Psychological Effects one can have due to Sleep Deprivation Essay Example for Free

Psychological Effects one can have due to Sleep Deprivation Essay According to Kozier et Al. (2002), sleep is the state of being conscious wherein there is a decrease of perception, and reaction to the environment of an individual (p. 953). Sleep exerts physiologic effects on both the nervous systems and other body structures and also it restores normal levels of activity and balance among parts of the nervous systems (p. 956). There are two types of sleep, NREM sleep and REM sleep, NREM sleep or non-REM sleep is a deep, restful sleep and some physiologic functions were decreased. It is also referred to as a low wave sleep because when a person sleeps the brain waves tends to slow than the alpha and beta waves of an awake person. NREM sleep is divided into four stages: stage 1- very light sleep wherein the person feels drowsy and relaxed, stage 2- light sleep that will last only from ten to fifteen minutes, stage 3- domination of parasympathetic nervous systems that slows down the heart and respiratory rates as well as other body processes and sometimes snoring may occur and the fourth stage will be the deep sleep is thought to restore the body physically, dreams and rolling of the eyes may occur in this stage. Another type of sleep is the REM sleep or the rapid eye movement sleep that constitutes 25% of sleep of a young adult and usually recurs every ninety minutes and lasts five to thirty minutes. On the other hand, dreams in REM sleep were usually remembered because it is consolidated in the memory (pp. 953-954). There are many factors that may affect sleep of an individual, quality of sleep and quantity of sleep were both affected by a number of factors. The quality of sleep is the ability of an individual to stay asleep and to get the required amount of REM and NREM sleep while the quantity of sleep is the total time the individual sleeps. Age, environment fatigue, life style, psychological stresses are just some of the factors that indeed affects the sleep of an individual (p. 956). Literature Review In an internet article, they listed six persons that have a contribution in sleep research. A French Scientist Henri Pieron authored a book entitled â€Å"Le probleme physiologique du sommeil,† which was the first text to examine sleep from a physiological perspective. This work is usually regarded as the beginning of the modern approach to sleep research. Dr. Nathaniel Kleitman, now known as the â€Å"Father of American sleep research,† he started working in Chicago in the 1920’s questioning the regulation of sleep and wakefulness and of circadian rhythms. Kleitman’s crucial work included studies of sleep characteristics in different populations and the effect of sleep deprivation. Another contributor is questioning the regulation of sleep and wakefulness and of circadian rhythms. Kleitman’s crucial work included studies of sleep characteristics in different populations and the effect of sleep deprivation. Dr. William C. Dement extended Dr. Kleitman’s path of research. Dement described the â€Å"cyclical† nature of nocturnal sleep in 1955, and in 1957 and ’58 established the relationship between REM sleep and dreaming. In 1958, he published a paper explaining that in a sleeping cat there is a cyclic organization existence, thus creating an explosion of fundamental research that gathers researchers from different fields of specialty. For the next 20 years, Michel Jouvet leads to an identification of REM sleep as an independent state of alertness, which he called â€Å"paradoxical sleep. Another one is H. Gastaut and his colleagues discovered the presence of apnea during sleep in a subgroup of â€Å"Pickwickian† patients (1965) that lead them to an outbreak of investigations of the control exercised by the â€Å"sleeping brain† on the body’s vital functions. His work eventually led to the new discipline of â€Å"sleep medicine† (A brief history of sleep research, â€Å"n. a. †). Sleep deprivation and its causes According to Kozier et Al. (2002), sleep deprivation is only one out of many common sleep disorders. They defined sleep deprivation as a syndrome of prolonged disturbance that leads the amount, quality, and consistency of sleep to decrease and thus produces a variety of physiologic and behavioral symptoms, its harshness will depend on the degree of the deprivation. Again there are two types of sleep deprivation REM and NREM deprivation, the combination of the two deprivation increases the severity of symptoms. Alcohol, barbiturates, shift work, jet lag, extended ICU hospitalization, morphine, and meperidine hydrochloride are the causes of REM deprivation, while all of the causes of REM deprivation plus diazepam flurazepam hydrochloride, hypothyroidism, depression, respiratory distress disorders, sleep apnea, and age causes NREM deprivation, and both REM and NREM deprivation is caused from the combination of both REM and NREM deprivation causes (p. 959). Another cause of sleep deprivation is from the psychological stress wherein anxiety and depression frequently disturb sleep. A person can’t relax adequately to get to sleep if he or she is having a personal problem. Another factor is alcohol and stimulants, people who drinks alcohol excessively has the higher rates of sleep disturbances. Alcohol disrupts REM sleep even though it fastens the onset of sleep. Diet- weight loss is accompanied with reduced total sleep time as well as broken sleep and earlier awakening. Smoking, cigarettes contains nicotine that has stimulating effects on the body and may cause in difficulty of falling asleep. Motivation, person’s desire to stay awake can cause a fatigue, and illness, an ill person is more prone to sleep deprivation, in their condition they need to have more sleep, but a patient in a hospital is disturb by their time to take their medicines, and respiratory conditions can also disturb sleep thus disturbing their total time of sleep a person is required to have (p. 956). Psychological and physical effects of sleep deprivation  The effects of sleep deprivation to the body is like a chain reaction, its main target is the brain, since the brain is the control unit of the body, the brain controls and is responsible for the homeostasis of the body, once the brain is affected many imbalances may occur. For REM deprivation excitability, restlessness, irritability, increased sensitivity to pain, confusion and suspiciousness, and emotional liability can possibly be the effects. For NREM deprivation one may show hyporesponsiveness, withdrawal, apathy, feeling physically uncomfortable, lack of facial expression, and speech deterioration. For both REM and NREM deprivation, inattentiveness, decreased reasoning ability and the ability to concentrate, marked fatigue manifested by blurred vision, itchy eyes, nausea, headache, difficulty in performing activities of daily living, lack of memory, mental confusion, visual or auditory hallucinations and illusions can be its primary effects to one’s both psychological and physical aspect of a person. Since stress is one of the major factor affecting sleep deprivation whether it’s psychological or physical stress. As you think more and focuses your mind into the problem, your mind will become more fatigue (p. 959). Based on the book by Biron et Al. (2006), stress may lead to some psychological problems and may interfere with effective intrapersonal and the intrapersonal behavior of the individual. A person experiencing prolonged stressful events may suffer from feelings of helplessness and hopelessness, and consequently, undermining his self esteem. Impaired task performance is another effect of stressful mind; it interferes with our ability to successfully perform a task and responsibilities expected. And disruption of cognitive functioning, people who are under stress are likely to experience loss of concentration, disorientation, and forgetfulness (pp. 184-185). Treatment for sleep deprived persons According to the book made by Kushida (2005), pregnant women are also prone to sleep deprivation. In treating sleep deprivation for pregnant women, they recommended seven treatments to minimize maternal and fetal health risk: a) women should try to seep on the left side and avoid sleeping in supine position.  Avoiding it will ease the stress of the heart, will reduce constriction of the space available to the fetus, will reduce pressure to the inferior vena cava that carries blood back to the heart from the feet and legs, b) if symptoms of RLS are present, consider an evaluation of ferritin, hemoglobin, and folate levels and supplement when indicated, c) treat sleeping- disordered breathing with CPAP, d) avoid staying in bed when unable to seep, e) address anxiety provoking issues to reduce overall level of arousal, f) Consider regular exercise, pregnant women who exercise three times a week for at least thirty minutes have less insomnia and anxiety than pregnant women who do not exercise, and g) treat psychophysiological insomnia with empirically supported cognitive behavioral therapy for insomnia (p. 185). Another form of treatment is discussed by Greist and Jefferson (1992), psychosurgery is a rare treatment; it is not then advisable if other treatments have not been tested to a patient. Careful neurosurgical interruption of brain pathways has been shown that fifty percent of patients has been helped to this kind of treatment (pp. 79-80). Conclusion: Sleep is really a helpful in obtaining our health; it restores our body’s energy. Sleep deprivation is not really a syndrome but an effect due to some disturbances, stress, and anxiety that makes our brain to send signal to our body to be awake, an unnecessary awakening that affects our total time of sleep.  When our body is stressful or lack of average sleep needed by each individual, our brain do not work properly thus affecting our lifestyle, our ability to think and cope up with problems, and then other diseases may occur if not immediately taken to concern, because stress attacks our brain and knowing that our brain is the control center of our body. Recommendation: If sleeplessness and the listed signs and symptoms occur, it will be a clever decision if you consult a Doctor immediately prior to health concern. It is also a best way if symposiums will be conducted or seminars that discuss about Sleep deprivation to school and or universities so that students and educators will be aware to the effects of sleep deprivation that one can possibly have due to body exhaustion and abuse.

The Entertainment Value of a Buffy the Vampire Episode :: Buffy Vampire Slayer Essays

In this essay I ultimately want to address the musical episode of Buffy the Vampire Slayer, "Once More with Feeling" (season 6, episode 7). However, I do not want to look at this episode in isolation from the remainder of the Buffy franchise but rather argue that it exemplifies a certain entertainment strategy that courses through the Buffyverse. Now it seems to me that entertainment is either too often denigrated as a specific ideological formation that produces negative effects of audience passivity as against more overtly challenging texts, or, alternatively, entertainment is celebrated within a postmodern theoretical framework that views the multiplicity of pleasures afforded as inherently productive and even oppositional. Alternatively I want to concentrate on entertainment for entertainment's sake which is to say as a dialectical operation that in Fredric Jameson's terms intermingles wish fulfilment and repression by arousing radical fantasies in order to contain them (Jameson, 1990: 25). In order to analyse this mechanism I will concentrate less on consumers and ideology (that assumes unilateral transmission) and more on fans and affect (that inscribes a dialectical procedure into reception). What seems to me to be of specific interest therefore is the manner in which Joss Whedon, Marti Noxon and the other writers/directors working on Buffy for Twentieth Century Fox target affect and fans by constructing scenarios that feed into and exceed audience expectation. I will argue that his formula culminates in the episode "Once More With Feeling" that ventures beyond Jameson's dialectical formula in that it appears to wilfully play with wish fulfilment/invocation that both figuratively and literally run the risk of arousing utopian fantasies that cannot be contained. Before turning to the musical episode in particular I believe our exposition would benefit from a brief survey of critical approaches to the Buffyverse. The critical material on Buffy the Vampire Slayer, in print at least (see here the Slayage online journal), is expanding but currently somewhat limited. However, as a general rule two tendencies emerge. The first is to treat some self-contained aspect of "Buffy the Vampire Slayer" as an ideological work. Such analyses concentrate upon the encoded more or less implicitly pre-determined messages that the text transmits. Certainly some ideological responses are definitely triggered by Buffy and I will briefly make reference to two critical examples. Brian Wall and Michael Zyrd adopt a Marxist master frame of analysis to determine the world historical content of Buffy.

Mo Yan’s the Garlic Ballads: Saga of Suffering and Solitude Essay

They are, instead, people with their own shortcomings and prejudices, and by understanding that, Mo Yan shows the true power of an artist–rather than stoop for the easy message, he dives into the actuality of his characters to make them empathic and flawed, and allow us to root for them and cringe when we realize that they simply don’t have the wisdom to always act correctly. When it comes to the plight of the farmer and the destitute, Mo Yan has experience in spades. The Garlic Ballads tells the tale of a group of Chinese peasants whose lives are dependent upon selling their garlic crop; when harvests exceed governmental estimates, officials curb the amount of garlic that can be brought to market, setting off a violent chain of events. Against this backdrop, Mo weaves presents three stories: that of two lovers, which dominates the novel, as well as a familial conflict and the relationship between two friends. Howard Goldblatt’s translation is so good as to make the reader mistake this for an English novel; the prose is nearly flawless. Set in rural China, The Garlic Ballads explores the misfortune of ordinary Chinese farmers during the post revolutionary period. The very title which focuses on the word ‘Ballads’ reveals that it is a love story in particular spiced by magic realism. The harrowing experiences make the stuff of the novel. The small dramas of the Gao and Yang families, set against a slightly larger but nonetheless miniscule backdrop of rural corruption gets steadily deeper as it progresses, illuminating the paradoxes of modern China and the unchanging demands of love, family, and duty. There are also other heterogeneous elements – an arranged marriage, a botched directive from central agricultural planners, a drunk driver with government connections. All are woven into a coherent whole through the poetic vision of Mo Yan who easily peddles in realism. This novel which focuses on the aftermath of an uprising a tragic story which depicts both a very specific time and place and sheds light onto basic human truths. The people of Paradise County have been encouraged, if not ordered, to grow garlic, and so garlic has infused itself into every aspect of the people’s lives–their breath reeks of it, their celebrations tainted with it. But the governing officials of Paradise County are out to grab up every copper they can, and so out come the taxes for traveling the roads to the co-op warehouses, the penalties, the closures, and one day the garlic farmers have had enough and act out against the officials making their lives so full of hardship. The government retaliates, and Mo focuses on some of the victims. First, there is Gao Yang, who suffers enough with a blind daughter and a new son soon to be born, but he is beaten and brought to jail. One who escapes at first is Gao Ma, a former soldier who longs to marry Jinjun, whose family have agreed to marry her to someone else, but Gao Ma and Jinjun do not take the alternate marriage lightly, and trouble ensues from there. Jinjun’s mother, Fourth Aunt of the Fang family, is also sought after in the police hunt since she won’t stay quiet about her husband being run over by a government official, and the lives of these peasants intertwine through the courses of love and justice. The Fang family is cruel to both Jinjun and Gao Ma as they try to reject the lovers’ vow to be married, and Gao Yang suffers humiliation and torment from his cellmates. Fourthly we have the character of the Aunt who appears to be tyrannical at home, but in jail she becomes a different creature altogether. At times, she is bawdy and scatological, at other times heart-breaking and lyrical. Thus through the characters, Mo Yan gives us the entirety of the human spectrum in his novel. The main story in The Garlic Ballads details the tragic love story of Gao Ma and Fang Jinju. This story is told in parallel with the life of Gao Yang and some other stories. All are inter-related. The background is a Chinese village in the mid 1980s. The details make it frightfully real. The central focus in the book is however on an invasion and trashing by an angry mob of the local governmental offices. We do not see this event occur until the end of the book, yet it colors every moment in the lives of the Fang and Gao families of Paradise County. It is understandable that the Beijing government would suppress a novel that shows most of its local officials to be bloated satraps and its policement to be little better than thugs, applying cattle prods to their prisoners and beating them mercilessly. Equally villainous, however, are the Fang family, who force their daughter to marry an old man in a three-in-one arranged marriage that guarantees that their crippled eldest son also gets a bride. In a grisly scene, the marriage deal finally goes through after both the daughter and her fiance commit suicide: Their bodies are dug up, their remains are mixed together, and they are re-interred in a single coffin. The full picture of alternating hopelessness and rebellion emerges slowly and tragically, and the disparate elements weave together into an elegant and moving whole. The Swedish Academy which selects Mo as the recipient of the Nobel Prize praised his ‘hallucinatory realism’ saying that along with his other writings, Sorghum, The Big Breasts and Wide Hips, The Garlic Ballads ‘merges folk tales, history and the contemporary’. Mo in his writings mingled fantasy and reality, historical and social perspectives and thus created a world reminiscent in its complexity of those in the writings of William Faulkner and Gabriel Garcia Marquez. Although Mo is the writer of eleven novels and a hundred of short stories, The Garlic Ballads seems to be his masterpiece. Born in 1955 to parents who were farmers, Mo Yan – a pseudonym for Guan Moye; the pen name means â€Å"don’t speak† – grew up in Gaomi in Shandong province in north-eastern China. The cultural revolution forced him to leave school at 12, and he went to work in the fields, completing his education in the army. He writes about the peasantry, about life in the countryside, about people struggling to survive, struggling for their dignity, sometimes winning but most of the time losing . Arundhati Roy’s A God of small Things is graphic and captivating, but seen from that perspective, The Garlic Ballads is ten imes more so. The novel depicts simple people living in hard times, in very helpless circumstances. Basically there was no way out, and people could only console themselves that their lives were `fated’. â€Å"I think writers write for their consciences, they write for their own true audiences, for their souls,† Mo said in an interview with  China Daily. â€Å"No person writes to win awards. † Today the best reward in literature comes to him. In fact he is the first Chinese writer to win this reward in Literature. The Garlic Ballads seems to have gained prominence no less than Marquez’s 100 years of Solitude.

The Value of Fiction - The uses of fiction in bringing history to life

We history buffs are a rare breed. Happy are the hours we spend poring through pages of dusty old books, wandering through museums full of armor and tapestries, and deciphering forgotten languages in primary sources. Those who have never been bitten by the history bug find it hard to understand what attracts us -- until they are bitten themselves. There are many different ways history lovers have been drawn into the fascinating world of the past, but perhaps the most common is through a good story. The moment we begin viewing history as stories about real human beings with human motivations instead of mere dates, places and statistics, history can take on a whole new luster. Period literature can help bring the past alive with an epic tale, and so can modern historical fiction. If you are a history buff hoping to get a friend to share your passion for the past, or if you are new to history as a hobby and are trying to understand what others see in it, the best introduction may very well be a historical novel or film. Entertainment has ways of opening the mind to ideas that even the friendliest or most erudite of straight historical texts can never hope to achieve. It helps, of course, when the book is well-written or the film well-directed, and unfortunately historical fiction, just like any other genre, has many more mediocre examples than it does splendid ones. Yet once you find a truly excellent piece of historical fiction, the results can be highly rewarding. However, the trouble with getting your history from fiction is that its, well, fiction. This may seem excruciatingly obvious, but its surprising how many intelligent, educated, well-read individuals take what they read in a historical novel or see in a period film as fact. The Trouble with Fiction When done really well, fiction leaves its audience thinking they know what the medieval world was really like. If the work is accurate, thats wonderful; but alas, novels and films have been known to present a skewed version of events and to perpetuate common misconceptions about the Middle Ages. Of course, most readers realize that much of the dialogue and the private moments of real historical figures that are captured in text or on film are only speculation. They may be aware on some level that events are open to interpretation, and that what they read or see is just one of many versions of what might have happened. Yet even readers who are acutely aware of these facets of historical fiction often ignore any question of accuracy concerning general historical background, settings and costumes, and the details of daily life, accepting as given that this much, at any rate, is authentic. This may be the most dangerous pitfall of using fiction as a doorway to the past. In order to enjoy the experience of fiction, we can (and should) suspend disbelief, and suspend as well any analysis of its veracity as history -- while reading the story or watching the film. But once you close the book or leave the theater, its time to think again. Even the most carefully-researched historical novel can contain errors of fact, and the sad truth is that many such novels arent carefully researched to begin with. Unlike a historian writing a scholarly treatise, novelists dont have to support every assertion with documentary, archaeological or even secondary evidence in order to get their work published;* they just have to write a good story. And films are so notorious for lacking accuracy that some moviegoers take particular delight in counting the mistakes. Furthermore, scholarly views of the medieval world are constantly evolving; what was considered a fairly accurate picture of the Middle Ages in, for example, the 1970s may be rendered much less authentic by the research and new evidence uncovered in the last few decades. You will sometimes find authors standing on the shoulders of earlier writers and passing along the erroneous or outdated details of their predecessors, with very few readers ever the wiser. Evaluating Fiction Fortunately, historical fiction doesnt always misrepresent the past. There is excellent fiction available, works that bring the Middle Ages to life in a wealth of accurate detail (and tell a good story, too). And more and more, modern historical novelists are making serious efforts to provide an accurate version of medieval times. But how do you know how much of whats presented in fiction is true to life? Do you take the word of the blurb on the back cover? Can film reviewers really tell you when a picture of the past is realistic? Theres only one way to know for sure: find out for yourself. Pick up a factual history book, visit some websites, go to a museum, join a discussion list, and start your journey into the fascinating world of historical discovery. If fiction is the trigger that launches you into the past, its value cannot be denied.
