Why Are the Poor More Vulnerable to Bribery in Africa? The Institutional Effects of Services

Whereas most studies find the poor in Africa to be more vulnerable to bribery because of their lower socio-economic status, this paper proposes institutional differences as an alternative explanation. Because poor people are unable to afford privately provided services, they must use public services. In relying on the state more often, the poor become more vulnerable to bribery. Analyses of Afrobarometer data show that the poor are not more likely to pay bribes for state monopolised services. The poor’s disproportionate vulnerability to bribery for choice services is a function of their greater likelihood to have contact with the state.     

Being Underway,Not in Delay,on Climate Change-Related Disclosure

Confusion among companies over what is adequate in environmental disclosure, in general, sets an unfortunate stage for contemplating the newer matter of climate change-related disclosure. Companies waiting for new legislative and regulatory outcomes before contending with climate change disclosure, however, are in exposed and inadvisable delay on the matter. Existing regulations and standards pertain and instruct, if indirectly, on what is to be disclosed and accrued, and when. Their requirements, the possibility of enforcement actions, and recent evidence of costly consequences to former executives from improper environmental financial disclosure reinforce corporate management's need for disclosure diligence, including on climate change. The future is here.     

Experimental Methodology in Political Science

Experiments offer a useful methodological tool to examine issuesof importance to political scientists. The historical and culturaldifferences between experiments in behavioral economics andsocial psychology are discussed. Issues of central concern toexperimentalists are covered, including impact versus control,mundane versus experimental realism, internal versus externalvalidity, deception, and laboratory versus field experiments.Advantages and disadvantages of experimentation are summarized.     

Evaluating the Comprehensibility of Jury Instructions: A Method and an Example

Methodological problems in jury simulation research involve issues of sampling, choice of stimulus materials, appropriate unit of analysis, appropriate dependent variable, corroborative data, and problems of role playing. Despite these issues, comprehension of jury instructions may be suitable for examination by jury simulation techniques--if certain of these methodological concerns can be satisfied. In a series of 5 experiments using typical Canadian legal instructions on criminal conspiracy and the coconspirator exception to the hearsay rule, this study attempted to validate a simple and inexpensive technique for testing the incomprehensibility of a given set of jury instructions by requiring participants to apply those legal instructions to a set of facts. The results demonstrate the utility of an application test, and suggest that for assessing the comprehensibility of jury instructions, it may be acceptable to use undergraduate students as participants, to use individual participants without group deliberation, and to employ written stimulus materials.     

Analysis of forensic SNPs in the canine mtDNA HV1 mutational hotspot region

A 60 bp sequence variation hotspot in the canine mitochondrial DNA hypervariable region 1 was evaluated for its use in forensic investigations. Nineteen haplotypes containing 18 single nucleotide polymorphisms were observed among laboratory-generated and GenBank-derived domestic dog sequences representing five regional localities in the U.S. Samples from the different localities were highly variable with the levels of intra-population variability being similar among the populations studied. AMOVA further confirmed that there was no significant genetic structuring of the populations. Assays using these haplotypes were robust, canid specific and portend a rapid method for correctly excluding individual dogs as noncontributors of forensic evidence. Species-specificity of the primers was confirmed by means of in-tube polymerase chain reaction of human and cat DNA and in-silico assessment of the genomes of several animal species. Breed-specific fragments were not detected among the common haplotypes but there is evidence that this assay may be capable of differentiating domestic dog, wolf, and coyote sequences.     

It depends whose data are being shared: considerations for genomic data sharing policies

There is an urgent need for consistent data sharing policies that promote the advancement of science while respecting the values and interests of those providing their genetic data for research. Responding to the article of Jalayne J. Arias, Genevieve Pham-Kanter, and Eric G. Campbell, ‘The Growth and Gaps of Genetic Data Sharing Policies in the United States’, this commentary further explores the challenges of human subjects’ protection in existing data sharing policies. We will elaborate on the need for data sharing policies to accommodate variation in individual and group preferences around data sharing and privacy concerns by comparing our previously published data on patients’ and parents’ consent to data sharing and attitudes about privacy to data from focus groups with HIV-positive, underserved individuals who were asked about their willingness to participate in genetic research and share their data broadly. These studies support the observation of Arias, Pham-Kanter, and Campbell that researchers, and funding agencies will need to balance the privacy interests of groups as well as individuals in future genomic data sharing policies.
