How Socio-Economic Classes Contributed to Events in 1800 Europe Essay Example for Free

How Socio-Economic Classes Contributed to Events in 1800 Europe EssayDescribed as the divine distribution of men into unlike ranks, and at the same date uniting them into one society (Gladstone, 1896), the socio-economic course order formed the structure and foundation of society in Europe. Consisting of three obvious entities and with a strong correspondence between economic prosperity and cordial standing, it would also serve as the backdrop for which historical phenomena would occur.Europes favorable order was not just the environment in which these events would materialize, but also a fundamental causal factor in three notable events The french Revolution (1789-1799), The French Revolution of 1848 and Britains Industrial Revolution (1750 onwards). However, the origins of these events were also contingent upon other circumstantial factors. The roots of the first French change, arguably, argon in The wisdom the period of the philosophers.New philosophies advocating hum an rationality came to form by the mid 1700s and were propelled into popular thought after the isolated, and highly charged, Jean Callas calamity . Philosophers like Voltaire found the perfect vehicle in this incident to question the arbitrary use of power so prevalent in French society. The monarchy and the battlefront of the Social Order soon came into question. Across Europe, cafes sprung out to host discussion centered on the common theme of reason. Society cleaved toward enlightened ideas of rationality, equality and liberalism, leaders to the growing questioning of the existing monarchial power structure.Alternative political ideologies for the state, from personalities like Rousseau and Locke, sprouted and undermined the legitimacy of the monarchy. While The Enlightenment is responsible for creating pressure from society against the monarchy, these ideas would consider been impotent without suitable ground. The socio-economic categorizing of European society is a more fun damental cause of the first French Revolution because it provided this ground. The rigidity of the cordial order in late 17th century France accounts for the origins of the first French revolution.In theory, the loving divisions were permeable and promoted mobility (Roberts, 1997). Across Europe, titles and estates could be purchased and so also, the privilege of the splendor. However the reality was oftentimes different. In light of booming trade, the demand for titles from the French bourgeoisie and returning nobility outstripped the number permitted by the social order . Furthermore, while the bourgeoisie enjoyed change magnitude economic power and could live equally, if not exceedingly, extravagant lives as the nobility, the social order shut this community out from the benefits of social privilege .This was exacerbated by the nobilitys stress on privilege in response to the new Bourgeois economic threat. The systems disregard of merit in indue of hereditary, and the funda mentally irrational social construct sowed discontentment within the second and third estate, where the ideals of enlightenment rationality and equality, would find willing subscribers. Riding on the resentment toward societys order and fuelled by The Enlightenments ideas did the French Revolution tear its way through to the Bastille.While the first French revolution was understandably a social battle, one could argue that the revolution of 1848 was born out of opposition to economic factors than on societys social construct. The time leading up to 1848 was a time of gradual industrialization for France. Its products rapid urbanization and changes in economic practices, broke familiar social patterns of the workings class. For instance, the commercial-grade system was rewritten by doing away with the cottage industry and previously public drops, privatized.Added to this, a burgeoning population, severe industrial and agricultural depressions in 1846 and Louis-Phillipes inaction in alleviating rural and urban poverty culminated to create great peasant discontent. The economic change that accompanied its deterioration galvanized the working class, triggering the third French revolution in 1848 aptly, also known as a Workers Revolution. However, it is artificial to separate economics from social class since there is a correspondence between social hierarchy and wealth. They ar, after all, aptly named socio-economic classes.In analyzing yet another French revolution, an important observation to make is the persistence of Europes social order. Though the 1830 revolution delivered another great blow to the old social order (Magraw, 1987), and promised equality in opportunity and economic liberalism manifest in the abolishment of seigneurial practices for all, much had remained the same. Succinctly captured by Cobbans argument that it did not matter whether we called it aristocracy or bourgeoisie , the cleaving of the aristocracy and bourgeoisie shows an adapti on, not an eradication of the social order.The aristocracy kept to their ranks by continuing their distinctive politics and marriage practices (Magraw, 1987). Since most engaged with capitalism, they were mostly able to maintain their privileged lifestyle and figure of much of the land . The Bourgeoisie continued to thrive, especially under the Bourgeois King and even went as far as to convert their wealth into land ownership. This neo-feudalism masquerading as the product of laissez faire economic practices, and the continuation of aristocratic dominance came at the expense of the working class. Thus did the working class continue in their economically disadvantaged positions.Their economic dependence on the old orders aristocracy, had merely been replaced with a dependence on remnants of the same old order and a new Bourgeois one. The social order is a more fundamental account for the workers revolution, since it was responsible for creating the economic grievances of the working class which became the fuel for the 1848 revolution. The European social order again features as a causal factor in Britains Industrial Revolution. It is the very hierarchical nature of the class system that functioned as the engine for the Industrial Revolution.The industrial entrepreneurs of Britain, the main thrust for the innovation that characterized the revolution, took hold of Britains mineral resource advantage to affect rapid development. The motivations behind entrepreneurship are postdated back to the make-up of society. Since social privilege was linked with economic wealth, successful merchants strived to purchase titles and convert their wealth into social status (Briggs, 1979). In this way, the extravagance of direful life, held in high regard, could be emulated. However, it is admittedly reductionistic to exclusively use the quest for noblehood to account for an entire revolution.Coupled with the desire for social advancement were also ideas from The Enlightenment and The Scientific Revolution laissez faire economic practices and technological advancement respectively. Society as a whole was geared toward revolutionary development, equipped with the required ideology and possessing the necessary scientific capability. Nonetheless, the power of science and the power of thought would have remained a means without an end if not for the existence of Europes social class as the motivation to individuals for conomic advancement. Furthermore, the narrow elite which feature in Europes social order meant that there was a prolific number from the working class available for cheap employment and indeed, were the working class called upon for this. By 1850, more than 50% of the population were living in towns and city to work in factories and city-bound industries. The abundance of cheap labor comes from the old social orders narrow top and wide base, and it sustained and accelerated industrialization to revolutionary measures.Thus, we trace back the o rigins of the Industrial revolution to socio-economic classes. Social hierarchical ascension was the motivation, and the demographic make-up, the sustenance. Evidently, the causality of the three historical events covered is not monolithic. Though the contributing factors are layered and many, the role of socio-economic class is central. Its rigid, persistent and hierarchical institution shaped the motivations of humanity and in doing so, account for the origins of major events in History.

Effect of Interventions on Mental Health of Offshore Workers

Effect of Interventions on Mental Health of Offshore Workers5.3 Study 2 Qualitative InsightsResearch Question what is the deed of Intervention policies, from the posture of the offshore industry, on the affable health of offshore workers?Based on the views of the offshore representatives who participated in this lease, this research identified five themes which aim to explain the effect of intervention policies on the mental health of offshore workers.5.3.1 Theme One Mental Health Aw benessUpon reflection of the quotes associated with theme one, it can be seen that P1 is satisfactory to expand on how mental health problems can arise, non only from personal experiences save from the workplace itself. According to Mind (2011), employer awareness of mental health at work in the UK is poor, with most senior representatives vastly underestimating the scale of the problem and how it can affect companies worldwide. Awareness of mental health conditions amongst circumspection and t heir employees, done education, training and communication can reduce negative attitudes and stigma attached to the adjustments being put in place (Department of Health 2012).Educating people on mental health conditions is seen to be an stiff method to fight stigma. A field of operations conducted by Pinfold et al (2005) used mental health awareness programmes in schools in UK and Canada to combat stigmatism and to educate young people on misinformation surrounding mental health conditions. The study provided evidence to suggest that short educational workshops can let on positive flip in young peoples views of mental illness. Whilst, this cannot be applied directly to the Oil and Gas industry, it spiritedlights the benefits of awareness raising sessions.However, on the contrary OECD (2012) suggests that increased perceptions of mental health problems i.e. increasing rates of disability benefit, has changed the view of the work capacity of people with mental disorders. This im plies that better awareness has light-emitting diode to further exclusion from the workforce. These findings are similar to those discussed in the literature review whereby Stuart (2006) suggests prejudicial attitudes from employers expect a barrier for those suffering from mental health.5.3.2 Theme twain Macho CultureOrganisational agriculture has been defined as the specific collection of values and norms that are shared by people and groups in an organization and that go through the way they interact with each other and with stakeholders outside the organization (Hill and Jones 2001 p?).According to Wright (1994) (cited in Lindoe et al 2014 p. 65) the oil industry in western beau monde has always been dominated by a macho culture, meaning that macho type values, beliefs have governed the way in which offshore workers think and behave. This supports the secondary findings, as Ely Meyerson (2008) identified Macho culture to be significant barrier when getting males to admit t o their mistakes which may have caused or had the potential to cause an accident. However, the present study highlights that this macho culture and masculinity ideals from an organisational perspective are a significant barrier to their psychological help try oning.Deal and Kennedy (1982) identified four distinct culture types, determined by a combination of two parameters feedback (praise, rewards) and lay on the line (uncertainty). One of the cultures identified is the Tough Guy Macho Culture. They believe that this culture involves an organisation of risk takers that receive quick feedback on whether their actions were right or wrong.Culture is learned and reinforced (refer to learning theory) the Oil and Gas industry has existed for decades, for this culture to remain overabundant in contemporary society speaks volumes. It is important for the industry to ignite a cultural change, because this macho culture no longer fits the ever changing environment. e. e. cummings Worley (2005) have conducted research which suggests the following guidelines are effective for introducing cultural change. This first is to formulate a clear strategic vision, display Top-management commitment, model culture change at the highest level, modify the organisation to support organisational change, select and socialize newcomers and terminate deviants and finally to develop ethical and legal sensitivity.5.3.3 Theme Three Environmental DownfallsThe participants accept that mental health problems amongst offshore personnel can be linked to the environment, which as discussed in the literature review is isolating and environmentally challenging (Gardner 2003). some(prenominal) sources of stress and anxiety identified in relation to the isolated location of several North Sea Installations are sleeping patterns, shared living, lack of privacy, fiscal insecurity etc. However, Cooper and Sutherland (1987) stated that the key contributor to lower mental well- being was the stress a ssociated with being away from ones mate or partner, a factor which was identified at bottom the transcript.http//www.hse.gov.uk/research/othpdf/500-599/oth523.pdf5.3.4 Theme Four Reliance ReluctanceIt is clear from the findings in Chapter 4, that both participants are in agreement that in order for interventions and support mechanisms to be put in place the employee needs to endanger their mental health condition.However, it was highlighted by Stuart (2006) that prejudicial attitudes from employers remain a barrier for those suffering from mental health, hence the condition why employees are reluctant to disclose their psychiatric history.According to Haslam et als (2005) study, the reason for employee reluctance is because they feel they may be judged by their employer because the stigma attached to mental illness. Moreover,lack of promotional to show they are encouraging people to seek help?This was supported in the qualitative researcher findings by P1?However, there appear s to be a dissension between P1 and P2 in regards to their organisational reluctance to promote the lively interventions methods to the workforce.5.3.5 Theme Five Promotional ShortcomingsThe results of the present study suggests that the aim of health promotion in the Oil and Gas industry should be focused on (1) communicate the intervention methods that currently exist i.e. EAP (2) promote cultural change and encourage a culture whereby offshore workers did not feel ashamed to disclose their mental health condition (3) change the beliefs employees have roughly their employers regards for their well-being.Communicating mental health intervention methods shows the workforce that as an organisation they are not afraid to broach the subject, this in turn will encourage employees to come forward and seek the help available to them. Eisenberger et al (1986) stated that employees develop beliefs about the extent to which their organisation cares about their well-being. These beliefs hel p create an employees assessment of whether their employer will reward greater effort and help them to complete their jobs and cope with stressful situations. winning a social exchange perspective, such beliefs will be reciprocated through employee behaviours and deference. Evidence suggests that beliefs about an organisations concern for employee well-being have a positive impact on an individuals workforce performance, which, in turn, influences organizational performance (Podsakoff et al., 2000).5.4 LimitationsThere were a number of notable methodological limitations in this research and it is important that these are highlighted before going on to make any conclusions or early recommendations. Firstly, the lack of time and money accessible for the study hindered the amount of research that could be carried out. For example, the researcher would have liked to have used other participants such as OIMs or Counsellors to collect much detailed data.Furthermore, another possible imp rovement that could have been implemented is that rather than giving a questionnaire to participants, personal interviews would have elicited greater information regarding their noesis and attitudes towards mental health and their organisations current intervention methods. However, the researcher would not have been able to capture as many responses if this qualitative method was used.Chapter 6 cobblers last and Recommendations6.1 Recommendations6.1.1 Recommendations for the Oil and Gas IndustryFrom the study it is clear that stigma continues to influence the ways in which offshore personnel deal with their mental health condition. The results need that levels of depression, anxiety and stress are experienced amongst offshore workers, with high levels of stress being associated with the negative opinions of the current intervention methods in place. Therefore, to maximise support and to plug the duty of care is being directly adhered to, Oil and Gas companies worldwide should promote and educate offshore workers, onshore staff, and management about mental well-being.To do this, Management or those in a supervisory role should be provided with an opportunity to attend a two day Mental Health breeding courses which are available across the UK, some of which are free and some cost up to 100. This course covers a range of areas surrounding mental health, but most importantly it helps teach individuals to spot the signs and how to approach and intervene if necessary.Furthermore, prevention and early interventions should be the key focus when improving mental health within the workplace. There are three different types of prevention including Primary prevention (prevent the onset of the disorder), Secondary prevention (Detect early signs and intervene early) and finally, Tertiary prevention (Early effective treatment to prevent disability) (Martel 2009).Martel (2009) suggests that the above prevention strategies are essential when preventing work-related ment al health problems. However, in order to undertake any preventative program, it is essential that management are committed to change factors within their control and to implement action plans continuously.6.1.2 Future Research RecommendationsThe data set obtained in the present study provides opportunities for future research, which could throw further light on how mental health is experienced in the offshore environment and how the oil and gas industry as a whole reacts to these psychological mishaps. Combining the present data with medical history records of offshore personnel and formally reported mental health conditions to employers would be invaluable to see whether or not appropriate actions were taken.Furthermore, the present study did not attempt to identify the specific aspects of the offshore environment which may account for high levels of depression, anxiety and stress. If future research was to be conducted it may beneficial to investigate the key causes of psychologi cal distress in an offshore working environment, so that employers are able to tackle the issues at the forefront with appropriate interventions.

Advantage And Disadvantage Of Fixed Budget Accounting Essay

Advantage And Dis profit Of laid Budget Accounting EssayHowever from a birds- eye view, reckon can be defined as a management tools that put the managers in curtail of a finical health of the organisation. The objective of the budget is to measure of the financial complex body part of the organisation and budget is a tool that forces management to be accountable in a structured and objective way. How manager manage the budget is tell apart to their value. Budget facilities the planning and resources allocation and help to estimate, itemised, analysis and examined the entire product and military service that organisation offers to customer. (Seer, 2000, p.187).Budgeting is a simple process of consolidating budget and adhere them as closely as possible (Maitland,2000). It is a process turns manager attitudes forward looking to the future and planning managers are able to anticipate and react therefore to the potential problem onward it arises. Budgeting process allows manager to focus on the opportunities instead of figuratively. The budget system provides sustainability to worry process within an organisation. It is an utmost strategic process to the management. In other word by some researchers few business plan to fail but many a(prenominal) of those that collapsed failed to plan (Horngren, C. et al., 2000)The aim of budgeting is to trust management an idea how well the organisation is projecting the income goals and how well the organisation managing the working capital. The budgeting exercise should able to increase the profit, reduce inappropriate expenses and it also helps to set forth the markets (Thomsett, 1988, p.5). To achieve the budgeting aim, the management needs to build a budgeting system (Viscione , J. 1984).A budget system varies from organisation to organisation and it is not unitary concept. The fundamental concept of budget system involves estimating future performance of the organisation, comparing the true performance to the b udget and analysis the deviation of actual result against the budget. The divisors that determining the type or style of an organisation depend on the type of organisation, the leadership style, the method of preparation and desired result (Cherrington Cherrington, 1973, p.226)In general budgeting can be categories into ii primary categories (Cohen, J. et al., 1994) which are in operation(p) budget and financial budgetOperational budget covers revenues and expenses which involve day to day core business of the organisation which is radiation pattern operation activities. The main elements of the organisation operational budget include sales, production, inventory, materials, labours, overheads and R and D budgets.Financial budget controls the organisation financial aspect of the business. These budgets disclose the influences of the operational budget on the organisation, financial position and potential revenues. Financial budget include cash budget, capital expenditures budge t, balance sheet and income statement.There are many available methods of budgeting are available and it is main(prenominal) for the management to decide the correct methods that suits the organisation. Generally, management choices on how to start preparing budget fall into one of three study approaches (Rasmussen, Eichorn, 2000, p.19) which are Top-Down, Bottom- up and Top-down/bottom up. Please refer to figure 1 for Top-down and Bottom-up approaches.Figure 1 Top-down versus Bottom-up approaches cite Rasmussen, Eichorn, 2000, p.20-25Main BodyPart A (i)Budget approaches obligeed by United ConsultancyUnited Consultancy had presently adapted the approach of static budget trance preparing the budgeting. Static Budget is also known as immovable budget. Accordingly to Chartered Institute of Management Accountants of England, a fixed budget is a budget outline to hang on unchanged irrespective of take of actual activities attained. A static budget will reflect the expected result o r revenues of a budgeting year (Hansen and Mowen, 2011) of a responsibility centre for one level of activities. Normally fixed budget will be prepared in advance in advance the financial year as the court classified as fixed and it will not very in direct proportion of the level of activities. restore budget approaches are widely adapted by service industry (Reeve and Warren, 2007) and partly by some administrative functions of manufacturing companies such as purchasing, engineering and accounting. Fixed budget is used as an setive tool of personify. If, the level of activities attained are varies from the budgeted activities then fixed budget become ineffective. Comparatively, fixed budget is completely suitable for fixed expenses. A fixed budget is appropriate under static condition.Advantage and disadvantage of Fixed BudgetSmall business and service industries needs an overall budget to survive Fixed budget is most widely used by service and small industries as it help to cover on control the spending. At the same time fixed budget can cause more problems rather than giving a solution. A fixed budget will capitalised the calculation fixed expenses and help to forecast the bills to be paid by the business. For the variable expenses, fixed budget provides maximise spending limits and it helps to control the finances.The advantage of fixed budget is to help the business to prioritise the expenses. Fixed budget clearly distinction between the businesses needs and wants by forcing the business to remain consistent, it will also ensure that the bills are paid on time.The disadvantage of fixed budget as its operates to one level of natural process- the planned activity and it does not account for the business unpredictable activity. The actual always will be captured by a level of activity which is significantly difference from the planned activity. For example, to canvass the actual production cost increased at production levels of 1000 units against a st andard based on planned activity of 500 units could be misleading. Management will mislead thinking into that the production cost are out of control. An increase in production cost is avoidable as sight increases and it does not means that there is problem on increase cost occurred.Hiring adviser for Future budgeting for United ConsultancyA consultant is who has a position to guide a certain level of influences over an individual, a group or an organisation but who has no absolute power to make or to adapt changes into the organisation. It is the employee of the organisation has the power to decide whether to accept and implement the changes into the organisation. The consultant brings specialised skills, knowledge, expertises or accessing certain information into the organisation.Scott Hascall (2002) had analysed the advantage and disadvantages of consultants and United Consultancy need to consider before hiring consultants for involving in preparation of future budgets.Advanta ge of consultantsThe consultants are import and hired to fill competency gap in the organisation. According to Drucker (1979) suggested management consultant is an terrific and indeed a unique phenomenon as consultancy has the management skills, techniques, knowledge are best learned through exposures to and experiences with many industries as the typical executives lack of this frame of exposure. As Drucker notes, The executive works with same organisation or most with very few. Executives lack exposure and cannot gain it nor can be stimulate it. Consultant will able to transform the organisation and gain the exposure at the same time will add significant value by minify the problem resolution cycle time (Hagedorn, 1982). United Consultancy will be hiring consultant for preparation for future budget as it will bring pertly Idea, proficiency and impartiality objective (Gattiker and Larwood, 1985).Ifinedo (2011) had surveyed the impacting factor of consultants such as management, support, business, vision and external expertise. The result was found that all these factors influences the business system but the effect of external quality expertise was more important compared to the other factorsDisadvantage of consultantsAn organisation hiring a consultant to bring as it will bring the necessitate expertise, knowledge and experience to the organisation. Accordingly to Kelly (1979) hiring external consultant will be expensive as the payment will be based on their specialised skill in the respective field compare to internal consultant. An external consultant will not available at the right time and not easily accessible to the organisation as the internal executives. At the same time, and they are lack knowledge of organisation culture and working environment. Nonetheless consultants hold up the great level influences the senior management.A research by Norbck and kerblomMaster (2003) had highlighted that engagement of uncommitted management and inexperienc ed executives would lead to give an opportunity to consultants to take advantage of the situation and act to their make and attaining their own goals. There the experiences and capabilities of management consultants are critical for successful on management of consultants.One of most important factor to take into account when hiring consultants was mentioned by Luo and Liberatore (2009) which examined consultants objective and goals. The organisation main objective is to improve the performances while the consultants other goals such as knowledge acquisition and business growth. To overcome the situation, the organisation must well coordinate with consultants to achieve the desired goals.Part A (ii)United consultancy utilise Activity- based costing (ABC) for the allocation cost based fixed and varioable expenses. An effective planning of fixed and variable cost as followsPlanning to determine the variable overhead activates that add value for customers using the product and servic eEffectively planning to use the cost drivers in different level of activities.At the start of the fiscal year, a substantial share of fixed overhead are predetermined compare to variable. When the United Consultancy budget the fixed overhead cost, they should select the appropriate level of activity that will benefit the United Consultancy over long terms. This is a strategic decision.The key differences are how fixed costs are fixed to level activity and variable costs are allocated to level of activity.Actual CostingStandard CostingFixed CostActual PricesActual inputs are usedStandard PricesStandard inputs allowed for actual outputVariable CostActual indirect rateActual inputs usedStandard variable cost allocation rate.Standard quality of cost allocation base allowed for actual output.Activity- based costing has involves the following stageIdentify the level of activity that resources and cost to be associate.Identify the cost drivers associate level of activity. A cost driver is any factor that cause on drivers and activity cost.Calculate a cost rate per cost driver. separately activity should multiple cost driversAssign cost to products by multiplying the cost driver rate by volume of cost driver units consumed by the products.Indentify level of activity that resource is most engaging and challenging which based on activity based costing. A cost advantage rules that companies identify most important activity.Non Value added activities will be identified and these can be eliminated to improve the efficiency and profitability.Majority of the cost drivers are related either to the level of activity or the complexity of the production or marketing process.

Green Energy Means Renewable Energy Environmental Sciences Essay

unripened zip Means Renewable Energy Environmental Sciences Essay verdure nada means renewable dexterity that is vast alternative for the manipulation of fogy force outs such as petroleum. Other formulaic method utilize to can electric caral animation is such as geothermal, biomass, ocean, solar, farting, hydro, warmth content raise cells and etc. Biomass slide fastener is derived from the wastes and animal dung either by burning it or just go forth the wastes to lay off by itself to get bio kindle or biogas. Ocean vigor is gained from the ocean and there ar two types of them such as thermal get-up-and-go and mechanical zip. Hydrogen must go through reformation surgical operation or electrolysis process to be able to use for the fuel cells to provide electricity. The heading of the project is to choose seven types of renewable energies and explain its applications and advantages in detail.1. IntroductionGreen energy is sustainable energy, which means meeting the needs of the present with prohibited conciliative the future2. These alternative energy ascendants are said to be not harmful to humans and purlieu and also arenon polluting energy bloods. It basically reduces pollution and the impact on the environment that the existing energy source is ca utilize now and in the past by conventional energy sources such as fossil fuel, coal and wood. These are non renewable energy sources, also known as the brown energy1. These sources are main(prenominal)ly used in the harvest-timeion of electricity, heating and fuel for boilers. They pose excessive amount of pollutants, such as carbon monoxide and normality oxides, together with particles that could harm humans. These pollutants are the main contributors to the greenhouse gases that cause global warning. Brown energy are also types of sources that are typically reducing on our earth, which means it could not be re- pay backd to be used in future. The main aim for this athletic field on green energy is to literate the reader on what is green energy and the importance of these energy to substitute our current conventional energy resources. These plow is also to identify the main types of green energies available for the current technology practised in our world today with the history of energy development that brought to the reading of green energy.2. Green EnergySources of green energy come from the nature itself, creation free to be harvested. They are mainly derived from the sun (solar billet), cheat and piss supply. countermand turbines befuddle been used since old times to grind grains, where the term aerogenerator is derived from. A more expensive source would come from nuclear and bioenergy (biofuel and biogas).Nuclear former is also categorized in green energy as it does not produce greenhouse gases. Waste from nuclear power whole workss are problematic and self-destructive to be handled as it takes hundreds to thousands of years to decay be fore reaching the level that is not harmful to humans, workingss and the animals. But in order to completely wipe out the impost of fossil fuels to produce electricity, the number of nuclear plants has to be increased so that greenhouse gases emissions can be cut down massively.3 Energy from sun, wind and piddle are continuous but inconsistent. Rainy days that could affect solar power production and droughts that would affect body of water levels in dams are the main drawbacks of these energy sources.As renewable energy is sometimes inconsistent, excellent storage capacity is needed to store energy that are produced. It is unremarkably windier in the shadow time, but the demand would be lesser. Nuclear plants generate so much power at a particular time that they cannot be used at once. So mountainous battery banks are required in order to mesh with the electricity system and provide a consistent power supply.2.1 story of Energy DevelopmentThe history of energy consumption of human being dates back to 3000 BC where the Mesopotamians used petroleum to caulk ships and to build roads. Coals were used during the dye Age to heat up iron and shape them, as tumefy as in the Roman culture. This long history of non-renewable energy usage has urged the increase of green energy to re push through them in order to keep the future generation safe.42000 B.C.Crude oil was used to light lamps and heat up homes by the Chinese.200 B.C.Salt produced from brine using natural gas from underground by Chinese.600 B.C.Static Electricity found by Thales of Miletus by rubbing amber.250 four hundred A.D.First water-powered Mills make by the Romans600 A.D.Greek Fire was invented by the Persians and Arabs, a form of burning liquid used greatly in the tough Empire as weapon.500 900 A.DWindmills were built to pump water and grind grains by the Persians.Late 1500sCoal was imported greatly by US, up to 108,000 tons until the 1800s.1700sA kite that transmitted electricity throug h its wet cord was found by Ben Franklin. A breakthrough in electricity discovery.1800-1826US had the depression electric utility.Mid 1800s-1950Wood as the primary source of fuel, but decreased after the shift back to coal.1870-1880Gas and alcohol using beginning(a) combustion engine. First U.S. power plant to produce electricity opened (Thomas Edisons Pearl Street Station)1888First wind turbine generating electricity in Cleveland, Ohio.Early 1900sgeothermal used to produce electricity commercially by the Italians1938Nuclear Fission discovered by the Germans.1940-1950The Atomic Energy Act implementation and the first electricity were produced by using nuclear power.1950sFirst silicon solar cell was invented (solar photovoltaic).1960sNational Environmental Policy Act and Clean denude Act in US implementation to protect the environment and reduce pollution.1970sDepartment of Energy (DOE) were formed. pissing from power plant was controlled with Clean Water Act in 1972.1974Developm ent of renewable energy was initiated and supported by the National Renewable Energy Laboratory.1980sFirst wind farm built in the United States.2.2 Giga watts of power produced in California.1990sNatural gas was used in almost 50percent of homes in US for heating.Towards the Greener SolutionTill 2007, 24 states adopted policies for increasing the production of renewable energy.2.2 Importance of Green EnergyResearch from scientific evidence are showing that what this present generation is doing go out impact the environment in the next 50 100 years. The fact that only one earth is known by human being urges organisation and private sectors to find solutions to reduce pollution and having a lifestyle that is more eco-friendly. A few reasons on why green energy is important.Non renewable fossil fuels burning are causing greenhouse gases that cause global warming. Carbon dioxide, methane and nitrogen oxides are released into the atmosphere, dissolving into raindrops and causing acid rains. Acid rains damages crops, plants and forests. aquatic organisms are also affected by this as lakes and rivers pH levels are altered. Human built structures such as steel bridges, marble statues and limestone buildings are being eroded by acid rain.10Figure 3 is a pie chart showing the anthropogenic greenhouse gas emissions in the U.S. by gas type. fogey fuels such as oil and coal are also supply that is not endless. Sooner or later the supply will vanish and unprocurable for future generations.Wind, water and solar energy are constant, sustainable and 100 percent clean energy. It does not cause negative impact on environment such as pollutant and waste. This energy type is free as well.Humans would benefits in health as reduced pollutants would provide cleaner and more breathable behavior. Lands would be saved as waste management is not necessary. Cleaner water for domestic usage and aquatic organism a would be available.Jobs opportunity would arise in rural areas as most r enewable energy plants are located far from cities. Regional development also would benefit from this.893. Types of Green Energy3.1 BiomassBiomass is derived from farm wastes, animal wastes, plant oils, crops and some kind of garbage 11. Energy that is generated from the wastes is called bio power or bioenergy 11. Biomass can be processed further to obtain biofuels or burned directly to obtain bioenergy11. The energy obtained from burning the wastes can be converted into heat, electricity and mechanical energy 1.3.1.1 Types of biofuelsSolid form its obtained from the burning of constitutional material such as animal wastes, wood, grain and other types of garbages 11.Liquid form- its obtained straight from the plant and does not involves any burning of material 1. Biodiesel can be taken as an example for this type of form. It is extracted from vegetable oils or animal fats 11.Gas form its obtained from organic waste such as dead plant and animal wastes when the organic material br eakdown naturally without the need of oxygen 12. Biogases consist of methane that is essential in terms of natural gas 12.3.1.2 Application of biomass widely used in transportation in the form of gasesElectricity generation plantsGas produced from the biomass gasifier must be cleaned first before cooling it down and use it as a fuel to run an IC engine that is coupled together with the generator 13.Heat applicationBiomass is used as a fuel to provide energy for the fuel-fired furnace that is often used for mellow end outputs such as13 Forging furnaceOvensKilnsDryersSmall boilers assume fire process heaterRe-rolling mills3.1.3 Benefits of biomass energyBiogases that are used as fuels gives more mileage for cheaper price compared to fossil fuelsEnergy from biomass has got no ending to it since human throw wastes in daily nucleotide and animals also constantly produce muckEnergy gained from burning the wastes releases carbon dioxide to the atmosphere and the carbon dioxide that is re leased from the burning is useful for the plants in terms of photosynthesis process.Each agricultural has their wastes in terms of plants, animals dung and garbages, these materials is available locally. This can reduce the need for foreign investors in the country thus improve the nation economically as wellBiomass in mass production can reduce the increase in global temperature significantly.3.2 Ocean energyOcean energy is gained from the sea. there are two types of energy gained from the ocean such as thermal energy and mechanical energy 15. Thermal energy is gained by the difference in temperature amidst the warmer surface of the ocean and the deep cold ocean water 15. Mechanical energy is gained from tidal and wave that is used to open the turbine to provide electricity in most of the power plants available 15.3.2.1 Types of energy gained3.2.2 Thermal energyThe difference between the temperatures should be around 38 Degree Fahrenheit in order to build a power plant that can fully utilize this temperature difference to make energy 16. There are 3 types of bicycles abstruse in electricity innovation system from the heat energy such asClosed cycle The heat at the surface of the ocean water is used to vaporize an ammonia type of fluid which has low boiling point and the vapor expands to turn the turbine to produce electricity 15.Open cycle The sea water in this case is kept at low pressure in order to force it to boil at low temperature and the steam produced from the sea water is then used to rotate the turbine to activate the generator to produce electricity15.Hybrid The combination of both(prenominal) open and closed cycles is used to rotate the turbine in a most economical focussing 153.2.3 Mechanical energyTidal energy its gained as the earth rotates and the gravitational pull of the moon. The principle of tidal energy is when the tides is at spicy point the water is trapped in the dam and as the tides began to reach the low point, the trap ped water is released to rotate the turbine at high speed to generate electricity15. The concept is similar to hydroelectric power plants 6.Wave energy Existing kinetic energy from the movement of the waves is used to power up the turbine 15. The concept is simple that the waves from the ocean comes into the chamber from the right, as the rise of the waves will force the air to release from the chamber and the released air is the one that will rotate the turbine to provide electricity as shown in the figure 1 below16. The higher the waves, higher are the rotation of the turbine.http//www.energyquest.ca.gov/story_old/images/chap14_wave_2007.gifApplication of wave energy 163.3 Hydrogen and fuel cells energyHydrogen best identified as the simplest component 18. One proton and one electron are the sub elements inside an atom of enthalpy 18. It has a limitation is that it doesnt appear by its own in the earth. Hydrogen atom always combined together with other elements such as water 1718 . The molecular(a) weight of hydrogen is 1kmol and the lightest weigh among all the other natural components available in earth. Hydrogen can be separated from hydrocarbon by heating process and this is called reformation process 18. Electric current also used to separate hydrogen from water and the separation process is called electrolysis 18.Fuel cells function is to convert hydrogen to electricity directly without any other processes in between 18. Reformation of methanol, gasoline and natural gas can provide hydrogen for the usage of fuel cells 18. Methanol can be used directly for some fuel cells without any reformation process 18.3.3.1 Applications of hydrogen and fuel cellsNASA used liquid nitrogen as a fuel for the space shuttles and other rockets. Liquid nitrogen does not emit any harmful material after the combustion 18. The product of the conversion by hydrogen fuel cells is pure water that is used as drinking water by the astronauts 18.Hydrogen powered vehicles is among the growing applications of energy since hydrogen fuel cells capable of providing power for buses21. Fuel cells also can provide electricity for a residential housing area that is big as a traditional AC unit 21. It can operate 24 hours a day and 7 days a week.3.3.2 Advantages of fuel cellsEfficient conversion of energy from hydrogen to electricity without any combustion taking place and the byproduct is water1920The noise level created from an operation of a fuel cell comparatively much more quiet than the conventional motors20Easier maintenance since less moving parts20Life span is longer than a battery since it has no memory strength when its refueled10The source for fuel cells are hydrogen and it is available with water20Can reduce the nations usage of fossil fuels since fossil fuels come at higher price than hydrogen that is naturally available in the earth 20.3.4 Geothermal EnergyGeothermal energy is a form of thermal energy stored by generation of heat from radioactive decay of minerals occurring inside the earth (80 percent) and from the original formation of the planet (20 percent).6 Due to the temperature differences between the earth meaning and surface, continuous heat transfer occurs from the core to surface. Radioactive decaying of natural materials such as uranium and potassium that occurs at the core creates a temperature reaching over 5000 course Celsius and very high pressure.7 This high temperature and pressure causes melting of surrounding cooler rocks and these results in the formation of magma. This magma then heats up the rocks and water in the crust which can go up tp 370 degree Celsius.6 In the range of 10kilometers of earth surface contains heat energy that is 50000 times more than all the oil and natural gas sources in the world.7 The typical place that usually spots geothermal activities is regions with active volcanic activities. This usually occurs at places where the earth crust is thin enough to let the heat out. Earthquake a nd magma movements breaks up the rocks covering and allows water to circulate, producing natural hot springs and geysers as the heated up water reaches the surface. As these hot and pressured water forms a reservoir type of containment underground, come up are usually constructed to harvest electricity or heat.3.4.1 ApplicationsSteam produced from the reservoir containing pressured and hot water are usually used to power turbines in power plants that generates electricity (Steam Turbine), while other power plants uses the hot water in the reservoir to boil a working fluid that vaporizes and moves a turbine. Heat produced by hot water near to the earth surface can be directly used for heating purpose. The applications that utilizes these direct heat includes heating buildings and homes purpose, growing plants in greenhouses, drying crops, heating water at fish farms, and also in pasteurizing milk processes at milk industries. This is done by using geothermal heat pumps. There is als o formation of hot dry rocks, usually 4-10kilometers from earth surface. Technologies is existing to inject cold water onto these hot dry rocks, circulating them through the cracks of the rocks and conscription back the heat from another well located at the end of the water circuit.5http//www.bbc.co.uk/schools/gcsebitesize/science/images/131_geothermal_energy.gifWater pumped down through injection well and collected at production well.http//www.ucsusa.org/assets/images/ce/geopower3.gifHow geothermal heat used to power turbines.3.5 HydropowerHydro means water, so hydropower basically is the power that derived from the force of moving water and generates electricity at damn by water fall throughout the turbines. 22 The fall of water and movement is part of a constant ordinary cycle known as water cycle. Water in the earths ocean and rivers evaporates by energy from the sun and draws it ascendant as water vaporization. Once the water vapour reached the cooler air in atmosphere, it a utomatically abbreviates and forms as clouds. 23 Hence, the moisture fall to earth as rain and fill the water in oceans and rivers. The moving of water from higher ground to the lower ground with the gravitational force and it drives the water extremely powerful to assist generates electricity for daily usage of human being.23 Hydropower is a one of the worlds biggest source of renewable energy and play important role or facing challenges during period of climate vary. 24 Hydropower also is considering clean energy source because it does not release any toxins to damage the environment. 25Figure 3.1 Water cycle plot3.5.1 Types of HydropowerHydropower is primarily used to generate electricity. There are few types of hydropower which is general usage in world.Micro hydro provide few hundred kilowatts to remote villages, homes and small industries.26Pumped-storage hydroelectricity stores the water that has been pumped during low demand and generates it when demand is high.26Run-of-th e-river hydroelectricity it will intrigue the kinetic energy in rivers without using dams.26Conventional hydroelectricity power comes from the potential energy of dammed and water drives the turbine to generate electricity.27The most common type of hydropower that has been used is conventional hydroelectricity known as hydroelectricity power plant which is uses a dam on a river to store water in a reservoir. This power station is usually placed in hill areas so can build dams easily and can obtain larger water reservoir and generate huge meter of electricity. 283.5.2 How is hydroelectricity power produced?http//cwc.gov.in/Kids%20Corner_files/hydropower.gifFigure 3.2 Simple Hydropower station diagramIn hydropower station, the potential energy that stored in body of water at a given summit is converted to kinetic energy which is used to rotate the turbine and produce electricity. 28In the generation of electricity by using hydroelectric power, water is accumulated or stock up at hi gher level and guide descending through large pipes to lower level known as penstock. 29 Once the water reaches the end of the penstock with higher pressure it will hits and drives the turbine to create mechanical energy from kinetic energy. Turbines rotate the connected to shaft which is turn the generator and replace mechanical energy to electrical energy. 9 Inside the generator there is rotor that covers by turbine. Large electromagnets are attached to the rotor located within coils of cop wires called as stator. Flow of electrons is formed in the coils of stator when a generator rotor spins the magnets. 31 This produces electricity that can be step up in emf through the station transformers and centre cross transmission lines. thus, transmission line conducts electricity from hydropower plant to the distribution system. There are certain advantages and disadvantages of using hydroelectric power stationAdvantagesIt is constantly renewable remaining to the habitual nature of t he hydrologic cycle.The water that been used for generation of electricity can be utilize for irrigation, boat and fishing, kayaking and etc.Fuel is not burned so there is minimal pollution and no waste is producedUsing water to run the power plant that provided free by natureDisadvantagesOnly at limited places hydropower plant can be constructed.Dams are expensive to build.Possibility of dam collapsing3.6 Solar energySolar energy is the radiant energy emitted by the Sun that is converted into thermal or electricity energy for homes and industry usage. The amount of energy falling on the earth is given by the solar constant, but very little use has been made of solar energy. 32 Renewable and sustainable energy source such as solar energy make use of it around the world to produce electricity for number of different purpose and its use is both environmentally-friendly and cost-effective over the long term. There are varieties of technologies that have been used to take benefits of s olar energy. Types of technologies such as photovoltaic system is common have been used to develop solar energy for daily and powering legion(predicate) applications. 33photovoltaic system (PV) is solar cells or panels directly convert temperateness into electricity. 34 The conversion of sunlight directly into electricity (DC) will be done by solar cells. Electricity from solar cells is stored in the battery for instant or future usage and where an inverter is required to change the Direct Current (DC) to alternate Current (AC) to power the most AC appliances. 35 Photovoltaic system solar cell made of semiconducting materials that related to those used in computer chips. Once the rays are engaged by these materials, the solar energy knocks electrons loose from the atoms, via allowing the electrons to flow through the material to produce electricity. This process of converting light (photon) to electricity (voltages) is called as photovoltaic (PV) effect. 36 The simple of photovol taic (PV) system gildd in figure below that can explain about it.A diagram of how the components of a PV system interact with each other.Figure Simple Photovoltaic (PV) system with componentsThe electricity that generated can be stored or directly utilize by photovoltaic standalone system, or a huge electricity grid powered supplied by central generation plants (photovoltaic grid-tied system), or else joint with single or numerous domestic electricity generations to supply into small grid (photovoltaic hybrid system). 37 Supplying of DC and/or AC electrical load that operate independently of the electric utility grid is designed by standalone photovoltaic system. Direct-coupled system is of the simplest type of standalone photovoltaic system that the DC output of a module or set is directly connected to a DC load (figure). 38 When there is no electrical energy stored in batteries in direct-coupled system, the load can operates during the sunlight. So, common applications that used for example water pumps, ventilation fans and small circulation pumps for solar thermal water heating systems are appropriate. 38A diagram of a stand-alone photovoltaic system.Figure Direct coupled PV systemHybrid system only integrates more than one generating source, which may use an engine-generator, wind, or utility power as a ancillary power source. Initially the battery store is recharged by the photovoltaic system once insufficient the generator charges the batteries.Solar Hybrid SystemFigure Photovoltaic hybrid systemGrid tie photovoltaic system is deliberate to work with utility grid power. Direct Current (DC) power from the Photovoltaic roam into Alternating Current (AC) power is converted by the inverter. AC appliances or local utility company can make use of the direct AC power.Solar Grid-Tie SystemFigure Photovoltaic Grid Tie system3.7 Wind EnergyWind energy is the renewable power or energy which comes from the air that flowing across the earths surface. Wind energy is a converted form of solar energy. 40 Wind is exist due to uneven heats of the atmosphere by sun, the mental defectiveness of the earths landscape and rotation of the earth.41 Movement of air from region of higher pressure level to region of lower pressure level is also known as wind. When hot air increases, the atmospheric pressure will reduce at earths exterior, and the cooler air will travel in to fill up the void. In fact, flow of wind patterns are personalized by earth landscape, vegetative cover and bodies of water. One of the fastest growing sources of electricity and fastest growing markets in the world today is wind energy because is green power, sustainable, affordable, and economic development. 42 In wind turbines there are consist of horizontal and vertical axis wind turbines been designed for rotation function.3.7.1 How a wind energy or wind turbine is work?Terms of wind energy or else wind power illustrate the generation of mechanical power or electricity by using w ind. Air has mass when it is in motion, and it contains the energy of that motion, known as kinetic energy. 40 Therefore wind turbines are usually use to harvest the kinetic energy and convert it by using inverter into utilizable which can provide electricity for home, business line applications and for sale to utilities. Wind turbine also produce mechanical energy that harvested from kinetic energy to drive machinery, for instance grinding grain and pumping water, the device called as windmill or wind pump in rural place. wind energy diagramMost common method to generate electricity is by using wind turbines. Figure 1 is explaining the simple understand on working principle of wind turbines. Explanation from the figure 1, wind will turn the large turbine blades the turning energy will spins a generator shaft and produces electricity. The electricity that produced by wind turbine is Direct Current (DC) and it cannot use because household appliances and use Alternating Current (AC). Hence, inverters connect to wind turbines to the mains power of a building and used to convert the DC electricity into useable AC electricity. 43 Small-scale of wind energy does not use inverters, as an alternative using the wind energy electricity can be charge batteries, connected to buildings main power or else connected to national power grid. 44AdvantagesThere are no fossil or fuels required to generate electricity 45Wind energy does not befoul at all so does not harm environment or discharge any toxic gases7Wind energy directly can be used as mechanical energy47DisadvantagesOnce there is no wind, solar energy or geothermal energy use as alternative way to generate electricity 48Need expensive storage throughout peak production time.49Requires large scale area to build wind farm.494. ConclusionGreen energy is the only visible solution so that the future generations are not compromised

Pfizer Drug Suit :: essays research papers

Pfizer and the Nigerian Trovan SuitThere has been a controversy about the experimental testing of the drug Trovan (trovafloxacin), by Pfizer, a major pharmaceutical company. Pfizer held clinical trials of the drug in Kano, Nigeria, during the 1996 epidemic of bacterial meningitis. The experiments were conducted on 200 children and were said to be successful. Recently, 30 Nigerian families of the children use in the experiments filed a lawsuit against Pfizer claiming they had violated laws by not obtaining permission from the families. (Reliefweb) This lawsuit is unprecedented. I believe Pfizer handled this experiment with good intentions and the press, namely the Washington Post, has unfairly portrayed them.The Food and Drug Administration (FDA) has recently restricted the use of the antibiotic, Trovan, after it has been proven to cause liver failure and a small turning of deaths when prescribed for many types of infections. Doctors were warned to reserve the use of Trovan for use only in the interposition of patients who meet very specific requirements. (Branch Law) Although it is harmful when used for certain ailments, Pfizer reports that Trovan has proven to be effective in treating meningococcal meningitis. This was determined during the experiments in Nigeria which were supervised by both American and Nigerian doctors. (Pfizer)This experiment took place in Africa because of its recurring meningitis epidemic, which kills thousands of people. Pfizer took the fortune to compare Trovan with ceftrixone, which was the commonly used drug at the time, to prove its effectiveness. One hundred patients were given Trovan and another 100 ceftrixone. In each group cardinal percent of patients survived. This mortality rate of 6% for both patient groups was lower than that seen in patients with non-epidemic meningitis (range 6-10%), and lower than the overall fatality rate for this particular epidemic (10-30%).(Pfizer) The incidence of side effects while using Trovan was not any higher than with ceftrixone. Oral Trovan proved to be a very safe, useful and promising treatment for this disease as compared to using other methods, which had to be given intravenously and could spread hepatitis or HIV. Pfizer states that, The trial was designed and conducted in accordance with good health check practice and ethical norms. They also said that both the Nigerian Ministry of Health and a local Nigerian ethics committee approved the experiment and a copy of this was sent to the FDA. Prior to treatment, informed consent was obtained.

Regulating Prostitution Essay -- Prostitutes Ethics Morals Sex Essays

Regulating ProstitutionHistorically, although prostitution has been viewed as a threat to the moral order and a danger to public health, the state has tended to legislate for the decree of prostitution, rather than introducing measures focussed on its elimination. Even early Christian societies did not seek to eliminate prostitution, with the Church fathers justifying this stance by asserting that Sewers are undeniable to guarantee the wholesomeness of palaces. (quoted by de Beauvoir, 1974, 618). St Augustine was adamant that prostitution should be recognised as a necessary social evil, arguing,Suppress prostitution and capricious lusts will debauch society. (cited in Roberts, 1992, 61).His stance was predicated on a belief in mens sexual appetites necessitating access to sexual outlets outside of marriage. In order to hamper them committing adultery and threatening their marriages, society should facilitate mens access to prostitutes. It follows from St Augustines argument that two separate classes of women were required - good, virtuous, sexually faithful wives to assistant mens procreative needs within marriage, and prostitutes who would cater to their desires and pleasures outside of marriage. Such thinking views prostitution as a necessary social evil, and reinforces the bloody shame/whore dichotomy. Given the fact that mens demand for prostitution services has not abated through the ages, the historic response has been to continue to seek its legislation and control rather than its eradication. For instance, in medieval England and Europe the preferred way of regulating prostitution was to restrict prostitutes to working in certain districts and/or requiring that they tog in particular, identifiable, styles. Thus in Paris, prostitutes were confined to working in brothels in particular areas of the town and were required to wear armbands, dye their hair, or in another(prenominal) ways distinguish themselves from respectable society matrons (Bulloug h and Bullough, 1987, 125). Women who violated such codes of behaviour could find themselves expelled from that district, literally being run out of town. Confining the sex intentness to specifically designated areas was also seen as economically advantageous in that it enabled municipal councils to share in the profits (Roberts, 1992, 90).
