The first objective of this article is to clarify which model best captures the structure and trend of the influence of social origin on children's education. The second objective is to analyse how general conclusions on historical trends in educational reproduction change if we add mother's status background to the model. Six contrasting hypotheses are derived fromthe body of literature dealing with models on families' socioeconomic status. All hypotheses are translated into empirical models and their explained variance is compared. A pooled data set is used that contains data from the Netherlands, West Germany, and the USA. The Modified Dominance Model, that distinguishes the influence of the highest from thelowest status parent, has the best model fit. Regarding the second objective we see that adding the mother's influence to that of the father's does not change general conclusions on trends in educational reproduction. Over time the influence of both parents decreases continuously. However, the influence of the mother's education and occupational status on children's educational attainment is substantive. 相似文献

Kamstra et al. [Kamstra, M.J., Kramer, L.A., Levi, M.D., 2000. Losing sleep at the market: the daylight saving anomaly. The American Economic Review 90, 1005–1011] argue that the mean weekend return following the changes in daylight saving time is less than the mean weekend return throughout the rest of the year. Opposing studies, such as Pinegar [Pinegar, J.M., 2002. Losing sleep at the market: comment. The American Economic Review 92, 1251–1256), reason that the observed results depend upon methodology. We extend the ongoing discussions by providing further evidence for equity markets and bond markets in Germany and across Europe. We further demonstrate that the daylight saving effect does not serve as a potential rationale for the weekend effect. 相似文献

The fundamental character of a punishment is the subject of this paper. Based on the assumed function of a punishment (deterrent), a punishment has to be perceived and experienced to be an adverse result by the punished and the public. The first factor in particular means that the courts have to have flexibility to sentence a person to such a punishment that is experienced as such. The legal question becomes how this customization of a punishment is acceptable from an equality standpoint. In the field of environmental protection, the administrative process poses serious problems. There may be administrative proceedings that result in substantial economic losses for individuals and groups alike.
Jürgen S. Poesche was born in Edmonton (Alberta, Canada), lived in Europe and North America and graduated from the Helsinki University of Technology, University of Helsinki, Swedish School of Economics and Business Administration and Tampere University of Technology. Areas of interest include chemical and mechanical pulping, environmental protection (EIA, environmental ethics, environmental law), and capital investment decision-making. He has published in, e.g., Wochenblatt für Papierfabrikation, Finnish Journal of Business Economics, Ympäristojuridiikka (Environmental Law), and in the publication series of the Helsinki University of Technology and the Tampere University of Technology. Presently, he is working for a major Canadian forest products company. 相似文献
