The dorsal anterior cingulate cortex is a key node in the human salience network. It has been ascribed motor, pain-processing and affective functions. However, the dynamics of information flow in this complex region and how it responds to inputs remain unclear and are difficult to study using non-invasive electrophysiology. The area is targeted by neurosurgery to treat neuropathic pain. During deep brain stimulation surgery, we recorded local field potentials from this region in humans during a decision-making task requiring motor output. (...) We investigated the spatial and temporal distribution of information flow within the dACC. We demonstrate the existence of a distributed network within the anterior cingulate cortex where discrete nodes demonstrate directed communication following inputs. We show that this network anticipates and responds to the valence of feedback to actions. We further show that these network dynamics adapt following learning. Our results provide evidence for the integration of learning and the response to feedback in a key cognitive region. (shrink)

How well is the field of political studies doing and where is it headed? Such questions are examined and answered in this broad world overview of political science, along with the advances and shortcomings, as well as the recommended prescriptions for the future decades of the new century. The book includes three world regional assessments of the discipline, along with an in-depth survey of various sub-disciplinary fields and a concluding critical essay on the future of political studies. This is the (...) final volume in a book series on the development of political science, created in 2000 by Research Committee 33 of the International Political Science Association (IPSA) on the study of political science as a discipline. Contents include: Political Science in Three Asian Democracies: Disaffected (Japan), Third-Wave (Korea), and Fledgling (China) * Political Science in Europe: Its Development as a Discipline * Political Science in North America and Other Continents: Is There a Genuinely Int.

This anthology contains twelve papers on various aspects of Platonism, ranging from Plato's Republic to the Neoplatonism of Plotinus, Iamblichus, Proclus and Hermias, to the use of Platonic philosophy by Cudworth and Schleiermacher. The papers cover topics in ethics, psychology, religion, poetics, art, epistemology, and metaphysics.

Socializing Metaphysics supplies diverse answers to the basic questions of social metaphysics, from a broad array of voices. It will interest all philosophers and social scientists concerned with mind, action, or the foundations of social theory.

An analysis of student learning with the LISP tutor indicates that while LISP is complex, learning it is simple. The key to factoring out the complexity of LISP is to monitor the learning of the 500 productions in the LISP tutor which describe the programming skill. The learning of these productions follows the power‐law learning curve typical of skill acquisition. There is transfer from other programming experience to the extent that this programming experience involves the same productions. Subjects appear to (...) differ only on the general dimensions of how well they acquire the productions and how well they retain the productions. Instructional manipulations such as remediation, content of feedback, and timing of feedback are effective to the extent they give students more practice programming, and explain to students why correct solutions work.

This collection of recent articles by leading scholars is designed to illuminate one of the greatest and most influential philosophical books of all time. It includes incisive commentary on every major theme and argument in the Meditations, and will be valuable not only to philosophers but to historians, theologians, literary scholars, and interested general readers.

After responding to several misreadings of Milbank’s project in Theology and Social Theory—e. g., that it dispenses with “truth” or “reality”, is sectarian, reads a social theory off the Bible, is ecclesially absolutist—the authors highlight several strands of Milbank’s argument to stress the resolutely theological character of this work. In Milbank’s narrative, modernity is defined as a theological problem in which forms of modern secular thought have usurped theology as the “ultimate organizing logic”; his theological response to this involves a (...) broadly Augustinian account of the relationship between nature and grace which requires a theology which can only be true if it is enacted: it is necessary for the Church to make an actual historical difference in the world.

The technological breakthroughs and entrepreneurial adventures of Frank J. Sprague during the transformative years of the early electrical industry. Over the course of a little less than twenty years, inventor Frank J. Sprague achieved an astonishing series of technological breakthroughs--from pioneering work in self-governing motors to developing the first full-scale operational electric railway system--all while commercializing his inventions and promoting them to financial backers and the public. In Engineering Invention, Frederick Dalzell tells Sprague's story, setting it against the backdrop (...) of one of the most dynamic periods in the history of technology. In a burst of innovation during these years, Sprague and his contemporaries--Thomas Edison, Nicolas Tesla, Elmer Sperry, George Westinghouse, and others--transformed the technologies of electricity and reshaped modern life. After working briefly for Edison, Sprague started the Sprague Electric Railway and Motor Company; designed and built an electric railroad system for Richmond, Virginia; sold his company to Edison and went into the field of electric elevators; almost accidentally discovered a multiple-control system that could equip electric train systems for mass transit; started a third company to commercialize this; then sold this company to Edison and retired. Throughout his career, Dalzell tells us, Sprague framed technology as invention, cast himself as hero, and staged his technologies as dramas. He toiled against the odds, scraped together resources to found companies, bet those companies on technical feats--and pulled it off, multiple times. The idea of the "heroic inventor" is not, of course, the only way to frame the history of technology. Nevertheless, as Dalzell shows, Sprague, Edison, and others crafted the role consciously and actively, using it to generate vital impetus behind the process of innovation. (shrink)
