Relationship Between Parent and Child - Essay Example Julie, as known by her father, started out as a â€Å"warm, sensitive, sweet child and very easy going† child. She was a bubbly little girl who was curious and creative and had a very positive disposition. Her profile was painted by her father with loving words, projecting an ideal daughter that brought her parents much joy and pride. This kind of personality usually results from having a secure attachment with her parents while growing up. In the first few years of life, a child with a secure attachment can learn how to balance separation and reunion. She is unafraid when she gets separated from her parents, trusting that they will be back for her. On the other hand a child with an insecure attachment to his mother manifests panic, anger and a desperate search for her, thinking that she will never come back. When the mother returns, a host of responses may be observed of the child. Some children would be delighted and warmly embrace the parent; others would appear to be indif ferent, withdrawn, hostile, uncertain or confused. The kind of response the child had led the psychological observers to develop the attachment categories of secure, insecure-avoidant, insecure-resistant and disorganized. Schore (2001) claim that infants’ attachment experiences are stored in the early maturing right hemisphere of their brain, which have long term effects on how they cope with stress in the future. Hence, it is suffice to say that attachment is crucial to the emotional development of the child, and this is reflected in Julie’s personality as a child.... He allowed them to make mistakes because from these, they learn too. He claims, â€Å"I never confronted the children directly when they made a mistake, I but always guided them until they got it right. I wanted to enrich their environment in order to boost their self-esteem and their confidence.† This reflects Vygotsky’s (1978) theory of learning where it is believed that children learn within a ‘zone of proximal development’ (ZPD) or the distance between a child’s independent problem-solving level and that obtained under adult guidance or in collaboration with more capable peers (Wertsch, 1985). It is the space between what a child can do by himself and a more challenging level that he can achieve with help from someone. In the case of Julie and her sister, their parents provided ‘scaffolds’ or temporary supports in the process of learning which are gradually taken away when the children are already capable of learning without them. Mo st common conflicts/disagreements/challenges between parent and child Anthony remembers Julie as a very well-behaved child so there weren’t much conflicts or disagreements between them. The only challenging thing that he remembers is her insistence to choose her own clothes every morning, careful not to repeat outfits within close periods of time. If she had no choice but to wear pants two days in a row due to laundry problems, she would throw a fit. â€Å"That is the only time that I can remember when Julie would get mad, scream and cry and go to her room†. Otherwise, it was smooth sailing with Julie because she was quite mature for her age. The misbehaviour that Julie displayed was a manifestation of her growing up into a young lady who wants to prove that she is capable of making her own

Roma People And The European Union Politics Essay

Roma People And The European Union Politics Essay The term Roma refers to a variety of groups of people who describe themselves as Roma, Gypsies, Travellers, Manouches, Ashkali, Sinti, as well as other titles. For the purpose of this paper, we will use of the term Roma to describe the group in question. This is in no way intended to downplay the great diversity within the many different Romani groups and related communities, and it is not intended to promote stereotypes. Our basic question is what is the status of the Roma people today, within the context of the European Union? For millennia, the Roma have been an integral part of European civilisation. Today, with an estimated population of 10-12 million people, Roma are the biggest ethnic minority in Europe; Roma communities are present in all 27 EU Member States. And in contemporary times, most Roma are EU citizens. An issues is that their situation is characterised by persistent discrimination and social exclusion. Thus, Roma are very exposed to the risks of poverty, unemployment, stereotypes and social prejudice. Its vital to understand that the Roma population is heterogeneous. Following the elimination of traditional labor activities and of nomadic lifestyles in some Member States, urban migration, but also migration from Eastern Europe to the western EU states, there have been a lot of changes affecting the Roma people. However, there is a very big gap between the living conditions (in the fields of health, education, labor and housing) of the Roma and the majority population. And a concentrated effort toward EUs integrated policy towards the Roma is needed, preferably a multidisciplinary one, dealing with the problem from multiple angles, not just from an economic of sociological point of view, and also one whose results have to be quantifiable, state-wide but also centrally. This is our hypothesis. Legal Framework in the EU The European Union has established a strong legal anti-discrimination framework; the most important documents on the issue consist of Article 13 of the Treaty establishing the European Community, Council Directive 2000/43/EC on Racial Equality and the Council Directive 2000/78/EC, that establishes a general framework for equal treatment in employment and occupation. The European Union also has a strong legal framework dealing with Roma discrimination, that is based, among others, on article 13 of the Treaty of the European Community, the Directive 2000/43/EC on racial equality and the Directive 2000/78/EC concerning the prohibition of discrimination in employment and vocational training. Its important to note however that it is the duty of the Member States to translate these Directives into their own national legislations.   The European Commissions mandate also includes stimulating the use of EU Structural Funds by EU Member States for supporting Roma inclusion.  This process is supported by the EURoma network, composed of representatives from 12 Member States,  whose goal is to promote the use of Structural Funds in order to enhance the effectiveness of policies targeting the Roma and to promote their social inclusion.   Roma people in Romania According to official data, Roma population in Romania included, according to the 2002 census, 535,250 people, of which 325,000 people (60%) lived in rural areas. Roma population is, numerically speaking, the second ethnic minority group in Romania, after the Hungarians. However, these census numbers might or might not reflect reality, for there are probably more Roma who havent been accounted for because they refused to participate in the census or might have avoided stating their nationality. According to a study by the National Agency for Roma, the socio-economic situation of Roma ethnicity remains still quite difficult: Roma score on a high level of poverty. Roma communities are affected by various problems: high levels of unemployment (28%), low income, low educational and vocational training (with visible effects in the labor market participation), improper living conditions and limited access to public services. Many Roma are working as day laborers, thus without having a stable source of income. According to OSI (Open Society Institute) research conducted in 2007, 4.9 percent of Roma people in Romania lacked a birth certificate. Among nonà ¢Ã¢â€š ¬Ã¢â‚¬ËœRoma citizens, less than 1 percent lacked a birth certificate. Similarly, surveys in 2007 and 2008 indicated that between 1.9 and 6 percent of Roma lacked identity cards, compared to 1.5 percent of nonà ¢Ã¢â€š ¬Ã¢â‚¬ËœRoma. The lack of identity documents leads to exclusion from participating in elections, receiving social benefits, accessing health insurance, securing property documents, and participating in the labor market. Another survey, conducted by the ICCV (Institutul de Cercetare a Calitatii Vietii), points out that the proportion of illiterates among Roma is disturbing: more than one third of the Roma (38.6%) are functionally illiterate, 19% of men and 27% of mature women only attended one school year. 18% of Roma children aged between 7 and 16 years have never been to school. Among the conclusions of the study are the following: Roma population categorically refuse to be a part of the education system. The problem is that the Roma population lives, usually in secluded and / or notorious neighborhoods, and schools located in these areas, where Roma children might study, have inferior learning conditions. NGOs and the media report that discrimination by teachers and other students against Romani students served as an additional disincentive for Romani children to complete their studies. However, other Roma are largely or fully integrated into society. Scholarships in schools and universities were created for Roma by the state creating positive discrimination whose impact on improving integration in Romania remains to be seen. On the downside again, in schools where students are predominantly Roma, repeater rates reach 11.3%, almost three times higher than the national average. Because of the low quality level of the school, almost 20% of Roma students enrolled in the fourth grade are functionally illiterate, according to the ICCV. The EU, Romania included, has launched a program entitled Decade of Roma Inclusion to combat this and other problems. Roma situation differs from country to country, but integration problems remain in developed countries. A report by the European Roma Rights Center (ERRC) emphasizes that, in 2005, the Roma in France for example, counting around 500,000 individuals are the target of dramatic levels of discrimination. The report notes that civil, political, social and economic community are frequently violated and concluded that the authorities fail integration of minorities in the Hexagon (France). The most important communities of Roma live in Central and Eastern Europe, but, similariy to Romanias case (where the official 2002 census claims numbers of 535,000, while a EU report dating from 2004 says there are 1.8 million Roma) their number varies between official censuses and unofficial estimates: Czech Republic has between 11,000- 200,000 Roma, Slovakia, between 95,000- 550,000, Hungary, between 200,000- 600,000, and European reports on this minority are often negative. In each of the three of the EU countries mentioned above, unemployment among Roma reaches 75% -80%; when they have access to education, most often the children study in special schools and the wider community is a victim of racial prejudice coming from the majority population, according to Amnesty International. EU Strategy for Roma integration The European Commission has set up a programme to tackle the main difficulties involved in the integration of Roma people. There are EU funds available to help, and countries are encouraged to make greater use of them on a national level. To this effect, one important tool is the European Social Fund, which currently stands at around 12 billion Euros and amounts to 10% of the EUs budget. The purpose of the fund is to provide support for projects that seek to improve social cohesion in the Union. The second European Roma summit, was being held at the beginning of April 2010- on the International Roma Day, and was set-up as a forum to discuss the Commissions new strategy and to renew commitments. Representatives of EU institutions, EU countries and civil society organisations, including Roma groups, have participated in the conference and also present were World Bank Director Theodore Ahlers and the investment banker and philanthropist George Soros. The direct involvement of Roma organisations and representatives was a key feature of the event. The agenda included the implementation of rules against discrimination and racism by member countries of EU. Concerning this, the Commission had taken legal action against 24 EU countries which have not fulfilled their obligations in this respect and for 12 of these cases, the proceedings are ongoing. The focus shifted in the EU in 2009 from an analysis of the problems to an exploration of how existing instruments could be made more effective and how the situation of the Roma could be addressed more explicitly across a broad range of policies, including employment, social inclusion, health, education, housing, youth and culture. But the enforcement and development of specific EU legislation in the areas of non-discrimination, freedom of movement and anti-racism has continued. The European Platform for Roma inclusion- composed of key players in Roma inclusion from EU institutions, international organisations, Member States governments and civil society, was launched in April 2009 to exchange good practice and experience and to stimulate cooperation among its participants, with a clearly stated objective: to increase the coherence and effectiveness of the parallel policy processes at national, European and international level with a view to creating synergies. Most Member States report a stronger focus on internal coordination and on involving the Roma communities. Some Member States have begun to use the opportunities of complex programming and combined cohesion policy instruments. Among the findings of the forum, it seems that Member States want to mainstream Roma issues and to use mutual learning in order to explore how to improve their current initiatives on desegregation and on access in the areas of education, employment and basic social services. Another new effort of The European Commission deals with the implementation of a pilot project on Roma inclusion (5 million Euros for 2010-2012), initiated by the European Parliament, addressing early childhood education, self-employment through micro-credit, and public awareness particularly in countries with high Roma populations. The pilot project will also explore methods for data collection and counterfactual evaluation to assess the impact of the interventions in these three fields. Specific problems concerning the workforce As a fact, working age Roma lack sufficient human capital. Apart from barriers such as labor market discrimination still affecting them, the vast majority of working age Roma lacks the necessary qualifications to participate effectively in the labor market. The next figures will portray the cases of 3 member states, Bulgaria, the Czech Republic and Romania, and also a non EU state, Serbia, in order to get a grasp of how serious the educational problems are among various European Roma communities. Note: Data included in figures 1, 2 ,3 and 4 comes from the World Bank. This is seen dramatically in Figure 1, which shows the proportion of working-age Roma that have completed at least some secondary education or more. Only 1 in 5 Roma of working age in the Czech Republic and as few as 1 in 8 in Bulgaria, Romania and Serbia are equipped with these necessary education skill levels. Working age members of the majority populations in these countries are 4 to 6 times more likely to have these educational qualifications. Figure 3 shows the average monthly net income that employed Roma earn compared to that of the majority population. Employed Roma earn 31% less in Bulgaria, 48% less in Serbia, 55% less in Romania, and 58% less in the Czech Republic. Specific problems concerning demographics and education The health situation of the Roma conditions their life expectancy and their demographics are different from the european average. The European Roma population is significantly younger than the overall population (an average of 25.1 years old in seven Member States, compared to 40.24 years in the whole EU; 62.38 percent of the Roma population is under 29 years old, compared to 34.98 percent in the EU-27). There is no official information on the average life expectancy of Roma, but this is expected to be significantly lower than the overall EU population (which is around 63 years old in Romania) The child dependency index is 57.77 compared to 23.33 in the EU, while the elderly dependency index reaches 4.11, much lower than the EU of 24.93. There is also a gradual decline in birth rates among Roma, however, the replacement index (reflecting the number of people with ages between 15 and 39 for every 100 people aged 40 to 64) remains significantly higher among Roma (231) than for the overall population (101). As we have seen from the figures above, Roma citizens in some Member States influence the demographic pyramid in a specific manner. Educational systems are selective and, despite efforts by Member States to overcome segregation, a great deal of the systems that have been ostensibly designed to combat segregation are often used in practice to increase disparities between social groups and disadvantage the poor profoundly, especially in the case of Roma. There is a constant need of specific educational policies to address Roma families and also policies that encourage active participation. Although the proportion of young Roma enrolled in education and higher education systems has largely increased in some Member States, their level of qualification is still below the EU average. However, in the absence of formal qualifications, the position of Roma in the labor market can be improved by creating a system of recognition of practical skills. Indeed, Figure 6 shows that among Roma who completed secondary education the average earnings are much higher than the average earnings among Roma who completed primary education: 83% higher in Bulgaria, 110% higher in the Czech Republic, 144% higher in Romania, and 52% higher in Serbia. Romanias efforts aimed towards the Roma through structural funds Surprisingly, there is a great deal of implication concerning this matter with the local, Romanian authorities, and a lot o projects concerning Roma and their social integration are on their way. Most projects are co-funded by the European Structural Funds, are managed centrally and focus primarily on education (including early childcare), vocational and professional training, labour market insertion and social inclusion. According to the information provided by the Romanian Managing Authority, a total of 11 projects are being or will be implemented multiregionally or statewide with an aggregate budget of 37,819,853 Euros and are planned to benefit 61,634 Roma men and women. Most projects are short-to-medium-term (2-3 years). We can note that 6 major projects (employment and early education) are directly managed by the National Roma Agency. Our hope it that perhaps these efforts will actually wield some quantifiable results. Figure 5 source: EURoma report- Roma and the Structural Funds There are currently several integrated projects that rank as highly important. First, a transnational pilot project, Together on the labour market, is managed by the National Roma Agency is being implemented in 8 cities, in partnership with the Fundacià ³n Secretariado Gitano from Spain as transnational partner during the period 2008-2010. In the following period, 2010-2013, the project aims to be expanded nationwide. At a cost of 4,908,749 Euros for a period of two years, the project has ambitious aims: to benefit 6,670 Roma women and men through personalised support for labour insertion, vocational training adapted to the demand of the Romanian labour market. With a budget of 4,770,000 Euros, another employment activation project, Strategic steps for improving access to education for Roma children, presents ambitious outcomes and outputs: to increase the qualification on the labour market of 2,000 persons, including 1,000 Roma, the development of social economy structures, the increase of job opportunities addressed to vulnerable groups, the establishment of 8 Regional Centres to supporting social economy structures, the creation of 8 Regional Partnerships, and the development of 80 social economy projects. Within the education field, the All in kindergarten, all in the first grade. Integrated programmes for increasing the access to education and the educational level of the children within under-privileged communities, mainly Roma, during 2008-2009 project, is managed by the central government with a budget of 5,000,000 Euros. Although no data is yet available on its results, it had some ambitious and specific targets. The general objective of the project is to prevent and correct early school leaving for children aged 5 to 8 within 420 disadvantaged communities (a high proportion of them being Roma children). It seeks to increase access to pre-school and school education for 8,000 children within disadvantaged communities, mainly Roma, trough participation in Summer kindergarten and School after school educational programmes. Its potential outputs are ambitious: A 75% decrease in school dropout rate for pupils in the first grade belonging to the 420 disadvantaged communities; 6,000 Ro ma children benefiting from the school-after-school programme and 10,000 Roma parents receiving counseling regarding child education. Three other projects target pre-school education. Two are managed respectively by the Amare Rromentza Roma Centre and the National Agency for the Roma, with more than 4,000 combined beneficiaries. The third, titled Strategic steps for improving access to education for Roma children is managed by Romani CRISS and will have as a general objective the reduction of early school leaving risk among Roma pupils. With a budget of 4,872,060 Euros, it will develop desegregation plans within 90 schools from 4 regions of the country -North-West, Centre, South-East and Bucharest-Ilfov over three years, including intercultural training for 150 teaching staff and awareness-raising initiatives regarding the benefits of education to 20,000 planned Roma beneficiaries. Finally, an integrated project, Education of Roma children- the way to a guaranteed employment, is being managed by the National Roma Agency and implemented for three years (no exact dates provided). It aims to increase of the educational level of the Roma children from rural and urban areas nationwide and the development of human resources. With a budget of 4,943,831 Euros and targeting 4,800 beneficiaries (50% women), it could help to find ways to articulate education and employment policies through effective local implementation of equal opportunity and desegregation measures, and if it demonstrates long-term sustainability. Economic costs of Roma Exclusion: As expected, the fact that Roma people sit on the margins of society leads to some macroeconomic consequences. These consequences have been thoroughly analized and documented in a recent, 2010 report by The World Bank. Note that some of the issues presented in the report have surfaced in the previous chapters of this paper. A summary of the findings is presented in the following table: Figure x: The economic costs of Roma Exclusion The vast majority of working-age Roma lack sufficient education to participate successfully in the labor market. As a result, European countries are losing hundreds of millions of Euros annually in productivity and in fiscal contributions to the governments. Lower bound estimates of annual productivity losses range from 367 million Euro in the Czech Republic, 526 million Euro in Bulgaria, to 887 million Euro in Romania. Lower bound annual fiscal losses range from 202 million Euro in Romania, 233 million Euro in the Czech Republic, and 370 million Euros in Bulgaria. Toward inclusive growth: bridging the education gap is also the economically smart choice to make Better educated Roma can expect much higher earnings. Compared to Roma with primary education, Roma who complete secondary education can expect to earn 83% more in Bulgaria, 110% more in the Czech Republic, 144% more in Romania. The annual fiscal gains from bridging the employment gap are much higher than the total cost of investing in public education for all Roma children; by a factor of 7.7 for Bulgaria, 7.4 times for the Czech Republic, 2.4 times in Romania. The share of Roma among the working-age populations will rise as majority populations in Eastern and Central Europe are aging rapidly. Equal labor participation among the Roma is essential to shoulder the nationally rising costs of pensions, health and other costs of aging. source: The economic costs of Roma exclusion, World Bank Report, April 2010. Conclusions We consider that Roma are mostly discriminated because of a certain lack of education, but also because they are sometimes perceived as social outcasts. And this is sometimes a matter of choice, even tradition, which makes this a very tough area to cover and improve. Education is a milestone to consider, and perhaps the key to solving a lot of Roma related problems. We have seen that there are trumendeos efforts on a local but also European level, which we believe is a positive sign. The use of structural funds could be a very powerful tool when used properly. While targeting Roma education might lead us to certain cultural barries, we have to do our best to understand these limitations and figure out a way to please both parties. There are a lot of opportunities and advantages what will come with a better integration of the Roma people, and some steps have been taken into this direction, both socially and economically. However, there is one problem that should be noted. The issue of results, and more specifically, how do we make the efforts quantifiable? We see a lot of projects through structural funds in Romania, but we should also bear in mind their specific results and goals. The centralisation of these results should be a priority, otherwise they risk getting by unnoticed. Have the goals been achieved? They the programmes succesful, but just how much? How can they be improved so they reach the broader audience rather than smaller groups?

The Work of Cot and Renoir :: essays research papers

The nineteenth century produced a great number of art works from such artists as Pierre August Cot and Pierre-Auguste Renoir. Two major themes in these works include images fabricated from the real world and mirror images of everyday situations in life. Cot produced a pair of star struck lovers sharing a moment together in a hidden dugout enclosed by trees and shrubs while Renior recreated a midsummer’s day with a family enjoying an outing downtown. Each of these painting possesses an iconography in which the artist has contrived within his mind as the main theme to his work. This image is not intended to influence the viewer’s individual observation, but to embellish the work’s particular symbolism. Cot was a wonderfully gifted painter who applied remarkable use of proportional status when creating a two-dimensional painting. The only disadvantage about Cot is that his name is not well known. When this occurs, an artist and his work lack the media voice it needs to posses in order to advance among the inflections of those who do the observing. Therefore personal information is difficult to come across. His work can be classified under representational art. This form of art uses natural images that look very much like images in the natural world. His portfolio of artwork has not received the noteworthy recognition it so deserves. The Storm, created in 1880, is his only painting to have received praise from the world of art. To showcase another masterpiece completed by Cot, I chose to compare and contrast the composition of Le Printemps . This was also created in the same era and was influenced by images fabricated from the real world. The composition of this painting is quite complete; it includes actual lines, organic shapes, and the illusion of light.   Ã‚  Ã‚  Ã‚  Ã‚  Le Printemps grants the subconscious mind to drift into a fantasy-like state and the illusion of mortality merges with the illusion of realism. Cot portrays the young couple on a swing as his major element. The entire picture is based upon this element and with actual lines, the ropes of the swing and the immediate surrounding environment are defined as background major elements. Two large ropes are attached to a small wooden plank, containing the man and woman. Indentations can be seen where the man is holding on and the illusion of movement is understood. For the environmental elements, the large tree symbolizes the relationship it has with the swing as well as the direction in which the couple is swaying.

Beowulf Essay Essay

Throughout history there have been many stories about men who were considered to be a â€Å"hero. † The definition of a hero has changed throughout the evolution of society. In the days of Beowulf and the Vikings, a hero was a man who was strong, courageous, and willing to protect his land and provide for his people. In today’s world, a hero is someone who is known for their selflessness and bravery. Beowulf is described as an epic hero before he even speaks a word in the story. He is described as â€Å"mightiest man on earth†, â€Å"the noble warrior†, and â€Å"the man whose name was known for courage, the Great leader. † These opening quotes about Beowulf alone make it seem like he was not only a great warrior and leader, but also a great hero. Beowulf displays the most common traits of a hero throughout his journeys. A hero needs to display bravery, courage, loyalty, dedication and determination to be considered a â€Å"hero†. According to www. dictionary. com the definition of loyalty is having a strong feeling of support or allegiance to someone or something. Throughout the entire story of Beowulf he stays loyal to the people of Geatland. From the beginning of the story Beowulf showed loyalty when he sailed to Geatland for King Hrothgar just to repay the debt of Hrothgar saving his father in the earlier years. Beowulf pledged his allegiance to Hrothgar when he needed his most because he believes in the hero characteristic of loyalty to someone or something with importance to you. Even after Beowulf kills Grendel and has in some way repaid his debt to Hrothgar he still stays in Geatland and fights Grendel’s mother and at the end of the story he fights the dragon for the good of his people. Beowulf remained loyal to Hrothgar until he became king and then he stayed loyal to his people for the remaining years of his life. Throughout all of Beowulf’s life he has been dedicated to being remembered and to live on even after he has died. Beowulf did not want any type of reward or prize for doing the things he does, all he wanted was to have fame and be remembered by people. This dedication lead him into many difficult battles that risked his livelihood. This dedication to fame leads him through the battle with Grendel, Grendel’s mom, and the dragon. All of these battles were fought so Beowulf’s name would live on and he could die a â€Å"hero† to his people. The most important characteristic of a hero is bravery. Beowulf displays how much bravery he actually has in three different battles. The first battle was his main reason for going to Geatland, to stop the man eating monster Grendel. Grendel is feared by all of the Danes but Beowulf was eager to meet Grendel in battle. Grendel had killed many of Danes before Beowulf arrived yet still Beowulf shows no fear. Also Beowulf tells the men in the mead hall how he will not fight Grendel with any type of sword or knife because the monster doesn’t use anything like that either. Even though Beowulf makes the fight an even one for his own personal reasons this action displays an immense amount of bravery. Beowulf kills the monster with his bare hands and restores peace to the Danes even if only for a little while. Courage also is an important characteristic of Beowulf. After killing Grendel with his bare hands this is a courageous act in itself, Beowulf is summoned to kill Grendel’s mothers. It took courage just to be on the journey to get to Grendel’s mother. Beowulf ventures into her lake home eager to meet her in battle just as he was with Grendel. Despite the fact that the lake is filled with creatures and evil things Beowulf shows no hesitation in going straight in by himself to fight Grendel’s mother. Once inside Grendel’s mother senses Beowulf and immediately drags him into her home. It looks like Beowulf is about to be killed when he takes a sword and cuts the throat of Grendel’s mother, defeating her. Beowulf re-surfaces and is greeted by the remaining men outside the lake. This journey into the lake and into Grendel’s Mother’s home was nothing short of courage. Even after Beowulf is king for many years he never loses his courage. When Beowulf is an old warrior his land is attacked by a sleeping dragon awoken by treasure being stolen from its cave. Beowulf immediately went on a journey to slay this dragon. It was said that no man had entered into the dragons cave and lived. Even with information known Beowulf still lead his followers into the cave to fight this dragon. Although the dragon takes Beowulf’s life, this journey is extremely courageous. Beowulf helped in the killing of this dragon and in return gave his life just so his people would be safe. It could be argued that Beowulf is not hero because heroes don’t gloat about their fights or accomplishments. Although Beowulf tells people he is the strongest person alive and he bragged about his accomplishments, it doesn’t take away from the fact that he displayed more than one characteristic of a hero. His bravery and courageousness are more prominent in his life than his gloating. Also it could be argued that heroes don’t accept things such as money or gold in return for doing a heroic act. Beowulf did accept gold from the Danes but during this time period it was a common gift for someone like Beowulf to receive gifts and gold. In some cases it might have even been seen as rude or disrespectful for Beowulf not to accept their gold. These two arguments have valid points but overall when you compare the heroic traits to the non-heroic traits of Beowulf the heroic traits outnumber the non-heroic traits. All in all Beowulf was a great man who led a great life full of accomplishments and accomplished missions. Everything he did was for a purpose that benefitted not only himself but more importantly the people he was loyal to and that were loyal to him. Throughout the story of Beowulf he has proven himself to be not only a great man but also a hero. Beowulf fought three non-human opponents and still with no fear or doubt he rose above and defeated all three of his opponents. Beowulf is the definition of what a hero should be like and he does a great job of displaying the traits one needs to have in order to be considered a hero.

Abrasive Water Jet Cutting Report Engineering Essay

Up until about the mid twentieth Century the bulk of production relied on â€Å" two traditional procedures of forming and machining ( Tlusty, 2000 ) . Forming is the procedure of altering the form of the whole work piece, whereas machining removes merely certain, and desired countries. Whilst these cardinal procedures still form the really anchor of contemporary production, there has besides been the demand for new procedures to be developed. The traditional procedures, as highlighted above, have a figure of built-in restrictions which limit their application to industry. In the instance of conventional machining procedures, a crisp film editing tool is used to organize a bit from the work by shear distortion. This consequences in the formation of high forces together with the corresponding mechanical energies. Together with this are a figure of extra jobs that can originate. Due to sum of energy required to transport out the operation, a physique up of unwanted heat can happen, which frequently leads to deformation of the work piece and surface snap. In certain instances, the forces introduced by the procedure are highly high and in order to procure the work piece considerable clamping forces are required ; this excessively can take to deformation. Together with these restrictions, the development of stuffs with belongingss of high strength, high hardness and high stamina has driven the debut of untraditional machining methods. Nontraditional machining ( NTM ) methods have been developed since World War II in an effort to turn to machining demands which can non be carried out by conventional methods entirely ( DeGarmo, Black & A ; Kohser, 2003 ) . NTM methods provide the ability to machine: Complex geometries ; Components with an first-class surface coating ; Delicate constituents, which otherwise would non defy the clamping forces ; and Brittle stuffs or stuffs with really high hardness. There are four types of untraditional procedures ; classified harmonizing to the principle signifier of energy used to consequence stuff remotion. These include: mechanical, electrical, thermic and chemical. One procedure which falls into the mechanical class is scratchy H2O jet ( AWJ ) film editing, and will be the focal point of this study. First, and prior to discoursing AWJ, the procedure of H2O jet ( WJ ) film editing will be introduced.Water Jet Cutting ( WJC )Water jet film editing, which is besides known as waterjet machining and hydrodynamic machining, was foremost developed in 1968, followed by the first commercial system in 1971 ( Zhong & A ; Han, 2003 ) . Through the usage of a all right, hard-hitting, high-speed watercourse of H2O directed at the work piece ( surface ) , a cut is created, as illustrated in figure 1 below. In order to bring forth the all right watercourse of H2O, a nose with an gap ( opening ) typically in the order of 0.1 – 0.4mm is used ( Groover , 1996 ) . Together with this, runing force per unit areas of around 400MPa and above are used to supply sufficient energy for cutting to be carried out. Furthermore, the fluid of the jet can frequently make 900m/s and the cardinal procedure parametric quantities include: H2O force per unit area, opening diameter, H2O flow rate and the working or ‘standoff ‘ distance between the nose and the work piece. Figure 1 – Schematic of WJC Process ( Groover, 1996 ) As the typical film editing force per unit areas as mentioned are required, a hydraulic pump is used to supercharge the fluid. The fluid is so passed through a valve, which regulates the flow rate in order to accomplish the optimal cut. The concluding phase of the fluid is to go through through the nozzle opening and impact the work piece surface from a controlled tallness.Procedure ParametersThe stuff from which the nose is made is doubtless the most of import parametric quantity in footings of procedure control ( as this greatly determines the opening diameter ) . The nozzle unit comprises of a unstained steel holder, together with a gem ; normally sapphire, ruby or diamond. Of these stuffs, diamond lasts the longest but is the most expensive. Recent progresss in the production of man-made sapphire offer this stuff as non merely the most cost effectual solution, but besides due to other advantages excessively. Man-made sapphire can be machined moderately accurately and besides has a high opposition to have on. The most common causes of nozzle failure are due to sedimentations come ining the fluid watercourse, therefore underscoring the demand for high degrees of filtration of the fluid prior to pressurisation, to cut down nozzle wear. With proper nozzle design a tight, coherent waterjet can be produced and maintained really accurately. When transporting out the cutting procedure, both the opening diameter and the ‘standoff ‘ distance must be closely monitored to keep a changeless deepness of cut. As the nozzle wears, compensatory alterations in the draw tallness must be made. Although existent draw distances vary from beginning to beginning, distances in the order of millimeters are normal ; normally around 0.25 – 3.5mm.WJC: Advantages and DisadvantagesWJC offers many advantages over conventional machining methods. This machining procedure provides the ability to cut stuffs without firing or oppressing the work piece. Furthermore, no important heat is generated, therefore, deformation is minimised and in some instances, eliminated. Unlike machining or grinding, no dust is produced ensuing in small environmental pollution. Other advantages include minimum material loss and easiness of mechanization when used with numerical control and industrial automatons. Whilst such advantages exist, one of the chief disadvantages to H2O jet film editing is that there are merely a limited figure of stuffs that can be cut economically ( MTU, 2009 ) . Although it is possible to cut tool steels utilizing this procedure, the provender rates have to be greatly reduced and therefore the edged clip increased. This, in kernel, consequences in a high cost procedure. Such stuffs that can be cut utilizing the H2O jet procedure include: plastics, fabrics, complexs, floor tiles, rug, leather and composition board.Abrasive Water Jet Cutting ( AWJC )To allow the film editing of difficult stuffs such as ceramics, metals and glass, together with those softer stuffs, for illustration froth and gum elastic, the WJC procedure requires the add-on of scratchy atoms, therefore organizing the scratchy H2O jet ( AWJ ) cutting technique. In a similar mode to WJC, the procedure is carried out utilizing a high-pressure, high-speed watercourse of H2O ; nevertheless, the discrepancy being that an scratchy stuff is dra wn in by a vacuity, which is created by jet watercourse. Figure 2 – Schematic of AWJC Process ( Meier, Louis & A ; Pilot, 1995 ) Figure 2 illustrates a typical apparatus for transporting out scratchy H2O jet film editing. It can be seen that this follows closely the agreement of WJC equipment, nevertheless, with the add-on of a twosome of cardinal characteristics ; viz. the scratchy eating system and a ‘catcher ‘ , which is required to protect the environment from the high energy jet.Procedure ParametersAs antecedently highlighted, the WJC procedure depends on a figure of parametric quantities. Whilst many of these are movable to the AWJC procedure, there are besides add-ons to reflect the alteration in cutting method. Momber & A ; Kovacevic ( 1998 ) present a list of such parametric quantities, which can be seen in figure 3 below. Figure 3 – AWJC procedure parametric quantities ( Momber & A ; Kovacevic, 1998 ) Although it is by and large accepted by many writers including JankoviA†¡ ( 2008 ) that the nose or opening diameter is the cardinal film editing parametric quantity, in the instance of AWJC, the abradant besides has considerable influences on the quality of the cut achieved. A choice of the parametric quantities as listed above has been explored in the subsequent subdivision, followed by an overview of the entire system control in the subdivision thenceforth.Procedure Parameters: Overview of Observed InfluencesThe most of import parametric quantity, by far, is the orifice diameter. The deepness of cut is straight relative to the opening diameter ; nevertheless, making an optimal point at big diameters. Although related to pump force per unit area, figure 4 below clearly illustrates this point, demoing how the deepness of cut varies with opening diameter. Figure 4 – Influence of opening diameter on the deepness of cut ( HeI?ling, 1988 ) Another parametric quantity that is closely linked to the opening diameter is the focal point diameter. This component of the cutting equipment determines the strength of the watercourse, therefore holding a direct consequence on the material remotion rate as shown by figure 5 below. Figure 5 – Influence of focal point diameter on the volume remotion rate ( Blickwedel, 1990 ) The focal point diameter is of import non merely in footings of the volume remotion rate but besides the deepness of cut. Figure 6 below shows how the deepness of cut is besides determined by this parametric quantity ; diminishing as the focal point diameter additions. The lessening in deepness of cut following an optimal point is realised by Himmelreich ( 1992 ) and has been attributed to high grades of turbulency. On the other manus, a peculiarly little focal point diameter gives rise to particle hit and clash, giving an inefficient procedure. Figure 6 – Influence of focal point diameter on the deepness of cut ( HeI?ling, 1988 ) Of the cutting parametric quantities listed, the crossbeam rate can be said to hold the greatest influence on the film editing procedure, followed closely by the draw distance. Both of these parametric quantities are controlled by machine design and therefore are bound by the makers ‘ specification. Figures 7 and 8 overleaf illustrate the influence of both the crossbeam rate and draw distance. It can be clearly seen that the deepness of cut lessenings as the crossbeam rate additions, following closely that of a squared map. However, on the other manus, the relationship between the draw distance and the deepness of cut is moderately additive ; with the deepness of cut decreasing as the draw distance additions. A big figure of scratchy stuffs are available for usage in AWJC. Typically these are loosely categorised as either oxides or silicates and there are, in a similar manner to the whole procedure, many parametric quantities that determine the features of an abradant. Figure 7 – Influence of crossbeam rate ( left ) and standoff distance ( right ) on the deepness of cut ( Blickwedel, 1990 ) Whilst it is hard to state precisely which parametric quantity has the greatest influence on the procedure, it is clear that both the hardness of the stuff together with the atom form and size, need consideration. Typical hardness values vary from 30 HV for Cd up to 200 HV for B carbide ( Kriegel & A ; Palmour, 1961 ) . Figure 8 shows the influence of both the atom form and size, whereas figure 9 overleaf high spots the significance of the mass flow rate of abradant on the deepness of cut achieved. Figure 8 – Influence of abradant ( atom ) diameter and size on the deepness of cut( Ohlsen, 1997 ; Oweinah, 1989 )Figure 9 – Influence of scratchy mass flow on the deepness of cut( Oweinah, 1989 )Abrasive Water Jet Cutting: Associated ProblemsIt is clear from the old subdivision that there are many parametric quantities that have an consequence on the AWJC procedure. If such parametric quantities are non carefully controlled, so the efficiency of the procedure decreases along with the quality of the machined portion. Some of the associated jobs are presented in table 1.Problem and definitionParameter ( s ) affected byConsequence on constituentTaper. This characteristic arises due to a difference in the breadth of the cut at the top surface and the bottom surface and is given as a ratio ( besides flank angle ) . Abrasive mass flow rate Focus diameter Standoff distance Trave rate This characteristic determines the dimensional truth of the portion. Initial Damage Zone. Abrasive atoms impact the surface at normal angles doing craters and abrasive-wear paths. Standoff distance Focus diameter ( Abrasive atom size – composite stuffs ) Some fictile distortion can happen. Change ( debasement ) in surface roughness/waviness. Trave rate Focus diameter/length Abrasive mass flow rate Abrasive atom size/type Surface belongingss of stuff are non as desired. Decrease in fatigue life of cut stuff due to check formation. Abrasive atom size Fatigue life reduced. Onset of stress-corrosion snap. Surface indurating due to procedure. Abrasive stuff Variation of hardness at distance from cut. Micro-structural alterations: Surface checking Phase alterations Abrasive-particle fragment implanting Delamination in composite stuffs Burr formation Assorted Assorted Table 1 – Problems that can originate when transporting out AWJCAbrasive Water Jet Cutting: Control MethodsTo guarantee such issues as those mentioned in table 1 do non happen, accurate control mechanisms must be in topographic point. There are many supervising mechanisms in topographic point today, some of which have been briefly described below. These methods lead to the control of the cutting procedure ; nevertheless, this is non automated in these instances. Jet-Structure Monitoring – used to command focal point diameter. Diameter of entry to concentrate point monitored to reflect alterations of focal point diameter. Wear rate can be monitored utilizing this method. Acoustic Sensing – used to supervise overall focal point conditions. System based on the fact that a alteration in the focal point conditions ( orifice diameter and concentrate diameter ) affects the sound generated by the system. Figure 10 ( overleaf ) illustrates the difference between the acoustic form of a new and worn nose. Inductive Measurement – used to supervise scratchy H2O jet speed. Method requires magnetic scratchy atoms. Abrasive jet is encircled by two little spirals, which is connected to a detection system. When the atom passes through the spiral, a little electric signal is created and the velocity determined. Figure 11 shows the typical apparatus of equipment, in this instance. Besides, laser systems similar to the above, nevertheless utilizing light pulsations alternatively. Material-Removal Visualisation – used to supervise material remotion rate. In a similar mode to Acoustic Sensing, noise of cut is monitored. Frequency of signal indicates type of cut ( inter-granular/trans-granular failure ) and therefore determines the efficiency of the cut. Workpiece Reaction Force – used to supervise deepness of incursion and surface topography. Empirical expression that takes into history all input parametric quantities excepting the crossbeam rate. Can go a force-feedback system ; leting parametric quantities to be modified to cut down the force. Figure 10 – Acoustic form for new and worn nose ( Kovacevic & A ; Evizi, 1990 ) Figure 11 – Initiation monitoring system ( Swanson, Kilman & A ; Cerwin, 1987 ) The above systems offer a chiefly generic attack to system patterning and supply small or no feedback. Modern control of AWJC makes usage of an intelligent monitoring and control system, which has full feedback capablenesss. Such an illustration by Srinivasu & A ; Babu ( 2008 ) utilises two systems: machine-vision based monitoring and intelligent control. The vision based portion monitors the size of the concentrating nose and the control system, which uses unreal nervous webs, continually modifies each parametric quantity to accomplish the best cut. A full analysis of this system is nevertheless beyond the range of this study. Abrasive Water Jet Cutting: Overview of Applications The applications of AWJC are huge, covering industries such as aerospace, automotive and electronics. It is beyond the range of this study to cover any peculiar country in important item ; nevertheless a few illustrations have been given below. Traditional and perchance even simple procedures have been ignored, and alternatively this study concentrates on a few non-standard applications.Meat CutingOne application of AWJ cutting is in the meat processing industry. Harmonizing to Wang & A ; Shanmugam ( 2008 ) , meat film editing is an of import activity and factors such as the cost, the presentation and sliting all need consideration. In this instance, salt is used as an scratchy and really good quality cuts, when compared to conventional film editing and even plain H2O jet film editing, can be achieved.Crunching Wheel ProductionThis illustration is slightly different to all other applications of AWJC as in most instances a through cut is desired. Axinte et Al. ( 2009 ) present an turn ing application, whereby crunching wheels are shaped harmonizing to their specification. Whilst this is considered a niche market, the writers conclude that AWJC has non merely the economical but besides proficient advantage for fabrication of this constituent. Assorted determining operations can be carried out, ensuing in such merchandises as figure 12 below. Figure 12 – Examples of crunching wheels manufactured utilizing AWJC ( Axinte et al. , 2009 )Polishing of SteelAnother application of AWJC is smoothing, and in peculiar steel. Yan et Al. ( 2008 ) describe this application, foregrounding that electrical-discharge machining ( EDM ) is normally used for mold production. The writers province that EDM typically leaves a brickle recast bed ; taking to the application of this smoothing method. When compared to traditional methods, AWJC has a lower scratchy ingestion and recycling is improved. In this illustration the abradant is SiC and to help the procedure is covered in wax. This consequences in a much finer surface coating.Complexs ProcessingThere are many applications of AWJC in relation to complexs treating as in some instances traditional single-point film editing procedures can non be used. For illustration, Komanduri ( 1997 ) describes that it is non possible to machine SiC whisker-reinforced aluminum oxide with a single-poin t film editing tool ; nevertheless, that it may be possible to determine by crunching. Whilst some complexs can be approached in this manner, rapid tool wear is experienced and therefore the debut of AWJC is a much better method.DecisionThe old subdivision provides a figure of non-standard illustrations where AWJC is being used. Although these give a general overview, AWJC can besides be used for alternate machining procedures, such as: milling, turning, piercing, boring ( although non level bottomed holes ) and thread film editing ( Momber & A ; Kovacevic, 1998 ) . Although such procedures as above can be achieved, in a similar instance to before there are many parametric quantities that need to be monitored. This is possibly a downside to this untraditional method unless modern control methods are introduced. Further disadvantages of the procedure include the fact that degradable stuffs can non be cut and the surface coating of machined constituents relies to a great extent on the procedure. Possibly the most important consideration of using this procedure is the apparatus cost ; which can be highly high in certain instances. One other disadvantage is the noise created by this fabrication procedure. Although, as highlighted above, there are many factors that control the procedure its application to modern industry has grown significantly since its debut in the 1970 ‘s. This has been driven chiefly by technological promotions, therefore leting this procedure to be developed, but besides due to of all time germinating stuffs that serve technology applications of today.
