Effect Of Exercise On The Human Body Physical Education Essay

Effect Of Exercise On The Human Body Physical Education Essay The increase in the prevalence of obesity has seemed to lead to an increase in the trend of healthy eating and exercise over the years (Flegal, Carroll, Ogden Johnson, 2002). Interestingly, exercise is actually considered a form of stress, as it is a disruption of homoeostasis (Plowman Smith, 2011, p.22). Exercise is defined as a single acute bout of bodily exertion or muscular activity that requires an expenditure of energy above resting level and that in most, but not all, cases results in voluntary movement (Plowman Smith, 2011, p.705). When we run our heart rate rises, our muscles move faster, our respiratory rate increase, and so on. When we lift weights our muscles are pushed to work harder either via repetition and sets or the amount we lift. During these time periods, our body is struggling to maintain homoeostasis; a healthy form of stress that can make the human body more efficient and productive. Exercise will affect each system differently and different exercise will affect the different systems differently. It is said that health-related physical fitness is composed of components representing cardiovascular-respiratory endurance, metabolism and muscular fitness (Plowman Smith, 2011, p.22). In other words, the main systems that are affected by exercise are our cardiovascular, respiratory, and muscular systems. Exercise also affects our metabolism, which is not a system on its own; however is a key component to provided energy for our body. When we exercise, we need energy. Therefore energy production, or metabolism, is affected by exercise. Metabolism is defined as the the total of all energy transformations that occur in the body (Plowman Smith, 2011, p. 27). To make adenosine tripohophate (ATP), the bodys form of energy, from the food we consume we use a process called cellular respiration. Our resources included carbohydrates, triglycerides and amino acids. Through carbohydrate metabolism, we are able to break down carbohydrates into glucose or glycogen. From there our glucose or glycogen will go through the process of glycolysis to make pyruvate or lactic acid. The acids then become acetyl coenzyme A, which would then go through the Kreb cycle and the electron transport system to create ATP. From our carbohydrate we get a range of thirty to thirty-three ATPs; depending on the muscle group and if glucose on glycogen was used. With triglycerides, we must break it down into fatty acids and glycerol. The fatty acids t hen go through the process of beta oxidation to create acetyl coenzyme A. The number of ATP formed depends on the number of carbon pairs found in the triglyceride. Amino acids make about ten to fifteen percent of our energy supply; and therefore are used as a last resort (Plowman Smith, 2011). During exercise, the goal of metabolism is to do three things. First, increase mobilisation and usage of the free fatty acids in adipose tissue and intramuscular stores. Second, decrease the amount of glucose sent to muscles that are not being used while still sending some to our nervous system; particularly our brain. Third, increase the breakdown of glucose stores in the liver and muscles. This creates glucose from non-carbohydrate sources (Plowman Smith, 2011). We used a different source of energy depending on the type of exercise. If the duration of the exercise were to decrease and or if there is an increase in intensity then carbohydrates would become our main source. However, if we increased our duration and decreased our intensity the many sources would be triglycerides. When the duration is longer than an hour that is when amino acids make a small contribution to the energy production. The effects of exercise on our metabolism, in turn, affect the efficiency of other systems in the body, such as the respiratory system. While exercising, one of the first things we mentally note is a change in is our Respiratory System. This is quite simply because of the high demand for energy, exercise creates. Our respiratory system is used to provided energy via aerobic metabolism, in other words, it brings in the oxygen we need to create ATP. Therefore, it makes sense that we breathe more frequently to help our body get the energy it needs. To speed up the process, it would be best if the rate at which oxygen disassociated from haemoglobin increased. This is exactly what happens. Here is how: as we create more energy the waste product, carbon dioxide, also increases. Therefore our partial pressure of carbon dioxide increase; and because of the carbonic acid-bicarbonate buffer system, there is also a decrease in the pH levels (Martini, Ober Nath, 2012). There is also an increase in body temperatures, which is a byproduct of energy production. These conditions increase the rate of dissociation of oxygen from the protein haemoglobin. What is interesting is our misconception with the idea of our respiratory system as a limiting factor. The phrase, I am out of breath, is commonly heard by runners and gym goers. However, our level of respiratory activity is almost equal to the rate of work being done. If we take our increased activity into hand and our respiratory systems large reserve, we find that the respiratory system does not limit our ability to exercise in any way (Plowman Smith, 2011, p.385). We do not see many adaptions in the respiratory system as a result of training. As a stressor, exercise does not stress the limitations of the respiratory system; and as a result, we do not see any long or short term changes. There are some changes in the respiratory system as a result of water based exercises. We find that they have a higher lung volume and capacities. The reason for this is unknown. However, there is a theory that swimmerà ¢Ã¢â€š ¬Ã‚ ¦breath against the resistance of water, using a restricted breathing pattern with repeated expansion of the lungs to total capacity (Plowman Smith, 2011, p.305). Swimmers also do work in the horizontal position; a position optimal for perfusion of the lung and diffusion of respiratory gases (Plowman Smith, 2011, p.307). In swimmers, we also find that there is a report of higher diffusion capacity. This is also seen in runners. However, this is more likely due to circulatory changes. A slight increase in our minute ventilation is also seen as a result of training adaptation. Minute ventilation or minute volume is defined as the amount of air coming into and leaving the respiratory system per minute (Martini, Ober Nath, 2012). It is the components of minute volume that we see the change in, which affects the minute volume. Minute volume equals to how many breaths we take per minute times our tidal volume. Our tidal volume is the amount of air you move into or out of your lungs during a single respiratory cycle under resting conditions; in other words, it is quite breathing (Martini, Ober Nath, 2012, p. 739). With exercise, our tidal volume adapts and increases at rest. Therefore, individual who frequently exercise  will develop a large tidal volume. As a result, the minute volume is higher after training than before, allowing for the ability to increase our endurance (Plowman Smith, 2011). Besides these changes, we do not see a lot of long-term adaptations in the respiratory system as a result of exercise. The changes mentioned are also very minimal. An area we see a lot changes in response to exercise is our cardiovascular system and muscular system. The ability to deliver oxygen (and other substances) depends on the proper functioning of the cardiovascular system (Plowman Smith, 2011, p.323). As we exercise the need for oxygen increases and carbon dioxide concentration in our blood increase. Chemoreceptor and baroreceptors detect this change in the blood. To get the proper resources to the proper place certain factors of our cardiovascular system start to increase during exercise. These factors include our stroke volume, heart rate, cardiac output, and systolic blood pressure. Stroke volume is the amount of blood that is ejected from the heart after every beat; the amount per minute is the cardiac output. Systolic blood pressure is the blood pressure during a contra ction (Plowman Smith, 2011). The kind of exercise will affect how much these factors will increase or how rapidly it will increase. For example, during the short term, light to moderate aerobic exercise make our factors increase rapidly. However, during incremental exercise, our factors will increase in a rectilinear fashion as the workload increases. Our vascular system also plays an important role as we exercise. When exercising we find that there is a decrease in resistance of the arteries and veins, in other words, we see an increase in vasodilatation. This allows for more blood to go to working muscle, while making sure the blood pressure does not rise excessively (Plowman Smith, 2011). Our cardiovascular system will also contribute to maintaining homoeostasis of our body temperatures. When it comes to thermoregulation the environment surrounding our bodies can be very influential. However, our body is able to maintain an internal temperature via metabolic heat production, body heat radiation, conduction, convection and evaporation. Our cardiovascular system plays a role by capturing the heat exerted by our muscular system and sending them to be released via our peripheral vascular system. One of our primary defences against heat stress, especially while exercising, is sweating. However, there are situations where the thermoregulatory and metabolic demands are not meet by the cardiovascular systems. In this case, an individual can develop heat illness such as heat exhaustion and heatstroke. That is why it is important for those who exercise to keep hydrated before, during and after exercise (Plowman Smith, 2011). Over time we will find that exercise will cause our cardiovascular system to adapt. With endurance training, we will see an increase in blood volume and plasma volume. However, the increase in plasma volume will be seen at the beginning of the training while blood volume increase will not happen until much later. As a result of endurance training, individuals develop a lower heart rate at rest as well as the maximal oxygen consumption (Plowman Smith, 2011). Approximately forty percent of the deaths in America are caused by cardiovascular disease. One of the top cardiovascular diseases is coronary heart disease. However, there are studies that show exercise can reduce the risk of coronary heart disease. Exercise can even reduce the risk of factors that cause cardiovascular diseases; such as properties of metabolic syndrome. Metabolic syndrome is characterised by high visceral abdominal obesity, dyslipidemia, reduced glucose tolerance, insulin resistance, and hypertension. Together, these are factors that can cause cardiovascular diseases. By exercising, we can reduce the risk of many diseases, not just one (Plowman Smith, 2011). The second system that is largely affected by exercise is our skeletal muscular system. Generally, our skeletal muscles are important for posture, heat generation, and motion. To help perform these actions our nervous system plays the control our skeletal muscles. A motor unit is the combinations of the motor neurone and the muscle fibres it stimulates. ATP plays an important role here. This is because one neurone gives the signal for the muscle fibres to contract; the muscle fibres will need the energy to contract and then relax (Plowman Smith, 2011). Human muscle fibres are categorised by contractile properties and metabolic properties. From the contractile perspective, we have fast-twitch fibres and slow-twitch fibres. The ability for the fibre to contract slowly or quickly has more to do with the motor neurone then the fibre. Alpha-1 motor neurones are larger, have high recruitment threshold, and faster conductivity velocity; innervate fast twitch fibres. Alpha 2 motor neurones are smaller, have slower conduction velocity and low recruitment threshold; innervate slow twitch fibres. Metabolically, fast twitch fibres can make energy via oxidation and glycolytic metabolism or just glycolytic metabolism. However, slow twitch fibres can only make energy via oxidative metabolism (Plowman Smith, 2011). Through studies, we have found that athletes that practice endurance activities will have a higher percentage of slow twitch fibres. Individuals who are involved in resistance activities will have a higher percentage of fast twitch fibres. However, it is believed that this is more genetically based, then based on nurture. That is to say, that it is easier for some who has a high amount of fast twitch fibres will be better at resistance activities. While those with high slow twitch fibres are better at endurance activities. Therefore, the contractile properties of muscle fibres cannot be changed via exercise; however, our metabolic properties can be. It is possible for training to cause enough fast twitch fibres to change metabolically, so that they switch from oxidative-glycolytic metabolism to glycolytic metabolism (Plowman Smith, 2011). While training and exercising, we must be aware of muscular fatigue and muscular soreness. Muscular fatigue results from a loss of muscle functions and is largely depend upon the type of muscle fibre being used. Different exercises will use different muscle fibres; therefore, different kinds of exercise will cause muscle fatigue differently. For example, in static activity hydrogen ions increase, glycolysis is inhibited, fewer calcium ions are released in the sarcoplasmic reticulum and there is an occlusion of blood flow. Any of these, if enough or a combination of all of them, can cause muscle fatigue. Muscle soreness is the same idea as overexertion (Plowman Smith, 2011, p. 547). There are two types: immediate-onset soreness and delayed-onset muscle soreness. Immediate-onset soreness is pain that occurs during and immediately after exercise. When over exercising hydrogen ion concentration and lactic acid levels increase, this increase causes an over stimulation of pain receptors. It is believed that this is what cause immediate-onset soreness. However, it is not sure what causes delayed-onset muscle soreness (DOMS). DOMS is the pain that is felt at least eight hours after exercising and, reaches peaks and falls over the next ninety-six hours. Athletes and trainers must beware to avoid these conditions because it can affect athletic participation and performance (Plowman Smith, 2011). Different exercises lead to muscle fatigue differently than another type of exercise. This is the same as the adaptations seen in our muscular system. Different kinds of exercises will lead to different adaptations. Resistance training is used to improve overall health, improve athletic performance; rehabilitate injuries, and change physical appearance (Plowman Smith, 2011, p. 580). Muscular adaptions, however, also rely heavily on their individual goals; and occur at different rates. Trainers must remember to apply a training program based on the individual or team and their capabilities (Plowman Smith, 2011). Metabolism, cardiovascular system, and the muscular system are the main aspects of our body that are affected by exercise. However, our other systems are also affected. Our skeletal system is important for protection, support, mineral storage, hematopoiesis and movement. Studies have shown that exercise has a positive effect on bone health and helps avoid disease such as osteoporosis. Physical activity creates an increase in mechanical force that leads to mechanotransduction. Mechanotransduction is the process of osteocytes modelling and remodelling the bones. This makes the bone stronger. Bending our bones also causes stress (compressive and tensile stress) that changes the hydrostatic pressure of our bones. The change in pressure increases the movement of the fluid within the bone. Fluid in the bone carries the nutrients and wastes; as well as results in the formation of new bone. Exercise helps the body to reach peak bone mass while still growing, offset menopause and slow down bo ne loss that occurs later in life. However, if exercise is done excessively their activity can exceed the adaptive ability of bone, resulting is overuse injury (Plowman Smith, 2011, p. 501). The nervous system was seen coming into play with our muscular system; however, our nervous system also works with our endocrine system when responding to exercise. When responding to stress in general, our nervous system and the endocrine systems will come into play. Since exercise is a stress, we see a response from the nervous system and the endocrine system. Specifically, the sympathetic and the parasympathetic come into play during different points of the exercise. The sympathetic nervous system (SNS), our fight or flight response, will come into play during exercise. While our parasympathetic nervous system (PNS), rest and digest, will be important for recovery; breaking down energy for our muscle recovery, taking deep slow breaths, and so on. The SNS will, during exercise, ensure to enhance our cardiovascular functions, regulate blood flow and maintain blood pressure and thermal balance, and increase fuel mobilisation (Plowman Smith, 2011. It has also been found that after lo ng bouts of exercise a group of neuropeptides called endogenous opioids is released in the central nervous system. Endogenous opioids, or opioids, are a famously know as opium from the best and for subsiding pain (Jonsdottir, 2002). While running as pain levels reach certain levels opioids are released, and are also known to cause runners second the wind or runners high (Widmaier, Raff Strang, 2008, p. 171). The endocrine system also plays a role when exercising. While exercising there is an increase in the release of our metabolic hormones; glucagon, insulin, growth hormone, epinephrine and norepinephrine. These hormones work together to maintain blood glucose levels and mobilise fuel for ATP production. Epinephrine and norepinephrine also help to enhance cardiac function and maintain fluid and electrolyte balance. Adaptive, our endocrine system may change due to exercise. However, it depends on the individual. The adaptation could make the individual more sensitive to lower levels of hormone so that the same effect occurs following training even without a changing baseline (Plowman Smith, 2011, p. 645). Our immune system will also respond to exercise. It has been found that will moderate exercise will lead to higher numbers and activity of neutrophils, natural killer cells, B and T cells, macrophages, and more. Thus making out immune system stronger. However, during excessive exercise, we see a decrease in natural killer cells, lymphocytes and neutrophils. It is believed that this is likely for the vulnerability to acute infections. No pain, no gain, is what is often said among friends when exercising. It is important to remember that exercise is a stressor, and that one will feel pain as a result. It is also important to beware of the effects of over-exercising. Exercise, if done right, can help avoid, delay and lessen the effects of disease; as well enhance our bodies to function to its prime.

The Mind of Kurt Vonnegut Essay -- Biography Biographies Essays

The Mind of Kurt Vonnegut Kurt Vonnegut is one of the preeminent writers of the later half of the twentieth century. His works are all windows into his mind, a literary psychoanalysis. He examines himself as a cog in the corporate machine in "Deer in the Works"; as a writer through the eyes of Kilgore Trout in several works; and most importantly, as a prisoner of war in Slaughterhouse-Five. Vonnegut created short stories and novels that dealt with events in his life. One of the most obvious self examinations is in "Deer in the Works". The short story is based on his experiences as a publicist at the General Electric Company Research Laboratory in Schenectady, New York. "Deer in the Works" takes place over two days in the life of David Potter as he begins his employment at the Ilium Works of the Federal Apparatus Corporation. He is assigned to cover a deer trapped in a remote corner of the Works. Potter gets lost in the Works himself and feels just as trapped as the deer. He eventually frees the deer and escapes the works to return to his newspaper. Vonnegut felt trapped like Potter does, and left General Electric in 1951 to write full time. Before World War II, Vonnegut was enrolled at Cornell University studying biochemistry. He was surrounded by scientists and machines and as a result, his first literary works were based on that influence. Vonnegutà ¸s early writings were not accepted as serious, mainstream literature due to their scientific nature. He was considered a science fiction writer by literary critics. That label caused him to be largely ignored. He created the character Kilgore Trout, a science fiction writer, to... ...hort-term events like that. Dresden was astonishing, but experiences can be astonishing without changing you" (Reed 776). Despite these claims to the contrary, the experiences at Dresden had always played a large part in his writings. His experiences have always shaped what Kurt Vonnegut has written. He said to his brother, Bernard, that he wrote for an audience of one, his dead sister; but he truly wrote for himself. He wrote about his experiences as a prisoner in Slaughterhouse-Five, as a publicist in a major corporation in "Deer in the Works", and as a writer through the character Kilgore Trout. Vonnegut examined his thoughts through the eyes of David Potter, Kilgore Trout, and Billy Pilgrim. His works are all deeply personal windows into the psyche of Kurt Vonnegut.

The Unique Corporate Culture in Google

The Unique Corporate Culture in Google Executive Summary The internet giant of search engine â€Å"Google†, always rated for the â€Å"Best Workplace†, â€Å"Best Employer† in the recent ten years. Why? Except the professional technology, Google’s great and unique corporate culture made so. The feature of Google’s corporate culture is equality, free and human oriented.The company provide the most luxury and comfortable work environment to its employee, encourage them relax more, play hard and work hard. From Google’s case, more and more companies realized the perks and benefits for the employee are no longer only medical, insurance, overtime pay, free coffee and two weeks holidays. In Google, nobody need to punch the clock, you can work in your own â€Å"time zone†.If you don’t want to leave your pet in the working time, bring it in your office, you can stay with it in every minute. You don’t need bring the lunch box to t he company, because it has free breakfast, lunch and dinner every day. Vast kinds of facilities are well-established. Like the professional massagist, the gym, the massage chair, the bicycle, the dry clean laundry, the slides, the electronic scooter, the oil change, and so on.Everything seems great, but if the employee has other demand, they can speak to the founder or CEO directly, maybe the request would be excessive or crazy, but if it is feasible, Google will satisfy employee in every possible way. The open policy reflects the equality in Google. Every employee can see the boss and co-workers work plan and schedule. Google think this way can let all employees get the information about company’s program progress and developing direction, make them feel they are trusted and will be one of the groups always.

Which is more effective in fighting crime, knowledge?

Sociologists, in an attempt to explain and point out the reasons behind delinquency, have concluded that there are connections between specific youth behaviors with the home environment, family background, the neighborhood, associations, and many other aspects that together, or separately affect the formative years of young people’s social environment. Delinquent children usually come from a background of difficult circumstances. Parental alcoholism, poverty, breakdown of family, abusive conditions in the home, death of parents during armed conflicts or drug overdose, and the HIV/AIDS scourge, and etc. are some of the various reasons that can leave children virtually orphaned.One or both parents may be physically present, but because of irresponsibility on their part (if even one of them is addicted to drugs or alcoholic), a child may grow developing certain ways and attitudes that are directly/indirectly caused by the parent/s addiction or drug-related behavior. In this case, true delinquency lies on the parents; and the children are, in a way, orphaned or unaccompanied, and without any means of subsistence which, in the first place, the parents’ fundamental responsibility to provide. Generally, and increasingly, these children are born and/or raised without a father.They are first in the line of those who are at greatest risk of falling into juvenile delinquency. Without noticing it as it is typical of any youth to be lacking in prudence, with newly embraced group, the gang, a corresponding subculture starts to assimilate them, and before long, they start to engage in activities of adult criminal groups. It is usually after being engaged in criminal activities for an extended period of time with its accompanying consequences (such as ending up in prison or rehabilitation institutions for drug addicts) that delinquents realize they are into a very dangerous zone.A large portion of all juvenile violations (between two-thirds and three-quarters) ar e perpetrated by youths who are members of certain gangs (Venkatesh, 1997). Unlike in school and their family, these have no strict rules to be followed except loyalty to the group. It gives young people esteem when they somehow feel they are the â€Å"rule† in themselves. This is the lure of gangs. It gives the promise of fulfillment to would be delinquents. Popularity, access to the powerful figures on the streets, freedom to express one’s self, as well as easy flow of money (if the gang is also involved in some illegal activities such as drug dealings, which is common in most gangs) are seemingly within grasp of anybody who just have the guts to dare (OJJDP, Mar. 2003).Children who are well taken care of by their parents and are thus adequately supervised are at less odds to be involved in criminal activities. Studies have proven that. A dysfunctional family, on the other hand, which is commonly characterized by regular conflicts, parental negligence, poor communica tion because of absorption to outside activities by parents, are always assumed to be the breeding ground for delinquents (Venkatesh, 1997).Studies on Risk versus Protective FactorsAn insightful paper prepared by Resnick describes the theoretical viewpoint that risk and protective factors are two things that may â€Å"mirror† each other. Risk factors like low academic performance increases the possibility of child or youth’s involvement in activities that may harm themselves and others while protective factors such as high academic performance increases the likelihood also of the individual committing aggression against another.These factors reside in an individual and that a disproportion of one especially the â€Å"risk factors† over the other indicates a caution or warning; the person may traverse in a direction which may foster a tendency to exhibit aggression or violent behavior. In the study, identifying these balance or imbalance within individuals may he lp reduce the occurrence of school violence by early detection of symptoms thus, interventions may be employed coming from various strategic points like the home, and the school and the community (Resnick, 2004).According to the Laub (1998), the home and the school are milieus that importantly direct the development of aggression or violence. Aggression at home significantly reflects what may eventually occur as aggression or violence in school, though not always. Male students attack peers or other male students. In addition, teachers are hurt either by verbal abuse, physical injury or threats of aggression. Fights that commonly occur in the campuses relate to â€Å"possession of toys, equipment and/or territory, about retaliation, & rules of games† (Laub, 1998).Nature of Violence or Aggressionâ€Å"From very early, the oxygen of the criminal's life is to seek excitement by doing the forbidden.†-S.SamenowA radical turn from the contemporary to classical rationalizatio ns on violent behavior equivalent to possessing a criminal mind, Stanton Samenow offered a quite â€Å"sweeping† point of view based on what he calls â€Å"errors of thinking.† Whereas years spent in studying and treating adolescence clinical disorders, he had leaned upon the understanding that adolescents, criminal behavior and/or violence in general have social determinants as a major factor, this change of mind was brought about by a collaborative work with another practitioner Dr. Yochelson (Genre,http://www.criminology.fsu.edu/crimtheory/samenow.htm).An elevated fear on the occurrence of violence in school is expectedly high not only because of what happened in Virginia Tech recently; this is because other forms of aggression or violent acts committed by students have not changed instead, increased in number among campuses today. In an excellent study by Jaana, the author specifically isolated these acts as becoming the source of fear for the average students to e xperience anytime during their school lives.The study reveals that suburban schools are also profiled as becoming unsafe these days. These violent activities can be in the form of physical attack for no apparent reason or provocation, fights without using any weapon, pilfering, breaking and entering school property, and vandalism. In addition, victimization occurs, in the manner of students stealing property of another (e.g., books etc.), being threatened because of racial or cultural difference, bullying, and threats of injury to teachers and not only to students among others (Jaana, 2001 in http://www.ncdjjdp.org/cpsv/Acrobatfiles/statistics_2008.pdf).Reference:Genre, C.T. 2007. â€Å"Stanton Samenow:The Criminalpersonality).

Othello/ Good vs Evil Essay

Life in general is often used as a system of ways to define what kind of person you are by its end. Shakespeare takes that theory into test upon his characters in his work of the famous play Othello. Through the verbal twists and turns along with the addition of color symbolisms, the personalities of Othello, Iago, Desdemona are revealed to their fullest extents, along with their own balance of good and evil within. When this is realized by this famous Shakespearian work, the judgment of good and evil is carried out, and as a result of mass purging of emotions, neither prevails in the resolution. Othello, due to his Moorish nature but at the same time morally white and untainted, can be considered grey with the opening of the play, but possesses the potential to become either the most brilliant white or the darkest black. From the way that he is described by Iago and sometimes Brabantio, he is a dark beast lurking in the shadows, but he is as white as he can be by the Duke. Grey is a color not quite white nor black, hesitation and confusion wavering behind his eyes. This confusion is caused by his naivete at trusting people too easily, and Iago eagerly takes this weakness to his advantage. So that when Iago manipulates Othello, Othello unknowingly gives in to the temptation, even going as far as telling Iago â€Å"I am bound to thee for ever† (III. iii. 242). Othello at this point is completely taken in with Iago’s mind poisoning and willingly submits to him, yielding to his trickeries. Inevitably with a little push from Iago, Othello slowly goes down the path of dark and pure blackness, with murder evident in mind. With Iago’s tampering of his inner moralities, Othello turns black like a speeding snowball, once Iago set him on the right path. Everything else Othello had done the damage himself; Iago only suggested the notion in the most subtle of ways. Thus he sometimes â€Å"breaks out to savage madness† as Iago put it, when being put under such pressure (IV. i. 65). He is so far gone that he even has epileptic fits hearing of Desdemona’s infidelity. Othello turned out to be evil when he became so mad that he extended his hands to Desdemona’s neck and smothered her to death with a pillow. Only after he kills her he realizes too late that Desdemona is innocent from the start, and has been shining ever since, and only the darkness has clouded his vision and perception of her tempting him to kill her. The fact that he has succumbed to that temptation shows how the good in him has lost its battle to the evil corruptions of Iago, even though he made some futile struggles against them. Othello has given in towards evil because of his weakness and his judgment is heightened by his murder of his wife Desdemona. Even though at the end he seems repentant towards the deeds that he has done, he still lost, and decides to end his sufferings by offering his final defeat — his life. Even so, evil has not truly prevailed by the end of the play, and is instead overcome by the good that is the Venetian society. Iago holds one true goal in his plotting — to corrupt Othello so that he will turn against the ones closest to him. But as the play progresses, there also seem to be a power struggle, whereas Iago is jealous of Othello’s position and empowering authority and wants Othello out of the way so that he can assume power. Iago is tired of acting like one â€Å"courteous and knee-crooking knave† like he always appears to be (I. i. 46). He does not the type of servant that is humble and waits for his master like an obedient mule, and only to be tossed out when he is all weathered and old. No, since Iago is unable to choose to be a master, he is the servant that feeds off the fame and â€Å"keep yet their hearts attending on themselves,† still showing his service to his master but instead is more self-preserving with no attachments at all towards the master (I. i. 52). Iago chooses to follow someone who is able to be manipulated, and declares upon the opening of the play that he is no loyal servant to Othello. He puts up a front of honesty and seeming whiteness, but inside he is just as black as he is white on the outside. In this way he goes to battle the good, the whiteness in Othello, and in turn making his defeat beneficial to his evil plans. It is very obvious that his challenge against good is a victory when Desdemona is murdered by Othello, but evil’s victory is short-lived. Almost immediately, Iago’s wife Emilia turns against him and uncovers the blackness that he truly is underneath his false honesty. Ulterior moves exposed, he is hunted down by the officials of Venice after killing Emilia and brought back to be tortured. His plans have failed, lost to the good and foiled by societies’ ironies, betrayed by his wife, after successfully making Othello kill Desdemona for doing the exact same thing. In this way, evil has not prevailed, and goal gone unaccomplished by good’s interruption. Evil may have won Othello and Desdemona’s soul, but in itself evil did not triumph over good, as Iago lost his power and discovered and punished accordingly. All in all, evil and good is expressed as a never-ending fight in Shakespeare’s tragedies. None overcomes the other, ending the play in a stalemate and effectively purges deep emotions within the audience. Also, the inevitable stalemate that leaves both sides wounded stirs some incomprehensible feelings as to why humans even bother fighting at all in the first place. It is not humans’ place to judge, but to act accordingly to the great director that is the world. World puts humans through excruciating hardships in order to define a person’s soul’s worth at the time of death. Life is the judgment for humans, as they, like Othello, contain both black and white and has the potential to turn either way down each individual life’s paths. Evil and Good is recognized as each quality manifests during a person’s lifetime, and only at the moment of death is he able to look back and see what he truly is without hindrance of the other.

“Bartleby the Scrivener” by Herman Melville

This short story entitled â€Å"Bartleby the Scrivener† by Herman Melville gave as an idea about the several interesting characters with many poles apart personalities. But the one that was caught our attention was Bartleby. This man was a scrivener, which, in simple words, was a human description of a modern day copy machine. He did his job exceptionally well; he never stopped working, and got things done rapidly and proficiently. But, Bartleby was a man of one phrase: â€Å"I would not prefer to†. He said this as a reply to everything that was requested of him other than to copy documents.Well in fact, he absolutely refused what his boss asked him to do. This confused the reader about Bartleby. But, Melville, never seemed to present an answer to this mystery. Another thing that caught my attention was that he never said â€Å"I will not. †, but â€Å"I prefer not. † This implied us that the individual he was talking to has a choice as to what Bartleby wo uld or wouldn’t do, but in such a way, it was explained that he puzzled the narrator’s feelings, and for a long period of time, it caused him to accept the statement as a â€Å"no†.I concluded this as one of the weaknesses of the narrator as a business owner, but at the same time made me thought what was Bartleby’s reason for responding in such a way. I also found out very interesting about him was his living habits. He decided to stay at the office which he didn’t even bother to ask the permission of his boss (the narrator). He washed, slept, and worked in that place also. He refused (or stated that he would â€Å"prefer not†) to adjust his living arrangements.The narrator transferred his business because Bartleby didn’t want to vacate the place after the new occupant arrived. The narrator understood him but in the end Bartleby was put into prison because of him also. To cut the story short, Bartleby died at the prison. The narrator had an investigation and discovered that his last job caused him some mental affliction and psychological disturbance. In my own point of view, I think if the narrator learned about the real situation of Bartleby as early as possible, he would treat him with compassion and understanding.The reason of Bartleby by telling â€Å"I prefer not to,† â€Å"I prefer not to,† was to isolate his self among the rest and his lack of interest for involvement. The narrator explained in the passage below how he treated Bartleby, â€Å"I placed his desk close up to a small side window in that part of the room, a window which originally had afforded a lateral view of certain grimy backyards, and bricks, but which, owning to in subsequent erections, commanded at present, no view at all, though it gave some light.Within three feet of the panes was a wall, and the light came down from far above between two lofty buildings, as from a very small opening in a dome. Still further to satisfac tory arrangement, I procured a green folding screen, which might entirely isolate Bartleby from my sight, though, not remove him from my voice. † The narrator, himself, had separated and secluded Bartleby from the real world. In my opinion, what the narrator did wasn’t able to help Bartleby overcome his trauma from his last work.It only added to the emotional problems that he hid from the start. He used to tell the word â€Å"I prefer not to† because he thought that he couldn’t do anything aside from his work and he didn’t even bother to mingle with other people because he considered himself unacceptable to whatever or whoever. For me, Bartleby didn’t want to isolate himself from other, in such a way that they couldn’t understand him, but the truth was the people that surrounded him, did the isolation.Because of that, he developed negative impressions toward himself and others. As I analyzed this short story, I came up with the judgmen t that isolation was risky. It can drive an individual to insanity, make him speechless, or even kill his own self. The lesson was not to allow your own self to be overcomed by prejudices and discrimination, and let yourself be isolated. â€Å"Bartleby the Scrivener† by Herman Melville This short story entitled â€Å"Bartleby the Scrivener† by Herman Melville gave as an idea about the several interesting characters with many poles apart personalities.
