Cloning - Essay Example ifferent contexts in biological research but in its most simple and strict sense, it refers to a precise genetic copy of a molecule, cell, plant, animal, or human being. In some of these contexts, cloning refers to established technologies that have been part of agricultural practice for a very long time and currently form an important part of the foundations of modern biological research† (Nussbaum & Sunstein, 1998, p. 1). Although this method has created many live successes, it has proved significantly less likely to generate successful instances of pregnancy than those conceived naturally via sexual intercourse. Additionally, the majority of cloned mammals have had some form of birth defect. Mammals do not replicate their own DNA through the natural process. This occurs only by cloning which presents both scientific and ethical implications. â€Å"The prospect of such replication for humans has resulted in the most controversial debate about reproduction ever to be taken up in western civilization† (McGee, 2001). Plants create offspring through replication by the natural method. When mammals replicate DNA by artificial means the practice is complex both technically and socially speaking. Those who are in opposition to cloning humans contend that this unnatural form of reproduction has a tremendous potential for basing dubious procreation decisions with regard to the genetic engineering of children. Their worry is that the traditional family is in jeopardy of evolving in a bizarre, unfamiliar and socially undesirable direction. Supporters of cloning procedures say that it may possibly, among other attributes, serve society as a valuable alternative infertility treatment. The cloning of animals has provoked the debate regarding the social, legal and ethical aspects concerning human cloning. Because of failure rate as compared to the customary conception method in animal testing, scholars, scientists and politicians usually agree that human experiments

Public Relations in college Athletics Essay Example for Free

Public Relations in college Athletics Essay Public relations play important role in linking college athletics with other colleges and news media. It represents college athletics related issues to media level. Public relation is responsible for handling all communication and information exchange between the college and athletics and media. It also promotes and develop relations with other colleges and universities.   Public relations will also keep news site updated to keep inform the community about the current issues, updates and goals.   Public relation program will handled all media related inquires, it regularly updates about recent research carried out in the faculty, promote inter-colleges sports and workshops, other promotional programs in the community and many other activities on the campuses.   Public relation facilitates inter-departmental, inter-community and social relations.   Assessment:   College athletic public relations goal is to develop such programs to maintain good public relations with the community and to promote student athletics sports, moral, physical, social and emotional growth. Such programs will keep individuals involve with creative activities and simultaneously promote their social relations with the community, a sense of responsibility and increase their morals.   Plan or board policy in relation to an existing public relations/marking plan or program One of the main purposes of the public relations is to let the students and community learn college rules and regulations and respect it in all circumstances in order to provide well-balanced education and creative skills.   Public relations board will responsible for making new guidelines and policies for people especially parents and guardians to keep them update of regulations and procedures.   Public relations board will develop such policies in order to keep details of all programs and guidelines for the community, guardians and students. The policies must define and update the student’s and communities needs. It must also prepare information regarding programs to give student and guardians full information. Evaluation: According to a recent research (Parry and Hayden, 1993) postgraduate students benefit from the program only when these students are paid attention separately, faculty and departmental staff clearly verify the assistance these students should receive. For recruiting more students in postgraduate program following strategies are needed to be implemented in the new curricula. These strategies are formed after careful analysis of the problems that were faced by the students, which were causing decline in students’ strength in the university. Creative ideas were generated to find out various possible number of solutions for the prevailing problems.   Recruitment and selection of students   There is a need to develop a unique workable policy for accommodating minimum or maximum number of students in the postgraduate program on the basis of preferred recruitment practices and on the university standards to recruit students per class.   There is also a need to start scholarships for students who are unable to pay their full fee.   Technical expertise and competencies in their language should be considered mandatory prior to admission.   Apart from quantitative analysis of students’ recruitment, university should also consider the qualitative approach to recruit students. Thus, admitting those students who are skillful and eligible for the program. And who will prove to be good in giving out results, thus, improving the standards of university in terms of qualitative education.   Audit of an existing safety or crisis prevention plan Staff and supervisors All staff and supervisors should be highly qualified and experienced. Per supervisor and staff, students allocated should be evaluated. Number of supervisor allocated per faculty should be evaluated New developmental strategies for students, supervisors and staff For every student there should be a clear statement for the academic mission of the university and department, research achievements, focus of teaching at the university, discipline rules that are to be followed. Every student should have a clear idea about departmental activities, social and intellectual prospects, facilities, resources, services, support, research facilities, and other procedures. In addition, there should be accommodation facilities, offices for mail typing, laboratory space, technical support, research equipment, computerized infrastructure, photocopying, library facilities, telephone, email and facsimile facilities, research grants and paid work. All above mentioned facilities should be publicized among undergraduate students, who might get interested in taking admission in postgraduate. Recent research showed that postgraduate students find various elements useful such as outline of the research they are taking, opportunity to meet other postgraduates, academics, administrative, technical staff and faculty. Selection of topics should be made easy and should be in consistent with the research facilities and financial resources available in the department. Each student should be guided individually that how they have to conduct research. Each student should be encouraged to acquire specialist assistance in writing thesis, computing, analysis of data, researching in library and archives in the management database. Using recommended assessment techniques,    There should be regular meetings and discussions between the supervisors, other research students for keep check on the progress of work and new innovative ideas that research students might learn from each other. Each student should keep a record of his or her work. Similarly, each supervisor should keep record of their supervision to avoid any misunderstanding between student and the supervisor. There should be brief records of meetings, discussions, deadlines set for the accomplishment of certain task or research work, notes on advice provided to each student, photocopies of other important notes, drafts and student diaries. Working relationship with other students should be kept in harmony. Students should have opportunities to mix socially with other departmental students. There should be network of students to get mixed with each other and learn each other problems, research and learning abilities. Progress of each student should be completely checked. There should be a definite policy to monitor the continuous progress of students. There should be new developmental policies to provide financial assistance for research and other postgraduate students. Each student should keep participating in conferences, seminars and colloquia for sharing their knowledge with other research scholars of the same fields. Create an assessment tool to evaluate a program,    The program’s success depends on individual outcomes, hence, it is important to judge whether these outcomes are worthwhile or just achieved. The desired outcomes of this program are listed below. It will improve motor skills of a student and he would improve his locomotive and perceptual motor skills The program will enhance their learning and memorizing capability. A student will be able to give more attention to his studies. The student will develop better social relations. He would be better off in school and at home. Student’s emotional and psychological development will improve. Emotional problems are usually correlated with his physical, social and cognitive development. But as his cognitive, social and physical development enhances, his emotional development will improve. The program will improve quality of education at school. The student after being trained will have better skills to interact with his environment and will yield better results. The program is cost effective and will safe cost of future problems that may arise due to lack of education and training at this age. The program will speed up student’s cognitive development. The program is not offered for a specific need but it will improve overall development and generalized needs of a student. Teachers and trainers will find it easier to train through this program rather than typical way of teaching. â€Å"Building and modeling caring relationships is crucial to the preservice teachers capacity to receive curricular content and their ability to teach that content to young student.† (Lake, Jones, Dagli, 2004) The program would be able to preserve social and morel values through better education and training of a student. As student are major and most crucial beings in transmitting such values. The program protects student’s right to live and develop to their full potential while benefiting from the environment.

Since its first documented use in 1943, lysergic acid diethylmide, or LSD, has grown to be one of the most potent and controversial drugs in society today. The ways in which LSD produces its effects within the brain is still unknown, and no practical use has been found for it. However, this substance has been described to give incredible insight and revelation to some of those that have taken it, although others have had frightening and nightmarish experiences. LSD is an unpredictable and possibly dangerous substance, but can and has changed the lives of many. A Swiss chemist named Dr. Albert Hoffman first produced lysergic acid diethylmide –or best Known as LSD in 1938 (Dye, p. 2). Hoffman discovered the drug while trying to synthesize a new drug for the treatment of headaches. He obtained the lysergic acid from the parasitic fungus that grows on rye plants known as ergot. From the lysergic acid, he synthesized the compound LSD. He used the compound to test for its pain killing properties on laboratory animals. Being that appeared totally ineffective, the bottle of LSD was placed on a shelf and remained untouched for five years. On April 16, 1943, Dr. Hoffman decided to do further research with the LSD compound (Dye, p. 5). While handling the drug, he accidentally ingested an unknown amount. Then he experienced the world’s first LSD trip. About eight hours later Hoffman drifted back into normal reality and the Psychedelic Revolution was born. Three days later, in an attempt to prove that the previous episode was indeed caused by the ingestion of LSD, Dr. Hoffman ingested what he thought would be a small quantity of LSD, 250 micrograms. In actuality, this is approximately five times the dosage necessary to produce heavy hallucinations in the average adult male (Solomon, p. 34). The drug produced effects that were much more intense than the first time Hoffman took the LSD. He noted that he felt unrest, dizziness, visual disturbances, a tendency to laugh at inappropriate times, and a difficulty in concentration (Dye, p.7). Dr. Hoffman’s condition improved six hours after taking the drug, although visual disturbances and distortion continued. LSD was first shipped to the United States in 1949 (Solomon, p. 54). American scientists tested LSD on animals to learn of its effects. It produced dramatic behavior changes in all animals investigated. During the 1950’s, experimentation of LSD on humans began (Solomon, p.

Benedick and Beatrice in “Much Ado About Nothing” Essay

One of the most important aspects in â€Å"Much Ado About Nothing† is the story of love. It is often the basis for what transpires throughout the play and can most easily be seen through the relationships between Hero and Claudio, and Benedick and Beatrice. During the play the reader learns a lot about these couples as well as how they possess some of the same relationship traits whilst still seeing the obvious disparities between them. Benedick and Beatrice represent a â€Å"love/hate† relationship. They share many things in common and both are cynical of love and marriage. They are witty intellectual and not at all shy, which leads to many wars of words between them. In the beginning of the novel, the hate between this eventual couple is evident. Beatrice says to Benedict, â€Å"I wonder that you will still be talking, Signor / Benedict. Nobody marks you†. Benedict comes back with, â€Å"What, my dear Lady Disdain! Are you yet / living?†. Although Beatrice and Benedict may have no idea; the fact that they love each other must be evident to the rest of the characters. Otherwise, their friends and family would not have tricked them into admitting their love. Claudio and Hero represent a more romantic relationship. Claudio finds himself in love with Hero upon coming back from battle and he is not ashamed to admit his love for her. â€Å"I would scarce trust myself, though I had sworn the contrary, if Hero would be my wife†. This leads to Don Pedro assisting in Claudio’s proposal and gaining Leonato’s acceptance. Claudio and Hero’s love is mostly based on looks, since they did not know one another very well before Hero accepts Don Pedro’s proposal to marry Claudio. The fact that they don’t know each other means that there is little trust between them and this is exploited when Hero is accused of being unfaithful. Claudio is also extremely gullible and jealous and that is why he shames Hero at their first wedding. Although there are many differences between the two couples there are also some similarities. Both couples had to deal with obstacles that they would not have overcome without the help of others. Beatrice and Benedict would still be arguing if their friends did not trick them into thinking that they were in love with each other. They would not have realized that their  constant bickering with each other translated into loving emotions. Claudio and Hero’s relationship is broken when Hero is accused of being unfaithful but with the help of Dogberry and Verges, it is revealed that the accusations are not true. This allows Claudio to clear Hero’s name and marry her in the end. An obvious similarity between the relationships is that they both accomplish love.

Collagen and Extraskeletal Disorder

Osteogenisis imperfecta (OI) is â€Å"a rare genetic disorder of collagen synthesis associated with broad spectrum of musculoskeletal problems, most notably bowing and fractures of the extremities, muscle weakness, ligamentous laxity, and spinal deformities. † (Binder, 386). Other collagen-containing extraskeletal tissues, such as the sclerae, the teeth, and the heart valves are also affected to a variable degree. OI has a â€Å"common feature of bony fragility associated with defective formation of collagen by osteoblasts and fibroblasts. (Smith, 1983, 13) This disease, involving defective development of the connective tissues, is usually the result f the autosomal dominant gene, but can also be the result of the autosomal recessive gene. Spontaneous mutations are common and the clinical presentation of the disease remains OI is most commonly referred to as â€Å"brittle bones†, but other names include: fragilitas ossium, hypolasia of the mesenchyme, and osteopsathyrosis. Osteogenisis imperfecta is still not completely understood, and while there have been advances in diagnosing the disease, Osteogenisis imperfecta is the result of mutations In the mild dominantly inherited form of OI (type I), † a non-functional allele for the alpha 1 (I) chain halves ollagen synthesis,† (Smith, 1995, 169) and is largely responsible for the inheritance. Single base mutations in the codon for glycine causes lethal (type II) OI by wrecking the formation of the collagen triple helix. Types III and IV are the â€Å"less dram- atic outcomes of similar glycine mutations in either the alpha 1 (I) or the alpha 2(I) The clinical signs can be caused from defective osteoblastic activity and defective mesenchymal collagen (embryonic connective tissue) and its derivatives, such as sclera, bones, and ligaments. The reticulum fails to differentiate into mature collagen or the collagen develops bnormally. This causes immature and coarse bone formation The signs and symptoms of OI vary greatly depending on the type. The most commonly used classification is the Type I is the mildest form of OI and is inherited as an autosomal dominant trait. The sclerae(middle coat of eyeball) is distinctly blue. Type I is broken down into IA and IB — the difference being whether dentinogenesis is present. IA has a life expectancy nearly the same as the general public. The physical activity is limited, and may appear to have no disability at all. The bones have a mottled or wormian appearance, forming small islands. Type II is lethal in utero or shortly there afterbirth. The survivors live from just a few hours to several months. The kayotypes of parents are usually normal. This type is broken down into three subgroups: IIA is characterized by a broad, crumpled femora and continuos rib beading, IIB by minimal to no rib fractures, and IIC by a thin femora and ribs with extensive fracturing. While in the uterus, there is poor fetal movement, low fetal weight, poor ossification of the fetal skeleton, hypoplastic lungs, the long bones of the upper and lower limbs are shortened or deformed, and the head is soft. Intrauterine fractures ccur, and parinatal death is usually from intracranial hemorrhage due to vessel fragility or respiratory distress from pulmonary hypoplasia. The bones and other tissues are extremely fragile, and massive injuries occur in utero or delivery. The ribs appear beaded or broken and the long Type III and IV are intermediate in severity between types I and II. Type III differs from I in its greater severity, and from IV in that it increases in severity with age. It can be inherited as either a autosomal recessive or dominant trait. The sclerae is only slightly bluish in infancy and white in adulthood, although the average life xpectancy is 25 years. Type IV is always dominant. With types III and IV multiple fractures from minor physical stress occurs leading to progressive and severe deformities. Kyphoscoliosis may cause respiratory impairment and predisposition to pulmonary infections. â€Å"Popcorn-like† deposits of mineral appear on the ends of long bones. The symptoms of OI tarde (types I, III and IV) can appear when the child begins to walk, and lessens with age. The tendency to fracture decreases and often disappears after puberty. Later in life, particularly during pregnancy and after menopause, more fractures occur. The bones are usually slender with short, thin cortices and trabeculae (fibers of framework), but can also be unusually thin. (Smith, 1983, 136) Narrow diaphysis of the long bones contributes to the fractures and bowing deformities. Scoliosis is common. The haversian cells are poorly developed. The bones lack minerals needed to form bone matrix. Epiphyseal fractures (end of the bone) results in deformities and stunted growth (dwarfism). Osteopenia, the decrease in bone mass, is symptomatic. Other signs of OI include hyperextensibility of the joints — double-jointedness– and abnormally thin, translucent skin. Discolored (blue-gray or yellow-brown) and malformed teeth which break easily and are cavity prone are found in patients Patients with OI have a triangular-shaped head and face, a bilaterally bulging skull, and prominent eyes with a wide distance between the temporal region. Hearing loss by the age of 30-40 is the result of the pressure on the auditory nerve because of the deformity of its canal in the skull, and the development of otosclerosis. Recurrent epistaxis (nosebleeds), bruising and edema (especially at the sight of fractures), difficulty tolerating high temperatures and mild hyperpyrexia are other symptoms. Thoracic deformities may impair chest expansion and the ability to effectively breath deeply and cough. (Loeb, 755) Patients are also more susceptible to infection. In assessing a patient data is needed about the genetic history and birth of the child, as well as a complete development assessment from birth. Vital signs are taken, and periods of increased heart and respiratory rate and elevated body temperature are note- worthy. Skin should be examined for color, elasticity, translucency, and signs of edema and bruising. A description of position and appearance of a child†s trunk and extremities and facial characteristics should be noted. The height of the child in terms of expected growth, signs of scoliosis or laxity of ligaments, and range of motion of the joints are all important. Sight and hearing should be tested since there are sensory problems associated with OI. The appearance of the sclerae and tympanic membranes and defects of primary teeth and gums are important. (Jackson, X-rays usually reveal a decrease in bone density. There is no consensus, however, as to whether the diagnosis can be made by microscopy of bone specimens. † (Isselbacher, 2112) DNA sequencing and incubating skin fiboblasts are two ways help diagnose OI. Prenatal ultrasonography is used to detect severely affected fetuses at about 16 weeks of pregnancy. Diagnosis of the lethal type II by ultrasound during the second trimester of pregnancy is by the identification of fractures of the long bones. Compression of the fetal head is seen by ultrasound probe, and low echogeneity of the cranium can be signs of skeletal dysplasia (faulty development of the tissues). Diagnosis is confirmed by postmortem examination including radiography and biochemical studies of cultivated fibroblasts from the fetus. (Berge, 321) Diagnosis by analyzing DNA sequencing can be carried out in chronic villa There is no known treatment of OI at this time. Treatment therefore is predominantly supportive and educational. Because of multiple fractures and bruising, it is important to diagnose this disease in order to prevent Treatment of fractures is often challenging because of abnormal bone structure and laxity of the ligaments. Splinting devices are used to stabilize the bones and to protect against additional fractures. Treatment aims to prevent deformities through use of traction and/or immobilization in order to aid in normal development and rehabilitation. Limb deformities and repeated fractures can e corrected by intramedullary rods — telescoping rods that elongate with growth. After surgical placement of the rods, extensive post- operative care is required because greater amounts of blood and fluid are lost. (Loeb, 755) It should be noted that the healing of fractures appear to be normal. (Isselbacher, 2112) Braces, immobilizing devices and Physical therapy is important in the treatment of OI. Bone fracture density in unfractured bone is decreased when compared with age-matched controls due to limited exercise, so it is essential to stay as active as possible. Physical therapy is also used for strengthening muscle and reventing disuse fractures with exercises with light Regular dental visits are necessary to monitor the ogists for vision and audiologits for hearing is also essential. Radiologists need to examine the structure and density of the bones, and an orthopedist is needed to set fractures and take care of other bone related problems. Counseling and emotional support is needed for both the patient and the family. It is important not to limit a child because of his/her disabilities, and to realize that many victims of this disease live successful lives. Debrah Morris, a successful business woman, and active fighter for isability rights and helping other patients of OI, says, â€Å"If I had the choice to be anyone in the world, I would be exactly who I am. The people I have met, the challenges I have faced, the opportunities that I have been presented — all are directly related to dealing with being a little person with brittle bones. (Kasper, 53) Many of the symptoms of OI can be confused with those of a battered child. X-rays are used to show evidence of old fractures and bone deformities to distinguish the difference. The Osteogenesis Imperfecta Foundation (OIF) has is a national support group that offers assistance to families in this osition and to increase public awareness. The OIF has a medical advisory council, chapters, support groups, regional meetings, biennial national conferences, and parent contacts to help families feeling alone and helpless. They also publish a newsletter, provide literature and videos about OI, and sponsors a fund to support research. Magnesium oxide can be administered to decrease the fracture rate, as well as hyperpyrexia and constipation associated with this condition. (Anderson, 1127) A high-protein, high-carbohydrate, high-vitamin diet is needed to promote healing. A growth hormone has also been dministered during childhood, and is shown to substantially increase growth. Treatment with bisphosphorates and related agents has been discussed to decrease bone loss, but no controlled studies have been done. Isselbacher, 2113) Since there is no cure for oseogenesis imperfecta, appropriate and properly timed rehabilitation intervention is of the utmost importance to ensure that the child is able to function to the best of his/her ability in society. A ten year study that was submitted in 1992 proves this. 25 of 115 children with severe OI were observed since birth or infancy at the National Institutes of Health, MD and the Skeletal Dysplasia Clinic at the Children†s National Medical Center in D. C. One was Type I, two Type II, nine Type III, and thirteen Type IV. They were classified by physical characteristics and functional Group A consisted of those who were severely dwarfed with large heads and marked bowing , contractures, and weakness of extremities. The highest functional skill expected was independent sitting. Group B was growth deficient, but with a normal sized head. Femoral bowing, scoliosis, and contractures of the hip flexors were characteristics. they were expected to stand and/or ambulate with braces. Group C were less growth deficient, and had good strength, but poor endurance. They had marked joint laxity and poorly aligned lower extremity joints, but Group A patients were the most severely involved. Most were basically sitters. The majority were totally dependent in their self care. Group B had the potential to become at least short-distance ambulators. These patients had acquired the ability to move to sitting, but had transitional moving problems, such as sitting to standing. ially independent in their self care. Group C had antigravity strength and 50% had good strength in their extremities. All were physically active and age-appropriately independent, but none were good long-distance walkers. Binder, 387-388) Progressive rehabilitation of these groups all included posture exercises and active range of motion and strengthing exercises. Group B had additional ROM and posture exercises, as well as Developmental exercises. Group C added coordination activities. Conclusion, â€Å"Management of patients with OI should address the child†s functional needs. Even though the degree of disability may be severe, management should not be limited to orthopedic procedures and bracing. Treatment lanning should be considered, but not totally based on genetic, anatomical, and biochemical abnormalities. Our ence suggests that clinical grouping based in part on functional potential can be useful in the appropriate management of children with OI. â€Å"(Binder, 390) Independence was stressed in this study, and even patients with limited sitting ability, upper extremity function can be improved to at least minimal independence in self-help skills. Potential ambulators should be helped because, although their ability might not progress past indoor ambulation, walking will make them more independent and may result in ncreased bone mineralization. Poor joint alignment, poor balance, and low endurance can all be improved with persistent, individualized physical and occupational therapy. For best results, therapy should be started as soon after birth as possible. Mainstreaming school aged children is also important. All of this together leads to â€Å"age-appropriate social development and markedly improved independence and quality of life in the majority of Osteogenesis imperfecta is the most common genetic disorder of the bone. It occurs in about 1 in 20,000 live births, and is equally prevalent in all races and both sexes. The Type I OI has a population frequency of about 1 in 30,000. Type II has a birth incidence of about 1 in 60,000. Types III and IV are less common and may be as high as 1 in 20,000. (Isselbacher, 2111) The occurrence of OI in families with no history or blue sclerae is about 1 in 3,000,000 births. (Smith, 1995, 171) The recurrence risks in families is estimated to be 6 to 10%, but is only estimated because most couples choose not to have any more children. 15 to 20% of patients with OI do not carry the gene for abnormal collagen, making many wonder if there is yet another genetic problem undiagnosed at this time.

Gps When cars were first invented, something like an electronic map that "pin-points" you on the globe and could find the shortest route for you to take to get to your destination in your car would be rediculous, and would only be dreamed about by the people with the greatest imaginations. But today, this concept is reality, in fact, is being used by millions of people around the world right now. It's all done with something called the Global Positioning System, (GPS). Today it is very simple to use this. In cars like Mercedes, Lincoln, BMW, and a few others, computers are installed directly into your car before you even buy it. But not everyone can afford cars like those, so you can buy computers to install into your car, these are also very expensive, but probably more preferred for those who just want the computer inside their car. But there's also another option, however, less convenient; laptops are being used by millions of people everyday, so with a CD-ROM drive and a GPS antenna, you can hook up your laptop to your car with an antenna and have the same results as the ones that come with cars.Artist Interpretation of GPS satellite, image cour...Just because we have these in our cars however, doesn't mean that we won't get lost, but it is more difficult to get lost, and it's definetly easier to find your way around if you do get lost.
