Introduction to campylobacter Literature review

Introduction to campylobacter - Literature review Example 163–189). Since campylobacter is present in large quantities in stool, isolation may be considered from this point. However, it is important to note that isolation requires certain conditions of microphilic atmosphere and a media that contains antibiotics. Several methods have been developed to isolate campylobacter. One of them is the membrane filtration. This is used in isolating the microorganism from low turbidity water. Filters of pore size of 0.45 microns are used, and the water is passed as the platting is done face down for the selective agar for the campylobacter. The selective agar is described below in another isolation method. The filters in this process are removed after an overnight incubation. The streaking of plate for isolation before re-incubation then follows this. Prior lab tests have indicated that in the presence of pre-filtration with filters of pore sizes of 6.0 and 5.0 has consistent results of recovery of about 30 jejuni CFU per 250 ml of the seeded water that is nat ural (Line 1711–1715). The other method of isolation is the conventional cultural method. In the laboratory, the sampled specimen is prepared for isolation. If, for example, the sample of raw chicken, a sample of filtrated, chicken rinse water may be used. The water is taken and centrifuged at a rate 16000 times the weight for a period of ten minutes in a minimum temperature of 4 degrees. With an enrichment media of Preston broth, the supernatant is discarded while the pellet is suspended. After the sampled pellet is re-suspended, incubation of the sample at a microbic atmosphere that has 10 percent carbon dioxide, 5 percent oxygen and 85 percent nitrogen. All this happens at a temperature of 3 degrees for 24 hours. The enrichment broth is made consistent with the nutrient broth with supplementation including trimethoprim 10 mg/l, cefoperazone 15 mg/l, rifampicin 5 mg/l, polymyxin B 2500 iu/l and amphotericin 2mg/l. This enriched culture is then placed in

Leadership management assignment 1 Essay Example | Topics and Well Written Essays - 1500 words

Leadership management assignment 1 - Essay Example This is in line with the company’s recruitment policy to help them get the most qualified at affordable remuneration (Luecke 2003). This is therefore done to ensure that the selected individual to fill the position of the manager is the best across the region. They received several applications for the position of the managing director; the group underwent a rigorous recruitment process and finally was left with an individual to negotiate with their starting salary on the job. The remaining individual was from Mexico. In the negotiation process different negotiation skills were outlined that resulted into a successful with a few instances of messing up. Its Human resource manager represented the company on the salary negotiation table while the other side was the individual whose starting salary was to be negotiated (Jacks 2011). Person Position Character A Human resource Manager He is a highly Sociable, Extrovert and democratic B Newly recruited employee Also quite extroverte d, friendly, polite, and highly conscious For new employees of any given firm it is normally safe to negotiate for higher starting salaries before accepting the job offer because after this the new employee will be subjected to the normal salary increase payment plans of the company, which depends on extraordinary performance (Young 1975). The new recruit therefore needed to negotiate for a higher pay than what they used to earn in their former position hence the need for the negotiation skills. The HR manager of company X also needs to be a good negotiator to make sure that they provide the company with manageable expenses and it is willing to negotiate the starting salary of the employee as a whole. The employee is though considering the option of first negotiating the basic pay because given their character they are likely to be confused if they combined the negotiations together with those for the other benefits. This would be to the disadvantage of the employee if the pre-deter mined salary were already advertised (Zartman 1978). A â€Å"Hello Mr. F, this is X company as we talked over the phone, I gaze you are here to talk about the remuneration package of the job offer that we just shortlisted you for the other day. According to the company policy, we would be glad to offer you a salary package of $60,000 yearly plus the benefits, which would vary depending on several variables. Would you be ok with that?† B :I am interested in the job yes but I would not mind if you offered me a salary package of $68,000 per year plus the packages as we would negotiate if it is at the best interests of the company,† A â€Å"$68,000 is not even the average industry rate leave alone what we normally start offering our employees. However, because of your skills and presumed competence, we would not mind offering you a $65,000 package yearly and the benefits as it would be negotiated. How about that?† B "Thank you for your offer and I am certainly intere sted in the position and Company.

COPD Case Study Assignment

COPD Case Study Assignment 1) CASE SUMMARY Mr TLT is a 58 year old taxi driver who was admitted to Hospital Batu Pahat due to newly diagnosed chronic obstructive pulmonary disease. He has had hypertension for the past one year and is taking T Amlodipine 5mg od. He is also a chronic smoker for the past 40 years who smokes about 20 sticks of cigarettes a day. Mr TLT presented with shortness of breath which progressively increased in severity for the past 4 days. The shortness of breath was associated with a wheeze. There was also cough with production of mucoid sputum. The dyspnoea occurred after an episode of upper respiratory tract infection. Mr TLT has been having intermittent chronic cough associtaed with mucoid sputum for the past 3 years. He has also been having persistent breathlessness for the past 1 year especially on exertion. He has not sought treatment prior to this admission. On physical examination, Mr TLT was tacypnoiec with a respiratory rate of 28 breaths per minute. There was no cyanosis. Repiratory system examination showed use of accesory muscles as well as increased anterior posterior diameter of the chest and reduced cricosternal distance. On auscultation, vesicular breathing was heard with generalised rhonchi and coarse early inspiratory crepitations at the lower zone of both lungs. The cardiovascular system examination was normal. There were no other abnormalities on physical examination. Investigations done include chest plain radiograph which showed a hyperinflated chest, tubular heart and absence of vascular markings at the peripheries. The ECG showed sinus rhythm with low voltage. No P pulmonale indicative of right atiral hypertrophy seen. A working diagnosis of acute exacerbation of chronic obstructive airway disease due to upper respiratory tract infection was made. Mr TLT was given nebulization of ipratropium bromide, salbutamol and normal saline for 2 times. His symptoms improved after being given the nebulization. He was discharged after three days when the dyspnoea had resolved. He was given metered dose inhaler of Ipratropium Bromide 40microgrammes tds and MDI salbutamol 200microgrammes PRN. He was given an appointment to assess his symptoms at the outpatient department in one month time. STUDENT NAME: Tan Hai Liang ID NO : M0409146 NAME OF SUPERVISOR : Prof Khin ROTATION: Internal Medicine PATIENTS DETAILS I/C NUMBER : 510912-01-6343 AGE : 58 SEX : Male DATE OF ADMISSION : 2 June 2009 R/N NUMBER : 1143451 2) CLINICAL HISTORY Chief complaint: Mr TLT is a 58 year old taxi driver who presented with shortness of breath for the past four days. History of present illness: Mr TLT is a chronic smoker for the past 40 years who has been smoking about twenty sticks of cigarettes a day. He had been diagnosed with hypertension for the past one year and is currently on T Amlodipine 5 mg od. Mr TLT has been having intermittent chronic cough for the past 3 years. The cough is productive at times. The sputum produced is mucoid in nature and about one tablespoonful in amount. There is no blood in the sputum. It is also not foul-smelling. Mr TLT then proceeded to have shortness of breath for the past one year. The dyspnoea is persistently present and described as requiring increased effort to breathe. It is worse on exertion and Mr TLT experinces reduced effort tolerance. He is now able to climb one and a half flights of stairs before becoming breathless. He has not consulted any doctors for these symptoms prior to admission. Mr TLT then developed symptoms of upper respiratory tract infection such as rhinorrhea and sore throat one week prior to admission. He had fever of 38 degress celcius at that time which resolved with paracetamol. He also had a productive cough with mucoid sputum at this time. Mr TLT then developed increasing shortness of breath 4 days prior to admission. The shortness of breath worsened over the 4 days and was associated with noisy breathing. He was breathless even at rest but was still able to speak in sentences. There was also an increase in cough as well as production of sputum. The sputum was mucoid and non purulent. He also did not notice any blueness around his lips or at his fingers. Systemic review: There was no loss of appetite or loss of weight. He had mild ankle oedema but no other signs of heart failure such as orthopnoea or paroxysmal nocturnal dyspnoea. Past medical history Mr TLT has not had any hospital admissions prior to this. He was diagnosed with hypertension last year as an incidental finding during a visit to the kilinik kesihatan for an upper respiratory tract infection. He is currently taking tablet Amlodipine 5 mg once daily. Family history Mr TLT is the eldest of 5 siblings. There is a strong family history of hypertension in that his mother as well as two other siblings are also hypertensive. There is no family history of asthma, diabetes or ischaemic heart disease. Social history Mr TLT used to work as a taxi driver but has stopped working full time 2 years ago. He still occasionally drives his taxi but spends more time at home with his family. He is a chronic smoker for the past 40 years and smokes about 20 sticks of cigarrettes a day. He drinks alcohol with his friends on weekends. He drinks one to two bottles of beer each time. STUDENT NAME: Tan Hai Liang ID NO: M0409146 NAME OF SUPERVISOR: Prof Khin ROTATION: Internal Medicine ____________________________________________________________________________ 3) FINDINGS ON CLINICAL EXAMINATION On general examination, Mr TLT was well nourished and alert but was tachypnoiec. He was able to speak in sentences but there was use of his accessory muscles. There was no clubbing or cyanosis seen. There was also no peripheral oedema, pallor or jaundice. Vital signs: Pulse rate: 72 beats per minute, regular with good volume. No bounding pulse. Respiratory rate: 28 breaths per minute Blood pressure: 129/73 Temperature: 37 degrees Celsius SpO2: 95% under nasal prong oxygen 3 litres per minute Examination of the respiratory system: On inspection of the hands, there was no peripheral cyanosis or flapping tremors seen. There was also no clubbing, muscle wasting or palmar erythema seen. There was presence of nicotine stains. The jugular venous pressure is mildly elevated at 3.5 cm above the sternal angle. On palpation of the trachea, the trachea is central but the cricosternal distance is 2 fingers which is reduced. The apex beat could not be palpated. On inspection of the chest, there is an increased anterior posterior diameter giving rise to a barrel shaped chest. The chest moves equally with respiration and there is use of accessory mucles with intercostal, subcostal and suprasternal retraction. There are no chest wall deformities. On palpation, chest expansion is reduced on both sides. Tactile fremitus is equal on both sides. On percussion, there is hyperresonance over both lungs with loss of liver and cardiac dullness. On auscultation vesicular breathing is heard. There is generalised expiratory rhonchi. There is also fine early inspiratory crepitations heard at the lower zones of both lungs. Examination of the cardiovascular system: The apex beat could not be palpated. There were no parasternal heaves or thrills palpable. On auscultation, normal first and second heart sounds were heard. There was mild bilateral pitting oedema. Examination of the abdomen: On inspection, the abdomen is flat and moves with respiration. There was no guarding or tenderness. The liver and spleen were not palpable. There was no organomegaly. Examination of the neurological system was normal. STUDENT NAME: Tan Hai Liang ID NO: M0409146 NAME OF SUPERVISOR: Prof Khin ROTATION: Internal Medicine 4) PROVISIONAL AND DIFFERENTIAL DIAGNOSES WITH REASONING Provisional diagnosis: Acute exacerbation of newly diagnosed chronic obstructive airway disease due to upper respiratory tract infection. Evidence for: Patients with chronic obstructive airway disease (COPD) usually present with a persistent dyspnoea and reduced effort tolerance which was present in the history given by Mr TLT. He is also at increased risk of developing COPD due to exposure to associated risk factors such as tobacco smoke. He has been a chronic smoker for the past 40 years. There is also the presence of chronic cough occasionally associated with mucoid sputum which further suggests COPD. Physical findings of a hyperinflated chest and vesicular breathing with generalised expiratory rhonchi also point to an obstructive airway disease. During this admission Mr TLT had increasing severity of shortness of breath even at rest. This was associated with a wheeze that was described as noisy breathing. Sudden worsening of symptoms suggest an episode of acute exacerbation. The history of upper respiratory tract infection symptoms suggest that it was the trigger for this episode of exacerbation. Differential diagnosis: 1) Congestive cardiac failure. Mr TLT may have developed congestive cardiac failure as a primary event or as a complication of chronic lung disease. There is history of reduced effort tolerance. Patients with congestive cardiac failure may also present with a wheeze and sudden increase in dyspnoea. Physical examination of fine crepitations at both bases of the lungs may also indicate congestive cardiac failure. There is also evidence of mildly raised JVP as well as mild pittint ankle oedema. Evidence against: There is no history of any cause of heart failure such as ischaemic heart disease or cardiac valve defect. Mr TLTs previous records during follow-up show well controlled blood pressure. Additional investigations need to be carried out in order to rule out this condition. A chest plain radiograph may be done in order to look for evidence of heart failure such as cardiomegaly. An ECG may be done to look for right atrial hypertrophy. An echocardiogram should also be performed in order to assess the function of the ventricles. 2) Bronchiectasis Patients with bronchiectasis have a history of chronic cough as well as production of copious amounts of sputum. They may also have persistent shortness of breath, reduced effort tolerance and wheeze. Evidence against: The sputum produced by Mr TLT is mucoid in nature and not purulent which is typical in bronchiectasis. It is also not copious and foul smelling in nature. On physical examination, coarse crepitations would be heard in bronchiectasis as opposed to the fine crepitations heard in Mr TLT. There is also no evidence of clubbing. Chest plain radiograph should be done in order to look for thickened bronchial walls or cystic shadows. STUDENT NAME: Tan Hai Liang ID NO: M0409146 NAME OF SUPERVISOR: Prof Khin ROTATION: Internal Medicine 5) IDENTIFY AND PRIORITISE THE PROBLEMS 1. Shortness of breath and reduced effort tolerance Mr TLTs chief complaint is shortness of breath. This may be attributed to the increase in number of goblet cells and later on fibrosis of the bronchial walls causing airway obstruction seen in chronic obstructive airway disease. The shortness of breath may be partially relieved with the use of nebulization of ipratropium bromide, salbutamol and normal saline or with the use of metered dose inhalers. Chest physiotherapy may also be useful. Mr TLT also has had reduced effort tolerance and persistent dyspnoea for the past a year. As such he may require the use of ipratropium bromide in a metered dose inhaler upon discharge in order to feel less breathless due to the bronchodilator effect of the ipratropium bromide. 2. Upper respiratory tract infection Mr TLT may require antibiotics as he still has symptoms of upper respiratory tract infection such as sore throat. Furthermore patients who present with an acute exacerbation are at greater risk of having a bacterial infection. This is because of the depressed immune state that the patient is in as a result of the acute illness as well as due to any steroids that would be given as part of the management plan. The appropriateness of usage of antibiotics in chronic obstructive airway disease will be further discussed below. 3. Adequate inhaler technique Mr TLT would need to be taught about the correct technique to be used when using metered dose inhalers. He would probably require daily use of ipratropium bromide metered dose inhalers to reduce his breathlessness. In the event that he is unable to learn proper technique, he may be encouraged to buy an aerochamber. 4. Smoking cessation Mr TLT should be counseled on smoking cessation as it has been proven that smoking cessation would alter the course of progression in COPD and is associated with lower all-cause mortality. He should be counseled on the various options of smoking cessation which will be discussed further below. STUDENT NAME: Tan Hai Liang ID NO: M0409146 NAME OF SUPERVISOR: Prof Khin ROTATION: Internal Medicine 6) PLAN OF INVESTIGATION, JUSTIFICATIONS FOR THE SELECTION OF TESTS OR PROCEDURES, AND INTERPRETATION OF RESULTS 1) Full Blood Count Justification: In order to view the total white count as well as the differential count to see if there is an infection which has caused this episode of exacerbation. There may also be secondary polycythemia if the patient has chronic pulmonary hypertension. Results: White cell count : 7.91 X 109/L Red blood cell : 4.48 X 1012/L Haemoglobin : 133.00 g/dl Haematocrit : 42.00 ratio Mean cell volume : 93.80 fL Mean cell haemoglobin : 29.70 pg Mean cell haemoglobin conc. : 317.00 g/l Platelets : 141.00 X 109/L Differential count Neutrophils : 60.10% 4.76 X 109/L Lymphocytes : 25.30% 2.00 X 109/L Monocytes : 13.80% 1.09 X 109/L Eosinophils : 0.50% 0.04 X 109/L Basophils : 0.30% 0.02 X 109/L Interpretation: This is a normal full blood count result with normal total white count as well as normal haemoglobin levels. 2) Plain chest radiograph Justification: Done in order to look for evidence of chronic obstructive airway disease such as hyperinflated chest or evidence of congestive cardiac failure such as cardiomegaly and prominent upper lobe vessels. Results: Hyperinflation of the chest with the 7th anterior rib crossing the diaphragm. No other abnormalities seen. Interpretation: Hyperinflation of the lung fields is consistent with the provisional diagnosis of chronic obstructive airway disease. 3) Sputum FEME, culture and sensitivity (not done) Justification: In order to look for any bacteria which may have been the cause of the exacerbation . If there any organism cultured, proper antibiotics can be given based on the sensitivity test. 4) Arterial blood gas (not done) Justification: May be necessary in severe cases of breathlessness to look for respiratory failure and associated changes in blood pH. 5) Blood urea serum electrolytes and creatinine Justification: To look for renal impairment which may be present due to Mr TLT having hypertension. Renal impairment may also affect the dosage and type of antibiotics used. Results: Urea : 3.7mmol/L Sodium : 135 mmol/L Potassium : 3.7 mmol/L Creatinine : 65 umol/L Interpretation: Normal result. There is no renal impairment 6) Electrocardiogram Justification: To look for evidence of right ventricular hypertrophy or right atrial hypertrophy which may be seen in chronic lung disease. Results: ECG with sinus rhythm. There is no P pulmonale seen. There is low voltage seen. No ischaemic changes seen. No left ventricular hypertrophy. Interpretation: Normal ECG with low voltage is seen in a hyperinflated chest such as in patients with COPD STUDENT NAME: Tan Hai Liang ID NO: M0409146 NAME OF SUPERVISOR: Prof Khin ROTATION: Internal Medicine 7) WORKING DIAGNOSIS AND PLAN OF MANAGEMENT ON ADMISSION Working diagnosis: Acute exacerbation of chronic obstructive airway disease due to upper respiratory tract infection My proposed plan of management is as follows: Acute management 1. Provide supplemental oxygen via nasal prong 3L/min and maintain SpO2 above 90%. Arterial blood gas should be done in order to ensure adequate oxygenation without carbon dioxide retention of acidosis. 2. Close monitoring of vital signs and SpO2 hourly until the patients breathlessness improves. Nursing staff to inform if patient deteriorates such as increased respiratory rate or drop in oxygen saturation below 92%. 3. Give nebulization of Ipratropium Bromide:Salbutamol:Normal Saline in ratio of 2:2:1 every four hours until breathlessness decreases. 4. Oral prednisolone 40mg once daily for 10 days 5. Postural drainage and chest physiotherapy may be performed. 6. Oral antibiotics such as T. Cefuroxime may be given. This was not given in this patient with further discussion below. Long term management 1. MDI ipratropium bromide 40 microgrammes tds 2. MDI salbutamol 200 microgrammes PRN 3. Counseling on proper inhaler technique. 4. Couseling on smoking cessation. STUDENT NAME: Tan Hai Liang ID NO: M0409146 NAME OF SUPERVISOR: Prof Khin ROTATION: Internal Medicine 8) SUMMARY OF INPATIENT PROGRESS (INCLUDING MAJOR EVENTS, CHANGE OF DIAGNOSIS OR MANAGEMENT AND OUTCOMES) Mr TLT was warded for a total of 3 days. His breathlessness improved after nebulization with ipratropium bromide, salbutamol and normal saline for one day. He no longer required nebulization after one day. Mr TLT was also able to ambulate without feeling breathless. He was able to eat and to sleep well without being bothered by the dyspnoea. His vital signs were also normal and his respiratory rate improved to about 20 breaths per minute. There was still some ronchi heard on auscultation but it was much reduced. He was afebrile during his stay. Mr TLT was discharged after 3 days of admission and educated on chronic obstructive airway disease. He was also counseled on the importance of smoking cessation. He was given an appointment with the medical outpatient department in one month time in order to review his symptoms after being given MDI ipratropium bromide. He was told to return to the hospital if he had similar episodes. STUDENT NAME: Tan Hai Liang ID NO: M0409146 NAME OF SUPERVISOR: Prof Khin ROTATION: Internal Medicine 9) DISCHARGE PLAN, COUNSELLING AND MOCK PRESCRIPTION Discharge Plan 1. Medications: i. MDI Salbutamol 200 µg PRN ii. MDI Ipratropium Bromide 40 µg TDS iii. T. Amlodipine 5mg once daily iv. T. Prednisolone 20mg od for 7 days. 2. Counseling on COPD and use of metered dose inhaler Mr TLT should be taught about the correct technique in using a metered dose inhaler. The technique should then be assessed before discharge. In the event that Mr TLT is unable to coordinate well, he may be advised to purchase an aerochamber. 3. Counseling on smoking cessation The approach to counseling a patient on smoking cessation as well as various options will be further discussed below. 4. Education on the symptoms of an acute exacerbation and advise to return to the hospital if there is development of those symptoms. 5. For follow-up at the medical outpatient department for review of symptoms while on MDI ipratropium bromide. He should also be taught about pulmonary rehabilitation. A spirometry appointment may also be made. STUDENT NAME: Tan Hai Liang ID NO: M0409146 NAME OF SUPERVISOR: Prof Khin ROTATION: Internal Medicine 10) REFERRAL LETTER (MANDATORY) Dr Tan Hai Liang Medical Department, Hospital Batu Pahat Family physician, Klinik Kesihatan Batu Pahat, 83000 Batu Pahat, 10 June 2009 Dear esteemed colleague, Patients name: Teo Lai Thing Patients I/c number: 510912-01-6343 Problem: Chronic Obstructive Airway disease Thank you for seeing this 58 year old gentleman who is hypertensive for the past 1 year currently on T. Amlodipine 5mg once daily. He presented to Hospital Batu Pahat with shortness of breath for 4 days that was increasing in severity. A diagnosis of chronic obstructive airway disease was made. He was discharged uneventfully on the third day of admission with the following medication: MDI Salbutamol 200 µg PRN, MDI Ipratropium Bromide 40 µg TDS and T. Amlodipine 5mg once daily. Mr Teo has been a chronic smoker for the past 40 years and smokes up to 20 sticks of cigarettes a day. We have counselled him about the benefits of smoking cessation while in the ward. He is currently considering it and would like to learn more about the various options of smoking cessation. Kindly assess the patients keenness for smoking cessation as well as provide him with additional information on the options available to quit smoking. Thank you. Sincerely ____________ (Tan Hai Liang) Medical Department Hospital Batu Pahat STUDENT NAME: Tan Hai Liang ID NO: M0409146 NAME OF SUPERVISOR: Prof Khin ROTATION: Internal Medicine 11) LEARNING ISSUES IN THE 8 IMU OUTCOMES 1) Communication skills What are the benefits of smoking cessation in COPD patients and how should counseling be done? Counseling for smoking cessation should play a significant role in the holistic management of a patient with chronic obstructive airway disease. This is because studies have shown that smoking cessation changes the clinical course of COPD by preserving lung function. One study of patients reviewed at 14.5 years after stopping smoking showed that smoking cessation intervention showed 18% reduction in all-cause mortality compared with usual care without smoking cessation intervention. Patients who had stopped smoking had lower rates of death due of coronary heart disease , cerebrovascular disease, lung cancer, and other respiratory disease as compared with those assigned to usual care who continue to smoke. [1] Fig. 4. Effect of smoking cessation on mortality cause at 14.5 years in the Lung Health Study. (A) Comparison of smoking cessation intervention with usual care. (B) Comparison according to smoking status. I therefore looked up for counseling methods for smoking cessation. The American College of Chest Physicians recommend that physicians should be the first line in introducing smoking cessation. [2] There are 5 As that a doctor should perform for a patient who is a smoker: †¢ Ask about tobacco use at every visit †¢ Advise tobacco users to quit †¢ Assess the willingness to attempt quitting †¢ Assist the patient with methods for quitting †¢ Arrange for follow-up contact via phone or face to face If the patient is not yet willing to quit, there are 5 Rs which should be identified together by the patient and the doctor: †¢ Relevance of quitting for the patient †¢ Risks of illness related to continued tobacco use †¢ Rewerds/benefits of smoking cessation †¢ Roadblocks for quitting, internal and external †¢ Repetition of the motivation intervention at each encounter There are two means of intervention in smoking cessation namely pharmacological and behavioural. The pharmacological means include nicotine replacement therapy or buproprion. Behavioural interventions include counseling programs that teach problem-solving skills and support groups. [3] In conclusion, I learned that doctors have an important role in actively encouraging patients who smoke to stop as there are many proven benefits of smoking cessation. The steps discussed above on techniques in the counseling of patients would be helpful to me in the future. 2) Professionalism, ethics and personal development Should antibiotics be given for episodes of exacerbation of chronic obstructive airway disease? Mr TLT was not given antibiotics during this episode of exacerbation. Certain quarters support the use of prophylactic antibiotics in all exacerbations due to the knowledge that most exacerbations are caused by the common organisms of Streptococcus pneumoniae (S. pneumoniae), Haemophilus influenzae (H. influenzae), Pseudomonas aeruginosa (P. aeruginosa) and Moraxella catarrhalis (M. catarrhalis). Sputum culture may not be useful as even in the clinical stable state, some patients have sputum positive for bacteria. As such a broad spectrum antibiotic is usually used to cover different bacteria. However, is this use of antibiotics justified in that do patients benefit from it or is the overjudicious use of antibiotics merely promoting antibiotic resistant bacteria? Current Global initiative for chronic Lung Disease guidelines [4] recommend that antibiotics should be given in: i) patients with exacerbations of COPD and the three cardinal symptoms of increased dyspnoea, increased sputum volume and increased sputum purulence. ii) patients with exacerbation of COPD with two of the cardinal symptoms if increased purulence of sputum is one of the two symptoms iii) patients with severe exacerbations of COPD that requires mechanical ventilation A meta-analysis by Ram et al [5] of 11 placebo controlled RCTs with 917 patients attempted to analyse the value of antibiotics in the management of acute COPD exacerbations. The results show that there is a decrease in short-term mortality, treatment failure and sputum purulence with antibiotic therapy compared to placebo. The authors concluded that antibiotics therapy is appropriate in exacerbations of COPD associated with increased cough and sputum purulence. They further found that antibiotics have the greatest effect for patients with severe exacerbations who are admitted to the hospital. They were unable to comment on exacerbations with non-purulent sputum, what antibiotics were the best to be used and also the duration of therapy due to the lack of RCTs done on these aspects. In conclusion, it was appropriate that Mr TLT was not given antibiotics as he did not have the cardinal signs as mentioned by the GOLD guidelines and further supported by the systemic review. 3) Self directed life long learning What are extrapulmonary manifestations of COPD and what are its therapeutic implications? Chronic obstructive lung disease has long been known as a localized pulmonary disorder. However new evidence have shown that COPD may be a systemic disease that involves pathology in several extra-pulmonary systems. An article by Remels et al [6] summarized the extrapulmonary manifestations as well as its implications on the holistic management of chronic obstructive airway disease. The article showed that there is skeletal muscle dysfunction as well as systemic inflammation in chronic obstructive airway disease. There is loss of muscle mass associated with impaired protein metabolism. The loss of muscle mass which is called sarcopenia may progress to cachexia. Studies have also shown that there is increased apoptosis of muscle cells at the cellular level. Independent of the loss of muscle mass is the reduced muscle endurance. This finding has been attributed to abnormalities in mitochondria or to hypoxia. These findings have significant implications on management of a COPD patient which will be discussed below. Systemic inflammation is also seen in patients with COPD. This is evidenced by elevated levels of the proinflammatory cytokines such as tumor necrosis factor-alpha (TNF-a), interleukin-6, interleukin-8, and TNF-a receptors. The origin of the systemic inflammation is thought to be independent of the pulmonary manifestation of COPD. One postulation is the increase systemic inflammatory mediators such as neutrophils and lymphocytes in the circulation of patients with COPD. Another proposed mechanism is increased cytokine production due to chronic hypoxia. The therapeutic implications of these findings is that muscle atrophy should be prevented by resistance exercise as well as combined strength and endurance exercise. Current Malaysian guidelines on the management of COPD [7] recommend pulmonary resistance including lower and upper limb exercises as well as inspiratory muscle training. This concurs with a Cochrane metaanalysis by Lacasse et al [8] which strongly support respiratory at least four weeks of exercise training as part of the of management for patients with COPD. The authors found that there was clinically and statistically significant improvements in quality of life as measured by dyspnea, fatigue and emotional function. 4. Critical thinking and research What is the efficacy of systemic corticosteroids for acute exacerbations of chronic obstructive airway disese? The use of systemic oral or intravenous corticosteroids is recommended by GOLD guidelines in the management of acute exacerbations of chronic obstructive airway disease. However the patient, Mr TLT was not given any systemic corticosteroids. This could be because he merely had a mild exacerbation. I therefore looked up a Cochrane metaanalysis on the use of systemic corticosteroids for acute exacerbations of chronic obstructive airway disease [9]. The authors reviewed randomized controlled trials comparing parenteral or oral corticosteroids with placebo for the treatment of exacerbation of COPD. The primary outcomes measured were treatment failure (hospital readmission, return to emergency department), relapse and mortality. The authors reviewed 11 studies involving 1081 participants. The results show a statistically significant difference between placebo and use of corticosteoids. There was less treatment failure in patients given corticosteroids. Relapse within 30 days were also reduced. However there was no statistically significant reduction in mortality. As such the authors concluded that administration of oral or parenteral corticosteroids in the treatment of acute exacerbations of COPD reduces the likelihood of treatment failure. This is associated with early and continuing improvement during treatment with corticosteroids in lung function, breathlessness and blood gases and with a shorter hospital stay. This in turn has a positve impact on the economic cost of treating exacerbations, with fewer follow-up visits and hospital admissions. The authors also found that although there is an increased incidence of corticosteroid side effects such as fluid retention, hypertension and adrenal suppression, the effects are unlikely to persist after treatment ceases.

The United States should drill for oil in the ANWR - Alaskan National Wildlife Reserve :: essays research papers

Proposition: The United States should drill for oil in the ANWR. Significance: Right now, The United States of America languishes in an economic decline. Jobs are being lost. Drilling in the ANWR will create hundreds of thousands of jobs. Also, 80% of Alaska’s state revenues are oil. With the North Slope oil fields in decline, Alaskans could lose jobs. Drilling in the ANWR will create jobs for Alaskans. As Jennie Wodkowski, who has lived in Alaska for 34 years said, â€Å"Oil’s important. We don’t have anything else going on here.† Rationale: 1. Harms the Environment 2. Costs Billions 3. Nobody willing to Drill 4. Not much Oil 5. Won’t create jobs 6. Not worth the time My opponents 1st/2nd/3rd contention was the drilling in the ANWR will harm the environment. This is absolutely incorrect. Lets put this into perspective, the ANWR is 19.6 million acres out of Alaska, which is 240 million acres. The proposed drilling in the coastal plain will be 1.5 million acres. Now, with the new technology we have today, we can tap into the 1.5 million acre oil supply with an oil area that is 2000 acres. 2000 acres is 1/10000 or .0001% of the ANWR. 1.5 million acres of oil and a minuscule possibility of harming at max, 1/10000, I repeat 1/10000th if the ANWR. (Arctic Power) Also, drilling in Alaska will not harm the wildlife. Take Prudhoe Bay for example. The Central Arctic Caribou Herd that occupies Prudhoe Bay has grown from a population of 6000 in 1978 to 27000 today. This is a 450% growth over 26 years at an average of 17.3% growth per year. (Arctic Power) That’s quite an increase. Furthermore, the ANWR is not a pristine wilderness with magnificent wilderness and beautiful wildlife at every corner. That is a illusion generated by anti – drilling supporters. The truth is that in the wintertime, the ANWR is 60 degrees below and 99 degrees below if you count the wind-chill factor. As Senator Ted Stevens of Alaska said â€Å"It (the ANWR) is hell in the wintertime. This is not some pristine place that should be protected.† Drilling will not harm wildlife or the environment. My opponents 1st/2nd/3rd contention was that drilling in Alaska will cost billions. True, drilling in Alaska will cost billions but the positive impact on the U.S. economy far outweighs the cost. Also, the billions of dollars it will cost to drill in the ANWR will be mostly paid by companies who want to develop into the ANWR, not the U.

One word that has changed the world

Do you love apples? Well, Ido love apples! However, it is not because it's nutritious, instead, it haschanged world. Why? You may ask, or you may come to realize that Job's productsof apple brand have indeed brought us dramatic changes. You're partially right! Actually, in the longprocess of history, there are three apples that have exerted significant impacton us. One was bitten by Eva, one fell on Newton's head, and another on is inthe hand of Steven Jobs. The three great apples have shaped a brand-new worldwith a fire-new outlook.The three great apples have signified a usion of curiosity,intelligence, innovation and technology. The three great apples have endowed uswith a window to look through an unknown world, to explore, to innovate, toprogress and to advance. Eva's apple is a metaphor of human's curiosity. Curiosity is a child-like sense of wonder, making usquestion things that others do not even notice. Einstein once put it â€Å"I'mneither especially clever nor especially g ifted, I'm only very, very curious. † Hewent on to say that, â€Å"the important thing is not to stop questioning. Withthis regard, he proposed the relativity theory, a milestone in hysics, aleapfrog of human development. Stories like this happen all the time. Becauseof curiosity, we have been eager to explore the outer space, is there anyliving creature in outer space, is there any possibility to live on otherplanets so that helping release huge burden of congestion, climate variationand other knotty issues. Curiosity drives us to the Journey of exploration ofthis mysterious and unfathomable world. Curiosity propels us to fgure out allthe truths and facts.Newton's apple is amanifestation of human's intelligence. We can speak, we can create, we can makea ifference. All these features have distinguished us as a unique creature, Justa saying goes† there's nothing as precious as humans in the world†. Thanks tointelligence, our ancient ancestors have created a brillia nt civilization thatinspired the world for centuries. Due to their intelligence and endeavor, wehave transferred from a primitive society to a modern one. Intelligence is thesource of our development. Apple intelligence leads us to advance. Jobs' apple is a symbol of dailyupgrading technology.In retrospect, we'll fgure out that we have been livingin a orld tightly connected with technology, particularly, after the 1990s. Becauseof technology, our life now is strikingly different. With TV, we are immersedin extensive entertainment and relaxation, with telephones, we are delighted inconvenient and efficient contact with families and friends, with MP3, we areenchanted in melodic music at anytime anywhere, with internet, we are involvedin a wide range of activities—chatting online, sending mails, shopping,getting information and so forth. Every day, we're marveled at fabulous giftsfavored by technology.Apple technology akes us to innovation andtransformation. Whether you're holdi ng anipod 4 or you're holding 4 packs of apples. World is waiting for us to make a differenceand the three great apples have spured the most unparalleled and tremendouschanges for the world. The great apples, namely, curiosity, intelligence andtechnology are the source of strength of enterprising, pioneering andprogressing. Apple, is more than anapple. It is a word that has changed the world and it's my solid convictionthat another apple is to change the world! One word that has changed the world By gluttonysJt

Lab Report Conclusion

Conclusion In this experiment, we measured the mass of 4 gasses; oxygen, carbon dioxide, helium, and lab gas. We took a Ziplock bag, and turned into a non-stretchy balloon, and filled with each gas and measured the apparent mass then calculated the actual mass, then find a ratio between the mass of oxygen and the other gasses. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide, and the lightest was helium.In fact, helium and lab gas had a density below 0. Anyways, it turned out that our apparent masses were very different from our actual mass calculations; for example oxygen’s apparent mass was 28. 33g but its actual mass was 4. 10g. We also found the ratios, and after collecting class data, our carbon dioxide ratio was 1. 39/1g, our helium ratio was . 21/1g, and our lab gas ratio was . 59/1g. Then we had to come up with two hypotheses to figure out why one gas is heavier (denser) than another?Well, we came up with hypothesis #1: The different molecule mass hypothesis, and hypothesis #2: The more molecules in the same volume hypothesis. After having a class discussion, turns out that hypothesis one is more reliable due to Avogadro’s hypothesis; if two gasses at the same temperature and equal volume contain equal amount of molecules. So according to the statement above, the carbon dioxide molecules must be 1. 39x bigger than an oxygen molecule, a helium molecule must be . 21x bigger, and . 59x bigger than an oxygen molecule.

Tartuffe by Jean-Baptiste Poquelin Moliere Essay Example

Tartuffe by Jean Tartuffe by Jean-Baptiste Poquelin Moliere Paper Tartuffe by Jean-Baptiste Poquelin Moliere Paper Essay Topic: Literature Tartuffe, a play by Jean-Baptiste Poquelin Moliere, is a poignant story about a man, Orgon, who is totally and completely taken in and blinded by a scoundrel named Tartuffe. Orgon has utter faith and shows unconditional love for this poor pious man, Tartuffe. Orgon is willing to sacrifice everything his wife, his family, his daughters happiness and even his large estate. Orgon believes that under Tratuffes tutelage my souls been freed from earthly loves, and every human tie:/ My mother, children, brother and wife could die, /And Id not feel a single moments pain (I, v, 18-20). This story of deceit leads the reader to believe that all will be lost and that evil will triumph over good. The events that occur in the play and the emotions that the characters experience parallel the events in our everyday lives. Such events include the power struggle between Orgon (the parent) and his children, about secret agreements, about reverse psychology and about relationships in general. Orgon has agreed to give his daughter Mariane to Valere in marriage but is now having second thoughts. He has decided that Mariane should wed Tartuffe. He believes that Tartuffe is the most suitable husband and tries to convince her. Youre a sweet girl Whom I hold dear, and think most highly of (II, i, 7). You can repay me, if youll cheerfully obey me (II, i, 9-10). Although everyone in the family is against this union he says I shall defy you all, and make it clear/ That Im the one who gives the orders here (III, vi, 57-58). Its a fathers privilege (II, i, 30). But beyond his threats he supports his feelings when he tells Mariane Daughter, well disregard this dunderhead. Just trust your fathers judgment. Oh, Im aware/ That I once promised you to young Valere; /But now I hear he gambles, which greatly shocks me; /Whats more, Ive doubts about his orthodoxy. /His visits to church, I note, are very few (II, ii, 65-70). Mariane is distraught and turns to Dorine, her ladys maid and friend. Dorine encourages Mariane to tell her father that one cannot love at a fathers whim; /That you shall marry for yourself, not him: /That since its you who are to be the bride, / Its you, not he, who must be satisfied; (II, iii, 8-11). But Mariane is afraid to go against her fathers wishes and answers Dorine, Ive bowed so long to Fathers strict control, I couldnt oppose him now, to save my soul (II, iii, 13-14). When I read this part of the play it was like I was reading a page from my own life. Like Mariane, I have a great deal of respect and love for my mother and stepdad who have always guided me down a safe and stable path. But we disagree strongly about the boy I am dating. Tom is a kind and thoughtful person. He is a good friend and can be trusted with confidences. He and I enjoy many of the same things but each of us is willing to learn about the others interests and hobbies. My mom and stepdad see things differently. They pointed out that Tom and I are of different religions and from very different backgrounds. My best friend Melissa, like Dorine, can see my side of the story and agrees that I should follow my heart. But I guess ultimately I am the one who will have to live with the consequences of my actions. Am I ready to do that? Tartuffe has completely seduced Orgon into believing that he is the most religious and devout human being in existence and believes that his charm will work on all members of Orgons family. Tartuffe makes a pass at Elmire, Orgons wife, it floods my heart with bliss/ To find myself alone with you like this. / For just this chance Ive prayed with all my power/ theres nothing I had rather do Than bare my inmost heart and soul to you (III, iii, 21-23, 27-28). Having professed his feelings he takes hold of her hands and presses her fingertips. When rebuked, he places his hand on her knee. Damis, Orgons son, tells his father of Tartuffes overtures. Father Let us advise you / that I surprised him with your wife, and heard His whole adulterous offer (III, vi, 1, 7-8). As the scene was unfolding I could feel the lecherous actions of this ungodly man. When I was at Nassau Community College last fall and then again in the spring I was stalked by a young man in my English class. Nothing has ever made me feel more uncomfortable or scared in my entire life. This guy would be standing near my car and would just stare at me. He would stand by my classroom and would just stare at me. He even once had the nerve to follow me into the Ladies Room. I told my English Professor and the campus security police. They said they would keep an eye out but could do nothing unless he actually physically attacked me or spoke to me directly. That was not very comforting because it seemed that they did not quite believe me. This sexual harassment was seduction at its worst. Tartuffe plays the scoundrel well. When given gifts by Orgon he insists he should Give him less I dont deserve it. The half, Sir, would suffice (I, v, 38). But Orgon does not see through these false words. Even when his son tells him of Tartuffes inappropriate behavior with his wife Orgon believes what he wants to. Tartuffe tells him Believe his story: the boy deserves your trust/ dont be deceived by hollow shows: /Im far, from being what men suppose (III, vi, 19, 24, 26). But Orgon insists that Tartuffe, is the honest and fair person he believes him to be and even gives him Clear deed and title to everything I own (III, vii, 38). This reverse psychology worked on Orgon and I hoped would work on my mom. One day when I was shopping with my mother, I badly wanted a pair of shoes that I saw in a fashion magazine and were expensive. I knew that my mom would not pay for them and would suggest that I get another pair of shoes that was more reasonably priced. When we got to the store she did exactly as I thought. She said no to the pair that I wanted because she really disliked them and picked out a different pair that she thought I might like. I said fine, whatever, and put a pout on my face because I was not getting the pair that I wanted. They really were not that bad and fit better than the expensive ones but they were not the trendy new expensive ones that I had my heart set on. But she was the one using reverse psychology. She told me that I could have the more expensive ones if I really wanted them. When she relented, I felt a little guilty. I put things into perspective and smiled. I agreed to the ones she picked out because they were more comfortable and I knew that after all the other things she had gotten me for school this would add another financial burden. However, after we paid for the pair of sneakers that was less money, she surprised me by offering to buy me a special pair of designer sandals that I desperately wanted, something she was planning all along. When Orgon finally accepts the truth about Tartuffe he must also accept the consequences of his actions. He is about to lose his estate and go to jail for keeping treasonous papers. He has decided that no one can be trusted. Cleante, Orgons brother-in-law, begs him not to jump between absurd extremes and to earn to distinguish virtue from pretense, / Be cautious in bestowing admiration, / And cultivate a sober moderation to err, if err one must,/ As you have done, upon the side of trust (V, ii, 37, 50-52, 56-57). My mom was a single parent for more than ten years and raised three children. Every decision rested on her shoulders. There were many times when she proved to be the stabilizing force in our lives by making difficult decisions about school, dating, driving and the like. We knew we could unconditionally count on her for love and guidance. She did, however, instill in all three of us the ability to make decisions. When I first started college I enrolled at SUNY Oswego. During the summer break I was very unhappy and torn about returning to school. There were not many Long Island kids at Oswego and fewer Jewish ones. I am the kind of student who needs to meet with my professors to help me get on track and some would not offer alternate office hours that would not conflict with my classes. Even so, I was more worried if my mom would be disappointed in me? Would I make new friends? Would my friends that that I had to come home? Would I be embarrassed about failing? I expected her to order me home because my grades were not as good as I had achieved in the past. On the other hand, I thought she might order me to stay since she had spent so much time, effort, and money getting me ready for out-of-town school. Instead, she ordered me to weigh the pros and cons and make a decision on my own. I insisted that she tell me what to do, but she held fast and offered no answer. She told me that the decision had to be mine. But having been raised in a household with her at the helm I had the ability to make a difficult grown-up decision. I decided to come hoe. She supported my decision and that decision turned out to be exactly right for me. I know I found my niche here at C. W. Post. Secrets can sometimes be troublesome and sometimes they are just meant to be shared between two people. When Tartuffe makes his sexual overture to Elmire, she asks him Arent you afraid that I may take a notion/ To tell my husband of your warm devotion. / But I shall be discreet about your lapse;/ Ill tell my husband nothing of whats occurred/If, in return, youll give your solemn word/ To advocate as forcefully as you can/ the marriage of Valere and Mariane (III, iii, 125-126, 136-140). When I came home from camp my mom and I entered into a secret agreement. My parents decided that I should help pay for half of the repairs on my car. It needed new tires, an inspection, and a new alarm. My mom knew how hard I worked all summer and that these repairs would take a big chunk out of my salary. We agreed that I would write out a check for the amount that was due and that she would reimburse me. She knew that if I paid for the repairs that I would not be able to take care of my personal needs and school expenses and that either way she would have to subsidize me. Orgon and his mother, Madame Pernelle, are each subjected to family pressure. Both believe in Tartuffe and will not listen to reason. As shown all along, Orgon does not want to hear any negatives about Tartuffe until his wife absolutely convinces him. But even Orgon cannot change his mothers mind. Madame Pernelle defends Tartuffe. She will not be swayed and insists that Till his guilt is clear, / A man deserves the benefit of the doubt. / You should have waited, to see how things turned out (V, iii, 45-47). Peer pressure is difficult to overcome. My first real experience with peer pressure was when I was away at school. My roommate was into marijuana and tried to convince me that a joint would enhance my outlook and I would begin to relax. My other friends tried to convince me that the bar scene was cool and that drinking would make me less up tight. But I know for me that drugs and alcohol are not for me. I am pleased to say that I did not give into peer pressure and Yes, I am the designated driver. As one can see, the events that the characters encounter in Molieres play Tartuffe are as timely today as when they were written. We can all identify and empathize in one way or another with his characters and the situations they find themselves in. Even though Orgon seems like a weak, uncaring father and husband, he ultimately shows his true love for his family and apologizes for his poor judgment. The play is a wonderful example of family life.

Use of Symbols in Sir Gawain and the Green Knight

Use of Symbols in Sir Gawain and the Green Knight â€Å"Sir Gawain and the Green Knight† is an ancient poem that tells the story of the exchanges between Sir Gawain and a mysterious Green Knight. Sir Gawain is a blood relative of King Arthur and a brave knight while the Green Knight is a disguised character who sets out to test his opponent. â€Å"Sir Gawain and the Green Knight† was authored in an unknown date in the late 1300s by an anonymous author.Advertising We will write a custom research paper sample on Use of Symbols in â€Å"Sir Gawain and the Green Knight† specifically for you for only $16.05 $11/page Learn More The unknown author who wrote â€Å"Sir Gawain and the Green Knight† is also associated with three other poems that were found in the manuscript that contained this poem. The setting of the poem has always been believed to be Northern England. The author of this poem (referred to as the Gawain-poet in this paper) uses several stylistic devices that make this poem an outstanding work of literature. The poet uses several symbols in the poem to the benefit of the readers. The symbols that are used in â€Å"Sir Gawain and the Green Knight† help the Gawain-poet to instill deeper meanings to this literary piece. This essay explores the symbols that are used in Sir Gawain and the Green Knight and how they contribute towards the revelation of the poem’s meaning. The poem begins by narrating the events that are going on in King Arthur’s court during the new-year festivities. A mysterious character, the Green Knight, arrives at the King’s court albeit uninvited. The Green Knight proceeds to offer a challenge to all the feast attendees; any brave knight who is present at the court will have the opportunity to strike the Green Knight with an axe but in one year and a day’s time the volunteering knight would have to withstand a similar challenge. King Arthur steps forward and accepts the challenge but Gawain intercepts the King and takes up the challenge himself. Gawain carries on the challenge by striking the Green Knight’s head with an axe and manages to severe it. However, in a strange turn of events the Green Knight bends down and picks up his severed head. The Knight then reminds Gawain to honor his end of the deal by showing up to the Green Chapel to receive a similar challenge. Approximately a year after this encounter, Sir Gawain leaves for the Green Chapel to honor his end of the deal. The Gawain-poet details the adventures of Gawain throughout his journey in the rest of the poem.Advertising Looking for research paper on british literature? Let's see if we can help you! Get your first paper with 15% OFF Learn More One of the most prominent symbols that are used in this poem is Gawain’s shield and pentangle. The shield is a tool of protection especially for people who engage in armed combat. The pentangle that is contained in the shield is specific to the wearer (Sir Gawain). Therefore, the pentangle is a symbol of the virtues and values that are held by Gawain in the course of his Knighthood. According to the poem, the pentangle is a five-pointed-star that traces its origins to King Solomon. In most ancient texts, the pentangle is often a symbol of truth or a magical seal (Green 123). The interlocking nature of the pentangle symbolizes the complexity of human virtues. In the context of the â€Å"Sir Gawain and the Green Knight†, the pentangle brings together the influence of â€Å"the five virtues, the five wounds of Christ, the five senses, the five joys of Mary the mother of Jesus, and the five fingers (Besserman 220). Consequently, it is apparent that as a knight, Gawain also seeks his moral, physical, and spiritual strengths from other places. Gawain’s strengths and virtues are interwoven like the triangles in the pentangle. The endless pattern that is found in the pentangle echoes the perfection of Gawain ch aracter. For instance, when all the other knights are afraid of the Green Knight’s challenge he voluntary rescues the King from possible failure or humiliation. Solomon is said to have used the pentangle as a personal magic seal. However, later on Solomon became a symbol of wisdom, kingship, and might. The similarities between Solomon and Gawain’s use of the pentangle are that both personalities had flaws. At the end, Solomon turned away from God and eventually lost his kingdom while Gawain refused to honor a promise he made to his host. The Gawain-poet emphasizes the significance of the connection between Gawain and the pentangle. According to Professor Burrow, several lines in the poem are dedicated to establishing this connection. For example, the poet mentions that the pentangle is a symbol of fidelity or ‘trawpe’ that associates Gawain with the traits of faithfulness and fidelity. The poet then concludes that the object is befitting for the main chara cter (Morgan 779). The symbol of the pentangle helps in developing the themes of bravery and selflessness. These two concepts are presented from a Christian point of view and hence the pentangle is a symbol of fidelity and faithfulness.Advertising We will write a custom research paper sample on Use of Symbols in â€Å"Sir Gawain and the Green Knight† specifically for you for only $16.05 $11/page Learn More Color green is a symbol with several possible interpretations. The main antagonist in â€Å"Sir Gawain and the Green Knight† is the Green Knight. The Green Knight is presented by the poet as a mystical character with striking features. This character is noted to be green in color. In addition, the Green Knight has a green horse, green skin, a green beard, green clothes, a green-gold axe, and green hair. The portrayal of a completely green knight highlights the peculiar nature of Green Knight’s presence. In addition, the Green Knightâ €™s color uniformity suggests that he is a uniform character. Several analysts have debated about the symbolism of color green as used by the Gawain-poet. Some scholars have proposed that the Green Knight is a symbol of the god of vegetation and nature. According to Basserman, the green color of the Green Knight symbolizes the â€Å"dying and rising vegetation god† (220). Other medieval texts have also made references to green men. In some instances, a green man symbolizes a ‘wild man’ while at other times he symbolizes the ‘evil man’. The Gawain-poet combines both symbols because at the beginning of the poem the Green Knight is portrayed as a character with evil motives. However, by the end of the poem the Green Knight is portrayed as a straightforward character. Most scholars are in agreement over the fact that in traditional-English folklore the color green mostly symbolizes fertility and rebirth. In the poem, green is presented as a pure colo r except for the green-gold girdle. The mixture of green and gold is a symbol of change in the form of passing youth. The green color used in the girdle first serves a symbol of immortality. When Gawain is humiliated by his behaviors, he adorns the green girdle as a symbol of cowardice and shame. However, the Camelot knights finally adorn the green girdle as a symbol of honor. All these changes elaborate the ambiguity of color green as a literary symbol. The poem also employs the symbol of an axe that is held by the Green Knight during his entry to the king’s court. During the medieval times, the axe was a symbol of execution. Consequently, when the Green Knight is holding an axe he symbolizes the executioner. When the Green Knight enters the palace, he is holding an axe but he offers to be executed first.Advertising Looking for research paper on british literature? Let's see if we can help you! Get your first paper with 15% OFF Learn More This makes the Green Knight a strange and an unusual executioner. When the Green Knight picks up his severed head and rides away, it becomes clear that he is an extraordinary executioner, one who cannot die. In medieval texts, death is known as the only executioner who cannot die (Besserman 220). Apart from the axe, the Green Knight is also holding a holly bob. In medieval England hollies were constantly associated with death and ghosts who would often come back to haunt their former residences. Some medieval sources claim that it was â€Å"a well known fact within the English tradition that a holly bob carried into a house before Christmas foretells death in the coming year† (Krappe 214). Therefore, when the Green Knight enters holding an axe and a holly bob, his symbol as the executioner who foretells death is complete. The green girdle is another symbol that has ambiguous characteristics. The symbol of the girdle is like the one of color green and it keeps changing through out the poem. At first, the Gawain is given the girdle by his host’s wife with the promise that it has magical elements and it will make him immortal. However, when the identity of the Green Knight is revealed to be that of Gawain’s former host, the girdle instantly symbolizes cowardice and shame. Gawain resolves to wear the girdle for the rest of his life as a symbol of his shameful and cowardly act. However, when Gawain arrives at Camelot he finds all the other knights wearing the girdle as a symbol of triumph and honor (Tolkien 121). Given the poem’s religious undertones, the Gawain-poet might have used the symbol of the girdle as a parallel to the crown of thorns that was worn by Jesus during crucifixion. Jesus’ crown of thorns was a symbol of both humiliation and triumph. Furthermore, the crown of thorns signified the victory of Jesus after he had gone through turbulent times. Gawain goes through tough experiences that are similar to the ones that Je sus went through and in the end he receives a symbolic girdle. A thorough analysis of the symbols that are used in â€Å"Sir Gawain and the Green Knight† reveals that this poem contains several hidden meanings. These symbols also reveal that the Gawain-poet employs a strong religious theme. The poem also lacks a sole and definite meaning. Instead, the Gawain-poet chooses to indulge the readers in dual-meaning symbols. Symbols are also used to portray the weaknesses of mankind in the face of tribulations. Most of the symbols in this story dwell on the subjects of death, human triumph, defeat, temptation, and honor. The dual meanings in some of the symbols that are used in this poem suggest that the poet is not ready to pass judgments. A thorough analysis of â€Å"Sir Gawain and the Green Knight† indicates that symbols are prevalent in the poem and the Gawain-poet intended to use these symbols as tools of hidden meanings.

Human resource management Essay Example | Topics and Well Written Essays - 750 words - 4

Human resource management - Essay Example d organizing an effective workforce that is able to make valuable contribution of promoting a sense of togetherness and collective responsibility that reflects in the increased output and improved performance outcome of the organizational goals and objectives. Understanding of organizational behaviour is essential ingredient of organizational communication which motivates people to better performance, leading to higher productivity. Effective communication facilitates better understanding of cross cultural values and cuts across the multi cultural layer of the organization and is the key to enhance the overall performance of the organization. Schwenk says that ‘employee’s absolute commitment to a shared vision of change is seen by many leaders/ change agents as so important for their organization’s continued survival’ (Schwenk, 1997, p4). It therefore implies that high morale of the workforce results in improved performance outcome of the organization. Maslow argues that ‘People’s behaviours are guided or motivated by a sequence of needs’ comprising of self actualization, status, acknowledgement, reward and retention (Schwalbe, 2007). Hence, managerial leadership that encourages and promotes proactive participation and collective decision making significantly inspires the workforce to improved performance outcome. Indeed, Quick et al. have also stressed ‘it is possible that psychological well-being and employee performance are related’ (Quick et al, 1997). In CCB International, the theoretical aspect of human resource management is well understood by the senior management and CEO but not taken up with sensitive approach. The concept of workforce as human capital is accepted by the Managing director but the Head of HR department feels that morale building and team spirit can be achieved through joint activities and are not vital part of organizational culture. He also argues that HR strategy is limited to meeting the HR requirements and may

King arthur Essay Example | Topics and Well Written Essays - 1000 words

King arthur - Essay Example According to legend, he was the son of Uther Pendragon, king of Britain, and Ygraine of Cornwall. During his childhood, Arthur's identity was kept anonymous. Upon his maturity, he was abruptly presented to the people as their king and became a prudent and brave ruler ("Microsoft Encarta"). On the other hand, in the early Latin chronicles, Arthur is characterized as a "dux bellorum," i.e. a military leader rather than a king or emperor ("Camelot Project"). Despite the varying depiction, Arthur consistently appears as the epitome of ideal kingship ("Wikipedia"). Based on the Arthurian romances that gained popularity in the 12th century, Arthur gained the throne as he was the only one who had successfully withdrawn the Excalibur, a magical sword, from a stone. Many others attempted but failed since this act could not be accomplished apart from the "true king." This implied that Arthur was indeed the divinely appointed king and the true heir of Uther Pendragon ("Wikipedia"). He then established a court at Camelot, which is believed to be the modern Caerleon on the southern border of Wales or the great hill fort at South Cadbury in Somerset ("The New Dictionary of Cultural Literacy"). At Camelot, Arthur gathered the Knights of the Round Table, which were comprised of Sir Aglova... ne; Sir Ector de Maris, son of King Ban of Benwick; Sir Florence, son of Sir Gawain; Sir Gaheris; Sir Galahad, Sir Lancelot's son and the hero of the quest for the Holy Grail; Sir Gareth; Sir Gawain, Arthur's nephew, who at some points appeared as the embodiment of knightly courtesy and bitter opponent of Lancelot; Sir Geraint; Sir Kay, Arthur's villainous foster brother; Sir Lamorak; Sir Lancelot; Sir Lucan; Sir Palamedes the Saracen; Sir Percival; Sir Tristan; and Sir Yvain, son of King Uriens of Gore (Lacy). These knights were awarded the highest order of chivalry at the court of King Arthur as narrated in the literary cycle, the Matter of Britain. According to Sir Thomas Malory, the knights abided by a set of rules called the Code of Chivalry. Provisions of this code include not committing outrage or murder; fleeing treason; not succumbing to cruelty but instead giving mercy to those who ask; helping and never forcing ladies, gentlewomen or widows; and not taking up wicked battles for love or worldly goods. Aside from Arthur and his knights, the Arthurian legend also featured notable characters such as Merlin, a powerful wizard possessing the gifts of prophesy and metamorphosis who partook in the court at Camelot and revealed the existence of the Holy Grail to Arthur, and Queen Guinevere, the wife of Arthur. Moreover, it gives an account of the knights' numerous quests, perhaps the most famous of which is the search for the Holy Grail ("Wikipedia"), and Arthur's wars and victories, which extended to the European continent where he triumphantly fought the Roman Empire forces ("Microsoft Encarta"). One of the main themes in the Arthurian legend is the downfall of Arthur's kingdom, which is primarily attributed to two reasons. In the chronicle tradition, the

The United States and the International Criminal Court Research Paper

The United States and the International Criminal Court - Research Paper Example It officially came into existence in July 2002. This also marked the day when the President also signed the American Service members’ Protection Act (ASPA) restricting the U.S. from giving assistance to the ICC. The international norms as well as institutions have a significant effect on the states and individuals. The ICC is the world’s first permanent judicial body with utmost jurisdiction to try those individuals who were accused of war crimes or for that matter, crime against humanity (Eisea 2002). A large part of the United States foreign policy is moving at a smooth pace. The situation in the United States and all over the world had begun to deteriorate as the crime rate started to increase. It is for this reason that the majority of the international states had decided to create an international court dealing with mass atrocities. This would not only help solve various criminal acts but also prohibit the severe violation of human rights all across the world. There have been instances in the past whereby the United States underwent a great challenge from the International Criminal Court. United Nations and many other democratic nations have openly welcomed and supported the ICC for its performance, although the United States initially voted against the Statute of the International Criminal Court the reason being that ICC may assert jurisdiction over the U.S. soldiers charged with crime which would be a result of legitimate uses of force (Eisea 2002). As late as in 2005 the U nited States decided not to block a sensitive Security Council resolution indicating the situation in Darfur region of Sudan to the ICC prosecutor. The ICC depends on the support as well as cooperation by the States and other international organization (Taft & Wald 2009). The International Criminal Court jurisdiction extends to the most heinous crimes committed at international level. It thus becomes important for two reasons. It offers an advanced means to revise the foreign policies through alternatives especially after World War II. It extends its reach by offering substantial hope and underscoring the significance of international law (Sewall & Kaysen 2000). Even if the ICC acts alone or with a national court, it can provide a model for fair and deliberate administration of justice. With all the qualities it is equipped with, it faces countless uncertainties with regard to how it enforces justice and defines the interest that justice will serve. United States however is not conc erned with these issues faces by the International Criminal Court. The main concerns that the United States shows towards the Court are objections in the legal framework on which the ICC is built. ICC must not be bound on all states irrespective of the war crimes each one of them have. Secondly the ICC’s definitions of crimes such as genocide, war crimes and those perpetrated against humanity are narrower than the international law. The Rome Statute was seriously flawed according

Science vs. Religion Essay Example for Free

Science vs. Religion Essay The debate between religion and science has been going on for years, clashing together with different ideologies. The argument combines historical and philosophical approaches to contest to each side, battling to disprove each other. While religion is based on faith, using the will of God to guide them in their observations, scientists use experiments to find discoveries based on facts. The conflict between religion and science hasn’t been fiery in modern times, compared to the years where science was inferior to religion, but the topic has still been brought up in discussion. Can someone be both a scientist and a religious person? Although they may both pursue knowledge, there methodologies are completely different, pitting each other into heated discussions. In our past lecture with Brother Guy Consolmagno, he argues that Christianity isn’t completely based on faith in God. The church is also continuously studying the universe, like scientists, trying to learn more about our origins. Comparable to science, ideals in the church changes, and aren’t always set in stone. The Bible may be the guide for most religious people, but there are also different interpretations of the Bible that people find to counteract certain claims. Guy uses evidence that the first medieval Church universities started the modern study of astronomy. The university learned: grammar, rhetoric, and dialectic, arithmetic, geometry, astronomy, and music courses, which showed that it was like any other university teaching students for a better career. The university may be Christian based, but it didn’t ignore what science offered them. According to Guy, Jesuits run 25% of all observations in Europe. They helped create the definition of a â€Å"year,† based on our four seasons. Despite the differences between religion and science, Guy believes that we can comingle ideas from both sides to progress our studies of the universe even further. (Consolmagno) One of the topics in The Constant Fire introduces James Clerk Maxwell, one of the great physicists in his time, and his view of religion and science co-existing with each other. Maxwell formulated equations that explained electric and magnetic fields and the unification of these concepts into electromagnetism. Maxwell’s equations and mathematical laws are the reason why we have radio, television, and all electronic technology today; although he constructed scientific laws for his devotion to science, he was also a devout Christian. â€Å"I believe†¦that Man’s chief end is to glorify God and to enjoy him forever. † (Maxwell) He attended church regularly, read scripture before going to sleep at night, and even committed the entire psalms to memory. It showed that his religious belief was unyielding, despite his scientific advances in society. At the same time I think that each individual man should do all he can to impress his own mind with the extent, the order, and unity of the universe, and should carry these ideas with him as he reads [the Bible]. † (Maxwell) Learning about the universe through a different perspective doesn’t waver doubt; instead, it enriches spiritual understanding. Maxwell set an example showing how his experience in science was an aspiring journey to glorify his God. (Frank) The Constant Fire also explains Isaac Newton’s perception of his work towards science contrary to his religious beliefs. Newton asserted himself as a â€Å"priest of nature. † Like any religious person, he believed there was a God of absolute power. Although, he also believed that his work was exploring God’s greatness, making science a way of explaining his creation. â€Å"It is the perfection of God’s works that they are all done with the greatest simplicity. He is the God of order amp; not confusion. † (Newton) Both scientific philosophy and religion were inseparable, as both concepts bounced off each other. Even coming from one of the greatest scientists in the orld, like James Maxell, Newton concluded that there ironically was no warfare between science and religion. (Frank) Science comes from the creativity of an individual making up a new hypothesis. Religion comes from varied interpretations of how they view the spiritual being they worship. We don’t have enough evidence from the universe to commit to a godless path, and we are too knowledgeable enough to pledge to a specific religious ideal. I believe there is such thing as a middle ground: taking the possibility of new ideas and building an equal foundation. I still keep to the constitution of scientific theory composing our world, but I also keep multiple hypotheses in mind. We should be open-minded, and explore the different possibilities of the unfathomable unknowns of our universe. I’m not afraid to ask the lingering question science and religions try to explain.

Theories of Crime | Introduction

Theories of Crime | Introduction There are many theories of crime which fit into four different models each explaining crime through varied approaches, in this essay I will be discussing the weakest of these theoretical explanations of crime and the strongest. The weakest theory of crime is Biological Positivism which is part of the Predestined Actor Model which is a positivist model explaining criminal behaviour based on scientific factors beyond a persons control. Biological positivism has been heavily criticised by many criminologists due to their explanations that the internal factors of a person is what causes crime, this will be explored further and proven to be the weakest theory throughout the essay. The strongest theory of crime is Left Realism, which is an integrated explanation. This theory takes into account elements of other approaches and realises that there are multiple causes of crime therefore making it one of the strongest theoretical explanations, this will be elaborated on in the body of the essa y and will be further proven why it is the strongest of all the theories. Throughout the essay I will be addressing the main points, the key thinkers, their explanations of crime and why it was chosen for each theory, which will then conclude in support of my claim of the weakest and strongest theories. Lombroso was the founding father of biological positivism and his theory suggested that people were born criminal; this explanation was influence by Darwins work on evolution and atavism. Although he was a biological positivist his work gradually turned towards environmental factors therefore suggesting that biological factors as the cause of criminality was not enough of an explanation and poverty for example also became influential. Lombroso was interested in criminal behaviour and categorized criminals as born criminals, insane criminals, occasional criminals and criminals of passions. He set the scene for all positivist work and other biological positivists based their work on Lombrosos findings. However Lombrosos work has been criticised, as it used outdated methodology which was very basic therefore he was unable to create any meaningful conclusions. Furthermore he did not consider female offenders, any criminal acts which were carried out by women he disregarded and stated tha t the men were responsible for the female involvement, therefore lacking in validity (Burke, 2009). Matza in 1964 went on to say that a criminal is a specific type of person, that is different to those that are not criminals and that crime occurs due to factors outside of their control. However, this then ignores the aspect that humans have free will to commit crimes therefore disagreeing with theories in the rational actor model like Classical theory, which states that people choose to commit crimes. There are many theories in biological positivism which all state that individuals are compelled to commit crime as it is part of their biological make-up, such as physical factors, theories related to the body, chromosomal anomalies, etc. however these have be criticised as you will see below. Physical type theories were the first to come out and this was based on the idea that criminals stand out based on of their appearance. Lombroso did research on atavism as mentioned above, that criminals are born criminal and show signs of criminal throwbacks for example long ears and sloping foreheads. As a result of this, people speculated that those with physical atavistic characteristics were criminals and used it as a prevention tactic. However this only related to a small amount of criminals and therefore is not very reliable and many with these characteristics could be wrongly accused of criminality. In todays society Lombrosos work is considered outdated and discredited due to the theory that a persons physical appearance increases the likelihood of them being a criminal, this is seen as absurd and meaningless, hence perceived as a weak theory. Phrenology, which is the study of skulls was also used to explain crime, Gall stated that by looking at the shape and bums of a skull can indicate a persons character and specified that the area above the right ear determines how violent that person is. This theory has been criticised immensely along with physiognomy, which tells a persons character through facial featured, due to its lack of credibility. There is not enough substantial evidence to prove this theory amongst a vast population because people are individuals with an individual biological make-up (Maguire, 1997). Sheldon has done some similar work on linking body shape to behaviour, (his theory of somatypes) and identified three forms of body types which relate to certain personalities. He established that offending behaviour and crime is linked with mesomorphs, who are muscular and athletic with an aggressive personality. However it does not consider that these types of people may be targeted by the police more than the other two body types therefore is supporting his theory as those athletic built individuals are getting caught, where as other body types are not. These physical theories are very weak as they are ignoring different aspects of the interaction between the physical characteristics of the person and their social circumstances. (Burke, 2009:74) People from poor families and areas may have a poor diet therefore causing them to be small, while young people working manual jobs are more likely to be muscular. These people are over-represented with criminals, which could be explained by socio-cultures not via biological factors (Burke, 2009). Furthermore, to support the statement that biological positivism is a weak theory, Sheldons work was follow up by a Cambridge Study in Delinquent Development and found there was no physical difference between offenders and non offenders, therefore suggesting there is no reliability due to the inconsistency. Further criticisms of this theory are based on its methodology, as the sample of offenders and non offenders are not representative to society as mentioned above it does not account for those who do not get caught, it ignored the sifting process in the criminal justice system. It also disregards interaction with the environment, as those individuals with physical stigmas may retaliate against their social environment and labels given to them therefore living up to the expectation leading to a self fulfilling prophecy (Taylor, Walton, Young, 1973). Chromosomal Anomalies is another category of biological theory criminologists have used to explain crime, it looks at the link between abnormal chromosomes and criminal behaviour. A normal female complement is XX and male is XY, an abnormal complement is when there are chromosomes missing or there are too many for example the XYY. Brown in 1962 found that those with sex chromosome abnormalities had higher rates of delinquency than his other patients. Casey et al (1966) followed on from his work and did the first major studies at a secure hospital and found supporting results for men with an extra Y chromosome as well as them being taller and having low intelligence (Taylor, Walton, Young, 1973). The limitations for this theory are similar to that of the body type category, for example those with an extra Y chromosome may be taller and well built therefore targeted and treated harsher by agents of the criminal justice system like the police and judges. Further limitations which makes this theory the weakest, is that there are many individuals that are normal and do not behave criminally in society that have extra chromosomes, therefore suggesting that others factors have to be involved. In addition this theory also ignored the fact that those young men with an extra Y chromosome came from a working class background, therefore the cause of criminality could be due to their exploitation from the ruling class not because of chromosomes. Marxist theory would agree that the cause of criminality was a result of capitalist society and not chromosomes that are not identifiable and unable to predict criminal behaviour. Biological positivists also explained criminality as genetically inherited; they suggested that a criminal gene can be passed on through the family just like physical characteristics. To test this theory they used three sources of data, studies of criminal families, studies of twins and studies of adopted persons. All three sources claimed that criminal behaviour was inherited rather than environmental, however family studies did not considered the effect of an absent parent lending to criminality. In twin studies they could not identify whether criminality was influenced more by environmental or biological factors however did mention that biological theory on its own to explain crime is not enough, therefore is a weak theory to base criminal explanations on. This was also reiterated in adoption studies emphasising that environmental factors play a role and add to the reliability of the theory, therefore showing the weaknesses of the biological theory when it is used to explain crime on its own (Wiley, 1996). There are many weaknesses in the categories within biological theory, from the methods used by criminologists to their shortcomings in ignoring certain aspects including the three data sources that explained inherited criminal characteristics. The main limitations in biological positivism occur throughout all the categories even biochemical explanations such as hormone imbalances and substance abuse which has not been discussed in detail. The reason this theory was chosen as the weakest is due to it many limitations; criminologist largely discredit this approach as it is nowadays seen as outdated and not relevant, therefore there are many better explanation to crime that can be proven. Biological theory only looks at criminality from one approach which is seen as a very over determined view of human actions and a more integrated approach would explain crime better for example the more recent socio-biological explanation of crime. It only explains criminal behaviour effectively in a m inority of offenders and has considerably more limitations as mentioned above. This weakest theory also cannot explain the variation in crime rates and offers no explanation to why and how laws arise. A further reason it was chosen as the worst, was due to the unethical and harsh treatments to prevent crime which in the USA, even results in death, genetic selection and sterilisation. The strongest theoretical explanation of crime is left realism. This theory is chosen as the strongest because unlike biological positivism it does consider other factors and is an integrated model which recognises that there are many causes of crime and contains essential parts from all three models of crime. Jock Young had a major turnaround which altered criminological thinking to the emergence of left realism; when crime rates were meant to decrease due to economic restructuring and improved conditions and instead actually increased, with the increased awareness of victims of crimes and crimes that were previously invisible, and finally a growing public demand and disapproval in efficiency of public service (Newburn, 2007). This new criminology from the left political view, with criminologists such as Young, Lea and Matthews believed crime is a real issue and not socially constructed therefore it needs to be addressed. Left realism is the strongest theory as it takes into account the immediate fears that people have and seek to deal with them (Burke, 2009:264), such as street crimes in high offending areas as those living there are caught right in the middle of it. As mentioned above this theory is seen as theoretically strong as it recognises various causes of crime that are credited. The relationship individuals have with the police could be a cause of crime, if the police are harassing people therefore causing them to retaliate or feel helpless; this will drives them to offend. This theory is supported by labelling theory which makes it stronger because instead of theories disagreeing with the causes it agrees therefore creating validity. The police can also cause moral panics in society which can lead to further criminal behaviour; this could be a distraction by capitalist so that the working class are not aware of the real issues that they should be concerned about, this strength allows the individual to be aware of the capitalist system and the exploitation by the ruling class therefore can avoid crime. A key element of left realism is relative deprivation as a cause of crime. People measure their situation for example what they have got, (money and jobs) against the expectation that society creates. When individuals are unable to reach that expectation they may turn to crime in order to achieve it, this is the theory of anomie suggested by Merton. This explanation adds to the strength of this theory as it highlights economic and social factors of crime. Another key element is subculture, Lea and Youngs subcultural model explains how subcultures are used as a response to problems. Those who are unable to adapt to middle class values create subcultures that include people that share their norms and values so they are no longer frustrated. This therefore can be a response to the problem for the working class individuals; however this subculture may create norms and values to suit the group which may include criminal acts as a way of rebellion against the system (Lea, 2002). The final key element is marginalisation, as certain groups lived on the margins of society and are not accepted by others, consequently turning to crime. All these explanations of crime are some of the best from other theories and now under one theory therefore this is the strongest theoretical explanation of crime. An additional reason this is chosen as the strongest theory is because it provides a solution to crime and not just the causes, this is shown with the square of crime. Left realists state that crime is a gathering of the following four factors and the relationships between the four factors determine the effectiveness of that relationship to preventing crime. The first of the four factor, is the state; where the agents of the system label individuals as offenders which is a major factor of recidivism, the second is the victim; who may encourage criminal behaviour due to lack of defence or through repeated lifestyle (routine activity theory), the third is society; where formal and informal social controls occur and the fourth is the offender; how often they commit crimes and the type of offences, etc. (Burke, 2009). To prevent crime, you have to interfere at each point of the square. For example, in the state the police should have more effective policing and the courts should not make preconceptions. The victim should be more responsible for their protection and maybe change their daily routines regularly. The public (society) to ensure that the required socialisation is taking place in primary years and finally the offenders should exercise their free will and decide not to offend. A criticism of left realism, is that the theory is mainly based on previous approaches. However this can be considered as a positive factor, as the theory is hard to criticise due to the fact it has elements from all modules therefore accounts for many explanations and was chosen as the strongest theory. Further advantages includes how it seeks realistic policies to tackle crime problems and how left realism is about prevention not control, therefore left realists believe that if you punish it will lead to marginalisation, so consequently prevention is better.
