Portable high‐resolution automated 3D imaging for footwear and tire impression capture

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.     

The association between childhood sexual abuse and sexual coercion in men: a test of possible mediators

ABSTRACT

We examined the associations between childhood sexual abuse (CSA), childhood physical abuse (CPA), sexual domain variables, antisocial tendencies, and sexually coercive behaviour in a non-forensic sample of 173 heterosexual men. CSA was associated with paraphilic interests and experiences, a more extensive sexual life history, and early antisocial tendencies. CPA was associated with paraphilic interests and experiences, more self-reported delinquency, higher sensation seeking, and early antisocial tendencies. Sexual domain variables (e.g. number of sexual partners, sexual interest in sadomasochism) mediated the link between CSA and sexually coercive behaviour, but antisocial domain variables (e.g. delinquency, sensation seeking) did not. Of the two sexual domains examined, extensive sexual life history rather than paraphilias mediated the association between CSA and sexually coercive behaviour. These results suggest CSA and CPA are associated with both sexual and antisocial outcomes, and that, for some victims of CSA, having an extensive sexual life history may account for the association between CSA and sexually coercive behaviour later in life.     

Female leaders and citizens' perceptions of political parties

ABSTRACT

Do female leaders affect voters' perceptions of political parties' placement on the left-right spectrum? Using public opinion data on 269 parties in 35 countries between 1976 and 2016, I show that female-led parties are perceived as more moderate than male-led organizations, even when accounting for voters' prior beliefs about the party and the organization's stated policy positions. I then demonstrate that these results cannot be explained by the policy platforms authored by male- and female-led parties. The electoral manifestos produced by female-headed organizations are neither more left- leaning nor more moderate than those authored under male leaders. Together, these results provide important insights concerning citizens' (mis)perceptions of parties' ideological positions, party leaders' effects on voters behavior, the importance of gender stereotypes in politics, and the policy consequences of women's increased access to power.     

Quality of democracy in unrecognized states: lessons from Northern Cyprus

Scholars have recently debated whether non-recognition is a blessing or a curse for democracy. Some suggest that lack of recognition forces political elites to democratize and acquire internal legitimacy to compensate for the lack of external legitimacy. Others suggest that democratization is used as a strategy by which to acquire international recognition. Still others claim that non-recognition obliges unrecognized states to rely on a patron state which, in turn, hinders the quality of democracy. To contribute to this discussion, we have conducted an in-depth case study. Focusing on democratic quality in Northern Cyprus from 2010 to 2016, it is observed that reliance on a patron state leads to dynamics of tutelage, in turn hindering the quality of democracy.     

Unexpected Persistence Amidst Enlargement Stasis: Usages of Europe in Turkey’s Nuclear Energy Debate

Recent studies on European Union (EU) Enlargement have emphasised the importance of usages of ‘Europe’ by domestic actors as a necessary condition for the EU to have an impact on domestic politics. We study the usages of Europe in the critical case of Turkey’s nuclear energy policy. We analyse the narratives and actions of domestic actors in Turkey to identify if they use ‘Europe’ (the EU and the idea of Europe). We reach the counter-intuitive finding of usages by both state and non-state actors, which illustrates that usages of Europe can persist despite enlargement stasis in candidate states.
