Environment and Global Warming Essay

Global warming has been a major problem for the last one decade or so all over the world. The climate is changing and the temperatures on the earth surface are warming up as a result of increase in amount of green house gases (GHGs) such as carbon dioxide emitted into the atmosphere. Global warming is defined as an increase in the average earth’s temperatures which as result leads to a change in the overall global climate. The impacts of global warming are quite diverse and they include ecosystem instability, a rise in sea level, increase in pests and diseases, health problems, loss of environmental beauty due to extreme weather conditions such as floods, hurricanes and so fourth (Abarbanel et al. , 2002, 22-23, 57-63). Global warming has been found to be mainly caused by human activities resulting from over reliance on fossil fuels as a source of energy which increase the green house gases emissions into the atmosphere. Research has also shown another side of global warming whereby, air pollutants emitted by fossil fuels are responsible for making clouds to reflect more sun’s rays back to the space. This effect is known as global dimming and it leads to less light reaching the earth surface. This global dimming is responsible for causing droughts due to lack of rain especially in the Northern Hemisphere and it also camouflages the actual effects of global warming leading to their underestimation (Abbot et al. , 2000, 159-176). The effects of global warming on the environment are very dangerous and expensive and all the governments in the world agree that something must be done. In this respect, the united nations have come up with a framework convention on climate change which is responsible for coming up with agreements such as the Kyoto protocol among others. The Kyoto protocol is an international agreement passed by the United Nations Framework Convention on Climate (UNFCCC) back in 1994 which was aimed at addressing global warming and climate change issues all over the world. This agreement sets targets for all the industrialised nations in the world which they are expected to abide by in order to reduce the amount of green house gases emitted by those industries located in the respective nations. This protocol is considered as the greatest agreement reached by members of the United Nations which is bound to protect the environment and ensure sustainable development. How a national policy can help to address a global problem. National policies have a great role to play in tackling major national and global challenges such as climate change, globalisation, sustainable energy needs and so forth. The solutions to such problems require innovations which are able to see beyond the problem awareness and come up with solutions aimed at lessening their environmental and economic impacts on a long term basis. Such issues more often than not require the implementation of a national policy which will address the problem both nationally and internationally. A policy is meant to ensure that the problem is addressed from a central point of view and that all the concerned parties are speaking in one voice. An example of a global problem which is currently causing major concerns in the whole world is global warming. Although its effects are largely felt in the industrialised countries, the overall effects of climate change are evident in all nations because the pollutions emitted in one part of the globe quickly disperse to all other parts of the globe (Hay 2002). With growing concern on this problem of global warming and carbon pollution, a national policy for sustainable development is essential to address this problem and come up with rules and regulations aimed at controlling the emission of carbon pollutants and other green house gases into the atmosphere. To effectively address the effects of global warming and climate changes, all the world governments must come up with national environmental policies, efficient technological strategies and invent new sources of energy which are cleaner and more sustainable. Unlike common environmental policies such as the ones set by the United Nations and other world organisations, national policies created by individual countries focused towards addressing a certain global problem are bound to be more effective because such measures are bound to achieve abatements which are in line with the national interests at the lowest national costs possible. For instance, to address the issue of global warming, Australia has come up with a three-pillar national policy aimed at reducing the amount of pollutants released to the atmosphere by its industries and as a result, the government has had to make some economic reforms which are favourable to its economic stability in order to accommodate this policy (Miller & Tyler, 1987, 19-23). Australia’s national policy in addressing global warming Australia has been vulnerable to climate changes and severe repercussions of problems associated with poorly designed policies aimed at addressing this issue. An intergovernmental Panel on Climate Change (IPCC) released a report in 2007 indicating that the Australia’s average climate is expected to change by about five degrees by the year 2070 due to the high rate of emission of GHGs in the country unless the government finds a quick and lasting solution to this global threat (Steger et al. , 2004, 33-46). Such a temperature change is bound to affect the ecosystems, energy resources, population health, agriculture, tourism as well as other sectors of the nation’s economy. Some of this effects to human beings and ecosystems are already being felt due to an increase of about 0. 9 degrees in the annual average temperatures. This effects prompted the government to facilitate the Garnaut climate change review in June and ratification of the Kyoto protocol on 3rd Dec 2007 as a way of demonstrating the government’s commitment to addressing the global warming and climate change all over the world. By agreeing to the Kyoto protocol, the Australian government has expressed willingness to pay the price for carbon reduction as a way of dealing with global warming. The Garnaut review focused on examining the climate change and its effect on the nation’s economy and has come up with policies and policy frameworks aimed at improving sustainable development. The draft report produced after this review presented a detailed examination of the climate change and its implications on Australia as a single nation. Following the Garnaut draft report indicating that the impacts of global warming and climate change in Australia are expected to be greater than those experienced in the other developed countries, the government has decided to come up with a climate change policy to ensure a safer society, a more stable economy and less climate changes in the future. This policy is focused on addressing three major issues. That is; †¢ Reducing the amount of green house gases emitted by industries in the country. †¢ Adapting to those impacts of climate changes which can not be reversed or changed. †¢ Contributing to the achievement of a global solution to the problem of global warming. (Milutin, 2003, 42-56) The Australian government using this policy has introduced an emission trading scheme and a framework for carbon reduction which will help to reduce the GHGs emission by up to 60 percent by the year 2050. A reduction in the national GHGs emission will put Australia in a better position to influence the international communities in working towards a low carbon environment (Julian, 2003, 495-503). In addition, the Australian government is committed to promoting an industrial policy aimed at facilitating investment in cleaner, greener and more sustainable energy resources and increasing the economic opportunities in the country. This industry policy has helped to develop comprehensive strategies which include local content rules and purchasing policies to provide long term solutions to climate change (Derek, 2002, 115-120). According to the environmental policies set by the Australian government, the environmental standards for its industries are set very high in order to restrict them from releasing pollutants to the atmosphere (Migeotte, 2002, 519-520). The Australia’s domestic policies are bound to affect the international credibility and the ability to acquire a global solution to global warming. The long term national target which is meant to reduce the emissions by about 60 percent before the year 2050 places the total global effort and carbon pollution schemes in a better position to achieving a solution to the worldwide problem and thus, this national policy is a step in the right direction. Conclusion Global warming presents a great environmental, social and economic challenge which requires urgent attention from governments all over the globe. The Australian government has done a lot to show that it is committed to eliminating this global problem through establishment of an environmental policy and ratification of the Kyoto protocols established by the United nations framework convention on climate change. This has greatly assisted the country to reduce the amount of GHGs emission and carbon pollutants into the atmosphere leading to a cleaner environment and it has helped to address the global problem at large. This shows that the use of well implemented comprehensive national policies can help to adequately address global problems such as global warming.

Psychological trauma

Deathwatches Bataan Peninsula State University Baling Campus Sandmen D. Garcia IBIS -3 Child Psychology September 11, 2014 When the punch gets stopped The flirts thing that comes to mind when people say bullying' Is punching, pushing, slapping, tripping, any physical pain that you will cause a person. And when they say ‘bully, we tend to think of it as someone as large, strong, scary, muscular guy that trips on the weak smaller guy. But as the world shift into modern times, modern versions also arise.Verbal bullying can be Just as cruel if not worse than physical bullying. And this time the emotional phase Is at stake. Not only can this cause trauma, but It also drive you crazy and cause mental Illness. The bully will give more pain mentally than physically because they will degrade their target, making them feel less about themselves. There is also this ‘cyber bullying', where the bullying steps up on the high-tech level. The bully will take on less time on going to his victim to punch him.He just texts or calls his object or uses the internet, to spread bad words bout his target. This is the issue that arouse together with the social media networks, Its negative effects In every aspect of a person, physically, mentally, emotionally. Socially. The World Wide Web Is now techno tool for these bullies to commence their operation and harass their victims online. And it doesn't stop when the target goes offline. Of course, the bullying would cause negative social views to the victims.They would not go out and socialize through any form because of the trauma and depression of being harassed online. I never experienced bullying. When I was a kid, I was sort of the bully. I don't know how It happened but I could make the other kids obey me whenever we play that time. Add to that I was being spoiled by my grandma, whenever my grandma would always give me what I want. I also remember biting my pre-school teacher during tutorials after class because I want to go home already. My aunts and uncles would tell stories on how I was kind of ruthless that time.They said I would punish the kids if they disobey me by pulling heir hair straight to the ground, and I would smash their tiny little hands by a stick many times. They say I was never stopped because my grandma would always defend me. Okay, I really was a bully. I never said what I did was right. And the important thing is that mentality was straightened, somehow. I still was to persecute, yes, persecute, the deserving to be punished, really, but I don't perform it because, of course, it was a bad thought, also I think it was, in some way, childish to bully at my GE.Although we always see the bully as the bad guy, we could perhaps understand them. If we hate them so much, we're no different to them. So let's look deep and comprehend on why these behaviors are superior to the bullies. Maybe they had a they took bullying as a defense mechanism. Bullying never really cause anything good to people. The victims would oftentimes suffer to depression, trauma, misery, inferiority, rejection, distress, and a lot more of physical, emotional, mental, social main bullying comes with.I really am against bullying. Of course, no one would want them, or their children, or brother, or sister, or friend, or anyone close to them, to be bullied and brought down. We want to end this. We want to take a stand and protect the ones we love. We wouldn't really understand bullying and why it happens to, nowadays, a lot of people unless we open our minds. And this is one of my targets as a psychology student, to know them, understand them, and to eventually make a better change.

Animals and Myriad Ways they can Kill or Heal Us Essay - 1

Animals and Myriad Ways they can Kill or Heal Us - Essay Example Introduction A lot of animals in this world are poisonous. Often they come in direct conflict with humans and become the cause of death and partial or total paralysis. This is the reason man has hated these animals for centuries. By making these animals useful, present advancement of science and technologies has changed this preconceived notion. Some of these animals are snakes, spiders, and scorpions. This paper reviews the benefits that are derived from venoms of these animals, the process of processing venom and the diseases they cure. Venom ejected by snakes can be broadly classified into four groups. These are neurotoxins, sitotoxins, hemotoxins and miotoxins. In the majority of cases, neurotoxic venom is related to the nervous system, hemotoxins is related to blood and vascular tissues and miotoxins is a combination of both neurotoxic and hemotoxic venoms. Cobra is one of those snakes whose venom is used for therapeutic purposes. Venom ejected by cobra can be classified as a ne urotoxin, a compound that affects nervous systems of human beings. Reference to cobra venom can be traced to Chinese civilization and Vedas. During the early 1900’s cobra venom was largely used as a medicine to treat people with depression, back pain, headaches and menstrual pain (The Therapeutic Uses of Cobras’ Venom Neurotoxins, n.d.). ... The homeopathic physicians prescribe venom of Asian Cobra (Naja tripudians), but in practice, venom from all types of cobra from Middle East to Philippines is taken and processed (The Therapeutic Uses, n.d.). Medical use Since 1960, snakes venom has acquired an important place in medical treatment. The compounds present in snake venom affect muscle contraction by enhancement of the hormone Bradykinin. This hormone is responsible for dilatation the blood vessels. â€Å"The peptides present in venom transform angiotensin I into another peptide, angiotensin II, which also supports constriction†. When the Bradykinin as well as other peptides are blocked, the process of ‘blood vessel constriction’ no longer functions. Only the process of dilatation takes place. This makes snake venom an effective and alternative treatment for treating symptoms of hypertension. In spite of not being a medical drug, peptide present in snake venom contains numerous chemical features which make â€Å"it indispensible for heart attacks, neurological disorders, diseases related to blood†. Some drugs that are processed from venom of snakes are Lisinopril, Enalapril, Defibrase and Captopril. More extensive use of snake venom is utilized in treating problems related with blood cells. Snake venom has also helped in development of non- peptide compounds like Aggrastat by using ‘disintegrin’, which is a toxin present in the venoms of saw- scaled viper found in Africa. The compound functions by binding fibrinogen receptors present in blood onto platelets which is performed by disintegrin, thus performing the function of a coagulant. Some compounds in snake venom, like ‘Ancrod’ enzyme of Calloselasma rhodostoma also functions as

Mental Health psychosocial intervention assignment Essay

Mental Health psychosocial intervention assignment - Essay Example The patient stated that he also hears voices that he can control as long as he does not drink and stays on his medications. Patient had stated that he had bouts of depression and has had suicidal ideations. The patient knows that he needs to be compliant with his medications and has been known not to take his medicine. In thinking about new therapies for this patient you as the nurse, doctor or as a therapist should think to include more psychosocial interventions to make him feel comfortable, so that he will want to continue to take his medications and not want to drink that he knows causes his various problems. The caregivers should think about Social training groups, relaxation skills, and various activities that will improve coping skills. When the patient first arrives at the hospital for the coming admission you could ask him if he remembers doing any of this before to see about his level of consciousness. Working with any patients like Gary the caregivers should try to figure what Coping Mechanisms should be used and not used. You will have to identify the problem and set up a goal that will help the patient learn how to deal with his problem or problems. You know that the patient has recurring depression, is an alcoholic, and he says that he hears voices and can at time become violent due to these voices. The caregivers can think of ideas that can give the patient social support and strength so that he will not rely on the voices he hears. You can check into the resources that did not work and find out why he did not use them and then you can try to find new resources that may work. Case Study Gary a 51-year old male with previous admissions, but has decided to discharge himself from the hospital AMA (Against Medical Advice). The patient has a history of Depression due to financial stress and due to this stress he drinks alcohol so much that he suffers from alcoholism. The patient admits to have suicidal ideations and has even taken an overdose of his m edications. This is the reason that is being admitted this time. Due to this overdose due to feeling stress of his financial problems and then he drinks and aggressive issues arise and the patient gets into fights when the patient hears the ‘voices’ in his head telling him to hurt other people. The patient does admit that he can control the ‘voices’ when he is compliant with his medications, but when the patient is intoxicated his mental status decreases and could become violent. The patient does not always seek help in the community due to his past behaviors. Discussion of Psychosocial Interventions A review of psychosocial interventions begins with Erikson and for this patient, Gary, he needs to work on trust versus mistrust. The patient must want and feel trust with the caregivers while in the hospital and then he must feel comfortable in his community when he is discharged from the hospital. The patient must also work on autonomy versus shame and doubt. The patient can do this by wanting to learn about the how and why that his medications must be taken regularly and that he can learn to do this on his own and that he does not have to worry about his financial problems, because he will be given ideas that will help him in the community. The patient feels alone and this brings on depression and then the drinking and all the other problems and if the patient

The effect of religious beliefs on healthcare Research Paper

The effect of religious beliefs on healthcare - Research Paper Example This paper will, therefore, determine the various effects of religious beliefs on health care and their impact. A proper determination and discussion of the effects of religious beliefs on health care entails a proper and substantive understanding of the various aspects involved in the different religions as well as the operative mechanisms of different health care facilities. Religion, despite being an element of daily encounter, it remains majorly a personal issue (Hollins, 2009). Regardless of such an observation, it is evidently clear that a religion remains a significantly important aspect to clinicians, patients, and the entire healthcare fraternity. Indeed, religion has the ability of connecting the individual to the spiritual being, which works as an aspect of empowerment and in turn, establish an element of psychological stability (Boyle, 2008). Determining the effects of religious beliefs on health care involves four major pathways. Such include health behaviors, social support, superempirical or psi, and psychological states (Salimbene, 2005). There are different religious views on health care, depending on the beliefs of a particular religion. For instance, certain religions that illnesses are results of God’s punishments to humanity, and, therefore, the most appropriate means of avoiding any kind of illnesses, one needs to refrain from sinning, which is the greatest contributing factor to illnesses and other kinds of suffering . Based on such a perspective, there are a number of aspects influencing the positive effects of religious beliefs on health care. Such perspectives are in four major aspects, which include psychological benefits, health-promoting benefits, social benefits, and caregiving (Salimbene, 2005). Religion has a correlation with improved physical and mental health. On the psychological effects, religion

Type of Federalism Essay Example | Topics and Well Written Essays - 250 words - 1

Type of Federalism - Essay Example state progress and yield concerning the economy through an aimed profession made possible by earning a degree from an institution of learning, American tradition has kept up with the decentralized control of education as facilitated via local school districts. Among the types of federalism considered to help the government support such cause, cooperative federalism appears to exhibit supreme advantage for being a system designed to summon cooperation within various levels of the government. Unlike dual federalism in which limited authorities are involved between the state and national sovereignties and permissive federalism that depends upon the approbation of the national government in control of its federal counterpart despite the powers shared between them, cooperative relationship ensures balanced distribution of capacities. This way, state education may avail of flexible financial security with fair allocation of combined resources that can provide further assistance to other areas of scholastic necessities. Moreover, cooperative federalism by principle is capable of resolving complicated issues with decentralization of learning according to the manner by which major national priorities are addressed with collaborative functions amon g governments on a common

Corporate Social Responsibility Assignment Example | Topics and Well Written Essays - 1500 words

Corporate Social Responsibility - Assignment Example Thus, CSR is simply amalgamating environmental and social concerns into business policy and procedures. Potential benefits of CSR relative to the costs for businesses and stakeholders Apparently, CSR is an ongoing responsibility held by businesses to ethically behave and economically develop while improving the quality of life of their employees and their families, over and above, that of the local community and society at large. Scholars argue that companies must be prepared to merge both the business and society through the principle of shared value. Shared value incorporates economic value that creates value for society through addressing needs and challenges.2 For instance, the Coca-Cola Company participated in a Corporate Social responsibility by sponsoring World Cup, 2010 in South Africa. In essence, the potential benefits associated to CSR include human response, risk management, brand differentiation, operating licence, and diverting attention. In human resources aspect, CSR acts as an aid to retention and recruitment especially in relation to a competitive market. Moreover, managing of risks is crucial as one of the important corporate strategies that are achievable through building a culture of doing the right thing within a corporation. Besides, the competitive market requires companies to have a unique factor that differentiates them from other brands that are in the market, thus separating them from the competition in the minds of customers. Consequently, companies tend to take substantial voluntary steps of convincing the government about their participation in social responsibility such as health and safety and environment. Never the less, companies may involve themselves in high profile CSR programs so as to divert the minds of the customers from their perceived negative impacts. Of importance to note is that CSR has cost of aiming to satisfy the customers both in product quality and ethically sourced a process that requires additional costs. In essence, companies use extra cost in creating brand loyalty, which assist in increasing revenue that is meant to attract customers. Additionally, companies have a cost of corporate social responsibility which is the capital investment. Capital investment is taken to handle a different kind of investment that a specific company prefers to take into account and find out if the investment is worthwhile.3 The importance of CSR relative to other corporate objectives Corporate objectives are goals that are normally laid down by the board of directors putting more influence on the critical factors that are necessary for company to excel in the market. Once companies are formed, the people in charge understand that social responsibilities in respect to the society must be accomplished even though it is not in the expected set out. This is because companies have different issues that they work on. For instance, a particular company may have an excellent customer but have the worst record of employment, so as to reduce the cost of the company. One crucial responsibility that companies should pay attention to is legislation. Essentially, some areas of corporate social responsibility are covered by legislation and regulation, which should be compiled by every company according to the law. Besides, public companies are expected to give reports on their environmental impacts in their own reports that are later combined to form an annual report and accounts. Consequently, companies have various laws they must follow depending on the type of firms

Extract from The Arrogance of Power (1966) by William J. Fulbright Essay

Extract from The Arrogance of Power (1966) by William J. Fulbright - Essay Example In William J. Fulbright’s essay, the author lays his ideas in a logical way basing his arguments on both past and present events. The author also looks at the main factors behind the strength and the threat facing America by not only incorporating his opinions, but also using the facts and the personal researches. Thus, it is safe to say that Fulbright’s essay is successful as it gives several valid factors to support the author’s point of argument. First, the essay is successful because of its logical arrangement. The author looks at America in the past and America in the present. For example, in the author’s analysis of American history, he argues that America is deeply rooted in democratic institutions. Though the author is looking at the present situation of America, he looks into her history in order to justify her present situation. The historical analysis of America in comparison to other nations like Russia and Germany that rose and fell because of their desire to dominate the world makes the essay not focus on opinions, but rather documented and historical facts (Brown 252). By applying historical analysis of the world events and America, in particular, the author adds validity to his essay and his arguments appear more valid than if he had just embarked on discussing America’s failure. For this reason, it can be argued that the argument is logically valid because it gives readers a good reason to accept what the writer has put forward. Secondly, the author makes his essay successful through the tactical use of tone. The author’s tone is that of concern, and he sounds honest about the situation in America. He analyses the positive aspects of America and clearly highlights his fears for her. For example, Fulbright argues that America may be taking the steps by embarking on commitments such as peace solving irrespective of her intent. The author also highlights his concerns over America

Managing Human Resources-DB 1 - Essay Example Mott, Shorser, Sprecher, and Stephen believe that Sears has demonstrated a commitment to fostering independence for people with disabilities. "There are no restrictions. They dont hold you back; Ive had four promotions in five years. (Annenberg Foundation, 1994). 1. People who have a disability are impaired in their daily ‘major activities.’ This can represent difficulties in mobility, sight, hearing and a number of other areas. It does not include alcohol or drug impairment, however. HR can be regarded as a legal watchdog in an organization—insuring that people observe the rules and don’t cross any legal boundaries, or it can serve as a source to find, motivate and promote the best class of employees for the company. The ADA compliance story at NL&C is not one of legal problems—the employees interviewed felt that they were fairly treated. Rather, it is a question of finding a group of people who can be motivated to perform above-average work and therefore lift the results of the company. Whereas it was difficult to provide aids for the handicapped in the past, new technologies have made it possible for NL&C, along with all other companies, to bring specific technology to bear at little additional cost. Some of these improvements include: In addition, jobs are now being created or redefined in a way that makes it easier and less expensive to make accommodations for the handicapped. Telecommuting, telemarketing and telephone customer service are now much easier to implement as the tools become ubiquitous. Those employees with difficulty in movement, driving or needs to stay close to a home support system are now able to participate fully in the work environment, and even to communicate with their colleagues with their ‘virtual’ presence.

The 18th dynasty Egypt Research Paper Example | Topics and Well Written Essays - 1250 words

The 18th dynasty Egypt - Research Paper Example He established the 18th dynasty that ruled Egypt. During the rule of Ahmose the First, Egypt reached new heights of wealth and power. The regions ruled by the Pharaohs extended to new frontiers in The South, East and West. The kings of Egypt built palaces and temples, which were melting pots for Egyptian art. Territorial expansion was a response to previous threats that Egypt had experienced. Before the 18th dynast gained power, several kingdoms had invaded Egypt and weakened the region (Gardner and Fred 34). As a result, Egyptians were not able to participate in artistic works because the economy was ruined by the invasions. As a response, the Egyptian empire stretched from Syria to the regions of the Horn of Africa. This opened up new avenues for practicing art and economic activities. The economy focused on building and arts. New kingdom art differed from the art of preceding ages. The art showed a range of the Egyptian arts style. The art form of this period suffered normal surfa ce changes because of the progress of the Pharaonic art. This occurred during a homogeneous cultural period that provided a platform for an evolutional artistic development. Some of the artistic pieces of the period include the statuette of Nefert-iti and Teti-sheri. Paintings included the tomb of Amen-em-het and the palace of Amarna (Gardner et al, 42). This paper seeks to study the art of Ahmose the First who built the only loyal pyramid in Abydos. Ahmose the First was an artist who built the pyramid of Ahmose. The pyramid was not built as a tomb, but as a cenotaph for Ahmose the First (Gardner et al, 47). This pyramid was the royal pyramid that was built in Abydos. Ahmose the First used rubble and sand with limestone casing to build the pyramid. These construction materials were used to keep the pyramid in shape. The pyramid did not have any chamber for burials. Ahmose renewed royal support for the construction of artistic and monumental buildings with the re-unification of Egypt . He devoted a huge amount of his productive output towards the worship and service of the traditional Egyptian gods and reviving numerous monumental constructions and arts (Aldred 16). Though his building program did not last for more than seven year, he managed to leave a lasting arts legacy. Work from Ahmose the First reign was made of fine materials. However, artisanship during this period does not march the artisanship of the previous kingdoms. Control over the Nubian and Delta region gave access to resources that are required for artwork. Silver and Gold came from Nubia and cedar fro Byblos (Aldred 23). Though the relationship between Crete and Egypt was not certain, some of the artwork of this dynasty had designs from Crete. For instance, the Minoan designs were found in objects from the period. Most importantly, Ahmose re-commissioned the Tura Limestone quarries that provided stones for the construction of monuments. Asiatic cattle were used to haul stones from the quarry. T he pyramid of Ahmose raises a number of questions. For instance, most of the Egyptian pyramids were constructed in Cairo. However, the pyramid of Ahmose is located in Abydos, which is further south of Egypt. In my opinion, Ahmose set out to worship and appease the Egyptian traditional gods (Aldred 27). As a result, he built the pyramid to the south in order to appease the god Osiris. It is vital to note that the pyramid was not

Stress and Performance Essay Example for Free

Stress and Performance Essay So far, we have seen that stress is a negative experience. We have seen the short-term negative effects that stress hormones can have on your performance, and have seen how stress can contribute to burnout. The Positive Effects of Pressure Sometimes, however, the pressures and demands that may cause stress can be positive in their effect. One example of this is where sportsmen and women flood their bodies with fight-or-flight adrenaline to power an explosive performance. Another example is where deadlines are used to motivate people who seem bored or unmotivated. We will discuss this briefly here, but throughout the rest of this site we see stress as a problem that needs to be solved. And the Negative In most work situations jobs, our stress responses causes our performance to suffer. A calm, rational, controlled and sensitive approach is usually called for in dealing with most difficult problems at work: Our social inter-relationships are just too complex not to be damaged by an aggressive approach, while a passive and withdrawn response to stress means that we can fail to assert our rights when we should. Before we look further at how to manage stress and our performance, it is important to look at the relationship between pressure and performance in a little more detail, first by looking at the idea of the â€Å"Inverted-U†, and second by looking at Flow. This is the ideal state of concentration and focus that brings excellent performance. Pressure Performance – the Inverted U The relationship between pressure and performance is explained in one of the oldest and most important ideas in stress management, the â€Å"Inverted-U† relationship between pressure and performance (see below). The Inverted-U relationship focuses on people’s performance of a task. The left hand side of the graph is easy to explain for pragmatic reasons. When there is very little pressure on us to carry out an important task, there is little incentive for us to focus energy and attention on it. This is particularly the case when there may be other, more urgent, or more interesting, tasks competing for attention. As pressure on us increases, we enter the â€Å"area of best performance†. Here, we are able to focus on the task and perform well – there is enough pressure on us to focus our attention but not so much that it disrupts our performance. The right hand side of the graph is more complex to explain. Negative Thoughts Crowd Our Minds We are all aware that we have a limited short-term memory: If you try to memorize a long list of items, you will not be able to remember more than six or eight items unless you use formal memory techniques. Similarly, although we have huge processing power in our brains, we cannot be conscious of more than a few thoughts at any one time. In fact, in a very real way, we have a limited â€Å"attentional capacity†. As we become uncomfortably stressed, distractions, difficulties, anxieties and negative thinking begin to crowd our minds. This is particularly the case where we look at our definition of stress, i. e. that it occurs when a person perceives that â€Å"demands exceed the personal and social resources the individual is able to mobilize. † These thoughts compete with performance of the task for our attentional capacity. Concentration suffers, and focus narrows as our brain becomes overloaded. As shown in the figure, this is something of a slippery slope: the more our brain is overloaded, the more our performance can suffer. The more our performance suffers, the more new distractions, difficulties, anxieties and negative thoughts crowd our minds. Other research has shown that stress reduces people’s ability to deal with large amounts of information. Both decision-making and creativity are impaired because people are unable to take account of all the information available. This inability accounts for the common observation that highly stressed people will persist in a course of action even when better alternatives are available. It also explains why anxious people perform best when they are put under little additional stress, while calm people may need additional pressure to produce a good performance. Notes on the research behind the Inverted-U: While this is an important and useful idea, people’s evaluations of stress and performance are by necessity subjective. This has made it difficult to prove the ‘Inverted-U’ idea formally. Also, for ease of explanation, we show a smooth curve here. In reality, different people have different shaped and positioned inverted-Us at different times and in different circumstances. This is all part of â€Å"life’s rich tapestry†. Entering a State of Flow When you are operating in your â€Å"area of best performance†, you are normally able to concentrate, and focus all of your attention on the important task at hand. When you do this without distraction, you often enter what Professor Mihaly Csikszentmihalyi of Chicago University describes as a state of ‘flow’. This involves â€Å"being completely involved in an activity for its own sake. The ego falls away. Time flies. Every action, movement, and thought follows inevitably from the previous one, like playing jazz. Your whole being is involved, and youre using your skills to the utmost. You perform at your best in this state because you are able to focus all of your efforts, resources and abilities on the tasks at hand. While you are sufficiently motivated to resist competing temptations, you are not so stressed that anxieties and distractions interfere with clear thought. This is an intensely creative, efficient and satisfying state of mind. It is the state of mind in which, for example, the most persuasive speeches are made, the best software is developed, and the most impressive athletic or artistic performances are delivered. Helping Yourself to Get Into Flow One of the frustrations of management is that managers can feel that they lose the ‘right’ to these periods of deep concentration when they must be readily available to others, and be able to deal with the constantly changing information, decisions and activities around them. Studies of good managers show that they rarely get more than a few minutes alone without distraction. This alone can be frustrating, and can contribute strongly to managerial stress. In jobs where concentration is a rare commodity, there are various solutions to creating the periods of flow that sustain good performance. Solutions include working from home, or setting aside parts of the day as quiet periods. Another solution might be to delegate the activities that require the greatest levels of concentration, allowing the manager to concentrate on problems as they arise, serving to create a flow of its own. One of the key aims of this site is to help you manage stress so that you can enter this state of flow, and deliver truly excellent performance in your career.

A Hydraulic Accumulator Energy Engineering Essay

A Hydraulic Accumulator Energy Engineering Essay A hydraulic accumulator is a device in which potential energy is stored in the form of a compressed gas or spring, or by a raised weight to be used to exert a force against a relatively incompressible fluid. They are used in fluid power systems to accumulate energy and to smooth out pulsations. Accumulators store energy when hydraulic system pressure is greater than the accumulator pressure and provide hydraulic energy when the accumulator pressure is greater than the system pressure. By storing and providing hydraulic energy, accumulators can be used as a primary power source. Accumulators are inherently dynamic devices, they function when configuration changes (actuators moving, valves opening, etc.) are occurring within a hydraulic system. Accumulators respond very fast to configuration changes, nearly instantaneously for gas accumulators. They are usually used in conjunction with a pump/motor in a hydraulic circuit. A hydraulic system utilizing an accumulator can use a smaller fl uid pump since the accumulator stores energy from the pump during low demand periods. The pump doesnt need to be so large to cope with extremes of demand, so that the supply circuit can respond more quickly to any temporary demand and to smooth pulsations. The capability and affect of the accumulator is determined by the overall volume of the accumulator and preload/pre-charge of the spring/gas. There are 4 types of accumulators: bladder, diaphragm bladder, piston (either spring or gas controlled) and metal bellows. The choice of accumulator to use in a given application depends on required speed of accumulator response, weight, reliability and cost. Pressurized gas accumulators will have the faster dynamic response and are reliable. Metal bellows accumulators are very reliable, but will not respond as fast as a pressurized gas accumulator. Accumulators with seals generally have the lowest reliability. Accumulators are either spherical or cylindrical in design. Bag, piston and metal bellows accumulators are cylindrical. Diaphragm accumulators may be spherical or cylindrical. Accumulators are usually manufactured into 2 halves which are either welded or threaded together. A fill port is installed at one end of a gas accumulator and the hydraulic connection fitting (with poppet valve, if required) is installed at the opposite end. For a spring accumulator, the non pressure sid e usually has a fitting that connects to the hydraulic reservoir (for seal leakage and to alleviate back pressure on a piston). Materials are usually steel, but accumulators may also be made from aluminium or a composite (filament wound) material. Compressed gas accumulators are by far the most common type; these gas accumulators take advantage of the fact that the gas is compressible. A gas accumulator has a gas pre-charge that is less than the nominal hydraulic system pressure. As hydraulic fluid enters the accumulator the gas is compressed to the nominal system pressure, which is an equilibrium position and represents the maximum amount of energy stored by the accumulator. As system hydraulic pressure drops, the gas will expand pushing hydraulic fluid back into the system. The gas pre-charge level is an important parameter for gas accumulators since the pre-charge and overall accumulator volume; determine the maximum amount of hydraulic energy that will be available to the system. The pre-charge is the pressure of the gas in the accumulator without hydraulic fluid in the fluid side. A gas accumulator is pre-charged with nitrogen gas when there is no hydraulic fluid in the accumulator to the desired pressure. The gas accumulator pre-charge is a very important variable for ensuring optimal accumulator performance and maintaining long life of the accumulator. Too high of a pre-charge pressure and the fluid volume capacity is reduced. Furthermore, if a bag accumulator charge is too high than the bag may hit the poppet valve which could damage the bag through repeated hits in service, or cause a fatigue failure in the poppet valve assembly. For a piston accumulator, the piston may be driven into the stops repeatedly affecting seals or cause a fatigue failure in the piston stop. Too low of a pre-charge pressure and the accumulator may not maintain desired minimum hydraulic system pressure. Also a low pre-charge pressure will allow a piston accumulator to repeatedly hit the up stops leading to premature failure of the accumulator. For a bag accumulator, the bag may be forced into an unnatural shape (e.g.,with folds) leading to bag damage and premature bag failure. When sizing an accumulator the pre-charge pressure is an input to the sizing process. However, once the accumulator is sized the minimum and maximum gas volumes should be computed (under worst case conditions) and analyzed to ensure piston stops are not hit or that a bag cannot fully collapse or expand completely in the accumulator. Bladder Accumulator A bladder accumulator consists of pressure vessel with an internal elastomeric bladder with pressurized nitrogen on one side and hydraulic fluid on the other side (system side). Figure 1 shows a bladder accumulator. It has 3 stages of operation: The accumulator is charged with nitrogen through a valve installed in the top. The accumulator will be pre-charged to nominal pressure when the pumps are not operating. Secondly when nominal hydraulic system pressure is applied the bag will be compressed to its fully compressed state. When the bag is fully compressed, the nitrogen pressure and the hydraulic pressure are equal. Finally as system pressure drops the bag expands, forcing fluid from the accumulator into the system. As the bag expands pressure in the bag decreases. The bag will continue to expand until the bag pressure equals the hydraulic pressure (which will be lower than nominal system pressure) or the bag fills the entire accumulator volume which is an undesirable situation. A poppet valve keeps the bag in accumulator from being pulled into the downstream tubing should the bag over-expand. If the bag was pulled into the downstream tubing, the accumulator would never recharge and normal flow from the pump would be constricted. The maximum flow rate of the accumulator is controlled by the opening area (orifice) and the pressure difference across the opening. Figure http://www.globalspec.com/NpaPics/18/146314_030520074661_ExhibitPic.JPGAccumulator, Bladder Typehttp://www.globalspec.com/NpaPics/18/146314_030520074661_ExhibitPic.JPG The main advantages of a bladder accumulator are fast acting, no hysteresis, not susceptible to contamination and consistent behaviour under similar conditions. Accumulators are easy to charge with the right equipment. Because there is no piston mass, the speed of the bladder accumulator is governed by the gas, which reacts very fast to changes in hydraulic system pressure. Hence bladder accumulators are the best choice for pressure pulsation damping. Also, the bladder attachment internal to the accumulator has proven to be very reliable in service. Of course there is always the potential for bladder failure, which is a failure that would not usually be detectable in service. Also, temperature differences on the gas will have some affect on performance. The main limitation of bladder accumulators is the compression ratio (maximum system pressure to pre-charge pressure) which is limited to approximately 4 to 1. Hence gas accumulators will be larger than other accumulators for the same flow requirements. The pre-charge pressure is typically set to approximately 80% of the minimum desired hydraulic system pressure. Diaphragm Accumulator A diaphragm accumulator is similar to bag accumulator except an elastomeric diaphragm is used in lieu of a bag. This would typically reduce the usable volume of the accumulator so the diaphragm accumulator may not have volume capacity of a bladder accumulator. A schematic of a diaphragm accumulator is shown in Figure 2. http://www.machinerylubrication.com/articles/200907/pg26b.gif Figure http://www.machinerylubrication.com/articles/200907/pg26b.gif The behaviour characteristics of a diaphragm accumulator are similar to a bag accumulator and have the same advantages and disadvantages. However a diaphragm accumulator may be spherical or cylindrical (or possibly other shapes) which may be an advantage in some installations. The main difference with bladder accumulators is an increased maximum compressions ratio (maximum system pressure to pre-charge pressure) of approximately 8 to 1. Piston Accumulator A gas piston accumulator is shown in Figure 3. A gas piston accumulator has a piston which slides against the accumulator housing on seals. On one side of the piston is nitrogen and on the other side is the hydraulic fluid and connection to the system. A fill port allows pressurization of the nitrogen. Accumulator, Piston Type Figure http://www.tobul.com/index.php?option=com_contenttask=viewid=13Itemid=27 A gas piston accumulator will not respond to transient pressures as fast as a bladder accumulator due to the mass of the piston (frequency characteristics depend on piston mass and spring characteristics of the nitrogen). However, a piston accumulator will have better damping due to hydraulic leakage (viscous damping) and friction between the piston and housing (coulomb friction seal friction). Piston accumulators may also be more prone to leakage than other types of accumulators due to the seals. Piston accumulators will generally provide higher flow rates than gas accumulators for equal accumulator volumes. This is because piston accumulators can accommodate higher pressure ratios (maximum system pressure to pre-charge pressure) than gas accumulators, up to 10 to 1, compared with bladder accumulator ratios of 4 to 1. The disadvantages of piston accumulators are that they are more susceptible to fluid contamination, have a lower response time than bladder (unless the piston accumulator is at a very high pressure) and will have hysteresis from the seal friction. The pre-charge for a gas piston accumulator is typically set to around 90% of minimum desired hydraulic system pressure. A schematic of a spring piston accumulator is shown in Figure Accumulator, Spring Type In a spring accumulator, the spring applies a force to a piston which compresses (or pressurizes) the fluid in the accumulator. As normal system pressure, the spring will be fully compressed. As system flow demands exceed the pump capacity, the spring will extend pushing the piston which in turn pushes fluid into the adjoining pipe. Hence the accumulator supplements pump flow. The maximum response time of the accumulator is set by the natural frequency, which is computed using Metal bellows accumulators are used where a fast response time is not critical yet reliability is important. Emergency brake accumulators are a good application for metal bellows accumulators. The metal bellows accumulator consists of a pressure vessel with a metal bellows assembly separating fluid and nitrogen. The accumulator is similar to a piston accumulator, except a metal bellows replaces piston and piston seals. Metal bellows accumulators are very reliable and long life components, and have a proven service history. Metal bellows accumulators are pre-charged by supplier and then permanently sealed leading to a maintenance free accumulator. Metal bellows accumulators will be slow in responding to pressure changes due to increased mass of piston and bellows. The advantages to the metal bellows type include exceptionally low spring rate, allowing the gas charge to do all the work with little change in pressure from full to empty, and a long stroke relative to solid (empty) height, which gives maximum storage volume for a given container size. The welded metal bellows accumulator provides an exceptionally high level of accumulator performance, and can be produced with a broad spectrum of alloys resulting in a broad range of fluid compatibility. Another advantage to this type is that it does not face issues with high pressure operation, thus allowing more energy storage capacity. Applications of Accumulators to KERS One of the main applications of hydraulic accumulators is storing energy. Hydro-pneumatic accumulators incorporate a gas in conjunction with a hydraulic fluid. The fluid has little dynamic power storage qualities. The fluid can only be reduced a small amount in volume even under high pressure. Therefore when only a small amount of the total contained volume is released, the pressure of the remaining fluid in the system will drop to zero. However, the relative incompressibility of a hydraulic fluid makes it ideal for fluid power systems and provides quick response to power demand. The gas, however working with the hydraulic fluid in the accumulator, can be compressed to high pressures and low volumes. Potential energy is stored in this compressed gas to be released upon demand. In the piston type accumulator the energy in the compressed gas exerts pressure against the piston separating the gas and hydraulic fluid. The piston in turn forces the fluid from the cylinder into the system a nd to the location where useful work will be accomplished. On this basis, with respect to all the types of accumulator a hydro-pneumatic accumulator would be ideal for storing the energy taken out of a bike whilst braking.. Of course the loss of pressurized gas in a sealed accumulator is a failure critical to safety when it plays such an important role as braking. A team of engineering students from university of Michigan undertook a project to use a hydro-pneumatic regenerative braking on a bicycle. It was a redevelopment of a heavier previous attempt to make a working prototype to fit within a 29 front wheel. They use a 0.5L accumulator and believed this to be sufficient in storing the required energy at a maximum working system pressure of 5000psi. They failed to test and thus supply conclusive results for the performance characteristics but through theoretical analysis they prescribe the key parameters fig. Figure Its weight is clearly impractical as it weighs almost as much as a conventional bike at 13kg. In terms of weight of a bicycle with respect to saving weight, it is more important to have lighter wheels than a lighter bike frame. This is because the rolling resistance is applied at the wheels although it carries half the overall weight of bike and rider a lighter wheel makes it easier to initially start a bike. Based on the team from michigans ( ) the following calculations outline the practicality of implementing a hydraulic KERS. Firstly for a hydraulic system to be implemented the storage must be addressed the capacity must be determined and pressures needed to store the kinetic energy. A bike braking from 20mph requires 5000J of energy to power. From Parkers website a manufacture of accumulator and motors parkers rate the ACP series accumulators at max pressure 5000psi, if assuming A hydraulic KERS must use a hydraulic motor to provide enough torque to drive the bike as well as provide enough resistive torque to be an effective brake. A bicycle travelling at 20mph on 26 wheels spins the motor through 18:1 gear ratio of the pump gear train which then spins the motor 4632rpm, corresponding to 4.52 N-m torques at 3000 psi. This translates to a braking torque of about 81.36 N-m applied to the main gear due to the 18:1 gear ratio. From this brake torque is an effective brake On release of pressure fully charged 5000 psi accumulator generates 7.57 N-m of torques. The 14:1 gear ratio of the motor gear train applies a 105 N-m torque to the main bicycle cluster gear. 7.57 N-m corresponds to around 800 rpm from its torque rpm curve, which turns the main gear at around 57 rpm due to the 14:1 gear ratio. This torque from fig can propel a bike at Conclusion The accumulator doesnt need to be an excessively large capacity to release enough energy to propel a bike 20mph, upon releasing the energy at a pre-charge of 3200psi. But a larger accumulator is needed for the accumulator to give more than one bursts using its full capacity. A hydraulic motor can produce 81.36N-m braking torque which is an effective brake. Furthermore an accumulator can power a hydraulic motor provide an accelerating torque to propel a bicycle. However based on the weight of the design from univerty of Michigan their prototype was 13kg, they used two accumulators plus they attached it to a bracket that probably contributed to the majority of the weight.

Organizational Diagnosis Plan Of Six Box Model Information Technology Essay

Organizational Diagnosis Plan Of Six Box Model Information Technology Essay The six-box model is a structure developed by the American analyst Marvin Weisbord to evaluate the performance of organizations. It is a general structure and is proposed for use across a wide variety of organizations. It is based mainly on the techniques and assumptions of the field of organizational improvement. The model represents a exacting way of looking at organizational structure and plan. It gives awareness to issues such as planning, incentives and rewards, the role of support functions such as personnel, internal competitions among organizational units, standards for remuneration, partnerships, hierarchies and the delegation of authority, organizational control, accountability and performance assessment. The model also follows the basic systems approach to organizational functioning including the well-known inputs and outputs categories. (The Marvin Weisbord Six-Box Model (Weisbords Model)) Table 1 1.0 Scope This plan provides information about Organizational Diagnosis control of XYZ. It is used to plan and implement organizational process based on a thorough understanding of the current strengths and weaknesses of the organizations processes and assets. 2.0 High-Level Overview Application Development is performed according to the phases of the Software Development Lifecycle. Below is a high-level overview. Each of these stages is described in more detail, in the sections that follow. Generally, a customer or site manager initiates a request for development based on the customers needs. The request is then analyzed to determine if it should be done as a request task or a project. If it should be a project, then it is analyzed to create a project charter. It should then be determined whether planning can be done with pre-allocated hours or whether a planning project is required. These results should be documented in the planning SOW, a planning schedule, and a PID if necessary. This can be done during by meeting with the customer depending on the scope of the project. The purpose of the planning project is to perform all of the planning and requirements analysis required in order to get an execution project approved. During the planning phase, business requirements and a project plan with all of its subordinate plans should be created. This can be done depending on the scope of the project. During the requirements analysis phase, the software requirements should be developed based on the project plan and business requirements. Then, an estimate should be created based on the project plan and software requirements. And finally, a schedule should be done based on the estimate, software requirements, and project plan. Once approved by the customer, these documents should be combined with an execution SOW. Once approved and resourced, the project and its resources are entered into the Project Lifecycle Application (PLA). Once approved, the execution project begins; and, the first phase is design. During this phase the architecture is developed and a test plan is created. The design and test plan are then reviewed and approved. Once approved, the construction phase begins. During this phase all components are created and integrated. The components will also be unit tested, integration tested, system tested, and then user tested. After construction, preparation to move the software to production is done. A Transition plan is created which is intended to train the support staff and users on the software and to coordinate its release to production. All help and support documentation should be created and approved. After the migration is complete, a post project meeting should be held to conduct lessons learned exercises. The Measurement Analysis repository should also be updated, analyzed and re-baseline when necessary. 2.1 Overview Organizational Diagnosis enables steady method routine across the organization and provides a foundation for cumulative, long-term benefits to the organization.

Essay example --

Our world is growing! Growing in population that is, but the resources are staying the same. To help with the growing of the population that will be happening in the 21st century, science and agriculture need to work hand-in-hand. They need to stand together to make a break through together, to insure that everyone will have food on their plate. We need to work to have larger yields with the land we have. Some people say that humans need to change their diet, and others say that we should destroy hundreds of acres of wild land. According to Feed Nine Billion website, people feel that the only way things will be improving, is if everyone becomes a vegetarian. But others disagree. The people who think that this is the only way do have a good point. Grains and vegetables do produce so much faster than animal production. Then again, you can’t just assume that everyone will follow, and turn to becoming a vegetarian. Besides think of all the farmers that would be out of a job! These farmers could have been family business, just like a dairy farm that is located outside of our town. R&D dairy farm has been handed down generation after generation. Funding has to become an essential in today’s society for this new advance in technology that will be needed. We aren’t only having problems worrying about feeding the next generation; we should be concerned now. Did you know, that in the last 11 years, six of those years the population has consumed more than what was produced? The Food and Agriculture Organization of the United Nations website, just this year the cereal production has gone up eight percent. Imagine what will be expected in the 21st century. People are demanding more food now, than they ever have. Scientists say that far... ...t too expensive for the farmers. The second step is that broader awareness is required. According to Sarah Alexander, â€Å"different farmers trust different sources, such as vendors, crop consultants, and university extension services.† Farmers are going to need to be open minded to new things, in order to feed the human race. The last step is farmers need the right incentives. Farmers want to know about the good that they are doing. Farmer’s want to know how they are saving the environment, and how they are producing more food, and feeding more people than they were before. If we all work together, feeding the nine will be possible, and even likely. Farmers need to know how much they are needed, for this process and know that new ways of farming will help in the long run. People don’t have to change their diets so everyone can be fed. Together, we can feed the world.

Parenting Styles: What They Are and Why They Matter Essay -- Most Effe

A parent is not only the loving mother who holds you close to her for nine months and then many years, or the dad who plays baseball with you and intimidates his daughter’s dates. It is someone who is there for you from the start, guiding you to the right path of knowledge and teaching you how to stay on the right path independently. A parent does not need to have any biological associations to the child in order to be a parent to them. A parent must have certain characteristics to be rightfully called a parent. For many years psychologists have defined ways to correctly support a child to adulthood for parents all over the world. Some people conclude their practice of parenting their children after the child reaches the age of 18, and some have the duty as a lifelong job. As years pass so do generations and media changes very constantly and plays a factor in how children act and respond to certain stimuli. There was a study done in 2009 and people in Poughkeepsie had answere d a poll that revealed overall every age group finds it harder to raise a child in today’s day and age than it had been in previous generations, but the older the parent is, the longer the generation gap would be and that factors in the difficulty of understanding how media works with a child’s psychological set up. What a child watches on a television screen is what the child will imitate through behavior. However, parenting is not a book written by a doctor, parenting is having a family, and creating memories, also ensuring that your children live in a nourishing environment for their emotional, mental, and physical health. The accepted goal of a parent is to ensure that their child or children grow to be mature and able to both support themselves and a f... ...s Correlates. ERIC Digest.

The Trip: Journey To The Center Of Terence Mckennas Inner Self. :: essays research papers

The Trip: Journey to The Center of Terence McKenna's Inner Self. Terence McKenna has become one of the most (in)famous figures in the exploration of psychedelia and its impact on society and technology. Here McKenna espouses his theories on psychedelic mushrooms, virtual reality, shamanism and evolution. This is definitely one of the strangest and most interesting articles I have ever read. At first it seems almost totally incomprehensible and inconceivable, but after reading it over a couple of times with a good dictionary and thesaurus it begins to make sense. In this article McKenna explains one of his trips on magic mushrooms. He describes this trip as â€Å"a virtual reality tour of God's cerebral cortex, hosted by the Lucky Charms leprechaun†. He then goes on to tell how this trip affected his life and how it was such a complete shock that it caused the literal turning inside-out of his intellectual universe. He was knocked off his feet and set himself the goal of understanding this. His quest led him all over the world, exploring traditions of magic-religious drug usage. In the years since his fateful encounter with the self-transforming machine elves of hyperspace, McKenna has fashioned his mental Merzbau on the New Age lecture circuit, where he has earned the benediction of the psychedelic High Priest himself, who dubbed him â€Å"the Timothy Leary of the 90's†. McKenna has written several books as well as having rave bands set his ruminations to billowing techno-trance music. The main focus of this article is on McKenna's theory, which is concocted from psychedelic Darwinism, fringe linguistics, and New Age eschatology. This theory is based on the notion that â€Å"Hallucinogenic plants may have been the catalysts

Harlem Renaissance Essay

The Harlem Renaissance was a significant event in the history of the United States of America. The Harlem Renaissance centered on the culture of African-Americans and took place at the end of the American Civil War in 1865. This era gave rise to music, art, and literature in African-American culture. Winning the Civil War meant that African American were now free and could, at their risk, go anywhere they wanted. This is when the Great Migration all started. The Great Migration was when large groups of blacks moved in Northern cities like Chicago and New York in massive numbers for jobs because the South had been victim to a crop infestation. Many of them moved particularly to a large neighborhood located in the northern section of Manhattan called Harlem, also known as â€Å"the capital of black America†. By this time, chances for employment and education were available for African-Americans, and many of them expected the same treatment and life the white Americans had be given. This was not to be the case when Plessy v. Ferguson case went to the Supreme Court and the decision had been held that racial segregation was â€Å"constitutionally acceptable†. African-Americans were heartbroken; they wanted equality and all they had been given nothing close to the life of the white Americans, not even a secure environment to live. Though they did have some rights, such as, all African-American men could vote, African-Americans, all, could receive better education, and they got better jobs, but that still seemed to be not enough. African-Americans wanted to part ways with their clingy stereotypes and define themselves as something better. They wanted to be something more than just a â€Å"negro.† The African-Americans didn’t want to be like their white suppressors, but wanted to create a new meaning to what it meant to be black. Starting in the early 1900s the African-American middle class started a push towards racial equality. W.E.B. Du Bois was the central leader of the movement. He collaborated with other African-American activists and white civil rights workers in New York to review the difficult challenges facing the African-American population. 1909 the NAACP, or National Association for the Advancement of Colored People, was found by the group working with Du Bois. This group was specifically organized to advocate civil liberties and fight for African-American rights. Although this cause was thought to be supported by all African-Americans it was not the case with Jamaica-bred Marcus Garvey. Garvey started the â€Å"Back to Africa movement,† which initially was him saying that he thought all African-Americans should just pack up and leave the states because they weren’t welcomed. Garvey founded the UNIA-ACL, or Universal Negro Improvement Association and African Communities League, which promoted the â€Å"Back to Africa†¦Ã¢â‚¬  slogan. Garvey said it was to encourage African-Americans to come together and feel pride in their roots. These groups, although not all supporting staying and fighting, helped the African-American population develop a sense of empowerment for African-Americans everywhere. The Jazz Age was an explosion of African-American culture into music. Just at the end of WWI, there was an economy boost and a change in society. During this time Americans started to relax and take up hobbies. The Prohibition had just been ratified, although it didn’t ban alcohol it made it extremely difficult to get, legally. That is when alcohol clubs, called â€Å"speakeasies† were created. â€Å"Speakeasies† gave Americans the chance to socialize with other, engage in drinking, and go against traditional culture. Some might have even called them Modernist. There was a certain speakeasy in Harlem called the Cotton Club. It’s them as the look of a plantation in the South. They only allowed African-American musicians to play there and only allowed white Americans, with some exceptions, wine and dine there. One talented jazz musician would be Duke Ellington. Ellington was a wiz at playing the piano; he actually played at the Cotton Club from for four years. His band stomped to theatricality routines in numerous shows. Forms of art gave some African-Americans a break from reality. Artists painted things from African-American nightclubs, to African-American toiling in the fields. Aaron Douglas was a famous artist whose work exercised the ‘New Negro’ idea. The ‘New Negro’ idea correlated with Dubois idea of â€Å"twoness† idea, which meant the finding of one’s individuality with a divided awareness of one’s identity. Douglas painted murals, building, and created illustrations for many African-American books. In 1940 Douglas moved to Nashville and founded the Art Department at Fisk University and taught for twenty nine years there. Douglas said, â€Å"†Ã¢â‚¬ ¦Our problem is to conceive, develop, establish an art era. Not white art painting black†¦let’s bare our arms and plunge them deep through laughter, through pain, through sorrow, through hope, through disappointment, into the very depths of the souls of our people and drag forth mat erial crude, rough, neglected. Then let’s sing it, dance it, write it, paint it. Let’s do the impossible. Let’s create something transcendentally material, mystically objective. Earthy. Spiritually earthy. Dynamic,† which means, let’s make something incredible out of tragedy. Writing also became a major step forward in the Harlem Renaissance, especially since during this time most African-Americans were illiterate. African-American writers talked about the past of black culture. They wrote about slavery and the effects it had on society today, etc. Common themes of these books ranged from alienation, to wanting to be individual. The most famous African-American writers include: Langston Hughes, Sterling Brown, and Zora Neale Hurston, just to name a few. Zora Neale was a novelist, folklorist, and anthropologist. She believed in the motto, â€Å"I want a busy life, a just mind, and a timely end.† Zora wrote to preserve African-American traditions and to contribute to new literature. Langston Hughes was a writer who collaborated with Hurston and other artists in his book of poetry entitled The Weary Blues. Hughes also wrote an essay called â€Å"The Negro Artist and the Racial Mountain,† where he told people what he saw as ‘mountains’ facing African-American writers. In his essay, Hughes mentions a young poet he spoke to and says how the poet wanted to be known as a poet, rather than a â€Å"Negro poet,† which is clearly understandable since there was still racial tension during this time. In conclusion, the Harlem Renaissance was a major event in the history in the United States of America because it brought a culture together using simple things, like music, art, and literature. If it had not been for the Harlem Renaissance, who knows what might’ve happened to the African-American culture, where it might’ve been at this point in time without the occurrence of the Harlem Renaissance. It brought together a race that has, over the years, been beaten, cursed at, talked about, and slaughtered for the comfort of others, and just a simple melody of a song was able to bring them closer together after being ripped apart.
