ABSTRACT

Do framing strategies that are effective at encouraging pro-social behavior, such as participation in human rights campaigns, also mobilize support for violence within the same subjects? We use an experimental research design to examine individuals’ reactions to personal, humanizing narratives about past victimization. Participants are randomly assigned to one of eight treatment groups, which variously highlighted the humanity of the subject, the intensity of the past violence, and/or an evocative photograph of the subject that underscores her loss and vulnerability. We expect narratives that emphasize the subject’s humanity will encourage the audience to see the subject as innocent and as a victim, but also to feel angry about her experience. As a result, individuals will be more likely to defend the subject’s human rights, and to condone her use of retributive violence. We find that humanizing narratives lead respondents to simultaneously support a human rights appeal on the subject’s behalf and her use of retributive violence. Perceiving the subject in the narrative as innocent or as a victim mediates these effects, but anger often does not.  相似文献

This study developed a composite machine learning algorithm for attribution of materials of forensic interest (like ammonium nitrate) to original sources. k-nearest neighbor and random forest models were used for source elimination and classification, respectively, in a two-step, composite algorithm based on particle color, size/shape, and trace element concentration features. Novel approaches for simulation to supplement within-source reference features based on empirically measured multi-lot analyses, an improved hold-one-lot-out method for cross-validation, an assessment of the likelihood of the presence of a reference sample, fusion of the source probabilities from the respective classification models, and the calculation of metrics for assessing ensemble sourcing performance are described. Excellent sourcing predictions were obtained; the sourcing algorithm identified the correct source as the top choice 89% of the time, and the correct source was identified to be an average of 2.7 times more likely than the most likely incorrect source.  相似文献

Supreme Court confirmation hearings have been famously called a “vapid and hollow charade” by Elena Kagan. Indeed, perceptions of nominees’ refusal to answer questions about pending cases, prominent political issues, or give any hint of their ideological leanings have become a cornerstone of the modern confirmation process. We investigate the extent to which this reticence to speak of their ideological views, or candor, influences how individuals evaluate the nominee. To this end, we present the results of a survey experiment which examines how support for a hypothetical Supreme Court nominee is affected by information, especially when a nominee is presented to be very forthright or very reticent in answering ideological questions during the confirmation hearings. We find that while partisan compatibility with the president is the main determinant of support for a nominee, nominees who refuse to answer ideological questions can bolster support from respondents who would not support them on partisan grounds. We supplement these findings with observational state-level support data from real nominees over the last 40 years.  相似文献

Contract incentives are designed to motivate contractor performance and to provide public managers with a powerful tool to achieve contract accountability. Our knowledge of contract incentives is rooted in contract design, yet as we move beyond contract specification and further into the contract lifecycle, we know little about why and how managers implement incentives. This study assesses public managers’ use of contract incentives in practice and advances theory development. A typology of contract incentives is constructed to capture a comprehensive range of formal and informal incentives, and the factors that influence managerial use of incentives are identified. The findings shed light on the complexities of maintaining accountability in third‐party governance structures and the management techniques aimed at improving the performance of public agencies.  相似文献
