Investigation into the merits of infrared imaging in the investigation of tattoos postmortem

Infrared imaging has a history of use in the forensic examination of artwork and documents and is investigated here for its wider use in the detection of tattoos on the human body postmortem. Infrared photographic and reflectographic techniques were tested on 18 living individuals, displaying a total of 30 tattoos. It was observed that neither age, sex, age of the tattoo, nor, most significantly, skin color affected the ability to image the tattoos using infrared imaging techniques. Second, a piglet carcass was tattooed and the impact of the decomposition process on the visibility of the tattoos assessed. Changes were recorded for 17 days and decomposition included partial mummification and skin discoloration. Crucially, the discoloration was recorded as greatly affecting the image quality using conventional photography, but was insignificant to the infrared recording of these tattoos. It was concluded that infrared reflectography was beneficial in the investigation into tattoos postmortem.     

Electoral entry and success of ethnic minority parties in central and eastern Europe: A hierarchical selection model

The paper examines determinants of electoral entry and success of ethnic minority parties in central and eastern Europe. The application of a hierarchical selection model shows that the strategic entry of minority parties depends on their expected electoral success due both to observed and unobserved factors. Drawing on formal models of electoral entry, the electoral success of new (or niche) parties is expected to be influenced by the costs of entry (determined by electoral thresholds) and the potential for electoral support. The latter depends on the reactions of political competitors and electoral demand, measured here as the size of ethnic groups and the saliency of ethnic issues. In line with these expectations, parties only run if they can expect electoral support sufficient to pass the electoral threshold. This finding would have been overlooked by a naïve model of electoral success which does not take self-selection into account.     

Political support through representation by the government. Evidence from Dutch panel data

Research on political support demonstrates that satisfaction with democracy is higher among electoral winners than losers, and that it is higher for citizens who are ideologically more congruent with the government. In this paper, I analyze how support for the political system is affected by representation by the government. Expanding on previous studies, I leverage long-run panel data from the Dutch LISS panel spanning over several electoral cycles. Drawing on various measures that go beyond the distinction between election winners and losers and also measure how close citizens are to the government coalition as a whole, I show that being well represented by the government has a wide-ranging positive relationship with satisfaction with democracy, external efficacy and trust in political institutions. While this relationship is mostly short-run, political support can decline substantially if non-representation persists in the long-run. This highlights the relevance of long-run panel data for studying the consequences of representation.
