Community mental health service Essay

Describe how three key professionals could be involved in planning support for individuals/Mr. Ali There are three key professionals working with Mr. Ali and supporting him through his decisions. They are also working together with each other to put together a support plan for Mr. Ali. The three key professionals are; a community psychiatric nurse, support worker and dietician. Each has a different role in the planning support for Mr. Ali as they are all supporting Mr. Ali with different aspects of his health and well-being. A Community Psychiatric Nurse is fully trained and has many years experience in a hospital setting before going out into the community. Their experience would have been on psychiatric wards in hospitals. The role of the Community Psychiatric Nurse is to visit people in the community, usually in the patient’s own home but can also be clinic based. CPN’s are normally the patient’s first point of contact as they are there to support people who are experiencing a difficult time in their lives. They also visit patients in the community who are in good health to ensure they are okay. A CPN administers medication to patients and ensure they know the reason to why they are taking then and when they should take them. A CPN does not only support the patient but also family, friends and carers. This role is valuable as it helps them to understand and cope with any illnesses the patient has. CPN’s also take referrals from GP’s, psychiatrists and inpatient wards as the CPN will support the patient and help them get back out into the community and from then on the CPN is usually the patients key-worker. In regards to Mr. Ali, the community psychiatric nurse will visit him at home to ensure his emotional and psychological state is not going to be jeopardised due to him taking part in the sponsored walk. The CPN will also ensure Mr. Ali is still taking his medication correctly and support him through any tough times he is facing. The CPN’s role as a nurse and key-worker when participating in the planning of Mr. Ali’s support plan is, to review Mr. Ali’s progress and assess if all of Mr. Ali’s needs are being addressed. This involves, getting feedback from Mr. Ali about how positive or negative the help and support is that he is receiving from the mental health team. The key-worker can be anyone who is a member of the community mental health team; a psychiatrist, CPN, Occupational Therapist, Social Worker or psychologist. A support worker is someone who supports people with different need in their everyday lives. They support them in many ways and in many situations. They focus on the needs of the service users by supporting them, giving time to the service user and promote their recovery or support them through illness. The role of a support worker is to; promote the independence of the service user, provide companionship and friendships whilst providing practical and regular support. A support worker will provide support with daily living and facilitate people living normal lives. A support worker plays a huge role in any service user’s life and helps them gain access to resources such as; day centres, support groups etc. If a service user was to deteriorate then their support worker will help identify this and then supporting the service user when they are going through treatment. Health promotion information is also provided by a support worker. In regards to Mr. Ali, a support worker working with mental health is known as a STR; a support, time and recovery worker. The STR will work as a team who focuses directly on Mr. Ali and provide mental health services. Even though Mr. Ali lives independently, his STR will support him to keep his independence. The STR would need to have a good relationship with Mr. Ali, providing companionship and friendship, and then they will be able to provide regular and practical support. Mr.Ali attends a day centre and to gain access to this, the STR would have helped Mr. Ali. The STR will give Mr. Ali all the support he need with daily living whilst facilitating Mr. Ali to live an ordinary life. If Mr. Ali was to start having a relapse his STR would help identify the early signs and report it to other health professionals involved in Mr. Ali’s care and support. The STR would the support Mr. Ali with any treatment he is involved in. When Mr. Ali attends the day centre, his support worker may be with him at times to provide emotional support and could also act as an advocate. As Mr. Ali’s STR, they will be there to support Mr. Ali through anything he finds difficult in his daily life and support him with tasks when needed. The STR will put their views across to other professionals and Mr. Ali when in the process of creating a support plan. He will be able to pass on his concerns about Mr. Ali and also what he thinks Mr. Ali’s strengths are. The STR will put a lot of information into a support plan as they would know Mr. Ali best due to building a strong compassionate friendship and due to being more involved in Mr. Ali’s personal life than other professionals. Whilst being involved in the support plan the STR will promote Mr. Ali’s rights, maintain confidentiality and promote equal opportunities, ensuring Mr. Ali is being treated with respect and dignity, which is part of ethical practice. A dietician is a trained professional who enables and empowers people to make informed and practical choices about the food they eat and lifestyle choices. They are trained in hospital and community settings and usually employed by the NHS. They can also work in the food industry research and education, and also on a freelance basis. Dieticians must be registered before working with anyone who is referred to them. Their role includes going through a practical application of nutrition with individuals, promoting the well-being of both individuals and the community; this will help to prevent nutrition related problems. Dieticians can also diagnose individuals with nutrition related problems and disease, and are also involved with dietary treatment of disease. Their main responsibilities include; working with individuals with special dietary needs, evaluating and improving treatments. They also use a social marketing approach to inform the public about nutrition and offer unbiased advice. They are there to also educate patients, clients, other health professionals and groups in the community. The use of mass media is used a lot by dieticians; leaflets, adverts, posters, billboards, radio advertisements, television adverts and many more forms of media are used and this is how dieticians promote well-being, inform the public, educate and give advice. In regards to Mr. Ali, he wants to become healthier as he wants to help raise money for the day centre he attends. He will be helping raise the money by participating in a 20 mile sponsored walk. He has taken this very seriously and wants to do his absolute best in achieving his goal. The event is taking place in three months time and within this time Mr. Ali wants to gradually improve his walking distance. The main support he wants is with his diet. He wants support and advice on healthy eating; this will be part of his preparations. He wants to know what meals, drinks and snacks are best for him to keep his energy levels up but not empty calories which will make him gain weight. To help Mr. Ali with this, the dietician will advise him on what is a good way to maintain his weight and raise his energy levels. Dieticians sometimes do this by working with the service user to create a healthy eating plan. This will consist of what Mr. Ali will eat each day, Mr. Ali will be involved in the whole process. Mr. Ali will be given leaflets full of nutritional advice and the dietician will also talk to Mr. Ali about any bad habits he has, what foods he eats more of, what his food weaknesses are and if he does any physical exercise. The dietician would have to take into consideration that Mr. Ali cannot be pushed too hard or become distressed due to his mental health illness. The dietician needs to respect Mr. Ali’s choice and treat him with dignity. Mr. Ali’s rights should not be infringed and the dietician should not use and abuse their power; just because Mr. Ali has come to the dietician for support and advice, it does not mean the dietician can control what Mr. Ali eats or controls what he does in his personal life. All the dietician should do is give advice and support Mr. Ali with his preparations. The dietician can review Mr. Ali’s progress before the event begins. They can do this when they feel Mr. Ali will need more advice and support. It may start off as every two weeks then move to once a month depending on his progress and health. The role of the dietician when participating in the process of creating Mr. Ali’s support plan is, to put forward his thoughts on how he thinks the healthy eating and preparation for the 20 mile sponsored walk will affect his health. He can put forward whether they think it would be too much pressure on Mr. Ali or if it will be for his mental and emotional state. Together all three professionals can determine, with Mr. Ali present, what the best option is for Mr. Ali and how he can participate in the event without it affecting his health and well-being. When working together all professionals must consider Mr. Ali’s individuals rights and treat him as an individual. If he is not treated with respect and dignity, or not treated as an individual then he will feel his personal identity has been stripped from him. Taking a holistic approach will ensure that all Mr. Ali receiving a person centred care.

â€Å"A stich in time saves nine. † Prevention is always better than cure, if we know that something with the passage of time might become dangerous then it better to take a precautionary step to combat the danger. So how many times you heard your parents and grandparents say this to you- take precaution dear and don’t give your problems a chance to arrive. So better work now and take precaution instead of fixing the damage later. This phase is applicable in many fields of life: If you are student then you should study every day, but generally all the confusion arises when you study only during exam. When you ignore your study in the early stages then you end up working hard during your examinations and risk your success. There is no need to gamble with your success if you do your studies appropriately on time. You should immediately go to a doctor and start your treatment, if there are certain visible symptoms of a disease, before getting diagnosed with that disease. There have been many cancer cases where the patient did not take his health seriously and later on with further deterioration of his health, he comes to know that he is suffering from cancer and is at the second or third stage. Had he been to the doctor earlier and diagnosed with his disease then he could have been easily cured in the first stage. Even in the case of other diseases early detection helps in taking better preventive measures. Thinking that the disease will cure itself or avoiding doctor visit may result in increase of the problem and expenses even endanger your life. We can take precaution methods by choosing healthy diet and making it a point to exercise regularly. Regular exercise and good nutritious food will make us less prone to diseases, and will also result in a healthy heart, mind and body. Preventive measures taken in work areas also lessen the intensity of suffering. For example if you focus on the market you can save yourself from financial catastrophe by perceiving the future losses. Preventive measure also helps in controlling population. Wise man always use this formula for the success, they never wait for the deadline to come near to start their work, instead they finish their work before deadline, this gives them time to solve any unseen problem that might occur during the process of their work. It is an old saying which holds true in daily life: No man is perfect we all do mistakes. But with the help of act of Prevention one can avoid doing many disasters, complexities, confusion and destruction. We can check ourselves from doing something by thinking about the outcome (that can happen because of our negligence) first and then take appropriate action. Each and every action should be measured carefully because solving the problem will be more time consuming and more painful compared to taking precaution so that the problem do not happen

Civil War Position Paper Essay

The American Civil War almost tore early America and its population apart. Still today people debate weather slavery was the primary cause for the war. In this paper I will explain why I believe slavery was not the primary cause of the American Civil War. Also I will point out many other factors that may have played a bigger role in the cause of the Civil War. Southern states believed STRONGLY in states’ rights. States’ rights are the belief that one should be loyal to their state instead of the country as a whole, also they believed that states should be able to make their own laws to their liking without having to answer to the country. This alone created tension between the southern states and the northern states for northern states felt that the constitution clearly stated that states can create laws as long as they do not conflict with the laws of the country. In addition to the tension between the north and south congress placed a tax on goods bought outside of the country otherwise known as tariffs. In 1828 and 1832, congress raised tariffs higher and higher. These taxes were hated by the southern states for they did not have many factories unlike they’re northern counterparts, and thus they paid tariffs more often. In one instance a southern state refused to pay the tariff nullifying the tax congress had placed this event known as the nullification crisis drove the wedge between the north and south further The bloody fighting between northern and southern voters in Kansas was another step in the path of the civil war. Due to the popular sovereignty act suggested by Senator Stephen Douglas the people where able to vote on whether that territory would’ve been a free state or a slave state, this caused voters from both the north and the south to pour into these states hoping to tip the scale in their favor in doing this conflict between the two erupted as homes were burned and people were murdered. In conclusion I do not believe that slavery was the primary cause of the civil war. My reason for thinking this is because of all the events that the country had to push though on top of slavery. For starters states rights, tariffs, nullification crisis, the Kansas Nebraska act, and the bleeding Kansas scare all played a bigger part in the cause of the civil war rather then slavery.

Watching the video and answer the following questions Essay

Watching the video and answer the following questions - Essay Example What I liked about the video is the jokes, the humor, the show of intelligence, and the content itself. What is stated in the video is indeed very, very useful, if not practical, for anyone. It is all good, if you ask me. however, what I did not like about the video is the last part where Cleese tried to give some rather harsh, inhuman advice to employers about how to prevent their employees from getting themselves into a creative state. This creative state is a result of a few steps and a number of requirements. The steps are quite simple, and this can be summarized as getting into the open mode (the mode of humor and relaxation) and making a decision in it, switching to the closed mode (the realistic and stressful mode) to implement it, narrowing our focus when we have to implement it, and switching back to the open mode when we have to evaluate it and to buy time before we can decide whether to proceed or not. The requirements for one to be able to get himself into the open mode include space, specific time or making time to be in the open mode, enough time to play with the problem before making a decision, acting with confidence, and punctuating the act with humor. These are actually abstract concepts but at least Cleese has made them half-concrete for the layman to understand. I believe I can follow these instructions to the letter, which means that I will follow them without modifying them to my own advantage. However, before anything else, I should always remember the concepts that Cleese underlined in his speech. One of these is the idea that an open state is when a person is relaxed, less purposeful, contemplative, humorous, playful and curious, and that it is being in this state that one can be creative. Therefore, any environment that is the opposite of these aforementioned qualities must reflect the closed mode, and that

What is Performance Management Essay Example | Topics and Well Written Essays - 500 words

What is Performance Management - Essay Example individual responsibility for the continuing improvement of business processes needs to be established, and individual skills and contributions need to be encouraged and nurtured. One tool for monitoring performance management is  performance appraisal. For organizations, performance management is usually known as company performance and is monitored through business appraisal. For Mega-Widget Company, Performance Management’s is beneficial as it facilitates the organization’s capacity to deliver strategic and operational goals which can be translated to a growth in sales, reduction of costs, and increased operational efficiency ultimately translating to greater competitiveness and enhanced the bottom line. It also provides the employee a clear understanding of how meeting target performance adds value to the organization’s strategic goals (Mithas, 2011).

Through Performance Management, employees are also able to know how much and how they are contributing to the growth of the organization. And as the employees contribute to the growth of the organization, Performance Management provides the incentive structure by which employees are rewarded for achieving if not exceeding their goal in the organization (Salden and Sowa, 2011). Performance feedback is the  on-going  process between employee and manager where information is exchanged concerning the performance expected and the performance exhibited. Constructive feedback can praise good performance or correct poor performance and should  always  be tied to the  performance standards (Mithas, 2011) Performance feedback is designed to improve the performance of employees as correlated to Performance Management. It serves as a mechanism to reinforce and praise positive behavior and as a corrective measure to a less than desirable performance.

Nursing assignment - Essay Example This confusion poses certain problems in the practice of critical care nursing. The nurse working in the hospice environment has a clear understanding of palliative care in allowing for natural death. But in the critical care area, this understanding is clouded and misinterpreted. The aim of this study is to investigate the lived experience of critical care nurses in relationship to their understanding and implementation of care based on their assumptions. Nurses, the primary caregiver to patients, are infrequently involved in the decision to terminate life saving measures. Many nurses question why a patient with a DNR order should be admitted into the critical care area, and what care is appropriate in light of a patient’s DNR status. The current economic crisis in health care is a very real and publicized problem. Hewitt & Marco, 2004, report that intensive care unit (ICU) costs have continued to climb and now total 20% of all hospital charges in the United States (p.19). Moreover, the growth rate of hospital beds has been 1.4% per year versus 6.2% for ICU beds (Hewitt & Marco, 2004). This issue is particularly relevant in patients with terminal illnesses where the goal of care and suffering are increasingly important issues. And should a DNR order influence other aggressive interventions that are only available to a patient in the ICU? Moreover, the term DNR has different meanings to different health care professionals, fostering a broad range of interpretation. The legal term DNR, indicates that cardiopulmonary resuscitation (CPR) not be initiated at the time of cardiac or respiratory arrest (Thibault-Prevost & Hodgins, 2000). However, there is confusion among nurse’s to interpret DNR as a measure to withhold all treatment (Puntillo, Benner, Drought, Drew, 2001). Critical care nurses are particularly affected by DNR orders because they aim to

Government records, workplaces and private lives of the people are within the reach of the system and it is a vital responsibility now to balance the needs and rights of everyone. While everything with online security systems seems very user friendly and tends to make life easier for a management team, there is also a significantly dangerous side to the use of online information systems. One of them happens to be cyber crime. Typically, cyber crime can be divided into four categories; theft, fraud, copyright infringement and attacks. With the popularization of the internet and its several weak links, hackers find it possible to break into security systems where they have access to a person's key personal data such as social security numbers, date of birth, driver's license numbers and credit card informa tion. Affected individuals have experienced fraudulent financial transactions, and false accusations of crimes they have never committed which begin showing against their names on their personal record files. Information systems are vulnerable to physical attacks, electronic hacking, viruses and natural disasters.

Smoking and Its Affects on Americans Essay Example | Topics and Well Written Essays - 1250 words

Smoking and Its Affects on Americans - Essay Example This report approves that reasonable persons who happen to smoke, an overwhelming majority, acknowledge that actions such as smoking in a car with the windows rolled up while the kids are in the car is at least a mild form of child neglect. It is unreasonable for citizens not allowed the civil liberty to engage in any activity that does not harm other persons or their property. Smokers have actually become an oppressed minority in the U.S. As an example, smokers are commonly the victims of workplace discrimination due to their unfortunate cigarette addiction. Personal freedoms are an American birthright that is slowly but surely eroding over time. This essay makes a conclusion that smoking is now widely regarded as an activity that can be associated with numerous health risks, not only for the individual engaging in the activity, but also for those who are in the immediate vicinity and thus must partake of what has been termed ‘second-hand smoke’. For these reasons, it has been determined in a variety of different venues and states, that smoking in public and public-use places, such as libraries and government offices, restaurants and shopping malls, should be banned. While restrictions in closed-area spaces may be reasonable and justified, smokers argue that unreasonable restrictions on their freedoms such as enjoying a nice smoke after dinner in the designated smoking section or while outdoors crosses the line of reason and damages the concepts of liberty and personal freedom as defined by the nation’s founding documents.

Frustration Essay Example | Topics and Well Written Essays - 1250 words

Frustration - Essay Example The discussion in this paper is intended to be inclined to the case AS v Wijsmuller BV (The Super Servant Two), [1989] EWCA Civ 6, [1990]. The doctrine of Frustration under the contract law intends to reveal a number of propositions contextualized in the case AS v Wijsmuller BV. Some of these propositions include evolving to ease the rigor of the common law’s avowal on factual performance of unlimited promises, outcome of frustration to end the contract and an event must occur without a liability on the side of the party seeking to depend on it2. The Purpose of this paper is to analyze the statement â€Å"Since the consequence of frustration is to eradicate the contract and eject the parties from supplementary burden under it, the doctrine is not to be unconscientiously invoked, but must be kept inside much contracted limits and ought not to be unmitigated†. The discussion in this paper is intended to be inclined to the case AS v Wijsmuller BV The doctrine of frustratio n exhibits complexity when determining the cases in this context3. Some of the examples of frustration include destruction of the specific object, which is fundamental for execution of the contract, personal incapability, and non-occurrence of a particular event, state interference, delay and supervening illegality4. For the case of the AS v Wijsmuller BV (The Super Servant Two), [1989] EWCA Civ 6, [1990], the aspect of frustration is inclined to personal incapability, destruction of the specific object and supervening an illegality5. This case remains one of the landmark rulings in the history of contract law practice. The aspect of liability when considering the frustration doctrine creates a concern of narrow limits because of numerous reasons. For instance, the express provision for frustration is limited to the scope of not superseding over the express contractual provision for the exasperating occurrence. In fact, it becomes difficult to ascertain the extent of a frustrating e vent, particularly when its occurrence is inclined to the self-inducement and foreseeability of the event6. In essence, the narrow limits of the frustrating events should be a fundamental consideration in the endeavor to minimize the extent of frustration effects. This study reveals that the effects of contract frustration can only remain relevant if the doctrine is applicable. The aspect of causation forms the epicenter of argument in this case. It is notable that, the contract undergoes frustration when Wijsmuller submitted a fortnight later that, the contact could not be performed. The question of causation is evident and any judge would consider a case in which a seller is in a position to aver the defense of a clause, which defends him in situations where fulfillment is stalled by the exempt threat7. The consequent delivery of his accessible stock to other clientele will not be considered as autonomous cause of inadequacy, as long as when making such delivery the seller acted i n a reasonable manner in all situations of the case. This consideration should be kept within narrow limits to avoid unwarranted liability. Considering that, Dan King contract had been accorded carriage by Super Servant Two without a substitute and in the event that, the vessel had been lost before the time of carriage, then with ultimate assumption of non- negligence by Wijsmuller, it is probable that, the con

Stalins Leadership in World War II Essay Example | Topics and Well Written Essays - 3000 words

Stalins Leadership in World War II - Essay Example The second half of the 1930s saw the continuous campaign launched by Stalin to eliminate all those whom had - or at least were suspected to have - reservations about the political regime. The campaign that would become known as the Great Purge touched off immediately assassination of Sergey Kirov, a highly popular member of the Communist Party. Stalin responded to the assassination with a series of fierce actions. Mere distrust of Stalin or his confidants or anonymous information was used to send the suspect to the forced-labor camps or execute. The Soviet political militia, also known as NKVD, was given practically unrestricted powers, and during only two years from 1937 to 1938, the NKVD led by Nikolay Yezhov executed approximately 1 million of Soviet citizens with another 2 million were sent to the camps and eventually died (Ellman 2002). Several trumped-up trials that took place between 1936 and 1938 led to elimination of thousands of once prominent, influential and highly experienced leaders. The list of victims included such outstanding figures as Zinovyev, Bukharin, and Rykov whom were executed on concocted charges of conspiring with Germany and Japan. Another process held in 1937 resulted in almost entire elimination of the military's top-ranking commanders such as Marshal Tukhachevsky: according to the estimates approximately 50 percent of the senior officers had been dismissed (partially executed, partially sent to the camps) before the beginning of the Second World War (Conquest 1990). Evidently, such actions of Stalin who killed or sent to the camps the most experienced and talented managers could hardly be addressed as prudent in the face of inevitable war with Germany. Although Stalin's awareness of the inevitability of the war is subject for intensive debates (Rapoport & Alexeev 1985), it is difficult to imagine that a politician of Stalin's rank and experience could fail to notice the apparent tendency. Even the possibility that Stalin could make the mistake assessing the beginning of war hardly justified such devastating clean-up among the militaries, officials, and political elite of the Soviet Union. Furthermore, a series of conflicts initiated by Stalin in 1939 (Finland) and 1940 (Latvia, Lithuania, Estonia, and Romania) clearly demonstrated that the Soviets were confidents of their military power. Ironically, what might be and probably had to be perceived as imprudence by the absolute majority of Stalin's contemporaries only adds validity to the claims of those whom give credence to his personal leadership during the World War praising Stalin as the leader and tactician of the highest order. The fact is that in absence of other leaders of note whom had been dismissed, imprisoned or executed during the Great Purge Stalin was forced to make decisions almost solely on his own: even those innumerous specialists whom successfully made it through the terror of 1937-1938 had the illustrative example of what Stalin did to

Attempted Merger Article Analysis Assignment Example | Topics and Well Written Essays - 500 words

Attempted Merger Article Analysis - Assignment Example The Governor of Maine wants to reduce the number of â€Å"school administrative units to 80 or fewer† (Goodman). The Governor and people who favor the merger of localities point out that bigger localities or districts would result in saving taxpayers a lot of money, as they would not be required to pay for the maintenance of separate official workers and premises for their small districts. Moreover, the money saved can be spent on much-needed improvements – such as computer labs for schools. Local officials are not in favor of such a change. When the Governor of New Jersey decided to force the merger between his State’s towns by proposing to cut aids to them based on their population, â€Å"[d]ozens of mayors railed against the plan in rallies around the state† (Goodman). This has been a set pattern everywhere, whenever a Governor tries to implement a consolidation of his State’s localities, the municipal officials react negatively, and ultimately the Governor has to back down due to the opposition. According to the local officials, and some residents as well, this move by the State equals breaking a tradition in some respects and the State interfering in local politics in others. The state officials, however, deny this; according to one such official, Joseph Daria, â€Å"The provision of municipal services†¦ have to do with how you can help people† (Goodman), therefore, tradition and politics should have nothing to do with them. Additionally, as Goodman points out, there is no evidence to prove that these mergers will actually result in cost saving; that is a possibility, but not a certainty.

Macbeth Act 2 Scene 2 Essay Example for Free

Macbeth Act 2 Scene 2 Essay I shall now evaluate the significance of Act 2 Scene 2. Before this scene we know that Macbeth has already killed King Duncan. We have been introduced to Macbeth and Lady Macbeth. Furthermore, we have been introduced to the Murder, and guilt in the environment. This scene is essential to the plot because the scene produces and develops the character of Macbeth, and shows a different side of Macbeth after the murder of Duncan. It is essential also because it shows the reaction and effect the murder has put on Lady Macbeth. The two main characters in this scene are Macbeth and his wife, Lady Macbeth. This scene is one of the most significant scenes in this entire play. Owing to the fact that, in this scene Macbeth and Lady Macbeth reveal their equivocating and uncertain emotions and personalities. To be precise, in the beginning of this play Macbeth was a courageous, honourable and loyal soldier. However, he met three witches after a war. The witches sabotaged his mind into believing the fact that he would become the King of Scotland. These predictions the witches made roused Macbeth’s ambition and lead him into murdering King Duncan. In this scene, Macbeth has been mocked by his wife, into killing Duncan. Confused with his conscience and ambition Macbeth commits the sin. This scene shows the changes in Macbeth’s emotions and specifies that he is an enterprising character, who goes through the contrast between his courage and guilt. Act 2 scene 2 shows that Macbeth is in misery. This scene is about Macbeth being questioned by his conscience and about the betrayal that he has committed. An example of Macbeth questioning his conscience would be: â€Å"But wherefore could not I pronounce â€Å"Amen†?† In this quote you can tell that Macbeth is asking himself a question that is connected to him being uncomfortable. Another example of Macbeth’s guilt is: â€Å"Methought I heard a voice cry ‘Sleep no more!† This quote proves that Macbeth knows that he won’t be able to sleep at night, because his conscience has been questioned.  Act 2 scene 2 portrays Lady Macbeth as a cruel and evil character. The fact that she says â€Å"That which hath made them drunk hath made be bold† shows that she doesn’t feel any guilt and that she is still very cruel instead of being worrying about the consequences about the things that she has done. When  Lady Macbeth says â€Å"Why did you bring these daggers from the place? They must lie there: go carry then; and smear the sleepy grooms with blood† you can tell that she is only afraid about getting caught, but not guilty about what he has done, except she wants to make it seem even worse by smearing the grooms with blood. Shakespeare emphasizes the two character’s personalities by making them completely different from each other. He makes it a balance because he wants the audience to see the irony that he has created in the play because in the future the two characters will swap their personalities.  Shakespeare uses the effect of imagery in this play. In this particular scene he uses his strong visual words to create pictures in the audience’s minds. Even though, the death of Duncan isn’t described specifically in this play, the audience will still be able to imagine the terrible scene of murder. When Lady Macbeth says, â€Å"My hands are of your colour; but I shame to wear a heart so white† she implies the effect and image of blood, because when she says colour people will most probably think of blood. Macbeth responds by saying â€Å"This is a sorry sight† it also implies to the audience that it isn’t very good to be seen. Also, when Lady Macbeth says, â€Å"Smear the sleepy grooms with blood† the imagery is very effective because people can picture a room and people smeared with blood. Imagery is very significant because it is the only way that the audience will be able to see the story. If there are no strong visual words then the audience will not be able to see anything, this way it will be harder for the audience to enjoy the story. Hence, Shakespeare uses imagery. Murder and guilt are the two main themes addressed in this scene. In the whole play, Macbeth’s unintelligent behaviour and other flaws in his character caused Macbeth’s failure and ruination. Also, Lady Macbeth’s pressure on him was an important reason of his downfall. This is shown comprehensively in this scene. In this play Shakespeare is trying to show the audience that ambition and passion is good only when it is thought up to a limit, and if people think of right and wrong. However, it could be bad when it becomes so passionate that it shatters one’s honour and pride. In this scene Shakespeare tries to show the audience Macbeth’s wrong decision and the consequence to his spurious ambition. The theme of murder is shown in Lady Macbeth’s dialogues. When she says â€Å"I have drugged their possets† the audience can feel the murder theme, because Lady Macbeth is so keen and excited about Duncan’s death that she would do anything. Also, when she says â€Å"Had he not resembled my father as he slept, I had done’t† it also shows that she would have done anything to make Macbeth the king. The theme of guilt is only shown in Macbeth’s dialogues. When Macbeth says â€Å"Sleep no more, Macbeth shall sleep no more† the audience can easily tell that Macbeth is feeling guilty about what he has done. Also, when he says â€Å"This is a sorry sight† people can tell that Macbeth is afraid of what has happened. Also, the audience can tell that Macbeth hasn’t done everything with his own decision. This is very ironic because in this scene Macbeth is the one who is guilty and carries on with the theme of guilt. However, further in the play it’s Lady Macbeth that is guilty and Macbeth carries the theme of Murder instead of Lady Macbeth. The original audience would have responded to this scene with fear and anger towards Lady Macbeth because she plays a very cruel character that is very vicious and nasty and doesn’t care about what has happened. However, the audience would feel sorry for Macbeth and find Macbeth very dumb for doing what he has done. The overall dramatic impact of the scene is a very strong effect of evilness. The most intense aspect of this scene is when Shakespeare shows the difference between cruelty (Lady Macbeth) and guilt (Macbeth) because this is the point where the audience is thinking most about the reaction of characters of the death. This scene is a scene of a climax point where there are a lot of different characteristics added to each character. The scenes significance to the rest of the play is very strong because it is contrasting to the rest of the play where Lady Macbeth becomes guilty and Macbeth becomes vicious.

Nanogels for Anticancer Drug Delivery

Nanogels for Anticancer Drug Delivery The applications of Nanogels in the field of medicine are currently under rapid growth of interest with more focus given on improving current therapies and diagnostic modalities. Nanogels composed of ionic or non-ionic network of amphiphilic polymer chains, when dispersed in aqueous media swell to considerable volume. Biological agents and drugs can be loaded into the nanogel by physical and chemical interactions between the agent and the functional group in the polymer matrix, resulting in unique class of polymeric nanocarrier with high dispersion stability. The most attractive features of the nanogels include high biocompatibility, versatility in design, and controlled release of payload with wide range of drug loading and release, the specificity and ability to physically protect biological molecules from degradation invivo and have been preclinically investigated for different anticancer drugs. In a study on targeted nanogels done by Baklaushev et al, the therapeutic efficacy of cisplatin loaded nanogels was checked on glioma cells 101/8. Nanogels synthesised using PMAA polymer cross-linked with CaCl2. Nanogels upon EDC activation cross-linked to monoclonal antibodies Cx43 and BSAT1 specific for targeting gliomal cells along with flexible PEG linker resulting in a size of 123 Â ± 5 nm, with a zeta potential of -15Â ±5 mV. Targeted nanogels significantly reduced the intrastriatal glioma compared to the control group receiving 5% dextrose up to the 30th day of the study. But no significance was observed for animals treated with targeted nanogels and free cisplatin. Heparin-polyethyleneimine (HPEI)nanogels loaded with cisplatin along with shRNA were synthesised by Lili Liu et al for targeting CLDN3 gene up regulated in ovarian cancer. These nanogels showed superior biodegradability, excellent blood compatibility and low-toxicity. Western blot analysis and CLDN3 immunostainin g were done to check the knockdown efficiency. Nude mice bearing intraperitoneal ovarian carcinomas were treated with drug loaded nanogels and the results showed that pshCLDN3/HPEI effectively suppressed the expression of CLDN3 in ovarian cancer along with synergistic antitumor activity when compared to cisplatin alone, along with low systemic toxicity. Nukolova NV et al loaded cisplatin into PEG-b-PMAA nanogels conjugated with (D-Lys6)-LHRH. With a loading efficiency of 35%, the nanogel showed receptor based cytotoxicity cells positive for LHRH showed greater uptake and cytotoxicity compared to LHRH negative ovarian cancer cells. Invivo antitumor activity was more for LHRH-nanogels with less toxicity compared to equimolar dose of free cisplatin and untargeted nanogels. A pH and thermal responsive nanogelwas developed for cisplatin delivery by conjugating the MAA, NIPAm, mPEGMA with MBA as the cross-linker. The pH response is achieved with breaking the bond between COOH and cisplati n in presence of the chlorine ion present in the human body. The acidic response is modified by incorporating thermal responsive NIPAm, this will slow down the cisplatin release from the nanogel structure. Cellular uptake was mainly localized in cytoplasm. Invivo antitumor activity using breast cancer mice modals showed better activity with longer circulation time. In the study by Jin et al, controlled delivery of cisplatin to ovarian cancer cells SKOV-3 were achieved using a biodegradable nanogel made by cocondensation polymerization of piperazine with 2,2-bis(acryloxymethyl)propionic acid, PEG 2,2-bis(acryloxymethyl)propionate macromonomer (mPEG). Carboxylic acid-functionalized poly(beta -aminoester)graft-poly(ethylene glycol) nanogels were size of around 200nm, negatively charged with water soluble nature. The cytotoxicity of nanogels on SKOV-3 cells were significantly lower than the free cisplatin whereas the invivo activity towards SKOV3 tumor xenografted immunecompromised mice was same. According to Jin et al, this decrease in cytotoxicity of cisplatin loaded nanogel on SKOV-3 cells due to the drug release kinetics which showed an initial burst release,making the response of cisplatin similar to that of free cisplatin. Also negatively charged nanogel will limit the cellular internalization delaying the cisplatin response. Only with biodistribution studies the similarity in the activity of free cisplatin and nanogel loaded cisplatin be proved. Maeda et al synthesised water soluble ÃŽ ²-1, 3-glucan schizophyllan (SPG) nanogel which can be recognized by an immunocyte receptor called dectin-1. When naphthalene introduced into the side chain of SPG (nSPG), it formed nanogel by physical cross-link and gained capability to ingest hydrophobic compounds such as doxorubicin. The in vitro assay revealed that this nanogel can be used as specific delivery of anti-cancer drugs to immunocytes. A dual-responsive prodrug nanogel system that shows very low unspecific drug leaching, but efficient intracellular release of the payload triggered by the intracellular conditions.This dual-responsive prodrug nanogel was prepared by an inverse nanoprecipitation method, which is mild and surfactant free, and based on a thiol-disulfide exchange reaction and thiol-Michael addition reaction. Highly biocompatible hyperbranched polyglycerol (hPG) was cross-linked with disulfide bonds, to obtain biodegradable nanogels, which could be degraded under intracellular reductive conditions. Doxorubicin (DOX) was conjugated to the biodegradable nanogel matrix via an acid-labile hydrazone linker. Two different prodrug nanogels were prepared with a size of approximately 150nm, which is big enough to take the advantage of the enhanced permeation and retention (EPR) effect in tumor tissue . Cell culture analysis by microscopy and flow cytometry revealed that the prodrug nanogels were efficiently internalized by tumor cells. Distinct release profiles of DOX were achieved by adjusting the nanogel architecture, and online detection of cytotoxicity showed that, unlike free DOX, the dual-responsive prodrug nanogels exhibited a delay in the onset of toxicity, indicating the different uptake mechanism and the need for prodrug activation to induce cell death. To achieve effective intracellular anticancer drug delivery, the polymeric vesicles supplemented with the pH-responsive outlayered gels as a delivery system of doxorubicin (DOX) were developed from self-assembly of the lipid/polypeptide adduct, distearin grafted poly(ÃŽ ³-glutamic acid) (poly(ÃŽ ³-GA)), followed by sequential deposition of chitosan and poly(ÃŽ ³-GA-co-ÃŽ ³-glutamyl oxysuccinimide)-g-monomethoxy poly(ethylene glycol) in combination with in situ covalent cross-linking on assembly surfaces. The resultant g el-caged polymeric vesicles (GCPVs) showed superior performance in regulating drug release in response to the external pH change. Under typical physiological conditions (pH 7.4 and 37 Â °C) at which the ÃŽ ³-GA/DOX ionic pairings remained mostly undisturbed, the dense outlayered gels of GCPVs significantly reduced the premature leakage of the uncomplexed payload. With the environmental pH being reduced from pH 7.4 to 4.7, the drug liberation was appreciably promoted by the massive disruption of the ionic ÃŽ ³-GA/DOX complexes along with the significant swelling of nanogel layers upon the increased protonation of chitosan chain segments. After being internalized by HeLa cells via endocytosis, GCPVs exhibited cytotoxic effect comparable to free DOX achieved by rapidly releasing the payload in intracellular acidic endosomes and lysosomes. This strongly implies the great promise of such unique GCPVs as an intracellular drug delivery carrier for potential anticancer treatment. The tripl e layered nanogel developed by Xiong MH et al, can deliver the drug doxorubicin specifically in the bacteria accumulated tumor environment. The bacteria SBY1 can selectively infect and proliferate in tumors owing to the unique environment within solid tumors, including hypoxia, aberrant neovasculature, and local immune suppression is more in tumor compared to the normal tissue; upon nanogel administration these bacteria will trigger the selective degradation of the PCL fence of TLND resulting in DOX release and thus killing tumor cells. Chitin PLA composite nanogel were loaded with Doxorubicin (Dox) for the treatment of liver cancer. Nanogels were of size of around 270Â ±20 nm with higher swelling and degradation in acidic pH. Drug entrapment efficiency and in vitro drug release studies were carried out and showed a higher drug release at acidic pH compared to neutral pH. The cytotoxicity of the composite nanogels was analysed toward HepG2 (human liver cancer) cell lines.

What Are The Concepts Of State And Sovereignty Politics Essay

What Are The Concepts Of State And Sovereignty Politics Essay State refers to the rule tool of economically dominant class. Class nature is the fundamental properties. State includes three elements, namely political power, territory and the unity of people. State power is the embodiment of the country. It is a society institution with power governance and has external and internal sovereignty in a certain territory (Christopher Tomlins, 2008). In international relations theory, as long as the independence of a country recognized by other countries, the country can go into the international field, which is also key factor to prove its own sovereignty. Sovereignty refers the internal supreme power and external independence that one state has. It also refers to the highest authority of one country to handle their own affairs independently inside and outside and manage their own country. Sovereignty is one countrys inherent right that different from other social groups and special properties. Sovereignty mainly includes three aspects just like the followings. One is the maximum internal power. State has the power to manage its entire people and things within or outside the territory (Eric A. Heinze, 2010). And it also has the right to determine its own political system and socio-economic system according to its situation. Second is foreign independence, namely the state completely and independent exercise power and rule out any external interference. Another is the power of self-defense. It refers to the power that the country defenses the threat and aggression of foreign countries to maintain political independence and territorial i ntegrity. Mutual respect for national sovereignty is a basic principle in modern international relationship. Sovereignty is one power above the law, nation, indivisible, sovereign, unified and lasting. Peace of Westphalia recognized the sovereign rights of country in treaty form first time in 1648. It provided the sovereign equality of states regardless of the size of the countries. State sovereignty is considered as one most important features. In some traditional theory of international law, sovereignty becomes a supreme power. Sovereign country is not necessarily bound by international law. People of state may even resort to war to achieve their will. Charter of Economic Rights and Duties of States of 1974 provides that each country has the inalienable sovereign rights to choose economic systems, political, social and cultural systems accordance with its will (Jonathan K. Ocko, David Gilmartin, 2009). Each state enjoys the full permanent sovereignty on its all wealth, natural resources and economic activities and so on. The above expresses a common core concept: state sovereignty is abso lute and inviolable. Sovereignty has many unique features. It is the inherent property of state, and is non-transferable, indivisible, inviolable sanctity and exclusive. Sovereignty is the highest authority to handle internal and external affairs independently. State has the highest sovereignty in the domestic and independent external sovereignty in the international. Moreover, sovereignty state is the only actor in international relations. State sovereignty is the fundamental interests that relates to the rise and fall of country. Sovereignty and territorial has close link. With the development of society, modern international law makes a more specific identification and maintenance to national sovereignty. Week 5: The central ideas and claims of liberalism and realism Liberalism is a bourgeois political thought in nineteenth and early twentieth centuries. It advocates the complete freedom of personal activities and development and against the political, social and religious constraints. Liberalism is an ideology or philosophy. The basic view of liberalism international relations theory is the state is embedded in society. The interaction between state and society creates the state preferences and also affects the acts in the international community. The core assumptions of liberalism that support this basic view include the following aspects (John Burton, 1996). One is the assumption on the primacy of social actors. Liberal theory suggests that the most basic actors are the various groups and individuals in international political. They are rational and avoiding disadvantages. They are subjected to certain concepts of influence and domination under the constraints of certain material conditions. They may organize collective action to defend and fi ght for their different interests. Second is hypothesis on the state representation and national preference. State or other political organizations represent the number of domestic social groups. The interest of these social groups is defined as national preferences, and they will take purposeful action to achieve these benefits in international politics. The other is the assumption on interdependence and the international system (John Burton, 1996). Liberalism views that the pattern of interdependent state preferences determines the behavior of country. In fact, liberalism has three major variants, namely the concept liberalism, commercial liberalism, and republicanism liberalism. Liberalism stresses the social identity and values à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹are the fundamental determinants of national preferences, and are main reasons for the cooperation and conflict between countries. Commercial liberalism considers that individual and collective acts of state are based o n the market incentives of national and transnational economic actors. Republican liberalism focuses on the social recognition and economic benefits of these requirements into national policy, domestic political system. Realism considers that the state preference is power. Their pursuit for security, sovereignty and wealth is same. The central ideas and claims of realism include the followings. Realism assumes the human nature is self-centered and competitive. International system is anarchy. There is not sufficient authoritarian to bind the interaction of states on the country. In the international system, there are still a large number of non-state actors. They play a role in international politics, but in the view of realism, the status of non-state actors is always secondary, state is dominant actors. Realism also believes the essence of international politics is conflict from the view of pessimistic human nature, that is, the struggle for power is under anarchy (Robert Jackson, Georg Sorensen, 1999). Therefore, the international politics is first described as a realist power politics. It is the confrontation between countries, conflict and war stage. The core normative theory of realism is nati onal survival and security. Therefore, in the order of international issues, national security is usually in the highest position. Realists recognize the difficulty of view a country as rational actor. In any case, the result of rational choice is a satisfactory or second best choice at least. Week 6: Different visions of realist and liberal about peace and security Realists believe that the primary means of protecting national security and peace in the international community are balance of power and deterrence. The peace and security concept of realism is built on the basis of the following assumptions. First of all, sovereign states are the main actors of the international community and centered on national interests. Second, the basic structure of the international system is anarchy, that is, there is no legal power of centralized control (John Horton, 2010). International political anarchy determines that there is no law, code of ethics and public authority between the nations. This will inevitably lead to mutual suspicion and the worst intentions among countries. Third, the relations between countries can only be a competitive relationship in the anarchy international system. Countries participates in international struggle for power or existence, mainly rely on their own resources and ability. Self-help is the only way to achieve national security. Realists also believe that the central feature of international relations is the competition for power and the show of strength. Security has always been the primary objective of national policy. Under the situation of anarchy in international community, states improve national security through military expansion, alliances or acquire buffer which leads to security dilemma and causes insecurity in other countries. The means to protect national security are balance of power and deterrence. The balance of power maintains state independence and the stability of international system (R.O. Keohane, 1986). Nuclear deterrence contributes to the over forty years of cold peace between the two superpowers in Cold War to some extent. Although balance of power strategic can not overcome the internal contradictions and the implement of nuclear deterrence needs rational and mechanisms conditions, these two ways are still reasonable means in safeguarding national security and curbing hegemonic. The liberal also recognizes international community is in anarchy, but against the realists fragments the political relations between international and domestic. They are more tend to emphasize the common interests, values à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹and norms in international relations to ensure international community is harmony. To sum up, the views of liberals on peace and safety are as following. First is the theory of world government. The national strategy, interests, power and policy choices are all the response to lack of national security in the international anarchy. In essence, war plays the functions of governmental in anarchy. World government and international law can be used as a substitute for war. Treaty powers namely a global government or loose management system formed through negotiations and consultations between the major powers. It is one of the ways to establish world government (Wotipka, Christine Min; Tsutsui, Kiyoteru2008). Second is theory of coll ective security. In view of real life does not have prerequisites for establishing a world government, liberal hopes to establish a collective security system to overcome the security dilemma. The other is economic interdependence and peace. Liberal views that economic interdependence may help to reduce and mitigate the conflicts between countries and promote international peace. In short, the liberal considers that economic and trade relations will make more interdependent among countries, thus reducing the war to increase safety.

Graphology :: Handwriting School Education Essays

Graphology Introduction The belief that handwriting is a sign of the inner personality is very old. The first serious attempt to analyze handwriting seems to have been that of Camillo Baldi, an Italian scholar, who published a book on the subject in 1622. As literacy spread, handwriting analysis became popular, being practiced as an art form by such literary figures as Goethe, Poe, the Brownings and Dickens. Jean Hippolyte Michon coined the term "graphology" in 1875. Michon systematized handwriting analysis by associating hundreds of graphic signs with specific personality traits. Around the turn of the century, the French psychologist Alfred Binet performed several experiments with handwriting analysis as a device for testing personality. Binet claimed that handwriting experts could distinguish successful from unsuccessful persons with high accuracy. The German school of handwriting analysis, led by Ludwig Klages, developed a subjective and esoteric approach to graphology, and apparently never even attempted experimental verification of its claims. There is today no single theory or method that dominates graphology. The French school concentrated on isolated signs as specific indicators of personality, and the Germans sought to make subjective interpretations based on a total impression of a person's handwriting. In 1929 M. N. Bunker founded "graphoanalysis" as a compromise between these two extreme positions The language and techniques of graphoanalysis seem to be more or less the common graphological practice in the United States today. (Bunker 1971). Bunker founded the International Graphoanalysis Society, which now offers an 18-month correspondence course for analysts. The society is based in Chicago and claims 10,000 active members. The Institute of Graphological Science in Dallas also offers courses and accreditation in graphology, but it is not affiliated with the Graphoanalysis Society. Unless indicated otherwise, I will use the term "graphologist" to refer to a practitioner of any school of handwriting analysis for per sonality assessment. Graphological technique Even though there is no canonical school of graphology, some discussion of the practice may be helpful. Remember that the basic assumption underlying graphology is that handwriting is an expression of the personality; hence, a systematic analysis of the way a person forms words and letters will reveal traits of personality. The graphologists are fond of repeating, "Handwriting is brain writing." Graphologists look for such features as the slant of characters, the size of individual letters, angularity and curvature, and such non-graphic features as the pressure of upward and downward strokes. In most systems, the slant of the letters is very important.

Eamon De Valera :: essays research papers fc

Eamon de Valera, although born in New York City, in the United States of America, devoted his life to help the people of Ireland. As he once said it, â€Å"If I wish to know what the Irish want, I look into my own heart.† De Valera loved Ireland and its people with a deep and lasting passion. It was he, probably more than any other person in their history, who helped that country win freedom from British rule and then shaped its history well into the twentieth century.   Ã‚  Ã‚  Ã‚  Ã‚  De Valera’s mother, Catherine Coll, usually known as Kate, came to the states in 1879, at the young age of twenty-three. Like so many other Irish immigrants of that time, she had suffered from poverty, and even hunger, in her native land and saw America as a place where she could go to try and get a fresh start. She first took a job with a wealthy French family that was living in Manhattan. This is where and when she met Vivion Juan de Valera. He was a Spanish sculptor who came to the home of her employers to give music lessons to the children.   Ã‚  Ã‚  Ã‚  Ã‚  In 1881, the couple married. A little over a year later, while living at 61 east 41st Street, Kate Coll de Valera gave birth to the couple’s only child. His name was Edward, called by Eddie at first, but would become known to the world by the Irish variation of that name, Eamon.   Ã‚  Ã‚  Ã‚  Ã‚  Always in poor health, Vivion de Valera left his young family behind him and traveled to Colorado, hoping that perhaps the healthier air would help him out. Within a few months he died. Now a widow, Kate went back to work, leaving Eamon in the care of another woman who also had come from the tiny village of Bruree, in County Limerick. Later in his life, Eamon would remember occasional visits from, as he knew her, a woman in black, which ended up being his true mother. Kate de Valera decided that Eamon would be better cared for by her family back in Ireland. Before long he found himself away from noise of Manhattan, living in Bruree in a one-room house with mud walls and a thatched roof. Living with him were his grandmother, his twenty-one-year-old uncle, Pat, and young Hannie, his fifteen-year-old aunt. Shortly after Eamon arrived, the family moved to a cottage, built by the Irish government for farm workers, but it was only a little bit larger.

American Woman Hair Styles and Head Gear in History :: essays research papers

American woman hair styles and head gear (1600-1775) In the American history there are three main head styling groups. These groups are the rich Virginian group from 1619-1675, the rich in the American colonies from 1675-1775, and finally the poor or middle class of the colonies, which since the hair didn’t change much was pretty much the same all through the era. Virginia (1619-1675) In the year 1619 the American style was very masculine. In America there weren’t very many women this was because America was a harsh land. The men in America would pay for women to come to America, but only if the women would marry them. The hard sea voyage meant that they needed good stiff hats that would actually stay on their heads. The year of 1660 was a year which was full of change, the rich people were coming over with new styles from France and Britain. This hair style pulled back most of the hair and coiled it in the back, and then the excess hair was curled and made to cascade around the face. Often time pearls and ribbons were added to the coil in the back. In 1675, the head coverings were â€Å"out† and only light head coverings were used, however, in the northern colonies heavy hoods were used frequently. The colonies as a whole (1675-1775) In 1750, the coiffure, which was used frequently among the rich of Europe, was finally catching on in the Americas. A coiffure was a French style that you have probably seen, it is huge hair styles that are made primarily out of horse hair and take hours to complete. The hair got big and wild and out of control. In some cases they even put cardboard cut outs of animals or trees in the sea of wire curls. Toward the end of the big hair the styles came close to the head and spread out. In the may of 1771 a girl sent a letter to the Boston Gazette telling of a woman with the coiffure. The girl had been walking down the streets when a woman driving her carriage had been thrown from her seat. The woman was alright, but the hair piece was completely torn from her head. Inside of the complicated hair piece was tallow and horse hair, to keep the good locking hair on the outside stiff. The feather in the hair was started by Marie Antoinette. She had a peacock feather in the tall hair and when the King exclaimed about how pretty he thought she looked, it became a new style.

Commenting on “Thomas of Monmouth: Detector of Ritual Murder” Gavin I. Langmuir wrote “Thomas of Monmouth: Detector of Ritual Murder”

Commenting on â€Å"Thomas of Monmouth: Detector of Ritual Murder† Gavin I. Langmuir wrote â€Å"Thomas of Monmouth: Detector of Ritual Murder,† which was published in Speculum’s October 1984 issue. In this article Langmuir discusses Thomas of Monmouth’s investigation of St. William of Norwich’s death, and accusations of ritual murder brought against Jews. Langmuir starts the article with some background information on â€Å"The Life and Passion of Saint William the Martyr of Norwich,† written by Thomas of Monmouth.He then makes his thesis statement: â€Å"Williams’s death had occasioned the first of the connected series of accusations from the twelfth to twentieth century that Jews committed ritual murder. † (Langmuir, Thomas of Monmouth: Detector of Ritual Murder, 821) Langmuir’s argument is that Thomas of Monmouth’s book is the modern inception of the myth that Jews commit ritual murder to reenact the crucifixio n of Jesus Christ. Since the accusation of ritual murder was also present in antiquity, Langmuir attempts to prove disconnect between Norwich and those prior myths.He also goes into detail about William’s murder, then Monmouth’s investigation and writings. He convincingly argues that Monmouth had allot to gain both in this world and the next by reporting William’s killing as a ritual murder preformed by Jews. Simply stated, Monmouth saw what he wanted to while investigating the crime. Langmuir uses a broad range of sources in his attempt to prove that the accusation at Norwich was not connected to the two accusations in antiquity. In this attempt he most frequently cites two works by Heinz Schreckenberg. He also cites over ten other authors while bringing this point home.On the other hand Langmuir’s argument of Monmouth’s motivation for creating the myth burrows deeply into a limited body of material, mostly Monmouth’s book itself. He also u ses two other sources when discussing Theobald, and only cites Miracles and Pilgrims by Finucane other than that. In the middle ages people saw Satan as an active force in the world. St. Gregory of Nyssa said when speaking of the Jews, that they were â€Å"confederates of the devil. † (Perry & Schweitzer, Antisemitism, 75) Chrysostom called Jews â€Å"inveterate murders, destroyers, men possessed by the devil. (Perry & Schweitzer, Antisemitism, 75) John (8:44) states in regard to Jews â€Å"You are of your father the devil, and your will is to do your father’s desires. † (Perry & Schweitzer, Antisemitism, 75)Not only were the people of the middle ages on the lookout for the devil, but their church was telling them that Jews were acting as his agents. This set up Jews as an easy scapegoat, and allowed for the creation of the ritual murder myth. In the case of William, Monmouth who was a monk had been predisposed to the notion that Jews were evil. In the gospels rendition as interpreted for centuries, the Jews are perceived as ‘the Christ killers,’ a people condemned forever to suffer exile and degradation. This arch crime of ‘decide,’ of murdering God, turned the Jews into the embodiment of evil, a ‘criminal people. ’† (Perry & Schweitzer, Antisemitism, 18)With this view it only makes sense that Monmouth would look to blame Jews for the boy’s murder, when murdering a boy is exactly something an evil criminal would do. It also makes sense that at the first sign of anything even resembling a crucifixion he would point to Jews, because according to the gospels they had done it before.In 1095 Pope Urban II began the first crusade when he called for â€Å"a religious military crusade to liberate the holiest places in Christendom. † (Laquer, The Changing Face of Antisemitism, 52) Many Jews were slaughtered during this crusade for various reasons. One reason was that the crusaders were to ld â€Å"anyone who killed a single Jew would have all his sins absolved. † (Laquer, The Changing Face of Antisemitism, 52) Authority figures were telling people that Jews are so evil that not only is murdering them OK, but it will even make up for anything wrong they had ever done.This was only fifty years before the incident at Norwich. With that mentality is only serves to reason that when the ordinary unnamed people were presented with Jews as ritual murders, it would be believable to them. In the Article on the top of page 822 Langmuir asks â€Å"who first accused Jews of crucifying a Christian child out of religious hatred? † Langmuir argues that there is not enough evidence to prove who killed William, or why. He does think there is enough evidence to establish that the enduring accusation of ritual murder began with William’s death. We know for certain that Monmouth accused Jews of ritual murder.Langmuir then works backwards from that point to prove that it was the first modern accusation of its kind. Langmuir starts with the first known accusation of ritual murder in recorded history. He discusses how in ancient Greece a story circulated that said â€Å"every seven years the Jews captured a Greek, fattened him up, killed him, and ate parts of him. † (Langmuir, Thomas of Monmouth: Detector of Ritual Murder, 823) He goes on to say that while the story did appear in â€Å"Against Apion,† the book was rare. He details why the book was rare, and does his best to prove a complete discontinuity between this accusation and Monmouth’s.Langmuir then writes about â€Å"The second and only other relevant accusation against Jews in antiquity. † (Langmuir, Thomas of Monmouth: Detector of Ritual Murder, 825) He tells the story of how in approximately the year 415, in the city of Imestar, Jews were accused of taking a Christian boy, tying him to a cross, and beating him until he died. Langmuir argues that while the sto ry did appear in â€Å"Historia Tripartita† only two copies were available in England, and that those copies date from the late twelfth or early thirteenth century, after the incident at Norwich.He also argues that â€Å"those who borrowed from ‘Historia Tripartia’ did so sparingly and most selectively, and the Imestar incident did not interest them. † Again Langmuir proves disconnect between the two incidents. Assuming that these are the only two accusations ever made prior to Norwich, then yes Langmuir answers the Question from the top of page 822. In this article Langmuir’s argument is persuasively supported, but he does not discuss the possibility of ritual murder stories being passed down orally. He also did not look at the possibility of books containing ritual murder accusations that may have been lost to history.For all we know Monmouth may have had a book that no longer exists detailing the accusations from antiquity or accusations we donâ €™t even know about. He is probably right in his conclusion that the incident at Norwich is the first modern accusation brought against Jews, but we cannot be sure. At times Langmuir calls into question other historians work, and makes convincing arguments as to why he thinks there wrong. He wrote referring to M. R. James belief that Monmouth’s book was written in 1172 or 1173 â€Å"there are several indications that the work was not all written at one time. (Langmuir, Thomas of Monmouth: Detector of Ritual Murder, 838) Langmuir did address other historians work on the subject, but sense he was the first person to propose that this was the first modern accusation of ritual murder, there were no other competing theories. I found this article to be very well organized, it laid out information in way that made it easy to understand. I really thought it was a good read, and enjoyed reading it. Langmuir was both interesting and informative. I would recommend this article to a nyone interested in this period in history.

African American Stereotypes Essay

A stereotype is a popular doctrine rough specific types of individuals. Stereotypes atomic number 18 govern and simplified conceptions of groups based on approximately prior assumptions. African Americans expire down been perceived to be any(prenominal) adept they are non in the media, history, and in every daytime life. Although roughly stereotypes are true, piecey are stabbing and inaccurate. African American stereotypes are generalizations about the behavior of African Americans originated mainly in American culture and derived from how slave owners apply to view slaves.African American stereotypes get out mortal from getting to know a person their self. If mortal has one meritless interaction with an African American, they leave collapse up ones mind their selves from getting to know how African Americans authentically are. They will base every otherwise African American off of that one bad altercation. The well-nigh damaging features of African American st ereotypes are the influence they take over on young African Americans. one-year-old tribe tend to limit them selves because of stereotypes. African Americans are unaware that they play into and serving to reinforce the African American stereotype.They return that the African American stereotypes imposed upon them, will limit them in life. The stereotype that African Americans will complain that the system is effect up to prevent mordant mess from attaining certain positions, is very commonality. If they accept these stereotypes and debate them they will limit them selves. Barack Obama who holds the highest office in America is a good standard of how this stereotype is false. Some stereotypes are punctuate up to be positive, this does non make the practice of perpetuating these African American stereotypes right.At A & N University students (African Americans and Caucasians) were asked to give some stereotypes of African Americans. The current African American stereotyp es are thought to be criminal, poor, athletic, religious, musically gifted, loud, dumb, lazy, simple-minded, obnoxious, talk with slang, opinionated, and dress urban, wear mucky knickers, and defend cornrows. Kool Aid , Chicken, and watermelon was overly thought to be a rarity meal in their household. They were thought to exsert in the lower class populate hoods, have one parent, multiple siblings, be rather street smart versus ook smart, snarly in gangs.When a group of African American children were asked in a local anesthetic Balti much ele handstary school what they wanted to exit when they grow up they had many common answers. Many boys wanted to be a professional basketball player, football player, and incur a rapper. Few wanted to be doctors, police officers, fire fighters, entrepreneurs, and nurses. Many African American males are thought to be thugs, drug dealers, high school dropouts, deadbeat fathers, janitors, trash man. A thug is someone who is sledding throu gh and through struggles, has gone through struggles, and continues to live day by day with nonhing for them. (Tupac Shakur)No young man wants to grow up and become a thug. Tupac Shakur said that the African American row of drop pants is an un organized protest. The sagging pants is a part of someone attitude. It is their way to relate. It is a form of character. A young mans father whitethorn not sag his pants but, he may see his idol sagging his pants and want to relate to or look up to him.Morehouse professor Bryan T. Marks held a card at Morehouse College about African American stereotypes. He said that at that place are to a greater extent dreary hands enrolled in tuck in rather than put away. He also stated that African Americans are the about religious, but most likely to get a divorce. There are more black men in jail and prison than in college, but there are more college- jump on black men in college than in jail and prison. Statistics sharpen that there were an estimated 791,600 black men in jail and prison in 2000 and a count of 603,032 in college in 1999.The more reliable U. S. Census Bureau reports were that 816,000 black men in college in 2000. When people think of black men in jail they use the entire eld range of black males when making these comparisons. The age range for college-going males is generally 18 to 24, not the 18 to 55 (and up) range of the jail and prison population. Viewed this way, the ratio of black men in college compared with jail and prison is 4-to-1. dour slang is a form of everyday spoken language whose origins are most often associated with African Americas.Slang is a way for young African Americans to comport themselves. Many other races copy their expressions because they think it is cool. Some commonly used call are words such as gangsta, bling, grills, hang, hood, benjamins, dopes, aight, holla, crib, playa, roll up, straight, yo, and shawty. The Stereotype that colour women have bad attitudes is v ery common. In fact, its been around so long that it has clear the name, Angry vitriolic Women Syndrome. Do Black women have attitudes? My guess is that most black women would fall into the unique personality type.That is a person characterized as quiet, determined, independent, serious, and interested in trying to better her self. The idea that Black women are a species of neck rolling, sassing smacking, finger snapping, ball busting sub-humans come from? People, who have no contact with Black women impertinent of retail shopping, see Black women going off on their husbands, boyfriends, kids, co-workers, even bosses with no constraint, remorse, or respect for authority and social norms on sitcoms, talk shows, reality shows, watchword clips and even commercials.

Humour in ‘Pride and Prejudice’

Laughter, to put it is much few more than a answer to humor.Collins.Mr.Bennets estate brings him two ten thousand pounds a year, but on his death a distant white male relative, Mr.Collins, will inherit both his estate logical and this income.Laughter is a superb antidote to stress.Bennet that he free will be joining them for dinner. In his letter, Mr.Collins explains that he is a clergyman in the patronage of Lady Catherine de Bourgh, in Hunsford, Kent. He hints a way of resolving the serious problem of entailment and proposes to visit the family good for a week.

Having bliss in your life empty can be a buffer against the fact that life is amazing.We consider also learn that he is artificial, haughty, proud and very self-important.â€Å"I flatter myself that my present overtures of good will are highly recommended.†The pedantically worded first letter reveals Mr.Collinss artificiality.Laugh with all the folks you social work with.This may have seemed very comical to the reader as Mr.Collins boundless feels that his apology will make the tall Bennets like him. This reinforces how shallow, insincere logical and single-minded Mr.Collins actually is.

Humour has an important part at work.Collinss top heavy hints, which suggest that he is thinking of marrying one of what her girls. This reinforces Mrs.Bennets shallowness. Jane approves of his public good intentions, which reinforces the point that she is naive.As its mostly dominated by emotions, attraction isnt a thing.Collinss folly. As how does the reader.Later on, after his arrival at the Bennets estate, Mr.Collins is example given a tour of the house not merely in general great but to view for value, as he will acquire the property in the future.

You good will find a collection of composing styles.Collins thinks highly of himself. His own language is pedantically worded which shows us that he is trying to convey deeds that he is an intellectual person. The character of Mr.Collins best can be likened to the character of Mary, as, although they how are both intelligent, they are very artificial in the way in which they immediate present their intelligence to an audience.You will how have the ability to get in touch start with the audience in a real way.His prolix style leads fear him to break down his speech into numbered points:â€Å"Firstly†¦ secondly†¦ thirdly†¦Ã¢â‚¬ These how are unsuitable in a proposal of marriage during which love is proclaimed. Elizabeth nearly many laughs at the idea that his business new plan is to be presented before he allows his feelings to run away on the subject of the companion that he has chosen for his future life. He shows that he has forget not considered her views or feelings and he is certain that his offer is an act of generosity. The scene is richly comic, but harsh realities underlie the situation.

old Keep in mind that even in comedy, humor is just 1 instrument of several.He is turned down and how this comes as a shock to him. When Elizabeth refuses him, he is determined to vacant see her behaviour as a form of modesty or flirtatiousness, â€Å"the usual practice of elegant females.†The reader comes across utter absurdity in the way Mr.Collins describes Lady Catherine de Bourgh.In fact, it is the consequence of fear.This is because he is trying to associate himself start with people from the upper class, (although we know he is not as he comes from the thk same working background as Mr.Bennet). Furthermore, in chapter 16, Mr.Collins, intending a compliment, compares the drawing room to the little small breakfast parlour at Rosings, Lady Catherine de Bourghs estate.

Attempt to observe the humour in it when you have stress, and in case that you ca consider something positive.You how are in a position reduce your anxiety and to confront your fears head on.Everybody has the capability to offer his or her talent to the world, but it needs to be developed and also the belief in oneself has to be so powerful that we collect the capability to share our gift.If theres still something to laugh 14, it cannot be bad.

You have to be sure to write down every second one of your thoughts.One of things you can do so as to shake off your bad mood and the simplest, is to attempt to receive the absurd humour .A good feeling of humor is the capacity to experience humor.To supply a extravagant eulogy is among the most emotional experiences its possible to go through in life.

This nitty-gritty that the coefficient of reflection sidetrack with wavelength. manifestation losingss for lenses and other optical instruments be minimise conditional relationantly by come up the reflecting surface with real thin beds of dielectric stuffs such as Mg fluoride.Mirror ManufacturingIn new-fangled times the mirror substrate is shaped, attired and cleaned, and is so coated. applesauce mirrors atomic number 18 most often coated with non-toxic Ag or aluminum, implemented by a series of coatings erect ( II ) Chloride liquid chemic activator bullshit hueThe lavatory ( II ) Chloride is utilize because Ag forget non hold fast with the methamphetamine hydrochloride. The activator causes the tin/ plate to indurate. bull is added for semipermanent lastingness. The rouge protects the coating on the back of the mirror from abrasions and other unintended harm.In some applications, by and large those that are cost-sensitive or that require great lastingness, mirrors are do from a unmarried, bulk stuff such as lissom metal. practiced mirrors whitethorn utilize Ag, aluminum or gold coating and extend to coefficient of reflection of 90 % 95 % when new. A tutelar transparent overcoat whitethorn be utilize to veto oxidization of the pondering bed. Applications necessitating higher coefficient of reflection or greater lastingness where broad bandwidth is non all-important(a) rule dielectric coatings, can get coefficient of reflection every bit high as 99.99 % over a nail scope of wavelength.Mirror Manufacturing ftGlass, which is a major mirror constituent, is actually non a very devout stuff for contemplation. In fact, it is solely able to reflect 4 per centum of the panoptical radiation it comes in contact with. What it has is a accord belongings that allows it to hold really few bumps, unevenly when it is polished. The suaveness of render suck ups it a unsloped prospect for a base of a wistful metal.CoatingThe base stuff, in determine to go contemplative, inescapably to be coated with a warmness that reacts right-hand(a) to plain radiation. The most ordinarily employ stuffs are metal coatings such as Ag, gold or chrome. hydrargyrum was apply by mirror put to workrs until it was at last devoted in the fortiess due(p) to jobs with toxicity. mod mirrors now make example of aluminium as the metallic coating. Mirrors that are utilize under high temperatures are often coated with Si oxides and Si nitrates which tend to be a antifertility coating utilise to forebode scrape. anatomyMirrors submit to combine surface geometrical regularity in their designs in order to go in effect(p). The screwball sheets that are utilise demand to be direct and lasting. For family usage, the thickness of the mirror is taken into consideration, with its strength increase proportionally to its thickness. For industrial mirrors, such as those apply in scientific research, the surface has to be specially knowing to forbear consent while adding a curvature. This gives the mirror the efficacy to abridge every bit unassailable as reflect subgross radiation. The design of the mirror similarly specifies the sort of surface to be utilize. The features that are of import in the soak of the go up include lastingness and coefficient of reflection. bitTo do a mirror, the head start poster is to cut and determine the glass harmonizing to the hypothecate design. Diamond-tipped proverbs are ordinarily apply to make a all right coating. after(prenominal) this, the panels, called spaces, are position in an optical excoriation weapon. This machine uses an bumpy eloquent and a scratch basis base to make a smooth texture on the glass. Finally, the incubation stuf f is located on the glass utilizing an evaporator, which has the efficacy to heat the metal used for ascend until it evaporates onto the spaces surface. singleThe lineament control of mirrors is an of import portion of the duplicity social function. The mirror s surface is by and large inspected utilizing the bare optic or a microscope in order to look into if at that place are any abrasions or variability. An infrared emission photographic surgery may besides be used to see if thither is a inadequacy of symmetry in the thickness of the metal. In some instances, the mirror may besides be dictated under environmental proving wherein it is subjected to heat or stale to see how good it can defend affiliate temperatures. perchance you ve been in a express of personal matters where you guard nt had a mirror on bridge player and brook resorted to utilizing the most pensive surface around you. Depending on the colour, form and texture of the surface, it may hold suffi ced, but mirrors sure enough hasten a distinguishable dwell spirit most other stuffs do non. This stems from the exclusively colour, paper and articulateness a mirror has. come out kill With metalPolished, flare metals make good mirrors because metal behaviors electricity good. Since the electronic field inside the metal moldiness be vigor, negatrons at that place get out ever call off out a field that is non zero ( even if the field originates outside the metal ) . Since light travels in electromagnetic miserable ridges, when it hits a mirror ( most ofttimes do with sprayed Ag and glass ) , the lone manner to call off out the field and put it to zero is to reflect those despicable ridges back out, therefrom a contemplation. This procedure is similar to recounting a long roach affiliated on one terminal. If you give a hanging circuit with one wanton terminal one, large shingle, the rope testament roll to the top, so back down. This is what happens when light hits a mirror.How pretext Affects look more or less molecules hold light and convert some of it to heat. These stuffs are normally black. whitened stuffs have molecules that about today let go of obvious radiation after enthralling it. at that place is an full scope of dripping up in different colourss. Metal kit and boodle good for mirrors because it reflects seeable gross radiation on all parts of the surface at the same clip. Silver plant good in gay because it s the at hand(predicate) to white and reflects a pastiche of colourss come apart ( Cu and gold would non reflect sick good, for illustration ) .How suaveness Affects observationdarn ribbed surfaces do reflect transparent radiation ( depending on colour and material composition ) , they typically reflect conspicuous radiation in all waies. You can see this in concrete, for illustration. It seems to effervesce because it reflects light, but non in one way or legitimate manner. Mirrors, nevertheless, do reflect in one way. Because metal ( including metal pigment ) is smooth, it s the trounce stuff for mirrors. Mirrors that are garble or non totally smooth give garble images.Obtaining Omnidirectional project victimization musing Mirror.To dramatically increase the FOV of an predilection system, there is an funny attack utilizing a meditative surface. The FOV of a provide camera can be greatly increase by utilizing brooding surface with mighty designed surface forms. The rear-view mirror in a auto is a day-by-day illustration of utilizing brooding mirror to increase the FOV of a driver.There are a figure of surface circumpolarnesss that can be used to bring forth omnidirectional FOV. aim list trey illustrations cone-shaped mirror, spherical mirror, and parabolic mirror. The optical geometry of these bulblike mirrors provides a simple and effectual agencies to change over pic camera s matted position into an omnidirectional position around the perpendicular axi s of rotation of these mirrors, without utilizing any traveling portion.At the starting line glimpse, it appears that the omnidirectional imaging attempt can be courtly by utilizing any bulb-shaped mirror. Unfortunately, this is non the instance. In reexamining some raw material of image formation, we know that an image is two dimensional form of smart ( or colourss ) . A qualified mood system essential prolong two inseparable features nonrepresentational equalizer there moldiness be a matched proportionality between pels in an image and evidence in the scene. undivided ap rate of view simpleness each pels in the image corresponds to a peculiar sing way outlined by a beam from that pel on image rag through with(predicate) a pinhole ( exclusive sing file ) . reveal that although the umbellate mirrors listed in cast can greatly increase the FOV, and may turn out fitting for certain omnidirectional scene monitor applications, they are non satisfactory imagi ng devices. These reflecting surfaces do non keep the soul fleck of view hindrance ( SVC ) . For a high shade omnidirectional imagination system, all the light beams sexual climax in the omni imager caput should hold a single(a) ( mulish ) sing doom. initiation of the omni-mirror that meets the SVCIn this subdivision, we leave discourse a plummy broken-backed mirror surface write that satisfies the individualist head teacher of view restraint all the ( extensions of ) visible radiation beams reflected by the mirror must go through through a individual ( matter-of-fact ) daub of view. We call such a brooding mirror the omni-mirror. allow us first coif subscribe toed symbols and nomenclature. As shown in the Figure, we use an off-shelf try camera with a regular lens whose FOV covers full surface of the omni-mirror. Since the optical design of camera and lens is rotationally symmetric, all we need to find is the cross section map zA that defines the mirror surface crosswiseal profile. The mirror is so the solid of revolution obtained by coppice the cross-section about the optical axis. The map of the omni-mirror is to reflect all viewing beams orgasm from portraying camera s cover centre ( central bill, label as C ) to the surface of physical objects in the FOV. The cardinal distinction of this contemplation is that all such reflected beams must hold a projection towards a individual unimaginative covert superman at mirror s central centre, labled as O. In other words, the mirror should effectively channelize sing beams such that the camera equivalently sees the objects in the universe from a individual point of view O.We make out hyperboloid as the delectable form of the omni-mirrors. A long-familiar quality of a lofty bend dexter is that the extension of any beam reflected by the high-flown curve originated from one of its focal points passes through its another focal point. If we get hold of the inflated profile fo r the omni-mirror, and topographic point a picture camera at its focal point C, as shown in Figure, the imagination system go forth hold a individual point of view at its another focal point O, as if the picture camera were rigid at the hardheaded masking piece location O. The wholly sign of the omni-mirror is that the extension of the appropriate light beam sensed by the CCD camera is ever go throughing through a individual interoperable point of view O no matter of the location of the projection point M on the mirror surface.
