Fourier-transform infrared spectroscopy (FTIR), discriminate analysis, X-ray fluorescence spectrometry (XRF), and stereoscopic microscopy were used to separate black coral forensic evidence items from similarly appearing items manufactured from plastics, bovid keratin, and mangrove wood. In addition, novel observations were made of bromine and iodine relationships in black coral that have not been previously reported.  相似文献

Most estimates of the incumbency advantage and the electoral benefits of previous officeholding experience do not account for strategic entry by high‐quality challengers. We address this issue by using term limits as an instrument for challenger quality. Studying US state legislatures, we find strong evidence of strategic behavior by experienced challengers. However, we also find that such behavior does not appear to significantly bias the estimated effect of challenger experience or the estimated incumbency advantage. More tentatively, using our estimates, we find that 30–40% of the incumbency advantage in state legislative races is the result of “scaring off” experienced challengers.  相似文献

This paper explores Senate policy-making toward Israel from 1993–2002. Previous scholarship suggests that congressional policymaking toward Israel is heavily influenced by the ethnic and religious identification of both legislators and their constituents, not simply by legislators' abstract perceptions of the national interest. Other literature de-emphasizes the likelihood that constituent interests will affect Congressional foreign policy making. We test for an impact of both elite and constituent characteristics on Congressional support for Israel, using sponsorship–cosponsorship decisions in the 103rd–107th Congresses. Israel's strongest supporters in this period are shown to be Jewish, conservative, Republican, and evangelical senators. Notably, elite characteristics (partisanship, ideology, and religion) matter more than constituency factors, with the exception of the Jewish population in senators' home states. While Jewish and conservative senators have long been vocal supporters of Israel, evangelical and Republican senators have not historically taken such a strong pro-Israel stance; hence they are relatively new additions to the active pro-Israel coalition. Thus the pro-Israel coalition shows both continuity and change as it has broadened to include new partners. However, we suggest that this coalition is not necessarily stable and may undergo further evolution in the future.  相似文献

Using a two stage rent-seeking framework, we present a simple model of strategic entry/terrorism deterrence and test the model using laboratory experiments. Our contest success function highlights the potential for strategic spillovers. The theory illustrates that, relative to a cooperative outcome, negative externalities lead to over-spending on deterrence and positive externalities lead to under-spending on deterrence. Our experimental results are broadly consistent; subjects in the negative externality treatment had higher expenditures. In contrast to theoretical predictions, participation decisions, while primarily driven by the probability of winning a contest, were influenced by a subject’s ability to participate in multiple contests.  相似文献

Sociodemographic variables may have important implications for understanding the role of global and discrete-level emotion regulation ability in the prediction of elementary school children’s peer victimization. We tested this hypothesis in a sample of 109 elementary school children from economically and racially diverse backgrounds. There was a positive relation between sadness regulation and overt victimization for children in early elementary grades, but not for children in later grades. In addition, there was a positive relation between sadness regulation and relational victimization for boys and a negative association between the two variables for girls. Girls were rated higher than boys on global emotion regulation ability. In addition, economically disadvantaged children reported more relational victimization than their more affluent peers. Affluent children also received higher ratings on global emotion regulation as well as sadness regulation. Anger regulation was also positively associated with overt victimization.  相似文献

Crime-Reduction Effects of Open-street CCTV: Conditionality Considerations   总被引:2,自引:0,他引:2  
This study addresses the conditional nature of the effectiveness of open-street CCTV (closed circuit television) by examining the differences in the effects (1) between daytime and nighttime crime, (2) between weekday and weekend crime, (3) across specific-crime offenses, and (4) depending on CCTV site characteristics, including location type (e.g. downtown, business district, school/university, or residential area) and the site’s base rate of crime. This study used HLM (hierarchical linear modeling) with 84 repeated measures across 34 camera locations in Cincinnati, Ohio, while also accounting for overlapping camera areas. Overall, the findings provided minimal evidence of the effectiveness of CCTV in reducing crime, though some types of crime were reduced in residential areas especially, and effectiveness was clearly interdependent with an area’s base rate of crime. Finally, WDQ analyses showed that diffusion of benefits occurred much more often than displacement in cases where there was a crime reduction, post-CCTV.  相似文献

Children living on ‘the edge-of-care’ are typically known to local safeguarding authorities and are considered likely to face risks to their safety. Many are subject to a child protection plan and/or involved in ‘pre-proceedings’ processes. A growing number of their parents face (un)diagnosed mental health difficulties as well as economic and social precarity. This article draws on a mixed methods evaluation of a pilot service in the East of England offering a therapeutically led attachment-based intervention for families. The service cross-cuts health and social care, allowing psychologists and psychotherapists to work alongside social workers and other practitioners. The evaluation examined psychological and safeguarding outcomes and explored practitioner perspectives. A key outcome was that 85.4% of families were enabled to remain, or reunite with their child, compared with an estimated 50% of ‘edge-of-care’ cases nationally. This supports the need for similarly oriented interventions that could help lower the incidence of child removals.  相似文献

The first and second articles in this 3-part series discussed systematic issues related to multiple standardization problems and their compounding impact on the state and federal disability systems. In addition, the lack of standardization negatively influencing the behavioral health (BH) training and treatment processes may have the potential to cause harm not only to the individual receiving professional care but also to the clinician providing the treatment. In the final article of the series, I make recommendations for systemic changes for the field as well as for potentially revising previous models toward moving the Behavioral Health treatment and disability systems into more of a biopsychosocial approach. However, conclusions emphasize that successful implementation of recommendations and models require the involvement of all of the stakeholders in promoting better outcomes and in facilitating individuals; return to the workplace.  相似文献
