This paper presents a number of case studies involving pre- and midtrial prejudice in criminal and civil litigation. The cases reveal deficiencies in the way that prejudicial publicity has been conceptualized and operationalized in many simulation experiments. The studies reveal that potential juror prejudices that concern lawyers and judges involve more than just main effects of mass media. Pre- and midtrial prejudice also involves more general prejudices, gossip and rumor, the assertion of community normative values about justice, and conformity pressures. Four categories of prejudice recognized in American law are described and labeled: interest, specific, generic, and conformity prejudice. The case studies also reveal interesting dynamics involving minimization and inconsistency in jurors' self-reports of attitudes which contradict a commonly held judicial view that superficial questioning is sufficient to uncover prejudice. Despite identifying deficiencies in the simulation literature, the paper concludes that experimental research is necessary to provide answers to causal questions that case studies and field research cannot ordinarily provide. 相似文献

This study examined the interaction between testimonial consistency and eyewitness confidence on mock-jurors' judgments of probability that the defendant committed the crime and verdicts. In a 2 (testimonial consistency) × 2 (confidence) between-groups design, 130 mock-jurors listened to an audio-taped trial of a person charged with armed robbery. Manipulations were contained in the prosecution witness's responses to detailed questioning by prosecution and defense attorneys. Although consistency is considered to be a key marker of accuracy, its impact on judgments was weak and nonsignificant. Witness confidence had a strong influence on judgments, whether testimony was consistent or inconsistent. We suggested that witness confidence may be more likely to emerge as a dominant influence on juror judgments when the testimony is wide ranging rather than relatively brief and concerned only with a specific issue (e.g., identification confidence). 相似文献

Amphetamine samples were analysed by gas chromatography-mass spectrometry (GC-MS), and the peak areas of 33 target compounds were transformed by applying various pretreatment techniques. The objective was to optimise the ability of a number of distance metrics to establish links between samples of amphetamine originating from the same batch (henceforth referred to as linked distances). Furthermore, partial least squares discriminant analysis (PLS-DA) was used to evaluate the effects of various pretreatment methods on separation of amphetamine batches synthesised by the Leuckart reaction, reductive amination of benzyl methyl ketone, and the nitrostyrene route. The most efficient way to pretreat GC-MS data varied for the different distance metrics, although best results were obtained when data were normalised to the sum of peak areas, and either the fourth root or a logarithm was applied to the normalised data. When pretreating normalised data by fourth root transformation, Pearson correlation was the distance metric that was most successful at finding linked samples. Normalisation and the use of fourth root also represented the best method of pretreating data when employing PLS-DA to separate samples synthesised by different routes. To achieve a faster and more user-friendly procedure for evaluating chromatograms, experiments were performed in which the number of target compounds used to compare samples was reduced. The effect of each compound that was removed was studied by applying PLS-DA and by using Pearson correlation to calculate linked distances as well as unlinked distances (between samples from different batches of amphetamine). Considering both links between samples from the same batch and separation of samples synthesised by different routes, the best results were obtained with the data set comprising 26 compounds. Finally, it was found that the profiling method developed in this work was superior to an existing technique with respect to separating linked and unlinked distances. 相似文献

Individuals with schizophrenia are at risk of developing HIV and are known to experience barriers to optimal medical care. Our goal was to determine, among a cohort of HIV clinicians, whether or not the diagnosis of schizophrenia affected the clinical decision to offer highly active antiretroviral therapy (HAART) to AIDS patients. This is a cross-sectional study of a random, national sample of HIV experts drawn from the membership of the American Academy of HIV Medicine. Participants were mailed a self-administered questionnaire with a case vignette of a new onset AIDS patient and were specifically asked whether or not they would recommend HAART treatment. Vignettes were randomly assigned to include a diagnosis of schizophrenia or not. We located 649 clinicians (93%); 347 responded (53.4%). Responders and non-responders did not differ in demographics or work characteristics. Recommendation of antiretroviral treatment did not differ between those who received a case vignette with schizophrenia versus those who did not(95.8% vs. 96.6%, p=0.69). Compared to those who received a case vignette without schizophrenia, those who received vignettes with schizophrenia were more likely to avoid prescribing efavirenz, a medication with known neuropsychiatric side effects(17.7% vs. 45.5%, p < 0.01), more likely to agree to be helped by a specialist(34.5% vs. 12.9%, p < 0.01), and more likely to recommend directly observed therapy (20% vs.10%, p = 0.01). HIV clinicians recognize the importance of recommending HAART treatment to individuals with schizophrenia and AIDS and avoid using antiretroviral medication with known neuropsychiatric side effects. 相似文献

According to many theoretical accounts of the vote choice, distal determinants (e.g., party identification) influence proximal
determinants (e.g., perceptions of candidates), which in turn shape candidate preferences. Yet almost no research on voting
has formally tested such mediational hypotheses. Using national survey data collected between February and September of 2004,
this paper begins by illustrating how to conduct such investigations. We explored whether public approval of President Bush’s
handling of a series of specific national problems (e.g., the Iraq war) influenced overall assessments of his job performance
and evaluations of his likely future performance versus John Kerry’s, which in turn shaped vote choices. The results are consistent
with the claim of mediation and shed additional light on the impact of various issues on the 2004 election outcome. We also
tested what we term the “dosage hypothesis,” derived from news media priming theory, which posits that changes in the amount
of media coverage of an issue during the course of a campaign should precipitate changes in the weight citizens place on that
issue when evaluating the president’s overall job performance, particularly among citizens most exposed to the news. Surprisingly,
this analysis did not yield consistent support for the venerable dosage hypothesis, suggesting that the conditions under which
priming occurs should be specified much more precisely in future work.

The unusual appearance of crystalline fat structures was observed during the postmortem examination of a motor vehicle accident victim. The crystal structures were characterized using Fourier transform infrared spectroscopy and x-ray diffractometry. The structures were found to be made of triacylglycerols, a dominant lipid structure found in human adipose tissue, capable of forming various polymorphic structures. The morphology of the crystalline material was found using both techniques to be predominantly the beta' form of triacylglycerols. The accelerated growth of such triacylglycerol morphology has been observed as a result of shear stresses in other studies involving edible fats. As a result of the findings of this study, it is proposed that increased shear forces may be responsible for the formation of the unusual fat structure found in the victim. An understanding of the effect of forces on the structure of body fat in high-impact collisions can potentially assist in verifying a high-velocity impact. 相似文献

Our (2014) model for the regulation of cognitive enhancement devices (CEDs) received a great deal of interest from those involved in European device regulation and from academic commentators. Further, since the publication of our recommendations, the number of manufacturers of brain stimulation devices for non-medical purposes has increased, underscoring the need for a regulatory response. In this paper, we clarify aspects of our original proposal and address additional regulatory issues beyond our original focus on the sale of devices. We begin with theoretical points pertaining to the definition of a CED and the distinction between treatment and enhancement. We then respond to practical challenges raised by the prospect of implementing our regulatory framework. Next, we address some wider societal considerations relating to users and other stakeholders. Finally, we revisit the broader regulatory context within which the various discussions are situated. 相似文献

Nelson Mandela is highly regarded as an example of excellent leadership. Yet little has been done in communication studies to describe his leadership communication. Significantly, little has been done to locate and to theorise about his leadership style in relation to the African moral philosophy of ubuntu. the article presents an appreciative thematic analysis of how Mandela’s leadership communication practices were eulogised in tributes written in his memory in selected South African newspapers. An innovative method of appreciative thematic enquiry is used to arrive at three key themes of praise for the leadership of Mandela. Lessons for leadership are drawn out and highlighted. 相似文献
