In this paper the capacity distributions corresponding to several well-known aggregate production functions (Cobb-Douglas, CES and VES) are derived. It is shown that these distributions can be transformed to beta-distributions in a straightforward way.  相似文献

Bunk beds have long been recognised as a potential source of injury to children. This study was undertaken to establish an evidence base for a proposed injury reduction program and to determine whether or not there is a case for a mandatory safety standard. Recent literature on bunk bed safety was reviewed to provide an overview of the injury issues involved. Major sources of relevant Australian and international data were identified and the available data summarised. An in-depth analysis of Victorian data was undertaken to identify the nature and severity of injuries sustained and any patterns or trends, including age profiles. It is estimated that, in Australia, in the under fifteen age-group, there are at least 2,100 bunk bed-related injuries treated annually by hospital emergency departments. This represents a rate of about 50 injuries per 100,000 age-specific population. The majority of these injuries (86%) occur in children under the age of 10 years with injuries peaking in the 5-9 year age-group. The main cause of non-fatal injury is falls from the top bunk resulting in a fracture (33%), mainly to the upper extremity (75%). There have been at least two deaths from asphyxia in Australia in the past 10 years, due to entrapment in the bunk structure. It is clear from the current evidence that bunk bed injuries are a significant problem in Australia and represent a life-threatening hazard to young children in particular. The existing voluntary Australian/New Zealand Standard adequately addresses the safety issues raised by the examination of the literature and the analysis of the injury data. It is also clear that, in Australia, voluntary standards and the market place have been ineffective in achieving compliance. It is therefore recommended that the Australian Standard be made mandatory in an effort to significantly improve the safety of bunk beds in Australia.  相似文献

We build on limited research concerning the mediation processes associated with the relationship between ethical culture and employee outcomes. A multidimensional measure of ethical culture was examined for its relationship to overall Person-Organization (P–O) fit and employee response, using a sample of 436 employees from social economy and commercial banks in Spain. In line with previous research involving unidimensional measures, ethical culture was found to relate positively to employee job satisfaction, affective commitment, and intention to stay. New to the literature, ethical culture was also found to be associated positively with employee willingness to recommend the organization to others. These effects were observed even when perceptions of P–O fit were controlled. Importantly, ethical culture was also positively related to overall P–O fit, which in turn, partially mediated the relationship between ethical culture and employee outcomes. Our findings add to studies that focus on the importance of the degree of ethical congruence between the individual employee and the organization. They suggest that ethical culture, with its expected impact on virtuousness and emotional well-being, will positively influence outcomes independently of the degree to which there is a match between employee and organizational values.  相似文献

Substantial growth in inorganic fertilizer use is a prerequisite for sustained agricultural growth in sub-Saharan Africa. Increased fertilizer use can lead to modest but immediate and important increases in yields, while the profitability of other technologies will be stifled without adequate plant nutrients. Average fertilizer application rates in sub-Saharan Africa need to increase from 10 kg/ha to 50 kg/ha within 10 years to prevent mining of soil nutrients. That implies an 18% annual growth rate. This is substantially higher than trends in the region, but within a reasonable range of historically observed levels from other parts of the world. While over-use of fertilizers can create environmental problems, this is not a widespread problem in sub-Saharan Africa, and should not become one as a result of applying 50 kg/ha of inorganic fertilizers. Rather, near-term environmental concerns in agriculture in sub-Saharan Africa will stem from the lack of intensification. Farmer demand for fertilizers and the physical capacity to make fertilizers available are the two key issues that determine whether a 50-kg/ha goal will be attained. However, demand-side incentives cannot be separated from fertilizer supply possibilities. Several studies document that the simple physical availability of fertilizers to farmers, in the appropriate quantity, packages and at the appropriate time of year, remains a main constraint on increased fertilizer use in sub-Saharan Africa.  相似文献

As early as the 1970s, European Union (EU) member countries implemented rules to coordinate insurance markets and regulation. However, with the more recent movement toward a general single EU market, financial services regulation has taken on new meaning and priority. Solvency I regulations went into effect for member nations by January 2004. The creation of risk-based capital standards, the main focus of Solvency II, now appears likely sometime after 2007. The purpose of the discussion presented here is to outline the specifics of Solvency II as they currently stand and suggest important areas of future research.  相似文献

This study investigated the impact of investments in human capital on the economic well-being of black and white women immediately following marital disruption. It also explored the extent to which the observed differences in income between the two groups were due to differences in the levels of qualities (endowments) or differences in the impact of these qualities (discrimination). The average differences in endowments explained almost two-thirds of the income gap between black and white women. Most of this explanatory power was due to differences in educational attainment, work experience, and region.  相似文献
