The Greenhouse Effect Argumentative Essay Example For Students

The Greenhouse Effect Argumentative Essay The Greenhouse EffectThis essay is going to describe what the greenhouse effect is andwhat it does.It is also going to say what causes the greenhouse effect and theconsequences of it. What is meant by the term the greenhouse effect is that the heatfrom the sun comes into the Earths atmosphere and cannot get out so becomestrapped.It gets its name because this is very much like a greenhouse.This effectoccurs as the incoming short wave radiation is changed when it hits the Earthssurface into long wave or infra-red radiation.Heat energy in this form is thenabsorbed and stored in water vapour and carbon dioxide in the atmosphere. We will write a custom essay on The Greenhouse Effect Argumentative specifically for you for only $16.38 $13.9/page Order now Many different things cause the greenhouse effect. The amount ofcarbon dioxide in the atmosphere is increased by 0.4 percent each year becauseof the massive consumption of fossil fuels such as oil, coal, and natural gas. Another contributing factor is the the amount of forest logged, every second ofthe day the area of a football field in trees is cleared by either being loggedor burnt. Two other deadly greenhouse gasses which are entering the atmosphereeven faster than carbon dioxide are methane and chloroflourocarbons, althoughthey are not as damaging in the long run. These increases are likely to affect worldwide temperaturesdramatically. In 100 years time the average temperature for most parts of theworld will increase from between 2C to 6C if greenhouse pollution continues atits present rate. This temperature increase would drastically affect the growthof many different crops and cause the polar ice caps to melt, thus increasingsea levels to rise up to several metres. If this rise in sea level was to occurmany areas would be much more prone to flooding, and generally much deeperfloods than would be expected nowdays. This flooding would happen paricularlyaround coastal regions worldwide, and also along many rivers that flow to orfrom coastal inlets. The greenhouse effect is very important because it leads to risingwater levels and temperatures which can have a large effect on the worldsclimate.Changes in the climate can lead to significant changes in agriculturalindustries.This can lead to good farmland becoming deserts, make it too hot forsome crops to grow or let pests and diseases thrive.As a result some countriescan suffer bad economic conditions and people will have to move.Some low lyingcountries such as those on the Pacific islands or Holland could have a lot offlooding and a lot of money would need to be spent building sea walls and leveebanks to stop flooding.For these reasons it is very important to carefullymanage the greenhouse effect by reducing the amount of carbon dioxide going intothe air and planting more trees.

The Occupy Wall Street Movement Moral and Economic Issues

The Occupy Wall Street Movement Moral and Economic Issues Introduction One of the critical socioeconomic developments in the United States in this decade is the Occupy Wall Street Movement (OWM). The main question that is posed by people at the mention of the Occupy Wall Street Movement is the course that was being pursued by theAdvertising We will write a custom essay sample on The Occupy Wall Street Movement: Moral and Economic Issues specifically for you for only $16.05 $11/page Learn More Movement and the nature of activities that marked the pursuance of social and economic issues. The Movement sought to streamline the social and economic state of affairs in the United States. In this paper, it is argued that the Occupy Wall Street Movement was a purely socioeconomic movement that sought to advance the moral and ethical issues that were imminent in the US economic environment. This paper explores the Occupy Wall Street Movement. The paper brings out the critical moral issues of the Movement and its implications on the economy. This is followed by a theoretical analysis of the implications of the Movement using ethical models like utilitarianism, virtue ethics and the Kantian ethics. Moral and economic implications of the OWM It is critical to bring out the reason that led to the birth of the Movement to understand the moral issues that informed the Movement. The OWM refers to the protest that began in the year 2011, on the 17th of September. The protest took place in Zuccotti Park in the Wall Street Financial Street in New York. The protest was initiated by Adbusters, A Canadian Group and magazine, together with the public relations Workhouse based in Manhattan. The protest later spilt to other cities, thereby attracting more protesters. The protest came after the period of financial uncertainty in the United States, where numerous people had been subjected to the impacts of the financial crisis. According to the protesters, the financial and the economic crisis in the country had resulte d from the exploitation of the economic systems by the profiteers, who failed to pay attention to the broader needs of all the citizens. Instead, they focused on expanding their profits at the expense of the economy of the United States. The Occupy Wall Street Movement carries a similar moral message, just like other movements in the world (Moore, 2011). Among the potent implications of the protest was that it resulted in the end of a decade of economic depletion in the United States. It is argued that the misfortunes of the United States economy began in the same street in which the protest movement began.Advertising Looking for essay on business economics?

Others are the unsustainable management of corporate firms in the country and the worst economic recession since the 1930s recession, and the deficit in the US budget and unsustainable tax cuts. Corporate firms had grown in influence and had a lot of influence on the political institutions in the United States. An example that can be given at this point in time is the ‘too big to fail syndrome’, where large corporations were being cautioned from collapsing amidst the global financial crisis. All these issues pointed to the existence of economic injustices in the country. Most Americans felt that the economic system of the country was proving to be unfair and oppressive to them. The economic oppression was highly witnessed by the low income earners in the United States. Monetary insolvency and the growth in wealth disparity was the order of the day, which caused the protesters to occupy the Wall Street (Occupy Wall Street, 2012). The Wall Street Movement was financed by donors; people with incomes that ranged from 50,000 dollars to 100,000 dollars. The increased cost of sustaining the movem ent was one of the main problems with the Movement since sustaining the stay of the protesters in the Wall Street was an extremely expensive affair. As the financing became problematic, the protesters were forced to do away with some basic needs. In the protest camp, a substantial number of crime incidences were reported. Among the incidences included sexual assault and theft. There were also cases of police arrests and lack of protection of the protesters by the police (Occupy Wall Street, 2012). Analysis of the Implications of the OW: Utilitarian, Kantian and Virtue Ethics Terrall (2007) observed that one of the philosophies that are used in the explanation of ethics in movements is Utilitarianism. In weighing the OWM against the utilitarian philosophy, it is critical to look at both the actions and the impacts of the actions. One of the main arguments in the utilitarian philosophy is that the rightness of an action is determined by the amount of pleasure that is derived from enga ging in that action. The opposite of this statement is, therefore, true according to the proponents of utilitarianism. The OWM was a large movement that had a lot of challenges.Advertising We will write a custom essay sample on The Occupy Wall Street Movement: Moral and Economic Issues specifically for you for only $16.05 $11/page Learn More The Movement began well, with more people joining the movement as the days progressed. The most critical thing about the Movement is that it was sustained for several weeks. However, there are other questions that are raised over the problems that were encountered by the protesters and whether the Movement can be termed as a success. As noted in the preceding part of this paper, the protesters in the Movement encountered a lot of challenges, something that denotes the loss of pleasure. There are a number of economic reforms that have been made as a result of the Movement. Nonetheless, the main question here concerns the possibility of sustaining the reforms in order to address all the demands of the protesters. The protestors also embraced economic equality, which denotes the greatest good for the population (Hinman, 2012). According to Terrall (2007), the Kantian philosophy propagates the principle of morality, thus the moral duty of the person engaging in an action is quite critical. The worthiness of an action, therefore, does not depend on the results of the action, but it relies on the level at which the moral obligation bestowed upon the doer of the action is fulfilled. The OWM can be likened to the Kantian philosophy by basing on the fact that the Movement was well organized. The protesters did not largely engage in heinous acts, which could have implied the loss of morality. The protesters were highly organized and highly embraced the course for which they were pursuing, in spite of facing numerous challenges. However, there were a number of reported cases like sexual defilement and theft in the protest camps, which denotes a lack of morality. Nonetheless, the scale of such problems was quite low given that the number of people who participated in the protest was quite high. Conclusively, this movement can be highly attributed to the Kantian philosophy, especially deontology ethics (Hinman, 2012). The virtual ethics theory focuses on shaping of characters of individuals in order to encourage individuals to do the right things rightly. Among the traits that ought to be embraced by individuals include generosity, love and courage to pursue the course. Individuals ought to be moulded in time so that they can do the right things (Terrall, 2007). A look into the movement denotes a high level of discipline among the protesters, which implies the articulation of virtue ethics. Income inequality and the distribution of wealth in the United States The income disparity in the United States has been the subject of a substantial number of economic commentators. The income dispar ity has been increasing with time. The financial crisis that was faced in the US is to a larger extent likened to the income inequality in the country.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More Several reasons are attributed to income inequality in the US. Among the reasons is the absence of mechanisms of social mobility. This implies that the class issue cannot be done away with easily. Most of the people in the country, therefore, fall in the middle wage category. The stagnation in the middle class wage has persisted, thereby widening the income disparity (Ryscavage, 1998). According to Ryscavage (1998), most of the wealth in the country lies in the hands of a few individuals. Amassing of wealth by the few individuals prevents people from the middle and lower classes from climbing up the socioeconomic ladder. The few rich, therefore, get richer, while people in the middle and lower class slide down the social ladder. The other issue that has compounded the income disparity in the United States is the increase in the number of immigrants. Most of the immigrants have low skills; therefore, they work for lower wages than the set minimum wage. Income inequality and the distr ibution of wealth have been growing gradually. The problem has been speeded up by the growth in the population, which denotes a reduction in the number of job opportunities. Most of immigrants are, therefore, forced to take up low wage jobs for sustenance purposes. Monetary policies such as a rise in the rate of savings have encouraged the broadening of the income gap (Coibion, Gorodnichenko, Kueng Silvia, 2012). Way Forward A number of suggestions have been put forward to explain how the OWM can acquire an equitable outcome. One of the suggestions points to the fact that it is critical to pay attention to the underlying causes of inequality in the US. Among the underlying issues that ought to be checked is the improvement of the education system so that the young population can be more creative and craft their own jobs. Creative thought is vital to innovation in the economy and the improvement of earnings in the economy (Norton, 2011). There is also need to pay attention to the vi ces in the society, like corruption and greed. These vices are an impediment to the stabilization of the social system. Extreme capitalism should be discouraged. Future of OWM The momentum with which the OWM started has significantly gone down. However, it is important to note that the Movement has had significant impacts beyond the United States. The United Kingdom and Canada are examples of countries in which the Movement is taking place. As long as the inequalities are still prevalent in the economy, the Movement will keep having significant influence (Hinman, 2012). Conclusion The Wall Street Movement is one of the forces that have necessitated alertness in terms of the issues of economic inequality. If the government pays less attention to the movement, the magnitude of the movement is bound to rise, just as the recent uprisings in the Arab world. The demands of the movement point to the need for radical reforms in the economic system to attain a balance in the economic system. References Coibion, O., Gorodnichenko, Y., Kueng, L., Silvia, J.

Why did the caliphate collapse during the ninth and tenth centuries Essay

Why did the caliphate collapse during the ninth and tenth centuries - Essay Example Sunni has since sustained avowedly professing faith of Muhammad and it was one big blow upon another Islamic sect in Persia, this act is similar to the one that took place in the Roman Empire. Despite the presence of discernment present in Muhammad, he lacked insight in the leader who will succeed him after his death.1 Despite Muhammad’s effort in making caliph grow, he did not prepare Ummah for its continuation after his death. The community did not believe Muhammad had passed away and did not know the person to take over and fill the role of Muhammad, Ali who was Muhammad’s son-in-law was recommended by some people to succeed Muhammad. First successor after the death of Muhammad was Abu Bakr whose roles were more secular as compared to playing a religious role. Abu Bakr encountered cries that were based on the people’s psychology, religion, political and from other nations. He managed to make Islam a world force although during his time, the Islam participated in Apostasy war, which was because of dispute between Makkan emigrants and Ali Bakr’s supporters. During the war, many people died including those who were recognised for the compiling of Quran. Compiling Quran was the biggest achievement of Abu Bakr as compared to other encounters such as the apostasy war. There was a systematic employment of slave soldiers, which was one major innovation that characterised many Muslim regimes.2 Caliphate Umar gave people determination, especially in participating in the Jihad; hence, he wanted to continue conquests that were set by Abu Bakr, targeting Persian Empire and the Byzantime. Caliphate Umar took part in the Damascus conquest including the conquering of Saida. He was responsible for fixing many Islamic traditions including the Muslim calendar. Uthman succeeded Umar and he had both practical, intelligent military and political leadership style. Moreover, Uthuman faced opposition from other Muslims

The Death Penalty in the United States Essay Example | Topics and Well Written Essays - 2500 words

The Death Penalty in the United States - Essay Example One of the main arguments for the death penalty is that it deters crime. The death penalty is a harsh punishment as it condemns one to die hence a rational human being would rather avoid committing such an offense for fear of death. It instills fear in potential criminals, therefore, making them avoid the crime and a result, murder rate declines. A research carried out by the University of Colorado on the relationship between executions, pardons, and homicides in 2003 revealed that for each additional execution deterred five murders while each commutation reduced deterrence and produced five additional murders. This shows that punishment by the death penalty is more effective in deterring crime. However, opponents would argue that death penalty has no effect on crime since those regions which have long abolished death penalty such as the south have lower crime rates than those currently using it. Assuming they are right, this justifies death penalty as a deterrence for crime as it me ans those areas have high rates of crime hence death penalty is needed. Moreover, the variations may be caused by other factors such as educational level and economic prosperity of such regions which has a direct relation to the crime rate. For example, according to Banner, people of the south originated from violence prone areas and wealth was unevenly distributed hence at the initial stages they were using the death penalty to deter all sorts of crime. Another argument in support of crime deterrence is that death penalty incapacitates offenders. ... This shows that punishment by death penalty is more efficient in deterring crime. However, opponents would argue that death penalty has no effect on crime since those regions which have long abolished death penalty such as the south have lower crime rates than those currently using it. Assuming they are right, this justifies death penalty as a deterrence for crime as it means those areas have high rates of crime hence death penalty is needed. Moreover, the variations may be caused by other factors such as educational level and economic prosperity of such regions which has direct relation to crime rate. For example, according to Banner (6), people of the south originated from violence prone areas and wealth was unevenly distributed hence at the initial stages they were using death penalty to deter all sorts of crime. Another argument in support of crime deterrence is that death penalty incapacitates offenders. The death of a first-degree murderer means fewer crimes will be committed a s the individual is not able to commit the crime again. Cassell (183) noted that a murderer who had been convicted and given a death sentence but escaped when the state abolished death penalty committed more of such crimes thereafter such as rape and murder. If he had been hanged, those crimes against innocent citizens would have been avoided. However, opponents advocate for life imprisonment without parole to enable the offender to get rehabilitated and change hence reduce crime (Guernsey, 2010). Walker (10) argues that contrary to popular belief, death penalty is justified in the sense that according to public opinion, many citizens of US even in states where death penalty was abolished are in favour of it as a punishment

Health assessment of newborn paper - Essay Example In addition, a child that is not breastfed is 15times more likely to die than breastfed children (Jones 2013). In later life, it is perceived that adults who were effectively breast fed have a high IQ than adults who were provided with formula. The IQ is more advanced if the adult was breastfed for a long period. Jones (2013) is of the assumption that children who are breastfed for a long period have a less probability of obesity in adulthood. The information should be provided to the mother during the child’s clinical visits. In addition, the health practitioner should also highlight the benefits of breast feeding to the mother. To enhance the understanding of the mother, the practitioner should provide the American Academy of Pediatrics and the American Dietetic Association as recommendation sites. From the sites, the mother will effectively understand the benefits of breastfeeding. Ssemukasa, E. & Kearney, J. (2014).

Parasite-Induced Changes in Host Behaviour

Parasite-Induced Changes in Host Behaviour Parasite-Induced Changes in Host Behaviour: Is it Truly Parasitic Manipulation? Introduction Behavioural changes in the host when infected with a parasite were first observed in 1952, when van Dobben discovered that fish caught by cormorants (waterbird) were more likely to play intermediate host to the cestode, Ligula intestinalis than fish caught by fishermen (cited in Thomas et al., 2005). However it wasn’t until 1972 that the ability of parasites to manipulate their host’s behaviour in order to facilitate their transmission was discovered and demonstrated by Holmes and Bethel (cited in Poulin, 2000). They showed that infection of the parasite, Polymorphus paraoxus caused the amphipod, Gammaeras lacustris to display abnormal behaviours that led to an increase in its predation by ducks, the definitive host of the parasite. Since then there has been considerable research carried out in this area supporting the idea that parasites have adapted in order to manipulate their host, with a large number of parasites now known to cause changes to their hosts behaviour. There is a wide array of influenced behaviours from anti-predator behaviour e.g. mice infected with the tapeworm, Taenia crassiceots show no stress response to predation (Wheat, 2009); to reproductive behaviour e.g. female mice infected with the nematode, Trinchinella spiralis show inhibition of their sexual behaviours, limiting possible mate response (Kavaliers et al., 2000). In a few cases completely new behaviours in infected hosts have been observed, for example orb-weaving spiders infected by a parasitic wasp build unusual webs that are designed to protect the emerging larva once the host spider dies (Eberhard, 2010). More recently, the idea of parasitic manipulation has come under criticism, due to the lack of supporting evidence demonstrating that these behavioural changes provide parasites with a fitness benefit (a prerequisite of an adaptive trait), either in the form of increased transmission or survival (Poulin, 1998) and has therefore been suggested that the observed ch anges may just be an inevitable consequence of infection, or in some cases mediated by the host itself in order to counteract the negative fitness effects of parasitic infection. Understanding the origin of these behavioural changes is of great importance as there are many manipulative parasites that have implications for human health, such as malaria which alters the behaviour in the mosquito in order to increase transmission to humans (Lynch et al., 2014) and Toxoplasma gondii which can alter the personality of infected individuals (Worth et al., 2014). Manipulative parasites are also seen as playing as important a role as predation in shaping biological communities, even having an influence on non-host species (Hatcher et al., 2014). Adaptive vs. Non-adaptive Behavioural Change The argument that some of the previously observed behavioural changes of the host during parasitic infection are non-adaptive and just a consequence of infection generally refers to three different kinds of phenomena (Thomas et al., 2005). The first is the idea that the behavioural changes are just a side-effect of parasitic infection and confer no adaptive value for either the parasite or its host. However this is a questionable explanation as it is highly unlikely that any such change in behaviour will not provide a positive effect for either organism. Therefore this explanation should only be used if there is strong supporting evidence and not used as a default explanation, for example the parasitic cestode, Hymenolepis diminuta was shown to cause reduced fecundity in females of the beetle intermediate host, Tenebrio molitor and was seen as a side-effect, until further research discovered that the parasite produced a substance that inhibited vitellogenin uptake (Moore, 2012). Seco ndly some behavioural changes may be considered beneficial to the parasite, but are not due to manipulation by the parasite in order to do so, for example when the parasite Ligula intestinalis infects the Roach (Rutilus rutilus) a change in host migration to areas where predation by the parasites definitive host, ichtyopahgous predatory birds, are more common is observed (Loot et al., 2001). However it was found that these areas are more productive and it is therefore more likely that the increased energy demands caused by the parasitic infection had caused the Roach to migrate to these areas in order to negate this negative effect of the parasitic infection and increase its own fitness. Thirdly other adaptations by the parasite may have coincidentally caused behavioural changes in the host which unintentionally led to an increase in the transmission of the parasite to its definitive host, for example Fathead minnows (Pimephales promelas) are commonly infected by the trematode, Orni thodiplostomum ptychocheilus which caused a reduction in behaviours associated with host vision by the encystment of the parasite in the optic lobes, which leads to an increase in its predation by piscivorous birds. However this encystment in the eye may originally been favored by selection as it offers the parasite protection from the host’s immune system and not because it increased the transmission of the parasite to its definitive host (Shirakashi and Goater, 2005) On the other hand the argument for the adaptive nature of behavioural changes of the host during parasite infection is normally supported by the idea that it should show some degree of specificity in the intermediate host, for example P. laevis induces various behavioural and physiological changes in the crustacean amphipod, Gammarus pulex, such as altered drifting behaviour, altered anti-predator behaviour, partial castration and lower immune activity. These changes are not observed in Gammarus roeseli a closely related species, showing that the alterations by the parasite are specific to Gammarus pulex (Lagrue et al., 2007) Examinations on the effect of the acanthocephalan parasite, Moniliformis moniliformis on the behaviour of different species of cockroaches by Moore and Gotelli found that different behavioural changes had evolved for different species of cockroach supporting the adaptive nature of the host behavioural change (cited in Poulin, 1998). Indirect methods have also be en used to demonstrate the adaptive nature of altered behaviours in the host by determining whether the timing of observed behavioural changes coincide with the period when the parasite is infective to its next host. For example Tribolium confusum beetles infected with the nematode, Protospirura muricola only show observable changes in the behaviour of the beetles that make them more vulnerable to predation when the parasite has developed to the third larval stage. No behavioural change is observed in beetles home to the first and second larval stage. (Schutgens et al., 2013) Behaviour as a Form of Host Defense Not all changes in behaviour can be attributed to the manipulation of the host by the parasite as they do not benefit the parasite. The host is under selection to avoid parasites, and when possible to compensate for the negative effects of infection. Behaviour is often used in order to achieve this and is the first line of defence against parasites as it allows animals to avoid becoming infected in the first place (Moore, 2012). Animals may avoid infection by parasite propagules through behavioural means such as territoriality, site-specific defecation and mate selection. More drastic measures may be taken when trying to avoid ectoparasites, including migration, shifting habitats and lethal combat e.g. howler monkeys invest a significant proportion of their energy to slap at flies, and execute over 1500 slaps in a 12 hour resting period. Once a host becomes infected with a parasite, its behaviour will also be altered in order to minimise damage caused by the parasite. For example ani mals display sickness behaviours e.g. fever and behavioural chills, which may help in obtaining the benefit of increased care from other members of a group/population. Some animals, for example Chimpanzees, show self-medicating behaviour in which infected animals may consume medicinal plants that are not part of their usual diet. It is also possible in some cases that both parasite and host are shown to benefit from a change in host behaviour, in these cases it can be difficult to determine which organism is responsible for change, or whether it is a shared adaptation, for example caterpillars of several butterfly species play host to braconid wasp parasitoids and unlike non-parasitised individuals they perch at the top of high branches. It has been suggested this benefits the host by making itself more likely to eaten by a predator, killing both the parasitoid and host, but protecting its nearby relatives from the parasite. However it may also help the parasite by reducing the risk of hyperparasitism and therefore increasing its chance of survival. (Poulin, 1998). Conclusion Up to this point mainly laboratory based studies have been carried out in order to assess host behavioural changes due to parasite infection. Future research into the area needs to include field based studies in order to fully assess these changes in the natural environment. Currently very little is known about the molecular and genetic mechanisms underlying these changes. Therefore the basis as to how parasites cause these behavioural changes in there host is an area that needs to be addressed in order for these behavioural changes to ever be fully understood.

motivation :: essays research papers

There are several Organizational Behaviors that can be attributed towards how successful a company or one in a company will be. I have decided that the two most important elements are the motivational behaviors and the stress factors. The reason I have chose these are that someone that is motivated and can deal with stress in positive ways will be a success. Also when a corporation can motivate its employees and helps them deal with stress they are usually successful as well. Stress is a very serious problem, and can be affiliated with many fatal conditions. Stress can also be put into positive use by the correct individuals. Eustress is stress at normal healthy levels and will be prevalent in motivated individuals. In emergencies eustress can be used to enhanced focus and give a burst of energy. Eustress also has other positive effects such as cardiovascular efficiency and increased arousal. In the Japanese workplace there is too much stress and is causing somewhat of an epidemic. Yearly about 30,000 workers die from a condition known as "karoshi†, which is when they literally work themselves to death. Although in America the stress levels haven’t become an epidemic some surveys show that about 75% of American workers consider their jobs stressful. There are several factors that contribute to these high stress levels. At the moment the way the world is becoming globalized and how America is in an economic recession that is causing downsizing are considered the two biggest stressors. The downsizing is not only because of the recession but a common trend in business is to hire less then adequate number of workers then working them to their full potential or even beyond their full potential. Another problem that causes a lot of stress is known as â€Å"a square peg in a round hole†. This is when an individual is in a position that does not fit their personality. An example of this is someone such as an extrovert working a position that is better suited for an introvert. Sometimes one personality may not fit what they are doing at work and will be more successful in a different position. This is something many managers ignore so if someone wants to change their job they have to do it themselves.

High School Student And Adulthood Essay

â€Å"The power which resides in him is new in nature, and none but he knows what that is which he can do, nor does he know until he has tried.† Understanding Defines Change Psychologists Scott Scheer, Stephen Gavazzi, and David Blumenkrantz undertook a comprehensive review and analysis of the psychoanalytic literature that discussed the rites of passage in adolescence; from the reading, they derived two truths concerning an adolescent’s rite of passages. Primarily, as Scheer, Gavazzi, and Blumenkrantz state, â€Å"Not all transitional events necessarily indicate the occurrence of life transitions† (1); however, â€Å"It is believed that both cognitive interpretation and integration are required before the event genuinely becomes a significant transition or rite of passage† (1). Essentially, to label a singular event as one that ignited a life transition, one must understand the resulting effects of the event. Additionally, according to Scheer, Gavazzi, and Blumenkrantz, the event that marks the end of the transitional period between adolescence and adulthood defines the rite. Principally, a singular event cannot accelerate one’s progression into adulthood without one realizing the effects or changes that the event caused. In â€Å"Self-Reliance† by Ralph Waldo Emerson, Emerson described the idealistic depiction of the Romantic hero’s rite of passage. Emerson states that â€Å"The power which resides in him is new in nature† (1), and he believes that a person should seek the meaning of that power for himself. Emerson’s statement that one doesn’t know the power that they have until one finds it (1) falls directly in line with Scheer, Gavazzi, and Blumenkrantz’s interpretation of one’s rite of passage. Scheer, Gavazzi, and Blumenkrantz postulate that one cannot arrive at adulthood without first understanding a transitional event. Similarly, Emerson reveals, in the quote at the top of the page, that one does not know his unique power until he has tried to find it himself. Likewise, if one didn’t find their unique power, based on the definition given by Emerson, one hasn’t successfully arrived at that â€Å"Time in a man’s education† (1), and, thus, has not successfully completed a rite of passage. Therefore, Emerson views rites of passage as events that are intrinsically bound to understanding, and without cognitive interpretation, an event cannot allow one to find one’s unique power, disqualifying it as a rite of passage. The idea that rites of passages are dependent upon cognitive understanding holds true throughout a number of literary texts. For instance, in Walden by Henry David Thoreau, Thoreau details the rite of passage of a king’s son. As Thoreau states, â€Å"One of his father’s ministers having discovered him, revealed to him that he was, and the misconception of his character was removed, and he knew himself to be a prince† (72). Like Scheer, Gavazzi, and Blumenkrantz’s postulated, the son’s discovery alone did not result in the personality transition from that of a forester’s child to a prince. Instead, the son had to realize that he was, in fact, a prince before the transition could completely take effect. Thus, for one to totally embark and complete a rite of passage or a life transition, one must understand the effects of a singular event.

On the other hand, Ghazi et al. (2010) described the motivation as the voluntary forces that give an individual the will to develop direction, arousal, and persistence of goal-directed towards achievement of success in second language acquisition. In addition, they believe that motivation acts as a driving force that compels, energizes and prompts an individual to develop interest in a second language learning within a particular time in which focus is set on attaining a specified goal. Rubenfeld et al. (2007) describe the motivation as self-determination, which drives an individual’s motives towards their goal pursuits as inspired by either intrinsic or extrinsic aspirations. More so, the goals that drive an individual’s motive is aimed at attaining both the basic and psychological needs that later on leads to external approval and rewards (Dekker & Fischer, 2008). As a result, students undertaking English learning, as their second language in their studies derive their motivation from extrinsic goals.
