Colon Cancer in Tissue Engineering Literature review

Colon Cancer in Tissue Engineering - Literature review Example The reason being that reconstructive surgery does not replace the biological functioning of an organ or tissue 4. Medical researchers have had to be innovative. Their innovation has led to tissue engineering (TE), which is the initiation of the regeneration of organs and tissues by taking advantage of the individual’s self-healing capability 5. Normally, tissue engineering purposes to control cells to trigger the regrowth of the respective tissue 6. A process that is termed as therapeutic because it replaces the biological role of the damaged or malfunctioning tissues or organs 7. What does TE involve? TE comprises of the artificial stimulation of the capacity of cell differentiation, synthesis, and increase 8. It utilizes two tactics. The transplantation of cells 9 and the use of biomaterials and biomedical machinery 10. In the utilization of biomaterials and associated technologies, there needs to be the creation of in vivo like conditions. What is the purpose of these in vivo like conditions? The in vivo like environment is developed to ensure that the cells are able to boost their differentiation and proliferation to a sufficient standard that allows the biological capability of tissue regrowth 11. Hence, a cell-manipulated natural healing of the particular organ and tissue is attained without the need of transplanting cells. In addition, transplantation of cells is undertaken by transferring cells that have a huge capability for the differentiation and growth of cells to activate the regeneration of tissue in accordance with its potential 12. In this technique, the transfer is done using the infusion tactic 13 or the bolus injection method 14. However, in the use of biomedical and biomaterial technologies, bio signaling and cell scaffolds techniques have been used to deliver the necessary biomaterials that avail the required conditions for tissue regrowth.

What are the motivations of people who become volunteers at major Literature review - 1

What are the motivations of people who become volunteers at major sport events - Literature review Example Literature review for this study has been conducted in the traditional manner by first reviewing literature on volunteering in general and then moving on to the specific subject of volunteering in sports. The barriers and motivation to volunteering both in general and in the sport sector have been evaluated. Data on the economy value of volunteering both in the general and the sports sectors have been reviewed and the dynamics of volunteering evaluated. This section reviews literature on the concept of volunteering in the general sector. The year 2011 was declared the â€Å"European Year of Volunteering† aimed at recognizing the contribution that volunteers make to society (Cattan, Hogg & Hardill, 2011). This demonstrates the value of volunteering in a society and particularly in Europe. The voluntary sector comprises of all activities and services extended on the basis of volunteering – unpaid work in a formal business environment (Gallarza, Arteaga, Floristà ¡n & Gil, 2009). Volunteering services has its roots in a positive attitude that gives rise to the feeling that serving the society or helping people can lead to a higher degree of life satisfaction. However, the definitions of volunteering and volunteerism range from being altruistic to engaging in unpaid activity. Volunteering has been defined as working for no gain (Waikayi et al, 2012), and as an activity that is freely chosen, does not involve remuneration and helps and benefits people beyond their immediate family (Cattan, Hogg & Hardill, 2011; Hoeber, 2010). Definitions from the Australian Bureau of Statistics and Canada Survey of Giving, Volunteering and Participating, Statistics Canada, highlight several key dimensions of volunteering – free choice, formal structure and lack of payment (Hoeber, 2010). The nature of volunteering action can range from volunteering out of free will, being coerced to volunteer or being obligated to volunteer.

Marketing - Essay Example realize a handsome profit and retain relevance in their various industries, all business organizations have to come up with serious marketing strategies. However, advertising is something that is particularly important in the hospitality industry. Hotels such as the Hilton have to keep improving their effectiveness because they are constantly being confronted by the challenge of retaining loyal customers while drawing new ones. The hospitality industries, like others which have been negatively affected by the recession, have had to make significant changes in order to attract customer. It has experienced a lot of fragmentation that makes strategies such as target marketing and market segmentation extremely important. There are different reasons for the changes that have affected the hospitality industry. In the first place, due to the recession, hotels have had to effect necessary budget reductions.1 There has also been change in the lifestyles of many individuals who were formerly in a position to allocate a lot of spending capital on leisure trips. Tourists have developed an interest in a diverse range of recreational activities that create challenges for hotels that are not ready to respect such preferences. Another challenge has to do with marketing expenses. Increased promotional costs mean that hotels have to invest in more cost effective advertising strategies that put more emphasis on the type of services on offer, as well as educational pursuits, than on potential promises.2 To remain competitive, hotels such as the Hilton Group also have to invest in reaching targeted markets, and establishing measurable objectives. One of the biggest challenges in the marketing of recreational facilities lies in the fact that, unlike actual physical goods, recreational breaks have to be consumed on-site.3 Even though hotels may create a spectacular advertisement about the services they offer, the advertisement does not deliver the true experience.

Consequentialism Essay Example | Topics and Well Written Essays - 1000 words

Consequentialism - Essay Example Having to make decisions based on the general welfare of people or its capacity to bring about positive change is justifiable under all circumstances. Consequentialism has been accepted by many realists, who understand that some actions, even if considered wrong with regard to moral rules, may have positive outcomes, benefitting a large number of people, which then justifies the act. The argument presented is to validate the superiority of Consequentialism over other ethical theories in practice. It is important to defend the ethical theory of Consequentialism which can be the key to maintaining stability in the society, without forcing upon them a set of rules to accept as moral standards, giving them more realistic options, and allowing them to decide upon the moral implications of their actions based on its outcome. It requires to be accepted as a moral theory and not an incessant practical casuistry as alleged by opponents of Consequentialism. Standard rules that define moral values are not practically feasible, as many decision making situations may be indefinable in terms of morality. Standard Consequentialism is a theory of decision. It attempts to identify, from a given set of options, the option which is right that an agent should take. The right option to any decision is the option that maximizes probable value or that which will have the best probable consequences, which directly aims at common welfare, which should be the underlying goal of an ethical theory such as in Consequentialism. The function which determines what is the right decision is also the function which ought to be applied in decision-making: it serves at once to evaluate options, and to select them. (Pettit) Consequentialism promotes a more realistic and futuristic approach to define moral standards, implying that, a certain act may be justified by its

Animal Cruelty Essay Example for Free

Animal Cruelty Essay To bring awareness to my audience about animal cruelty. Introduction: As humanity has grown, there has been an increase in authority and rules and regulations of everyday life. One of these rules is animal cruelty. Animal cruelty simply means cruel unjustified treatment of animals and sometimes pets to unnecessary harm and pain. One principal type of animal cruelty is torture. It is not ethical, moral, or legal but we humans do it.. One of the places we see the most animal cruelty is in the circuses. Animals in circuses are regularly and dangerously exposed to many abuses and diseases. Circuses do not practice what they preach and indulge in animal cruelty on a regular basis, after the training sessions of the circuses, tight collars, whips; beatings and torture are the order of the day for these animals. Elephants are one of the animals that suffer from major diseases in the circuses like tuberculosis and can infect humans with the bacterial disease. Some cases show that the elephants were not cured medically for wounds caused during beatings and other natural causes. Circuses have known to keep a large amount of soil ready, to hide the wounds and the blood on the elephants. Some elephants have also suffered from lameness, arthritis and food abscesses. Elephant deaths in circuses are normally caused due to osteoporosis. Elephants suffer from Osteoporosis simply because they do not have wide spaces to move around. Due to the cruel treatments, it has been proved that circus animals are dying at a higher rate than they are breeding. Circuses teach children that its acceptable to abuse and mistreat animals for amusement Another animal cruelty is with dogs, people seem to think that fighting is a dog’s nature. Dogs are not the same as humans, but dogs do feel physical pain. Just because a dog cant say That hurts! doesnt mean they dont feel pain. Dogs also suffer from feelings such as loneliness when left chained. Thats why they howl and bark, to try and get some attention and if they are ignored dogs stops howling, its because hes given up hope. So much cruelty is involved in dogfighting. Dogs are tortured to make them violent. Kittens and puppies are used as bait to teach dogs to kill. Illegal drugs and weapons are usual at dogfights. Fighting dogs usually live on chains their whole lives. Other animal cruelty we see is when they make experiments on animals, like monkeys, mouse, gineapigs etc. Monkeys and others animals do not have identical immune systems as humans, and may not respond to drugs or vaccines in the same way. Animals are often depressed alternatives for humans, and some mixtures that may well cause no harm to an animal, could seriously harm a human being. Also, a drug that is toxic to the animal it is tested on may have no toxicity, and even healing benefits in humans. Pain and suffering still occur, and simply being in captivity can cause great distress to animals, just as it would to a human. We most of the times forget the pain and suffering we are causing to animals, we use them as objects of study, rather than live creatures, and this can mean they are treated as disposable rather than indispensable.

Grapes of Wrath Essay Example for Free

Grapes of Wrath Essay In Grapes of Wrath, John Steinbeck wrote about the Joads and their forced migration from Oklahoma to California. They were forced to leave their simple farming life because of the Great Depression. Through the struggles of the members and friends of the Joads, Steinbeck was able to portray an undesirable, yet accurate picture of America in the early twentieth century. Thus, this story is considered as one of the most powerful social novels in human history. But, Steinbeck did not just describe the country where he lived. In the later part of the novel, Steinbeck crafted a political message that is intended to change the present and unacceptable state of America. In Nobody Knows My Name, James Baldwin wrote a series of essays about the experiences, thoughts, and struggles of an African-American deep in the heart of Europe. The collection of essays appears to be a rite of passage for Baldwin who did not want to be labeled as a Negro writer, but simply an American writer. But, through the series of essays, Baldwin wove together his own political message, which wanted to radically shift the point of view of society about what America is all about. In both pieces of literature, it can be found that the written works of art are not just mere expressions of the authors’ creativity. This is because a simple creative expression is wandering and aimless. The written art is similar to a powerful sword that can be wielded to effect political and social changes, but this figurative sword obeys the authors’ personal views that are derived from their personal experiences. Despite the personal basis of the authors’ opinions, the political nature of the written art is needed in societies that are thrown in the midst of division and conflict because the political nature of written art serves as a guiding beacon of light, both for the ordinary citizens and for the political leaders. Steinbeck’s Grapes of Wrath has many interpretations that originate from varying perspectives, such as religious, economic, social, political, and personal. The same could be said of Baldwin’s Nobody Knows My Name. Different and numerous interpretations of literary works are acceptable because that is the nature of all literary works and the authors could not be confronted and asked to choose which interpretation is the most accurate. It is probable that Steinbeck purposely wove a novel that is a mosaic of several messages. And it is also probable that Baldwin delved into different issues and each essay in the said collection might be about more than one perspective. But, in comparing the novel and the essay collection, the two perspectives that will be analyzed are the similar personal and the political beliefs of the authors about the American society. Both Steinbeck and Baldwin see a divided American society. In Steinbeck’s novel, the division is between the rich and the poor. This division is felt sharply in the Great Depression when the rich and powerful preyed on the desperation of the poor people. The reputed rich grape vineyards in California became attractive to the Joads and other poor people who are suffering the pangs of hunger due to the poor harvest. The house was dead, and the fields were dead† (Steinbeck, 135). The family chose to uproot themselves and went to California. But, the vineyards did not deliver the promise of providing enough food security for the people. Instead, the Joads toiled hard, day and night, but remained poor, oppressed, and discriminated. In Baldwin’s essay, the division is between the Blacks and the White. The Civil War has ended but the discrimination against the Black Americans remained. Many Americans gave lip service to the concept of equality and assimilation, but it is far more difficult to remove the generations-old dogma of Blacks being an inferior race. Hoping to achieve the desired state of equality, the Blacks fought by excelling in the fields of sports, music, and literature. But this was not enough. Instead, the Blacks continued to endure discrimination. The nature of the division that was described by Steinbeck may not be exactly the same as the division described by Baldwin. But the division and the conflict are strongly felt. And because of the presence of the conflict, America is not united. Unfortunately, there are more conflicts that exist other than the conflict between people of different races and people who come from different socio-economic status. There are conflicts based on gender, education, and sexual orientation. â€Å"The tensions of American life, as well as the possibilities, are tremendous† (Baldwin, 11). But what could be the long-term implications of having a divided country? Both Steinbeck and Baldwin predicted that the present divisions in America would lead to overwhelming wrath that might destroy society. In Steinbeck’s novel, the poor finds that many of their opportunities are kept away from them or wasted away by the rich and powerful. â€Å"The people come with nets to fish for potatoes in the river, and the guards hold them back †¦ in the eyes of the hungry there is a growing wrath† (Steinbeck, 477). It is suggested that the travels of Steinbeck revealed to him the desolate state of his country and the increasing resentment of the poor. In Baldwin’s essay Fifth Avenue, Uptown: a Letter from Harlem, he described the rotting and festering social situation of Harlem, the corner of the world where he grew up. Baldwin drew upon his experiences and observations when he was still living in Harlem to create this essay that depicts the oppression that the Whites wielded through the police. The policemen â€Å"represent the force of the white world the black man corralled up here, in his place† (Baldwin, 57). The Blacks have began to realize that they were being discriminated and that the basic right to human dignity was been taken away from them through the selfish and callous way that the Whites treated them in the past decades. But, instead of being apologetic, the Whites, being the majority, demanded assimilation. It would be inevitable that the Blacks would feel resentment. And with resentment, there would be a burgeoning anger. Steinbeck and Baldwin are personally aware of the negative effects of the existing conflicts in their societies. They knew that anger would be fermented. There is a limit to the patience of the people who are being oppressed. What then should Americans do with the existing conflicts in their country? Both Steinbeck and Baldwin personally believed that there must be a radical political change in the country, but for any radical change to happen, there should also be a radical change within each individual American. In Steinbeck’s novel, there were many characters that underwent changes throughout the story. However, the character that underwent the most radical change was Rose of Sharon, who, after suffering from the loss of her own child, has agreed to nurse an old man. â€Å"Then she lay down beside him. He shook his head slowly from side to side. Rose of Sharon loosened one side of the blanket and bared her breast† (Steinbeck, 619). This last scene in Steinbeck’s novel often elicits a violent reaction from readers. But, upon reflection, it was the most humane act of all. The violent reaction occurred simply because many readers are trapped within the bounds of society’s conventions. Without these conventions, the readers will be rid of preconceptions that prevent them from reaching out to other people. Without preconceptions, the division between the poor and the rich would eventually disappear. In Baldwin’s essays, the personal change that he wanted to obtain is to prevent the self from following the tides of anger that will sweep and destroy the country. Thus, instead of wearing the easy cloak called Negro writer, he chose to create a new one, the American writer. He found that the American writers of his time lack the sense of purpose that a literary artist should have. This is because the American writer, similar to the many readers of Steinbeck, is trapped by conventions of society. Baldwin believes that unless the American writer â€Å"is released from the habit of flexing his muscles and proving that he is just a regular guy that he realizes how crippling this habit has been† (Baldwin, 6). If all Americans will remove the concept of race from their minds, they will find that there is no Negro problem after all. The concept of effecting an individual change prior to achieving a wider social change evolved primarily from the personal experiences of the authors and from their observations. These were distilled to create the plot of the novel and the subject of the essays. As influential authors, were Steinbeck and Baldwin ethically appropriate in creating literary works that came from their personal experiences and personal political beliefs? The answer is an affirmative. The literary artist must take his own personal history, distill truth from his experiences, and use his insights responsibly by sending a political and social message to the rest of the world.
