Title The Contenders For The Presidential Election Of 1856, The Democ

Title: The Contenders For the presidential election of 1856, the Democrats nominated James Buchanan and John Breckenridge, the newly formed Republican party nominated John Fremont and William Drayton, the American [or Know-Nothing] party nominated former president Millard Fillmore and Andrew Donelson, and the Abolition Party nominated Gerrit Smith and Samuel McFarland. Buchanan started his political career as a state representative in Pennsylvania, was elected to the U.S. House of Representatives in 1821, appointed minister to Russia in 1832, and elected US Senator in 1834. He was appointed Secretary of State in 1845 by President Polk and in that capacity helped forge the Treaty of Guadalupe Hidalgo, which ended the Mexican War. He was appointed by President Polk as minister to Great Britain in 1853. As such, he, along with the American ministers to Spain and France, issued the Ostend Manifesto, which recommended the annexation of Cuba to the United States. This endeared him to southerners, who assumed Cuba would be a slave state. He was one of several northerners supported over the years by southern Democrats for being amenable to slaveholders' interests, a situation originating with Martin van Buren. Buchanan's two major rivals for the nomination, Franklin Pierce and Stephen Douglas, were both politically tainted by the bloodshed in Kansas. Buchanan was untainted, since he had been abroad during most of the controversy. Even so, he did not secure the nomination until the seventeenth ballot. Fremont was best known as an explorer and a war hero. He surveyed the land between the Mississippi and Missouri Rivers, explored the Oregon Trail territories and crossed the Sierra Madres into the Sacramento Valley. As a captain in the Army, he returned to California and helped the settlers overthrow Mexican rule in what became known as the Bear Flag Revolution, a sidebar to the Mexican War. He was elected as one of California's first two Senators. The infant Republican party was born from the ashes of the Whig party, which had suffered spontaneous combustion as a result of the slavery issue. The party's convention was a farce; only northern states and a few border slave states sent delegates. Sticking to their Whig roots, they nominated a war hero, albeit a minor one. William Drayton's runner-up for the VP slot was Abraham Lincoln. Fillmore, having been the thirteenth president following the death of Zachary Taylor, found himself representing the American party after many northern delegates left the convention over a rift caused by the slavery issue. Their objection was that the party platform was not strong enough against the spread of slavery. The party's vice presidential nominee was a nephew of Andrew Jackson and the editor of the Washington Union. The party, also known as the Know-Nothings, was extremely antagonistic towards immigrants, Catholics and other assorted minorities. The party was born in 1850, when several covert "N ative American" societies joined together, their secret password being "I know nothing." Smith was nominated by the Abolition party in New York, which had nominated Frederick Douglass for New York secretary of state the year before under the label New York Liberty Party. The Campaign: Neither Buchanan nor Fremont campaigned themselves. Republicans declared Buchanan dead of lockjaw. Fremont, however, had a splendid campaign substitute, his beautiful wife Jessie, prompting "Oh Jessie!" campaign buttons. The Democrats tried desperately to avoid the slavery issue altogether, opting instead to pursue the conservative effort to preserve the Union. The Republicans, on the other hand, actively attacked slavery. Their campaign slogan was "Free Soil, Free Men, Freedom, Fremont". [Shields-West, pgs 78 The self-serving efforts of Stephen Douglas did more to mold the campaign of 1856 than did any other single event. Although he did not intentionally destroy the North-South balance create d by the Compromise of 1850, his focused quest for the White House caused him to make some foolish choices. Douglas coveted a rail head in Chicago for the new transcontinental railroad. This would make Chicago a major trade center for the country, not unlike New York City when the Erie Canal was completed. He knew increased economic power for his home state would translate as increased political power for him. The South, on the other hand, wanted the rail head located in

The use and importance of official crime statistics Research Paper Example

The use and importance of official crime statistics Research Paper Example The use and importance of official crime statistics Paper The use and importance of official crime statistics Paper This paper will consider which activities are officially counted as crime and feature in the official crime statistics, opening with a view as to why some activities do, whilst others, quite clearly and equally criminal, do not figure amongst these official statistics. This approach acknowledges that not all crimes, for whatever reasons, are reported to or acted upon by the police. We will consider serious and dangerous activities that some may deem equally criminal but which never find their way into the official statistics as a result of what Steven Box identifies as ideological mystification. Having examined this paradoxical situation, we will consider the futility of using crime statistics in the tracking of crimes, and in the implementation of measures against them. Before addressing this question, it would be helpful to be aware of what official criminal statistics represent in reality, and what they can actually tell us. Given this understanding, it seems that we can never be completely sure that the data, which represent certain activities as crime, fully reflects the true extent to which crime is being committed. There are many variables that need to be taken account of, such as the number of pursuits legally counted as crimes that are actually being reported to, and recorded by, the police. The most important issue here is the requirement for consistency in recording; yet the discretion that we know to be open to, and exercised by, the police affords them the freedom to manipulate the records in order to suit some hidden agenda or ulterior motive (e. g. he need for the police to meet Key Performance Indicators; or attempts to show crime as being higher or lower than the figures would in actual fact suggest), thus allowing the statistics to be constructed in such a way as to mislead and misinform politicians and the general public about the level of crime in our society. Therefore, if we do not have a clear picture from true and accurate statistics, it would appear to be futile to rely on these for the purposes of tracking crime or, indeed, in applying the measures taken against it. The dark figure of crime (unrecorded crimes) is not represented within the official criminal statistics. These unrecorded crimes can include anything from the pilfering of property in the workplace, to vandalism and the violent abuse of women and children within the home, (Muncie, J. 1998). These are crimes more usually picked up in self-reports or victimisation studies conducted by the British Crime Study (BCS) and which can be said to illustrate something of the disparity existent between the official statistics and peoples life experience of crimes. In 1982 and 1984, the BCS suggested that only about half of known crime is reported to the police. Since this is the case, and given the fact that very little is known about the bulk of criminal activity in Britain, the official crime statistics are far from representative of the reality of crime in Britain and so are of very little use in informing policy measures taken against it; although it could be argued that they may be of some use to certain politicians wishing to embark upon a law and order campaign. It could also be argued that these statistics may be used to point the finger at certain sections of the populace for purely political reasons. Steven Box (1981), poses the powerful argument, for example, that criminal laws are little more than ideological constructions representing the interests of an influential ruling elite. Box argues that laws tend to focus on those victimizing behaviours that are considered more serious and given greater prominence in the public perception, as constituting the most serious of social problems and deserving of no less serious responses. Crimes such as murder, rape, robbery and burglary are clearly reflected within the official crime statistics as perpetrated by predominantly young men of low socio-economic status. Amongst these, the uneducated, unemployed and ethnic minorities are over-represented and form the bulk of the prison population. This apparently tells us that particular sections of the populace are the most likely perpetrators of crime and criminal activity within society. However, statistics such as these do not tell us that, as Box indicates, far more serious crimes and criminality occur on a regular basis yet go unnoticed. A large number of these offences are crimes committed by the rich and powerful, which are carried out on the relatively powerless; real people who suffer avoidable death and serious injury for want of the proper implementation of current health and safety regulations at work and elsewhere. Criminal law also excludes from protection consumers who have been sold faulty products through the malpractices of manufacturers, or shareholders that incur losses resulting from the deliberate mismanagement of a company by its directors or senior management. (Box, 1981). Thus, the official criminal statistics would appear actually to hide the crimes of the more powerful, wealthy and privileged individuals within society whilst simultaneously serving to overemphasize and overstate those criminal activities of the weak. This effectively distorts and renders unreliable the official picture of crime as portrayed by the state. In relation to our question, it would appear then that the official crime statistics are far from representative of the true extent and reality of crime in our society, and although the vast majority of people wish to be protected from the very real crimes featured in the official statistics, they are notoriously unreliable indicators of the incidence of crime or, indeed, of the types of crime being committed in contemporary Britain. Therefore, the remainder of the question seems to be a fruitless pursuit unless we wish to advocate various conspiracy theories and speak in terms of the official crime statistics serving purposes such as controlling targeted sections of the populace by tracking their particular activities and informing the measures taken in combating these, whilst simultaneously serving to cover up the crimes of the rich and powerful elite and distract attention from their activities. In point of fact, that line of argument would result in the assertion that the official crime statistics actually serve to help maintain this particular, current, status quo.

A Study of the Conversion Options for the Bataan

T. S. undertook a study of the options for converting the Bataan Nuclear Power Station to fossil fuel (coal or natural gas) combustion. One aim of the study was to find another market for Philippine and Australian coal or natural gas (LNG). The essential question regarding the Bataan Reactor is: how to obtain a financial return from a very expensive power station that * has never produced electricity; * is costing the Philippinec State a sizeable sum in interest; and * has environmental, safety and social concerns over its use as a nuclear power station. The retrofitting of the turbine generator with a fossil fuel fired steam raising system was suggested as a means of utilising part of the plant, and obtaining some return for past and future expenditure. The report/proposal examined some options for fossil fuel firing, and compared those options with nuclear operation. Background The Bataan Nuclear Power Plant was completed in 1984, whilst construction commenced in 1976. It is a Westinghouse light water reactor, that uses pressurised water as it heat exchange medium between the reactor and the steam generators. Its design thermal capacity is 1876MW(t), whilst its rated power output is 621MW(e)1. The technology that is incorporated into the plant is essentially early seventies, but has been modified to incorporate more recent safety devices, such as those recommended by the US Nuclear Regulatory Commission, after evaluation of the Three Mile Island incident. The plant, which was in the process of commissioning at the time of the EDSA revolution, has not been fired, although nuclear fuel was delivered to it storage facilities. Maintenance has continued, with the integrity of the plant and ancillaries being ensured. Conclusion of Study The Philippine Government has previously stated that the Philippines will have nuclear power, but that power will come from new plant and not the Bataan reactor. President Ramos announced on the 8th October 1994 that the Reactor would be converted to a 1000MW combined cycle gas plant. (Although an announcement for a specific conversion scheme has been made, it is still considered that there is time for other options to be considered. ) We found that conversion is technically possible, but economically unwise. New and dedicated coal or natural gas fired power plants would give much higher efficiencies, and thus would give the Philippines much better value per peso spent on fuel consumed. The M. E. T. T. S. ‘s study concluded that the only way of obtaining a reasonable return from the Bataan ‘machine’ is to use it as a nuclear power plant. Our report specifically came to the following conclusions: * That the use of the present ‘nuclear’ turbine/generator in a fossil fired system would be highly wasteful of energy (fuel), A new pulverised coal power station and/or combined cycle natural gas power stations at other site(s), would be a better investment in terms of fuel efficiency and levellised power costs, * The Bataan site is inappropriate for coal fired plant, due to environmental constraints and materials (coal and ash) handling problems, * More assessable sites could be found for co mbined cycle natural gas fired plants around Manila Bay, and Batangas, * The Bataan reactor has been maintained in a good condition since mothballing, and The reactor is of basically sound design and construction, and could with modest expenditure become one of the most modern and safest light water reactors in East Asia. To fire the plant as a nuclear facility, the sea water intakes to the condensers would need to be cleaned (with some equipment being replaced), some of the reactor monitoring systems would need to be further upgraded, whilst the second power transmission system would need to be reconstructed. Staff would need to be retrained and re-licenced. A description of the study is presented in the attached article by Clarke, Ebeling and Cordero. The article was presenred at The First Philippine International Conference on Energy Efficiency and Demand Side Management, Manila, January 1995.

For comparison purposes figures are also presented for the refurbishm ent, commissioning and running the plant as a nuclear power station. Electricity costs from nuclear operation are considerably cheaper than for ither the two conversion options. If power costs was the only criteria for operating the plant then nuclear firing would clearly win. Both coal and natural gas conversions will have environmental consequences for the region. By the installation of best available technology and the application of best available practice, the impact will be minimised. The cost of technology and practice however will increase the cost of electricity produced by the plant. Table 1.

In each case (for the table) it has been assumed that the full capital cost has been borrowed. When financing packages are being considered, different pay-back periods are likely to be used. The periods are likely to increase with increasing debt. With the natural gas conversion option, an equity contribution would probably be included, since a BOT financing scheme may be used, that ties gas production, reticulation and use into one commercial package. The electricity costs for coal and natural gas conversion are based on a reasonably optimistic scenarios, where no excessive ancillary capital works are charged against the plant. If environmental or other factors require such works, then increase in the electricity cost would occur. It is further considered that the plant required for conversion would be sourced from low cost countries; China, India, Australia, the Philippines etc, as far as possible. The costings for conversion are further premised on the use of the site allocated for construction of PNPP 2, in that it is supplied at no cost, and is geologically stable. If the time required for the construction and commissioning is crucial, then the upgrading of the plant as a nuclear station is clearly the preferred choice. Further, the financial analyses indicate that the nuclear firing of the plant offers the cheapest electricity. Given that the nuclear fuel price is likely to remain stable over the foreseeable future (as against likely rises for coal and natural gas), the nuclear upgrading# and operation offers greater financial certainty to investors. # M. E. T. T. S. ‘s estimate for upgrading the nuclear plant to 1997/8 standards is $US380m. It is backed by further external assessment, and includes new safety features. $US300m is the cost of a basic upgrading based on calculations carried out by the National Power Corporation. SUMMARY – COAL FIRING The conversion of the PNPP I plant to coal firing has some advantages. Coal technology is well proven, and only a small variation in the normal use of that technology is required to convert the plant. The power station will have a capacity similar to the design capacity for the nuclear plant, and will not be the largest plant in the new echelon of Luzon’s power facilities. The plant of 800 MW(e) capacity will be relatively inexpensive at a capital cost of $US505m – without Flue Gas Desulphurisation, Selective Catalytic Reduction, or excessive expenditure on coal or ash handling and ignoring the previous expenditure on the nuclear system. A construction and commissioning period of 42 months is envisaged. The coal option however offers unique co-economic opportunities. The ash waste product would be valuable if used in ancillary industry. By using the Lahar produced by the Pinatubo eruption as an aggregate, with the ash, iron oxide and cement, valuable building materials could be produced. The disadvantages include designing and fitting an environmentally acceptable coal fired power station into the Bataan region. The materials handling alone will create many environmental, management and operational difficulties. The infrastructure requirements for materials handling will also raise engineering and environmental questions that will need to be solved before construction begins. Other environmental questions concerning emission reduction and control must also be answered before work can commence. Another major disadvantage is the requirement for premium fuel, that is expensive in 1994, and in all probability will become relatively more expensive as the demand for ‘clean’ coal increases in the future. SUMMARY – NATURAL GAS FIRING (COMBINED CYCLE, GAS TURBINE) Natural gas provides the cleanest option for the conversion of the Bataan power station to fossil fuel firing. It further offers the most flexible power output to the grid. Options exist for running a part (or whole) of the plant as a single cycle peak load provider, or running the whole plant as a base load facility. The environmental hazard that would be created by such a plant is low compared to coal. Thermal pollution to the sea would be greater than the nuclear option, in that if a 1700MW(e) plant was built with 46% efficiency, the waste heat would be 2000MW(t). This heat would be partially dissipated into the atmosphere (250MW) as against to the sea (1750MW). The additional heat discharge to the sea would be about 500MW(t). NOx emissions can be successfully controlled by modern technology. Steam or water injection, ammonia addition or innovative combustion designs will produce acceptable (but not zero) NOx emissions. At 1700MW(e), the power station would be the largest in the Philippines, and would certainly require a review of the Luzon energy plan. The total consumption of natural gas over a twenty five year period would be 2. 5 TCF; over half the entire Philippine projected resource from Palawan. Over a billion dollars in capital would be needed to build the plant, plus an additional substantial sum to supply the fuel; either as LNG or pipeline gas. The security of a large gas holding area would need to be addressed. Such a holding area and power station would make a relatively easy target when compared to a coal fired plant with coal yards or nuclear facilities. The installation of the gas turbines could be achieved in eighteen months, but the construction of the steam generators and carrying out modifications to the existing plant would take a further twenty four months. From the preliminary financial analysis, the construction of a new combined cycle power station makes better financial sense. A NUCLEAR COMPARISON Under the four headings (Technology, The Environment, Social and Political Concerns, and Economy) that were used to examine the coal-conversion option, a brief summary has been made of the nuclear option for comparison purposes. Technology Light water reactors are a very common type of nuclear reactor. They have good safety records, and most have high capacity factors. There development has been continuous, with technology now being available from Japan, Korea, France, the United Kingdom as well as the United States. They are used in close proximity to the Philippines (Japan, Korea and Taiwan) and have been armarked for use in Indonesia and Malaysia. The Bataan unit is 1970/80’s technology. It is however essentially the same as new units, and could be readily upgraded to 1990’s standards. The Environment The reactor will produce thermal pollution (waste heat) that will be disposed of, off Napot Point to the South China Sea. An environmental impact assessment cleared the plant for its designed heat disposal, and found that localised heating of the sea would not be excessive, given the strong currents that would ensure dispersion of the hot water. No other polluting emissions could be expected from the nuclear power plant. (Accidental emissions of radioactive material, are most unlikely. Once the plant was upgraded to 1997 standards, one accident in a million years could be expected. ) Social and Political Concerns The perceived problems at the Bataan power plant are its greatest liability. These problems include seismic instability, claims of faulty workmanship and the lack of experience of the operators. Many geological and seismic inspections have been carried out on the site, with the result being that no significant risk is apparent. To convince Philippine Society of the seismic safety of the plant, an educational programme would need to be carried out that emphasised the sites stability, and the high seismic safety factor of the plant (0. 4g). Part of the process of refurbishment and upgrading, would be quality assurance on all systems and components of the plant. Modern QA techniques would need to be used to provide the certainty that all significant parts of the plant meet the highest safety and operational standards. Initially foreign experts would be needed to run the plant. The retraining of Philippine staff would take considerable time and money, with the retrained staff spending a number of years assisting in operating similar plants in neighbouring countries. Economics By comparison with the costs of conversion to coal or natural gas, the refurbishment and upgrading of the plant for nuclear operation would be significantly cheaper. A maximum price of $US300m (including staff training) is a fair limit, compared to fossil fuel conversion alternatives. The nuclear option should have the shortest lag time in terms of upgrading and commissioning. If foreign staff were used to initially man the plant then a period of eighteen to twenty months would be needed for full operation. This relatively short period, may be valuable in that the some of the expensive, old or temporary oil fired power plant could be retired early. Fuel costs, plus operation and management costs for LWRs should cost no more than ? US 2/kWH (0. 54 Centavos/kWH). If the interest on the $US 300m was 12%, with a pay-back period of twenty years for the capital, then a further 0. 9? US/kWH would be added to the power cost. The total power cost would be 2. 9? US/kWH (0. 78 Centavos/kWH). If consideration was given to running the Bataan power station as a nuclear plant, then the environmental and economic benefits (as well as safety) should be emphasised, to overcome social and political opposition. THE PHILIPPINES AND THE NUCLEAR CYCLE The Philippines would be an importer of nuclear fuel and an exporter of spent fuel. The fuel that the reactor would use would be lightly enriched. As the uranium 235 is consumed, some plutonium is formed, part of which is also used up as fuel. The spent fuel rods contain a depleted amount of uranium 235, a little plutonium but mostly non-fissile uranium 238. These fuel rods can be reused in heavy water type reactors (CANDU) that are running in Japan, Korea and Taiwan, as primary fuel. All the wastes would be processed by those countries, whilst the Philippines would receive a financial return for its used nuclear fuel. This is a win-win situation. The sale of the used fuel rods could bring the net production cost of electricity (fuel plus operations and management) to under ? US 1. 5/kWH. PLANT SECURITY AND THE NUCLEAR OPTION Unfortunately there is an ongoing insurgency situation in the Philippines. The insurgency problems are no longer major, and in all probability will recede. All major plant however does need a security system. The Bataan plant was constructed with good external, perimeter and internal security systems. There are commonly perceived notions that Nuclear Plants are susceptible to terrorist attack. These notions are based on a lack of understanding of the compact nature of nuclear plants, and the presence of very considerable containment structures for the reactor and fuel stores – especially American designed LWRs. The plant is easy to guard, and would be able to resist attack with light weapons, including rocket propelled grenades etc. The damage from such an attack would be limited to the knocking out of ancillary plant and structures, including the transformer yard, the auxiliary fuel tanks and administration building. Notes 1. The above power cost figures are based on 1997 projected fuel prices, 12% interest, 85% availability, and 20 years amortisation.. The price of coal and natural gas are considered to be more liable for major increases, than nuclear fuel. The Asian demand for both coal and gas is expected to outstrip supply in the coming decade. 2. The estimated construction time includes planning and design, equipment construction, site modification, plant erection and commissioning, and staff training (coal and natural gas conversion). If major ancillary works are required (eg. major wharves, ash and coal pipelines, shipping channels etc), then both an increase in the construction time and costs could be expected. A Study of the Conversion Options for the Bataan T. S. undertook a study of the options for converting the Bataan Nuclear Power Station to fossil fuel (coal or natural gas) combustion. One aim of the study was to find another market for Philippine and Australian coal or natural gas (LNG).

SUMMARY – COAL FIRING The conversion of the PNPP I plant to coal firing has some advantages. Coal technology is well proven, and only a small variation in the normal use of that technology is required to convert the plant. The power station will have a capacity similar to the design capacity for the nuclear plant, and will not be the largest plant in the new echelon of Luzon’s power facilities. The plant of 800 MW(e) capacity will be relatively inexpensive at a capital cost of $US505m – without Flue Gas Desulphurisation, Selective Catalytic Reduction, or excessive expenditure on coal or ash handling and ignoring the previous expenditure on the nuclear system. A construction and commissioning period of 42 months is envisaged. The coal option however offers unique co-economic opportunities. The ash waste product would be valuable if used in ancillary industry. By using the Lahar produced by the Pinatubo eruption as an aggregate, with the ash, iron oxide and cement, valuable building materials could be produced. The disadvantages include designing and fitting an environmentally acceptable coal fired power station into the Bataan region. The materials handling alone will create many environmental, management and operational difficulties. The infrastructure requirements for materials handling will also raise engineering and environmental questions that will need to be solved before construction begins. Other environmental questions concerning emission reduction and control must also be answered before work can commence. Another major disadvantage is the requirement for premium fuel, that is expensive in 1994, and in all probability will become relatively more expensive as the demand for ‘clean’ coal increases in the future. SUMMARY – NATURAL GAS FIRING (COMBINED CYCLE, GAS TURBINE) Natural gas provides the cleanest option for the conversion of the Bataan power station to fossil fuel firing. It further offers the most flexible power output to the grid. Options exist for running a part (or whole) of the plant as a single cycle peak load provider, or running the whole plant as a base load facility. The environmental hazard that would be created by such a plant is low compared to coal. Thermal pollution to the sea would be greater than the nuclear option, in that if a 1700MW(e) plant was built with 46% efficiency, the waste heat would be 2000MW(t). This heat would be partially dissipated into the atmosphere (250MW) as against to the sea (1750MW). The additional heat discharge to the sea would be about 500MW(t). NOx emissions can be successfully controlled by modern technology. Steam or water injection, ammonia addition or innovative combustion designs will produce acceptable (but not zero) NOx emissions. At 1700MW(e), the power station would be the largest in the Philippines, and would certainly require a review of the Luzon energy plan. The total consumption of natural gas over a twenty five year period would be 2. 5 TCF; over half the entire Philippine projected resource from Palawan. Over a billion dollars in capital would be needed to build the plant, plus an additional substantial sum to supply the fuel; either as LNG or pipeline gas. The security of a large gas holding area would need to be addressed. Such a holding area and power station would make a relatively easy target when compared to a coal fired plant with coal yards or nuclear facilities. The installation of the gas turbines could be achieved in eighteen months, but the construction of the steam generators and carrying out modifications to the existing plant would take a further twenty four months. From the preliminary financial analysis, the construction of a new combined cycle power station makes better financial sense. A NUCLEAR COMPARISON Under the four headings (Technology, The Environment, Social and Political Concerns, and Economy) that were used to examine the coal-conversion option, a brief summary has been made of the nuclear option for comparison purposes. Technology Light water reactors are a very common type of nuclear reactor. They have good safety records, and most have high capacity factors. There development has been continuous, with technology now being available from Japan, Korea, France, the United Kingdom as well as the United States. They are used in close proximity to the Philippines (Japan, Korea and Taiwan) and have been armarked for use in Indonesia and Malaysia. The Bataan unit is 1970/80’s technology. It is however essentially the same as new units, and could be readily upgraded to 1990’s standards. The Environment The reactor will produce thermal pollution (waste heat) that will be disposed of, off Napot Point to the South China Sea. An environmental impact assessment cleared the plant for its designed heat disposal, and found that localised heating of the sea would not be excessive, given the strong currents that would ensure dispersion of the hot water. No other polluting emissions could be expected from the nuclear power plant. (Accidental emissions of radioactive material, are most unlikely. Once the plant was upgraded to 1997 standards, one accident in a million years could be expected. ) Social and Political Concerns The perceived problems at the Bataan power plant are its greatest liability. These problems include seismic instability, claims of faulty workmanship and the lack of experience of the operators. Many geological and seismic inspections have been carried out on the site, with the result being that no significant risk is apparent. To convince Philippine Society of the seismic safety of the plant, an educational programme would need to be carried out that emphasised the sites stability, and the high seismic safety factor of the plant (0. 4g). Part of the process of refurbishment and upgrading, would be quality assurance on all systems and components of the plant. Modern QA techniques would need to be used to provide the certainty that all significant parts of the plant meet the highest safety and operational standards. Initially foreign experts would be needed to run the plant. The retraining of Philippine staff would take considerable time and money, with the retrained staff spending a number of years assisting in operating similar plants in neighbouring countries. Economics By comparison with the costs of conversion to coal or natural gas, the refurbishment and upgrading of the plant for nuclear operation would be significantly cheaper. A maximum price of $US300m (including staff training) is a fair limit, compared to fossil fuel conversion alternatives. The nuclear option should have the shortest lag time in terms of upgrading and commissioning. If foreign staff were used to initially man the plant then a period of eighteen to twenty months would be needed for full operation. This relatively short period, may be valuable in that the some of the expensive, old or temporary oil fired power plant could be retired early. Fuel costs, plus operation and management costs for LWRs should cost no more than ? US 2/kWH (0. 54 Centavos/kWH). If the interest on the $US 300m was 12%, with a pay-back period of twenty years for the capital, then a further 0. 9? US/kWH would be added to the power cost. The total power cost would be 2. 9? US/kWH (0. 78 Centavos/kWH). If consideration was given to running the Bataan power station as a nuclear plant, then the environmental and economic benefits (as well as safety) should be emphasised, to overcome social and political opposition. THE PHILIPPINES AND THE NUCLEAR CYCLE The Philippines would be an importer of nuclear fuel and an exporter of spent fuel. The fuel that the reactor would use would be lightly enriched. As the uranium 235 is consumed, some plutonium is formed, part of which is also used up as fuel. The spent fuel rods contain a depleted amount of uranium 235, a little plutonium but mostly non-fissile uranium 238. These fuel rods can be reused in heavy water type reactors (CANDU) that are running in Japan, Korea and Taiwan, as primary fuel. All the wastes would be processed by those countries, whilst the Philippines would receive a financial return for its used nuclear fuel. This is a win-win situation. The sale of the used fuel rods could bring the net production cost of electricity (fuel plus operations and management) to under ? US 1. 5/kWH. PLANT SECURITY AND THE NUCLEAR OPTION Unfortunately there is an ongoing insurgency situation in the Philippines. The insurgency problems are no longer major, and in all probability will recede. All major plant however does need a security system. The Bataan plant was constructed with good external, perimeter and internal security systems. There are commonly perceived notions that Nuclear Plants are susceptible to terrorist attack. These notions are based on a lack of understanding of the compact nature of nuclear plants, and the presence of very considerable containment structures for the reactor and fuel stores – especially American designed LWRs. The plant is easy to guard, and would be able to resist attack with light weapons, including rocket propelled grenades etc. The damage from such an attack would be limited to the knocking out of ancillary plant and structures, including the transformer yard, the auxiliary fuel tanks and administration building. Notes 1. The above power cost figures are based on 1997 projected fuel prices, 12% interest, 85% availability, and 20 years amortisation.. The price of coal and natural gas are considered to be more liable for major increases, than nuclear fuel. The Asian demand for both coal and gas is expected to outstrip supply in the coming decade. 2. The estimated construction time includes planning and design, equipment construction, site modification, plant erection and commissioning, and staff training (coal and natural gas conversion). If major ancillary works are required (eg. major wharves, ash and coal pipelines, shipping channels etc), then both an increase in the construction time and costs could be expected.

Stem cell research and should it be federally funded Paper

Stem cell and should it be federally funded - Research Paper Example The present enthusiasm over prospective stem cell-produced remedies radiates from the new innovations of genetic biology. Though one cannot forecast the results from basic research, there is enough information available to suggest that a good deal of this enthusiasm is justified. This enthusiasm is not shared by those of the religious right. This faction is opposed to embryonic stem cell research which they claim as immoral and characterize as devaluing human life, much the same as does abortion, drawing a link between the two. This discussion will provide a brief overview of stem cell research and its benefits to society, the debate surrounding the issue and the arguments for continued research. Embryonic stem cells possess the ability to restore defective or damaged tissues which would heal or regenerate organs which have been adversely affected by a degenerative disease. Cell therapy has the very real potential to provide new cures for diabetes, cancer, kidney disease, macular deg eneration, multiple sclerosis and many other kinds of diseases. Cell therapy has also demonstrated a great potential to help repair and regenerate spinal cord injuries which would help paralyzed patients recapture lost body functions. The possibilities are limitless including greatly advancing the human lifespan because aging organs could be replenished. â€Å"We may even have the ability one day to grow our own organs for transplantation from our own stem cells, eliminating the danger of organ rejection.† 1 The three main objectives given for pursuing stem cell research are obtaining vital scientific information about embryonic development; curing incapacitating ailments and for testing new drugs instead of having to use animals. The scientific techniques for obtaining stem cells could lead to unparalleled advances and even cures for these and other ailments. It has been substantiated from animal research that stem cells can be differentiated into cells that will behave appr opriately in their transplanted location. For example, the transplantation of stem cells following treatments for cancer has found much success for many years. There are numerous potential sources. The first is bone marrow stem cells. This type of stem cell is probably the most recognized of the stem cells. It has been used routinely to treat a variety of blood and bone marrow diseases, blood cancers and immune disorders. Leukemia is the most recognized disease that has been treated with a bone marrow transplant. New evidence suggests that bone marrow stem cells may be able to differentiate (the process by which an unspecialized cell acquires the features of a specialized cell) into cells that make up tissues outside of the blood such as liver and muscle. 2 The second type of stem cell is the adult stem cell. An adult stem cell is thought to be an undifferentiated cell, found among differentiated cells in tissues or organs. These cells can renew themselves and can differentiate to b ecome some or all of the major specialized cells types in the tissue and muscle it resides in. The primary function of this type of stem cell is to maintain and repair the tissue in which they reside. Because there are a very limited number of adult stem cells in each tissue coupled with their limited capacity to divide; making generation of large quantities of these cells is

Kingship In Anglo saxon Britain Term Paper Example | Topics and Well Written Essays - 2500 words

Kingship In Anglo saxon Britain - Term Paper Example The kingdoms stood alone for several centuries during which there occurred Christianization of the citizens. Before the 10th century, these kingdoms were rivals as their respective leaders wanted to gain control over other kingdoms. However, it was the threats of possible Viking as well as Danish settlers’ invasion of the island of Britain that saw the unification of the seven kingdoms into one known as England under the hegemony of Wessex between the ninth and tenth centuries. With the unification and the formation of the new kingdom, an English medieval kingship that is still in use to date came into being. This kingship started with Alfred of Wessex and his succession line gave the English state substance2. The kingship acted as the institution, which had the maintenance of social order as its ultimate responsibility. A medieval king, one needed to adopt delicate approaches that aimed to pay attention closely to the sensibilities of the locals in order to attain success. As such, different rulers of England employed codes that have differences and similarities at the same time. These codes have gone a long way in defining the modes of leadership, the direction it takes, as well as the codes and laws o f the generations of administration that followed them. Alfred’s succession was unexpected with him having four older brothers, which meant that he was fifth in line of succession. However, with the deaths of all the older brothers, Alfred took the throne aged 21 at a time when the kingdom of Wessex was in conflict with the Danes and the Vikings as in all kingdoms in the British island at the time. However, his greatest battle was with the Danes with whom he delved into guerilla tactics and finally defeated them. He also resorted to dialogue when he realized that he could not remove the Danes from the island, with a few intermarriages occurring and even resulting in the conversion of the Danish king into

The American Dream in John Steinbecks East of Eden :: East of Eden Essays

The American Dream in East of Eden It is what every American strives for in life, but no one ever seems to achieve fully; it is the hopes and aspirations of every American, yet rarely are these goals ever met. It is the American Dream. In East of Eden, John Steinbeck displays different aspects of the American Dream through the desires and wishes of each character. Though each character in East of Eden may have a slightly different idea of what the American Dream is, becoming rich and wanting a better life for one's children seem to be a common thread in the lives of Faye and Cathy, Adam, and Cyrus. Becoming rich and financially stable is arguably the most important part of the American Dream. Every character seems to think it important, even those who do not have a lot of money. Faye obtains her wealth by running a successful whore house. When adopting Cathy as her daughter, Faye tells her, "I--no, we--have cash and securities in excess of sixty thousand dollars. In my desk are notations of accounts and safe-deposit boxes. I sold the place in Sacramento for a very good price" (233). Upon hearing this news, Cathy knows that her act of being daughterly has worked and she will inherit a lot of money. Being financially secure is important to both of them and they think it is the only way for them to enjoy the pleasures of life. Adam Trask is also a strong believer that money is the only way for one to live a life of luxury. When inheriting the money form his father, Cyrus, Adam is anxious to spend the money to build a better life for his brother and himself. While his brother is skeptical, Adam decides that he should move west in order to buy a nice farm to raise a family on. Upon his arrival at Salinas, Adam is willing to pay whatever it takes to buy the best plot of land. Only with money would this have been possible and would he be happy. Cyrus Trask believes that money makes a better life, too. If he did not think this, he would not have thought it important to leave his

Imagine you are Macbeth Essay

Q- Imagine you are Macbeth. Write a diary entry in which you express your thoughts and feelings at Act 1 Scene 7 and a later entry at some time later one, possible after meeting the doctor. Today Lady Macbeth has convinced me. We are going to ahead with the plot to kill the king. When she first told me about the plan I was very doubtful. I don’t think I will be able to live with myself with the guilt of killing the king. I know this is wrong. What about if we get caught? I am just weighing up the situation. Perhaps I don’t need to do anything to become king, â€Å"If chance will have me king, why, chance may crown me without stir†. I possess uncertainty of whether it is righteous to take the life of such a great king in order to feed my hunger for power. As I was thinking about this gesture, I left the chamber and decided not to do the deed. The idea of killing the king came from me first, this was when I heard the witches prophecies. When I first met the witches, they told me 3 predictions. They said, â€Å"All hail, Macbeth! Hail to thee, Thane of Glamis!† â€Å"All hail, Macbeth! Hail to thee, Thane of Cawdor!† â€Å"All hail, Macbeth! That shalt be king hereafter!† When I heard this I was shocked and couldn’t believe it. Banquo was with me and he asked them, â€Å"Which outward ye show? My noble partner you great with present grace, and great prediction of noble having and of royal hope that he slems rapt withal†. They then told us the final prediction, â€Å"Thou shalt get kings, though be none†. To us this meant that he will not be king but his children will. This was all so confusing. I know I am Thane of Glamis but how can I be the Thane of Cawdor? He still lives as a prosperous gentleman. Then there is me to become king. This is not within the prospect of my belief. Before we could say anything else they vanished. As Banquo and I were talking about the predictions, Ross came with some exciting news. He told me that as I fought well in the battle, I get the reward as the Thane of Cawdor. Mine and Banquo faces dropped with astonishment. â€Å"The Thane of Cawdor lives. Why do you dress me in borrowed robed?† I asked Ross. He then told us that he had died. At this point I had no idea of killing the king. I thought I would never be king and if I was to how would I? The witches offered me great enticement, but it is up to me to fail in the temptation or to be strong enough to resist their captivation. As I was thinking about this, Lady Macbeth came in. I knew this was the best time to tell her. I said, â€Å"We will proceed no further in this business†. She looked at me with great hate but I knew I said the right thing. â€Å"Was the hope drunk?† said Lady Macbeth, â€Å"Such I account thy love, art thou afeard to be the same in thin own act and valour, as thou art in desire?†. She was saying to me that I was drunk and I didn’t know what I was saying. She said that my love is worth nothing if I refuse to go through with the plan, and my love is as accountable as my in decisiveness. She also questions my masculinity and criticises my desire to be king. She used emotional blackmail to seduce me to proceed with this ambitious enterprise, â€Å"When you durst do it, then you were a man†. She makes an analogy to emphasise the importance of keeping my promise. After listening to her I felt very offended. I knew I had to do this or I will regret it all my life. I wanted to prove 3 things that I am a man, my love for my wife, and my desire to be king. To prove these I need to murder king Duncan, so I am. Today the doctor has come and said my wife is ill but he has no cure. This is very disturbing because I noticed she was acting a bit strange after we did that deed. After we murdered king Duncan she was very confident, unlike me. She even toke the daggers back into Duncan’s chamber for me and also she helps me wash the blood off my hands. She helped me pull me together psychologically. When I saw the ghost of Banquo, it caused me stress and concern. This put huge pressure on Lady Macbeth. Even though she cannot see the apparition herself she had to cover up for me. This put a lot of emotional pressure on her. She then tried to get me out of this strange state of mind by once again questioning my manhood, while at the same time giving the guests the excuse that I am not well. She takes control and tells all the guests to leave. I think she has kept her anger and fear in and since I have done more murders she feels more guilty and I have noticed she talks to herself. Since then her behaviour has changed and it shows carefully that her contrived mask slipped. In her sleepwalking she reveals the guilt and anxieties by which she is tortured. But her loyalty to me remains intact. She came to me once and said, â€Å"No more O’that, you mar all with this starting†, this was confusing. She has given all and now her present is overwhelming by the past, like what she said, â€Å"What’s done cannot be undone†. She is saying that we can’t change the past. But it was her who thought of the idea and it was her who convinced me. She is totally regretting it now. The doctor even couldn’t believe it, â€Å"I have two nights watched with you, but can perceive no truth in your report†. I don’t know what to do. I will just give some time to her and will see what will happen.
