Energy Generation and conservation in Fuel Cell Essay

Energy Generation and conservation in Fuel Cell - Essay Example The fuel cell energy can be tapped in several ways before. First, they can be produced from biomass. These include the agricultural waste products, wood pulps from the paper manufacturing company and other crop wastes. These products are inserted into an enclosed fume chamber where biological and chemical reactions take place. They are broken down by some microbes, and hydrogen gas is produced. Since hydrogen gas is 14 times lighter than air, it escapes at the top of the fume chamber where it is trapped and stored for use. This trapped gas is more efficient and safe for use since it does not contain a lot of other gases. During the production of hydrogen gas in a fuel cell system, the natural gas is entered into the plant and delivered to the fuel processing subsystem. At this stage, some gases like the sulfur are removed. In addition, a preheating of the mixture (fuel) is done to reach the operating temperature of the cell. The gas is the delivered to the fuel cell where it undergoes the process of electrochemical oxidation to produce electricity or heat. The cell is much efficient with its efficiency ranging from 36 to 60 percent depending on the type of fuel cell in use. In a case where conventional heat equipment is used, a higher efficiency of about 85% can be achieved. Furthermore, people can make their own Proton Exchange Membrane Fuel Cells so that they produce their own energy or electricity (Ralph 102). This process can be achieved through a series of steps.

How Will Bitcoin and Linden Dollars Affect the Economy Essay Example for Free

How Will Bitcoin and Linden Dollars Affect the Economy Essay The common issues with ‘Bitcoin’ and ‘Linden Dollars’ are that there have been suspicions these virtual currency schemes are operating as Ponzi schemes, there is a high level of anonymity with regards to these virtual currency schemes and that there is only one regulator who oversees the system. The issue of Ponzi schemes are justified for virtual currency schemes such as ‘Bitcoin’ and ‘Linden Dollars’ but for different reasons. For ‘Bitcoin’ it greatly resembles a Ponzi scheme where people can convert real currency into Bitcoins but when they want to convert Bitcoins to currency they would need to find another person who wants to buy their Bitcoins. For ‘Linden Dollars’, Second Life Banks started offering very high interest rates on deposits which led to many users in Second Life converting real currency into Linden Dollars to receive these returns. The high level of anonymity is also another issue that virtual currency schemes face as there are many risks that users of these schemes may encounter. Due to real economic transactions in Second Life, there are many people and business that have created accounts on Second Life to obtain real profits. Creating accounts on Second Life require little information and from the creation of accounts, players in the game do not know who they are actually performing transactions with as they are performing transactions behind computer screens and would not be able to judge the credibility of the other player. Due to having only one regulator who oversees the system, these virtual currency systems are decentralised and display information irregularity in the system. For ‘Bitcoin’, due to the complexity of the system not all users completely understand how it works which leads to risks some users take without realising the consequences of those risks. Creation of Monetary Value The creation of monetary values using virtual currency such as ‘Bitcoin’ and ‘Linden Dollars’ can lead to risks and implication for users of virtual currency. The creation of these two different currencies will affect their economy in different ways due to the reason for the creation of monetary value and the amount of monetary value being created. For Bitcoins, the supply of Bitcoins is not dependant on any monetary policy but instead is based on users performing a specific activity. This scheme by Bitcoin was designed so that the money supply would develop at a specific pace and in order to receive more Bitcoins, harder algorithms would need solved. Monetary Policy Implications There are many monetary policy implications from the use of virtual currency schemes both inside and outside of the virtual world. The most impactful implications from the use of these virtual currency schemes would be outside of the virtual world if these currency schemes became widely accepted throughout the world. Monetary policy implications that may arise outside the virtual world would be the way that the Central Bank would introduce policies for price stability, financial stability and payment system stability. Virtual currency schemes could have a massive impact on price stability if they substantially modify the quantity of money, impact on the velocity of money and if there is an interaction between the virtual currencies and the real economy. These factors will create different implications for current monetary policies such as exchange rates and interest rates. If the supply of money in the real world were to decrease due to virtual currency being accepted as legal tender, it will result in a change in the exchange rate between real currency and virtual currency. Virtual currency schemes could also impact on the financial stability if there is a strong connection between the real economy, high volumes of virtual currency traded and if virtual currency is widely accepted. This will impact the financial stability if the virtual currency is unstable due to lack of maturity, confidence, low volumes traded, speculation and cyberattacks. Virtual currency schemes could impact on the payment system stability as they are not regulated or overseen by a public authority figure. This will expose users to credit, liquidity, operational and legal risks due to the currency being virtual currency which has the possibility of defaulting. Payments using real currency do not face the same situation as Central Bank money is used and the Central Bank has no default risk.

Does substance abuse cause mental disorders?

Does substance abuse cause mental disorders? Dual diagnosis between drug abuse and mental illness is very common. The two problems affect and interact with each other. The number of people diagnosed with a mental illness and substance went from 210,000 to 800,000 between the years of 1998-2003. (Druss MD, Bornemann, Fry-Johnson MD, McCombs PhD, Politzer, Rust MD, 2006) Substance abuse is the most common and clinically important dual disorder among adults with severe mental illness. Studies show that fifty percent of people with mental illness also have a substance abuse problem. (Saisan, Smith, Segal, 2010) And more than half the persons with a substance abuse diagnosis also have a diagnosable mental illness. (Saisan, Smith, Segal, 2010) Clinicians believe that mental illness and substance abuse are biologically and physiologically based. Although substance abuse and mental health disorders like depression and anxiety are closely linked, one does not directly cause the other. (Saisan, Smith, Segal, 2010) Both conditions can mirror each. PROBLEM STATEMENT: More and more people are suffering from a combination of substance abuse and mental health problems. Alcohol and/or drugs are often used to relieve the symptoms of a mental illness, side effects from their medications or just to cure symptoms they are having at the time. Alcohol and drug abuse can increase original risk for mental disorders and can make symptoms of a mental health problem worse. Substance abuse and mental illness commonly co-occur due to genetic factors, environmental factors, a brain disorder and/or a development disorders. Co-occurring disorders, two disorders or illnesses occur simultaneously in the same person, they are called dual diagnosis or co morbidity. (Topics in Brief, 2007) Treatment for this dual diagnosis has not been well designed. Clients have to go a treatment facility for mental health treatment and a different facility for substance abuse treatment. This kind of treat is not successful because this leaves the client trying to cope/manger a disorder on their own. It is almost impossible for them to manger the other disorder because if they could quit on their own they would not need treatment. It can be hard to diagnose a person with a dual diagnosis of mental illness and substance abuse. One of the things that makes diagnose hard is denial by the patient. Substance abuse and mental disorders commonly co-occur because of overlapping genetic vulnerabilities, overlapping environmental triggers like stress, involvement of similar brain regions, and drug abuse and mental illness are developmental disorders. (Topics in Brief, 2007) Having a dual diagnosis put a person at greater risk for relapse. Violence and suicide attempts are also more prevalent among the dually diagnosed population.http://www.onlinerecoverysupport.com/wp-content/uploads/borderline.jpg BACKGROUND: The problem of dual diagnosis became clinically clear in the early 1980s. (Drake R. P., 2001) Substance abuse and mental illness hinders your ability to function, handle life and have a healthy social life. Mental illnesses are mental conditions that disrupt a persons thinking, feeling, mood, ability to relate to others and daily functioning. The World Health Organization has reported that four of the 10 leading causes of disability in the US are mental disorders. (National Alliance on Mental Illness, 2010) Some of the major and the most common mental illness that occur with substance abuse are manic depression, schizophrenia, bipolar disorder, attention deficit hyperactivity disorder, obsessive compulsive disorder, panic disorder, post traumatic stress disorder, generalize anxiety disorder and antisocial personality disorder. It is reported that about 57.7 million Americans experience a mental health disorder in a given year. (National Alliance on Mental Illness, 2010) Substance abuse, also known as drug abuse, refers to a maladaptive pattern of use of a substance that is not need to sustain life or to make it better. One in four US deaths can be attributed to alcohol, tobacco, or illicit drug use. (Innovatory Combating Substance Abuse, 2010) The commonly abused drugs by people with a mental illness are alcohol, cocaine and/or marijuana. Substance abuse complicates some aspect of care for a person with a mental disorder. It provides challenges for the counselor to engage the individual in treatment.http://t0.gstatic.com/images?q=tbn:HOCEVK5RjjC51M:http://i206.photobucket.com/albums/bb156/elgangster214/marijuana-2.jpg About 50% of individuals with severe mental disorders are affected by substance abuse. (Saisan, Smith, Segal, 2010) Thirty-seven percent of alcohol abusers and 53% of drug abusers also have at least on serious mental illness. (Saisan, Smith, Segal, 2010) See the chart below. The risk of developing a drug abuse problem while having a disorder goes as high as 15.5% for antisocial personality disorder and as low as 02.1% for phobias. The mental health problems that most commonly co-occur with substance abuse are depression, anxiety disorders, and bipolar disorder. (Saisan, Smith, Segal, 2010) When a person has a dual diagnosis of substance abuse and mental illness the clinician has to determine what are the symptoms/signs of the substance abuse and what are the symptoms/signs are from the mental illness. Disorders with Increased Risk of Drug Abuse Disorder Risk Antisocial personality disorder 15.5% Manic episode 14.5% Schizophrenia 10.1% Panic disorder 04. 3% Major depressive episode 04.1% Obsessive-compulsive disorder 03.4% Phobias 02.1% Source: National Institute of Mental Health. (Drug Abuse and Mental Illness Fast Facts, 2006) At least 60% of people fighting substance abuse or mental illness are fighting both at the same time. (Bouchex, 2007) Patients with mood, anxiety or drug disorders are about twice as likely to be diagnosed with the other as well. Figure 1 (Topics in Brief, 2007) The prevalence of these dual diagnoses does not mean that one condition caused the other, even if one appeared first. The high rates show the need for better treatment and treatment centers able to deal with both at the same time. http://www.nida.nih.gov/tib/images/tib_large_images/comorbid02.jpg WORKING DIAGNOSIS: Substance abuse can cause mental disorders due to the fact that, drug abuse can cause a mental illness, mental illness can lead to drug abuse, drug abuse and mental disorders are both caused by other common risk factors all three can contribute to the establishment of specific dual diagnosis of mental disorders and addiction. (Topics in Brief, 2007) FRAMEWORK/METHOD OF ANALYSIS: I began my search using Google and searched using the terms Substance abuse and Mental Illness. This resulted in nine articles that were relevant to my topic all of which I used as references. I then went to the Pub Med Central database and searched using the term substance abuse and mental illness and found many articles. I used four of those articles as references. The other references were found on website such as National Institute on Drug Abuse and the National Drug Intelligence Center. ADDITIONAL INFORMATION (LITERATURE REVIEW): This review looks at progress made in understanding the relation between drug abuse and mental illness. Volkow found that the relationship between substance abuse and mental illness is likely to reflect common contributing factors and brain substrates. (Volkow, 2001) One of the main factors substance abuse and mental illness have in common is stress. A question that still remains is the role that drug abuse has on causing psychosis in individuals with no previous psychiatric histories. Stimulant drugs induce psychosis because they increase extracellular dopamine concentration in the brain. However it does not explain why psychosis can continue after the stimulant drug is no longer present in the brain.brain image Regier, et al, broke his study down into specific mental disorders. This review found that of people with schizophrenia forty-seven percent has some form of substance abuse problem. People diagnosed with schizophrenia have a 4 times as likely then people who do not have schizophrenia to have a substance abuse problem. (Regier, et al., 1990) The odds for people diagnosed with anxiety disorders to have a substance abuse proplem were more than fourteen percent. It is believe that substance abuse may trigger mental illness in vulnerable individuals. Evidence show a complex explanation in which well-known risk factors- such as poor cognitive function, anxiety, deficient interpersonal skills, social isolation, poverty, and lack of structured activities combined to render people with mental illnesses particularly vulnerable to alcohol and drug abuse. (Drake, 2009) People that already have a mental disorder probably appear to be extremely sensitive to the effects of alcohol and other drugs, due to having a form of brain disorder. Drake, et al, explains the term dual diagnosis as misleading because people with a dual diagnosis are diverse and tend to have multiple illnesses rather than just two illnesses. Drake discusses how researchers have established some identical finding. First, co-occurrence is common. Second, dual diagnosis is associated with a variety of negative outcomes, including higher rates of relapse, hospitalization, violence, incarceration, homeless and serious infections such as HIV and hepatitis. (Drake R. P., 2001) Third, the mental health and substance abuse treatment system delivers fragmented and ineffective care. RESTATEMENT OF WORKING DIAGNOSIS (Hypothesis): There is evidence that substance abuse can lead to a mental disorder but also a mental disorder can also lead to a substance abuse, it is not known which comes first. Like the saying which comes first the chicken or the egg. It is said that having one of the diagnosis makes you vulnerable to the other. http://t0.gstatic.com/images?q=tbn:2wcgJmOO5cR8aM:http://deepwarriors.com/wp-content/uploads/2010/07/chicken-egg.jpg MANAGERIAL/POLICY RECOMMENDATIONS: Why people who are having a mental disorder are so prone to drug abuse raises a lot of questions due to the limited research done on the topic. The research so far is inconsistent and has failed to address a number of issues. There is a need for more research as well as more treatment center that are equipped to deal with dual diagnosis. The patient has two brain diseases that influence one another, and which both need treatment, at the same time. This is when dual diagnosis treatment is need. It is an approach used by clinicians to treat individuals affected by two co-occurring or coexisting conditions simultaneously. Dual diagnosis affects a person physically, mentally, spiritually, emotionally and socially. There is a need for an all-inclusive approach that identifies both disorders, evaluates both disorders, and at the same time treats both disorders. Many treatment centers now only treat one or the other. Substance abuse treatment are not recommended or designed to handle a ment al illness and vice versa. Awareness about the problem needs to be made public, so that people know the signs to look for and how to approach the person about their disorder correctly. Patients also need to be aware of the help that is available to them and support groups like Dual recovery Anonymous. There also needs to be better training for the counselors and physicians so that they will be able to better and accurately diagnosis patients. For recovery to be successful you must treats a clients addiction and mental health problem. http://www.bghealth.org/images/support%20group%20gif.gif Was Che Guevara a Successful Revolutionary? Was Che Guevara a Successful Revolutionary? The principal subject of historical debate surrounding Che Guevara is whether or not he succeeded as a revolutionary. The debate can become quite implausible as some regard him as a folk hero of mythical proportions. There is a sense of irony in that Guevara has become worldwide fascination as a commercial product, although Guevaras motive for the revolutionary uprising was to conquer capitalism. This thesis will argue the ways in which Guevaras legacy has been received and interpreted (listed below), as well as identifying the origins of his profound popularity. Description of Preliminary Research and Research Intentions: Main areas or issues you plan to discuss in your essay The overall focus is the interpretation of Che Guevara and his legacy over time. With this, the main topics of the debate are: The life of Che Guevara was one of controversy and thereby one must place emphasis into questioning the significance he holds in the pantheon of international revolutionary heroes and ideals. Herewith, the historian must evaluate Guevaras success from a political/empiricist perspective. The complete commitment to the revolutionary struggle to create a new man and a just/social order that continues to inspire those who struggle against social injustice. With this, one must investigate how these ideals impact on the post-Guevara population of modern-day society. To do this the historian must evaluate Guevaras success from a social perspective. Guevara has become a popular symbol while his image is too often dissociated from the legend that built it. With this, one must evaluate how and why his image has become a dominant face of contemporary popular culture. In relation to this debate, Guevara has ironically become an important image for money-wielding capitalists. Therefore, the historian must evaluate Guevaras success from a determinist/economic perspective. Project Synopsis The thesis explores specifically whether or not Che Guevara succeeded as a political revolutionary and a powerful icon in contemporary popular culture after his death. Guevaras life provides a significant historical debate as Guevara has often been criticised as a murderer, a hypocrite and a failure. His attempt to unite several Latin-American nations under a communist rule was unsuccessful, although he is often regarded as a hero to many of the inhabitants of these countries. The precise thesis question to be focused on is Evaluate the changing views on Ernesto Che Guevaras success and legacy following his death in 1967 to the present day. This question was developed as an investigation into how and why Guevara obtained an iconic status in society, and whether or not he is regarded as being a success or a failure. Originally, this question focused only on Guevaras failed attempt of uniting Latin-American nations and placed an inquiry into why Guevara became so popular. Through thorough research and academic critique, it was discovered that there were more sophisticated elements to the thesis question. The life of Che Guevara was one of controversy and thereby one must place emphasis into questioning the significance he holds in the pantheon of international revolutionary heroes and ideals. Guevara made a complete commitment to the revolutionary struggle to create a new man and a just/social order that continues to inspire those who struggle against social injustice. Herewith, one must investigate how these ideals impact on the post-Guevara population of modern-day society. Guevara has also become a popular symbol while his image is too often dissociated from the legend that built it. With this, one must evaluate how and why his image has become a dominant face of contemporary popular culture, as well as the face of marketisation. Different historians have produced varying answers to the specific question. In the thesis, the strength of these claims is explored in an attempt to resolve the issue of whether Guevara succeeded or not, but the sources themselves their motivation, influences and perspective are also explored to ensure that the different historical perspectives are not simply described, but evaluated. This focus question is resultantly a mix of history and historiography. Project Essay Ernesto Che Guevara remains a potent iconic presence in society, with his life the subject of new biographies, his visage on T-shirts, and his highly-regarded influence in the political spectrum. The Argentinean-born guerilla leader who helped Fidel Castro seize power in Cuba in 1959 remains one of the few unsullied heroes available to the political left. His thoughts (as evidenced in his book, Guerilla Warfare) on revolutionary strategy, bureaucracy, education, economics, the role of the party, internationalism, attitude to work and democratic centralism have been regarded as the force behind the Latin-American Revolutions. Guevara had an indomitable belief in the worth of education and was self-taught in economics and Marxism. Marxs concept that it is not enough to interpret the world, it must be transformed was at the heart of Guevaras life. Guevara strongly believed that key analytical concepts must be adapted and modified by practice. Guevara felt that the struggle against capitalism and the construction of a new socialist society required a new type of human being who would be willing to make personal sacrifices for the well-being of others. Historian Richard Harris states, His life as a revolutionary was a success as evidenced by the continuing significance he holds in the pantheon of international revolutionary heroes and ideals. The example he set of complete commitment to the revolutionary struggle to create a new man, freed from his alienation, educated and ready to struggle every day for his liberty and a just social/international order continues to inspire those who struggle against social injustice and oppression and seek to create a new social order based on the ideals of socialism. In this context, Che has in death succeeded more than he ever could have imagined. Historian Siles del Valle argues rather convincingly that Guevaras views on the new man motivated him, his comrades and the young Bolivian rev olutionaries who followed in their footsteps a few years later to sacrifice their lives for a new society and a new kind of human being. Many of the adherents of this theology of the new man established close links with popular revolutionary movements throughout the region. In Bolivia, after the failure of Guerillas guerilla movement, and in other countries such as Chile, Brazil and Peru, the most progressive sectors of the church, influenced by the ideals of liberation theology, associated themselves with Marxist and neo-Marxist revolutionary movements. In Bolivia, this tendency resulted in the participation of certain younger members of the Christian Democratic Party in a revolutionary guerilla movement that attempted to establish a base of operations in 1970 around the mining town of Teoponte, north of the capital of La Paz. Although the idea of guerilla warfare was no longer accepted as a viable form of resistance to the military regime at the time, important elements within the Bolivian people began to idealize and even venerate the guerillas. Historian Siles de Valle illustrates the importance of how Guevaras death, his concept of the new man, the ideals of liberation theology, and the political movements inspired by Guevaras example have influenced Bolivian popular literature and politics right up to the present. This influence is evident in that the first indigenous president of Bolivia, Evo Morales, is said to be re-launching Guevaras project of a peasants revolution in the country. Morales stated that he admires Guevara because, he fought for equality and for justice. He did not just care for ordinary people; he made their struggle his own. The Deputy Assistant Secretary of Defense for Western Hemisphere affairs, Roger Pardo-Maurer IV, states, You have a revolution going on in Bolivia, a revolution that potentially could have consequences as far-reaching as the Cuban revolution of 1959. What is going on in Bolivia today could have repercussions in Latin America and elsewhere that you could be dealing with for the rest of your lives. Che Guevara sought to ignite a war based on igniting a peasant revolutionà ¢Ã¢â€š ¬Ã‚ ¦ This project is back. Herewith, Evo Morales could become the countrys first authentically politically leftist president. In contrast, Historian Jay Mallin provides the argument that Guevaras influence was ineffective in Bolivia. He states that, charisma is never enough when it comes to leftist movements. The fate of Che Guevara, who failed to foment a Latin American revolution and left no coherent societal model behind for his followers, should have taught us that already. Mallin also believes that Guevara had no purpose to be in Bolivia. Mallin affirms that, the peasants displayed little or no interest in aiding him [Guevara]. During the 1950s, Bolivia had undertaken agrarian reform, and most of the peasants now owned their own land. A high-ranking Bolivian official commented: What could Che offer them? Cabinet posts? Mallins comment indicates that although Guevara was attempting to eradicate the alienation of the individuals on behalf of the population, the peasant majority perceived him as worthless as they had already been benefiting from the capitalists agrarian reform schemes. Mallin considers Guevara to be a failure due to the fact that he was a leading theoretician and advocate of guerilla warfare, but he failed in an attempt to apply his own doctrines. Since Castro came to power in 1959, he and Guevara had launched or encouraged more than a dozen guerilla operations throughout Latin America. Not one of these has succeeded in overthrowing a government; several have been wiped out completely; and some still splutter along. Although much criticism of Guevara and his legacy emanates from the political center and right, there has also been criticism from other political groups such as anarchists and civil libertarians, Bolivian officials and right-wing conservatives, some of whom considered Guevara an authoritarian, anti-working-class Stalinist, whose goal was the creation of a more bureaucratic state-Stalinist regime. Mallins irrefutable argument is that Guevara was a man of considerable capabilities, but he chose to employ these talents in pursuit of violence as a means to a political end. A doctor by profession, Guevara chose not to serve humanity selflessly, but rather to serve communism selflessly. And this indeed he did, relinquishing power and position in order to begin, literally, from scratch once again, to risk his life a new time in obedience to his tortured ideas. Therefore, Guevara can be considered a failure when evaluating his legacy within a political context. Although his attempt at unifying the Latin American nations provided him with an iconic status, the contemporary effort by politicians to follow in Guevaras footsteps has been deemed unsuccessful (except for Cuba as it still survives and was a critical reason for the Bay of Pigs Invasion in 1961), especially with the Bolivian president Evo Morales, who has little hope of fulfilling the expectations of his followers. Called the most complete human being of our age by the French philosopher Jean-Paul Sartre, Guevaras supporters believe he may yet prove to be the most important thinker and activist in Latin America since Simon Bolivar. The most important factor of Guevaras legacy after his death was his status as a popular icon, symbolizing revolution and left-wing political ideals among youngsters in Western and Middle Eastern Cultures. A dramatic photograph of Guevara taken by photographer Alberto Korda soon became one of the centurys most recognizable images, and the portrait was simplified and reproduced on a vast array of merchandise, such as T-shirts, posters, coffee mugs and baseball caps. When Guevara died, millions mourned his passing. Poets and philosophers wrote impassioned eulogies to him, musicians composed tributes, and painters rendered his portrait in a myriad of heroic poses. Marxist guerillas in Asia, Africa and Latin America anxious to revolutionize their societies held his banner aloft as they went into battle. And, as the youth in the United States and Western Europe rose up against the established order over the Vietnam War, racial prejudice, and social orthodoxy, Guevaras defiant visage became the ultimate icon of their fervent protest on influencing government policies. Guevaras body might have vanished, but his spirit has lived on; Guevara was nowhere and everywhere at once. As Jorge Castaneda so aptly states in his evaluation of Guevara, Many of us today owe the few attractive and redeeming features of our daily existence to the sixties, and Che Guevara personifies the era, if not the traits, better than anyone. Latin-American Historians Castaneda, Anderson and Taibo examine the extent to which Guevara was committed to both fomenting socialist revolution on a truly international scale and personally putting into practice his thesis that it was possible for a small but committed guerrilla fighting force to ignite a full-scale popular revolution in Latin-American nations saddled by oppressive regimes and U.S. imperialism. His commitment to these beliefs was shared by most of his closest friends and comrades as well as many admirers and sympathizers around the world. Guevara exemplified the principles of individual sacrifice, honesty, dedication to cause, and personal conviction in his beliefs. In fact, the example he created by the way he lived his life and met his death has transcended time and ideology to nurture and inspire new generations of fighters and dreamers. Guevaras defiant visage, as Anderson believes, has become the ultimate icon of revolutionary spirit and commitment in the late twentieth century. Guevara was truly a man who died for his beliefs, and because of his almost mythical self-sacrifice for his revolutionary ideals he has been the single most important figure of veneration for revolutionaries and guerilla fighters around the world. Historian Castaneda links Guevaras legacy to what he sees as the legacy of the international youth revolt that took place in the 1960s: à ¢Ã¢â€š ¬Ã‚ ¦This is the lasting legacy of that decade. It is also what made Guevara the perfect fit, the supreme emblem of that cultural revolt a man whose politics were conventional but whose attitude toward power and politics attained epic and unique dimensionsà ¢Ã¢â€š ¬Ã‚ ¦ This component of Guevaras legacy can be evidenced through the increased involvement of the New Left youth revolts during the 1960s. The New Left sought to modify, rather than overthrow capitalism. It sought to make capitalism more inclusive and better share the massive wealth the United States enjoyed in the postwar period making the New Left relevant as this was a constituent of Guevaras ideologies. Castaneda supports his argument by stating that Che can be foundà ¢Ã¢â€š ¬Ã‚ ¦in the niches reserved for cultural icons, for symbols of social uprisings that filter down de ep into the soil of society, but while there is truth in this assertion it is also clear that Guevaras legacy is greater than this. Bolivian literature, as exemplified by Harris, is testimony to the influence on Bolivian society of Ches guerilla mission and death. Though he is seen by many as a hero, opponents of Guevara, including Cuban exiles, think of him as a killer and terrorist. They point to what they see as the less savoury aspects of Guevaras life, taking the viewpoint that he was enthusiastic about executing opponents of the Cuban Revolution. Some of Guevaras writing is cited as evidence of this tendency, as quoted in an article by Alvaro Vargas Llosa. In his Message to the Tricontinental, Llosa writes of hatred as an element of struggle; unbending hatred for the enemy, which pushes a human being beyond his natural limitations, making him into an effective, violent, selective, and cold-blooded killing machine. Critics in the United States assert that Che Guevara was responsible for the torture and execution of hundreds of people in Cuban prisons, and the murder of many more peasants in the regions controlled or visited by his guerilla forces. Contrary to Guevara supporters, these critics also argue that Guevara was a blundering tactician with no recorded combat victories. While supporters point to the Battle of Santa Clara as a major victory of Guevara, historian Alvaro Vargas Llosa writes, his greatest military achievement in the fight against Batista taking the city of Santa Clara after ambushing a train with heavy reinforcements is seriously disputed. Numerous testimonies indicate that the commander of the train surrendered in advance, perhaps after taking bribes. They believe that Guevara murdered individuals on dubious grounds and took their property, seized private manors for himself, and distributed property among communist bureaucrats rather than the peasants. The critics also st ate that he helped institute forced labour camps when communist volunteerism had failed. Herewith, his social legacy has proven to be notorious as early followers of Guevara have had to transcend hate in order to be attain freedom. A corresponding element of Guevaras legacy is his success and veneration within an economic context. Guevara believed that the revolutionary regime needed to promote the development among Cubas working class of a new communist consciousness based on moral rather than material incentives. He also believed strongly that the regime needed to adopt a centralised budgetary system for the equitable allocation of resources between different sectors of the economy in order to build socialism in Cubas corrupt and underdeveloped economy. He was vehemently opposed to what has today become the market strategy in the remaining few socialist countries marketisation, material incentives, and enterprise financial self-management. Anderson believes that Guevaras image is lionised by commercial profiteers around the world. Entrepreneurs have used and abused Guevaras visage in a variety of ways including ice-cream flavours, revolutionary tacos and is even the public face of Cuba in relation to tourism . Although Guevaras Marxist and economic ideologies were systematic and meticulous, he failed at managing the Cuban economy, as he oversaw the near-collapse of sugar production, the failure of industrialisation, and the introduction of rationing. In a broader sense, some critics, such as Che-Mart (author unknown), have merchandised their dislike of Guevara by marketing burlesque T-shirts at both Guevara and his supporters, casting aspersions, for example, on what they perceive as an irony. The irony can be evidenced in that Guevara was a motivated communist who lived the last years of his life as a revolutionary figure, in order to abolish American capitalism throughout Latin America, but is now one of capitalisms hottest selling images. The creator of Che-mart.com has written, Che has marketed his brand name brilliantly over the years, selling to specific niche in the market: young people who have no clue what Che has done or what he stands for. The cash continues to flow as most coll ege dorms world-wide are being adorned with his face. This comment eradicates Guevaras initial purpose and ideals of a world free of capitalism. Herewith, Guevaras legacy in an economic context is an ironic one, as what he fought against for so many years has allowed market oligopolies to take advantage and use his well-known visage to achieve what entrepreneurs love most: large profit margins from effective market capitalism. The complex facets of Che Guevaras revolutionary movement have created a mixture of interpretations through the passage of time, causing a distortion in the Guevara legend. He is singled out from other revolutionaries by many young people in the West because he rejected a comfortable bourgeois background to fight for those who were deprived of political power and economic stability. However, as evidenced in the thesis, Guevara was unsuccessful in his fight against peasant exploitation and Western capitalism. It is for this reason that Guevaras legacy is considered as rather disproportionate and can be regarded as a failure, when evaluating his political and economic success as a revolutionary. Paradoxically, Guevara can be considered a success as he has become a popular symbol while his image is too often dissociated from the philosophy that built it. It is the vulnerability of Guevaras spirit that makes him a contemporary hero although he might have failed as a revolutionary, he ha s somehow retained a powerful hold on the popular imagination, seeming to transcend time and place; his legacy continues to influence not only those who were inspired by him then but also those who are discovering him today.

Code Switching in Language Acquisition Essay -- English Language Essay

Code Switching in Language Acquisition The acquisition of English as a non-native language proves quite problematic for some individuals. Because English was developed using modifications and borrowed words from scores of fundamentally different languages, it would seem to be a language which most peoples of the world could easily acquire. There should always be something about the language and structure that reflects an individual’s native tongue – whether it be phonology, syntax, or semantics. However, the very fact that English incorporates an international lexicon with the respective varied syntactical applications makes English a fairly difficult language to acquire. Research by Cummins (1987) focuses on the length of time needed to acquire English. To achieve the Basic Interpersonal Communication Skills (BICS) level, a learner must study English from one to two years. However, to acquire the higher Cognitive Academic Language Proficiency (CALP), it takes five to seven years. In the acquisition of English, a normal linguistic behavior is the embedding of words or phrases from the native language into spoken English. This is called code switching. â€Å"Baker (1993) lists 10 purposes for code switches: (1) to emphasize a point, (2) because a word is unknown in one of the languages, (3) for ease and efficiency of expression, (4) as a repetition to clarify, (5) to express group identity and status and/or to be accepted by a group, (6) to quote someone, (7) to interject in a conversation, (8) to exclude someone, (9) to cross social or ethnic boundaries, and (10) to ease tension in a conversation† (Diaz-Rico & Weed, 2002). It is my opinion that the frequency of the use of code switching as well as the purposes for... ...er the changing form of the English language over time. As new cultures and languages converged through the millennia to develop into the English with which we are familiar today, how much impact did code switching have on the eventual integration of words from other sources? How much time and how large a population of different languages would be needed to change a lexicon? In how short a time could such a change occur? The opportunity to ponder these questions might not have occurred without the benefit of having taken this course, History of the English Language. Works Cited: Cummins, J. (1979).

Development of children Essay

The social and emotional development of a childs identity and self image starts from birth. In the first five years of a childs life , children learn how to interact with others, learn what is acceptable. Every child is unique and they all develope at their own pace. Birth to 3 years- As a baby a child will overcome lots of obsticles such as hand to hand co-ordination, learning to sit up and stand, learning to feed themselves, learning to put words together. Children learn to play alongside instead of with other children, they test behaviours as they learn what is right and wrong. They need lots of emotional support from their parents. Ages 3-6 years- At this age the children will have a short attention span, They are learning self awareness and imagination, what is socially acceptable behaviour and what is not. The child will start to develope more language and communication skills and they will be starting to assert their own identity. Age 7, They will be identifying feelings and emotions, identifying dangerous situations and who to go to for help. They will be learning to identify the difference between ‘needs’ and ‘wants’. Age 8, The child will be able to express emotions in appropriate ways i.e appreciation, anger. Calm themselves and control strong emotions. Eight year olds will be proud of the fact they are able to do many things on their own and will express a desire for privacy. At the same time they will still need guidence and support from their parents.They may compare themselves to their friends and peers. Ages 9-12 , Children should have good communication skills, i.e communication care consideration and respect. Identify personal skills, recognise the difference between positive and negative friendships and understand the importance of family. Ages 12-16- this is a time where children reach sexual maturity and form an adult identity. During adolescence , physical changes in height and weight are usually a noticable change. Mood swings are common due to the increase in hormones. Between 12 and 16, they begin to imagine the possibilities life holds and start to set personal goals. Influences which may affect development in children include- -Stress -Negative experiences -Genetic illnesses, disorders and allergies -The childs background and where they may live -The influence of adults around the child -Religious social and economic factors. How might adults within a school setting encourage pupils to recognise and express thier own emotions? What are the possible signs and possible causes of emotional distress? Within school teachers can encourage children to recognise and express their emotions through role playing, art & design, drama, music, poatry and stories. These can provide an important opportunity for developing self confidence. An example of this is circle time sessions, these provide social and emotional learning. The class of pupils sit in a circle, exchanging ideas and feelings on different topics which are important to them . As they are sat in a circle, there is no leader, they are all equal and all have the opportunity to speak. Pupils can bring their own ideas or concerns to the circle and offer encouragement to others. Most schools have a school council where pupils can take part in desicion making. Students can bring up school improvement issues or issues affecting the classroom. Possible causes of emotional distress- -Problems at school, bullying or struggling with the work -Feeling left out and lonely, or having trouble making friends -Problems at home i.e parents not getting along and arguing. Maybe the parents have split up or the child has a new family member. -Death of a pet or relative -Abuse Possible signs of emotional distress- -Refusing to go to school -Difficulty learning -illness -Sad, frequent crying -Nightmare, difficulty sleeping -Moody and temper tantrums -Anxeity and panic attacks -Unable to concentrate -Unable to eat In teenagers some other signs could include -Alcohol/drug abuse -Violence/thefts -Not looking after themselves or over-concern with thier appearence -Self harm. Task 7 , Describe your expected role in the care and support of Individual pupils. A teaching assistant would provide care & support by encouraging the child to concentrate on what has been asked of them. Some children will require more one on one attention to help them to understand. This could involve repeating and explaining instructions from the teacher in a more simple manner. Some pupils may need extra help finding thier way around the school and getting to class rooms on time. In younger children, assisting them in the bathroom, and helping them to get dressed. Helping disabled children with physical activities such as swimming or P.E. The teaching assistant may be required to support children outside of school too, such as educational visits. Good quality relationships between children and teachers are very important when providing support, whether the relationship is through a single lesson or over a number of lessons. To gain a good relationship the teaching assistant should use good communication skills, such as friendly body language, eye contact, listening and showing respect. Greet the children by name, even out of class. Show some interest in their interests. Celebrate their achievements and display their work. What possible problems may you encounter and briefly describe how you might deal with each case? Through day to day contact with pupils, staff have an important role to play in noticing indicators of possible problems, Such as peer pressure and internal group dynamics. This could result in misunderstandings, strong emotions and class disruptions.The teaching assistant should recognise uncharacteristic behaviour patterns in pupils and deal with any difficulities which could damage the relationship with the pupil. Some problems a teaching assistant may encounter could be a disruptive pupil questioning authority, unhappy with marks they have been given on there work. A student may be emotionally unstable and become aggressive towards the staff. Constant disruptions prevent other students from concentrating on their work. Teaching assistants should always act within the policies and codes of conduct so they do not put themselves into situations that could lead to misunderstanding or accusations. When responding to these situations , the teaching assistant should remind the pupils of class room rules. The pupil may want to back track on what has been said. This should be honoured but remind the pupil that these disruptions will not be tolerated. If the problem is repeated the student should be removed from the classroom and the problem discussed with a supervisor. These incidents should be recorded. What is your role in responding to accidents and aliments? The teaching assistant does not have the sole responsibility for the safety of pupils and staff but if an emergency should arise the teaching assitant will need to act fast- – The teaching assistant should report any changes to a childs well-being to the teacher immediately. – Alert the emmergency services if necessary and obtain medical equipment for the first aider. – Reassure the pupil and make them comfortable. – Comply with the schools policy about recording a childs health. -Once the situation is stable , the parents should be notified. List common childhood illnesses and briefly discribe how you would recognise the symptoms of those illnesses in the children that you support

buy custom Securing The Companys Servers essay Introduction Any serious company cannot ignore the importance of securing its Windows and Unix/Linux servers from known shortcomings/vulnerabilities. This is due to the fact that the Windows machines may end up having serious security problems. As a matter of fact, Windows has a bad security record when it comes to operating systems (Dubin, 2005, p. 123). There is need for the company to create a set of layered defenses and avoid the idea of running capricious programs. It is also better for the company to substitute programs that have a terrible security track record with more reliable programs (Dubin, 2005, p. 127). The role of the Company information security officers is to ensure that the windows and Unix/Linux servers are secured from shortcomings and vulnerabilities; otherwise the company may risk being targeted by hackers (Brown, 2011, p. 58). The dynamic internet ecosystem sees the myriad of VLAN switches, firewalls, routers, and other devices, thus making servers and devices unreachable from a simple configuration error (Brown, 2011, p. 185-9). Today, cyber criminals are more organized than before, it is therefore paramount for the company to react with focus and effective stratagem in the key areas of technology (Brown, 2011, p. 219). Information security officers are therefore properly trained and well informed of all advancements regarding technological improvements in the communication industry. For example, the security personnel are well trained to monitor occurrences of reverse social engineering, social engineering and shulder surfing and how to avoid them (Dubin, 2005, p. 128). Securing Company Network Servers As the Information Security Officer, I will give priority to the use of digital certificates in company servers security. The installation and use of digital certificates will enhance optimal management and security ofClient Access servers. This can be installed with a default self-signed digital certificate (Danseglio, 2005, p.175). The digital certificate will help the company since it authenticates the holder. This will secure the servers from unauthorized users. In order to ensure safety and security of data that is exchanged online, digital certificates must be considered. It helps in protecting company and client data from theft or tampering by hackers (Danseglio, 2005, p.175-176). To ensure secure connectivity between the management and the client the company and client servers must be secured. I will thus advocate for the installation and use of server certificates. This will limit incidences of theft and hackings from server criminals. The server certificate helps in enhancing client server authentication (Danseglio, 2005, p.123).This will provide the company with a stronger server security. It will demand that a client or any other user of the company server supply a valid trusted certificate. To further support server and information security, I will recommend and introduce the use of trust model certification. For example, the hierarchical trust model will protect the company and client information. Hackers interccept emails and confidential information through email interception if the servers are not secured. The hierarchical trust model ensures that users of the company server have valid certification for accessing the company servers (Brown, 2011, p. 185-9). This will help in enhancing server security. This high security system will enhance protection of the servers against spyware and browser hijackers. The Importance of Securing Windows and Unix/Linux Servers from Shortcomings/ Vulnerabilities Attacks on company software are now very serious crimes in the world today. It is therefore very important for the company information security officers to protect its servers by ensuring that certificate authorities are only with the authorized personnel to reduce chances of sharing adware sites and also chances of social engineering (Brown, 2011, p. 75). Furthermore, there is a possibility of the computer hackers waging cyber warfare against the company. The companys employees may also be at risk of falling prey to credit card fraud and rob it of lots of money and can only avoid this by employing the use of secure socket layer, wired equivalent privacy or transport layer security (Brown, 2011, p. 75-6). In conclusion, in pursuing the efforts to secure the company servers, it is very important for the company to develop an infrastructure security that will improve its Network Operations Center security and confidentiality. Developing a secure and efficient server room is a priority for the information and communication in the company. Buy custom Securing The Companys Servers essay
