The current learning methods and advantages of ICT in subject-based Essay

The current learning methods and advantages of ICT in subject-based classes - Essay Example Students themselves find it convenient to use ICT to learn rather than traditionally attending lessons. Moreover, developments in ICT like the virtual field trip are also highly appreciated and are enhancing the learning of students in subject based lessons. Information Technology is a revolution of contemporary times. It is a concept, a term which has changed the way this world functions and integrates itself into one unit. Defining information technology is a complex task because it encompasses so many things and its scope is so huge that it is difficult to simplify and state. If we try to define information technology in a very comprehensive and compact way, we can say that it is concerned with everything regarding computer-based information systems, especially with the software and hardware that are used to help them function. The software applications and computer hardware that are used to support all these computer systems form a major part of this study. Moreover, whether we think of the study, their design, their further development, the implementation and use, them being support systems in many fields or their effective management, it all lies in the term information technology. Information is the most valuable intangible asset that can be possessed by an individual, a team or a big corporation. Information technology is that revolution in science which allows for this information to be safely kept by these people. It deals and places high importance on the efficient and effective use of this information through helping its conversion, proper storage, first-class protection, relevant processing depending on the type of information, its transmittal to the correct person and timely retrieval. It does all these steps ensuring and making the informations security its top priority. Our research paper has its topic "Advantages of ICT". ICT stands for Information and Communications Technology.

Genetically Modified Food And Crops Biology Essay

Genetically Modified Food And Crops Biology Essay Genetic modification of crops and food stuffs is one of the major controversial debates in the world. There have been doubts on the safety of genetically modified foods especially in the area of human health and environmental degradation. Many people have fears that their health could experience unforeseeable effects by altering the genetic content of a plant. Genetic modification might have resulted to the growing of pesticide and herbicide tolerant plants but the new technology has dangerous effects on human health and the environment. Genetic modification of crops has led to reduced effectiveness of herbicides and pesticides, transfer of genes to species that are not targeted, and has caused harm to important organisms. It has also caused allergies to most people in different parts of the world and raised economic concerns. Though the supporters of the new technology argue that it has led to increased crop yields and alleviation of nutrition deficiencies, genetic modification has obviously caused more harm than good. Introduction Genetically modified foods have been used widely in the 21st century and have splashed in the media lately. Public awareness groups and European environmental agencies have been frequently protesting against genetically modified foods and crops for years, and the latest controversial studies regarding the effects of GM corn pollen on sovereign butterfly caterpillars have prompted the issue of genetic engineering hence bringing it to the front position of public awareness in the United States. As a result, the United States Food and Drug Administration (FDA) has held three public meetings in Washington D.C., Oakland, California, and Chicago to importune opinions by the public and start the procedure of establishing an effective regulatory method for government sanction of genetically modified foods. GM foods have resulted to adverse effects especially in regard to environmental hazard, human health risk, and economic concerns. In respect to this, the government should discourage the g rowing of genetically modified crops and establish policies that ensure GM foods and crops are labelled (Institute of Medicine U.S. Committee on Identifying and Assessing Unintended Effects of Genetically Engineered Foods on Human Health 23) Literature Review Genetically modified foods and crops refer to plants scientifically created for animal or human consumption using the most recent molecular biology techniques. Basically, these crops are modified in the laboratory to improve nutritional content. Traditionally, enhancement of plants nutritional content was achieved through breeding but such conventional crop breeding methods proved to be time consuming and not quite reliable in terms of accuracy (Ferry and Gatehouse 59). On the other hand, genetic engineering creates crops that rapidly exhibit the exact desired traits with great accuracy. For instance, its possible for a plant geneticist to cut off a drought tolerance gene and insert it to a different plant. Consequently, the genetically-modified plant will become drought tolerant after acquiring the essential gene. Surprisingly, its also possible to transfer non-plant organisms besides the plant-to-plant gene transfer. The Bt or Bacillus thuringiensis, genes transfer to crops such as corn is a good example of non-plant organisms genes transfer. Bt is a bacterium that occurs naturally and produces insect larvae lethal protein crystals. Moreover, the Bt protein genes are transferred into corn, making it possible for the corn to generate pesticides of its own for instance the European corn borer (Ferry and Gatehouse 60). Pesticide resistant rape plant is on of the genetically modified crops. Scientific researchers have introduced a foreign gene to the rape plant which gives the plant the capability to resist certain pesticides. Consequently, a farmer is able to safely spray his genetically engineered rape plants with pesticides and destroying harmful pests without killing the crops. However, there is a possibility that the introduced genes may be transferred to the pests hence making them resistant to the pesticide as well and the plant spray becomes ineffective (Institute of Medicine U.S. Committee o n Identifying and Assessing Unintended Effects of Genetically Engineered Foods on Human Health 24). In this context, its possible for rape plants to pollinate the navew weed which occurs in rape crop fields. The navew weed acquires resistance to pesticides after gaining the introduced genes from the rape plants. Another example of GM crop is the golden rice which has been genetically engineered to increase its nutrition content by introducing an extra amount of vitamin A. More precisely, golden rice contains the beta-carotene element which is converted into vitamin A by the human body. Beta-carotene is the element responsible for the orange colour found in carrots and the golden colour in this particular rice. However, for the rice to produce beta-carotene, two genes from daffodils and one from bacterium must be implanted (Ferry Gatehouse 60). Methodology The study on genetically-modified crops/foods is very important and adequate information is required to determine the possible downfalls of the new technology. Books by reputable authors will be used to gather sufficient information on the topic. Additionally, relevant articles touching on the current progress of the new technology will also be used to realize recent discoveries. Discussion Natural breeding techniques have been used safely for the past numerous thousands of years. On the contrary, Genetically modified plant technology abrogates reproductive processes that occur naturally, selection takes place at the single cell stage, the process is extremely mutagenic and more often than not breaches genera barriers even after being in use for about ten years. In spite of these differences, the assessment on the safety of genetically modified crops is often based on the substantial equivalence idea such that In case a new crop or food is found to be considerably equivalent in nutritional and composition characteristics to an already existing crop/food, it may be regarded as harmless as the conventional food/crop (Gordon 144). Nevertheless, a number of animal studies designate serious health risks linked to GM crop/food consumption including dysregulation of genes related to synthesis of cholesterol, accelerated aging, and protein formation. Religious organizations, Environmental activists, professional organizations, public interest groups, and other government and scientist officials have raised their concerns about genetically modified foods/crops. Agribusiness pursues profits showing minimal concern for possible environmental and human health hazards as well as economic concerns. Environmental hazards Reduced pesticide and insecticide effectiveness; most insects and pests are likely to develop resistance to Bt just like some mosquito species have developed resistance to DDT pesticide which has already been banned from the market. In addition, there is a possibility that insects and pests may develop resistance to pesticides produced by genetically-modified crops. This will eventually lead to destruction of large amounts of crops both in the field and in the store. Harm to other organisms: In reference to a laboratory study published last year, 2009, pollen from Bacillus thuringiensis corn caused a high rate of deaths in monarch butterfly caterpillars. These caterpillars do not consume corn but milkweed plants, but there is a possibility that pollen from Bt may be blown by wind onto the neighbouring milkweed field and hence the caterpillars will consume them and die. Even though the study wasnt conducted on natural field, the results are likely to support this viewpoint. Unfortunately, Bacillus thuringiensis toxins indiscriminately kill many insect larvae species, its impossible to produce a Bt toxin that only kills pests that are crop-damaging and remain safe to other insects (Heller 227). However, this study is under re-examination by the United States Environmental Protection Agency (EPA), USDA, and other non-governmental research agencies. Interestingly enough, data from recent studies suggests that data from the original study may not have been accurate. Currently, the debate on the results of these studies is still on-going, and the possible risk of harm to organisms that are not targets will need further evaluation (Institute of Medicine U.S. Committee on Identifying and Assessing Unintended Effects of Genetically Engineered Foods on Human Health 50). Gene transfer to non-target species: Another major concern is that crops modified for herbicide tolerance and field weeds might cross-breed, hence leading to the transfer of the resistance genes from plant crops into the adjacent weeds. The resulting weeds will be super and are more likely to become tolerant to the herbicide as well. Other new genes may cross into non-engineered plant crops adjacent to GM crops. The interbreeding possibility is shown by the farmers defence against labelling of GM foods. A good example is the Monsanto case, where the company has filed exclusive rights intrusion lawsuits against GM crops farmers (Gordon 144). The only possible ways through which GM crop farmers can resolve these environmental hazards is by creating male sterile plants. This will ensure that non-target species do not receive new genes from GM crops. On the other hand, the farmers can modify the GM crops in a way that the pollen doesnt consist of the introduced genes. Consequently, there would be no possibility of cross-pollination and harmless insects would survive after consuming pollen from GM crops (Ferry and Gatehouse 121). Another probable solution will be creating buffer zones around GM crop fields. For instance, non-GM corn can be cultivated to surround a Bt. GM corn field, although the non-GM corn should not be harvested. Harmless or beneficial insects would take refuge in the non-GM corn, and pests can be allowed to wipe out the non-GM corn field without developing resistance to Bacillus thuringiensis pesticides. The wind-blown pollen will not cross over to weeds or other crops since the buffer zone wouldnt let it. Nonetheless, this planting method maybe unpractical if large buffer zone acreage is required (Ferry and Gatehouse 150). Human health risks Allergenicity: Allergy emergence is one of the most common human health threat posed by genetically modified foods (Puszta 2001). In the event of genetic modification, a protein with allergic effects could be transferred to a different crop. Additionally, allergic effects could be exacerbated through the biotechnology process, and new proteins that become allergens could be created in GM crops. For example, lots of children and grown-ups in Europe and the United States have developed allergies that are life-threatening to foods such as peanuts. There is likelihood that plant may create a new allergen or cause an allergic reaction in susceptible individuals. A good example is the Brazil nut-to-beans genes transfer proposal that was rejected because of its possible allergic reactions. However, GM foods may require extensive testing in order to avoid possible consumer harm through allergies (Gordon 144). Unknown effects on human health: Transferring or introducing alien genes into food crops may result to unexpected negative effects on human health. An article recently published in Lancet scrutinized the effects of genetically-modified potatoes on the digestive system in rats. This study argued that there were significant differences in the intestines of GM potato fed rats and those of rats fed naturally cultivated potatoes. Until now critics argue that this results, like the monarch butterfly data, is faulty and doesnt hold up to scientific examination. Furthermore, the gene transferred into the potatoes was lectin, a snowdrop flower already known to be poisonous to mammals. The research scientists who produced this variety of potato decided to use lectin gene just to test the methodology, because these potatoes were not intended for animal or human consumption (Gordon 143). Economic concerns Introducing GM foods to market is a costly and lengthy process, and certainly agri-biotech companies aspire to ensure a cost-effective return on their investment. Several new plant genetic-modification technologies and GM crops/foods have been unapproved and patent breach is a great concern of agribusiness. Yet consumer advocates are concerned that patenting the new plant varieties is likely to raise seed prices so high such that small-scale farmers and third world nations will be unable to come up with the money for GM crop seeds, thus increasing the gap between the rich and the poor. People are hoping that in a compassionate gesture, more non-profits and companies will offer their products at a fair cost to poor countries (Ferry and Gatehouse 172). Enforcement of patent may turn-out to be difficult, as the farmers contention that they unwillingly grew Monsanto-modified strains when their crop plants were cross-pollinated. Introducing a suicide gene into GM plants would be an excell ent way of contesting possible patent breach. These crop plants would be feasible for one planting season and would produce seeds that dont germinate since they will be sterile. Farmers would have to purchase a fresh supply of planting seeds yearly. However, this would strain farmers financially especially in third world nations where they cannot afford to purchase seeds every year (Ferry and Gatehouse 173). In contrast, genetic-modified crops have been known to exhibit pest resistance. Insect pests can cause serious crop destruction and loss, hence resulting in distressing financial loss for farmers and prolonged starvation in third world countries. Most farmers buy and use many tons of insecticides and pesticides yearly. Moreover, pesticides can cause potential health hazards and excessive use can contaminate water sources and the environment. Cultivation of genetically-modified crops can eliminate the need for pesticides hence minimizing on costs. However, this method may harm pests that are important for crop growth processes such as pollination. Apart from this, genetically-modified plant crops exhibit herbicide tolerance. Considering that physical weed removal may not be cost-effective for certain crops, farmers are forced to spray large quantities of herbicides to destroy weeds which is expensive and time-consuming. Cultivating plant crops that are genetically-modified to resist a powerful herbicide might help in preventing environmental contamination by minimizing on the herbicides used. Despite the risks involved in genetic-modification of crops/foods, the biotechnology industry continues to claim that genetically-engineered crops can feed the entire world by producing higher crop yields. Nutrition Malnutrition has been reported to be a major problem in developing countries where poor people depend on crops such as rice as their key staple food. Nevertheless, such foods do not contain sufficient amounts of nutrients necessary to prevent malnutrition. If such crops were to be genetically-modified to contain extra minerals and vitamins, deficiencies of nutrients could be alleviated. However, an up to date report by Union of Concerned Scientists analyzed twelve academic studies and indicated that GM foods form a small percentage of the worlds produced food. Bt. corn proved to be the only exception since a high yield in GM corn was reported. As a matter of fact, the report further sated that the significant increase in crop yields was as a result of improvements in trad itional breeding (Institute of Medicine (U.S.). Committee on Identifying and Assessing Unintended Effects of Genetically Engineered Foods on Human Health 101). Conclusion Genetically-modified foods/crops may be the potential solution to many of global malnutrition and hunger problems, and to aid in preserving and protecting the environment by minimizing dependence upon chemical herbicides and pesticides, and increasing crop yield. Nevertheless, there are several challenges ahead for farmers and national governments, particularly in the areas of, international policy, regulation, safety testing, and GM food labelling. Needless to say, genetic-modification is the inevitable future wave and that the society may not afford to ignore this technology though it has several dangers which outweigh its benefits to both the consumer and the farmer. However, members of the society must carry on with caution to avoid causing environmental hazards and unintentional harm to human health as a result of enthusiasm for this new technology. Recommendations Considering that GM foods pose serious health risks in the areas of allergy, reproductive health, metabolic, and immune function, farmers ought to adopt the precautionary principle. This principle is the key European Union environmental regulatory tool and health policy which has formed numerous international agreements. The precautionary approach is to be applied by nations in accordance with their capabilities in protecting the environment. In case of serious threats of irreversible damage, presence of limited scientific certainty should not be utilized as a reason for postponing gainful measures to prevent degradation of the environment. Bearing the precautionary principle in mind, physicians should educate the public, patients, and the medical community to avoid genetically-modified foods if possible and offer educational materials on health risks arising from GM foods. Moreover, the scientific and medical community should gather information related to health effects resulting fr om the consumption of GM foods. This may include conducting research on safe and effective methods of considering GM foods effects on human health. Lastly, implementing long term labelling and safety testing methods of genetically-modified foods/crops will be an important factor.

Global village Essay

America was a time of challenging authority and established conventions. It was into this era that a Professor of Media studies at Toronto University rose to media personality status. Marshall Mcluhan is famous for introducing society to catchy aphorisms such as â€Å"the medium is the message†. Although his theories have always been contested, they were popular at the time and are currently enjoying a revival. One such theory is his vision of the â€Å"Global Village† which I will discuss in this essay. To understand the term, a comprehension of some of his other ideas is necessary. Mcluhan was influenced by Harold Adams Innis who suggested that each medium of communication had a time â€Å"bias† which affected the stability of society. In short, he saw that â€Å"time biased† media such as stone carving would endure time and lead to a stable society. â€Å"Space biased† media, such as papyrus, could easily be revised and lead to an unstable culture (Meyrowitz 1985:17). Mcluhan went beyond this to suggest that different media have â€Å"sensory bias† (Postman went beyond this to argue that the medium contains an â€Å"ideological bias†). Mcluhan saw each new media invention as an extension of some human faculty. In The Medium is the Massage he notes, â€Å"All new media are extensions of some human faculty† (Mcluhan and Fiore 1967:26). The book illustrates some examples; the wheel of the foot, the book of the eye, clothing of the skin and electronic circuitry of the central nervous system. In terms of the â€Å"global village† the last extension is the most important. He saw us as breaking our ties with a local society and, through our new electronic extensions, connecting globally to a new world of total involvement. â€Å"We now live in a Global Village†¦a simultaneous happening† (Mcluhan & Fiore 1967:63). He refers to the village as a global community, existing with a level of connection associated with small rural settlings. We can see evidence for this in terms of what is sometimes termed an â€Å"always on† culture. News travels instantaneously across the globe, 1 in 6 people own a mobile phone (Guardian 2002) and the Internet smashes old barriers of communication. However, the Internet was in its infancy when Mcluhan used the term, which was first used in response to radio. There is some debate over the origin of the term â€Å"global village†. Eric Mcluhan writes that James Joyce reffered to a similar phrase, as did Wyndham Lewis. His opinion is that his father was probably already developing the concept and found it referenced in Lewis’ work afterwards. Mcluhan’s view of the â€Å"Global Village† was positive. He saw it championing greater social involvement and wrote, â€Å"In an electronic information environment, minority groups can no longer be ignored† This is a technological determinist attitude as it holds the medium as the single key to their involvement. Mcluhan also notes, â€Å"there is absolutely no inevitability as long as there is a willingness to contemplate what is happening† (Mcluhan and Fiore 1967:25). This is rather at odds with some of Mcluhan’s other material. He often makes poetically powerful statements about our helplessness in the face of technology (â€Å"All media work us over completely† (Mcluhan & Fiore 1967:26)). Digital TV offers increasing interactivity with Internet functions such as e-mail and online banking available next to greater entertainment choices. It is being put to an alternative use in sheltered housing by allowing residents in difficulty to contact the manager; an example of how new technology is including minority groups. However, with the advent of digital TV the Government has come under pressure to sell the broadcasting spectrum that analogue occupies and is planning to do so before 2010. The effects of this look set to create a greater divide than the one it healed. 50% of homes currently have digital TV but a third of homes are unable to receive digital TV at all. A report by the Department of Trade and Industry found that 6% of the population are likely to object to the switch-off based on the cost of upgrading and the belief that we watch too much TV (The Observer, 2004). If the analogue signal were to be switched off, those who couldn’t (or wouldn’t) receive digital TV would have no access to TV. The gap between rich and poor would accelerate and a greater social divide would exist. Technological Determinists refer to a â€Å"technological revolution† and since the invention of this term there has been concern for those left outside. The issue is more complex than Mcluhan presents it and subject to factors beyond that of just the medium. In Mcluhan’s time the Internet was far from the widespread facility it is today. He died in 1980, but only 5 years later the system to which the phrase â€Å"online community† is most pertinent was operational. Internet forums allow a number of people across the globe to converse in real time. The Internet seems to provide the most convincing argument for the â€Å"global village†. With broadband most actions are instant, allowing the user to converse, transfer money, view information and order products regardless of geography. Mcluhan’s idea of electronic circuitry extending the nervous system is easier to comprehend when you consider someone sitting down at a computer. The physical action of typing becomes the cause, but the effect is realised in an electronic global network. Meyrowitz notes how â€Å"At one time, parents had the ability to discipline a child by sending the child to his or her room-a form of ex-communication from social interaction† (Meyrowitz 1985:Preface). This is no longer the case. The Internet offers the possibility of extending our central nervous system across the globe. It is intrinsic in today’s society and much has been written over its social effects. Wellman and Gulia remark, â€Å"those on either side of this debate assert that the Internet will create either wonderful new forms of community or will destroy communication altogether† (Wellman: â€Å"The Networked Community†). The reality is unlikely to be as clear as this (although Mcluhan’s â€Å"global village† would suggest that it is). Meyrowitz has argued that new media blur the boundaries between public and private behaviour (Meyrowitz 1985:93-114). The same headline in a newspaper and read by a newsreader are two different messages. Print media does not invite the same depth of character analysis that TV does. The public broadcast begins to merge a private situation and invites a personal reading of the presenter. The personal homepage is an explicit example of the blurring between public and private boundaries. People from all walks of life are making available to the connected world their presentation of themselves. Cheung notes how it can be emancipatory as it allows you to rehearse your presentation (Cheung 2000). Unlike face-to-face communication you can refine your presentation until you are content. Mcluhan envisaged the â€Å"global village† as creating a greater level of social involvement and to some extent we can see this happening with the personal homepage. Individuals are reaching out to a global mass audience to say, â€Å"this is me†. Grosswiler notes that Mcluhan â€Å"would have agreed with the idea that electronic media increase the desire for closeness and intimacy in the Global Village† (Grosswiler 1998:118). However there is a problem in defining what we mean by â€Å"closeness and intimacy†. A personal webpage is more personal than the BBC homepage but not as personal as face-to-face communication. Mcluhan would argue that the â€Å"closeness and intimacy† on the personal webpage is the only type that exists as we live in the â€Å"global village†. For Mcluhan there was no other village and intimacy could be with anyone, anywhere. There is a tendency by those who consider the Internet in a technologically determinist way to view it in isolation. The Internet is for most people not the totality of their social interaction, although it is becoming increasing possible to live your life without human contact. It is possible to order almost everything you could need using the Internet, yet town centres still exist. I may talk to friends online but the majority of communication with them will be face-to-face. Mcluhan is often accused of exaggerating his conclusions and this is evident. While the personal webpage is popular it doesn’t provide a substantial system of interaction. It also clear that while a minority of people make friends online, face-to-face interactions comprise the majority. Mcluhan’s famous aphorism â€Å"the medium is the message,† represents the belief that the medium itself has social impact of which the masses are usually considered to be unaware. If the power of the media is so great, how is it that determinists such as Mcluhan can stand outside of it to comment? Furthermore Mcluhan thought that as soon as we are aware of something as environment, a greater process must be in effect (Mcluhan, Eric). However, Mcluhan was considered knowledgeable enough to sit on a board set up to examine â€Å"the totality of communications problems in modern society† (McBride cited in Briggs and Burke 2002:258-260). The outcome of this report would have made interesting reading but unfortunately political conditions halted proceedings. Maybe I would be discussing a different concept if the report had gone ahead. Mcluhan once remarked that the one thing a fish is not aware of is water. The water determines everything the fish does yet the fish is blissfully unaware. The point is that we are the fish and technology our water. However this doesn’t prove the argument, it simply explains it. At first glance the phrase appears clever yet contains no empirical evidence and is typical of Mcluhan’s inventive and persuasive useful of language. Mcluhan’s global village is perceived as optimistic. Yet a Marxist interpretation offered by Ang notes that â€Å"the making of the â€Å"global village† can be rewritten as the transformation, or domestication, of the non-Western Other in the name of capitalist modernity† (Ang 1996:150-180 cited in Grosswiler 1998:142). While the idea of the spread of communication remains constant, it is seen to destroy individual non-western cultures to make way for capitalist exploitation. The sociologist Tom Nairn argues that while Mcluhan’s â€Å"global village† could be reality, it is prevented from being so by the social forms of capitalism† (Nairn 1968:150 cited in Grosswiler 1998:34). He is not denying that it is achievable, but notes, â€Å"The potential of electric media is, in fact, in contradiction with a great deal of the actual social world†. He accuses Mcluhan of creating myths and ignoring the contradictions of his theory. The graphic below compare the distribution of Internet routers and the global population. (Soon-Hyung Yook, Hawoong Jeong, and Albert-Laszlo Barabasi at http://www. cybergeography. org/atlas/geographic. html) It is obvious from the map that the majority of the world is not connected. According to this the â€Å"global village† is made up of a minority of the worlds population. This is a model far from creating greater social involvement and has the potential to create a global divide between the connected and the unconnected. In my introduction I cited a statistic claiming that 1 in 6 people own a mobile phone in support of the â€Å"global village† concept. As with Mcluhan’s aphorisms this initially seems persuasive but closer inspection reveals the truth. The statistic suggests proportionality. As Briggs and Burke explain, â€Å"While there were 600 million telephones in the world in 1982, half the world’s population lived in countries which together had fewer than ten million†. Again this undermines the â€Å"global village† vision and adds empirical weight to Nairn’s criticism that the potential of the media is in contradiction with reality. As with the Internet, the â€Å"global village† is presented here as almost exclusively existing between developed western countries. Mcluhan’s vision dictated that minorities couldn’t fail to be incorporated, yet they have been excluded by virtue of being unconnected. Furthermore the Marxist view upholds that where third-world nations are included, it is only as means of stripping them of identity for capitalist ends. These points considered, it seems that Mcluhan’s vision is not a reality. Much of the world is unconnected and I need cite no evidence that it has not led to world peace. However, it should be noted that Africa is currently leading the way in the realms of mobile phone ownership. It has become the first continent in which the number of mobile phone users exceeds that of landline subscribers. A report â€Å"has estimated that there will be 60 million people using mobile phones by the end of the year – more than double the 27 million who have a landline† and mobile phone ownership is growing at an annual rate of 65%, double the global average (Guardian, May 2004). It seems that we may be fast heading toward a â€Å"global village†. However even with Africa’s growth in mobile phone ownership, this still only brings the total to 6% of the population (Guardian, May 2004) and Internet access is considerably lower. While it may be true that a virtual village has been created, it is far from the all-inclusive global vision that Mcluhan prophesised.

Human Mental Health Service Worker Essay

Skills & Characteristics of Mental Health Human Service Workers Skills & Characteristics of Mental Health Human Service Workers Human Service Workers are made up of a group of people that choice to help those in need. Those service workers that decide to work with the mentally disabled are very special people. The workers are trained to assist with the emotional issues that usually bring the client to the point they are at. There are also other causes that can be a part of the reason behind the challenges people with mental illnesses deal with. There could be illnesses that are passed down from previous generations or chemical imbalances at play. In order to be a successful mental health human service worker, there are traits that one must have. In the following paper, it will become clear what skills and characteristics a Mental Health Human Service Worker maintains. Human Service Workers in the Mental Health Field are social workers who strive to make more productive options for their clients. They help the client obtain the treatment required for better health. There are also some cases where family connections are needed to assist in the client being restored to his or her best mental health state. Human Service Workers become a part of their client’s life in some cases can even be more like a life coach because the client depends on them for a chance to feel whole again mentally. When a person struggles with mental illness, there is a battle for that person as they are trying to find their place and feeling different is very difficult to handle. This is where Human Service Workers come into play. Service Workers have to have compassion for others and they have to have a desire to help others. These are characteristics that are a must in order to be a good Human Service Worker. The Human Service Worker is like a life coach to the client. Each session has to provide them with a life skill and an assignment for them to complete. This is part of the recovery process because there is an ending to the process. There are stages and with each stage there are lessons that are learned. Even though the Service Worker become a major part of the client’s life as the process continues and draws to an end, the client needs to be prepared to work without the Service Worker and understand they must take what they have  learned and continue to use those lessons in the everyday life to keep growing and bettering themselves. Education is a key factor for an effective Human Service Worker, there are many years of schooling that are required. Training and knowledge is just the beginning of what is needed to be successful in the Human Service Field. A Human Service Worker must be able to put personal prejudices aside to be able to help his or her client in an appropriate manner. Putting aside personal prejudices is important but doesn’t mean putting common sense aside. Ethics are another key point to success. By having ethics, it enables you to see the entire situation just as it is, know there are things that may not be normal but, at the same time understandin g that what makes there be needs for Service Workers. Finally, not being judgmental is very important because your clients are in need of your help for a reason, the last thing they need is to feel judge by the one person that is there to help them. Education is important however, personal experience is also an advantage that can help the Human Service Worker relate to what the client is experiencing. By being able to relate to your client, it enables you to be able to read between the lines as the client does not always have the ability to say what is bothering them. Sometimes they are talking in circles and personal experiences make it possible for the Service Worker to read between the lines and pull out the causes to the problems the client is dealing with. According to the community support skills standards, there are critical areas of competence such as Participant Empowerment, Community Networking, and Advocacy (NOHC). These are all areas that are very important in the Human Service field. Participant empowerment is allowing the client to be a part of the program including what are the best ways to proceed. The client needs to feel they still have control over their own recovery. Yes, it is the Human Service Worker’s place to lead them in the right direction that will put them back on the path to recovery however, it is vital that the client be allowed to also make some decisions in the process. Community networking also is important in that most clients are unaware of what services are available for them to take advantage of. With the education the Service Worker has, they are also made aware of the different services available, working with these other programs, learning which ones are more valuable in each client situation. Advocacy is another way that the Service Worker enables the client to heal. Advocating for your  client is in a sense is being their voice in a time when they are not able to. This is a huge part of what the client needs, they need to feel there is someone there for them in a time of need. Skills can be developed to help in the formation of a successful h uman service worker by taking classes, furthering education, training courses, and personal experience. Keeping up to date with the changes that take place in this field is very important. Knowing what the latest studies are in the field and even latest treatment plans can assist any human service worker to do their job more effectively and even help them open their mind a little bit more than before this training. There are some people that are natural born helpers in this field. While he or she may feel like they are helping it is important that they also have the education to be able to assist clients. It is true that there are people born to help others and in doing so makes them happy and complete. A natural born helper seems to be more successful in the human service field simply because have the trait of helping others and this is an area they are very comfortable with. There are many different areas where Human Service Workers can assist the mental ill such as Community Mental Health Centers, Youth Services, and Halfway Houses or Prisons. It is clear as to why there would be a need in the mental health centers and prisons but, you may be asking why would there be a need in youth services areas. Drugs and alcohol abuse could be a contributing factor as to why a client may be dealing with mental health issues. Drugs and excessive alcohol could cause the body to go out of sink and there ca n be major affects on the brain. Clients that have addictions which cause them to be paranoid and can even cause them to do things that they would not do in a normal frame of mind. When dealing with clients in this situation, it is important to first place them in an area to dry them out, then you can deal with the client through rehab programs and education. Within the Community Mental Health Center, determining what the cause of the problem is the first step in beginning the recovery process. Depending on what the root of the evil is will determining what program is best for the client. With the halfway house, it is clear that an addiction or crime is apparent so first going back into the client’s child hood to see what caused the client to do what he or she has done. Afterwards, the path of treatment would be different because there are several things to consider. As it has been clearly laid  out, being a Human Service Worker requires being a person that cares for others, doesn’t judge, and has the knowledge needed to help their client again become a productive member of society. In some cases medication is required and in others, simply gett ing the root of the problem and helping the client learn to face that problem, learning how to deal with it is the key to success.
