Information System Used by Market Essay Sample free essay sample

Segment AMarkets and authoritiess have correlative capacities in industrialisation. Markets are covering with the turning monetary sciences intricacy that accompanied industrialisation. At that point. authoritiess need to discover the sorts of financial framework. a ) Identify the sort of monetary science framework and elucidate the financial highlights of each. Financial frameworks are normally recognized by the degree of specialists commitment in asset designation and merchandise creation. There are three significant kinds of monetary frameworks, for example, free-showcase financial framework. order monetary framework. also, varying monetary framework. Numerous states have a different financial framework somewhat. expecting they consolidate aspects of market and arranged frameworks. In any case. the general propensity of monetary arrangement can much of the time let for order into one of the other three frameworks. Free-advertise monetary framework A market monetary framework is firmly identified with industrialist economy and free undertaking. The interest for products characterizes what is delivered. furthermore, most concerns are in private possessed. We will compose a custom article test on Data System Used by Market Essay Sample or then again any comparative theme explicitly for you Don't WasteYour Time Recruit WRITER Just 13.90/page Those people and houses seek after their ain advantage with no cardinal way and laws. They are totally inspired by overall gain. where the buyers and Sellerss are altogether liable for the picks they make. In add-on. free-showcase gives the outright capacity to fiscal qualities to discover the assignment and appropriation of merchandise and enterprises. These fiscal qualities. in twist. are fixed by the powers of flexibly and request of a few exchange great. Only individuals with adequate power over assets. also, riches. in impossible to miss have the benefit to purchase merchandise and enterprises. much of the time estimated actually incredibly in a free-showcase monetary framework. The money related qualities. which are the solitary apportioning and regulating factor in this financial framework. place the hapless in a clumsy situation who are a tiny bit at a time tossed out of the framework with no dish to riches and the fundamental requests of resource. Moreover. on the off chance that the interest is shy of the flexibly of a few exchange great. the fiscal worth will fall each piece contradicted to a financial worth ascent when the flexibly is inconsistent to run into the turning request of a decent or administration. The capacity of the specialists of state is only restricted to telling the law and request of a state and to ensure that a ‘fair price’ is charged by the Sellerss. In this manner. it implies that. specialists holding no capacity in administrating the financial estimation of an exchange decent. needs to see that the money related qualities taken by the Sellerss is valid and similar with the fiscal worth controlled by the powers of int erest and flexibly. Order monetary framework Order financial framework is other than called each piece arranged monetary framework. It is a monetary framework wherein a cardinal specialists be aftering either straight and by implication sets final result marks. livelihoods and fiscal qualities. Government claims most concern. settles on the money related estimation of merchandise and how exchange products are dispersed. For this sort of monetary framework. the fundamental financial request will be understood by the specialists. As opposed to allowing people the chance to make up ones psyche what they need or need. the specialists chooses these requests for the state. It is somewhat hard for the individual since it is unimaginable for them to cognize accurately what the best is for those residents. Fortunes. wagess. rewards and other monetary advantages like fillip are appropriated on the balance of the joint interpretation of administrations. This is the way order financial framework truly kills the benefit making at single degrees. It doesn’t help with their workers’ rationale since everybody is given a similar aggregate of products and a similar rule of life. For outline. a troublesome working resident will non obtain any advantages from work since they can non increment their measure of life any more prominent than it by and by is and they will do simply every piece much as a person who applies practically no endeavor. Order monetary framework is just inverse to the build of free-advertise financial framework. with respect to the essential lucrative assaults. While advertise monetary framework tends to increase the abundance of a state through the steady method of improvement. order monetary framework favors purposeful arranging of the full lucrative technique for the better outcomes. In reality. such true financial arranging in the long count demonstrates great to better the monetary states of a state. Grouped monetary systemThere are both open and private divisions cooperating in manus to ensure the financial developing of the monetary framework. The market decides the money related worth and allocation of assets in certain parts of the monetary framework and the specialists does in others. Neither the market nor the specialists entirely controls the financial framework. Numerous states have a varying monetary framework to some review. For representation. China permits private responsibility for despite the fact that it controls creation and estimating. The United States specialists meddles with a carefully free market by commanding negligible rewards and plans, for example, cultural security. To some review. consequently. both China and the United States are various financial frameworks. A various financial framework is a monetary framework that answers the three requests both in the commercial center and in the specialists. Those requests are: what will be created with our asset s? In what capacity will these merchandise be delivered? Also, for whom will we deliver these products? In spite of the fact that the United States specialists plays a capacity in our monetary framework. a varying monetary framework ordinarily includes makers working nearer with the specialists than they do in the United States so the US financial framework is as yet a market financial framework. The financial framework a state has depends on what is best for the state. Government play an of import work in this financial framework, for example, limits the market wasteful aspects. flexibly the open merchandise. chop down the spread between the hapless and rich. what's more advance low degrees of joblessness and rising costs. The specialists will try to chop down the pay disparity by implementing income upgrades where higher salary worker is burdened more than the lower pay worker. B ) Discuss the expenses and advantages if a state moves from offer monetary framework towards a free-showca se financial framework. In an offer monetary framework. the cardinal specialists manages arranged variables of creation. Truth be told. the specialists is the finishing up approval to take judgments sing creation. utilization of the completed modern stocks and the apportioning of the grosss earned from their appropriation. Other than. the essential financial occupations will be tackled by the specialists. The spread between the rich and the hapless is nearly nothing. In this financial framework. customers have no pick however need to acknowledge all the assurance made by the specialists. The term free market financial framework implies a framework where the buyers and Sellerss are totally liable for the picks they make. In a way. free market gives the outright capacity to financial qualities to discover the apportioning and circulation of products and enterprises. Other than. purchasers are the 1s who might discover and follow up on the sorts and proportion of good and administrations to be created. In free-showcase financial framework. money related worth instruments will answer all the interest and gracefully requests. In occurrences of interest missing the mark concerning the gracefully of a few exchange great. the money related worth will fall each piece restricted to a financial worth ascent when the gracefully is scant to run into the turning request of a decent or administration. Free market financial framework is other than described by organized commerce with no obligations or appropriations forced by the specialists. In the event that a state moves from offer financial framework towards a free-showcase monetary framework. there will be a few changes in the monetary framework. Let’s us talk about the expenses and advantages if a state moves from offer financial framework towards a free-showcase monetary framework. First. there is more opportunity in free-showcase financial framework because of miss of specialists commitment in this monetary framework. Subsequently. buyers are allowed to purchase any exchange great which they like and in whatever wholes. The advertiser or the maker of a decent can other than deliver whichever stock they need to. Other than. the producers can expand the limit of any single exchange great rely upon the powers of the market. Makers are allowed to set about the perils and wagess related with expansion underway. There is no region mediation in the activity of the powers of the market. Following. houses will ever be hoping to deliver something new to secure before their adversaries. Despite the fact that the capacity of specialists is restricted in free-advertise financial framework. one of its occupations is to secure effects rights. This will incorporate objective possessions rights through licenses. Thus. there are incitements in the free market framework for houses to be progressed and deliver better quality stocks. Clearly there is no affectation for the offer market to be progressed. Similarly long as they produce the necessities. the offer market will be upbeat. In free-showcase monetary framework. houses will deliver whatever customers are set up to buy. Purchaser requests are incredibly fulfilled due to very respond to customer request. The customer is sovereign in the financial framework. Other than. because of the free undertaking factor. there are no confinements on what the houses can deliver. In this manner. there will be an a lot bigger pick of produ cts and ventures in a free market financial framework contrasted and an offer monetary framework. The offer financial framework will be progressively worried about doing sure there are satisfactory indispensabl

Essay about Dbq- the Acquistion of African Colonies

In the period of 1880 to 1914, positive and negative attitudes ascended throughout the acquisition of African colonies. Some thought that it would reinforce Europes economy and government, others supposed it would add pressures to Europe; it end up being a benefit to the economy, strengthen the nation and civilizing Africa. Motivations would be up brought upon the vague consideration about this dilemma. Some of the motivations were seen with positive attitudes about the acquisition with the pro imperialist who benefited the economy in documents 2, 5, and 12. During the acquisition, the purchase of the Suez Canal was seen more of a positive attitude towards the government it was a nationalistic attitude. Benjamin Disraeli discusses†¦show more content†¦His demand that he is in the middle between Russia and France is what his map of Africa looks like (D3). Bismarck was most concerned with power politics on the European continent; his comments regarding imperialism seem somew hat ironic (POV). Careful treaties with native chiefs of Independent State of Congo were made between Mr. Henry M. Stanley and several soldiers having whole villages have been signed away to their Majesty (D6). This was seen as an anti-imperialist attitude because of cultural reasons, villages being signed away it was all negative. Economic negative attitudes are seen when the Resolution of the German Social Democratic Party Congress, 1900 speaks that World and colonial power is pursued for capitalist exploitation and for displaying military force which corresponds to the greedy desire of the bourgeoisie to invest its ever-increasing capital and to the desire for new markets which each country tries to usurp to itself. This had a negative attitude because it’s mentioning how colonial power only brings severe greedy consequences upon each country and should not be enforced. The resolution from the German Social Democratic Party Congress is probably a biased source since as soc ialists they would naturally condemn a capitalist agenda (D9). The motivations behind the civilization of Africa are viewed in documents 1, 4, 7 and 11. Economic motivations and political global power such as the advantages of

The Quantity Theory Of Money And Taylor s Rules - 1497 Words

The quantity theory of money and Taylor’s rules offer quite different perceptions about â€Å"[to what] extent the structural models should enter the monetary policy decision-making process†()that they appear to be on opposite ends of the spectrum on the issue of monetary policy rules. The quantity theory of money, as restated by Friedman, leads to a constant money growth rule. Monetarists believe that â€Å"variation in the money supply has major influences on national real output in the short run and the price level over longer periods, and that objectives of monetary policy are best met by targeting the growth rate of the money supply rather than by engaging in discretionary monetary policy†(). The relationships can be illustrated in the following equation, ∆M+∆V=Ï€+∆Q Where M is the total amount of money in circulation on average in an economy during the period, V is the velocity of money, Ï€ is inflation rate, and Q is real output. In the long-run, neutrality of money works which implies a change in the stock of money affects only nominal variables in the economy such as prices level, with no effect on real variables, like real GDP. In short run, however, assuming V is a relatively stable variable, a positive correlation exists between a change in the money supply and a change in real output. Having taken into consideration the indeterminate effect ∆M has on ∆V, Milton Friedman prudently proposed a k-percent rule, where the money supply would be automatically increased by a fixedShow MoreRelatedScientific Management: Pros and Cons1415 Words   |  6 PagesFrederick Winslow Taylor (1865 - 1915) define Scientific Management or Taylorism with 4 principles as explained in appendix A.

Music a Magicful Medicine Free Essays

Music:A Magicful Medicine Fine arts always have been a good way to express oneself for thousand years. One of them is a magical and a powerful way to affect people,both negatively and positively. Music is not just a way to fun or just an art. We will write a custom essay sample on Music: a Magicful Medicine or any similar topic only for you Order Now Almost everyone loves it,some of them say that they can not live without it. However,above all,music is able to do many things. There are a lot of ways that music effects people. As it was mentioned above, music has both negative and possitive effects on us. But these effects are usually possitive. First of all, and it is the most interesting affect maybe, it can cure diseases. Of course it can not be as effective as pills but it really helps during the cure. Due to the fact that music has an enormous affect on humain brain, it helps Alzheimers mostly and it is used as a rehabilitation. It reduces the worst effect of the disease: it brings back the lost memories. Until today, a lot of patients made a good progress by listening to music. In addition, music also repairs patients’ brains damage, like ‘Kenny Roger Effect’. It is a vacation that shows how music can repair a human brain. Because songs by country performer Rogers were among the stroke patients’ preferred tunes,we were thinking of calling this the Kenny Rogers Effect. ’ was said in an interview by Dr Soto. And interestingly, Rogers’ songs also provided the greatest benefits, according to some study findings. Another disease which music can be used as a cure is cancer, maybe the most dangerous one ever. Just like in Alzheimer, there are a lot of good examples which can prove music’s effects on cancer. Firstly, it reduces stress and makes people feel more cheerful. We all know that what kind of songs we listen to can change our mood easily, we can suddenly start crying or feeling better just by listening to music. During the cancer rehabilitation, patients’ moods, feelings and thoughts are very important. Music can raise patients’ spirit and help them to feel better and less stressful. On the other hand, music is a very good way to learn and understand easily. Because of that, it can be applied education, especially in childhood. Music helps children during their education life. It is a really effective way to make a good progress in education. According to the last researches, children who play a musical instrument are more succesful in their school life than the others. The reason is simple: Playing an instrument makes a lot of parts of your brain work at the same time which is a very beneficial thing,especially for children. By the same token, children who interest in music are also more succesful than the others. There are two benefits of music for children. First, it helps them to understand easily. Today, people goes courses to understand and concentrate quickly. Because by just listening a song (a special song of course) you can do this. Classic music for example is a good alternative. Listening a song from Beethoven can make your brain waves decelerate and this is one of the ways to improve your brain’s capasity. Another good effect of music is that it can improve intelligence. We all have seen a Mozart cd for babies or children at least for once. It is because there are so many examples of listening classic music can improve babies intelligence especially during the pregnancy. The works of Mozart and Beethoven are famous for mental function, because the frequencies used are very specific and place the mind in highly distinctive states. Studies have repeatedly shown that babies IQ rises by 3-5 points. Classic music also can make the memory stronger –not for just babies for everyone- and a strong memory is a good proof of an intelligence. To sum up, listening to music is just a free-time activity for a lot of people but in fact it is like a magical medicine for us. It has unbelievable effects on our body and brain and today these effects are being used as cures for cancer and Alzheimer. In other words, music is like a gift for people.

Blend Wing Body free essay sample

The structure design of bended wing body aircraft for commercial airline transport By Yue Sung (Lance) Fung 10/17/2012 Introduction Today many new design aircraft concept use blended wing body theory, one of the biggest challenge of this aircraft is to design a strong and pressurized structure for safe commercial Airline transport. According to V. Mukhopadhyay the structure of Blended-Wing -Body (BWB) flight vehicle has been a one of the major challenging problem for many year. By comparing the fuselage of a conventional aircraft which is a cylinder shape, the stress level of a flatter shoebox shape type BWB fuselage has a higher magnitude ,because the internal pressure causes blending stress of the whole fuselage instead of the stress act on the skin membrane. Due to the primary design of the conventional fuselage structure are focus on membrane stress, a new design and material are needed ,in order to increase the bending moment of inertia without increase the weight requirement while the aircraft is pressurized . Although a whole flowing Blended Wing Body fuselage provide structure weaker and no as pressurize as conventional aircaft, but new designs of the blended wing body aircraft structure can provide satisfying stress, deflection and buckling safety factors, pressurized body during the critical flight and ground loads. There are three articles discussed in this literature review. According to R. H. Liebeck, the BWB structure is separated into two major components: the centerbody and the outer wings. The Y braced box type fuselage design structure concepts was based on a thick stringer outer surface structure, where the stringers are about 5–6 in. deep in order. Then using internal ribs have Y braces where they meet the skin, to reduce the bending moment on the skin created by the internal pressure across the center body and the outer wing. As a result ,the complete center body pressure vessel is  omposed of the upper and lower surface panels, the rounded leading edge the rear main spar, the outer ribs and the internal ribs payload and does not carry wing bending loads therefore the load can equally balanced however the cabin inside of the aircraft is hard to keep pressurized for commercial flight. At the same time , V. Mukhopadhyay has been stated that using the alternative multi bubble structure configuration instead create a whole body structure on a BWB aircraft. The multiple bubbies body can easily apply to the BWB aircraft internal structure, where the center distance between each segment was kept as same as the radius, therefore the outer side and the inner cabin wall junction are facing 120 degree each other, as a result a equal angel geometry given an advantage structure when the membrane stress equilibrium force acting between the cabin wall and the outer shell by balanced by inter cabin wall tensioning, which can keep the inter cabin more pressurized. Comparison to V. Mukhopadhyay , L. U. Hansen, stated that the loading of the structure leads to high bending loads in every part of the cabin can be reduced by structural elements carrying the vertical force components in result the reduce the blending force in the cabin which keep the fuselage pressurized . The solution is to use a strong structural components panel in the membrane which connecting both upper and lower side of the fuselage ,and there are four fuselage surface composite panel configurations were analyzed and optimized for minimum weight, under required internal pressure and estimated compressive loads with both stress and buckling constraints. Although the skin/stringer outer surface structure can apply to the whole structure of the BWB with really strong component against the blend stress , the fuselage surface composite panel also will be a good consideration for strengthen the structure of the outer body of BWB aircraft since it can enlarge the skin stress of the aircraft the keep it more pressurize. Yet the multiple bubbies cylinder configuration can be most effective when it applied to the center body of BWB because of the circulate configuration will reduce the membrane stress and easier to keep the fuselage pressurized than skin/stringer configuration. Discussion R. H. Liebeck method can applied to can applied to the blended wing body aircraft while the Y braces box structure is really sturdy over the upper and lower surface panels, the rounded leading edge the rear main spar, the outer ribs and the internal ribs payload. The design does included carry wing bending loads therefore the load can equally balanced . However the design cabin pressure load is experienced on every fight and fatigue becomes the design conditions. Since the structure is no in a circle it cause the cabin pressure loads are taken in bending, the margin required for aluminum could be forbidden , therefore and advance carbine composite. Other studies said that if the structure are not built by composite material the structure of the BWB will be heavier than the conventional aircraft which in result having less advantage of building BWB aircraft as predicted . Although the Y braces with skin and stringer structure from R. H. Liebeck article will required higher weight without advance composite, L.U. Hansen, stated that the BWB body aircraft outer shell structure can be connect with different type of the . The strong structural components panel can be bonded and connect each other , the different size of the panel and represented the different airfoil surface of the BWB aircraft. When compared to the stringer and the membrane , components panel on every can provide better connecting both upper and lower side of the fuselage also it blend moment can be reduced by structural elements carrying the vertical force. The challege of the design is to hold the panels connection during higher G loading and abnormal maneuver ,and the each panel have to the make it as less tolerance as possible to reduce the induce drag and the turbulence drag from the gap from each panel. To improve the first two solution, the alternative solution state by V. Mukhopadhyay is to use the multiple bubbies fuselage ,during the experiment the multiples cylinder body can remodel the advantage of the pressurized cylinder body of the conventional aircraft. The experimental result shown the design loaded of the cylinder fuselage his the same pressure stress and loading when using the two bubbies and three bubbies structure. When the number bubbies structure increase the pressure loading decreased while the blend moment increase. Although compare to the first two method the blending moment may if the bubbies number increase to three of four , however the design show that the pressurized load of the multiple bubbies construction can provide more pressure load than the skin / string structure and the component panel structure. From the test result of V. Mukhopadhyay article Von-Mises stress of the top surface of the aircraft combined the top and bottom internal cabin pressure. These stresses were well within allowable limits and about 25% lower than the four-bubble design with about 10% increase in unit weight/floor area. Therefore multi-bubble fuselage appear to be significantly better compared to the component panel design and Y brace skin / string structure. As future evidence, NASA build a unmanned BWB aircraft to optimize the structure design due reality flight situation, their structure design was using the multiple bubbles Structure and component panel adding on top and the bottom to prevent the blend moment. The multi-bubble type fuselage which has better stress distribution, for same material and dimension, can be the most effective , further design will be more focus on the combination of the component panel with multiple bubbies fuselage with can reduce the blending force and buckle force while keeping the pressure loading which required for commercial flight.

Alternative Energy Research Paper

Alternative Energy Research Paper Free Online Research Papers The worlds sources of fossil fuels are drying up faster than the earth can renew them. Fossil fuels, like coal and oil take the earth thousands of years to reproduce so an effective alternate energy source must be explored. For many years we have been running out of oil. This phenomenon is called the Hubbert peak theory also known as peak oil. Hydrogen is a great option to power an engine. To make hydrogen we can decomposition methane or using electrolysis. There are two methods: combustion, and fuel cell conversion. Nuclear power is also an option to powering a vehicle. As we all know we have to use uranium to produce nuclear power. Biofuel is a fuel that comes from biomass, living organisms, like cow manure. This area is very active, because it can convert biofuels and other fuels into fuel cells (Biofuels) Alternative Energies The worlds sources of fossil fuels are drying up faster than the earth can renew them. Fossil fuels, like coal and oil take the earth thousands of years to reproduce so an effective alternate energy source must be explored. Fossil fuels or crude oil has been around for a long time and can be refined to form a number of products. Such products include gas, naptha, gasoline, kerosene, gas oil or diesel, and other things. This form of an energy source is used in many things such as generators, electricity, automobiles, aircraft, watercraft, and many other things. While this is a very strong and versatile energy source it still is an excellent energy source. We are also running out of crude oil, a non-renewable resource. For many years we have been running out of oil. This phenomenon is called the Hubbert peak theory also known as peak oil. The peak oil theory states that every finite resource has a beginning, middle, and an end of production. Production of oil usually follows a bell shape curve when graphed. When oil production reaches the mid-point of its life it also reaches the peak oil production. This theory was developed by the geologist for Shell oil, named M. King Hubbert. In the 1960s Hubbert predicted oil would peak 40 years from then, putting peak oil production right about now. Since oil is running out we have to start thinking about alternative fuels that are available to us. The problem is not whether these alternative energy sources exist or nor, they do. Should the government fund and give large tax breaks to research into alternative energy sources. Alternative fuel is any other method of powering an engine without using petroleum. Some of these alternative fuels and methods of powering an engine or the economy are: coal, hydrogen, nuclear power, biofuels, Athabasca Oil Sands in Canada, Venezuelan Orinoco tar sands, green alternatives, and Thermal Depolymerization. These are just few of other methods. The majority of these alternative fuels are arranged to be cheap, non-polluting, and infinite sources of energy. (Hubbert Peak Theory) Coal is a fossil fuel dug up from the Earth by deep mining. Coal is an extremely important source that produces electricity worldwide. In the United States coal produce over half the electricity consumed by the nation. Coal can be produced into oil by gasification and liquefaction (Coal). This process is called synthetic oil from coal (Life After the Oil Crash). This is a good process because it does not contaminate the environment. However, coal is not as great as it seems. Coal production will peak approximately 2 decades. If demand remains frozen at the current rate of consumption, the coal reserves will indeed last roughly 250 yearspopulation growth alone produces the lifetime to some 90-120 yearsthe use of coal for conversion to other fuels reduces the lifetime of coal to less than a human lifespan (Life After the Oil Crash). Hydrogen is a great option to power an engine. To make hydrogen we can decomposition methane or using electrolysis. There are two methods: combustion, and fuel cell conversion. In combustion, hydrogen is burned like in traditional gasoline cars. The combustion cars burn hydrogen directly, and produce water vapor, which is non-polluting. In fuel cell conversion, hydrogen is turned into electricity through fuel cell, which powers the engine (Hydrogen vehicle). Fuel cell conversion is highly efficient. However, there are problems with this method. The problem with combustion is that hydrogen fuel is used rapidly. The first problem fuel cell conversion has is that hydrogen has a low density. Meaning that the amount that can be stored is limited (Hydrogen vehicle). The second problem is the expensive cost of making a reliable fuel cell that would provide electric power in a hydrogen car. Fuel cell designs require the use of platinum, and platinum will become scarce soon (Life After the Oil Crash). The third problem is that hydrogen is an energy carrier, meaning that it does not produce energy. It has to be produced by fossil fuels (Hydrogen vehicle). The electrolysis process consumes more energy than it produces. Nuclear power is also an option to powering a vehicle. As we all know we have to use uranium to produce nuclear power. At the rate we are consuming gasoline, there are 50 years left of low cost uranium (Life After the Oil Crash). There are reactors that create inefficient nuclear fuel, which leads to nuclear waste. However, there are more efficient reactors that reduce the amount of nuclear waste. If we use these types of reactors we are still going to have 10,000 to 5 billion years of uranium for use in these power plants (Nuclear Power). However, nuclear power is less convenient than what they state. It is dangerous to put a nuclear reactor in your trunk (Life After the Oil Crash). It is also a problem because we do not have the time or the money to build 10,000 power plants to produce the energy we get from fossil fuels (Life After the Oil Crash). It will take $3-5 billion per plant, without including the cost to repair old reactors, and converting nuclear energy appropriate for cars, boats, and airplanes. It takes 10 years to build one of these nuclear power plants (Nuclear Power). Biofuel is a fuel that comes from biomass, living organisms, like cow manure. This area is very active, because it can convert biofuels and other fuels into fuel cells (Biofuels). Bioenergy develops 15% of the worlds energy use. Biomass can also be used for the making of electricity and heating. There are solid biomasses that can be made into fuel, like: wood, straw, animal waste, husks or shells from crops, and bagasse (Alternative Fuel). There are also liquid biomasses that can be used as fuel: bioalcohols, like ethanol, methanol, and butanol; biological produced oils like, straight vegetable oil, waste vegetable oil, and biodiesel; oil and gases can be produces by methane, and thermal depolymerization. Gaseous biomasses can produce fuel, like: bio-methane, wood gas, hydrogen, and carbon monoxide (Biofuels). However, biofuels has become less efficient than oil. It consumes more energy than it produces. It takes 11 acres to grow enough corn to fuel one automobilefor 10,000 miles, or about a years drivingthe amount to feed seven people for the same period of time Life After the Oil Crash). To replace a small part of our oil supply we would have to turn most of Africa into a giant biofuel farm. Its a great idea, and we can develop it further, but it wont be enough to the rate we consume oil (Biofuels). The Athabasca Oil Sands are large deposits of tar sands that are located northwestern of Canada and Venezuela Orinoco. It is said that Athabasca contains two thirds of total global oil deposits (Alternative Fuel). It contains 1.6 trillion barrels of oil. With the technology we have today only 311 billion barrels could be extracted (Athabasca Oil Sands). Then why not get most of our oil supply from the Athabasca Oil sands? According to the Department of Energy it will only lower oil prices less than fifty cents. It will also take 10 years to come online. It will peak at 875,000 barrels per day, but not until 2025. By then we would need 35 million barrels per day, while the world needs 120 million barrels per day (Life After the Oil Crash). Green alternatives like, solar, wind, wave, and geothermal power are fine ways to power the nation, better yet the world. Geothermal energy comes from radioactive decay from the core of the Earth. Which heats the Earth inside out, and the sun heats the surface. There are three ways to produce geothermal energy: geothermal electricity, geothermal heating through deep Earth pipes, and geothermal heating through a heat pump (Geothermal Power). The most renewable energy is solar energy, energy coming directly from sunlight. Solar power can be made by: generating electricity using solar cells, generating electricity using thermal power plants, generating electricity using solar towers, heat buildings, heat buildings through heat pumps, and heat foodstuffs through solar ovens (Solar Energy). When the sun heats up the earth unevenly, it creates winds. Wind is able to run wind turbines capable of producing electricity. Some areas do not have prevailing wind power so its best to put them offs hore or at high altitudes, the wind is more continuous. Waterpower can be harnessed and used (Wind Energy). Like water is a thousand times heavier than air, even a slow stream of water can produce large amounts of energy. There are many forms of waterpower: hydroelectric energy, tidal power, tidal stream power, wave power, ocean thermal energy conversion, and deep lake water-cooling (Water Power). However, green alternative is not a good idea. The green alternatives have limited capacity, compared to fossil fuels. Californias 13,000 wind turbines generate as much electricity like a single 555-megawatt natural gas fired power plant (Life After the Oil Crash). To replace a drilling platform that pumps 12,000 barrels of oil per day we would have to build 706 wind turbines (Wind Energy). The combined output of all solar cells in the world is less than 40% of the output of a single coal power plant. The amount of energy distributed by one gas station in one day is equal to the amount of energy that four Manhattan size city blocks of solar equipment produces. To power the whole Earth with solar panels it will take 220,000 square kilometers (Solar Energy). These options only produce energy at certain times or conditions of the day. In order to power a small portion of Earth we would need trillions of dollars to build hydrogen-powered cars, trucks, boats, and air plains; need thousand s of dollars to build oil-powered factories; build an expensive refueling and maintenance network; and we would need huge amounts of platinum, silver, and copper (Life After the Oil Crash). All of these alternative energies and fuels cannot compare to the efficiency oil produces for us. These alternatives were too expensive, there was not enough time, and more energy was put in to produce than it produced, or it was an underdeveloped idea. All of the alternative energies need a little bit of maturity to produce something as proficient as oil. Recently many countries have become increasingly interested in indigenous, renewable energy sources, such as tidal energy as an alternate to fossil fuels for the production of electricity. Tidal energy is a huge source of renewable energy and holds great potential for future electricity generation. Tidal power is predictable, unlike solar power or wind energy. Though, even using modern day technological advances the amount of energy generated will still not totally cover and resolve the worlds energy supply problems. Alternative energy is an option that needs to be put into play. It is proven wind generators have a very mild, hardly if any effect on the environment. If anything a bird might fly into the propellers or a cluster of wind generators might somehow generate a magnetic field disrupting migratory birds route during migration season. Another problem would be lack of wind. Imagine if we relied mostly or entirely on wind power, if we had no wind going things would be thrown int o chaos and confusion, people would be helpless in some places, looting would be abundant and many other problems would be occurring. The curiosity of mankind has led to the discovery of various types of energy, the most essential being nuclear energy. It has become such a necessity over the years that humans cannot survive without it. Nuclear energy provides us with relatively cheap electricity, it helps expand the making of drugs and the equipment in the medical field, and the most vital of all, nuclear weapons. When Einstein and Hahn first began exploring this fascinating kind of energy, their intentions were not to use it as weapons of mass destruction. Unfortunately, that is what humans have made of them. Nuclear Weapons are a threat to the world; they are harmful to the environment and its inhabitants, they are indestructible and they cause competition between nations. Nuclear power has been around since the early 1950s. It is clean with the exception of producing of radioactive waste which has to be stored somewhere, plus there is a risk nuclear meltdown. It is still extremely efficient, for example a golf ball sized lump of uranium can fuel a nuclear powered submarine for 13,700 leagues or 66144 kilometres. Uranium-238 has a half-life of 4.5 billion years and makes up 99 percent of the total amount of uranium on the earth. I cant explain the process of nuclear reactors in one small paragraph so Ill just say that heat from the uranium is used heat water, create steam, and that steam spins turbines. So what do you think about coastal wind farms? Are you all for them, unsure, or completely against them? Well these wind turbines have caused a real uproar and this project of coastal wind farms havent adapted to the public as the government thought they would. Its now staring to look as though its been more trouble than what its worth. The Victorian government has designed on installing 2000 megawatts of energy production by 2010, which is the equivalent of 1200 to 1500 wind turbines. There are at present 27 operating wind turbines in Victoria, 14 at Codrington near Warrnambool, 1 on the Bellarine Peninsula, and 12 at Toora here, in South Gippsland. Each turbine stands between 100-130 metres tall, the equivalent of a 35-40-storey building, and the next generation is said to be even bigger. This sounds good, positive, its clean and renewable energy, pollution free, but it was where the turbines were to be placed that outraged the public. They were to be placed overlooking some of our most pressured landscapes on our coasts, like Wilsons Promontory, The Great Ocean Road at Nirranda, The Bay of Islands, Discovery Bay, Cape Bridgewater, Logans Beach, Corner Inlet, Bald Hills, and Kilcunda Coastal wind farm projects have become a problem as they have already, and will continue to have a devastating visual impact on our beautiful coasts, ruining the natural landscapes that values Australias Coastline. The sight of our coastlines has been obscured by these giants and is said to be industrialising our coast, which is hypocritical. As much as the coastal communities are fighting for their coast to stay the way it is, the government doesnt seem to be listening. This is only one disadvantage of these coastal wind farms, as there are many difficulties that have contributed to these projects. Another complaint is that wind farm developments could actually wipe millions of dollars from Victorias coastal property market, which has already occurred of up 30%. Landowners within 2 kilometres of Toora Wind farms have struggled desperately to sell their properties, and those who found buyers had to sell well below the market price. This price is also expected to drop even further if more wind farm developments near the coast start to take off like the expected wind farms near Cape Liptrap, which is said to have devastating effects on land values and its scenery. The noise factor is another problem, which has been an issue after some of these developments. People have been forced to abandon their dream homes from the coasts because of the tremendous noise of these wind farms. Mr. Stephen Garito, who said he had to leave his peaceful country lifestyle because of the low frequency, humming noise that is generated by the blades as they pass the towers and high speeds, which he said, created a similar effect to nightclub music. It was like a disco beat coming from a few blocks away rising and falling all day and all night. Even with all the windows and blinds shut, it still didnt stop the irritating noise, making them unable to sleep at night. The glare from the rotating blades was also a major turnoff for prospective buyers, and they complained as the flicker was worse than noise and drove you crazy. There was also the cost issue of establishing a wind farm development as each turbine would cost approximately $2.8 million (Australian) to be inst alled, therefore a 40-turbine wind farm would cost around $122 million. That was the bad side of this situation, and believe it or not there is also a good positive side and some advantages to be had with these wind farm developments starting with electricity. A modern 1.75 MW will produce approximately 5 million kilowatt hours of generation per year, which is equivalent to the annual electricity consumption of 900-1000 Victorian households. Wind farm energy is also a renewable resource of clean pollution free energy. Electrical energy is essential to billions of people around the world as we rely on it for the simplest things like light to read and water for the shower, but the conventional sources of power come from burning fossil fuels such as coal, gas, oil, or from nuclear fuels. Apart from the fear of fossil fuel shortages, they are destroying our planet and changing the climate, which has warmed by about 0.7 degrees Celsius in the last 300 years and about 0.5 degrees Celsius of that warming occurring in the last 100 years, which is a great concern . This change is due to the increase in the emissions of greenhouse gases, which these burning fossil fuels have created and scientific models predict that the average global temperature will rise by a further 3 degrees Celsius by the next century, unless change takes place now. With the global temperatures changing, this is also leading to the ice caps in the artic and Antarctic waters already melting, which is leading to sea level rises. The result of this on human and natural environments could be devastating as rising sea levels could submerge whole islands, flood low lying areas in many countries and without doubt push entire species to extinction. An alternative generation of clean energy source like wind farms are a growing importance and a global priority for future generations, as a modern 1.75 MW wind turbine would annually displace approximately 7,000 tonnes of carbon dioxide from other electricity sources. There is also the fact that jobs will be created through wind farm developments including coastal wind farm developments of about 30-50 local jobs during construction, and atleast 5 permanent jobs for operation and maintenance. As the supply of wind farm energy is greater then electrical energy, and depending on the normal economic theory, electrical prices will drop and the power quality should increase. The best advantage of coastal wind farms apart from the general advantages above is that wind turbines can actually be placed on concrete pillars in the water off the shore. So unlike wind farms inland, which still leaves more than 97% of the land its situated on for farming and grazing, these coastal wind farms wont ruin views and sceneries as they will hardly be seen. At Port Phillip, Western Port and Corio bays, 300 wind turbines are planned to be erected across these bays by the Nepean Wind Energy Company. The 140 metre high, 54 metre long bladed turbines are said to be built in water depths of up to 25 metres outside shipping lanes and away from areas with significant bird population. The facility could produce almost half of the State Governments target for wind energy in a single project, and the company claims the project will result in a reduction in the states output of greenhouse gases by 1.8 million tonnes and provide enough power for 260,000 homes. These wind farms will also allow energy users in Melbourne and Geelong to contribute to producing pollution free energy and it is said that A project of this scale has the potential to give Melbourne an iconic and sustainable feature.

buy custom Medicinal Marijuana essay

buy custom Medicinal Marijuana essay For thousands of years, marijuana has been used as a prescription for many sicknesses. Presently, it is still used in various states for therapeutic purposes. The medicinal use of marijuana is surrounded by a cloud of social, political, and religious debate, which obscures the facts that should be believed in its treatment. The issue of whether we should legalize marijuana to be a medical option has been widely debated in our community recently. It is an important issue because it concerns the health of the populace at large. This essay considers the arguments against legalizing medicinal marijuana and points to some of the valid reasons for the opposed views. It then puts forward arguments for legalizing medicinal marijuana and the reasons for the proposed views. The controversy surrounding marijuana stems from the legalization of the drug for medical use. Outrageously expressive arguments rage about whether or not marijuana should be considered as a legitimate medicine. The present debate over the medical use of marijuana is in actual fact, a debate over the worth of its medicinal properties relative to the risk posed by its use. But should marijuana be a medical option? Even though scientists and supporters propose for its medical usage, I believe that marijuana should not be used as a medical option. In the 20th century, marijuana has been used more for its ecstatic effects than as a medicine. Why should doctors take a solid stand against the legalization of marijuana? First, marijuana is recorded as Schedule I in federal drug laws, which means that it has no lawful medical use. Second, no medical authority identifies it as an effective treatment for any condition. It may bring some easing effects on patients with extensive list of diseases, medical conditions or symptoms, but scientific evidence is absent. However, it would be extremely unlikely that a responsible physician would prescribe a joint of marijuana to treat depression. The instant danger is that sick people will use marijuana in lieu of authentic medicine; the symptoms will be camouflaged by the psychoactive effects of the drug causing the patient to return to legitimate treatment whilst the time period for treatment has really elapsed. Thirdly, marijuana use has many severe health effects as detailed in the subseque nt paragraphs (McCollum 127). Scientists have confirmed that smoked marijuana, damages the lungs, heart, brain, and immune system. It impairs learning and impedes with judgment, memory and perception. Research has been accumulating lately indicating clearly that marijuana limits the capacity to absorb and preserve information. A 1995 study of college students ascertained that the inability of heavy marijuana limits users to focus, prolong attention, and systematize data for as long as twenty four hours after their last utilization of the drug. Earlier research that compared cognitive capability of adult marijana users with non-using adults, found that marijuana users fall short on memory as well as mathematics and oral skills. Although it has yet to be confirmed conclusively, that heavy marijuana use can cause permanent loss of intellectual capacity, animal studies have confirmed that marijuana damages portions of the brain vital to learning and memory. Mental disorders associated with marijuana use has been recorded in the Diagnostic and Statistical Manual of Mental Disorders (DSM) IV and issued by the American Psychiatric Association. These include Cannabis Intoxication Delirium, Cannabis Intoxication, Cannabis Induced Psychotic Disorder, and Cannabis Induced Anxiety Disorder (Golden, Peterson and Haley 63). Marijuana is a hazardous mind-altering drug and is the cause of many mental disorders, including panic attacks, delusions, acute toxic psychosis, flashbacks, depression, depersonalization, uncontrollable aggressiveness, hallucinations, and paranoia. Moreover, for a long time marijuana has been well-known to trigger attacks of mental illness for instance, schizophrenia and bipolar psychosis. In the short term, use of marijuana weakens thinking, perception, learning, memory and judgment. Many physicians have opposed medicinal marijuana since it would increase users and lead to subsequent increases in addiction (McCollum 126). Moreover, smoked marijuana contains cancer-causing compounds and has been involved in a high percentage of crashes and workplace accidents, since, its consequence on coordination, perception, and judgment means that it consequences result to a number of accidents. Marijuana is also associated with gateway behavior leading to more extensive drug use. Currently, there are no controlled studies of marijuana in the AIDS-wasting disease, nor have there been any logical studies of the effects of smoked marijuana on immunological condition in HIV patients. Smoking marijuana has also been correlated with other medical problems. Rapidly accumulating new research has revealed that babies born to women who smoked marijuana during pregnancy have a heightened prevalence of leukemia, low birth weight and other newborn defects. Furthermore, smoking marijuana may compromise ones immunity. In patients with AIDS, marijuana use has been a contributing factor on the heightened growth of both fungal and bacterial pneumonias. Moreover, among HIV positive individuals, marijuana use has been revealed to be a causal factor for the rapid shift from HIV infection to AIDS and the acquirement of opportunistic infections or Kaposis sarcoma, or both (Jamerson 59). Additionally, chronic marijuana smokers are susceptible to contracting bronchial asthma, emphysema, bronchitis, chest and colds. Persistent usage damages the lungs and airways and increases the risk of cancer. There is a high rate of exposure to cancer-causing chemicals from smoking a single marijuana joint to ssmoking five tobacco cigarettes. Moreover, there is proof that marijuana may restrict the ability of the immune system to fight disease and infection. Marijuana also affects hormone since regular use can delay the onset of puberty in young men and lessen sperm production. For women, regular use may interrupt normal monthly menstrual cycles and reduce ovulation. When pregnant women use marijuana, they run the possibility of having smaller babies with lesser birth weights and a high possibility to contract health problems (McCollum 127). The legalization of medical marijuana has been the desire of many citizens in United States for a long time. Supporters and scientists of this view claim that for many critically sick people, medicinal marijuana is the only remedy that relieves their pain and suffering, or treats symptoms of their medical situation, without debilitating side effects. Moreover they argue that marijuana should be relied on since it is valuable and scientifically attested. Supporters also claim that marijuana may be effective in the treatment of pain, nausea resulted consequence of chemotherapy, and weight loss related with AIDS and cancer. They also maintain that marijuana-derived chemicals may improve sleeping problems, MS-related pain, bladder problems and mobility difficulties. Doctors also recommend medical marijuana for easing pain and improving the quality of life for patients who are terminally ill. They also recommend it for other diseases such as multiple sclerosis, insomnia, ADHD, inflammation, epilepsy, glaucoma, chronic pain, migraines, loss of appetite, anxiety, arthritis and Crohn's disease. Opponents of marijuana put forward these ideas because they believe that marijuana is the safest drug with real benefits for the user as compared to alcohol which is unsafe and causes birth defects, addictions, and involves factually every organ in the body (Jamerson 59). However, after hundreds of reports, experiments and studies, there is still no consensus about its medicinal effect. Even though various findings hold that marijuana holds medical value in the treatment of various diseases, it is still illegal for doctors in U.S. to prescribe their patients with marijuana. There is still little evidence that marijuana has medical efficacy. The medical use of marijuana should be supported by scientific evidence rather than ideology. Hence, science and medicine should conclude the question of whether marijuana has any legitimate medical use (McCollum 126). In Conclusion, there are valid reasons why marijuana should not be a medical option. Americans have the right to disagree on the legalization of medicinal marijuana, since it is not safe for medical use. The risks to individuals and the costs to society associated with medicinal marijuana are substantially high. Hence, making an exception for marijuana would create a dangerous precedent in our country at large (McCollum 129). Buy custom Medicinal Marijuana essay

Organization and Management Essay Example | Topics and Well Written Essays - 2000 words

Organization and Management - Essay Example Scientific management, in contrary, was from Fredrick Taylor in the year 1911. In a more simple term it is said to be amongst the best ways duties could be executed and the best method to use in improving the methods or techniques employed by employees (Robbins p.38) A bunch of comparisons have been done for the two methods of management, for instance specialization, fragmentation and mechanization of work. Moreover, inadequate skilled and intellectual content will hasten the current work. Mechanization of fordism’s big production further stressed a number of Taylor’s accepted beliefs of management being separated from human emotions and affairs, applying ‘humans as instruments or machines to be manipulated by their leaders’ (Hersey p.84). There was emphasis and blending by Fordism for scientific techniques to have things done according to Ford’s flourishing process of mass production. There were differences between the two methods of management. For dism dehumanized employees while the other method persuaded the employees that their objectives could be easily achieved together with their employees’ goals, thus they should strive towards this direction. Ford’s method was appropriate for firms that participated in huge production, unlike scientific management method that could be employed by many firms. Big companies like Ford motors put these methods in practice. The two theories of management show companies on what technique of management they should employ today. Employers should know that their employees should be treated fairly with democracy. Since 1970’s, wide changes in technology and market have made employers and producers to employ greater diversification in production and more flexibility in production methods. Movements in the direction of a flexible organization became apparent. For instance, organizations like Toyota, NASA and Nissan act as contemporary examples of Fordism and portray movements to the direction of scientific management. Similarities that are there between the two theories are Fordism’s mass production mechanization and Taylor’s efforts of using workers like machines. Fredrick planned this by the use of management principles that included science development for every element and looking for the fastest method the responsibility could be executed. Ford’s best kinds of his production system was inclusive of dedicated and fixed machine use in individual’s duty, rather than making workers machines (Hollinshead, 1995). As Taylor tried to show the globe that science existed in management and the fastest way was a better way, he pointed out incompetence in managers for being inefficient in running of factories and railroads. Using motions and time studies, Fredrick attained increased production of up to twice the injection (Dunphy, 1998, p.4). Taylor’s thoughts were answered by others: at a 1910 ICC hearing, Brandeis reiterated that America’s railroads was in a position to save 1 million dollars in a day in case they adopted scientific management method in their operations (Oakes, 1996).Fredrick Taylor proved to the globe that the scientific and methodical study of duty or work could end up with an improved effectiveness. He believed definition of clear guidelines for employees would improve the goods production. Fordism just like

The evil-god challenge Essay Example | Topics and Well Written Essays - 1500 words

The evil-god challenge - Essay Example These two notions are a measure by which human lives are evaluated. Depending on the actions of a person he or she may have a reputation of a good or a bad one. From early childhood, while listening fairy tales we begin to learn the concept of good and evil. We are taught that good always wins, though it is not so in the reality. Then the concept of God enters the life of children and they fully believe in what is written in the Bible, that is, the existence of the Lord is doubtless as well as the good nature of his personality and actions. Still there is a hesitation whether God exists and what his essence. So let’s consider this question with the help of research of theistic works on the theme of Stephen Law and Theodore M. Drange. To begin with we will study the argument of Law’s â€Å"The evil-god challenge† in which he touches the aspect of the good or evil will of the Lord who has the power to control life on the Earth as he is its Creator. From the beginning to the end of his work Law doubts the good motives of God’s activity for he allows so much suffering for his creatures, people. One of the main reasons of such a situation, according to the author, is that through the way of travails humans can become stronger and recognize good with even greater intense. Furthermore, the Lord has gifted people with an option of good or evil so it depends on them which one to prefer. And it is God who has allowed evil to exist by his decision not to made humanity his puppet theater giving it the opportunity to make a choice in favor of evil. Law claims that the explanation of such phenomenon as natural disasters which destroy and cripple the lives of sentient inhabitants is His will to prevent a g reater tragedy that is invisible for people. This is the first-order evil which needs the second-order good (theodicy) as a world’s virtue, for example. In this respect the suspicion or hypothesis of evil god arises. People just don’t understand how can a good

Performance Evaluation and Enhancement of Mobile Node: MIH

Performance Evaluation and Enhancement of Mobile Node: MIH PERFORMANCE EVALUATION AND ENHANCEMENT OF MOBILE NODE USING MIH CHAPTER 4 NETWORK SIMULATOR 4.1 Introduction NS2 is associate open-source simulation tool that runs on Linux, its a discreet event machine targeted at networking analysis and provides substantial support for simulation of routing, multicast protocols and informatics protocols, like UDP, TCP, RTP and SRM over wired and wireless (local and satellite) networks. Its several blessings that build it a great tool, like support for multiple protocols and therefore the capability of diagrammatically particularization network traffic. In addition, NS2 supports many algorithms in routing and queuing. Local routing and broadcasts are a part of routing algorithms. Queuing algorithms embody honest queuing, deficit round-robin and FIFO. NS is associate object oriented machine, written in C++, with associate OTcl interpreter as a frontend. The machine supports a category hierarchy in C++ (also referred to as the compiled hierarchy during this document), and an identical category hierarchy inside the OTcl interpreter (also referred to as the taken hierarchy during this document). The 2 hierarchy’s square measure closely associated with every other; from the user’s perspective, theres a matched correspondence between a category within the taken hierarchy and one within the compiled hierarchy, the basis of this hierarchy is that the category Tcl Object. Users produce new machine objects through the interpreter; these objects square measure instantiated inside the interpreter, and square measure closely reflected by a corresponding object within the compiled hierarchy. The taken category hierarchy is mechanically established through strategies outlined within the category TclClass. User instantiated objects square measure reflected through strategies outlined within the category TclObject. NS2 is extensively utilized by the networking analysis community. It provides substantial support for simulation of communications protocol, routing, multicast protocols over wired and wireless (local and satellite) networks, etc. The machine is event-driven and runs in a very non-real-time fashion. It consists of C++ core strategies and uses Tcl and Object Tcl shell as interface permitting the computer file (simulation script) to explain the model to simulate. Users will outline arbitrary network topologies composed of nodes, routers, links and shared media. A chic set of protocol objects will then be hooked up to nodes, sometimes as agents. The machine suite conjointly includes a graphical beholder referred to as network animator (NAM) to help the users get additional insights regarding their simulation by visualizing packet trace information. NS is an occasion driven network machine developed at UC Berkeley that simulates style of informatics networks. It implements network protocols like communications protocol and UPD, traffic supply behavior like FTP, Telnet, Web, cosmic microwave background and VBR, router queue management mechanism like Drop Tail, RED and CBQ, routing algorithms like Dijkstra, and more. NS conjointly implements multicasting and a few of the mac layer protocols for computer network simulations.    4.2 A Short History   NS2 started as a variant of the $64000 network machine in 1989 (see Resources). REAL could be a network machine originally supposed for the real the dynamic behavior of flow and congestion management schemes in packet-switched information networks. NS2 is associate degree object-oriented machine developed as a part of the VINT project at the University of American state in Berkeley. The project is funded by government agency together with XEROX Palo Alto research center (PARC) and Lawrence Berkeley National Laboratory (LBNL). NS2 is accessible on many platforms like Linux, Ubuntu, FreeBSD, SunOS and Solaris. NS2 conjointly builds and runs underneath Windows. Large scenarios benefit from large amounts of memory. Additionally, NS2 requires the following packages to run these scenarios Tcl has released Tcl8.3.2, Tk has released Tk 8.3.2, OTcl has released OTcl 1.0a7 and also TclCL has released TclCL 1.0b11. 4.3 C++ and OTCL Duality In this means, the controls of the C++ objects area unit given to OTcl. It’s conjointly attainable to feature member functions and variables to a C++ connected OTcl object. The objects in C++ that dont have to be controlled during a simulation or internally utilized by another object dont have to be connected to OTcl. Likewise, associate degree object (not within the information path) is entirely enforced in OTcl. Fig 4.1: C++ and OTcl: The Duality In this means, the controls of the C++ objects area unit given to OTcl. It’s conjointly attainable to feature member functions and variables to a C++ connected OTcl object. The objects in C++ that dont have to be controlled during a simulation or internally utilized by another object dont have to be connected to OTcl. Likewise, associate degree object (not within the information path) is entirely enforced in OTcl. Figure 5.1 shows associate degree object hierarchy example in C++ and OTcl. One factor to notice within the figure is that for C++ objects that have associate degree OTcl linkage forming a hierarchy, theres an identical OTcl object hierarchy terribly just like that of C++. NS was inbuilt C++ and provides a simulation interface through OTcl, associate degree object-oriented idiom of Tcl. The user describes a constellation by writing OTcl scripts, so the most ns program simulates that topology with mere parameters. The NS2 makes use of flat earth model within which it assumes that the atmosphere is flat with none elevations or depressions. But the real world will have geographical options like valleys and mountains.NS2 fails to capture this model in it. Many researchers have planned the additions of latest models to NS2.Shadowing Model in NS2 makes an attempt to capture the shadow impact of signals in real world, however will that inaccurately.NS2s shadowing model doesnt think about correlations: a true shadowing impact has sturdy correlations between 2 locations that area unit near one another. Shadow attenuation ought to be sculptured as a 2 dimensional log-normal random method with exponentially decaying spacial correlations. 4.4 Screenshot of Network Animator Fig 4.2: Network Animator Window NS animator window is shown in the above figure 4.2 which can be used to view the connection between the mobile and the network towers, it shows the movement packet drops which take place during simulation. 4.5  NIST’s Media Independent Handover module 4.5.1  Introduction Wireless network types Handover are off two types, Horizontal handovers also called Homogenous Handover and Vertical handovers also called Heterogeneous handovers. If Handover take place in same access technology (WiFi WiFi) or (WIMAXWIMAX) is Horizontal and if Handover takes place within the different access technology (WiFi WiMAX) or (WIMAXWIFI) is Vertical Handover. If Longer the handover duration, then higher the packet drop and poor QoS [7]. IEEE with 802.21 MIH addressed vertical handover, which separates the different access technology in a mobile device from the upper layers in the protocol stack. NIST has provided the 802.21 MIH add-on modules [3] for network simulator (ns2.29). These module support the two of the MIH functions, events and commands. 4.5.2  Supporting Technologies of 802.21 in ns-2 Ns-2.29 supports the access technologies in IEEE 802.21 scenarios are: WiMAX (802.16), Wi-Fi (802.11), UMTS and Ethernet (802.3). 4.5.3  Implementation of Nodes with Multiple Interfaces in ns-2 NS-2 does not support the heterogeneous multiple interfaces of a mobile node (MN), because node structure do not necessarily follow the same as the one defined in the basic model by external packages. Hence to resolve this issue, NIST add-on module created the concept of multiFace node also called super node, which is a mobile node which can links to other mobile nodes, these interfaces for the multiFace node, and the multiFace node can be viewed as as â€Å"supernode†. This concept is illustrated in Fig. 4.1. Fig. 4.1: High Level View of MultiFace Node Fig. 4.2: Power boundaries defined in NS2 The interface nodes activate the events and forwards them to the super node. The MIH Users on the super node are often ready to register and to receive these events. 4.5.4  Power Boundaries are often outlined in Wifi and WiMAX Cells In order to spot power boundaries which may be utilized in the simulation, 3 variables are outlined in ns-2.29, that is shown in Fig. 5.2. Theses variable are often outlined as: †¢CSTresh: accustomed outline the minimum power level to sense wireless packets and conjointly switch the mac layer, if mac layer is idle then it are often switched to busy, †¢RX Tresh: are often accustomed outline the minimum power level to receive wireless packets with error free; †¢pr_limit: are often perpetually equal or superior to one and is employed within the equation (RX Tresh) * (pr_limit), then this equation are going to be shaping the minimum power level that Associate in Nursing interface senses Link taking place event before triggering. In the above figure Fig 4.2, shows the ability boundaries between WLAN and WiMAX base station with its vary wherever the highest most layer is Cs thresh_, middle layer is rx thresh_ and also the inner layer is rx thresh_ * pr limit_. Dept. of CSE, VKIT 2014-20151 Education and Fertility | Literature Review Education and Fertility | Literature Review The relation between the education and fertility of women is a topic that has received much attention in the last decades. Some scholars have found that there is an inverse relation between the education and fertility, however, it is still unknown if this relation is causal or not. But in general, across countries, when women acquire more education, this decreases the number of children. The spread of education around the world has been linked to decreases in fertility that incremented women rates of enrollment and completion of secondary education. In point of fact, women with secondary education have on average one less child (Leà ³n, 2004). When estimating the relationship between education and fertility there are unobserved characteristics that affect schooling preferences and are correlated with unobserved variables that encourage to have a child or not. To better clarify this criteria, we have to analyze the next example. When a woman has wishes to work, attend college, make a professional career, this will impact negatively the number of children that she wants to have. On the contrary, women with access to the credit market, are more likely to have more years of education and also to children. As we observe, there is no only a negative relation between fertility and education, but it also may be positive (although is not common). In addition, when analyzing the effect of education on fertility we have to take into account the welfare policy consequences. When the total fertility rates decreases and the life expectancy increases, this may cause an ageing of the population. Therefore, the ratio of retirees to working-age adults increases and this create a serious problem on spending of governments on health care and pensions. This is the case of developed countries. By the contrary, in developing countries (specially Latin American countries), when the total fertility rate decreases, the risk of health between women and children decreases leading to a improvement in the welfare conditions. In the recent years, programs such as the World Banks Female Secondary Schooling Assistance Project seek to motivate the education of women around the world. Given these facts, the hypothesis than education affect fertility levels of women is valid. Not only the education of women affect their fertility rate, but also the marriage, which is delayed because women desires to enter to the labor market or to increase their education. The theoretical aspects concerning to the relation of fertility and education is very broad. In order to explain this relation with more accuracy it is important to analyze the studies of Barro and Becker (1988), Livi-Baci (1997) and Willis (1973). They agree in the fact that women with more education diminishes their fertility because of the increment in the cost of opportunity of time. Other models point out the wage of women as the main factor in explaining the cost of opportunity of childbearing. Montgomery and Trussel (1986) analyze the children as normal goods. Here and increment in the education of women produces an increment in the parents income, which lead to an increment in the spending of normal goods (children), dominating the wage effect. It is also important to analyze the models that explain the fertility as stochastic processes (Wolpin (1994), Newman (1988) and Hotz and Miller (1988), however, this studies have no provided any result about the empirical specification for the life cycle fertility. They just agree in the fact that the returns of more years of education are positive and that this produces an inverse relation between education and fertility in women. Reviewing the literature between education and fertility, we have to highlight the contribution of the studies done by Becker. Becker (1960) and Becker and Lewis (1973) analyze the child quality fertility model, which is one of the most used model in explaining the relation between education and fertility. This model analyze the role of income of parents in the quality and quantity of children. That is to say that when the income of parents increases, the quality and quality of children also increases. Becker argues that the income elasticity of the quantity of children is small related to the income elasticity of the quality of children. Given the fact that the spending on children increases, it leads to a prevalence of the higher quality. In this case, the substitution effects subdue to the income effect. Following this criteria, Easterlin and Crimmins (1985) formulates the theory of the demand of children, referring mainly to the desired family size of parents but taking into consideration that the knowledge of birth control instruments is general and does not imply any cost. Moreover, the supply of children refers to the quantity of children that parents would experience, without limiting the family size. As we can observe, all the theories mentioned above deal with the negative relation between fertility and education, just with the exception of the supply theory that connects the health and the fecundity. Therefore the role of education is very important given the fact that help women to have more knowledge about contraceptive methods, and gain different perspectives of life. In addition, according to the economic theory, the relation of education and fertility has consequences for the welfare policies of the countries. An analysis in Developing Countries The fertility rate has decreased in Latin American countries through the years. According to Weilti (1993) the industrialization and modernization have been drivers in this reduction. On the one hand, with the industrialization the technology, communication, infrastructure and transport was improved. On the other hand, modernization has had a greater impact on fertility, improving of health care, education, urbanization. The arguments in explaining the decrement in fertility are mainly two: gender equality and education of women. Gender equality refers to the control of women on their lives (in all aspects) and education promote all of this independence of women. In recent years the inquiry about if educated women are selected for additional features that could be related to lower fertility such as income, earning of husband has brought lot of discussion. All of these additional features including on the analysis appears to be as indicators of a negative relation between fertility and education. Also it is important to mention that the autonomy of women is an important aspect when decreasing their fertility (Dyson and Moore, 1983). This implies that educated women has more independence in taking decisions in their life ((Basu (1992); Morgan and Niraula (1995); Vlassoff (1996)). The literature about the negative relation between fertility and education is very broad. Currently, there is lot of discussion about the reduction on mortality and the increasing aspirations from the women as main factors in explaining this relation. The decrease in fertility according to demographers is explained by reductions in infant and child mortality. The increasing aspirations of women is another important factor in explaining the negative relation between education and fertility. This model, that relates the decreasing in fertility levels with the increasing in aspirations of women, tries to explain mainly the resources in the market that women spend in children and in goods and this decision on how much to spend in each thing depend on preferences of women. According to the DHS survey carried out in the 80s, one of the most powerful tools of fertility is the access to mass media in developing countries, especially when talking about contraceptive methods and family size. The access to mass media it is really important in the family planning of households. But according to some authors as (Ramesh et al. (1996, Westoff and Rodriguez (1995) the education should increase along with the increase of the material aspirations. As reductions in fertility (at macro-level) are given by increments in educational, we expect that education has a connection with rising aspirations (United Nations, 1995). In fact, in South Asia, accoring to Basu (1999), the decrease in fertility is linked to increments in dowry. As we can observe, the relation between education and fertility seems to be explained with the theory about material aspirations of women. Following this theory of the material aspirations of women, we come to the conclusion that the increment in material aspirations and more investments in the schooling of daughters can provoke a decline in fertility in the couple. The impact on Latin American Countries According to the International Family Planning Perspectives, 21:52-57 80, 1995), women that have no education have on average bigger families of 6 or 7 children, while women that have education 2 or 3 children. The knowledge about contraceptive methods is more favorable to educated women (Demographic and Health Surveys for 9 Latin American countries). It is important to point out that the negative relation between education and fertility stopped being as an automatic progress after the World Fertility Survey in the 70s when the results gave a broader idea that the fertility reductions are explained by the development, gender stratification of the society. The impacts of education on fertility can be explained for the following aspects. In first place, the education acts as a source of knowledge, given the fact that schooling improves the knowledge of women about different lifestyles and a major access to information about fertility elections. Secondly, education is a tool for the development of a country. The education is a cover letter to entry formally to the labor market. And finally the education acts as a transformer of attitudes, specially aspirations in life. It is known that Latin American is the most unequal society in the world. The gap between the rich and poor people has increased in the last years and this situation seems to not come to an end. In some Latin American Countries the access to a good education is given mainly by the social origins. Not always, but in most of cases, poor people has no access to an education because of the lack of money and opportunities. But this situation has improved in the last decades with the free access to public education and improvements in the literacy rates of Latin American Countries. However, in countries such as Guatemala, 42% of women have no formal education (Indicators of female educational attainment in Latin America, by country, 1985-1989). As we observe in the table below, the 1/5 of the people in Bolivia and El Salvador has no education, which is a extremely bad indicator. In the rest of the Latin American countries the years of schooling show a better performance, reaching 10 years of education roughly. As we mentioned above, the improvements in education has been a major concern in Latin American Governments in the recent decade. As we observe in the table, countries such as Colombia, Peru, Ecuador, Dominican Republic and Mexico has showed substantial progress in the school attendance (1.4, 1.7, 1.4, 2.2. and 3.4 years respectively). The relation between fertility and education in Latin American is considered as the most powerful in the world. This is explained by the differential in reproductive strategies inside this society. If we refer to pretransitional societies, the behavior of women with no education is similar to the one of that societies, having on average 6 or 7 children, while women with better education have on average 2 or 3 children. In table 2, there is a surprising fact in which the fertility patterns (desired family size) are almost the same among poor (educated) women and educated women, but in practice they differ a lot. Referring to the contraceptive knowledge, here we find a big difference. The difference between uneducated and educated women in Colombia and Dominic Republic is 20% and 40% in Bolivia, Ecuador, Peru and Mexico.

Honor :: College Admissions Essays

A Question of Honor Since my most important objectives in life are growing in my relationship with God and becoming a respected man of irrefutable integrity, I find that my lifestyle complements the moral expectations and responsibilities required of cadets attending the United States Air Force Academy. My parents have instructed me in principles that closely parallel the Academy's Honor Code, and I have chosen to integrate those into all aspects of my lifestyle. Without a doubt, I will not experience any difficulty adopting the Honor Code as a way of life for I currently practice this and will continue to do so. In fact, I am pleased that the Academy requires moral excellence of "tomorrow's Air Force leaders" for this is precisely the type of leader I desire to become. The basic morals and principles, such as contained in the Honor Code, are being disregarded and shunned in overwhelming numbers by our country. An especially visible example is today's political arena. A large percentage of the American public considers politicians and elected officials to be corrupt and selfish. Politicians spurred on by greed become dishonest to escape a potentially embarrassing situation, to win an election, or to take advantage of an unsuspecting constituent. As a result of these publicized events, politicians everywhere have acquired a poor reputation and an even worse public image. By no means am I saying that this is characteristic of all politicians. However, as top government officials and representatives of our nation, politicians, elected officials, and leaders should set a moral example. In order to restore their reputations and rectify any past dishonorable actions, it would behoove all politicians to live a lifestyle that is consistent with the United S tates Air Force Academy Honor Code. Then, as they become men and women of character, they will earn and receive the respect of the American people.

Ethical Challenges Essay

Almost any field of profession has its corresponding hardships that an individual involved in it has to face. Nevertheless, there are occupations that pose a more challenging situation due to the fact that it deals with the life or personal affairs of other people. This kind of adage is greatly applicable to the area of psychology most specifically counseling. The counselors are responsible in aiding people who are having difficulties in various areas of their lives, may it be in terms of their personal growth, relationships with other people, and many others (Hawkins et. al, n. d. ). Being the case, counselors have their own set of ethical dilemmas in doing their responsibilities especially in terms of separating their personal and professional relationships with their clients as well as giving sound judgments in times of crucial situations. These aforementioned roles could be exemplified in this case of a counselor that works in a rural setting. Counseling in this type of area entails that almost all people know each other and that they usually go and socialize to the same places. As such, being a counselor it could not be prevented that I have to socialize with my clients to some community events. This could mean ethical dilemmas such as: confidentiality, privacy and the overall boundary between a counselor and his or her client. This is why I should establish a firm distinction between my personal and professional life. I should see to it that whenever I mingle with my clients at community events I would not discuss any of the sessions that we had especially the situation of my other patients. Moreover, it is better that I do not get to attach with any of my clients to prevent any biases in their cases but I will still make sure that I establish good relationship with them. Another case involves a counselor that works in a local high school. One of her clients called her at a very distraught state and informed her that she was pregnant before and she committed abortion. She has not told anyone about it aside from the counselor. If I were the counselor, I will tell my client that it would be better that we talk the problem over face-to-face rather than in the phone. I could fetch her, as she is not in a proper state to travel. Then, we could talk at the clinic regarding her problem. I will also make sure that utmost confidentiality is observed since this is a very serious and delicate matter. I would leave the decision to her as to when she would inform her family and her boyfriend about that particular incident. However, I would also make sure that I inform her about the limitations to confidentiality (Hawkins et. al, n. d. ). In doing so, I could aide in deciding for the appropriate thing to do. The ethically appropriate action is to aide her through counseling and other means to guide her in making the right choices but I will never meddle with her decision or impose anything upon her. The role of the counselor is to help and guide the patient to make her burden easier but never to take control of the situation. In these two cases, it is clearly observable that counselors face ethical challenges in their profession. They even encounter more incidents like these because their responsibilities deal with other people’s life especially with regards to their emotional state. As such it is important that counselors adhere to ethical standards in order to help them in making sound and appropriate decisions. Reference Cornier, & Hackney. (2008).
