MPC Relationship With Its Large Global Customers Case Study
MPC Relationship With Its Large Global Customers - Case Study Example Moreover certain value-added services that were provided to the clients which helped in improving and bolstering its relationship with the clients. The relationship between the suppliers and the clients is guided by the bargaining power of the supplier/the buyer. The supplier dictates the shots if it has a higher bargaining power and conversely, the client has an upper hand when it has a higher bargaining power. In this case, there are only a few players I the market. Moreover, with high entry costs, the entry of new players is quite difficult. This gives MPC a higher bargaining power. The bargaining power also defines the value division. The bargaining of the supplier with the client the amount the supplier gets for providing its clients with the important resources. The figure above depicts the relationship between the client and the supplier using a line segment. The top level of the line represents the value that has been received by the buyer. This value is equal to the willingness of the buyer to pay for the goods or services minus the amount that has been paid by the organization. The middle segment represents the value that has been captured by the firm. The lowermost position of the segment defines the value that has been acquired by the supplier. (Brandenburger M, Stuart HW, n.d.). The figure above gives a model on how suppliers should rate its clients. MPC must use the model stated in the figure to analyze its relationship with the clients. It should divide its clients on the basis of relative value and its attractiveness. MPC can also use its rapport with its clients to set up bases in the low-cost destinations. This would allow the company to make its presence in those markets while creating entry barriers for the new players. This would also give MPC a foothold in a new and emerging market. The firm can employ the model of Brandenburger and Stuart for creating new value in their product offering. This model is based on the concepts of valueà creation and added value which represents the size of the profit to be shared and how to share that profit respectively.Ã

Chinese Culture Essay Example for Free
Chinese Culture Essay The climate and temperature of China varies throughout the area of the country. Most of the country lies in the temperate belt, but the southern most part lies in the subtropical belt while the northern part is in the sub arctic belt. There is usually a lot of rain in the summer, and very little in the winter. China has the largest agricultural output in the world, while only cultivating 15% of its total area. Rice is Chinaââ¬â¢s most harvested crop, while wheat is second. China also produces potatoes, other vegetables, and some fruits. By the end of 2000, China had 633 different cities, while 13 of them had a population of two million or more. The three biggest Chinese cities are Shanghai, Beijing, and Chongqing, in that order. Hong Kong is inside China, but isnââ¬â¢t considered part of the country. Confucianism used to be the main religion in China and help shape its history. However, Buddhism has the most followers and biggest influence in China than any other religion, now. Some other major religions throughout China are Taoism, Islam, and Christianity. Most people in China, now, play sports just like us such as ping pong, soccer, and badminton. These types of sports are fairly new to China, while different types of martial arts have been around much longer than team sports. China is a communist state. This means that everything is ruled and owned by the government. There is no private ownership, and all goods are shared by the people, who are all equal. Chinese education is required and free for ages 6 ââ¬â 15, and can be continued longer if the person wants to and can afford it. Most of the jobs throughout China are related to agricultural businesses, or they do cheap labor for companies all around the world. The employment rules in China are much more relaxed than the U. S. so big corporation usually have Chinese factories make their goods for much cheaper. Stir fry is the most common cooking technique throughout China. It requires a small amount of oil in a heated pan, and the ingredients of the mea, usually vegetables and meat, are put into the pan and cooked until ready. The most used cooking tool is the wok. It is pretty much like a pan with rounded edges for stir frying. Chopsticks are by far the most used eating tools of the Chinese people, just like our forks and spoons. Chinese meals almost always have rice or noodles. The is usually vegetables in the meals, which could be many different types, such as broccoli, bamboo shoots, mushrooms, cabbage or eggplants. The meat is usually chicken, pork, or fish. Chinese meals are eaten pretty much at the same time as out meals. Breakfast is in the morning, lunch in the afternoon, and dinner is at night. There are much unusual eating etiquettes that must be followed in China. One is that your tea can never be empty. The host will always be refilling their guestsââ¬â¢ cups, and the guests must tap their cup on the table as a showing of thankfulness. Another eating etiquette is that, when out with a group of people, you must order an even number or plates, even if there is an odd number of people, because odd numbers symbolize death.

Preheat oven to 325 degrees Fahrenheit (162. 5 degrees Celsius). 2. In a large bowl, sift the flour, baking powder, baking soda, and salt. In a medium bowl, use an electric mixer to beat the butter or margarine, shortening, and sugar. Add the egg and almond extract and beat until well blended. Add to the flour mixture and mix well. Note: The dough will be crumbly at this point, but dont worry that is what its supposed to be like. 3. Use your fingers to form the mixture into a dough, and then form the dough into 2 rolls or logs that are 10 to 12 inches long. Wrap and refrigerate for 2 hours (this will make it easier to shape the dough into circles). 4. Take a log and lightly score the dough at 3/4 inch intervals so that you have 15 pieces and cut the dough. Roll each piece into a ball and place on a lightly greased cookie tray, approximately 1 1/2 inches apart. Place an almond in the center of each cookie and press down lightly. Repeat with the remaining dough. 5. Brush each cookie lightly with beaten egg before baking. Bake for 15 minutes to 18 minutes, until golden brown. Cool and store in a sealed container.

The Performance Of The Foxconn Business Commerce Essay
The Performance Of The Foxconn Business Commerce Essay Foxconn Technology Group, a subsidiary of the Hon Hai Precision Industries Ltd. and is one of the worlds largest electronics manufacturers. It ranks 112th among Global Fortune 500 Companies. Currently, Foxconn has a workforce of 900,000 workers all over China. The company plans to expand its workforce to 1.3 million people by the end of 2011 (Culpan, 2010). It manufactures hardware for a prominent list of clients, including Apple, HP, Dell, Nokia and Nintendo. Despite the fall of profit margins over past few years, Foxconns business has been growing. This implies that Foxconn will keep lowering labor costs to maintain its dominance in the industry. The recent uproar in media about Foxconn has not been because of its huge workforce or its profits. Rather, it is the 17 young Foxconn employees who committed suicides between January and August 2010 that has brought into light the dilemma of frontline employees at Foxconn and other such factories. The suicide rate for China stands at 12 for every 100,000 people per year. With a workforce of 420,000 and 13 suicides this year, the suicide rate at Foxconn is approximately one-quarter the national average (Mimi, 2009). This paper will elaborate on what the media have reported and relate the data to employment relations. Wages and Working Hours Foxconn claims that it is compliant with local laws. But, research studies conducted by SACOM (Students Scholars Against Corporate Misbehavior) have found that Foxconn has been a regular violator of labor laws. Many hidden facts relating to employment relations are discussed below. Workers were kept uninformed about wage increase plan When the suicide cases reached a climax in May, Foxconn apparently increased wages twice, but there was no formal announcement. Also, details about the conditions under which workers can benefit from this pay rise, like seniority or type of contract were not discussed. Basic wage is just slightly more than minimum wage and far below living wage The basic wage of frontline workers at Foxconn is only CNY 100 more than the minimum wage (SACOM, 2010). According to Foxconn management, the purpose of the wage increase plan was to stabilize the workforce. But the fact is that the basic wage was insufficient for workers to maintain decent living standards in Shenzhen. Also, basic wages in Tianjin, Wuhan and Kunshan lag far behind the standard wage, which makes it extremely difficult for workers to live in such expensive cities on such small incomes. Excessive overtime Marxism came into existence through Marxs observation a known writer and theorist who opposed capitalism while capitalism was in its infancy, his theory was named the Marxist theory. To Marx employment relation was a major way of understanding capitalism. He was like an opposition force for the employers, he disputed the divisions that were created in the industrial society through competition between the two classes (employers and the employees). He was of the idea that since employees had to do meaningless jobs it created low esteem, morale and low motivation amongst the employees. His approach created the thought that conflict will persist in the employment relations and no solution will be able to resolve it completely, and the only basic changes in the economy, such as overthrowing capitalism, will help in creating a socialist economy, however, China is already a socialist economy and state. One could argue that because China is a communist state, it operates on socialist values and employs Marxist philosophies in order to improve the wellbeing of the Chinese people. However, from the Foxconn example, we can see that this was not the case and this raises the question of if the Marxist theory really has any relevance in improving self esteem, when Foxconn has violated several Labor Laws . In any working environment, overtime work should not be more than 36 hours per month (article 41) (SACOM, 2010). For example, engineers at Integrated Digital Product Business Group (IDPBG) of Foxconn in Shenzhen, who were involved in production of the first generation iPad, worked whole weeks, including Sundays and had only one rest day every 13 days plus they did not even receive any overtime premium for weekends. There are other departments where workers work overtime for about 140 hours a month and have no day off at all. Deduction of overtime premium According to workers at Foxconn, calculation of working hours is incorrect. Foxconn uses Comprehensive Calculation of Working Hours System, which does not recognize monthly overtime beyond 80 hours (quote) and hence, workers are not paid for those hours.Ã Also, workers complained that the newly introduced overtime control is actually misleading in the sense that overtime does take place, but it is not recorded or paid as such. Apart from all this Foxconn employees are made to attend morning assemblies, end-of-work-shift assemblies and weekly meetings during which the management talks about expected deliverables, work targets and discipline, but they do not receive compensation for the time spent in these compulsory meetings that may consume up to one hour a day. Time spent in training is not fully paid either. As a result, workers do not earn more than before the June 2010 wage increase. Management A close analysis of the management practices and workers criticisms about the management at Foxconn is indicative of the fact that a military-style, punishment focused working management followed at the company for its workers is another factor that might have contributed to suicides at Foxconn. A culture of obedience is forced on workers from the first day of their employment. They are badly treated during recruitment procedures; they are not allowed to questions during their orientation trainings; they are punished for all kinds of misconduct, ranging from as big as not meeting their daily deliverables to as minute as taking too much time in bathroom. Reward system Workers are deprived of production bonus, which is given twice a year, if they have declined overtime work or taken sick leave. It seems that there are no set terms for a bonus; it is exclusively at the discretion of the management. All these factors reflect the authoritative nature of Foxconns management. Foxconns military-style corporate philosophy is also reflected in one of the sayings of Foxconns billionaire CEO Terry Guo democracy is the most inefficient thing in the world (Chang, 2010). This explains why Foxconn regime excludes any say by workers and why it is so anti-democratic. Trade Unions Theories kept evolving as the size and scope of businesses expanded, taking into consideration technology and the nature of work of the employees. One of the theories that came about was the pluralist theory, which acknowledged the complex situations such as conflict of interest between the management and the employees. It suggested that these kinds of complex situations could only be resolved through the involvement of government. However, because China is a communist state, trade unions struggle to exist and therefore pluralism cannot and wont be adopted. Investigations at Foxconn reveal that workers have no confidence that the state-run trade unions will defend their rights for very obvious reasons. First, these unions are usually silent on working conditions of the company. Instead, at the companys morale-boosting rallies, the union officials glorify Guos image and Foxconns corporate image by displaying portraits of Guo and singing his praises. Second, these trade unions consist of few young members and majorly of senior management officers. Apparently, the union members tend to please the management in order to secure their jobs. Last, the trade union committee is not democratically elected. This is indicative of the political power exercised by Foxconn and its higher management. Health and Safety Most of the workers are not aware of the damaging effects of chemicals they use and of the precautionary measures they must follow before working with dangerous materials on the factory floor. Many of them suffer from threat of occupational diseases. Under the increased pressure, 12.7 percent of workers experienced fainting spells, 24.1 percent of female workers had irregularities in their menstrual cycle and 47.9 percent of workers complained of mental stress. This clearly shows the lack of training for workers on occupational health and safety. Moreover, denying protective equipments and health examinations to workers shows managements informed negligence in following safety standards for workers. Relocation Plans Currently, Foxconn has a huge workforce of around 420,000 in Shenzhen plant alone. In the result of series of suicides, Foxconn announced its plan of relocating its production to central, western, and northern China, where labor is plentiful and official minimum wages are lower than in other areas. Workers were again uninformed of the details but anyway, they had no choice but either relocate or resign. A serious implication of this move is that the announced wage increase for the Longhua workers in Shenzhen will become irrelevant. Social Factors Though Foxconn offers accommodation for workers, but it is more like a prison to them. As a result of their low pay, most workers are forced to live in crowded factory halls. On average, each worker has a space of about two square metres. There is no social interaction among roommates because of their different backgrounds and shift timings. Social isolation in Foxconn is regarded as one of the chief causes of the suicides. A prison-like safety mesh is installed in every hall building in many facilities to prevent workers from jumping. This indicates that management is aware of the potential intentions of the workers. All the factors discussed above help us realize the physical, social and psychological agony workers at Foxconn go through each day. These factors highlight the underlying causes of the dilemma of workers at Foxconn and at other such companies. Illegal and unethical labor practices followed by Foxconn, lack of basic democratic rights for workers, monopolistic capitalist mode of production by translational corporations in global supply chains, lack of auditing by the government of the employment terms and practices followed by companies, discriminatory characteristic of Chinas urban household system, lack of government support are some of them. Conclusion The essence of all these traditional theories of management styles is that there exists a single, best approach to management, and the research was aimed at finding this best approach. One of the recognized theorists was Fredrick W. Taylor. His purpose and idea was to maximise efficiency, he believed that the principal object of management should be to ensure maximum prosperity for the employer, coupled with the maximum prosperity for each employee. He considered that the best approach was for the employee to fulfil optimum goals, which would result in higher wages for them, and managements gain will be higher productivity. Therefore the employee himself will work harder and try his level best to produce more since he is getting financial benefits for doing so, this was his differential piece-rate system. This clearly was not the case with Foxconn, as demonstrated by the evidence highlighted throughout the body of the paper. In the past few years, manufacturing facilities or so called sweatshops have started following labor laws but at the same time to make up for the loss, they have developed strategies to speed up the production in factories. As a result, production targets keep soaring and labor exploitation does not stop. Thus far Foxconn and its high-profile customers including Apple, HP, and Dell have failed to effectively address underlying labor issues at the Foxconn production facilities. But, Foxconn is not the only one to be responsible; these other big electronic brands, which place orders with Foxconn, are equally responsible for the tragedies. By threatening to shift their orders, they force their suppliers in China to lower wages, prolong working hours and intensify workloads and thus directly pressure the workers. Clearly, all these brands are making huge profit at the cost of the workers miserable lives. It is apparent that the grievances of the workers cannot be addressed by Chinese labor laws alone. It is required to reveal the actual working and living conditions of workers at Foxconn to gather public support for their struggle against their plight. Pleading companies to abstain themselves from violating labor laws is futile; instead, people must urge concerned organizations, consumers, investors, and the government to join the workers to pressure electronic factories to improve working conditions and employment relations in the electronics industry. Also, to fight for workers rights, effective trade unions must be formed by holding democratic elections in accordance with the Trade Union Law in China. Foxconn needs to reform its structure. There is a need to meet the political requirements, which calls for better wages, recognition of workers rights and the development of hi-tech industries that will create better living standards for workers. Foxconn must address communication gap between management and the labor and focus on employee satisfaction, rather than solely company profits. Workers must be kept informed about their rights, about the relocation plans well in advance, about any wage increase plans and be provided with the details of the terms and conditions followed for giving bonuses. These are just basics principles of employment relations, which Foxconn have not come close to meeting.

kung san :: essays papers
kung san Among the many cultures in Africa, one of the most well known cultures would be the Kung San. The Kung San are a very unique culture and are the most studied foraging society in the world. As with numerous other cultures around the world, the Kung San are faced with many problems. But one problem the Kung San don't face is that of being a nonentity, partially because of the popularized view of the Kung San shown in the movie The Gods Must Be Crazy. The Kung San are a hunting and gathering people living in southern Africa. Kung San are a varied people in terms of looks and language, and include people living Angola, Botswana, Zambia, and Namibia. The Kung San, like many human groups, have a rigid sexual division of labor, with women doing most of the gathering, food preparation and child care, and men doing hunting and some complementary gathering. There does exist a limited socioeconomic hierarchy by age, with adults controlling more resources and manufactured goods than children. The Kung San usually eat small meals during the day and eat a large supper with the whole family in the evening. Water is a limiting factor in the Kung San environment. The Kung San will disperse in the wet season, and aggregate in camps in the dry season around the few permanent water holes. A Kung San encampment consists of grass huts arranged roughly in a circle, constructed around an area of clearing in the center; these huts are constructe d quickly and rarely used for more than a few months at a time. The Kung San maintain a level of egalitarianism so that no one person is revered more than the next and so that no one thinks they are any better than the next. In the Kung San culture, many are married as young as eight years old in order to keep conflicts and extramarital relations down to a minimum. One of the Kung San's favorite activities is to sit in the shade talking amongst themselves. They are afraid of angry words and violence so the occasional dispute is worked out before it becomes a major one. Since competition might bring dispute, they try to live as equals. The Kung San effectively employ talking and joking to

Modelling and Forecasting Electricity Consumption of the Philippines Essay
In the Philippines, electric power is becoming the main energy form relied upon in all economic sectors of the country. As time goes by, while different establishments and properties were built and developed, the demand for domestic electricity consumption within the country accelerates. Energy consumption is an important index of the economic development of a country. Rapid changes in industry and the economy strongly affect energy consumption. According to the International Energy Annual (IEA) in the year 2004, the Philippines had total installed electricity generating capacity of 15.1 gigawatts (GW). The country produced 53.1 billion kilowatt-hours (Bkwh) of electricity in 2004, while consuming 49.4 Bkwh. Conventional thermal sources make up the largest share of Philippine electricity supply, comprising more than 65 percent of the total in 2004. However, the Philippines is also the worldââ¬â¢s second-largest producer of geothermal energy. Despite several electricity sources, there are still bunch of problems that occur such as electricity shortage and high price somewhat due to increase of demand and company expenses. The Philippines is not just the sole country that experiences these specific dilemmas but the other countries in Asia like Lebanon and Saudi Arabia, and the entire world too. This pushes researchers and experts to study the consumption movement from the past years in order for them to learn its behavior and suggest a method to help prepare the power companies and to prevent uncertainties that might happen in the near future. Through the years, there are many ways and methods developed by the experts and one of them is modeling and forecasting. Modelling electric energy consumption is useful in planning and distribution by power utilities. Modeling is a process of generating abstract, conceptual,graphical and/or mathematical models. Models are typically used when it is either impossible or impractical to create experimental conditions in which scientists can directly measure outcomes. In the field of energy use direct to electricity, modelling is a very important factor in forecasting the next set of electricity consumption. There are plenty of techniques and mathematical methods which are already used and proven effective in determining the energy consumption such as Multivariate regression ââ¬âanalysis, neural networks, autoregressive, and many more. Nowadays, time-series analysis was also used in the electric energy consumption modeling and forecasting. In statistics, signal processing, and mathematical finance, a time series is a sequence of data points, measured typically at successive time instants spaced at uniform time intervals. Based on Investopedia (2012) it provides another modeling approach which requires only data on the modeled variable, thus saving the user the trouble of determining influential variables and suggesting a form for the relation between them. For instance, measuring the value of retail sales each month of the year would comprise a time series. This is because sales revenue is well defined, and consistently measured at equally spaced intervals. Data collected irregularly or only once are not time series. Also, according to Austrilian Bureau of Statistics (2005) an observed time series can be decomposed into three components: the trend (long term direction), the seasonal (systematic, calendar related movements) and the irregular (unsystematic, short term fluctuations). Models for time series data can have many forms and represent different stochastic processes. Some other applications of time-series analysis are in macroeconomics and finance. As of now, modelling and forecasting is of its highest peak of achievement and significance of the modern society especially in aiding certain dilemmas in electric consumption. Objectives 1. To formulate a mathematical model for the electricity consumption of the Philippines. 2. To forecast the Philippinesââ¬â¢ monthly electricity consumption for the next three years. 3. To evaluate the formulated model in forecasting the electricity consumption. Significance of the Study The goal of this study is to be able to forecast the electrical energy consumption of the Philippines for the next three years through formulating a model acquired from the data by using time-series. This information can contribute much to the power supply companies of the Philippines in order for them to determine the set of electricity consumption for the coming years. The forecasted result will help them plan and prepare for whatever might happen in the future years specifically in addressing the electricity shortage. Scope and Limitation The study focuses primarily in modelling the electricity use of the Philippines by using the time-series analysis. The study is narrowed to the forecasting of the monthly electricity consumption for the next three years of the entire Philippines. The data used in modelling is based on the 1999-2011 record. Review of Related Literature Modelling and forecasting electricity consumption of Malaysian large steel mills This study attempts to model and forecast the daily maximum demand of Malaysian large steel mills and the annual maximum demand contributed by these steel mills. It attempts to combine both the top-down and bottom-up approaches to forecast the daily and annual maximum demand of the steel mills. The top-down approach uses regression analysis to forecast the annual amount of electricity consumption of the steel mills. The bottom-up approach uses the Model for Analysis of Electric Demand Electric Load (MAED_EL) to convert the annual steel mills electricity consumption (which was earlier obtained from the regression model) into hourly load of the steel mills. The proposed method shows good forecasting accuracy, with weekly Mean Absolute Percentage Error (MAPE) of 2.3%. This study propose combination of the top-down and bottom-up methods to forecast the daily maximum demand of Malaysian large steel mills and the annual maximum demand contributed by these steel mills. The top-down approach uses regression analysis to forecast the annual electricity consumption of these large steel mills, based on its relationship with annual steel production and GDP. The projected annual electricity consumption from regression analysis was then integrated into the bottom-up model using MAED_EL to construct the hourly load curves. From the hourly load curves, the daily and annual maximum demands of the steel mills are determined. This model has the ability to forecast accurately the daily maximum of the large steel mills, with MAPE of less than 3%. The proposed method however, is purely based on the assumption that the future trend of daily consumption follows the base year. Although this is a slight drawback, nevertheless the proposed method has provided the utility with a better means to forecast steel millsââ¬â¢ load, despite the unavailability of daily production data which is vital in forecasting. The outcome of this study will benefit the utility in ensuring reliable and economic operation of the national grid, and is also useful for analysis pertaining to development of future optimal generation and transmission expansion plans. Findings of this study also give a valuable contribution to the utility in determining load management strategies and designing of tariff structures. A possible approach to improve the forecast performance is by combining the model with a time series method such as ARIMA. This will enable the model to take into account the most recent behaviour of steel mills load, and thus increase the accuracy of the forecast. The best approach however, would still be the one that is able to take into account the daily production data of the steel mills. With the availability of this particular data, many other complex and more effective methods can be explored such as Artificial Neural Network (ANN) and fuzzy linear regression. These methods will have the ability to capture the factors that highly influence steel mills daily load such as daily production plan and maintenance schedule, and hence improve the accuracy of the forecast. (S. Aman et.al, 2011 ) Long term energy consumption forecasting using genetic programming Managing electrical energy supply is a complex task. The most important part of electric utility resource planning is forecasting of the future load demand in the regional or national service area. This is usually achieved by constructing models on relative information, such as climate and previous load demand data. In this paper, a genetic programming approach is proposed to forecast long term electrical power consumption in the area covered by a utility situated in the southeast of Turkey. The empirical results demonstrate successful load forecast with a low error rate. In this paper, a genetic programming approach on the forecasting of long term electrical power consumption of a moderate city in Turkey was presented. It uses the genetic programming method to forecast future usage through symbolic regression using annual data of the previous years. In conventional regression, one has to decide on the approximation function (can be an n-degree polynomial, non-polynomial, or a combination of both) and try to find the coefficients of this selected function. Constructing an approximation function can be a difficult task. There is another form of regression called ââ¬Å"symbolic regressionâ⬠. In the symbolic regression problem, the aim is to search a symbolic representation of a model, instead of only searching for coefficients of a predefined model. Genetic programming (GP) method introduced by Koza can be used for the symbolic regression problem. GP searches for the model and coefficients of the model at the same time. In this study, power consumption data is processed with both conventional analysis and genetic programming techniques. Long term power consumption forecasting can provide important information for power distribution centers. Power consumption in this city is rapidly growing; therefore accurate forecasts can help authorities to make reliable plans. In this work, a genetic programming based forecasting method is presented. Two other curve fitting methods are also presented for comparison with this technique. Data used in all three models are not preprocessed. Genetic programming technique is used to form a model and evaluate the parameters for the model. The goodness of the fit produced by the genetic programming method is evaluated using sum of squared errors (SSE) method, which is better than the other two methods of regression. It was proved that the genetic programming can be used for electric utility resource planning and forecasting of the future load demand in the regional or national service area effectively. (K. Karabulot et. al, 2008) Electricity consumption forecasting in Italy using linear regression models The influence of economic and demographic variables on the annual electricity consumption in Italy has been investigated with the intention to develop a long-term consumption forecasting model. The time period considered for the historical data is from 1970 to 2007. Different regression models were developed, using historical electricity consumption, gross domestic product (GDP), gross domestic product per capita (GDP per capita) and population. A first part of the paper considers the estimation of GDP, price and GDP per capita elasticities of domestic and non-domestic electricity consumption. The domestic and non-domestic short run price elasticities are found to be both approximately equal to 0.06, while long run elasticities are equal to 0.24 and 0.09, respectively. On the contrary, the elasticities of GDP and GDP per capita present higher values. In the second part of the paper, different regression model s, based on co-integrated or stationary data, are presented. Different statistical tests are employed to check the validity of the proposed models. A comparison with national forecasts, based on complex econometric models, such as Markal-Time, was performed, showing that the developed regressions are congruent with the official projections, with deviations of 1% for the best case and 11% for the worst. These deviations are to be considered acceptable in relation to the time span taken into account. This paper aims to estimate GDP, price and GDP per capita elasticities of domestic and non-domestic electricity consumption in Italy. Also this paper wants to forecast the future growth of these consumptions using different regression models and compare our results with other available projections. The elasticity analysis showed that the price elasticity of domestic and non-domestic consumption is quite limited, confirming some results presented in previous studies. Through the findings, conclusions have been acquired. First, there is no need to consider electricity price as explaining variable in forecasting models for Italian electricity consumption. Second, pricing policies cannot be used to promote the efficient use of electricity in Italy. The estimation of GDP and GDP per capita elasticities showed higher values with respect to price elasticities, demonstrating that the consumption response to GDP and GDP per capita changes is relevant. Therefore, there is the need to assure an appropriate level of electricity supply to sustain the economic growth in Italy. According to the second target of the paper, different long-term forecasting models were developed and they substantially lead to similar results. Therefore, in the next years, an increase in the total electricity consumption, driven by both domestic and nondomestic consumptions, should be expected in Italy with an average rate equal to about 2% per year. Assuming that the data reported represent the reference benchmark, it can guarantee the most accurate projections for total, domestic and non-domestic electricity consumptions respectively, because they fit the data. It is believed that the elasticities, forecasts and comments presented in this paper would be helpful to energy planners and policy makers to build future scenarios about the Italian electricity consumption. (V. Bianco et. al., 2009) Forecasting electricity consumption in New Zealand using economic and demographic variables The inï ¬âuence of selected economic and demographic variables on the annual electricity consumption in New Zealand has been investigated. The study uses gross domestic product, average price of electricity and population of New Zealand during the period 1965ââ¬â1999. Models are developed using multiple linear regression analysis. It was found that the electricity consumption correlated effectively with all variables. Forecasts made using these models were compared with some available national forecasts. The forecasts are also compared with the forecasts of the previously developed Logistic model. Electricity consumption forecasting models based on economic factors for Domestic and NonDomestic sectors and Total consumption for New Zealand using multiple linear regression have been proposed. The models performed effectively in the statistical tests conducted, implying their signiï ¬ cance in forecasting electricity consumption using the explaining variables considered. Comparisons of these models have been made with the national forecasts available in New Zealand. The comparison revealed that the forecasts made by the regression models are very comparable with the national forecasts. The accuracy of the forecasts made by these models depends strongly on the accuracy of forecasts made for the explaining variables. In this paper, simple regression had been used to model these variables. (Z. Mohamed & Pat Bodger, 2003) Modeling and Forecasting Electricity Demand in the Philippines The Philippine government has deregulated electricity generation markets to encourage private investors and actively courted independent power producers (IPPs). This has been done to promote efficiency and reduce government financial debt obligations. Until the mid-1980s, the power sector in the Philippines was mostly state-owned through the National Power Corporation (NPC). After the debt crisis in the early 1980s, the Philippinesââ¬â¢ government tightened fiscal policy, and capital expenditure for additional electricity capacity was significantly reduced. This led to a slowdown in the electricity generating facilities. At the same time, electricity demand continued to increase. This resulted in tight electricity supply and demand conditions by the middle of the 1980s. There continue to be periods of generating capacity constraints. This may be the result of difficulties in forecasting electricity consumption. The residential and industrial electricity demand in the Philippines is modeled. The analysis follows Johansenââ¬â¢s vector error correction approach to estimate the price and income elasticity in both long and short run. The results indicate a long run cointegrating relationship is found among residential electricity consumption, income, and the stock of electric appliances. In the industrial sector there appears to be a long-run relationship holds for industrial electricity consumption and GDP. The lack of significant price responses appears to be the result of government development policies. The estimated models are used in forecasting total electricity consumption suggest that the governmentââ¬â¢s official forecast for electricity demand would be on the upper bound of the forecast range. (K. Ishi & F. Joutz, 2009) Methodology 1. Collect data of the Philippinesââ¬â¢ monthly electricity consumption from the year 1999 to 2011 in National Statistics Coordination Board to be used for constructing a time-series model for the electricity consumption. 2. Using the formulated model, forecast the Philippinesââ¬â¢ electricity consumption for the next three years. 3. Through the acquired forecasted consumption, evaluate the performance of the model.

Gender Criticism based on Feminism and Masculinism in the Book ââ¬ÅSkinââ¬Â Essay
The book entitled, ââ¬Å"Skinâ⬠is written by Ted Dekker and is a fiction novel about a killer who took as captives five people who each had stories to tell and had things about their past to confront. They were brought together by such deadly circumstances and despite their individual differences and suspicions drawn against one another, they had to work together somehow against a common enemy, their captor. ââ¬Å"Skinâ⬠covers issues of feminism and masculinism in the details about how the captured characters ââ¬â namely, Wendy, Colt, Jerry, Nicole and Carey ââ¬â were victimized by the killer, Red. For Wendy, it all started one rainy night when she was driving herself to the place where her estranged mother was. The horror of all that they have gone through, all five of them, turned out to be something none of them was ever prepared for. Thesis The novel ââ¬Å"Skinâ⬠relates a story that supports the thesis that the gender-defined roles of the characters therein damaged both sides. The story also presented the question of what true beauty is, both masculine and feminine beauty. Beauty is explored both as an external quality and as something that is more than what meets the eye ââ¬â in men and in women. It turns out that beauty can be perceived by people as gender-defined. Beauty in men, thus, can be judged by parameters that are supposed to apply to men, and then beauty in women can be judged by altogether different parameters that, in turn, are supposed to apply to women. Feminism in the Story Wendy is an escapist from a cult where men reigned as the superior sex. In fact, even decisions pertaining to her life ââ¬â who she was to wed eventually, who she could date and kiss ââ¬â were made by the acknowledged head of their tribe, a man much older that her who was even supposed to be her future husband. Her mom was in the cult, too. As a member of it, she submitted to such leader and went to wherever the group went, never deciding for herself where and how she wanted to live her life. Through it all, she allowed the cult leader to make decisions that she should have made for herself and her daughter, Wendy. Wendy has become a prime feminist since her escape from the group whose members made up her world. She then became totally free ââ¬â free to make choices for herself, free to make decisions concerning herself, her life and her personal interests. She has been equipped with good education and having been a scholar who made it through college by herself ââ¬â with no help from parents, whose support usually comes in the form of financial resources to enable their children get through college as a way to have much better chances for a bright future. During her traumatic childhood experiences in the cult where the male leader was practically the ruler of all, Wendy had known what it meant to be eyed or even ââ¬Å"reservedâ⬠for an older man. In the story, there was the pre-arranged marriage that Wendy had no choice but to succumb to when the time for it would come. For this reason, Wendy was even punished at one time for having kissed a guy. Through it all, Wendy came to have this fear of men. It was the same fear that went in the way of her having a serious relationship with a guy even when she was already a young woman. Thus, during years since her escape, Wendy had only female friends. Given the life she lived and the role of men in her life, Wendy has grown to be an independent woman who definitely did not need a man to make life easier for her. In contrast, Nicole had her brother, Cary, to adore her, to take care of her and to protect her. She grew up depending on the love and security that her older brother represented. Nicole represents the very image that present day feminists want to totally disassociate from women in general. Sheââ¬â¢s a victim of men who, like her brother, have to be needed by the women in their lives as the only way they would feel strong, masculine and happy. In such a trap, the likes of Nicole have been raised to believe that women are weak and are in constant need of the protection and support that only men can provide. For an independent woman like Wendy, it was indeed a novelty to watch Carey carry his younger sister all the way and to see for herself how much Carey loves his younger sister, Nicole. And Nicole, loved him, too. He was her older brother who has always been her source of love and protection. The same love and protection, though, can serve to curtail Nicoleââ¬â¢s potentials as a person ââ¬â a free thinker, a decision-maker and the master of her fate. Thus, the protective love of men ââ¬â in this case, Nicoleââ¬â¢s older brother ââ¬â can be likened to a trap that can prevent women from going out into the world, making mistakes and learning in the process, and living their lives to the fullest. Curtailed freedom was one thing Wendy and Nicole had in common, but Wendy had chosen to break out of her prison cell and fly away toward freedom and self-realization. Men, as oppressors, can clip the wings of the women in their lives either intentionally or not, either lovingly or not ââ¬â the manner, though, does not change the meaning of what is going on. Masculinism in the Story Coltââ¬â¢s masculinity would seem readily obvious in the light of his being a policeman. His marked skill as a gunman would serve to give his masculinity an added boost. After all, his being an adept shooter can easily be surmised to mean his being a good protector of people under his wings. As a great gunman, then, Colt has won the respect and admiration of his fellow cops in the police department, both male and female. And also as a great gunman, Colt would seem the kind of man who has little or nothing to fear. No one would guess, therefore, that for all his seemingly apparent masculinity, Colt has fears and has doubts of his capabilities and qualities as a man. In fact, the story says that having a woman around or being with one is enough to break Coltââ¬â¢s cool demeanor and to reduce him into a bundle of nerves. He therefore has neven been close to a woman. His life has been lived and has revolved pretty much around male friends. The story has mentioned Coltââ¬â¢s mom who has been murdered but was believed to have committed suicide ââ¬â she might easily have been the only woman in his life. Oneââ¬â¢s childhood always leaves its imprints on the person. Events during Coltââ¬â¢s childhood have caused him to have insecurities and doubts about himself. These self-doubts leave no sign in the policeman that Colt has become. Such doubts and insecurities have stayed within him but have been buried way under Coltââ¬â¢s demeanor. In a way, Colt has been victimized by the way ladies ridicule guys they are not interested in, more so when ladies spurn those suitors whom they do not at all find attractive. Being rejected by a girl can have such an adverse impact on a guyââ¬â¢s confidence. Some guys even find it hard to recover their self-esteem after having been rejected by the ladies they loved. While Colt avoided women as characters he was not ready to have in his life, Cary was the type of guy who was instinctively protective of women he loved, like his sister, Nicole. Cary has grown up believing that the male sex is the stronger sex and that the females are therefore to be taken care of and sheltered. While adhering to this belief, being in helpless situations would kill the likes of Cary in their insistence that they be the protectors of the women they love. Thus, in the story, it tore Cary apart to watch his younger sister in pain and so helpless. It likewise broke his heart that he could not do what had to be done to keep them all safe from harm. Thus, independent women like Wendy would be a novelty to Colt, whose perception of women would be more of the clinging and needy sort. In the same way, frail and fragile women like Nicole would disarm Coltââ¬â¢s defense and lead him to overcome his fear of women, who in the person of Nicole can seem to be such weak, dependent and powerless creatures in need of somebody like himself. The story is adroitly set with twists that all served to help the characters eventually face their fears and find themselves. Works Cited Dekker, Ted. Skin. Tennessee: Thomas Nelson, Inc. 2007.
