Historical Circumstances and Theoritical Structures as Sources of Meaning: A Response

The place of theory as providing a context for meaning is furtherelaborated on the presumption that an individuality principleor theorem of fundamental theoretical importance is being advancedby Alexander Hamilton in Federalist 15 and 16. Following ErnstCassirer, the argument is advanced that theoretical definitionsdepend upon a computational logic that enables one to statecausal antecedents that yield a conceptualized effect. Thisis the type of language that is used by artisans to create artifactsincluding those forms of artisanship that are concerned withthe nature and constitution of order in human societies.     

Evaluating the forensic informativeness of mtDNA haplogroup H sub-typing on a Eurasian scale

The impact of phylogeographic information on mtDNA forensics has been limited to the quality control of published sequences and databases. In this work we use the information already available on Eurasian mtDNA phylogeography to guide the choice of coding-region SNPs for haplogroup H. This sub-typing is particularly important in forensics since, even when sequencing both HVRI and HVRII, the discriminating power is low in some Eurasian populations. We show that a small set (eight) of coding-region SNPs resolves a substantial proportion of the identical haplotypes, as defined by control-region variation alone. Moreover, this SNP set, while substantially increasing the discriminating efficiency in most Eurasian populations by roughly equal amounts, discloses population-specific profiles.     

Juvenile sex offenders: a complex population

Individuals who engage in sexual offending behavior represent a heterogeneous population. Recent research has found some success in categorizing sexual offenders based on a number of variables, particularly the type of victim. For example, differences have been found between those offenders who victimize adults when compared with those who victimize children. However, the research in this area has been conducted predominantly with adult samples. As the adult sex offender literature has progressed, it has become evident that risk assessment, treatment effectiveness, and risk management are dependent on such offender characteristics. Unfortunately, the relevance to juveniles of characteristics deemed to be important with adult sex offenders is limited due to the complexity of developmental processes, particularly with respect to mental disorders and personality formation. As such, the formulation and implementation of treatment and risk management strategies that will be effective with juvenile sex offenders are challenging. The goal of this paper is to review some of the complexities inherent in the juvenile sex offender population by focusing on specific areas of complication, including: classification systems, comorbid paraphilias and other mental illnesses, and maladaptive personality traits.     

The Empirical Limits of Forensic Mental Health Assessment

This article introduces a special issue of Law and Human Behavior, including five articles describing the limits of forensic mental health assessments of (a) risk of violence in female adolescents, (b) sexually violent predators, (c) dangerousness in capital murder cases, (d) child sexual abuse, and (e) PTSD litigants. Knowing the limits of forensic mental health assessment methods is essential in order to recognize their strengths, increase the credibility of forensic mental health assessment, and drive research that will enhance the value of assessments for the courts.
