The differentiation of toners used in photocopy processes by infrared spectroscopy

Toners (inks) used in plain paper photocopying machines may be discriminated by infrared spectroscopy using small samples of solid toner removed from the paper surface.     

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.     

Exploring the relationships of women's sexual assault disclosure, social reactions, and problem drinking

The goal of this exploratory study was to examine correlates of sexual assault disclosure and social reactions in female victims with and without drinking problems. An ethnically diverse sample of sexual assault survivors was recruited from college, community, and mental health agencies. Ethnic minority women were less likely to disclose assault, and women with a greater number of traumatic life events disclosed assault more often. Although there were no differences in disclosure likelihood by drinking status; of those disclosing, problem drinkers told more support sources and received more negative and positive social reactions than nonproblem drinkers. Correlates of receiving negative social reactions were similar for normal and problem drinkers; however, negative social reactions to assault disclosure were related to more problem drinking for women with less frequent social interaction. Implications for future research and possible support interventions with problem-drinking victims are provided.     

The Problem of Social Order: What Should We Count as Law?

In these two fine contributions to the relatively small body of empirically‐grounded theoretical accounts of law, Fred Schauer and Richard McAdams focus on the two key elements of any legal system: the coordination of conduct that individuals have an incentive to engage in if they believe others will also, and the coercive force that is needed to deter conduct when coordination incentives are absent or insufficient. Both contributions deepen our understanding of the dynamics of coordination and coercion. But both also focus primarily on the concept of law as a set of rules generated and enforced exclusively by government. In this comment, drawing on recent work with Barry Weingast, I emphasize the importance of extending the scope of analysis to include settings in which governments are missing or weak and where legal order has not yet been achieved or stabilized—the challenge that faces many poor and developing countries around the world and the challenge that today's advanced legal regimes overcame historically. In our account, coordination and coercion are not substitute mechanisms, but are deeply linked: prior to the establishment of wealthy stable governments (and perhaps even in the presence of such governments), coercive penalties are delivered only if the decentralized application of punishment by ordinary individuals is successfully coordinated and incentivized.
