This study tested the extent to which coached participants can simulate the neural responses of participants with posttraumatic stress disorder (PTSD) when they are presented with signals of fear. Functional magnetic resonance imaging (fMRI) was used to study blood oxygenation level-dependent signal during the presentations of fearful and neutral faces under both conscious and nonconscious (masked) conditions. Participants comprised 12 patients with PTSD and 12 trauma-exposed controls who were instructed to simulate PTSD. During conscious fear processing, simulators showed greater activation in the left amygdala and medial prefrontal cortex (MPFC) than PTSD participants. By contrast, during nonconscious processing, PTSD participants had greater MPFC activation than simulators. These findings suggest that coached simulators produce a profile of ‘over-responding’ to fear when controlled conscious processing is possible, but are not able to simulate the exaggerated medial prefrontal responses observed in PTSD participants under conditions of nonconscious processing.  相似文献

This paper provides one of the first empirical analyses of the local voter initiative. Using a unique and comprehensive dataset from California, it analyzes determinants of local initiatives and effects of these measures on municipal finances. Results indicate that initiatives occur more frequently in large and diverse jurisdictions with more recent movers, voters unaffiliated with a major political party, and public employees. Effects of city size are partly offset by district- or ward-level elections. Contrary to previous research on statewide initiatives, this study detects a positive and weakly significant relationship between local initiative use and own-source revenues per capita and no association between initiatives and the proportion of funds raised from fees. These divergent findings may reflect distinctive features of the local context, including greater latitude for political bargaining and the centrality of land use, as well as potential constraining effects of statewide initiatives in California.  相似文献

Purpose. The goal of the present study was to investigate the effects of personality variables, interrogation techniques and the plausibility level of an alleged transgression on the experimental elicitation of false confessions. Methods. Two hundred and nineteen undergraduate students assessed on measures of compliance, self‐esteem, locus of control and interrogative suggestibility participated in the Kassin and Kiechel (1996) paradigm. Experimental manipulations included minimization and maximization interrogation techniques and high and low plausibility of the alleged typing mistake to examine rates of false confession and internalization. Results. The overall false confession and internalization rates across all conditions were 43 and 10%, respectively. An increased likelihood of false confession behaviour was associated with higher Shift scores on the Gudjonsson Suggestibility Scale, the use of minimization interrogation techniques and an increase in the plausibility of the allegation. Females were more likely to falsely confess than males in the high plausibility condition, whereas Caucasian and Asian participants were equally likely to falsely confess. Personality variables, such as compliance, most influenced the behaviour of males and Asians. Conclusions. The results of this study offer insight into false confession behaviour, suggesting that individuals who have a tendency to change their responses in the face of negative feedback may be more prone to false confession behaviour. The findings also serve to highlight the dangers of using minimization interrogation techniques and elucidate the limited generalizability of the paradigm to situations in which the alleged transgression is less plausible.  相似文献

Perceptions of children's credibility were studied in two experiments wherein participants watched a videotape of a 4- to 5- or a 6- to 7-year old child report details of a play session that had been experienced once (single-event) or was the last in a series of four similar play sessions (repeat-event). The child's report was classified as high or low accurate. In Experiments 1 and 2, reports of repeat-event children were judged to be less believable on several measures. In Experiment 1, younger children were viewed as less credible than older children. In both experiments, neither undergraduates nor community members correctly discriminated between high- and low-accurate reports. Content analysis in Study 3 revealed the relationship between age and event frequency and children's credibility ratings was mediated by the internal consistency of children's reports. Recent research on children's reports of instances of repeated events has identified several challenges facing children who report repeated abuse. These data bring to light another potential difficulty for these children.  相似文献

Exposure of forensic evidence to either hydrogen chloride or chlorine can result in acidification to such an extent that enhancement of fingermarks with ninhydrin or cyanoacrylate is inhibited. Under these circumstances, pretreatment of samples with volatile bases such as triethylamine or ethanolamine prior to using these enhancement techniques can lead to successful visualization of fingermarks. Alternatively, physical enhancement techniques such as powder dusting or small particle reagent can be used on acidified non-porous substrates, although the former technique is subject to increased background under such conditions.  相似文献

Three studies were conducted to test the role of the dehumanization of refugees (through claims that they are immoral) in determining emotional reactions to refugees, attitudes toward refugees, and attitudes toward current refugee policy in Canada. We also examined determinants of such perceptions. In Studies 1 and 2, correlational analyses and structural equation modeling were utilized. In both studies, it was demonstrated that individuals who are higher in social dominance orientation are especially likely to dehumanize refugees, and this dehumanization leads to greater contempt and lack of admiration for refugees, resulting in less favorable attitudes toward the group and toward the nation’s current refugee policy. Study 3 was an experiment in which we examined the effects of information presented about refugees on emotions and attitudes. Results demonstrated that dehumanizing media depictions of refugees as violating appropriate procedures and trying to cheat the system cause greater contempt and lack of admiration for refugees in general, which in turn lead to less favorable attitudes toward the group and less support for the current refugee policy. Results are discussed in terms of the functions that dehumanization may serve, and potential strategies for counteracting such effects. Preparation of this article was supported by a Social Sciences and Humanities Research Council of Canada grant to the first author. Portions of this research were presented at the 2005 EAESP Small Group Meeting on Social Justice and Intergroup Conflict, Lisbon, Portugal, and at the 2005 Meeting of the European Association of Experimental Social Psychology, Wurzburg, Germany  相似文献

The economic restructuring in China over the past decade has resulted in displacement of millions of workers who had been employed in the state sector. This has posed tremendous challenges economically, socially, politically, and culturally. For several years, Chinese policies attempted to cushion the shock by requiring state-owned enterprises to provide living allowances and reemployment services to workers who had been displaced. There have been few empirical studies that have tracked the experiences of these displaced or xiagang workers. This study uses survey data from two large industrial cities covering the period 1998–2000 to analyze the labor market situation of over 2,000 workers 2 years after they had been observed as displaced and unemployed. The findings point to the high rates of labor force withdrawal and a low proportion who find another wage job in the formal sector. It also documents the large number of workers who find work in the informal sector which seems to act as an important safety net. Not surprisingly, education is an important determinant of post-layoff labor market outcomes. Active labor market interventions do not seem to make a substantial difference although there is some evidence from the duration analysis that training does help workers find employment more quickly than they would have otherwise.

The Australian state of New South Wales (NSW) was the first jurisdiction to fully deregulate law firm structure and allow alternative business structures in the legal profession. At the same time it also introduced an innovation in regulation of the legal profession, requiring that incorporated legal practices implement ‘appropriate management systems’ for ensuring the provision of legal services in compliance with professional ethical obligations. This paper presents a preliminary empirical evaluation of the impact of this attempt at ‘management‐based regulation’. We find that the NSW requirement that firms self‐assess their ethics management leads to a large and statistically significant drop in complaints. The (self‐assessed) level of implementation of ethics management infrastructure, however, does not make any difference. The relevance of these findings to debates about deprofessionalization, managerialism, and commercialism in the legal profession is discussed, and the NSW approach is distinguished from the more heavy‐handed English legal aid approach to regulating law firm quality management.  相似文献

Africa’s population is growing faster than its locally produced food supply. While some regions of the world wallow in production surpluses, neither the Green Revolution nor other production boosting strategies have sunk deep roots in Africa. As a result, there is an increasing food production shortfall and an ever larger dependence on outside food aid. In response, international development agencies are developing new strategies for tackling the seemingly intractable problems of African agriculture. One of these strategies is called the farming systems research and extension approach. This approach starts with the understanding that “African agriculture has probably been less affected by technology change in the past twenty years than agriculture on any other continent” (A.I.D., 1985). It continues by developing technical interventions which are advantageous within particular “recommendation domains” defined by both social and environmental conditions.  相似文献
