Zechariah Aldāhirī's maqāma collection, Sefer hamusar , is a literary work modeled on the Arabic Maqāmāt of al-Harīrī and the Hebrew Tahkemoni of Alharizi. Although largely fictional in nature, the work offers intriguing evidence of the transmission of kabbalistic thought to Yemen in the sixteenth century. This paper argues that Aldāhirī exploited the text's lighthearted belletristic framework to bring kabbalistic theosophy, literature, and liturgical customs to the attention of a largely uninitiated public in Yemen. But Aldāhirī also conveys an ambivalence (...) towards his project when he parodies the new taste for kabbalistic learning by embedding mystical ideas in complex narratives. (shrink)

Why do humans make music? Theories of the evolution of musicality have focused mainly on the value of music for specific adaptive contexts such as mate selection, parental care, coalition signaling, and group cohesion. Synthesizing and extending previous proposals, we argue that social bonding is an overarching function that unifies all of these theories, and that musicality enabled social bonding at larger scales than grooming and other bonding mechanisms available in ancestral primate societies. We combine cross-disciplinary evidence from archeology, anthropology, (...) biology, musicology, psychology, and neuroscience into a unified framework that accounts for the biological and cultural evolution of music. We argue that the evolution of musicality involves gene–culture coevolution, through which proto-musical behaviors that initially arose and spread as cultural inventions had feedback effects on biological evolution because of their impact on social bonding. We emphasize the deep links between production, perception, prediction, and social reward arising from repetition, synchronization, and harmonization of rhythms and pitches, and summarize empirical evidence for these links at the levels of brain networks, physiological mechanisms, and behaviors across cultures and across species. Finally, we address potential criticisms and make testable predictions for future research, including neurobiological bases of musicality and relationships between human music, language, animal song, and other domains. The music and social bonding hypothesis provides the most comprehensive theory to date of the biological and cultural evolution of music. (shrink)

Pietraszewski proposes four triadic “primitives” for representing social groups. We argue that, despite surface differences, these triads can all be reduced to similar underlying welfare trade-off ratios, which are a better candidate for social group primitives. Welfare trade-off ratios also have limitations, however, and we suggest there are multiple computational strategies by which people recognize and reason about social groups.

Dispositional forgiveness is positively associated with many facets of wellbeing and has protective implications against depression and anxiety in adolescents. However, little work has been done to examine neurobiological aspects of forgiveness as they relate to clinical symptoms. In order to better understand the neural mechanisms supporting the protective role of forgiveness in adolescents, the current study examined the middle frontal gyrus, which comprises the majority of the dorsolateral prefrontal cortex and is associated with cognitive regulation, and its relationship to (...) forgiveness and clinical symptoms in a sample of healthy adolescents. In this cross-sectional study, larger MFG volume was significantly associated with higher self-reported dispositional forgiveness scores and lower levels of depressive and anxiety symptoms. Forgiveness mediated the relationship between MFG volume and both depressive and anxiety symptom levels. The mediating role of forgiveness in the relationship between MFG volume and clinical symptoms suggests that one way that cognitive regulation strategies supported by this brain region may improve adolescent mental health is via increasing a capacity for forgiveness. The present study highlights the relevance of forgiveness to neurobiology and their relevance to emotional health in adolescents. Future longitudinal studies should focus on the predictive quality of the relationship between forgiveness, brain volume and clinical symptoms and the effects of forgiveness interventions on these relationships.

We compare and contrast the 60 commentaries by 109 authors on the pair of target articles by Mehr et al. and ourselves. The commentators largely reject Mehr et al.'s fundamental definition of music and their attempts to refute (1) our social bonding hypothesis, (2) byproduct hypotheses, and (3) sexual selection hypotheses for the evolution of musicality. Instead, the commentators generally support our more inclusive proposal that social bonding and credible signaling mechanisms complement one another in explaining cooperation within and competition (...) between groups in a coevolutionary framework (albeit with some confusion regarding terminologies such as “byproduct” and “exaptation”). We discuss the proposed criticisms and extensions, with a focus on moving beyond adaptation/byproduct dichotomies and toward testing of cross-species, cross-cultural, and other empirical predictions.

Urban and agricultural communities are interdependent but often differ on approaches for improving water quality impaired by nutrient runoff waterbodies worldwide. Current water quality governance involves an overlapping array of policy tools implemented by governments, civil society organizations, and corporate supply chains. The choice of regulatory and voluntary tools is likely to influence many dimensions of the relationship between urban and agricultural actors. These relationships then influence future conditions for collective decision-making since many actors participate for multiple years in water (...) quality improvement. In this policy analysis, we draw on our professional experiences and research, as well as academic and practitioner literatures, to investigate how different types of water quality interventions influence urban-agricultural relationships, specifically examining policy tools on a regulatory to voluntary spectrum. Interactions between farmers and other rural agricultural interests on one hand, and urban residents and their stormwater managers and wastewater treatment plants on the other, influence dynamics relevant for water quality improvement. We suggest that the selection of policy tools within complex governance contexts influence urban–agricultural relationships through financial exchange, political coalitions, knowledge exchange, interpersonal relationships, and shared sense of place. Policy tools that provide a means to build relationships and engage with people’s emotions and identities have potential to influence personal and community change and adaptive capacity, while processes such as lawsuits can catalyze structural change. Engaging these relationships is particularly critical given the need to move out of polarized positions to solve collective problems. (shrink)

This case examines how IBERDROLA, Spain’s leading electricity supplier, shifted the company’s strategic focus to concentrate on sustainability and turned it into a source of competitive edge in a liberalized market. Largely pre-empting the industry obligations that came out of the Kyoto agreement, IBERDROLA decided to put sustainability at the heart of the company’s decision-making processes. IBERDROLA sold off its most polluting facilities and all non-core activities to concentrate on becoming the greenest player on the market. Its success was due (...) to its willingness to walk the talk, to get stakeholders on side, and to demonstrate its determination to be a corporate citizen. An important element of the strategy was to establish a working relationship with important NGOs and effect their involvement with IBERDROLA’s activities. An early and uneasy partnership with WWF/Adena over the production of green energy proved a sharp learning curve for both parties. Then in 2004 a relatively minor event triggered a chain of reactions that led to a revolution in the company’s policy of stakeholder integration. A small group of protected birds was killed when they flew into the blades at one of IBERDROLA’s wind power facilities. When previous similar crises had occurred, IBERDROLA had dealt with them through the time-honoured methods of dialogue and confrontation. This time, IBERDROLA decided to initiate a new approach. They invited SEO/BirdLife (the Spanish Ornithology Society), the oldest Spanish NGO dedicated to the environment, to undertake a study into the implications of similar installations on bird conservation and the environment. The intention is for this collaboration to lead to a strategic agreement between both parties. (shrink)
