate throughout the school system. Grades retention is an issue which requires a prodigious amount of examination and shou ld be considered carefully and thoroughly.   Ã‚  Ã‚  Ã‚  Ã‚  Formally, grade retention is defined as the practice of requiring a student who has been in a given grade level for a full school year to return at that level for a subsequent year (Jackson, 1975). Unofficially, the practice is employed as a tool to enhance the academic or developmental growth for students who are unable to meet the curriculum requirements due to a variety of reasons. These reasons can include decreased cognitive functioning, physical immaturity, social-emotional difficulties and failure to pass standardized assessments. A child may be considered for retention if he has poor academic skills, is small in stature, is the youngest in the class, has moved frequently, has been absent repeatedly, does poorly on prescreening assessments or has limited English-language skills (Robertson, 1997). Additionally, the typical profile of a retained child is more likely to reveal an elementary school-aged student who is a black or Hispanic male with a late birthd ay, developmental delay, attentional problems, low socioeconomic status, single-parent household with a parent who either does not or cannot intervene on behalf of the child (Robertson, 1997; Mattison, 2000).

Strategic Drift

Identify four organisations that, in your view, are in the different phases of strategic drift (see Exhibit 5. 2). Justify your selection. Strategic drift, as defined by Gerry Johnson in Exploring Corporate Strategy, is the tendency to develop strategies incrementally on the basis of historical and cultural influences, while failing to keep pace with a changing environment. In such circumstances the strategy of the organization gradually drifts away from the realities of its environment and towards an internally determined view of the world of management. Strategic drift occurs when a company, especially one that has enjoyed considerable success, responds far too slowly to changes in the external environment and continues with the strategy that once served it very well. There are four phases in strategic drift; incremental change (phase 1), strategic drift (phase 2), flux (phase 3) and transformational change or death (phase 4). Phase 1 is characterized by relatively long periods during which strategies are either unchanged or change incrementally. This change is generally in keeping with the environment or may have slight variations around a successful theme as the company avoids drifting too far from some past successes. In phase 2 the environment grows at a faster rate than the firm’s strategies. This may occur for several reasons, that is ; while one may be aware that changes are happening, the extent may not be so easily appreciated except in hindsight or as reflected through the financials; it could also be that while the changes are observed they are interpreted in terms of the familiar thus resulting in the wrong conclusion being drawn. There is also the situation where although the firm may see the environmental drift, it refuses to align as it binds itself to the successful strategies of the past. These strategies become the company’s core around which it revolves and has its competitive advantage. Another contributory factor can also be unwillingness of the firm to alter the current relationships with suppliers, customer base or the internal skills to align with the market. Phase 3 may be a period of flux as management pressured to alter the firm’s strategies in response to downturn in profit does so but not in any clear direction. Internal rivalry may be high as solutions are sought to determine which strategy to follow. There may also be loss of confidence in the company resulting in lowering share prices. As the situation worsens there are three options in phase 4. The firm can die, be taken over by another organization or simply go through a period of transformational change. Motorola found itself in phase 4 of the strategic drift in the late 90’s as in response to depressed profits it was forced to conduct a series of layoffs, restructures and restrategising before transforming. According to Sydney Finkelstein article on â€Å"Why smart executives fail†, Motorola which was founded in 1928 has had a long tradition of technological innovations. It solidified its reputation as a world leader in this area through innovation with the television, pager, microprocessor, analogue phone among other things. Motorola’s first cellular system began commercial operation in 1983 with them becoming the world top cellular phone supplier shortly thereafter. They claimed 60 per cent of the US mobile market, revenues growing at an average of 27 percent to $27 billion in 1994, while net income surged 58 per cent a year to $1. billion. During this period, although digital mobile technology was introduced, it was not embraced by Motorola even after receiving several signals from the market. The market signals included – direct prodding by their customers requesting that they provide the new technology especially based on the benefits offered; increase in royal ty income from digital patent it licensed to Nokia and Erikson and finally the falling market shares and profit. Motorola’s shares dip to 34 percent in the early 1998’s, while Nokia’s share went from 11 per cent to 34 per cent during the same time period. That same year Motorola laid off 20,000 employees. Motorola was fully poised with the potential to maintaining their position as market leader using digital technology however they chose to rely on internal forecasting models that predicted carriers would be better off with analogue phones rather than digital. Sony whose mission statement was ‘a clever company that would make new high technology products in ingenious ways’ aggressively marketed its hardware entering the big league when it formed a joint venture with CBS Records in 1975 with the launch of the new technology – the Betamax home videocassette recorder. Within two years a new videocassette recorder (VCR) made by it arch-rival Matsushita using the VHS standard became the product of choice for consumers. This happened as Sony was too busy defending the hardware than marketing and creating customers. Matsushita, on the other hand, aggressively aligned electronics firms to their brand so that when motion picture studios began to release a larger number of their library titles VHS was the format of choice. ‘We didn’t put enough effort into making a family. The other side, coming later, made a family’, founder Akio Morita later stated. Sony also concluded that the compelling reason for the purchase of hardware is software. Resulting from lessons learnt from competition with arch rival Matsushita, Sony adjusted their strategy. Consequently, convinced that its record library had helped guarantee the success of the Compact Disc, Sony looked to CBS Records to provide the software necessary to ensure the success of its new Digital Audio Tape. In the years that followed Sony acquired expensive movie studios to showcase their impressive arsenal of hardware. As much attention was not paid to the American management team and the lavish spending spree on renovation production, management, and television ballooned. Overheads increased by 50 per cent to $300 million by 1991, some $60 million greater than other major studios, and its $700 million production budget were nearly twice that of its competitors. The average Sony motion picture cost $40 million versus the industry average of $28 million. In November 1994 Sony announced a $3. 2 billion write-off related to Columbia Pictures which wiped out nearly 25 per cent of Sony’s shareholders’ equity. It was not until Sony found itself here in phase 3 of the strategic, drift having major decline in shareholder values, that it restructured its management team and strategies. Wang Labs based on strategies created in an attempt to avoid the mistakes of the past found itself in phase 4 of the strategic drift as it filed for bankruptcy in 1992. An Wang, an inventor and innovator, sold several of his creations to companies who used them to make products for commercial uses. Resulting from one such deal with IBM in 1956, Wang’s feeling of being cheated by the computer giant biased his future decisions towards them. Starting from the late 80’s Wang Labs lost out when the world shifted from using word processors to PC, however they were blinded by their love for the word processors and made major losses as IBM took the PC to the market. Wang could have raise capital by issuing shares however because he felt that he had given up too much of the company in a similar past transaction he refused and instead opted to seek loans According to Paul Golding, prior to 1999 the Jamaican telecommunications sector was dominated by Cable and Wireless Jamaica (C&WJ), which changed its name in 2008 to LIME (Landline Internet Mobile, Entertainment). In 1988 the company was granted five exclusive licenses each for 25 years, which would be valid until 2013, with options for extensions for a further 25 years. The licenses made C&WJ the sole provider of the island’s domestic and international telephone service and guaranteed an after-tax rate of return of 17. 5% – 20%. C&WJ was quite comfortable with the strategies they employed especially as they were a monopoly in these early years. This resulted in the organization being stuck in phase 1 as they became complacent, relying on the same old strategies as technology boomed globally. They were â€Å"out of touch† with customer demand and the untapped potential of the market. Liberalization of the telecommunications market commenced with the granting of two new carrier licenses for the provision of domestic mobile voice, data, and information services. In April 2001 Digicel launched its mobile telecommunication company in Jamaica. Rates rose from 4 per cent in 2001 (Digicel’s launch year) to close to 100 per cent today – making it one of the most highly penetrated countries in the world and driving a grassroots level ICT development across Jamaica. Of the less than 2. million local population, Digicel Jamaica has 2 million customers, representing a 75% market share. Additionally, scores of small entrepreneurs owe their successes to a reliance on their Digicel phones, especially in areas where there were no previous mobile signals by the competition. On October 27th, Digicel announced its intention to move its Jamaica and Group offices to a bra nd new facility on the waterfront in downtown Kingston, demonstrating its commitment to spearhead the rejuvenation of this area of the capital city of the first country in which Digicel launched back in 2001. In April 2001, when Digicel launched its GSM mobile service in Jamaica, the company anticipated reaching the 100,000 customer plateau by the end of its first year in operation. Instead, it hit the 100,000 mark a mere 100 days after launch. Never before in the country’s history of mobile telecommunications had such tremendous growth been seen in a network, as Digicel broke record after record on its way to surpassing its major competitor as the mobile provider with the largest customer base in the island. It took LIME, its major competitor approximately 10 years to reach the 400,000 customer mark. In comparison, it took Digicel about 13 months to reach the same figure. Digicel's customer base in 2010 was over 2. 1 million customers in a population of 2. 8 million. Digicel raised the bar where an acceptable level of network coverage was concerned. Jamaicans living in rural parishes finally had a genuine option for mobile communications. With an island-wide network of over 1,000 cellular towers spread across all 14 parishes, Digicel firmly established itself as the mobile provider with the premier network coverage across the country. Digicel currently appears to be in Phase 2 of the strategic drift as its strategy of providing islandwide service has materialised and it continues to be poised towards supplying any further required hardware. However there is growing concern that Digicel needs to review its customer service as well as its rates. If you really want to understand a company, you need to understand its history and culture. In analyzing an organization one of the most common flaws is to disregard the past in trying to make sense of the present. Culture is also a major component of history, as is highlighted with Motorola that is known as an engineering-driven company. It is likened in its mindset to an ‘internal think-tank’, focused on the market while customers are secondary. Digicel is also similar in this regards as its main focus appears to be on the hardware and to a lesser extent the customer. Motorola’s had an insular culture where its workforce had a ‘fortress mentality, cut off from reality, in-bred, with tremendous self-confidence, and a lack of concern with the outside world’. One former CEO stated, ‘every time we stumble significantly it is because we have been so successful in one generation of the technology that we don’t focus on replacing ourselves with the next technology quick enough’ People make sense of new issues in the context of past issues; they are likely to address a problem in much the same way as they dealt with a previous similar one. Moreover, they are likely to search for evidence that supports those inclinations. So some data will be seen as more important than other data, and some may not be taken on board at all. The important points are: * The interpretation of events and issues in terms of prior experience is inevitable. The idea that managers approach strategic problems and issues entirely dispassionately and objectively is unrealistic. * Such interpretation and bias arise from experience of the past, not least with regard to what is seen to have worked or given rise to problems. So the future is likely to be made sense of in terms of the past. As with individuals, so also with groups – managers do not operate purely as individuals; they work and interact with others, and at the collective level, too, there are reasons to expect experience to count. This is reflected in the taken-for-granted assumptions and ingrained organizational routines that are collectively referred to as ‘organizational culture’. Such taken-for-granted assumptions and routines can be especially important as an influence on the development of organizational strategy. For a group or organization to operate effectively, there has to be a generally accepted set of assumptions which in effect, represents the collective experience without which people would have to ‘reinvent their world’ for different circumstances. As with individual experience, this shared understanding allows the collective experience gathered over years to be brought to bear to make sense of a given situation, to inform a likely course of action, and to gauge the likelihood of the latter’s success. Such collective thinking typically stretches even beyond the organization. Managers may assume that they can manage the environment, but the evidence is that the environment largely determines managerial action. If managers sensitize themselves to the influence of the history of their organisation they stand a better chance of better appreciating their current strategy and may be able to detect and avoid strategic drift. Managers would more likely to be able to question the extent to which the strategy they are seeking to develop is usefully informed by that history as distinct from being driven or captured by it.

Cell phone use while driving: a literature review and recommendations Essay

1. Introduction Cellular telephones (cell phones) were first introduced in the United States in the mid-1980s, and their use has since experienced explosive growth. Today there are more than 262 million cell phone subscribers, representing 84 percent of the United States population. Cell phone technology has become very useful for people on the move, which is demonstrated by surveys that show that the majority of users reported using their phones while driving. Cell phone use by drivers, although difficult to quantify, has been estimated through observational data by the federal government at six percent of drivers in 2007 (IIHS, 2006). This rate means that at any moment during the day, one million passenger vehicles in the United State are being driven by people on hand-held cell phones. Further analysis of these statistics show that women are more likely to be on their phones while driving; eight percent of women use cell phones while driving compared to five percent of their male counterparts. Also of importance, this data found that young drivers (16-24 years old) were most likely to be on their cell phones at 10 percent compared to six percent of those aged 2569 and one percent of drivers 70 and older (see Figure 1). Public perception of the dangers of cell phone use while driving seems to coincide with common sense and experience, but common practice does not. In a survey done by Nationwide Insurance (IIHS, 2008), four out of five surveyed cell phone owners admitted to driving while distracted. Even though almost half of the surveyed people consider cell phone use to be the most dangerous distraction, 98 percent of the drivers consider themselves to be safe drivers. An interesting result of the survey was that almost two-thirds of cell phone owners say they were expected by family, friends or employers to always be reachable by phone or other communication device. Among young drivers in this survey, 40 percent said they send or read text messages along with other activities while driving in order to â€Å"remain connected† (IIHS, 2008). Another survey of only teenage drivers conducted by State Farm Insurance, found that only 25 percent viewed cell phone use while driving as dangerous. Almost 80 percent, however, recognized that texting on cell phones while driving was risky (IIHS, 2008). The rate at which young drivers are most likely to be using cell phones while driving, along with their attitude towards the perceived risk of using such devices, is concerning because this group is already at the highest risk for collisions even without these distractions. A survey conducted by AAA and Seventeen magazine found that 46 percent of drivers 16 and 17 years old said that they text message while driving. This is a profound statistic because 37 percent of the same teenagers said that they believed that text messaging was the most dangerous driver distraction (Quain, 2007). 2. Quantifying Cell Phone Usage and Crash Risk Drivers’ attentiveness has been a concern since the invention of the automobile. As technology increases, the number of driver distractions increases. Each year, more than 42,000 people are killed, more than 3 million are injured, and more than 6 million collisions occur on roads in the United States (IIHS, 2006). Estimates have attributed between 30-50 percent of collisions to distracted drivers, resulting in huge amount of societal cost (Cohen, 2003). Although common sense and experience tells us that using cell phones while driving is dangerous, a number of studies are devoted to quantifying the exact risk associated with using a cell phone while driving. Since the mid-1990s, around 120 studies have attempted to validate a common conception: using a cell phone while driving is a distraction and therefore increases crash risk (IIHS, 2008). The literature on this subject investigates various relationships between cell phone use and accident risk. These studies can be separated into three general groups: epidemiological studies, experimental studies, and real-world studies. Epidemiological studies examine real-world accident data and cell phone records to draw conclusions based on the relationship between the two. Behavioral and experimental studies attempt to measure some cognitive effect of cell phone use on normal driving functions such as visual attention, following distance, reaction time, and other driving tasks. Real-world studies attempt to show how real-world situations either justify or disprove the other data. Before discussing selected studies, a summary of the general conclusions from each type of study is presented below: (a) Epidemiological Studies: Studies that analyze the relationship between cell phone use and increased crash risk using case studies where people have been in actual accident. Researchers have concluded that the use of cell phones while driving significantly increases the risk of collision (Ontario Medical Association, 2008). (b) Experimental and Behavioral Studies: These studies have been able to demonstrate that having a conversation on a cell phone is cognitively distracting and causes deterioration in driving performance. These studies also confirm the finding of the epidemiological studies that when driving performance is affected negatively, an increased crash risk is observed (Ontario Medical Association, 2008). (c) Real-World Studies: These studies are observations of test subjects that are monitored while in the field. Conclusions are drawn based on the observed data and are a reflection of actual events. The real-world studies have proven that the single most dangerous driver distraction is cell phone use. 2.1 Epidemiological Studies Epidemiological studies have attempted to measure the association of cell phone use with the risk of collision. They examine accident data and cell phone records to obtain a correlation, resulting in a relationship between cell phone use and accident risk. The following review focuses on three epidemiological studies that indicate cell phone use is associated with an increase risk of collision. 2.1.1 Cellular Phones and Traffic Accidents, 1996 In an early study in 1996, Violanti and Marshall used a case-controlled design study where they selected 100 random drivers that had been involved in crashes in the previous two years and compared them against another group of 100 randomly selected drivers who had not been involved in crashes in the previous 10 years. The study concluded that using a cell phone for 50 minutes per month resulted in a collision risk 5.59 times greater than not using a cell phone at all. In this study, the risk ratio is statistically significant, but the confidence limits were large. The obvious limitations of this study are: (1) small number of cell phone users in the sample; (2) selection bias; and (3) lack of evidence that the cell phone users were using their phones at the time of the collision. 2.1.2 Association between Cellular Telephone Calls and Motor Vehicle Collisions, 1997 Redelmeier and Tibshirani (1997) conducted the most quoted epidemiological study of cell phone use and increased crash risk in 1997. This research was a case cross-over design, where each subject served as his/her own control. The study included 699 drivers who had been involved in a collision and who owned cell phones. The authors used five-minute intervals of time before the time of the collision, and compared those against the same time on the previous day. The authors were able to conclude that the risk of collision was approximately four times higher than when the same subjects were not using their cell phones. The only significant limitation to this study is that collision times are estimated. There exists the possibility that cell phone use was a post-collision call instead of a pre-collision call. The authors made a conscious effort to eliminate calls that were precipitated by the collision by identifying 9-1-1 calls and through thorough questioning of the drivers. 2.1.3 Wireless Telephones and the Risk of Road Accidents, 2001 Laberge and Nadeau conducted an epidemiological study in Quebec in 2001. This study was based on a self-reported questionnaire from a sample of 36,079 participants, of which 35 percent had records with cellular telephone providers. Taking into account only age and year of observation, cell phone users had a 38 percent higher risk of collisions than non-users. Including additional constraints, such as miles driven and driving habits increased the relative risk by 11 percent for males and 21 percent for females. The authors also applied the case cross-over design used by Redelmeier and Tibshirani to their data. This method produced a relative risk of being in a crash while using a cell phone at 5.13 times that of a non-user. However, the authors concluded that this case cross-over design over-estimates the risk, and determined that a more realistic risk of collision is around 1.3-1.4 times that of a non-user. 2.2 Experimental and Behavioral Studies The majority of the literature reports on experimental and behavior studies examine the impact of cell phone use on the cognitive functions necessary for driving. Many of the experimental studies have correlated how cell phone use, including hands-free devices, while driving interferes with or degrades various aspects of driving. Because of the quantity of experimental and behavioral studies, only representative research is reviewed in the following four categories: (1) Field-of-View Studies; (2) Brain Research Studies; (3) Simulator Studies; and (4) Benchmark Impairment Studies. 2.2.1 Field of View Studies In 2003, Strayer’s reseach group at the University of Utah found that drivers who use cell phones are less able to process visual information. Based on the observations of participants in a simulator, the study was able to conclude that drivers conversing on cell phones increase their risk of collisions. The researchers attributed the increase in collision risk to a theory called â€Å"Inattention Blindness†. Inattention Blindness is summarized to be, â€Å"Even when participants [drivers] are directing their gaze at objects in the driving environment, they may fail to ‘see’ them because attention is directed elsewhere.† The study also found that the use of hands-free and hand-held cell phones equally impair the driver’s ability to see objects. The study found that â€Å"the disruptive effects of cell phone conversations on driving are due in a large part to the diversion of attention from driving to the phone conversation.† This diversion of attention also affects the driver’s ability to react to sudden event placing pedestrians and others at increased risk for injury (Strayer, 2003). In 2005, researchers from the Japanese Automobile Research Institute further examined the findings from the University of Utah report. The authors of this report agreed with the conclusions of the earlier report, but felt that a more direct assessment of the visual attention needed to be done to identify the exact amount of diversion from what the driver is looking at to the cell phone conversation. The authors conducted experiments with drivers on a simulator using the medically known physiological response â€Å"Binocular Fusion†. The results of this study show that, â€Å"engaging in hands-free phone conversation interferes with visual information processing. The increment of binocular gaze dissociation by conversing on a phone indicates that the driver’s attention is diverted from the external scenery to the conversation.† The purpose of the report was not necessarily to prove that speaking on a cell phone increases crash risk, but this relationship is inferred by the authors (Uchida, 2005). Figure 2 is extracted from Wood’s field-of-view study in 2006 that obtained similar results as the studies mentioned above. It demonstrates the number of errors drivers made while listening and responding to questions went up dramatically when compared against no distractions. 2.2.2 Brain Research Studies A 2005 Study by GM Corp., Wayne State University Medical School, and Henry Ford Hospital set a foundation for understanding how cell phone use by a driver influences the brain function. This study used Functional Magnetic Resonance Imaging (Æ’MRI) and Magnetoencephalography (MEG) to locate essential brain activated structures and their corresponding dynamics. As discussed above, field-of-view studies generally depend on behavior observations to determine if the mind is focused on the road and thus fail to completely reflect what the brain may actually be doing. The authors suggest that there are situations where behavioral indicators will show that the mind is on the road, but in reality, it is not. With this understanding, the authors set out to uncover the exact neural mechanisms that are associated with distracted behaviors while driving. Putting participants in a simulator and monitoring their brain function, the authors were able to identify the major brain pathways involved in driving and distracted driving. This study set a foundation for determining and measuring how the brain reacts to distracted driving (Young, 2005). In 2007, researchers at Carnegie Mellon University conducted a study furthering the previous study by using Functional Magnetic Resonance Imaging (Æ’MRI) to investigate the impact of concurrent auditory language comprehension on the brain activity when simultaneously exposed to a simulated driving experience. Participants operated a driving simulator, either undisturbed or while listening to statements they had to identify as true or false. This auditory language comprehension was designed to mimic talking on a cell phone. The participant’s brain activity was monitored during the simulations and was compared against the Æ’MRI scans of the undisturbed driver’s brain. The authors found that when participants experienced the dual-task condition, mental resources were taken away from areas of the brain that deal with driving tasks (see Figure 3). This occurred even though the areas of the brain that deal with driving tasks and auditory comprehension are different. The authors were able to make two conclusion based on their experimental data: (1) mental resources are diverted from driving tasks to 5 auditory comprehension regardless of other physical tasks; and (2) the deterioration of driving performance occurs because of a competition of mental resources in the brain between driving tasks and auditory comprehension (Just, 2008).

The researchers were able to conclude that cellular phone conversations while driving caused the subjects to react slower to stimuli and perform tasks with considerably reduced precision. Specifically, while engaged in cell phone conversations the subjects were twice as likely to miss simulated traffic signals compared to when they were not distracted. These results were also qualified by showing that talking on a cell phone was more dangerous than when the driver was subjected to common in-vehicle distractions, such as the radio and books-on-tape. The researchers also wanted to determine if the reason the subjects missed the traffic signals was because they did not see them or because they were slow to respond to them. To determine this, the researchers examined the memory of the subjects after normal driving as well as distracted driving. The results indicated clear memory impairment after having been engaged in cell phone conversations. The researchers were able to conclude that active participation in a cell phone conversation while driving disrupted driving performance by diverting attention from driving tasks to a cognitive process. In a 2002 observational study by the Insurance Corporation of British Columbia, researchers used a complex method of identifying specific cell phone users and non-users through in-field observations, and linking these people with their driving records. This method presents some obvious limitations or uncertainty about the user classification; however, the results corresponded well with other identifying methods. The driving records of the cell phone users had higher counts of moving violation citations over the previous four years, to include speeding, alcohol, failure to use seat belts, aggressive driving violations, and non-moving violations. Although the correlation between these violations and use of a cell phone is not scientifically proven by this study, it does likely reflect a difference in lifestyle, attitude and personality of the typical cell phone users; indicating they are inherently riskier drivers (Wilson, 2003). These simulator studies are consistent with a self-report survey conducted by the Traffic Injury Research Foundation. The authors of this report determined that people who use cell phones while driving were more likely to have received a traffic ticket in the last year, drive after drinking, and to consume greater quantities of alcohol when they drink. Again, these behavioral indicators cannot necessarily be directly linked to cell phone use; rather, they suggest a personality type who frequently uses a cell phone while driving (Beirness, 2002). 2.2.4 Benchmark Impairment Studies Innumerable studies have been able to prove the correlation between cell phone use while driving and an increased risk of crashing when compared to normal driving. What these studies have failed to do is show a comparison to known impairment levels. There have been at least three studies that compare the cell phone driver to a drunk driver at the per-se blood-alcohol concentration limit of 0.08 wt/vol. This blood alcohol concentration has been thoroughly studied and quantified as the limit at which the average driver will become incapable of safely operating a motor vehicle. Comparing the cell phone driver to a benchmark of this caliber becomes a solid comparison and explanation to how dangerous driving while on a cell phone really is. In a 2002 study by Burns et al., the authors designed a study to compare the impairment from handsfree and hand-held phone conversations to the decline in driving performance caused by alcohol impairment. Participants were given either an alcoholic beverage or a placebo drink and placed in front of a driving simulator that represented realistic driving tasks. The quantity of alcohol was determined from the participant’s age and body mass, and was closely correlated with the legal limit of .08 mg/ml blood alcohol concentration. The results of this experiment showed a clear substantial decrease in driving performance when using a hand-held phone, in comparison to the sober condition. Driving performance under the influence of alcohol was significantly worse than normal driving, but better than driving while using a phone, leading to a conclusion that driving while talking on a phone is more impairing then driving at the legal limit of alcohol. Strayer’s research group at the University of Utah published research comparing the cell phone driver and the drunk driver in 2003, and a revised report in 2006. The purpose of their research was to provide a direct comparison of the driving performance of a cell phone driver and an alcohol impaired driver in a controlled laboratory setting. These researchers used participants who were casual drinkers and compared their own sober driving, cell phone driving, and alcohol-impaired driving to themselves. This method of control seems to be more accurate than the previous studies’ process of comparing the same situations in different subjects. The researchers were able to conclude that both the intoxicated driver and the cell phone drivers’ driving profiles were different from the sober base-line. Cell phone drivers exhibited a delay in their response to events, had longer following distances, took longer to recover lost speed following braking, and were involved in more traffic accidents. Drivers in the intoxicated condition exhibited a more aggressive driving profile by following closer to the vehicle in front of them and braking harder. The researchers suggest the data indicates impairment or risk from cell phone use is as great as that of the intoxicated driver, but in different ways. The authors also noted that driving impairments associated with hands-free devices and hand-held devices were not significantly different, indicating that the impairment comes from a diversion of attention from the processing of normal driving tasks. 2.3 Real-World Studies Several real-world studies have been conducted and are being conducted to further validate the epidemiological and experimental studies. Our review indicates that the majority of these studies are funded in part by insurance companies or makers of driving performance enhancers. The most commonly cited real-world study involved 100 cars and 42,000 hours of driving time monitored by in-vehicle cameras and sensors over a one-year period. The study was conducted by the Virginia Tech Transportation Institute in 2006, and concluded that, â€Å"secondary task distractions† were the prime factor in collisions. The single biggest distraction leading to collisions was cell phone conversations, dialing, and sending text messages. The Virginia Tech Transportation Institute is conducting another study that involves 2500 drivers and will last three years (Bunkley). We have been able to identify several other current real-world studies that are underway. The studies are funded primarily by insurance companies, and we have been unable to obtain any information about them due to proprietary reasons (Olson, 2007; Robinson, 2008). 2.4 Police Accident Reports Since the studies prove the hypothesis that cell phone use while driving increases crash risk, quantitative analysis of crash causation data should reflect this. This, however, is not the case. The reasons that the real-world data does not match the experimental and epidemiological conclusions are due primarily to two factors. First, three states in 2001 and six states in 2002 provided a specific space on their uniform crash reports to indicate that the use of a cell phone had been involved in the collision. In addition, even with a space available on a police report to record cell phone involvement, the box may or may not be marked. The investigating officer has multiple responsibilities at an accident scene, including tending to injured, restoring traffic flow, completing the investigation, and issuing citations for criminal violations. Officer discretion plays a part in the completion of police reports; even if evidence of cell phone use is present, the officer may or may not indicate that cell phone use was a factor in the collision. A NHTSA study of North Carolina supports this analysis. The study concluded that the underreporting of crashes that are a result of inattention due to cell phone use is substantial. The portion of crashes that were reported to be due to inattention because of cell phone use was 1.5 percent which is significantly below the estimated value obtained in more comprehensive studies of 3050 percent (Cohen, 2003). Second, even if the collection of this data is a requirement for every state, it would likely still be inaccurate because of the public’s reluctance to report cell phone use to police. Because the risks of using cell phones while driving are becoming commonly known and more states are adopting laws to outlaw the use of cell phones while driving, the likelihood that an offender admit to using a cell phone to a police officer becomes less. In addition, a police officer’s reasonable investigation time does not allow for a comprehensive investigation of every crash to include determining the use of cell phones. This is more likely to be reserved for very serious crashes where serious injury and or loss of life were present. To help address the underreporting of crashes that are due to cell phone use, several federal agencies, national organizations, and state and local governments have worked to improve the data collection. In 2003, the national Governors’ Highway Safety Association released a revised edition of the Model Minimum Uniform Crash Criteria (MMUCC), which included changes that would help record the number of crashes associated with distracted driving. The changes, which were developed with the help of NHTSAS, the Federal Highway Administration, the Federal Motor Carrier Safety Administration, and numerous state and local agencies, define the information that should be collected at an accident scene. Included in the new criteria is that reports should include any information regarding distracted driving. The changes are designed to facilitate more accurate reporting of distracted driving, which in turn, will give policy makers and data analysts more concrete data from which to make conclusions (Sundeen, 2004). The National Transportation Safety Board (NTSB) has also taken aim at the problem of cell phone use and its underreporting. In a press release in 2006, the NTSB acknowledged that cell phone use by driver’s results in a cognitive distraction that leads to an increase in accident rates. The same press release suggested that the remaining 20 states that at the time did not have driver distraction codes on their uniform accident reports add them (National Transporation Safety Board, 2006). In 2008, the NTSB made a press release that again emphasized the dangers of cell phone use by drivers by citing research conclusion that such activity reduces driving performance. The press release also indicated that the NTSB had added cell phone restrictions by commercial drivers to its 2009 list of most wanted safety improvements (National Transportaion Safety Board, 2008). 3. Cell Phones and Teenage Driver 3.1 Teen Drivers’ Collision Statistics Teen drivers are alarmingly prevalent in the collision statistics. In 2005, 4,544 teens ages 16 to 19 died of injuries sustained in motor vehicle crashes. In the same year, almost 400,000 motor vehicle occupants in this age group were hospitalized from injuries sustained in automobile crashes. Overall in 2005, teenagers accounted for 7 percent of the driving population, but they account for 14 percent of all fatalities. Young people ages 15-24 represent 14 percent of the U.S. population, but account for 30 percent of the motor vehicle injuries. The most concerning age group is the 16-19 year olds. Drivers in this age group are three times more likely to be killed in an automobile crash than people 25-64 years old (Lynch). As shown in Figure 4, crash risk is especially high during the first 6 months of unsupervised licensure (Lee, 2007). Understanding exactly why young drivers are so overly represented in the crash statistics is difficult to isolate, especially while the interactions between young drivers and new technology remains mostly unexplored. Even so, it is safe to conclude from the research that new drivers have difficulty with driving because of inexperience, risk-taking behavior, immaturity, and risk exposure (Lynch). Driving is a divided attention task requiring the driver to multi-task, which is a skill that one improves with experience. This is demonstrated also by figure four in the difference between the novice and learners (supervised) crash rates. The difference in crash rate is probably due to the restriction of exposure to risky situations and aid that is provided from the adult passenger assisting in much of the multi-tasking requirements. Figure 4 Crash rates for drivers under the supervision of an adult and during the first months of independent driving. (Source: Lee, 2007) A study by the Brain Trust Alliance published in 2006 suggests a possible explanation for why young drivers are overrepresented in crashes. The researchers found that the human brain continues to develop well past childhood into early adulthood, reaching maturity at around age 25 (see Figure 5). Different parts of the brain fully develop at different times. Specifically, the prefrontal cortex and parietal lobe are areas of the brain that are still developing through adolescence and the teen years. The prefrontal cortex controls planning, working memory, organization, risk management, self restraint and emotional control. The parietal lobe controls spatial perception and vision which gives the ability to interpret location, speed and distance. The researchers concluded that understanding the brain development is valuable in understanding why young drivers are at risk and the limitations that should be placed on them to reduce the risk. Specifically, the researchers suggest that the time young drivers are under supervised driving needs to be extended to give them the time they need to comprehend the risks of driving and responses for common driving situations. 3.2 Teen Driver and Cell Phone Distractions Technological distractions that tend to distract drivers, such as making phone calls, watching videos, corresponding through email, text messaging, and selecting and listening to music, are become more prolific and are alarmingly most popular with the younger drivers. All of these technologies have the ability to distract the driver; however the cell phone has attracted the most attention. Text messaging among young driver is especially alarming since 46 percent of drivers 16-17 years old admitted to driving while texting and since it not only requires cognitive resources, but it takes eyes off the road (Quain, 2007). In a 2007 study at the University of Iowa, the researchers concluded about young drivers that, â€Å"A high rate of early adoption of new technology, peer pressure, risk-taking tendencies, poor ability to detect and anticipate hazardous situations, and underdeveloped vehicle controls kills all leave young drivers particularly vulnerable to the distractions posed by the increasing variety of infotainment systems† (Lee, 2007). 3.3 Supervised Driving and Parental Involvement Young drivers, especially those recently licensed, who use cell phones compound their risks; intervention of some type is needed. A survey conducted by Allstate in February 2007 of parents of teen drivers found the following: Most parents (55 percent) said they wished they had more time to teach driving safety to their teens. Parents have the ability to influence their teen children’s’ driving in ways that no one else can. The Allstate survey shows that parents feel that teaching children how to drive safely is their responsibility and wish they had more time to teach and supervise their children. Graduated Drivers Licenses, a program to facilitate more parental involvement in a newly licensed teens driving development, are becoming more common throughout the United States. These alone, however, are proving to be insufficient to reduce the increased crash rate of young drivers. Teen driving contracts have been emphasized in many states as a way for parents to passively maintain interest in their teens’ driving behavior. A teen driving contract typically is a signed contract between parent and a teen that specifies the rules, expectations, and responsibilities for safe driving. A typical safe driving agreement covers cell phone use while driving, speeding, driving at night, carrying passengers, as well as seatbelt use. The privileges set out in the teen driving contracts are designed to be reviewed periodically and may be updated depending on how the parents feel the teen is performing (Michigan Secretary of State, 2007). 4. Legislative Attempts to Prevent Driver Cell Phone Use Although young drivers present a particularly urgent situation when it comes to cell phone use while driving, the issue is also a risky one for adult drivers. Either way, the literature and research suggest that something needs to be done to reduce the loss of life and money associated with cell phone use while driving. Numerous efforts are underway to keep drivers safe, including efforts from federal, state, and local agencies, parent groups, and schools. Governments have made various attempts through legislation to outlaw the use of cell phones while driving. This review has identified three reports on legislative efforts designed to help reduce crashes resulting from cell phone use and they are presented below: 4.1 New York State 2001 Hand-Held Cell Phone Ban In 2001, New York became the first state to adopt a law that bans the use of hand-held cell phone devices by all drivers. Prior to the law, the rate of drivers using cell phones was observed at 2.3 percent. Immediately after to several months after the enactment of the law, the observed cell phone use dropped by approximately 50 percent to 1.1 percent. By March of 2003, the rate of cell phone use had risen back up to 2.1 percent which almost matches that of the pre-ban rate. Between December of 2001 and January of 2003, only about two percent of the traffic citations issued in New York were for cell phone use even though a survey conducted by NHTSA of New York drivers showed that 30 percent admitted to still using their phones while driving. A possibility for the decline in effectiveness is the decline in media attention and enforcement since its inception (IIHS, 2003). 4.2 District of Columbia Distracted Driving Safety Act of 2005 In July 2005, the District of Columbia enacted the Distracted Driving Safety Act which prohibits all forms of inattentive driving that result in the unsafe operation of a motor vehicle including hand-held cell phones. Prior to the law, the rate of drivers using cell phones was observed at 6.1 percent. Shortly after the law took effect, the usage rate dropped to 3.5 percent. Interestingly, when the usage rate was measured a year after the law it had risen to four percent, but was still significantly lower than the preban rate. The introduction of this law also followed the typical pattern where a new law is introduced, compliance is at its highest and as time passes, the compliance drops off. Although the rise in usage a year after the introduction of the law was not as significant as that of the New York ban, it was still present. One possibility for this less significant return to pre-ban usage levels is the District of Columbia’s reputation for strict enforcement (McCartt, 2007). 4.3 North Carolina Under 18 Ban of Mobile Communication Devices In December 2006, North Carolina enacted a law that prohibited the use of any mobile communication device by drivers younger than 18 years old. Cell phone usage was observed at high schools prior to the law and five months after the law took effect. The cell phone usage prior to the law was observed at 11 percent. Cell phone usage five months after the law took effect was observed at 11.8 percent. As a control, cell phone usage in the adjacent state of South Carolina was observed over the same period of time and cell phone use there was steady at 13 percent over the observation time. Researchers conducted interviews of teen drivers in which 50 percent of the surveyed teens reported using their cell phones (post-ban) if they had driven the day prior to the survey. The conclusion of the researchers was that the cell phone law had little effect on teenage drivers’ use of cell phones (Foss, 2008). 5. Distance-Based Insurance Polices Keeping drivers safe behind the wheel is becoming an ever increasing priority as evidenced by the many new and innovative approaches to the problem. Solutions are being sought and in some cases found in areas of science, engineering, biomechanics, state-of-the-art safety designs, etc. The following review is based on a relatively new insurance concept called distance-based insurance. Vehicle insurance is typically based on a lump sum pricing method which translates to a fixed cost for each consumer regardless of how many miles a vehicle is driven. A lump-sum insurance policy will result in the same premium across a similar demographic, assuming that other aspects such as age, gender, location, driving records, etc. are the same. Consumers will not see any reduction in price if they reduce their yearly mileage which results in lower risk. Since the risk of collision and other policy claim related losses are dependent on how many miles the vehicle is driven, it seems unfair to apply a lump-sum pricing scheme to such a complex situation (Bordoff, 2008). In a paper written by Litman (1997) he makes a profound analogy of this situation to the sale of gasoline. If gasoline was sold by the car-year, vehicle owners would be required to make one lump-sum payment at the beginning of the year. This payment would allow the owner to fill the vehicle up with gasoline unlimited times throughout the year. Prices would be based on the average consumers’ use of gasoline in his/her demographic. Litman suggests that this unlimited distribution of gasoline would perpetuate an increase in fuel usage resulting in more miles driven, overall vehicle costs, congestion, pollution and increased accident risk. Consumers who use less fuel than the average would find the system wholly unfair and unaffordable and would not use it. Consumers who used more than the average would be in favor of the system because of the benefits it offers them. This system is obviously unreasonable, and anecdotally explains the limitations of our current lump-sum insurance system. In response to this problem, a new distance-based insurance pricing method has been suggested and is being implemented in some places. Distance based insurance policies are variable and are based on the vehicle-miles driven instead of the current practice of lump-sum policies. These policies are designed to better reflect the risk of consumers, since claims are generally proportional to miles driven (Bordoff, 2008). Figure 6 represents the average 2003 distribution of expenditures for ownership of an automobile in the United States. The percentage paid in insurance costs is 21 percent, a significant 13 amount. The benefits of distance-based insurance policies are many, but most importantly is that they more accurately reflect the customers’ mileage-based risk and give many consumers an opportunity to proportionally reduce their insurance rates. Figure 6 Average 2003 Distribution of Expenditures for Automobile Ownership in The United States. (Litman, 1997) Similar to how distance-based insurance pricing has revolutionized the way insurance premiums are being evaluated, safety-based driving systems can revolutionize how driving habits are reflected in insurance premiums. For example, cell phone use while driving increased the risk of collision. If a driver were to voluntarily participate in a program that restricted his/her cell phone use while driving, thereby reducing his/her risk of collision, that behavior could be rewarded by a lower insurance premium. This same methodology could be applied to any risky driving practice (i.e. speeding, teen driving at night, etc.) as reported to an insurance company through reliable technological methods. This, much like distance-based policies, would more accurately reflect the consumers’ safety risk and could result in lower insurance rates. Those who choose not to participate in the program would have to assume the average risk and associated premiums. This program would be a huge incentive for people to participate and subsequently drive safely. 6. Technological Methods for Improving Driving Safety 6.1. Active Safety Features through Vehicle-to-Vehicle and Vehicle-to-Infrastructure Comm. To help avoid car accidents and minimize harmful effects of accidents, many automotive manufacturers aim to provide active safety features such as: forward-looking speed radar, autopilot systems, lane departure warnings, integration of video cameras, collision alerts, situational awareness systems, active headlights, and vehicle-to-vehicle communications to name a few. The radar-based system can be used to help avoid or mitigate the effect of front-end collisions. A number of systems focus on how to utilize wireless vehicle-to-infrastructure communications to provide early warnings to drivers about potential hazards at intersections, where 40 percent of all traffic accidents and 20 percent of crash-related fatalities occur. Specific technologies designed to mitigate the use of cell phones by drivers are generally marketed toward the young driver because that is where the largest concern for safety is, as well as where the most potential improvements can be made. It is also the primary market because often these technologies require voluntary involvement where parents are more likely to involve their children than themselves. These devices are, relatively speaking, in their infancy. Many devices on the market seem to individually employ a portion of what is needed to be a complete and effective system, but each has its limitations. 6.2. GPS-based Driving Monitoring System Examples of a technologies used to monitor teens and provide a possible solution for talking while driving are the wide variety of Global Positioning System (GPS)-based monitoring systems. These systems use the GNSS (Global Navigation Satellite System) network to log the vehicle’s location and speed at regular intervals and allow downloading of the data for further analysis. Some advanced monitoring programs provide over-speed alerts and/or send data to a central computer or system through a wireless communication network for tracking teen drivers in real-time. It should be remarked that, in addition to the use of teen driver tracking, these kinds of GPS tracking systems have been successfully used for commercial fleet tracking and network-wide traffic monitoring. Similarly, the windshield camera produced by DriveCam Inc. can record the driving behavior and transmit digital images to a central data server for further analysis. The above-mentioned (passive monitoring) systems, however, are not seamlessly integrated with cell phones, so none of them can actively prevent the use of cell phones even when the vehicle is in motion. They provide only an opportunity for the monitor to give post-violation advice and instruction to the teens, when it might be too late. 6.3. Cell Phone Based Context Identification Currently, mobile phone usage is no longer limited to making and receiving calls, both GPS and accelerometer sensors have been widely supported in the next generation of mobile phones. For example, both GPS and accelerometer sensors have been installed in iPhone 3G smart phones from Apple Inc., and 50 percent of Nokia mobile phones shipped in 2009 will be GPS-enabled. A number of studies aim to utilize embedded sensors in the next generation of mobile phones, specifically GPS and accelerometer sensors to discover and take advantage of contextual information such as user location, time of day, as well as the type of activity the user is involved in, such as walking, driving, or standing still. This contextual information can be used to alter the phone’s status creating a â€Å"smart† phone that is safer and/or more user friendly. Chen and Kotz (2000) provided a comprehensive survey on context-aware mobile computing research. They suggest that although context-awareness is a widely researched topic, there are still areas that could be further explored. The authors specifically highlight the need to further develop the awareness, communication, and use of context-based computing as having the most potential to benefit society. The application of contextual information to cell phones is critically important because it determines what the user is doing, and thereby when to alter the phone status. SenSay is one recent application (Siewiorek et al., 2003) that integrates contextual information with cell phone use. Combining a cell phone with sensory data, user information, and user history, the researchers were able to provide a context aware phone that improves its overall usability. For example, the phone is able to change ringer volume and vibration, and further provide dynamic phone alerts and call handling depending on the users’ activity. The real-world application of this device is limited because of peripherally needed devices, but the integration of this type of context sensing devices within phones holds great potentials. In a GSM or 3G networks, triangulation among two or more cellular towers, signal strength fluctuations, and changes to the current serving cell phone towers can be also used to estimate the context of cell phone users (e.g. study by Anderson and Muller in 2006). The result of context identification, including the speed of moving cell phones, can be used to distinguish driving vs. walking or remaining still. This contextual information can be used to prevent risky driving behaviors, such as talking while driving and texting while driving. However, as shown in a study by Smith et al. (2004), the existing cell phone-based speed estimation results are less accurate when compared to GPS-based methods. These results are exaggerated during periods of congested traffic or stop-and-go traffic on arterial streets. This review was able to identify various devices for sale that are marketed toward teen drivers all with the purpose of monitoring and or reducing poor driving habits. These devices are tools which parents can use to monitor, advise, and teach their children long after the learner and graduated driving experiences have passed. Several companies currently offering some of these devices were contacted and asked if there were any studies or research that had been done showing the effectiveness of their products. The companies responded that studies have been done, but that the results were proprietary because they had been financed by insurance companies. 7. Economic Analysis of Restricting Cell Phone Use Although there is sufficient data to prove that cell phone use while driving increases the risk of crashes, complete restriction of cell phones by drivers has been controversial in part because of the benefits consumers and society receive from these calls and because the exact number of crashes caused by cell phone use are unknown. Several researchers have attempted to quantity these values by comparing the total societal cost of crashes caused by cell phone use to the benefits society receives from the same. The results of three such studies are listed below: Hahn and Tetlock (1999): A complete ban on cell phones by drivers would result in a societal loss of $23 billion annually. Redelmeier and Weinstein (1999): A complete ban on cell phones by drivers would result in a societal loss of $300,000 annually. Cohen and Graham (2003): A complete ban on cell phones by drivers would result in a net societal loss of zero. The Cohen and Graham study was a re-analysis of the Hahn and Tetlock study with updated estimates and more comprehensive analysis. Because the exact numbers of crashes that are caused by cell phone use is unknown and it is difficult to quantify the value of cell phone use in society, these variables needed to be estimated in the analyses. The variability between the three estimates shows how the results are highly dependent on the estimation of these variables. In a Study by Martin et al. (2006), researchers analyzed the impact cell phone use by drivers had on traffic flow. A â€Å"car following behavior† was identified by simulated driving for both the non cell phone user and the cell phone user. The researchers then used these â€Å"car following behavior† models and through simulation and microscopic traffic modeling, were able to identify the impact that cell phone users had on the traffic stream efficiency. The research found that with different traffic conditions and varying percentages of cell phone users, cell phone usage while driving had a negative impact on traffic flow when traffic volumes were moderate or high. Converting these delays into monetary units, the researchers were able to project the cost of the delays caused by cell phone users throughout the entire United States highway network as significant. 8. Findings and Recommendations Distracted driving has been a public concern ever since the beginning of the automobile. Cell phone use by drivers is widespread. Intuitively, one understands that cell phone use while driving is distracting and dangerous, and many studies have proven that instinct to be true. Experimental and behavioral studies have drawn an unambiguous conclusion that cell phone use by drivers results in a cognitive distraction leading to an increased risk of collision. Studies have also been able to quantify this risk as at least as dangerous as driving while impaired by alcohol at the legal limit of .08 mg/ml. Epidemiological examination of actual crash data compared against cell phone records provides confirmation that driving while using a cell phone increases the risk of collision. In the epidemiological studies reviewed in this paper, the increased risk of collision when using a cell phone while driving was found to be between 1.3 and 5.59 times greater than non-users. Real-world data, although scarce, has also confirmed that cell phone use while driving is the single largest driver distraction leading to collisions. Studies are mounting that show an obvious correlation between cell phone use while driving and increased crash risk. The association between cell phone use and increased risk of traffic crashes seems to be validated by epidemiological, behavior, experimental and real-world studies, but the actual number of crashes directly related to cell phone use is harder to determine. Because the exact number of crashes directly related to cell phone use is unknown, the likely financial savings to United States drivers for outlawing cell phone use while driving is also uncertain. Other important findings are listed as follows: (1) Government at all levels has tried to legislate a solution for this problem with poor results, (2) Young drivers are especially susceptible to the danger of cell phone use while driving because they are already overrepresented in the crash statistics, (3) Technology is intervening where legislation has failed to provide solutions to the problem of cell phone use while driving. To improve driving safety in general, and to prevent talking on cell phones while driving in particular, the following initiatives and innovations are critically needed. 1) Accurate reporting of cell phone involvement in collisions on police reports The underreporting of cell phone involvement in collisions on police reports, the best indicator of how many collisions are directly related to cell phone use, has proven to be significant. This is worrisome because many legislative efforts to stop the use of cell phones by drivers are based at least partly on this data. Legislative efforts in themselves have shown to be minimally effective to statistically ineffective in curbing the use of cell phones by drivers. Several government agencies have nonetheless continued seeking for some type of solution to this problem. 2) Technological solutions for accurately identifying driving mode of cell phone users A wide variety of research has been devoted to mobile phone-based context identification by GPS, triangulation, or signal strength. Despite considerable research efforts, the technology remains insufficient to properly distinguish the exact mode of cell phone uses such as driving, walking, or remaining still. Even with all the available location and movement data, it is still extremely difficult to distinguish if a cell phone user is driving a car, seating as a passenger, or riding a bus or train. Inaccurate context identification could lead to problematic disabling of the communication capability when a cell phone user is not driving a car. Additional research is still needed in the area of artificial intelligence to improve the context estimation accuracy. 3) Integrated driving monitoring system There are many products that have been designed to address the problem of cell phone use by young drivers. Some existing context based technologies are designed to passively monitor an individual’s driving by recording their movements and making them available for download at another time. Some advanced monitoring technologies allow for real-time alerts to be sent to a central computer or by text message through wireless communications. These technologies can give real-time information to parents about safety concerns, but fail to provide any way of actively preventing the dangers from happening. The need for a context based solution that also allows for active prevention of cell phone use while driving is apparent. 4) Safety-based insurance policies Distance-based insurance policies have revolutionized the way automobile insurance is evaluated. Distance-based policies are more reflective of the individual mile-based risk and result in more fitting premiums. As distance-based insurance policies have changed how we think about insurance, so can safety-based insurance policies. If a driving safety profile could be determined for an individual consumer, insurance rates could be tailored to better reflect the individuals collision risk. This method could help further reflect a driver’s risk and in many cases lower the insurance premiums or be an incentive for aggressive or inexperienced drivers to drive safely. 5) Cost-effective car safety features Automotive manufacturers are engaged in the design of safety features on vehicles, which are intended to enhance the driver’s ability to avoid collisions. Some of the state-of-the-art safety features that are being explored by the automobile manufacturers are: forward-looking speed radar, autopilot systems, lane departure warnings, integration of video cameras, collision alerts, situational awareness systems, active headlights, and vehicle-to-vehicle communications. Automotive manufacturers have the objective of creating a â€Å"smart† car through the integration of technology. The â€Å"smart† call will be designed to enhance the driver’s ability to avoid collisions, but the driver will still maintain control. These devices, although potentially very effective in reducing vehicle collisions, fail to address the problem of cell phone use by drivers. Automotive attempts at collision avoidance systems are also relatively expensive and in some cases are limited by participation and communication between vehicles. The complete restriction of cell phone use by drivers seems to be unlikely because of the lack of concrete evidence showing how many crashes are caused by cell phone use, and what the cost of such a ban would be. Short of a complete restriction, a technology that would self-impose restrictions or that could be tailored to the most dangerous demographic of young drivers becomes most probable. A technological solution that is practical, effective, context-based, cost-effective, and focused on the driver’s actions is critically needed. References Allstate Foundation. (February 2007).
