Immigration enforcement, and deportation in particular, has been shown to have social and psychological effects on the non-deported as well, but its political effects have gone largely unexamined. I use the staggered implementation of Secure Communities, an information-sharing program between the federal government and local law enforcement, to estimate the short-term effects of stricter immigration enforcement on Latino voter turnout. A difference-in-differences analysis indicates that enrollment in Secure Communities led to an increase in county-level Latino voter turnout of 2–3 percentage points. This relatively large effect appears due to greater Latino activism in the wake of program implementation, rather than individuals responding to particular police interactions. These results extend the existing literature on mobilization in response to threat, demonstrate that policies can have far-reaching and unexpected political implications, and suggest that the current immigration debate may have major consequences for the future makeup of the American electorate.  相似文献

This article examines the development, framing, and implementation of Proposition 35, the ‘Californians Against Sexual Exploitation Act.’ The 2012 ballot initiative, described variously as a measure against human slavery, human trafficking, and sex trafficking secured more votes than any other initiative or candidate in a single statewide election in California history. We argue that the measure exemplifies a disjuncture in the articulation of feminist politics against sexual violence, labor exploitation, and criticisms of the carceral state. The rise of the sex trafficker as a ‘spectral’ subject of contemporary political discourse shapes a broader ideological framework that permits a distinct set of political actors and interests to widen their institutional and political authority and to marginalize competing claims about the roots of sexual violence and labor exploitation. Proposition 35, which targets a ‘spectral’ figure abstracted from institutional context and relations of power, expands the carceral state in the name of protecting vulnerable women while also excluding long-standing feminist solutions to sex and gender-based violence.  相似文献

Abstract: A pilot study evaluated a computer‐based method for comparing digital dental images, utilizing a registration algorithm to correct for variations in projection geometry between images prior to a subtraction analysis. A numerical assessment of similarity was generated for pairs of images. Using well‐controlled laboratory settings, the method was evaluated as to its ability to identify the correct specimen with positive results. A subsequent clinical study examined longitudinal radiographic examinations of selected anatomical areas on 47 patients, analyzing the computer‐based method in making the correct identification based upon a threshold level of similarity. The results showed that at a threshold of 0.855, there were two false negative and two false positive identifications out of 957 analyses. Based on these initial findings, 25 dental records having two sets of full mouth series of radiographs were selected. The radiographs were digitized and grouped into six anatomical regions. The more recent set of films served as postmortem images. Each postmortem image was analyzed against all other images within the region. Images were registered to correct for differences in projection geometry prior to analysis. An area of interest was selected to assess image similarity. Analysis of variance was used to determine that there was a significant difference between images from the same individual and those from different individuals. Results showed that the threshold level of concordance will vary with the anatomical region of the mouth examined. This method may provide the most objective and reliable method for postmortem dental identification using intra‐oral images.  相似文献

This short-term longitudinal study investigated the simultaneous influences of adults’ (mothers and teachers) educational expectations and youth’s achievement (standardized test scores and teachers’ ratings of academic performance) across a 3-year time span on youth’s performance in school (GPA). Participants were an ethnically diverse sample of 426 low-income urban youth, ages 6 through 16 at T1. Results from cross-lagged and autoregressive path analyses indicated stability in adults’ expectations and youth’s standardized test scores; cross-lagged influences of teachers’, but not mothers’, expectations across time; and effects of youth’s achievement outcomes on adults’ expectations at T2, but not vice versa. Overall, the pattern of findings demonstrate that adults’ educational expectations are dynamic and responsive to how youth are faring in school and to changes in academic performance across time.

The exploratory study conducted by Yang, Burrola, and Bryan (2009) provides an excellent platform for calling attention to the issue of suicide risk among elementary and middle school youth. Using their study as a catalyst, with this commentary I consider the finding that 12% of the young people surveyed acknowledged that they had “seriously considered suicide during the past year.” I offer an alternative interpretation that focuses more explicitly on youth resilience and discuss how youth organizations can become more intentional and proactive in their overall suicide prevention aims.  相似文献

The new enclosures: critical perspectives on corporate land deals   总被引:1,自引:0,他引:1  
The contributions to this collection use the tools of agrarian political economy to explore the rapid growth and complex dynamics of large-scale land deals in recent years, with a special focus on the implications of big land deals for property and labour regimes, labour processes and structures of accumulation. The first part of this introductory essay examines the implications of this agrarian political economy perspective. First we explore the continuities and contrasts between historical and contemporary land grabs, before examining the core underlying debate around large- versus small-scale farming futures. Next, we unpack the diverse contexts and causes of land grabbing today, highlighting six overlapping mechanisms. The following section turns to assessing the crisis narratives that frame the justifications for land deals, and the flaws in the argument around there being excess, empty or idle land available. Next the paper turns to an examination of the impacts of land deals, and the processes of inclusion and exclusion at play, before looking at patterns of resistance and constructions of alternatives. The final section introduces the papers in the collection.  相似文献

ABSTRACT

Convergence – as an objective and as a process – designates the coming together of different social actors across strategic, political, ideological, sectoral and geographic divides. In this paper, we analyze the global food sovereignty movement (GFSM) as a convergence space, with a focus on constituencies and quotas as tools to maintain diversity while facilitating convergence. We show how the use of constituencies and quotas has supported two objectives of the GFSM: alliances building and effective direct representation in global policy-making spaces. We conclude by pointing to some convergence challenges the GFSM faces as it expands beyond its agrarian origins.  相似文献
