In the mid 19th century english naturalist Charles Darwin - who has been called the "father of evolution" - conceived of the most comprehensive findings about organic evolution ever . Today many of his principles still entail modern interpretation of evolution. I've assessed and interpreted the basis of Darwin's theories on evolution, incorporating a number of other factors concerning evolutionary theory in the process. Criticism of Darwin's conclusions abounds somewhat more than has been paid tribute to, however Darwin's findings marked a revolution of thought and social upheaval unprecedented in Western consciousness challenging not only the scientific community, but the prominent religious institution as well. Another revolution in science of a lesser nature was also spawned by Darwin, namely the remarkable simplicity with which his major work The Origin of the Species was written - straightforward English, anyone capable of a logical argument could follow it - also unprecedented in the scientific community (compare this to Isaac Newton's horribly complex work taking the scientific community years to interpret ). Evolutionary and revolutionary in more than one sense of each word. Every theory mentioned in the following reading, in fact falls back to Darwinism. DARWINIAN THEORY OF BIOLOGICAL EVOLUTION Modern conception of species and the idea of organic evolution had been part of Western consciousness since the mid-17th century (a la John Ray) , but wide- range acceptance of this idea, beyond the bounds of the scientific community, did not arise until Darwin published his findings in 1958 . Darwin first developed his theory of biological evolution in 1938, following his five-year circumglobal voyage in the southern tropics (as a naturalist) on the H.M.S. Beagle, and perusal of one Thomas Malthus' An Essay on the Principle of Population which proposed that environmental factors, such as famine and disease limited human population growth . This had direct bearing on Darwin's theory of natural selection, furnishing him with an enhanced conceptualization of the "survival of the fittest" - the competition among individuals of the same species for limited resources - the "missing piece" to his puzzle . For fear of contradicting his father's beliefs, Darwin did not publish his findings until he was virtually forced after Alfred Wa! llace sent him a short paper almost identical to his own extensive works on the theory of evolution. The two men presented a joint paper to the Linnaean Society in 1958 - Darwin published a much larger work ("a mere abstract of my material") Origin of the Species a year later, a source of undue controversy and opposition (from pious Christians) , but remarkable development for evolutionary theory. Their findings basically stated that populations of organisms and individuals of a species were varied: some individuals were more capable of obtaining mates, food and other means of sustenance, consequently producing more offspring than less capable individuals. Their offspring would retain some of these characteristics, hence a disproportionate representation of successive individuals in future generations. Therefore future generations would tend have those characteristics of more accommodating individuals . This is the basis of Darwin's theory of natural selection: those individuals incapable of adapting to change are eliminated in future generations, "selected against". Darwin observed that animals tended to produce more offspring than were necessary to replace themselves, leading to the logical conclusion that eventually the earth would no longer be able to support an expanding population. As a result of increasing population however, war, famine and pestilence al! so increase proportionately, generally maintaining comparatively stable population . Twelve years

Attention deficit disorder and comorbidity of depression Research Paper

Attention deficit disorder and comorbidity of depression - Research Paper Example Attention deficit hyperactivity disorder refers to an assorted disorder of unidentified etiology. Attention deficit hyperactivity disorder has an effect on 3% to 6% of kids who are at the age of going to school. The danger for comorbidity with additional psychiatric disorders is elevated, and the incidence of comorbid disorders necessitates special contemplation in the management of patients who have this disorder. Little is acknowledged in regard to the comorbidity of attention deficit disorder with disorders except for conduct. For that reason, the researcher will undertake a research of the psychiatric, as well as psychological writing for empirical evaluations that talk about the comorbidity of attention insufficiency hyperactivity disorder. The psychiatric disorder presently referred to as "ADHD" has progressed significantly over time. Early conceptualization of the syndrome from the years of 1930s to the years of 1960s stressed the prospective for nominal brain injury or even dysfunction. With the introduction of the Diagnostic, as well as Statistical handbook of Mental Disorders, in the year 1968, the condition was known as "hyperkinetic response of childhood," straining on the motor features (Biederman & Sprich, 2001). As the comprehension of the disorder well on within the 1980s, attentional, as well as impetuous/hyperactivity constituents were stressed. Present DSM-IV categorization of ADHD reproduces this transformation. Three secondary kinds of the disorder have been defined within the DSM-IV, counting ADHD principally distracted, ADHD primarily hyperactive-impulsive, as well as ADHD collective type. The ADHD collective kind is the most familiar and the distracted type is atypical. Numerous assessments have esta blished that the syndrome is common universal as school-age children within all nations suffer from this syndrome. The etiologic inputs to ADHD are multifaceted and incorporate neuroanatomic aberration, neurobiologic

COE Framework And Ethical Dispositions Comparison Matrix Assignment

COE Framework And Ethical Dispositions Comparison Matrix - Assignment Example I have ranked the issue of Mastery of Content at number two because these are the fundamentals of any successful learning program. For professional educators to align themselves with facts and deliver without bias, a mastery of important concepts and principles is key. According to Mowchan et al. (2015), "Any professional service provider, in this case, professional educators, should conduct business with objectivity, avoiding conflict of interest or personal prejudice and should not intentionally mislead others, for this case students." â€Å"Learners will align educational objectives to content and professional education standards, as well as design formative and summative assessments including rubrics that analyze student learning and teacher effectiveness.† (COE-GCU Framework, 2011) I have rated Student Learning and Teacher effectiveness at number three because this relationship fosters coherence and important shared values. The professional educator can be able to understand the diversity of cultures through such formative assessments that are more certainly than not set by both parties. In a research conducted by Cannaerts et al., 2014 indicated that ethics education was best attained through ethics learning integrated through a curriculum that was learner based. Learning based on diversity of views enhances active participation that is more efficient (Ann, 2013).

History Of The Industrialised Building System Construction Essay

History Of The Industrialised Building System Construction Essay Steel framing construction is classified as one of the Industrialised Building System. However, Industrialised Building System (IBS) is common in construction industry in Malaysia. Steel framing is becoming more common in residential construction. The use of steel for framing residential construction has both advantages and disadvantages. Steel frame elements are manufactured in the factory and then will be transported to a job site for installation once it passed the inspection on it quality standard. This method has its own significance and shortage. Construction site take very high attention on the safety aspect especially when the construction is running. Safety is an issue that has no end and every year will have accidents occurred on construction site. However, it can be lead to accidence that may cause injured or dead to worker or public. Steel framing construction also having their own risk and hazard in its construction process during the installation component although it was convenient to install. For example steel column base plates are a fundamental component of a steel structure. Poor base plate installation can lead to steel columns tipping over, which can cause severe injuries or death to worker in the area. The experiences contractor on steel framing installation knows there are procedures required to pull off a high level of quality, customer satisfaction and most important safety. To make installation run smoothly it is the best to have experienced worker or else have a good safety and health management to guide and control the workers to comply with the safety rules. By the way, the major problem was poor attitude of the worker and poor management system. Aim and Objectives The overall objective for this proposal is to investigate and evaluate the safety aspects in steel framing construction. The specific objectives of this study are as follows: 1. To study the process of installation steel framing component. 2. To identify the safety aspect and the requirement during the installation process steel framing component at site. 3. To identify the level of safety during installation process at site. Problem Statement The Industrialised Building System (IBS) is not a new approach in Malaysia. It has been introduced in Malaysia since 1966. However, the most steel framing construction accidents occur because the developer or contractor lack of proper planning or using the unsafe equipments and do not follow the correct method when installation. Apart from this, unsafe site condition, not using the safety equipment that was provided, and poor attitude of workers toward safety during installation process also the issues that causes accident. Therefore, it indicated that there is lack of consideration of safety and risk evaluation in IBS construction. Based on the information from Social Security Organization (SOCSO), Malaysia recorded a worrying increase in the numbers of accident occurring at construction site. It shows that a total of 4654 out of 73858 industrial accidents recorded in 2003 were come from the construction industry. (Mohammed Taher Alashwal, 2008). But it different if used steel framing system, the statistic from CIDB shows the accidents are 50% from heavy lifting, 20% installation, 10% other factor, and other 10% from during transportation component to storage accidents. Scope of study The scope of this study is focussed on safety aspects on installation of Industrialised Building System (IBS) which specific in steel framing construction. This study is to identify the safety aspect during the steel framing construction at the installation stage. The information will be collected from observation, interviews, internet resources, journal and some of the documents. 1. This study covers Industrialised Building System specific in steel framing. 2. This study identifies the safety requirements within the installation stage of steel framing construction. 3. Information will be collected at Kuala Lumpur and Selangor area. Methodology Interview In this research proposal, interviewed is to be conducted with the contractor which are using steel framing system for their project or any other relevant position of staff within construction site to get the information. 4 to 5 interview question will be set which related to my research objective there are to identify the safety aspect and requirement during the installation process of steel framing component at site and to identify the level of safety during installation process at site. After that, I will do an summary based on the information that I collect from the respondent. Face to face interview will be conducted and several questions will be asked and the answer will be recorded down. Face to face interview is chosen because it was very convenient for the respondent and interviewee to discuss and different date collection techniques can be used for example open-ended questions and visual aids can improve the understanding of interviewee. Desktop based review To improve my understanding and experience to do future thesis, I will using desktop based review as my secondary data collection techniques which reading through the articles, journal papers, conference papers, books and websites browsing related to my title. Through this method I can have better understanding on the process of installation steel framing component before I go to the construction site visit to do observation. So when I go to the site visit, I can directly go to the point of the installation process and can easily understand the information given by the respondent to get the good idea to write my research. Review of previous research and book done by other people also make me more familiar with the correct way to do research in this topic and also increase the accuracy. Observation Besides, observation will as my one of the method to collect data to identify the level of safety during installation process at site. Besides, I also will observe on the process of installation steel framing component to fulfil my objective. I will make appointment with the contractor which using steel framing system to have a site visit at his construction site to observe the going of project specific in installation process of steel framing system. I also will take a reference on the lay out plans for steel frame component, steel frame installation guide, and other communications which provide by contractor. The important of study Through this research, the contractor which specific on steel framing construction can use this as a guide for them to review their safety requirement when installation of the steel framing component to reduce the rate of accident of construction work in Malaysia.

Criricism of Wilkie Collins’ Woman in White Essay -- Wilkie Collins Wo

Criricism of Wilkie Collins’ Woman in White â€Å"To Mr. Collins belongs the credit of having introduced into fiction those most mysterious of mysteries, the mysteries which are at our own doors.† So said Henry James in an unsigned review of another author’s work. But his view was certainly not shared by all those who cast their opinions into the fray. An unsigned review in the Saturday Review said of Collins’ work, â€Å"Estimated by the standard of great novels, the Woman in White is nowhere. Somewhere between these two points are friends and correspondents of Mr. Wilkie Collins. Novelist George Meredith wrote to Collins himself saying, â€Å"The tension of the W[oman] in W[hite] is not exactly pleasant, though cleverly produced.

He observed that, â€Å"There cannot be a doubt that it is a very great advance on all your former writing...† and also, â€Å"I seem to have noticed, here and there, that the great pains you take express themselves a trifle too much, and you know that I always contest your disposition to give an audience credit for nothing, which necessarily involves the forcing of points on their attention...† Considering all the material Wilkie Collins was either to be praised for inventing a new style, looked at in scorn for his lack of character development, or deemed the author of a work that â€Å"is an inferior metal altogether, though good and valuable of its kind,† as the Saturday Review critic stated.   Ã‚  Ã‚  Ã‚   Many critics complain that Collins’ characters are caricatures, not characters.

Literature of War and Peace Essay

Sir Winston Churchill British statesman, orator, and author who was elected prime minister twice in 1940s and 1950s. He is regarded as one of the finest military leaders in history and is credited to rallying the moral of the British people during world war two and leading them from the brink of defeat to victory against the axis powers. How he did this was not only though his leadership but arguably through his speeches as well, one of Churchill’s greatest assets was his words and how he used them to inspire and motivate his people. Despite having a lisp throughout his career He was known for his excellent speaking, the speeches he made throughout his life in particularly dark times for the British were always inspiring, while presented in a way that made them understandable to any person no matter whom they were. Now this was seen particularly in Churchill’s speech â€Å"the defence of freedom and peace† which he presented in October 16th 1938 near the start of world war two in an appeal to British and Americna public to prepare for the strong possibility of war against Nazi Germany. In the speech the defence of freedom and peace Churchill uses a variety of persuasive yet simple literary devices such as allusion, rhetorical questions, imagery and Tricolon and wording to arouse, influence and encourage American and British listeners to ready themselves for a possible war against Germany. Now prior to this speech Britain’s foreign policy regarding Nazi expansion was one of appeasement. British Prime minister Neville Chamberlain believed that Germany had been unfairly treated by the allies after its defeat in the 1st world war. His view was that Germany had sincere grievances that needed to be resolved; he also thought that by agreeing to some of the propositions being made by fascist powers Germany and Italy such as the Munich agreement than Europe could potentially avoid the outbreak of another world war. Meanwhile in the United States a combination of events such as the great depression and the losses suffered in world war one had pushed the American opinion and policy towards isolationism. Many Americans argued that the United States shouldn’t intervene in European conflicts or politics that did not concern them. Churchill however believed that not only did Nazi Germany and Facist Italy pose a threat but that the rights, traditions and fundamental beliefs of western civilization were in jeopardy and so he made it his mission to ready the British people for war and appeal to the US for aide against this threat. Now in his speech the defence of freedom and peace Churchill utilizes a number of literary devices the first of which is Allusion. Allusion is a figure of speech that makes reference to a place, person or event real or imaginary and can refer to anything which includes artist paintings, opera, mythical figures and bible passages. Churchill uses this to grab his audience’s attention and engage them into the subject while also getting his message across to them without having to go through tedious details. The first example of allusion is when he states â€Å"he (meaning Hitler) must blood his hounds and show them sport or else like Actaeon of old, be devoured by them†. Here he is referring to an ancient tale in Greek mythology Actaeon was a man who was punished by the goddess Artemis for boasting that he was a better hunter than she as a consequence she turned him into a stag, and his hounds turned on him and killed him. What Churchill is trying to get across to his audience is that if Hitler does not constantly lead his allies and soldiers to victory, they will eventually turn against him, taking his power for themselves. Allusion was further demonstrated when Churchill states to his audience that the American people wash their hands of the whole buissness.

Yasumasa Morimura and Marcel Duchamp Appropriations

Art speech: Artists who appropriate The post modern era is one in which things were twisted, changed and critiqued. Some people questioned the ways and ‘rules’ of society, rebelling against conformity and the usual ideas of what was ‘right’ or ‘allowed’. Artists were largely in this group. Marcel Duchamp and Yasumasa Morimura are examples of artists who appropriated other people, things and paintings in their work, to change their meanings, and either rebel against the norms of society, make a statement about issues affecting them and their culture, or to add humour to a once serious piece. Marcel Duchamp, born in France in 1887, to an artistic family, was an expressive artist who was able to think outside the square, and through his†¦show more content†¦Morimura was also a homosexual. He was very homosexual. This history led onto him investigating how Japan interacts with the outer world, by piecing together new identities in his artworks and photographs, combining his own culture with that of the global community. His gayness was also another factor which sculpted the issues in which come up in his pieces. Morimura appropriates the famous images from Van Gogh, Rembrandt, Manet and Frida Kahlo, and also the American Hollywood stars such as Marilyn Monroe, Vivian Leigh and Elizabeth Taylor, with his face inserted over theirs. In the image Marilyn Monroe, Morimura features in a digitalized photograph 3 times, where he appears in different poses of the pop icon Marilyn, from her famous movie the seven year itch. Each Morimura, as Marilyn Monroe, stands upon a pedestal, which accentuates her influential power, even with all her girly charm, which Morimura clearly defines. Morimura isn’t just playing dress ups. He is making a statement about the issues he feels he faces personally including sexuality, gender and race, and those affecting Japanese society such as race and the western impact upon Japanese culture. Morimura considers himself as being â€Å"a performer, in costume, in makeup, representing a character that is both well known, yet making a current social statement.† Morimura uses his characters to make the statement to societyShow MoreRelatedAppropriation in Art Essay1015 Words   |  5 Pagesissue of appropriation in art has become a heated debate on whether it is good or whether it is bad. Appropriation is fundamentally the act of taking something from somewhere else and placing it into a new context. In art, appropriation is seen as using (or taking) someone elses artwork, manipulating it and ultimately changing the whole meaning behind the work. It is seen as a significant issue as many people (including art critics, art historians and art enthusiasts) see appropriation as whilst
