Research Design Assignment Example | Topics and Well Written Essays - 250 words

Research Design - Assignment Example The design is appropriate since it reviews high-quality randomized controlled trials, which are key to evidenced-based medicine. Additionally, the design aimed at providing a comprehensive summary of recent literature from scientifically recognized databases. Blueman and Bousfield utilized several online databases while conducting the review. Some of the databases that they used include Medline, British Nursing Index, Athens, EMBASE, and Cumulative Index to Nursing (Blueman, & Bousfield, 2012). Since this type of design often utilizes transparent and objective approach to research synthesis and aims at minimizing bias, makes it appropriate for exploring the particular research question. Blueman and Bousfield concluded that the study provided strong evidence that link the use of larvae therapy to reducing the bacterial load in chronically infected wounds (2012). The authors, Blueman, and Bousfield acknowledge the limitations of this particular study. They point the application of liquid medium for studies that utilized live maggots as a key limitation. Additionally, they note the lack of standardization for the ecological niche of the bacteria as a

UAE Culture and Society Research Paper Example | Topics and Well Written Essays - 2500 words - 2

UAE Culture and Society - Research Paper Example trong implications on the culture and social life of people living in a country, during the pre-oil days the culture and economy of United Arab Emirates can be classified as a desert economy marked by Bedouin lifestyle and culture. Farming was very scarce due to unavailability of water and was only done near oasis. Pearling and sea trading were the most important sources of income of the people living in this area of the world in the middle of the 20th century. The various aspects of Arab culture were very prominent in the culture of the United Arab Emirates because of strong bondage with the other countries of the Arab world. In order to analyze the culture of a country, we have to know the location and geography of the country because these things have strong implications on the culture and lifestyle of the people of a country. United Arab Emirates is located on the Persian Gulf and shares borders with Saudi Arabia, Qatar and Oman. The area of the country is distributed among the seven emirates in a very non-uniform way. 85% of the total area of United Arab Emirates falls in Abu Dhabi and Ajman has a size of equal to a small city. Oases are randomly scattered throughout the desert area of United Arab Emirates and mountains of Hajar which run throughout the country also have a barren topography. The overall climate of UAE can be classified as hot and dry in winter and very hot and humid in summer. United Arab Emirates has a very small population and thus the income and resources per capita are very high. The health care conditions, nutrition levels and living conditions were very poor during the pre-oil times, therefore a marked increase in population was observed after the discovery of oil. Better facilities not only resulted in an increase in the population growth rate of the native population, the development of infra structure created a lot of job opportunities and labor class from various countries of Asia moved to United Arab Emirates, resulting in a mild

Effects of Peer Pressure Essay Example for Free

Effects of Peer Pressure Essay Everyone wants to belong , to be accepted . This is a major reason why teenagers feel pressurized to go along with what others are doing the so called peer pressure. Teenagers are going through tremendous physical and emotional changes as they change from childhood to young adults . There are new responsibilities to be faced , exams to be taken and of course new relationships to be faced . There is rebellion against the rules and ideas that parents impose and so they flock together almost in desperation in some cases. As young people spend more time with their peers outside the family home there are opportunities to do things that they haven t done before such as trying out substances drugs , alcohol and so on . Young people at this stage in their lives often feel very insecure are the changes that are happening to them normal ? Why haven t they got bigger breasts a longer penis , a boy /girl friend and all the rest ? They may even be unsure of their sexual orientation By giving in to peer pressure and uniting in a common `uniform whether of clothing or language they feel stronger and more normal , and meeting with others going through similar problems reinforces their egos , even though this may go against the norms of society in general. As they mature , obtain jobs , move away from the area in which they grew up perhaps , the effects of peer pressure will diminish . see more:essay on peer pressure They will hopefully realize that misusing drugs is not a good thing . Gradually , as they become surer of themselves , most people feel able to make their own decisions as to which music they prefer , clothes to be worn , even their opinions on world issues will be less affected by what their friends think or do . They will make their own decisions about taking drugs or getting drunk . They will feel accepted for who they are , what they are capable of , and though peer pressure continues to affect most people to some extent its effects tend to lessen as maturity occurs Peer pressure has a very strong influence on our decisions; so it is capable of bringing about great change, whether its for the good or the bad of the situation or person. Peer pressure exists for all ages. Pre-teens and teenagers face many issues related to conformity and peer pressure. They are pulled between the desire to be seen as individuals of unique value and the desire to belong to a group where they feel secure and accepted. The result is that often teens reject family or general society values, while feeling pressure to conform rigidly to the values of their peer Your peers are the people with whom you identify and spend time. In children and teens, they are usually, but not always, of the same age group. In adults, peers may be determined less by age and more by shared interests or professions. Peer pressure occurs when an individual experiences implied or expressed persuasion to adopt similar values, beliefs, and goals, or to participate in the same activities as those in the peer group. Peer groups have so much influence, especially with adolescents, because, nomatter how inappropriate it seems to adults, belonging to a group really doesgive something significant to the young person. Peer groups provide a placewhere children feels accepted, where they can feel good about themselves, andwhere their self-esteem is enhanced. Some psychologists also point out thatlife become simpler when we conform to expectations. Young people tend to gravitate toward other young people with the same problems and in the same situations as themselves and where they feel they will be understood and accepted.There is a very, very strong need to satisfy that thirst for unity and for acceptance. The feeling of belonging is a very powerful force that can outweigh ties to church, school, family, or community. In addition to the feeling of belonging and not being alone or socially isolated, some characteristics that peer groups offer which make them attractive and that families may lack are: (1) a strong belief structure; (2) a clear system of rules; and (3) communication and discussion about taboo subjects suchas drugs, sex, and religion.

The Pros And Cons Of Desalination

The Pros And Cons Of Desalination Desalination is a technological solution that some believe would provide ample supplies of additional water resources.   Discuss the pros and cons to this technological solution and whether or not you support it.   Less than 3% of the earths natural water is viable for human use and consumption. This brings light to the need for a solution to the quickly depleting resource in the rapid growth of population, industry, and increased overall use of water. What is desalination? Put simply, desalination is the conversion of seawater and or brackish water into consumable quality water. To elaborate, this process can be done through a few different methods depending on the location and need for quality, the main process being distillation and reverse osmosis (preferred method). Of the more than 7,500 desalination plants in operation worldwide, 60% are located in the Middle East. The worlds largest plant is in Saudi Arabia. In contrast, 12% of the worlds desalination capacity is in the Americas, with most of the plants located in the Caribbean and Florida. To date, there are currently 23 proposed desalination plants on the coast of California. With these facts in mind it is the responsibility of human kind to weigh the benefits and the consequences of this somewhat deceivingly simple solution. Pros: There is no doubt that an answer to the ongoing discussion of the potential exhaustion of water is indeed overdue. With that in mind, facts supporting the use of desalination as a good alternative remains to be seen. One factor supporting the use of desalination is that desalination can provide a backup water source and a partial solution to a growing problem. While some believe that the use of desalination plants can provide an infinite supply of water and make it possible to put an end to the depleting resource, in reality, as idealistic as this illusion may be, it is far from true. Another favorable point includes the idea that desalination can remove drug contaminated water and other substances such as arsenic and fluoride which is an ongoing issue in places such as Asia and sub-Saharan Africa. It should be noted however, that the use of desalination is not currently present in either place, and the likelihood of implementing a plant, anytime in the near future, is most lik ely unattainable due to topographical and economic limitations. Another supporting idea proposes that desalination may reduce the need to take additional water from the environment and, in some cases, offers the opportunity to return water to the environment. In some areas it is proposed that desalination facilities may help reduce the dependence of local water agencies on climate sensitive sources of supply. Furthermore, desalination is currently an efficient and reliable water source in use among military operations world wide including naval ships. It is also used on some cruise ships as a reliable source of potable water. Cons: Desalination is costly not only ecologically but economically. Desalination costs are subjective due to many factors, which include location and methodology, making comparisons complex and estimates vague. For example, Tampa Bay Floridas desalination plant ended up $48 million dollars over its original estimate and is still not in full working capacity due primarily to poor planning. Previous desalination plants have cost in upwards of an estimated $100-$150 million dollar range, just to start the facility, this does not include what it costs to run after it is already built. Although Costs have come down over the past decade, as technology has become more efficient, desalination still perpetuates a cost of approximately $500-$2,000 per acre foot of water (325,000 gallons), compared with approximately $250 per acre foot for water in urban Los Angeles, and $10 per acre foot paid to the federal government by farmers in the Sierra foothills, according to Haddad, the author of Rive rs of Gold: Designing Markets to Allocate Water in California (Washington, D.C.: Island Press, 2000). Furthermore, the assumption that desalination costs will continue to fall may be false, in fact future costs may actually increase. Another negative factor is that more energy is required to produce water from desalination than from any other water-supply or demand-management option in California, this in turn brings to light the concern of further dependence on fossil fuels. Conversely, it should be noted that the use of fossil fuels can and has been reduced in many facilities by using solar, wind and wave energy to power the facility. According to an executive summary by the pacific institute desalination can produce high-quality water however it may also introduce biological or chemical contaminants into our water supply this will weigh heavily on the design and location of the plant and should be monitored heavily by local government agencies to ensure consumer safety. Desalination produces highly concentrated salt brines that may also contain other chemical pollutants. More specifically, seawater contains approximately 35,000 parts per million of salt. During the reverse osmosis, water molecules are strained through membranes while the salt particles are retained by the membrane and result in a reject stream nearly twice as salty (70,000 ppm) as seawater. Safe disposal of this effluent presents a significant challenge. Additionally and perhaps of the most devastating of the negative aspects to this process is the Impingement and entrainment of marine organisms. This is among the most significant of the environm ental threats associated with seawater desalination. Impingement occurs when marine organisms are trapped against intake screens by the velocity and force of water flowing through them. The inevitable outcome of impinged organisms varies between intake designs as well as marine life species, age, and water conditions. Some resilient species may survive impingement and be returned to sea; however the 24-hour survival rate of less healthy and/or juvenile fish is potentially less than 15%. Entrainment happens when smaller organisms pass through an intake screen to the processing equipment. Organisms entrained into processing equipment are projected to have a mortality rate of 100%. The number of affected organisms will, of course, vary with the volume and velocity of feed-water as well as the mitigation measures developed to minimize impact. Lastly, the use of desalination is a concern because with its implementation and commercialization, the general public could potentially begin a m ore relaxed view of water use than they already do. Meaning, if people think that we have manufactured a solution to the need for conservation there will not be a need to be water use conscious e.g. the more we have the more we spend. This can lead to higher costs to the environment, more unnecessary development and less environmental consciousness. While desalination is what some have considered the holy grail of water scarcity issues, the reality seems quite the contrary. One of the most difficult factors being faced in light of desalination seems to be the idea that desalination has not been in use long enough to perpetuate actual evidence of overall environmental impacts. With that in mind, an environmental analysis conducted under CEQA (California Environmental Quality Act) and NEPA (National Environmental Policy Act) should consider the assessment of cumulative impacts not only of the proposed project but future projects (and existing facilities) in the area. These impacts would include the cumulative entrainment/impingement impacts, cumulative energy consumption, cumulative growth-related impacts, and cumulative wastewater urban runoff impacts. These factors are especially important in areas where pre-existing air quality, water quality and ecosystem health are already compromised. More specifically, developed areas wher e water use is higher and environmental impacts are considered / monitored, have the potential of being the proverbial guinea pig when it comes to testing the idea at max capacity. This information should also be part of heavy public education to ensure a full public understanding of its costs and benefits as part of most growing problems in the world come with the lack of education and understanding. Furthermore, there is little evidence that desal plants are any more or any less of an impact than other alternatives, not because they are incapable of causing issues but more because the potential issues have not been fully investigated. Primarily the concern is that the pressing issue and urgency may prematurely cause major environmental impacts (especially long term) to be overlooked or dismissed as something we can conquer at the time it becomes an issue. This vary idea is precisely the reason why most, if not all, environmental catastrophes currently exist. Question is, when is t he woops factor going to cause all parties involved to finally get a clue? In closing, the benefits and consequences of desalination are vast and seem to be vaguely understood. While on some levels desalination should be considered as a supplemental potable water source, many other alternatives which are far less costly economically and environmentally do exist. These alternatives include treating low-quality local water sources, encouraging regional water transfers, improving conservation and efficiency, accelerating wastewater recycling and reuse, implementing smart land-use planning and fixing leaks in already existing distribution pipes and plants. Furthermore a tax deductible option to home owners encouraging water wise appliances and repair allowances should be considered as an encouragement to fix what we already have. For example it is estimated that US Homes Leak 1 Trillion Gallons of Water Annually, which is said to be enough water to supply the entire state of Colorado for three years! Is desalination the answer? To me, it seems a desperate attem pt to band-aid a far larger and blaringly obvious issue. If we continue to use and waste, as a human species, regardless of the solutions we find, our existence will inevitably be self limiting.

The Very Idea of Humanity :: Philosophy Papers

The Very Idea of Humanity Why should we believe in such a thing as humanity? Should we accept appearances or take authority as our guide? Should we point to some pragmatic advantage to be gained by believing it, or is there proof? Philosophy offers such proof, contained in the dream hypothesis of the Buddha and Plato (and, more famously, Descartes). The dream hypothesis reveals our common ground. It refers to a familiar experience in terms of which young people of every time and place can understand why routine, authority, definition and first principle, category, criterion, perception and paradigm might fail. But the dream hypothesis is about the transition from sleeping to waking. As familiar, this transition is an excellent device for teaching that similar transitions can happen to one who is already awake. The dream hypothesis is about the soul, and the capacity to choose not only one's actions but also one's contexts. On the eve of the new millennium, we face responsibility for the results of our routine s. The dream hypothesis promises to awaken a taste for foresight and negotiation. When we all understand the dream hypothesis, we will no longer worship our routines, but will be better judges of their utility. We will stand together when we transcend our cultures and recognize the capacity of all citizens of every nation, tribe, and culture to grow, that is, when we awaken to the possibility of waking up. This is a plea for the dream hypothesis-a sales pitch, if you will. We are here under the banner, "Philosophy Educating Humanity." If philosophy is to educate humanity, the dream hypothesis will help prove to people of all tribes that there is such a thing as humanity. The dream hypothesis will introduce every child to its own humanity, but it will also introduce every child to the humanity of others. The dream hypothesis will increase the number of fully-functioning souls, that is to say, beings with the capacity to decide rationally what game to play, what interpretation to accept, what routine to follow. According to some philosophers, the dream hypothesis is at best useless. Russell said as much in Problems of Philosophy: There is no logical impossibility in the supposition that the whole of life is a dream, in which we ourselves create all the objects that come before us. But although this is not logically impossible, there is no reason whatever to

Comparing the Nazis and the Party of George Orwells Nineteen Eighty-Fo

Similarities between Nazis and the Party of 1984    The government of Nazi Germany greatly resembled the Party, the government in 1984. Both operated similarly and had similar aims. Anything either government did was an action for maintaining power. Both the Nazis and the Party maintained similar ideologies, controlled mass media, educated children in their beliefs, had a secret police force, and had forced labor camps. Both governments used each of these methods maintain power and control over the people. Nazis and the Party had very similar ideologies. Although Nazis eliminated people because of their religion (Sauer 683) and the Party eliminated people because of their anti-Party feelings (Orwell 187), they both tried to eliminate anyone who did not agree with them. This practice was essential for controlling the masses and holding on to power. Retaining power is much easier for a government when the entire population that government rules agrees with its philosophies. No one would attempt to remove the current government from power if he or she agreed with that government. Control of the media was another very effective means of controlling a population. The Nazis established a ministry of propaganda on March 13, 1933 (Sauer 678). This office controlled all media, such as books, newspapers, and films ("Modern World History: Nazi Germany"). The Ministry of Truth was an essential factor in perpetuating the beliefs of the Party and did the same as the Nazis' propaganda ministry (Orwell 39). By controlling any and all mass media, both governments more easily controlled the ideas of the people. If someone were never exposed to a certain idea or belief by the media, most likely he or she would not imagine that idea on h... ...Times 20 October 2001: Overseas News 21.

Chloroplast Tour Guide

Tour guide script! Hello, my name is Seth and this is Mason. We will be your tour guides on this wonderful trip of the chloroplast Once we pass the cell membrane we will see a couple little green nuggets, these are known as chloroplasts. It’s what makes these plants autotrophs or organisms that create their own energy. They have no specific location and are usually spread throughout the cell’s cytoplasm. Alright we are going to pass into this chloroplast here. Once we pass through the outer membrane there is going to be a space between the outer and inner membrane.After we pass through this we will be into the chloroplast. Once inside the chloroplast we will stop by Grana Towers a great hotel complex, which will serve us with free desserts sweetened by the plants sugar itself, isn’t glucose great?! (After Meal at the Grana Towers) Let us proceed with the tour. Now if you look left you’ll see a huge stack of what looks like discs. This is a granum or a stac k of thylakoids. Now look around and notice the natural lighting. All of this light comes from the sun and helps convert carbon dioxide and water into glucose and oxygen.Plants are made green from a pigment called chlorophyll, which absorbs sunlight. This granum absorbs the sunlight inside the chloroplast. And starts what is called the light reaction. Which from the name you could probably tell uses light to fuel the reaction. That’s photosynthesis! As you can see here as we enter the granum. There is a light reaction now occurring. If you look closely to can see these little pigments, as I mentioned before, called chlorophyll. The energy from the sunlight allows water that is also absorbed to split creating oxygen, which is then released into to the atmosphere.This energy is also carried through a system of electrons creating an energy compound called NAPDH. But that’s not all; ATP which is the main energy storing compound in any plant cell is also produced during thi s part of photosynthesis. That was great now wasn’t it? Most of the tourist don’t get to witness a light reaction! You all are very lucky! Now I hope you all are some night owls because we’re going to need to stay up late to witness the Calvin Cycle; the part of photosynthesis that occurs once night comes.Now, for the time being let us return to Grana Towers and we will continue with our tour in a couple of hours. Oh, I almost forgot, Grana Towers will also be providing you with complementary salads for dinner! Yum! (Calvin Cycle) Ok now I know its late but you are about to witness the Calvin Cycle! The part of photosynthesis that occurs during the night. The place where this cycle occurs is in the stroma which is all the spaces in between all of the granum. Since there is no light to use for energy the Calvin Cycle relies on ATP and NAPDH to fuel its process.The Calvin Cycle process results in sugars. You know like the ones we had for dessert this morning! Anyw ay, it creates these sugars by using carbon dioxide which it converts into a 3-carbon molecule then goes through a system of other reactions to form PGAL; this compound allows the plant to make the sugars. I hate to say this! But now it’s time for us to say our goodbyes I really enjoyed your company and I wish you will comeback to once again enjoy this wonderful organelle! Well, Goodbye!
