The Internet, Teaching and Learning essays

The Internet, Teaching and Learning essays Using the internet for learning and teaching purposes can have benefits; however the disadvantages far outweigh the positives. The internet is not the effective tool that it appears to be, with many tertiary students finding difficulties associated with accessing and using this technology. The internet holds a wealth of information; however the quality of this information can be questionable. In addition to this, using the internet requires a certain amount of computer knowledge which students can find difficult to master and there are associated issues regarding accessing information and the related costs involved with using the internet. Students using the internet for study are also at risk of isolation due to the autonomous nature of external study. It is true that much information can be found by simply typing a few words into a search engine and pressing enter. Nevertheless, information can be uploaded to the internet without any scrutiny or evaluation from experts. Alternatively, information that is gathered from printed material will have been thoroughly examined and assessed by an authority on the subject before being published (MacDonald on the internet...anything goes, this means that the authenticity of the information on the internet must be questioned. Singh s more, using the internet promotes casual reading habits. Students who read in an informal manner are not engaging completely with the content, which can result in the production of a more casual writing style (Birkerts in Leibowitz 1999). Along with the issue of establishing the quality of information on the internet, there are difficulties associated with accessing the information in the first place.

Ethical Dilemma Global Business and Emerging Economies Case Study

Ethical Dilemma Global Business and Emerging Economies - Case Study Example The biggest five emerging economies are referred too as the BRICS. The five members of the BRICS are Brazil, Russia, India, China, and South Africa. There is a dark side to the globalization movement. It seems as if ever since this movement began the rich have been getting richer, but the poor are still struggling to survive. The continent that has suffered the most since the start of the movement is Africa particularly the Sub-Saharan region. Most people in Africa are living on income of less than $1 day and they do not have enough money to eat properly everyday. While people in Africa are dying of starvation, the opposite occurs in Western countries such as the United States where there is so much abundance of food that 33.8% of the population suffers from obesity (Cdc, 2011). Developed economies sometimes are at disadvantage in certain aspects such as cost of living. In the United States health costs are skyrocketing, but in many emerging economies healthcare is a universal right and the government pays for all medical costs. In many of these countries there are no applications of patents which helps keep the price of prescription drugs low. Overall the standards of living in developing economies are much higher than in emerging economies. The United Nations should do more in order to transfer the wealth better among the world’s nations. ... ndustries such as the pharmaceutical industry can impose new ethical regulation to raise the bar and make industry concessions to accelerate the process towards redemption to certain patients. For instance the HIV/AIDS epidemic requires the industry to impose a cero profit policy. All drugs and research and development for this disease will be treated as if the corporations were non-profit organizations. All countries across the world will amend their tax codes to provide credits for R&D for HIV/AIDS as well as tax deductions and credits based on distribution quotas for HIV/AIDS medicines. There are other alternative solutions to help alleviate the imbalance distribution of wealth worldwide. A way for the developed nations to directly help emerging economies achieve growth is by a direct transfer of funds. The 54 developed economies of the world will impose a 5% redistribution tax based on the gross domestic product of each country. The money collected from the tax will be distribute d to the emerging countries that fall in the lower 25% percentile of gross domestic product per capital among the emerging economies. The 39 poorest countries in the world will receive the economic incentive from the collection of the tax. Aggressively investing in emerging economies can help improve the standard of living of a lot of people. This strategy seems like a socially responsible tactic, but businesses cannot forget that their goal is to make money. A business person should choose the option that makes more economic sense when implementing international expansion strategies. Investing in a foreign developed economy has a lower risk than investing in an emerging economy. A way to facilitate foreign investment in emerging economies, while at the same minimizing the risk of

Yosemite Overcrowding Essay Example | Topics and Well Written Essays - 500 words

Yosemite Overcrowding - Essay Example Tourism should exist in such a manner that it will not destroy what it is trying to serve. This is morally right. On the contrast, overcrowding in national parks does not save the park environment. This is morally wrong and leads to pollution, soil erosion, vandalism, deterioration of infrastructure in the park, and promotes global warming in the park. In addition, the pursuit of economic gains by allowing overcrowding, at the expense of environmental preservation is morally wrong. Yosemite National Park is one of the national parks in the U.S. that are faced with great overcrowding. The Yosemite Valley was set aside by President Abraham Lincoln in 1864 for preservation (Hayes Web). Since then, people have had the opportunity to enjoy recreation and amenities that have enhanced their experience in Yosemite Valley. However, this privilege faces a threat due to the major problem of overcrowding in the park. Overcrowding is known to have detrimental effects on any park and the environment. In Yosemite Park, there are only 1,100 parking spaces. However, there are more than 8,000 cars that pass through the Yosemite Valley (Central Sierra Environmental Resource Center Web). The large number of people visiting this people puts a strain on the resources in the park. For instance, this has led to degradation of the park air, a lack of parking, and straining on the Merced River (The New York Times Web). There is therefore, need to regulate the public access to the park in order to enhance conservation of the Yosemite Valley. The problem of overcrowding in national parks is a major ethical issue. This is mainly because it is the right of people to visit parks and experience nature. Therefore, stopping people visiting parks in order to avoid overcrowding would be infringing on their rights, which is morally wrong. Nonetheless, it is possible for the management of parks to reach an ethical decision that will ensure that overcrowding in

Second-Impact Syndrome In High-School Athletics Research Paper

Second-Impact Syndrome In High-School Athletics - Research Paper Example Many studies focusing on organ damage during competition focus on short-term, immediate damage due to blunt-force trauma with a limited time window, and minimal long-term followup to control for the possibility of lasting symptoms or lingering health problems as a result. (Cantu, 2003) Thus, there is still considerable need to examine and quantify a risk of death that would otherwise be dismissed; and to characterize this threat through a variety of statistics. Second-impact syndrome (SIS), a term originating in 1984, is described by a Dr. David Cifu and other colleagues as a "situation in which an individual sustains a second head injury before the symptoms from the first head injury have resolved." (Cifu, 2010) The second trauma for an athlete is likely to occur days to weeks following the first, in high risk sports. Loss of consciousness (syncope) is not necessary for dangerous complications to set in. (Bey, 2009) an impact which may seem of little consequence at first, wherein the athlete may seem to be only momentarily dazed can have a profound effect. But the effects of this second impact may result in cerebral edema/swelling and herniation, creating a slow bleed within the skull. This hidden crisis can trigger a seemingly healthy athlete to suffer fainting and fatality within minutes. (Bey, 2009) Dr. Cifu reports a mere 17 cases of confirmed SIS (Secondary Injury System) that have been dignified with descriptions in the medical liter ature. Much work still remains to describe the true pathophysiology and medical risks of SIS. (Cifu, 2010) Although Bey and colleagues have identified 35 apparent cases of the condition over a course of 13 years of examinations of football players. (American) Although similar corroborating injuries are not universally reported, even among higher-risk sports; such as Australian football which claims eight times the frequency of concussions as the American game. (Bey, 2009) Â   Certain young athletes may not comprehend or recognize the warning signs of concussions or may believe that minor injuries do not constitute a risk sufficient to stop them from playing. A medically-reviewed guide in the New York Times as well as Mayo Clinic sources have compiled a list of early warning signs to assist with recognition of the dangers and symptoms, which can range from mild to severe. (New York Times, 2011) They can include: 1. Altered consciousness, feelings of drowsiness, difficulty in awakeni ng, or similar deficits. 2. Confusion, ‘spaced-out' feeling, clouded thinking. 3. Headache. 4. Loss of consciousness 5. Amnesia, either retrograde or anterograde concerning of events before the injury or immediately after it. 6. Nausea and/or vomiting. 7. Visual hallucinations; such as flashing lights. 8. Fugue states or "lost time". (New York Times, 2011) 9. Ringing in the ears is another possibility according to Mayo Clinic sources. (Mayoclinic.com 2011) In many cases, minor concussions - while dangerous will still allow time for the patient to receive medical attention. But secondary insults are still a risk. Before SIS becomes a factor medical intervention should be a possibility. (Mutlu et al. 2003) Worth noting are certain warning signs that indicate immediate danger in regards of emergency symptoms of a concussive injury. Young athletes or indeed anyone suffering head injuries should seek immediate medical assistance at the onset of: 1.) Changes in level of alertness an d

Holography: From Physics to The Big Screen Essay -- Cinematography

The technical evolution of film industry is one notable feature of modern civilization. The innovation of combining motion pictures with recorded sound. Black-and-white film gradually replaced by the colour motion picture film and the visual effect involve the integration of live-action footage and computer generated imagery to create a scenes which look realistic, but would be dangerous, costly or impossible to be recorded and the popularization of three-dimensional cinema. The developments of technique contribute the film industry to get closer to people’s perception, however, in the real life. The observation of objects would change if we look from different distance and angle. And this experience of perception cannot be done in film. Because of the lack of stereoscopic impression of film images, it limits our sense so that the actual we see might be different. In 1920s, Sergei Eisenstein had predicted that the future of cinematography was tridimensional and there are many other film pioneers hold the same view. What most film histories leave out is that the Lumià ¨re Brothers were trying to achieve a three-dimensional image, Louis Lumià ¨re eventually re-shot L’Arrivà ©e d’un Train with a stereoscopic film camera and exhibited it (along with a series of other 3D shorts) at French Academy of Science. The films were shot in two views of the scene and then printing the film in two different colors and combining them with layered film on one reel. S3D (Stereoscopic 3D) film with better use of polarization systems were invited in 1930s and shown in the public in 1950s, however, after this initial huge excitement, S3D films were not widely recognized. Although the polarized stereoscopic film technology have been improved in all possible... ...nounced that they developed a generator of holograms on a board with a circuit that generates holograms on the LCD panel. The holography had demonstrated its potential. Now holograms are not so distant future any more. The idea of the holographic movies started becoming popular among filmmakers. Andrei Tarkovsky said, "The most important thing for cinema is for it to become holographic". A hologram can be made not only with the light waves of a laser, but also with sound waves and other waves in the electro-magnetic spectrum. Acoustical holography can see through solid objects by using sound waves. Microwave holography detects images by recording the object’s radio waves. Some holograms made with ultraviolet light can record an image of particle such as atom or molecule. Holography is one of the most significant discoveries humankind has ever made.

Love and Sacrifice Essay

Sacrifice is one of the purest and most selfless ways to love someone. There is no better way to show one’s loyalty or love for another than through sacrifice. The Kite Runner clearly demonstrates the sacrifices individuals made to make the ones they love happy. In Khaled Hosseini’s novel The Kite Runner, a little boy named Hassan demonstrates love and sacrifice the most. Hassan admires Amir an immense amount and his loyalty towards Amir is always present in everything he does. He constantly sacrifices things for Amir and does whatever he can to make Amir happy and Amir’s father Baba, very proud of Amir. Hassan makes sure Amir is always pleased and does anything and everything Amir tells him to do. Hassan has an unconditional love and loyalty towards Amir that he does not falter no matter how badly Amir treats him. Hassan is absolutely selfless; to a point where he sacrifices himself for the one thing he knows Amir has craved his whole life, his father’s admiration. When Hassan goes running for the blue kite, Amir asks him to come back with it and Hassan replies â€Å" For you a thousand times over!† (pg.71). Hassan has two choices; to give the blue kite, which will consequently betray his best friend Amir, or to be punished by Assef and his friends and keep the kite. His devoted love to Amir results in a horrible sacrifice. Hassan gets raped and does not even think twice about giving up the blue kite, the key to Baba’s heart. He stays loyal to Amir even though he pays a hard price. Hassan has always taken the blame for things Amir does or farthings Amir makes Hassan do. Hassan being the selfless person he is never speaks up for himself knowing that will only get his dear friend Amir in trouble. Hassan’s final sacrifice for Amir is deliberately planned by Amir himself. Amir cannot withstand the pain and guilt of knowing that he does nothing to help  Hassan from getting raped; he is selfish and a coward. He is reminded of this every time he looks at Hassan. He thinks if he can find a way to make Hassan and his father the servants of their house, Ali will then leave and rid him of his guilt and suffering. So he plants his new watch under Hassan’s bed and then accuses Hassan of stealing it. Knowing that Hassan will never disappoint him. He waits for Hassan to respond when Baba asks him if this is true. â€Å"Did you steal that money? Did you steal Amir’s watch, Hassan?† Hassan lies †¦ â€Å"yes† (pg.111) this is another sig nificant event where Hassan put Amir before himself selflessly. Baba Is always perceived as a wise man with strong morals and opinions in â€Å"The Kite Runner†. He is not a coward nor selfish, he stands up for what he believes is right and Baba is a very brave man. This is displayed when he sacrifices his life for a woman he does not know. He stands up and says, â€Å"Tell him I’ll take a thousand of his bullets before I let this indecency take place†. (Pg. 122) This act stops a Russian soldier from raping a woman that is carrying a baby on their way to America. This shows the love Baba has in his heart to help this woman from a terrible event that would have taken place if he had not stopped it. He has shown love and sacrifice for women he does not know and that shows his good character and bravery. Although Amir had feels his father never appreciated him enough his father makes a big sacrifice for Amir. With the war-taking place in Afghanistan, Baba knows it will not be a safe place for Amir to grow up and knows he has to do something about it. He leaves everything he has behind. He sacrifices everything he has for Amir, all his belongings, and his house, and where he grew up. He leaves his life behind so Amir can have a happy and safe life in America. He does not like America but he knows it is best for Amir. He puts Amir before himself, demonstrating another one of Baba’s selfless acts. Throughout the novel, Amir has some very negative personality traits. He is selfish, demanding, cowardly, disrespectful and jealous. He does not seem like the type of person that will do something for another out of the kindness of their heart. He always thinks about himself and what he wants. He has never sacrificed anything for the people he loves. Growing up with  the memory of Hassan’s rape still fresh in his mind like a situation that has just unfolded has finally opened his eyes and makes him realize he needs to be brave for once in his life. So Amir acts. He goes back to Afghanistan to find Hassan’s son, Sohrab. Rahim Khan’s advice, â€Å"There is a way to be good again† (pg.2) helps Amir to put his feelings into action. Assef, now a Taliban officer, beats Amir up badly, but this, heals Amir of his wrong doings from the past and he takes Sohrab back to America with him to live a good life. Amir finally puts someone before himself after all the sac rifices Hassan has made for him in the past. This shows the love and sacrifice he makes for Hassan’s child knowing it is the only way he can ever repay Hassan for the years of mistreatment in their childhood. The Kite Runner by Khaled Hosseini demonstrates a very good lesson on sacrifice and love. The novel is a perfect example of the ways Jesus shows us how to live our lives. â€Å"There is no greater love than to lay ones life down for a friend†.

Process Encouraging The Mentee Help Bring Together Their...

MOVING TO SUSTAINABILITY The next step is to embed this process encouraging the mentee to bring together their perceptions, reasoning, emotions and aligning this to their goals. This is itself can pose a trap (Kets de Vries and Korotov 2007) for mentees if they have not integrated a critical learning approach to their complex problem solving situations. If they have not, then the outcome is nothing better than surface learning characterised by double loop learning where they become puzzled and wedged between different viewpoints, assumptions and conflict. Things become â€Å"undiscussible† (that is not up for discussion either implicitly or explicitly) enforcing one or other to suppress their voice, to silence them and to feel intimidated. The mentor through the mentoring process assists mentees question their repeated thoughts and actions so that they can untangle themselves from this self-defeating spiral. Avoiding or ignoring it will not resolve this problem. A dynamic reflective process between me ntee and mentor establishes a framework for deep learning, assisting the mentee to making sense of their challenges, which ultimately provides greater insights regarding their intra and interpersonal conflicts. Resilient mentoring is aimed at critical and flexible learning and is an advantage for mentees in that it provides them with a process for delving into issues and problems that they encounter. The process allows mentees to foster within them an approach to change their
