Much has been written about the problems of combining job and family. Among the best-known scholarly works is Goldin’s (1997) study in which she found that only 12–17 percent of college-educated women managed to attain both a career and a family. We re-examine these conclusions, first duplicating Goldin’s definitions of career but using a somewhat older group, then using alternate definitions of career. We reach far more optimistic conclusions about what lies ahead for today’s college women.  相似文献

Abstract

Nations engaged in a dispute may escalate their use of coercion in order to raise the costs of the fight to the other side and gain concessions. As a fight continues, escalation is made more probable by changes in the motivation and the expectations of the participants. The goals of each participant may expand and winning the dispute may become more important than it was initially. Each may come to expect the other to increase its coercion beyond previous boundaries and no longer see the prospect of a negotiated settlement. In addition, normative and other inhibitions on the use of force tend to decrease once the use of coercion has begun. The ways in which a conventional war might escalate to a nuclear war are discussed. The conditions under which deescalation of coercion will occur are outlined.  相似文献

The nonschool hours are an underused tool in supporting older youth in their transition to adulthood. Given competing demands on many teens' time and a host of other developmental realities, effective strategies for engaging high schoolers look much different from those of their younger counterparts, and those differences have programmatic and policy implications. Effective youth policies reflect an overarching vision that is about changing lives--a vision that addresses a range of risk and protective factors, simultaneously supports discrete programs and builds coherent pathways to success, and recognizes that children and youth grow up in families and communities. This chapter highlights policy innovations related to teens' involvement in out-of-school-time activities and then looks at three principles that can help ensure that youth policy supports the full range of older youth's unique developmental, social, and economic needs.  相似文献

Worldwide changes are altering the conditions under which adolescents prepare for adulthood and are increasing the need for thoughtful, tailored, youth policies and programs. This article offers a set of “framing questions” aimed at helping countries and communities create policies that are adapted to the particulars of a given context. These questions are presented as a means for policy makers, advocates, practitioners, researchers, community members, parents, and adolescents to formulate services, supports, and opportunities that will help adolescents become adults who are problem free, fully prepared, and fully engaged in their communities.  相似文献

In recent years, the study of race and ethnicity has expanded, and there is now a growing field of research that examines whiteness and racial privilege. This article provides an overview of theories of privilege and whiteness studies, and argues that these analyses should incorporate an intersectional approach. Intersectional theories argue that race and gender are intertwined, and neither can be fully comprehended on its own. An intersectional approach sees race and gender as interacting and inseparable. Two specific contemporary racial projects are examined: the ideology of color blindness, and organized white supremacist discourse, and argues that gender is essential to understanding both. Finally, the consequences of the erasure of gender from our analyses of whiteness are examined.  相似文献

We consider two capacity choice scenarios for the optimal location of facilities with fixed servers, stochastic demand, and congestion. Motivating applications include virtual call centers, consisting of geographically dispersed centers, walk‐in health clinics, motor vehicle inspection stations, automobile emissions testing stations, and internal service systems. The choice of locations for such facilities influences both the travel cost and waiting times of users. In contrast to most previous research, we explicitly embed both customer travel/connection and delay costs in the objective function and solve the location–allocation problem and choose facility capacities simultaneously. The choice of capacity for a facility that is viewed as a queueing system with Poisson arrivals and exponential service times could mean choosing a service rate for the servers (Scenario 1) or choosing the number of servers (Scenario 2). We express the optimal service rate in closed form in Scenario 1 and the (asymptotically) optimal number of servers in closed form in Scenario 2. This allows us to eliminate both the number of servers and the service rates from the optimization problems, leading to tractable mixed‐integer nonlinear programs. Our computational results show that both problems can be solved efficiently using a Lagrangian relaxation optimization procedure.  相似文献
