While states around the world have responded to mass mobility by increasing border policing, our knowledge of the daily reality of that form of policing remains limited. How migrant women are policed has been particularly neglected. The political and practical difficulty of examining the context, process and experience of border control practices appears often to be insurmountable. This article contributes to filling some of the gaps in our knowledge by drawing on ethnographic data collected over a 12-month period in Greek immigration detention centres from 2011 to 2012. In it we examine the experience of policing and irregular entry across the Greek Turkey border – an entry-point to Europe that is routinely regarded as being in crisis. As we will demonstrate, border policing at this site is capricious and unpredictable. It is also highly racialised and gendered.  相似文献

Scientific techniques for inventory management typically are applied to systems containing many items. Such techniques require an estimation of the demand variance (and mean) of each item from historical data. This research demonstrates a significant potential for improvement in system cost performance from using least-squares regression fits of a variance-to-mean functional relation instead of the standard statistical variance estimate. Even when there is a moderate degree of heterogeneity among items and when the form of the variance-to-mean relation is misspecified, substantial cost savings may be realized. The cost of statistical uncertainty may be reduced by half. The research also provides evidence that system cost is fairly insensitive to the number of items used to fit the regression. This paper provides the underlying reason why a regression-derived variance estimator yields lower cost: it is less variable than the usual individual item variance estimator.  相似文献

The transition from youth to adulthood in western societies has become more prolonged and complex as traditional societal norms have lost influence. Using retrospective data from a cohort of 43-year-old Canadians surveyed in 2010 (n?=?405), we mapped the timing, sequencing, and duration of ‘first stage’ youth-adult transitions (leaving home, finishing formal education, obtaining a full-time job) and ‘second stage’ youth-adult transitions (marriage, parenthood, home ownership). Latent profile analysis identified five distinct transition profiles – norm-setters, quick adults, uncertain adults, adult students, and delayed adults – with different amounts and timing of post-secondary educational investment playing an important profile-shaping role. Although youth-adult transitions have become less standardized and more individualized, especially for first stage transitions, these transitions are still quite structured and continue to be affected by gender and family socioeconomic status.  相似文献

Despite increased access to parenting rights through legal marriage and adoption, U.S. gay, lesbian, bisexual, transgender, and queer (GLBTQ) parents continue to experience varying levels of support for their families. This study explored protective strategies, or actions taken to meet one's safety needs when vulnerable, that GLBTQ parents pursue. This study included 454 GLBTQ parents from a national survey. Participants' open-ended responses about protective strategies were extracted from the survey and analyzed using content analysis. Responses were coded into 10 categories capturing strategies GLBTQ parents used to protect their families. While strategies utilizing legal supports were common, the most cited strategies were symbolic strategies, including creating a family name and developing written statements of parent wishes. Exploratory analyses revealed no difference in mean number of strategies used between parents who reported having legal status as a parent through adoption or listing on the birth certificate and those without legal parenting status. These results suggest that GLBTQ parents, regardless of their legal parenting status, take intentional measures to achieve a sense of safety and increase social support. The findings reiterate the importance of both legal and social support of GLBTQ parents.  相似文献

This article provides a review of the literature addressing the unique needs and experiences of queer fathers. Despite the growing number of queer fathers and families, and increasing scholarship on this topic, there is a major dearth in the counseling scholarship and practice related to queer families, or more specifically and especially, queer fatherhood. Thus, this article uses the concept of a “protective circle” to assist professional counselors to understand their vital role within a queer father and familial system. By understanding the experiences and needs of queer fathers, counselors can better conceptualize and assist this underserved and often silenced community.  相似文献

ABSTRACT

Incarcerated parents have complex life histories that often remain unresolved during incarceration, can continue to create barriers to prosocial success on release, and present similar intergenerational challenges for their children. This study examines the life histories of incarcerated fathers and mothers from the Pacific Northwest and how their experiences vary based on race and ethnicity. Five areas examined were exposure to trauma, child welfare involvement, mental health and substance abuse problems, juvenile justice and adult criminal justice involvement, and intergenerational criminal justice involvement. The sample comprised 359 incarcerated parents, and their racial/ethnic composition was 59% White, 14% African American, 11% multiracial, 8% Native American, and 7% Latino. Few differences were found across racial and ethnic groups. Mothers appeared more similar to each other across groups than fathers. Results illustrated similarities yet some surprising differences with national trends on key study variables. Implications for future research and intervention and prevention are discussed.  相似文献

A significant challenge in fitting metamodels of large-scale simulations with sufficient accuracy is in the computational time required for rigorous statistical validation. This paper addresses the statistical computation issues associated with the Bootstrap and modified PRESS statistic, which yield key metrics for error measurements in metamodelling validation. Experimentation is performed on different programming languages, namely, MATLAB, R, and Python, and implemented on different computing architectures including traditional multicore personal computers and high-power clusters with parallel computing capabilities. This study yields insight into the effect that programming languages and computing architecture have on the computational time for simulation metamodel validation. The experimentation is performed across two scenarios with varying complexity.  相似文献

Condoms protect against human immunodeficiency virus (HIV)/sexually transmitted infections (STIs) and unintended pregnancy and are essential to sexual health efforts targeting young adults, who are disproportionately affected by both outcomes. Understanding condom use motives is critical to increasing condom use. Research in this area is limited, particularly regarding the roles of partners and relationship factors. Using a longitudinal sample of 441 young adults and 684 reported partnerships we examined associations between relationship factors and condom use motives (pregnancy prevention, disease prevention, or dual protection). Simultaneous multilevel models identified variables associated with motives; level-specific models identified the levels (individual, partnership, time) variables impacted motives. Participants reported choosing condoms for pregnancy prevention, disease prevention, and dual protection in 51%, 17%, and 33% of partnerships, respectively. Partner-specific factors varied, to a differing degree, across the three levels. Seven variables (duration, condom self-efficacy, commitment, sexual decision-making, power, and vulnerability to harm [HIV/STIs] and pregnancy) distinguished condom use motives. The level of this association varied but was most pronounced at the partner and individual levels. Researchers and practitioners should consider the impact of both individual- and partner-level factors on condom use motives, in both research and sexual health programs.  相似文献

In the aftermath of Hurricane Katrina and the federal levee failures, hundreds of thousands of volunteers went to New Orleans to help rebuild. Food was quickly used as a way to welcome volunteers, to compensate them for their hard work, to celebrate progress in rebuilding community, and to interact with others. In time, however, the giving and consuming of food was renegotiated. Volunteers coming to New Orleans expected meals representative of New Orleans's foodways. This article looks at the cultural performance of food in the aftermath of Hurricane Katrina. In particular, I analyze the symbolic exchanges of food in what I call performances of reciprocity and performances of solidarity. This study adds to the burgeoning work in symbolic interaction on food, especially as it pertains to progressive spaces of cultural politics.  相似文献
