This paper is concerned with one central question: the choice between theories, and the role played by data in that choice. It deals with the uses economists may make of data and the importance of understanding the institutional basis that gives rise to the data - an area in which labour economists have traditionally been particularly strong - and with the relevance of assumptions. It deals with the ultimate need to choose between competing theories (despite the role of conventionalism) on the basis of data rather than retreating into a comfortable 'methodological pluralism'. It considers the role of test replication, with reference to the practice in natural science (and its role there in checking scientific fraud) and concludes that, despite extensive technical problems of testing, economists have to accept a data check if the rhetoric of mathematical technicality is not to overwhelm the need to explain. Parallels are drawn with experience in physics (and the implications of the development of Chaos and Catastrophe for a naively predictionist view are noted), medicine and history (of which, it is argued, modern economists are far too neglectful). 相似文献

This study demonstrates that place—defined in this article as labor market area (LMA)— provides a useful context for examining how youth manage gendered situations. Places vary by conditions in which gender is more, less or differently salient, and a particular mix of factors accommodates different individual outcomes. This study utilizes multi–level modeling to examine influence of LMA characteristics on over–time educational measures for young women (Center for Human Resource Research 1994). Hierarchical models determine place–level effects on both average outcomes (within and between LMAs) and attainment processes. A major finding of this study is that aggregate place effects channel personal decisions and outcomes of young women. Young women's educational aspirations are dependent on gender– specific variables such as the number of women in college or the number of young women married in a local area. Attainment depends on the percentage of women in higher education and a local labor market's average age at first marriage. Further, what are assumed to be positive environmental effects (e.g., manufacturing dominance) are based on structural advantages for men and actually depress outcomes for women. Notably, the influence of place is independent of strong individual–level determinants, including social class. 相似文献

At present, our society and its social security system are not prepared to cope with the challenges resulting from the continuous increase of life expectancy. The traditional concept of disease has to be modified for serving the special needs of the elderly. The optimistic compression of disease theory is an intriguing model, but lacks prove by available data. The anti-aging boom diverts the focus from the social and financial burden that will be unevitably caused by long-term care in the future. If there will not be an — up to now unforeseeable — breakthrough in research, particularly dementia will have an enormous impact on social cost which is often underestimated. 相似文献

The evolution of society and economic pressure has provided the impetus for operating on a 24-hr basis in many industries. This has occurred with relatively little attention toward sleep deprivation and related problems facing shift workers and the organizations employing them. This paper first documents the move toward shift work and some sleep problems associated with it. We then describe sleep disorders that impact job performance. Next, we describe alternative schedules and give suggestions for shift work implementation. Finally, we offer some normative advice regarding the treatment of shift employees. 相似文献
