Early criminal recidivism among mentally disordered offenders

Criminal recidivism was studied during 2 years in a Swedish population-based cohort (N = 318) of mentally disordered male offenders who had undergone a pretrial forensic psychiatric investigation, been convicted in subsequent trials, and been sentenced to forensic psychiatric treatment (FPT; n = 152), prison (n = 116), or noncustodial sanctions (n = 50). Recidivism was analysed in relation to index sanctions, levels of supervision, diagnoses, and criminological factors. Significantly lower recidivism in the FPT group was related to lower crime rates during periods at conditional liberty in this group alone, and recidivism was significantly more common among offenders with at least one of the two diagnoses of substance abuse disorder and personality disorder than among those with psychotic or other mental disorders alone. Age at index crime and number of previous crimes emerged as significant predictors of recidivism. The results of this study suggest that the relapse rates depend as much on level of supervision as on individual characteristics.     

On non-invasive 2D and 3D Chromatic White Light image sensors for age determination of latent fingerprints

The feasibility of 2D-intensity and 3D-topography images from a non-invasive Chromatic White Light (CWL) sensor for the age determination of latent fingerprints is investigated. The proposed method might provide the means to solve the so far unresolved issue of determining a fingerprints age in forensics. Conducting numerous experiments for an indoor crime scene using selected surfaces, different influences on the aging of fingerprints are investigated and the resulting aging variability is determined in terms of inter-person, intra-person, inter-finger and intra-finger variation. Main influence factors are shown to be the sweat composition, temperature, humidity, wind, UV-radiation, surface type, contamination of the finger with water-containing substances, resolution and measured area size, whereas contact time, contact pressure and smearing of the print seem to be of minor importance. Such influences lead to a certain experimental variability in inter-person and intra-person variation, which is higher than the inter-finger and intra-finger variation. Comparing the aging behavior of 17 different features using 1490 time series with a total of 41,520 fingerprint images, the great potential of the CWL technique in combination with the binary pixel feature from prior work is shown. Performing three different experiments for the classification of fingerprints into the two time classes [0, 5h] and [5, 24h], a maximum classification performance of 79.29% (kappa=0.46) is achieved for a general case, which is further improved for special cases. The statistical significance of the two best-performing features (both binary pixel versions based on 2D-intensity images) is manually shown and a feature fusion is performed, highlighting the strong dependency of the features on each other. It is concluded that such method might be combined with additional capturing devices, such as microscopes or spectroscopes, to a very promising age estimation scheme.     

Suicide by multiple blunt head traumatisation using a stone

Apart from collisions with road or rail vehicles and falls from height, self inflicted blunt force is a rare suicide method and mainly seen in psychiatric patients. The paper presents a rare case of suicide by active blunt force. A 68-year-old man committed suicide by repeatedly hitting his head with a stone. He sustained a craniocerebral trauma and finally died from hypothermia due to the low outdoor temperature. According to the relatives, the man was not diagnosed with a mental disorder or suicidal tendencies. Uncommon manners of self-harm are challenging for those involved in the investigation, and a differentiation between suicide, accident and homicide can only be made in synopsis of all findings.     

Influence of CYP2D6 genotype on the disposition of the enantiomers of venlafaxine and its major metabolites in postmortem femoral blood

Venlafaxine (VEN) is an antidepressant drug mainly metabolized by the cytochrome P450 (CYP) enzyme CYP2D6 to the active metabolite O-desmethylvenlafaxine (ODV). VEN is also metabolized to N-desmetylvenlafaxine (NDV) via CYP3A4. ODV and NDV are further metabolized to N,O-didesmethylvenlafaxine (DDV). VEN is a racemic mixture of the S- and R-enantiomers and these have in vitro displayed different degrees of serotonin and noradrenaline reuptake inhibition. The aim of the study was to investigate if an enantioselective analysis of VEN and its metabolites, in combination with genotyping for CYP2D6, could assist in the interpretation of forensic toxicological results in cases with different causes of deaths. Concentrations of the enantiomers of VEN and metabolites were determined in femoral blood obtained from 56 autopsy cases with different causes of death. The drug analysis was done by liquid chromatography tandem mass spectrometry (LC/MS/MS) and the CYP2D6 genotyping by PCR and pyrosequencing. The mean (median) enantiomeric S/R ratios of VEN, ODV, NDV and DDV were 0.99 (0.91), 2.17 (0.93), 0.92 (0.86) and 1.08 (1.03), respectively. However, a substantial variation in the relationship between the S- and R-enantiomers of VEN and metabolites was evident (S/R ratios ranging from 0.23 to 17.6). In six cases, a low S/R VEN ratio (mean 0.5) was associated with a high S/R ODV ratio (mean 11.9). Genotyping showed that these individuals carried two inactive CYP2D6 genes indicating a poor metabolizer phenotype. From these data we conclude that enantioselective analysis of VEN and ODV can predict if a person is a poor metabolizer genotype/phenotype for CYP2D6. Knowledge of the relationship between the S- and R-enantiomers of this antidepressant drug and its active metabolite is also important since the enantiomers display different pharmacodynamic profiles.     

Der Abschluss von Swap-Geschäften durch Gemeinden und die Grenzen der Gemeindeautonomie

Gemeinden haben mit Swap-Geschäften zur Absicherung des Zinsrisikos teilweise erhebliche Verluste erlitten. Dieser Umstand führt mittlerweile auch zu Gerichtsverfahren, in welchen die Gültigkeit dieser Geschäfte streitgegenständlich ist. Im folgenden Beitrag werden die Voraussetzungen für die Gültigkeit von Swap-Geschäften der Gemeinden untersucht.     

Law defining the critical level of driver fatigue in terms of hours without sleep: Criminal justice professionals' opinions and fatal accident data

The aims of the present study were to determine the support among criminal justice professionals for a law that defines the critical limit of driver fatigue in terms of 24 consecutive hours of wakefulness; and to determine how many drivers causing fatal accidents would be potentially covered by such a law. The data included an online questionnaire data collected from 325 criminal justice professionals (96 prosecutors, 129 traffic police officers, and 100 local police officers with experience in traffic surveillance and accident investigations) and the national database of fatal road accidents studied in depth (N = 1871; 2002–2008). The support for such a law was quite low among prosecutors while police officers were more in favor than against it. Only a handful of the (survived) drivers who caused a fatal accident were awake for more than 24 consecutive hours. We discuss several challenges and considerations associated with such a law.     

Agilität als Chance für einen neuen Anlauf zum demokratischen Unternehmen?

There has been a long-standing discussion since the 1980s about the question whether new production models harbor a potential for extended employee participation and involvement, in most cases with disillusioning results. This paper is concerned with so called “agile methods”, which play an important part in the area of knowledge work in the course of the digital transformation. On the basis of two case studies from software development and industrial R&D, the paper examines the concrete implementation of these methods and the employees’ perspective upon them and their consequences. The result is that agile methods present a potential for extended employee participation and involvement; however, the realization of this potential depends on the concrete way how the agile concept of “empowerment” is implemented.     

Ahmadis or Indonesians? The polarization of post-reform public debates on Islam and orthodoxy

Since the fall of Suharto in 1998, Indonesian public discourse about “mainstream” Muslim identity and practice has polarized sharply into various factions. This article offers a detailed analysis of a subset of this discourse that focuses on the Ahmadiyya in order to grasp how the new normative contours of Islam are being shaped in Indonesia. I make three arguments: First, the discourse is homogenizing what was once a wide spectrum of identitarian positions, and that consequently, Islamic diversity in Indonesia is shrinking. Second, the various internally homogenized sets of arguments for and against the Ahmadiyya mis-engage with each other in a way that produces social fragmentation and further polarization. Third, these arguments produce exclusionary mechanisms that reinforce each other. Both the opponents of the Ahmadiyya and their defenders exclude Ahmadis from conceptions of an Indonesian “majority.” This dynamic in Indonesian public discourse has resulted in the acceleration of the marginalization of the Ahmadiyya within an increasingly fragmented Indonesian society.
