Objective. Focusing on housework activities, we hypothesize that the degree of specialization is influenced by economic notions of efficiency, as well as by time constraints and egalitarian values. Methods. Employing time‐use data on U.S. and Danish couples, we construct a composite index measure of intra‐household specialization. We analyze the comparability of reported time use and our specialization index using different types of data, and then model specialization using a multivariate two‐limit Tobit. Results. We find evidence that Danish households specialize less than U.S. households and that children, particularly preschool‐aged children, are associated with significantly increased specialization in the United States but not in Denmark. Conclusions. We postulate that the more egalitarian social structure in Scandinavia is a driving force behind the lower rate of specialization observed in Denmark. Further, we believe the subsidized child‐care services provided by the Danish welfare system reduce the impact children have on specialization in ordinary housework tasks.  相似文献

The author was involved in the 1973–1974 acquisition chase in the U.K. and in the Pacific Basin while working for a British company noted for its acquisitiveness. A mystique has grown up around those people who buy companies and individuals who surround themselves with secrecy and charisma are hiding one essential fact; appraising target companies is not very different from appraising any other direct investment. In fact the task lends itself to a combination of simple economics and plenty of common sense.  相似文献

We describe the analysis of some matched-pair binary data arising from a study designed to investigate whether cellular-telephone use is associated with motor-vehicle collisions. Conditional and random effects approaches to the problem are derived and compared. Driving intermittency is a potential confounder whose effect is assessed by strategic choices of the control period and by application of the bootstrap. The marked discrepancy between the conditional and random approaches merits further study.  相似文献

Plant investment decisions are frequently crowded with folk-lore, even though basic economics may provide a ready guide to optimum capacity.Increasing emphasis on corporate accountability is producing the need to accept a more numerate approach to business decision taking while the overall scope for off-the-cuff decisions is rapidly diminishing. One important area of business decision taking concerns plant investment and in this paper an approximation routine is outlined for determining by economic analysis the optimum plant size for new ventures. Attention is also drawn to the importance of organization structure for investment planning.  相似文献

THE ELDERLY VICTIM OF HOMICIDE:   总被引:1,自引:0,他引:1  
This study attempts to resolve some of the disparity between lifestyle/routine activities theory and empirical findings concerning the elderly victim of homicide. Analysis of Canadian data leads to the conclusion that the elderly are disproportionately victims of theft-based homicide, a finding not consistent with the routine activity approach. A reformulation of the theory resolves the theory/data gap.  相似文献

Children’s online experience, especially the risks to which they might be exposed, is an increasingly important policy and research concern. This article reports an analysis of the amount, nature and range of empirical research concerning children’s online experiences across 18 European countries. Research teams in each country have collaborated, as part of the ‘EU Kids Online’ network, to identify, code and compare studies. In all, 235 studies were identified and coded in a publicly accessible data repository. All countries had some available evidence regarding children’s online risky experiences, with strengths mainly in relation to research into access and use; several countries were found to have a richer evidence base encompassing research into online learning, literacy, participation, parental mediation and so forth. Regarding risks, more research focused on potentially harmful content than on risky forms of contact. Key research gaps included research on younger children, into mobile online platforms, and into certain types of online risk. The article concludes by observing the challenges facing researchers in this field, including the time‐sensitivity of research that quickly dates, the difficulty of tailoring research to meet the needs of a demanding policy agenda, the complexity of designing projects that recognise the contextual and contingent factors that mediate children’s online activities, and the ethical considerations that apply when asking children about private, transgressive or upsetting experiences.  相似文献
