The perception that young women are disengaged from feminist politics has provoked a great deal of tension between feminist generations. Recent feminist research into generational change has largely avoided this tension by focusing on the shifting meanings of feminism and the discrepancy between young women's reluctance to identify as “feminists” and their general acceptance of feminist attitudes toward gender issues. Nevertheless, in an era when gender equity goals seem to be if not slipping backwards then lacking urgency, young women are less likely to identify with a collective feminist politics than are older women. Underpinned by the findings of a major study of the attitudes toward work, family, and retirement of three generations of Australian women, this paper develops an approach that helps explain this reluctance. Drawing on the work of Karl Mannheim, the paper suggests that the cultural currents shaping the consciousness of different generations of women impact significantly on gender identity. The implications of this cultural shift are considered in the context of feminist politics and the contemporary “culture wars.” 相似文献

Over the past 20 years, researchers have demonstrated that ethnic identity in adolescence is multifaceted and dynamic, encompassing a number of aspects of content and self‐definition. The present study examines private regard (i.e., youths' positive evaluations of their ethnic group) as well as public regard, which refers to their perceptions of others' evaluations of the group. The primary objective of the present study was to examine stability versus change in private and public regard among an ethnically diverse sample of early adolescents as they progressed through middle school. Using data from a longitudinal investigation of 6th graders, we found that private regard was stable over time and quite positive for all groups. In addition, while Chinese American youths' public regard tended to increase over time, African American, Puerto Rican, and Dominican youths' public regard decreased across the middle school years. Implications for ethnic identity theory are discussed. 相似文献

Insulin-like growth factor 1 (IGF-1) signaling modulation has been associated with increased lifespan in model organisms, while high levels of circulating interleukin-6 (IL-6) are a marker of disability and mortality. In the prospective, population-based "Treviso Longeva"--TRELONG Study from Italy (n = 668, age range 70-105.5 years at baseline, followed for seven years) we investigated the effects of survival on the IGF-1 receptor (IGF-1R) gene polymorphism rs2229765, the IL-6 gene promoter polymorphism rs1800795, and plasma concentrations of IGF-1 and IL-6, alone or in combination. We found a sex-dependent effect for the IGF-1R rs2229765 polymorphism, as male carriers of the homozygous A/A genotype survived longer, while the IL-6 rs1800795 genotype did not influence overall or sex-specific longevity. Higher IL-6 levels were more detrimental for survival among males than females, while IGF-1 had no dose-response effect. These findings sustain the hypothesis that sex-specific longevity relies on detectable differences in genetic and biochemical parameters between males and females. 相似文献

Every production planning concept that incorporates controlled order release will initially withhold jobs from the shop floor and create a pre‐shop pool. Order release is a key component of the Workload Control concept that aims to maintain work‐in‐process within limits while ensuring due dates are met. Order release includes two decisions: (i) a sequencing decision that establishes the order in which jobs are considered for release; and, (ii) a selection decision that determines the criteria for choosing jobs for release. While selection has received much research attention, sequencing has been largely neglected. Using simulation, this study uncovers the potential for performance improvement in the sequencing decision and improves our understanding of how order release methods should be designed. Although most prior studies apply time‐oriented sequencing rules and load‐oriented selection rules, analysis reveals that load balancing considerations should also be incorporated in the sequencing decision. But an exclusive focus on load balancing is shown to increase mean tardiness and, paradoxically, require high workloads. A new sequencing rule is developed that only balances loads when multiple orders become urgent. It avoids high mean tardiness and allows the shop to operate at a low workload level. At the same time, the percentage tardy is reduced by up to 50% compared to a purely time‐oriented rule. The findings have implications not only for Workload Control but for any concept that features order release control, such as ConWIP and Drum‐Buffer‐Rope. 相似文献

The impact of state-level restrictions on abortion 总被引:1,自引:0,他引:1

This research examines 23 different laws passed by state governments in an effort to restrict the number of abortions. It assesses both laws passed and laws actually enforced after the Supreme Court permitted states to restrict access to abortion in 1989. None of the policy actions by state governments has had a significant impact on the incidence of abortion from 1982 to 1992. Abortion rates continue to reflect past abortion rates, the number of abortion providers, whether the state funds abortions for Medicaid-eligible women, urbanism, and racial composition of the population. Recent restrictive policies have not affected these trends. 相似文献

In 2010 the U.S. Census Bureau will achieve its goal of eliminating the long form sample from the decennial census and will produce its first set of five-year data products from the full sample American Community Survey (ACS). This paper provides an overview of the call for change that prompted the Census Bureau to pursue the development of a new approach to collecting socioeconomic and housing data. The paper details the evolution of the ACS from its earliest origins to its current design and describes that design in detail. The current design has benefited from external debate and consultation. Work such as that described later in this journal exemplifies the key role that external users and advisors have played, and will continue to play, in the evolution of the ACS. Over the past 10 years, the Census Bureau has undertaken research and testing to demonstrate operational feasibility and to assess survey quality. Research has also compared ACS and Census 2000 data. ACS staff are involved in survey improvement efforts and continue to confront survey challenges. In the next few years the ACS will give priority to developing user tools to aid all users in the correct interpretation of multi-year estimates. The ultimate validation of the ACS is, however, in the hands of users. Continued input from the people who are responsible for administering and evaluating programs, identifying local needs, and planning for the future will allow the ACS to grow in value and utility. 相似文献

Population and land use change in the California Mojave: Natural habitat implications of alternative futures 总被引:6,自引:0,他引:6

Demographic and land use dynamics have important implications for the natural environment within both developed and developing nations. Within the context of developed nations, popular and policy debates surrounding contemporary patterns of suburbanization attest to the salience of demographic and development issues. We examine the implications of land-use patterns as related to population and development within the context of the California Mojave Desert ecosystem. In a general sense, we aim to better understand the land requirements inferred by varying levels of population growth and density, as well as the natural habitat implications of those requirements. We develop a GIS including remotely sensed imagery, and demographic, economic, and biophysical data to examine of the implications of various demographic scenarios on species diversity. Spatial and statistical models are designed to develop possible alternative land use `futures'. Within the context of the California Mojave region, our results suggest that high-density development could reduce conflict with regions providing potential habitat for threatened or endangered species by over 80 percent. The process of model development demonstrates a potentially useful tool for policymakers, allowing for estimation and visualization of the land use implications of policy decisions. 相似文献

This paper examines post-migration investments in schooling and job search of immigrant families using new longitudinal data
for Australia. Higher education levels at the time of arrival are associated with a greater probability of enrolling in school
after migration. In households where the visa category would suggest that post-migration investments might be important, we
find higher rates of school enrolment and job search. Traditional gender roles appear to dictate which partner makes the investments
in formal schooling. However, labour market advantage, captured by principal applicant status, appears to dictate which partner
makes greater investments in job search.

The inter- and intra-state migration of American families with work-disabled members is a neglected area of empirical study. Longitudinal migration and health status data from the 1996 Panel of the Survey of Income and Program Participation (SIPP) are merged with state-level welfare policy indicators to investigate migration behavior under welfare reform’s emphasis on requiring work and encouraging reliance on social support networks. We use a nested discrete-choice event history model that incorporates the departure decision and interstate destination choice in a single model that tests the effects of state-level welfare policy and economic opportunity characteristics, with state fixed effects, plus family sociodemographic characteristics and social networks, as the basis for comparing migration of families with and without work disabilities. The results show that although families with disabilities and illnesses are less likely to migrate than other families generally, they are “pushed” to migrate if they live in states that do not exempt them from TANF activities requirements. Furthermore, in-migration is inhibited by stringent state welfare illness exemption rules and high state unemployment rates. Intrastate migration is more likely among families who received family and community social support, regardless of work-disability status. 相似文献
