Racism against the African-American Essay

African-Americans since the beginning of slavery have suffered extreme segregation in all sectors of life. This group of people formed the civil rights movement in order to fight for their rights. This paper looks at the significant events which have changed the course of the civil rights movement in the United States. This paper will include the past and contemporary experiences of societal discrimination for this population, theories of identity formation, issues, and challenges as well as potential problems that result from discrimination and oppression. Various systems which directly or indirectly maintain the marginal position of the African-American in the United States society will also be looked at. Marginalization of African-Americans in United States society in social circles will also be looked at. Introduction Approximately one fourth of African-Americans, fall below the poverty line and continue to survive in poverty in America today (Riphagen, n. d. ). It is claimed that more than 50% of all African-American children in the United States today are living in poor conditions (Riphagen, n. d. ). One big question that arises from simply looking at the level of poverty among African-American families is how this discouraging picture of poor living conditions of a single ethnic community is possible in an industrialized, wealthy, as well as superpower nation as the United States (Riphagen, n. d. ). In modern U. S. society, one of the chief challenges remains to be the disproportionate social status of cultural minorities as compared to the Caucasian inhabitants. Even though, the United States is a wealthy and a prosperous nation, it is the white population that reaps and benefits from unequal share of privileges (Marable, 2007). African-Americans, who make a sizeable percentage of the country’s populace and being the oldest minority community, form the major oppressed group. African-Americans, according to Bandele (2008), are yet to benefit from social, economic and political equality as compared to the Caucasian community within the country. Even though other minority communities, for example Latinos, are also subjected to racial discrimination, African-Americans tend to experience a more severe yoke in regards to absolute numbers as well as proportions of families suffering from discrimination in any given community (Childs, 1993). The extent of poor living conditions among African-Americans is very high, and poverty for a lot of African-Americans presently, as asserted by Childs (1993), is still a harsh reality. It would be right to state that the American Dream has avoided a very big percentage of the African-American community. Nevertheless, as Marable (1997) indicates, neoconservatives have taken other races, for example Latinos and Asian-Americans, as model minorities attaining values that make a distinction between them and the African-American underclass (Childs, 1993). As Caucasians become more and more contented with their ability to attain the American Dream and believe in its transmission to African-Americans, the latter become extremely doubtful whether the dream can actually be attained for them (Marable, 2007). This is, in the first place, a result of a disproportional starting point and in addition established American values that play a vital function in hardships African-Americans go through. The prevailing American values go on portraying and presume that in spite of someone’s ethnic background, economic status, and place of residence, handwork is a major strategy that can enable a person to climb the social ladder and set up a better life (Riphagen, n. d. ). The strength of this assertion, however, has to be questioned as in numerous contexts appears to be used to lay the blame on African-Americans themselves for living in poverty, as it portrays a lack of motivation as well as being lazy (Hutchinson, 1997). Over the last few decades, African-Americans have gained considerable increasing opportunities in economic, political, as well as social circles (Bandele, 2008). From a circumstance in which absence of civil rights legislation resulted in extreme segregation of African-Americans from the dominant communities, presently the same civil rights apply to all people regardless of their ethnic background or gender (Riphagen, n. d. ). Though this may appear promising, it is not as positive and comprehensive as it might seem. The same civil rights, as Riphagen (n. d. ) argues, might be used and transcend races, though without stipulations, investments, in addition to inclusion to maintain this upward movement; it appears a rather impossible goal to attain. Nevertheless, even though numerous opportunities and inclusion portrays an optimistic move forwards, in regards to opportunities, it has fatefully had some negative effects too (Cohen, 2006). As an outcome of increasing visibility of on the global as well as national scene and have the wave of political turbulence that occurred in the 1960s, significant pessimistic attentions in addition to more negative perceptions of Americans of African origin have arisen (Marable, 2007). Whereas people became bitterer towards African-Americans, other people of color acquired the benefit of the doubt, as aggression to those communities was decreasing. Caucasian supremacy, though many deny of its existence in the 21st century, is one of the major factors that resulted in the oppression of the African-American community (Riphagen, n. d. ). A big percentage of Caucasian-Americans continue to directly or indirectly carry out various activities based on the doctrines of white supremacy. Studies, according to Riphagen (n. d. ), have revealed that the culture of African-American oppression have remained much the same over the years. Scholars claim that racism is still alive in the U. S. although its effects are less severe and portrayed in a more indirect manner as compared to the past (Cohen, 2006). When the issue of discrimination of African-Americans is looked at, one cannot help, but ask why African-Americans faced and continue facing marginalization in the social circle especially in the modern United States (Jackson, 2004). A continued marginalization of African Americans: Racism against the African American Slavery in the United States is one of the most significant events that clearly underlie a conceptual comprehension of racial discrimination (Childs, 1993). Slavery of Americans of African origin resulted in greater freedom for the unfortunate whites, even though it maintained a social framework that made sure that the latter remained poor. From time immemorial African-Americans have been used to offer undesirable services to benefit the whites (Riphagen, n. d. ). Slavery was part and parcel of the early American society to an extent that it was codified by the law. Hecht, Jackson and Ribeau (2003), assert that from the beginning of slavery to the present day, African-Americans have collectively been fighting for freedom. Racial difference is believed by many to have been a major cause of the American Civil War. Variation in ethnic backgrounds is also perceived to have been a major hindrance for reconciliation. However, the Civil War is claimed by many to be the demarcation point for beginning of African-American nationalism. Though it was the war that ended slavery, it was the biggest social tragedy that America has ever experienced. After the war, the lines of ethnic division became exceedingly apparent again (Riphagen, n. d. ). Civil rights movements, as indicated by Riphagen (n. d. ), aimed at reclaiming the social position of African-American community emerged in the 1960s. The civil rights movement however, did not make any remarkable contribution for redistribution of wealth along racial lines, or to encourage extensive ethnic restructuring addressing race and racial discrimination at the time. Even though legal equality was achieved, politicians argued that the endeavors of civil rights movements were immaterial (Bandele, 2008). They claimed that the most appropriate way to handle racism was integration. Many whites did not take into account the distinctive race consciousness of African-Americans. Wherever civil rights activists emerged, this resulted in great anxiety amongst whites. Integration is therefore believed to have directly and indirectly resulted in neglect as well as lack of dedication to the vitality of African-American population (Childs, 1993). Research, as asserted by Riphagen (n. d. ), reveals that the skepticism of Caucasian-Americans to the notion that racial discrimination is the factor that hinders upwards mobility of African-Americans. A majority of the whites are comfortable with the way African-Americans in society are treated. On the other hand, however, African-Americans are embittered by the way the society, and in particular the white population treats them (Hecht, Jackson and Ribeau, 2003). It is unfortunate that bias towards African-Americans is only rising along with a stagnating image of progress of African-Americans community in regards to education, housing and job availability. Studies reveal that most whites in America believe that African-Americans are lazy and violent (Jackson, 2004). Research has also revealed that a majority of white-Americans believe that African-Americans live in poverty as a result of their lifestyle (Riphagen, n. d. ). This unending stigmatization of a whole race, grounded on group characteristics, highly discourages African-Americans from developing their talents and makes it very hard for them to succeed in the eyes of mainstream white-Americans. Bias, as Hecht, Jackson and Ribeau (2003) argues, also continues in situations whereby observations gathered from broadly concentrating on the African-American underclass who are not employed are taken as a representative of the broad sweep of African-American across American society. Nevertheless, inherent in focusing on the unemployed African-American underclass is possibly trying to avoid acknowledging unfair as well as racist practices and policies (Marable, 1997). The prison department in the United States, as illustrated by Free (2003), locks up more people as compared to other industrialized countries in the world. Another fact in regards to the U. S prisons is that the proportion of African-American in them is disproportionate as compared to other races. African-Americans make up the largest percentage of the prison population in the United States (Riphagen, n. d. ). This enormously grim image has been scrutinized by intellectuals to determine whether the criminal justice system is made up of a legitimized regulatory system over minority communities, or whether it is a fact that African –Americans commit more offenses (Free, 2003). All in all, there is a major difference in regards to the magnitude of the offenses committed by African-Americans and the extensive burden of the jail sentences by which they are penalized. Intellectuals perceive policies set in such a way as to put more African-Americans, particularly males, in jail as a clear scenario to regulate as well as restrict African-Americans communities in regards to activities and progress (Free, 2003). Selective rules, particularly targeted at offenses committed in grater ratio among African-Americans, have led to inconsiderate along with longer sentences for African-Americans. Free (2003) makes it clear that little, if any, strategies are put in place for treatment and prevention of crime making it quite clear that the exact agenda is to control the problem, instead of tackling the cause of the problem. The high rate of crime drives investors away from the African-American neighborhoods, in turn leading to adverse implications on the economic and social conditions of all African-Americans (Riphagen, n. d. ). Prisoners, majority of who are African-Americans males, in different states are banned from voting (Free, 2003). Research reveals that a very large percentage of African-American men are in prison as compared to those enrolled in formal education (Riphagen, n. d. ). Along with educational segregation, housing segregation is one of the most traumatizing systems in the United States today. African-Americans over the past fifty years have experienced the worst form of housing segregation as compared to other American communities. Housing segregation not only affects African-Americans of low socio-economic status, but also those of higher socio-economic strata (Marable, 2007). Housing segregation not only underpins unfairness, but also increases it. Various properties belonging to the African-Americans, due to the extremely segregated nature of separated locality, continues to suffer from devaluation in terms of its minimized desirability leading to a drop in value as compared to properties of equal nature found in predominantly white neighborhoods (Childs, 1993). This scenario makes white communities to move out of localities inhabited by majority African-Americans. Housing segregation is also displayed whereby estate agents only show African-Americans only a small proportion of existing housing, while steering white-Americans away from neighborhoods containing a large percentage of people of color (Free, 2003).

Dialectical Behavioral Therapy

IntroductionDialectical Behavioral Therapy is a cognitive behavioral model of psychotherapy used primarily to treat individuals diagnosed with Borderline Personality Disorder (BPD). The treatment was manualized in 1993 (Linehan, 1993a; Linehan, 1993b) and met criteria as an empirically validated, well-established treatment for BPD in 2001 (Koons et al, 2001). DBT has also been found to be effective in a range of treatment settings with a variety of populations.The empirically based treatment of DBT is a series of cognitive behavioral strategies that are applied to BPD populations. The approach provides psycho-social skills training to encourage development of effective cognitive, emotional, and behavioral skills. Learning DBT skills increases a client's ability to achieve positive outcomes by systematically developing effective coping mechanisms, and facilitating the decrease of maladaptive behaviors (Linehan, 1993a; Linehan, 1993b).The characteristics that distinguish DBT are: (1) t he immediate focus on acceptance and validation; (2) the emphasis on treating behavior that interferes with therapy; (3) the emphasis on the therapeutic relationship; (4) the focus on dialectics, synthesis, and process (Linehan, 1993a).DBT Theoretical FrameworkDBT is based upon a dialectal view of human behavior consisting of three primary principles. The first principle is one of interrelatedness and wholeness: a system must be analyzed as a totality, as the parts are temporary and only exist in relation to the whole. The second principle is polarity: reality is not static but is made up of opposing forces, that when integrated, create a new set of opposing forces.The third principle is continuous change: the tension between oppositional yet connected parts produces a process of change, rather than a structure, which is an underlying condition of human nature (Linehan, 1993a).In the DBT process, change occurs in the midst of dialectical tension. This tension is a process created by the client's attempt to maintain homeostasis, while the therapist uses persuasion techniques to support the client's process of self-transformation. The therapist overcomes the client's resistance by on-going dialogue with the client that is both encouraging and directive (Linehan, 1993a).One of the core components of DBT is increasing the capacity to regulate emotions (Linehan, 1993a). Among persons suffering from Borderline Personality Disorder, the inability to regulate emotions results in emotional vulnerability and maladaptive strategies for coping. Emotional vulnerability is defined by (1) high sensitivity to emotional stimuli, (2) intense response to emotional sensitivity, and (3) difficulty reducing the sensitivity and returning to a normal emotional baseline.Similar to Cognitive Behavior Therapy (CBT), DBT also includes ongoing self-monitoring of behaviors, realistic treatment goals, a strong therapeutic alliance, and treatment compliance. Client agreement in the manualize d treatment includes, but is not limited to the following: (1) A commitment to a one year, renewable agreement, (2) Compliance to the weekly meetings and attendance, (3) Notification to the therapist in advance if they are unable to attend scheduled therapy sessions, (4) Confidentiality in group settings, (5) Willingness to work on any and all problems that interfere with therapy, (6) Agreement in group treatment settings to not form personal or sexual relationships with other group members, (8) Commitment to not come to therapy under the influence of drugs or alcohol, and (9) Willingness to participate in both individual and group treatment if appropriate (Linehan, 1993a; Linehan, 1993b).Therapist agreements in the manualized treatment include but are not limited to: (1) Professional and reasonable effort to conduct therapy with client, (2) Adherence to ethical guidelines, (3) Attendance at all scheduled sessions, and if unable, agreement to reschedule with advance notice, (4) Agre ement to respect the autonomy and integrity of the client, and (5) Confidentiality within the confines of the law (Linehan, 1993a).DBT PhilosophyIn order to truly examine DBT, it is first important to examine how Marsha Linehan designed DBT to treat BPD. In her book Cognitive-Behavioral Treatment of Borderline Personality Disorder, Linehan (1993 a) described DBT as the application of cognitive and behavioral therapy strategies to help work through problems.DBT is based on a dialectical philosophy that emphasizes reality as an interrelated system composed of opposing forces that are continuously changing. At the core of this philosophy is accepting the client as they are while assisting to promote healthy change. Linehan (1993a) further described DBT as:The emphasis on assessment; data collection on current behaviors; precise operational definition of treatment targets' a collaborative working relationship between therapist and patient, including attention to orienting the patient to the therapy program and mutual commitment to treatment goals; application of standard cognitive and behavior therapy techniques, (p. 19)DBT therapists use treatment procedures such as problem solving, exposure techniques, skill training, contingency management, and cognitive modification to help clients find new ways of working through the problems that brought them into therapy. DBT â€Å"requires that the therapist balance change and acceptance in each interaction with the patient† (Linehan, 1993a, p. 19).This treatment philosophy along with the application of problem-solving and validation strategies becomes the DBT process (Linehan, 1993a). DBT â€Å"blends a matter of fact, somewhat irreverent, and at times outrageous attitude about current and previous parasuicidal and other dysfunctional behaviors with therapist warmth, flexibility, responsiveness to the client, and strategic self-disclosure† (Linehan, 1993a, p. 19).DBT works to reframe suicidal and other dysfu nctional behaviors that had previously been part of the clients learned problem solving patterns. Therapy focuses on active problem solving and is balanced with a corresponding emphasis on validating the client's current emotional, cognitive, and behavioral responses as they are in that moment. Focus on dialectics and the balance of acceptance and change are crucial elements of the DBT process (Linehan, 1993b).DialecticsAlthough DBT has similarities to standard cognitive and behavioral techniques, it also has many defining characteristics that make it a unique treatment. It is important to review the key elements of DBT in order to extend its application to a population such as BPD. For example, DBT emphasizes dialectics. Dialectics can be described as the â€Å"reconciliation of opposites in a continual process of synthesis† (Linehan, 1993a, p. 19). It stresses â€Å"interrelatedness and wholeness, parts of a system is of limited value unless the analysis clearly relates th e part to the whole† (Linehan, 1993a, p. 19).DBT therapists work with clients to examine a more global meaning to what had previously been polarized as extreme ideas or thoughts. Linehan stated that the most fundamental dialectic is the necessity of accepting patients as they are within a context of trying to teach them to change. Linehan continued by stating that â€Å"reality is not static, but is comprised of internal opposing forces, thesis and antithesis, out of whose integration (synthesis) evolves a new set of opposing forces† (Linehan, 1993a, p. 19).Linehan described how although dialectics focus on the whole, they also emphasize how complex the whole can be, including the oppositions they contain. With this notion in mind, DBT places an emphasis on acceptance as a balance to change (Linehan, 1993a). DBT therefore focuses on accepting the client for who he or she is in the moment, while also working toward more effective behaviors and ways of interacting with on e's present experience and the environment.In addition, DBT emphasizes the necessity of teaching clients to accept themselves and their world as they are in the moment. Linehan discussed how this unique strategy works well with BPD because it provides the validating environment so crucial to those with injured self-esteems. She also discussed the importance of providing a structured setting to learn and practice new skills.DBT includes both acceptance of the patient's experiences including validation of their emotional pain and suffering, and offering new psychological coping strategies that include a refocus on meaning and substance in their life, exposure to previously ‘intolerated' emotions, prevention of emotional escape, and introduction of a behavior focus. (Marra, 2005, p. 7) This behavior focus includes â€Å"goal orientation and new solution-based strategies to replace maladaptive coping skills† (Marra, 2005, p. 7).An important caveat to remember as treatment p rogresses is that there is a natural process of change that occurs as treatment progresses. Linehan discussed how DBT assumes that reality is a process full of movement and change. Therefore, immediate client stability and consistency are not a focus. Conversely, acceptance and movement with change are key elements of this process. The therapist and client work together in a changing relationship and a changing environment (Linehan, 1993 a).In her work with individuals who struggled with self-injurious and suicidality, Linehan utilized dialectics and the philosophy of balancing acceptance with change to enhance treatment effectiveness. She also observed that most of her clients presented with BPD characteristics. As such, she incorporated dialectical philosophy as the bedrock of her treatment when designing DBT for individuals with BPD characteristics.

Chaucers Justinus and Placebo

Why do you think Chaucer includes Justinus and a placebo? What is the contribution of the latter discussion to the entire story? There are many factors gathered by the readers to keep the readers away from the characters in the story, especially from the complex and ambiguous series of shots they are seeing. They are all smaller or larger types or allegories. Justinus and Placebo are anthropomorphic allegories representing abstract attributes of good proposals and bad suggestions. It is derived from satirical and contemporary recommendations of the courts. There, there is told the recipient, usually the Prince, how to choose good counselors and avoid compelling their motivation as their own progress. In January, Discussion (1474) between two friends, placebo and Justinas announced that he decided to marry his soul (1400-1405). Now, this so-called controversy has brought about a sarcastic existence that existed since marriage debate, but businessmen - and some commentators - did not f ully know this, and he was one of his goals It is one. Basically speaking, there is no discussion about debate about marriage, and hoolynesse or dotage which is a substitute for merchants in this case includes a distinction without distinction. When placebo praised the decision of January (1478 - 1518), Justinus warned him that he should not hurry to do a tough and dangerous deal (1521 - 65), and they correctly won January The concept of marriage was defined. A sanctified way for men to meet (status). Betting is more like steak than old beef (1420) Like Justinus, as I pointed out already, I cite Bath's wife ironically, but Justinus is not worthy to argue against (1655ff.), But readers like Justinus may think unknown. Institution (1685) - 87) In fact, however, the issue of two blessings in January is a true theological problem in the 14th century. Dante discussed this in the fourth article of De Monarchia and Convivio The most authoritative index of the 13th century is the tradition of Albert the Great and Thomas Aquinas and of course also included in his two paradises. Medium, the land of Plugatrio and the land next to it. Indeed, from a traditional theologian's point of view, January stated the problem in the wrong way as he began with an irrational premise - Justin tried to destroy him - the marriage is a perfect Earth We guaranteed happiness The manuscript of Diodorus ceased at the end of the 4th century BC and the surviving sources became very fragmented. For a continuous story, we have to go to the epic of Pompeius Trogus by the later Latin writers Justinus, but his explanation is relatively short, contemporary readers tell us the sequence of events he describes It may confuse. In the absence of a satisfactory continuous record Plutarch 's parallel life provides important insights into some of the most influential figures of the era: Dmitryus, Pirhus, Alatus, Ajis and Clemens. Plutarch has often been pointed out as a biographer, not a historian - but when he wrote his life he examined various modern history.

Is Turkish law incompatible with EU membership Essay

Is Turkish law incompatible with EU membership - Essay Example Ten years ago Turkey applied for accession to the European Union.Till today the accession has not be granted.Mainly because of the huge overall concern that Turkey is not what is perceived to be a truly democratic and free countryOne largely ignores the fact that not half a century ago that what was mostly a divided and warring section of Mediterranean countries like Greece, Spain and Portugal is now today an integrated and peaceful Europe and the European integration project in which Turkey wants to join, has brought Europe together into a cohesive whole creating a 'security community' within an ever growing community where there is a "democratic peace". Former authoritarian and militarily dominated countries have come together. And the conditionality for the membership 'peace and cooperation' has been the most potent tool for the drawing together of diverse cultures and groups such as French, German, Poles, Hungarian and Romanian countries. Dialogue and a mutual sense of security e xists where earlier there was only confrontation and suspicion. Till today Turkey's dream of integration into the EU is still a dream. A virulent debate still rages over whether Turkey will strengthen EU's 'democratic zone' or destroy it and undermine the functioning of the EU through its action, most of which is considered as unlawful in the EU.The most prominent argument is that Turkey is a hardliner and the regions surrounding Turkey is filled with instability, violence, terrorism and political instability with hard-line Islamic fundamentalism. But internationally prominent figures like George Bush and Condoleeza Rice, Tony Blair are all for the process of Turkey's integration into the European Union. Olli Rehn (assumed office as EU Commissioner for Enlargement on 22 November 2004,) is the President of the European Commission responsible for Enlargement of the European Union (ENP), which was adopted in 2003. EU borders are being stretched now to the Middle East and World borders are breaking down. Increasingly Turkey is starting to play a prominent role. It is shedding the coercive aspects of its political views and laws are becoming much more liberal and dependent on dialogue and cooperation, dismantling prejudices and promoting mutual trust. The Portuguese Foreign Affairs minister recognized this and after the Brussels Council meeting in 2005 he said 'the US will be pleased and Bin Laden will be disappointed'. This was the meeting where it was decided that talks on Turkey accession to the EU would start. With this accession to the EU it's credibility and influence in world politics and the Muslim world will increase significantly. Prominently opposition was because the Turks did not allow freedom of expression. For a long time challenging status quo in Cyprus amounted to treason and the Anan Plan was criticized and applauded in turn. The Prime Minister, Tayyip Erdoan (wanted a "win-win" solution) Discourse of this kind was a new phenomena and a novel one in Turkey and undoubted this was the pressure that was created due to the EU and the prospect of accession. On 12th September 2005 was published the 12 cartoons by the Danish newspaper Jyllands-Posten which showed the Muslim Prophet Muhammad in a variety of humorous or satirical situations. Turkey and the Muslim world clashed with the western world. Danish Prime Minister Anders Fogh Rasmussen's nomination as NATO's new secretary-general due to his stand in 2005 in this issue lead to his leadership being strongly opposed and the rights and the freedom of expression in the Muslim world being strongly questioned. It seemed to be incompatible with the U.N declaration of human rights. Muslims complained about an 'ongoing smear campaign' in Denmark against Islam and warned that negative reaction could result in Muslim countries and Muslim communities in Europe. They called on the prime minister "to take all those responsible to task under law

Association of corticosteroid dose and route of administration with Article

Association of corticosteroid dose and route of administration with risk of treatment failure in acute exacerbation of chronic obstructive pulmonary disease - Article Example bation of chronic obstructive pulmonary disease or emphysema or failure of the respiratory system along with either COPD or emphysema. Two groups were formulated which included patients who were treated on low doses of corticosteroids which were administered orally as well as patients who were treated with high doses of corticosteroids which was given intravenously. After the high dose intravenous route, the number of deaths were 1.4% (95% confidence interval [CI], 1.3%-1.5%) and the patients who responded with primary outcomes were 10.9% (95% CI, 10.7%-11.1%) According to the multivariable regression model, the risk of the patient not responding to treatment via the oral route was less than that via the intravenous route that is (odds ratio [OR], 0.93; 95% CI, 0.84-1.02). This model was to analyze the effect of the route chosen for the corticosteroids with the primary and secondary outcomes of the patient. High dose intravenous therapy does not provide any major benefits which are superior to the results of treatment with low dose corticosteroids administered orally. Rather the intravenous therapy is associated with pain and carries a risk of infection and higher costs in comparison to the oral low dose corticosteroid therapy. The research does provide strong support about the authors conclusion that low dose orally administered corticosteroids hold the same if not superior results for patients with acute exacerbation of COPD. This research should be sufficient to reduce the health care costs imposed by COPD because it is one of the leading problems in the United States. Low doses of corticosteroids orally would result in lower adverse effects along with reduced cost and hospital stay. Hence the results of this research should be effectively utilized. About 92 percent of the patients were given intravenous therapy whereas

Middle Ages Magic Activities from Religious Point of View Assignment

Middle Ages Magic Activities from Religious Point of View - Assignment Example The Church did not approve of theories that contradicted the official doctrine of the Church. This is because their view of human knowledge is based on a concept of an all-knowing God and a revelation of absolute truth through the scriptures and through the Pope and the senior leaders of the Church. There was no room for theories that were based on principles outside this rather strict set of rules. The whole issue of whether the earth is the center of the universe, for example, was seen as a theological dogma, not a theory or scientific view, and these issues have the potential to cause the whole foundation of Christian belief to crumble if they are challenged and found to be false. That is why the Church resisted any other views. There seems to have been in Medieval times quite a bit of experimentation with these forbidden arts, just as today people read horoscopes, go to see fortune tellers, and have lucky objects at the same time as holding broadly orthodox beliefs in one of the main religions. Old pagan beliefs linger on in symbolic ways, as for example in the Christmas trees, Harvest Thanksgiving services and Easter eggs that we have in Western culture, even though these are symbolic of pagan festivals (Jolly, 2000, p. 1). In this, there is not so much difference between medieval and modern society. The issue of predetermined events and the prediction of human behavior was a very thorny one because it goes to the heart of the Christian doctrine of salvation. It matters a lot, for example, whether a person has free will or not, and whether they freely choose to do good or evil deeds, or whether they are just puppets being manipulated by fate or some demon or other. Christians have a strong sense of being morally responsible for their actions, and relying on God alone, and so many other forces that get in between a man or woman and their god were seen as a bit threat.  

Tata Steel in India Research Paper Example | Topics and Well Written Essays - 1750 words

Tata Steel in India - Research Paper Example Tata Steel is recognized as India’s first Iron and Steel company, having been founded in the year 1907 during the British colonial era. (Indicus Analytics, 2009) Tata Steel operates as part of the Tata Group, allowing it to pursue integrated supply and distribution facilities to automotive manufacturing, heavy industry, and consumer goods production within the conglomerate’s structure. (Economy Watch, 2010) Tata Steel competes with a large number of different Iron and Steel companies within India’s domestic economy and internationally, including the Steel Authority of India (SAIL), Arcelor-Mittal, POSCO, Hindustan Steel, JSW Steel, and other companies. The Indian Government has pursued a policy of progressively opening India’s local economy to foreign competition, and there is currently no levy or tax restriction on the import and export of iron and steel products. (India Ministry of Steel, 2009) The consequence of this is considered to be increased compet ition in the sector, and lower prices, particularly as set by Chinese steel producers for export. China produced over 10 times the steel capacity of India, at 567 million metric tons in 2009 compared to 56.1 million metric tons produced by India in the same period. (India Ministry of Steel, 2010) Nevertheless, Tata Steel has produced a corporate strategy to meet these competitive challenges, and this includes sustainability policies directed at the greater welfare of workers, the environment, and community. Tata Steel and Economic Conditions in India Tata Steel states publicly that â€Å"the primary purpose of a business is to improve the quality of life of people.† (Tata Steel, 2011) This tenet constitutes the cornerstone of the company’s sustainability policy and represents the wider mandate held by corporate management on behalf of stakeholders. In India, there is a need for social and economic development that uplifts people out of poverty. One of the main processe s that enable individuals to improve their living condition in the modern, globalized economy is the possession of a professional, well-paying job. Another factor is the level of education that an individual receives in the formative years of development. Education is recognized as vital to the long-term sustainability of business and industry, as well as being one of the main constituents of what is required of a good employee. As India’s economic development needs change on a national level from addressing the dire threats of the poverty situation of the post-colonial era through socialist policies to supporting the booming economy expanding at a rate of 8% to 10% annually in the 21st century through progressive market policies, it should be expected that the sustainability policies at Tata Steel are also updated and analyzed by management teams to reflect the changing requirements of the communities themselves that are being served.

Strategic Management, Organisational Strategic Analysis on Barclays Essay

Strategic Management, Organisational Strategic Analysis on Barclays PLC - Essay Example Introduction Barclays PLC is a major global financial service provider that is engaged in retail banking, credit cards, corporate and investment banking, and wealth management with an extensive international presence – Europe, Africa, Asia and the Americas (Barclays, 2011). The company has its roots in the UK, which has remained as its major market in terms of income, personnel – about 60,000 – and other resources. As a big financial services provider the company is structured as follows. First it is divided into the three major categories: (1) retail and business banking; (2) corporate and investment banking, and wealth management; and (3) group centre. The retail and business banking is further subdivided into four business segments: UK Retail and Business banking, Europe Retail and Business banking, Africa Retail and Business Banking and Barclaycard. Corporate and investment banking is subdivided into: Barclays Capital, Barclays Corporate and Barclays Wealth. Global centre comprises of all the other operations at the company’s head office (Barclays, 2012a). In 2010, the group had made a total income of  £31,440 million and had nearly 147,500 employees globally. This research paper shall focus on the company’s UK Business Banking segment.... The retail and business banking is further subdivided into four business segments: UK Retail and Business banking, Europe Retail and Business banking, Africa Retail and Business Banking and Barclaycard. Corporate and investment banking is subdivided into: Barclays Capital, Barclays Corporate and Barclays Wealth. Global centre comprises of all the other operations at the company’s head office (Barclays, 2012a). In 2010, the group had made a total income of ?31,440 million and had nearly 147,500 employees globally. This research paper shall focus on the company’s UK Business Banking segment. According to Antony Jenkins, the Chef Executive of Global Retail Banking, the company’s strategic goals are â€Å"Happy customers, strong profit growth, good returns (Barclays, 2011, p.18)†. However, this may prove to be quite a challenge considering the effects of financial crisis of 2008 and the current recession in most of Western Europe (the UK included) which ar e major markets for the company. One key change that the bank will have to contend with is increased stakeholder involvement and expectations as depicted in Appendix A. 2.0. Analysis of the Internal and External environment PESTEL analysis enables a company to analyse its macro-environment. From the macro-environment the company’s strategist can then figure out which factors are more likely to change and which amongst these will have the greatest impact on their organisation (Gillespie, 2007). Five forces analysis helps a company to understand the structure of its industry and stake out a position that is less vulnerable to attack and more profitable (Porter,

Pro Porn Feminist view of career in Pornography Essay

Pro Porn Feminist view of career in Pornography - Essay Example Pornography has provided female pornography actor with the financial augment they need, especially after becoming a widow or due to the lack of suitable jobs for qualified female pornography actor. Now pornography has turned into one of the biggest and most profitable industry and thus has invited a lot of interest and charm for female pornography actor to turn towards pornography in order to make some quick buck. Before we discuss the various views of female pornography actor working in the porn industry, we should define the definition of pornography. Although this has been a very debated topic too, as various authors find the definition in quite contrasting views. However, a generally accepted definition for "Pornography" is: "Pornography (from Greek pornographia - literally writing about or drawings of harlots) is the representation of the human body or human sexual behaviour with the goal of sexual arousal, similar to, but (according to some) distinct from, erotica."(Wikipedia) It has been arugued that pornography is "degrading" for female pornography actor. However, I believe that degrading is a very vague term. It narrows down to the point where every individual is in the position to define what is "degrading" and what is not. Another thing linked to this debate is that female pornography actor are used as "sex objects" and thus their importance mitigated. If this objection is taken at face value, it is meaningless, as objects do not have sexuality, only beings do. But if we state that female pornography actor are depicted as "sexual beings" would make a poor idiom. Most female sex workers foster the view that pornography should not be restricted, not because they oppose restricting harmful speech, but because they regard pornography as relatively harmless. They identify the harm of pornography as the harm of offense and maintain that the fact that some find certain materials offensive is not a sufficient reason for restricting those materials.( Gittler,2000) However, despite the benefits of porn, there still remains strong advocates of anti-porn. MacKinnon has disagreed that pornography is an action, instead of a form of expression. In her work titled "Only Words" she strongly presents the view that pornography is an illocutionary act of subordination. Another way that MacKinnon tries to augment the view that pornography is an action involves a similarly glaring non sequitur: "Pornography is masturbation material. It is used as sex. It therefore is sex."(Mackinnon 2000) The fact that pornography is used in certain actions, though, does not make it the case that pornography is an action. Finally, MacKinnon asserts that pornography is an action because it causes harmful acts. MacKinnon defends that pornography is causally linked to acts of sexism and violence against female pornography actor. Another important argument raised against female pornographic actors is that pornography entices men to commit rape. Studies and experts have contracted this view and have refused to accept any links between the two things, which they consider as poles apart. To further proof this point, the highly "pro-censorship" Messe Commission Report also agreed to this fact.( Jones,2001) Take the case of Japan, where pornography and

Spy Virus Linked to Israel Targeted Hotels Article

Spy Virus Linked to Israel Targeted Hotels - Article Example Moreover, Israeli has previously targeted events attended by prominent world leaders, and the fact that the virus was also in computers utilized in the commemoration of the 70th anniversary of the Nazi death camp confirmed the suspicion that Israeli was behind the cyber attack. Even so, the degree of sophistication of the virus has made it difficult for security experts to determine what kind of information the hackers stole. In fact, security experts estimate that it could take ten adept computer scientists â€Å"more than two years to build such a clean copycat† (Entous and Yadron, 2015). Overall, Kaspersky is relentlessly attempting to study the manner in which this sophisticated virus works before embarking on a mission to establish powerful antivirus programs to protect customers from cyber security vulnerability. Cyber criminality has been around for a long time. However, what is striking is that hackers are taking their ‘game’ to a completely new level. Hac kers have come to learn that by targeting security companies, they can learn quite a great deal about internet defenses. For instance, Kaspersky was a victim to the attack since the Israeli had a hint that Kaspersky antivirus programs protected the networks and computers in the target hotels. Following a successful attack on Kaspersky, it would be easy for the hackers to spy on their desired information. Verdonck (2015) affirms that hackers target the most vulnerable links in the company, who are the people. Kaspersky was no exception.

Rogers Chocolates Essay Example for Free

Rogers Chocolates Essay 1. The premium chocolate industry is changing dramatically with the growth rate in the chocolate industry falling as a whole, other traditional big name chocolate companies like Hershey’s and Cadburys are moving more towards the premium chocolate industry. The premium chocolate industry growing 20 percent annually and with the baby boomers purchasing more chocolate, they put are putting great emphasize on quality and brand when they purchase their chocolates. The underlying drivers of change are changes that companies go through in the industry and competition conditions. There are 14 total driving forces that drive industry change but Roger’s chocolates has 6 driving forces in particular that affect them the most. First are the changes in the long-term industry growth rate because of the decreasing growth rate in the chocolate industry. Second are the changes in who buys the product and how they are used because as mentioned in the text, 20 percent of the â€Å"heavy users’ account for 54 percent of the pre-Christmas sales. Third is marketing innovation because their customers and clients had environmental concerns in bettering their packaging, procurement, and operational decisions. Fourth driving force are the entry or exit of major firms and this can been seen with companies like Hershey’s and Cadburys moving more toward the premium chocolate industry. Fifth driving force is the regulatory influences and government policy changes because larger chocolate manufactures are seeking a redefinition in the word chocolate under USFDA guidelines so that they could purchase cheaper versions of the product and still call it chocolate. Six and final driving force is changing societal concerns, attitudes, and lifestyle. People nowadays are more focused in the way they eat and are more concerned with their diet. Organic chocolate is a major topic and now dark chocolate is becoming more popular because it had been proven to be healthier than milk chocolate cause of their heart-healthy anti-oxidant. 2. Roger’s Chocolates competitive strategy is basically focused on their rich and long lasting history of their company. Roger’s Chocolates was founded in 1885 and they were Canada’s oldest chocolate company. Some of their products include Empress Squares, Dark Chocolate Almond Brittle, Marquis Assortment, Collectible Gift Tins, Fruit Nut Collection, and Ice Cream products. Their industry position is not where they hope to be, because of stiff completion from Godiva, Bernard Callebaut, and Lindt. One thing that management has done is focus their high quality hand wrapped chocolates which include Victoria Creams and they have also introduced their specialty items such as chocolate coved truffles, caramels, and orange peels. Roger’s Chocolate has introduced their line of sugar-free chocolate which opens up their market to people who cannot eat that much sugar like diabetics. Roger’s Chocolates functional strategy and tactics need to improve to be aligned with their competitive strategy, they should not only pride themselves in the uniqueness of how they specially wrap their chocolate they need to be more competitive within their industry by offering more selections of their products like fat-free products or market themselves better like Godiva does when you join their membership for free, every visit when you buy something Godiva gives you a free truffle. Something like that is what Roger’s Chocolates need to focus more on. 3. The action that Steve Parkhill should undertake to improve Rogers’ competitiveness in the Canadian Premium Chocolate Industry is focus more on what their customers want from the product. It is nice and everything that Roger’s Chocolates comes nicely packaged but the majority of the people are not interested in that part, though it does bring attention to the product. The taste of the chocolate is what is important and the ingredients it comes from as well. He needs to see what is it about their product that could give them the competitive advantage of their competitors. Also in terms of culture, although Canada is full of tourism, they need to establish themselves in other places where there are high volume of people that like premium chocolate. Expand their products towards the United States where people go visit like big cities. 4. SWOT analysis †¢Strengths = Premium chocolate markets grows 20 percent annually, high quality hand wrapped packages, stores are located in tourist areas (cruise ship traffic), well established in history, high quality ingredients. †¢Weakness = Name is not recognized internationally, expansion of the company is not considered, the sales agents do not provide links of their resellers to the website so customers do now know all the places that sell Rogers’ chocolates, do not sell my the majority to their customers †¢Opportunity = Expand their products to the U. S. or internationally, become a public company to get more exposure, produce organic items †¢Threats = Hershey’s and Cadbury moving towards the premium chocolate market, many competitors (like Godiva) , Board members do not want to grow, potential selling of the company to investors, post 9/11 tourism is slowing down. The future for Roger’s Chocolates looks like it is going to stay steady with no real big changes coming in the future. They will keep their rich history going but it does not seem like anytime in the future Roger’s Chocolates will be expanding their business. 5. At first Roger’s Chocolates was in a strong financial position due to the fact that the company was privately held and did not have to deal with public shareholders. But just after the current shareholder acquired the company, growth had substantially slowed down in the past years. Tourism has fallen down a lot as well since September 11. 2001 and the decline of the dollar has not helped much the financial either. Roger’s Chocolates level of profitability is doing well with Canada’s market for chocolate being $167 million dollars annually that is a big chunk of the market share for Roger’s chocolate to work with. Their liquidity seems to be doing well, Roger’s chocolates has strong resources in keeping their facilities and raw materials working well. Though there is a lot of room for Roger’s Chocolate to expand they seem to be operating at an average level.

These materials are having a negative effect on the humane body and the environment which required to have a strict procedure to control such materials in production of the oil until handing these the concentered NORMs during the transportation from one point to another. In this report, I will be covering the definition of the NORMs and how it can be detected on the process side with a real measurement example. Also, if these materials are present, how can we mitigate these effect of exposure to the radioactive materials? According of the ADNCO Code of practice (COPV2-09). Literature review: NORMs are covering all the naturally occurring radionuclides and presenting at different concentrations in the earth crust. Moreover, these materials can be enhanced in the concentration due to the process accumulation which is associated with the recovery of oil and gas such as separators reflux pumps. This enhancement process of NORMs called TENORM (Technologically-Enhanced Naturally Occurring Radioactive Materials). The sludge, pipe scales and drilling mud are an examples of materials which can contained the elevated levels of NORMs. There are two main types of NORM contamination at Oil GAS industry which are Radium and Radon (Rn-222) contaminations. The Radium is existing in water and low specific activity scale. Moreover, the radon is usually found on natural gas production wells. Furthermore, there are two systems of measuring of radioactivity and radiation levels, which are international system (SI) and the traditional US unites with its conversion factors between them as shown in the below table: Application SI units US units-Old system Conversion Factors Radioactivity Becquerel (Bq) Picocuire (pCi) 1Bq=27pCi Concentration Becquerel/Gram (Bq/g) Picocurie/gram (pCi/g) 1Bq/g=27pCi/g Surface Activity Bq/100 cm2 Disintegrations per minute/ 100cm2 (dpm/100cm2 ) 1Bq/100cm2= 60dpm/100cm2 Exposure Coulomb/kilogram (C/Kg) Roentgen (R) 1C/KG= 3876R Dose Equivalent Sievert (Sv) Rem 1sev=100Rem Table 1 : Units of Radioactivity and Radiation Levels NORM can be divided in three types of radiation as shown below: Radiation types Definition Health Hazards Controls Alpha Particles (ÃŽ ±) -Ra-226 -U-238 -Po-210 -Pb-210 Radiation is made up of heavy, charged penetrate that cannot penetrate very fare, even in air Internal health hazards through inhalation, ingestion and absorption exposure routes skin Beta particles(ÃŽ ²) -Ran-228 -Pb-210 -Bi-210 Radiation consists of lighter charged particles than alpha particles that travel faster and are thus more penetrating than alpha radiation. Internal health hazards through inhalation, ingestion and absorption exposure routes Shielded by thin layer of metal or plastic Gamma rays (Y) -Ra-226 -Pb-210 Radiation consists of high energy rays and is very penetrating External health hazard to human bodies Shielded by thick layers of led or other dense materials including meter of concrete or several meters of water. Table 2: Types of Radiation Figure 1: Penetration power of ionizing radiation On the other hand, the health effect of these NORMs are vary with four factors which are: Total amount of energy absorbed Exposure duration Dose rate Particular organ exposed. The exposure to the NORM is not comparable with the man-made sources such as the X-Ray. A chronic exposure to these NORM without using any PPE (personal protection equipment) which is adequate to the existing radiation increases the likelihood of gaining cancer. During oil gas processing stage, the TENORM will be accumulated on two different forms as shown below: NORM in Scale Radium, one of the naturally occurring nuclides in the uranium decay series co-precipitates with strontium, barium or calcium as sulphates or carbonates and deposit on the internal surfaces of the oil and gas facilities. The formation of the scales eventually effects the integrity of the equipment, vessels and pipelines and consequentially reduces the capacity of the process facility. NORM in Sludge and Scrapings Radionuclides, mainly radium are found in sludge, produced sand and produced water. Other nuclides such as lead 210 and polonium 210 can also be found in pipeline scrapings and the sludge accumulation in lower level of the tank of gas oil separators, dehydration vessels and pipeline scrapings. Figure: 2 illustrate the NORM exposure routes to the human body as shown below. Figure 2: NORM exposure routes Referring to ADNOC COPV2-09, the NORM management process cycle has been developed and illustrated as shown below chart: Figure 3: NORM Management Process Cycle, enhanced (more details) chart The NORM management process cycle is giving a workflow how can we handle these materials if it is detected on the Oil Gas process, which basically is having an actions and controls to eliminate the effect of these radioactive to the workers, public and the environment and make it As Low As Reasonably Achievable (ALARA). Thus, before implementing the management process cycle, NORM Management Strategy was establish to make the process cycle more effective and it is consist of five keys area as follow : NORM Survey and Monitoring Workers protection and Training Control of NORM contaminated equipment Control of NORM Waste Development of NORM Management procedure. Figure 4: Norm Program strategy For any newly finished oil / gas producer well, the initial (baseline) survey shall be conducted for NORM and if the result is positive more controls and actions shall be implemented through the NORM management process cycle. Radiation Protection officer (RPO) shall be certified and having adequate competency to locate assess the radioactive on-site. The normal duties of workers don’t include exposure to NORM radiation. They are considered as members of the public. The ADNOC limit on effective dose received by any employee, shall be not exceeding the 50mSv in any single year during with a 100mSv over the 5 years. Otherwise, the worker with more dose than 50mSv/year shall be consider as classified radiation workers. Those workers shall have a periodic medical surveillance in order to insure the fitness and health. Moreover, the location/equipment can be classified in to three zones depending on the dosing values as shown below table: Dose ( µSv/Hr) Definition Requirements Unrestricted Area -Normal Work Permits -Basic Approved PPE -Good Hygiene 0.5 – 1.5 NORM supervised Area -Work to be supervised by PRO -Use NORM applicable PPE(according to standard EN 149 FFP3) -Control public access by PRO -Demarcation with warning NORM sign -Train workers -Monitor NORM levels before and after work completion -inform HSE focal points -Permit to work required 1.5 – 4.5 NORM Controlled Area (restricted) -Stop the work -inform line manager and PRO for further instruction -Control worker access b PRO -Demarcation with warning NORM sign -if dose rate exceed 4.5 µSv/hr, workers exposure must be controlled below the annual exposure of doe rate of 20  µSv. Table 3: NORM Area Classification for Non-Classified workers Methodology Hence, the NORM measurement can done through two types, either by field or laboratory measurements and both of have its own requirements and conditions. However, in this report, the field measurement will be carrying for a gamma radiation in different locations. So, the instrument was used for this measurement is the 900 series mini monitor probe type 44A in counts per seconds-cps. This meter is a very sensitive gamma rays and it is detecting the radiation as a number not level concentration. The methodology of the survey as presented below steps: Carry out initial survey beyond the site boundary to measure background radiation levels in cps using contamination meter as mention above. Hold the probe close to the surface to be surveyed, moving slowly over the area noting any response from the contamination meter and compare the background levels. If the measured radiation levels are found twice the back ground levels, measure dose-rate ( µSv/h) at a distance of 1 meter from the contaminated equipment using the dose rate mete. Measure NORM at different positions of potential NORM contaminated equipment at three different heights and average of the three readings at each height. When surveying cylindrical shape, the inside of the pipe should always be checked by placing the probe a few centimeters inside each end and record the results. Figure 5:900 series mini monitor probe type 44A Findings: The process of measuring the NORM was done by a expert third party (M/s Aberdeen Radiation Protection Services) in different locations at upstream of the oil and gas well producer, but the below table is showing only the risky data which required to have a more analysis on the amount of the gamma radiation emitted at these points. Area 1 Plant No1 Location Value of measurement Produced water pump pipe work. 100 cps Max. External surface of empty storage tank 30 cps Inside this tank adjacent to manhole entrance 200 cps External surface of base of Separator V0311 200-300 cps External surface of base of Separator V0312 140 cps Open drain Grill 30 cps Area 1, 12 well inlet at manifold Background reading, No radiation External surface test separator 110 cps All the reading are in counts per second and most of them are above 100 counts which is reflecting that it is required to have more analysis by using external dose rate meter to know the exact concentration and exposure dose to surrounding which can be emitted. Moreover, the laboratory measurement shall be one of the option to have more details by using the radiometric analysis device. Conclusion and Recommendation To sum up, the naturally occurring radioactive material are associated with oil and gas industry which shall be controlled in order to reduce the negative effect on the workers, public environment. The process of evaluating the NORM (specially the baseline) is very critical and it can be led to catastrophe condition if the outcomes are not reflecting the actual situations. This finding of Gamma rays in our case are indicating there is an industrial hygiene issue to the worker which required to have more control on the PPE and exposure duration. However, these reading are located mostly on oil separation side (upstream), however, the downstream, gas processing industry is very important point to be assessed which was missed during the third party assessment at upstream feed. In order to reduce the amount of exposure, the worker shall be following the ADNOC COPV2-09 as a guidelines such as monitoring, workers protection requirements and transport of NORM contaminated equipment. Moreover, the Gamma elements will be moving from the upstream to downstream which will be reaching the gas processing units. So, it is recommended to have regular inspection for the radioactive materials specially the glycol unit will observed most of the moisture on the process which can be containing the radiation elements.

Deforestation Cause and Effects

Deforestation Cause and Effects Modern predictions and indicators paint a bleak outlook for the planet and unfortunately it is all due to human actions. Deforestation and the spread of barren, arid and useless land is increasing in pace and we are the only ones who can call it to a halt. The questions that need answering quickly before it is too late are how and when. When is obvious, unless we act immediately we will be too late, how is less clear but unless we find the answers soon then we could find ourselves left with nothing but a arid infertile desert of a planet and sooner than you might think. Perhaps we can blame the men who cut down or burn huge swathes of forest and watch the animals flee to die of starvation after their home and food supply has been destroyed, or those who profit from their actions. Only someone who was insane would do such a thing surely? You certainly wouldnt want to be associated with those that were involved in such wholesale destruction and slaughter and certainly wouldnt be involved yourself, right? Deforestation for Profit Forests contain many valuable natural resources and the land they cover is also valuable to an ever-increasing human population. People have been making use of these resources ever since we first appeared. Deforestation is a way of making a living, the timber can be sold, and the land can be used for growing crops or grazing herds or to provide land for homes and businesses. Why is this allowed to happen? Those people that are entrusted by us with the planet are those who are destroying it. Governments give permits and licenses to those who have the money to buy them they then strip the land and make their money. The governments are often poor and the land is more valuable to large corporations than used for conservation and tourism. But these governments are selling off the planets life support system and that cannot continue. We may be frustrated in the face of such insurmountable obstacles but we can challenge these large corporations by refusing to buy their products and lobby governments to protect forested areas. If enough people say no then they will be forced to act. The planet has been entrusted to all of us and it is up to us to save it even now at the 11th hour it isnt too late. Even small actions if done by enough people add up to a massive effect. Reversing Deforestation Nature on the whole is resilient and bounces back extremely fast if given the chance. However forests are slow to re grow and mature. Once the soil has been eroded it could take centuries for it to build up again and start supporting anywhere near the diversity of life it once did. Millions of species have been wiped out never to be seen again in fact most were never seen by human eyes before being driven to extinction. This does not mean we should not try to protect and restore these amazing and diverse habitats, which do so much for us and ask only to be left to exist in return. What is Deforestation? In recent times, mankind has felt the wrath of nature. More and more natural disasters are taking place due to human induced climate change. This has lead to an increasing awareness of our impact on the planet we call home and its natural resources. Forests are some of our most abused habitats due to the fact that wood is a raw material with a wide range of uses and fill virtually al of our basic needs particularly food, fuel and shelter. Another important influencing factor for deforestation is the need for more land, so forests are cleared to make way for industrial development, housing or agriculture (either livestock or crops) or even a dump. By Definition Deforestation is the clearing or removal of trees from an area of woodland or forest for many differing reason usually commercial. Deforestation usually doesnt apply to cases where the trees are replaced, usually as saplings, in the same or alternative location in order to replace those that were cut down. Also usually refers to large scale clearing of whole areas rather than limited or selective clearing. Man has cut down trees since we first appeared, changing and adapting the environment to suit our needs in order to provide the things we require to live successfully. For kindling, shelter, weapons and in more modern times paper, furniture and housing. Thousands upon thousands of acres of forest have disappeared worldwide to fill our insatiable appetite for wood and land, yet they also have to meet the demands of the vast majority of the worlds other species both plant and animal. Raising Consciousness Humans are roused to action when an issue directly affects them. This is undoubtedly the reason people are more aware than ever of the effects of deforestation as more and more people become affected by climate change and extreme weather events. It is these effects that are the most effective way of showing people the benefits forests provide and why it is so vital the little we have left be protected at all costs. The depletion of the forests has a number of detrimental effects on the environment and climate. There are two main thrusts to this argument. The first is the environmental services that forests provide such as maintaining our atmosphere and slowing global warming and protecting us from floods. The second is the need to ensure a reliable and sustainable supply of natural resources. I.e. if they are being used and managed properly and ensuring reforestation occurs. First the environmental benefits forests help maintain the balance of gases in the atmosphere particularly oxygen and carbon dioxide. The trees ability to take carbon dioxide out of the atmosphere and trap it is our most important weapon in the battle against climate change. Cutting down and burning trees releases the green house gas back into the atmosphere worsening the problem. It is these green house gases that are causing global warming and extreme weather events. In many cases the timber is simply burned to clear the land quickly which is the worst possible thing to do especially when it could be put to good use providing for those who might be in need of it. Finally woodland traps water and act as sponges when water levels are high reducing the chances of flooding. Why does Deforestation Happen? We are now learning the consequences of trying to battle against nature, yet change is slow and we are still abusing the natural world. With our knowledge we should be doing all we can to stop further deforestation so why does deforestation continue despite the harm we know it does to the environment and thus ourselves? The answers are not straightforward but undoubtedly lie with us and our desperate need for the resources the forest provides. The needs of a massive human population have to be met daily putting the natural world under enormous pressure. We constantly look for new ways to get what we need faster and more efficiently. But the more efficiently we exploit nature the quicker natural resources are used up and disappear. This leads to new ways of getting what we need or finding new resources to exploit depleting the natural world even faster, its a vicious cycle that leads to the devastation of our beautiful planet. The Global Man Made Phenomenon Man has been clearing woodland since ancient times but it is recently in the last century that the worlds forests and rainforests have been dramatically reduced shrinking in size year on year at an ever more furious pace. Until fairly recently there was little real opposition from the public or government as the seemed to be no real viable alternatives and so it continues to this day. Land is a finite commodity in a world with an ever-growing human population. Developed land is worth far more than forest so the forest is clear to make way for large-scale development and agriculture. Wood is unfortunately worth nothing standing growing in a forest but far more as a piece of paper, furniture or even a house. Profit driven by the high demand for these resources is the reason these forests are disappearing. There are many resources which can be gathered from the forest such as food and medicines though the main product is wood which has a wide variety of uses from paper to a building material and even as a fuel. With lumber having such a number of uses and a strong demand then it should have a strong impact on economic growth. But forest values are actually falling, a surprising trend given that forests are fast disappearing and mans propensity towards exploiting limited resources for profit. Why Does Deforestation Result in Devastation? Experts dont see deforestation as an all-bad thing as long as it is done in an environmentally sensitive and sustainable way. It is a matter of careful controlling how and where you clear areas of forest. A small area of clearing provides opportunities for opportunistic species and is quickly recolonized and breaks in the canopy quickly filled. Large areas take longer to recolonise and separate areas of forest previously joined. They also allow the wind and rain to erode the soil making recolonization by forest plants much harder. Rain forests typically have very thin soil which is held in place by the roots of the giant trees and with out which quickly disappears. Wildlife that lives in the forest cannot survive in the open and so has to retreat with the forest or if it cannot die. Under the canopy is a moist dank warm environment as the plants trap the heat and moisture from escaping, without these very specific conditions, which exist in few other places many species are unable to survive. So who is the culprit? You we all play a part in deforestation to a lesser or greater degree though the choices we make when shopping daily. We cant point the blame solely on governments and big corporations though they certainly play a big part but it is our willingness to block out the knowledge of where the things we buy come from and how they are produced that means they can carry on destroying the earth and it is unlikely to stop until we make it with our consumer choices. Effects of Deforestation Humans have always and probably always will depended on forests to a lesser or greater degree. Trees provide food, shelter from the elements and predators not just to humans but the vast majority of life on land. Unfortunately the forests resources and appeal is its downfall. Deforestation is probably one of the greatest challenges we face. We need the forests to maintain the atmosphere alongside the burning of fossil fuels our destruction of the forests is a major contributory factor to the rising levels of carbon dioxide and global warming, the effects of which we are only now beginning to feel. Large-scale deforestation for agricultural and industrial purposes transforms rich and diverse habitat in barren arid land. The resources are quickly repeated and another massive are of forest has to be destroyed to provide yet more. The damage to the land and soil has been done and little can grow on these areas once they have been finished with. Deforestation needs to be stopped before we end up with a planet that is little more than an arid wasteland incapable of supporting life. Effects of Deforestation on the Environment Rainforests are the richest and most diverse areas on the planet and are home to the vast majority of the worlds species, many yet to be seen or classified by science. Any one can wander into a rainforest and will fairly quickly discover a new species. This biodiversity took many millions of years to evolve and can be destroyed with the swipe of a powerful saw. There is no possibility of getting back the estimated 50,000 species that go extinct every year a that is increasing. The chance to explore this forest world is disappearing fast and wont come again once its gone, a chance future generations wont thank us for denying them. Not only are countless species being lost but also the chance to increase or knowledge of the world, chemicals and medicines unknown to science are out waiting to be discovered. The preservation of the rainforest also means the chance to explore these opportunities and make new discoveries and advance human knowledge. Effects of Deforestation on Society The indigenous people, whose home and way of life is turned upside down by the arrival of the lumber lorries, will feel much of the effects of deforestation. They survive by living in harmony with the forest and its inhabitants but are often forced to leave or change their way of living in order to survive. This displacement of people and the consequent loss of that culture makes the human race a little poorer. Those that live on the edges of the forest are also affected, as they can no longer gather resources from it for themselves. These people are unused to living in towns and cities a totally alien culture and are unlikely to have the money, skills or education to make a decent living having learned to live off the land. Nature cannot be completely replaced by our own efforts even after all our recent advances in technology she does it better than us. Nature serves us in far better ways than the best designed structures and industry, yet we treat her with nothing but contempt and unless we stop the consequences will be dire. Deforestation and Climate Change Throughout history forests have spread and retreated as the environment changed now they are fast disappearing. They shelter the vast majority of land animals and hold most of the land biodiversity. These beautiful and complex ecosystems are essential to the environment and help to regulate the atmosphere. Hence deforestation and climate change are closely connected and have the ability to control one another. Unfortunately the forests, which should be our first line of defense against rising carbon dioxide levels, are vanishing rapidly. 80% of our previously forested areas are gone drastically reducing the planets ability to absorb carbon dioxide and contributing to the high levels of the green house gas by releasing it after being cut down making the situation worse. The fact that deforestation can further affect the atmosphere should stir us into action to prevent any further reduction in the worlds forests. We will just be adding to the devastating effects of climate change if we dont take action to stop further deforestation. Major Carbon Storehouses It has become increasingly apparent that forests play a vital role in climate control by storing carbon and water and recycling it. It is a fact that the destruction of green areas is a contributory factor in climate change and eliminates their ability to regulate the climate. It has been estimate the 18% of all carbon emissions come from deforestation and we are effectively turning our prize weapon against global warming against ourselves instead. Mature forests are the largest stores of carbon dioxide though all plants store carbon. Other stores include the soil, vegetation frozen underneath the arctic permafrost even the algae in the sea. The world largest forests such as the Amazon represent our largest carbon stores, its destruction would undoubted lead to quick and devastating climate change. Carbon is released from plant life through burning and natural decay. Burning releases the carbon much faster and more efficiently than natural decay or rotting. If left to nature plants will rot slowly especially large trees and the carbon is often buried and the carbon trapped below ground where it slowly fossilizes to produce various compounds depending upon the conditions ranging from diamonds to fossil fuels over many millennia. This whole process traps the carbon and prevents it entering the atmosphere. Deforestation prevents this natural process from taking pace. Climate Change A combination of deforestation and the burning of fossil fuels releasing much larger amounts of carbon dioxide in the atmosphere than would occur naturally whilst simultaneously disabling the planets ability to absorb and cope with this influx in green house gases has lead to the current climate changes and noticeable global warming. The main effects of climate change have been a rise in temperature throughout the year leading to widespread environmental change species moving their ranges further north to follow the increase in temperature. Melting of the polar ice caps leads to a reduction in range for polar species. A consequent rise in sea levels leads to flooding of low lying land. More violent and extreme weather systems lead to the devastation of affected areas and causing huge loss of life. This isnt a prediction of what will happen in the future its happening now and maybe irreversible already. So now an immediate damage limitation exercise need to take place to ensure the climate doesnt get out of control this has to involve the protection and restoration of the worlds forests.

Jamaica, Trinidad, and Guyana as Free Labor Colonies :: American History Historical Essays

Jamaica, Trinidad, and Guyana as Free Labor Colonies Introduction The main concept of this paper is to show how Britain turned three of its colonies (Jamaica, Trinidad, and Guyana) into "free labor" colonies after gradual emancipation of slaves was introduced in 1833, and full emancipation was accepted in 1838. British West Indian colonies could be put into two categories: established colonies and new colonies. Jamaica had officially been a British colony since 1670, while Trinidad was converted to British rule in 1802 and Guyana in 1814. The age difference between the two categories resulted in different situations for the colonies and that is what will be discussed here. Before Emancipation At the end of the 18th Century into the beginning of the 19th Century, Britain was moving toward industrialization, which in turn led to a movement towards free labor from its citizens. Britain was also expanding is enterprises within it’s East Indian Trade Company. The East Indian countries had the raw materials that the new textile industry needed. Free people are also a better market for the textiles than the slave populations of the West Indies would. [1] The movement towards industry and Britain’s concentration in East Asia hindered the sugar plantations in the Caribbean. All of this caused a movement towards emancipating the slaves in the Caribbean. But the movement towards industrialization increased the need for sugar. [2] When the slaves were freed, Jamaica, Trinidad, and Guyana all had to deal with the new need for labor. Jamaica was already an established sugar producer and was at one point the jewel of the British West Indies. Jamaica was not a crown colony, however, and was organized by independent citizens, while Trinidad and Guyana, on the other hand, were recently acquired Royal colonies and had different economic circumstances than Jamaica. [3] Jamaica was about 2,848,000 square acres of land and only one quarter of land was unfit for cultivation. An estimation of about a quarter of the land was cultivated and only about a third of the available land was tilled in 1842. [4] Trinidad was considered the most fertile of any of the British colonies and second largest island after Jamaica. Of about 1,400,000 acres, it was estimated that only one-thirtieth part was unfit for cultivation; but not more than 209,000 acres had been appropriated, and of these less than 44,000 were under tillage. Sugar-planting had been a few years in operation when the island came into out possession in 1802.
