Human Population Growth Essay

No matter what organism you are talking about, all living things possess the ability to reproduce. This comes in two forms. The first form of population growth is Exponential Population Growth. The second is Logistic Population Growth. Exponential population growth refers to when a population is not subject to any limiting factors, it will grow and expand exponentially even past the capacity of the environment to sustain. Rabbits are a good example of this form of population growth, â€Å"Thus, the exponential growth model explains how a few dozen rabbits can multiply into millions and overrun a continent. † (Simon, Reece, & Dickey, 2010) Logistic population growth refers to when a population reaches the capacity of the environment to sustain, the population growth declines. Fur seals of St. Paul Island are a good example of this, â€Å"After hunting was controlled, the population increased rapidly until about 1935, when it began to level off and started fluctuating around a population size of about 10,000 bull seals—the carrying capacity for St. Paul Island. † (Simon, Reece, & Dickey, 2010) Humans tend to exhibit exponential forms of population growth. We rapidly reproduce and expand, exceeding the carrying capacity of the environment. This leads to us spreading to other areas and exceeding the carrying capacity there as well.

Kantian Ethics concerning human Cloning Essay

Cloning is a procedure conceived to notion in the late 1960s, but it is only recently that it was fully understood and that scientists have started to figure out how to successfully copy the genetic composition of one organism to another. Since science already knows how to do this, the only problems and obstacles that remains is efficiency and the success ratio of each operation. The cloning process consists of taking the nucleus of an organism, and placing it, along with the DNA that contains all the genetic material, in place of the nucleus of the host egg. The egg then forms an embryo and matures into the same exact â€Å"copy†, at least genetically, as the original organism. Already done on mammals, cloning is something that can be extended to utilize humans as subjects. In the future it will be wholly possible to create human clones to serve whatever purpose they were conceived for. However, presently there are numerous ethical issues surrounding cloning and there are pro blems about the implications of the use of cloning for the purpose of medicine. This issue plagues us so much that the constant objections of bioethicists and political and religious leaders have caused the US Government to propose a ban on all research concerning human cloning until a conclusion is reached on the moral and ethical aspects of the process. (Macer, 2) In this paper, I will discuss how Kantian views and ethics help us understand whether it is morally ethical to clone for the purpose of bettering our lives. Two points have to be distinguished. How exactly will human cloning aid medicine and society, and the implications of human worth and dignity when applied to clones. Kantian ethics were proposed by Immanuel Kant in his critical writing of the â€Å"Groundwork of the Metaphysic of Morals†. Kant argued that â€Å"non-rational things have only a relative value as means and are consequently called things. Rational beings, on the other hand, are called persons because their nature already marks them out as ends in themselves†¦ for unless this is so, nothing at all of absolute value would be found anywhere†. (Britannica, 473) All persons are able to adjust their behavior to what they reason to be moral behavior, but in using this capacity that all humans possess, they must act upon a categorical imperative to treat all similarly situated  people equally. They must uphold to their moral maxims and make their actions universal law, extending it equally to all persons. Kant reformulates this idea and states that we should â€Å"act in such a way that you always treat humanity, whether in your own person or in the person of any other, never simply as a means, but always at the same times as an end†. (Britannica, 472) This means that we should never use people as only a means, and that because all persons have intrinsic human worth they should all be considered as ends in themselves. Kant’s vision involves only persons or rational agents. If no ‘person’ or rationality is present then it can be argued that the agent is simply a thing. Something that cannot rationalize and is not conscious of its existence cannot be argued as having human worth. So it is wholly possible, through some applications of science, to create â€Å"headless† clones that are not fully developed in the forebrain and who therefore cannot rationalize or exist consciously. (Friedman, 3) If able to be kept alive after their conception in order to mature, these clones can be used for harvesting of their organs for various medical purposes. Kant would not object to these kinds of clones because his concept of rationality is respected in accordance to the categorical imperative. If only rational agents are to be used as an end, and if no rationality exists, then whatever is left can be used only as a means to further some goal with no ethical wrongdoing involved. Developing a â€Å"headless† clone involves a process that prevents rationality and consciousness from ever being formed. This can be paralleled to other procedures that involve the same block of formation of rationality, particularly any form of birth control. Not allowing the development of â€Å"headless† clones because it is immoral makes any sort of birth control thus immoral too, because they also involve the preventing of the development of consciousness and rational thought. (Friedman, 4) If this imperative were to be upheld to a moral maxim, then we would need to be consistent in our actions and ban birth control just as human cloning is banned now. However, if human clones are developed as persons (with a whole brain and  fully functioning in every aspect) then our perspectives need to be changed to take a more moral view. Is it possible to morally clone a human to become an end in themselves? Suppose the case of a childless family where the mother is unable to conceive for whatever reasons. Somatic cell cloning can provide the family with a way to obtain a child through surrogate birth. (Friedman, 2) Even though copying the genetic composition of one parent and making the child a copy of them is somewhat strange, it is understandable from the parents’ point of view. If they are unable to naturally conceive, they should still be given some sort of chance to have a child. Cloning gives the parents this chance to have a child and have a somewhat normal family as an outcome. In this case the clone is treated as an end. He will grow up to be healthy and hopefully be regarded the same as a naturally conceived child. When he grows up, the clone will not denounce his existence. If asked the question of whether he would have rather not been born, the child would most likely thank cloning for his conception. The similar can be said for a clone that is used as a means for something but eventually becoming an end in themselves. Suppose the case of a family where a serious disease plagues an existing child and that only a specific blood type or a certain type of bone marrow will save him. If no donors are available, the child’s only ticket to survival might be a clone. Using the same genetic composition, his twin can be cloned in order to save his life. If this cloned twin is afterwards discarded, because he no longer serves a purpose or if he dies during the transfusion, this would in turn be highly unethical and immoral. However, if the parents exercise the human right of the clone as a person to exist, they are acting in accordance with the categorical imperative as stated above. They are extending the moral maxim to a universal law, and are treating the clone as a person, justly. The clone then becomes not simply a means to save a child’s life but an end in themselves also . The clone’s rationality and consciousness is not jeopardized. And in the same way as above, the clone would be thankful for having saved someone with his existence and would not regret his life. The immediately foreseeable problems with cloning for the purpose of childbirth might be seen when parents want to dictate the genetic makeup of  their child. They might not only want to eradicate genes that make a person susceptible to certain diseases, but they also might want to eliminate other unfavorable genes. Genes that control a person’s susceptibility to violence or other emotional factors, or genes that control a person’s appearance, such as height, hair and eye color and physical condition. In this way, parents might be able to mold genetically superior children to their liking. This would is most probable to eliminate uniqueness and individuality. There would be no randomness or pureness of nature in humans. Everything would be similar because certain specific qualities would be more favorable and popular. Also gene superiority would label clones as of higher value and might cause discrimination based solely on one’s genetic makeup. Only through tot al anonymity would this be preventable, and this condition is impossible. This problem can be directly related to the categorical imperative so crucial to Kant and Kantian ethics. Because morality must extended to be universal, it is imperative that both the superior clones and regularly genetically endowed humans are treated with similar regard. This however would seem to not be the case; the clones would always be favored in any situation. Therefore, this treatment would be immoral, as it would be immoral to clone human persons for such purposes, which are based only on vanity of people and discrimination of less favored genes. Many ethical issues and moral aspects of human cloning must be observed to get a larger picture of its implications. Kantianism gives us a way of differentiating in which situations will cloning be ethical or, the opposite, immoral. However, Kantian ethics is pretty specific in its situations and it can’t give a much more general and broad understanding of the ethics of cloning. It doesn’t tell us what to do, it only tells us whether something is moral or not. Kantianism is not a guide of morals but it is a very good understanding of them.

Feminist Literature Is Greatly Represented English Literature Essay

Feminist literature is greatly represented in the two narratives, Sweat, by Zora Neale Hurston and Strong Horse Tea by Alice Walker. Females in society have it much harder than work forces, in world ; females still make 70 cents of a dollar that work forces make. It is a battle for adult females everyday in the universe. Feminist literature, as the name shows, is based on the values of feminism, and refers to any literary work that centers on the battle of a adult female for equal chance, and to be acknowledged as a human being, before being shed into a gender stereotype. Not all these plants follow a consecutive attack towards this end of para. It is merely through such media that adult females alleged a alteration was possible in the manner they were professed in society. Alice Walker wrote many narratives. She was born on February 9, 1944, in Eatonton, Georgia. She was the youngest kid of eight siblings. A scholarship pupil, Walker went to Atlanta ‘s Spelman College for two old ages and so reassigning to Sarah Lawrence College in New York. After graduating in 1965, she began her calling as a poet, printing her first book in 1968. She early exhibited an consciousness of her forebears in the Harlem Renaissance, redacting a aggregation of the Hagiographas of Zora Neale Hurston. Zora Neale Hurston was born in Notasulga, Alabama ; no existent day of the month of birth even exists. She excessively is a kid of eight siblings. Hurston published her first narrative while a pupil at Howard. In early 1925 she moved to New York, geting with â€Å" $ 1.50, no occupation, no friends and a batch of hope † ( 377 ) . She shortly became an of import member of the Harlem Renaissance, a group of immature black creative persons, instrumentalists, and authors who sought â€Å" religious emancipation † for African Americans by researching black heritage and individuality in the humanistic disciplines. Although sex/gender systems differ cross-culturally, most known societies have used and still utilize sex/gender as a cardinal structural rule forming their existent and conceptual universes, normally to the disadvantage of adult females. Hence feminist bookmans argue that gender is a important class of analysis and that manners of cognition which do non take gender into history are partial and uncomplete. Feminist literature is known by the features of the feminist motion. Writers of feminist literature are identified to appreciate and do clear the differentiation between sex and gender. They think that though a individual ‘s sex is programmed and natural, it is the gender that has been created by humanity, along with a finical penetration about gender functions. Gender functions, they consider, can be changed over clip. The preponderance of one gender over the other is a frequent impression across about all societies, and the world that it is non in favour of adult females is a cardinal, yet obvious, trait of women's rightist or adult females ‘s literature. Here, it is argued that a figure of societies that does non give channels of larning and cognition to both genders equally are non a absolute and nonsubjective society. â€Å" In Search of Our Mothers ‘ Gardens: The Creativity of Black Women in the South ( 1974 ) † by Alice Walker is a great representation of feminism but besides the African American adult females. It is said that these adult females in the early mid-twentiess became more than â€Å" Sexual objects † , in today ‘s society, that stereotype is still about, work forces look down at adult females and looking at adult females like a piece of meat. This quotation mark from â€Å" In Search of Our Mothers ‘ Gardens: The Creativity of Black Women in the South † â€Å" Black adult females whose spiritualty was so intense, so deep, so unconscious, that they were themselves unaware of the profusion they held. They stumbled blindly through their lives: animals so abused and mutilated in organic structure, so dimmed and confused by hurting, that they considered themselves unworthy even of hope. In the selfless abstractions their organic structures became to the work forces who used them, they became more than ‘sexual objects, ‘ more even than mere adult females. † ( Walker 2380 ) This quotation mark can demo that this is how adult females can be perceived as in others eyes. For many old ages it was a punishable offense for African Americans to read or compose, even worse for African American adult females. Life was n't easy for African American adult females yet they kept traditions in their household. The narrative, Strong Horse Tea, by Alice Walker is a dramatic, strong narrative. Rannie Mae Toomer ‘s infant boy Snooks is deathlike ill with pneumonia and whooping cough. Rannie ‘s neighbour, Sarah, tries to carry her to utilize some place redresss to seek to acquire Snooks better without a physician. Rannie is waiting for white medical specialty ; she believes that a white physician will come through the storm that is brewing outside her shaft. The forenoon that Snooks was really sick, she met this mail bearer who she wanted him to convey a physician but he sent Sarah, Rannie ‘s neighbour back over. Finally Rannie listened to Sarah and went out through the lightning and boom to roll up this strong Equus caballus redress. She is determined to salvage Snooks, even as Rannie faux pass and slides through the clay to return with the â€Å" tea † that Sarah needs, the reader is told that Snooks ‘s frail external respiration has already stopped with the boo m. The concluding paradox is Rannie ‘s usage of her leaky plastic shoe to catch the â€Å" tea † and her sealing the cleft by keeping her oral cavity to the toe. All at one time, ignorance is exultant, and Snooks is dead, even the mail bearer is perceived as to be â€Å" nescient † because he does n't understand that Rannie wanted a white physician to be sent to her house. He alternatively delivers Sarah once more to her shaft for her place redresss, the mail bearer does non cognize that Rannie denied Sarah one time earlier. Ignorance is a large subject to this narrative. Alice Walker frequently writes plants in which a black supporter, normally a adult female, is caught between black and white civilizations and surely becomes the victim of both. At her best, Walker neither indulges in polemics nor seeks to blame ; without a uncertainty, here, as third-person storyteller, she distances herself from her characters and allows the narrative to state itself. The consequence of this method is similar to high calamity. The reader of â€Å" Strong Horse Tea, † for illustration, knows that the white physician will non come, that besides Sarah will decline to assist one time Rannie has rejected â€Å" enchantress ‘s redresss † or that Sarah ‘s assistance will likely come excessively late. What comes as a daze is the monstrous shame to which Rannie submits in arrange to make what she awfully hopes will assist her kid. Here, most of all, Rannie ‘s straightforward artlessness comes into its sharpest focal point. Hurston ‘s narrative â€Å" Sweat † depicts an opprobrious and selfish hubby, Sykes. Deliah, Sykes married woman, has taken physical, emotional, and verbal maltreatment from Sykes for more than 15 old ages. Sykes treats his married woman as a grouchy adolescent treats his female parent: with little regard, but still anticipating to be wholly taken attention of. Positively, Sykes has some kind of mother-complex, even preferring large adult females to the skinny Deliah. Though his kept woman is described in an unattractive visible radiation â€Å" a hunk uh liver wid hair on it † ( Hurston 378-87 ) , it could be that Sykes finds bigger adult females attractive because he associates soft curves with a motherly figure. All the same, Deliah does look slightly at bay in her state of affairs because of her race. The work forces in town talk about Deliah and Sykes, to the full cognizant of how he has beaten her for their whole matrimony. Not one of the gossipmongers refer ences to assist Deliah, or naming the constabulary on her behalf. The one thing that works as a impermanent bar against Sykes is when Deliah threatens to name â€Å" the white folks † on him. Would Deliah hold felt as powerless against an opprobrious hubby had her character been white? I think so. Any adult female who takes physical maltreatment for 15 old ages might experience as though she had no other pick but to take the maltreatment for the remainder of her matrimony. However, this warrants studies: A Deliah does look slightly stuck in her state of affairs because of her race. Symbols are current in the narrative, every bit good, extra stressing the narrative ‘s subjects. One of the chief symbols in the work is Delia ‘s perspiration. First, perspiration is the rubric of the narrative, which suggests significance. Delia ‘s perspiration could be viewed as symbolic of all of the difficult work she ‘s done and all of the old ages of fighting she has been through. Her perspiration is a existent reminder of the unsmooth life she ‘s lead. Likewise, another frequent symbol in the narrative is the serpent. In the opening scene of the narrative, Sykes scares Delia with a bullwhip because it looks like a serpent, and he knows that she is scared of serpents. The serpent besides becomes the cardinal constituent of Sykes ‘s secret plan alongside Delia and finally the tool of Sykes ‘s ain expiration. The serpent could typify Sykes, Delia ‘s newborn strength, immorality, or destiny, among other possibilities. â€Å" Sweat à ¢â‚¬  is a short narrative loaded in significance, a narrative of happening strength, redemption, and of karma stuffing a blow. The echt feel as a consequence of the linguistic communication adds an excess bed of command to the relation of this brief but influential narrative. In a short narrative unfavorable judgment by Jelena Krstovis, she talks about Alice Walker and all of the plants she has done, but in the positions of feminism in Alice Walkers ‘ short fictions it is widely known that Walker has â€Å" sympathetic portraiture of predicament of African American adult females. The diverseness of societal fortunes and interior deepness of her female characters have prompted a general reevaluation of black muliebrity among literary and cultural critics. For illustration, they have analyzed Walker ‘s intervention of feminine consciousness in theoretical footings refering female subjectiveness and black individuality development. † ( Krstovis 247 ) It is decidedly shown through Walker ‘s work that she shows female subjectiveness ; in â€Å" Strong Horse Tea † a subject that is described is ignorance of Rannie. Believing in white medical specialty did non assist her babe, Snooks. The ignorance of Rannie being so obstinate, if she had non been so closed minded and listened to Sarah, Snooks may hold been alive. Thomas J. Schoenberg and Lawrence J discuss Zora Neale Hurston ‘s literature in their short narrative unfavorable judgment, Zora Neale Hurston 1891-1960 ; they province under the subdivision Critical Reception, â€Å" Observers have asserted that these and other narratives reflect Hurston ‘s attitude toward racism: she refused to concentrate on the restrictions of the Black experience, alternatively stressing the creativeness and imaginativeness of African Americans and observing her Black cultural heritage. Other critics have explored her word picture of the African American battle with economic subjugation and the relationship between work forces and adult females in her narratives † ( Schoenberg, and Trudeau 42-165 ) It is really true in Hurston ‘s narrative Sweat that the relationship between Delia and her hubby is opprobrious and Delia battles for 15 old ages ever being abused, physically and emotionally. Delia ‘s perspiration is demoing the battle that she goes through on a twenty-four hours to twenty-four hours footing. Though a batch has changed in today ‘s clip, from the narratives of Zora Neale Hurston and Alice Walker, but there is still a cardinal moving ridge of feminism, the company of which one can feel all over the universe. While in the urban scene, adult females have about been known their dues, in the rural scene, adult females are still expected to populate by the stereotypes spread by society. Even in the urban milieus, though adult females have achieved a batch more than society has given them recognition for, they are still expected to carry through certain functions and stereotypes that have been the â€Å" norm † for centuries. Feminist literature of diverse periods will portray different demands and different wants beneath the horizon of feminism. The functions of girls, married womans, and female parents in literature will maintain neutering, and so will their necessities and beliefs. The impression of gender equality that focuses chiefly on adult females ‘s ri ghts has come a long manner, and feminist literature has been a huge medium to convey about any noticeable alterations in the mentality towards adult females. Yet, it is a extended battle that is being fought, and it will be a piece before gender equality and the function of adult females in society will be obvious in the ideal sense.

Retail business - Dissertation Example Secondary research involves using collecting information on a phenomenon under study from existing resources of databases. Secondary research is cheaper relative to primary research. In addition, it takes less time to collect and analyze data in secondary research compared to primary research. Secondary data analysis enables a research to analyze data from large samples. This kind of analyses would be difficult when conducting a primary research due to time and financial constraints (David & Sutton 2004, p.69; Hulley 2007, p. 207). Researchers sometimes utilize primary and secondary research methods in the same study. The information collected from secondary sources in some cases is sufficient to answer all the research questions in a study. This is particularly true for studies that many researchers have analyzed the research topic extensively and the researcher may not add any new insights into the field by conducting a primary research. In addition, sometimes secondary data is the only source of information on a research topic especially when a researcher is not able to conduct a primary research. Secondary data is useful in a research for providing a foundation or background information on the research problem. In this case, secondary data shapes the expectations of a researcher and provides the current level of knowledge on the topic under study (Wrenn, Stevens & Loudon 2006, p. 71; Webb 2002, p. 32). In the proposed study, the information from secondary sources will be sufficient to answer all the research questions. Extensive research has been conducted by independent researchers and those working under government agencies on UK’s retail sector. It is possible for the researcher to conduct a primary research on the UK’s retail sector. However, such a research would be tedious because the retail sector is large. For the researcher to obtain a sample that would be a true representation of the entire retail sector, different organizations in d ifferent industries would be involved in the study. A large sample would be required and this is costly in terms of time spent in collecting and analyzing data from a large sample as well as resource requirement. Researchers use secondary data as a source of exploratory information on their research topics. This exploratory information helps a research in designing research instruments for a primary research. For instance, a researcher may use the exploratory information as a guide to formulating questions in a questionnaire or for focus groups. The nature of existing secondary data on a research topic can help a researcher in making a decision on the most appropriate research design to use in his or her studies. For instance, secondary data may indicate past attempts by other researchers to conduct primary research on a topic and their success or failure. If past researchers have ruled out the possibility of conducting a primary research in a certain filed, secondary data will help a researcher to save time and resources by adopting a secondary research design (Wrenn, Stevens & Loudon 2006, p. 72). The existing literature on UK’s retail sector indicates the significance of the sector to the economy as well as its magnitude. The retail sector is large and consists of very many significant industries. Past researches and government publications indicate its trend over the years including its performance during the financial crisis. This

Compare and contrast two pieces of art Research Paper

Compare and contrast two pieces of art - Research Paper Example It was painted between the years 1829-32 and is one of the most renowned pieces of work by Hokusai. The painting shows a picture of a huge wave intimidating boats all around it, close to the Kanagawa or Japanese prefecture. Most of the times, people mistake the wave to be a part of the tsunami since the disaster is a very common phenomenon near Japan and the Japanese islands. However, it is a wave of the open sea, a commonality in the region of the water body there. Mount Fuji can also be seen in the background of the picture. The dormant volcano has formed a very important part of Japanese paintings and art because of its significance in the environment around the waves. It is also sometimes painted in order to depict the kind of warning the volcano is supposed to show to its audience through a picture portrayal. The picture is also a part of the Thirty Six Views of Mount Fuji and is the first of the series. (Katsushika Hokusai and Japanese Art) â€Å"Washington Crossing the Delawa re† was made in 1851 by Emanuel Gottlieb Leutze. ... his crew helps him cross the Delaware River however many say that the American flag shown in the picture is a symbol of anarchism and does not show American unity. The painting had to undergo restoration after it had been destroyed in a fire and then further again, in a bombing. Other pieces of creative art like poems and sonnets have also been made on the basis of the picture portrayed in the painting, which is one of the best forms of art alive for the depiction of the important event that took place in American history. (Washington Crossing the Delaware) Both paintings have been made with a great amount of detail in their own ways; however the technique used in their creation is very different from each other. The Jap-Asian painting made by Hokusai has been made with the Ukiyo-e technique; this is used for making single brush strokes onto silk or even on paper. It is very easy to make very thin lines and use colour very well with this kind of painting. It helps to give a portrayal of a very simple sketch with deep detailing. The waves in the picture have very extensive detail and the lighting has been worked on fantastically with a cloudy background helping to make the same even more sinister in its own way. The fierceness of the waves has been shown wonderfully, especially with the volcano in the backdrop of the painting. In contrast to the same, the painting by Leutze is more realistic in its approach. It has a very artistic touch and composition to it with excellent lighting and Washington’s face looking at the bright sky and sun, revealing an image along the likes of emerging victorious. The picture according to the painting takes place at dawn with very dark tones all along the sky and the sun rising along the horizon. (Leutze, Emanuel) There are different
