Stem Cell Research Advantages and Disadvantages

Stem Cell Research Advantages and Disadvantages JOSHUA REED ‘Do the potential benefits of stem cell research outweigh the risks and negative ethical implications associated with it?’ 1.  INTRODUCTION Stem cell research is currently one of the biggest fields in modern day science. It has numerous benefits currently, and it is only the beginning. The possibilities are endless, but there are many ethical implications associated with it, as well as many risks. Do the potential benefits outweigh these risks and negative ethical implications? 2. OVERVIEW OF STEM CELLS 2.1  DEFINITION OF STEM CELLS Stem cells are unspecialised cells which are able to become any type of cell in the body. They have the ability to divide and renew themselves for very long periods before they are specialised. The process in which they are changed into a specific type of cell is called differentiation. They can become cells of the heart, bones, muscles, brain, blood, skin, or any other type of cell. There are different types and sources of stem cells, but they all have the ability to develop into different types of cells. 2.2  TYPES OF STEM CELLS 2.2.1  EMBRYONIC STEM CELLS Embryonic stem cells are cells found in embryos during the blastocyst stage. They are obtained from the eggs of an infertile couple, that are fertilised in vitro, rather than in the woman’s body. 2.2.2  ADULT STEM CELLS Adult stem cells, also known as somatic stem cells, are found in certain tissue of fully developed humans. They can produce only certain types of cells. In the body they maintain and repair tissue. They can be found in bone marrow. They can also be found in the brain, skin, liver, skeletal muscle and in blood vessels, but in small amounts. 2.2.3  AMNIOTIC STEM CELLS Amniotic stem cells are found within the amniotic fluid. They are extremely active and can multiply without a food source. They have a limited number of cells into which they can form, but, unlike embryonic stem cells, they are unable to cause tumours. 2.2.4  INDUCED PLURIPOTENT STEMS CELLS These stem cells are formed by genetically programming adult skin cells to become stem cells. (i) 2.3 HARVESTING OF STEM CELLS There are different procedures followed to collect and harvest the different types of stem cells from their different sources. Embryonic stems cells are found in embryos. Specifically, they are obtained from eggs cells from an infertile couple, that have been fertilised in vitro, rather than within the woman’s body. The embryo is in the stage of blastocyst when they are able to produce embryonic stem cells. Usually about 30 stem cells can be taken from the blastocyst. These cells are then grown in laboratories by a process known as cell culture. The inner cell mass of the cells are removed and placed into a laboratory culture dish that contains a broth or nutrient medium, off which the stem cells will survive. The dish is often coated in mouse embryonic skin cells, known as a feeder layer, which allows the human stem cells to have a sticky surface to which they can attach. They also release nutrients into the medium within the culture dish. The dish is stored at a suitable temperature and humidity level which allows the cells to divide. The cells divide and fill the dish over several days. They are then removed and placed into several new culture dishes. This is repeated numerous times over several months and is known as subculturing. After several months, millions of stem cells can be formed from the first 30. They are then frozen in batches and sent to other laboratories for further experimentation. Another type of stem cell harvest procedure is the removal of peripheral blood stem cells. Typically, the donor is given large doses of chemotherapy, which causes a lot of white blood cells to die. The bone marrow is then forced to try and replace it. There is not enough space in your bones for all the extra blood, so the bone marrow forces large amounts of stem cells into the blood where they are able to mature. The donor, if they do not require chemotherapy, could be given a white blood cell growth factor known as G-CSF, which has the same effect. If the donor is the same person as the patient, they will use both methods to increase the harvest. When the stem cells are being harvested, the donor has an IV in both arms. The one extracts blood which contains the stem cells. The stem cells are extracted from the blood, and the blood is returned to the donor through the other IV. This can be used in the treatment of leukaemia. In a study involving around 38000 people, people who received treatment showed an increase survival rate from 48 to 63 percent one year after treatment. (ii) 2.4 HOW STEM CELLS WORK Stem cells have the ability to become any type of cell in the body. They can be used in treating several types of diseases. Stem cells work by being a source of new cells to replace defective, damaged or diseased cells. Stem cells are unspecialised cells, which form into specialised cells during a process called differentiation. Internal as well as external signals can cause stem cell differentiation. Internal signals come from within the nucleus, while external signals are caused by things such as contact with chemicals or other cells, as well as the presence of certain things in the environment. Stem cells in culture dishes are stimulated to differentiate into differentiated cells by changing the culture broth or medium, as well as the coating of the dish. Genes are also inserted. The differentiated cells can then be used as they are needed, or used for experimental purposes. 2.5 BENEFITS OF STEM CELLS 2.5.1  USE OF STEM CELLS AT PRESENT TRANSPLANTING BONE MARROW TO TREAT LEUKAEMIA HEALING BURNS WITH SKIN GRAFTS REPLACING DAMAGED CELLS AND TREATING DISEASES TO STUDY THE DEVELOPMENT OF ORGANISMS AND DISEASES TESTING NEW MEDICAL TREATMENTS MAKING INSULIN FOR DIABETICS TO INJECT 2.5.2  USE OF STEM CELLS IN THE FUTURE TO TREAT THINGS SUCH AS: DIABETES PARKINSONS LIVER FAILURE HEART DAMAGE CANCER BRAIN DAMAGE DEAFNESS BLINDNESS HAIRLOSS MISSING TEETH INFERTILITY 2.6 ETHICAL ISSUES SURROUNDING THE USE OF STEM CELLS There are several ethical issues surrounding the use of stem cells and their research. The biggest issue is the use of an embryo. Although the embryo is fertilised in vitro and come from willing couples, there are still issues regarding the debate of whether the embryo is human or not, and whether it has rights. Some people believe that human life begins at conception, or even before this, so the embryos are human and deserve rights and protection; while others believe that life begins when you are born, when your heart first beats, or a few months after development. Some groups see the use of embryos as a form of abortion. The debate depends on one’s own personal view as to whether the embryo is human or not. Another ethical issue many people have regards the use and creation of Human-Animal Chimeras. Chimeras are organisms that contain cells or tissues from multiple organisms. Some believe that it is ethically wrong to combine human and animal stem cells to form chimeras. They are separate organisms which should not be combined. Despite these issues, chimeras are important in forming actual therapeutic methods. Law prohibits the breeding of human-animal chimeras. The debate between preventing and reducing human suffering versus respecting the value of human life is another issue. Stem cells have the ability to cure numerous issues, and have the potential to prevent and treat several other things; but if embryonic stem cells are used, it can be seen as destroying one human life to save another. There are also several risks involved in stem cell research and use. It is relatively new, so the long term side effects of its use in humans is so far unknown, but they could be horrific. In tests done with rats, 20% that were injected with embryonic stem cells died of some form of tumour. (chem445stemcell, 2011) 3. MY PERSONAL VIEW Stem cell research is one of the most important fields of science in modern times. It is able to, and has the potential to cure numerous diseases, illnesses and problems found in humans. Despite this many people see it as unethical and full of risks. I believe that the potential benefits outweigh the risks and negative ethical implications associated with it. Stem cells are unspecialised cells which are able to become any type of cell in the body. They have many current uses, and they have the potential for numerous future uses. Scientists and doctors are able to do stem cell transplants from bone marrow to treat leukaemia. Thousands of patients over the globe have successfully received this treatment which has prolonged their lives. Stem cells are also able to heal burns through skin grafts, as well as replace damaged cells and treat diseases. Stem cells allow scientists to study the growth and development patterns of both organisms and diseases, as well as provide new ways of treating the diseases. Another important feature of stem cells is their use in the production of insulin for diabetics. The insulin produced is indistinguishable from human insulin. It is not only the current uses of stem cells that are important, but also the potential that they have. Scientists are experimenting and finding ways to use stem cells to cure diseases that were once seen as incurable, such as diabetes and Parkinson’s disease. They believe that they can find ways to cure liver failure, heart damage, cancer, brain damage, deafness, blindness, hair loss, missing teeth, and even infertility. Scientist believe that they will be able to use a patient’s own stem cells to grow new organs for transplant, which would be guaranteed to not be rejected. The possibilities are endless. Despite their potential, stem cells raise many ethical issues, and have many risks that surround them. The use of an embryo is questioned by many people. It is believed by many that human life begins at conception, or even before this. They believe that the use of an embryo is a form of abortion, or an exploitation of their human rights. Others believe that life only begins later in pregnancy, or at birth, so they disagree with this viewpoint. The embryos are donated willingly by couples, and are fertilised in vitro. Another issue that people have is that human tissue is combined with animal tissue to form chimeras. They are separate organisms and should not be combined to create new creatures. Additional, there is an ethical issue raised on the debate between preventing and reducing human suffering versus respecting the value of human life. Stem cells have the ability to cure numerous issues, and have the potential to prevent and treat several other things; but if embryonic stem cells are used, it can be seen as destroying one human life to save another. Some of the risks involved in stem cell research and use include that it is relatively new, so the long term side effects of its use in humans is so far unknown, but they could be horrific. In tests done with rats, 20% that were injected with embryonic stem cells died of some form of tumour. There are numerous ethical issues raised through stem cell research, but the potential that it has in curing and preventing diseases and issues in humans greatly outweighs them. Scientists must continue researching stem cells, and finding exciting ways in which they can be used. 4. EVALUATION AS TO WHAT INFLUENCED MY DECISION I visited numerous sources with different viewpoints to allow myself to make an informed decision as to where I stand regarding stem cell research. Regarding the use of embryonic stem cells, I believe that human life begins at conception, but the fact that the couples who donate the embryos are sterile and already have children, and that the embryos are fertilised in vitro, influenced me to believe that the use of embryonic stem cells is acceptable. In 2005, guidelines regarding the use of embryonic stem cells were laid. They urge scientists to work ethically, responsibly and sensitive in their work. They are not laws, yet they still lay the basis on which most laboratories work. There is more than one source of stem cells, so not all stem cell related topics are surrounded by numerous ethical issues. The numerous benefits and the potential that stem cells have also influenced my decision into supporting the study and research of stem cells. Stem cell research has the potential to save thousands of lives, and through research scientists will be able to discover and test the ways in which they can be used. 5. CONCLUSION Although there are many ethical issues surrounding the use of them cells, the potential benefits of their research greatly outweighs these issues. They have the potential to save the lives of those who thought they were unsaveable, as well as treat the untreatable. Through the right research and funding, the possibilities regarding stem cell research are endless. 6. BIBLIOGRAPHY AND REFERENCES REFERENCES Manda, D. A. (2014). Stem Cell Types.

Homosexuality

Many believe that higher Education leads to an increase in tolerance towards individual who are different. There are some empirical findings to support this premise; however the impact of higher education on acceptance of homosexuality has not been adequately explored. Gays and Lesbian in society face many negative attitudes. Homosexual expression in native Africa was also present and took a variety of forms. Anthropologists Stephen Murray and Will Roscoe reported that women in Lesotho engaged in socially sanctioned â€Å"long term, erotic relationships† called motsoalle.The first record of possible homosexual couple in history is commonly regarded as Khnumhotep and Niankhkhnum, an Egyptian male couple, who lived around 2400 BCE. The pair are portrayed in a nose-kissing position, the most intimate pose in Egyptian art, surrounded by what appear to be their heirs. In Homosexual and transgender individuals were also common among other pre-conquest civilizations in Latin America, such as the Aztecs, Mayans, Quechuas, Moches, Zapotecs, and the Tupinamba of Brazil In East Asia, same-sex love has been referred to since the earliest recorded history.Homosexuality in China, known as the passions of the cut peach and various other euphemisms has been recorded since approximately 600 BCE. Homosexuality was mentioned in many famous works of Chinese literature. Homosexuality in Japan, variously known as shudo or nanshoku has been documented for over one thousand years and was an integral part of Buddhist monastic life and the samurai tradition. This same-sex love culture gave rise to strong traditions of painting and literature documenting and celebrating such relationships.Similarly, in Thailand, Kathoey, or â€Å"ladyboys†, have been a feature of Thai society for many centuries, and Thai kings had male as well as female lovers. While Kathoey may encompass simple effeminacy or transvestism, it most commonly is treated in Thai culture as a third gender. They are generally accepted by society, and Thailand has never had legal prohibitions against homosexuality or homosexual behavior. South Asia, The Laws of Manu, the foundational work of Hindu law, mentions a â€Å"third sex†, members of which may engage in nontraditional gender expression and homosexual activities.Europe, In regard of male homosexuality such documents depict a world in which relationships with women and relationships with youths were the essential foundation of a normal man's love life. Same-sex relationships were a social institution variously constructed over time and from one city to another. Middle East, among some Middle Eastern Muslim cultures, egalitarian or age-structured homosexual practices were widespread and thinly veiled.The prevailing pattern of same-sex relationships in the temperate and sub-tropical zone stretching from Northern India to the Western Sahara is one in which the relationships were—and are—either gender-structured or age -structured or both. In recent years, egalitarian relationships modeled on the western pattern have become more frequent, though they remain rare. Same-sex intercourse officially carries the death penalty in several Muslim nations: Saudi Arabia, Iran, Mauritania, northern Nigeria, Sudan, and Yemen. Today, governments in the Middle East often ignore, deny the existence of, or criminalize homosexuality.Homosexuality is illegal in almost all Muslim countries. Iranian President Mahmoud Ahmadinejad, during his 2007 speech at Columbia University, asserted that there were no gay people in Iran. However, the probable reason is that they keep their sexuality a secret for fear of government sanction or rejection by their families. Israel is considered the most tolerant country in the Middle East and Asia to homosexuals, while the Israeli city Tel Aviv has been named â€Å"the gay capital of the Middle East,† and is considered one of the most gay friendly cities in the world.The annual Pride Parade in support of homosexuality takes place in Tel Aviv. In many societies of Melanesia, especially in Papua New Guinea, same-sex relationships were an integral part of the culture until the middle of the last century. Tel Aviv, â€Å"The gay capital of the Middle East†, Tel Aviv is one of the most popular destinations for LGBT tourists internationally, with a large LGBT community. American journalist David Kaufman has described the city as a place â€Å"packed with the kind of ‘we're here, we're queer’ vibe more typically found in Sydney and San Francisco.The city hosts its well-known pride parade, the biggest in Asia, attracting over 100,000 people yearly. In January 2008, Tel Aviv's municipality established the city's LGBT Community Center, providing all of the municipal and cultural services to the LGBT community under one roof. In December 2008, Tel Aviv began putting together a team of gay athletes for the 2009 World Out games in Copenhagen. In ad dition, Tel Aviv hosts an annual LGBT Film Festival. Lesbian, gay, bisexual, and transgender ( LGBT ) people in the Philippines have a dinstinctive culture but limited egal rights. Gays and lesbians are generally tolerated, if not accepted within Filipino society, but there is still widespread discrimination. The most visible member of the Filipino LGBT culture, the BAKLA, are a distinct group in the Philippines. According to the 2002 YOUNG ADULT FERTILITY and SEXUALITY SURVEY, 11% of sexuality active Filipinos between the ages of 15 and 24 have had sex with someone of the same sex. In the Philippines, the term gay is used in reference to any LGBT person.For Filipino gays, the tagalog phrase, pagladlad ng kapa ( â€Å" unfurling the cape† ) or more commonly just paglaladlad ( â€Å"unfurling or unveiling† ) refers to the coming-out process, tibo, t-bird and tomboy are degoratory terms for butch lesbians just as bakla is for effeminategay men. Some lesbians, both butch and femme, use the terms magic or shunggril to refer to themselves. Neutral s;ang terms for gay men include billy boy, badette, bading and paminta ( straight – action gay man). Although legislation supporting same-sex marriage in the Philippines has been proposed several times to the Philippine legislature, none has ever been passed.

Identifying Trainining Resources

UNIVERSITY OF BOTSWANA MASTER’S IN BUSINESS ADMINISTRATION MGT 745: HUMAN RESOURCE DEVELOPMENT TOPIC: IDENTIFYING TRAINING RESOURCES Introduction This paper purports to outline steps needed to identify resources for training. It will illustrate the advantages and disadvantages of using different types of training drawing examples from the authors’ workplace experience. Resource could be defined as follows, â€Å"a source of supply, support, or aid, esp. one that can be readily drawn upon when needed. â€Å"†¦The total means available to a company for increasing production or profit, including plant, labor, and raw material; assets. † http://dictionary. reference. com/browse/resources Resources can be defined as assets available and anticipated for operations. These include people (learners, facilitators/trainers/consultants), time, infrastructure, equipment, availability of training institutions, and availability of financial resources (money/funds). The ki nd of resources required depend on the type of training that is to be carried out. Hence the identification of training resources is a critical component of training/ learning effectiveness that can be manifested at the individual, team, and organisation level. It is therefore important to identify training resources as this allows training to make a difference that is noticeable; training with a practical value or utility to both employees and the organization. One key factor in employee motivation and retention is the opportunity to continue to grow and develop job and career enhancing skills. Employees need to be equipped to handle employee relations and responsibilities competently. Training in any organization needs resources to be executed or implemented effectively hence the need to draw up a budget that can be utilized. The major resource for training is financial, therefore the need for the department to have cost estimates for most of the training being investigated. For example at the Botswana Police Forensic Science Laboratory, every financial year when budget estimates are drawn for the lab, training is included in the budget. Courses that need immediate attention (as per the need of the lab or gap that exist) are listed together alongside estimated costs and length of the training. Institutions that offer the training, course content, length of training and costs are identified beforehand. This budget is then submitted to the training board of the Botswana Police Service for screening and approval. In the Department of Vocational Education and Training (DVET), short term training budget is decentralized to regional offices and the budget tends to be similar or vary slightly from the previous year whereas long term training budget is coordinated at head quarters. The implication is that short term training budget may not necessarily reconcile with any required training. The organization should also take cognizance of the fact that people learn in different ways, therefore the training has to match employee learning preferences which may help to speed up their training and reduce costs at the same time. Some considerations when identifying resources for training are: †¢ What areas need training to be conducted? i. e. identifying problem areas. †¢ Who needs training and in what area? †¢ How complex is the training that is needed? †¢ How much time do learners have to learn the new knowledge and skills? How much money is available to pay for the training, whether in-house or using a consultant? †¢ How capable are learners to undertake the training? †¢ What are learner's learning preferences and styles? For example, in DVET training for the junior officers (industrial class) is normally done in Setswana. †¢ What institutions are available for tailored or the required training? †¢ Could training be conducted in hous e, on the job, outsourcing or in external institutions? And which method could suite learners? And benefit the organisation in a valuable and practical manner. Types of Training Resources Internal Training The types of training, classified as internal, external or a hybrid of the two have a bearing on the types of resources needed to implement. Internal training can be mentoring, coaching, seminars, workshops or classroom based training e. g. at the department of Government Printing, there is internal classroom based training whereby employees are taught within the department. The training is based on the theory and technical knowledge that the staff needs in order to improve their performance and prepare them for further training. This type of training requires a trainer, classroom, equipment such as projectors, television and video technologies. After completion of this internal training, qualifying employees are then sent for further training abroad for a higher learning programme. In the case of Printing, where there are no local institutions that offer training within the country, the department relies on colleges/universities based in the United Kingdom. The Department of Land Board Services in the Ministry of Lands and Housing mostly provide classroom based training, for example, on introduction to computers. This training is conducted mainly for the industrial class workforce to equip them with basic skills for working and operating computers. The resources used for this type of training include computers, Information Technology officers who conduct the training and the members of staff. At DVET regional offices most short term training programs are externally sourced where it is assumed that specialized courses for specific needs and in addition staff are given liberty to select training courses and institutions but subject to approval by supervisors and funds permitting. Other general training courses such as customer services improvement courses are selected by human resources officers as part of staff development. However, public sector reforms are cascaded internally form senior management to junior officers in consultation/ facilitation with performance improvement coordinators and funds have to be availed as a matter of priority, at times combining facilitators, equipment and funds across departments within the same ministry. It is essential to note that internal training is not as costly as external training which is one of its major advantages, as it is cost effective. Many businesses choose to train employees in-house (type of internal training) can offer a number of advantages over external training providers. Internal training can be: †¢ tailored to specific business' needs †¢ scheduled for a time that suits business †¢ time effective – employees do not spend additional time or money traveling However, there are a number of disadvantages to note including some of the following: †¢ The possible tendency for employees not to take the training seriously especially if it is conducted by a core employee with low reputation within the organisation or has less to offer to other employees. Difficulties faced by the organisation to identify a suitable trainer or the necessary resources in-house / internally. †¢ The potential risk of passing or perpetuating existing inefficiencies or poor business practices For internal training to be effective, HR managers need to ensure they have the appropriate expertise and resources in -house. They will have to dedicate the necessary resources to training programmes. These resources could include management time, an experienced trainer, training or course materials, equipment such as PCs, telephones or machinery and space in which to carry out the training. To help expose and enhance the skills of internal trainer with less information to offer to learners, consideration should be given to send them on a train-the-trainer course to ensure their training methods and materials are up to date and effective. Alternatively, if there are no necessary skills in-house, HR managers could purchase off-the-shelf or tailor-made courses or choose whether to use an internal or external trainer to run the course. This should be supplemented by appropriate e-learning courses and investing in internal training support databses. There are tailor-made courses covering a wide range of topics, one should choose a course that meets organizational and employees needs. They can be targeted, confidential and cost a fraction of the price of sending each employee on an external scheme. ON- The- Job Training (OJT) Under internal training there is also On-the-job training (OJT): Having a person learns a job by actually doing the job. OJT methods Coaching/ understudy For example at the BPS Forensic lab, when new employees start work (newly employed), they first undergo intensive in-house training before they can be released to work independently. At first they circulate in all the sections of the lab to get an overview of what each section does, then after which they are sent to the relevant sections they were employed to join. This is where they are taken through intensive coaching on the tests that are carried out at that particular section. Trainees are taught the theory behind the tests done, shown how to do the actual tests, then do the tests themselves under the supervision of the facilitator (usually an experienced member of the section). At the end a supervisor assesses them both theoretically and practically. When they satisfy the required standard of performance, they are then allowed to work independently. At DVET coaching of new staff does not follow any uniform structure. The new staff members will be coached on the requirements of the job and will then conditions will require older staff in the field to assign tasks coach and supervise the new staff work. At DVET our coaching has advantage of making new staff get to know how to do work quickly, but has disadvantage of not being documented hence may not necessarily consistently follow any set guidelines. Job rotation Job rotation consists of moving a trainee from department to department to broaden his or her experience and identify strong and weak points, the method is inexpensive and provides an organisation with immediate feed back. In the Department of Culture and Youth, Performing arts Unit job rotation is widely used mainly because of lack of staff. An Arts Festival organizer and manager could be assigned perform information and systems analysis activities/ funds allocation / research and documentation activities. This has worked for the department through the years as the organisation is sure of continuity of its programmes despite the loss of any officer in certain specialty areas. One officer who was originally a Performing Arts research and documentation officer ended up being a systems analysis officer. The officer realized that he did not really enjoy his line of specialty hence could easily shift from one specialty to the next for the benefit of the organisation. Seminars and Workshops At the BPS Forensic Lab, some seminars/workshops are conducted for all the employees on certain subjects, e. g. Occupation Health and Safety workshops. Employees gather at a venue and a consultant/facilitator is sourced to deliver on the subject. However, for other workshops one or two employees are chosen to attend on behalf of the lab (especially for those that involve a wide range of participants from different labs/departments and charge expensive attendance fees). After the seminar/workshops the rep(s) share what they have learnt with other employees of the Forensic lab through presentations. They also produce a report which is sent to the Police HR department and a copy left with the Director, Forensic Science Services. At DVET seminar and workshops are the major methods used to enhance skills of staff for short term training. External Training External training has to do more with taking employees to an institution or a place outside the parameters of the working environment. Unlike internal training, this requires more and extensive preparation. It is also capital intensive as more money is needed to pay for accommodation, food, learning materials and other costs associated with training. The HR unit has to first identify appropriate institutions where they can send their employees and his takes time as one has to research on the place before making any decisions. After completing the research a database of these learning places is created so as to have readily available information on where to get what kind of training and at what cost. In identifying these training institutions, the HR unit can send out tenders/quotations to companies. In other cases, institutions themselves send out brochures o r call the organizations and advertise themselves. For example, BNPC and BOBS email their training programmes for the year to our department on matters relating to productivity and quality management. They also advertise on the newspapers. At DVET regional offices every year a compiled list of staff needs are sent to HR officers at head office who in turn prioritize and select officers from training. However, due concerns on transparency of the wholly exercise a training committee is about to start working on staff training, though its guidelines are yet to be finalized. Attachment An example of external training which may not be as costly is sending employees for attachments to other organizations that offer similar services or have advanced technology that you need to learn about. As some people learn better in a practical environment, so sending them for an attachment to an organization that offers the same or similar services will be vital. This kind of training is very cost effective because sometimes if it is done locally, not much money is spent. Example: The department of GPPS wanted to buy new equipment, an image-setter which we found was available at a local private printing house. One officer from the unit that uses the equipment was sent to that company for three months to learn how to operate the equipment. There was no money required as the company offered to help. The training was effective as the employees now assists in operating the equipment and was also able to teach colleagues in the same unit. Example of External training at the BPS Forensic Lab It comes in the following forms a) Attachment of Scientists to labs outside Botswana who have advanced technologies and expertise that ours. The scientists are sent there to learn how to do certain tests or how to operate certain machinery. When they come back, they teach other members of the section, make presentations to the whole lab, and produce a report. b) Short courses (e. g. o obtain certificates on certain operations), Masters’s Degrees in Forensic Science as well as PHD’s in Forensic Science. These courses are offered outside Botswana (no local institution offers courses on Forensics at present), and in many instances people are sent to the UK or the USA. The skills that they acquire in their training are also shared by teaching others what they learnt and also come up wi th better ways of doing things. They also submit reports and make presentations. Apprenticeship training It is a structured process by which people become skilled workers through a combination of classroom instruction and on-the-job training. At the University of Botswana this is done mainly by the engineering department. Students spend time in the classroom learning there after take a semester or 2 working on attachment with DeBeers or any engineering company. This method is advantageous because it links work experience with the learning experience hence preparing a learner to be ready for the workplace. Furthermore, to cut cost in external resource training  an HR Manager should plan ahead to cut costs. That way the manager could be able to send or book a course for a larger group of people to get discounts. Or could send one person on a training course and ask them to teach others in the business. Or take up free offers and cheap training from providers of new machinery and systems. How to identify External Resources Important Steps for identifying external resources drawn from the authors’ various workplaces, 1) List all institutes that offer training and information about them that is location, contacts, type of workshops, Etc. There are many institutes offering training courses, workshops and programs. With the advent of the Internet, many sites also offer free or chargeable online training. ) List key training areas offered by each institute 3) Relate each training area to employees’ needs, competencies and capabilities identified earlier. 4) List web sites that offer free or chargeable online training and maintain up to date information. 5) Correspond with institutes to keep the Department up to date. The advantages of using training providers are: †¢ they are sp ecialists †¢ they can bring you up to date on current best practice and new ideas †¢ employees may interact with counterparts in other companies †¢ employees may learn better away from their usual work environment The disadvantages: it is difficult to know the ability and subject knowledge of the trainer †¢ putting an entire team through training at the same time can disrupt your business †¢ they are more costly than delivering internally †¢ the training may not be specific to your particular business †¢ Not up to date lists of institutions will lead to loss of time when training is required. †¢ Limited knowledge in what is available in terms of training may lead to misconceptions about what the staff may require in terms of their training. E-learning and distance learning courses: There are different types of distance learning methods including correspondence courses and e-learning courses. Some courses may be completed online while others might incorporate study books, CD-ROMs or audio and video tapes backed up by student tutorials and seminars. Distance education and E – learning are therefore advantageous because they †¢ allow employees to complete training while remaining in employment †¢ can be completed at a time to suit the business and employees †¢ are cheaper than externally provided courses are available for a wide range of business topics †¢ Offer recognized qualifications from entry level diplomas and certificates to post-graduate degrees. Training via the Internet: Using the internet or proprietary internal intranets to facilitate computer-based training. University of Botswana has recently established an E-Learning e. g. WEBCT, programme whereby students and staff could learn th rough internet/ intranet. This type of computer based learning carry the Advantages of reduced learning time, cost-effectiveness and consistency in instruction material, methods and presentation. The University also has distance programmes offering Degree in business studies and Diploma in Primary Teaching Education. Radio/ Teletraining: A trainer in a central location teaches groups of employees at remote/ or different locations via TV hookups. This is mainly used by Ministry of Education especially through radio. As a teacher one experience radio lessons whereby both students are taught through radio and instructions are given to the teacher as to how or what to provide to the students. Videoconferencing: Interactively training employees who are geographically separated from each other—or from the trainer—via a combination of audio and visual equipment. One recalls a situation whereby, students who studied Music at University of Natal – Petermarisburg campus from 1999 – 2000 experienced video conferencing. At the time the University, currently known as Univesrsity of Kwazulu Natal, offered Music Degree at the Durban Campus, which then disadvantaged students in petermarisburg. Therefore the University devised the video conferencing to train Petermarisburg students in music courses from Durban campus. While lesson were on process in Durban Petermarisburg students also experienced an interactive and learning process of the same class through video conferencing. Conclusion While internal training is important and can be invaluable in some areas of development, the external training process can add interest, give a greater breadth of experience and working practices, and equally important is the freedom to be able to choose a course and a style of learning that is suitable for each individual, rather than the department or team as a whole. Each individual member of the workforce will have different needs, both in terms of the type of training they require, the level of training and of course the time needed to train. Pitman Training for example, offers flexible learning, which means companies can guarantee each of their employees is meeting their individual achievements and targets, while fitting in their study at a time which suits them. Training can be done at their convenience, without having to sacrifice time at work and also without upsetting that all important work-life balance. Possibly the biggest benefit of drawing on the expertise of an external trainer such as Pitman Training, is the attraction of gaining a nationally recognized certification – providing your staff with confidence that they're receiving quality training, and your company the knowledge that it has quality trained staff All types of training resources seem to carry advantages and disadvantages; this study recommends that an organisation should choose training resources according to its learner’s needs and capabilities. Organizations could outsource trainers who would make the learning meaningful; skills transfer easy and motivate the learner. Outsourcing has the advantage of quickly addressing specific needs, and easier to coordinate but has the disadvantage of being relatively expensive. Organizations could also broaden employee’s skills through on job training and in house seminars, workshops as well as forums and short courses to save on time and cost since time is an essential tool for effective production and success of the organisation. It is advised that organizations should purchase training resources such as laptops, projectors, mobile screen, flip charts, markers, and conference room etc for in house training to be efficient and effective and cost effective. Therefore this paper concludes that there is no best method of training resources but it mostly relies on the needs and capabilities of an organisation. Hence an organisation should choose what is best for it and also consider balancing all the methods provided in this paper.

networking Essay example - 2592 Words

INTRODUCTION TO NETWORKING Abstract One problem seen with people today is that they are unaware what of a computer network is. They might have heard of a computer network, but they are clueless as to how it works or why it works. People have basic questions that need to be answered. The goal of this paper is to give basic network information that will hopefully answer those questions. To give people an understanding about computer networks there are several areas that we must discuss. Definitions of some network nomenclature will be provided. Many people may have heard or seen these words, but never knew what they meant. Another part that is important is†¦show more content†¦Demand for the services of these large computers increased which meant upgrades had to be made frequently to keep the processing power ahead of the user need. These systems, called Mainframes, had been designed to provide computing power, but did not have the flexibility to satisfy the growing set of applications.† (Jones, 2001, Pers onal Computers History and Development) Also, in the 1960s the military used networks to communicate to one another. It worked like the time-sharing network. They needed this network to communicate between cities, bases, and states. â€Å"There was also a concern about a nuclear war. If there was a nuclear war how would people communicate? There needed to be a network that would be able to work after a nuclear strike. They came up with a quot;hot potato network. Basically the information would be tossed like a hot potato from user to user until it reached its destination. The actual route it took was not important. This meant that if big parts of the network were destroyed the message would try another route. It becomes apparent this was not as efficient compared to the traditional telephone system.† (Jones, 2001, Personal Computers History and Development) During the 1970s and 1980s, networking was continuously being upgraded. Businesses, schools, and the government needed faster networking capabilities to handle all the people that were using the basic quot;time-sharingquot; network. â€Å"In 1975, the first personalShow MoreRelatedNetworking1200 Words   |  5 Pages1.
