This paper provides an analysis of major management challenges and tensions within the European nuclear power industry in the context of safety. The results show that human resource management, organisational climate and culture, and public confidence and trust are the three most challenging areas for nuclear managers across Europe. Managerial tensions typically relate to the setting of priorities and maintaining focus, and to the need to find a balance between diverging demands and expectations, such as perceived conflicts between economy- and safety-related objectives. Overall, the results suggest that nuclear managers need and use complex models for structuring their realities and that the safety of a nuclear power plant cannot be managed independently of the other goals of the plant organisation.  相似文献

Several European Union countries have recently implemented or are envisaging fiscal operations which improve budgetary figures but have no structural impact on government finances. We evaluate some of these measures using a balance sheet approach. In particular, we examine the degree to which reductions in government debt in EU countries has been accompanied by a decumulation of government assets. In the runup to Maastricht we find a strong correlation between changes in government liabilities and government assets, and larger declines in government assets in countries starting from higher public debt levels.  相似文献

This paper looks at surplus extraction by network providers who control the medium of information transfer between application developers and consumers, and addresses the following questions: is net neutrality beneficial to society? and does providing network providers flexibility in pricing stunt innovation in the long run? To answer the first question, it looks at a market consisting of a monopoly network provider and two application providers with non-substitutable products, using a simple single period model. It shows that net neutrality is necessary to ensure maximal benefit to the society. To answer the second question, the paper shows that a monopoly network provider, if allowed complete flexibility in pricing, does not necessarily stunt innovation. Looking at a market that consists of one network provider and one application provider, and using a simple multi-period model, it shows that given maximum flexibility the network provider not only encourages innovation when the potential benefits are sufficiently high but also maximizes surplus. This paper takes the view that the topic of net neutrality is not only controversial but also complicated, and suggests that policy makers use a balanced approach based on sound analysis.  相似文献

In Southeast Asia, the issue of “social safety nets” (SSNs) has emerged more prominently since the financial crisis. Despite the increased interest in social safety nets, there is still considerable confusion among scholars and national and international organizations regarding the use and meaning of the term. This article considers the different definitions of the term—particularly as it was used during the Asian Financial Crisis—and to attempt to clarify its meaning and proper use.The safety net analogy is drawn from high-wire walkers who are protected by a safety net if they fall. The safety net prevents any walker who falls—unexpectedly or not—from hitting the floor and incurring catastrophic injuries. Following this line of reasoning, it is not surprising to learn that some organizations and scholars use the term SSN such that it encompasses private and public mechanisms that assist individuals in maintaining a minimum level of consumption.The term “social safety net” (SSN) began to be used by Bretton Woods’ institutions in connection with structural adjustment programs related to their lending programs. Developing countries introduced SSNs to mitigate the social impact of structural adjustment measures on specific low-income groups. They were initially formulated to serve three objectives: poverty alleviation, to make adjustment programs more politically acceptable, and institutional reform. During the Asian Financial Crisis, there was a great deal of confusion regarding the content and consequent identification of SSN programs.Public SSN programs can be classified into formal and informal safety nets. Formal and informal safety nets are, generally, distinguished by law enforcement: formal safety nets are those which legally guarantee individuals access to economic or social support whereas informal safety nets provide likelihood of support to individuals to assure them of attaining or remaining above the designated minimum standard of living but with no legal guarantee.Informal SSNs can be divided into private and public ones. Examples of private informal SSNs include transfers from family members, friends, neighbors and community members and institutions, including NGOs, while those of public informal SSNs refer to the support which individuals can hope for from the government, through programs which generate assets or employment, transfer income, or provide basic social services, as a means of helping affected individuals from falling below the designated minimum standard of living. The difference between formal and informal public SSNs is whether there exists a formal legal support of the assistance.The article has provided more discussion on the definitions of SSN used by the World Bank, ESCAP, ILO and TDRI.In conclusion, the authors note that the tremendous variation in the use of the term invites confusion and makes it virtually useless as a technical concept. The very nature of the metaphor invokes a vision of a large net that encompass a number of different types of programs. In many cases it is not even possible to list specific programs that are included, as the particular forms of these programs could, of course, vary with place, time and circumstances. Complicating things further, the term is sometimes used in a very narrow sense. Given the low probability that usage of the term will ever be standardized, economists and national/international organizations might be well served by avoiding the term completely and instead using its component parts.  相似文献

The surplus on a life insurance policy is defined, at any time during the term of the contract, as the difference between the second order retrospective reserve and the first order prospective reserve. General principles for redistribution of the systematic part of the surplus as bonus are formulated, and various special bonus schemes are discussed. Techniques for forecasting future bonuses are worked out in an extended model with stochastic experience basis. Numerical illustrations are provided.  相似文献
