Darwins Theory of Evolution by Natural Selection (Essay Sample) Content: DARWIN'S THEORY OF EVOLUTION BY NATURAL SELECTIONName: Crystal SmithCourse: BiologyInstructor:Date: 28th November 2014QuestionDarwin was not the first to consider evolution as a process but he did come up with the first effective explanation for how it happens. Describe Darwinà ¢Ã¢â€š ¬s theory of evolution by natural selection. Explain how this theory was a major advance over prior ideas as to how organisms changed over time. Give evidence in support of evolution and describe the driving forces for evolutionary change.SolutionDarwin's Theory of Evolution by Natural SelectionDarwin's Theory of Evolution is a relatively young type,. Charles Darwin brought something new to the old Theories called "natural selection." Natural selection acts to accumulate minor advantageous and preserve genetic changes. It believes that some species developed a functional advantage over others and its offspring would inherit that advantage and pass it on to their offspring. The disadvant aged members of the same family would die slowly, leaving only the advantaged members of the Family. This theory is the preservation of a functional advantage that enables a species to compete better in the wild. This theory of Evolution is a slow and gradual process. From Darwin books in 1859 he said; Natural selection acts only by taking advantage of slight successive variations (Darwin 1859).The following is the summary of Darwin's Theory of Evolution by Natural Selection; 1 Phenotypic variation among individuals exists and the variation is inherited. This means that there is genetic variation; hence there is variation in every population. 2 More individualà ¢Ã¢â€š ¬s species are produced in each generation that withstands the conditions prevailing. 3 When there is isolation in reproductive new species will form and suitable traits will be passed on to the young ones 4 Those species with heritable traits will better suit the environment and will survive. This means that species with suitable characteristics will survive and reproduceDarwin's theory of evolution by natural selection is the best supported theories in the history. There are much evidence from various scientific disciplines, which including paleontology, genetics, geology and developmental biology. Natural selection is well supported by the changes in various speciesThe following are reasons why Darwinà ¢Ã¢â€š ¬s theory was a major advance over other theories of evolution;There have been many theories explaining evolution. Two of the most well known of these are the Lamarckian theory, which was mostly believed before the Darwinian Theory, which is believed to have the highest probability of it being the case. In Lamarck's theory of evolution, it states that an organism was able to pass on required traits to their offspring. This has been shown in the evolution of giraffe's evolution to having longer neck and longer legs. As per Lamarck's theory, during a bad season when all the vegetation in lower areas and can be reached by the giraffe with the shorter neck and legs had gone, they necks where stretch, to reach for food on a higher level. They have longer necks and passed this trait of longer neck and legs to their offspring. This led to the longer necks of giraffe like the one seen today with its long neck and legs.Darwin's theory relied history that, at the start there was very many giraffes with different heights, due to the variations in species through the reproduction. Darwin stated the giraffes tried to compete and struggle to exist. During a dry season the nutrition available are low levels ,during these times the giraffes with longer necks and legs are likely to survive hence the giraffes with the shorter necks and legs would die, Cutting them from pass on their genes, resulting in a new generation of giraffes with longer necks and legs.Also Lamarck Theory would have believed that the changes in the horse traits were due to its environment. The horse strugg led to run faster and escape predators when out in the bush; hence they developed a stronger, body to with stand the need for high speed.Darwin's theory thinks from the perspective of changes in the genes and would differ with Lamarck Theory by, saying that the horses that survived were the ones, who could run faster. And are the horses with the longer legs, and so the genes of horses with longer lags would have been passed to the off springs.The following is the Comparison of Darwinà ¢Ã¢â€š ¬s theory and other evolution theories;It was Darwin's genius both to show how all this evidence favored the evolution of species from a common ancestor and to the generation we have at the moment. Lamarck and others theorist had promoted evolutionary theories, but they used speculation in order to explain changes in life. They claimed that the evolution of different species was guided by long-term trend. For example, Lamarck thought that life rise from simple single-celled to form complex ones . Many German biologists conceived of life evolving according to predetermined rules, in the same way an embryo develops in the womb. During the mid-1800s, Darwin and Alfred Russell Wallace independently conceived of a natural, even observable, way for life to change: a process Darwin called natural selection.

nbsp;nbsp;nbsp;nbsp;nbsp;Media Manipulation nbsp;nbsp;nbsp;nbsp;nbsp;There is a very subtle, yet powerful force at work on our world today. It is trying to control what woman and young girls do say and believe, especially about their own appearances. The media portrays unrealistic images that affect the way people, particularly woman, feel about themselves. And there is no way to avoid it. The media acts as a transmitter of potentially dangerous, socially desirable values and norms. Anyone can become a victim without even realizing it. Woman are told to believe distortions, inaccuracies, and bias on a daily basis. Somehow in that all the madness thinness has become synonymous with attractiveness.

They watch it all voluntarily, unable to recognize the damage being done. The images in and on TV shape the values of young people as well as adults. Sadly, these same images are part of a culture in which one out of every woman has an eating disorder, (Levinson 46) girls and younger woman increasingly have problems with low self esteem that eventually leads to dangerous behavior, (www.ed.gov. ERIC...) and where illusions are almost always shattered.

Sample Extraction Technique Is Necessary For Various Other...

Mel cepstral feature extraction technique is required in some or the other form in most of the latest speech and speaker recognition system. Here, first samples of speech are splitted into overlapping frames. Generally the length of frame is 25 ms and frame rate is 10 ms. Each and every frames are refined by pre-emphasis filter which amplifies higher frequencies. Next is to apply windowing so that Fourier spectrum for each windowing frame is achieved here Hamming window is used. To obtain vector of log energy, Mel spaced bank of filter is used which varies from 20 to 40 depending upon the requirement of particular application. The output of which is converted to give cepstral coefficients using DCT. Initially for computing the feature vector, 12 coefficients are obtained along with one energy make its 13 cepstral coefficient. The extended MFCC consist of triple differentiation. 1St order differentiation is known as Delta coefficient is denoted by _D which has 13 delta cepstral coefficients. 2Nd order differentiation is known as Acceleration coefficient is denoted by _A having 13 delta delta coefficients. 3Rd order differentiation is known as Third order (Triple delta) coefficient is denoted by _T which again has 13 triple delta coefficients. Its is said that standard MFCC is given by 39 feature vector and extended is given by 52 standard vector [1]. When training and testing is performed in noisy environment, there is severe mismatch which also effects the features.Show MoreRelatedContemporary Issues in Management Accounting211377 Words   |  846 Pagesregistered trade mark of Oxford University Press in the UK and in certain other countries Published in the United States by Oxford University Press Inc., New York ß Oxford University Press 2006 The moral rights of the author have been asserted Database right Oxford University Press (maker) First published 2006 All rights reserved.

Development Of Early Childhood Development - 3413 Words

Early childhood development is such an intriguing aspect to research because this is really a point in life where children act without reasoning and logic skills. The actions and thinking patterns for two to six year olds is not wrong, it is just illogical and children these ages cannot perform while thinking about a larger perspective other than themselves; which also makes this so fascinating. In my research and observations, I focused on how children during this developmental stage act and not so much about the cognition and processing a child does to make them behave in these certain ways.The theories and ideas are steadily researched, but less rarely show examples ,that are representative of the population of children in early childhood that support the theories. Instead of exploring phenomena more deeply to reiterate and validate these theories of brain functioning and processing, such as Piaget’s preoperational thought theory, I will instead explore a few phenomena and theories to demonstrate what they are and how they apply to early childhood development using applicable personal experience including observations done myself and the observations of previously conducted research and face-to-face interviews to support these ideas. Throughout early childhood development, children experience many things that they do not really know how to interpret and rationalize. Isn’t this just the most adorable stage of development?

How Energy Crisis Is A Crisis Of Human Development Essay

1 Introduction: Energy production of any country is the measure of its economy. No country can achieve high economic growth without producing sufficient energy. Production of energy crisis is a Greek word which means ‘decisive moment’. Crisis is declared when something has gone to a level where an action must be taken to avoid complete disaster ‘Energy crisis, takes place due to several reasons some of which are: increasing price of oil,power wastage ,less dams,incompitancy of exploration sector, miss allocation of resourcesflects industrial output,transportation,agricultural output,etc.Electricity breakdown in Pakistan is alarming.

The first stepping stone in Pip’s coming of age is finding a place to belong. A quote that shows the fact that Pip did not know where his place was is when he says â€Å"l am ashamed to say it,† I returned, â€Å"and yet it’s no worse to say it than to think it. You call me a lucky fellow. We will write a custom essay sample on GE Bildungsroman or any similar topic only for you Order Now Of course, I am. I was a blacksmith’s boy but yesterday; I am-?what shall I say I am-?to-day? † (Dickens 196). Before Pip knows where he belongs he lives the dreaded life of a blacksmith. He knows what he wants, but he must grow to achieve his goals. An instance in which Pip shows that he has found where he belongs is when he says â€Å"As passed the church, felt†¦ Sublime compassion for the poor creatures who were destined to go there, Sunday after Sunday, all their lives through, and to lie obscurely at last among the low green mounds† (Dickens 139). This quote shows how much Pip despised his old small town life. At this point in the story, he seems to know what he wants, and has no intention Of living and dying in the same place. Another quote which shows that Pip comes of age by finding where he belongs is when he tells Estella ‘You have been in every prospect I have ever seen since – on the river, on the sails of the hips, on the marshes, in the clouds, in the light, in the darkness, in the wind, in the woods, in the sea, in the streets† (345). Pip, completely infatuated with Estella, has found his place physically in London, but mentally with Estella. No matter what he cannot stop loving Estella and is convinced that she is the one for him. Pip had to first find where he was destined to be to come of age. Once Pip finds where he belongs, he also figures out who he can depend on, which is another milestone in Pip’s coming of age. The first lifelong companion that Pip figures out he can depend on is Joe when he tells him â€Å"l sis it was only me that got put out, Pip; I wish there wasn’t no Tickler for you, old chap; I wish I could take it all on myself†¦ † (50). Through Joe?s comforting and caring words, Pip knows he can depend on him as not only a best friend but a father. Despite the abuse of Mrs.. Joe, he wants to do right by women, and more than anything else, he wants to protect Pip, in which Pip comes to realize and respect about him. Another person Pip learns he can depend on is Biddy, from which he says â€Å"She was not beautiful – she was common, and could not be like Estella ; but she was pleasant and wholesome ND sweet-tempered† (131). Although he will never love her in the way he loves Estella, Pip will always trust and depend on Biddy because of her patient behavior and her role in helping Pip with his education. Biddy is a constant in Pip’s life, a stable aspect in which he knows he can always depend on. Another person who Pip depends on throughout his coming of age is Miss Having when she says â€Å"You made your own snares. Never made them† (361 Pip can depend on Miss Having to be honest with him. Without the honesty from Miss Having, it would be harder for Pip to grow up. Once Pip learned whom he could depend on, those individuals helped him grow up and come of age. After learning who was most important in his life, another stepping stone in Pip’s coming of age was learning what is most important in life. A quote that shows the fact that Pip did not know what was actually important is when he says â€Å"l was to leave the village at five in the morning†¦ And I told Joe that was to walk all alone. I am afraid†¦ That this purpose originated in my sense of the contrast there would be between me and Joe, if we went to coach together (156). Pip was so concerned about his social status that he Was ashamed to be seen with Joe. Before Pip learns what is most important in life, he thinks it is his social status. A quote showing Pip’s transition into realizing the important aspects of life is when he thinks, â€Å"It was fine summer weather again, and, as I walked sunshine should be softened as they thought of me (260). In this thought, Pip is reminiscing on his childhood and with this develops a hope to be remembered after he is gone. Pip comes to realize in the back of his mind that he wants to be remembered or his personality, and not so much his status. Another quote in which Pip finally realizes what is most important is when he states â€Å"l washed the weather and the journey from my face and hands, and went out to the memorable old house that it would have been so much the better for me never to have entered, never to have seen† (270). Pip comes to the conclusion that he would’ve been better off if he had never entered the sati house or ever became infatuated with the idea of being wealthy. Pip opens his eyes to realize that the road to wealth and status never even mattered, and this is here he comes of age. How to cite GE Bildungsroman, Papers

Controlling Communicable Disease

Questions: 1.Description of the communicable disease (causes, symptoms, mode of transmission, complications, treatment) and the demographic of interest (mortality, morbidity, incidence, and prevalence). 2.Describe the determinants of health and explain how those factors contribute to the development of this disease. 3.Discuss the epidemiologic triangle as it relates to the communicable disease you have selected. Include the host factors, agent factors (presence or absence), and environmental factors. (The textbook describes each element of the epidemiologic triangle). 4.Explain the role of the community health nurse (case finding, reporting, data collecting, data analysis, and follow-up). 5.Identify at least one national agency or organization that addresses the communicable disease chosen and describe how the organization(s) contributes to resolving or reducing the impact of disease. Answer: 1. Introduction Healthcare service providers are highly concerned about the communicable infectious diseases. The unhealthy and indiscipline life style of modern human beings lead to several different kind of diseases, most of which are infectious and communicable through one person to another person. There are several communication diseases such as chicken pox, tuberculosis, hepatitis B, HIV etc. Among them HIV is the most critical diseases, which become the main headache of the health care service provides, because HIV is increasingly spreading in the society. HIV is mainly spreading by the means of risky sexual behaviour as well as unprotected sex; due to unprotected sex the HIV virus enter to the non-HIV person from the HIV person. This is a fatal disease, which destroy the immune system of the human beings. There are several determinants, which accelerate the growth of the diseases in our society, such social and cultural background, economic factor, which influences the peoples to perform this type of unruly, risky and unprotected sex and that are main cause of HIV. The community nurses play vital role in the treatment of the HIV, several organizations also put great emphasis in preventing as well as treatment of the HIV patients Description of the disease HIV causes one of the most critical diseases called AIDS or acquired immunodeficiency syndrome.HIV is the abbreviation of human immunodeficiency virus. If once in life you have HIV, it will be with you for the rest of your life (Noah, N. 2006). It is a typical blood borne disease, which transmits during sexual intercourse, it also can occur during breast-feeding and during the birth process.HIV disease can occur if one has the infection with HIV 2 OR HIV 1They are both retrovirus and they belong to the Retroviridae family. Scientists believe that a kind of chimpanzee in the region of West Africa is the source of HIV in human. That is why according to the research it can be, said that HIV may have come from apes to human beings. There are no specific physical findings to HIV. Manifestations may include the following points. Generalized lymphadenopathy may be, referred as a presenting symptom and it is very common too. Flulike illness, malaise, generalized rash are the acute manifestations HIV virus destroys the cells of the human body. It destroys the immunities power of the body. 2. Description of the determinants Many factors can affect the health of communities and individuals. The factors such as genetics, locality, the state environment, relationships with family and friend and income and education levels all have substantial impact on health. The determinants of health are: The economic and social environment, The physical environment, The behaviour and characteristic of the individuals The health disparities in sexually transmitted diseases such as HIV/Aids are, linked to complex bend economic and social determinates. HIV can be, developed under various conditions, all around world with the consequent variations in the rate of transmission and mode of transmission. In the developed countries men who have sex with the men after that needle sharing the drug user is increasingly concentrated in marginalized and poor sectors of population. The structural and social intervention that focuses on the education, job security, housing, health services, social and income exclusion are addressed to the root cause of the HIV vulnerability. The physical environment can also leads to development of HIV is closely tied to the employment conditions. The people who have low level income can put them to higher risk of exposure to the contaminants that are harmful to the health. 3. Discuss epidemiologic triangle According to the epidemiologic triangle of Aids distinguishes the determinants into three levels, which includes individual, social and structural. The individual aspect can be, described based on the biologic, demographic and behavioural risk factor, which can influence the risk of transmission and progression of AIDS in the society. The social level in the epidemiologic process includes the essential pathways by which the society and system of network structures link individuals to society (Bennett, L., Searl, S. 1982). The system of network is at the centre of understanding the perceptive of diffusion and discrepancy division of HIV/AIDS in the residents of the subgroups. The structural factor mainly related to the social and economic factor of the population along with the established laws and policies in order to avoid issues related to this communicable disease. The Cultural context, social networks, neighbourhood effects and social capital are the important social level facto rs in HIV/AIDS epidemiology. There are five main categories of structural-level factors; they are legal structures, the policy environment, structural violence and discrimination, war and militarization and demographic change. Role of community nurse Collection of the data, case finding and analysis of the data related to the cause and prevention of HIV disease is very crucial for the nurses. There are certain principles followed in nursing for the treatment of HIV. The nurses should have the ability to identify the desired stage of illness of the disease. Proper data should be, collected related to the cause of the diseases. Complete analysis is very crucial and it should be, executed with the help of the doctors as well as the professionals of the health care centres. Appropriate methods should be, adopted by the nurses related to the finding of the cause of the disease. Nurses should execute their proper skills for the treatment of the patients. There should be proper food choice provided to the patients from the nurses as well as there should be proper washing of the hands of patients as it is a communicable disease. There should be proper preventive measures guided from the nurses to the patients relating to the spraying of this disease. Analysis of the data helps in proper identification of the disease and helps to provide proper solution to the disease (Hawker, J. 2005). 4. Organization that address the communicable disease CDC helps in providing perfect resolution for the prevention of the HIV disease. The organization implements advanced technical methods in the prevention of this disease. First of all the organization identifies the occurring of this disease. Then it implements various methods of effective treatment and provides proper guidance to the patients related to the food choice and proper washing of the hands. These methods help in not spraying of the disease to the other people. It provides resolution to the patients related to HIV meditations, prevention programs and provides guidance related to high risk of the disease. Screening as well as treatment of the disease HIV plays a vital role in curing of this particular disease. Conclusion HIV, Human Immunodeficiency Virus is the virus that affects a human being to suffer from AIDS, Acquired Immune Deficiency Syndrome. In this disease the symptom worsens as the infection increases. HIV affecting the person in the fluids of the body causing the disease to spread from one person to another as the person comes in contract through passing the blood or through sexual contact. The social determinant of the disease is huge as this disease is not accepted in the society. There are activities conducted by NGOs providing knowledge about the disease and ways the patients should be, treated. Even the discrimination between different classes or sections of society effects the treatment of the disease. This disease is infectious bringing the triangle or the three corners as; Agent, Host and Environment. The Epidemiologic Triangle should be broken in order to stop the continuation of the disease. The roles of the community nurses are to spread awareness of the disease in the family members, friends and the community. References Noah, N. (2006). Controlling communicable disease.
