I analyse a variety of evidence for Japan and, where available, for the United States on bequest practices, the importance and nature of bequest motives, bequest division, the willingness of individuals to help others, etc., in order to shed light on which model of household behaviour applies in the two countries. My results suggest that the selfish lifecycle model is the dominant model of household behaviour in both countries but that it is far more applicable in Japan; that the dynasty model is also more applicable in Japan but is not of dominant importance even there; and, conversely, that the altruism model is far more applicable in the USA.

The structure and financing of science and technology activities are undergoing a slow, but profound, change. This change can be briefly characterized as a shift from relying and supporting public science to a stronger emphasis on “market-based” incentives for science and technology. In this paper we analyze this shift in a historical perspective, discussing both the theoretical explanations and the empirical trends of the ongoing change. While we do not claim to provide a comprehensive and exhaustive identification of the causes of this shift, we argue that it is largely driven by the perception of a shift of the U.S. policy towards market-based, rather than publicly supported, incentives for science and technology. This, in turn—given the strong economic performance of the United States over the 1990s—has influenced policies in most OECD countries, especially in Europe.We conclude by analyzing the evolution of research in U.S. higher education and find two major trends: an increasing diversity in the number of institutions of different types other than universities and a steady and continuous public funding of the leading U.S. universities. This has allowed the construction of an infrastructure now used largely by the private sector, but it also noted that the United States has not compromised public support for core areas or in those fields in which there is a clear perception that market incentives are not sufficient for meeting the strategic targets of the U.S. policy. The implication is that there is a considerable policy diversity in the U.S. practice and that all aspects of this diversity should be considered when using the United States as a reference.  相似文献

Japan's wage setting system has undergone considerable decentralisation since 1995. An overview of recent changes, framed by comparative analysis, suggests that rapid change has occurred because of the informal institutionalisation of industrial relations practices, which reflects in turn the strong enterprise consciousness of workers and unions.  相似文献

The exchange between Brenner and Wood on the Low Countries in the early modern period raises a number of theoretical and historical issues relating to the conditions for the emergence of capitalist social-property relations and their unique historical laws of motion. This contribution focuses on three issues raised in the Brenner-Wood exchange: the conditions under which rural house-hold producers become subject to 'market coercion', the potential for ecological crisis to restructure agricultural production, and the relative role of foreign trade and the transformation of domestic, rural class relations to capitalist industrialization.  相似文献

A growing awareness of workplace hazards and identification of airborne contaminants, coupled with a changing safety and health regulatory environment, created an unexpected demand for new and innovative respirators in the early 1980s. 3M's Occupational Health and Environmental Safety Division broke new ground by taking the team concept further than ever before in the company. The division's Action Teams successfully designed, built and introduced products in less than half the time it would have taken previously. Robert Hershock, Charles Cowman and Douglas Peters describe how 3M learned important lessons about team selection, training, performance and motivation, the importance of project sponsors, and the role of middle management.  相似文献

Abstract.  We use tax‐based longitudinal microdata for 1982–99 to (i) examine how earnings distributions have shifted, (ii) identify changes in earnings mobility patterns, and (iii) replicate and update Beaudry and Green's cohort analysis of age‐earnings profiles. We find: (i) increased polarization of men's earnings and marked decline in real earnings of workers aged 20–4; (ii) general decline in men's earnings mobility, while women's mobility has increased for young and prime‐age workers; and (iii) upward drift in earnings profiles of 1960s–1970s entry cohorts and downward shifts for 1980s–1990s cohorts (largely confirming Beaudry and Green's findings), but suggestive of steepening profiles for the 1990s cohorts.

In order to aid Singaporean SMEs identify and select emerging technologies for business benefit, a modified process of the Cambridge T-Plan methodology has been introduced and applied to a pilot sample of 30 companies in a variety of manufacturing sectors. This fast and simple process takes the company through five key steps to enable them to create their first Operation and Technology Roadmap (OTR). The paper explains the background to the approach and focuses on the initial benefits identified by a survey of the pilot companies.  相似文献

Capacity planning and resource allocation are crucial to the cost-effective delivery of health care services. In this paper, we present an analytic approach based on a modified version of the Holt-Winters multiplicative seasonality forecasting model to determine the frequency distribution associated with a hospital care unit's census. This paper is a follow-up to the census frequency distribution simulation model described in Lapierre et al. (Socio Econ. Plan. Sci. 33 (1999) 25). We demonstrate that our model can provide census frequency distributions equivalent to the simulation model of Lapierre et al. [1], but without the computational effort common to simulation models.  相似文献

The emerging concern about software piracy and illegal or unauthorized use of information technology and software has been evident in the media and open literature for the last few years. In the course of conducting their academic assignments, the authors began to compare observations from classroom experiences related to ethics in the use of software and information technology and systems. Qualitatively and anecdotally, it appeared that many if not most, students had misconceptions about what represented ethical and unethical behaviors in these realms. Clearly, one can argue that if college students are uncertain about what constitutes appropriate and inappropriate behavior then this uncertainty will be carried forward into their workplaces upon graduation. Furthermore, if their workplaces don't provide ethics training as a component of a new employee orientation program, one can project a potential for unintentional violations and infringements of copyrights and law in the field. This study was conducted among graduate and undergraduate students to gain insight into their attitudes, perceptions and understanding of some of the relevant ethics issues. A questionnaire of 11 statements was employed that described ubiquitous but most likely unethical (or surely dubious) behaviors in the prevailing business and academic environments. Each respondent was asked to evaluate each statement twice (once for “self” and once for “colleague”) on a five-option highly ethical (5) to neutral (3) to highly unethical (1) scale. The statements were worded such that lower instrument score was associated with higher ethical responses. The questionnaire's two-part structure was designed to solicit honest answers. The encouraging learning from this study was that the overall sample and its various sub-samples did not consider any of the eleven behaviors to be “ethical” or “highly ethical.” It was also encouraging to note that the overall sample and all sub-samples considered “highly unethical” those behaviors associated with personal privacy or property or outright theft. This indicated that moral judgment and probity prevail. The discouraging learning was that behaviors associated with the use of enterprise property were viewed as “neutral” i.e., neither “ethical” nor “unethical.” These findings suggested confusion and lack of clarity and definition around workplace deportment as it regards ethics in software and information technology use. The current study suggests that additional research needs to be conducted to define and clarify the issues, which in turn can form the basis for programs to rectify or at least ameliorate the situation.  相似文献
