Defense in a Criminal Case Essay Example | Topics and Well Written Essays - 250 words

Defense in a Criminal Case - Essay Example Despite the many perceptions to uphold the insanity mechanisms as a form of defense, defendants hardly enter pleas of being not guilty. After examining the defendant, the psychiatrist produces the testimony to the judge or magistrate who determines the verdict (Mariorty, 2001). However, freedom is not ultimately earned when the judge determine that the accused is not guilty rather a further consideration on the favor of the defendant usually affect the sentence if administered. The defendant is directed to a mental hospital until the allegation of insanity is medically proved, which requires time and may give the convict a chance to escape from the law. Defendant in some instances pretends to be hostile. The main purpose of pretense is to prove to the judge that the defendant is not guilty. In some instances, the defense works when proven by a psychiatrist appointed by the court. As a result, the defendant must ensure that the psychiatrist report is positive about his or her insanity contrary to which the offender faces the full

Pride and Prejudice, Tea in the Wendy House, and He said Essay Example for Free

Pride and Prejudice, Tea in the Wendy House, and He said Essay Pride and Prejudice is a novel of love and marriage and how people have prejudices about love. Pride is involved as it blurs the seeing of true love. Jane Austen displays this as she was part of society and she had first-hand experience of this. In Tea in the Wendy House and He Said, there is an visible change in the role of society and attitudes to love and marriage. This is because of the different times each novel was written. Jane Austen does not make the subject of marriage favourable, as she never writes about a completely happy marriage. For example Mr and Mrs Bennets relationship, this is not an example of a good marriage as Mr Bennet is always taunting Mrs Bennet. Or you may send them by themselves, will be better, for you are as handsome of any of them. Here Mr Bennet is ridiculing Mrs Bennet by saying she should go and visit Mr Darcy as she may end up marrying him, as she is just as beautiful. This was one of Austens intentions to show that the society she lived in was superficial. Another example of a bad marriage is of Charlotte Lucas and Mr Collins. Charlotte is only marrying Mr Collins, as it is her last resort because she is seen as a spinster at the age of 27. Usually girls are married off at young ages, as it is their only ambition. This is shown in Pride and Prejudice, but in Tea in the Wendy House, even though Lyn has an opportunity of marriage she is not happy. She feels pressured into marrying Graham and doesnt have the chance to vent her true feelings properly. She feels she is also trapping Graham into marrying her and becoming a father. I didnt say anything, because Graham was so enthusiastic. She is worried about other peoples feelings and hers but does not get the chance to show them. Whereas in He Said there is no chance of Bev getting married to Errol, as he is too irresponsible. This is an example of the way society has changed drastically. In Pride and Prejudice it was expected for girls to get married straight away and the most important thing in their life. In Tea in the Wendy House there was some expectation but not as much. In He Said society has changed so much that Errol does not think he needs to propose to Bev, even though she is pregnant. This also shows the attitudes to sex before marriage. As Austen shows more bad marriages than good, there were a few happy marriages, as they contain an equality of character traits between the couple. Elizabeth was too prejudiced to realise her true feelings and Mr Darcy was too proud. Even though she does finally realise Darcys good qualities. She began to comprehend that he was exactly the man, in disposition and talents, would suit her. This is the opposite in He Said, as Bev finally realises that she is stronger than Errol, and how she can cope without him. I dont care if I never see him again. In Jane Austens novels the valuable marriage is usually because of chance. If Elizabeth did not read Darcys letter and witness the elopement of Lydia and Wickham, she would have realised how much she values him. This is the opposite in Tea and the Wendy House as Graham and Lyn had known each other since their teens and so had got to know each other better. I was fourteen and Graham was fifteen. As Errol and Bevs relationship in He Said is just based on sex and so there was no previous acknowledgement of character traits. Intervention played its part in the prevention of Darcy and Elizabeth getting married. Elizabeths prejudices intervene and prevent the marriage at first. This does not happen to the main character of Tea in the Wendy House but there is some intervention from Lyns parents. In Pride and Prejudice Elizabeths mum is always pushing her to get the best man she can. She is very bossy and likes to get what she wants. In Tea and the Wendy House it is also Lyns mother that has an intervening nature as she is making the wedding dress. She was busy, giving final touches to the dress. There is a difference in He Said, as her parents do not intervene. Although her father does not want to get involved with her situation, he feels no way in abandoning her when she needs them most. As her father is a minister of a church, he has strict religious beliefs but as he does not want to help he comes across as a bully. If that harlot crosses my doorstep, I will strike her down. Then he had gone to church. This contradicts his religious views. Status is another problem in the prevention of the marriage of Darcy and Elizabeth. Elizabeths astonishment was beyond expression. She stared coloured doubted and was silent. This he considered enough encouragement. Darcy thought that Elizabeth would have said yes when he first proposed, as she may never get a better offer as that one as he is much higher in status than she was. Darcy has a lot more money than the Bennets. In this time it was seen as better if you could marry a man with a large house and very good income. This was so he could provide for his wife when she had children but also to show-off to others. In He Said money is still important to Bev as she is by herself without a husband, so she has to fend for herself. She is struggling and in a poor job. She has not got the financial support from her parents like Lyn in Tea in the Wendy House. Bevs prospects are limited because of lack of money and there is a slight suggestion that this will not change much. There is a sim ilarity between pride and prejudice and Tea in the Wendy House. This is because Lyn and Elizabeth both have some financial support from their parents, although it was not the most important thing in Tea in the Wendy House. Lyns mother puts it across as a bonus to the marriage, but having a good job is quite important. And hes got a job, and course theres the house. You really struck gold there. Mr Collins also demonstrates the status prevention, as he expects her to say yes but it comes across as quite pompous. I am to inherit this estate after the death of your father. He is openly stating that he will own Elizabeths house, as if it was nothing. In the actual proposal of Mr Collins to Elizabeth it was quite formal as he asked permission, which was expected in those times. This differs in the proposal of Graham to Lyn. He seemed embarrassed, it was not very formal but still had the decency to propose. I told you it was corny, but will you, will you marry me? There is no proposal in He Said. Errol obviously does not believe he needs to propose; not formal or gentleman-like. Judgement plays quite a big part of pride and prejudice, as it was a very judgmental society. People are always being judged. Elizabeth prides herself on good understanding of what people are like generally. The extravagance and general profligacy which he scripted exceedingly shocked her. This shows how she was wrong about Mr Wickham and Darcy made her realise this in the letter he wrote to her after he proposed. Good judgement is being to see past deception, pride arrogance and hypocrisy. She tried to recollect some instance of goodness, some distinguished trait of integrity. This shows Elizabeth frantically trying to have some recollection that Mr Wickham was not deceptive and devious. Like Mr Darcy explained in the letter. This is a bad judgement that Elizabeth has made, just like the bad judgement of Errol by Bev. She thought he was going to stand by her throughout the pregnancy, but he does not. I dont want anything to come between usnow he would not speak to her. This shows how shallow and unreliable Errol is. Although she knows Errol is not going to face up to his consequences, it does not stop her from fantasizing about the way she would like things to be between her and Errol. Imagining Errol holding her tightly, perhaps his voice breaking with emotion. Elizabeths first meeting with Mr Wickham compared to her first meeting with Mr Darcy it was not surprised she preferred Mr Wickham. This made her very shocked at the proposal from Mr Darcy. This pitfall almost brings Elizabeth to lose her future husband, although she does come to terms with her mistakes and corrects them. How despicably I have acted, I who have prided myself on my discernment and gratified my vanity, pleased with the preference of one and offended by the neglect of another. This reveals that Elizabeth has recognised her mistakes and how she has treated both men. Darcy has also overcome his arrogance and pride. Austen believes that a happy marriage is built on good judgement and so introduces a genuine perception. So they see each other for who they really are. Tea in the Wendy House, Lyns perception of Graham was not clear, she was not being clear about her feelings. The writer used the Wendy House as symbolism to show that however perfect something seems, it may not make you happy. Although at the end with the last Wendy House reference, you are left wondering if Lyn will ever be happy, but also there is no mention of Graham being with her, in this ideal world. The bright blue walls seem to be closing in around her, the ceiling is coming nearer and nearer. She is a mummy. It doesnt matter that she cant get out. It is making her conform to the stereotypes of typical women. Bev in He Said has made a journey of self-knowledge, from hating Errol for not standing by her to realising she can cope without him, and go along with the pregnancy by herself. From the pressures of society, the doctor telling her it would be best to get an abortion, her father throwing her out, living in a gritty flat and working in a dead end job. Bev has made a miraculous journey from where she was, to feeling confident of having the baby by herself. Elizabeth goes against her time by refusing two marriage proposals, and marrying for true love. In her society a sexual relationship before marriage was seen as unacceptable and shame would be brought onto the family. This is a contrast between our time and Jane Austens time. Lyn is pregnant before she is getting married, this is also the case in He Said apart from Bev is not getting married, and so has to cope on her own. This indicates the age and time Elizabeth lived in. Wickham was this type of person who would deceive women into thinking he loves them but then leaves them. This is what he did with Lydia Bennet. This was not the first he tried; he also tried with Darcys younger sister. He gambles and lives loosely and does not give a second thought to his sexual immoralities. Sex before marriage is seen as the main corrupt. Wickhams character is similar to that of Errol. He does not give a second thought to the consequences of his action. With the faint smell of urine around her realising that probably some man had walked away from relieving himself without a backward thought about the results. Just like Errol. Lydias relationship with Wickham has effected her reputation because of the elopement. Wickhams love for Lydia is not true. This is the opposite with Lyn and Grahams relationship. Graham is truly in love with Lyn, but it is Lyn that has the insecurities and does not feel true love. There is no one in the Wendy house except Lyn. Mandy isnt there. Graham isnt there. This shows how maybe in the end she will be by herself without no one. In Elizabeths time courtship between two people would not have lasted quite long, so Wickham and Lydia were not truly in love, it was most probably infatuation. His belief that Wickham never intended to go there or to marry Lydia at all. Jane Austen was a person in this society and time, which believed marriage, was the most important thing for a young girl. This would lead to prejudices about how much money did the husband have and of what status was he. Jane Austen shows through pride and prejudice that she would not have married because it was convenient but because of love much like Elizabeth. Society has changed, as evident in He said. From wanting marriage as an ambition, to Errol not needing to propose, it does not mean the society has got any better. Society and other peoples thoughts all contribute to prevention of some marriages, even nowadays.

Exploring Schizophrenia Essay -- Psychology Mental Disorders Neurology

Exploring Schizophrenia Schizophrenia which affects approximately 1 percent of the population, usually begins before age 25 and persists throughout life. The illness is a life long debilitating condition for about 40% of patients and is enormously costly in both social and economic terms. Despite the presence of delusions, hallucinations and cognitive impairment which characterize the illness, overall life expectancy is not altered (although there is a significantly increased risk-of suicide in the early years). Schizophrenia is usually viewed as a functional psychosis, a label which implies that the symptoms arise from the disorderly activity of neurons without accompanying anatomical and pathological alterations of brain structure. This view is due to the failure of pathologists to find convincing pathological changes associated with the disease in the first seven decades of the century. Over the last ten years things have changed considerably. Recent CT and MRI scan, and also postmortem studies show that various brain areas of schizophrenic patients are altered. HISTORY The two key people in the history of Schizophrenia were Emil Kraepelin and Eugene Blealer. Kraepelin organized the seriously mentally ill patients by three diagnostic groups: dementia praecox, manic depressive psychosis, and paranoia. Kraeplin?s description of dementia praecox emphasize a chronic deteriorating course, in addition to including such clinical phenomena as hallucinations and delusions. Kraepelin reported that approximately 4% of his patients had complete recoveries and 13% had significant remissions. The term "manic depressive psychosis" identified patients who experienced episodes of illness separated by virtually complete remissio... .... C., Caroff, S.. Dann, R., Silver, F. L., Saykin.

Plant layout Essay

PLANT LAYOUT Outline of Contents: What is Plant layout? Necessity of good layout Factors affecting good layout Principles of good layout Advantages of good layout Symptoms of poor layout Types of layout What is PLANT LAYOUT? Plant layout refers to the arrangement of physical facilities such as machines, equipment, tools, furniture etc. in such a manner so as to have quickest flow of material at the lowest cost and with the least amount of handling in processing the product from the receipt of raw material to the delivery of the final product. Plant Layout is a plan of an optimum arrangement of facilities including personnel, operating equipment, storage space, material handling equipments and all other supporting services along with the design of best structure to contain all these facilities. A good layout is one which allows material rapidly and directly for processing. This reduces transport handling, clerical and other costs down per unit. Space requirement are minimized and it reduces idle machine time and idle time of man. Necessity of good plant layout Minimization of material handling Optimum utilization of available floor space Elimination of bottlenecks through balancing of all capacities Minimization o production delays Easy supervision and better manpower resources through elimination of idle time Elimination of physical efforts required by workers Elimination or improvement of objectionable operations. E.g. Operations with bad odor, vibrating operations etc. Avoiding industrial accidents Better working conditions like light, ventilation, noise control etc. Optimum utilization of machinery and equipment through proper use. Minimization of cost so that product will be available at cheaper rate to customer and  delivery in time. Factors affecting facility Layout Nature of plant-Engineering/Process Industry Type of Production-Mass/Flow, Batch, Job Shop Type of Production-Make to Stock/order, std/spec Plant Location-Area available, building type-storey Volume of Production-Scale of production Types of machines and equipment-automation Repairs and maintenance -Policy, schedule on site Arrangement of material handling equipment Future expansion plan Principles of good Layout Minimum Handling Interdependence Minimum investment Integration of factors-3M Minimum movement-Distance/Flow Continuous flow-forward Optimum utilization of available space Maximum visibility Maximum accessibility Maximum Flexibility Safety, Security and Satisfaction Advantages of Good Plant Layout Proper and efficient utilization of available floor space Transportation of work from one point to another point without any delay Proper utilization of production capacity. Reduce material handling costs Utilize labor efficiently Reduce accidents Provide for volume and product flexibility Provide ease of supervision and control Provide for employee safety and health Allow easy maintenance of machines and plant. Improve productivity Symptoms of Poor Layout Delays and work stoppage in manufacturing process Slow movement of material through the plant Congestion of materials, components and work in progress Poor utilization of space High material handling and transportation costs Excessive handling by skilled workers Production cycles and delays in delivery Mental or physical strain on operators Difficulties in maintain effective supervision and control Underutilization of machines and workers Lack of flexibility and difficulty in production planning and control Types Of Layout: There are mainly four types of plant layout: (a) Product or line layout (b) Process or functional layout (c) Fixed position or location layout (d) Combined or group layout Product or line layout: In this type of layout the machines and equipments are arranged in one line depending upon the sequence of operations required for the product. It is also called as line layout. The material moves to another machine sequentially without any backtracking or deviation i.e. the output of one machine becomes input of the next machine. It requires a very little material handling. It is used for mass production of standardized products. Advantages of Product layout: Low cost of material handling, due to straight and short route and absence of backtracking Smooth and continuous operations Continuous flow of work Lesser inventory and work in progress Optimum use of floor space Simple and effective inspection of work and simplified production control Lower manufacturing cost per unit Disadvantages of Product layout: Higher initial capital investment in special purpose machine (SPM) High overhead charges Breakdown of one machine will disturb the production process. Lesser flexibility of physical resources. Process layout: In this type of layout the machines of a similar type are arranged together at one place. This type of layout is used for batch production. It is preferred when the product is not standardized and the quantity produced is very small. Advantages of Process layout Lower initial capital investment is required. There is high degree of machine utilization, as a machine is not blocked for a single product The overhead costs are relatively low Breakdown of one machine does not disturb the production process. Supervision can be more effective and specialized. Greater flexibility of resources. Disadvantages of Process layout: Material handling costs are high due to backtracking More skilled labour is required resulting in higher cost. Work in progress inventory is high needing greater storage space More frequent inspection is needed which results in costly supervision Combined layout: A combination of process & product layout is known as combined layout. Manufacturing concerns where several products are produced in repeated numbers with no likelihood of continuous production, combined layout is followed Fixed position or location layout: Fixed position layout involves the movement of manpower and machines to the product which remains stationary. The movement of men and machines is advisable as the cost of moving them would be lesser. This type of layout is preferred where the size of the job is bulky and heavy. Example of such type of layout is locomotives, ships, boilers, generators, wagon building, aircraft manufacturing, etc. Advantages of Fixed position layout: The investment on layout is very small.  The layout is flexible as change in job design and operation sequence can be easily incorporated. Adjustments can be made to meet shortage of materials or absence of workers by changing the sequence of operations. Disadvantages of Fixed position layout: As the production period being very long so the capital investment is very high. Very large space is required for storage of material and equipment near the product. As several operations are often carried out simultaneously so there is possibility of confusion and conflicts among different workgroups.

Amy Tan’s ‘Two Kinds’ and Jamaica Kincaid’s ‘Girl’ Essay

A person spends most of their developing years under the guidance of their parents or guardians. They affect how we think, how we feel, and how we act. These are among the people who hold the greatest influence. Amy Tan’s ‘Two Kinds’ and Jamaica Kincaid’s ‘Girl’ both deal with the relationship between a young girl and the guiding force in her life. Amy Tan tells of a mother’s expectation for her daughter to be a child prodigy. Jamaica Kincaid tells of an unknown person describing to a girl how to be a ‘good’ girl. Both essays illustrate an authority figure that has expectations for a young female and why and how those expectations will come about. As young children growing up without a care in the world, we cannot comprehend why authority figures dictate how we should behave. In ‘Two Kinds’, the daughter is expected to be a child prodigy because her mother believes ‘you can be anything you want in Americaà ¢â‚¬â„¢. The mother sees other children with amazing talents and thinks her child could be just as talented, if not more so. She continually places pressure on her daughter to be some kind of prodigy. The daughter is expected to be a great beauty with unmatched dance abilities, an untapped wealth of useless information, and piano-playing skills like no other. In ‘Girl’, the expectations are much lower, but just as stringent. The girl is expected to do a myriad of chores and to become a ‘lady’. She is advised on how she should act and how she can avoid being a ‘slut’. In ‘Two Kinds’, the mother has high hopes; she believes a person can be anything they want in America and she wants a daughter who excels in some area. All of the mother’s hopes lay on the daughter. Her hopes are bolstered by stories about remarkable children with incredible talents. If they can succeed are such a young age, surely her child can as well. The mother wants her daughter to be the best she can be, but she has unrealistic expectations. The girl in Jamaica Kincaid’s essays is not being held to such high hopes and dreams. The expectations placed on her are not as high, but are equally unforgiving. Her authority figure wants her to be the perfect ‘traditional’ girl. She is expected to cook, clean, iron, and not assert her independence. Children, though, are naturally independent and free-willed. For the authority figures to have their way, the girls must be obedient. Obedience and denigration are the methods in which these expectations are supposed to met. In ‘Two Kinds’, the mother states, ‘Only one kind of daughter can live in this house–obedient daughter!’ The daughter does not want to live up to outside expectations, but she does not want to disappoint her mother; part of her feels obligated to be loyal. The mother compares the daughter to other children, which makes the daughter feel worthless. The mother talks about a three-year- old who knows the capital of all the states. She forces the daughter to watch television shows featuring talented youngsters. She implies her daughter is not as good as the other children. In ‘Girl’, the girl is given two choices – be a girl or be a slut. Essentially, she is being told what she must do; there is no room for debate. In between being told what to do, though, the authority figure also reminds her she could well be on her way to becoming a slut. In both essays, the girls come full circle. They both go through a period of being told what to be and what to do. Both girls resent the pressure and expectations put on them in their adolescence, but in the end, they choose paths that lead back to their beginnings. Amy Tan’s girl spends a good portion of her youth hating practicing piano. As an adult, she plays an entire piece of music and is marveled by the beauty of it. In some respects, she becomes the child her mother wanted. Jamaica Kincaid’s girl spends a good portion of her youth protesting the label of ‘slut’ placed upon her. In the conclusion, she becomes the kind of woman she swore she was not.

Profit vs Non Profit Organization Essay Example

Profit vs Non Profit Organization Essay Example Profit vs Non Profit Organization Essay Profit vs Non Profit Organization Essay Essay Topic: Nashville Introduction In healthcare, there are three types of organizations: profit, non-profit and government based organizations. This paper will discuss the differences between profit and non-profit organization and the weaknesses and strengths that each of the organization has. The University of Michigan will be used because it is a prime example of a non-profit organization and its services and the center for spinal surgery hospital will be discussed as a for-profit hospital. Body The University of Michigan’s health system is a non-profit organization located in Ann Arbor, Michigan. It is composed of hospitals, health care centers and clinics. The hospitals and centers that the University of Michigan is comprise of are: medical centers, Mott Children’s Hospital, cardiovascular center, comprehensive medical center, University Hospital, Von Voigtlander Women’s Hospital and the Taubman Center (UofMHealth). The hospital is known to have one of the best performances of heart surgery in the nation for adults and children. The cardiovascular center treats more than 6,000 patients per year that are inpatients and 35,000 patients per year are treated as outpatients. The University of Michigan’s cardiovascular center operates and performs approximately 800 open-heart surgeries on adult and 600 open-heart surgeries on children each year (UofMHealth). Mott Children’s hospital is a teaching hospital that provides many educational programs and research to constantly improve quality care. It is ranked among the best ten hospitals in the United States for its services and quality care. Mott children’s hospital is composed of three intensive care units: the Neonatal Intensive Care Unit, the Pediatric Intensive Care Unit and the Cardiac Intensive Care Unit. Moreover, they have sixteen operating room and two Interventional Radiology Rooms, an Intraoperative MRI OR, 46 Neonatal Intensive Care Unit rooms that are private along with 348 inpatient pediatric beds and 50 maternity rooms. The hospital has blood and marrow transplant suites with onsite pharmacies; pediatric emergency departments are also available with many specialties available to operate when needed. The emergency department has rooftop helipad for patients that are urgently transported from other hospitals. Mott Children is ranked number four for cardiology and heart surgery for pediatric. The Mott children’s hospital Tumor Ecology Program helps and treats children with different kinds of cancer. It is composed of specialized teams in pediatric oncology, pediatric surgery, pediatric radiology and radiation oncology. Their therapies range from surgery to radiation therapy, chemotherapy and stem cell therapy. Many clinical researches and trials are done by using the generated money and surplus to improve quality care and test the most recent technology to give the most promising treatments for their patients (MottChildren). Moreover, the University of Michigan health system has received many awards and was recognized many times and noted to employ the best physicians in the nation. It offers many educational programs and preventive care that is useful for the community. Based on a project that lasted four years, it was noted that the University of Michigan was able to save Medicare $15 million dollars on preventive care through the pay of performance program. Furthermore, their Adult Surgical Intensive Care Unit and the Adult Trauma Burn Intensive Care Unit were recognized and awarded this year for preventing ventilator-associated pneumonia. Clearly, this hospital works hard to improve the community, offer the best and most innovative technologies and offer many educational programs to keep the community healthy (UofMHealth). With all the services, programs and specialties that this healthcare system offers, it is placed within the top non-profit hospitals. Many non-profit hospitals are hindered by not having sufficient specialist care. They tend to offer a wide variety of acute care with the lack of specialization in one particular service. Being a former employee of the University of Michigan, I do not necessarily think that the University of Michigan lack specialty areas; however, I feel that the hospital excels in all specialist services that are being offered to the population. Yet one of the weaknesses that I have noted as being a former employee are the low wages offered. During my previous years of employment, I have noticed that salaries were almost three to four dollars less per hour than any non-profit hospital. In fact, my sister-in-law who is a pediatric cardiologist was offered 30 percent less pay from another teaching non-profit hospital in the area. I believe underpaying employees may lead to a lesser performance and put patients lives at risk. For instance, when 350 suction tips that are used for surgery were investigated at the University of Michigan hospital, it was found that every one of these tips had some kind of contamination by blood, bone, tissue or rust after being sterilized. This is certainly a major concern. Therefore, I believe that workers should be paid fairly to excel in their performance (FoxNews, 2012). On the other hand, the Center for Spinal Surgery is a for-profit hospital that produces income for investors and is not tax exempted. It is a surgical hospital that specializes in spinal care, which is known to provide quality care to their patients the hospital and is located in Nashville Tennessee (HospitalData). (Citation 1) The services that the hospital offers include the following: 1-Lumbar discectomy/laminectomy 2-Anterior cervical discectomy and fusion -Thoracic discectomy/laminectomy 4-Excision spinal cord lesion (CenterForSpinalSurgery). This surgical hospital is composed of 23 beds and physicians operate on 1,273 inpatient and 2,200 outpatients. Also, 93 percent of patients recommend the services of the hospital to a friend and they are satisfied with the care provided to them. The hospital does not contain emergency departments, however it is composed of operating room, outpatient and inpatient facility, pharmacy, postoperative recovery room and radiology. It is noted that the hospital does not have transportation services. However, services will be available if arrangements are made in advance (USNews). As noted, the hospital is highly specialized in spinal surgery and spinal care. It has employed many best-awarded physicians and many patients are satisfied with the services. One suggestion to improve the hospital service would be to offer transportation services to patients to transport them to and from the hospital prior and post-surgery. Another suggestion would be to offer overnight sleep in facility that is adjacent to the hospital for family members because spinal surgeries often take days for recovery. Additionally, it was also noted that the hospital does not offer any community education or research base to improve quality care. This is an important aspect that the population appreciates and takes into consideration. If I were to choose between a profit or a non-profit hospital, I would definitely work for non-profit hospital because their goal is to improve quality care continuously and advance medical care with research and new innovations in order to provide patients with the best treatment available.

This will produce a yield of about 7g or 5.5 cm3, which is 65% of the theoretical yield.EquationC4H9OH + NaBr + H2SO4 = C4H9Br + NaHSO4 + H2OMechanismThe first stage of the reaction the sodium bromide reacts with sulphuric acid and forms hydrogen bromide and sodium hydrogen sulphate:NaBr + H2SO4 = HBr + NaHSO4The hydrogen bromide is then oxidised to bromine molecules due to the fact that concentrated sulphuric acid is a very good oxidising agent. The sulphuric acid reacts to form sulphur dioxide gas:HBr + H2SO4 Br2 + 2SO2 (g)During the next stage of the reaction the hydrogen bromide dissociates and the bromide ion from it attacks the Carbon atom with the -OH function group in Butan-1-ol and displaces the -OH function group forming a bromo function group and a hydroxide ion. This bromo group then associates itself with another H+ ion to form water:CH3CH2CH2CH2OH + Br- CH3CH2CH2CH2Br + OH-In the final stage a molecule of sulphuric acid attacks the lone pair on an -OH function group. This releases a molecule of water, and a mixture of Butoxybutane and But-1-ene is formed, along with the regenerated Sulphuric Acid:CH3CH2CH2CH2OH + H2SO4 CH3CH2CH=CH2 + H2O + H2SO4or2 CH3CH2CH2CH2OH + H2SO4 CH3(CH2)3O(CH2)3CH3 + H2O + H2SO4ResultsMass of NaBr in pot = 11.47gMass of pot = 3.49gMass of Sodium Bromide = 7.98gMass of collecting beaker = 54.25gMass of distillation and beaker = 58.47gMass of 1 bromobutane collected = 4.22gYield ObtainedTheoretical yield = (moles of limiting reagent)(stoichiometric ratio; desired product/limiting reagent)(Mr of desired product)= (0.0941 mole)(1 mole / 1 mole)(137.03g/ mole)= 12.9gActual mass gained = 4.22gTherefore actual yield = (Actual yield / Theoretical yield) x 100= (4.22/12.9) x 100= 32.7%ConclusionFrom my experiment I have found out that the practical yield of 1 bromobutane when made from butan 1 ol, is a lot lower than the theoretical yield, which was stated in a textbook. This difference in yields could be caused by several reasons most of which are down to human error. The first of these human errors could have occurred whilst the liquids were being decanted from one another, at this stage some of the 1 bromobutane may have been left in the beaker and discarded as to keep the amount of impurities in the flask to a minimum. Another human error, which may have caused a lower yield, would be during direct distillation where the temperature may not have been kept between 99 and 103?c. This would have reduced the yield as the chemicals collected would not be pure and therefore the yield would not be as large. A final human error may have occurred whilst waiting for the substance to dry after the anhydrous calcium chloride has been added, this would have caused a reduced yield as again the substance which was final distilled would have been less pure. Therefore the amount of 1 bromobutane boiled off between the frac tions would have been lower than in the theoretical experiment.Another reason that the yield may have been lower other than human error would have been any impurities within the solutions, if these impurities did occur then the boiling temperatures of the substances might have been altered. This would effect the amount of substance that is collected in a fraction temperature range and have an overall effect on the final yield. A final reason the practical yield may have been smaller than the theoretical yield is that the reactants may not have been mixed together at optimum conditions, which would reduce the rate of reaction and therefore reduce the final yield.When running the experiment two changes were made, the first was that instead of using potassium bromide as first planned sodium bromide was used. This is because sodium bromide was easier to get a hold of and was more likely to give a decent yield of 1 bromobutane at the end of the experiment. Another change that was made wa s that at the first distillation, instead of waiting for all the oily drops to fall the only fraction collected was that which boiled of between 99 to 103?c, the boiling point of 1 bromobutane. This increased the accuracy of the experiment as instead of using qualitative information to decide when to stop distilling the liquid we were using quantitative, making the distil more accurate.Overall however the experiment produced a decent yield of bromobutane even though it was not as high as that worked out in the theoretical experiment.EvaluationOverall I feel that the experiment went well as the final yield produced was at least half of the theoretical yield. However there were a few sources of error and these have been highlighted in the conclusion.There are several ways that some of these problems could have been eradicated, and therefore the final yield would have been even greater. One of the easiest problems would have been to use sensors during distillation to record the tempera ture this would mean that fewer impurities would have been boiled off by accident. Also by setting up the experiment so it was easier to change between conical flasks would reduce that amount of distil which was missed during the change over. Another improvement to increase the yield would be to run the experiment at optimum conditions, which would promote a faster rate of reaction due to more collisions occurring and therefore more products being formed and a higher yield being collected.A final improvement to gain a higher yield would be to have allowed the solution to dry for longer this again would cut out some more impurities and therefore increase the yield. This was not done during the actual exam as time was running out and instead of letting the solution settle and then filter out the solid, the solution was allowed to settle and then the clear layers were removed and placed into the pear shaped flask using a pipette.Even though there were some areas in which the experiment could have been improved I feel that the experiment went to a decent degree of accuracy and this is shown by the fact that I got quite a large percent of the theoretical yield in my practical yield.
