The temperature dependences of the positron annihilation lifetime and Doppler broadening have been measured in the Bi-Sr-Ca-Cu-O superconducting system from 77 to 300 K. The results show the existence of two superconducting phases: Tc=90 K 2212 phase and Tc=107 K 2223 phase, with the latter being dominant. Two anomalies were detected around 145 and 250 K, respectively. The role of long-time sintering and adding Pb and Nb in Bi-Sr-Ca-Cu-O is demonstrated in stabilizing the 2223 phase.

The phase diagram of the ternary intermetallics CeMIn5 (M = Co, Rh, In) presents new forms of competition and coexistence between magnetic and superconducting phases. We briefly review the experiments that have outlined the temperature-pressure phase diagram of these materials, emphasizing the phenomenon of reversible tuning. Expanding a recently proposed model for the coexistence of antiferromagnetism and superconductivity, we study the role of electronic doping on the ordering temperatures of these phases.

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.

Sense Of Obligation

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.
