Abstract: Recent neuroimaging studies investigating the neural correlates of deception among healthy people, have raised the possibility that such methods may eventually be applied during legal proceedings. Were this so, who would volunteer to be scanned? We report a “natural experiment” casting some light upon this question. Following broadcast of a television series describing our team’s investigative neuroimaging of deception in 2007, we received unsolicited (public) correspondence for 12 months. Using a customized template to examine this material, three independent assessors unanimously rated 30 of an initial 56 communications as unequivocally constituting requests for a “scan” (to demonstrate their author’s “innocence”). Compared with the rest, these index communications were more likely to originate from incarcerated males, who were also more likely to engage in further correspondence. Hence, in conclusion, if neuroimaging were to become an acceptable means of demonstrating innocence then incarcerated males may well constitute those volunteering for such investigation. 相似文献

Measuring Attitudes toward the United States Supreme Court 总被引:2,自引:1,他引:2

It is conventional in research on the legitimacy of the U.S. Supreme Court to rely on a survey question asking about confidence in the leaders of the Court to indicate something about the esteem with which that institution is regarded by the American people. The purpose of this article is to investigate the validity of this measure. Based on a nationally representative survey conducted in 2001, we compare confidence with several different measures of Court legitimacy. Our findings indicate that the confidence replies seem to reflect both short-term and long-term judgments about the Court, with the greater influence coming from satisfaction with how the Court is performing at the moment. We suggest a new set of indicators for measuring the legitimacy of the Court and offer some evidence on the structure of the variance in these items. 相似文献

Approximately 20% of adolescents develop depressive symptoms. Family, friends, and teachers are crucial sources of social support for adolescents, but it is unclear whether social support impacts adolescents directly (principle-effect model) or by moderating the effect of stress (stress-buffer model) and whether each source of social support remains meaningful when their influence is studied simultaneously. To help fill this gap, we followed 1452 Australian students (average age at enrollment?=?13.1, SD?=?0.5; range: 11–16 years; 51.9% female) for 5 years. Based on our findings, each source of support is negatively related to depressive symptoms one year later when studied independently but when combined, only family and teacher support predicted depressive symptoms. Family support in all grades and teacher support in grade 8 to 10 but not in grade 11 directly impacted adolescent depressive symptoms 1 year later. Family support in grades 8 and 11 also buffered against the negative impact of stress on depressive symptoms one year later. Based on the unexpected findings, the most important limitations seem to be that the used instruments do not allow for a separation of different groups of friends (e.g., classmates, same-gender peers, romantic partners), types of social support, and stress. In addition, the high, nonrandom attrition rate with adolescents reporting less social support, more stressful events, a higher frequency of depressive symptoms, and/or being of Torres Strait Islander or Aboriginal background limits the generalizability of our findings. Summarized, our findings demonstrate that adolescents facing stress might benefit more from family support compared to their peers without stressful life events and that friends may have a weaker presence in adolescent lives than expected. 相似文献

Some who have written about the logic of experimentation arguethat random assignment of subjects to treatment conditions isan essential attribute of an experiment. Others disagree. Ratherthan treating this as a matter of dueling definitions, we considerexperiments without randomization from a theoretical perspective.Our central contention here is that, for some research questions,theory dictates systematic (not random) assignment of respondentsto experimental conditions. Two such areas of inquiry are researchon political tolerance and on institutional legitimacy. Thisarticle gives cursory attention to the former body of work anddetailed attention to the latter, based on an experiment conductedin a survey in 2001 on the consequences of the American presidentialelection for institutional legitimacy. Because in both instancestheory requires nonrandom assignment, the problem becomes oneof identifying the costs of nonrandomization (threats to internalvalidity) and specifying analytical techniques that might amelioratethose costs. Consequently, we present results from a statisticalapproach that addresses the problem of nonrandomization. Themost important claim of this article is that theory ought tospecify research design, including experimental designs, andthat dogmatic attachment to one definition of experiment willnot serve the discipline of political science. 相似文献

Lily Montagu was involved in social work and religious ministry with the London Jewish community for over sixty years. This article considers the significance of her involvement in the girls' club movement and her efforts towards workplace reform. It argues that the specific circumstances of working-class Jewish girls in the early twentieth century enabled her to develop a comprehensive view of both industrial organisation and social work. Her approach was submerged as social work and trade unionism diverged along fault lines of gender, but continues to raise issues of relevance today. 相似文献
