Mate Selection Theories essays

Mate Selection Theories essays To describe men and women's differential preferences in mate selection, I am going to use the following theories: 1) sexual selection theory, 2) parental investment theory, and 3) social learning theory, and 4) sexual strategies theory. All of these theories have been used to explain why men and women have differential preferences in mate selections. In the evolutionary approach, biological fitness is defined as reproductive success. Therefore, understanding particular behavioral sex differences is of great interest to evolutionists. Reproduction is central to the evolutionary process and no domain is closer to reproduction than sexuality. Darwin (58) adopted phrase "survival of the fittest" to summarize the process of natural selection, but this choice was unfortunate. Survival is certainly critical. Many adaptations of organisms exist because they successfully overcame the forces that impeded survival, such examples are parasites, diseases, food shortages, predators, and Darwin (67) also fashioned the use of term what he believed to be a second evolutionary process, which he called sexual selection. According to sexual selection theory, characteristics that give organisms an advantage in the competition for mates can also evolve. Sexual selection can operate through two processes. The first is intrasexual or same-sex competition. If members of one sex compete with one another, and the victors of these competitions gain preferential sexual access to mates, then these useful qualities lead to success in same-sex competitions will be selected and can evolve over time. These might include athletic ability, social skills to enlist allies, or even a sense of humor that deters a rival. The key point is that whatever qualities lead to success in same-sex competitions can evolve because of the reproductive advantage that accrues to the victor The second component...

Development of Research Questions - Essay Example fact Open Doors report provided by the Institute of International Education (IIE), recorded an increase of 3% to 690,923 of student enrolment during the 2009/10 academic year. So it is crucial how the courses are introduced so that the international students can follow the curriculum given the two most common challenges they have to face; that of having a grasp over English and the associated stress due to culture shift. And when the students are pursuing a highly technical course like accounting, the learning difficulty multiplies. For it is typically assumed that all students are familiar with the basic concepts of accounting, its core definitions, and main transactions. But the general perception of accounting courses among students is that they are difficult to study, and students are expected to work hard to succeed in these courses. One of the big reasons is the difficulty with English comprehension. For this special group of students, which usually enter on F-1 visa, English i s a second language and it is imperative that they master it in order to understand and grasp complex accounting matters. Typically, these students need to make extra effort to connect what they just learned and what it should mean. As a result, complex accounting material becomes even more complicated for this particular group to do well and succeed in the accounting courses. The anticipated research study will be conducted on various issues and opportunities that this unique group of students experience while taking accounting courses namely coping with English and its impact on academic performance, the consequent stress of being in a new culture and the intervention services that could be extended to them. Therefore the proposed dissertation topic is as follows: â€Å"International students in accounting course in the U.S: Challenges & opportunities†. The impact of foreign students on the educational industry in America could not be ignored both in terms of the financial aspects

History of human evolution Research Paper Example | Topics and Well Written Essays - 750 words

History of human evolution - Research Paper Example There are a lot of progressions and interactions going on in the universe and for everything to survive, these progressions are important. The same is for humans. For humans to exist, they must undergo some process which is commonly known as evolution. Humans have evolved through evolution. Aristotle was the first biologist that identified humans as rational animals that have a distinctive ability to reason and make judgments, due to which they are different from other animals.Cela-Conde and Ayala assert in their book that all organisms tend to have common ancestors (1). According to them, â€Å"Biological evolution is a process of descent with modification† (1). If we go into the depth of this statement, we come to know how we evolve from what we were and what we are today. hominidae is the term used to describe the lineage spreading from the final common ancestor of man and apes. Hominid is the term given to a species in the family. According to paleoanthropology, the histor y of human evolution shows that the common ancestor to both man and apes existed â€Å"about 5.5 million years ago†, states Professor Grover Krantz. Ramapithecus was one of the most ancient hominids whose fossils were found at that time. Paleoanthropologists believe that the bipedal adaptation of the ancient hominids evolved when that ancient hominid decided to live at the border of forests under the trees instead of inside the forests and in the trees. This was about four million years back, but how we look like today is much different because our modern facial features evolved much later than that. The bipedal adaptation then evolved into upright walk that is how we walk today. Paul Rincon, a science reporter in BBC News, reports that scientists have found in Western Europe, and specifically in Spain, the most ancient remains of human. He reports, â€Å"A jawbone and teeth discovered at the famous Atapuerca site in northern Spain have been dated between 1.1 and 1.2 million years old.† Borgus, the city of Spain, is well known for having many antique limestone caves that contain fossils of early hominids and other tools that show the occupations of early humans. As far as United States is concerned, most Americans believe that humans did not evolve over a period of time. However, there is a designer God who designed the mechanism of humans and created them magically. There are two parts of human biological evolution: Anagenesis and Cladogenesis. Anagenesis Also called phyletic evolution, ancestry of organisms changes generation after generation. Kesner and Olton describe anagenesis as progress of the humankind in evolutionary context (15). Continuous natural selection results in the modification of forms and organs so that they perfectly adapt to the new environments and habitats. Cladogenesis Another name for it is lineage splitting which means that new species come into existence with the passage of time which results in diversity. While modifi cation in a phylogenetic lineage is occurring, branching of forms also occurs at the same time which causes them to expand on the face of the earth. Natural Selection Considered as one of the most fundamental processes that results in evolution, natural selection was a concept put forth by Charles Darwin in 1859 in his book On the Origin of Species. According to this concept, organisms (or traits) that are best suited to the environment are selected by nature to prevail due to which they are able to pass on their genetics on to the following generations. On the other hand, organisms (or traits) that are not best adapted in the environment tend to vanish away. Human evolution has also been influenced by this concept of natural selection. According to Darwin, as he states in the revised version of his book, another name for natural selection is survival of the fittest (Darwin 8). Nature brings variations in the organic beings so that they are best suited t

Oscar Niemeyer Design Philosophy

Oscar Niemeyer Design Philosophy Being born as the son of Brazils Federal Prime Minister, Oscar Niemeyer was living in a Portuguese colonial style house with beautiful tropical setting: a wide carriageway, neatly lined with tropical trees, that curves along the broad seawall looking out to the dome of Pao de Acuacar guarding the bays mouth; lawn designed as formal gardens Niemeyer obsessed over the landscape of his motherland Brazil. No matter how different his house designs vary through time, the element of landscape is always strong and evident. This essay focused on Niemeyers house designs. Being an icon of modern architecture, Niemeyer pushed the limit of reinforced concrete and revealed the expressive charm of this artificial material. The contemporary architecture was monotony. Niemeyer wanted to challenge it. Niemeyer is well-known mainly because of his design for some of the most dominant governmental buildings in Brasilia, Brazil. As one of the early pioneers of modern architecture, Niemeyer opened up a unique approach to contemporary architecture using bold free-form curves in design. Some of his house projects were equally powerful in terms of his dramatic application of free-form. But other projects indicate more thoughts in Brazils colonial background and his own formal exploration throughout his career. Niemeyer did a series of house projects with a huge time span from 1936 until now. Among the dozens of house projects, there are extremely luxury houses he designed for wealthiest Brazilians, there area also some house he designed for middle-class friends and family. Niemeyer also designed four houses for himself. One house, Casa das Canoas, was his most published and well-known work. Four houses designed in year 1942, 1949, 1953 and 1960 had varies characters and different concepts. As Niemeyers other house design sometimes have to fulfill his clients requirements, his own house designs seems to be trademarks of his career, evolving through different phases. The first house he designed for himself is located on a sloping site in Lagoa, Rio de Janeiro. Graduated from National Fine Arts School in 1934, Niemeyer was deeply influenced by Le Corbusiers visit to Brazil in 1929. He joined Costas office in 1935, and from 1936-1942, he was working mainly on the Ministry of Education and health Building, on which, Le Corbusier was invited as project consultant. During this period, influence from the modern master was obvious and they got clearly reflected in Niemeyers first house. The three story house was zoned with clear rationality. The main living room and bedrooms are clearly separated from the service area. A set of scissors ramp is just identical as the one appeared in Le Corbusiers Villa Savoye in terms of its function as the only connection between different floors. The rectilinear upper floors sit on columns on the ground floor, with curvilinear walls direct the flow from entrance to garage and later towards the ramp. Horizontal openings on the facade give a clear indication of free elevation. However, the house is not a simple duplication of Le Corbusiers work. Niemeyer started to explore forms and material in the context of Rio, which is a humid tropical Brazilian city. A single direction slanted rooftop deals with the massive rain water during the monsoon season. A veranda on the second floor fully opens to the lake view. The material he used for the elevation is also unique. Different from his later larger public buildings which mainly deals with reinforced concrete, brick and wood was applied as elevation infill. On the top floor, the wall is composed with wood trims originally painted in blue. Wooden louvered panels were added to cover the veranda. Wood was also widely used as the material for interior finishes as well. The symbol of house as a machine, ramp, in Villa Savoye was no longer represented in cold metal frames and concrete finish. It was covered in wooden panels on the side and a wooden frame. On the ground floor, bushes were planted from the irregular sit e boundary towards the hose edge, defined by a hard pavement following the outline of the elevated second floor. In this project, although marks from Le Corbusier are clear through the use of free plan and clear zoning in a house project. Niemeyers awareness of context and site was already obvious. This prototype of dwelling on top of the landscape evolved and became one of the most frequently used prototypes in his later house designs. In 1949, Niemeyer designed another house in Mendes, RJ. The house was built and later demolished. The house has a very dominant feature which was the slanting screens shelter the porches for living room and bedrooms. Different from his first house for himself, this house was located on a flat piece of land with the trees surrounding it and a stream runs in front of it. The setting is purely natural, not urban. The difference in the context led to a very different design solution. The single floor house is organized in a rectilinear order with all the rooms facing the screen and indoor garden in between. Here, a hint can be found between his modernist approach and traditional colonial architecture. The old colonial porch was transformed into a screened indoor garden, blending the artificial indoor and purer nature outside. This became a prototype which the landscape and the artificial indoor environment was articulated on the same level through a buffer garden. In 1953, Niemeyer designed his most published house, Casa das Canoas. The design was open to the world and shocked the audience with its curvilinear roof. Just before the CIAM meet for the first time in Brazil in 1954, the house was finished. Niemeyer faced some of the most dominant figure in modern architecture with their critics on the house. Walter Gropius and Mies van de Rohe were both attracted to its beauty but pointed out the uniqueness of its geometry became he limit that it can not be multipliable. Faithful to his ideology of mixed ancestry and Antropofagist hybridization, Niemeyer proceeded to infect the classical pavilion with the organic, spontaneous architecture of the morros, mixing Western achievements in the field of domestic architecture with tropical exuberance and lessons from Brazils colonial past and popular present. Case das Canoas is one example of Niemeyers treatment of continuity between the interior and exterior. Curve and landscape became the media that he utilized to achieve it. With the irregular curvilinear roof lines, the nature surrounding the house became closer and farther, varies according to the geometry. A large piece of rock placed right at the edge of the glass wall, penetrating the transparent faà §ade and made it even less dominant. The warm wood finish of the interior partition wall conter-balance the rigidity brought by the steel frame of the glass faà §ade. The white ceiling and black floor becomes the frame of the this transition between na ture and artificial. The exploration of the form continued and became more vigorous when he designed an unbuilt house in Tel Aviv, Edmond de Rothschild House. This time with the desert becomes the setting, the free-form geometry was reverted from edge of the house to its inside. A free-form garden is enclosed by a rectilinear volume. Just at the time when Niemeyers free-form house design became a signature image. In 1960, he designed his house in Brasilia in a totally traditional colonial style. It creates a very strong contrast between the ideology of Brazils independence and its colonial historic roots. On the one hand, with the huge governmental projects, Niemeyer was creating the most powerful formal language, trying to declare to the world that Brasilia represents Brazils new future. On the other hand, he showed his respect very thoroughly to the colonial style, honest and modest. The houses feature a covered porch with red-tiled gable roof, whitewhased walls and regularly spaced windows. More houses will be discussed following the category of the four houses Niemeyer designed for himself. These houses includes: Edmundo Cavanelas House Allvorada Palace Carmen Baldo House Burton Tremaine House Weekend house for Juscelino Kubitschek Cavalcanti house Overlaid with the complexities of Brazils history and stratified society, these scenes evoke contradictions that Niemeyers designs have always balanced: natural shapes created by artificial technology, structural logic and ecstatic emotions, simple forms and complex purposes. Niemeyers house design showed his critical thinking and evolving career, just as strong as his public buildings. His public building may be restricted to their formal strength as a responsibility to speak for the nation. However, in his house design, there are clear trademarks of his weighing of traditional vernacular concept and modern formal exploration. Curves in Niemeyers house projects are more utilized as a mean to explore the relationship between nature and artificial, building and landscape, indoor and outdoor etc.

Environment Factors of Nascar Essay

Q1: What micro environmental factors affected the introduction and re-launch of the Toyota Prius? How well has Toyota dealt with these factors? Firstly, the company has spent a lot of money on the re-launch of the new and improved Prius model which is over 40 million dollars. On the same note it was also able to generate a profit represented by a 120% rise in the sales after some time of the re-launch. Starting off with the main objectives of the company to provide a new and technology product to the target market it was able to cover its operating and marketing costs and also make build a profitable customer relationship. Secondly, the agents helped promote the new brand hybrid. Since the company did not want to take any chance for interpretation of the features of Prius, they did not offer online purchase facility to customers. Thus, Toyota hired agents and provided professional training to them to provide maximum customer satisfaction. Thirdly, the company’s main target was those customer who were ‘techies’ and were ready to buy the product at its launch. The company made sure that their focused customers were well informed before the products launch i. e. 2 years before. Then, the company’s marketing strategies also included taglines with emotions which were very effective in its promotion. In summer 2004, the gasoline prices rose so the demand for Prius increases and so did the waiting lists. Toyota tried its best to cover the entire demand but still left some customers unsatisfied. Later on, it overcame this problem by a 33% and then a 100% rise in the monthly production. But the extensive and large scale advertising campaign and strong, overall marketing strategies helped Toyota to gain the competitive edge over them as well as the rest of the smaller rivals. Then, the incentive provided by the government of tax deduction also helped but the increase in the speed limit was a hindrance for Toyota which was also covered by the heavy marketing strategies. Q2: outline the major macro-environment factors demographic, economic, natural, technological, political and cultural that affected the introduction and re-launch of the Toyota Prius. How well has Toyota dealt with each of these factors? The main customer focus of the company was those people who were youngster i. e. belonging to generation Y. so the main focus of the entire promotional activities were the ‘techies’ due to which a major portion of their profits was contributed by them. With respect to the economic factors, the case shows that the customer had enough income to spend on this luxury. This is shown by the fact that the company was able to sell 1800 cars in immediately and also had to raise the monthly production level by 33% and then even by 100% to meet the demand. Toyota is an â€Å"environmentally concerned† company since it had greater fuel efficiency and lower emissions. It also took advantage from the environmental appeal by spending out green seed cars shaped like Toyota’s logo to prospective buyers on Earth Days. The technological factor is explained by the many factors including adding cruise control by some wiring, dashboard display screen, playing video games, installing sniffer, 7-inch energy monitor, a CD player holding 6 discuses at a time and many more. Since the customers favored technological products and had enough knowledge Toyota was able to maintain customer loyalty. Politically, the company received support from the government in the form of tax deductions which helped efficient production but on the same note the speed limit factor acted as a hindrance but was covered by extensive marketing campaigns.

Essay on The Changing Concept of Hero - 988 Words

When the hero was first struggling to be defined, there were many different observations and opinions readily available to be thrown into the melting pot of the definition. Because there was no television, the heroes in the beginnings of British Literature were spoken of and read about then passed down through generations. Reading these stories in this day and age is interesting to look at because we can trace the difference in the heroes throughout Beowlf, Sir Gawain and the Green Knight and The Faerie Queene and therefore literally throughout time. The differences that can be seen are the characters armor, the enemies that are being faced, and the values of each of them. Beowulf has no known author but it is thought to be written†¦show more content†¦He fights for and works hard to bring together the Danes and the Geats. Beowulf put his life on the line for his people time and again and proved himself each time. His death in the end brought his people together to mourn him as he would have wanted. Beowulf is a hero because of his unfailing faith, his people’s belief in him and his reputation as the greatest warrior in the world. The author of Sir Gawain and the Green Knight is also unknown but the date of publication is between 1375 and 1400. This is after the Norman Conquest, the Catholic church was the church of the country and the oral representations of stories like this were now being written. Gawain has more humanistic tendencies than Beowulf. He is tempted and can not completely refute that temptation. His humanistic tendencies make him a different hero than Beowulf altogether because Beowulf was a hero who could not seem to fail. Sir Gawain, when put under stress is not able to make a decision about what is the right thing to do. Bringing Sir Gawain down to the reader’s level is a new way to view the hero in that time. Sir Gawain’s armor is elaborately laid out and described unlike any of the other heroes being discussed. According to Professor Bruce McGee, the description of his armor seems to be thought of as a representation of his people’s convictions and standards. The penta ngle in the middle of his shield is eternal and incorruptible as a whole.
