Solidarity riots in the diffusion of collective action: Doing historical research to develop theory in social psychology.

Both psychology and historical studies have addressed the question of the diffusion of collective action events, although using very different methodological approaches and with differing concepts. In the present paper, we present a novel approach, combining historiographical research methods with analytic concepts from social psychology, to explore the psychological processes underlying riot diffusion. Using archive data from the 1831 wave of 'reform' riots, thick description of two collective action events provides evidence that the purpose of participants' actions was to prevent troops from passing through their towns to put down riots elsewhere.

Reciprocating thermochemical mediator of pre-biotic polymer decomposition on mineral surfaces.

A continuing frustration for origin of life scientists is that abiotic and, by extension, pre-biotic attempts to develop self-sustaining, evolving molecular systems tend to produce more dead-end substances than macromolecular products with the necessary potential for biostructure and function - the so-called 'tar problem'. Nevertheless primordial life somehow emerged despite that presumed handicap. A resolution of this problem is important in emergence-of-life science because it would provide valuable guidance in choosing subsequent paths of investigation, such as identifying pre-biotic patterns on Mars.

Machine Learning to Detect Cervical Spine Fractures Missed by Radiologists on CT: Analysis Using Seven Award-Winning Models from the RSNA 2022 Cervical Spine Fracture AI Challenge.

Available data on radiologists' missed cervical spine fractures are based primarily on studies using human reviewers to identify errors on re-evaluation; such studies do not capture the full extent of missed fractures. To use machine-learning (ML) models to identify cervical spine fractures on CT missed by interpreting radiologists, characterize the nature of these fractures, and assess their clinical significance. This retrospective study included all cervical spine CT examinations performed in adult patients in the emergency department between January 1, 2018 and December 31, 2022.
