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.     

The erosion of the administrative state under President Trump: Citizens' pushback against individual and institutional racism

President Trump encouraged bad state actors within the administrative state to contribute to inequities for civilians. We highlight how Trump's actions and rhetoric led to increased individual, institutional, and systemic racism and violence. As a response to this increased violence and rhetoric, we discuss the role civilians (including professional athletes) played in engaging in protests and the 2020 election. Given that more individuals voted in that election cycle, we emphasize the importance for public administration to adapt, evolve, and engage with new actors concerned with administrative action or inaction.     

Groups in Context: An Ontology of a Muslim Headscarf in a Nazareth Catholic School and a Sephardic Ultra‐Orthodox Student in Immanuel

Two separate Israeli Supreme Court cases permitted a Christian school in Nazareth to exclude a Muslim student who insisted on coming to school with her headscarf, and denied an Ashkenazi ultra‐Orthodox school in Immanuel permission to exclude Sephardic students. Intriguingly, the Israeli Supreme Court reached these apparently contradictory holdings using the same liberal ideals of equality and commonality. The article analyzes both holdings to show that the Court's resolutions cannot stand on their own terms. To reconcile these outcomes, we must locate the groups involved within the religious and ethnic power structure in Israel and determine the legal and social significance of defining the group as a minority or a majority. In general, we should be more tolerant of exclusionary measures practiced by a minority than those practiced by the majority. Ultimately, a constitutional evaluation committed to basic individual freedoms cannot refer to the individual without her or his group.

The Interactions and Experiences of Armenians and Jews in the Ottoman Empire and Republic of Turkey from the Young Turk Revolution of 1908 to the Present

This article will examine the interactions of Armenians and Jews as well as shared and dissimilar experiences in the Ottoman Empire and the Republic of Turkey from the early 20th century to the present to compare how affinities and differences in political outlook have affected their relationship. It has been stated at times in academia, by politicians, and members of the press that the Armenian and Jewish Diasporas have had similar historical experiences mostly through hardships. Despite that being the case, this article will show that throughout their experiences as non-Muslim minorities in the Ottoman Empire and the Republic of Turkey Armenians and Jews have never developed any coordinated collaboration; instead, they have pursued perceived respective ethnic interests, largely influenced by historical memory and geopolitics. At the same time, the Young Turks and later the Turkish state engaged in policies, especially toward non-Muslim minorities, that have been described as contradictory, ambivalent, or both in nature, influenced by changing perceptions of citizenship and identity as well as geopolitics.
