Perturbed matrix theory is applied to the calculation of the position, intensity, and polarization of the absorption band due to an impurity in a crystal. Many practical approximations are derived. Especial emphasis is laid on the role of the second moment, S, of the host's exciton band, a quantity experimentally determinable. The approximations are compared with the exact results of model calculations for which naphthalene was taken as host crystal. The theory is applied with success to the spectra of isotopically impure naphthalene (first singlet transition, S(0) = 1400cm-2 and benzene (3B1u, S(0) = 700cm-2 S(0) is the second moment of the exciton band at the transition origin, and is related to S by a Franck-Condon factor.

This article addresses the role of the design professions in enhancing seismic safety as evidenced by interviews with design professionals in the Pacific Northwest. Key policy issues of relevance to this discussion concern the role of codes and other regulatory efforts in influencing design practices. The findings indicate seismic design practices are driven by seismic codes and related norms of “good” engineering and seismic design. Economic and liability considerations constrain practices beyond those of code provisions. As a consequence, policy reforms for seismic risk reduction are highly dependent upon seismic code revision. Variation in seismic design practice is reduced through professional educational efforts, professional licensing and registration requirements, and code enforcement. These findings serve as qualified endorsement of the current federal “limited regulatory” strategy in working with private code-setting authorities to improve seismic code provisions. The qualifications concern the disjunctive impacts of the limited regulatory strategy.

The Carolingian conquest of Lombard Italy (774) was preceded by a massive effort on the part of the Church to convince the Frankish court of the legitimacy of the invasion. Relying on a terminology borrowed from Gregory I, the papal court produced an offensive portrait of the Lombards, depicted as treacherous, vile, and heathen. This article analyzes eighth-century papal epistolary and the Liber Pontificalis in order to establish the strategies behind this campaign. In a second moment, we turn to the Lombard response after the conquest, and the efforts of Paul the Deacon as well as the anonymous author of the Origo Langobardorum codicis Gothanis to question the papal portrait of the Lombards and to reclaim the Christian past of their people. Both Paul and the Gotha Origo focused on the importance of the conversion — and especially the role of Gregory the Great — in the rehabilitation of the Lombards. Their works, this article suggests, represent an attempt of the Lombards to dissociate their Christian faith from the conquest and to reclaim the narrative about their own past.

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.
