Rising energy costs, increasing herd sizes, and other structural changes affecting the New York dairy industry may make farmers receptive to new energy production technologies. Anaerobic digestion represents a possible benefit to farmers by reducing odor while producing methane for electricity. However, current digester designs are for herd sizes of 300 or more cows, with significant economies of scale, so smaller operators may have little interest in the technology. Moreover, without a favorable policy environment and reliable grant programs, the initial (...) investments required for digester installation might deter operators. One solution to these issues may be community digesters, which are centrally located facilities that accept manure from multiple farms. Data from a survey of New York dairy farmers were used to assess farmers’ interest in community digesters. In general, interest was associated with power generation outcomes and reservations about organic farming practices; advocates might encourage their use among smaller conventional farm operators looking for new sources of profit and diversification.

In this address I examine the challenges of achieving food system sustainability. Starting from the position that most people want a food system that is “sustainable” and that we have a great reservoir of unapplied technical knowledge applicable to increasing sustainability, I argue that the big issue is collective decision-making to accomplish the goal of sustainability. Using the metaphor of a sailing ship, I raise three questions about steering collectively toward sustainability: What do we want? What are our options? And, (...) how do we decide among the options?

A paradigm shift in public health and medicine has broadened the field from a singular focus on the ill effects of negative states and psychopathology to an expanded view that examines protective psychological assets that may promote improved physical health and longevity. We summarize recent evidence of the link between psychological well-being and physical health, with particular attention to outcomes of mortality and chronic disease incidence and progression. Within this evolving discipline there remain controversies and lessons to be learned. We (...) discuss measurement-related challenges, concerns about the quality of the evidence, and other shortcomings in the field, along with a brief discussion of hypothesized biobehavioral mechanisms involved. Finally, we suggest next steps to move the field forward. (shrink)

This reply addresses observations of Drs. Larsen, Kruse, and Sweeny, and Scherer in their reviews of our published work on the link between positive psychological assets and outcomes of physical health. Inspired by Obama’s Precision Medicine Initiative we argue that the interplay between the emotion spectrum and health is likely a complex and heterogeneous amalgam of known and yet unidentified elements melding at the individual level. When exploring the emotion–health link, researchers are challenged to grapple with complex system models by (...) considering multiple hierarchies of information that span individual-level factors, genetic blueprints, and cultural and environmental context. Research is needed to more fully elucidate the mechanism through which emotion influences health, with careful consideration of differences across race/ethnicity, culture, and context. (shrink)

Canon law has an abiding purpose in the Church: to aid in the creation of a community that is a true sign of the fellowship of love.

Multilevel research strategies characterize contemporary molecular inquiry into biological systems. We outline conceptual, methodological, and explanatory dimensions of these multilevel strategies in microbial ecology, systems biology, protein research, and developmental biology. This review of emerging lines of inquiry in these fields suggests that multilevel research in molecular life sciences has significant implications for philosophical understandings of explanation, modeling, and representation.
