Impact of hypnotic testimony on the jury

In the past decade, the forensic use of hypnosis to enhance the memories of victims, witnesses, and defendants has sharply increased. A great deal of controversy surrounds this issue. Some commentators argue that testimony derived from hypnosis should not be allowed as evidence because of its inherent unreliability and the unduly powerful impact it may have on a jury. In the present research, we used a jury simulation technique to study the impact that a hypnotically refreshed witness has upon jurors' decision making. A major finding is that jurors view hypnotic testimony with a certain amount of skepticism. In some respects, its impact is comparable to that of testimony based on delayed recall, and rarely does it have the impact of testimony from an immediate report. In addition, jurors' judgments about hypnotically refreshed testimony affected the way they evaluated other evidence at trial: Jurors who learned that a prosecution witness had been hypnotized were less believing ofother prosecution witnesses than were jurors not exposed to hypnotic testimony. The forensic application of these findings is discussed.This research was supported by a grant from the National Science Foundation, Law and Social Sciences Program.

From democratic socialism to neoliberalism: the metamorphoses of the people's national party in Jamaica

Why are leftist parties in government abandoning their state-led, redistributive economic development models in favor of market-determined neoliberal ones? Conventional explanations emphasize conditionality of international financial institutiosn. This argument, though, fails to account for differences in economic policy choices across countries or within a country over time. Analyzing the social democratic People's National Party of Jamaica during two periods when it accepted IMF-mandated neoliberal economic reform measures (1977–80 and 1989-present), an alternative approach is presented to illuminate why and how leftist governments switch economic policy programs. The two time periods show that IMF conditionality might be a necessary motivation for the adoption of neoliberal economic measures, but it is not sufficient motivation. I argue that the actual policies the PNP governments employed reflect changes in the relative influence of competing factions within the party. This approach, focusing on domestic actors rather than international ones to account for economic policy shifts, highlights the ways in which politicians can manipulate institutional rules to change the relative weight of different factions within the party to gain support for policy decisions that contradict the party's traditional social democratic ideology.     

Cognitive Heterogeneity and Economic Voting: A Comparative Analysis of Four Democratic Electorates

This article examines the cognitive foundations of economic voting in four diverse democratic electorates: Canada, Hungary, Mexico, and Taiwan. We present a theory of heterogeneous attribution, where an individual's level of political sophistication conditions his or her ability to attribute responsibility for economic conditions to governmental actors. In contrast to previous literature, we argue that higher, not lower, levels of political sophistication prompt citizens to "vote their pocketbook." Using data from surveys done in conjunction with recent elections in all of these countries, we find that more politically sophisticated respondents are more likely to make use of pocketbook evaluations in their decisions to support or oppose the incumbent government. These findings both present a significant challenge to the conventional wisdom on political sophistication and economic voting and shed light on the necessary cognitive preconditions for democratic accountability.     

Characterization of the Caucasian haplogroups present in the SWGDAM forensic mtDNA dataset for 1771 human control region sequences. Scientific Working Group on DNA Analysis Methods

Currently, the Scientific Working Group on DNA Analysis Methods (SWGDAM) mtDNA dataset is used to infer the relative rarity of mtDNA profiles (i.e., haplotypes) obtained from evidence samples and for identification of missing persons. The Caucasian haplogroup patterns in this forensic dataset have been characterized using phylogenetic methods. The assessment reveals that the dataset is relevant and representative of U.S. and European Caucasians. The comparisons carried out were both the observation of variable sites within the control region (CR) and the selection of a subset of these sites, which partition the variation within human mtDNA control region sequences into clusters (i.e., haplogroups). The aligned sequence matrix was analyzed to determine both single nucleotide polymorphisms (SNPs) in a phylogenetic context, as well as to check and standardize haplogroup designations with a focus on determining the characters that define these groups. To evaluate the dataset for forensic utility, the haplogroup identifications and frequencies were compared with those reported from other published studies.     

Surface Curvature of Pelvic Joints from Three Laser Scanners: Separating Anatomy from Measurement Error

Recent studies have reported that quantifying symphyseal and auricular surface curvature changes on 3D models acquired by laser scanners has a potential for age estimation. However, no tests have been carried out to evaluate the repeatability of the results between different laser scanners. 3D models of the two pelvic joints were generated using three laser scanners (Custom, Faro, and Minolta). The surface curvature, the surface area, and the distance between co‐registered meshes were investigated. Close results were found for surface areas (differences between 0.3% and 2.4%) and for distance deviations (average <20 μm, SD <200 μm). The curvature values were found to be systematically biased between different laser scanners, but still showing similar trends with increasing phases/scores. Applying a smoothing factor to the 3D models, it was possible to separate anatomy from the measurement error of each instrument, so that similar curvature values could be obtained (p < 0.05) independent of the specific laser scanner.     

Pigeons and people: mortal enemies or lifelong companions? A case study on staff perceptions of the pigeons on the University of South Africa,Muckleneuk campus

Pigeons have been a part of our lives for as long as we can remember. Some people view them with joy, others disdain. Regardless of the perception, control measures are often implemented against the birds in a bid to reduce their presence in urban environments without considering the views of members of the public in the process. Complaints about pigeon activity are, typically, given more attention than praise for these birds. However, people who are pro‐pigeons are often not provided with the forum to express their views of the birds. This study explored the perceptions of staff with regard to the pigeons inhabiting the University of South Africa's Muckleneuk campus. Two hundred and forty‐six participants provided their opinions on the pigeons, their related activities and the perceived impact on staff on the campus. Recognising that both people and urban wildlife play a role of cause‐and‐effect in human–wildlife conflicts can contribute to understanding peoples' relationships and perceptions of animals which transgress the boundaries between urbanisation and nature. By considering peoples' perceptions, attitudes and behaviours towards urban wildlife, management strategies can be significantly informed in the process of mitigating conflict. The study has shown that the negative perception of pigeons, which was assumed to be the position of all the people affected by the pigeons at the University of South Arica's Muckleneuk campus, is in fact incorrect. Participants would rather encourage the nesting and breeding activities of the pigeons on campus, as they felt that the human–pigeon interactions and the viewing of squabs in nests contributed positively to their work environment. Pigeon control strategies should therefore not solely be on the biological aspect of a perceived pigeon problem, but should also include the human association. Copyright © 2016 John Wiley & Sons, Ltd.
