Effective Presentation Delivery Essay Example for Free

Effective Presentation Delivery Essay There are various essential features of an effective presentation. Such presentations are memorable as well as consistent. The introduction to an effective presentation usually carries an attentive-getting device, e. g. an interesting short story; a thesis statement; a statement of significance that allows the presenter to easily connect with the audience; a statement of credibility, establishing the presenter as a credible source for the message about to be delivered; and an organizational preview statement, which introduces the organization of the presentation to the audience (â€Å"Presentation,† 2007). Although first impressions are quite important, it is equally significant to maintain consistency for a presentation to be effective – that is, to deliver the message that it ought to (Chatterjee, 2005). If a presentation employs visuals to effectively deliver the message that is planned for the audience, these visuals should appear consistent as well as coherent. The layout of the presentation, and the fonts, for example, should not appear out of place. In addition, the presentation should look as though it is continuous. Given that the presenter must keep the attention of the audience, interruptions in the flow of the message must be avoided (â€Å"Presentation,† 2007). The presenter must remain enthusiastic about his or her message throughout its delivery (Chatterjee). However, the ending of a presentation is equally essential to focus on. An effective presentation normally ends with a brief summary of the main ideas; reinforces the objectives of the effort; and employs an attention-getting device so as to be memorable. If the presenter holds a question and answer session before ending the presentation, a summary statement after the session is important. Moreover, effective presenters are known to frame the questions and answers around the purposes of their presentations. Such presenters also prepare for the questions beforehand (â€Å"Presentation†). Understanding the audience as best as possible, effective presenters convince the audience to ultimately respond to the information presented.

Motivations Of Greed In Civil War Politics Essay

Motivations Of Greed In Civil War Politics Essay Civil war is a form of conflict and security threats which causes poverty and impedes growth and development, Civil war is the most common form of massive violence and is highly destructive to society, life and the economy. James D. Fearon (2006) explained civil war to be a violent conflict between organized groups within a country that are fighting over control of the government, one sides separatist goals, or some divisive government policy, it is an intrastate war fought as a result of a rising insurgence against the government. Most writers believe that not all conflicts are civil war, for a conflict to be recorded as a civil war, 1000 people must have been killed with at least 100 from each side. Every society is characterized by certain degree of conflict over economic services, political and civil rights, access to social services and employment opportunity. These conflicts are triggered by discrimination against specific group, region, religion, social class, ethnicity or a c ombination of any of these factors (Murshed and Addison). Civil wars are characterized by wide spread losses of lives more of which are civilian women and children, cases of rape and lawless society as the state power falls, powers are only with those holding weapons during war. Civil war has a huge economic impact on a nations economy as most of the resources are directed to destruction, skills are lost and the damage on the infrastructure cripples economic development and activity. For instance the loss of electricity supplies during war hinders production activities and transportation, the uncertainty that war brings, discourages investment, studies have shown that countries grow at approximately 2.2 percent slower during war than during peace. (Heo, 2007, p.11) The impact of civil war is largely influenced by the nature of the countrys economy. Countries with strategic resources such as diamonds and oil would have a higher impact on global economy compared to countries with limited resources i.e. the conflict in Iraq reduced oil production and caused the international price of oil to increase. Civil war is much more common than international war; most conflicts have occurred within the confines of a sovereign state and put two or more groups against the government or against one another, (Heo, 2007 p.12 and Collier and Sambanis, 2005). Civil war has been a major conflict since World War II, especially after decolonization of the British empires in certain region i.e. Africa. Since 1990s, there have been a large body of research on the causes of civil wars, the most popular understanding of the causes of civil war and results analyzed by economist are termed Greed and Grievance. In this paper we are going to look at some civil war since post -world war II, causes of civil war and the greed and grievance cause of civil wars. Some Civil Wars since Post- World War II Civil wars have been a major conflict since World War II. A total of 225 armed conflicts from 1946 to 2001 were recorded of which 163 were conflict that occurred between the government of a state and internal opposition groups without the intervention from other states. According to Heo (2007), full scale civil war started in Costa Rica in March 1948, when President Teodoro Picado Michalski prolonged the transfer of power after he lost the presidential election; there was a war with an estimated death of 1,000. 1956 to 1959 Cuban communist revolution and civil war took place, 5,000 lives were lost during the war. The fighting in Lebanon between several religious and political factions took place in 1958 and ended in 1959 with 1,300 deaths. After independence in 1960, tensions between the Turkish minority and the Greek majority increased in Cyprus, inter communal conflict and civil war took place from 1963 to1967, an approximate of 1,000 people died, (Heo, 2007, P.2-3). Nigeria also experienced civil war in the late 1967, an intrastate conflict between the self-proclaimed republic of Biafra and the Nigerian military government (Uppsala). Another war returned to Lebanon in 1975 to 1976 between the Christians and the Muslims, an approximate of 60,000 people died, the war continued in Lebanon at irregular intervals with many serious violent outbreak until 1992. Uganda experienced civil war from 1981-1994, as the revolt against the government established after the overthrow of Major General Idi Amin grew, it was the precursor for the war in Uganda, the war caused more than 500,000 lives. The insurgence against the Papua New Guinea government which started in Bougainville island in1988 took many lives, this crisis originated as a result of the growing concerns over the operation of the Panguna gold mine and copper. War continued in Cambodia when the extreme communist group was overthrown in 1979 by Vietnam, the nature of the war changed when the Vietname se withdrew in1989, (Heo, 2007, 3-4). Civil war continued throughout the world at different time in different region, but is said to be more common in some regions particularly the developing Asia (east and south Asia and Oceania), they have had a very high incidence of war from 1950 -2001. Latin America also witnessed a severe conflict in the 1980s and former Soviet Union in the 1990s. In the 1970s and 1980s, there was more bloodshed in sub-Saharan Africa and the Middle East. But by the end of the 1990s, more people were being killed in sub-Saharan Africas war than in the other parts of the world put together, (Croker et al, 2007). Source: Uppsala conflict data programme 18/02/2010 Causes of Civil War Data has shown that conflicts are more common in low income Africa; Collier (2007) developed the notion of the conflict trap to understand why conflicts are highly centered in low income Africa. This traps which are: natural resource trap, the trap of being landlocked with bad neighbors, the conflict trap and the trap of bad governance in a small country, shows how different economic, social and political factors make a country vulnerable to civil wars. Global data analyzed by Paul Collier and Anke Hoeffler covering forty years to understand why some country at most times have overcome civil war, and why others could not, they used statistical approach to see what factor in a society can trigger civil war; this includes social factors (like inequality, ethnic and religious composition of the society), politics (the level of democratic political rights), history (like decolonization time) and economic factors (Collier 2004). The most dominant of all are economic factors, according to Collier (2004), there are three factors that could trigger civil war; a countrys rate of growth, the level of income and structure. If a country is poor and is dependent upon natural resource exports, the country is likely to experience a civil. Africa is one region with such economic characteristics and explains the reason for the high rate of civil war in Africa. Africa also has a large ethnic difference as most of the wars are fought amongst ethnic group e.g. the hutu and the Tutsi war in Rwanda. These conflicts can be traced to the power structure created by the colonial rulers as they grouped long-feuding tribes under the same national identity. The power passed on from the colonial masters made one group to rule over the other group which later turned to severe inter-tribal rivalry and has now turned into conflict. As tribalism grew, the fight for central power and control of natural resources increased, this was the c ase of democratic republic of Congo, Angola, Liberia and Sierra Leone as their greed grew for the control of natural resources (Rupesinghe and Anderlini, 1998) The greed cause of civil wars The greed causes of civil war are common amongst countries with lootable natural resource and are dependent on these resources. Collier (2004), explained that these natural resources yield what is termed rents- meaning making more profits that are higher than the normal level needed. The selfish desire to control these natural resources creates a politics of corruption and a politics of violence as these natural resources can also be used to finance opportunistic rebellions. According to Collier (2004), there are six ways by which natural resource rents can increase the risk of violence, four of which involves political economy and the other two are straight economy. The political economy involves the struggle to control the revenues from the natural resources, these rent-seeking shifts public funds from its original purpose of achieving all the necessities for the supply of public goods, providing low or no social and economic infrastructure that the society needs. The society loses twice as other resources are used frivolously in the struggle for resource rents and the provision for public goods drops. Nigeria provides a good example of this kind of politics for oil rents. Natural resources can also cause civil war by detaching the government. This is because governments that are rich in natural resources do not need other tax revenue from their electorates, unlike in some societies where electors pay high taxes and they question the government on how the tax money is used. (No taxation without representation). But this is indeed not the same with countries rich in natural resources; the government is able to disregard the interest of the population (No representation without taxation). Some society believes that the resource rents does not belong to the common people, hence the detachment. Mobutu of Zaire is a striking example of this detachment. Natural resources also leads to secessionist political movements as the inhabitants of that area might feel that their resources are being embezzled by corrupt and alien elite. Most African secessionist war has often been associated with natural resources; Kanga, Biafra and Cabinda are examples of such wars. The last political route by which natural resources can advocate civil war is that it provides funds used to finance rebel groups. Leaders can purchase arms and also pay recruits from the revenue gotten from these resources. Rebel groups have access to natural resources in different ways. One is to protect the company or exporters, to have their own extractive businesses; another is the concession of natural resource rights in anticipation to finally have control over the territory. The gangs in the Niger delta region of Nigeria, the rebels of Laurent Kabila in Zaire, the RUF in Sierra Leone, and the Sasson-Nguesso in Congo Brazzaville, are examples of rebels financed from the proceeds of natural resources. The work of Fearon (2004) concludes that civil war resulting from coup or revolutions tends to be short because the technology for coup depends on the weakness of the security apparatus. Whereas civil war involving natural resources or land tends to last longer, it can also last long if rebel groups have access to contraband goods like cocaine. The grievance cause of civil war This is a popular view that rebels are motivated by genuine and intense grievance; rebels are heroes fighting for justice. Based on analysis, rebellions are seen as a form of organized violence; both parties to civil war have different explanations for their actions. The rebel organization hires a public relations firm to help push their explanation for their movement and the opposition party would also hire a public relation firm. Most explanation from rebels groups are usually what Collier (2007) called the litany of grievances against the government for its oppression, unfairness, and perhaps victimization. This victimization could be on some area of the population that the rebel organization represents. Rebel movements are driven by intense violence, by the intense conditions of the rebels or the group they represent (Cited in Crocker et al, 2007). Berdal and Malone (2000) explained that rebels litany or narratives as they may call it are based on four factors which are; first economic inequality this involves unequal distribution of income, unequal allocation and ownership of resources and assets, unequal distribution of resources and anything that has to do with increasing poverty rather than reducing it would provide a fertile ground for insurgency and readily available combatants, this case was common in central Africa (Berdal and Malone, 2000; Murshed and Addison). The second narratives of grievance is based on religious or ethnic hatred; this also depends on the ethnic and religious composition of the state (ethnic and religious diversity), civil war caused by ethnic and religious difference has always been based on power, where the other group does not want the other group to rule over them as a result of perceived discrimination in public office, this was the case of the Northern Nigeria and self proclaimed Biafra in th e late 1960s, the Tutsi superiority and the Hutus inferiority in Rwanda as they both struggled to gain a place in the emerging democratic institution of the country (Uppsala). This can also be mere religious hatred, the war in Lebanon 1975 to 1976 between the Christians and the Muslims, such religious conflicts are happening in Nigeria till now. The third narrative of grievance is based on lack of political rights; if a government of a state is perceived to be autocratic, people would want to overthrow the government and this result to war in the fight for democracy, the insurgency in Romania is often regarded as a fight for democracy. The final narrative of grievance is based on government economic incompetence; according to Berdal and Malone (2000) if a government is seen to inflict sufficient economic misery on its population, it may face an uprising. This was the case in Uganda in the early 1980s; this is usually a case of mismanagement and a fallen state, Latin America, the for mer Soviet Union has suffered economic mismanagements. Corruption in these countries has also helped fuel conflict and prolonged misery on the population. The failure of the government to provide the needs of its people and security could lead them to rely on more ethnic ties which can trigger civil war as they fight over economic resources (Berdal and Malone, 2000; Murshed and Addison pg. 5). The interaction of greed and grievance Government and rebel groups may exploit civilians in other to fight a war or may fight a war in order to exploit civilians. The misery inflicted on civilians gradually creates their own justification like in Sudan; the misery inflicted on the civilians strengthened the civilians. The idea of civil war provides a suitable disguise both for greed and grievance. Rebels are thought by some economist to be opportunist and their grievances are most times deliberately forged. Some economist use the term predators of productive economic activities they believe that rebels are not heroes fighting for a reasonable cause but lust for powers and loots. Rebels use war as a means to exploit civilians, they may hope for government to commit atrocities which give them an opportunity to fight for a true or false cause. This group including the government officials, soldiers, and traders uses conflict period as an opportunity to plunder, Democratic republic of Congo and former Yugoslavia only to name but two among many are examples of such practice. For most people, conflict time is a time for them to make more money apart from their usual salaries, during warfare; money is gotten from those whose lives are spared from being massacred. War time may also lead to inflation which is very profitable for some as there may be trade restrictions from government and only those officials who are able to infraction the law can have their businesses going but at a very high cost. On the other hand, there might be no trade restriction as the states power falls during conflict, goods like drugs which were not allowed to be traded in the state would be traded during war, Cambodia and Burma in Asia, Sudan, Angola, Sierra Leone, and Somalia in Africa, Colombia and Peru in Latin America. War may also bring about exploitation as people are threatened to work cheaply or for free, there were cases like this in Sudan and Burma (Berdal and Malone, 2000 p. 29-30). It is very obvious that not all griev ance are true, some are just an end to a means. Conclusion Greed and grievance do play a major role in contemporary civil war, but one cannot truly measure between greed and grievance. Both greed and grievance work simultaneously to trigger civil, they both interact no matter which comes first greed or grievance the other follows, this is to say that greed triggers grievance and grievance triggers greed. Civil wars motivated by greed can be followed by genuine grievance as rebels fight for justice. people who do well out of war will not be particularly concerned at restoring peace while those who do not do well or are hurt badly will have an interest in restoring peace. As individuals in pursuit of different goals and objectives, there would always be a misunderstanding and conflict in one form or the other, Institutions have emerged to resolve civil conflicts and restore peace. Greed and grievance would therefore be irrelevant as long as these institutions called the social contract exist (Murshed).In Africa, conflict has helped bring about slow growth, poverty and underdevelopment, especially countries with natural resources which according to Fearon James are the reasons for the last longing conflicts in such countries especially in Africa. Countries should work hard to have strong institutions to restore peace within their state and international level as economic development is somewhat dependent on the level of peace and tranquility within the state.

Chaotic Curiosity or Curios Chaos

Chaotic Curiosity or Curios Chaos Abhishek Tiwari The word science comes from â€Å"scientia†, Latin word for knowledge. Webster’s dictionary defines science as â€Å"the knowledge covering the general truths of the operations of general laws, especially as obtained and tested through the scientific method and concerned with the physical world†. In a layman’s interpretation science is a systematic way to obtain the knowledge about the mystifying secrets of Mother Nature by few known facts, observations, and few approximate estimations. New theories and laws in science are proposed by using two points- 1) repetition or reproducibility of the data, and 2) computational simulation. But what happens if these fundamental rules are not followed in a system? As they say, exceptions to rules form new rules, these infringing systems fall into the category of â€Å"Chaotic systems†. Chaotic systems are those in which the distant results are practically unknowable. The Theory of Chaos rules this domain of sci ence. Today chaos theory is a field of study in mathematics with several applications in the fields of biology, cosmology, economics, engineering, meteorology, and physics. It talks about deterministic dynamic systems which are not just highly but infinitely sensitive to the initial conditions. Under such circumstances even with a fraction of difference in the initial stages would yield into complete different outcomes every time the process is started hence defying the first basic rule in experimentation. Every technology is built with its own error, limitations and approximation, and therefore computer simulation of such a dynamic system to know about its fate at certain point in space-time would either require a huge amount of initially defined components or a long time calculations which would still differ with the actual outcome. In other words the deterministic nature of such dynamic systems may not help in determining their future. Meteorologist Edward Lorenz was the first pe rson to talk about chaotic systems. He summarized this theory as, â€Å"when the present determines the future, but the approximate present does not approximately determines the future†. In 1972 Edward Lorenz wrote a paper titled as â€Å"Predictability: Does the flap of a butterfly’s wings in Brazil set off a tornado in Texas?† on the theory of Chaos. Edward Lorenz accidentally came across this topic while doing his work on weather forecast. Using a simple computer of his time, he was running a weather simulation. However due to time constraints he started his work mid way and to his astonishment he got a completely diverted results from the previous output. He concluded that the difference was generated due to the rounding-off of the numbers in the input. The consensus of the difference should practically have no effect on the immediate prediction but in a long run produced a significant difference. The word chaos is generally taken as complete disarray is a misnomer for this theory. The chaotic systems are not cluttered but are disciplined to an extent. Like we know for sure that the moon would not collide with earth in few weeks but the prediction remains uncertain for a longer time period. Similarly weather forecasts are known most accurately about a week before. Therefore chaotic systems are predictable for a while but later on with time it becomes random. The effectiveness of our prediction can be determined by following factors:- The extent of randomness acceptable The accuracy in defining the present state of the system The relative time scale (called Lyapunov time). In the hunt for defining the accurate state of the system the information increases tremendously and the uncertainty in the forecast increases exponentially over the time, thereby rendering distant forecasts meaningless. The state of the system is defined by a set number of points which tends to be accurate in describing it, but each one of it having a different fate over long duration. Thus, for a reason, chaotic systems are practically not possible in Euclidian Geometry. In 1982, Benoit Mandelbrot Published â€Å"The Fractal Geometry of Nature † in which he argues that a twine ball when observed from a far distance looks like a point, from fair distance like a ball and from close like a curved strand. He argued that the appearance of an object is dependent upon the observer and they can be fractional. The book became one of the classics for the â€Å"chaologists† as some of them called themselves. A double rod pendulum is the easiest example of a chaotic system. It f ollows the general rule and also oscillates almost in the same pattern as the pendulum but with time there arises difference of fractals which causes a large deviation. The slight initial conditions causes complete different trajectory. The Theory of chaos very soon became a law governing many interdisciplinary subjects. The field of biology has great implications as the understanding of the nervous system, and the circulatory system, are proved to fit a fractal model. Biological evolution, eye tracking disorder in schizophrenics can also be explained in mathematical form using the chaos model. The natural phenomena like earthquakes, its intensities and its distribution became easier to explain with the model of fractals. More researches can be done on such knowledge to explore the darkest realms of reality. Another such phenomena which is not completely explored by the present knowledge of science due to some limits is the Theory of Black Hole. Elbert Einstein proposed the existence of such phenomena years before astronomers actually spotted one. According to Einstein one of the fate of a giant size star is that when its nuclear fuel exhausts the force of gravity starts pulling in the mass around it. The star becomes as tiny as possible and the star becomes highly dense. When the size of the star reduces the gravitational pull increases square times and when the size decreases to such an extent that to escape from the field of gravitational influence one would need to attain the speed of light; a black hole is born. The radius at such stage is called as the event horizon. The point when black hole is formed, scientist believes that at the centre the space-time phenomenon is destroyed. It is also called the ideal black body, as it reflects no light. The idea of such a massive body from which no matter can escape was put forth by John Michell in 1783. Earlier in times, such massive objects were not seen of any importance or rather a fancy sci-fi stuffs because scientists failed to understand how gravity would affect a mass-less wave such as light. All the black holes have mass, some have angular momentum and also electric charge. Black holes are classified on the basis of their masses and independent of the other two properties. They are, namely, supermassive black holes (~400A.U), intermediate mass black hole (~1000km), stellar black hole (~30km), and micro black hole (~0.1mm). The size of the black hole is determined by the radius of the event horizon. A particle can move randomly in space when it is away from the black hole. As the particle nears the black hole more paths lead it towards event horizon and less paths away from it. Once inside event horizon the particle has only one path and that is towards the centre where the mass is concentrated. It is then no longer possible for that particle to escape. Event horizon gets its name because any event occurring inside that boundary cannot reach outside observer by any means thus making one impaired to notice if such event took place. Another phenomena that takes place to an object nearing the black hole is that the time slows down. To an observer falling into the black hole the clock ticks normally but to a distant observer the time difference is significant. This phenomena is called Gravitational time dilation and was first proposed by Elbert Einstein in his theory of Relativity. Consequently experiments were carried out and it was found that atomic clocks placed at different altitudes that caused them to experience different gravitational pull differed in nanoseconds. The difference in the time between a clock on the surface of the earth and the satellite revolving around it is significantly different making it compulsion to correct the global positioni ng system’s clock after equal intervals. The Gravitational Time dilation was wonderfully showed in the 2014 Hollywood blockbuster Interstellar. With the clock slowing down from a free falling object into the black hole the light emitted or reflected by this object changes to red. This is known as the gravitational red shift or Einstein’s shift. This primarily happens because the frequency of the light wave is slowed down by the gravitational pull of the black hole changing the color to red. Red shift is denoted by dimensionless variable (z). , Where, ÃŽ »o stands for wavelength of the electromagnetic radiation recorded by the observer, ÃŽ »e stands for the wavelength of the radiation at the source of emission. Thus red shift can be defined as the fractional change in the wavelength of the emitted radiation. There is a corresponding phenomenon to red shift known as blue shift and it occurs when some object is pulled towards a stronger gravitational pull from an area of weak gravity. However the observer free falling into the black hole does not realize these changes. Basically this means that the observer does not realize when he entered the event horizon. As per one theory when the person reaches the point of singularity i.e. the centre of the black hole where the space-time graph extends to infinity, they are crushed to infinite density and its mass is added to the mass of the black hole. Just before reaching the point of singularity the object is torn apart by the tidal forces which is often called as â€Å"spaghettification†. However this can be avoided in a charged black hole or reissner-nordstrom black hole. It is hypothetically said that the black hole takes the object to another space-time by acting as a wormhole. Since no information can be transmitted out of the event ho rizon, knowing exactly of what takes place inside is impossible and hence the mystery is still unsolved The gas falling into a gravitational well will form a disc like structure due to the conservation of angular momentum. Friction caused within this formation should heat up the gases and they would start radiating x-rays. This is known to happen around neutron stars and white dwarfs. It is called accretion of mass. It is the most efficient way of producing large amounts of energy still known about 40% as compared to nuclear fusion generating 0.7% of mass as energy. It is now accepted that the centre of every galaxy contains a supermassive black hole. The evidence of this can be the motion of stars around the centre of any galaxy. Astronomers are studying a region call Sagittarius A from the year 1995. They found that there is about 4.3 million solar mass contained in a radius of less than 0.002 light years. This mass-distance ratio is 3000 times more than the mass-distance ratio of event horizon. It is therefore conclusive that the centre homes a supermassive black hole and nothing el se like a star cluster. Stephen Hawking, in 1974, proposed that the black holes might release some radiation. These radiations are hypothetical and are called Hawking radiations. It is suggested that if black holes emit radiations they may shrink. To this, Hawking suggested that the microwave radiation entering the black hole has far more energy in comparison to the energy emitted. In 1970’s he proposed that the total area of a black hole can never decrease even if two of them collide and merge. This became the second law of black hole mechanics and has striking similarity to second law of thermodynamics which states that the entropy of universe continues to increase. As per the old thinking it was considered that the black holes having absolute zero temperature had zero entropy. If this was the case then the second law of thermodynamics would be violated and the entropy of the universe would decrease. Therefore, Bekenstein along with Hawking formulated the entropy of a black hole as follows:- Where, Entropy = S; speed of light = c; Area of black hole = A ; Newton’s constant = G; Boltzmann constant = k; and reduced Plank constant = H. One striking thing to be noticed in the equation is that the entropy is related to the area of the black hole and not its volume which is rather the case in normal entropy calculation. With many such theories put forth by the great minds the human knowledge has greatly increased. Not just that the knowledge but also the interpretation of the universe around us has greatly changed. From discovering the way to measure time to discussing about its deviation with gravity and from the time when we placed earth in the centre of universe till proving the big bang theory not just the technology has evolved but also the way of living life on the planet and knowing how greatly we affect the surroundings has been brought to daily prospects. Can this evolution or the progress of human mind be infinite? Will someday religion be taken over by pure and fundamental science? Will human evolve as the creator and destroyer of the universe? What will happen then? Among these few questions are unknown and few are unknowable which will be revealed in the course of time. But one thing is assured that the curiosity in the human brain will keep driving it to discover the perplexity of the world around him. This will eventually help science to progress in every possible dimension. The counter side to the above promises is far bigger, which justifies the fact that humans have to face limitations, some created by their own laws and some by the nature. Everything that humans make has its own errors, and it is well known that nature does not work on approximations. The point where humans cannot visualize and the power to understand gives up is the region where religion rules. May be one day science will enable mankind to have super powers or may be one day humans will succumb to the super powers of the Mother Nature.

Tupac Shakur Is Still Alive Essay -- essays research papers

Tupac Shakur Is Still Alive   Ã‚  Ã‚  Ã‚  Ã‚  On September 7, 1996, Tupac Amaru Shakur was riding in the passenger side of a black BMW driven by Marion Suge Knight, president of Death Row Records. Tupac and Suge had just finished watching Mike Tyson defeat Bruce Seldon at the MGM Grand in Las Vegas, Nevada. Tupac was standing up through the sunroof while the car was stopped at a traffic light. The Cadillac containing the gunmen passed an entourage of Tupac’s allies, many of them bodyguards. Four unidentified men pulled alongside Suge’s car, fired 13 rounds, and sped away. No one gives chase and there were no witnesses on the street. How come? Why not, especially after a heavyweight fight? Tupac was shot in multiple places including his pelvis, hand, and torso. Suge was grazed in the head w/ a slug of a bullet fragment. On Friday, September 13, 1996, he was reportedly pronounced dead at 4:03 p.m. at the University Medical Center in Las Vegas. But, did he really die? There are many suspicious deta ils about his departure that contribute to this theory. It is supposed that Tupac is still alive b/c of things said before and after his death, actions done before and after his death, and other reports.   Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"I got a big money scheme, and you ain’t even wit’ it,† 2Pac states in the song â€Å"I Ain’t Mad At Cha.† 2Pac certainly earned a lot of money by faking his death. His LP All Eyez On Me (1996), rap’s first 2 disc album, shot back up to the Billboard top 10 in the weeks following his death. His latest CD, The Don Killuminati: The Seven-Day Theory, recorded under the alias Makaveli, debuted on the Billboard charts as the number one album in the nation. By selling 664,000 copies, it surpassed the â€Å"gold† plateau in one week and is now a multi-platinum hit. Sales of his other CD’s also increased dramatically, w/ his third solo album, Me Against the World (1995), actually climbing back onto the Billboard charts.   Ã‚  Ã‚  Ã‚  Ã‚  Las Vegas is a payoff city, meaning all sorts of folks have been known to be on the take, like lawyers, doctors, press, etc. When Tupac was in the Las Vegas hospital and one of his lungs was removed, the doctors were tight-lipped about his condition. One nurse made the public statement that Tupac would live and that she was positive of it. The fact that a trained medical professional state... ...ere canceled in Los Angeles and Atlanta, both of which were open to the public.   Ã‚  Ã‚  Ã‚  Ã‚  One counterargument that may mislead people into thinking that Tupac is still alive is the fact that an autopsy picture and report were released. Have you ever been standing in a grocery line and happen to see The National Inquirer? Well, if so, then you know how pictures can be altered, right? Also, on the autopsy report, it states that he weighed 215 pounds when he only weighed 168. Not only that, but it also declares that he was 6’ 2† when he was only 5’10†.   Ã‚  Ã‚  Ã‚  Ã‚  Another counterargument that is trying to disprove his still being alive is that his mother is going around the country speaking of her son’s death. Of course she or anyone for that fact, that knows that he is still alive isn’t going to admit it. He supposedly faked his death, then why would anyone blow his cover by admitting that he is still around?   Ã‚  Ã‚  Ã‚  Ã‚  Once one summarizes all the evidence, the things said before and after his death, actions before and after his death, among other reports, it becomes obvious that Tupac Amaru Shakur is not dead.

It supposedly motivates athletes and helps them stay alert and focused while also boosting physical endurance by twenty to fifty percent. This stimulant is found naturally in sixty-three plants and is consumed by eighty percent of Americans. This white, bitter, crystalline substance is known as caffeine, and is commonly consumed in efforts to enhance athletic ability (http://gopher1.bu.edu/COHIS/substance/caffeine/about.htm). Caffeine is a very popular stimulant among athletes because most believe that it provides energy, increases alertness, and quickens reaction time. When in beverage form, caffeine reaches all body tissues within five minutes of ingestion. However, peak blood levels are reached in thirty minutes. Therefore, many cyclists consume a cup of coffee half an hour before short races begin. Others drink a bottle of coke diluted with water during the last half of longer races (http://www.roble.net/marquis/caffeine). The use of caffeine is controversial in the sports world, because it is a stimulant. In fact, the UCI forbids drinking caffeine in large quantities prior to competitions. But, why is there such a desire amongst athletes to consume this drug? Are its results really that effective? To answer these questions one must investigate how caffeine works. How does it affect the body? The exact process by which it affects the body is unknown. It is suspected that caffeine affects the nervous system by altering the perception of effort and exciting the neurons responsible for contracting muscles. It may also be accountable for causing more fat and less... ...1.

Creatine and Androstenedione: Myth vs. Reality :: Steroids

Creatine and Androstenedione: Myth vs. Reality What if there was a drug you could take that guaranteed increased energy and strength? Not only that, but it came in an easy-to-swallow capsule, it could safely and naturally increase your level of testosterone, (the most potent of muscle building hormones), and it would be perfectly legal to buy and relatively inexpensive. The sellers of creatine and androstenedione (pronounced androe-steen-die-own) make these sorts of claims although there are no long-term studies of the effectiveness or safety of these drugs. Nevertheless, retailers can’t keep them on the shelves. Their popularity has been aided by high profile athletes. Both drugs are chemicals naturally produced in the body and found in minute amounts in food, mostly red meat. But that is where the similarities end. Creatine For many years, the world’s foremost studies of creatine and its effect on athletic performance were carried out in secrecy by communist Eastern-bloc countries. But after the fall of Communism, the training and experimental drugs used on Soviet and East German Olympic athletes was revealed. Aside from exposing the truth about illegal anabolic steroid use, there was the discovery of a "vitamin" called creatine, which was quickly introduced to the U.S. and marketed as an ergogenic, or energy-enhancing supplement. Creatine was not a vitamin, however, but a synthesized blend of certain amino acids, which are the building blocks of proteins. The benefit creatine provides is increased energy for quick, anaerobic bursts of activity, such as are required in weightlifting. Athletes taking creatine can do more repetitions and sets of exercises than they could without it. Essentially, it speeds up the process of adding strength and size to the muscles by intensifying the workout. It has been compared to the way a marathon runner might saturate his muscles with carbohydrates before a race to provide endurance except that creatine strictly helps in anaerobic activities like muscle contractions. Creatine is made in small amounts by the body, and aids a substance called adenosine triphosphate (ATP), which controls all types of muscle contractions, from bench pressing 400 pounds to blinking an eye. To contract a muscle, the ATP molecule releases one of the three phosphate groups. Creatine comes into play by attaching to the free-floating phosphate and reforming into ATP. Thus, energy is provided until the creatine in the muscle is depleted. Thus, the effect of a creatine supplement is to provide the muscles with more creatine than the body can produce on its own and thus increase energy.
