Ink dating,part I: Statistical distribution of selected ageing parameters in a ballpoint inks reference population

The development of ink dating methods requires an important amount of work in order to be reliably applicable in practice. Major tasks include the definition of ageing parameters to monitor ink ageing. An adequate parameter should ideally fulfil the following criteria: it should evolve as a function of time in a monotonic way, be measurable in a majority of ink entries, be as accurate and reproducible as possible, and finally it should not be influenced too much by transfer and storage conditions. This work aimed at evaluating the potential of seven ageing parameters for ink dating purposes: the phenoxyethanol quantity, relative peak areas (RPA), three solvent loss ratios (R%, R%*, NR%) and two solvent loss parameters (R_NORM, NR_NORM). These were calculated over approximately one year for 25 inks selected from a large database to represent different ageing behaviours. Ink entries were analysed using liquid extraction followed by GC/MS analysis. Results showed that natural ageing parameters (NR% and NR_NORM) were not suitable ageing parameters for ink entries older than a few weeks. RPA used other compounds present in ink formulations in combination to PE in order to normalise the results. However, it presented particular difficulties as they could not be defined for all inks and were thus applicable only for 64% of the studied inks. Finally, the PE quantity, R% and R_NORM allowed to follow the ageing of the selected inks over the whole time frame and were identified as the most promising. These were thus selected to test three different interpretation models in the second part of this article. The possibilities and limitations of ink dating methods will be discussed in a legal perspective.     

Effectiveness of a risk–need–responsivity‐based treatment program for violent and sexual offenders: Results of a retrospective,quasi‐experimental study

Purpose

Relapse prevention is an important goal in correctional settings. Although there is strong evidence for the effectiveness of certain treatment programs for juvenile offenders, those for adults lack such evidence. This study evaluated the effectiveness of a risk–need–responsivity (RNR)‐based intervention.

Methods

A quasi‐experimental, observational study design and cox regression analysis were used to compare treated violent and sexual offenders (n = 171) with untreated offenders (n = 241).

Results

Both groups were observed for an average of 7.9 years. Recidivism rates of treated offenders (11.7%, n = 20) were similar to those of control offenders (15.8%, n = 38; p = .25). When controlling for confounding variables, the hazard of recidivism in the treatment group was 5.2% lower than that in the control group. Subdividing the treatment group resulted in lower hazard ratios for offenders still in therapy when released and offenders cancelling therapy. However, none of the group differences was statistically significant.

Conclusion

Our results show that control and RNR‐based treatment groups had comparable recidivism rates with a trend towards a positive treatment effect, especially for people in outpatient treatment. However, criminal history, age at the start of follow‐up, and actuarial risk of recidivism were significantly associated with recidivism. Future research needs to apply elaborate methodological approaches to detect robust treatment effects and consider different criteria of treatment effectiveness. Furthermore, the influence of prison climate, motivational factors, intervention quality, and factors supporting the success of outpatient treatment should be considered in future studies of larger offender samples.     

Reactions to Crime as a Hierarchy Regulating Strategy: The Moderating Role of Social Dominance Orientation

Across two studies, we demonstrated that support for group-based hierarchies differentially affects evaluation of ingroup and outgroup criminal offenders and that this effect generalizes to overall evaluations of their respective groups. Drawing on social dominance theory, our results show that differential judgments of national ingroup and immigrant outgroup offenders reflect hierarchy regulating strategies. Study 1 (N = 94) revealed that egalitarians (low on SDO) were more lenient toward outgroup offenders and their ethnic group (Arab immigrants) when compared to ingroup offenders and their national group (Swiss citizens). The opposite was true for social dominators (high on SDO). Study 2 (N = 88) replicated the results of Study 1 and further demonstrated that the socio-economic status of the perpetrator did not affect perpetrator group evaluations suggesting that the arbitrary sets of ethnicity or nationality, not education level and employment status, were the important cues for hierarchy-regulating judgments of criminal offenders.     

Integrity,culture, and scale: an empirical test of the big bad police agency

Building on Klockars et. al. (2000) analysis of survey data on police agency integrity, this analysis develops an economic model of police corruption within police agencies. Empirical estimates of the economic model are consistent with Klockars et. al. (2000) in that there is no evidence to support the traditional theory that police agency corruption is attributable to the “individual bad-apple.” Independent of other factors, the present analysis shows that police culture fosters corruption. Furthermore, the present analysis shows that incentive structures within police agencies increase the problem of corruption as the scale of police agency operation increases. Policies that would promote higher levels of integrity are considered.     

EU Citizenship and Political Identity: The Demos and Telos Problems

Citizenship is the cornerstone of a democratic polity. It has three dimensions: legal, civic and affiliative. Citizens constitute the polity's demos, which often coincides with a nation. European Union (EU) citizenship was introduced to enhance ‘European identity’ (Europeans’ sense of belonging to their political community). Yet such citizenship faces at least two problems. First: Is there a European demos? If so, what is the status of peoples (nations, demoi) in the Member States? The original European project aimed at ‘an ever closer union among the peoples of Europe.’ Second: Citizens are members of a political community; to what kind of polity do EU citizens belong? Does the EU substitute Member States, assume them or coexist alongside them? After an analytical exposition of the demos and telos problems, I will argue for a normative self‐understanding of the EU polity and citizenship, neither in national nor in federal but in analogical terms.

Screening for risk of inpatient violence

A screening checklist for assessing the risk of violence at the time of psychiatric hospitalization was developed. Checklist items and a cutoff point for low versus high risk of violence were selected based on a previous study of statistical prediction of violence. Application of the checklist to a new sample of 338 patients admitted to a university-based inpatient unit revealed promising results in identifying patients who later displayed aggressive behavior in the hospital, as indicated by its positive predictive value (59.0%), negative predictive value (70.6%), sensitivity (57.2%), specificity (70.0%), total predictive value (65.4%), and likelihood ratio (1.97). The results suggest the potential value of incorporating actuarial methods in the evaluation of violence risk.Funded in part by Biomedical Research Support Grant Program grant No. SO7-RR05775 from the Division of Research Resources, National Institutes of Health.
