Punishment or treatment?

Although there is strong support among the general public for providing insanity acquittees with mental health treatment, it is also believed that insanity acquittees should be punished when they break the law. Prior studies of the lengths of confinement of insanity acquittees have yielded inconsistent results. This article draws upon a large-scale, multistate study of insanity pleas to explore the question: Is society able to withhold punishment against persons acquitted of criminal charges due to insanity? Results indicate that offense seriousness is a more important factor than mental disorder in determining the lengths of confinement of persons foundNot Guilty by Reason of Insanity and that persons found guilty are more likely to be released without ever having been confined than persons acquited by reason of insanity. Implications for invoking offense seriousness as a primary criterion in assessments of dangerousness are discussed.     

Theoretical Foundations for the Design and Placement of Community-Based Treatment Facilities for Juveniles

With deinstitutionalization and community-based treatment of delinquents becoming more common, the need for facilities compatible with re-integration efforts is crucial. In line with the increasing local needs for dealing with juvenile offenders in the community, this paper advocates the use of delinquency theory as the conceptual foundation for the architectural design and placement of community-based alternatives to incarceration. In addition, we present guidelines for the site selection, community acceptance and physical design of a model community-based treatment facility for minor offenders, which are based on a theoretical integration of social control theory and the labeling approach.     

The Propaganda of the Deed: Terrorism, Counterterrorism, and Mobilization

Many terrorist factions care about the level of popular support they enjoy within a population they claim to represent. Empirically, this level of support can either rise or fall in the aftermath of a campaign of terrorist violence. Under what circumstances is the use of terror an effective tactic for mobilizing political support for an extremist group? This article models a scenario in which an extremist faction considers attacking a government in the hopes of provoking a counterterror response that will radicalize the population, increasing the extremists' support at the expense of a more moderate faction. In our scenario, such radicalization can result either from the economic damage caused by counterterror operations or by the way in which such operations change the population's assessment of the government's motivations. We demonstrate that such attempts at mobilizing public support can be, but need not be, successful, discuss factors that make both the initiation of a terror campaign and successful mobilization more or less likely, and relate our results to several empirical cases.     

Rationales Wählen als Reaktion auf Koalitionssignale am Beispiel der Bundestagswahl 2005

This article extends the calculus of rational voting (Riker/Ordeshook 1968) by considering the coalition building process and the legislative process (cf. Austen-Smith/Banks 1988) in multi-party systems. Comparing coalition preferences and their resulting legislative outcomes instead of party preferences, I elaborate preference profiles of voters on coalitions and estimate the probability that a coalition forms, given the parties’ coalition signals and an expected electoral result. I show the results of this rational calculus for the German Bundestag elections 2005 as a political map. Further, this calculus allows the identification of coalition signals that increase and those that reduce a party’s vote share.     

Profiles in the offending process of nonserial sexual murderers

The aim of this study was to investigate specific pathways in the offending processes of nonserial sexual murderers and to examine possible relationships with different precrime, per-crime, and postcrime factors. Included in this study were 36 offenders who have committed at least one sexual murder against a female victim and they were classified using cluster analysis. Participants using the sadistic pathway planned their offenses and used physical restraints during the offenses. Furthermore, they mutilated and humiliated their victims. Finally, they hid the bodies of the victims. Participants using the anger pathway had not premeditated the homicide. Mutilation, humiliation, and physical restraints were less predominant with these participants than with those using the sadistic pathway. Moreover, these offenders were more likely to leave the bodies at the crime scenes after the killings occurred. These two profiles are compared with empirical studies addressing sexual homicide.     

The influence of staffing levels on the use of seclusion

This study focussed on the relationship between the use of seclusion and staff characteristics, such as number of nurses on shift, male-female staff ratio, level of education and level of work experience. A retrospective analysis of staff characteristics was applied to administrative data from ten wards in four mid-sized general psychiatric hospitals in the Netherlands. The data show that two variables were associated with seclusion rates: the male-female staff ratio and the variability in team's work experience. More female and less male nurses in a shift and less variability in team's work experience predicted an increase in seclusion rates.     

Single-metal deposition (SMD) as a latent fingermark enhancement technique: an alternative to multimetal deposition (MMD)

This paper proposes an alternative solution to multimetal deposition (MMD) for the development of latent fingermarks on non-porous and porous surfaces. MMD offers a good sensitivity, however it is very time-consuming and requires many reagents to be carried out. Single-metal deposition (SMD) replaces the silver enhancement of the gold colloids by a gold enhancement procedure. This reduces the number of baths by one as well as the number of reagents and their cost, utilizes reagents with a longer shelf life, and most importantly reduces the labor-intensity of the procedure. It offers quasi-identical results to MMD and thus makes a very attractive alternative.     

Development of a harmonised method for the profiling of amphetamines VI: Evaluation of methods for comparison of amphetamine

Amphetamine samples were analysed by gas chromatography-mass spectrometry (GC-MS), and the peak areas of 33 target compounds were transformed by applying various pretreatment techniques. The objective was to optimise the ability of a number of distance metrics to establish links between samples of amphetamine originating from the same batch (henceforth referred to as linked distances). Furthermore, partial least squares discriminant analysis (PLS-DA) was used to evaluate the effects of various pretreatment methods on separation of amphetamine batches synthesised by the Leuckart reaction, reductive amination of benzyl methyl ketone, and the nitrostyrene route. The most efficient way to pretreat GC-MS data varied for the different distance metrics, although best results were obtained when data were normalised to the sum of peak areas, and either the fourth root or a logarithm was applied to the normalised data. When pretreating normalised data by fourth root transformation, Pearson correlation was the distance metric that was most successful at finding linked samples. Normalisation and the use of fourth root also represented the best method of pretreating data when employing PLS-DA to separate samples synthesised by different routes. To achieve a faster and more user-friendly procedure for evaluating chromatograms, experiments were performed in which the number of target compounds used to compare samples was reduced. The effect of each compound that was removed was studied by applying PLS-DA and by using Pearson correlation to calculate linked distances as well as unlinked distances (between samples from different batches of amphetamine). Considering both links between samples from the same batch and separation of samples synthesised by different routes, the best results were obtained with the data set comprising 26 compounds. Finally, it was found that the profiling method developed in this work was superior to an existing technique with respect to separating linked and unlinked distances.     

Cannabinoid concentrations in hair from documented cannabis users

Fifty-three head hair specimens were collected from 38 males with a history of cannabis use documented by questionnaire, urinalysis and controlled, double blind administration of delta9-tetrahydrocannabinol (THC) in an institutional review board approved protocol. The subjects completed a questionnaire indicating daily cannabis use (N=18) or non-daily use, i.e. one to five cannabis cigarettes per week (N=20). Drug use was also documented by a positive cannabinoid urinalysis, a hair specimen was collected from each subject and they were admitted to a closed research unit. Additional hair specimens were collected following smoking of two 2.7% THC cigarettes (N=13) or multiple oral doses totaling 116 mg THC (N=2). Cannabinoid concentrations in all hair specimens were determined by ELISA and GCMSMS. Pre- and post-dose detection rates did not differ statistically, therefore, all 53 specimens were considered as one group for further comparisons. Nineteen specimens (36%) had no detectable THC or 11-nor-9-carboxy-THC (THCCOOH) at the GCMSMS limits of quantification (LOQ) of 1.0 and 0.1 pg/mg hair, respectively. Two specimens (3.8%) had measurable THC only, 14 (26%) THCCOOH only, and 18 (34%) both cannabinoids. Detection rates were significantly different (p<0.05, Fishers' exact test) between daily cannabis users (85%) and non-daily users (52%). There was no difference in detection rates between African-American and Caucasian subjects (p>0.3, Fisher's exact test). For specimens with detectable cannabinoids, concentrations ranged from 3.4 to >100 pg THC/mg and 0.10 to 7.3 pg THCCOOH/mg hair. THC and THCCOOH concentrations were positively correlated (r=0.38, p<0.01, Pearson's product moment correlation). Using an immunoassay cutoff concentration of 5 pg THC equiv./mg hair, 83% of specimens that screened positive were confirmed by GCMSMS at a cutoff concentration of 0.1 pg THCCOOH/mg hair.
