Pouring Postmodernism into the Computer :: Internet Technology Essays

Pouring Postmodernism into the Computer "I can't define it, but I know it when I see it," has become a standard reply to questions that are hard to answer, now serving as the definition of more than just pornography. Postmodernism seems to at times share this elusive definition. To paraphrase Lyotard, its refusal to take solace in and unified form and conventions are partly responsible for its apparently shapeless definition. Paraphrasing Sherry Turkle, computer culture realizes postmodern concepts, especially a realization of those concepts pertaining to the nature of the self (17-19). For Turkle and others, partaking in chat rooms, creating identities on the computer, and the structure of computer software itself all concretize a previously abstract set of postmodern concepts. Before summarizing segments of Turkle's Identity in the Age of the Internet, a short background on postmodern concepts of the self is helpful. Postmodern thought rejects the idea of a deeper self that can be discovered by rationally peeling away surface layers of that self. The idea that truth can be found by this process, on a personal level or in a narrative structure, is a point of contention. As Stephen Frosh says in Social Experience and the Constructed Self, "More generally, postmodernism opposes all tendencies to take refuge in any illusion of wholeness or of received wisdom†¦" (277). Thus, enlightenment-age scientific approaches to uncover knowledge fall under the "illusion of wholeness and received wisdom." Instead, postmodernism perceives the world through a large network of interconnected but meaningless things and experiences (Frosh, 282). Frosh's opinion of self and action is also revealing: "†¦gone is the differentiation between the self and its expression†¦.Meaning does not precede these practices, but is enigmatically created by them†¦" (280). This is to say that in the writing of a book for example, meaning is produced by the text. The author ceases to be a sort of creator, with a preconceived plan. The book's meaning is transitory, as readers may have several different experiences with a book, regardless of the author's intentions. Finally comes the idea of the self as a social construct. To make sense of the world around us, some have suggested that the self is created in order to give a reference point for existence. Self-construction gives our lives meaning because it allows us to make sense of what surrounds us. I am me. That house across the street is not me, neither are the people who live in that house.

Physics of a Light Bulb

Physics of a Light Bulb Catherine Bellet Lab Partners: Natalie Russell Alex Harris TA: Chad Lunceford PHY 114 TH @ 2:25pm Abstract: Ohm’s law states, via the equation V=I*R, that the voltage found across a piece of material is proportional to the current. If the temperature remains constant therefore the resistance is found to remain constant. Stefan-Boltzmann law states that when the temperature if above an average of 1000K, then the relationship of voltage and current should be found to be consistent with the formula AT4.The experimental data found in this, Physics of a Light Bulb, experiment both correlates and verifies the Stefan-Boltzmann law. The voltage and current were found to be proportional to one another, verifying Ohm’s law. In addition, the fact that radiation away from the light bulb is indeed proportional to the fourth power of temperature was observed and again verified through a linear fit graph. The percent error found between the two experimental B v alues was found to be an average 6%. This showing proving that the experiment was decently accurate.Objective: To measure the relation between voltage and current in a small flashlight bulb; to determine the temperature of the filament; to verify the Stefan-Boltzmann law of radiation. Procedure: Begin the experiment by correctly setting up the circuit. Using the DMM set, find the resistance of the cold filament of the bulb at room temperature. Open a pre-set experiment file, than connect the circuit to the bulb. Slowly increase the output signal from the power supply, as the voltage reaches 10V, immediately bring the power supply back down to zero.There should be an observed recorded data and graph in the experimental file. From the recording, highlight the resistance of the cold filament from the data which corresponds to the current ? 0. 08A. Apply a linear fit which in return will give the slope, which represents the bulb resistance. Copy and paste the recorded data into Graphica l Analysis, insert various calculated columns, in order to find the temperature of the hot filament and to test the relationship versus power and temperature. Repeat for a second set of data.Use the graphs to conclude if the Stefan-Boltzmann law is obeyed. Experimental Data: See attached graphs. Results: Resistance of Cold Filament| Experimental Bulb Resistance| % Difference| B1 from Graph1(W/K)| B2 from Graph2(W/K)| % Difference| Theoretical B (W/K)| % Error of B1| % Error of B2| 2. 5? | 2. 46? | 1. 61%| 4. 26| 3. 76| 12. 5%| 4| 6. 19%| 6. 33%| Data Analysis: Discussion: The objective of the lab, Physics of a Light Bulb, was to measure the relationship between voltage and current in a small light bulb, be able to determine the temperature of the filament. nd to verify the Stefan-Boltzmann law of radiation. After completing the lab, the relationship between both the voltage and current was found to be linear, as long as the current is below or at 0. 08 A. This correlation proves Ohm ’s law therefore current through a metal conductor is proportional to the applied voltage. Through measurement and observations of the printed graphs, the temperature of the filament of the light bulb was found to be around the value of 1300K.Using the data supplied from the new calculated columns, the verification of the Stefan-Boltzmann law of radiation was proved to hold true. The law states that when the temperature is above an average value of 1000K, then the relationship between voltage and current is consistent with the formula AT4. When analyzing the curve fit of the power versus temperature graph, it is indeed observed that the experimental value given corresponds with the theoretical function that the power radiated away from the light bulb is surely proportional to the fourth power of temperature.The percent error observed for both experimental B values, when compared to the theoretical value of 4, shows to be an average of 6%, not a large value of error present. T herefore, the overall system present in the experiment proved to be both precise and accurate. Considering the percent difference between the two experimental resistors was found to be a mere 1. 61%. The percent difference between the two experimental B values was that of a higher value, 12. 5%.This may indeed have been caused by the fact that the sectioning of data for the second B value was less accurate than that of the first B value. Conclusion: At the conclusion of the experiment, Physics of a Light Bulb, the objective was surely met. The goal was to distinguish the relationship between voltage and current, as well as finding the temperature of the filament, and also to verify the Stefan-Boltzmann law of radiation. Through experimental values, it was observed that the relationship of voltage and current is found to be linear when the current is at or below 0. 8A. The temperature of the filament was also observed to be an average of about 1300K and greater. By taking the values of the Power versus Temperature graph, and creating a new Power versus Temperature raised to the fourth graph and thus applying a linear fit, the relationship of voltage and current was found to be consistent with AT4 and verifying Stefan-Boltzmann law of radiation. Current is indeed proportional to the applied voltage.

Twilight: Movie vs Book

The Twilight saga is a fantasy book that became even more popular with the movie that came out two years after the book. Twilight is about a teenage girl that brings danger to her life by falling in love with an immortal vampire. The book is written by Stephanie Meyer who has written 3 more books to the series. Even thought that the movie â€Å"Twilight† was based on the book it had a lot of differences and there were a lot of missing parts.One of the biggest differences is that the book is written from Bella's thoughts; it is really she who narrates the situations she is in. The reader gets to be Bella in a way and you find out everything she thinks and feels about Edward. Although in the movie reflects on both Bella and Edward, by watching the movie you don’t get the same feeling as in the book. If there are some private thoughts of Bella that the viewer must know about, you get them in the context of the story; it feels almost like Bella is writing a diary.Another im portant difference is how Bella finds out that Edward is a vampire. In the book, the school they are going in is having a dance and because Bella is not really that in to dancing she and Edward decide to go to Seattle, but the don’t even go to Seattle instead Edward takes Bella to the meadow and tells her what he is and he reveals himself in the sunlight so that she can see that he is sparkling in the sunlight.In the movie they are in front of their school preparing to go to class and Edward decides to go to the nearby forest, Bella went after him and she confessed that she knows what he is, Edward was surprised and he tries to scare her by showing himself in to the sunlight so that she can see that he is sparkling. However the book and the movie have a lot of similarities as well. The family dynamics are described very well. In the book Bella’s mother Rene is very eccentric and she cares a lot about Bella, even though she does not get more than a few minutes in the mo vie, you can easily see her personality.It is the same with Bella’s father Charlie, he did not spend much time with Bella when she was little and the awkwardness between them is described well in the book and in the movie. Altogether both the book and the movie follow the same storyline. As I mentioned earlier the movie is based on the book twilight and it is hard to miss that, they have the same method and all the important characters. I would recommend to read the book first and then watching the movie because the small differences in the movie are significant as of course that depends from the viewers.

IntroductionThe phases of normal wound healing   Inflammation – a reaction to tissue damage / infection   Reconstruction – granulation tissue starts to form.   Epithelialisation – the wound becomes covered with epithelial cells.   Maturation – scar tissue starts to fade and blend in with the normal tissueCase StudyREFERENCESRelated Introduction For this tissue viability assignment the assessment and treatment of a diabetic ulcer with be discussed. Wound healing and it properties will also be mentioned in regards to holistic factors affecting the chosen patient (pt).   In accordance with the Health Professional Council (HPC) a standard of conduct, performance and ethics, a pseudonym has been used to protect the identity of the pt discussed (HPC 2008).  Ã‚   I certify that confidentiality has been maintained, for the purpose of this assignment the patient will be called Mr Sim.An ulcer is a defect effecting loss of epidermis and all or part of the dermis (Lookingbill Marks 1993).   The skin comprises of three layers, and is the largest organ in the body. The average adult has 21 square feet of skin   (2 sq m)   weighing up to 3.2 Kg (Benbow 2007). The three layers of the skin are, the Epidermis   this consists of dead skin cells which shed continuously and it protects against certain bacteria.   The epidermis also acts as a barrier to prevent evaporation and absorption of water.   The Dermal Layer consists of capillaries, sebaceous (oil) glands, sensory receptors which transmit sensations such as itch, pain and temperature, and hair follicles all held together by elastin and collagen. The Subcutaneous layer contains fat and connective tissue that houses larger blood vessels and nerves. This layer is important in the regulation of temperature of the skin itself and the body. The size of this layer varies throughout the body and from person to person (Brannon 2007). The skin is a complicated structure with many functions. If any of the structures in the skin are compromised through poor blood supply, trauma, surgery etc. a wound may develop. â€Å"A wound is a loss of continuity to the skin â€Å"states Dealey Cameron (2008) The phases of normal wound healing    Inflammation – a reaction to tissue damage / infection    Reconstruction – granulation tissue starts to form.    Epithelialisation – the wound becomes covered with epithelial cells.    Maturation – scar tissue starts to fade and blend in with the normal tissue Case Study The subject of this study is a male patient aged 69 years, for the purpose of this case study the patient will be referred to as Mr Sim.   Mr Sim attended as a new patient to the podiatry department at his local clinic complaining â€Å"something has been catching on my socks†. On examination of Mr Sim’s foot a large area of callus was observed on the plantar aspect of his right fifth toe (ball of foot under little toe) there was some brown discolouration due to extravasation (leakage of blood into the skin) indicating that there could be an ulcer under the callus. It was explained to Mr Sim that further assessment and treatment would be necessary to determine what and why the problem was occurring. The podiatry assessment tool was used to provide a holistic approach to assessment of medical history and social factors that may affect the foot health of the patient.   The tool has a systematic problem based approach to undertaking clinical assessment and a detailed history; it is similar in outlay to a Patient Orientated Medical Review (POMR).   Both the POMR and the podiatry assessment tool include a description of the presenting complaint which is an important part as it determines what the patient considers to be important and can be used to establish agreed expectations.   Both models include previous and current medical history including any operations, illnesses or injuries which is of high importance in wound healing as systemic disorders or medication can have a large impact on wound healing. Both assessment tools include a detail of any known allergies, any family traits and social factors such as smoking or drug taking.   The factors assessed in the above tools are recognised as being significant factors in wound healing. Rainey (2005) lists medication, illness, smoking, alcohol consumption and mobility as factors that affect wound healing.   In addition to the POMR the podiatry assessment tool focuses on the factors that may affect the patients foot health for example previous or current occupations, an appraisal of the patient’s footwear and assessment of patients gait, vascular assessment, condition of skin, skin colour, skin temperature as well as palpating pedal pluses. A neurological assessment using a 10 gram monofilament, which is the standard neuropathy test in primary and community care in the united kingdom since National Institute for Clinical Excellence (NICE) guidelines for the management of the diabetic foot were published in 2004 (Boulton et al 2006).   However the podiatry assessment tool does not include an assessment of the nutritional status of a patient which has been regarded as a key factor affecting wound healing (Dealey 2005, Rainey 2005), and malnutrition is a very important cause in delaying the healing process (Morrison 1992). Using the podiatry assessment tool it was found that Mr Sim was diagnosed with Type 2 diabetes nine years ago and had recently moved to the area from abroad after losing his wife of to whom he was married to for forty four years, he now lives in the same road as his nephew.   Mr Sims has good control of his diabetes taking metformin 500m mg twice daily, his recent HBA1C was 7.3 % this is regarded as tight glycaemic control (Lee et al 2006) His nutritional status adequate, he reports no strong family history of diabetes or heart disease, he occasionally has a glass of red wine.   Mr Sims also takes medication to control hypertension (high blood pressure), bendroflumethiazide and aspirin, a cholesterol tablet as a precautionary method, and painkillers and antiflammatory treatment for osteoarthritis. He also mentioned that the pain in his back was increasing, and was taking a course of antibiotics for an infected cut on his hand obtained whilst gardening.   For some time now he ha d been experiencing bouts of tingling in both his hands and feet.   He expressed that he takes good care of himself never smoked, eats well and keeps active, and he states he has â€Å"an awareness of the importance of good footwear as I was in the army†. All patients with diabetes should receive an annual foot check by a trained health care professional (NICE 2004), this includes the application of a 10g monofilament to five points on each foot, to assess the protective sensation in the feet and the extent of any sensory neuropathy. Peripheral sensory neuropathy is thought to affect 20 – 40% of the population (McIntosh et al 2004) and is a major factor in the development of diabetic foot ulceration. Both feet were tested using the 10g monofilament this resulted in 0/5 probes being detected on both feet indicating peripheral neuropathy, however the dorsalis pedis and posterior tibialis were palpable in both feet, skin colour, texture and temperature and capillary refill was 2 seconds indicating good blood supply (Dealey 2005). Baker, Murali and Fowler (2005) state that the palpation of foot pulses is not a good indicator for a good blood supply.   A Doppler gives a more accurate result when assessing vascular status it assists the diagnosis by determining the presence or absence of a compromised arterial flow in the lower limb (Dughil 2006) Jeng et al (2000) concluded that if a person cannot identify the pressure from a 10g monofilament on their skin approximately 98% of the sensory ability has been lost. When the 10g monofilament is applied to the foot it buckles at a given force of 10g, inability to feel this is a significant indication that neuropathy is present and protective pain sensation is lost (Edmonds and Foster 2000). Neuropathy presents itself in various ways; motor, sensory and autonomic nerves are affected and there is no conclusive proof as to what causes neuropathy.   Factors such as high glucose levels can cause chemical changes, harming blood vessels, which supply oxygen, to tissue.   Motor neuropathy, causes abnormal foot pressures, the structure of the foot can change, giving abnormal pressure areas. Sensory neuropathy can give reduced sensation, masking pain, allowing for callus build up, and leading to ulceration.   Autonomic neuropathy, which leads to dehydration of the skin, is commonly known as arteriovenous shunting (A.V).   Neuropathy is detected by using a 10g monofilament. This is used on high pressure areas to detect if the patient can feel pain or not. These results, however, may not always be reliable, as they rely on patient feedback, therefore clinical judgement, must always be upheld at all times. Diabetes affects the vascular supply to the foot, leading to reduce or absent pulses, causing poor tissue viability, decreasing healing time. Excess glucose and cholesterol deposits in the lumen of blood vessels, reducing the diameter, which in turn, increases heart activity causing hypertension.   Aspirin is used as a prevention, it is classed as an anti-platelet drug which reduces platelet aggregation.   Aspirin inhibits enzyme COX, which reduces platelet production of TXA2, which is a powerful vasoconstrictor. Mr Johnson* is currently taking Atenolol, hypertensive drug as well as Aspirin to reduce the chances of thrombosis or MI. It was explained in detail to Mr Sim about the complications of diabetes and how it may affect the feet, during the discussion Mr Sim became upset about the loss of his wife, â€Å"she always looked after my feet particularly because of the diabetes†.   It was important to establish a good rapour with Mr Sim, as the lesion was causing him no discomfort apart from catching on his socks.   The recent loss of his wife, his back pain and hand infection had put a lot of stress on Mr Sim.   Depression is twice as likely to occur in people with diabetes and this can have a link to fluctuating blood sugar levels.   Mr Sim is also experiencing pain from his back and is still grieving about the death of his wife and coming to terms with living alone.   Stress is recognised as a factor in delaying wound healing (Dealey 2005; Glasser et al 1999; Kiecolt-Glasser et al 1995).   Cole-king and Harding (2001) found a statistically significant relationship between anxiety and depres sion and delayed in chronic wounds.   Communicating with patients can reduce anxiety and promote the natural healing process, conversely lack of communication may impair healing (Collier 1994) It was then explained to Mr Sim extenslevily about the lesion of his foot in regards to his general health without adding to his stress levels.   Education has proven to be vital in the management of diabetes (NICE) .   It was suggested that on debridement of the callus that there could possibly be foot ulcer, with Mr Sim’s consent the callus was removed using sharp debridement an ulcer was revealed.   The ulcer measured 1cm x 1cm and probed to a depth of 5mm to tendon but not to bone, the base of the was ulcer was sloughy and yellow and appearance showed no sign of infection, sharp debridement was   used   very carefully to remove slough.   Slough in the base of an ulcer is an ideal breeding ground for bacteria which increases the risk of infection and delays healing (Rainey 2005).  Ã‚   If infection was noted healing will be delayed and may spread to surrounding tissue or bone. At the time of assessment Mr Sim’s ulcer showed no signs of infection, althou gh he was taking a course of antibiotics for the infection in the wound on his hand. Diabetic problems such as peripheral ischemia or neuropathy can mask signs of infection this was considered on assessment. The wound following sharp debridement was flat and pink, this was significant as rolled edges would indicate infection. The condition of the skin was dry and showed no signs of maceration. The use of tool to grade the ulcer can provide objectivity and help with communication between health professionals.   The tool used in this study was EPUAP European Pressure Ulcer Advisory System 1998, in this case the ulcer was caused by excess pressure   over an area affected by peripheral sensory neuropathy.   There are many wound classification systems including SAD, SINBAD and PEDIS, however the EPUAP grading system was protocol for this particular community trust.   The ulcer was classified as a grade four pressure ulcer which is described as extensive destruction tissue necrosi s, or damage to muscle, bone or supporting structure with or without full thickness loss. The choice of dressing being â€Å"Activon Honey Tulle† produced by Advancis medical the gauze is impregnated with pure Manuka honey, this was used firstly to complete the debridement autolyticly.   Secondly for the antimicrobial purposes and its aid to deslough and control odour in the wound.   Benbow (2008) states a mosit environment is essential for optimal wound healing.   Other dressings are considered also for their topical antimicrobial agents, such as Iodine and Silver.   Iodine was an option although none where available in Clinic.   Iodine is a popular choice for the use in Podiatry. Silver dressings are more expensive than the honey and also should only be used when there is clinical sighs of infection (British national Formulary: BNF, Nov 2009), so, as in Mr Sim’s case there was no signs.   The secondary dressing was a foam dressing designed to absorb and retain any wound exudate to stop the wound from becoming macerated and inhibiting wound heal ing. ‘Biatain’ was the dressing choice as this is one of the foam dressings used in the clinics.   This was needed as the Activion Tulle does not have any absorption properties.   These dressing were held in place with ‘Mefix’ an adherent tape.   Mr Sim was given instructions to keep the dressing clean and dry until his next appointment Holistically the treatment plan was to contact Mr Sim’s, G.P regarding his depression over the loss of his wife, and referral to the local diabetes centre.   A lengthy discussion was held on the importance of good footwear and changing shoes regularly, as although Mr Sim’s shoes where good shoes they were very old and the innersole had worn out penetrating to the outer sole (hole in bottom of shoe).   A total contact insole referral was made to relieve the pressure long term.   Temporally a pad was mad to deflect pressure away from the ulcer overlying the dressing in situ.   Effective reduction in pressure relief is essential to heal a diabetic foot ulcer and to prevent reoccurrence (Armstrong et al 2001).   A education booklet was supplied titled Diabetic foot Ulcer, if a patient has the knowledge and understanding of their treatment plan they are More likely to comply (Dowsett 2004). Mr Sim was as asked to return to clinic in five days as part of his dressing regime, he reported he had an appointment with the G.P the following day to discuss his depression. He had also received a letter from the diabetes centre with an appointment for the following week.   The NSF (National Service Framework) and NICE the National Institute for Clinical Excellence set standards and put polices in place for every health care professional to follow, all patients with diabetes present with an ulcer must be referred on to a multidisciplinary team to receive the best care possible. The multidisciplinary team consists highly trained podiatrist, diabetologist, consultant, nurses, orthotists all of which specialises in complications of the foot and lower limb (NICE 2004). The dressing was removed the wound measured a reduction in depth and circumference 7mm x 6mm depth 3mm, exudate levels where low, there were no clinical signs of infection, no maceration or further callus formation, the same dressing was applied and along with padding. A further appointment was made for seven day’s time , ideally the dressing change should be five days but due to staff sickness this was not possible. At this appointment Mr Sim had seen the G.P who had referred him to a bereavement councillor.   The diabetes Centre had furthermore made a referral to the orthopaedic department who are fitting Mr Sim for orthopaedic footwear for pressure relief in accordance with NICE guidelines (2008). On conclusion the outcome for this case study was a positive one, the patient was assessed holistically to identify and factors which may hinder the healing process, this not only includes the factors directly affecting the wound but also indirectly by affecting the patients qua lity of life including dealing with bereavement, housing issues etc.   The Department of Health (DH 2008) stated â€Å"Delivering improvements for people with long term conditions is not just about treating illness, it is about delivering personalised, responsive, holistic care in the full context of how people live their lives.   Our journey to achieve this has started, our challenge is to continue to take it forward and the evidence compels us to do this†.

Introduction to the Reserve Ratio

Introduction to the Reserve Ratio The reserve ratio is the fraction of total deposits that a bank keeps on hand as reserves (i.e. cash in the vault). Technically, the reserve ratio can also take the form of a required reserve ratio, or the fraction of deposits that a bank is required to keep on hand as reserves, or an excess reserve ratio, the fraction of total deposits that a bank chooses to keep as reserves above and beyond what it is required to hold. Now that weve explored the conceptual definition, lets look at a question related to the reserve ratio. Suppose the required reserve ratio is 0.2. If an extra $20 billion in reserves is injected into the banking system through an open market purchase of bonds, by how much can demand deposits increase? Would your answer be different if the required reserve ratio was 0.1? First, well examine what the required reserve ratio is. What Is the Reserve Ratio? The reserve ratio is the percentage of depositors bank balances that the banks have on hand. So if a bank has $10 million in deposits, and $1.5 million of those are currently in the bank, then the bank has a reserve ratio of 15%. In most countries, banks are required to keep a minimum percentage of deposits on hand, known as the required reserve ratio.This required reserve ratio is put in place to ensure that banks do not run out of cash on hand to meet the demand for withdrawals. What do the banks do with the money they dont keep on hand? They loan it out to other customers! Knowing this, we can figure out what happens when the money supply increases. When the Federal Reserve buys bonds on the open market, it buys those bonds from investors, increasing the amount of cash those investors hold. They can now do one of two things with the money: Put it in the bank.Use it to make a purchase (such as a consumer good, or a financial investment like a stock or bond) Its possible they could decide to put the money under their mattress or burn it, but generally, the money will either be spent or put into the bank. If every investor who sold a bond put her money in the bank, bank balances would initially increase by $20 billion dollars. Its likely that some of them will spend the money. When they spend the money, theyre essentially transferring the money to someone else. That someone else will now either put the money in the bank or spend it. Eventually, all of that 20 billion dollars will be put into the bank. So bank balances rise by $20 billion. If the reserve ratio is 20%, then the banks are required to keep $4 billion on hand. The other $16 billion they can loan out. What happens to that $16 billion the banks make in loans? Well, it is either put back into banks, or it is spent. But as before, eventually, the money has to find its way back to a bank. So bank balances rise by an additional $16 billion. Since the reserve ratio is 20%, the bank must hold onto $3.2 billion (20% of $16 billion). That leaves $12.8 billion available to be loaned out. Note that the $12.8 billion is 80% of $16 billion, and $16 billion is 80% of $20 billion. In the first period of the cycle, the bank could loan out 80% of $20 billion, in the second period of the cycle, the bank could loan out 80% of 80% of $20 billion, and so on. Thus the amount of money the bank can loan out in some period ​n of the cycle is given by: $20 billion * (80%)n where n represents what period we are in. To think of the problem more generally, we need to define a few variables: Variables Let A be the amount of money injected into the system (in our case, $20 billion dollars)Let r be the required reserve ratio (in our case 20%).Let T be the total amount the bank loans outAs above, n will represent the period we are in. So the amount the bank can lend out in any period is given by: A*(1-r)n This implies that the total amount the bank loans out is: T A*(1-r)1 A*(1-r)2 A*(1-r)3 ... for every period to infinity. Obviously, we cannot directly calculate the amount the bank loans out each period and sum them all together, as there are an infinite number of terms. However, from mathematics we know the following relationship holds for an infinite series: x1 x2 x3 x4 ... x / (1-x) Notice that in our equation each term is multiplied by A. If we pull that out as a common factor we have: T A[(1-r)1 (1-r)2 (1-r)3 ...] Notice that the terms in the square brackets are identical to our infinite series of x terms, with (1-r) replacing x. If we replace x with (1-r), then the series equals (1-r)/(1 - (1 - r)), which simplifies to 1/r - 1. So the total amount the bank loans out is: T A*(1/r - 1) So if A 20 billion and r 20%, then the total amount the bank loans out is: T $20 billion * (1/0.2 - 1) $80 billion. Recall that all the money that is loaned out is eventually put back into the bank. If we want to know how much total deposits go up, we also need to include the original $20 billion that was deposited in the bank. So the total increase is $100 billion dollars. We can represent the total increase in deposits (D) by the formula: D A T But since T A*(1/r - 1), we have after substitution: D A A*(1/r - 1) A*(1/r). So after all this complexity, we are left with the simple formula D A*(1/r). If our required reserve ratio were instead 0.1, total deposits would go up by $200 billion (D $20b * (1/0.1). With the simple formula D A*(1/r) we can quickly and easily determine what effect an open-market sale of bonds will have on the money supply.

Political Science - Is there a 'Clash of civilization' or a 'Clash of Essay

Political Science - Is there a 'Clash of civilization' or a 'Clash of fundamentalism' in contemporary International Relations - Essay Example While each conflict may have a unique cause, and very specific and exclusive factors that lead to the build-up and escalation, thinkers and scholars have spent considerable time and efforts in exploring and establishing any common underlying factors that may be leading to the present day conflicts. A well known proposition about the causes of conflict and clash in the current international relations is that different civilizations cannot co-exists and hence conflict is inevitable. ‘The clash of civilization’ theory was proposed by Huntington, (1993) and attributes the basic cause of all international conflict to the assumption that different civilizations are unable to interact with each other in a peaceful manner as inherently their culture, religion, values and beliefs may be contradictory. This theory had postulates that clashes between civilizations would continue to rise after the end of the Cold War. An other proposition explains the conflicts as a result of fundamentalist thinking in political and international relations. The cause of conflict therefore is not the inherent nature of the different civilizations, but the adoption of a fundamentalist outlook in dealing with other countries and people. The paper will first elaborate on the meanings of the two clashes by highlighting the works of other researchers who have contributed in the development of the concepts. Secondly, a literature survey will be conducted to gather material in support or against of The Clash of Civilization Theory, as proposed by Huntington, rests on the premise that there are basically several different kinds if civilizations, namely, the Western Civilization, The Islamic Civilization, The Sinic Civilization, The African Civilization, and The Latin American Civilization. Conflicts may arise within the nation’s boundaries where there is a

I will lead them into a world where education is of the utmost importance and yet costs the parent very little to spend on. It wont be hard to do this because the child will be home schooled by their parents, using the internet as the basis of their classroom setting. Standardized testing of the child will be done by the Department of Education thus, only the testing fees shall be charged as additional government revenue. The test will be the prerequisite to moving on to the next level of education just as in a regular school. The world that I envision is one where people will not want nor lack for anything because all the taxes collected shall go towards providing with public with as much free services as possible. This will include free medical services with nominal fees charged for major operations and procedures. Mine shall be a world with a government that is down-scaled because only the most necessary government offices shall be in place. Redundancy will not exist because government agencies will know how to multitask in the service of the people. The Utopian world that I shall lead the people to will take them back to the simpler times when people grew their own food and farming was the proud way of life that people used to sustain themselves. It is a world where sharing is the key to survival , not money. Of course I shall lead them towards this type of world and lifestyle to the best of my abilities. Whether I successfully lead them or not will depend upon whether they are willing to make sacrifices in order to achieve the utopian society that I will strive to create for everyone
