Evolving evolution Essay Example | Topics and Well Written Essays - 500 words

Evolving evolution - Essay Example The article offers the three constructs of Darwinian theory that include natural selection, heredity, and variation. Darwin believed that evolution was a gradual process where randomized changes to genetic profiles occurred while the organism sought â€Å"favorable variations† (Rosenfield & Ziff, 2006, p.1). Thus, Darwin believed that evolution consisted of unpredictable conditions that would best suit the organism for adaptability to a changing environment. However, advancing researchers such as Mendel began to recognize tangible genetic characteristics in organisms that were directly related to evolutionary changes with a new emphasis on genetic heredity. Not wanting to completely refute Darwin position, a new variation on Darwinian theory known as Modern Synthesis was released in the 1940s that began to recognize genetic importance in evolutionary patterns. Brakefield (2006) refers to the neo-Darwin knowledge of genetics as a catalyst for what Darwin believed as random muta tions as genetic morphology, the real constraints on classical natural selection theory. The article then describes further contemporary knowledge of the nature of the double helix as an explanation of how biological mutations occur, which in this case supported Darwin’s view that evolution occurs over time. The article describes Darwin’s view on the complexity of the eye as a means of describing certain knowledge inconsistencies during Darwin’s time period in an attempt to ascribe eye evolution to his classical view of natural selection. Offers Lamb (2011), a contributor to Scientific American, the eye is often regarded by opponents of evolution as â€Å"a system that cannot function in the absence of any of its components and therefore cannot have evolved naturally from a more primitive form†. Darwin, himself, argues that such complexity makes it difficult to support classical evolutionary theory, but acknowledges that elongated periods of time made such adaptations probable

Risk and Mental Health Coursework Example | Topics and Well Written Essays - 8000 words

Risk and Mental Health - Coursework Example Risk definition, assessment and devising strategic approaches,tactics,models and even algorithms to deal with each of these specific risks on either stand alone or grouped basis has turned a major concern for the medical care providers dealing with cases of mental health. The task becomes formidable as the incidence of such mental health cases is substantial in most jurisdictions. Take the instance of incidence of traumatic brain injuries or even mild traumatic brain injuries. Globally millions of affected persons are treated each year for severe head injury. (Jennett, 1996) Various best practices guidelines have defined head injuries. National Institute for Clinical Excellence has the following definition: 'Head injury' is defined as any trauma to the head, other than superficial injuries to the face. (National, 2003) Of the millions hit by head injuries each year; the most common incidents causing these injuries are falls, road traffic accidents and assaults (such as fights). Youth (15 years and over) and children are more susceptible to head injuries due to an active and mobile lifestyle. However most of the sustained head injuries are diagnosed mild and do not lead to admission as in-patients. About nine out of ten people seen in hospital have a mild or minor head injury and will go home without being admitted to hospital. This itself may be an indication of gross under evaluation of the risk associated with the mental health of the patient. However the illness states f these patients is technically termed as mild traumatic brain injury (MTBI).MTBI patients, even if admitted to hospital, are discharged within of after 48 hours. Only a fraction of the total number of people who have had head injuries (often placed at lesser than one in a hundred) do suffer from a severe injury to their brain. The general argument offered is that the severe brain injury is rare as the scalp and skull of human head play protective roles and absorb much of the impact of the inj ury. However symptoms including bleeding swelling or bruising can occur both inside the skull and inside the brain. Where the damage is located and what has been the extent of such damage is decided by the force and speed of the blow. Therefore, it is often said that a timely and speedy treatment of a severe injury to the brain may result in complete recovery; however, no medical care system can guarantee against serious disability or even fatality as a result of such severe head injuries -particularly if the treatment is delayed and/or misplaced as well. (National,2003).All such cases present themselves as living examples of deficient treatment of risks involved in mental health situation. To make the matters worse, and continuing with the most extreme and delicate state of mental ill health i.e. traumatic brain

The Sarbanes-Oxley Act: Protecting Corporate Assets Essays -- SOX Act,

Internal Controls. Kind of like a brick wall, or a fire wall on a computer. Internal controls act as a way to keep a company and its assets safe, as well as make sure that the company maintains complete and accurate accounting records. Internal controls are in charge of the overall well being of a company from its assets to its employees, even to its sales and reputation. A lot of things are involved with internal controls such as; Sarbanes-Oxley Act, stock well being, well being and safety of assets and accounting accuracy. One of the Internal Controls main purposes is that of keeping a companies assets safe, whether that be from employees, robbers, or misuse from outside parties. As one can figure keeping a companies assets would be a very important task that would keep a company running smoothly and successfully if all went well. Internal Controls will work to maintain the safety of all assets of a company by assuring no unauthorized use or access, and keeping close watches over all records and information. Another main task of the internal control is that of keeping the accounting records up to date and accurate at all times. In the past months there has been quite a bit of emphasis on the importance of a company keeping complete and accurate accounting records for many reasons. A companies well being may depend on its records accuracy, if there happen to be a problem spotted a simple solution would be to revert back to the records, but what if the records are inaccurate, or incomplete? It is extremely important that Internal Controls keep close watch over the accuracy of the companies accounting records of all forms. The Sarbanes-Oxley Act of 2002 or SOX was created by the governments sector of Public Compan... ...d to companies loosing billions of dollars to those unethical practicing members of a company. As one can see internal controls in a company can make or break a company. With all participation and strict principals internal controls can provide a great basis for a company and catch all errors to ensure a smooth run for a company and avoidance of any scandals. With a loose internal control system or unethical practices a company can get a bad wrap, loose customers and investors, loose profit and assets, as well as loose all reputability. There will always be problems within companies, but with the close running of a company’s internal control and ethical practices, government involvement, and outside audits and over views a company can lower their risk of loosing anything valuable to their company, and staying out of the public’s eye in a negative manner.

Betrayal in the city Essay

A critical analysis of the theme of betrayal in Francis Imbuga’s Betrayal in the City, Game of Silence and Man of Kafira This study examines the kind of influence postin dependence realities have had on Imbuga as a playwright. More specifically it is an exploration of some aspects of Imbuga’s dramatic transmission of these realities. A critical analysis of the dominant theme of betrayal, in Betrayal in the City, Game of Silence and Man of Kafira helps illuminate the realities. The guiding assumption is that drama in Africa carries a political dimension and is therefore socially committed. Drama may thus be read as a barometer of social change and progress. Imbuga’s drama artistically presents topical socio-political issues through dramatic exploration of the theme of betrayal and in the process reveals the playwright’s perception of society. The analysis starts off with a survey of the historical background of the three selected plays. This way we arrive at the origins of the theme of betrayal. The physical setting is Africa where the goings-on include the strangling of nascent democracy and the attendant oppression of the common people by the ruling elite. As Betrayal in the City demonstrates, the consequence of this state of affairs is a popular desire for change. Game of Silence is a dramatic critique of the culture of silence in which the playwright seems to advocate popular reaction against autocratic and anti-life forces. As Imbuga’s ideological stance as a writer becomes clearer in this play, we advance into Man of Kafira and its dominant theme of power crisis and the related positions of the former head of state. In the final analysis, we have read and understood society through Imbuga’s drama.

The Legacy Of President Reagan - 1066 Words

One of the best presidents in the U.S. was Ronald Reagan. He was characterized by the love he showed to the country, many even considered him a hero. Reagan prove the American population what a true president is and what to expect of a president. Furthermore, he had a great communication with individuals and just by saying one word he could persuade the whole nation. When Reagan became president he was sure on the things that had to be done for the country. He compromise on the cut of taxes, curb government spending, and balance federal budget or at least reduce the deficit (Cannon, 2015). These goals would forever determine his administration. When Reagan came to power he was confronting a serious economic crisis and he knew that the†¦show more content†¦He knew that the cut of taxes would create an increase in supply and demand. This bill was mostly beneficial to the supply side of the economy. Many businessmen were able to invest in the country due to the tax reduction the country was facing. For instance, the economy of the U.S. would shift up and become the world potential power. When a big nation such as U.S. has an increase in supply, countries with a lower GDP want these kind of nations to help in the increase of their economy. When you start trade with these countries it can be beneficial to the growth of the country. Some of t he things such as vegetables can be cheaper in another country and therefore can be traded to the U.S. The Reagan years brought annual real GDP growth of 3.5% to 4.9% after the recession (Smith, 2014). Another important achievement in Reagan’s administration was the Water Quality Control Act. Reagan thought that the lakes had too much wastes and were polluted it was the government responsibility to clean the lakes. For Regan it was important to clean American waters because it was beneficial to each individual. The cleaning of American water was one of the highest goals Reagan wanted to achieve. This showed the humanitarian part the president had. In the days they were living not everyone thought it was important to take care of the lakes. Reagan not only showed a noble character but he also demonstrated what he was willing of

Using Early Release Credit Programs - 832 Words

Do Nothing Prison administrators, backed by legislatures, can continue to utilize early release credit programs without policy changes. The continued use of early release credit programs would provide a reduction to overcrowding. However, in continuing to use current early credit programs, legislatures are not addressing public safety concerns and the lack rehabilitation. Offenders are being released into society far too early to enable them to perform restitution and undergo rehabilitation. Take an Incremental Approach An open dialogue would be required between the legislature, department of correction personnel and the public. This dialogue would provide policy changes to the early release credit programs that focused on the reduction in prison population of non-violent offenders, establish rehabilitative programs to provide re-entry guidance and most importantly, always keep public safety at the forefront of the discussions. â€Å"The earned credits are viewed as incentivizing inmates to participate in rehabilitative programs that, in turn, should reduce recidivism after release from prison† (Turner, 2011). The prison system should not be viewed as a warehouse for humans but rather as a much needed form of justice that provides public safety by removing violent offenders and rehabilitating those that are deemed non-violent. All parties involved should take note that the major flaws in credit programs are not the programs themselves but rather the lack of accoun tability andShow MoreRelatedTeen Pregnancy Is A Serious Problem1484 Words   |  6 Pagesoften.

Rhetorical Features of Lyndon B. Johnson’s Presidencial...

In the fall of 1963 Kennedy’s Administration was preparing campaigns for the election of 1964 in hopes of bringing the fragile Texas Democratic Party closer. The Kennedys headed to Dallas on the morning of November 22, 1963 to attend a scheduled luncheon. On that tragic day President Kennedy was assassinated in a senseless act of violence. Within the next few hours, Vice President Lyndon Johnson was sworn in as president. In the midst of a grieving country, he was given the duty of handling a transition in leadership and presenting an acceptance speech before Congress. LBJ gave his acceptance speech of the U.S. presidency in front of Congress just five short days after John F. Kennedy had been assassinated. Expectations were high but then†¦show more content†¦Vulnerability may be seen as a weakness in a leader’s character, but in these rare circumstances of sudden death these feelings are to be expected in a state of shock. Within the President’s message he also employs an additional rhetorical feature in regards to its deliberative genre. Johnson spends a great deal of the speech explaining political plans and goals for America’s future. He also clarifies that he will â€Å"continue the work of President Kennedy.† The significance of this is that he has revealed his future agenda as well. By vowing to carry out the agenda of the Kennedy administration he is making a case for his assumed role of responsibility to keep the country in a forward movement. The deliberative genre here benefits his situation because he is demonstrating his hands-on approach to the sudden presidency bestowed upon him. A second example of the use of deliberative genre is when Johnson takes a stance on how the country will access nations abroad. He declares that â€Å"Those who test our courage will find it strong, and those who seek our friendship will find it honorable.† Here President Johnson has taken a stance against any doubts that America would not be able to handle such a tragedy in a graceful manner. This handling of words cultivates a positive and preserving attitude about America as a leading nation and loyal government. Lyndon B. Johnson’s timeliness in
