We investigate the argument that men who are raised by working mothers develop a preference that is favorable toward working women and, consequently, are more likely to have working wives. We test this hypothesis using the Japanese General Social Surveys 2000–2003. We directly examine the responses to the opinion survey’s questions regarding appropriate gender roles. The estimation results indicate that men raised by full-time working mothers are less likely to support traditional gender roles. Those men are also less likely to believe in the negative impact of a mother’s working on her children’s development.   相似文献

In sequencing problems for mixed-model assembly line in JIT production system, the Goal Chasing method (GC) is widely used for parts used leveling goal. The difference in assembly time of each product is not taken into consideration in the Goal Chasing method. Assembly time usually varies with product types. In recent years, the Time-Based Goal Chasing method (TBGC) has been proposed. The advantage of TBGC is to consider the influence of different assembly time of each product and idle time in production period. TBGC, however, has been only applied to single work station problems. In this paper, TBGC is applied to an assembly line problem with multiple work stations. Furthermore, the sequencing method and use of Simulated Annealing (SA) or Local Search (LS) for this problem are proposed.  相似文献

Assuming a statistical model in which the joint distribution of the unobservable errors is drawn from independent univariate Student t's that are identically and symmetrically distributed, the sampling performance of traditional robust estimators and a family of Stein-like estimators are compared and evaluated. These results suggest that under thick-tailed distributions, the relative sampling performances and risk characteristics for a range of nonconventional Stein estimators remains approximately the same as in the case of their normal counterparts. The empirical risk implications of misspecifying the error distribution are investigated.  相似文献

In the analysis of variance, we often encounter situations in which we want to test the null hypothesis of homogeneity of the normal means against various partially ordered alternative hypotheses. We study likelihood ratio tests for three useful types of alternatives: d-star, bipartite and broom tree. Especially, we give computational formulas for the level probabilities of the alternative types. The results permit us to obtain critical values for practical use.  相似文献

Abstract

With the role of libraries evolving from warehousing data sources to controlling the dissemination of information sources, A&I (abstracting and indexing) information services must also evolve and play an equally important and challenging role. With over forty years of A&I publishing experience, CSA (formerly Cambridge Scientific Abstracts) has adapted A&I publishing methods to new technologies and Web-based publishing. The editorial basics of producing A&I journals and databases are unchanged; however, new production technologies, such as electronic feeds between primary and secondary publishers, electronic directory services, and machine-aided indexing, can provide efficiencies. Once just roadmaps pointing to information, A&I services are now conduits delivering information directly to the user. Serials Review 2003; 29:221–223.  相似文献

This paper theoretically studies how unfunded pay-as-you-go social security affects economic growth, the fertility rate, and welfare in a neoclassical growth model. In addition, this paper considers a more general form of child-rearing cost, which is a mixture of time and money. The first observation is that whether the fertility rate increases or not by the expansion of the pay-as-you-go social security depends on (1) the size of the monetary child-rearing cost relative to the time spent on child-rearing and (2) the current fertility and interest rate in laissez faire. The second observation is that income per worker can increase by an expansion in pay-as-you-go social security when the output elasticity of capital is sufficiently small and the payroll tax rate is high. The last finding is that welfare can be improved even though capital is underaccumulated in an economy.  相似文献

While the sharply increased services for the elderly in the revised Gold Plan--announced in 1994--are noteworthy, implementation of the revised Plan is expected to present numerous issues and problems, particularly in the rural areas of Japan, because of unique circumstances such as depopulation and the presence of a disproportionately large number of elderly; geographical and physical isolation; a conservative and tradition-bound political climate; and conservative attitudes of the elderly. This article examines the current state of policy implementation, identifying issues and problems that are being encountered in the rural areas of Japan. Such issues as economic and family life, health care, and service delivery for the elderly are examined.  相似文献
