Perspectives on Vulnerability in Childhood

Perspectives on Vulnerability in Childhood The aim of this assignment is to discuss critically the principles of working with vulnerable children or young people by using an anonymousness case study. The plan is to illustrate the key concepts of vulnerability and resilience, consider the impact on the childs mental health and to look at different legislations. Scenario Mary is a five-year-old child who lives at home with her Mum and Dad. In view of the recent recession, Marys Dad has lost his job and is displaying negative emotions and this is causing friction with his wife. Mum has mild learning difficulties but is able to hold down a part time job, taking on more hours to compensate for the loss of earnings and leaving Dad to attend to Mary. Mary attends school but recently her attendance has been erratic, on several occasions Marys homework as not been done. School staff has noticed Mary turning up to school dirty, smelly and appears to have lost weight in recent weeks. The teacher has tried on several occasions to arrange a meeting but Mum claims to be too busy with work and Dad shows no interest. Vulnerability An explanation by Appleton (1994) describes vulnerability as a complex concept where there are many interacting factors. Appleton (1994) suggests vulnerability can be viewed as a scale where families at different periods in life can be more susceptible to both internal and external stress factors. In comparison, The United States Agency for Health Care Policy and Research (USAHCPR 1998) suggests that the environment may contribute to the vulnerability of people through various phases of life. More specifically different people may be vulnerable in a variety of ways due to health issues, age, communication problems and the house and community where they live. Equally important a recent concept of vulnerability suggests that parents or carers inability to provide basic needs, such as love, warmth, shelter and a healthy diet may affect the childs all round development. (Cleaver et al 2007). One cannot deny that everybody at some point in his or her life may be vulnerable. However, according to some experts how old you are can also be an influence. In other words, infants and children are considered more vulnerable because they rely on parents or carers to provide their basic needs. The reason for this is young children do not have the verbal language to communicate for their own needs (Aday 1993, Gitterman Shulman 1994, Miller 1995). Nevertheless all concepts advocate a similar meaning and according to the Convention on the Rights of the Child (1990) article nineteen, states that every child has the right to be protected. Young children need to be nurtured and guided by parents or caregivers to provide them with the basic needs to develop into participating young adults in society (Cleaver et al 2007). So it is vital that all nurses, midwifes and health visitors should have the skill and knowledge to identify indicators of vulnerability in children and be responsible t o pursue any concerns with the appropriate person (Stower 2000). Resilience In the science of human development, resilience has comprehensive and different meanings, including recovery from traumatic experience, overcoming divorce and withstanding stress to function well in the tasks of life. It is clear from those facts that resilience refers to patterns of positive adaptation or development manifested in the context of adverse experiences (Masten Gewirtz 2006). Masten and Gewirtz (2006) suggest that resilience is a dynamic balance between risk and positive factors. In addition, how individuals, children, and families cope in the face of adversity. This led us to believe through research that early childhood is a significant time where parents can nurture the characteristics of the children in promoting and understanding resilience (Masten Gewirtz 2006). Furthermore, Masten and Gewirtz (2006) suggest that resilience may come naturally to some children where other children may need help in acquiring those skills. One should, nevertheless consider resilience from another angle where existence of protective factors may explain why one child may cope better with adverse life events than another (Getting it Right for Every Child 2008). Protective factors are those variables that safeguard against the effects of risk factors, the presence of one or more factors of negative outcome for a child or young person. Protective and risk factors can be divided into four groups, child, family, school, and community factors (Durlak 1998). An example of a risk factor would be insecure attachment and the protective factor would be attachment to a family (Durlak 1998). With new information and understanding of resilience in individuals there seems to be a shift from the emphasis on factors and variables to mechanisms and processes. This shift looks at how well an individual processes and copes in the face of adversity (Rutter 2007). Furthermore, this refers to mental operations, for example coping skills, as well as individual characteristics and experiences (Rutter 2007). On reflection, it seems more accurate to say that considering not only characteristics and experiences but also the age and stage of development of the child. In addition, for example children aged five and less has a reduced repertoire of coping mechanisms. Similarly, Schoon (2006) suggest resilience is not only dependent on the characteristics of the individual but interactions from the family and the wider community may also play a part. On the other hand, Brooks (2006) points out that the family is at the centre of providing care and this has the greatest influence on the development of resilience in children. In relation to the scenario, Marys all round development at this moment may be vulnerable. As highlighted above how old you are can also be an influence because children aged five and less has a reduced repertoire of coping mechanisms and the increased of vulnerability in this age group in terms of physical and emotional development. Mary is dependent on her parents to provide her basic needs, food, warmth, shelter, and love. The effects of neglect can have a long-term influence on Marys quality of life. However, some children cope with and overcome the socio-emotional effects of child neglect. Mary may have protective factors within the family, such as a Grandmother, who may help to reduce the effects of neglect and foster resilience. The family dynamics have changed within the family where Mum is now working full time and Dad is the main caregiver. In view of the recent recession, Marys Dad has lost his job and is displaying negative emotions. This may have an impact on Marys all round development and her mental health because are social skills and needs is not being met. Mental Health In relation to the scenario, Mary is showing signs of neglect. To begin with, according to Horwath (2007) there have been many publications about neglect. However, not one was able to give a clear definition on what is neglect. In addition, analysis from these definitions agrees that neglect is an omission, or failure on part of the parent or carer to provide the basic needs for the child, such as healthy diet, and love (Horwath 2007). Likewise, the National Society for the Prevention of Cruelty to Children (NSPCC 2007) agrees that neglect is difficult to define and describes it as a complex phenomenon. However, both the NSPCC (2007) and Horwath (2007) agree that neglect in practice can present short term to chronic and severe neglect. Furthermore, periodic failure or one-off incidents can have a significant effect on a child. These periodic and one-off incidents may be indicative of developing neglectful behaviour. Another possibility it may be an indication that the family is suffe ring from stress, or a temporary crisis because of parenting issues (Horwath 2007) such as Marys Dad has been made redundant. When people hear the word neglect, they usually think of parents not providing their children with food, clothes, or a safe environment to live in. Alternatively, parents can neglect their children (Horwath 2007) in other ways. Furthermore, Horwath (2007) suggests that there are a variety of parenting behaviours that may be classed as forms of neglect such as, medical, nutritional, education and emotional. Parents or carers who emotionally neglect their child fail in providing physical or emotional affection and do not develop the childs sense of self-worth and positive identity (Horwath 2007). More specifically, it affects the childs all round development including their mental health. Mental health can mean different things to different people. For children to be mentally healthy they need to be loved, healthy diet, and opportunities to make choices, protection from risk, and shelter. However, the list is exhaustive but more specifically according to young minds (2002) children who live life to the full, creative and sociable lives, cope with difficulties and frustrations are mentally healthy. The foundation for building emotional understanding skills has been found to develop within the parent-child relationship (Parke et al 1992). According Edwards, Shipman, and Brown (2005) through the parent-child relationship children learn from their parents how to label and interpret motions in different situational contexts, when it is appropriate, how to show and evade emotional experiences as culturally indicated. The ability to interpret the emotional behaviours of others may mean reading their facial expressions, by the tone of voice or body language, not necessarily words (Edwards, Shipman, and Brown 2005). In addition, children who developed emotional development at a young age are more likely to settle well into school, work cooperatively, confidently and independently, and behave appropriately (Townley 2002). A child with poor social and emotional development is at risk of poor relationships with peers, academic problems (Horwath 2007). There is a difference between emotional neglect and emotional abuse. According to Iwaniec (1995) suggests that emotional neglect is non-deliberate where abuse is deliberate. Furthermore, parents or carers can emotionally neglect their children in a number of ways such as, inadequate attention to the childs needs, need for affection, and lack of emotional support (Iwaniec 1995). All children are individuals and may experience mental distress in different ways, such as the inability to cope with problems and feelings, low self-esteem and self-confidence, worsening school performance, and social withdrawal (Honeyman 2007). Emotional resilience is a valuable skill for all children. It is about being in control and believing in ones ability to work through setbacks and risk situations in a capable, effective manner. This capacity for resilience empowers the child to develop coping behaviours, to persist in the face of failure, to bounce back with confidence and a healthy self-esteem (Townley 2002). Children need a certain amount of resilience to be able to cope with the difficulties that occur as part of living and other strong emotions, in order to do this children develop a number of coping strategies (Landy 2002). For the first five years, children rely on their parents or caregivers to provide support in dealing with intense negative emotions and eventually learning to control or manage their emotions alone by using a range of emotional resilience or coping strategies (Landy 2002). Therefore, children need to understand how to regulate their emotions, recognize emotions in others, and handle relationships with others if they are to be well-adjusted, contented, positive, and resilient individuals (Townley 2002). They need to learn that all emotions are okay, and that they are entitled to their emotions (Cassidy et al 1992). However, it is also important children recognise that other individuals emotional needs can differ from their own (Horwath 2007). Another aspect to consi der is how the parents socialize with their children and display emotions. If the parent or caregivers display positive life skills rather than displaying anxiety or depression therefore the childs capacity to emotionally regulate would not be impaired (Landy 2002). Mental health affects all aspects of life how Mary forms relationships, interact with her peers and how she copes with the rough and tumble of life. A child who is ignored may seek other ways to draw attention, and the ability to cope may be hinder leading the child to have a strong tendency to use externalizing and maladaptive coping skills. Marys life is loaded with tension, negative moods, unpredictable parenting at this moment in time. In addition, the school have contacted both parents to discuss issues relating to Marys education and well-being however, her father is not interested and Mum claims to be busy with work. The expression both parents are portraying now about school is indicating to Mary that school is not important and she may be less likely to seek emotional support from teachers or her peers. On the other hand, up to now one may assume Mary has had a stable upbringing and with additional support and with protective factors in place may help her through the present crisis within the family. Legislations There are different legislations in place to protect children and young people in todays society. Such as, Protecting Children and Young People: Framework for Standards (Scottish Executive 2004), The Children (Scotland) Act 2004, and Sharing Information About Children at Risk of Abuse and Neglect: A Guide to Good Practice (Scottish Executive 2004). There are many more policies but advocates that all children have the right to be protected. According to CAMHS Standard, National Service Framework for Children, Young People, and Maternity Services (2004) suggests multi-agency services work in partnership to promote childrens mental health, provide early intervention, and meet the needs of the children that are identified with problems. It also goes on to say that, staff who are working with children and young people have sufficient knowledge, training and support to promote the psychological well-being of children, young people and their families and to identify indicators of difficulty . However, this seems not to be the case and according to Honeyman (2007), it is a much-neglected subject in child health. The Nursing and Midwifery Code (2002) states that this lack of knowledge in mental health may be seen as a barrier When making decisions about a child it is paramount, they are at the heart of the discussion in all considerations and decisions. Professionals throughout the planning and actions taken must demonstrate this (Edinburgh and Lothians Inter-agency Child Protection Procedures Section 2, 2007). Furthermore, working with a family where they may be issues of the child or development professionals must co-operate to enable proper assessment of the childs circumstances, provide any support needed, and take action to reduce the risk to the child. Sometimes this may require sharing information with other professionals. In addition, all professionals or agencys are required to keep confidential information given by parents and must not be shared without the persons permission (Edinburgh and Lothians Inter-agency Child Protection Procedures Section 2 2007). Getting it right for every child (2008) is a network of support to promote the well-being of every child or young person to get help at the right time. This network will also include the family or carers. This may involve other agencies to be involved and if this is the case a lead professional will be nominated and they will co-ordinate help, such as making sure the family, child or young person understands what is happening and to promote teamwork between the agencies and with the family, child or young person. The Getting it right for every child Practice Model consists of three elements, Eight Well-being Indicators, My World Triangle, and The Resilience Matrix. The Eight Well-being Indicators, this identifies all areas where a child or young person needs to progress in order to do well now and in the future. This enables professionals to structure information that may highlight areas of concerns and needs and to structure planning (Getting it Right for Every Child, Section 4, 2008). My World Triangle introduces a mental map, which enables the professionals to understand the whole world of the child or young person. In relation to Mary, using My World Triangle can be used at every stage to think about Marys world. Information may be used from other sources, possibly school, to identify the strengths and pressures in Marys life. This will not only identify the negatives but also the positives as well. My World Triangle looks at the whole child, physical, social, educational, emotional, spiritual, and psychological development (Getting it Right for Every Child, Section 4, 2008). Using My World Triangle, the professionals can consider systematically how Mary is growing and developing, what Mary needs from the people around her, and the impact on Mary in the wider community, family, and friends. To conclude the professionals may use The Resilience Matrix. The Resilience Matrix can be used in a single or multi-agency environment. This allows the professionals to gather the information on Mary, from My World Triangle and other sources and plot it on a blank matrix so that the balance between vulnerability and resilience, and adversity and protective factors can be weighed. The City of Edinburgh Council, Guidelines for Pupil Support Groups (2004) are committed in working in partnership with the parents, Social Work, Education and others to provide integrated support to children or young people and their families. Mary is in Primary one at school and the teachers and staff are in a good position to observe Mary in her education, socialising with her peers and her general well-being. Conclusion Many researchers have highlighted that vulnerability and resilience are difficult to define. Through my research for this assignment, I have been introduced to a number of concepts in relation to vulnerability, resilience, and mental health in relating to a young person or child. It is the job of any paediatric nurse not to diagnose but be able to recognised symptoms of children with mental distress in order to refer them to the appropriate professional or agency. In addition, how important it is for the nurse to understand the age and stage of development the child goes through. Prolonged emotional neglect or any type of abuse may be harmful to the child. It has been highlighted through research that it may affect the childs all round development and the presence of protective factors may explain why some children are resilient and why others are not. Resilience can be enhanced through extensive and appropriate practical and emotional support, intervention, and life chances. In orde r to enhance resilience professionals must establish the vulnerabilities and protective factors that exist for the child them consider the course of action to take to enhance resilience. .

Slavery and Reparations Essay examples -- Slavery Essays

â€Å"Slavery, colonialism and neo-colonialism have caused inestimable damage to billions of people throughout the world. They have also formed the basis for the accumulation of immense wealth in the hands of a small elite†¦ The slave trade involved the brutal relocation of tens of millions of people in which families, communities and societies were destroyed and in which millions lost their lives in the most inhumane conditions. At the same time, slavery was a fundamental element of the strengthening of mercantile trade and the rapid accumulation of capital that formed the basis for the emergence of the capitalist system as we know it today. Colonial conquest entailed the further oppression of the people of the colonies in the form of dispossessing people of their land and their livelihoods, destroying their cultures and social and political structures and subjecting them to the rule of the colonial powers. Colonialism, in both its early expansionary phase and the imperialist phase in which the colonial powers carved up the world amongst themselves, created the conditions for the further accumulation of capital as well as the concentration and centralization of this wealth into fewer and fewer hands. Neo-colonialism continues and intensifies this oppression, leading to levels of poverty and destitution†¦ never witnessed before. The big transnational corporations, the governments of the North and the international institutions, including the World Bank, International Monetary Fund and World Trade Organization, are working with new elites in the South to perpetuate the process whereby the rich get richer at the expense of the poor getting poorer.† (JubileeSouth â€Å"Reparations Towards Another World†) An institution that lasted f... ... African Americans, then supporters, activists, lawyers, and the Black community all could stand behind one unified proposal. A proposal that is similar to Japanese-American redress that would seek to compensate individuals, the Black community through education and trust funds that would appreciate over time, and finally be recognized for the atrocities that slavery had on the African American existence in America. There is no question that slavery was both morally and ethically wrong, but somehow our country has become very comfortable with ignoring the impact that slavery had on the Black community. Even though slavery ended over 200 years ago the disadvantages of being Black in America still exist, and until the U.S. government begins to rectify their actions, blacks will continue to lose opportunities and will be no better off than their emancipated ancestors.

Social Welfare System in Hong Kong

Question 1: Identify one type of the social welfare, discuss its services of Hong Kong and a)explain its values, rationales and objectives; b)ways of service delivery; c)discuss the strengths and weaknesses of the service and d)make suggestions to improve the services in future. CSSA—AN INTRODUCTION The comprehensive Social Security Assistance Scheme (CSSA) is surely one of the most influential social welfare in Hong Kong, in terms of money and beneficiary.In the fiscal year of 2010 alone, 19 billion was spent on CSSA, which increased noticeably by 40% as compared with the expenditure ten years ago. As at the end of 2009, total number of CSSA cases amounted to 289 139, representing an increase of 25. 3% over 1999. CSSA accounted for 8. 6% of government recurrent expenditure, compared with 7. 5% in 2000. During 1999 to 2009, the average growth in total number of cases per annum was 2. 3%. In fact, the growth rate of CSSA cases is expected to accelerate because the growth of eld erly population will peak in 2016-2026.In other words, the problem is not coming yet. But it will within 10 years. In view of the potential alarming situation, there is an urgent need to investigate the effectiveness of the scheme. This essay will give a brief review of the captioned scheme as well as to discuss possible ways to improve the services in the future, making the most effective use of government resources. CSSA—ITS VALUES, RATIONALES AND OBJECTIVES The CSSA Scheme was introduced in 1993, replacing the former Public Assistance Scheme, and evolved over the past 20 years into the current complex system.It is designed to provide a safety net for individuals or families who cannot support themselves financially for various reasons such as old age, disability, illness, unemployment and low earnings. The CSSA Scheme provides financial assistance to bring the income of such individuals or families up to a prescribed level to meet their basic needs. All CSSA recipients are entitled to free medical treatment at public hospitals or clinics. It is administered by the Social Welfare Department (SWD) and is non-contributory but means-tested.APPLICATION REQUIREMENTS To be eligible for assistance, the applicant must satisfy the residence requirements, that is, to have resided in Hong Kong continuously for at least one year before the date of application and be a Hong Kong resident for seven years. Yet, exception can be granted for discretion. They must also pass both the income and assets tests. To pass the income test means the applicant’s total assessable monthly household income is insufficient to meet their total monthly needs as recognized under the Scheme.To pass the asset test means the total value of the capital assets held by the applicant is below the prescribed limit. If the applicant lives with other family members, the application shall be made on a household basis. On top of the basic subsistence support, there is a number of supplement s, like disability, old age, community living, single parent, transport supplement, which is too excessive to mention here. A person can make an application directly to a social security field unit, or by referral to the Social Welfare Department by another government department or a non-governmental organization.Upon receipt of an application, staff of the SWD will conduct investigation and verification of the applicant’s circumstances. It is usually completed in a month and is very convenient. CSSA—ITS STRENGTHS AND WEAKNESSES Generally speaking CSSA has been quite effective in providing a safety nets towards the needy, whether the amount of grants is sufficient or not is subject to argument, one has to acknowledge the fact that there is no major starvation/freezing death caused by poverty in recent years. The general living conditions and nutrition’s of the poor improved, compared many years ago.In the past, social welfare is just a feeding station, or remedy measures after the problems exist, CSSA, with its recent reform of adding more and more subsidies like disabilities, elderly, transport supplement†¦etc, is a rather complicated cash transfer framework, which definitely, effectively created a safety net and contributed a part of improving peoples’ living standard. It seems that CSSA was able to fulfill the very basic philosophy of social security policy and social policy in general terms, which is residual or remedial. CSSA is somewhat a passive scheme as a rescue if the applicant himself, or his family failed to help.It is remedial because it functions only if you fall and will not prevent you from falling. This is of no doubt that CSSA can solve immediate issues, but not the root of it. In fact there are changes that CSSA can make to help better cope with this problem. Moreover, there is room of improvement of the efficiency of the scheme, as it has become more and more complex that something can be done to make it mor e efficient as a safety net. And as progress, it is vital that we look at the possible policy that can be adjusted to better cope with the situation as things do change over time.One of the major characteristics of CSSA is that it is a means tested scheme. In a nutshell, as long as the applicant meets the requirements, the applicants are entitled to get the benefits, as a matter of right. What they do is to assess the quantitative elements of the applicants, such as how many assets they have, how much they earn per month, the severity of his sickness, and treat them as fair as possible, without looking at their background, their ability, the reason they apply for the scheme.As a government servant, I comprehend the difficulty to do so because their job is to do assessment on the financial criteria. But CSSA is not just simple financial assistance, ideally speaking. When the unemployed come for assistance, their problem is not just short of money for assistance, they are unable or no t willing to find jobs which they do not like or do not match their skills or think the wage is too low for him. Recent news reporting a postgraduate graduated from The Chinese University of Hong Kong is an example. CSSA applicants have problems besides financing.I dare say a considerably proportion of staff running the program are not equipped with the skills that can deal with the key issue, thus missed the chance of preliminary investigation of the candidate while looking at the documents and data before the grant. However, CSSA is far from sufficient to provide something constructive, to help the recipients for taking constructive acts to participate in society. Right now we see that, the community is increasingly dependent, which is harmful. The CSSA should abandon the passive strategy of simply looking at needs and handing out cash.This can be done by demanding the recipients to take steps to help themselves as a prerequisite to receive the payments. It has in fact already bee n adopted and have a positive result. With the introduction of the intensified Support for Self-reliance Scheme measures in June 2003, there was a rapid deceleration in the rate of increase in unemployment cases during June to September 2003, the number of cases also started to decline as from October 2003 to October 2008. But the unemployment case started to rise since 2009, and almost reached the level of 1999, which is the year of financial crisis.As a suggestion, the said scheme can add community service work as a component of the criteria of getting subsistence, such as to clean toilets in governmental departments, of some minimum hours per month as a way to encourage them to contribute to the society. Back to the postgraduate in CU as an example, of course he will get something better than looking after elderly as a job! Even if he cannot do so what he has done will be beneficial to the society. Moreover, the scheme is becoming more complicated as more and more supplement and discretionary items have been added.It is no longer a system that is administratively simple or efficient. The lack of training of the said officials and the complexity the system deter the efficiency of the officials to tackle the applicants specific needs, rather in a degree enhanced their reliability on CSSA. Alternative of solving the problems, despite of training workers, is to tidy up the current structure of the administration, such as diving the recipients into categories, with their own eligibility criteria, referrals, conditions of assistance and kinds of help to offer.Bureau working on this will be, despite more systematic, will have a much more clear idea of how to help the applicant and in turn, the applicant received a better idea of their benefit and get better helped. For instance the financial needs of the elderly should be considered with their health care. They may, because worrying insufficient money to pay their health care, save the already little grants receiv ed from CSSA, sacrificing their living quality. There seems little cooperation with the Social Welfare department with relevant charity organizations.The same applies to other groups, like, for single parents family, which they save the CSSA for family services. I have already made the point through the above that CSSA, generally speaking is effective and have done a good job in providing a safety net to Hong Kong, by a one-way handout of cash. But it can, in fact, requiring the recipients to contribute back to the society by adding a component of voluntary services element into the scheme. This, on one hand can screen out people who do not really need CSSA, thus focusing to the resources and attention to those desperately in need.And on the other hand to help those screened out forcing them getting back to the mainstream. And as mentioned about, the efficiency of the CSSA system can be more efficient by adopting a categorical approach, better matching the skills of staff working th erein and the background of recipients. In a nutshell, CSSA do create some sort of dependency because, looking at the amount of CSSA cases and the economy of Hong Kong it is not very much correlated. That suggests that the determining factor for the number of people on welfare is, maybe the welfare system itself.Therefore it is very critical for the government to formulate its social welfare policy so that the policy will not create dependency by itself, better organizing structure of manpower, so the budget can save a few billion and most importantly, better matching of resources and helping those really in need.

Four external forces that affect an Organization Essay

Terms of reference: This report was commissioned by the lecture of Management and Organisation Behaviour as individual assessment on four external forces that can currently affect Organisation for these modules within the Bachelor of Business Degree in Management. Introduction: In this assignment I will present a brief literature review of the main four external forces that can currently affect an organization (a business). First I will introduce global economical powers that influence the four external forces after that I will then introduce the four forces in more detail. Global perspective As the world is emerging from the waters of deep economical crisis I think the best to start with are global influences that affect the main four forces. Each organization is directly strongly influenced by general laws of economics: Economic growth – is influenced by various factors such as development on stock markets, which is strongly influenced by political activities around the world, prices of raw materials (metals, oil etc.) but also prices of energy and future of the economical development in general. Inflation – increases cost of operations and price of products and reduces employment. Interest rates – as many businesses operate with money borrowed from banks changing interest rates influence directly interest expense, which influences the cost of operations and the cost of product PEST Macro analysis Each local business is based in a certain environment that directly influences its performance. The environment a company exists in has a strong impact on every aspect of the company`s life. The following main four macro-economical external influences are interdependent. Political atmosphere – each country has a specific political atmosphere, political culture. For instance countries of the EU would have very different atmosphere to North Korea. Local political decisions shape the countries economical perspective and enable or disable, speed up or slow down the development of local businesses. Political decisions directly influence law of the country (region) and some of them such as economic reforms make strong and long-lasting impact on local businesses. Even political decisions such as annual budget or introduction of income levy  have profound impact on business performance. However this would be more applicable in Adam Smyth`s times. Currently we can still apply this influence of local politics on small or local businesses but the late seventies and eighties of the 20th century, started especially in the Euro-American civilization process of progressive economic liberalization that resulted in supra-national corporations that we know today. Many of these corporations are wealthier then countries they operate in and often dictate what the local political milieu will be. This route would eventually lead us to the question of monopolization and to the question of economic and political interests and their balance. Ultimately it is both international and local law that that create balance between these two areas.1 Great example of politics and law (even if enforced by the international public rather than by local corrupted politicians) impacting on businesses is from India, where supra-national companies producing clothing completely ignored health and safety regulations in order to produce more and cheaper. Unfortunately this lack of political ethic and responsibility resulted in tragedies and loss of many lives. Social environment – main characteristics of social environment are social norms and cultural and even religious preferences. Max Weber sees the protestant idea of hard work as a result of original sin as the inspiration for development of hard-work and profit focused capitalism. 2 This idea of hard-work and profit focused capitalism combined in Europe and in the North of America with culturally well established system of banks borrowing finance for interest resulted in today`s macro economical models. Euro-American banking system is historically based in certain interpretation of oral Torah called Mishna that allows borrowing money for interest in return. It was in historical Europe traditionally â€Å"allowed† only to the Jewish nation as a form of discrimination and punishment. So the development of economy is we know it today would be very unlikely in many parts of the world simply for cultural and religious reasons as in some countries would be money coming from interest prohibited.3 Demographic profile of social environment is crucial for any business existing within that particular society. Gender, age, ethnicity, language, education, public opinion and norms influence every aspect of business. Gender norms define approach of  society towards male / female work.4 In many societies is female work traditionally under-rated therefore from the perspective of operations management it is cheaper for companies to employ women in certain positions. Education of population leads us into the next factor that affects business†¦ Technological development – is a result of the impact of education in the local social environment; technological changes always initiated further development. The invention of wheel accelerated speed of movement of our ancestors, the invention of metals improved their farming instruments as well as weapons but here we are not talking about the long time gone past. Today we live in exciting times of technological changes, which are changing the face of businesses on daily basis. Internet and electronic communication speeded up every aspect of business from operations, logistics to client services. Even the smallest local newsagent or grocery shop must keep up with the development of recent technologies. 20 years ago it would be absolutely unthinkable to top up phone credit while paying for grocery in a local shop. In fact there was no topping up credit at all today. Today we would find it rather odd if our local newsagent (if we still buy newspapers) would not have a top up terminal. Purchasing a flight used to be in general one to one experience; we used to go to travel-agents or flight-companies directly and purchased flights. Today we find normal to use the internet at home even to check in before our flight. A flight company that would not offer internet service to purchase a flight would not survive today. But all this technological progress would not be possible without investments, without wealth. Economical environment – wealth as a source of investment was based in times of Adam Smyth and his An Inquiry into the Nature and Causes of the Wealth of Nations in productive powers of Labour, in accumulation and employment of stock, in progress of opulence in different nations (which is the distribution of wealth between cities and countryside) and in a system of political economy. 5 Today is material wealth accumulated not so much in nations but more so in supra-national companies. Still effective investment is the fuel of business development. Economical environment and wealth  depends as we already mentioned on macro-economic factors of global economic growth, inflation and interest rates that directly influence local currency inflation and interest rates increase or decrease. Global economy fluctuates from booms to slumps. Most businesses gain in booms and loose in slumps. Bibliography: Swedberg, R. (2003).

Xenosmilus - Facts and Figures

Xenosmilus - Facts and Figures Name: Xenosmilus (Greek for foreign sabre); pronounced ZEE-no-SMILE-us Habitat: Plains of southeast North America Historical Epoch: Pleistocene (one million years ago) Size and Weight: About five feet long and 400-500 pounds Diet: Meat Distinguishing Characteristics: Large size; muscular legs; relatively short canines About Xenosmilus The body plan of Xenosmilus doesnt conform to previously known saber-tooth-cat standards: this Pleistocene predator possessed both short, muscular legs and relatively short, blunt canines, a combination that has never before been identified in this breedthough paleontologists do believe Xenosmilus was a machairodont cat, and thus a descendant of the much earlier Machairodus. (The unique skull and tooth structure of Xenosmilus has inspired a peculiar nickname, the Cookie-Cutter Cat.) Its as yet unknown whether Xenosmilus was restricted to southeast North America, or was more widely distributed across the continent (or, for that matter, ever made it down as far as South America), since the only two fossil specimens were unearthed in Florida in the early 1980s. The most striking thing about Xenosmilus, besides its cookie-cutter bite, is how big it wasat 400 to 500 pounds, it was just shy of the weight class of the largest known prehistoric cat, Smilodon, better known as the Saber-Toothed Tiger. Like Smilodon, Xenosmilus clearly wasnt suited to stalking or pursuing prey at high speeds; rather, this cat would have lounged in the low branches of trees, pounced on slow-witted megafauna mammals as they passed by, dug its cookie-cutter teeth into their bellies or sides, and then let go and leisurely followed them as they slowly (or not-so-slowly) bled to death. (The bones of peccaries, a type of pig native to North America, have been found in association with Xenosmilus fossils, so we at least know that pork was on the menu!)

DEET Chemistry (Dimethyltoluamide)

DEET Chemistry (Dimethyltoluamide) If you live in an area with biting insects you have almost certainly encountered an insect repellent that uses DEET as its active ingredient. The chemical formula for DEET is N,N-diethyl-3-methyl-benzamide (N,N-dimethyl-m-toluamide). DEET was patented by the U.S. Army in 1946 for use in areas with heavy biting insect infestation. It is a broad-spectrum repellent that is effective against mosquitoes, flies, fleas, chiggers, and ticks. DEET has a good safety record and is less toxic to birds and other mammals than many other insect repellents, but all DEET products should be handled with care. DEET Safety DEET is absorbed through the skin, so it is important to use as low a concentration as is effective (10% or less for children) and as small an amount as is necessary. Up to a certain point, protection against insects increases with higher DEET concentration, but even low concentrations will protect against most bites. Some people experience irritation or an allergic reaction to DEET-containing products. DEET is toxic and potentially fatal if swallowed, so care should be taken to avoid applying repellent to hands or face or anything a child might put in the mouth. DEET should not be applied to areas with cuts or sores or around the eyes, since permanent eye damage can result from contact. High doses or long-term exposure to DEET have been associated with neurological damage. DEET can damage some plastics and synthetic fabrics, such as nylon and acetate, so be careful not to damage clothing or camping equipment. How DEET Works Biting insects use chemical, visual, and thermal cues to locate hosts. DEET is believed to work by blocking the chemical receptors for carbon dioxide and lactic acid, two of the substances released by our bodies that serve as attractants. Although DEET helps keep insects from locating people, there is probably more involved in DEETs effectiveness, since mosquitoes wont bite DEET-treated skin. However, skin only a few centimeters away from DEET is susceptible to bites. Recommendations for Using DEET Despite its hazards, DEET remains one of the safest and most effective insect repellents available. Here are some tips for using DEET safely: Reduce your need for repellent. Avoid behaviors that will attract biting insects (e.g., avoid strenuous exercise or eating lots of high sodium or potassium foods prior to going outdoors, which increase carbon dioxide release).Avoid applying chemicals that attract biting insects (e.g., floral-scented perfumes, scented sunscreens, dryer-sheet-scented clothes).Where possible, apply DEET-containing repellent to clothes rather than to skin.Apply DEET in a well-ventilated area.Avoid applying DEET to hands, the face, or any injured or sensitive skin.Avoid behaviors that will lessen the duration of DEET effectiveness (e.g., perspiration, rain, mixing with sunscreens).When you come indoors, wash off DEET-containing products using warm, soapy water.

Abiotic And Biotic Characteristics Environmental Sciences Essay

Abiotic And Biotic Characteristics Environmental Sciences Essay San Francisco Bay has maintained a magnificent body of water and use to sustain the economy of Western United States and San Francisco Estuary in Bay in is of great importance because through this a large number of water draining becomes possible. It’s Estuary from where fresh water meets to sea water. There are many pollutants that we face in our daily life e.g. dirt, sediments, oil, grease, fertilizes pesticides chemicals etc. the water running from the land carrying these pollutants to underground and ultimately this reach to the Estuary of san Francisco. These pollutants when reach in river and sea water can pollute the whole water and prove harmful for aquatic life as it can be cause harm for wetland creatures like fish, and can prove very dangerous for other habitats of water. It can destroy the aquatic system and can be major threats for the living organism living under water. As San Francisco Estuary considered as a very important region and has much economic importan ce so for prevention of pollution and keep safe this region from other different factors restoration and conservation is used. Abiotic and biotic characteristics of the San Francisco Estuary Many of environmental factors affect the abiotic and biotic characteristics of the San Francisco Estuary these include both abiotic and biotic characteristics. These factors effects the life in Estuary in great extends. Non-living factors are called abiotic factors which include concentration of oxygen and nutrients, salinity of water and amount of sunshine. As these factors have the major impact on the life in estuary. All living factors that affect the estuary are called biotic factors. That includes producers’ consumers and predators as producers are of basic importance for consumers. Consumers rely on producers and predators rely on consumers. So these are depend on one another to maintain the balance of estuary, Population growth in the San Francisco Bay area affected the estuary Inc reasing trend of population in San Francisco Bay area affected the estuary as increasing trend of population cause a rush in urban as well as on village areas. More the people are using the recourses more the waste is creating and much use of water and water waste from its use create pollution as much of the polluted water is drained through the underground ways to Estuary that is a great threat for the marine life. More over in recent years 40,000 metric tons of pollutants enter the Bay annually from agriculture and urban runoff. Rivers, atmospheric fallout, municipal sewage treatment plants, industrial facilities, natural and artificial erosion, illegal clearance, dredging and dredged material disposal, marine vessel discharges, accidental spills, and landfill seepage are also causing problems as well. (1) Habitat fracture in the San Francisco Estuary been increased by human behavior Estuaries is of great importance for us as these are used for food, trade and for shelter and in t his case Sans Francisco Bay has great importance as it is used as harbor for many ships of this regions. There are large number of plants and animals found in Estuaries and the most of population of San Francisco Bay depend on these marine lives for their food. But due to the pollution spreading by increase in population cause harm to these plants and animals. This pollution can cause damage to the lives of these plants and animals found in estuaries.

World Trade Organisation (WTO) Essay Example | Topics and Well Written Essays - 250 words

World Trade Organisation (WTO) - Essay Example Another characteristic of WTO is that it endorses the idea of free trade agreements followed by resolution of conflicts and ‘trade negotiations’ among nations (BBC Profile, 2011). Answer 2 It should be pointed out that WTO is not a perfect organization neither it has been seeking perfection. As far as the positive side of WTO is concerned, it is justified to argue that the measures taken by this organisation have bolstered trade ties among countries as well as have resulted in phenomenal growth in global trade volume in last 13 – 15 years (more specifically since 1995). For instance, WTO has made a major contribution in globalisation and internationalisation of this world, thereby leading to interdependence of nations. In other words, a country having scarcity of food / agricultural products and oil could import them from foreign countries (having abundance) at reduced tariffs and meet the domestic demand. Similarly, the oil rich nations, with weak industrial base , could import machinery and manufactured products from their trading partners. Nevertheless, the WTO has also certain weaknesses and the most important one is its failure in eradicating protectionist policies. It should be recalled that protectionist policies refer to trade barriers and initiatives that help protecting domestic industries from imported products.

Risk Management Week3 - Essay Example on that ought to be proactively and effectively managed for a firm to identify and be able to react to new vulnerabilities, emerging threats, and a firm’s continuously changing enterprise operational and architecture atmosphere. Over the years, several security requirements and standards constructions have been developed in an effort to address enterprise systems together with important data inside them. Nonetheless most of these attempts have basically become exercises on just reporting on conformity and have in actuality redirected security programme supplies from the continuously changing attacks that must be dealt with. The Critical Security Control aims first on making it a main concern on security responsibilities that are efficient against the very latest Advanced Targeted Threats that has got a very tough emphasis on â€Å"what actually works†-security controls whereby processes, products, services and architecture are being used and have actually proved real world efficiency. Automation and standardisation is yet a further top main concern, to increase operational competences while at the same time improving efficiency (Hossein, 2006). There are several critical security controls that this paper seeks to address .Some of these include; inventory of unauthorised and authorised devices or software, making sure there is secure configurations for software and hardware on laptops, servers, mobile devices and workstations, continuous vulnerability assessment and remediation, application software security, malware defenses, wireless access control, appropriate training and security assessment to fill in gaps, data recovery capabilities and finally secure configurations for network tools such as routers, switches and firewalls. In the case of inventory of unauthorised and authorised devices, there should be active management (track, inventory and correction) of all hardware devices that are on the network so that it is the only authorised devices that are

The Emperor's New Clothes Essay Example | Topics and Well Written Essays - 1000 words

The Emperor's New Clothes - Essay Example (Wullschlager) The author altered the story line and changed the theme to courtly pride and intellectual vanity. (Wullschlager) Andersen lived in a time when the bourgeoisie was a class of its own. Many believe that Andersen had chosen to change the storyline and the ending of the Spanish story to make fun of the bourgeoisie and their snobbishness and hypocrisy. The satirical attempt was obvious in how Andersen described the king as someone who â€Å"wanted to be always well dressed† and â€Å"spend (sic) all his money in order to obtain† his clothes (Andersen), not caring for anyone else. Intellectual vanity was not only limited to the bourgeoisie class, however, as the old sensible minister, courtier and other officials who worked for the emperor lied to the latter about what they saw since they also did not want to be called stupid. In fact, Andersen writes â€Å"Everyone in town...were anxious to see how bad or stupid their neighbours were.† (Andersen) By mak ing the foolish emperor decide to parade his nude fat body proudly under the invisible new wardrobe because he did not want to admit his stupidity, Anderson effectively showed how much people valued their pride. The need to keep face was also evident at the end of story when, after realizing the truth, the emperor said he must bear the humiliation till the end. Also, the element of irony is present because the swindlers’ cloth which is supposed to be seen only by superior people actually made the emperor and everyone else around him who praised the new wardrobe stupid. James Finn Garner’s retelling of Andersen’s The Emperor’s New Clothes is a â€Å"politically correct version† with the author making fun of how people are trying not to be insulting, sometimes to a fault. Garner stuck to most of the storyline but changed the ending and consequently, changed the moral lesson of the fairy tale as well. Using modern language, Garner described the empero r, his kingdom and the people around him as nicely as politically correct advocates would not be expected to. Examples of such would be the tailor, who deceived the king, being decorum-impaired. The emperor was a â€Å"wisdom-challenged tyrant† who felt good about the idea of an empire that made him look good, like a â€Å"trophy wife†. (Garner) Although most of the storyline remained the same and the story was still about vanity, the author used the language of today to describe the situation, characters and feelings of the people in the story. The empire was supposed to be of people who were non-alcoholics, non-smokers and listened to country music among others. (Garner) The irony in the story is still shown in how Garner made the seemingly astute leader who believed that males were superior look inferior when he himself could not admit to the truth as to the existence of his new wardrobe. As with Andersen, Garner describes the new emperor’s body as â€Å"an ugly mass of puffy white flesh† and yet the emperor â€Å"saw this too, but pretended that he could see the beautiful, politically correct robes.† Again, Garner pokes fun at how some people already see the truth but still want to appear politically correct and say nice things to avoid being insulting. The alternate ending Garner did was to make the crowd decide on joining the nude emperor by undressing and declaring a â€Å"clothing optional† day from thereon. With this, Garner presents the issue of nudity with a thumbs-up

The Autonomic Nervous System Essay Example | Topics and Well Written Essays - 1750 words

The Autonomic Nervous System - Essay Example Each pathway comprises of a preganglionic neurone as well as a postganglionic neurone. Within the sympathetic system, the synapses between these two neurons are located near the spinal cord. On the other hand within the parasympathetic nervous system, these two neurons are located near to, or within the effector organs (Tortora & Derrickson 2009). The effects of the sympathetic and parasympathetic nervous systems normally oppose each other. They are termed as antagonists, thus is one system contracts a muscle, the other usually relaxes it. The balance between the two systems concisely regulates the involuntary activities of the organs and glands. Exceptional to note is that it is feasible to control consciously specific activities of the autonomic nervous system through training. Some examples in this include control of the anal and bladder sphincters. With regard to nerve impulse transmission process, the sympathetic nervous system stimulates effectors and produces noradrenalin as t he neurotransmitter at nerve junctions. In contrast, the parasympathetic nervous system inhibits effectors and produces acetylcholine at the nerve junction, otherwise called the synapse (Tortora & Derrickson 2009). The autonomic nervous system comprises of motor neurons which innervate smooth and cardiac muscles as well as the glands. These neurons also ensure optimal environments conditions within the systems to ensure maximum support for body activities. The neurons operate via subconscious control and have viscera as most of their effectors. Within the autonomic nervous system, the preganglionic fibers release acetylcholine as the major neurotransmitter. Postganglionic fibers release norepinephrine or acetylcholine whose effects can either be stimulatory or inhibitory. The neurotransmitter effects within the autonomic nervous system on target organs are dependent on the neurotransmitter released. Additionally, such effects are dependent on the type of receptors expressed on the e ffector organs. The divisions of the autonomic nervous system serve similar visceral organs but cause opposite effects. These divisions exemplified by parasympathetic and sympathetic categories help in maintaining homeostasis. Precisely, the sympathetic division mobilizes the body during activity while the parasympathetic division conserves the energy within the body. The role of parasympathetic division is well illustrated when a person relaxes after taking a meal. In such a circumstance, the division plays a role of keeping the energy level consumption as low as possible. As such, the heart rate, blood pressure and respiratory rates are kept at lower concentrations. However, during such circumstances, the gastrointestinal tract activity is high as a result of digestion. The skin is warm while the pupils are constricted. On the other hand, the sympathetic division is a good depiction of fight or flight system. This division allows the regulation of activities during exercises. In s uch scenarios, the system reduces the flow of blood to organs while it increases the flow of blood to muscles. Its activity is illustrated by an individual who is under a threat and as such, the heart rate increases with rapid and deep breathing. Additionally, the glucose levels in the blood are high because this important sugar is released from the liver. Furthermore, the skin is cold and sweaty while the pupils of the eyes are dilated due to alertness. Parasympathetic div

Answer Questions - Assignment Example Preventing the development of addiction in young people is essential. Family involvement is important for the families who have an addictive problem. Disclosure among a parent with an addictive problem to the child is essential as well as letting the child know that addiction is a family problem and it runs in the family, thus the child will be aware of their chances of being an addict. In schools, it is important to educate the children on the consequences that result from abusing drugs such as addiction so that the young people can be aware. Teachers and parents should be involved in childcare to discover any abnormal behaviors of the child to offer corrective measures as such behaviors result due to instances of drug abuse (Vida &Rasa, 2011). Children from alcoholic’s families have a four-ten times risk of becoming alcoholics themselves. Hereditary is a major predisposing factors to drug addiction. It is important for such parents to discuss and disclose their addiction problems to their children. Despite the problems being faced by addict parents, the child needs to be shown that they are loved. They need to know that it is not their fault that the parent has an addictive problem. The parent needs to involve the child in their own program of rehabilitation by assuring them that they will do everything to get out of the problem. It is good to discuss with the child about drug addiction as it is hereditary so that the child may avoid any instances. In so doing, young people will be aware of drug addiction thus will be very cautious not to develop an addiction problem. Often, alcoholism and other drug addictions are a family legacy. The family (parents) has the major responsibility to provide support for the alcoholic children or drug addicts. Treatment period brings the family together enhancing and opening up communication within the family structure. The parents needs to offer physical, emotional as well as

Language in Anthony and Brutus’ Speeches Essay Example for Free

Language in Anthony and Brutus’ Speeches Essay Compare and contrast Henry’s use of rhetoric to affect others in his Harfleur speeches with the effectiveness of the language in Anthony and Brutus’ speeches In Henry V, Henry uses rhetoric very effectively as he persuades the Governor at Harfleur to surrender and encourages his troops onward with his ‘Once more unto the breach’ speech. This is very similar to Anthony and Brutus of Julius Caesar as they use rhetoric to influence the ‘mob’; firstly Brutus wins the crowd over and they believe the death of Caesar is a good thing and then Anthony turns them around and they end up hating Cassius and Brutus. Henry uses rhetoric to create a number of different effects one of them being to persuade the Governor to surrender. Rhoda Koenig suggests that this scene ‘points up the character of this immature and disaffected king’, which I disagree with as I believe that this speech shows just how the King has matured as he is able to bluff his way through as his army is, really, worn and battered. This speech shows how Henry’s words are more powerful than his army, which is similar to Anthony in Julius Caesar who turns the mob into a state of madness just through the use of his oratorical skills. For example, Henry starts his speech with short, sharp sentences: â€Å"How yet resolves the governor of the/ town?† This creates an assertive beginning and one that makes Henry seem powerful and stern. This coupled with the use of a rhetorical question puts the Governor in a situation where the mercy of Henry is in his hands, as if the outcome of his men depends on his decision. This also removes the responsibility from Henry’s shoulders which is a recurring theme throughout the play. Henry also describes what the outcome could look like if the Governor doesn’t surrender: â€Å"The gates of mercy shall be all shut up.† The use of a metaphor here, ‘the gates of mercy’, refers to Henry as if once he starts the battle there’s no goi ng back. This is used to scare the Governor so that he believes Harfleur will be desecrated once the battle has begun. This, of course, is a faà §ade as Henry knows full-well that his army is worn thin and lacking in strength. This demonstrates Henry’s good leadership, as he bluffs his way through with confidence. Also, this quote contains lots of monosyllables which make it very powerful and reinforces the threat which forces the Governor to surrender. Bernard Richards raised an interesting point where he said that Shakespeare ‘wanted to show the full range of war – the glamour as well as the squalid and obscene violence.’ This interested me as throughout this speech there is talk of atrocities of war such as ‘shrieking daughters’ while elsewhere in the play we see the French think of war as glorious. This is very similar to Brutus in Julius Caesar who has to use rhetoric to convince the crowd to surrender, as they are initially angry at the conspirat ors for killing their leader. For example, he uses rhetorical questions to force the crowd to realise that the murder of Caesar will benefit them: â€Å"Who here is so base [†¦] Who here is so rude [†¦] Who is so vile [†¦] for him have I offended.† The crowd are forced to ask themselves if they would want to be slaves, for example, which they of course answer ‘no’. The use of a three-part list also emphasizes this and would allow the crowd to remember this more accurately: â€Å"Let him be Caesar!† This quote shows that Brutus’s rhetoric successfully convinces the crowd, although they appear to have missed the point as they want Brutus to be ‘the new Caesar’ and the sole leader of Rome which is what the conspirators were fighting against. It is also interesting to note that Shakespeare’s main characters usually speak in blank verse, but here Brutus speaks in prose. This is because prose is the perfect way to persuade so has a stronger affect on the crowd. It could also be argued that because he speaks to the low-life characters, they will understand prose better than blank verse. Within his speech Brutus also uses repetition which reinforces his message: â€Å"Hear me for cause [] hear.† The use of framing repetition here grabs the crowd’s attention and makes them listen. He also repeats ‘honour’ throughout his speech: â€Å"Believe me for mine honour, and have respect for mine honour.† This repetition is used to emphasize to the crowd that the conspirator’s cause was honourable and that they have done the right thing while it also serves to remind the crowd how Brutus is an honourable man, which is a similarity with Henry who also takes great care in ensuring the cause for going to war is moral. The repetition would ‘grind’ it into the crowds’ heads so that it’s almost like subliminal messaging. The repetition also shows how Brutus is still unsure himself and that he is trying to convince himself that they have done the right thing. Henry also uses rhetoric to empower his army and urge them on at Harfluer in what Hal Hinson of the Washington Post calls ‘the greatest half-time speech in human historyà ¢â‚¬â„¢. Here, Henry is forced to persuade his army that they should not retreat but attack once again: â€Å"Once more unto the breach, dear friends, once more.† Similarly to Brutus, Henry uses framing repetition to encourage his army to attack Harfleur once more. The repetition helps to reinforce the message and will stick in their minds through the battle. Also in this quote, he uses an endearing pronoun ‘friend’. This affects the army as they will feel that they are all friends of the King and will have a surge of confidence. This will help the army to conquer whatever they face, even though they have had to retreat. Interestingly, this contrast to what the Chorus says in the preceding scene as he states that the great British are invading France when really they are being forced to retreat. Henry also uses alliteration: â€Å"But when the blast of war blows in our ears.† The use of plosive alliteration here creates a powerful sound which suggests that the English army are powerful enough to defeat the French. This also shows Henry’s passion as if it’s bursting out of him as he desperately wants his men to survive as he feels guilty that the war may not have an honourable cause. Also is this speech, sibilance is used: â€Å"Stiffen the sinews.† This also creates quite an aggressive sound which would be passed onto the soldiers and make them feel aggressive and willing to fight. Henry also uses figurative language: â€Å"Let it pry [†¦] like the brass cannon.† This simile likens the mind prying to a cannon – an item associated with war – which would rile up the soldiers and also remind them that they are at war, its kill or be killed. Another simile used refers to Alexander the Great: â€Å"On, on, you noblest English [†¦] like so many Alexanders.† Here, Henry likens his army to a group of Alexander the Greats. Alexander the Great is a figure of Greek legend which states that he conquered the Persian Empire. It also says that he was often reckless with his own life and his soldiers as he believed he was indestructible. This would encourage his men and fill them with confidence as Alexander was a great warrior and Henry’s army will feel equally invincible. Shakespeare’s Elizabethan audience were very interested in Greek culture so the simile would have been more relevant and had more effect than it would on our society who have a lesser interest. Also, in this quote he addresses the ‘noblest English ’while further on he addresses the â€Å"good yeomen.† Henry directly addresses each social class as his army was compiled of a number of different classes, even nationalities. King Henry V was known for uniting people under him as he prevented a civil war between the Church and the Government and th is unity is shown in the scene between Gower, Fluellen, Jamy and MacMorris. This scene also, as James Shapiro suggests, ‘prophetically anticipates the notion of a united kingdom’. Although these nations were far from united in 1599, when the play was written as England and Ireland were at war, and some were very hostile during Henry’s reign. For example, James Shapiro criticizes that Henry says the Scots may attack yet here they are united. This would make each soldier feel important, needed and a friend of the king’s, which would, ultimately, provide the soldiers with confidence to fight, and beat, the French. Likewise, Mark Anthony in Julius Caesar also addresses his crowd individually while manipulating them until they run riot around Rome: â€Å"Friends, Romans, countrymen.† Anthony immediately begins with a three-part list which grabs his audience’s attentions and the first word used is ‘friends’. This instantly makes the crowd warm to him as he is speaking to them as equals. This is similar to Henry who calls his army the ‘noble English’ and ‘good yeomen’, while it contrasts with Brutus who says, â€Å"Romans, countrymen, and lovers†, as if ‘lovers’ is an afterthought. This may hint at why Henry and Anthony were successful at convincing their audience while Brutus failed, because Henry and Anthony allowed the audience to warm to them while Brutus did not. Another way Anthony wins his crowd over is by using repetition: â€Å"And Brutus is an honourable man.† This is repeated at regular intervals throughout his speech and each time it becomes more sarcastic. The sarcastic tone induces the crowd to question whether killing Caesar was an honourable thing. Here, in the same way as Brutus, he uses subliminal messaging; however he uses it against Brutus and to much better effect as the crowd end up rampaging across Rome. In conclusion, Henry and Anthony use rhetoric and their oratorical skills very well combining repetition, friendly language, and other techniques to persuade their respective crowds to see their way of thinking. Brutus, however, fails to convince his crowd (or is unable to deliver a speech worthy of Anthony’s) which goes to show how good Anthony’s speech is. Henry manages to convince the Governor to surrender, and convince his battered army to continue, while Anthony manages to convince an audience who love Brutus, to hunt him down. Brutus, on the other hand, cannot prevent the people of Rome from turning against him as he didn’t endear himself to the crowd.

Vygotskian Socio-Cultural Theory

Vygotskian Socio-Cultural Theory Lev Vygotsky was a psychologist that revolutionised the world with his theory on socio-cultural development. His theory of socio-cultural development centred on the notion that a child learns through adults or peers. In other words a childs cognitive development is engaged through the childs environment, this means that a child develops through interaction with other individuals. Vygotskys theory differed from other theorists theories; one of them was Piaget, a Swiss psychologist. His theory was that children learn from the inside out, this means that a child takes their own knowledge to the world (as discussed in class). Piagets theory focused on two concepts, one was the concept of assimilation, which is a cognitive process whereby new experiences and information are placed in the cognitive structure of the child. The other concept is accommodation; this is a cognitive process which refers to the resulting reconstruction that takes place when new information is taken in. Vygotsky o n the other hand believe that a childs learning takes place from the outside in, which simply means that a childs environment determines what s/he learns. In Vygotskys socio-cultural learning theory one must familiarise oneself with the concepts before we can begin to grasp the idea of theory and use it correctly. The most important feature to grasp is the zone of proximal development. The zone of proximal development is defined as the difference between what a learner can do without help and what he or she can do with help (Wikipedia; the zone of proximal development). In terms of ones understanding, the ZPD is the distance between the actual development level of a child as determined by independent problem solving and the level of potential development of a child as determined through problem solving through peer or adult interaction. The actual development of a child is the functions that have already matured and the learner understands. The potential level of development is the functions still in maturation, the understanding has not developed. The ZPD allows learners to mediate through social interaction. (Maths method: 1; Goba, B ) Vygotsky believed in three important aspects that form his theory, this is the social context, language and mediation. These three aspects are important in the sense that; the social context is the context in which learners are coming form. So they may come into the world with some kind of knowledge already instilled in them, this knowledge may not necessarily be correct. Some learners social context may enforce some kind of racism this may make the child racist. In other words children gain their knowledge through social contexts, from birth the childs social interaction depicts the kind of knowledge s/he will bring to society. Because the environment is ever changing, knowledge is ever changing. So knowledge is never static. The next aspect is language being the frontal line for the basis of this theory. If a learner cannot understand language be it mathematical, sign or the language medium, the learners knowledge cannot grow and expand because of a barrier with does not permit the development of the learners cognitive structure. Language is a way to communicate, and if language is not understood than the communication link is broken. And the last aspect is the role of mediation. In order for effective communication to take place there must be some form of mediation to aid the communication. This is where the ZPD comes into play. The learner may not understand a particular concept by way of mediation, something or someone that aids the understanding so the child goes from what they dont understand to what they can grasp. According to Vygotsky, Every function in the childs cultural development appears twice: first, on the social level, and later, on the individual level; first, between people (interpsychological) and then inside the child (intrapsychological). This applies equally to voluntary attention, to logical memory, and to the formation of concepts. All the higher functions originate as actual relationships between individuals.The socio cultural theory is then defined as a theory of learning that looks at the contribution society as made in an individuals development (psycology.about.com). It does not only focus on the learner as an individual but as the learner and cultural context on a whole. Vygotsky explained this theory in terms of language. He argued that social interaction forms this new learning through the ZPD where learners gain new language through social interaction. It outlines of a language as combining both the traditional behavioral and linguistic position of language. This theory of language can suggest that the role of the environment can produce differences in understanding. The socio-cultural theory was adopted by Jerome Bruner and made westernized, now its used all over the world. Case study: My name is Triona Pillay and Im 19 years old. I live in an Indian township. This year I did my teaching practice 220 at an Indian school which many non Indians also attend. After teaching practice 120 and all the different aspects we covered with the variations of school types we could go to, I thought Id be well equipped to handle any classroom situation with the way in which teaching practice 120 had instructed us to. However the classroom situations we encountered was different to the ones we were told to imagine. Going into teach at a school where the medium of language is English was what I perceive to be easy because that my home language and thats the language that learners should be familiar with. But that was just the beginning of my problem during my teaching practice. Being a mathematics educator was more difficult as learners couldnt grasp specific concepts. My first mistake was that learners had prior knowledge to the topics being taught, in the case of my grade: 10 class, the topic was analytical geometry. They didnt understand that when a negative is squared the number because positive. The learners taught homework was a joke and class time was for socialising. And then I had the teachers perspective who said that the learners know the work and they complain for nothing that they dont understand. Society has deemed that its generally that black learners that dont understand English and wont be able to understand what is being asked, but in this school the Indian learners got confused with the English. Simple operations like 3x=9, therefore x =3 the learners didnt understand how the answer 3 is obtained. Another thing that I found alarming was that the classrooms were plain n simple with no real posters to make the classroom a place where learners want to come. All in all my teaching practice was a real experience on how learners and adults and their environment influence their behaviour and performance. Something that I found quite fascinating was during a staff meeting and they were discussing why a particular learner behaves so horrid at school and one of the suggestions was because of the way his father treats him. Apparently the father actually hit the child in front of the teacher and walked away and a couple of other times the father sent the child with burst lips. This is not the only reason I believed for the problems Ive encountered. I believed at that school its a popularity contest were everyone wants to fit in so the brainy people stick to the smart people and the naug hty ones keep to their clan. And once you come to grade: 8 u get initiated into one of those lots. This is my personal views on the situations that occurred during my teaching practice and some of the reasons why I believe the situations occurred. Problem solving using Vygotskian socio-cultural theory: The major problem I identified during teaching practice was the lack of both mathematical language and knowledge and the ability of the learner to express their ideas or opinions in class due to the language barrier of practical English words. Firstly Id like to point out that problem cannot be solved over night. It requires gradual input from both the teachers and the learners. My first plan of action in my class is to encourage reading in my class. Maybe I can suggest that the school put in place 30 minutes of readings in the morning. The department of education does send schools educational newspapers that they can give to learners to read. The more the learners read the more the learners build up their vocabulary. My colleagues and I can introduce 10 new, interesting and exciting words that the learners can use during the week, at school to replace the mundane words that they use all the time. Using Vygotskys principles will take some patients from both the learners and the teach ers especially for teachers who have been teaching for 20 plus years, many people are not subjected to change. The next step as a maths teacher is to build on prior mathematical knowledge and motivate the learners, so that if they understand the basics the rest will follow. I could also encourage the learners with higher marks to help those who are lacking behind. We can also have extra classes during the break to enhance their mathematics skills. This is a great idea as learners can stay out of trouble and get work done. The learners need proper scaffolding and we as teachers need to provide the necessary guidance. Vygotsky introduced that a child learns through his or her environment so if the child is taught in an environment conducive to learning the child may enjoy coming to that classroom and learn something. I could suggest to learners that they join peers who going to improve their rather than influence them negatively. The next idea is a tricky one because from the time I was in school I noticed teachers who tried to reach out to learners whose environment at home is unstable, shot down by parents who think they know it all and believe that the teacher is meddlesome and should mind their own business. To have a parent meeting is sometimes futile because the good learners parents only end up coming and the parents you need to see dont. According to Vygotsky in a classroom situation we the teachers are the mediator, we should therefore be care how we give off information because learners are young and can sometimes misinterpret what we say. So when teaching, as a future teacher I need to make sure Im clear and precise. Concepts need to be to the point and one should not beat around the bush. I could also introduce the concept of motivation in my class. If I aid the learners in their learning and even in their attempts in learning I will be able to take them from the known to the unknown. Using motivation learners will want to try and work harder and by this get a better use of both the medium of language and the mathematical language as a whole. The classroom environment is another are that I can encourage learners development. If I make the classroom environment a fun way to learn and learners wont get laughed at and shot down for trying. Children learn from their mistakes so if I encourage them and they give the wrong answer and we correct it, they wont forget. In conclusion my belief is that Lev Vygotsky was a psychologist whose theory greatly influenced the world. His socio-cultural theory if understood properly can aid both teachers and learners effectively to achieve top results. I also believe that parents should try their best to give their children the best social contexts and keep them away from negative influences. As a future teacher Ive learnt a lot from Vygotskys theory and will use this theory fruitfully when I start teaching.

Comparing the Puritan Setting in Scarlet Letter and Ministers Black Veil :: comparison compare contrast essays

Impact of the Puritan Setting Upon the Characters in The Scarlet Letter and The Minister's Black Veil This essay will examine the thematic relevance to the Puritan setting and its impact upon the characters and their development in both "The Scarlet Letter" and the short story, "The Minister's Black Veil." These two texts detail an accurate portrayal of what I assume the Puritan community to represent. This is partly because of the Puritan background within the works, but also considering that the main characters of these are deeply rooted within the Puritan faith and are, in different ways, in the public eye and are under separate scrutiny as a result of such. Mr. Hooper, being a minister, is considered a beacon and an exemplar of faith and righteousness in his community. One bright Sunday morning, Reverend Hooper dons a black veil to his congregation and lectures on sin and its appearance, or lack thereof. His congregation is outraged but intrigued by his use of the symbolic sheath. Since his sermon focuses on the "secret sin" of his parishoners and the entire community, they are d rawn to assume that Mr. Hooper, himself, carries with his a "secret sin" which he is hiding from underneath his veil. Now Hawthorne titles this short story as a parable which leads one to conclude that the veil is used a not only a symbol of "secret sin" but a paradox. His congregation is so concerned and obsessed with his personal sins that they forget about their own; this was the intent of Mr. Hooper's veil: to cause them to reflect upon their own spiritual status and to confess their sins. But the Puritans, notorious for their pride within practice and fallacy within faith, ignore this allegorical costume and sensationalize his message. Because, after all, Mr. Hooper must be hiding SOMETHING underneath that veil of his... The second character under scrutiny by their community and this English major is Hester Prynne, a young woman forced to don a scarlet letter "A" to signify to herself and to her community that she is a marked sinner. The letter, much like the veil, is an exterior symbol of appearance which is a popular device of Hawthorne; the outward appearance is an important aspect of the P uritan faith in that it reflects upon the interior climate. Interestingly, these symbols and their stewards are instituted for the benefit of the community.

Culture and Identity Essay -- Cultural Identity Essays

Culture and Identity Culture and identity could have many different definitions. Culture to me is what made you the person that you are today. The background and history of a person that is the reason of who they are and what they stand for. Identity to me is the certain characteristics that belong to a person that makes them different from everyone else on this planet. The world with no culture or a lack of identity would be a rather boring place. Identity and culture are what makes this world an interesting place, there is a distinct relationship between identity and culture and one without the other they could not exists. In the essay "Real Indians Eat Jell-O" by Laurie Carlson, it seems that she has trouble finding her own identity and culture. Carlson a native american living in a trailer park in Montana wants to know more of her culture to try to give herself an identity. Carlson states "Indian kids are supposed to live in wide open spaces, in deserts or forests. They have horses and coyotes and wise grandparents" (Carlson par. 2). Instead of making her own identity and learning about her culture now, she wants have the identity of someone else, she wants the identity of Indians from hundreds and hundreds of years ago. She looks to her grandmother for culture and does not like what her grandmother has to say, Carlson wants to hear stories of beadwork and tales of coyotes while her grandmother while her grandmother taps her "primrose passion" colored nails to the song on the radio and tells her "Honey, be yourself"(Carlson par. 7). Personally that is the best answer anyone could give a child who is looking to make an identity for themselves, because an identity is who you are and who you are is everything. Also Carls... ...more successful than my parents just like they were more successful then my grandparents and like my grandparents were more successful then my great-grandparents. My community culture growing up has given me the hardworking, go getting attitude that I need in life to grow up to be a successful person in this world. Culture and identity have a very close knit relationship between them. A persons culture helps them to determine their identity in life. Without knowing your own culture, weather it be a poor indian growing up in a trailer park or a rich white boy growing up in a huge house, your identity would be very hard to determine. A persons culture is the main part of a persons identity, and without knowing your culture it would be hard to figure out ones identity. Works Cited Carlson, Laurie. "Real Indians Eat Jell-O".

Investigation in Microtubule Dynamic Instability

Title: Investigation in microtubule dynamic instability Introduction Microtubules are important for maintaining cell structure, intracellular transport, formation of mitotic spindle, as well as other cellular processes. Investigation of dynamics of microtubule assembly and disassembly allow us to understand the malfunction of mitotic spindle formation or other cellular processes. This experiment is divided into two parts; we are going to find out the critical parameters for achieving greatest average length of microtubules in part one and achieving the greatest number of microtubules in part two.Principle In this experiment, we used a simulation programme to explore how various factors change the way microtubules grow out from centrosome, and the shrink back. Growth rate, shrink rate, catastrophe rate, rescue rate, release rate, minus end end depolymerization rate, nucleation rate and nucleation site are the factors we can adjust to see how them affects the average length and number of microtubules. The simulation time acceleration is set to 5x real time. Each time a parameter is varied and others are controlled factors.The record is taken when the simulation has reached steady state and graphs are plotted.

When polymerization is proceeding rapidly, tubulin molecules add to the end of the microtubule faster that the GTP they carry is hydrolyzed, and the microtubule growth. [1] Varied the growth rate and kept other factors constant, the average length of microtubules should always increase. However, the average length of microtubules rises as growth rate increase from 0. 14 to 0. 22Â µm/sec and stop increasing at 0. 2Â µm/sec. It tends to level off rather than increase at 0. 22Â µm/sec. It means the growth rate is no longer the limiting factor. Some factors other than growth rate, may be the rescue rate, limited the increase of the average length. Rescue rate is the rate at which a shrinking microtubule switches to growing state. We assume the greatest rescue rate, the more the microtubules undergo polymerization. So that the proportion of growing microtubules would increase and the average length rise. Instead of increase, the average length of microtubules drops from 0. 084 to 0. 104Â µm/sec.Increase the rescue rate may trigger the mechanism that lowers the average length of microtubules. It remains at around 20Â µm from 0. 104 to 0. 164Â µm/sec means that that there is no correlation between rescue rate and the average length beyond a point among 0. 084 and 0. 104Â µm/sec.

The nucleation site acts as a preexisting microtubule structure for -tubulin dimers assembly. [1] We assume the more the nucleation site, the more the microtubules present. According to table3, the number of microtubules is always increasing with the number of nucleation site. There is no sign of level off or decline of the curve.It always is the limiting factor of the number of microtubules. The nucleation rate is the rate at which new microtubules are nucleated at the centrosome. The number of microtubules should be raised if the nucleation rate increase since new microtubules generated. Indeed, the number of microtubules is raised as the nucleation rate increased. From 0. 02 to 0. 06Â µm/sec, the increase of microtubules is sharp and starts to slow down afterward. The trend shows that the curve would level off at certain level eventually. It means there are some factors other than nucleation rate control the number of microtubules.The number of nucleation site may be the limiting factor as all nucleation sites are occupied by the microtubules, so that n o new microtubules generated. Limitations In actual cell, the number of tubulin dimer is limited. This factor is not shown in this simulation programme. The temperature and the pH may affect the configuration and polymerization of the microtubules. There are some microtubules not attached to the centrosome, but present in cilia and flagella. It is not clearly stated by the simulation programme whether these microtubules is counted. ConclusionsBesides the growth rate, there are other limiting factors controlling the average length of microtubules. We cannot achieve the greast average length of microtubules by consider growth rate is the only factor. We found that we should keep the rescue rate at 0. 084Â µm/sec or below. Also, more information about the rescue rate below 0. 084Â µm/sec should be obtained. Both nucleation site and nucleation rate are the factors controlling the number of microtubules. But the nucleation site is more critical than the nucleation site. The above show the nucleation rate is restricted by other factors but the nucleation sites does not.We should examine another set of data by varying the nucleation rate with more nucleation site. If the plateau of new obtain curve is above the original curve, nucleation site is limiting factor of the number of microtubules. Similar experiment should be established with different combination of parameters in order to obtain the best curve. In short, there is not enough information for us to draw conclusion for how to achieve the greatest average length and greatest number of microtubules unless we obtain more data. Reference 1.
