Using spectral information in forensic imaging

Improved detection of forensic evidence by combining narrow band photographic images taken at a range of wavelengths is dependent on the substance of interest having a significantly different spectrum from the underlying substrate. While some natural substances such as blood have distinctive spectral features which are readily distinguished from common colorants, this is not true for visualization agents commonly used in forensic science. We now show that it is possible to select reagents with narrow spectral features that lead to increased visibility using digital cameras and computer image enhancement programs even if their coloration is much less intense to the unaided eye than traditional reagents. The concept is illustrated by visualising latent fingermarks on paper with the zinc complex of Ruhemann's Purple, cyanoacrylate-fumed fingerprints with Eu(tta)(3)(phen), and soil prints with 2,6-bis(benzimidazol-2-yl)-4-[4'-(dimethylamino)phenyl]pyridine [BBIDMAPP]. In each case background correction is performed at one or two wavelengths bracketing the narrow absorption or emission band of these compounds. However, compounds with sharp spectral features would also lead to improved detection using more advanced algorithms such as principal component analysis.     

Is harmonization of legal rules an appropriate target? Lessons from the global financial crisis

This article deals critically with the call for a comprehensive harmonization of legal rules, against the background of the lessons from the recent financial crisis. Before coming to the topic of harmonization of legal rules, it first briefly deals with the question of why rules are necessary at all, and what the functions of rules are. Then it deals with the lessons from the recent financial crisis for the topic mentioned. The article conducts a kind of cost-benefit analysis of legal harmonization by looking at arguments in favor of and against uniform rules. It shows that not only the arguments in favor have increased after the recent financial crisis, but also the arguments against. It also shows that integration of global markets has not only increased the need for new uniform rules but also decreased the chances of their implementation; and that therefore today it is often better to improve the implementation of current rules instead of laying down new uniform rules.     

Game of Power Within the French Urban Landscape: A Socio-legal Semiotic Analysis of Communication,Vision and Space

This paper explores the role and impact of advertising in the French urban planning on citizens’ perception with a close examination of the implications and connections between citizens and outdoor advertising. Significant changes in quantity and form of outdoor advertising have been defined under French regulations. Our knowledge is now mass mediated in public spaces. More and more visible and gargantuan advertising signs surround and even invade our environment for strict commercial benefits. The ‘invasion’ of commercial signs can be compared to a visual pollution affecting our perception, autonomy in thinking and health depending on the part of the population being considered.     

Comment on Andreas von Hirsch: The Roles of Harm and Wrongdoing in Criminalisation Theory

Whereas liberals tend to emphasize harm as the decisive criterion for legitimizing criminalisation, moralists take a qualified notion of wrongfulness as sufficient even when no harm is at hand. This comment takes up Andreas von Hirsch’s “dual element approach” requiring both harm and wrongfulness as necessary conditions for criminalisation and argues that Joel Feinberg’s account of harming as violation of moral rights is perfectly compatible with it. Subsequently, two issues from the liberalism-moralism debate on criminalisation are examined: The difficulty of how to determine wrongfulness beyond the scope of harming, and the so far disregarded question of whether the democratic legislator is free within the framework of constitution to criminalise whatever conduct he wants to prevent irrespective of philosophical constraints.     

Some stylised facts about cash and black economies in Germany

The currency approach assumes black economies to entail larger cash volumes than those needed for transactions in the official economy. Estimates of this hypothesis use e.g. overall cash data. But, for the case of Germany, the growing DM cash amounts in circulation did not only accompany transactions in the national economy, they also disseminated in hoards and in international uses. A series of adjusted cash figures is derived which shows the maximum dimension of national cash uses either for official or black activities. The adjusted cash figures in general grew less fast than overall cash, private consumption, GDP or M1 respectively. They even diminished relative to sales figures which often are accused of being a basis for black activities. This enhances the presumption that, contrary to some contentions in the literature, black activities during the times of the DM-regime played a minor or even decreasing role in Germany.     

Verfassungsfragen einer Reform des österreichischen Bundesheeres

Die Diskussion über eine Abschaffung der Wehrpflicht und einen Umbau des österreichischen Wehrsystems muss auch die verfassungsrechtlichen Rahmenbedingungen mit in den Blick nehmen. Die Bundesverfassung verankert nicht nur die allgemeine Wehrpflicht und das Milizsystem als Organisationsmaximen des Bundesheeres, sondern trifft auch eine abschließende Regelung der Aufgaben des Bundesheeres. Darüber hinaus ergeben sich aus der Neutralität Österreichs und aus dem in Art 4 EMRK normierten Verbot von Zwangs- und Pflichtarbeit verfassungsrechtliche Kriterien, die bei der Entscheidung für ein bestimmtes Wehrsystem zu beachten sind.
