Schizophrenia: Reality Distorted Insanity, then, is inordinate or irregular, or impaired action of the mind, of the instincts, sentiments, intellectual, or perceptive powers, depending upon and produced by an organic change in the brain. ---W.A.F. Browne, MD, 18371 Schizophrenia is considered a disease of the brain, a physical disorder that, thanks to modern technology, is able to be visualized. Schizophrenia, along with other diseases of the brain, such as Parkinson's, Alzheimer's, and multiple sclerosis, are all brain diseases which alter both functionality and structure of the brain. Schizophrenia has been called a cruel disease, one that impairs life greatly in a degenerative fashion, altering emotions and various abilities greatly. This unfortunate disease is quite common, effecting about one to two percent of the World's population. About two to four percent of the population suffer from less severe yet still debilitating and disturbing schizophrenic-like symptoms. An estimated sixty five billion a dollars per year is spent on this disorder in the United States.(2) It is estimated that over two million Americans suffer from schizophrenia in their lifetime.. There is a definite biological basis for this disease, although it is not totally understood. For a long time schizophrenia was a mystery to doctors and scientists. Virtually any patient with a psychological disorder used to be placed under the expansive umbrella that defined the disease. Poor parenting was a misleading, early excuse for the troubles caused by what is now known to be substantially based in genetics. The most current idea of origin is that this disorder occurs during the crucial beginning months of life, those spent within the womb. Neither ... ... from it and their friends and family.

Nursing Research Problem Essay

Infections are a common cause of both morbidity and mortality in premature infants; examples of infections include necrotizing enterocolitis (NEC) and sepsis (infection of the bloodstream). Infections in premature infants result in prolonged ventilation, prolonged hospitalization, and higher medical costs, and can cause neurodevelopment impairment (Manzoni et al., 2009). The use of high-potency antibiotics can lead to resistant strains of bacteria and potentially damage the infant’s liver and/or kidney function. Within the past decade, research has turned from finding treatments to finding methods to reduce infections. Breastfeeding and human milk has been well supported through research to provide immunity and positive outcomes for preterm and full-term infants. Breastfeeding and human milk provides nutritional, gastrointestinal, immunological, developmental, and psychological benefits to preterm infants and plays an important role on their long-term health and development (Callen & Pinelli, 2005). The components of breastmilk that support immunity include lactoferrin, lysozymes, interferon, and sIgA antibody (Callen & Pinelli, 2005). Specifically, lactoferrin (LF) is an iron-binding glycoprotein found not only in breastmilk, but also in saliva, tears, and other bodily secretions; LF has biological functions which include immunomodulatory, antimicrobial, and antioxidant effects, and inhibits growth of pathogenic bacteria, fungi, and viruses (Yen et al., 2009). The described functions of LF support the protective role in immunity. The purpose of this investigation is to determine the effects of oral lactoferrin supplementation on reducing infections in preterm infants. Nature of Problem and Importance to Nursing Practice A nosocomial infection is described as an infection that is acquired after 48 hours of hospital admission (Rodriguez et al., 2010). In neonates,  a late-onset infection is defined as an infection obtained after the perinatal period (Manzoni et al., 2009). Nosocomial infections include infections of the gastrointestinal tract (necrotizing enterocolitis, NEC), blood stream (sepsis), and lung (pneumonia). The effects of an infection in a preterm infant can lead to â€Å"poor growth, adverse long-term neurological sequelae, increased length of hospital stay, and a substantial cost to families, hospitals, and society† (Rodriguez et al., 2010, p. 207). The risk of nosocomial infections increases with the decreasing birth weight and gestational age, and roughly 21% of very low birth-weight (VLBW) infants will encounter a late-onset infection (Stoll et al., 2002). The most common gastrointestinal infection in premature infants is NEC, affecting 2.6% to 28% of VLBW infants (Lin et al., 2005). NEC is widely considered as a multifactorial disease, with no specific pathogenesis; three major factors have been proposed: the presence of a pathogenic organism, the challenge of enteral feeding, and altered enteric mucosa integrity (Lin et al., 2005). NEC is â€Å"characterized by necrotizing injury to the intestine that requires antibiotic treatment and, in severe cases, surgical intervention† (Brooks et al., 2006, p. 347). Reduction of infections in preterm infants is of high priority and active research is being performed to find safe preventative measures, improve patient outcomes, and decrease hospital length of stay. Lactoferrin is an iron-binding protein found in mammalian milk and is important in innate immune host defenses (Manzoni et al., 2009). Partial digestion of LF in the stomach produces peptides called â€Å"lactoferricin† that contain more potent antimicrobial activity (Yen et al., 2009). Human colostrum contains more LF than breastmilk, saliva, tears, or other mucosa linings in the body. Studies have been performed to determine bovine or porcine LF effect on prevention of infection in mice and rat pups; conclusions showed a reduction in â€Å"the frequency of bacterial infections in the GI tract while promoting the growth of Lactobacillus and Bifidobacteria species, which are generally believed to be beneficial to the host† (Yen et al., 2009, p. 591). Bovine, porcine, and human LF molecules are similar, and bovine and porcine LF has been reported to show higher antimicrobial activity compared to human LF (King et al., 2007). In 2001, the US Food and Drug Administration declared bovine lactoferrin generally recognized as safe  (CFSAN, 2001). Bovine or human LF can be given as a formula additive, breastmilk additive, or given to patients by swabbing of the mouth, either actively feeding or with nil per os (NPO) statuses. Research studies have now been performed on the effects of bovine or porcine LF on prevention of infections in VLBW and preterm infants, and LF shows to be a promising agent of prevention. Evidence-based Practice Question Evidence-based practice (EBP) is defined as â€Å"a practice that involves clinical decision-making based on the best available evidence, with an emphasis on evidence from disciplined research† (Polit & Beck, 2008, p. 753). Nursing practices are changing in the NICU to include swabbing of the infants mouth with colostrum every six hours to assist in prevention of infection and improve feeding tolerance. The following question is developed to determine the outcomes of infection prevention by LF in preterm infants: Does the supplementation of LF decrease the occurrence of nosocomial infections in preterm infants? Conceptual/Theoretical Framework The studies reviewed did not mention a conceptual or theoretical framework pertaining to the relationship of the subjects investigated. A conceptual model of nursing, Levine’s Conservation Model, can be utilized in applying the methods investigated to provide care and prevention of infection in preterm infants. Levine’s Conservation Model is focused in promoting adaptation and maintaining wholeness using the principles of conservation (â€Å"Current Nursing,† 2010). The model guides the nurse to focus on the influences and responses at the organismic level and accomplish the goals of the model through the conservation of energy, structure, and personal, and social integrity (â€Å"Current Nursing,† 2010). Conservation of energy in preterm infants is necessary for appropriate growth, and is achieved by adequate rest and nutrition; fighting an infection in preterm infants results in NPO status and irritability, thus expending energy. The conservation of structural integrity means to prevent physical breakdown and  promote healing, and is the consequence of an effective immune system (â€Å"Current Nursing,† 2010). The technique of LF supplementation and its potential preventative outcome on infection helps the patient conserve energy and structural integrity. Variables and Findings Manzoni et al. (2009) performed a prospective, multicenter, double-blind, placebo-controlled, randomized trial examining whether oral supplementation with bovine LF alone or in combination with Lactobacillus rhamnosus GG (LGG) reduces late-onset sepsis in 472 VLBW infants. The independent variable of this study is the supplementation of bovine LF or LGG and the dependent variable is the occurrence of infections in VLBW infants. The study randomly allocated infants into three groups; groups consisted of a control group (n = 168, infants supplemented with a placebo) and an experimental group (n = 153, infants given bovine LF alone and n = 151, infants given bovine LF with LGG). The main outcome measured the first episode of late-onset sepsis (sepsis occurring after 72 hours of birth); all tests were two-tailed, and P < .05 was considered statistically significant (Manzoni et al., 2009). When stratifying for birth weight, Manzoni et al. (2009) noted a significant decrease in late-onset sepsis in extremely low birth-weight (ELBW, birth-weight < 1000g) infants (P = .002 for bovine LF v. control and P = .002 for bovine LF plus LGG v. control) whereas it was not significant in infants weighing 1001 to 1500 g (P = .34 for bovine LF v. control and P = .07 in bovine LF plus LGG v. control). Overall, the results showed a significant decrease in the occurrence of infection in VLBW infants in the experimental groups versus the control group (P = .002 for bovine LF v. control and P < .001for bovine LF plus LGG v. control) (Manzoni et al., 2010). A double-blind, placebo-controlled pilot study examined the impact of bovine LF supplementation to bottle-fed infants (King et al., 2006). The participants included 52 infants between the age of 0-4 weeks of age, ≠¥34 weeks of gestational age, and ≠¥2000 g, and who were strictly bottle-fed. The infants were randomized in a double-blind fashion; the control group  received a small dose of bovine LF and the experimental group received a higher dose of bovine LF (King et al., 2006). The independent variable is the supplementation of the higher dose of bovine LF and the dependent variable is the impacts observed in the first year of life. The outcomes measured included diarrhea, upper respiratory infection (URI), acute otitis media (AOM), and lower respiratory tract infection (LRTI). The infants were examined six times throughout the year on the measured outcomes. The results showed a significant decrease in the occurrence of LRTIs in the experimental group than in the control group (P < 0.05) (King et al., 2006). Even though this study did not include preterm infants < 34 weeks, the effects of bovine LF are still apparent in the protection against infection. Yen et al. (2009) performed a study to examine the effects of porcine LF as a selective decontamination of the digestive tract (SDD) regimen in neonatal mice. Transgenic mice were generated to express porcine LF; the neonatal mice fed from the transgenic mice and were then challenged with pathogens to evaluate in vivo antimicrobial activity of porcine LF (Yen et al., 2009). The control group contained mice that were fed normal milk and the experimental group contained mice that were fed the porcine LF (Yen et al., 2009). The independent variable is the transgenic mice with porcine LF supplementation and the dependent variable is the antimicrobial activity observed. The outcome measures included the growth rate of the mice pups, the state of the intestinal tract mucosa, and the circulating cytokines (Yen et al., 2009). Yen et al. (2009) concluded that the experimental group of neonatal mice showed a significant reduction of severity of illness (P < .01), a significant inhibition of microbial survival in the intestinal tract (P < .01), and a significant decrease in the number of bacteria cultured (P < .05) than in the control group. The authors proposed that porcine LF is an ideal natural SDD regimen for the prevention of nosocomial infections in critically ill patients (Yen et al., 2009). Conclusion Research has proven the high incidence of a nosocomial infection and its adverse outcomes in a preterm infant. The efforts of research have changed  to finding a method to reduce or prevent nosocomial infections in preterm infants. Human colostrum is best in supplying the infant with LF to fight infection, but other methods of supplying LF are being studied. Research has recently proven that the supplementation of bovine LF has decreased the occurrence of infections in VLBW and preterm infants. Future research should include a larger, neonatal population specifically targeting VLBW and/or ELBW infants and the effect of LF supplementation on prevention of NEC. Further studies are needed to determine the dosing, duration, and type of LF (bovine, porcine, or human) that will be most effective in the prevention of infection in preterm infants without causing adverse effects or intolerance (Venkatesh & Abrams, 2010).

All The s Men: Theme

The nature of Jack Burden`s journey from the `arid land of facts` to the `dream sea of ideas` is what the story is all about. It goes on to spell whether the journey undertaken by the hero is indeed a spiritual one or an attempt at self-discovery. An attempt has been made to explore the roots of this journey through Modernism (the breakdown of philosophical/moral consensus about the nature of things, the turn toward myth) and Neo-Romanticism (the search for a new unifying principle amid the fragmentations of Modernity/Scientific Materialism), the role of Willie Stark, Ellis Burden, Judge Irwin, and the hero’s journey through the turmoil and pleasures of life. The story revolves around the relationship between the themes of Death and Rebirth which occur in Jack’s journey through incidences of tragedy and beyond. It ends on a note of positivism, when the hero, Jack Burden, transforms himself from being a pawn to his roots in ancestral lineage. Literature Review ‘All the King's Men’, is the story of the rise and fall of Willie Stark, a political titan in the Deep South, who during the 1930s rose from hardscrabble poverty to become the governor of his state, and ultimately it’s most powerful political figure. The story goes on to say how Willie, the anti-hero blackmails and bullies his enemies into submission, and using his good office institutes a radical series of liberal reforms which are designed to tax the rich and ease the burden of the state's poor farmers. This leads to a conflict of personalities which includes the notable former governor, Sam MacMurfee, and other power mongers. Jack Burden, the scion of one of the state's aristocratic dynasties, turns his back on his genteel upbringing, against the wishes of his well-wishers, which includes the influential Judge Irwin. Throwing caution to wind, Jack joins Willie on his journey to stardom, earning him the name as, Willie’s right hand. Willie takes advantage of Jack’s talent as a historical researcher to dig up the unpleasant secrets of his enemies, using this to blackmail and provocation. Cynical and lacking in ambition as he is, Jack walks away from many of his past interests; the dissertation of American History, and marriage to Anne Stanton, the daughter of a former governor of the state. The scene when Willie asks Jack to look for skeletons in the closet of Judge Irwin, Jack is forced to confront his ideas concerning consequence, responsibility, and motivation. He discovers that Judge Irwin had accepted a bribe, and that Governor Stanton, his would-be father-in-law, had covered it up, resulting in Judge Irwin's suicide. The story then turns to another interesting episode of Adam Stanton, Anne’s brother, taking up the directorship of a new hospital being built by Willie. The vicious turn of events leads Willie to Anne, who unsuspectingly has an affair leading to his ultimate murder. Jack, with nothing to gain returns, an empty man. In this we see, the death and rebirth of Jack through his tryst with destiny and forlorn countenance of Anne transform to one of exuberance. Willie's death at the hands of Adam, his loyal employee, jolts Jack to such an extent that he is left dumbfounded and brooding of the consequence of his future and a rethink of his belief. Jack returns to his senses and takes a major plunge towards society by accepting his long lost love, Anne Stanton, and pursues his passion of research . 3. 0 Analysis Jack’s journey from the ‘arid land of facts’ to the ‘dream sea of ideas’ can be best described as a journey towards truth which is emphasized when he says, ‘And all times are one time, and all those dead in the past never lived before our definition gives them life, and out of the shadow their eyes implore us. That is what all of us historical researchers believe. And we love truth. ’ It may be seen that the principal characters in the novel Willie Stark, Judge Irwin, Anne Stanton though their personal lives have not been free from blemishes, they were in more than a way, corrupt. Starting with his association with Willie to the displeasure of his near and dear, the moment he learns of the affair of his first love Anne Stanton with Willie, and to the moment he learns of Judge Irwin’s suicide, Jack had never endured a sign of negativism in Willie’s actions. It is only when Jack’s mother reveals the true identity of his father, does Jack admonishes Willie for his deliberations, although not in public. This incident leads Jack through many a twist and turn in his endeavor to get to the bottom of Willie’s motives. The sequence of events that followed, leading to the untimely murder of Willie, inculcated a sense of disbelief, and revulsion in him. The trudge back to his roots exemplifies the struggle and worship of humanity in all its glory. Jack for all his wiles, was an ardent follower of his master. Willie Stark, ‘the Boss’ gave the impression of a man on the move. Never, did he pause to gauge the consequences of his actions. This ultimately led to his doom. Willie Stark, though he had a humble beginning, rose to a position of wielding unbridled power in the process subjugating his opponents by brute force and of course putting to use the investigative skills of Jack. Judge Irwin, revered as a father figure by Jack, has not been in the good books of Willie, who instigates Jack to dig into the past activities of Irwin, protested vehemently by him. However, when the facts were unearthed, a shocked Jack and a bemused Willie confronted Judge Irwin. Judge Irwin was a man of honor. He was known to be a very straight man and never took the law into his hands. This revelation was too much for him to digest, and equally embarrassing, that he did what a man of his stature would have done, commit suicide. Strangely, for most part of the story, Jack believes that Ellis Burden, whom he refers to as his Scholarly attorney, to be his father, where in fact, it is Judge Irwin who is the real biological father. Ironically, Jack gets to know this only after the suicide of Irwin, which Jack believes was because of his action. Jack’s aristocratic moorings unfortunately does not refrain him from joining hands with the immoral Willie Stark as we see in the story. Though Willie uses Jack as a formidable tool in his ascent to power, using Jack’s research skills to his greatest advantage of subjugating his opponents, was a crime most unsuspecting of such a character. Jack becomes a witness to Willie’s Machiavellian manipulations and misdeeds, albeit, unwittingly. However Jack’s shunning politics at the end of the story and his return to his earlier passion is a metaphor for Jack’s return to his roots, his history, and his American past. In fact, Jack’s research revolves around his study of the life of Cass Mastern, a man of high moral standards and a student at Transylvania College in Kentucky. Even the subject Jack takes up for his dissertation is a reminder to the readers of Jack’s search for the truth. ‘Is death the last sleep? No, it is the last and final awakening,’ said W. Scott, a stark reminder synonymous of the characters in this book; Judge Irwin’s suicide when he is confronted by Jack with facts about his acceptance of a bribe, and the killing of Willie Stark by Adam Stanton. While for the major part of the story Jack believed that the ‘Great Twitch’ denoted actions in life and not words or deeds. The awakening on that morning at home, brought Jack to retract his thoughts on life, and once again believed that men were responsible for their actions and deeds. This rethinking in a sense is responsible for Jack’s decision to marry Anne Stanton (a metaphor for rebirth) despite his knowledge of the fact that he she had an affair with Willie Stark. Reflecting philosophically he says, ‘all the words we speak meant nothing and there was only the pulse in the blood and the twitch of the nerve, like a dead frog's leg in the experiment when the electric current goes through, a true reflection of Modernism. This can be, in a philosophical sense be equated to the death of Jack figuratively, since Anne was Jack’s first love, whom he loved more than anything else in the world. 4. 0 Conclusion In the ultimate analysis it may be inferred that Jack’s life has been a life of journey towards the truth, towards his roots and eventually his self-discovery. The main characters in the story play an important role in molding Jack’s character, the incidents in the lives of those characters enlightening the path Jack has taken to achieve his goal. 5. 0 Bibliography 1. 0 www. sparknotes. com/lit/kingsmen/summary. html

The poem Woman Work Essay Example

The poem Woman Work Essay Example The poem Woman Work Paper The poem Woman Work Paper Essay Topic: Maya Angelou Poems The poem Woman Work is written by Maya Angelou and depicts the daily routine of a black woman in the southern states of America whereas the poem overheard In County Sligo is a poem set in Ireland written by Gillian Clarke. The poem tells the story of an Irish housewife and her unattainable dreams. Woman Work asks us to consider the black womans plea as we hear of the gruelling routine she faces everyday. This woman does not have many wishes; she just strives for a break in her day and dreams of returning to her African home country. We do not know if she has ever been to Africa but she considers it her home. The poem asks us to think about all the things we take for granted as we all have such big aspirations whilst this woman just yearns for a rest. In contrast to this the poem women work tries to make us realise how much women were expected to give up in the early 19th century to become housewives. They were expected to give up their dreams and aspirations and the opportunities of a career for women werent really there. As in woman work the female character in this poem asks us to hear her plea and listen to all her lost dreams and similar to woman work she feels like a slave in her own home. Woman work has five stanzas as does over heard in county Sligo. The first in woman work describes her daily routine and the four after reflect on her dreams and aspirations for life. In comparison to this stanzas in overheard explore the womans situation, dreams and ambiguity, the lady In woman work does not portray ambiguity whereas the lady in county Sligo is said to live in the lap of the land, in the back of beyond. For some people this would be paradise but for her it is like prison; she craves the bustle of a city. The stanzas in woman work are not all the same lengths. The first stanza is long the rest have a pattern of four lines each. The first is longer because it reflects upon her daily routine, long with no breaks, whereas her dreams are put across in the last 4 stanzas and they are smaller and less demanding. This is not the case for overheard; the stanzas are all consistently 4 lines long. Both poems are written in the first person, this really helps us emphasise with the womens feelings and situations. For each poem a lot of dialect and vocabulary are used native to the countries these women are living in, Ireland and Southern America. In over heard it is more the names of places in Ireland which let us know the poem is set there whereas in woman work there is a lot of strong southern American dialect being used. A perfect example of this is the title of the poem woman work. To us this phrase is grammatically incorrect. The poet uses the phrase cane to be cut this is a direct link to slavery and helps us believe she is African. Overheard uses a cyclical effect to great use. The phrase I married a man from county Roscommon is used in the beginning of the first stanza and at the end of the last stanza. It changes its tone when it is used the second time to sound sarcastic on the verge of being cynical whereas in the first stanza it is meant to sound quite idyllic. The first stanza of woman work does not use punctuation neither does overheard. I believe that it is not used purposely in woman work because it reflects upon her hectic schedule in which she has no time for her self. In comparison to this when the woman is talking about her dreams punctuation is used, as if her dreams take her to another place in which she can rest, we also gather this from the repeated use of the word rest. Overheard also uses more punctuation whilst talking about the womans dreams. The main use of imagery is natural or images of nature in both poems. The effect it has on the women though is the complete opposite of each other. In overheard nature is an indication of the prison this woman feels she is in. She hates nature and she strives to get away from it, she is cynical towards nature and the countryside. Its almost as if shes blaming nature or taking her anger out on nature for her failed dreams. This is certainly not the case for woman work. Mature is what comforts this woman and in this poem nature is portrayed as an indication of purity and beauty. Nature is used constantly throughout the last four stanzas whilst she is talking about her dreams and she comments your all I can call my own as if nature is her escape and her only happiness in life, she loves nature in comparison to the hate the woman in overheard feels for it. Woman work contrasts the hectic life she leads and the calmness she strives for whereas overheard contrasts her dreams to her lifestyle.

The Ideas and Inventions Attributed to Archimedes

The Ideas and Inventions Attributed to Archimedes Archimedes was a mathematician and inventor from ancient Greece. Regarded as one of the greatest mathematicians in history, he’s the father of integral calculus and mathematical physics. Here are some of the ideas and inventions that have been attributed to him. While there’s no exact date for his birth and death, he was born approximately between 290 and 280 BC and died sometime between 212 or 211 BC in Syracuse, Sicily. The Archimedes Principle Archimedes wrote in his treatise â€Å"On Floating Bodies† that an object submerged in fluid experiences a buoyant force equal to the weight of the fluid it displaces. The famous anecdote for how he came up with this was started when he was asked to determine if a crown was pure gold or contained some silver. While in the bathtub he arrived at the principle of displacement by weight and ran through the streets naked shouting Eureka (I have found it)! A crown with silver would weigh less than one that was pure gold, Weighing the displaced water would allow calculation of the density of the crown, showing whether or not it was pure gold. The Archimedes Screw The Archimedes screw,  or screw pump, is a machine that can raise water from a lower to higher level. It is useful for irrigation systems, water systems, sewage systems and for pumping water out of a ships bilge. It is a screw-shaped surface inside a pipe and has to be turned, which is often done by attaching it to a windmill or by turning it by hand or oxen. The windmills of Holland are an example of using the Archimedes screw to drain water from low-lying areas. Archimedes may not have discovered this invention since there is some evidence they existed for hundreds of years before his life. He may have observed them in Egypt and later popularized them in Greece. War Machines and Heat Ray Archimedes also designed several claw,  catapult, and trebuchet war machines for use against the armies laying siege to Syracuse. The author Lucian wrote in the second century AD that Archimedes used a heat-focusing device that involved mirrors acting as a parabolic reflector as a way to set invading ships on fire. Several modern-day experimenters have attempted to show this was possible, but have had mixed results. Sadly, he was killed during the siege of Syracuse. Principles of the Lever and Pulleys Archimedes is quoted as saying, Give me a place to stand on and I will move the Earth. He explained the principles of levers in  his treatise â€Å"On the Equilibrium of Planes.† He designed block-and-tackle pulley systems for use in loading and unloading ships.
