Embryonic Stem Cell Research Essay Example

Embryonic Stem Cell Research Essay Nowadays, because of the technology and the remarkable evolution, there has been a solution for everything. Especially the many solutions that newly emerging for different diseases of our modern times. One of those deployed solutions in our present is the transportation of organs such as transplanting heart, liver or even the transfer of stem cells tissues. Stem cells used to cure many diseases and save lives of many people. When it comes to transplantation of stem cells, scientists usually get stem cells from two sources from either embryos or adults. The main disaster that scientists and doctors are facing it, is that getting stem cells from the embryo leads inevitably to his death without a prospect of survival. This leads to depriving one of life versus someone elses life. That is why many governments around the world have differed about the transplant of stem cells from embryos. Some governments prevented sacrificing embryos for others lives; other governments legalize and allow the transplantation based on medical research, ethical aspects, and government policy. Medical research has proven that stem cell transplantation affects both the involved embryos and victims of diseases who are in desperate need of these cells. Some people may argue that governments must not allow the uses of embryonic stem cells; they think of the ability that scientists have nowadays to find solutions for these malignant diseases without touching embryos. Especially in our present, where technology and advanced tools were available for scientists in order to facilitate their work. For example, applying the new researches that focus on the eradication of stem cells without any harm to the fetus. Although, scientists can work on it until it become more suitable for applying it to humans without the loss of more lives. However, doctors do not have the patience to wait for the expected results of this research.

Free Essays on Living A Dream (Descriptive Essay)

Living in a Dream July thirty-first, summer, not too hot, not cold. Brian is eighteen years old, five foot eleven, brown hair, green eyes, full of energy and looking forward to tonight’s events. Brian is going camping with three of his close friends: Dan, Kate and Julie. Like a typical group of eighteen year olds, this is not just some â€Å"let’s roast marshmallows† camping trip. They have plans to have an experience of a lifetime, an experience that cost them forty dollars. As far as they are concerned it is forty dollars well spent. Seven o’clock PM and it’s been one hour since Brian and his friends ate the forty dollar dried mushrooms. When they ate the mushrooms they instantly noticed a horrible taste. They did not taste anything at all like one would expect forty-dollar mushrooms to taste like; but they didn’t buy these mushrooms for taste. The mushrooms tasted horrible, bland at first and when the after taste kicked in they actually tasted like crap. Why shouldn’t they? They were grown in cow pies. It has taken an hour for Brian to finally understand why his money was so well spent. The campsite is so high up on the mountain that they escape the clouds seen below them. The sun is beginning to set and Brian decides to go watch it. He is sitting in a folding chair in a field of tan waving grass that continues out twenty feet beyond him and drops off with the rest of the mountain. The air is calm and beginning to cool. As Brian sits in his chair he is overtaken by immense relaxation; thoughts of getting up any time soon have escaped from his mind. Brian slouches down in the chair to make himself more comfortable. He is feeling a strange buzz throughout his body, almost a tingle but not quite. Right when his body becomes nearly completely relaxed he suddenly becomes very tense. He is now starting to shake; he feels he is in control of it, but can’t manage to stop it. His body continues ...

Difficulty of Predicting Terror Attacks in the United States Essay

Difficulty of Predicting Terror Attacks in the United States - Essay Example The paper explores the reasons that make the prediction of terror attacks in the United States a difficult affair. Difficulty of Predicting Terror Attacks in the United States Introduction Modern times have witnessed a transformation of terror groups into barbaric and more determined groups. The present terrorism model differs from the previous models as it is characterized by loosely articulated political objectives, indiscriminate attacks, and efforts to attain maximum psychological and social disruption. The differentiations between the present and past models have left serious gaps in preventing and disrupting terror attacks. This has come in the backdrop of a growing Islamic resentment of the United States, which has become entrenched within the world. The significance of understanding terrorism in the United States was heightened in the wake of 9/11 attacks. America’s sense of immunity to large-scale terrorist attacks within its own borders suffered a massive blow with 9 /11 attacks. The attacks were a traumatic awakening to America. The success of the 9/11 attacks was grounded in three prominent capabilities that terror organizations such as Al-Qaeda still retain. These include the capability to exploit vulnerabilities of the enemy, effective employment of deception, and the application of suicide attacks to enhance success (Bullock, Haddow & Coppola, 2012). Despite the focus, little is known about general patterns of terror attacks within the U.S. Terrorists have honed their capability to gather intelligence, employ technology, and identify security gaps. As a result, predicting terrorist activities has become a tall order. Making assessments on future likelihood or consequences of terror attack is in essence an elusive undertaking (Pillar, 2011). This is mainly compounded by the fact that there are limited statistical data detailing terrorist attacks from which to parameterize terrorism risk. Besides, relevant variables influencing terror underta kings such as target type, weapon type, and target (geographical) location are hard to pin point. Terrorist threat is perpetually changing in ways that make it dangerous and difficult to counter. While most terrorist activities were traditionally confined in conflict- prone areas, especially in the last decade, terrorist activities have attained a global dimension. The main focus of terror attacks centre on inflicting massive civilian casualties and causing lasting economic damage. This propels the urgency in attaining capability to predict and pre-empt such attacks (Forest, 2007). The impact of terrorist attacks in the society has been so severe to the extent of becoming imperative to predict and disrupt the attacks. Most of the successful terrorist attacks exhibit common features such as meticulous long-term planning, cautious target selection, access to destruction means, and effective support in terms of logistics. The overriding question in those circles is not if but when. Irr espective of the mode and scale of attack, few Americans doubt that time is quickly running out. Nevertheless, this view tends to be contestable and may even be exaggerated. It is difficult or even impossible to predict terrorist intentions. Indexing of potential terrorist attacks is based on criteria such as motivation of terrorists, presence of terror groups, efficacy of the groups in undertaking terror acts, the scale and frequency of previous

Does the research evidence support using caesarean section for Essay

Does the research evidence support using caesarean section for reducing mother to baby transmission of hepatitis C during labour and birth - Essay Example y Armstrong and his colleagues, the incidence of Hepatitis C infection in the US escalated from zero to 44 cases for every 100,000 individuals before 1965. The prevalence of the disease reached its peak in the 1980’s when the incidence of HPV infection became 100-200 per 100,000 individuals (Armstrong et al., 2000, p. 779). Although HCV infection in most patients is asymptomatic, several cases demonstrate certain symptoms including jaundice, fatigue, myalgia, low-grade fever, right upper quadrant pain, nausea, or vomiting (Moore et al., 2001, p. 658; Maheshwari et al., 2008, p. 325; Webster et al., 2009, p. 110). If not given appropriate medical attention, hepatitis C often leads to liver fibrosis, liver cirrhosis, hepato-cellular carcinoma, and liver damage (Vogt et al., 1999, p. 868; Moore et al., 2001; 657; Geller and Herman, 2006, p. 88) The most efficient mode by which the virus is acquired occurs via repeated and direct percutaneous exposure to infected blood and organs from unscreened donors, exposure of blood through the use of contaminated medical instruments, injection drug use, and haemodialysis procedures (Lavanchy, 1999, p. 147; Bartolotti et al., 2007, p. 784). However, with the advent of better needle exchange programs, blood donor screening, hygiene care, and education among injecting drug users, a significant decline in the prevalence of Hepatitis C has been reported since the 1990s (Armstorng et al., 2000, p. 779; Geller and Herman, 2006, p 86). Another route by which HCV infection can be acquired is through vertical transmission ( e.i. passive acquisition of the virus by children from infected mothers) ( Kudo et al., 1997, p. 225). The actual mechanism of mother-to-child HCV transmission is not yet known, but exposure to infected mucous, fluids and blood from the mother significantly increases the ris k of transmission (Indolfi and Resti, 2009, p. 837) According to Plunkett et al. (2004, p. 998), the highest prevalence of Hepatitis C occurs

Material Review Essay Example | Topics and Well Written Essays - 1000 words

Material Review - Essay Example The game is easy to ply, and any child despite their proficiency in English finds it easier and fun. For such bilingual students, the instructor can start by saying â€Å"I spy with my little eyes something green† in the students native language, and then the child is supposed to guess what the teacher would be referring to. Such cycle is repeated over and over; the things the teacher refers to once identified can then be given English names to enable students to comprehend such items in English as well as connecting to their native language. The creator of the game has published numerous books that have helped students in grasping such concepts much easily. The class room has 20 students between 9 and 11 years at grade 5, and the students are proficient Spanish speakers. Students have enrolled for an English lesson, while most of them are first and second generation immigrants from Spain. The reason behind selection of this game is its great importance in involving students i n the learning processes, improving the thinking capacity of a child, and connecting between written, verbal, and visual elements in the learning process. ... Such materials will therefore help such young leaners to connect between their native langue and English, and comprehend such meanings, which will be a major step towards learning English. The material chosen for the lesson is appropriate as it will enhance creativity and improve thinking among students. At grade 5, such students should have an ability to communicate using images and portray creativity in the learning processes as well as use of selected principles and elements in creating images according to certain defined criteria (Ministry of Education, 40). Therefore, the learning material is aimed at enabling students to reflect on items in their own native language and translate such reflection into English langue, which will enable them to grasp the basic concepts verbally and in written format. Freeman and Freeman (36) argues that the key to acquisition is receiving messages that we understand; implying that understanding directions in a foreign language will require the stu dent to make meanings in their own language first. The specific context of the lesson will involve enabling students to grasp concepts in a foreign language, and connect such learning to their own language. Therefore, at first the instructor will lead the class by initiating the â€Å"I spy† game, pinpointing visible elements in the compound in Spanish, where students will be required to identify the specific elements; the instructor writes them down both in Spanish and English. Freeman and Freeman (36) argue that students will acquire ability to read and write the same way they acquire a second language. In writing the names of the elements identified by students in both

The Esl Website Evaluation English Language Essay

The Esl Website Evaluation English Language Essay The ESL website address that I am evaluating is http://a4esl.org/. This website is attempted to teach English Language and to help learner learn English as a Second Language (ESL). It is an approach to language teaching and learning and computer technology is used as a study aid. This ESL website is known as the Computer-assisted language learning (CALL). In the recent years, we could perceive the development of computer technology thus CALL is widely used as the supplemental instruction method to the teachers and the students. CALL supplements teachers and learners with the comprehensive exercises and those exercises are as stimulation to the teaching and learning process. It contains activities for ESL Students such are quizzes, tests, exercises and puzzles. As I browsed to the home page it listed the specific area that learner needs to work on. For examples, the grammar quizzes, vocabulary quizzes and crossword puzzles. In the main topic contains the level of instruction such as e asy, medium and difficult. In regards to learning the content, the application user shall determine which types of quizzes he or she interested to learn, for example if the learner likes to work on grammar, he or she will click at the grammar quizzes activities and choose the activities depends on the learner level of proficiency either you are in the beginner, intermediate or advanced level. The ESL website http://a4esl.org/ provides the users with varieties types of exercises such as multiple choice questions, close passage, fill in the blank and many more. In order to operate the computer, users should have the basic knowledge of terms related to a computer. How to operate a computer; switch on, using the keyboards and know how the functions of the keyboard. Users have to be familiar with the software in which using in the computer, for example Microsoft office. By getting an access to the website, the users should know how to connect to the internet and what sort of gadget used for connectivity. The users need to know how to browse to the internet explorer and search for the ESL website. For example, http://a4esl.org. and other website which is available and appropriate for learning English as a second language. I, sometimes did access with the ESL website but different from http://a4esl.org. However, the concept is laying the same objectives. Bear in mind, that learners have obtained the multisensory in learning therefore this application is able to evoke learners attention by stimulating their multisensory perceptions. No doubt, I would say that similarity concept for application for teaching and learning ESL is accumulating comprehension to English language and they are using style of drilling in their exercises. In addition, the exercises created in this website are more comprehensive compared to our textbooks that are used in schools. The exercises that have been created in the program are designed as in the form of parts of speech. Parts of speech are the basic types of words of English grammar. It has eight categories and the words in the eight categories are used to form patterns of English grammar and syntax. I have come across the Classical Method in teaching the language. The method is use in the application to be understood as the theoretical finding and positions and it is thought of as theories in practice. As mentioned by Brown (2000), Classical Method is focused on grammatical rules, memorization of vocabulary and of various declensions and conjugations, translation of texts, doing written exercise (Pg 15). For example, the grammar quizzes exercises in this application are letting learner apply their basic knowledge in grammatical rules; to apply appropriate tenses to the answers. Learner is not being taught for fluency but more emphasize on accuracy. Furthermore, Krashens theory of the language acquisi tion hypothesis focused on two fundamental theories of how individuals learn languages. According to Krashen, the acquiring of language divided into two systems that are independent but related. It is called the acquired systems and the learned system. Krashen privileges the acquired system when speakers are less concerned with the structure of grammatical rules and speak naturally. Contrary to the learned system, when learners engage in formal instruction likes studying the rules of syntax. Therefore, this website http://a4esl.org/ is precisely concentrates on the rules of learning the English language or so called emphasizing on the accuracy. Learners are taught by drilling and practicing from the activities. This website is seen as practical activity to English learners as it is easy access, varieties of activities and exercises and contain of listening, writing and reading skills. The overall principle of constructivist theory of learning is defined as an active process by accepting learner autonomy and focuses on learners. Learners need to be motivated in their learning process hence to variety their learning is by teaching different activities in classroom. Learner autonomy is the learner responsibility for his owns learning by having curiosity, initiative and persistent especially in using technology. In the constructivist theory, teacher is the facilitator and guidance for counseling and show direction. Hence, software is as alternative tool to reach learning goals besides the traditional way of learning English using textbook. This website encourages learners to explore what is internet access and the ESL website plays it part as simulation and modeling to learners learning process . As a result, learners are not bound to the same activities in the classroom such as learning is only based on the textbooks. I am not denying of the vital use of the technology in learning process. However, I am concerning more on the proper guidance by the teacher if it to be used in schools. Teachers have to take into account on students attention span. What if say they are bored with the application. I suggested the ESL website is used once a week to test the students understanding in a usual lesson in the classroom. Alternatively, students have the freedom to browse the ESL website when they are at home as drilling and practice. Teachers are still needed to clarify items that are not understandable. Also, teachers are needed to the situation of encouraging the authentic conversation as sometimes software application is rigid. The users do receive the answer instantly but in the form of explanation rarely not provided. This ESL website is useful to me as for now and the future work. I have no problem in operating the software and other application. Second, I like the external links in the website: http://a4esl.org.when it provided learners with numerous topics of an audio listening and speaking exercises. Third, this website is applicable and appropriate to all levels of proficiency that both school learners and adult learners can use these activities. This ESL website http://a4esl.org covered almost everything in English learning and teaching process. However, in the main topic grammar easy quizzes, there is no box to tick or click the answer that we want to answer but it supplied learners with answer straight away. Therefore, learners might peep to the answer immediately without an effort to solve it first. Hence, I suggested that all questions should supply with boxes for the users to tick their answers, and after finished answering than they can check for the correct answers. As for the sub topic error correction, the activity is to correct the mistake in the sentences given. However, if the users give the wrong answer it does not explain why the users did wrong in terms of grammar usage. It is recommended to supply the users with grammar explanation if users get the wrong answer so at least users are aware of the mistakes and understand the correct grammar rules to form the sentences.

John Grishams A Painted House Essay -- Essays Papers

John Grisham's A Painted House John Grisham’s book, ‘A Painted House’ places the reader within the walls of a simple home on the cotton fields of rural Arkansas. Within the first few pages, the author’s description of the setting quickly paints a picture of a hard working family and creates a shared concern with the reader about the family’s struggle to meet the basic needs of life. The description of the dusty roads, the unpainted board-sided house, the daily chore requirements and their lack of excess cause the reader a reaction of empathy for the family. Although the story takes place in a dusty setting very unfamiliar to most readers, the storyline is timeless and universal. Most everyone has a desire to meet the basic needs of life, embrace their family ties, and make others and ourselves proud. The crux of this book is that it does an excellent job in showing the reader through other’s examples and hardships to persevere and never give up. The title of the book, ‘A Painted House’ is based on the actual farmhouse in which the Chandler family resides. It was an old house. It was a fine house that had never been painted. For this particular family, paint - like eating meat with every meal - was a luxury. It was not a requirement to have a painted house. It was not a sign of laziness as the reader might initially expect. It was a sign of being frugal with money. In this bold example of persevering and never giving up, Mr. Grisham demonstrates to the reader that ’one can’t have everything’. The story is told through the eyes of seven year old Luke Chandler. Luke lives with his parents and grandparents on their rented farmland in the lowlands of Arkansas. It takes place during the harvest season for cotton in 1952. Like other cotton growers, these were hard times for the Chandlers. Their simple lives reached their zenith each year with the task of picking cotton. It’s more than any family can complete by themselves. In order to harvest the crops and get paid, the Chandlers must find cotton pickers to help get the crops to the cotton gin. In order to persevere, they must depend on others. They find two sets of migrant farm workers to assist them with their efforts: the Mexicans, and the Spruills - a family from the Arkansas hills that pick cotton for others each year. In reading the book, the reader learns quickly that l... ...ily is residing in the Chandler barn where the Mexicans first stayed. Luke and his parents are traveling to Michigan in order for Luke’s father can find a job in a automotive assembly plant, and Luke’s grandparents are staying at the old farmhouse with the hopes that the whole family will be back together soon. The hope from the reader is that all of the book’s characters will someday find true happiness. These folks work hard and our characters seem to deserve more than they currently have. Most readers can appreciate this feeling because it’s a feeling shared by everyone. In regards to the unpainted house: At the end of the book, only a corner of the house needs painting to be complete. It would have been very easy for our author to have completely finished in painting the house. However, that’s not what the premise nor the promise of the book contains. There is a big difference in completing a challenge, and being successful. Although life’s problems and challenges are never ending, the success in dealing with a challenge has more to do with the way it is done than in its completion. ‘The joy is certainly in the journey’ when reading the novel, ‘A Painted House’.
