Change blindness can cause mistaken eyewitness identification

The current study investigated the effects of change blindness and crime severity on eyewitness identification accuracy. This research, involving 717 subjects, examined change blindness during a simulated criminal act and its effects on subjects' accuracy for identifying the perpetrator in a photospread. Subjects who viewed videos designed to induce change blindness were more likely to falsely identify the innocent actor relative to those who viewed control videos. Crime severity did not influence detection of change; however, it did have an effect on eyewitness accuracy. Subjects who viewed a more severe crime ($500 theft) made fewer errors in perpetrator identification than those who viewed a less severe crime ($5 theft). This research has theoretical implications for our understanding of change blindness and practical implications for the real‐world problem of faulty eyewitness testimony.     

Efficacy of Several Candidate Protein Biomarkers in the Differentiation of Vaginal from Buccal Epithelial Cells*

Abstract: Currently, there is no accurate method to differentiate vaginal epithelial cells from buccal epithelial cells in biological samples typically encountered in forensic casework. This study tested the expression of a selection of candidate proteins in buccal and vaginal epithelial cells. We investigated six candidate biomarkers, such as loricrin, vimentin, stratifin, cytokeratin 4, cytokeratin 13, small proline‐rich protein 2, and involucrin, using Western blot analysis on whole protein extracts and immunohistochemistry (IHC) on intact cells in an attempt to identify cell‐specific markers that would differentiate these cells by microscopy. Involucrin, loricrin, and stratifin showed differential expression during Western blot analysis and were carried through to IHC. Although proteins unique to vaginal epithelial cells and buccal epithelial cells were not identified from among the proteins tested, the increased expression levels of two proteins, loricrin and stratifin in vaginal cells, when compared to buccal cells, do provide encouraging results in the search for epithelial cell‐specific markers.     

The Wang Lixiong prophecy: ‘Palestinization’ in Xinjiang and the consequences of Chinese state securitization of religion

ABSTRACT

In Your Western Regions, My Turkestan (2007), Chinese dissident Wang Lixiong warned of the ‘Palestinization’ of the Xinjiang question, defined as reaching ‘a critical point in time’ where Uyghurs and Han Chinese enter an interminable ‘ethnic war’. Following the knife attack on Han civilians in Kunming (2014), seen by many as an act of Uyghur terror, Wang reminded us that he had foreseen this trajectory seven years earlier. This article outlines Wang’s six interpretations of ‘Palestinization’ in the Xinjiang context, then shows how tightened regulations on religion and intrusive religious policing was the main catalyst for local retaliatory violence in 2012–2015. I contend that state securitization of religion was counterproductive, heightening societal insecurity and promoting inter-ethnic conflict between Uyghur and Han communities. In Chen Quanguo’s era of ‘de-extremification’, the state’s purported attempt to ‘purify’ Islamic practice continues to be experienced on the ground as violation of pure, halal space.
