Local food systems are growing, and little is known about how the constellation of farms and markets change over time. We trace the evolution of two local food systems over six years, including a dataset of over 2690 market connections between 1520 locations. Longitudinal social network analysis reveals how the architecture, actor network centrality, magnitude, and spatiality of these supply chains shifted during the 2012–2018 time period. Our findings demonstrate that, despite growth in the number of farmers’ markets, grocery stores, (...) farms and restaurants in both counties, each local food system also experienced high turnover rates. Over 80% of the market connections changed during the study period. Farms, farmers’ markets, and grocery stores showed a 40–50% ‘survival’ rate, indicating their role in sustaining local food systems over longer time periods. Other actors, such as restaurants, had a much higher turnover rate within the network. Both food systems became more close-knit and consolidated as the center of gravity for both local food systems pulled away from urban areas toward rural farmland. Evidence of both growth and decay within local food systems provides a new understanding of the social networks behind local food markets. (shrink)

Mindfulness and compassion meditation are thought to cultivate prosocial behavior. However, the lack of diverse representation within both scientific and participant populations in contemplative neuroscience may limit generalizability and translation of prior findings. To address these issues, we propose a research framework calledIntersectional Neurosciencewhich adapts research procedures to be more inclusive of under-represented groups. Intersectional Neuroscience builds inclusive processes into research design using two main approaches: 1) community engagement with diverse participants, and 2) individualized multivariate neuroscience methods to accommodate neural (...) diversity. We tested the feasibility of this framework in partnership with a diverse U.S. meditation center (East Bay Meditation Center, Oakland, CA). Using focus group and community feedback, we adapted functional magnetic resonance imaging (fMRI) screening and recruitment procedures to be inclusive of participants from various under-represented groups, including racial and ethnic minorities, gender and sexual minorities, people with disabilities, neuropsychiatric disorders, and/or lower income. Using person-centered screening and study materials, we recruited and scanned 15 diverse meditators (80% racial/ethnic minorities, 53% gender and sexual minorities). The participants completed the EMBODY task – which applies individualized machine learning algorithms to fMRI data – to identify mental states during breath-focused meditation, a basic skill that stabilizes attention to support interoception and compassion. All 15 meditators’ unique brain patterns were recognized by machine learning algorithms significantly above chance levels. These individualized brain patterns were used to decode the internal focus of attention throughout a 10-min breath-focused meditation period, specific to each meditator. These data were used to compile individual-level attention profiles during meditation, such as the percentage time attending to the breath, mind wandering, or engaging in self-referential processing. This study provides feasibility of employing an intersectional neuroscience approach to include diverse participants and develop individualized neural metrics of meditation practice. Through inclusion of more under-represented groups while developing reciprocal partnerships, intersectional neuroscience turns the research process into an embodied form of social action. (shrink)

More than one third of the human brain is devoted to the processes of seeing - vision is after all the main way in which we gather information about the world. But human vision is a dynamic process during which the eyes continually sample the environment. Where most books on vision consider it as a passive activity, this book is unique in focusing on vision as an 'active' process. It goes beyond most accounts of vision where the focus is on (...) seeing, to provide an integrated account of seeing AND looking. The book starts by pointing out the weaknesses in our traditional approaches to vision and the reason we need this new approach. It then gives a thorough description of basic details of the visual and oculomotor systems necessary to understand active vision. The book goes on to show how this approach can give a new perspective on visual attention, and how the approach has progressed in the areas of visual orienting, reading, visual search, scene perception and neuropsychology. Finally, the book summarises progress by showing how this approach sheds new light on the old problem of how we maintain perception of a stable visual world. Written by two leading vision scientists, this book will be valuable for vision researchers and psychology students, from undergraduate level upwards. (shrink)

Two and a half thousand years ago Greek philosophers "looked up at the sky and formed a theory of everything." Though their solutions are little credited today, the questions remain fresh. Early Greek thinkers struggled to come to terms with and explain the totality of their surroundings, to identitify an original substance from which the universe was compounded, and to reconcile the presence of balance and proportion with the apparent disorder of the cosmos. M. R. Wright examines cosmological theories of (...) the "natural philosophers" from Thales, Anaximander and Anaximenes to Plato, the Stoics and the NeoPlatonists. The importance of Babylonian and Egyptian forerunners is also emphasized. Cosmology in Antiquity is a comprehensive introduction to the cosmological thought in ancient times. (shrink)

I argue on the basis of extensive empirical research that perception and emotion are more deeply entangled than we might have thought. This evidence strongly suggests that we should expand our conception of perception to include emotional elements, and our conception of emotion to include perceptual ones. This expansion poses a challenge to our current taxonomic practices. In the face of this challenge, I advocate principled pluralism about psychological kinds. This view holds that, depending on our explanatory purposes, psychological processes (...) can be legitimately classified in more than one way. (shrink)

The considerable attention to financial interests in clinical research has focused mostly on academic medical centers, even though the majority of clinical research is conducted in community practice settings. To fill this gap, this article maps the practices and policies in 73 community hospitals and several hundred specialized facilities around the country for reviewing clinical investigators’ financial relationships with research sponsors. Community hospitals face a substantially different mix of issues than academic medical centers do because their physician researchers are usually (...) not employees, and more of their studies are later-phase, multicenter trials. Accordingly, community physicians stand to benefit personally from per capita payments, but they tend to have less direct influence over research findings when compared with their academic peers. These and other contrasts require separate guidance for community-based organizations that takes into account their particular needs, circumstances, and institutional capacities. (shrink)

David Hume was a highly original thinker. Nevertheless, he was a writer of his time and place in the history of philosophy. In this book, M. A. Stewart puts Hume’s writing in context, particularly that of his native Scotland, but also that of British and European philosophy more generally. Through meticulous research Stewart brings to life the circumstances by means of which we can get a deeper understanding of Hume’s writings on the nature and reach of human reason, the foundation (...) of morals, and, especially, on the philosophy of religion. Stewart pays particular attention to Hume’s intellectual development, beginning with his education at the College of Edinburgh, the writing of his Treatise of Human Nature, and his subsequent philosophical responses to criticisms of that book. He argues that Hume’s scepticism set him at odds with the Christian Stoicism of Scottish contemporaries including that of Francis Hutcheson - and shows that this conflict played a major role in his failure to obtain the Edinburgh Moral Philosophy Chair in 1745. Stewart’s detailed study of the physical character of Hume’s surviving manuscripts in Chapters 8 and 9 provides the best available dating of his early ‘Essay on Modern Chivalry’, his ‘Early Fragment on Evil’ and the periods of composition of his Dialogues Concerning Natural Religion. Other chapters compare Hume’s theory of abstraction with that of Locke and Berkeley, provide the 17th and 18th century philosophical context of the central argument of his essay ‘Of miracles’, and consider the 18th and 19th century reception of his writings in England and Ireland.
