...When Radiation Therapy Kills CASE STUDY When new expensive medical therapies come along, promising to cure people of illness, one would think that the manufacturers, doctors, and technicians, along with the hospitals and state oversight agencies, would take extreme caution in their application and use. Often this is not the case. Contemporary radiation therapy offers a good example of society failing to anticipate and control the negative impacts of a technology powerful enough to kill people. For individuals and their families suffering through a battle with cancer, technical advancements in radiation treatment represent hope and a chance for a healthy, cancer-free life. But when these highly complex machines used to treat cancers go awry or when medical technicians and doctors fail to follow proper safety procedures, it results in suffering worse than the ailments radiation aims to cure. A litany of horror stories underscores the consequences when hospitals fail to provide safe radiation treatment to cancer patients. In many of these horror stories, poor software design, poor human-machine interfaces, and lack of proper training are root causes of the problems. The deaths of Scott Jerome-Parks and Alexandra Jn-Charles, both patients of New York City hospitals, are prime examples of radiation treatments going awry. Jerome-Parks worked in southern Manhattan near the site of the World Trade Center attacks, and suspected that the tongue cancer he developed later was related...

...When Radiation therapy Kills? Case Study Mar, 5, 2012 Submitted To: DR. Hassan M. Selim Prepared by: Group 4 Khaled Al Qubaisi Waleed Al Zaabi Ali Al Tamimi Mohamed Al Jefri Summary The new radiation therapy comes with high expected from manufacturers, doctors and technicians a long with the hospitals and state oversight agencies to cure people illness from cancers; however, what if these complex machines show the negative impact of technology and its power to kill people and steal the hope of having a healthy life! Also, in many cases, low software design, poor human – machine interfaces and lack proper training are other reasons of hospital failing to cure people who have cancer. This case study illustrates how bad radiation therapy machines are and the carelessness of technicians using these machines; both cause people death. Some examples regarding the awry of radiation treatment are the death of Scott Jerome-Parks and Jn-Charles. Jerome-Parks has tongue cancer and after getting dosages of radiation, his illness becomes worse. This is because of machine malfunctions and technicians error in using it. What has happened to him is that his brain and neck has exposed to a big amount of the radiation because of a computer error as technician uses the new multi-leaf collimator. As a result, he has deafness, near blindness, teeth falling out and difficulty in breathing and eventually he died. The other patient, Jn-Charles, was having aggressive breast cancer and...

...CASE STUDY: Linear Technology team 6 2005120111 Lim jinchul 2010150013 Lee hyeyeon 2010150028 Choi eunyoung First, Linear have paid stable dividends to shareholders since 1992. They initially set the dividend at a relatively low level. By setting the dividend at a low level, Linear could maintain a sustainable payout ratio. Also, shareholders come to expect dividends once a company starts paying it. If the company pays a dividend less than the expected dividend amount, shareholders will be frustrated. Linear’s management believes that paying dividends appeals to potential investors, who both focus on the growth of the firm and interests in steady income. They also thought that providing dividends gives a positive signal to the investors in the way that Linear have the capability to generate positive cash flows even in a tough times. Second, Linear repurchased the stocks with company’s positive cash flows. There are three reasons why the company prefers to buy back stock. First, the company can offset the dilution effects caused by exercising employee stock options. Second, it is better to return additional cash to shareholders in the form of share repurchases, because interest rate is low for the last few years. So using the cash-at-hand to buy back shares makes a better use of cash balance. Third, despite a large cash balance there were no...

...1. As an investor yourself, would you rather a firm pays you a lot of dividends or would you rather simply earn capital gains? In other words, would you rather your return for investing in a firm’s stock come from quarterly cash dividends or stock price appreciation? Why? If I had to choose dividends or stock price appreciation, I would prefer a stock repurchase. When a company buys back shares, investor`s ownership percentage rises without any tax consequences. Unlike a cash dividend, a stock repurchase gives the decision to the investor. An investor can choose to tender his shares for repurchase, accept the payment and pay the taxes. With a cash dividend, a stockholder has no choice but to accept the dividend and pay the taxes. In addition, stock repurchases offer companies more flexibility than dividends. Once a dividend is put in place, it might have a big negative if the dividends are decreased or ceased in the future. In contrast, if a company stops repurchasing shares, it is hardly noted. Moreover, companies usually initiate a share repurchase when the stock is estimated to be undervalued. A company`s management team knows its business and relative stock price very well, and it is unlikely that it would purchase its stock at a high price. 2. Given historically dividends result in higher taxes for individual investors than capital gains, why have firms still paid dividends? A company that pays dividends forms a positive image and sends good signals to the shareholders...

...A STUDY ON TRAFFIC RULES VIOLATIONS IN CHENNAI (VANDALUR AND PERANGALUTUR) Submitted By: Praveen Kumar A, MBA. INTRODUCTION Violations in traffic laws are very common in a highly populated country like India. The conditions are even worse in metro cities like Delhi, Mumbai Bangalore and Chennai. The accidents associated with these violations cause a huge loss to life and property. Same is the case in Chennai. Being a metro city and a highly populated one also, has a lot of road accidents every year. Despite this the violations in traffic laws do not reduce. A lot of people disobey the rules every day sometimes willingly and sometimes because they are forced to do so because of others. The major traffic laws in India are wearing a helmet in case of two wheelers, putting a seat belt in case of cars, driving on the right side of the road including overtaking from the right direction, over speeding in certain restricted areas, not obeying the traffics signals and stooping the car after the finish line. It is mainly because of these violations that major accidents occur. It should be recognized that the highway is a social situation, in which people are interacting. However the drivers are unknown to each other in most of the cases and the interaction between them very brief and non-recurring. The communication between them is very limited and that also through mechanical aids like lights and horns. The main objective of these laws is to minimize the confusion...

Slocum ABOUT This Book A college student challenged a senior citizen, saying it was impossible for their generation to understand his. "You grew up in a different world," the student said. "Today we have television, jet planes, space travel, nuclear energy, computers..." Taking advantage of a pause in the student's litany, the geezer said, "You're right. We didn't have those things when we were young; so we invented them! What are you doing for the next generation?"1 This book is about helping people to learn how to create their own future! It does this by taking advantage of the fact that the reader’s LEFT brain sees the LEFT side (FUN) of the book. The RIGHT brain sees the (MENTAL) side of the book. Its simply FUNdaMENTAL! This in itself is a key feature of this book: It seeks to train the brain to think by many a link. Creating things is NOT done by following a monotonous recipe... The ability to create can be learned by anyone who has a yearn to learn! But the eye must be quick to sort and pick! Embedded inside, many...

...University of Technology ABSTRACT A quest for powerful tools to support creation of innovative solutions exists in industry. Majority of development efforts aims for incremental development of products, either by means of improved performance in use or during manufacturing process. New concepts or solutions on product’s functionality and behaviour (behaviour meaning how the functionality is delivered, response) are needed to bring benefits. Generic product development theories, models and methods are applicable for new product development, as their approach is linear and founded on functional requirements and means to execute them. However, in industry the product development activities preferably start from existing product or concept with pre-determined goals rather than from scratch. Creativity techniques and multidisciplinary workgroups have been referred in literature as means for creating innovations. However, these methods lack context of technical system and are general in nature and could be used for any problem with assistance of experienced moderator and a group of individuals. These techniques and methods are not included in this study. An approach from retrospective case study is presented. It was found that the mental process of an innovator follows more problem solving theory than design theory. However, the structuring and verbalization of the problem, in which constraints and resources are considered, do not include multidisciplinary view of different technologies. A new...

...Dividend Policy at Linear Technology Firms pay dividends for a multitude of reasons, such as the ability to make use of excess cash that stockpiles when a firm lacks enough viable investment opportunities with positive NPVs. Paying dividends can also send strong signals to investors of positive future earnings while rewarding them with immediate cash returns. From the market’s perspective, merely sending statements that a company is financially healthy doesn’t hold much weight. However, when a firm undertakes the costly action of issuing cash dividends, the message the firm sends is much stronger and more believable. It shows a certain level of expected financial stability since the markets expect dividends to be paid out consistently once they have been declared. While dividends have always been a popular way of distributing money to investors there has been a strong decrease in their issuance since 1978. Back then, about two thirds of publicly traded companies in the United States paid dividends. However by 1999 this number dropped to about one fifth of firms. The main reason for the decline was that until the new tax laws in 2003 passed, top bracket taxpayers paid a capital gains rate of 20%, while being taxed at 38.6% on their dividends. Therefore, paying dividends seemed to be an inefficient use of a firm’s cash and made these stocks less attractive to wealthy investors. Instead many firms favored stock repurchases. In addition, the trend away from dividends could be...

Communication is deemed incomplete without a feedback. Communication includes verbal and nonverbal communication (such as facial expressions, body language, or gestures, visual communication such as the use of images or pictures, such as painting, photography). Communication is a vital part of personal life and is also important in business, education, and any other situations where people encounter each other (Encarta, 1998). Organizational communication is largely focused upon building relationships, or repeated interpersonal interactions, with internal organizational members and interested external publics. For organizations to be successful they must have competent communicators. This case study is an attempt to bring forth, analyze and compare different aspects of workplace communication. It focuses in communication which is considered a significant factor for an organization‘s internal and external progress. It is a study on literature, which aims to link the literature findings with a real case of a company which lacks effective organizational/workplace communication. In the end, it proposes certain strategies to be improve effective organizational...
