Which individuals are most responsive to get-out-the-vote (GOTV) messages that emphasize the social aspects of voting? Recent literature has shown that GOTV messages that emphasize the social environment in which an individual is embedded are particularly effective at increasing voting rates. Until now, we have not had good estimates for the types of people for whom social GOTV messages are most effective. We report a new set of disaggregated results of a randomized controlled trial of political mobilization messages delivered to 61 million Facebook users during the 2010 U.S. Congressional elections. The results suggest that social endorsement cues are differentially effective for different types of political behaviors—political expression, information seeking, and voting—and for different kinds of people, based on both demographic and social characteristics, raising new questions about the mechanisms explaining social pressure effects.  相似文献

This is a reflection on the visual installation piece, Hanging On, produced collaboratively for the Feminist Legal Studies ‘At the Kitchen Table’ zine in 2016. The author and co-artist considers the research that informed and helped conceptually drive the aesthetics of the piece, including academic research on abortion within literary aesthetics. How these concepts ‘translated’ into hands-on artistic practice and physical materials is discussed, including the difficulties and knowledge gained from the process. The author finally considers the benefits of such interdisciplinary, aesthetic encounters within contemporary feminist knowledge production.  相似文献

This paper reports the findings of a study that investigates the factors affecting the re‐entry and readjustment process of returnee government scholars in Vietnam. These returnee scholars were originally sent overseas to study as part of changes introduced by the Vietnamese government to develop its domestic talent pool. Using the perspective of home country embeddedness, we find that career and community embeddedness factors, together with readjustment factors, have an effect on returnee scholars’ career and life satisfaction in their home country. These factors subsequently affected their intention to stay or re‐expatriate. The study contributes to public sector change management theory by examining factors affecting the re‐entry process of returnees within an emerging transition economy. It also adds to the limited studies on understanding and managing the re‐entry processes and state‐led diaspora strategies among returnee government scholars from emerging transition economies and their effectiveness.  相似文献

Although there is growing recognition of the problem of dating violence, little is known about how it unfolds among young adolescents who are just beginning to date. This study examined classes (subgroups) and transitions between classes over three time points based on dating violence, bullying, and sexual harassment perpetration and victimization experienced by youth. The sample was ethnically diverse, consisting of 795 seventh-grade students from schools that were part of a multi-site, longitudinal evaluation of a dating violence initiative (50 % female; 27 % White, 32 % African American, 25 % Latino, 16 % other or multiple races). Results from latent transition analyses revealed five classes of students with distinct behavioral profiles: multi-problem (victimization and perpetration), bullying and sexual harassment (victimization and perpetration), bullying (victimization and perpetration) and sexual harassment (victimization only), bullying (victimization and perpetration), and a least problem group. The majority of classes were characterized by reports of both perpetration and victimization for at least one behavior. Girls were more likely to be in the less problematic classes. Class membership was fairly stable across the three time points. When students transitioned to a different class, the shift was most often from a more problematic to a less problematic class, particularly for girls. The findings support understanding dating violence within a dynamic, developmental process that recognizes related behaviors within and across individuals. Overall, the findings highlight the utility of person-oriented approaches to enhance our understanding of longitudinal profiles and transitions over time for dating violence and related behaviors.  相似文献

This article examines the prediction of recidivism using the Global Risk Assessment Device (GRAD), a reliable and valid measure of dynamic factors associated with family characteristics, peers, mental health, substance abuse, trauma exposure, educational concerns, accountability, and health risks. Using a sample of adult caregivers of first-time misdemeanant offenders, two factors-education and accountability-were significantly associated with recidivistic behavior, supporting the use of GRAD data in correctly identifying first-time offenders who have the greatest and the least likelihood for future offending behavior. Additional analyses utilizing parent reports on African American males indicate that the GRAD provides discrimination in the prediction of recidivism in a group typically seen as being high risk simply because of their gender and race. The assessment drives intervention approach of the GRAD is discussed in terms of using reports from adults to accurately place youth into appropriate levels of supervision and treatment.  相似文献

A comparison study of the effects of environmental conditions on the development of latent fingermarks on raptor feathers using green magnetic fluorescent powder was undertaken using both sebaceous loaded and natural fingermark deposits. Sparrowhawk feathers were stored in indoor conditions for 60?days (Study 1), and buzzard feathers were left exposed to two different environmental conditions (hidden and visible) for 21?days (Study 2), with developments made at regular ageing periods. In Study 1, latent fingermarks were successfully developed (Grade 1–4) on the indoor feathers up to 60?days after deposition – 98.6% of the loaded deposits and 85.3% for natural deposits. Under outdoor conditions in Study 2, both loaded and natural deposits were affected by environmental exposure. Latent fingermarks were successfully developed up to 14?days after deposition on the outdoor feathers, with some occasional recovery after 21?days. The visible feathers recorded 34.7% (loaded) and 16.4% (natural) successful developments (Grade 1–4), whereas the hidden feathers recorded 46.7% (loaded) and 22.2% (natural) successful developments, suggesting that protection from the environment helps to preserve latent fingermarks on the surface of a feather. Environmental exposure accelerated the deterioration of ridge detail and the number of successful developments.  相似文献

This paper summarizes the current status of the ability of tribal law enforcement officers to enforce state law in all states that have Indian country – defined in 18 U.S.C. § 1151 as any Indian reservation, dependent Indian communities, or Indian allotments – within their borders. It is important to understand the current status of those officers as their agencies look to improve public safety in their nations. First, for context, we provide a brief background on tribes and tribal law enforcement. Then, we present a summary of the legal jurisdictional challenges faced by tribal law enforcement. Finally, we analyze the current status of tribal law enforcement officers in each state and conclude with a summary and concluding remarks.  相似文献
