The Turkish electrical system has been studied, particularly for the near term investment programme. The objective of the study was to determine the most likely investment alternatives for the next ten-year period, from a cost effectiveness point of view. A dynamic linear programming model was used in representing the national energy system, with special emphasis on the electricity sector. Hydro, coal, nuclear and oil-fired power plants as well as their interconnection investments were modelled. A 27-year planning horizon was defined. The scenario approach was utilized in establishing the effects of different factors, such as foreign currency requirements of projects, nuclear plant costs and nuclear fuel costs, demand growth rates for electricity as well as other fuels, availability of foreign currency and skilled manpower, and the development rates of coal mines, coal power plants and nuclear power plants. After analyzing the results of 24 different scenarios, robust plans for developing the power system are suggested. Other investments that are subject to the realization of certain conditions are also indicated. 相似文献

It is shown that for independent (but not necessarily identically distributed) random variables with distributions symmetric about the respective medians (means), the expected value of the sample range is a minimum when these means are all equal. 相似文献

In this study, the Power Sharing in Couple Relationships Scale (PSCRS) was developed to measure the distribution of power as experienced by individuals in heterosexual marriages or cohabiting relationships. Three sets of participants partook in the study: 27 individuals were in the pilot group; 400 individuals (female = 200, male = 200) were in the exploratory factor analysis group and 242 persons (female = 139, male = 103) were in the confirmatory factor analysis group. Factor analyses resulted in a structure consisting of 30 items and five dimensions, namely, friendship, power over, reactivity to relational stress, openness to influence, and making a relational claim. Results showed evidence for satisfactory psychometric properties. 相似文献

Microcredit has been recognized as one of the most efficient tools for alleviating poverty by the United Nations considering its significant contribution in terms of job creation and revenue generation for governments. Microcredit programs can change the lives of people and revitalize communities in the world’s poorest as well as the richest countries. This study looks at 350 entrepreneurs who joined the scheme of various microcredit programs in Penang, Malaysia. In this study, findings have been obtained that show that microcredit loans have successfully increased entrepreneur income, have positive impacts on business, and fulfill basic needs of entrepreneurs. 相似文献

This profile gives an overview of the student protests and university occupations of the winter of 2010–2011 against the Conservative–Liberal Democrat coalition government's higher education bill. In particular, the lifting of the cap on annual higher education tuition fees to £9000 pa was widely perceived by students (and lecturers) as unjust, unfair and a very real barrier to higher education. In order to understand the political dynamics of these student mobilisations, I argue both that we need to consider the network structure that exists on university campuses and how it facilitates political mobilisations, and to see the protests as a moral economy directed against a new toll on higher education. 相似文献

The present paper analyzes the role of stock market, more specifically real stock prices and stock market uncertainty/volatility, on aggregate investment behavior for an emerging market, Malaysia. Employing the autoregressive distributed lags approach to cointegration test, the paper establishes a long run equilibrium that ties the aggregate investment to its determinants—real income, real stock prices, real lending rate and stock market volatility. In the long run, we document a positive relation between aggregate investment and real stock prices and a negative relation between aggregate investment and stock market volatility. These results are further supported by our analyses of their dynamic interactions based on Granger causality and impulse-response functions. Based on the results, the real stock market prices, which has yet reached the level recorded prior to the crisis, may have explained the low investment in Malaysia after the Asian crisis. Moreover, the stock market volatility can also post a threat to the investment performance. 相似文献

Although mosques worldwide serve the same spiritual purposes, they are significantly different in structure from one area to another within and among localities, countries and continents of the world. Muslims used whatever was available to them in their environment and their limited experience in building mosques resulted in structural differences in mosques until the age of globalisation, when some world-class mosque structures were popularised among Muslims. This paper is an attempt to produce a historical survey of the architectural designs of mosques in Ilorin in the nineteenth and twentieth centuries. Through exploratory research, the paper gives a thematic history of Ilorin mosques’ architecture that started as a simple structure in the nineteenth century reflecting the immediate cultural setting, to become edifices in the twentieth century reflecting outside cultural influences, for the purpose of meeting the spiritual, social, physical and psychological needs of Muslims. 相似文献

Individuals’ occupational and educational attainment is influenced by their ethnicity, religion and colour in the UK and elsewhere. In this paper, we analyse the impact of ethnicity, religion and colour along with residential segregation1 and socio-economic deprivation on returns to education for men in England and Wales. We analyse the 2001 UK census data by employing multi-level logistic regression models. It is found that non-White groups including Christian Black-African, UK born Sikh-Indians and South Asian Muslims are found to suffer an ethnic penalty compared to Christian White-British. While there is evidence to suggest that Muslim men may experience a greater penalty compared to some non-Whites other non-Muslim groups too face ethno-religious penalties, sometimes even more severely such as in the case of Christian Black-Africans. Socio-economic difficulties faced by ethnic minorities are also linked to spatial segregation only when associated with high levels of area deprivation. This suggests that what matters may not be segregation per se, but whether or not it is associated with deprivation. 相似文献

In the usual credibility model, observations are made of a risk or group of risks selected from a population, and claims are assumed to be independent among different risks. However, there are some problems in practical applications and this assumption may be violated in some situations. Some credibility models allow for one source of claim dependence only, that is, across time for an individual insured risk or a group of homogeneous insured risks. Some other credibility models have been developed on a two-level common effects model that allows for two possible sources of dependence, namely, across time for the same individual risk and between risks. In this paper, we argue for the notion of modeling claim dependence on a three-level common effects model that allows for three possible sources of dependence, namely, across portfolios, across individuals and simultaneously across time within individuals. We also obtain the corresponding credibility premiums hierarchically using the projection method. Then we derive the general hierarchical structure or multi-level credibility premiums for the models with h-level of common effects. 相似文献
