We use data from the Fragile Families and Child Wellbeing Study (N = 12,140 person-waves) to identify characteristics associated with mothers' having or lacking "personal safety net" support from family and friends. We focus on characteristics that are likely to increase the importance of having support available but may also interfere with the maintenance of supportive ties: poverty, poor physical and mental health, and challenging child rearing responsibilities. By capitalizing on distinctions among these types of personal disadvantages and among types of personal safety nets (financial, housing, child care, and emotional), we help to explain why personal disadvantages are associated with weaker support. Our paper contributes to the literature emphasizing the importance of reciprocity in support relationships and introduces the idea that families that are more difficult to help will have less support available. 相似文献

The purpose of the following study was to explore certain affective and cognitive components and their relationships to gambling
behavior in an undergraduate population. Specifically, the aim was to predict gambling severity using depression scores on
the BDI-II, the dependency and self-criticism subscales on the DEQ, emotional awareness scores on the LEAS, cognitive flexibility
scores from the STROOP, and a creativity subtests from the TTCT. Participants were 200 undergraduate students and 3.5–7.5%
of individuals reported some level of problematic gambling behavior. Multiple regression analysis indicated that self-criticism
and creative originality were significant predictors of gambling behavior, explaining 7.6% of the variance. Further analyses
reveal a non-linear trend in the creative originality of those who gamble; only the at-risk gamblers were high in creativity whereas abstainers and problematic gamblers display similarly lower levels of creativity.
Results are discussed in regards to Blaszczynski and Nower’s Addiction 97:487–499 (2002) subtypes of gambling vulnerability. 相似文献

This article describes local, state, and federal policies related to collecting, aggregating, and reporting data on student race and ethnicity in U.S. K-12 and postsecondary education. It traces data policy from the 1997 decision by the Office of Management and Budget to change from single-race reporting to a format that permits respondents to choose more than one race, to the October 2007 issuance of final guidance from the Department of Education. Taking a K-20 perspective, I consider how policies for data collection and reporting may affect educational and developmental outcomes for students, as well as local, state, and national education policy environments. 相似文献

This paper applies some general concepts in decision theory to a simple instrumental variables model. There are two endogenous variables linked by a single structural equation; k of the exogenous variables are excluded from this structural equation and provide the instrumental variables (IV). The reduced‐form distribution of the endogenous variables conditional on the exogenous variables corresponds to independent draws from a bivariate normal distribution with linear regression functions and a known covariance matrix. A canonical form of the model has parameter vector (ρ, φ, ω), where φis the parameter of interest and is normalized to be a point on the unit circle. The reduced‐form coefficients on the instrumental variables are split into a scalar parameter ρand a parameter vector ω, which is normalized to be a point on the (k−1)‐dimensional unit sphere; ρmeasures the strength of the association between the endogenous variables and the instrumental variables, and ωis a measure of direction. A prior distribution is introduced for the IV model. The parameters φ, ρ, and ωare treated as independent random variables. The distribution for φis uniform on the unit circle; the distribution for ωis uniform on the unit sphere with dimension k‐1. These choices arise from the solution of a minimax problem. The prior for ρis left general. It turns out that given any positive value for ρ, the Bayes estimator of φdoes not depend on ρ; it equals the maximum‐likelihood estimator. This Bayes estimator has constant risk; because it minimizes average risk with respect to a proper prior, it is minimax. The same general concepts are applied to obtain confidence intervals. The prior distribution is used in two ways. The first way is to integrate out the nuisance parameter ωin the IV model. This gives an integrated likelihood function with two scalar parameters, φand ρ. Inverting a likelihood ratio test, based on the integrated likelihood function, provides a confidence interval for φ. This lacks finite sample optimality, but invariance arguments show that the risk function depends only on ρand not on φor ω. The second approach to confidence sets aims for finite sample optimality by setting up a loss function that trades off coverage against the length of the interval. The automatic uniform priors are used for φand ω, but a prior is also needed for the scalar ρ, and no guidance is offered on this choice. The Bayes rule is a highest posterior density set. Invariance arguments show that the risk function depends only on ρand not on φor ω. The optimality result combines average risk and maximum risk. The confidence set minimizes the average—with respect to the prior distribution for ρ—of the maximum risk, where the maximization is with respect to φand ω. 相似文献

ABSTRACTHow can we best protect and safeguard the progress of the #MeToo movement? This article presents 11 reforms designed to ensure the movement’s drive toward justice. These fall into three areas. The first concern process reforms designed to (a) protect all those involved—accusers and the accused—in investigations of sexual harassment, (b) end differential treatment of those found guilty, and (c) ensure punishments are commensurate with the crime and proportional in terms of other transgressors. The second set of reforms focus on transparency of the process, including clarifying (a) how to file charges, (b) who makes decisions, (c) relevant public information on how charges and procedures are followed, (d) what transgressions result in which punishments, and (e) how complaints are investigated to protect the rights and privacy of all. Finally, I address cultural issues that address (a) our portrayal of women, (b) our societal attempts to prepare young people so they can better protect themselves, and (c) attempts to encourage bystanders to intervene in the face of sexual harassment of others. 相似文献

This study sought to examine school anxiety and depression by parents’ immigrant status and identify differences by region of birth and language proficiency. Data were used from the Early Childhood Longitudinal Study‐Kindergarten Cohort, a nationally representative and longitudinal study of students in the United States. The analytic sample included 6,156 youth. Linear regression models predicted school anxiety and depression of American eighth grade students from English proficiency and parents’ region of birth. Controlling for demographic covariates, there was no significant difference in school anxiety or depression between youth with American‐born parents and those with parents born in any major world region. With the inclusion of an interaction between language proficiency and region of birth, children with limited English proficiency from Europe (B = 2.86, 95% CI = 2.16, 3.55), Central America (B = 1.52, 95% CI = 0.73, 2.31), Asia (B = 1.48, 95% CI = 0.55, 2.40), and South America (B = 0.85, 95% CI = 0.08, 1.61) had significantly heightened school anxiety compared to native‐English speakers with native‐born parents. When considering sources of school anxiety, it was revealed that over 60% of these youth worried about doing well in school. Future research should explore interventions to increase English proficiency and ease school‐related stress among children of immigrants. 相似文献

This article proposes to extend the work of law and film scholars, such as Carol Clover and Jennifer Mnookin, by looking at how juridically themed documentary films use the legal trial as both a platform and a structuring device to contest the evidentiary value of testimony, bear witness to the performance of law in our culture and engage in a social debate about flaws in contemporary jurisprudence. Because non-fiction film – with its presumed indexical relationship to reality and its attendant claims to authenticity – is often seen as having a privileged relationship to truth, the ethical and epistemological stakes of these visual representations are heightened. Consequently, the expectations we bring to the juridical documentary (in terms of its truth-telling responsibilities) make it a particularly loaded space for analysing the ethical and epistemological responsibilities of documentary representation as well as for revealing truths about the legal process and the ordering of a just society. Thinking through the ways in which contemporary trial documentaries differently approach the question of their subjects' guilt allows us to reflect on how the juridical documentary refracts the legal trial's own truth claims. These documentary films demonstrate that, while the documentary and the legal trial might share an epistemological affinity based on shared principles of evidence, narrative and argument, the way in which the trial itself is thematized as both a discourse and a practical purveyor of justice in documentary influences how we come to understand the law in action. 相似文献

This article examines what happens when an employee makes the transition from one recognized gender category to another and remains in the same job. Drawing on in‐depth interviews with transmen and transwomen in Texas and California, we illustrate how a new social gender identity is interactionally achieved in these open workplace transitions. While transgender people often are represented as purposefully adopting hyper‐feminine or masculine gender identities post‐transition, we find that our respondents strive to craft alternative femininities and masculinities. However, regardless of their personal gender ideologies, their men and women co‐workers often enlist their transitioning colleague into gender rituals designed to repatriate them into a rigid gender binary. This enlistment limits the political possibilities of making gender trouble in the workplace, as transgender people have little leeway for resistance if they wish to maintain job security and friendly workplace relationships. 相似文献

Scientists, activists, industry, and governments have raised concerns about health and environmental risks of nanoscale materials. The Society for Risk Analysis convened experts in September 2008 in Washington, DC to deliberate on issues relating to the unique attributes of nanoscale materials that raise novel concerns about health risks. This article reports on the overall themes and findings of the workshop, uncovering the underlying issues for each of these topics that become recurring themes. The attributes of nanoscale particles and other nanomaterials that present novel issues for risk analysis are evaluated in a risk analysis framework, identifying challenges and opportunities for risk analysts and others seeking to assess and manage the risks from emerging nanoscale materials and nanotechnologies. Workshop deliberations and recommendations for advancing the risk analysis and management of nanotechnologies are presented. 相似文献
