Managing Business in Europe - Essay Example Though, there are lot of prominent automobile manufacturers in Europe, majority of the production of automobiles required for the European market is outsourced. The prominent automobile manufacturers in Europe are DaimlerChrysler, Volkswagen (VW), BMW, Ford Europe, General Motors (GM) Europe, Renault, PSA (Peugeot-Citro'n), Fiat and Porsche etc. "The EU is the largest automotive production region in the world and the industry comprises 6.5 % of the manufacturing sector in the Union. Direct employment by the automotive industry stands at about 2.2 million employees, while the total employment effect (direct and indirect) is estimated to be about 12 million" (THE AUTOMOTIVE SECTOR, 2009). This report analyses; Influence of EU's policies on Automotive Industry; Influence of Single European Market or EMU on Automotive Industry; Opportunities and threats for Automotive Industry associated with the enlargement of the European Union; Automotive Industry strategies for Europe etc. The increasingly international setting of business makes it harder and harder to establish the boundaries of a national economy or even to separate the European economy from its global context (Wallace &Young, 1997, p.3) Globalization and liberalization policies have revolutionized the who world and the business strategies were redefined in order to meet the demands of a global world by many of the organizations. Separate co-operative sectors are working in most of the parts of the world in order to exploit the possibilities opened by globalization. EU is one of such co-operation aimed at the integration of the whole European region for the collective growth. The current focus of the EU institutions is on making the EU one of the most competitive markets in the world by 2010 and ensuring stable economic growth. Efforts to this end include investment in human capital, improvements in physical infrastructure and enhancement of available network in the transportation, telecommunications and energy sectors. To counter sluggish economic conditions compounded by uncertainties due to geopolitical tensions and international terrorism, the European Commission has endorsed economic growth initiatives including European Action for Growth (Country Industry Forecast - European Union Automotive Industry, 2004) EU has implemented lot of strategies in order to encourage the automotive industries in the European region and to make the region, the world's highest automobile manufacturing region. At present the Asia-Pacific region holds this position and the EU has taken every possible measure to capture the first position. Environmental legislation and recycling legislation are some of the strategies adopted by EU in order to raise the standards of automobile manufacturing in this area. "The EU emissions standards are compulsory in all EU Member States. The

Criminological Theory - The Virginia Tech Massacre Essay
Criminological Theory - The Virginia Tech Massacre - Essay Example Popular Medias like television, film, video games and comic books have played a great role in increasing the violence among the young generation. Modern films are filled with scenes of violence; murders, rapes etc. Video games and other entertainment software include various aspects that encourage children and minors to engage in various types of violence. When children see their comic hero killing several people, they feel murder as a simple activity and dare to carry it out in schools and families. They resort to various forms of violence. Youngsters simply shot down their school and college mates for no reason. Violence is a hobby of the modern world. Pressure and stress can take adolescents to violence as they are not mentally strong to deal with the struggles in life. Public schooling is notorious for the pressure it puts on students. Students are forced to wear the ââ¬Ërightââ¬â¢ clothes, do the ââ¬Ëparticularââ¬â¢ assignment, and are pressured to be interested in v arious things which they are not naturally interested in. Individualism is ignored in this type of environment. Children are pressured to conform to certain rigid standards and rule. This rigidity is strong enough to disturb the psychological stability of children. They are increasingly affected by stress and anxiety that are caused by the pressures and work loads in their schools. This increased stress and anxiety creates undesirable behavior in children that lead to incidents like school shooting. Adolescents are highly vulnerable to anxiety and depression. In today's high-pressure corporate world, anxiety is a common feeling. People naturally become anxious. The emotional price of staying on top is always very high. Anxiety is unavoidable in such circumstances. As the person reaches the highest level of anxiety, a failure or an unexpected event can make him easily depressed. Anxiety disturbs the normal thoughts of an individual. The present world is the world of competitions. Edu cation and career filed have become highly competitive. ââ¬ËSurvival of the fittestââ¬â¢ is the theme of the modern academic field. Even little kids are out to achieve something in life. This generation is characterized by its excessive, exaggerated and disproportionate anxiety. A silly disappointment would finally push children into violence, depression, suicide and various other actions. Pressure and stress play a major role in incidents like school shooting. Adolescents are involved in majority of the school violence cases. Problems faced by the adolescents makes them resort of violence. They drink most, smoke most and have sex at very early age. They hate schools, neglect their health, and are least satisfied in their life. They donââ¬â¢t have any fellowship with their parents and hate their classmates. They lack good company and guidance. Adolescents are highly vulnerable to drug abuse and various other problems. Almost one third of the juveniles aged 12-to 20 use alco hol in US. According to the estimates nearly 11 million children or juveniles are alcohol consumers. According to the study conducted by the federal Substances Abuse and Mental Health Services Administration, nearly children and juveniles consume 20% of the alcoholic drinks in United States. More than 7000 children in United States start drinking alcohol everyday. All these culminate in events

Debate Between Abstract and Realism in Art
Debate Between Abstract and Realism in Art Consider the legacy of the Abstraction Realism debate for artistic practice in the 1950s in either France or Italy. Both culturally and politically post-war France found itself in a period of transition; as Findling, Scott-Haine and Thackeray (2000) state, the euphoria of 1944 soon gave way to agrim realisation of the socio-political consequences of the Vichy Governments collaboration with the Nazis and the challenges of reconstruction. The Fourth Republic, instigated in 1946 and continuing until the late 1950s, attempted to instil anotion of tabula rasa that would be mirrored in its art and culture. The abstraction-realism debate that had begun before the war and had, perhaps, found its ultimate expression in the Modernist oeuvre through such painters as Mondrian, Miro and others was, ironically, questioned at this time, for instance, in essays such as Jean-Michel Atlans Abstraction and Adventure in Contemporary Art (1950, 1997): Contemporary painting, being essential adventure and creation, is threatened by two forms ofconformity which we absolutely oppose: Banal realism, vulgar imitation of reality; Orthodox abstract art, new academicism which tries to substitute for living painting an interplay of solely decorative forms. (Atlan, 1950; published in Harrison and Wood, 1997: 612) Atlan here makes an interesting point and one that has an enormous bearing on the place of the abstraction-realism debate in 1950s France; for the post-war French artist the question became not how one should situation oneself in a polarity but is thatà polarity itself outdated and archaic. The tabula rasa of the socio-political sphere could be seen as a reflection of inter-war regression when translated to the aesthetic; the questionable politics of many of the Modernist writers, thinkers and artists making their work unattractive to thesons and daughters of the Fourth Republic. It was this psycho-social zeitgeist that, perhaps, ensured the twinning of art with prevailing theories of existentialism as John Macquarrie describes in his book of the same name(1972). For Macquarrie, post-war art (and particular those movements instigated in France) mirrors existentialism in its desire to negate the failures of pastontological systems and place the artist or philosopher at the centre of are constructive effort; an attempt to find meaning after the horrors of the war without recourse to external teleological notions like truth and beauty. This situation appears, to an extent, in Bretons Prolegomena to a Third Surrealist Manifesto: All present systems can reasonably be considered to be nothing on the carpenters workbench. This carpenter is you. (Breton, 1990: 287) In terms of the debate, then, between abstraction and realism both Atlan and Breton say essentially the same thing that what was needed culturally by post-war France was neither the consolation of realism nor the negation of abstraction but a synthesis of the two; an aesthetic that could both look forward into the future and signal a break with the past. We can see some of this in the work of Yves Klein. Both in terms of his painting and his photography, Klein constantly strove to achieve the kind of Hegelian synthesis we have been hither to looking at. Kleins work in the mid to late 1950s represented two paradoxical elements: on the one hand producing monochrome canvasses of a scintillatingly blue pigment (Monochrome blue sans titre, 1956; Monochromeblue sans titre, 1957) that all but obliterated any sense of the artist as producer of work and, on the other, laying the groundwork for the creation of action pictures whereby nude models would be used as brushes on huge canvasses (Monique, 1960; La Grand Anthropometrie bleue, 1960) that, literally, places the human being at the centre of artistic creation. In Klein we can clearly the manifestation of the legacy of the realism-abstraction debate in the France ofthe 1950s and, as we suggested, it lay in the synthesis of the two a similarnotion to the philosophical ideas of Sartre and Camus who sought an ontologicalmeaning without teleology. In fact it was some of this sense that culminated inthe creation of neo-realism, of which Klein was a leading figure and about whomPierre Restany wrote: We (the neo-realists) are thus bathed in direct expressivity up to our necks, at fortydegrees above the Dada zero, without aggressiveness, without a downrightpolemical intent, without any other justificatory itch than our realism. Andthat works positively. Man, if he shares in reintegrating himself in reality,identifies it with positively. (Restany, 1960, published in Harrison and Wood,1997: 711) What were neo-realists like Klein, Arman, Daniel Sporerri and Jean Tinguely but artists who attempted a fusion,and thereby a transcendence, of the archaic debate that Altman spoke of? We can see how such a view could beseen to lay the foundations for not only the postmodern movement in France that sought to find meaning in a post-Enlightenment world whose meta discourses in the words of Jean Francois Lyotard (2002: xxiii) were beginning to fail, but also the socio-political events of 1968 and the student uprising. Both of these can be seen to arise out of, or at least reflect, the aesthetic and cultural movements of the 1950s that sought to not only destroy the memories of the Vichy Government and the long years of Nazi occupation but also signal a progression away from the nihilism of Dada that left a void in the place of that which it negated. The legacy of the realism-abstraction debate, then, is one of Hegelian synthesis, arising out of the thesis and the antithesis. This situation was, perhaps, felt more strongly in countries suchas France, Italy and Spain where the political situation prompted a desperately needed change in aesthetic and ontological environment and where the need for a humanist consolation was as great as the need for an expression of the madness of the modern age.

This is a great time to be a graduate of Community College, because we are a group of students who are graduating with high grade point averages, leadership skills, overall talent, plus we are leaving behind much to be admired by future classes. Our class is also a very diverse and dedicated one. As if being a student alone was not a difficult task, many of our classmates hold jobs outside of school, are active in their communities as coaches, volunteers, athletes and leaders, and many have families to take care of. Our class has much to be excited about, many positive changes have come to our school because of the efforts of those in our class. We have held many amazing programs the past two years and especially this year. We have had several nationally known speakers and leaders visit our campus to inform us about local, national and international events. They have also come to our campus to see what has been going on here in Loyville and how they can use our models to aid other programs. We have had such speakers as civil rights activist Dick Gregory, Robert F. Kennedy Jr., local screen writer and producer Sherman Alexie, Gov. Gary Locke and U.S. Sen. Patty Murray. These past two years have also seen the addition in artwork here as well. Several new paintings and other hangings have been presented to the college, such as Dallas M. "Gray Eagle" Singhurst II's "Yu 'Pik fur seal mask" and the "Loyville Community College History Mural" painted by Bernie Webber. These artworks not only add to the campus but explain the history of the college and our community. There have been additions to school programs as well, including a women's soccer program, high school First Reach program designed to encourage local high school students to come to EvCC, a health and wellness series, and even a college rowing club designed to help students "catch the spirit of rowing." Members of the class of '99 and guests, I hold in my hand for you a special gift, from the classrooms of EvCC comes tonight's Top 10 List. These are the top 10 reasons to be proud to be part of the graduating class of 1999: 10.

Film: a Form of Literature and Understanding It
Film: A Form of Literature and Understanding It The purpose of literature not only describes reality but also adds to it. Itââ¬â¢s not merely a depiction of reality; it is rather a value-addition. Literary works are interpretations of the thinking patterns and social standards established in society. They are portrayals of the different aspects of everyday life. Literary works serve as a provision for thought and a boost for imagination and creativity. Reading and understanding literature can help someone understand life better. They help a person take a closer look at the different sides of life. In many ways, it can change one's perspective towards life. There are different forms of literature, like film. Film can be considered a form of literature. Literature is about telling a story and entertaining its readers. Film is the exact same way; it tells a story and entertains us throughout it. In film and literature they often relate to someone in some way. They can give lessons in life, and can have an influence on our behavior. This is because we often find ourselves trying to associate with what we see and search for similarities between these characters and ourselves. They can develop our progress to consider things morally. For example a movie with an anti-war theme can make a person rethink what war should be just because they portrayed the film in a particular way. This starts with reading what the film has to offer in terms of what itââ¬â¢s trying to portray. When trying to study what the film has to offer, itââ¬â¢s not just about what the movie is about and who is acting, but rather in what way the film is presented to you. There are five key elements to reading and analyzing film. These five key elements are the narrative, staging, cinematography, editing and sound. We will be analyzing the film Troy. In some films such as Troy there is narration in the beginning of the film as well as the ending of the film. It starts like this with Odysseus saying, ââ¬Å"Men are haunted by the vastness of eternity and so we ask ourselves: Will our actions echo across the centuries? Will strangers hear our names long after we are gone, and wonder who we were, how bravely we fought, how fiercely we loved. â⬠This foreshadows what the film is going to be about. It sets the mood for the film which you know is going to be about war and the legacy of the heroes who fought in the battle of Troy. The film ends with Odysseus narrating again. He says, ââ¬Å"If they ever tell my story let them say that I walked with giants. Men rise and fall like the winter wheat, but these names will never die. Let them say I lived in the time of Hector, tamer of horses. Let them say I lived in the time of Achilles. â⬠This just sums up how epic the film was in terms of showing the significance of the war and heroes. It makes you wonder about if Hector and Achilles were really that great. Staging consists of the setting, space, lighting, acting and choreography, and costume and make-up. The setting is very realistic in terms of the time period of which it supposedly happened. Itââ¬â¢s very symbolic to the film because it creates the imagery during that time. Every scene you see brings a sense of awe because itââ¬â¢s so realistic in terms of getting everything right with the costumes, the make-up and props used. The atmosphere and lighting of the film are very clear and natural. The acting was amazing and it definitely made the film more believable and the strong acting could manipulate sympathies towards the characters. It created suspense and complexity within the acting such as the battle scenes and emotional scenes. For example when Hector and Achilles face off, you donââ¬â¢t want either of them to die but someone has to. Hector has a wife and newborn baby while Achilles is out of vengeance and avenging his cousinââ¬â¢s death, creating complex emotions for the viewer. Cinematography was rather frustrating in Troy. In some scenes of the movie it looks much sharper than others. The other was the zooming; to me it was just too much and didnââ¬â¢t match some particular parts of the story. Like when Hector opens the doors of the city to face Achilles, it didnââ¬â¢t really make sense in this film. It just made it look way more dramatic than it needed to be. The editing done in the film had lots of cuts throughout the film especially the battle scenes, but they are necessary. The music of this film makes the story more dramatic to look at. The music is very on key with how they portray the scenes and characters in the movie. It creates a more epic effect with the music. The foundation of the important concepts to understand the movie Troy better are noticeable. From the sound to the staging and acting it makes the story more dramatic. It creates an artistic view to the film because of what itââ¬â¢s trying to portray based off the narration from Odysseus.

Resolving The Pure Enantiomers Of Phenylethylamine Environmental Sciences Essay
The intent of this research lab was to decide the pure enantiomorphs of ( à ± ) -?-phenylethylamine ( racemic ) mixture, by dividing their diasteriomeric derived functions utilizing ( + ) -tartaric acid. The differing enantiomorphs form different salts with acids. Two molecules that are enantiomorphs have about indistinguishable physical and chemical belongingss although this may be true, the salts that are formed after the reaction with acid have distinguishable belongingss. Some salts are less soluble [ ( + ) ( ââ¬â ) ] than others, and hence crystallize from the mixture in a about pure stereoisomeric signifier. When utilizing NaOH as a strong base to handle the salt, it allows for the isolation of the enantiomorph ( Lab Manual, 2007 ) . Polarimetry is a common method used to separate between enantiomorphs, based on their ability to revolve the plane of polarized visible radiation in opposite waies ( + and ââ¬â ) . This allows the perceiver to find the enantiomeric purenes s, and hence the composing of the mixture ( Wade, 2007 Chemical Chemical reaction: ( ââ¬â ) -amine ( + ) -amine less soluble salt [ ( ââ¬â ) ( + ) ] : crystallizes more soluble salt [ ( + ) ( + ) ] remains in solution 2NaOH+ 2H2O( ââ¬â ) -?-phenylethylamine ( Lab Manual, 2007 ) Procedure: Alternatively of utilizing a 50 milliliter beaker to boil the amine solution in, we used a 50 milliliter Erlenmyer flask For the remainder of the proceduce refer to pg. 18, 22-24 ( Lab Manual, 2007 ) Observations: The crystals were given a 4 hebdomad crystallisation period and afterward, the ( ââ¬â ) -?-phenylethylamine- ( + ) -hydrogen tartrate salt was observed to be a white crystalline solid, and the methyl alcohol was a crystalline liquid. Two really distinguishable beds were seeable following the reaction with the NaOH ( strong base ) and add-on of the methylene chloride ( CH2Cl2 ) . The top bed was translucent in some topographic points and opaque in others, really cloudy, white liquid, while the bottom bed was crystalline and besides liquid.

The ( ââ¬â ) -amine- ( + ) -hydrogen tartrate was much less soluble in methyl alcohol, and hence crystallized out of the solution ( Lab Manual, 2007 ) . This method of separation was proven to be rather successful, as the per centum output of this crystallisation was 73.1 % , which is comparatively high. The presence of drosss, every bit good as the inability to wholly crystallise the salt from methyl alcohol most probably attributed to any disagreements. It is besides possible that although the ( ââ¬â ) ( + ) salt is less soluble than the other salts, it still has some kind of solubility, and hence crystallizes instead easy ( hence the compulsory 2 hebdomad waiting period, in our instance it was 4 hebdomads ) . As good, the other salts, despite their high solubility in methyl alcohol, may hold still crystallized really somewhat over the long waiting period, adding to drosss Addition of NaOH resulted in the formation of two distinguishable beds: a white, cloudy aqueous bed ( top ) , and a clear aminoalkane bed ( underside ) , and allowed for the isolation of ( ââ¬â ) -?-phenylethylamine ( Lab Manual, 2007 ) . The add-on of 5 milliliter of H2O to the flask confirm that the top bed was the aqueous bed, since it increased comparative to the bottom bed and the H2O was absorbed here ( Lab Manual, 2007 ) . The aqueous bed consisted of the ( ââ¬â ) -amine, along with Na tartrate, and H2O, while the aminoalkane bed included any drosss. The Na tartrate readily dissolved in H2O, while methylene chloride ( CH2Cl2 ) was added to fade out ( ââ¬â ) -?-phenylethylamine ( boiling point ~ 186oC ) , since it had a lower boiling point ( 40oC ) , and could easy be removed through warming ( Synthesis and declaration of alpha-phenyethylamine. After a filtration procedure, including a series of extractions, there was per centum output of 61.3 % for the ( ââ¬â ) -?-phenylethylamine, which is a lower output than the original 73.1 % , bespeaking that there was a loss of aminoalkane during the 2nd portion of the experimental process. The chief cause of this mistake was the inadvertent disposal of much of the aminoalkane bed, in which a little sum of ( ââ¬â ) -?-phenylethylamine was still present. The presence of some drosss may hold besides affected consequences, nevertheless, they would hold alternatively increased the output and lead to deceptive consequences. Another possible cause of mistake is the little escape out of the glass stopper on the separatory funnel when the solution was shaken. There was a spot of solution that leaked out the underside or squirted out the top when let go ofing the force per unit area in the funnel. Subsequently, the mistake that well lowered the output of the merchandise greatly increa ses the optical pureness of the mixture. The ascertained rotary motion of the concluding sample was -31. 8o ( levorotatory, left manus rotary motion ) and the specific rotary motion was -33.8o compared with the empirical specific rotary motion of -40.4o à ± 0.2o ( Lab Manual, 2007 ) . The attendant optical pureness was 83.7 % , which is well high. Aside from the antecedently mentioned disposal of the organic bed, legion other mistakes, such as the presence of drosss may hold contributed to divergences in the optical pureness. The negative ( antagonistic clockwise ) rotary motion basically confirmed that the enantiomorph being isolated was the ( ââ¬â ) -?-phenylethylamine, and the high optical pureness demonstrated that the extraction was accomplished with much success and considerable truth, since the concluding merchandise was chiefly ( ââ¬â ) -amine, despite the comparatively low output.
