The dyeing behavior of conventional false-twist pin-textured polyester yarns has been studied as a function of the texturing variables. Three different dyes and three different dyeing procedures were employed. The data obtained are discussed in relation to existing quality-control procedures for textured yarns and the role of feed-yarn non-uniformity in barré problems.

The effect of tension in the winding zone of the false-twist-texturing process on the crimp properties of textured polyethylene terephthalate yarn has been investigated. It was found that, all other conditions remaining unchanged, high wind-up tension results in low crimp retraction. Post-texturing treatments enhance the crimp retraction of these yarns and demonstrate the role of wind-up tension in rendering the crimp latent.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.

Abstract Tomasello offers a compelling account of the emergence of humans’ sense of obligation. We suggest that more needs to be said about the role of affect in the creation of obligations. We also argue that positive emotions such as gratitude evolved to encourage individuals to fulfill cooperative obligations without the negative quality that Tomasello proposes is inherent in obligations.

Abstract The authors do the field of cultural evolution a service by exploring the role of non-social cognition in human cumulative technological culture, truly neglected in comparison with socio-cognitive abilities frequently assumed to be the primary drivers. Some specifics of their delineation of the critical factors are problematic, however. I highlight recent chimpanzee–human comparative findings that should help refine such analyses.
