...DIY Doctor Health information, such as symptoms and treatment, remains one of the most important subjects that internet users research online. Not only are individuals seeking signs, symptoms, and treatments for various illnesses and diseases, they now rely on health sites for information pertaining to food safety, drug safety, and pregnancy as well. In all, 80% of internet users gather health information online (WebMd News Room. WebMd Expert Blogs, 2011). Being the health fanatic that I am, I am included in that astounding statistic. Among the many different health sites, three of the well-known, most trusted sites are WebMd (www.webmd.com), Everyday Health (www.everydayhealth.com), and Mayo Clinic (www.mayoclinic.com ). Though these sites provide reliable, pertinent medical information, they all vary in some form or fashion. After spending ample amount of time on these sites, I found that while all were very informative, WebMd seemed to offer more. There is a lot to explore at WebMD, including a drug database, articles about diseases and conditions, information about clinical trials, and abundant news and commentary relating to current events in the medical world. The site also presents live chats, offers newsletters on numerous subjects, assists users with finding doctors and health insurance, and provides the means for recording your medical profile and health history. I most certainly found this site to be an ambitious one, complete with readable, accessible, and...

...To summarize, the balanced scorecard views the mission and strategy of the organization from four perspectives: • The business owners/shareholders (represented by the Financial perspective) • Customers and other stakeholders (represented by the Customer perspective) • Managers and process owners (represented by the Internal Business Processes perspective) • Employees and infrastructure capacity (represented by the Learning and Growth perspective) Within each perspective, the following elements are developed: • Strategic Objectives - what is the process that will be used to define strategic objectives and what are the strategic objectives that should be achieved using each perspective? • Measures - how will progress for each objective be measured? • Targets - what is the target value sought for each measure? • Initiatives or action plans - what will be done to facilitate the reaching of the targets? Why does all this matter? Well, the basic reason is that everything is connected to everything else, even though policies may be created by people in widely different corporate units; those connections are often full of unintended consequences. Here’s a classic example of the complications of integrating marketing strategy with human resource strategy. At one point, Proctor and Gamble had product managers who were paid based on how well their products performed. It sounded like a pretty good human resource strategy.

...* MECHANISMS FOR DEALING WITH SHAREHOLDER-MANAGER CONFLICTS * * AGENCY VERSUS CONTRACT * * FURTHER READING: Agency theory suggests that the firm can be viewed as a nexus of contracts (loosely defined) between resource holders. An agency relationship arises whenever one or more individuals, called principals, hire one or more other individuals, called agents, to perform some service and then delegate decision-making authority to the agents. The primary agency relationships in business are those (1) between stockholders and managers and (2) between debtholders and stockholders. These relationships are not necessarily harmonious; indeed, agency theory is concerned with so-called agency conflicts, or conflicts of interest between agents and principals. This has implications for, among other things, corporate governance and business ethics. When agency occurs it also tends to give rise to agency costs, which are expenses incurred in order to sustain an effective agency relationship (e.g., offering management performance bonuses to encourage managers to act in the shareholders' interests). Accordingly, agency theory has emerged as a dominant model in the financial economics literature, and is widely discussed in business ethics texts. Agency theory in a formal sense originated in the early 1970s, but the concepts behind it have a long and varied history. Among the influences are property-rights theories, organization economics, contract law, and political...

... The Doctor “Magistrate Communication Style” “Transformation” XXX TMGMT 314: Interpersonal Skills in the Workplace G. Kent Nelson, Ph.D. University of Washington – Tacoma 03 June, 2009 The Doctor Introduction The Doctor is a film that outlines the ways that doctors around the world think. It is about a doctor who finds out the hard way that there's more to medicine than skill in the operating theater in this emotional drama. The main character is Jack McKee, who is a gifted but arrogant surgeon. He cares little about the emotional welfare of his patients and is little more than a benign stranger to his wife Anne and his son Nicky. He has been suffering from a nagging cough for some time, and when he begins coughing up blood one morning, he finally allows another doctor to take a look at him. The doctor discovers that he has a malignant tumor in his throat that could rob him of the ability to speak, or even kill him. He now becomes a patient instead of a doctor, and learns first hand about the long stretches in the waiting room, the indignity of filling out pointless forms, and the callous attitude of the professional medical community. He also gets to know June, a terminal cancer patient whose joyous embrace of life as her time draws to a close is an inspiration to him. After recovery, Jack becomes more determined to be a caring healer and strives to be a better husband and father. But his new outlook on life turns former friends into foes, and dislike co-workers...

... patient, was treated how he initially treated his patients that he realized, compassion is such a big part of what he does on a daily basis. In the end, it is profound how he realizes that every doctor becomes a patient somewhere down the line. When he realizes that, it is no longer a boys’ game and he starts standing up for what is right, especially when he finds out his colleague, before performing surgery on a man who is now suing them, tore up a patients’ records. As for the colleague who he continually disrespected, he later became the surgeon that Dr. MacKee needed the most. When you have thirty seconds before a guy bleeds out, I would rather you cut straight and care less. Dr. MacKee is so callous towards his patients in the beginning. The initial scene, the audience witnesses where Dr. MacKee is saving a man who attempted suicide, after the surgery is completed, his associates ask if there is anything that he would like to say to the patient, his response is “when that boy wakes up, tell him ten floors minimum”. (Feldman, Glick, Ziskin, & Haines, 1991). Another interaction with a patient is with a woman who has had some kind of chest surgery and she has staples running down the middle of her chest, she tells Dr. MacKee that he husband is a good man but he is worried about what her chest will look like after it is healed and he tells her “tell your husband, you look like a playboy centerfold; you have the staples to prove it”.

...1/ ENERGY BANDS IN SOLIDS In this chapter we begin with a review of the basic atomic properties of matter leading to discrete electronic energy levels in atoms. We find that these energy levels are spread into energy bands in a crystal. This band structure allows us to distinguish between an insulator, a semiconductor, and a metal. 1-1 CHARGED PARTICLES The charge, or quantity, of negative electricity and the mass of the electron have been found to be 1.60 X 10- 19 C (coulomb) and 9.11 X 10- 31 kg, respectively. The values of many important physical constants are given in Appendix A, and a list of conversion factors and prefixes is given in Appendix B. Some idea of the number of electrons per second that represents current of the usual order of magnitude is readily possible. F'or example, since the charge per electron is 1.60 X 10- 19 C, the number of electrons per coulomb is the reciprocal of this nutnber, or approximately, 6 X 10 18 Further, since a current of 1 A (ampere) is the flow of 1 Cis, then a current of only 1 pA (1 picoampere, or 10- 12 A) represents the motion of approximately 6 million electrons per second. Yet a current of 1 pA is so small that considerable difficulty is experienced in attempting to measure it. The charge of a positive ion is an integral multiple of the charge of the electron, although it is of opposite sign. For the case of singly ionized particles, the charge is equal to that of the electron. For the case of doubly ionized particles...

...Occupational Health and Safety is an interesting and ever-changing field in our world today. An especially intriguing aspect of this profession is the wide spectrum of opportunities available. With such a versatile certification as, Occupational Health and Safety Officer, the possibilities for my future are exciting. However, I believe that before a career is even considered, one must examine his motivations. I graduated from the University of Yaoundé in 1987 with a Bachelor at Law. Soon after my graduation, I secured a job with Pecten Oil as a Lease hand. With no proper orientation, I was sent to the field and on that same day I was unconsciously rushed to a hospital for an injury incurred on site. This lasted for 08 months after which period I decided that never again should any other worker be injured for lack of safety measures on any worksite. For that reason, when I travelled over to Canada, I took the Construction Safety Officers course. I am presently enrolled as a graduate student in Occupational Health and Safety at the Columbia Southern University. One of the proudest accomplishments of my life was earning my university degree, despite the fact that my early adulthood pointed in the opposite direction, beginning with my marriage at the age of 24. Throughout the 1990s I lived as one of the "working poor," someone who slipped through the cracks of supposedly historic prosperity. By the age of 25 I was divorced and frustrated with menial, low-paying jobs: clerk...

#### The Doctor

...Anyone who has ever been through the medical system - even with the very best of treatment - will identify with this film. "The Doctor" tells the story of an aloof, self-centered heart surgeon who treats his patients like names on a list. In comparison with the film to the Six Principals of Care, the characteristics of the healthcare professionals lack the importance of these six principals which is dignity, independence, safety, communication, infection control, and privacy. Here are some examples that I gathered from the film that should have been handled a better way. A client is waiting to see the doctor for a routine check-up. As the doctor walked in to the examining room, he said hello, avoids eye contact with the client, and immediately took off the client’s gown without communicating the procedure to her. He continued to examine her numbingly and then said “You’re ok”. The client was speechless, and she accepted the doctor’s un-quality of care. There were two principals that the doctor did not provide to the client during her examination; which is dignity and communication. When the doctor walked in the examining room, he must communicate the procedure by explaining that he will be removing her gown, and there will be some therapeutic therapy of her body. By communicating this information with the client, she will feel safe, secure, and unviolated because the doctor is informing or asking for her consent. At the end of the examination the doctor should try...

...Why do you want to be a doctor? A few months ago my answer would’ve been that that’s what I’ve been told I should be ever since I could remember or I would say that ‘ I want to help people’. All doctors help people though. It was only recently I came across my true reason. “You must be the change you wish to see in the world” – Mahatma Gandhi. I am truly fascinated with human anatomy. Its complexity intrigues me and I would love to continue learning more about it. However, learning about it just on a scientific level will never be satisfactory for me. Being able to interact with people and have them put that trust into you will be an honour. “The best way to find yourself is to lose yourself in the service to others” – Mahatma Gandhi. This is my way of giving back to my country, where I can help and even save others. Through medicine I can reach out to the less privileged. It will also help me in gaining experience in understanding the complexities of diseases and be a part of curing these diseases. I feel a pull to doing medicine, like it was meant to be. So back to the question, “Why do you want to be a doctor?” This is my way of brightening someone’s day every day. I want to be the person someone can trust when they are in their greatest need and make some change in this world. I want to save lives, operate on inoperable tumors and cure diseases. A doctor has a fascinating, rewarding and challenging career. This is one challenge I’m......

.... "Next year" is tahun hadapan or tahun depan. It will make your learning much easier if you will just remember that di hadapan means "in front of" or ahead of so evidently the word hadapan in the above three sentences denote something that is going to take place in the future. "Will it rain?" is simply translated as Akan hujankah? I hope you will not need to use the next sentence during your stay in Malaysia but learn it anyway in case you have a bad experience. The sentence is Saya akan panggil polis and it means "I am going to call the police". Lesson 16 Kalau… (If…) hujan = to rain, is also a noun datang = to come (pergi = to go) Kalau hujan dia tidak akan datang. If it rains he will not come. sakit = sick Kalau sakit pergi jumpa doktor. If you are sick, go and see a doctor. jumpa = to meet someone Kalau tidak faham tanyalah saya. If you don't understand ask me. faham = to understand Kalau begitu saya tidak akan pergi. If that is the case I will not go. tanya = to ask begitu = like that Kalau hujan dia tak datang (see banner) is the colloquial form of Kalau hujan dia tidak akan datang Note in passing that tak is the abbreviated form of tidak. Note that in sentences two and three above anda (you) is not necessary as it is obvious you are referring to the person whom you are addressing. The suffix lah in Kalau tidak faham tanyalah saya is meant to soften the tone so that it does not appear as a harsh order. By the way the Malay suffix "lah"......

#### Doctor Faustus

...Things aren’t always as they appear to be. This is true in John Faustus’s case in terms of his relationship with Mephistopheles and in turn the devil himself. Poor Faustus believes it is he who has called upon the demon Mephistopheles and it is his tongue that orders the servant of hell, yet he could not be any more mistaken. In reality, Faustus is the one with strings attached to him and it is Lucifer, Mephistopheles, and the Evil Angel playing the role of the puppeteer. Nevertheless, Faustus remains a student to the ideology of Christianity throughout his adventures, even amongst the bleakest of hours. God never leaves the side of John Faustus, as He relentlessly tries to bring Faustus back onto the path of righteousness. Though it was indeed Doctor Faustus that summed the evil form of Mephistopheles and bargained with the devil for control over him, it is really Faustus who is being controlled by the Evil Trinity. The Doctors free will, one of the distinguishing factors of humankind, one of Gods greatest gifts given to man, has been taken away from him. The Evil Trinity is subtly controlling his every move, poking and prodding him so that he stays on the path they have laid out for him, the path to Hell. Whenever Faustus begins to question his decision and seek repentance, either Mephistopheles distracts him with earthly pleasures or facts of hell, the Evil Angel whispers some doubt in his ear, or the Devil himself appears and threatens John that it is all over and far...

...1.2 Explain the role of plasma and haemoglobin in the transport of metabolites. Plasma is the often forgotten component of blood. White blood cells, red blood cells and platelets are essential to body function, but plasma also plays a crucial and mostly unrecognised role carrying these blood components throughout the body as the fluid in which they travel. Plasma is the largest component of the human blood, making up about fifty percent of its overall content. When isolated on its own, blood plasma is a light yellow liquid which is similar to the colour of straw. Along with water, plasma carries salts and enzymes. The primary purpose of plasma is to transport nutrients, hormones and proteins to the parts of the body that need it. Cells also deposit their waste products into the plasma, and plasma in turn helps remove this waste from the body. An example of some of these substances that are transported by plasma is metabolites. Metabolites, in turn are any chemical compounds produced as a result of metabolism. Some of the products of metabolism are carbon dioxide, amino acids, glucose, squalene and urea. Blood plasma also ushers the movement of all the elements of blood through the circulatory system. No organ in the body produces blood plasma but it is a product of several organs. As already stated, it consists of water, salts (electrolytes) and proteins (albumin and antibodies). All the water, salts and proteins are ultimately derived from the food we eat. Water and salts...
