An Essay on Baudrillard - 2221 Words

Cultural critic? Radical thinker? Critical terrorist? Nihilist? These are just a number ways French sociologist, Jean Baudrillard is described in academic literature. Famous for his well-documented theories on Post-Modernism and the media, Baudrillard presents numerous commentaries on the media’s portrayal of ‘reality’ within society. His theories are extensive and include thoughts and narratives on Marxism and the rise of ‘new’ technology, to note a few. As Richard Lane suggests, â€Å"Jean Baudrillard is not only one of the most famous writers on the subject of postmodernism, but he somehow seems to embody postmodernism itself.† (Lane, R. 2000, p.1) However, the focus of this essay is to explore and explain one of the most significant†¦show more content†¦2000, p86). Where as first and second order simulation make allowances for the existence of reality â€Å"third-order simulation †¦ generates what he calls ‘hyperrealit y – that is, a world without a real origin.† (Lane, R. 2000, p86). Through various definitions and references to social theorists, the terms of simulation and hyperreality have taken shape. In addition it has become evident that Baudrillard’s assertion that mass media are responsible for the annihilation of the real is the main focus of this discussion. However, to simply define and discuss Baudrillard’s notion of simulation and hyperreality doesn’t succeed in the task of analysis. In order to successfully analyse this specific element of Baudrillard’s many theories, it is necessary to look at the strengths and the weaknesses of the case that he presents. Touted by many as being ‘More McLuhan than McLuhan;† Baudrillard takes McLuhan’s theory of â€Å"the medium is the message† and makes it the foundation for his argument of simulation and the hyperreal. Timothy Luke agrees by saying that â€Å"McLuhan’s formula†¦is appropriately the key formula of the era of simulation.† (Luke, T. 1991, p.347). McLuhan presented a revolutionary theory that was widely accepted by, and enthralled many. To have a viable and heavily supported theory as the basis for an argument surely generates widespread interest and trust, to a certain degree. Baudrillard takes McLuhan’s theory andShow MoreRelatedEssay on Baudrillard and the Matrix1177 Words   |  5 Pages is actually a simulated reality.

A Report On Rheumatic Fever Awareness Campaign Of 2016

CAMPAIGN BACKGROUND Rheumatic Fever Awareness Campaign of 2016 is a programme by New Zealand that continues to promote awareness against sore throat caused by Group A Streptococcus which complicates to rheumatic fever. It is known that Acute Rheumatic Fever (ARF) is serious yet a preventable illness. The campaign is dedicated to reduce the incidence among children and aims to create national consciousness on the importance of early prevention, treatment and the facts about rheumatic fever that may possibly result to heart damage. In New Zealand, ARF has been significantly increasing. It is alarming as ARF is considered an evident indicator of child poverty and ill health (Sharpe, 2012). The cases of ARF doubled from 1.9 per 100 000 to 3.8 per 100 000 from 2005 to 2010 (Lowe, L., Miller, J., Sharpe, N., 2011). It is vital that the problem with ARF be addressed as its’ rates have constantly failed to decrease and thus remain as one of the highest reported third world diseases in a highly developed country such as New Zealand (Masters, 2009). According to Dr. Coleman, Minister of Health, in his media statement on ARF last May 1, 2016, he claimed that the campaign aims to decrease the cases of ARF by two thirds by June 2017. Different intervention techniques were used to pursue the objectives of the campaign such as school throat swabbing, health education, community exposure to lowly deprived areas, media advertisements and promotions. Young children susceptible to ARF and

Managerial Economics in Global Environment Samples for Students

Question: Discuss about the Managerial Economics in a Global Environment. Answer: Managerial Economics in a Global Environment As things currently are 217 looks like will be a year not so favorable to housing agents. Some surveys conducted indicate that the price of housing is no longer rising. In Britain, home ownership is still being much sought after, but borrowing has never been cheaper. Competition amongst lenders in Britain has been driven down mortgages rates to that low level. Home ownership has fallen short since 2000 and even how its at its lowest level in the past 30years and even more, there is no sing of prospective buyers who are ready to take advantage of the lucrative deals on offer.One explanation to this is that rising inflation has made people feel worse and having negative effects on the housing market. Another reason is that Brexit has made people fear to have financial commitments, but neither of the two is convincing The better off explanation that can account for the low levels of prosperity in the property market is that houses are simply expensive for the new buyers even with the mortgages rates going to as low as they are. According to the national statistics office, the average price for housing is 7.6 times the average annual salary which is more than double the figure 2 years ago. The bank wants to prevent excessive lending and has authorized lenders not to offer loans to people that are more than 4.5 times of the borrowers income In such circumstances, only one of the three things can happen: either earnings grow as the house prices remain steady or earnings remain constant while house prices fall or the house price remain high, and the income growth declines. Similarly, there are no indications of any acceleration in the wage growth this will cause the market to continue falling until the time demand drops, supply increase or banks lessens its lending conditions. Higher interest rates from banks will kill the demand for housing property .houses are being sold to foreigners who have found their money, and this is due to the decline in the value of the sterling pound Britain needs to learn from other countries that you dont need to have rising house prices or even high levels of occupation for the owner of the houses to be wealthy.Germany to be precise has done just as fine as possible though seemingly has had lower levels of price inflation and a far bigger rented section with relation to Britain. Rising home ownership affects labor mobility and creates congestion costs which generate fewer new businesses No evidence available can support the notion that buying a house means that one might lose his job some years later. Sooner if not soon a politician is going to say that Britain got the housing policy wrong. They will demand that the housing regulation is stripped off from the local authorities and be handed to them. They will accept the current taxation system in Britain and encourage housing demand. That would literary mean disrupting the current property tax system and amending it which is the reason why it is not going to take place any soon. (Elliot, 2017) Important Points from the Article Rates of income has effects on the purchasing power of the population Low mortgage rates does not necessarily increase demand for housing Owing of a house or buying of a house does not make it obvious for loss of job after some time Related Policy Issues The government throughout the local authorities has held the housing price high, and that is just the mere cause held the housing market demand. The government nevertheless came up with a policy that would overhaul the housing prices. The government through the local authorities outlaid a way through which it would ensure that people get accommodation that meets not only their preferences regarding quantity but also cost. The government through its policy is also improving the quantity and quality of properties eligible for rent both in the public and private sector. It is doing this by allowing flexibility on waiting lists helping landlord stop fraud from tenants and anti-social behavior and providing more affordable housing by restricting housing providers to charging not more than 80% of the local market price. Also by funding the local authorities to refurnish their houses, using the tenant empowerment program to support tenants in playing a role in managing their accommodation a nd encouraging investments in the private sector. This is done through schemes like loan guarantees, partnering with different entities to create homes, jobs and encourage economic growth. The government also is catering for programs like affordable homes programs and regulation of housing association economically through searching of more private investments to make housing affordable. The government has also has set up various regulatory standards that the registered housing providers both private, and public authorities must meet economic standards to ensure the value of money and rent, consumer standard to ensure tenants involvement and also empowerment. (Gov.UK, 2015) The government is trying to come up with policies that will streamline the housing industry in the Britain and just change things. However, it should also be keenly noted that the government initiatives top try and curb the low housing rates in the country did not have a real big actual impact as it was projected by the government. Through consultations with various economic expertise, Emily Cadman and Chris Giles found out that the government policies that were initiated in 2011 did not just mean that it was an automatic win for the government and that it would cause an immediate change. Most of the experts who were engaged were of the view that no great impact should be expected from the introduction of the new housing policies by the government.(Giles, 2016) Similarly, that can even be proven now as there has not been any great change in the housing sector in Britain and fact, the situation is even turning from worse to even worse where though inflation is operating at nearly the zero mark the housing market in Britain still has not got the Midas touch yet. The implementation of the policies by the government started back then in 2011, and until today there has not been any effective change in the housing market. For instance, a professor from the Imperial business school going by the name Nick Bosanquet predicted that there would not be a positive change in the housing market. He rather said that there would be experienced a negative change of about 20 to 30 percent in the demand market for housing in Britain and he attributed his predictions to the decrease in foreign demand which has become the main market for houses in Britain. He even went on further to warn against more market instability despite the government policies being put in place. Another critic by the name Diane Coyle from the University of Manchester explained that there was no touch to what the government had done about the housing industry because the current policies that the government had put in place had nothing that could substantiate supply increase. The article thought it puts into account some of the major economic policies it also does defy other theories. One of the most common policies that the article defies is the Microeconomic policy which apparently deals with policies that are targeted at the development of economic sectors and households (Elliot, 2107). The economic policy aims at ensuring the promotion of investment is achieved in the real economy through efficiency of economic institutions and productivity to raise the level of the people's living standards. The purpose of this economic policy is to identify and evaluate different applicable options that are working against the development of a given industry and at the end implement the issue. In fulfilling its actions, the policy helps create equity in the economy of a state or a country and even generate full employment among citizens of the same locality. On the defying end, the article just gives a summary of some of the policies that are working against the housing industry like the high government borrowing rates set by the banks and low-income rate due to unemployment and other small determinant policies. Instead of the article to identify such policies and give recommendations on how the policies working against the prosperity of the Britain's housing market it just keeps into account the policies but does not implement the issue arising from the identified policies(Economicdevelopment, 2016). Though the article puts into account the fiscal policy which is seen where the government changes spending and taxation by increasing interest rates and the monetary policy it does not give a clear exploration and extrapolation of the two policies. Conclusion In summary, the government of Britain needs to come up with more applicable policies that will spearhead its Housing industry and foster it into prosperity rather than maintaining the current set policies which are yet to show any results. More so it is not Britain which is suffering from this problem but some other countries are going through the same, and they can use Britain to benchmark themselves and reach their desired milestones.

By using radiantenergy, which may take the form of x rays or other types of radiation,we are able to diagnose and treat many diseases and injuries. Bothdiagnostic and therapeutic radiology involve the use of ionizing radiation( Beta, Alpha, Gamma, and x rays), with the exception of the MRI, whichuses a magnetic field rather then radiation. Radiology is classified as being eitherdiagnostic or therapeutic. Diagnostic radiology is an evaluationof the body, by means of static or dynamic images or anatomy, physiology,and alterations caused by injury or disease. A majority of thesepictures are formed by passing a low or high level of x rays through thepart of the body being examined, producing the static image on film. This image is called a radiograph or x ray picture. The image itsself may have many forms. It could be a common radiograph, such asa chest x ray; a tomograph (Greek for section), which is a radiographobtained by timing the x ray exposure to correspond with the movement ofthe x ray tube and film in opposite directions around the plane of thebody; or, finally, a computerized axial tomography (CAT or CT) scan. Which is a computer analysis of a sharply limited, thin x ray beam passedcircumferentially through an area of the body, giving the doctor of Techniciana cross-sectional image. Much like that of slicing a loaf of breadinto sections. Other images may be obtained by using ultrasoundor MRI, or by recording the activity of isotopes internally administeredand deposited in certain parts of our body. This practice is callednuclear radiology or nuclear medicine. This include such techniquesas a PET scan, or positron emission tomography, which uses patterns ofthe positron decaying to study metabolism reactions in the body. PET requiresa cyclotron as an on-site source of short-lived, positron-emitting isotopes. The isotopes are injected into the patient along with a glucose relatedcompound, and the positrons collide with the electrons in the bodyto produce photons. The photons are then tracked by a tomographicscintillation counter, and the information is processed by a computer toprovide both image and data on blood flow and metabolic processes withinbodily tissues. PET scans are particularly useful for diagnosingbrain tumor and the effects of strokes on the brain, along with variousmental illnesses. They are also used in brain research and in mapping ofbrain functions. Another form of imaging is ultrasound. Ultrasound, which uses very high frequency sound, is directed into thebody. And because the tissue interferences reflect sound, doctorsare able to produce, by use of a computer, a photograph or moving imageon a television. Ultrasound has many application uses on the body,but is more commonly used in examinations of the fetus during pregnancy,because use of radiation may affect the outcome of the baby. Someother practices for ultrasound include examination of the arteries, heart,pancreas, urinary system, ovaries, brain, and spinal cord. And becausesound travels well through fluids it is a very useful technique for diagnosingcysts( which are filled with fluid), and fluid filled structures such asthe bladder. And since sound is absorbed by air and bone it is impossibleto use a ultrasound on bones or lungs. .u81e473a3ca7095e8e770f06e8d809cbc , .u81e473a3ca7095e8e770f06e8d809cbc .postImageUrl , .u81e473a3ca7095e8e770f06e8d809cbc .centered-text-area { min-height: 80px; position: relative; } .u81e473a3ca7095e8e770f06e8d809cbc , .u81e473a3ca7095e8e770f06e8d809cbc:hover , .u81e473a3ca7095e8e770f06e8d809cbc:visited , .u81e473a3ca7095e8e770f06e8d809cbc:active { border:0!important; } .u81e473a3ca7095e8e770f06e8d809cbc .clearfix:after { content: ""; display: table; clear: both; } .u81e473a3ca7095e8e770f06e8d809cbc { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u81e473a3ca7095e8e770f06e8d809cbc:active , .u81e473a3ca7095e8e770f06e8d809cbc:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u81e473a3ca7095e8e770f06e8d809cbc .centered-text-area { width: 100%; position: relative ; } .u81e473a3ca7095e8e770f06e8d809cbc .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u81e473a3ca7095e8e770f06e8d809cbc .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u81e473a3ca7095e8e770f06e8d809cbc .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u81e473a3ca7095e8e770f06e8d809cbc:hover .ctaButton { background-color: #34495E!important; } .u81e473a3ca7095e8e770f06e8d809cbc .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u81e473a3ca7095e8e770f06e8d809cbc .u81e473a3ca7095e8e770f06e8d809cbc-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u81e473a3ca7095e8e770f06e8d809cbc:after { content: ""; display: block; clear: both; } READ: Love Is Not All EssayThe sound waves are produced by a randomoscillating crystal, and are inaudible to humans. A instrument calleda transducer is used to transmit the sound waves and receive the echoes. The transducer must be in close contact with the skin, and a jelly likesubstance is used to improve the quality of the transmission. And last of the diagnostic imaging toolsis the MRI. MRI, which stands for Magnetic Resonance Imaging. Was a technique developed in the 1950s by Felix Bloch, and is the mostversatile, powerful, and sensitive tool in use. The process of MRIwas originally called NRI (Nuclear Resonance Imaging), but was found tobe to confusing due to the fact that MRIs dont use radioactivity andionizing radiation. The MRI generates a very powerful electromagneticfield, which allows the radiologist to generate thin-section images ofany part of the body. Also it can take these images from any directionor angle, and is done without and surgical invasion. Another plusside to the MRI is The time it take to perform, where as a CAT scan maytake 30-60 min. A MRI may only take 15 minutes max. TheMRI also creates maps of biochemical compounds within a cross-sectionof the body. These maps give basic biomedical and anatomical informationthat provides new knowledge and may allow early diagnosis of many diseases. The MRI is possible in the human bodybecause our bodies are filled with small biological magnets, the mostabundant and responsive of these are the protons (in the nucleus of thehydrogen atom). The principal of the MRI, utilizes the random distributionof protons, which have basic magnetic properties. Once the patientis placed in the cylindrical magnet, the diagnosis process follows 3 steps. First, MRI creates a steady state of magnetism in the body, that is 30,000time greater then that of the earths own magnetic field. The rateof absorption in the body is measure in megahertz and gigahertz ranges. Then MRI stimulates the body with radio waves to change the steady-stateorientation of the hydrogen protons. It then Stops the radio wavesand listens to the bodies electromagnetic transmissions at the selectedfrequency. The transmitted signal is used to create images much likethose of the CAT scans, but are far more accurate and much easier to interpret. In current practice, the MRI is preferredfor diagnosing most diseases of the brain and central nervous system. And is the best diagnostic technique we know. Its images, information,and other vital information surpass that of its relatives the CAT scans,x rays, PET scans, etc. The MRI has yet another distinguishing featureit can determine between soft tissue in both normal and diseased states. The only drawback to the MRI is that is relatively expensive (~$2,000 dollarssession), but that may not be so bad when you account for all the moneyand time you save by getting treatment and diagnosis sooner. Becausethe MRI uses no radiation what-so-ever the only risk it presents is topeople who have one or more of the following: A pacemaker, neurostimulator,implanted electrodes, pumps, or electrical devices, diabetic insulin pumps,aneurysm clips, shunt, seizures, heart bypass surgery, abdominal injuries,eye prosthesis, hearing aid, dentures, middle ear prosthesis, metal mesh,wire sutures, war injuries or gunshot wounds, other known metal fragmentsin head, eye, or body, known possible pregnancy, IUDs, penile prosthesis,joint or limb replacement, fractured bones treated with metal rods, plates,pins, screws, nails, or clips, any other for of prosthesis, permanent eyeliner, wig, or make-up with metallic fragments. Many organs that may not be visible byroutine radiographic methods may become visible by ingesting, installing,injecting, or inhalation of substances. These substances are calledcontrast media, which are impenetrable by radiation. Exams involvinga contrast include the upper intestine, the colon, a arthrogram ( a injectioninto a joint), myelogram ( an injection into the spinal canal), and anangiogram ( a injection of the contrast into an artery, vein, or lymphvessel). These procedures may be observed while the they are takingplace, by fluoroscopy. Which is a movable, radiation sensitive screen. .uace83b61e079e01987eacc4e071d4519 , .uace83b61e079e01987eacc4e071d4519 .postImageUrl , .uace83b61e079e01987eacc4e071d4519 .centered-text-area { min-height: 80px; position: relative; } .uace83b61e079e01987eacc4e071d4519 , .uace83b61e079e01987eacc4e071d4519:hover , .uace83b61e079e01987eacc4e071d4519:visited , .uace83b61e079e01987eacc4e071d4519:active { border:0!important; } .uace83b61e079e01987eacc4e071d4519 .clearfix:after { content: ""; display: table; clear: both; } .uace83b61e079e01987eacc4e071d4519 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uace83b61e079e01987eacc4e071d4519:active , .uace83b61e079e01987eacc4e071d4519:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uace83b61e079e01987eacc4e071d4519 .centered-text-area { width: 100%; position: relative ; } .uace83b61e079e01987eacc4e071d4519 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uace83b61e079e01987eacc4e071d4519 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uace83b61e079e01987eacc4e071d4519 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uace83b61e079e01987eacc4e071d4519:hover .ctaButton { background-color: #34495E!important; } .uace83b61e079e01987eacc4e071d4519 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uace83b61e079e01987eacc4e071d4519 .uace83b61e079e01987eacc4e071d4519-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uace83b61e079e01987eacc4e071d4519:after { content: ""; display: block; clear: both; } READ: Martin Luther King Jr Vs Malcolm x EssayNow That I have described static imagesand the processes used to create them let me explain dynamic images andhow they are manufactured. Dynamic images, which record movementof organs or the flow of contrast material through blood vessels or spinalcanal, may be obtained be recording the image by fluoroscopy, or by recordingon to video tape or movie film (cineradiography). Both film and thevideo tape are permanent recording media. The fluoroscopic imageon the other hand isnt. However, these images can be made permanent( film spots), and can be made at any time during the examination. The use of ionizing radiation inthe assessment of a disease is similar to the use of drugs and medicationin treatment of the disease. For the simple reason that radiographicexams should only be performed for specific medical indications and onlyon the direct request of a physician or another skilled professional. And although diagnostic radiation dose levels do have a small risk potential,no current evidence shows that properly conducted diagnostic exams haveno detectable adverse effects on our bodies. Dynamic images are usedquite frequently, but not as often as static images. As I mentioned at the beginning of my report,there are 2 sections of radiology. And since I just discussed diagnosticradiology, it is time to explain a little about therapeutic radiology. Therapeutic Radiology is used in the treatment of malignant diseases withionizing radiation, either alone or with drugs. This practice branchesoff from the discovery of elements that occur naturally in the late 19thcentury. Such treatment is often described in terms of energy ofthe beam being used: superficial(less then 120 Kilovolts, orthovoltage(l20 to 1000 kV), megavoltage (Greater then 1000 kV) Superficialradiation is used in treatment of diseased skin, eye, or other parts ofthe bodies surface. Orthovoltage therapy has almost been completelyreplaced megavoltage(cobalt, linear accelerator, and betatron). Becauseit provides more efficient delivery of the intended dose to tumors deepwithin the body, sparing the skin and surrounding tissues as much as possible. Radiation therapy may be used alone asthe treatment of choice in most cases of cancer of the skin; in certainstages of cancers involving the cervix, uterus, breast, and prostate; andin some types of leukemia and lymphoma, particularly Hodgkins Disease. In such instances, radiation therapy is intended to effect a cure. But when is use with cancer-treatment drugs it may only pose as a reliefof symptoms. Radiation therapy is commonly used before and aftersurgical removal of certain tumors, in order to provide a better chanceof cure. The idea of radiation therapy is that normaltissues have a greater ability to recover from the effects of the radiationmore so then tumor and tumor cells. Thus, a radiation dose sufficientto destroy tumor cells will only temporally injure adjacent normal cell. And if the ability of normal tissue to recover from a given amount of radiationis known to be the same as or less then that of the cancer tissues, thetumor is described as being radio-resistant. Such forms of therapyare not considered an appropriate form of treatment. Well, as you can see radiology is a fieldof study that deserves our uttermost attention. For the future ofhumanity may one day totally rely on these processes.
