A central assumption made in Mean-Variance Analysis and the Capital Coursework
A focal supposition made in Mean-Variance Analysis and the Capital Asset Pricing Model (CAPM) is that financial specialists like to put resources into the most effective portfolios accessible - Coursework Example The idea of the effective portfolio can be surely known in the wake of returning to the first portfolio the board speculations. One such hypothesis is the renowned capital resources evaluating hypothesis (CAPM). The CAPM is a model that shows the relationship between the necessary pace of profit and the hazard for resources that are held in a portfolio that is very much expanded. As indicated by Fama and French (2004), the beginning of the capital resource valuing model is the conspicuous work of William Sharpe (1964) and John Lintner (1965). The CAPM model is extremely valuable in exercises, for example, the assurance of the companiesââ¬â¢ cost of capital and in surveying portfolio execution. A portfolio is a gathering of advantages (more than one resource) held by a financial specialist (Sharpe 1964). The hypothesis of portfolio endeavors to direct speculators on the most proficient method to cause the best mix of resources for streamline returns just as to limit the hazard related with the ventures. The regularly utilized CAPM condition is a follows: ER = Rf + (Rm â⬠Rf)î ², where Rf is the hazard free rate, ER is the normal profit for the portfolio, (for the most part signified by the financing cost on treasury charges), Rm is the normal market return for a similar period, and à ² is the beta, which gauges the connection between the portfolio execution and the market execution. At the end of the day, beta demonstrates how touchy the portfolioââ¬â¢s execution is to the varieties in the market execution. The above condition shows that a portfolioââ¬â¢s return can be communicated regarding the hazard free return, the hazard premium and the beta. In light of the condition, which is a straight, it is uncovered that the portfolio return is legitimately identified with the h azard. That is, the higher the portfolio chance, the higher the portfolioââ¬â¢s return. The CAPM hypothesis carries us to another thought of the productive portfolio. A portfolio can be proficient under

Web Usage Are Mainstream Scientific Researchers Using the Internet to its full Multimedia Potential? As an examination introduction medium, the Internet has been intended to offer incomprehensibly more to distributers than simple content access. It's astoundingly easy to fuse photos, outlines, delineations, sounds, livelinesss, motion pictures and a wide range of non-content substance into a site utilizing the present easy to understand web improvement programming. This subject, Networks and Multimedia in Science and Technology, has been intended to open its understudies' eyes to the energizing mixed media prospects accessible that can impart examine discoveries all the more accessibly, adequately and compactly than plain content. A glance through a portion of the examination introduced by numerous individuals of these understudies, discovered connected to the NAMIST CONFERENCE PAGE, clarifies that very much planned sites can make even the most possibly exhausting subjects (measurements? butterflies?) alluring and fascinating using natural structures and proper interactive media. In any case, a peruse through the site of Australia's vital government-financed Scientific association, the CSIRO AUSTRALIA page, uncovers bunches of research papers distributed solely in content just arrangement. The http://www.nobel.se/declaration 98/physics98.html official 1998 Nobel Prize honor declaration for the field of Physics incorporates a few graphs, however nothing one would not discover in a 1970's course reading. A large number of the connections from american science association www.Sigmaxi.org's science asset page, http://www.sigmaxi.org/scienceresources/scienceresources.htm, have a modest quantity of graphical substance, yet just one site I discovered, http://volcano.und.nodak.edu/ - a site devoted to fountain of liquid magma examine - utilized film documents, sounds and liveliness, and this site was recorded under diversion for kids on sigmaxi's asset list. I accept there are numerous purposes behind established researchers' obvious abhorrence for interactive media. Not a little factor could be the conceivable recognition that examination that is introduced in a garish, brilliant way is inadequate in substance, that specialists who invest a lot of energy in introduction are trading off the exploration itself. The customary introduction of research has experienced distribution in logical diaries, not famous for their consideration regarding visual intrigue, and the utilization of broad visual or interactive media help to center the peruser's consideration could be seen as deigning. Moreover, utilizing the accessible innovation, while moderately simple utilizing the present propelled, easy to use improvement programming, is in any case definitely additional tedious than the utilization of basic content. With regards to a logical report, obvious signals are unmistakably more work serious to incorporate than comparable printed clarifications much of the time. Moreover numerous specialists are new with the methods required to create them, and additionally ready to endeavor composed clarifications than commission realistic craftsmanships. A large number of the mechanically maximized destinations associated with the NaMiST Conference page occupy the crowd from the data they plan to give. This is reflected by one gathering's customer mentioning a straightforward, uncluttered and development free page. Cutting edge pages additionally take more time to download, and frequently require modules that may themselves set aside a great deal of effort to download. Furthermore, how frequently have you trusted that a huge record will download just to discover it has been some way or another ruined and is pointless? Maybe in numerous fields of logical research, such material is basically unseemly. Clarifying quantum material science investigate on any level however the most fundamental would be incredibly hard to do utilizing designs and sound. PCs and Internet

Learn about our editorial policy Kendra Cherry Medically reviewed by Medically reviewed by Steven Gans, MD on May 21, 2019 Steven Gans, MD is board-certified in psychiatry and is an active supervisor, teacher, and mentor at Massachusetts General Hospital. Learn about our Medical Review Board Steven Gans, MD Updated on February 23, 2020 Schizophrenia Overview Symptoms & Diagnosis Causes & Risk Factors Treatment Living With In Children Verywell / Chelsea Damraksa In This Article Table of Contents Expand Common Catatonic Behaviors Getting a Diagnosis Types of Treatment For Loved Ones View All Although you may have heard the term catatonic schizophrenia, this diagnosis no longer officially exists in the current Diagnostic and Statistical Manual of Mental Disorder (DSM-5).?? It was previously one of the subtypes of schizophrenia. Currently, it is used to describe someone who is diagnosed with schizophrenia who also meets the diagnostic criteria for catatonia. Catatonia or catatonic behavior is a serious psychiatric condition that has historically been associated with schizophrenia, but it can be present in a variety of psychiatric conditions, including schizoaffective disorder, bipolar disorder, and major depressive disorder.?? Catatonic behavior may also result from certain medications and medical conditions. Catatonia is marked by a significant decrease in someones reactivity to their environment. This can involve stupor, mutism, negativism or motor rigidity, and even purposeless excitement. While these symptoms can be scary and extremely debilitating, knowing more about them (and what treatments are available) can help you better manage or help a loved one do so. Common Catatonic Behaviors Someone with this condition might experience rigidity or stupor, be unable to speak, respond, or even moveâ"and this can last for hours or even days if left untreated. Catatonia can also cause a person to perform strange movements and stay in uncomfortable-looking positions without attempting to shift into more comfortable or natural ones. In addition to a lack of mobility, erratic and extreme movement is possible in catatonic behavior. For example, you might pace in a repeated pattern and make loud exclamations for no reason at all (i.e., these actions are not in response to an environmental stimulus or event).? Parrot-like repetition or echoing of words, known as echolalia, is also a common catatonic behavior. Of course, people with this disorder may also display signs of schizophrenia, including:?? HallucinationsDelusionsCognitive problemsSocial withdrawalDisorganizationPoor self-careSocial difficultiesDecreased inability to express emotions How Schizophrenia Is Diagnosed by Observing Symptoms Getting a Diagnosis There are no labs or tests to diagnose catatonic symptoms in schizophrenia. Instead, your doctor will perform a series of medical exams and psychological evaluations to assess your physical and mental health, as well as rule out other conditions. Depending on the results, your doctor might give you a magnetic resonance imaging (MRI) scan or an electroencephalogram (EEG) to check for any lesions or unusual brain wave patterns.?? A test may also be given to check for the presence of drugs and alcohol. During the psychiatric evaluation, you will be asked questions about your thoughts and behaviors. A psychiatrist will attempt to discover how long you have been experiencing the symptoms in question. If a patient is in a catatonic stupor and unable to talk, his or her family may be called in to provide information about the catatonic behavior. Misdiagnosis Unfortunately, because catatonia is characterized by motor symptoms, it is sometimes mistaken for another disorder. Catatonic symptoms like facial contortions, strange limb movements, or unusual body positions can lead to a misdiagnosis of tardive dyskinesia or other movement disorders. Similarly, Tourettes syndrome may be confused for catatonia due to some of the vocalizations that can be part of the syndrome. Types of Treatment Schizophrenia is a lifelong, chronic condition, which means youll need to take steps to stay ahead of and manage your catatonic behaviors and your schizophrenia. While theres no cure, there are treatment methods that can help you to better manage your symptoms. Find Help With the Best Online Therapy Programs Medication Benzodiazepines like Lorazepam (Ativan) are perhaps the most common approach to treatment.?? These drugs act as depressants on the central nervous system, which is why they are often used to treat anxiety. Because these drugs are fast-acting, they can often relieve catatonic symptoms quite quickly. However, they can be habit-forming when used as a long-term treatment. There is some debate around the use of antipsychotics in catatonia. In some cases, antipsychotics can worsen catatonia and are often discontinued in its acute management. However, they are generally reintroduced to treat and prevent the symptoms of schizophrenia. How Schizophrenia Is Treated Electroconvulsive Therapy (ECT) ECT, formerly known as electroshock therapy, is increasingly used to effectively treat catatonia in schizophrenia and other psychiatric conditions. Living With Schizophrenia For Loved Ones Witnessing someone you care about experience catatonic behavior with schizophrenia is certainly scary. Perhaps the best thing you can do is to stay educatedâ"about diagnosis, symptoms, and effective treatmentâ"so you can get help right away if you notice any signs of catatonia like rigidity or stupor or erratic and extreme movements. Depending on the severity and type of symptoms, you may need to step in to describe the catatonic behaviors to your loved ones doctor. Doing your best to encourage your loved one to work with his or her mental health professional and stick with the treatment plan will help ensure that schizophrenia is being well managed and controlled. And dont forget self-care, which is essential for sustaining the mental energy required to support someone with a mental illness. Try to get ample sleep, eat right, exercise, and make time for relaxation and fun in your life. A Word From Verywell Getting a proper diagnosis and complying with treatment is key to coping with catatonic behavior. While schizophrenia is a lifelong disease, catatonia can be controlled. With appropriate treatment, people suffering from catatonic symptoms as part of schizophrenia and other psychiatric conditions can find significant relief from their symptoms.

I have been a vegetarian for about four years and as I have attended college I have learned more about the state of the issue with food production and sustainability. When presented with the list of books for our independent project Omnivore s Dilemma immediately jumped at me. When Pollan stated in the introduction, ââ¬Å"Farming and food industry produces even more greenhouse gases than all forms of transportation put together; the way you eat affects the world more than anything else you do,â⬠I was hooked. Michael Pollan the author of Omnivore s Dilemma discusses and asks, ââ¬Å"what should we have for dinner?â⬠He attempts to answer one of the pressing questions of sustainability in today s society, to save money or to save the planet, and how? Pollan talks about how humans are omnivores and we have the choice to eat whatever we want, no matter the health and sustainability implications of our decisions. Pollan discusses three main food chains, industrial (corn), organic, and hunter/gatherer. He analyzes each food chain, learning eating industrial is basically eating corn, and goes into the complex issues

Essay on United States Government and Federalism - 1473 Words
Over the last two centuries the United States has grappled with the idea of federalism. While former President James Madison had a very concrete understanding of that form of governance, ââ¬Å"In the compound republic of America, the power surrendered by the people is first divided between two distinct governments, and then portion allotted to each subdivided among distinct and separate departmentsâ⬠(Madison, 1788, p. 67), the United States has never had a conclusive division of power between the state and the US Federal Governments. Instead of definitive spheres of governance as Madison envisioned, over the years the US Federal Government has played an increasingly important role in state matters. Beyond changes in the balance of power betweenâ⬠¦show more contentâ⬠¦This case established the precedent that the United States Federal Government could dictate the countries monetary policies. More importantly, during this period the supremacy of federal law over state law was established with the Nullification Crisis of 1832. The ensuing conflict established the precedent that the states did not have the right to judge the constitutionality of acts of Congress. It was not until the American Civil War and the resulting defeat of the Confederate States of America that the supremacy of the US Federal Government in legislative and economic matters was established. Between the conclusion of the American Civil War and the election of President Franklin D. Roosevelt, the United States entered a period of definitive dual federalism. During this period ââ¬Å"fundamental governmental powers were shared between the federal and state governments, with the states exercising the most important powersâ⬠(Lowi Ginsberg Shepsle Ansolabehere, 2010, p. 73). While the US Federal Government left a majority of the decision making up to the states, unlike before the Civil War, the supremacy of the Federal Government was no longer in question. Although the government did establish various national standards during this period, it did little to enforce compliance on the state level.

Examining the Encryption Threat-.com
Question: Should Encryption Technologies be restricted? Answer: Introduction The interest in the encryption originates from the background of technological know-how transforming business. Presently the rise to acquire communications has propagated on the progression of the encryption schemes to be able to protect the integrity of the data because it is been transferred electronically (Ball, Borger and Greenwald, 2013). There are a number of the security services that are involved with the encryption outside the problem of the privacy: confidentiality- that is the assurance which the events involved with the communication possess a distinctive understanding of the message; authentication- the guarantee which the parties required are who they say are. Encryption safeguards our information, specific whenever it is sitting on our computer systems and in the information facilities. This assist it whenever it is being transmitted around the World Wide Web (Ou, Chung, H.Y. and Sung, 2006). The protection of the information is important to everybody. The utilization of the encryption is most effective in case it is ubiquitous along with automatic. The two kind of the encryption that happen to be primarily used are the Https URLS on the browser along with the handset to the tower link for the mobile phone calls (Koops, 2006). The encryption needs to be allowed for everything by the delinquency, rather than a function you may switch on only when you are carrying out something you believe essential and even worth safeguarding (Koops, 2006). Encryption continues to be the most important security preserving technological innovation that is right now there in the world, one which is distinctly suited would be to protect against the bulk surveillance- this really is mainly done by the authorities to be able to manage on their populations in addition to their criminals who are searching for the susceptible victims. Through forcing both to focus on their attacks against individuals, we protect the society (Ou, Chung and Sung, 2006). It is important to n ote that just as much as encryption is important as well as crucial in protection of our data when utilized by the wrong people for instance the criminals the law enforcement officials could become incapable to prevent these people from committing crimes of extraordinary magnitude (Siegfried, Siedsma, Countryman and Hosmer, 2004). Existence of indestructible encryption could render these kinds of methods of the electronic surveillance worthless, even though the law enforcement authorities might intercept on the communication that are created by the criminals they may be not able to decipher on the encrypted messages. In this research I argue as to why the encryption should be restricted. On the first issue as to why encryption should be restricted is to enable that illegal activities are not protected by the strong encryption and that the law enforcement agencies have the access of the data that can be used to fight crime and prevent the acts of terrorism (Scarfone, Souppaya and Sexton, 2007). In some tech industry it has been observed that they are encrypting data with strong encryption such that the companies are not able to access on the information of the customer to comply with the court orders and the warrants from the courts (Ball, Borger and Greenwald, 2013). The regulation of the encryption should require a licensing where only certain firms or individuals who meet the predetermined criteria are allowed to use the encryption. This this means it would allow illegal activities are protected from these encryption and the law enforcement are able to target the individual who break the law (Siegfried, Siedsma, Countryman and Hosmer, 2004). Another issue is that through restricting of the encryption to allow the enforcement officials to regulate on the encryption for the good of the public safety through providing a back door to access the information that is encrypted in the special circumstances (Scarfone, Souppaya and Sexton, M., 2007). over the past it has been observed that criminals are using unbreakable encryption to communicate with one another which renders the methods of the surveillance to be useless, to an extent that the law enforcement officials are not able to intercept the communication that are made between the criminal as they are unable to decipher on the messages that are encrypted (Tavani and Moor, 2001). When there encryption are restricted the law officials are able to monitor on every communication that is made and as result be able to identify criminals that are conspiring to do harm and at the same time protect the public from the danger they pose through their criminal activities (Scarfone, So uppaya and Sexton, 2007). This would be a preventive measure of a criminal activity before it occurred. Another issue for the need of restricting of the encryption would be to control as well as monitor on the strong encryption. According to the policy in the US companies are not allowed to exports the products that has a strong encryption, unless there has been the recovery features, which would allow the government to have access to the encryption keys (Scarfone, Souppaya and Sexton, 2007). The purpose of this would prevent the export of product which may pose threat to the national security. It would allow the organization to secure their own intellectual property from getting into the wrong hands. On a certain level this restriction would protect the information of the company which when fell on the wrong hands could compromise on their operation and their intellectual property rights in case it is stolen by the criminals. The argument against the motion: encryption should not be restricted. First it is important to understand that encryption is intended to protect individuals data from the unwanted access, this is important to every individuals and not the selected few (Ou, Chung and Sung, 2006). Having an encryption has the ability of protecting our data as well as devices from the malicious attackers. What we should ask is that who determines what data is significant and what is not. We as the individuals should be given the opportunity when it comes to determing which of our data that deem important and worthy of being strongly encrypted (Ou, Chung and Sung, 2006). I an m of the opinion that individuals need to maintain some sort of the privacy in this age where we are being constantly tracked through the traffic cams or perhaps through the electronic footprint left on the internet. There is constant exposure of the possibility of personal data falling in the hands of the criminals. Encryption is important particularly in preserving on the individuals privacy, howeve r it should not replace our security (Siegfried, Siedsma, Countryman and Hosmer, 2004). There are limitation as to where encryption does not protect our devices from being hacked, but rather facilitates on the protection of our data which we believe to be important and necessary for our privacy to remain much intact. Conclusion There are various regulations in effect worldwide which relates to the protection of the private and the sensitive data. This can be achieved through the encryption of the data, some of which has focused on the protection of the specific information in the industry. The widespread of the use of the encryption has been a necessary consequence of the revolution of the information. With the coming of the electronic communication on the computer networks, individuals need a way of ensuring the both the conversation and transaction has remained confidential. Nonetheless, as much as these encryption are providing privacy and protection of the data there are being used by the criminals and the terrorists to prevent the authorities from intercepting on their communication. In my view the encryption should be restricted. The reason for restricting on the encryption would to enable the law enforcement to have access and intercept the communication that are made between the criminal as they are unable to decipher on the messages that are encrypted. Moreover, it would make sure that all the illegal activities are not protected by the strong encryption as well as the law enforcement agencies.

The Great Gatsby Who is Daisy Buchanan free essay sample
If you were asked to describe Daisy Buchanan right after reading The Great Gatsby, you would more than likely describe her as superficial, shallow, fake and ditzy. However, there is another part of her that she hides from everyone, even herself. Under the surface, there is a reservoir. That is her character, and it takes Jay Gatsby to stir the waters and bring the cleanest form of Daisy to the surface. At first look, Daisy is a totally flat character. She came from money and wealth, she is currently wealthy, and will always have wealth and money. She seems to be in a motionlessness state, but with a closer look, Daisy varies between being very shallow and pretty deep. Even though she does not go through enough change to be called a round character. It is easy to say that she is at a half way mark between flat and round. We will write a custom essay sample on The Great Gatsby Who is Daisy Buchanan or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page She has a rather complex personality. The reader catches little insights of her true self in a lot of instances, but none better than when she talks about her daughterââ¬â¢s birth. ââ¬Å"ââ¬â¢Iââ¬â¢m glad itââ¬â¢s a girl. And I hope sheââ¬â¢ll be a fool-thatââ¬â¢s the best thing a girl can be in this world, a beautiful little foolâ⬠(Fitzgerald, 17). This quote is a lot like Daisy herself. On the surface, it sounds ridiculous and unreal, but underneath, it is one of the deepest statements that she makes. What Daisy is really meaning is that she herself is a fool. Sheââ¬â¢s nothing but a useless little housewife following a lavishly normal routine day after day. In many stories, the fool is a character with hidden wisdom and knowledge about life. The same goes for Daisy, her child, and all the women of the era. In order to live in a manââ¬â¢s world, a woman either had to overlook gender roles completely and never marry or become so humble and innocent that no one assumed her true personality or married her right away. With the conservative definition of happiness in mind, of course every woman proffered to do the second option and so Daisy wished the dreadful happiness on to her daughter. Another part of Daisyââ¬â¢s character is her love of being chased. With that being said, maybe she represents the American Dream; the dream of something unattainable. The intriguing fact about Daisy being the unattainable dream, is that once someone has finally made themselves perfect by her standards, she still rejects them. If Daisy Buchanan is not winning the game of cat and mouse, she changes the rules. For example, when she first visits Gatsbyââ¬â¢s castle of a house, she realizes that her poor lieutenant had finally reached her level. ââ¬Å"It makes me sad because Iââ¬â¢ve never seen suchââ¬âsuch beautiful shirts beforeâ⬠(92). What Daisy actually means is that she has never seen Gatsby wearing such beautiful shirts before. By earning more money than god in a period of four years, Gatsby has almost achieved the American Dream, and therefore Daisy. She is scared to be conquered, to be caught and used as a trophy for the man who achieved the American Dream. It is this fear that keeps her with Tom, because he is so dumb that he doesnââ¬â¢t realize what she is. Like anything that is chased, Daisy must have a shelter to hide in, because if Daisy, the deepest and purest form of her, was finally ever permanently removed from the reservoir in which she hides, she would not be Daisy Buchanan, she would become a shadow or a figment of the imagination.

democratic route to modernity essays
democratic route to modernity essays Barrington Moore, Jr. in Chapter seven of his Social Origins of Dictatorship and Democracy, explores among other things, the reason for England and other countries (such as the US and France) taking the democratic route to the modern world; a route which he refers to as the bourgeois revolution. This is relatively different for each country at the inception and at various points in time, but is essentially a combination of parlimentary democracy and capitalism. Whereas in China, Russia, and Germany, preindustrial bureacratic rule has proven unfavorable to democracy, in England, on a comparative level, there was more of a balance between the crown and the nobility. Moore maintains that the concept of a relatively independent nobility has proven favorable to the growth of democracy. The bourgeois class was essential to this growth as well. Whereas in France, Russia and a large part of Germany there was a strong growth of absolutism, in England there was resistance to this ideology. The landed aristocracy began getting involved in commerce at an early date in England whereas in large areas of Europe there were still communities of self sufficiency. In England a particular type of commercial agriculture (or an appropriate form as Moore puts it) was conducive to the democratic route. It fostered a relationship of dependency between the landed upper class and the bourgeois class. In order to portray the differences with the English (or even on a smaller scale) route to democracy and the Russian route, for example, Moore examines critically all these aspects and explores the variants on a comparative level, and concludes that the English experience for these specific reasons was conducive to a democratic route to modernity. social origins of dictatorship and democracy ...

Methods for mitigating challenges encountered in the classroom Coursework
Methods for mitigating challenges encountered in the classroom - Coursework Example One observes direct instruction where the teacher calls a student to demonstrate the date to the other students. Children at this tender age tend to forget terribly and hence the teacher emphasizes on repetition. The teacher keeps on explaining and clarifying rules to multicultural students. The class employs Cooperative Learn Groups where a student learns rules via demonstration and practice from other students. Students observe the behavior of the others who already know the rules. The desks are next to one another to support discussion among students (Salvin, 2006, p. 207). The students take time before they adjust to the instructions that the teacher provides. Some students find themselves unconsciously speaking in other languages. The teacher has to make sure that they cover all the rules in different languages to ensure that all the students understand. The students learn the rules best by practice and demonstration from other students who already understand the rules (Salvin, 2006, p. 101). The multicultural students find compliance with the rules hard. When Monica tells Jeanette to get the glue out, she uses Spanish. This makes her not to understand the instructions. This pedagogical strategy is this video is effective since it mitigates the challenges that the students encounter in a classroom with English language learners. The strategy that this video employs is demonstration. The teacher encourages students to demonstrate their answers to the other students in class. It mitigates the challenges that ELL students face by demonstrating instructions. This enables students to acquire skills that are necessary in the process of learning English. The student engagement with instruction is medium. This is because students come from different multicultural backgrounds and thus making it difficult follow instruction. The teacher corrects them appropriately and encourages learning among students themselves through

Sean Connery and his screen character James Bond Essay
Sean Connery and his screen character James Bond - Essay Example I choose Sean Connery as the actor who best portrays the British as a person and institution. He has won an Academy Award and has been knighted, which tells us that he is recognised in the U.S., as well as his homeland, the U.K. He is the first actor to play the role of James Bond on film. Connery has a distinctive Scottish accent which adds to his popularity as a British actor. Although he only found fame when he started acting as James Bond in 1962 at the age of 32, Connery was admired for his good looks. His fan base has remained loyal to him throughout his James Bond film career from 1962 ââ¬â 1983. At his last unofficial Bond film, Never Say Never Again, he was older than most male movie star sex symbols but he still commanded great screen presence. Fans from all over the world were introduced to Britain, and all things British because of James Bond.Connery is a world icon in his representation of the British Secret Service agent/ In accordance with the screen image of Bond as the worldââ¬â¢s super intelligent British Intelligence Secret Service agent, the scripts were written to include locations world-wide. I have chosen to examine From Russia With Love in detail because the bulk of the setting was located within Britain, namely, its capital, London. The producers of the Bond films started with a very small budget for their initial Bond movies so this second Bond movie was filmed mainly at their home ground, Britain. ... Ian was an active serviceman during World War II. He worked in the intelligence division. He put his skills and experience to good use in writing his James Bond novels. The British world of Britain's top British fictional character had such a realistic and elaborate architecture that there have been many writers who have cashed in on reconstructing this fictional and yet realistic world in books. One such writer is Griswold. (Griswold 2006). It was because of Fleming's careful construction of his fictional world of Bond and its relative realism that made Bond so successful as a fictional character. Whenever we think of Bond, we think of the British too. The public identify the image of Bond with the image of the British. Connery came under the tutelage of British film director, Terence Young, who took great pains to teach him how to move gracefully to polish up his suave image for the Bond role. Connery, Fleming and Young are all British and they have put in great effort to present Bond as a British character worthy of praise. However, after the fifth Bond film, Sean called it quits from playing the Bond character. He said he was tired of the repetitive similar plots, the seeming lack of character development for Bond, the overwhelming violation of his privacy from the public and his fear that his career was stalemate being stereotype cast as Bond. In a way, he was so entwined with the Bond character that Connery feared he was being taken over Bond. EON Productions then hired another actor, George Lazenby, for On Her Majesty's Secret Service (1969). The continuity of the Bond character was severely disrupted when George quit even before the movie was officially released. There

A Review On The ABM System Information Technology Essay
A Review On The ABM System Information Technology Essay This paper will focus on the benefits of utilizing Activity-based management (ABM) system within the workplace. ABM is defined as: a method of identifying and evaluating activities that a business performs using activity-based costing to carry out a value chain analysis or a re-engineering initiative to improve strategic and operational decisions in an organizationà ¢Ã¢â ¬Ã ¦ Activity-based management focuses on managing activities to reduce costs and improve customer value.à [1]à In order to maintain confidentiality, for the purpose of this paper I will refer to my workplace as XYZ Inc. XYZ Inc. in this instance is a Third Party Administrator (TPA) of employee health benefits. XYZ Inc. sells and administers various insurance products and services to an array of clients throughout various industries. Introduction: Organizations implement Activity-based management (ABM) due to the fact it is believed that this will aid them in making better decisions, improve performance and earn more money on assets deployed. Regardless of ones approach or belief, each organization requires information to make decisions, set priorities, allocate resources and monitor actions taken. ABM systems exist only to meet the information requirement. The information and knowledge gained are of value and benefit only when the information is used to improve the business. This paper will illustrate: where I believe ABM would be useful at XYZ Inc.; how ABM is currently used at XYZ Inc.; lastly, the overall usefulness of ABM. Recommended Application of ABM at XYZ Inc.: ABM information has wide use and applicability in XYZ Inc. There are many uses for ABM information which range from determining product/service costs to evaluating acquisition candidates. I feel that XYZ Inc. would benefit greatly by practicing ABM within its operations. XYZ Inc. would benefit from ABM by implementing its practices: To Determine Product/Service Cost; To Improve Performance of Processes and Activities; To Cut Costs/Downsize Operations; and Various other applications such as: To manage projects, to budget and to support acquisition analysis. Current use of ABM at XYZ Inc.: Currently ABM is claimed to be used in the areas of determining product/service cost, improving the performance of processes and activities and in terms of determining the budget. However, in other vital areas such as: determining when to cut costs/downsize, managing projects and acquisition analysis, ABM practices are not present. These areas definitely require the attention of ABM in order to ensure the best and most informed decisions are made relative to these vital areas of the operation. Although XYZ Inc. collects all the data they need for costing (i.e. Number of Employees to ensure, Insurance Premium Bulk Rates, Geographic Location etcà ¢Ã¢â ¬Ã ¦), they dont use it effectively or appropriately. As XYZ Inc. sole purpose is to undercut the competition and provide the lowest possible insurance premium rates to clients in order to attain their business. This is not allowing XYZ Inc. to effectively price their products/services. XYZ Inc. also receives feedback from its clients and customers relating to problems with its services, pointing to bottleneck issues within the claims reimbursements processes. Again, XYZ Inc. does not effectively utilize the information that is being forwarded to them in terms of how to remedy the issue. Rather in information is just ignored with hopes that the issue will in some fashion correct itself. Lastly, in terms of budgeting, the information collected here is used in a more serious manner. Senior management looks closely and most of ten times solely at expenditures throughout the year; almost instantaneously issuing a corporate update outlining where cutbacks will occur in the upcoming year. Most often times Senior management only looks at the large expenditures without taking into account correlating factors or benefits that may have be attained via the expenditures. Collecting all the pertinent data and utilizing it in a productive fashion, in theory would lead to more effective and efficient operations of the organization. However, when human power and capital is spent to ascertain such data and it is not used in accordance with betterment of the organization, this in turn leads to extreme discouragement and the action of accurate record keeping seems to become more and more pointless, creating a sense of uselessness in a vicious cycle and spiral downward within the organizations efficiency and effectiveness. When data is collected, it needs to be utilized in a fashion whereby everyone involved can reap and clearly see the benefits of attaining the data and using it in an effective and efficient manner for the betterment of the organization. Usefulness of ABM in Specified Application Areas: In the areas identified earlier, I will describe how ABM would be useful within the following applications. To Determine Product/Service Cost: In this area accuracy is required for operational and strategic decisions of product mix, product pricing, product line investments and production alternatives. Most ABM implementations are directed toward product/service cost. However, managers use Activity-based costing (ABC) to determine the actual, true cost of products and services. Organizations use ABC because they believe the understanding of true product/service cost will lead to better decisions of product mix, product pricing and product sourcing. Better decisions lead to increased profits. However, knowing true product/service cost does not necessarily result in better product/service decisions. If an organization is selling all it can at a market driven sales price, there may be no opportunity to increase the selling price or changes the mix of products. In these situations, accurate product/service cost information will force the organization to look at the activities associated with making or delivering an unprofitable product/service. To effect reductions in product/service cost, activities will have to be improved; requiring the implementation of ABM system. To Improve Performance of Processes and Activities: Many organizations use ABM as a structured way to select and examine key activity work processes, which are critical to the success of the organization. Activities are defined, analyzed and assigned a cost, in order to determine an organizations current or as is situation. With an organizations current or as is situation established, activities and processes with high potential for improvement can be selected and the efforts/actions undertaken to realize the improvement opportunity. Through identifying the biggest bang for the buck, improvement can be focused. ABM is also used to monitor the result of improvement initiatives. Through reporting cost and performance of processes and activities, people and teams responsible for improvement have a scorecard to judge the result of effort. The ABM system is used to provide the feedback necessary to sustain improvement initiatives. To Cut Cost/Downsize: Some organizations use ABM to cut cost, downsize, or restructure operations. This is the unfavourable side of ABM. In all actuality, ABM is an effective tool for cost cutting/reduction. In situations where financial returns are unacceptable to stockholders or when survival of the organization is at steak, organizations often take significant cost reduction actions. These actions typically take the form of layoffs, plant closings and idled equipment. Often taken across the board in all areas of the organization, they are rarely effective. Unless the volume of work is reduced, these cost reductions just leave the same work to be done by fewer people. Eventually, the cost creeps back into the organization. Activity-based cost reduction is focused on the activities of the organization. Cut activities, cost will follow. Other Applications: To Budget: To Support Acquisition Analysis: To ensure the future prosperity of XYZ Inc. ABM practices should be adhered to and utilized on a going forward basis. Conclusion: A prerequisite to benefiting from ABM is the willingness to assign responsibility for effecting decisions, actions and changes necessary to deliver the desired benefit. Decisions must be made and actions must be taken. Specific responsibility has to be assigned to reduce/eliminate non-value-added activities, improve value-added activities and reduce or eliminate the associated cost drivers. The value and benefit of ABM can only be measured by the decisions, actions and improvements that result due to the fact individuals were motivated to take action, based on the knowledge and information provided. Implementers of ABM systems should be warned that all efforts to implement an ABM system will be wasted if no one uses or takes action on the information provided. The value and benefit of ABM can be difficult to quantify. The result of some decisions can be difficult to quantify, while others cannot. Expect people to want process improvements to be credited to their project or initiative versus giving the necessary credit to the ABM system which was the driver of information leading to success. ABM information drives and supports all improvement initiatives. It can be difficult to measure and quantify its role in improvement and decision making. Activity-based management measure the result of decisions and improvements, regardless of who or what initiative gets credit. While some organizations view ABM as a tool to support improvement initiatives and decision making. The dollar sign makes this information tool useful. Organizations and managers are bottom line driven, and dollars and cents are the language of business. The dollar sign inspires people to take action. The ABM information system tracks improvements and provides individuals, managers and teams with process-based cost and operating information to judge the result of their decisions and efforts.

An Investigation of Postpartum Depression Essay -- Biology Essays Rese
An Investigation of Postpartum Depression Missing Works Cited The recent Andrea Yates murder trial brought a firestorm of controversy as the issue of postpartum depression (PPD) became a debated topic throughout the country. Did Andrea truly suffer from psychosis as she drowned her five children in the bathtub or was such defense a scheme to avoid the death sentence? Prosecutors suggested the spousal-revenge theory as a motive for the killings. Could she have committed murder to get back at a possessive and domineering husband? (1). The outcome of the trial was by no means exceptional as it was a murder case, which resulted in a life sentence conviction. It did however, create awareness within the medical field and mainstream public about the historical connection between pregnancy and psychiatric illness. Unfortunately such dialogue also brought long standing misconstrued notions which must be eradicated. Mental illness has been a reality not only for Yates but for millions of women throughout the country. Depression tends to be one of the most prevalent consequences of childbearing as 50% of new mothers report slight bouts of depression, 10% have manic depression and .2% suffer from psychosis(2). Yonkers et. al, further investigated postpartum depression rates for minority women in comparison to their Caucasian counterparts. After conducting a postpartum three trial screening which included the Structured Clinical Interview, it was found that depression rates for Latino, Blacks and White racial groups was between 6.5% to 8.5% (3). Regardless of race, all groups of women were susceptible to similar rates of PPD at 3-5 weeks postpartum. Other studies have found that depressive disorders begin even before giving birth... ...s the need for changes in the current "drive thru" system of childbirth. Hospital stays have been reduced as new mothers are quickly sent home without medical resources at their disposal(8). The Andrea Yates trial was significant in that it raised awareness of mental illness under a media firestorm. It made the American public aware of the potential actions such illness can cause a person to do. Dialogue, however, is not a sufficient means in which to properly target and treat PPD. The medical establishment must ensure prevention through mental health screenings and subsequent psychiatric check-ups for new mothers. Through educational campaigns, awareness must be brought to the masses so that the stigma attached to mental illness be eradicated. Hopefully, people will seek proper treatment as there are millions suffering with depression in isolation and silence.

Newtons Laws Relating to Car Safety Devices Essay
Ever since cars were invented in the early 20th century, there have been road fatalities. Advances in car safety technology have seen a diminishing exponential curve in casualties suffered on the road. The first invention was the seatbelt, by George Cayley in the late 1900s. The next major advance was with the airbag, by John Hetrick in 1952. A patent for the design was marketed for automobiles in 1967. The combination of all safety devices located in cars contribute to the wellbeing of the driverThe idea of a seat belt is simple, but it harnesses technology that shows a lot of ingenuity. A seatbelt is designed to keep one fastened in their seat in the event of an abrupt stop. It is essentially a piece of tough fabric that goes around the user. It combats the effect of the separate inertia on ourselves, by making us a part of the car. Inertia refers to an objects tendency to maintain its state of rest or uniform motion unless acted upon by a force. Sir Isaac Newtons First Law of Moti on revolves around Inertia. When the car is in motion, inertia wants it to keep going at that speed, but there are several forces acting on it, such as friction and air resistance. The engines power compensates for this energy loss. Anything that is in the car but not attached to it has its own inertia, and this is evident when the car is accelerating, decelerating and in the event of an abrupt stop. When in uniform motion, one cannot feel the effects of the cars inertia as separate to oneself, but the separate inertia is shown when the car is stopped suddenly. In a high speed collision, each car comes to a stop rapidly. Occupants not wearing their seatbelt will continue at the original speed of the car (as per the Law of Inertia) until acted upon by a force. An unrestrained occupant will then move at a high speed until:Colliding with the car interior or other occupants, stopping faster than the car itself, most of the time over a distance of several centimetres. Crashing through the windscreen. This concentrates an amazing amount of momentum [(momentum=mass x velocity)(M=70kgx90km/h)(M=6300)] on one of the most vulnerable parts of the human body. Impulse is defined as the product of the force and the time interval over which it acts. It is equal to the change of momentum. With a seatbelt on, one will change their momentum slower and therefore spread out the force acting on them. This significantly increases the chance of survival. An occupant with a seatbelt will have the same inertia of the car, & therefore stop with it. The rate of change of the momentum of a restrained occupant is much less than that of an unrestrained person. This means that the net force on the restrained occupant will be less. As well as increasing the time interval over which the wearer comes to a stop, a properly fitted seatbelt spreads the impact force over a larger surface area of the body, in particular the pelvis & ribcage. Seatbelts are an extremely effective means of saving lives. Car accident researchers in Australia estimate that seatbelts reduce the risk of fatal injury to front-seat occupants by 45 per cent and the risk of serious injury by 50 per cent. Airbags are designed to increase the time interval during which the drivers momentum decreases during a head on collision, therefore reducing the net force on the driver, particularly from the steering wheel & dash board. It also acts to cushion our precious head during impact. An airbag consists of 3 parts which all assist in slowing the passengers forward motion:The bag made of a thin nylon fabric, which is compressed in order to fit into the steering wheel etc. The sensor The device that tells the airbag to inflate, in the event of a collision. The sensors receive information from an accelerometer built into a microchip. The inflation system Reacts with sodium azide with potassium nitrate to produce nitrogen gas. Hot blasts of nitrogen gas inflate the airbag. When an airbag is deployed:15 20 milliseconds after impact: The crashà sensors & control unit determine the severity of the collision. This decides if the airbag will be deployed or not. 25 milliseconds: The pad covering the airbag splits in strategic weak places & begins to inflate. 45 milliseconds: The airbag is fully inflated while the occupant is still moving forward. 60 milliseconds: The occupant makes contact with the airbag, which immediately begins to deflate. Up to 100 milliseconds: The occupant continues to sink into the airbag, cushioning the head & chest while deflating. Momentum is the product of mass multiplied by velocity. Unless an outside force acts on an object, it will continue to move at its present speed & direction. If loose objects in the car are not restrained, they will continue moving at the same speed as the car, even if the car is stopped in a collision. Therefore by reducing our velocity using the airbag, one will have less momentum, & therefore a greater chance of survival or serious injury. Air bags do not just cushion your body in the event of an impact, but they also spread the impact over a larger area. By doing this, the force is not all concentrated in one small area of your body. This in turn will cause the seriousness your injuries to be reduced because the force you feel is spread out. A study stated that the number of lives saved by airbags is 600 per year. It also indicate that airbags reduce fatalities by 8% when worn in conjunction with a seatbelt. Airbags also reduce the risk of dying in a frontal crash by 30 %. Wearing both a seatbelt and having an airbag fitted car deeply increases theà survival rate in the event of a crash. Crumple zones are deliberate weak spots the car engineers place in the structure of a car. Consider a head-on collision into a concrete wall. Before the crash, the car & its passengers move together at the same velocity. With a car posing a rigid body, an impact will cause both automobile & occupants to halt very quickly. This immediate stop creates a large amount of force on the passengers. [(F=ma)(F=75kg x -30km/h-2 )(F=2250N)]. By increasing the impact time, the force on the occupants is dramatically reduced, because of this cushioning effect. Newtonââ¬â¢s first law (a body will continue its state of motion unless acted upon by a non-zero net force) is another law that explains how crumple zones work in the face of an accident. As your car moves west at 60 km/h, not only is it your car that is going that fast but it is your own body that is travelling that fast also. If your car hits a solid wall and comes to a stop immediately, your body will want to continue going west at 60 km/h because of inertia. As the car strikes the wall, the front part crushes together. As the front of the car is absorbing the impact, energy from the impact is given off in the form of heat and sound. Because the front of the car acts as a cushion, it slows the time it takes for the car to come to a complete stop; this will apply less of a force on you. The graph above illustrates how force changes as time changes with the use of crumple zones. The better the crumple zone, the more effective it is in increasing the time of a collision.â⬠Collapsible steering wheels also aid in ones survival chance in the event of a collision. It reduces the risk of impaling the driver by folding away when force is acted on it. When the body is thrown forward by the effect of inertia, the steering wheel becomes less of a deadly obstacle. Luggage restraining barriers help, in the event of a crash, by stopping theà luggage that will move forward because of its own inertia. http://www.explainthatstuff.com/airbags.htmlAccessed 1/7/09http://www.k12.nf.ca/gc/Science/Physics3204/Projects2003/SlotA/ProjectA2/index1.htmAccessed 2/7/09http://www.reachoutmichigan.org/funexperiments/agesubject/lessons/newton/airbags.htmlAccessed 2/7/09http://www.glenbrook.k12.il.us/gbssci/phys/mmedia/newtlaws/cci.htmlAccessed 4/7/09http://www.scienceperspectives.com/Sir-Isaac-and-Seat-Belts.htmAccessed 4/5/09http://hyperphysics.phy-astr.gsu.edu/hbase/HFrame.htmlAccessed 4/5/09http://www.howstuffworks.com/airbag.htmAccessed 4/5/09http://midsouthrescue.org/id7.htmlAccessed 4/5/09http://www.gm.com/experience/education/9-12/technology/physics.jspAccessed 4/5/09http://www.k12.nf.ca/gc/Science/Physics3204/Projects2003/SlotA/ProjectA2/link20.htm4/5/09http://www.k12.nf.ca/gc/Science/Physics3204/Projects2003/SlotA/ProjectA2/link20.htmAccessed 4/5/09http://www.autoevolution.com/news/how-crumple-zones-work-7112.htmlAccessed 4/5/09http://auto.howstuffworks.com/crumple-zone.htmAccessed 4/5/0 9

Creative Writing: Inn From Hell It all started on a dark a stormy night just outside of the Paris city limits at about 11:00 P.M. when Doctor Bleed and his assistant checked into the old run down inn. You see the weather was so bad that they could not even make it all the way over to Spain so they had to stop. They walked in with their clothes soaked from the rainfall, when they first walked in they realized that there was nobody at the desk to wait on them so they just took it upon themselves to get a room for the night. That was their first mistake. As they walked up the creeky stairs they peered around every corner looking for an open room so they could relax in peace.

His hands turned into boxing gloves and wasting no time he jabbed Pee Wee right in the gut leaving him laying in aftershock. Now it was payback time for that purple threat to the world Barney. The doctor found Barney in the exact same place as before and doing the exact same thing as before, Acting like a fairy!
