Understanding Interaction Models: Improving Empirical Analyses

William Roberts Clark University of Michigan, Center for Political Studies, ISR 4202 Box 1248, 426 Thompson Street, Ann Arbor, MI 48106-1248 Matt Golder Florida State University, Department of Political Science, 531 Bellamy Building, Tallahassee, FL 32306-2230 e-mail: thomas.brambor{at}nyu.edu e-mail: wrclark{at}umich.edu e-mail: matt.golder{at}nyu.edu (corresponding author) Multiplicative interaction models are common in the quantitativepolitical science literature. This is so for good reason. Institutionalarguments frequently imply that the relationship between politicalinputs and outcomes varies depending on the institutional context.Models of strategic interaction typically produce conditionalhypotheses as well. Although conditional hypotheses are ubiquitousin political science and multiplicative interaction models havebeen found to capture their intuition quite well, a survey ofthe top three political science journals from 1998 to 2002 suggeststhat the execution of these models is often flawed and inferentialerrors are common. We believe that considerable progress inour understanding of the political world can occur if scholarsfollow the simple checklist of dos and don'ts for using multiplicativeinteraction models presented in this article. Only 10% of thearticles in our survey followed the checklist.     

The Effects of Prior Workplace Behavior on Subsequent Sexual Harassment Judgments

A dual processing model of sexual harassment judgments predicted that the behavior of a complainant in a prior case would influence evaluations in an unrelated subsequent case. In the first of two experimental scenarios depicting social-sexual conduct at work, the female complainant's conduct was manipulated to be aggressive, submissive, ambiguous, or neutral. Half of the participants were asked to reflect upon the first scenario after reading it and before answering responsibility questions. The other half simply reviewed the scenario and answered the questions. When the complainant acted aggressively, her behavior in the first scenario caused men who reflected on the fact pattern to find less evidence of harassment. Most interestingly, an aggressive complainant observed in the first scenario caused participants (especially women) to rate lower the likelihood that a neutral complainant in a second independent case was the victim of gender discrimination. Across cases, men found less evidence of harassment than did women.     

Restorative Sentencing: Exploring the Views of the Public

Within the past decade, restorative justice has emerged as a truly global phenomenon. Although retributive justice has dominated the penal landscape, more recently, restorative principles at sentencing have attracted increased attention. Restorative sentencing emphasizes the importance of compensation and reconciliation between victims and offenders and pays less attention to establishing proportionality between the seriousness of the offense and the severity of the sentence imposed. Although voluminous (and proliferating), the scholarly literature on restorative justice has to date neglected one critical issue: public opinion with respect to this justice paradigm. Public opinion researchers too, have generally overlooked this topic. The goal of this paper is to determine which elements of the new paradigm generate public approval, and which features are likely to encounter or provoke public opposition, drawing upon related international research published in English over the past 20 years (1982–2002). The review reveals widespread support for restorative sentencing options, such as community service, compensation, and restitution, particularly when applied to young offenders. However, it also seems clear that public support for these alternatives to punitive sentencing options declines as the seriousness of the offence increases, suggesting strong public adherence to the retributive principle of proportionality in sentencing.     

Lockbox Government: Segregated Funding Strategies and the Decline of Governmental Flexibility

Proponents of "reinvention" assert that it will produce governments that are more agile, better able to adapt to rapidly changing conditions, and able to produce public services at much lower cost. However, attempts to make government "work better and cost less" have had limited success. Policy-makers have consequently invested their creative energy in another class of institutional innovations: segregated funding strategies, which protect agencies and programs from the impact of fiscal restraint by excluding them from normal budgeting processes. The proliferation of budget "lockboxes" may actually introduce new rigidities into the public sector and erode democratic influence in policy-making. On the other hand, there may be some circumstances in which these devices can be justified as a method of ensuring that critical long-run interests receive appropriate attention.     

Blast Suppression Foam,Aqueous Gel Blocks,and their Effect on Subsequent Analysis of Forensic Evidence*

In addition to having blast mitigation properties, aqueous foam concentrate AFC-380 blast suppression foam is designed to capture aerosolized chemical, biological, and radioactive particles during render-safe procedures of explosive devices. Exposure to aqueous environments and surfactants may negatively affect forensic evidence found at the scene, but the effects of AFC-380 foam and aqueous gel on the preservation and subsequent analysis of forensic evidence have not previously been investigated. Sebaceous finger and palm prints and DNA samples on paper, cardboard, tape, and various metal and plastic items, along with hairs, carpet and yarn fibers, and inks and documents, were exposed to AFC-380 foam. Similar mock evidence was also exposed to a superabsorbent gel of the type found in aqueous gel blocks used for shrapnel containment. Exposure to foam or aqueous gel was associated with a dilution effect for recovered DNA samples, but quality of the samples was not substantially affected. In contrast, exposure to AFC-380 foam or gel was detrimental to development of latent finger and palm prints on any substrate. Neither the hair nor the fiber samples were affected by exposure to either the foam or gel. Indented writing on the document samples was detrimentally affected by foam or gel exposure, but not inks and toners. The results from this study indicate that most types of forensic evidence recovered after being exposed to aqueous gel or blast suppression foam can be reliably analyzed, but latent finger and palm prints may be adversely affected.
