My interersting travelling Essay Example for Free
My interersting travelling Essay The advantages of group learning As students are trained in the form of credits you probably already know and familiar with concepts such as group exercises , group discussions , group work But not with any student or group of students who also exploit the positive approach of this study . The cause of this situation comes from the students who , or sometimes from the other objective reasons . The advantage of this method of learning is almost always students aware and undeniable . Learning environment group will actively promote the learning of individuals , creating cohesion in a community . While working in groups , the contradictions that arise from student to resolve conflicts . From there , they will have the ability to resolve conflicts , to convince others of the situation may be encountered in later life . The spirit of learning and the ability to listen to others and will be what students will learn . These skills are very important when you step out of the work environment and this would be a good premise to know how to work in a team environment . Work , group discussions, not merely at the request of teachers set for students , but more importantly it is the study of student research . Study groups will gather opinions of individual creativity , from which the product will be rich academic creativity . The best method will be selected from the comments yet. Learning products will now also be the result of all the members . School groups are not effective , why ? The positive aspects of group learning methods is undeniable . But no group of students also achieved the highest results with this method of learning , even sometimes some students feel it brings a lot of forms and achieve less effective than individual work people . So the reason why ? First, a number of students considered that the group work exercise ofà collective psychology so often not my job , everyone except himself . As a result, no one common father cry . Many think that school groups will be very comfortable as it is a form of learning by playing , learning to speak , thrown across his back turned another thing about this table It s so wrong . Since you are self- wasting his time in vain . Second, learning requires self-discipline team of each team member . The work is similar to the operation of a production line . Lines will not work , or work less effective if a part does not work or does not work properly function . If a team member does not work as assigned will result in the group will work stalled . The third reason , which is the division of labor is not clear . Sometimes a team member to take on too much work , while members have nothing to do . The work of the group is often put too much for the leader , sometimes even product is the result of individual rather than the leader of the group of products . Conversely , sometimes the leader hug too much work for her to lead the others self-love and the result is uncooperative . How to learn good team ? There are many causes of this learning method is not effective . Both objective reasons and from the school itself . So how to approach learning the most effective team ? First of all assigned work is reasonable . This depends on the role and ability of the leader to direct . When the work is clearly divided for each member they will be aware of his role , is responsible for completing the work . It is especially important to say to the self- consciousness of individuals in groups , students should find themselves responsible for a part of it , and the finished product has a contribution herself . A group is only effective when the members have self-consciousness : self-awareness of time , homework , self-awareness speech Only when each student developà highly independent spirit , think about issues that need to provide learning research group that studies the group , the new group is promoting effects .

Role of UNICEF and the International Labour Organization in the Working
Introduction This paper deals with the role of transnational actors like UNICEF and the International Labour Organization (ILO) in the working childrenââ¬â¢s movement. It examines the role of development communication in empowering working children, and its impact on the movement. The paper begins with a brief introduction to development, linking it with issues concerning working children. It then goes into a brief overview of UNICEF and the ILO, and talks about the role of each in the international working childrenââ¬â¢s movement. It evaluates one program executed by each of the organizations in dealing with a development situation, in terms of intent and purpose, policies and procedures, obstacles faced, and the outcome of each effort. I then present my critique of strategies followed by both actors and my conclusion from this comparative analysis regarding the effectiveness of each actor. As this is a topic that has been of concern to me for a while, this analysis might appear to be a bit subjective to the reader, but I have tried to bear in mind objectivity, and did extensive research on both organizations to make sure that I was looking at a wide enough body of work. The research consists mainly of information I found on both websites as well as a few books and journal articles. It also comes from the first hand experience of a non-profit organization that works with issues concerning working children, who have worked closely with the ILO and the United Nations. A transnational actor can be defined as a person, business or organization that operates across borders and has some impact on world societies and environments. It became apparent to me as I was doing my research that transnational actors often have admirable... ...tion to make sure the projects are meeting their goals. There needs to be constant monitoring of each new venture undertaken. Detailed evaluations of current projects and research for new strategies in place of older unsuccessful ones are essential, to make plans better cater to the needs of the children. Lastly I think there needs to be increased government and non-profit participation, and involvement of the children, to bring about the best kind of development. From a development communication standpoint, I think the ILO manages to utilize the most optimum model to bring about progress and change the status quo, wehreas this is largely lacking in UNICEFââ¬â¢s approach.

Is there a market for wool suits that are washable?
Washable wool suits with finest material and craftsmanship are very popular among men. Many Australian and Chinese companies are now introducing machine washable new blend of wool suits for increasing the sale of these suits among professionals. In 2005, a Chinese businessman and movie star in joint venture with Helain Group introduced washable wool blend suits with high quality, special performance and easy care. Helian group is Chinaââ¬â¢s one the largest manufacturers and retailers of menswear. They have around more than 250 retail shops in all over China and production of 3 million per year (Yin introduces, 2005) These suits were made with special blended material to maintain their style and shape even after machine wash. Retailers have always been interested in buying and merchandising washable wool suits to enhance their sales and popularize their use among new generation. Washable wool suits are marketed in key regions of China and Australia and displayed at several trade shows and exhibitions in retail stores. Washable wool suits, which were introduced in China, were made with Australian Marino wool. As these suits were introduced it was expected that demand for Australian Marino wool will increase. These wool suits were specifically introduced for increased performance and new innovative styles (Yin introduces, 2005). In 2003, Australian company AWI and Berkeley were the first to develop the technology of these suits. Later these were introduced in China in order to increase demand for Australian wool. Currently China is the largest buyer of Australian wool. Washable wool suits are also becoming popular among other Asian countries. According to Furong, President of Heilan, introduction of machine washable wool blend suits has put Heilan group at edge of others and a major step in improving their market share. à In addition, he believes that the suits they produced were easy to care, easy washable, convenience and cost effective and has huge market potential in China (Yin introduces, 2005). The need for machine washed and dried suits was also felt among American and UK professionals. Men are usually looking for suits that can be machine washed, dried and can be worn without the needed of ironing. However, one problem they face is wrinkles that appear soon after machine wash ruining the expensive fine suit. The second thing of concern to men is the need of well creased and pressed suits during their jobs and business meetings. Young professionals are more interested in having such suits. For some people suits are not just for convenience but they are worn to increase your reputability and status while you work among the company of respectable people, as noticed by a fashion historian, Anne Hollander (Rohwedder, 2006). Many professionals prefer machine wash than going to dry cleaner because its easy, fast and cost effective for them. ââ¬Å"Kenny Cook, a 37-year-old desk clerk for Royal Mail in London, plans to buy one of the new suits for a friend's wedding later this month. Mr. Cook says he eats lunch at his desk and often drops a piece of his sandwich on his suits. ââ¬ËI can't be bothered to go to the dry cleaners,ââ¬â¢ says Mr. Cook. ââ¬ËBut I've mastered a washing machine.ââ¬â¢Ã¢â¬ (Rohwedder, 2006) According to a report the new machine washable and dryer-friendly wool suits are made with 45% wool, 52% polyester and 3% lycra. That prevents wool to become as a wet as in its original form. Sale of such suits is also going high in UK and USA. However, most men think that these suits are not very hot, scratchy or shiny (Rohwedder, 2006). US retailers like Nordstorn Inc think that wash and dry suits is a great innovation and needs more development. But Catherine Hayward who is director of fashion design at British magazine thought that there is no need to have machine washable suits as these are needed to work at reputable organizations not for gardening or meat market (Rohwedder, 2006). However, different people have different thinking and many have considered a need for machine washable suits. Sales in China, USA, UK, and even in other Asian countries is gradually increasing.

What Is Road Salt Chemical Composition
When cold weather arrives, stores stock up on big bags of road salt and you may see it sprinkled on sidewalks and roads to melt ice. But what is road salt and how does it work? Road salt is halite, which is the natural mined mineral form of table salt or sodium chloride (NaCl). While table salt has been purified, rock salt contains mineral impurities, so it is typically brownish or gray in color. Machines mine the salt, which is crushed and packaged for delivery. Additives may be mixed with the road salt to prevent caking and ease delivery using gritting machines. Examples of additives includeà sodium hexacyanoferrate(II) and sugar. How Road Salt Works Road salt works by lowering the freezing point of water via a process termed freezing point depression. In a nutshell, the salt breaks into its component ions in a small amount of liquid water. The added particles make it more difficult for the water to freeze into ice, lowering the freezing point of the water. So, for road salt to work, there needs to be a tiny bit of liquid water. This is part of the reason why road salt is not effective in extremely cold weatherà when water would freeze too easily. Usually, an extra source of water is not necessary because there is enough liquid water present, either coating the hygroscopic salt pieces or produced by friction from traffic. When cold weather is forecast, it is common to pre-treat roads with brine, which is a solution of salt and water. This helps prevent ice from forming and reduces the amount of road salt needed to de-ice the surface later. Once ice starts to form, road salt is applied in gravel or pea-sized chunks. Road salt may be mixed with dry or damp sand to aid the process, too. Other Chemicals Used as De-icers While rock salt is the most affordable and commonly used chemical to de-ice roads, sand also may be used. Other chemicals are also available. Most of these other chemicals are more commonly used for sidewalks or driveways. Each chemical, including road salt, has pros and cons. One of the biggest advantages of rock salt is that it is readily available and inexpensive. However, it does not work under extremely cold conditions and it does pose significant environmental risks. The primary concern is that the sodium and chlorine get into the ground and water and raise the salinity. Also, because rock salt is impure, other undesirable compounds present as contaminants are released into the ecosystem. Examples of contaminants include lead, cadmium, chromium, iron, aluminum, manganese, and phosphorus. There is no perfect de-icer, so the goal is to use the best chemical for the situation and to use the lowest effective quantity. Note that sodium chloride, potassium chloride, magnesium chloride, and calcium chloride are all chemically salts, so any of them could be correctly termed road salt. The chemicals listed as corrosive may damage concrete, vehicles, and other structures.

In Wisconsin, cheese brine is used as a de-icer. The brine is a by-product thats normally thrown away, so its free. Some towns have tried using molasses to reduce the corrosivity of salt. The molasses is mixed with saline solution, so freezing point depression is still active. The Canadian company EcoTraction makes granules from volcanic rock, which help melt ice because the dark color absorbs heat, plus it aids traction by embedding into ice and snow. The town of Ankeny, Iowa, experimented with excess garlic salt they had on hand. Another option, not yet in service, is to use solar power to help melt ice and snow so it wouldnt need to be plowed or chemically removed. Sources Elvers, B. et al. (ed.)
