The effects of tsunami will bring a lot of problem to the nation and community. The effects of tsunami will bring a lot of problem to the nation and community . The general cause of tsunami is earthquakes and it will makes environmental impact and destruction. Firstly,the main cause of tsunami is from the effect of earthquakes. Tsunami, also called seismic sea waves or, incorrectly, tidal waves, generally are caused by earthquakes. Earthquakes can brings volcanic eruptions following to produce a truly awesome tsunami waves . For example ,the Great Kratatau Volcanic Eruption of 1883 generated giant waves reaching heights of 125 feet above sea-level, killing thousands of people and wiping out numerous coastal villages . Actually not all earthquakes generate tsunamis. To generate tsunamis, earthquakes must occur underneath or near the ocean, and must be large . Tsunami can happened in everywhere in the world , but in the Pacific Ocean there is a much more frequent occurrence of large because of the many large earthquakes along the margins of the Pacific Ocean. On the other hand,the effect of tsunami is it will brings environmental impact. Tsunami will destroy all the living things and then brings unbalanced of environment.

Once the tsunami waves have knocked down infrastructure on the shore they may continue to travel for several miles inland, sweeping away more trees, buildings, cars and other man made equipment. In conclusion, all of the people should be educated and improve the knowledge on tsunami issue in order to protect themselves.

What is Online Discussion? Essay -- Technology, Communication

Many benefits of online discussion have been recorded in the literature. For example, participation in an asynchronous online discussion is time and place independent (Morse, 2003: Williams etal., 2001). Participants who involved online discussion can contribute whenever they have a useful input and wherever they are as long as they have access to a network based computer. Williams (2002, p. 266) explained the freedom from temporal and geographical constraints international students have â€Å"flexibility in the time, place and pace of communication† with others. In contrast, the traditional face-to-face discussion does not have this flexibility. Online discussion allows students taking time to think about the messages they receive from their peers as well as what they postings. After a long time practice they can send without the pressure as an immediate responder (Biesenbach & Lucas, 2003). Therefore, online discussion is also defined as "a powerful tool for the development of critical thinking, collaboration, and reflection" (Williams et al., 2001, p. 151). Online discussions are deeply engaged and benefits the diverse students compared with traditional classroom discussions (Crevener, 1999, cited in Pinch & Graves, 2000). Students tend to participate more as they are aware that their participation is being monitored and recorded (Tullar et al., 1998). Online discussion within small groups or learning sets also affords a growing sense of community and a feeling among students that they can get to know each other through this medium (Curtin, 2002, cited in Lewin & Jerram, 2003; Hammond, 2000). Another major benefit of online discussion relates to the fact that in the traditional classroom situation, a few students often domi... ...e way it is used by instructors and students and how it is contribute to the course work (Elgort et al., 2003; McKinlay, 1999, cited in Biesenbach-Lucas, 2003; Weasenforth et al., 2002). The length of the discussion, the number of postings required, the size of any one contribution, the role of the instructor, the students' technical preparedness and so on, need to be carefully considered. Otherwise, the discussion may consist of contributions that are not strongly interactive and the students may simply "play the game" of assessment whereby they make postings that earn marks but do not really contribute to the development of the conversation (Oliver & Shaw, 2003, p. 56). Therefore, some authors offer tips for designing and running a good discussion in a networked environment based on their experiences (Hawisher & Pemberton, 1997; Kimball, 1995; Sullivan, 2002).

Global Political Economy Essay

Sustainable development is defined as development that allows us to meet our current needs without destroying the means of livelihood of future generations. There are three basic elements of sustainable development: (1) economic growth; (2) social development; and (3) environmental protection. Undoubtedly, all of these elements concern our world as a whole. Thus, it is essential to acknowledge that the health of the planet is synonymous with the health of the living beings that occupy it. Protecting the health of the planet is the mutual responsibility of all citizens of the world. Since the planet is limited with respect to its size and resources, it is a sure responsibility of all governments of the world to collectively ensure that all citizens of the globe have somewhat equal if not absolutely equal access to its resources. There are countless ways to distribute essential resources relatively equally. What is required apparently is more practice than preaching; that is, governments must be diligently finding ways to overcome global economic and environmental problems, and acting on proposed solutions. There are plenty of global issues requiring immediate outcomes and solutions. It would be wise to answer their call with immediate action. The Wal-Mart Effect: How Wal-Mart Affects the Economy Wal-Mart Stores Inc. is the world’s largest retailer, able to force its small competitors to shut down business as well as drive down wages. On a positive note, the retailer helps to keep down prices or inflation, and productivity at a high level. Wal-Mart sells goods at unbeatable prices. It thus â€Å"strikes fear into the establishment of every new industry it considers entering (Shaw et al. ). † Presently, Wal-Mart is expressing its desire to enter the banking industry in the United States. However, the banking industry is thoroughly intimidated by the kind of competition it would have to deal with. Wal-Mart is certain to be of financial service to the low-income consumer – if it does enter the banking industry in the United States, full-fledged. At least one-fifth of Wal-Mart consumers are low-income families that cannot afford to pay the high prices charged by most consumer banks and financial organizations in the United States (Weston). Hence, many low-income families do not have bank accounts in the country. Wal-Mart would like to change that, by offering unbeatable prices in the banking sector as well (Zellner). Whether the retailer has a greater positive or negative impact on the economy is, therefore, debatable. Is Capitalism Good for the Poor? A large number of people around the world are of the opinion that capitalists make profits at the expense of the poor. Others believe that capitalists provide jobs to the poor, thereby raising their standards of living. In early September, 2006, a toxic waste dumping scandal of truly globalized proportions came to light in the Ivory Coast. The Probo-Koala, a tanker chartered by the London-based shipping company, Tranfigura, set off from Amsterdam carrying four hundred metric tons of petrochemical waste to dump in Abidjan, the port city of the Ivory Coast (Vidal; â€Å"Ivory Coast Toxic Tanker Impounded by Estonia†). Tranfigura informed the Amsterdam Port Services that the waste was absolutely â€Å"conventional (Vidal). † However, it was later discovered that the waste contained hydrogen sulfide, which happens to be a poisonous gas, smelling as rotten eggs (â€Å"Ivory Coast Toxic Tanker†). At least ten people lost their lives in the weeks immediately following the incident in the Ivory Coast (Vidal). Moreover, seventy five thousand people are known to have sought medical treatment with complaints of nausea, nose bleeds, breathlessness, vomiting, diarrhea, skin damage, headaches, and swollen stomachs (Vidal; â€Å"Ivory Coast Toxic Tanker†). This incident was recognized as an illustration of the growth of capitalism at the expense of the Third World, regardless of the fact that capitalists provide jobs to the poor and develop their economies in the process.

The Trauma of Killing Essay - 2221 Words

The United States military continues to engage in one of the longest periods of combat operations in our nation’s history. One of the results is an increase in the amount of persons suffering Post-traumatic Stress Disorder (PTSD). According to the American Psychiatric Association (APA) (2000), a precursor to PTSD is the experience of an event or events that involved actual or threatened death or serious injury to self or others. Grossman (2009) argues that an additional factor, the emotional and spiritual response to killing another human being, also takes a tremendous toll on the mental health of returning soldiers. Forty-eight to sixty–five percent of soldiers returning from Operation Enduring Freedom have reported killing an enemy†¦show more content†¦In addition to their role as the official motto of the United States Military Academy at West Point, the words â€Å"Duty, Honor, (and) Country† serve to embody the conditioning that each recruit, both officer and enlisted, undergoes in all military branches. Each soldier is taught that they have an absolute responsibility to their fellow soldiers and the country they serve and to fail to uphold that responsibility can never be justified. This fear of failure, writes Grossman (2009) is one of the primary means the military uses to overcome soldier’s innate aversion to killing other human beings. It is also the fear that allows soldier’s to overcome the fear of death and take heroic actions (Nash, 2007). When a soldier perceives he has failed to live up to these standards, shame may result. The Stages of Killing Grossman (2009) writes that killing involves a series of emotions, beginning with concern before the killing, and followed by exhilaration, remorse, rationalization, and acceptance following the killing. Before a soldier kills for the first time, he or she will often have concerns regarding whether he or she will satisfactorily perform his or her duties or will let down fellow fighters by freezing or in some other fashion failing to properly engage the enemy. This fear of failure is generally mixed with the general fear of being killed or injured andShow MoreRelatedTrauma And Recovery By Judith Herman Essay1723 Words   |  7 Pages In Judith Herman’s book, Trauma and Recovery, she discusses her research and work with trauma survivors.
