Caregiving to family members comprises a major part of familial obligations in the United States. Informal caregiving is unevenly
distributed in society, with women performing most of the work and bearing the burden of its costs. This paper addresses the
cost dimension of informal caregiving to family members by examining whether and how it penalizes women’s employment. Drawing
data from the 1987 and 1992 National Survey of Families and Households, we examine whether and how caregiving transitions
affect changes in women’s labor force participation and the implications of this caregiving transitions for their earnings.
We calculate how these effects vary for demographically different groups of women: those older and younger, with and without
high levels of education, and married and not married. Our findings reveal that for most women, the initiation of caregiving
led to a substantial reduction in their weekly hours worked and annual earnings. However, the effects were different for various
subgroups of women: those older, with fewer skills, and more competing roles paid substantial costs if they began caregiving
between 1987 and 1992. 相似文献

Using historical census microdata, we present a unique analysis of racial and gender disparities in destination selection and an exploration of hypotheses regarding tied migration in the historical context of the Great Migration. Black migrants were more likely to move to metropolitan areas and central cities throughout the period, while white migrants were more likely to locate in nonmetropolitan and farm destinations. Gender differences were largely dependent on marital status. Consistent with the "tied-migration" thesis, married women had destination outcomes that were similar to those of men, whereas single women had a greater propensity to reside in metropolitan locations where economic opportunities for women were more plentiful. 相似文献

The OECD social indicators for 2001 were critically reviewed by analysing their interrelationships across all OECD countries during the late 1990s. First, findings were provided covering the underlying structure of subsets of indicators by similarity in content as suggested by the OECD. Second, an analysis of the selected key indicators yielded five social dimensions, which were interpretedas conceptual constructs underlying the set of OECDsocial indicators at the level of the entire OECD area. Third, the relationships of each indicator withthese social dimensions were observed to aid choosing of appropriate indicators for making and evaluating social policies. Fourth, the OECDcountries were ranked according to their overall social welfare, as defined by the OECD social indicators, basedon the scores of the countries on the social dimensions. Fifth, similarities among the OECD countries were examined and it was found that the countries formed six bipolar country dimensions. The findings showed that an easily interpretable structure underlies the OECD social indicators. The paper clarified the use of the OECD social indicators for 2001 as a tool for planning and decision-making and for cross-national analyses of social policies. 相似文献

Background: The Item Response Theory (IRT) has advantages for measuring Health Related Quality of Life (HRQOL) as opposed to the Classical
Tests Theory (CTT). Objectives: To present the results of the application of a polytomous model based on IRT, specifically, the Rating Scale Model (RSM),
to measure HRQOL with the EORTC QLQ-C30. Methods: 103 terminal cancer patients cared for by the home services of the Servicio Andaluz de Salud (Andalusian Health Service)
(Andalusia, Spain) participated. These patients responded to the adapted Spanish version of the EORTC QLQ-C30. The application
was carried out individually in the patients’ homes. Results: The results show that there is an adequate global fit between the data and the IRT model applied. The analysis of the items
shows that for 31 of the 33 items there is a good fit. The items which measure the general perception of health and the perception
of quality of life present a lack of fit. The study of the response categories of the items (by means of Category Probability
Curves) indicates that all the alternatives work extremely well. Conclusions:The EORTC QLQ-C30 presents good metric qualities, under the RSM, ratifying the feasibility to measure HRQOL already shown
in other studies carried out with CTT. 相似文献

Hill's theory that the positive association between light skin color and intelligence among African Americans can be explained as a result of discrimination by whites against darker skinned blacks is implausible. There is no direct evidence for this theory. If it were true, dark skinned blacks should earn less than light skinned blacks as a result of greater discrimination against them. The NORC data show that this is not the case. Hill's analysis is an example of the Sociologists' Fallacy that consists of treating correlates as causes. 相似文献

The nations of the Middle East have arrived at a historic crossroad.Anchored in centuries-old political and economic systems, bitterethnic rivalries, recurrent intra-regional warfare, and risingfundamentalism, the majority of the regions countries haveremained largely apart from the transformative processes that areshaping development in other world regions. Indeed, the impressionexists that no development miracles are occurring in theMiddle East and that, to a very great extent, the region isseeking to remain on the sidelines of modern history. And,yet, if the countries of the Middle East are to flourish in thenext century they, too, must restructure themselves for dealingwith the complex realities associated with increasing globalizationand internationalization. This paper reports on the socialdevelopment successes and failures of 22 Middle Eastern countriesbetween 1970 and 1997. Also identified are the regions SocialLeaders (SLs), Socially Least Developing Countries (SLDCs),and Middle Performing Countries (MPCs). The social, political,and economic factors most closely associated with each countrysdevelopment classification are identified. 相似文献

Summary Overwintering of two social halictine bees,Lasioglossum duplex (Dalla Torre) andL. problematicum (Blüthgen), was studied. InL. duplex many females stay near the old nests, each female preparing a hibernaculum separated from the natal nest. InL. problematicum most females overwinter communally within the natal nest. This difference in overwintering habits relates to the social structure
in the next spring.L. duplex is nearly always solitary in spring although later becoming eusocial, whereas many nests ofL. problematicum are polygynous, beginning in early spring.L. duplex overwinters much deeper (
) in the soil than doesL. problematicum (
), but both species are safe from drops in soil temperature, which is above 0°C even in midwinter, and the bees' supercooling
points are lower than −6°C. This cold resistance and the storage of sufficient food in the crop are reflected in the winter
survival, which is much higher (79%) than the rate of successful nests in the spring active phase (25%).
