The Forward Specialization Coefficient: Distributional Properties and Subgroup Differences

For both public policy and theoretical reasons, criminologists have been interested in the degree to which criminal offenders specialize in particular crimes. Traditionally, offense specialization has been measured with the forward specialization coefficient (FSC). Recently, the FSC has been criticized for being interpretationally obtuse and having no known sampling distribution. In this paper we examine both the interpretational and the statistical properties of the FSC. We conclude that (1) it has an intuitive interpretation that is no less useful than either a standard correlation coefficient or its competitors, (2) its sampling distribution is approximately normal, and (3) the conventional formula for the estimated standard error of the FSC may underestimate the true standard error in some circumstances. With these results behind us, we propose and illustrate both a parametric statistical test for the difference between two independent FSCs and two nonparametric alternatives.     

A path analytic approach to the validation of a taxonomic system for classifying child molesters

This study examined the validity of the most recent revision of a taxonomy for child molesters developed at the Massachusetts Treatment Center (MTC:CM3). The taxonomy is distinguished both from earlier versions of this system and from other systems, by three major changes: (a) the partitioning of the regressed/fixated dichotomy into two separate factors-level of social competence and degree of fixation on children, (b) the introduction of a new type (narcissistic) to fill an empirically determined gap between the object-related offender and the antisocial, exploitative offender, and (c) the differentiation of the violence in the sexual offense into nonsadistic and sadistic components. MTC:CM3 was used to classify 177 child molesters who were committed to the Treatment Center. Variables coded from the clinical files were rationally grouped according to developmental period and subjected to principal-components analysis (PCA). The PCA-derived components then were entered into a series of regression analyses. The resulting three path models indicated that the new subtypes created by the aforementioned refinements had distinct developmental courses and adult adaptations.     

The Good Case: Decisions to Litigate at the World Trade Organization

This article draws upon the law-in-action, repeat players, and motive to understand how legal actors construct the "good case" in dispute settlement systems. The construction of "good cases" is examined at the World Trade Organization (WTO), a relatively new and unexplored site for the study of dispute settlement. Findings show that the good case encompasses flexible sets of motives including economic, political, and symbolic characteristics of trade grievances to mobilize WTO law. The flexibility is due to uncertainties associated with litigation, which are manifestations of four features of the WTO: the newness of the system, the organizational and legal structure of the dispute system, the context of the WTO as an intergovernmental agreement, and the persistence of inequality between states. Six variations of the good case are identified.
