This article seeks to expand knowledge about spontaneous volunteering in Amsterdam during the European refugee crisis in the winter of 2015–16. As formal institutions, which relied on a top–down command and control approach, were unable to handle the relatively large number of refugees who arrived in a short period of time, grassroots social movements based on bottom–up participation emerged. Grassroots volunteers were not only politically engaged, protesting against the strict refugee reception policy, but they also became involved in the crisis response, showing a great deal of flexibility. Although the social movements struggled with their organizational structures, they were able to adapt their missions and structures to changing circumstances. To achieve a resilience‐based response to future refugee influxes, this article advocates for formal response organizations to dismantle their static, top–down approach, and for social movements to find a balance between participation and professionalism. If institutionalized refugee response organizations adapt to the dynamics of local conditions, they could create the conditions for resilient solutions in the crisis context. 相似文献

The sexual health problems experienced by homeless youth bring into question their use of available sexual health services. Using a qualitative typological analysis, this study aims to identify sexual health services utilization profiles for homeless youth, and to understand the role of the homeless experience on the utilization of sexual health services. Individual interviews were conducted with 33 homeless youth (17 men, 16 women) between 18 and 25?years of age. Typological analysis identified four profiles: (1) a targeted use of sexual health services to determine one’s serological status following a relational change during the homeless experience; (2) a limited use of sexual health services to manage sexual emergencies that arise during the homeless experience; (3) a regular use of sexual health services to avoid the risks associated with the homeless experience; (4) a frequent use of sexual health services to obtain support when engaging in prostitution during the homeless experience. This study shows that the precarious and unstable conditions within the homeless experience incite youth to utilize sexual health services in different ways. These findings point to the importance of rethinking sexual health services to better adapt them to the different utilization profiles of homeless youth. 相似文献

Economic uncertainty contributes to low fertility in many European countries. On the other hand, greater gender equality may positively influence fertility. This paper examines how these two forces interact in Spain. We use in-depth interviews to analyse fertility decision-making among young and highly educated partnered adults living in urban areas. Highly gender-egalitarian interviewees are less likely to perceive economic insecurity as an obstacle to proceeding to a next birth than less egalitarian interviewees. But there is not necessarily a difference in these two groups’ overall fertility intentions, as highly egalitarian interviewees’ greater valuation of stable employment for both partners requires institutional and policy support for dual-earner couples’ childrearing. When we look only at interviewees who express economic insecurity, somewhat higher fertility intentions are expressed by those holding less gender-egalitarian attitudes. Our results underline the complexity of the interrelationships between economic insecurity, gender egalitarianism, and fertility intentions. 相似文献

Activist burnout scholarship has inadequately considered challenges marginalized-identity activists, such as racial justice activists of color, experience in the course of their activism – challenges from which privileged identity activists, such as white racial justice activists, are protected. This article attempts to address this gap through a phenomenological study examining activist burnout in racial justice activists of color whose primary sites of activism are predominantly white colleges and universities in the United States at which they work. In order to stretch activist burnout theory to differentiate unique marginalized-identity activists’ burnout causes from general causes that do not consider specific activist identities, the lens of racial battle fatigue is employed. Findings show that, although participants shared many causes of burnout that are consistent with general non-identity-specific causes described in existing literature, racial battle fatigue hastened their burnout while their activist commitments elevated their battle fatigue. 相似文献

In the 1967 Harvard-Cornell football game, Harvard was ahead 14–0 late in the game when Cornell scored two touchdowns. On both occasions, Cornell tried and failed on the two-point conversion attempt and lost the game 14–12. Postgame arguments were divided on the merits of Cornell's strategy. For this frequently occurring scenario in college football, we derive a maximum expected utility decision rule for the decision of kicking versus running/passing based on the relative utility of a win, a tie, or a loss and the probabilities of success with a kick as opposed to a run/pass. 相似文献

Environmental scanning activities of over 400 top management subunits in 108 European manufacturing firms provided the data base for this research. Four traits (constructs) of scanning using three methods (interest, frequency, and time) were examined. A confirmatory factor analysis approach to multitrait-multimethod (MTMM) data was employed. Verification of the reliability as well as convergent and discriminant validity of the scanning scales are reported and discussed. The viability of confirmatory factor analysis in providing a precise analysis of partitioning variance according to trait, method, and error is demonstrated. 相似文献

This paper presents an inventory problem related to the one-period stochastic inventory (or “newsboy”) problem. In this problem, the firm has to decide how much product to order to meet a random one-period demand. The version of the problem presented is novel in two respects. First, demand is explicitly permitted to be negative, and second, the penalty (or shortage) cost is assumed to be independent of the magnitude of the shortage. This situation is shown to change the form of the cost function and to complicate the determination of optimal policies. The form of the optimal policy is developed, and two example problems are presented in some detail. 相似文献

The application of optimization techniques in digital simulation experiments is frequently complicated by the presence of large experimental error variances. Two of the more widely accepted design strategies for the resolution of this problem include the assignment of common pseudorandom number streams and the assignment of antithetic pseudorandom number streams to the experimental points. When considered separately, however, each of these variance-reduction procedures has rather restrictive limitations. This paper examines the simultaneous use of these two techniques as a variance-reduction strategy in response surface methodology (RSM) analysis of simulation models. A simulation of an inventory system is used to illustrate the application and benefits of this assignment procedure, as well as the basic components of an RSM analysis. 相似文献

While it is well known that the widowed suffer increased mortality risks, the mechanism of this survival disadvantage is still
under investigation. In this article, we examine the quality of health care as a possible link between widowhood and mortality
using a unique data set of 475,313 elderly couples who were followed up for up to nine years. We address whether the transition
to widowhood affects the quality of care that individuals receive and explore the extent to which these changes mediate the
elevated mortality hazard for the widowed. We analyze six established measures of quality of health care in a fixed-effect
framework to account for unobserved heterogeneity. Caregiving and acute bereavement during the transition to widowhood appear
to distract individuals from taking care of their own health care needs in the short run. However, being widowed does not
have long-term detrimental effects on individuals’ ability to sustain contact with the formal medical system. Moreover, the
short-run disruption does not mediate the widowhood effect on mortality. Nevertheless, long after spousal death, men suffer
from a decline in the quality of informal care, coordination between formal and informal care, and the ability to advocate
and communicate in formal medical settings. These findings illustrate women’s centrality in the household production of health
and identify important points of intervention in optimizing men’s adjustment to widowhood. 相似文献

Obesity is considered a major cause of premature mortality and a potential threat to the longstanding secular decline in mortality
in the United States. We measure relative and attributable risks associated with obesity among middle-aged adults using data
from the Health and Retirement Study (1992–2004). Although class II/III obesity (BMI _ 35.0 kg/m2) increases mortality by
40% in females and 62% in males compared with normal BMI (BMI = 18.5-24.9), class I obesity (BMI = 30.0-34.9) and being overweight
(BMI = 25.0-29.9) are not associated with excess mortality. With respect to attributable mortality, class II/III obesity (BMI
_ 35.0) is responsible for approximately 4% of deaths among females and 3% of deaths among males. Obesity is often compared
with cigarette smoking as a major source of avoidable mortality. Smoking-attributable mortality is much larger in this cohort:
about 36% in females and 50% in males. Results are robust to confounding by preexisting diseases, multiple dimensions of socioeconomic
status (SES), smoking, and other correlates. These findings challenge the viewpoint that obesity will stem the long-term secular
decline in U.S. mortality. 相似文献
