The Nobel Prize in Literature Essay Example for Free

The Nobel Prize in Literature Essay Once upon a time there was an old woman. Blind but wise. Or was it an old man? A guru, perhaps. Or a griot soothing restless children. I have heard this story, or one exactly like it, in the lore of several cultures. Once upon a time there was an old woman. Blind. Wise. In the version I know the woman is the daughter of slaves, black, American, and lives alone in a small house outside of town. Her reputation for wisdom is without peer and without question. Among her people she is both the law and its transgression. The honor she is paid and the awe in which she is held reach beyond her neighborhood to places far away; to the city where the intelligence of rural prophets is the source of much amusement. One day the woman is visited by some young people who seem to be bent on disproving her clairvoyance and showing her up for the fraud they believe she is. Their plan is simple: they enter her house and ask the one question the answer to which rides solely on her difference from them, a difference they regard as a profound disability: her blindness. They stand before her, and one of them says, Old woman, I hold in my hand a bird. Tell me whether it is living or dead. She does not answer, and the question is repeated. Is the bird I am holding living or dead? Still she doesnt answer. She is blind and cannot see her visitors, let alone what is in their hands. She does not know their color, gender or homeland. She only knows their motive. The old womans silence is so long, the young people have trouble holding their laughter. Finally she speaks and her voice is soft but stern. I dont know, she says. I dont know whether the bird you are holding is dead or alive, but what I do know is that it is in your hands. It is in your hands. Her answer can be taken to mean: if it is dead, you have either found it that way or you have killed it. If it is alive, you can still kill it. Whether it is to stay alive, it is your decision. Whatever the case, it is your responsibility. For parading their power and her helplessness, the young visitors are reprimanded, told they are responsible not only for the act of mockery but also for the small bundle of life sacrificed to achieve its aims. The blind woman shifts attention away from assertions of power to the instrument through which that power is exercised. Speculation on what (other than its own frail body) that bird-in-the-hand might signify has always been attractive to me, but especially so now thinking, as I have been, about the work I do that has brought me to this company. So I choose to read the bird as language and the woman as a practiced writer. She is worried about how the language she dreams in, given to her at birth, is handled, put into service, even withheld from her for certain nefarious purposes. Being a writer she thinks of language partly as a system, partly as a living thing over which one has control, but mostly as agency as an act with consequences. So the question the children put to her: Is it living or dead? is not unreal because she thinks of language as susceptible to death, erasure; certainly imperiled and salvageable only by an effort of the will. She believes that if the bird in the hands of her visitors is dead the custodians are responsible for the corpse. For her a dead language is not only one no long er spoken or written, it is unyielding language content to admire its own paralysis. Like statist language, censored and censoring. Ruthless in its policing duties, it has no desire or purpose other than maintaining the free range of its own narcotic narcissism, its own exclusivity and dominance. However moribund, it is not without effect for it actively thwarts the intellect, stalls conscience, suppresses human potential. Unreceptive to interrogation, it cannot form or tolerate new ideas, shape other thoughts, tell another story, fill baffling silences. Official language smitheryed to sanction ignorance and preserve privilege is a suit of armor polished to shocking glitter, a husk from which the knight departed long ago. Yet there it is: dumb, predatory, sentimental. Exciting reverence in schoolchildren, providing shelter for despots, summoning false memories of stability, harmony among the public. She is convinced that when language dies, out of carelessness, disuse, indifference and absence of esteem, or killed by fiat, not only she herself, but all users and makers are accountable for its demise. In her country children have bitten their tongues off and use bullets instead to iterate the voice of speechlessness, of disabled and disabling language, of language adults have abandoned altogether as a device for grappling with meaning, providing guidance, or expressing love. But she knows tongue-suicide is not only the choice of children. It is common among the infantile heads of state and power merchants whose evacuated language leaves them with no access to what is left of their human instincts for they speak only to those who obey, or in order to force obedience. The systematic looting of language can be recognized by the tendency of its users to forgo its nuanced, complex, mid-wifery properties for menace and subjugation. Oppressive language does more than represent violence; it is violence; does more than represent the limits of knowledge; it limits knowledge. Whether it is obscuring state language or the faux-language of mindless media; whether it is the proud but calcified language of the academy or the commodity driven language of science; whether it is the malign language of law-without-ethics, or language designed for the estrangement of minorities, hiding its racist plunder in its literary cheek it must be rejected, altered and exposed. It is the language that drinks blood, laps vulnerabilities, tucks its fascist boots under crinolines of respectability and patriotism as it moves relentlessly toward the bottom line and the bottomed-out mind. Sexist language, racist language, theistic language all are typical of the policing language s of mastery, and cannot, do not permit new knowledge or encourage the mutual exchange of ideas. The old woman is keenly aware that no intellectual mercenary, nor insatiable dictator, no paid-for politician or demagogue; no counterfeit journalist would be persuaded by her thoughts. There is and will be rousing language to keep citizens armed and arming; slaughtered and slaughtering in the malls, courthouses, post offices, playgrounds, bedrooms and boulevards; stirring, memorializing language to mask the pity and waste of needless death. There will be more diplomatic language to countenance rape, torture, assassination. There is and will be more seductive, mutant language designed to throttle women, to pack their throats like patà ©-producing geese with their own unsayable, transgressive words; there will be more of the language of surveillance disguised as research; of politics and history calculated to render the suffering of millions mute; language glamorized to thrill the dissatisfied and bereft into assaulting their neighbors; arrogant pseudo-empirical language crafted to l ock creative people into cages of inferiority and hopelessness. Underneath the eloquence, the glamor, the scholarly associations, however stirring or seductive, the heart of such language is languishing, or perhaps not beating at all if the bird is already dead. She has thought about what could have been the intellectual history of any discipline if it had not insisted upon, or been forced into, the waste of time and life that rationalizations for and representations of dominance required lethal discourses of exclusion blocking access to cognition for both the excluder and the excluded. The conventional wisdom of the Tower of Babel story is that the collapse was a misfortune. That it was the distraction, or the weight of many languages that precipitated the towers failed architecture. That one monolithic language would have expedited the building and heaven would have been reached. Whose heaven, she wonders? And what kind? Perhaps the achievement of Paradise was premature, a little hasty if no one could take the time to understand other languages, other views, other narratives period. Had they, the heaven they imagined might have been found at their feet. Complicated, demanding, yes, but a view of heaven as life; not heaven as post-life. She would not want to leave her young visitors with the impression that language should be forced to stay alive merely to be. The vitality of language lies in its ability to limn the actual, imagined and possible lives of its speakers, readers, writers. Although its poise is sometimes in displacing experience it is not a substitute for it. It arcs toward the place where meaning may lie. When a President of the United States thought about the graveyard his country had become, and said, The world will little note nor long remember what we say here. But it will never forget what they did here, his simple words are exhilarating in their life-sustaining properties because they refused to encapsulate the reality of 600, 000 dead men in a cataclysmic race war. Refusing to monumentalize, disdaining the final word, the precise summing up, acknowledging their poor power to add or detract, his words signal deference to the uncapturability of the life it mourns. It is the deference that moves he r, that recognition that language can never live up to life once and for all. Nor should it. Language can never pin down slavery, genocide, war. Nor should it yearn for the arrogance to be able to do so. Its force, its felicity is in its reach toward the ineffable. Be it grand or slender, burrowing, blasting, or refusing to sanctify; whether it laughs out loud or is a cry without an alphabet, the choice word, the chosen silence, unmolested language surges toward knowledge, not its destruction. But who does not know of literature banned because it is interrogative; discredited because it is critical; erased because alternate? And how many are outraged by the thought of a self-ravaged tongue? Word-work is sublime, she thinks, because it is generative; it makes meaning that secures our difference, our human difference the way in which we are like no other life. We die. That may be the meaning of life. But we do language. That may be the measure of our lives. Once upon a time, visitors ask an old woman a question. Who are they, these children? What did they make of that encounter? What did they hear in those final words: The bird is in your hands? A sentence that gestures towards possibility or one that drops a latch? Perhaps what the children heard was Its not my problem. I am old, female, black, blind. What wisdom I have now is in knowing I cannot help you. The future of language is yours. They stand there. Suppose nothing was in their hands? Suppose the visit was only a ruse, a trick to get to be spoken to, taken seriously as they have not been before? A chance to interrupt, to violate the adult world, its miasma of discourse about them, for them, but never to them? Urgent questions are at stake, including the one they have asked: Is the bird we hold living or dead? Perhaps the question meant: Could someone tell us what is life? What is death? No trick at all; no silliness. A straightforward question worthy of the attention of a wise one. An old one. And if the old and wise who have lived life and faced death cannot describe either, who can? But she does not; she keeps her secret; her good opinion of herself; her gnomic pronouncements; her art without commitment. She keeps her distance, enforces it and retreats into the singularity of isolation, in sophisticated, privileged space. Nothing, no word follows her declaration of transfer. That silence is deep, deeper than the meaning available in the words she has spoken. It shivers, this silence, and the children, annoyed, fill it with language invented on the spot. Is there no speech, they ask her, no words you can give us that helps us break through your dossier of failures? Through the education you have just given us that is no education at all because we are paying close attention to what you have done as well as to what you have said? To the barrier you have erected between generosity and wisdom? We have no bird in our hands, living or dead. We have only you and our important question. Is the nothing in our hands something you could not bear to contemplate, to even guess? Dont you remember being young when language was magic without meaning? When what you could say, could not mean? When the invisible was what imagination strove to see? When questions and demands for answers burned so brightly you trembled with fury at not knowing? Do we have to begin consciousness with a battle heroines and heroes like you have already fought and lost leaving us with nothing in our hands except what you have imagined is there? Your answer is artful, but its artfulness embarrasses us and ought to embarrass you. Your answer is indecent in its self-congratulation. A made-for-television script that makes no sense if there is nothing in our hands. Why didnt you reach out, touch us with your soft fingers, delay the sound bite, the lesson, until you knew who we were? Did you so despise our trick, our modus operandi you could not see that we were baffled about how to get your attention? We are young. Unripe. We have heard all our short lives that we have to be responsible. What could that possibly mean in the catastrophe this world has become; where, as a poet said, nothing needs to be exposed since it is already barefaced. Our inheritance is an affront. You want us to have your old, blank eyes and see only cruelty and mediocrity. Do you think we are stupid enough to perjure ourselves again and again with the fiction of nationhood? How dare you talk to us of duty when we stand waist deep in the toxin of your past? You trivialize us and trivialize the bird that is not in our hands. Is there no context for our lives? No song, no literature, no poem full of vitamins, no history connected to experience that you can pass along to help us start strong? You are an adult. The old one, the wise one. Stop thinking about saving your face. Think of our lives and tell us your particularized world. Make up a story. Narrative is radical, creating us at the very moment it is being created. We will not blame you if your reach exceeds your grasp; if love so ignites your words they go down in flames and nothing is left but their scald. Or if, with the reticence of a surgeons hands, your words suture only the places where blood might flow. We know you can never do it properly once and for all. Passion is never enough; neither is skill. But try. For our sake and yours forget your name in the street; tell us what the world has been to you in the dark places and in the light. Dont tell us what to believe, what to fear. Show us belief s wide skirt and the stitch that unravels fears caul. You, old woman, blessed with blindness, can speak the language that tells us what only language can: how to see without pictures. Language alone protects us from the scariness of things with no names. Language alone is meditation. Tell us what it is to be a woman so that we may know what it is to be a man. What moves at the margin. What it is to have no home in this place. To be set adrift from the one you knew. What it is to live at the edge of towns that cannot bear your company. Tell us about ships turned away from shorelines at Easter, placenta in a field. Tell us about a wagonload of slaves, how they sang so softly their breath was indistinguishable from the falling snow. How they knew from the hunch of the nearest shoulder that the next stop would be their last. How, with hands prayered in their sex, they thought of heat, then sun. Lifting their faces as though it was there for the taking. Turning as though there for the taking. They stop at an inn. The driver and his mate go in with the lamp leaving them humming in the dark. The horses void steams into the snow beneath its hooves and its hiss and melt are the envy of the freezing slaves. The inn door opens: a girl and a boy step away from its light. They climb into the wagon bed. The boy will have a gun in three years, but now he carries a lamp and a jug of warm cider. They pass it from mouth to mouth. The girl offers bread, pieces of meat and something more: a glance into the eyes of the one she serves. One helping for each man, two for each woman. And a look. They look back. The next stop will be their last. But not this one. This one is warmed. Its quiet again when the children finish speaking, until the woman breaks into the silence. Finally, she says, I trust you now. I trust you with the bird that is not in your hands because you have truly caught it. Look. How lovely it is, this thing we have done together.

The Polycystic Ovarian Syndrome Disorder Health And Social Care Essay

The Polycystic Ovarian Syndrome Disorder Health And Social Care Essay Women of all ages have been faced with problems associated with gynecological issues. Particularly young women of childbearing years have dealt with disorders of the reproductive system. These disorders have lead to long term health problems. These disorders involve amenorrhea, infertility, hirsutism, and gargantuan polycystic ovaries. It was not until the 1930s did these problems seem to have a viable solution. Two scientists, Irving Stein and Michael Leventhal unearthed the fact thats when women with these disorders had ovarian biopsies done, they began to menstruate regularly.  [1]   PCOS is defined as an endocrine disturbance that causes primarily anovulation and polycystic ovaries due to the continued stimulation of the ovary by pituitary luteinizing hormone. Its symptoms include infertility, obesity, acne, hirsutism, hair loss, insulin resistance and polycystic ovaries. Other symptoms include decreased sex drive, high cholesterol levels, exhaustion or lack of mental alertness, depression and anxiety, sleep apnea, and thyroid problems.  [3]  However, some of these symptoms such as excess body hair will depend on that particular persons genetic makeup. For example, Asiatic people are not very hairy, so Chinese women with PCOS rarely suffer from this symptom whereas people from the Mediterranean have much more hair, so this is likely to be an indication. PCOS is a hormonal disorder that affects approximately seven percent of all women. In fact it is the most common among women. Its astonishing how often young women are witnessed at medical doctors office with health issues that can be followed back to insulin resistance. Insulin Resistance lies at the core of Polycystic Ovarian Syndrome by averting the efficient conversion of food into energy because cell walls have become de-sensitized to insulin. As a result, insulin levels in the bloodstream become severely unbalanced, leading to an spread in free-floating glucose which is sent to the liver and transformed to excess body fat. These can consequent in weight gain and obesity. Furthermore, insulin resistance can lead to more serious problems such as cardiovascular disease and Type 2 Diabetes.  [4]   Because these symptoms vary so extensively, doctors may still misdiagnose PCOS. In fact eight out of ten women with polycystic ovarian syndrome could have insulin resistance, resulting in higher than normal insulin levels which may act on the ovaries by increasing male hormones.  [5]  Polycystic Ovarian Syndrome is one circumstance seen with increasing rates of reoccurrence. Five to ten percent of women of childbearing age are affected by PCOS. Stein-Leventhal Syndrome can transpire at any age prior to menopause. Women can go months without being diagnosed, because warning signs coincide with so many other womens health issues. PCOS is unknown to some women yet it causes a multiplicity of symptoms that has an impact on female reproductive health in many approaches that can be truly overwhelming. Although PCOS affects the reproductive system, it is imperative to understand that PCOS is an endocrine disorder. Proteins are secreted or released in to the bloodstream promptly. These are known as hormones. Circadian rhythms or the bodys normal, everyday regularity are synchronized by those hormones. Hormonal substances include metabolism of mineral deposits, reactions to stress, sexual performance, reproduction, and management of fluids. Endocrine glands such as pituitary, hypothalamus, thyroid, parathyroid, pancreas and ovaries produce hormones in women. When there are glitches and breakdowns in the hormonal development, the womans body is significantly disturbed. Women with Stein-Leventhal Syndrome have ovaries that created profusion of follicles each month without giving off an egg. PCOS can play a role in irregular periods, excessive weight gain despite the effort of diet and exercise. Acne and excessive facial hair are also caused by the syndrome. It is also the most common cause of infertility in the United States. PCOS is often a short-term, yet in can lead to life-long illnesses. For example, young girls are seen going through puberty when their ovaries are trying to set a regular menstrual cycle. It is also noticed in women during the years of transition to perimenopause. Polycystic Ovarian Syndrome is temporary but can lead to insulin resistance. This leads to nonstop high levels of insulin in the bloodstream. It is possible that this extra insulin glitches onto the receptors lining the ovary and quickens cyst production. This is an issue that should be monitored because women with insulin resistance have a greater risk of developing other serious health problems, like diabetes, heart disease, and metabolic syndrome.  [6]   Many case studies have shown that women from adolescents to adults are not diagnosed until they want to become pregnant or when they have other health issues. Women should be treated as soon as possible particularly when risks are shown such as infrequent menstrual cycles, weight gain, and facial hair. The advantage will be that the risk of long-term health problems such as obesity and diabetes do not occur. Age is not a factor because case studies have shown that girl as young as nine years old have been diagnosed with the Stein-Leventhal Syndrome or Polycystic Ovaries. Regular menstrual periods are vital in order to avoid osteoporosis and sustain the defensive effects of estrogen in a different place body. Therefore more young women should be exposed to polycystic ovarian syndrome so that they can be tested in order to avoid further complications from diseases. Left untreated, PCOS can lead to detriment that occurs with such diseases. Polycystic Ovarian Syndrome is not a disease but a disorder that no one is definite about what causes it in the first place. A disorder is a pathological condition that presents a group of symptoms peculiar to it and that sets the condition apart as an abnormal entity differing from other normal or pathological body states. In short, a disorder is curable through medicine and treatment, whereas a disease is not. Polycystic Ovarian Syndrome is a true illustration of the domino theory, which states that if one act or event is allowed to take place then a series of similar events will follow. PCOS is a curable disorder, leading to other curable disorders then soon falls into the incurable category. It is a chain reaction. Starting with PCOS it continues, causing skin and thyroid disorders and sleep apnea, then it leads to diabetes and cardiovascular disease. It is also important to understand that PCOS causes stress and mental disorders. Polycystic Ovarian Syndrome is more than an endocrine disorder. Also known as the Stein-Leventhal Syndrome, it is a systemic disorder. This means that instead of affecting one somatic part of the body, it affects other systems as well, including the Integumentary System, Central Nervous System, and Lymphatic System. Stein-Leventhal Syndrome goes beyond being a physical condition. It causes emotional and cognitive distress, affecting every aspect of life. As an endocrine disorder, diabetes is the most common occurrence in Polycystic Ovarian Syndrome. In particular, mellitus diabetes is a disorder of carbohydrate metabolism, characterized by hyperglycemia, which is the increase of blood sugar. It is also set apart by glycosuria, which is presence of sugar in the urine. It results from inadequate production or utilization of insulin. The basic cause of diabetes is unknown but direct cause is failure of beta cells of the pancreas to secrete an adequate amount of insulin. Beta cells are cells of islets of the pancreas that secrete insulin. In most instances, diabetes mellitus is the result of genetic disorder, but it may also result from a deficiency of beta cells caused by inflammation, malignant invasion of the pancreas or surgery. In the absence insulin, glycogenesis and glycolysis are inversely affected. It is currently thought that insulin acts primarily at the cell membrane, facilitating transport of glucose into cells. PCOS influences the integumentary system causing alterations in the skin, consisting of the corium and dermis, and epidermis. It is also known for its manipulation on the skin and its appendage, including the hair and nails. Polycystic Ovarian Syndrome is known for causing acne, pimples, and oily skin. Other common conditions include skin tags, which are thick lumps of skin. These lumps darken and thicken around the neck, groin, underarms and skin folds, which can be easily removed by a dermatologist. Approximately half of the women with Polycystic Ovarian Syndrome have a skin crisis, however, only a few of these women will suffer from scalp hair thinning or lost. There are two studies, A Thousand Cases of PCOS (Eden and Warren, 1999) and The Resistant Acne Study (Eden, 1991), that demonstrates vital details. PCOS is commonly found among women with acne, especially severe acne. According to doctors, there seem to be a correlation between excess body hair and blood androgen levels, but little or no evidence to prove the severity of this correlation. Hormonal therapies are effective in treatment of these conditions irrespective of whether or not there is an identifiable hormonal issue.  [7]   Hair is made of Keratin, which is a protein. Hair strands will grow longer and longer as this protein is release into the root of the hair. Hair extends from the sebaceous follicle and each follicle has a growth cycle. Disturbance in androgen-estrogen balance affects the n sebaceous glands, causing acne. Increased secretion of androgens causes an increase in size and activity of the pilosebaceous glands. This causes vitamin deficiencies which trigger problems of the skin. PCOS relationship with the integumentary system explains the relevance of Hirutism. Infertility is the number one cause of women being diagnosed with Polycystic Ovarian Syndrome. Infertility is characterized by the inability or diminished ability to produce offspring. Most factors responsible for infertility includes immature or abnormal reproductive systems, anomalies of other organ in that vicinity, infections, endocrine dysfunction and emotional problems. Studies have shown that the Stein-Leventhal syndrome or PCOS is associated with sleep apnea. Research is now proving that hormone imbalances caused by Insulin Resistance and PCOS predisposes women to additional heath problems. One such problem is Obstructive Sleep Apnea (OSA), the uncontrolled closure of the upper airway which causes one to stop breathing while sleeping. Sleep disorder can therefore, negatively influence and/or slow down the most basic physiological functioning, triggering a ripple-effect throughout the body. Studies show that women with Polycystic Ovarian Syndrome have an exceptionally high risk of sleep apnea. Women are normally not awakened by the repeated nightly episodes, but others awake with the experience of being choked or asphyxiated. Symptoms of Sleep Apnea include chronic loud snoring, gasping/choking episodes during sleep, excessive daytime sleepiness and personality changes.  [8]   Women with PCOS have an exceptionally high risk of sleep apnea. Increased weight and obesity may play a significant role. High Body Mass Index plays a role to an insulin imbalance that results in a flow of problems related to Insulin Resistance, the inability of the body to effectively manage glucose. Because of a series of biochemical errors, insulin is unable to successfully bind to cells, reducing its ability to transfer glucose into those cells to be converted into energy. This causes a buildup of both insulin and glucose in the blood that contributes to the gathering of plaque in blood vessels. Studies also indicate that Insulin Resistance may be a solid risk factor than excessive testosterone in the incidence of PCOS. In a controlled study, women with PCOS were thirty times more likely to suffer from sleep disordered breathing and reported higher frequencies of daytime sleepiness than the control group. Researchers also found that while testosterone levels between the two groups were parallel; their fasting plasma insulin levels were significantly higher, indicating that sleep apnea might suggest an insulin-related endocrine abnormality.  [9]  These findings further confirm the link between PCOS, Insulin Resistance and higher incidences of diabetic conditions.  [10]   Some women who suffer from PCOS also correlates with factors such as high cholesterol. These victims are at a great risk of high LDL levels. This is commonly known as the bad cholesterol. Disregarding this condition can lead to strokes and heart attacks. In addition, women with PCOS frequently obtain low levels of HDL. This is known as the good cholesterol. Low levels of the good cholesterol increase the risk of cardiovascular disease. Hence, the lower the levels of LDL are and the greater the HDL levels are, there is a slim chance of damage to the cardiovascular disease. Women with the Stein-Leventhal Syndrome are almost twice as likely to experience atherosclerosis. It is characterized by a variable combination of changes of the intima of arteries, consisting of the focal accumulation of lipids, complex carbohydrates, blood and blood products, fibrous tissue and calcium deposits, and associated with changes in the media of arteries. Atherosclerotic plaques are of two major types. One is characterized by the prominent proliferation of cells with small accumulation of lipids. The other is distinguished by its makeup of intracellular and extracellular lipid accumulation and a small amount of cellular proliferation. The causes of atherosclerosis are unknown. However, other risk factors include hypertension, cigarette smoking, and stress. Family history also plays an important role. Polycystic Ovarian Syndrome helps contribute to the number one killer of women in the United States, which is coronary heart disease. Continual high levels of insulin are produced in the pancreas. This it is liberated into the circulatory system. These high levels of insulin lead to obesity and hypertension, which are both antecedents of heart disease. As insulin connects to artery walls, it impairs the tissue, causing the primary damage that generates plaque. Hence, having PCOS causes a drastic transformation in the blood lipids and overall health of the cardiovascular system that plays a role in the development of coronary heart disease. Suggestions for reducing heart disease are primarily the same as decreasing insulin resistance. Polycystic Ovarian Syndrome leads to lifelong diseases such as cancer, heart disease, and diabetes. The onset of these diseases only declines the womans health even more and normally leads to her cause of death. There is a strong correlation between the Stein and Leventhal Syndrome and endometrial cancer. There is also a proportional relationship between PCOS and cholesterol levels that can eventually lead to some type of cardiovascular dysfunction. The endometrial cancer is very important when discussing Polycystic Ovaries. The endometrium is the inside layer of the uterus and is made up of tissue that is loaded in blood vessels. Every month the lining of a menstruating woman is developed in arrangement for a potential pregnancy. If a pregnancy does not occur then the lining will shed. Endometrial cancer is developed inside the uterus. As stages develop it broaden beyond the borders of the pelvis. Endometrial cancer usually is curable. However factors such as the stage and outcome of hormones on the cancer can establish each individuals prognosis. Women with the Stein-Leventhal Syndrome do have a greater risk for developing endometrial cancer, while small. The woman is at a greater risk the more irregular or absent her cycle is. During the normal menstrual, the lining of the uterus or endometrium is open to elements like hormones, including estrogen. This causes the lining to proliferate and thicken. When ovulation does not take place, which is usual in PCOS, the endometriun does not shed and is exposed to greater amounts of estrogen, which causes the endometrium to grow much more than normal. This is what enhances the likelihood of cancer cells beginning to cultivate.  [11]   Women with Stein Leventhal Syndrome or Polycystic Ovarian Syndrome experience psychological effects that are minimal while most women may experience moderate to severe effects. Women with this disorder can lead to diseases such as obesity and diabetes which affect the entire body. Depression can also develop in patients with PCOS. Most women who experience PCOS need emotional and social support. This support is needed to deal constructively with the impact that this have on their lives. Studies have shown that a strong network of family and friends is a tremendous asset to have. This network enhances patients with PCOS to strive to win the battle for a healthy lifestyle. The endocrine gland relative to the hormone issue can cause depression to evolve. PCOS causes a decrease of vital function causing mental depression characterized by altered moods. Significant weight gain usually occurs with PCOS and sometimes worthlessness, self-reproach or excessive guilt. For example, women may feel guilt or distressed when they are unable to produce offspring or they are infertile. Stress can occur when demands of Polycystic Ovarian Syndrome are placed for a woman to adjust or adopt. Stress is a major risk factor for illnesses and diseases. The body reacts to stress in a series of stages known as the general adaptation syndrome (GAS), which involves three stages: alarm, resistance, and exhaustion. Studies show that stress lowers the bodys resistance to disease by weakening the immune system. Events seem to be more stressful when they involve pressure, a lack of control, unpredictability, and intense or repeated emotional shocks. Stress is intensified when a situation is perceived as a threat and when a person does not feel competent to cope with it. The bodys reactions to stress can directly damage internal organs and stress impairs the bodys immune system, increasing susceptibility to disease. The impact of life changes on long range susceptibility to illness. Intense or prolonged stress may cause damage in the form of psychosomatic problems, including heart attacks, strokes, etc. Stress is often the start Insulin Resistance, which contributes to Polycystic Ovarian Syndrome. More insulin is secreted when women eat foods that are high in sugar, fat, and carbohydrates. As sugar or glucose levels ascend in reply to stress, they fuel the production of insulin. This has a large amount of depressing affects. It uphold the synthesis of cholesterol, which a cause dysfunction of the kidneys and high blood pressure. Furthermore, hormones used to respond to excess insulin, such as noradrenalin, are stress-related chemicals that are responsible for raising blood pressure and storing fats. In addition to stress factors, Polycystic Ovarian Syndrome is deeply linked to pathophysiology , Alzheimers disease, indications of depression and other mental disorders. The evidence underlying the theory of Alzheimers disease includes neuro-endocrine conditions described in both disorders and test show that increased levels of glucose in the blood stream and decreased cerebral blood flow in specific areas of the brains of patients put them at risk for Alzheimers disease. Scientists also found that Alzheimer patients had better memory after increased doses of glucose in the blood stream. Women with Polycystic Ovarian Syndrome experience depression and mood swings. A study found that women with PCOS are more likely to develop depression or depressive symptoms. This may have some relationship with the psychological and metabolic effects of obesity. Depression is a severe mood disorder which may or may not affect the way that people function in their daily life.  [12]  These functions include difficulty with sleeping, changes on eating habits, lost of interest in sex and activities and physical pains. Further research is needed but since there has been some studies that linked depression to Diabetes, thus to Polycystic Ovarian Syndrome. Diabetic women who have twice the risk of being depressed have shown improvement when they received therapy. Natalie Rasgons study showed that women with PCOS are depressed not just only because of the symptoms but also because of underlying biology. Proper management of polycystic ovary syndrome primarily concentrates on each womans main concerns. Each womans symptoms differ, so it ranges from indications such as infertility, hirsutism, acne or obesity. Long term, which is the most important aspect of treatment, is managing cardiovascular risks such as obesity, high blood cholesterol, diabetes and high blood pressure. Other symptoms need to be rid as well such as depression, stress, and mental or emotional disorders. Treatment options vary based on the doctor and patient. Often times, the diagnosis is solved by simple methods but sometimes the solution or treatment is complex. Many times oral contraceptives are prescribed because they are effective for regulating menstrual cycles. It is also known for the reduction of male hormones and minimizing the risks of uterine cancer. Weight lost diets and other ovulation medications are recommended for treatment. The most common treatment for Polycystic Ovarian Syndrome is oral contraceptives, also known as birth control pills. Oral contraceptives help maintain periods, a reduced amount of unwanted hair, clearer skin, and other therapeutic benefits. Oral contraceptive pills can help to normalize the menstrual period in order that the cycle comes about every twenty eight days. Normally, the pill causes lighter cycles as well. Oral contraceptive pills can lower androgen hormone levels and lessen the amount of excess hair growth, or hirsutism. It can take six months before there is a decrease in unwanted hair on the face, chest, back and stomach. Oral contraceptive pills can improve acne. The hormones in most types of the Pill can help stop acne from forming. Because there is less menstrual bleeding with the use of oral contraceptive pills, women taking the Pill are less likely to become anemic. Oral contraceptive pills also decrease your chance of getting endometrial (lining of the uterus) cancer, ovarian cancer, and ovarian cysts, which are all factors of Polycystic Ovarian Syndrome. A recent study uncovered another treatment for Polycystic Ovarian Syndrome. There was a case where a 35 year old woman was suffering from Amenorrhea, acne on the face and chest, and habitual abdominal pain. She was diagnosed with Polycystic Ovaries. Her doctor prescribed D-pinitol with a dosage of 600mg twice a day. The prescribed D-pinitol supplement resulted in normal menstruation and resolved the acne and abdominal pains. D-pinitol or 3-O-methyl-D-chiro-inositol is also found in foods such as legumes and citrus fruits as an effective supplement for the treatment of PCOS.(Gaby,2009) D-Pinitol can develop glucose metabolism and help intensify cellular energy. Furthermore, its increase prolongs energy output by improving glucose metabolism. In other words, this medication mimics the hormone insulin. Thus, this medicine can regulate insulin levels, prohibiting the trigger of Diabetes and other metabolic factors.  [13]   Losing weight is also a well-known solution that reduces certain hormones that curb or eliminate the projection of male hormones. Progestins (synthetic progesterones) which increase ovulation are often used to decrease certain hormones. Insulin-sensitizing anti-diabetic drugs can be used to decrease the presence of Stein Leventhal Syndrome or PCOS. Anti-androgens are used to stop the androgen increase which is a form of a male hormone. Treatment or non-treatment may have psychological effects. In order to take control of weight, it is suggested to choose nutritious, high-fiber carbohydrates instead of sugary or refined carbohydrates. Also, it is necessary to balance carbohydrates with protein and healthy fats. One should eat small meals and snacks throughout the day instead of large meals. Most importantly, exercising regularly will help manage insulin levels and weight levels. Other solutions to PCOS include non-steroidal agents, such as Clomiphene and Gunastotropin, which are used to stimulate ovulation in women who have potentially functioning pituitary and ovarian systems. Women treated with this medicine who become pregnant have an increased incidence of multiple births. Gunastotropin is a hormone produced by the fetal placenta that maintains the function of the corpus luteum. The purpose of the hormone is to induce ovulation in infertility that is caused by in adequate stimulation of the ovary by endogenous gunastotropic hormones. These are hormones produced by anterior lobe of the hypophysis, which includes the follicle-stimulating hormone and the luteinizing hormone.  [14]   Herbs and Vitamins are also considered in order to promote a more natural approach to treat Polycystic Ovarian Syndrome. Chromium, B vitamins, Zinc and Magnesium are just some of the vitamins that are affected by Polycystic Ovarian Syndrome and are needed to maintain a healthy body and lifestyle. For example, Magnesium levels have been found to be low in people with diabetes and there is a strong link between magnesium deficiency and insulin resistance. It is, therefore, an important mineral to include when Polycystic Ovarian Syndrome is involved. Chromium is an extremely important mineral when discussing PCOS. It helps to encourage the formation of glucose tolerance factor which is a substance released by the liver and required to make insulin more efficient. A deficiency of chromium can lead to insulin resistance, which is a key problem in the case of PCOS; too much insulin can be circulating but it is unable to control blood sugar levels. Chromium is the most widely researched mineral used in the treatment of overweight. It helps to control cravings and reduces hunger. Chromium also helps to control fat and cholesterol in the blood. Vitamins B2, B3, B5 and B6 are particularly useful for controlling weight. Vitamin B2 helps to turn fat, sugar and protein into energy. B3 is a component of the glucose tolerance factor, which is released every time blood sugar rises, and vitamin B3 helps to keep the levels in balance. Vitamin B5 has been shown to help with weight loss because it helps to control fat metabolism. B6 is also important for maintaining hormone balance and, together with B2 and B3, is necessary for normal thyroid hormone production. Any deficiencies in these vitamins can affect thyroid function and consequently affect the metabolism. The B vitamins are also essential for the liver to convert your old hormones into harmless substances, which can then be excreted from the body. Zinc is an important mineral for appetite control and a deficiency can cause a loss of taste and smell, creating a need for stronger-tasting foods, including those that are saltier, sugary and/or spicier often more fattening, Zinc is also necessary for the correct action of many hormones, including insulin, so it is extremely important in balancing blood sugar. It also functions together with vitamins A and E in the manufacture of thyroid hormone.  [15]   Polycystic Ovarian Syndrome, also known as PCOS and the Stein-Leventhal Syndrome is one of the most perilous of endocrine and hormonal disorders that a woman can undergo. It inflicts disorder in a number of vicinities of the human body. It varies from infertility and skin conditions to Insulin Resistance and Diabetes. These instances lead to a number of cardiovascular diseases. Polycystic Ovarian Syndrome is depicted by excessive high levels of insulin initiated by Insulin Resistance. This is a circumstance that stops the effective change of food into energy, simply because it causes the cell wall to be negligent toward insulin. Insulin allows sugar, or glucose to permeate the cell wall and be transformed into energy. Instead of the insulin going through the cell wall, it stays there allowing a large amount of insulin to penetrate into the bloodstream. This will inflate hormone stages to an extent to where it causes the woman to be really unhealthy. When this occurs, glucose, or blood sugar, stays in the blood stream, which make its high levels be transported to the liver. When the sugar makes it to the liver, it is then turned into fat and stored all over the body. In essence, this course of action leads to obesity and weight gain. Insulin that floats freely in the body can clog the lining of the arteries, which causes atherosclerosis. It is depicted as a harmful upsurge that proliferate the danger to the cardiovascular system, allowing strokes and heart attacks to occur. The extreme, unnecessary amounts of insulin levels that are related to Polycystic Ovarian Syndrome also arouse the ovaries to release irregular levels of testosterone. These are particularly male hormones that can stop the ovaries from secreting an egg each month. This causes the woman to be infertile, or unable to conceive children. Women who suffer from the Stein-Leventhal Syndrome also have a higher risk of getting diabetes. The development of diabetes increases womens chance of having cardiovascular disease. Researchers have proved that women with Polycystic Ovarian Syndrome have a much greater risk of developing heart trouble than women who do not have it. When testosterone levels are at its peak, women with the Stein-Leventhal Syndrome have excessive hair growth or increasingly male features. Testosterone levels affect patterns of baldness and other conditions such as acne. Obesity is a huge fundamental cause of Polycystic Ovaries. Stress develops in the cardiovascular system when weight increases. The weight gain causes the lungs and the heart to work harder in order that there is a sufficient amount of blood throughout the body that is oxygenated. Also, an increase in LDL, which is bad cholesterol and low levels of good cholesterol, HDL, amplifies the risk of heart attack and stroke. Because of the variety of possible symptoms, diagnosis can be a complex and lengthy proce

Technological Advancement in Faust, Accident, Life of Galileo, Oppenheimer, and The Physicists :: Faust Essays

The Cost of Technological Advancement Exposed in Faust, Accident, Life of Galileo, Oppenheimer, and The Physicists  Ã‚  Ã‚     Ã‚  Ã‚   Since the beginning of time, man has taken every step possible to advance technology.   Advancements in medicine, aviation, science, and other areas, have made our world a better place to live.   But there have also been technological developments that perhaps have hurt mankind far greater than any benefit that they have provided. Through their works, five German authors present readers with a very difficult question: Is the technology really worth it?   These authors present many common themes.   In this essay I will discuss these themes and how they relate to the social cost of advancing technology.   Ã‚  Ã‚  Ã‚   The first play that I read this past semester was Goethe’s â€Å"Faust.†Ã‚   This play is centered around the life of the scientist and doctor, Faust.   Faust is a very intelligent man who has excelled in life as a scientist and a doctor.   Though everyone looks up to him and thinks he is a great man, he still thinks that he does not know enough.   He believes that every bit of knowledge that there is to be attained must be attained.   This belief coupled with the unhappiness he possesses with life leads him to make the ultimate decision which, in turn, ruins both his life and the life of others, all because he was selfish, and wanted to know it all and couldn’t do it on his own.   Faust made a bet with Mephistopheles, the devil.   This bargaining with the devil is something that the mind should never know about.   Two people ended up dying because of the involvement Faust played in their lives because of this little bet that he mad e with Mephisto.   And the only question that can be asked is â€Å"was it really worth watching others die just so he could be happy?†Ã‚   And the answer is no.   He saw the woman he loved and her brother die before him because of his selfishness, his desire to milk life and knowledge for all that they were worth.   And what did Faust gain?   In my opinion, nothing.   He only lost.   Some things in the world are worth knowing.   Some things are even worth going to extremely great ordeals to know them.   But in Faust’s case, he was childish, immature, and selfish.   He became so depressed and had to know more, even though most people would have killed to be as fortunate as he was.

Unzipped :: Free Essay Writer

Unzipped In the expository text Unzipped- everything teenagers want to know about love, sex and each other, Bronwyn Donaghy has written about the facts and consequences of teenage sex. By doing so she has presented us with her old fashioned ideologies and her strong ‘anti-teenage-sex’ values and attitudes. As the audience Donaghy has tried to scare us into believing and following these attitudes, which are very evident throughout the entire text. Virginity and abstinence is the way to go. This text is targeted at young youths who are curious and want to explore their sexuality and their parents who Donaghy thinks should be open and willing to educate their children on the subject. In order to do this she has employed the use of three different writing styles: These being narrative, expository and real life accounts. Between chapters and further the different sexual topics, Donaghy has split the information up by an ongoing fictional story, which runs through the entire book. It is a narrative story about two inquisitive and curious adolescent teenagers who fall in love and start to get ‘full on’ but then decide against the idea of sex as it is simply too complicated. Donaghy has done this by using very ‘down to earth’ language that she thinks teenagers can relate to and a simplistic story line. However by trying to relate to teenagers at what she perceives is their level in my opinion gives the story very little realism in regards to reality as she simply cant ‘pull it off’. The story is made to almost look superficial. Within the story it is made very clear that abstinence is the way to go, reflect Donaghy’s ideologies. As the writer she does not even try to hide this attitude of hers and at one stage, through Ben’s mum is able to vocalise th is: ‘ Love is a wonderful thing†¦. Sex on the other hand, can be very dangerous in the hands of the young and inexperienced.’ She then goes on to say: I sincerely hope you wont’. This is in relation to Ben and Lucy’s sex life. By creating this story Donaghy tries to manipulate us as the audience to accept these ideas and her values as being right. To further shape our response towards this very strong attitude Lucy and Ben adhered to Ben’s mum’s opinion and further Donaghy’s ideologies. She developed these characters in order to express her perception of what teenage relationships should be like in her eyes.

Psychological Conflicts In Literature(1) :: essays research papers

We all experience psychological conflicts, knowingly or unknowingly. They involve psychological conflicts among our thoughts, emotions, and rational thinking. It may be the most dangerous conflict of all due to the battleground in which it take place in -- our mind. There are many examples of psychological conflicts in the stories we have read. In "Leiningen Versus the Ants" by Carl Stephenson, Leiningen battled not only on his South American plantation, but in his mind. He struggled with the issue of running away and letting the ants take over his plantation. He wasn't a quitter and enjoys the mental aspects of things. But when the ants and the reality of death came, he had to resolve the conflict whether to stay or flee. This was especially true when he ran to the dam wheel. He could of fled then or died, but he chose to try to save the plantation and workers. He was faced with the conflict living or, perhaps the greatest psychological conflict, which he resolved when he chose to run to the wheel. In "The Contents of the Dead Man's Pockets" by Jack Finney, Tom also faced a psychological conflict. The story was mainly focused on his physical conflict, but near the end he experienced psychological conflict. As with Leiningen, Tom faced the choice to die or to live, and he realized with that conflict how much his wife meant to him. He overcame the conflict when, as we read, the yellow paper flew out the window again, but he left to be with his wife. In "Blues Ain't No Mockin'bird" by Toni Cade Bambara, Granny experienced a psychological conflict with her past treatment and her current conflict with Smiley and Camera. She struggled to break and maybe actually kill them or fall into depression, but she was successful in winning the conflict.

7) Data from a small bookstore are shown in the accompanying table. The manager wants to predict Sales from Number of Sales People Working. Number of sales people working| Sales (in $1000)| 4| 12| 5| 13| 8| 15| 10| 16| 12| 20| 12| 22| 14| 22| 16| 25| 18| 25| 20| 28| x=11. 9| y=19. 8| SD(x)=5. 30| SD(y)=5. 53| a) Find the slope estimate, b1. Use technology or the formula below to find the slope. b1=rsysx Enter x,y Data in TI-84 under STAT > STAT > CALC > 8: LinReg(a+bx) b1=1. 023 b) What does b1 mean, in this context?The slope tells how the response variable hanges for a one unit step in the predictor Thus, an additional; $1,023 of sales associated with each additional sales person working. c) Find the intercept, b0. b0=y-b1x =19. 8-1. 023(11. 9) For this problem, use technology, rounding to three decimal places. b0=7. 622 d) What does b0 mean in this contet? Is it meanful? The intercept serves as a starting value for the predicitons. It shuld only be interpreted if a 0 value for the predictor variable makes sense for the context of the situation. On average, $7,622 is expected when 0 sales people are working.It is not meaningful because it does not make sense in this context. e) Write the equation that predicts Sales from Number of Sales People Working. Recall that the slope of the equation b1=1. 023 and the intercept is b0=7. 622 Complete the equation. Sales=7. 622+1. 023 *(Number of Sales People Working) f) If 19 people are working, what sales do you predict? Substitute 19 for the number of sales people working in the equation found in the previous step and solve for Sales. Sales=7. 622+1. 023 *(Number of Sales People Working) =7. 622+1. 023*19Substitute. =27. 059Simplify. *Note that each unit of Sales represents $1000. Thus, the predicted sales for 19 people working is 27,059 dollars. g) If sales are actually $26,000, what is the value of the residual? Subtract the predicated value found in the previous step from the actual value. 26,000-27,059=-1059 Thus, t he value of the residual is -1059 dollars. h) Have the sale been overestimated or underestimated The predicted sales are $27,059 and the actual sales are $26,000. Since $27,059 > $26,000, the sales were overestimated. 13) Of the 46 individuals who responded, 25 are concerned, and 21 are not concerned. of those concerned about security are male and 5 of those not concerned are male. If a respondent is selected at random, find each of the fallowing conditional probabilities. | Male| Female| Total| Concerned| 9| 16| 25| Not Concerned| 5| 16| 21| Total| 14| 32| 46| a) The respondent is male, given that the respondent is not concerned about security. P(Male|Not Concerned) = 521 = 0. 238 b) The respondent is not concerned about security, given that is female P(Not Concered|Female) = 1632 = 0. 500 c) The respondent is female, given that the respondent is concerned about security. P(Female|Concerned) = 1625 = 0. 40 14) It was found that 76% of the population were infected with a virus, 21% were without clean water, and 18% were infected and without clean water | Clean Water| | | Yes| No| Total| Infected| 0. 58| 0. 18| 0. 76| Not Infected| 0. 21| 0. 03| 0. 24| Total| 0. 79| 0. 21| 1. 00| a) What’s the probability that a surveyed person had clean water and was not infected? .21 had clean water and was not infected 15) A survey concluded that 54. 4% of the households in a particular country have both a landline and a cell phone, 32. 6% have only cell phone services but no landline, and 4. 6% have no telephone services at all. ) What proportion of households have a landline? Begin by making a contingency table. | Cell Phone| | | Yes| No| Total| Landline| 0. 545| 0. 083| 0. 628| No Landline| 0. 326| 0. 046| 0. 372| Total| 0. 871| 0. 129| 1. 00| The completed contingency tables shows that P(landline) = 0. 628. b) Are having a cell phone and having a landline independent? Explain. Events A and B are independent when P(B|A) = P(B). To determine wheter having a cell pho ne and having a landline are indepented, find P(landline|cell phone) and P(landline). Recall from part a) that P(landline) =0. 628 PBA=P(A and B)P(A)Use the formula to find P(landline|cell phone) Plandlinecell phone=P(landline and cell phone)P(cell phone) Since the contingency table shows that P(landline and cell phone)=0. 545 and P(cell phone)=0. 871, substitute these values into the equation. Divide to find the conditional probability, rounding to three decimal places. Plandlinecell phone=0. 5450. 871=0. 626 Thus, P(landline|cell phone)=0. 626 and P(landline)=0. 628. Because 0. 626 is very close to 0. 628, having a cell phone and having a landline are probably independent. Of the households surveyed, 62. 6% with cell phones had landlines, and 62. 8% of all households did. 6) A marketing agency has developed three vacation packages to promote a timeshare plan at a new resort. They estimate that 30% of potential customers will choose the Day Plan, which does not include overnight ac commodations; 30% will choose the Overnight Plan, which includes one night at the resort; and 40% will choose the Weekend Plan, which includes two nights. a) Find the expected value of the number of nights that potential customers will need Vacation Package| Nights Included| Probability P(X=x)| | Day Plan| 0| 30100=0. 3| | Overnight Plan| 1| 30100=0. 3| | Weekend Plan| 2| 40100=0. 4| | This, P(X=0)=0. 3, P(X=1) =0. 3, and P(X=2)=0. Use the formula E(X) = ? x †¢ P(x) to detrime the expected value. E(X) = ? x †¢ P(x) = 0(0. 3) +1(0. 3) +2(0. 4) = 1. 1 There, the expected value of the number of night potential customers will need is 1. 1 b) Find the standard deviation of the number of nights potential customers will need. The standard deviation is the square root of the variance. First, Find the Variance: To do so, find the deviation of each value of X from the mean and square each deviation. The variance is the expected value of these squared deviations and is found using th e formula below. = Var(X) = ? (x –  µ)? P(x) Find the deviation for each value of X.Remember that E(x)=1. 1 Vacation Package| Nights Included| Probability P(X=x)| Deviation (x – E(X))| Day Plan| 0| 30100=0. 3| 0 – 1. 1 = -1. 1| Overnight Plan| 1| 30100=0. 3| 1 – 1. 1 = -0. 1| Weekend Plan| 2| 40100=0. 4| 2 – 1. 1 = 0. 9| Now find the variance using the formula =Var(X)=? (x –  µ)? P(x) Var(X) = ? (x –  µ)? P(x) = (-1. 1)? (0. 3) + (-0. 1)? (0. 3) + (0. 9)? (0. 4) = 0. 69 Finally, the standard deviation also known as ? is the square root of the variance. ? = Var(x) = 0. 69 = 0. 83 Therefore, the standard deviation of the number of nights potential customers will need is approximately 0. 83 nights. 7) A grocery supplier believes that in a dozen eggs, the mean number of broken eggs is 0. 2 with a standard deviation of 0. 1 eggs. You buy 3 dozen eggs without checking them. a) How many broken eggs do you get? The expected value of t he sum of random variables is the sum of the expected values of each idividula random variable. Find the sum of the expected values where X is the total number of broken eggs in the three dozen, and X, X, X Represent the three individual dozen eggs. E(X) = E(X1) + EX2+ EX3 = 0. 2 + 0. 2 + 0. 2 = 0. 6 Therefore, the expected value of X is 0. 6 eggs. b) What’s the standard deviation?The variance of the sum of independent variables is the sum of their individual variances. Find the variance for each carton, add the variances, and then take the square root of the sum to find the standard deviation. The variance of each individual dozen is the square of each dozens standard deviation. Var(X1) = Var(X2) = Var(X3) = 0. 12= 0. 01 Find the sum of the variances to find the variance of the sum. Var(X) = VarX1+ VarX2+ VarX3 = 0. 01 + 0. 01 + 0. 01 = 0. 03 Recall that the standard deviation is the square root of the variance. Find the standard deviation. SD(X) = Var(x) = 0. 03 = 0. 17Ther efore, the standard deviation is 0. 17 eggs c) What assumptions did you have to make about the eggs in order to answer this question? The variance for the sum of random variables is only the sun of variances of each random variable in certain cases. Review the assumption that must be made to allow the variance to be the sum of the individual variances. 18) An insurance company estimates that it should make an annual profit of $260 on each homeowner’s policy written, with a standard deviation of $6000. a) Why is the standard deviation so large? Home insurance is used to protect the owner financially in the event of a problem.If a catastrophe occurs, then the insurance company will cover the cost of the damage. If a catastrophe never occurs, then the insurance company pays nothing. Meanwhile, the owner pays the insurance company at regular intervals whether or not a catastrophe occurs. The expected value is the mean annual profit on all of the policies and the standard deviatio n is a measure of how much annual profits can differ from the mean. Use this information with the fact that claims are rare, but very costly, occurrences. b) If the company writes only four of these policies, what are the mean and standard deviation of the annual profit?LetX1,X2, X3,†¦,Xn represent the annual profit on the n policies and let X be the random variable for the total annual profit on n polices written. X=X1+X2+ X3+†¦+Xn The expected value of the sum is the sum of the expected values. Find the expected value of the annual profit on each policy. EX1=EX2=EX3=EX4=$260 Now find the sum of the expected values. EX=EX1+EX2+EX3+EX4 =260+260+260+260 = $1040 Therefore, the mean annual profit is $1040 To find the standard deviation of the annual profit, use the fact that te variances of the sum of independent variables is the sum of their individual variances. First find the variance for each policy.The variance for the policy is the square of the standard deviation. VarX 1=VarX2=VarX3=VarX4=60002=36,000,000 VarX=VarX1+VarX2+VarX3+VarX4 = 4(36,000,000) = 144,000,000 Evaluate the square root of the variance to find the standard deviation. SDX=VarX =144,000,000 =$12,000 Therefore, the standard deviation is $12,000 c) If the company writes 10,000 of these policies, what are the mean and standard deviation of annual profit? The expected value of the sum is the sum of the expected values. The expected value of each policy was found earlier. EX1=EX2=EX3=†¦ =EX10,000=$260 Now find the sum of expected values. EX=EX1+EX2+EX3+†¦ +EX10,000 10,000(260) =$2,600,000 Therefore, the mean annual profit is $2,600,000 To find the standard deviation of the annual profit, use the fact that the variance of the sum of independent variables is the sum of their individual variances. First find the variance for each policy. The variance for the policy is the square of the standard deviation and was found earlier. VarX1=VarX2=VarX3= †¦ =VarX10,000=36,000,000 Now sum the variances to find the variances of the sum. VarX=VarX1+VarX2+VarX3+†¦ +VarX10,000 =10,000(36,000,000) =360,000,000,000 Evaluate the square root of the variance to find the standard deviation. SDX=Var(X) =360,000,000,000 $600,000 Therefore, the standard deviation is $600,000. d) Do you think the company is likely to be profitable? Recall that the mean annual profit for 10,000 policies is $2,600,000. While this number seems quite large, it is necessary to determine how likely a profit is to ensure that this company will be profitable. Find the distance in standard deviation of $0 from the mean to determine how rare an occurrence of no profit would be. z=x- =0-2,600,000600,000 =-4. 3 Thus, $0 is 4. 3 standard deviation below the mean. **Note that approximately 95% of the annual profits should lie within two standard deviations of the mean.Evaluate whether the distance of $0 from the mean is convincing enough to determine whether or not the company will be profitable. e) W hat assumptions underlie your analysis? Can you think of circumstances under which those assumptions might be violated? The variance of the sum of random variables is only the sum of the variances of each random variables in certain cases. Review the assumption that must be made to allow the variance to be the sum of the individual variances. Then chose the situation that would create an association among policy losses. 19) A farmer has 130 lbs. of apples and 60 lbs. f potatoes for sale. The market price for apples (per pound) each day is a random variable with a mean of 0. 8 dollars and a standard deviation of 0. 4 dollars. Similarly, for a pound of potatoes, the mean price is 0. 4 dollars and the standard deviation is 0. 2 dollars. It also costs him 5 dollars to bring all the apples and potato’s to the market. The market is busy with shoppers, so assume that he’ll be able to sell all of each type of produce at the day’s price. a) Define your random variables, and use them to express the farmer’s net income. A random variable’s outcome is bases on a random event.Therefore let the random variables represent the factors that will be randomly determined each day. The random variables should represent the market prices of the two items. A = price per pound of apples P = price per pound of potatoes The profit is equal to the total income minus the total cost. The income is found by multiplying the market price for apples by the total number of pounds sold and adding it to the product of the market price for potatoes and the number of pounds of potatoes sold. The total cost is the transparent cost. Profit = 130A + 60P – 5 b) Find the mean. The mean of the net income is the expected value of the profit.Profit = 130A + 60P – 5 E(Proft) = E(130A + 60P – 5) Use the property E(X + Y) = E(X) + E(Y) to express the expected value of the profit as the sum of two separate expected values E=(Profit) = E(130A +60P -5) = E [(130A) + (60P – 5)] = E(130A) + E(60P – 5) Now use the property EX ±c= E(X) ±c E(Profit) = E(130A) + E(60P – 5) = E(130A) + E(60P) – 5 Finally, use the property E(aX) = aE(X) to remove the coefficient from the expected values. E(Profit) = E(130A) + E(60P) – 5 = 130E(A) + 60E(P) – 5 Substitute the known expected values of the prices of apples and potatoes in the equation. E(Profit) = E(130A) + E(60P) – 5 E(0. 8) + E(0. 4) – 5 Evaluate the expected profit. E(Profit) = 130(0. 8) + 60(0. 4) – 5 = 123 Therefore, the mean is 123 dollars. c) Find the standard deviation of the net income. To find the standard deviation, first find the variance and then take the square root, since the properties useful in this case are in terms of variance and not standard deviation SD(Profit) = Var(Profit) = Var(130A+60P-5) First use the property Var(X + Y) = Var(X) + Var(Y) to express the variance of the profit as the sum of two separate v ariance Var(Profit) = Var(130A + 60P – 5) = Var[(130A) + (60P – 5)] =Var(130A) + Var(60P – 5)Now use the property Var(X  ± c) = Var(X) to simplify the second variance Vr(Profit) = Var(130A) + Var(60P – 5) = Var(130A) + Var(60P) Finally, use the property VaraX=a2VarX to restate each variance. Var(Profit) = Var(130A) + Var(60P) = 1302VarA+ 602VarP = 16,900Var(A) + 3600Var(P) Evaluate the variance of the profit. Var(Profit) = 16,900(0. 16) + 3600(0. 04) = 2848 Lastly, find the standard deviation, rounding to two decimal place. SD(Profit) = VarProfit = 2848 = 53. 37 Therefore, the standard deviation of the net income is 53. 37 dollars. d) Do you need to make any assumptions in calculating the mean?Recall that the mean of the sum of two or more random variables is the sum of the means. Determine what, if any, assumptions are made to use this property. Do you need to make any assumptions in calculating the standard deviation? Recall that the variance of the s um of two random variables is only the sum of their individual variances in certain cases, Determine what, if any, assumptions are made to use this property. 20) A salesman normally makes a sale (closes) on 65% of his presentations. Assuming the presentations are independent, find the probability of the following. ) He fails to close for the first time on his sixth attempt. Use the formula below to determine the probability, where p is the probability success, q=1 – p and X is the number of trails until the first success occurs. P(X=x) = qx-1p Find the values for p and q. **Note that in this case that a success is defined as failed to close p = 0. 35 q = 0. 65 Substitute and solve to find P(X=6). Rounding to four decimal places P(X=6) = qx-1p = 0. 656-1(0. 35) = 0. 0406 Therefore, the probability he fails to close for the first tie on his sixth attempt is 0. 0406 b) He closes his first presentation on his fifth attempt.Find the values for p and q. **Note that in this case tha t a success is defined as making a sale p = 0. 65 q = 0. 35 Substitute and solve to find P(X = 5), rounding to four decimal places P(X=5) = qx-1p = 0. 355-1(0. 65) = 0. 0098 Therefore, the probability he closes his first presentation on his fifth attempt is 0. 0098 c) The first presentation he closes will be on his second attempt. Find the values for p and q. Note that in this case that a success is defined as making a sale. p = 0. 65 q = 0. 35 Substitute and solve to find P(X=2) P(X=2) = qx-1p = 0. 352-1(0. 65) = 0. 2275Therefore, the probability the first presentation he closes will be on his second attempt is 0. 2275 d) The first presentation he closes will be on one of his first three attempts. Use the fact that the compliment of an even is equal to 1 – P(X=x) to find the probability. The compliment event is that he will not close a sale on any of his first three attempts. Find the probability that he does not close on his first three attempts, rounding to four decimal pl aces. 0. 353=0. 0429 Subtract from 1 to find the probability the first presentation he closes will be on one of his first three attempts 1 – 0. 429 = 0. 9571 Therefore, the probability the first presentation he closes will be on one of his first three attempts is 0. 9571 21) College students are a major target for advertisements for credit cards. At a university, 73% of students surveyed said that they had opened a new credit card account within the past year. If that percentage is accurate, how many students would you expect to survey before finding one who had not opened a new account in the past year? First check to see that the cells are Bernoulli trials. Trials are Bernoulli if the following three conditions are satisfied. 1.There are only two possible outcomes (called success and failure) for each trial. 2. The probability of success, denoted p, is the same on every trial. (The probability of failure, 1 – p is often denoted q. ) 3. The trials are independent Ther e are only two possible outcomes for each trial because a student either opened a credit card account in the past year or they did not. The probability of success is the same on every trial, based on the percent given in the problem statement. The trails are independent because each student’s response is not dependent on any other student’s response.Thus, the trials of surveying the students are Bernoulli trials. A geometric probability model models how long it will take to achieve the first success in a series of Bernoulli trials. Let X be the number of students that will have to be surveyed before finding the first student who did not open a credit card in the past year. The two outcomes are a student who did not open a credit card account in the past year *success) and a student who opened a credit card account in the past year (failure). The probability of a failure is given in the problem statement as q = 73% = 0. 73.Find the probability of success by subtracting this from 1. P = 1 – 0. 73 = 0. 27 Find the expected value of X. In a geometric model, the expected value is EX= 1p , where p is the probability of success. Round up to the nearest integer. EX=10. 27=4 Therefore, on average, you would expect to survey 4 students before finding one who had not opened a new account in the past year. 22) A certain tennis player makes a successful first serve 82% of the time/ Assume that each serve is independent of the others. If she serves 7 times, what’s the probability she gets a) all 7 serves in? b) exactly 5 serves in? ) at least 5 serves in? d) no more than 5 serves in? The first step is to check to see that these are Bernoulli trails. The first serves can be considered Bernoulli trials. There are only two possible outcomes, successful and unsuccessful. The probability of any first serve being good is given as p = 0. 82. Finally, it is assumed that each serve is independent of the others. Next define the random variable. Each questi on deals with the number of serves, so let X be the number of successful serves in n = 7 first serves. Now determine which probability model is appropriate for these problems.Recall that geometric probability models deal with how long it will take to achieve a success. A binomial probability model describes the number of successes in a specific number of trails. All the question deal with the number of successful serves so the binomial probability model Binom(7,0. 82 is appropriate here. a) all 7 serves in? The probability that she ges all 7 serves in is P(X=7). To use the binomial probability model Binom(n,p), use the fallowing formula, where n is the number of trials, p is the probability of success, q is the probability of failure (q = 1 – p), and X is the number of successes in n trials.PX=x= nxpxqn – x, where nx= n! x! n-x! First substitute the correct values into the formula PX=7= 770. 8270. 187- 7 Now simplify. P(X = 7) ? 0. 249 Therefore, the probability that s he gets all 7 serves in is approximately 0. 249 binomPDF(7, . 82, 7) = b) exactly 5 serves in? The probability she gets exactly 5 serves in is P(X = 5). As in part a, use the formula PX=x= nxpxqn – x to find this probability PX=5= 750. 8250. 187 – 5 ?0. 252 Therefore, the probability she gets exactly 5 serves in is approximately 0. 252 binomPDF(7, . 82, 5) = c) at least 5 serves in?To find P(at least 5 serves in), first determine and an expression that is equal to this probability. Note that the wording â€Å"at least 5†, means 5 or more, meaning that there can 5, 6, or 7 serves in. Thus, the probability equals P(X=5) + P(X=6) + P(X=7). So to find the probability that she got at least 5 serves in, evaluate. P(X=5) + P(X=6) + P(X=7) = 75(0. 82)50. 187-5+76(0. 82)6(0. 18)7-6+77(0. 82)7(0. 18)7-7 ?0. 885 Therefore, the probability she gets at least 5 serves in is approximately 0. 885 binomPDF(7, . 82, 5) + binomPDF(7, . 82, 6) + binomPDF(7, . 82, 7) = d) no more th an 5 serves in?To find P(no more than 5), first determine an expression that is equal to this probability. Note that the wondering â€Å"no more than 5† means 5 or less, meaning that there can be 0 thru 5 successful serves. Thus, the probability equals P(X? 5). So to find the probability that there are no more than 5 serves in, evaluate P(X? 5), which is equal to P(X=0) + P(X=1) + †¦ + P(X=5), using the formula PX=x= nxpxqn – x P(X=0) + P(X=1) + †¦ + P(X=5) = 70(0. 82)00. 187-0+71(0. 82)1(0. 18)7-1 + †¦ + 75(0. 82)5(0. 18)7-5 ? 0. 368 Therefore, the probability that there are no more than 5 serves in is approximately 0. 368 binomCDF(7, . 82, 5)
