Color perception and attentional load in dynamic, time-constrained environments

The capacity to perceive color in the peripheral field has attracted research interest for more than a decade. There is evidence that sensitivity to red-green color variations is lower than for yellow-blue in peripheral vision. Whether, and to what extent, color vision affects the visual focus of attention, which is normally much smaller than the visual field, has not yet been examined. We used a sport-specific decision-making task to assess whether the color of the jersey worn by players appearing in the periphery influences decision making by affecting the attentional and perceptual capabilities. Pairs of players wearing chromatic (blue, yellow, red, and green) and achromatic (black, white) colored jerseys were briefly presented across a range of visual angles on a 6 m concave immersive screen. Participants were required to decide to whom to pass and recall relevant information. Findings indicate that color perception changes vary with increasing visual angle, but that the focus of attention is too small to be influenced by jersey color sensitivity. Decision-making performance decreases with increasing visual angle, but is not influenced by color. The implications for decision-making processes in sport and other professional domains are discussed

Engineering Cloud-based Applications: Towards an Application Lifecycle

The adoption of cloud computing by organizations of all sizes and types in the recent years has created multiple opportunities and challenges for the development of software to be used in this environment. In this work-in-progress paper, the focus is on the latter part, providing a view on the main research challenges that are created for software engineering by cloud computing. These challenges stem from the inherent characteristics of the cloud computing paradigm, and require a multi-dimensional approach to address them. Towards this goal, a lifecycle for cloud-based applications is presented, as the foundation for further work in the area

Situation, Figuration und Gewalt. Versuch eines gewaltsoziologischen Dialoges zwischen Randall Collins und Norbert Elias am Beispiel sexueller Kriegsgewalt

Ebner J, Stopfinger M. Situation, Figuration und Gewalt. Versuch eines gewaltsoziologischen Dialoges zwischen Randall Collins und Norbert Elias am Beispiel sexueller Kriegsgewalt. Österreichische Zeitschrift für Soziologie. 2020;45(S1):43-67.In diesem Beitrag werden zwei in der soziologischen Gewaltforschung etablierte Ansätze – die mikrosoziologisch-situationistische Gewalttheorie von Randall Collins und die figurations- bzw. prozesssoziologische Perspektive von Norbert Elias – auf ihre Eignung für die Analyse von sexueller Kriegsgewalt überprüft. Nach einer kurzen Diskussion des Forschungsstandes zu sexueller Kriegsgewalt wird dieses Thema einmal mit Collins und einmal mit Elias beleuchtet. Danach werden die beiden Zugänge einander gegenübergestellt, um Unterschiede und Gemeinsamkeiten herauszuarbeiten. Darauf aufbauend wird versucht, die Fruchtbarkeit eines „pragmatischen Dialoges“ zwischen einem mikro- und einem figurationssoziologisch inspirierten Ansatz auszuloten. Abschließend wird diskutiert, welche Folgerungen sich daraus für die Forschung zu sexueller Kriegsgewalt ergeben.In this paper, two approaches established in sociological violence research – Randall Collins’ micro-sociological theory of violence and Norbert Elias’ figuration- and process-sociological perspective—are examined for their suitability for the analysis of sexual violence in war. After a brief discussion of the current state of research on sexual violence in war, this topic will be examined once with Collins and once with Elias. The two approaches are then juxtaposed in order to highlight differences and similarities. Building on this, the fruitfulness of a “pragmatic dialogue” between a micro- and a figuration-sociologically inspired approach will be explored. The concluding section discusses the implications for research on sexual violence in war
