Intoxicated eyewitnesses: Better than their reputation?

According to law enforcement, many witnesses are intoxicated either at the time of the crime, the interview, or both (Evans et al., Public Policy Law 15(3):194-221, 2009). However, no study to date has examined whether intoxicated witnesses' recall is different from sober witnesses' and whether they are more vulnerable to misinformation using an ecologically valid experimental design. Intoxicated, placebo, and sober witnesses observed a live, staged theft, overheard subsequent misinformation about the theft, and took part in an investigative interview. Participants generally believed they witnessed a real crime and experienced a real interview. Intoxicated witnesses were not different from placebo or sober witnesses in the number of accurate details, inaccurate details, or "don't know" answers reported. All the participants demonstrated a misinformation effect, but there were no differences between intoxication levels: Intoxicated participants were not more susceptible to misinformation than sober or placebo participants. Results are discussed in the light of their theoretical and applied relevance.     

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.     

In vitro production of GHB in blood and serum samples under various storage conditions

The in vitro production of GHB was observed in freshly collected, untreated whole blood samples using glass BD-Vacutainers and polypropylene S-monovettes. GHB concentrations were determined daily over a period of one week and after 3, 6 and 9 weeks again. Furthermore, the GHB concentration in 40 untreated random whole blood samples stored at 4°C for a longer period of time (10 samples 12 month, 10 samples 24 month and 20 samples 36 month) was also determined. For comparison, the in vitro production of GHB in freshly collected and prepared serum samples was observed. GHB serum concentrations were determined three times over a period of one week and once again after six weeks. Sample preparation was performed by means of methanolic extraction following the precipitation of whole blood and serum samples. A methanolic standard calibration was done in a low range of 0.005-0.1 μg/mL (LOD: 0.004, LLOQ: 0.013). For quantification a spiked blood bank serum with a determined GHB concentration of 0.09 μg/mL was used. Corrected calibrations in the range of 0.09-5.09 μg/mL were used (LOD: 0.08 μg/mL, LLOQ: 0.30 μg/mL), recovery: 91.3% (high level: 4.09 μg/mL) 50.5% (low level: 0.19 μg/mL). RESULTS: Relevant elevation of GHB was observed in all whole blood samples stored in liquid form (4°C or room temperature). In two of the 40 whole blood samples stored over a longer period of time at 4°C, GHB concentrations in the range of 13 μg/mL were even determined. These findings constitute grounds for caution. Even a GHB cut-off level of 5 μg/mL cannot be considered as "absolutely positive" proof of a case of exogenous administration, at least in untreated liquid blood samples in long time storage. However, no significant elevations of GHB were otherwise observed in any of the serum samples independently of storage temperature nor in the whole blood samples that were frozen for storage. CONCLUSIONS: The results suggest that the cut-off for exogenous GHB of 5 μg/mL could be lowered significantly, with the consequence of winning valuable time for the potential victim, but only if serum is collected for GHB determination or if the whole blood sample is frozen immediately after collection and the procedure well documented.     

Ready to leave the ivory tower?: Academic scientists’ appeal to work in the private sector

This study investigates the factors that shape the attitudes of scientists toward starting their own business or working in a private sector firm. The analysis is based on data collected from scientists working in the German Max Planck Society, a research institution devoted to basic science. We find that the scientists’ attractiveness of working in a private sector firm or of starting their own business differ considerably according to their academic discipline and the self-reported commercial potential of their research. The ability to take risks, prior work experience in private firms, and personal experience in cooperating with industry lead to a positive attitude towards switching to private sector employment or entrepreneurship. Strong willingness to freely distribute research findings is related to a low appeal of private sector work.     

Wohnungsgemeinn��tzigkeit im Binnenmarkt

Das ?sterreichische Wohnungsgemeinn??tzigkeitswesen ist ein eigener Weg sozialer Wohnungspolitik, der von Bund und L?ndern durch Steuervorteile und Wohnbauhilfen gef?rdert wird. Im Beitrag wird untersucht, inwiefern diese F?rderung als Beihilfe iSd Art 107 AEUV zu qualifizieren ist und ob sie - unter Ber??cksichtigung aktueller Rechtsentwicklungen - mit den Regeln des Binnenmarkts vereinbar ist.     

“Because That’s What Justice Is to Us”: Exploring the Racialized Collateral Consequences of New Parochialism

Renewed interest in communities as spaces for criminal opportunity has generated numerous studies of neighborhood social dynamics and crime. Most of this research is rooted in social disorganization theory, which examines neighborhood structural characteristics that facilitate effective social control. While many studies tout the benefits of community-based controls, the potential externalities of these efforts remain underexplored. In the modern neoliberal context, where policing strategies stress community involvement and often focus on vaguely-defined problems like “quality of life” or “incivilities” and where police have considerable enforcement discretion, the unintended consequences of community-based controls are important to document. I use the ethnographic case study of Gardner Village to explore the potential collateral consequences of one form of collective social control: new parochialism. Applying a critical lens to the social disorganization literature, I argue that when embedded in particular structural contexts, new parochialism contributes to the reproduction of inequality and undermines community-building processes.     

Democratic Legitimacy in the Bund or ‘Federation of States’: the Cases of Belgium and the EU

Carl Schmitt developed the concept of the ‘federation of states’ (Bund) in order to characterise intermediate constitutional systems which are integrated beyond the level of a confederation (Staatenbund) without, however, acquiring the level of integration of an actual federal state (Bundesstaat). In this paper we analyse the constitutional specificity of the ‘federation of states’ and present three normative principles for assessing the democratic legitimacy of the decision‐making procedures within such a federation. We argue that both the European Union and Belgium can be analysed as instances of such a federation of states and show how this characterisation improves our understanding of the evolutionary dynamics of both polities and the constitutional and democratic challenges they are facing.     

The nature of police involvement in mental health transfers

During the course of their duties, police regularly have contact with mentally ill persons who are experiencing psychiatric crisis and require some form of mental health transfer. This study examined 2611 unique mental health transfers completed by police in the Australian state of Victoria over an eight-month period in 2009–2010. The overwhelming majority of mental health transfers performed by police during this period were the result of unplanned calls for assistance. Although police frequently requested assistance from other services, these were often not available. The study findings support a substantial body of anecdotal evidence from police citing lengthy involvement with people experiencing mentally illness, with the average mental health transfer consuming 2.5?h of police time. The frontline responses of police to people in psychiatric crisis need to be more formally acknowledged and creative solutions need to be sought with health and welfare services to better meet the needs of those who are falling between the cracks of community mental health care services.     

Justice ‘Under’ Law: The Bodily Incarnation of Legal Conceptions Over Time

The article uses embodiment and the experiential basis of conceptual metaphor to argue for the metaphorical essence of abstract legal thought. Abstract concepts like ‘law’ and ‘justice’ need to borrow from a spatial, bodily, or physical prototype in order to be conceptualised, seen, for example, in the fact that justice preferably is found ‘under’ law. Three conceptual categories of how law is conceptualised is examined: law as an object, law as a vertical relation, and law as an area. The Google Ngram Viewer, based on the massive library of books that Google has scanned, has been used to study legally relevant conceptions over time within each of these three categories, from 1800 to 2000. In addition, the article suggests a type of analytical method of ‘metaphor triangulation,’ that is, the replacement of prevailing metaphors with unusual ones in order to increase the level of awareness of what conceptual content the prevailing metaphors involve.
