Team up to meet child-care needs 总被引:1,自引:0,他引:1
Thaler-Carter RE 《HRMagazine : on human resource management》1990,35(3):44, 46, 48
Recognizing the importance of child care is not the same as providing it. The options for many employees are limited, but some employers are trying to assist employees with their child-care needs. One option that benefits many small to medium-sized companies is a child-care consortium. 相似文献

Recent theoretical developments have incorporated endogenous multinational firms into the general–equilibrium model of trade. One simple taxonomy separates the theory into "vertical" models, in which firms geographically separate activities by stages of production, and "horizontal" models, in which multiplant firms duplicate roughly the same activities in many countries. The authors nest a horizontal and a vertical model within a hybrid (unrestricted) "knowledge–capital model" and estimate the specifications with data on US foreign direct investment activity. In the nested econometric tests, the data sample cannot distinguish statistically between the unrestricted model and the restricted horizontal model, indicating that the latter captures virtually all of the determinants of FDI. The tests overwhelmingly reject the vertical model. 相似文献

The purpose of the present study was to explore the role of personality in shaping consumer innovativeness by testing a model of the hierarchical relationships between a global (broad or abstract) personality trait, its domain-specific manifestation in a consumer context, and overt consumer behavior. A survey of 465 adult consumers measured global innovativeness, domain-specific innovativeness for two product categories (clothing and electronics) and self-reported purchase of new clothing and electronic items. Three hypotheses were tested. First, global innovativeness is more highly correlated with domain-specific innovativeness than it is with the purchase of new items. Second, domain-specific innovativeness is more highly correlated with the purchase of new items than is global innovativeness. Finally, the association between global innovativeness and new product purchase is mediated by domain-specific innovativeness. All three hypotheses were supported for both product categories. 相似文献

"This paper describes the methodology used to incorporate AIDS mortality in recently revised World Bank population projections....The paper first reviews different approaches for projecting AIDS and its demographic consequences. This is followed by a summary of an epidemiological model that simulates the spread of HIV used in this analysis, and a demographic model that translates mortality from AIDS into population outcomes. These models are then used in a set of simulations, from which the effect of current HIV prevalence on projected future mortality is extracted. Finally, the extracted equations linking current HIV prevalence with future mortality indicators are applied to sub-Saharan countries with a measurable level of current HIV prevalence." 相似文献

This study is concerned with one aspect of the family cycle, namely, the transition from young married to young married with small children. The focus is on developing models to forecast entries into this latter stage for the purpose of marketing research. "Using ordinary least squares, forecasting models were estimated for (1) total number of first births, (2) number of white first births, and (3) number of nonwhite first births." Models are estimated for both the United States and California using data from official sources. 相似文献

Loren E. Lomasky 《American journal of economics and sociology》2004,63(1):189-205
ABSTRACT . In this article, Loren Lomasky begins with a firsthand account of some of the people he interacted with at the Center for the Study of Public Choice in Blacksburg and some of what he learned there. Aside from the revealing personal anecdotes, we learn something of the culture clash he experienced as a visiting fellow at the Center and about his introduction to intellectual activity as “blood sport.” Lomasky then reviews some of the strengths and weaknesses of public choice theory from a philosophical point of view and offers some suggestions. These primarily concern the theory's narrow focus on the material nature of interests. Finally, Lomasky offers techniques for including moral interests in the deliberations of decision makers. 相似文献
