The λ model suggests that detailed kinematics arise from changes in control variables and need not be explicitly planned. However, we have shown that when moving a grasped object, grip force is precisely modulated in phase with acceleration-dependent inertial load. This suggests that the motor system can predict detailed kinematics. This prediction may be based on a forward model of the dynamics of the loaded limb.

Interdisciplinarity is a notoriously difficult concept to define, and even harder to achieve in practice. All too often social approaches reduce science to an object of study, or conversely physical science approaches are invoked as a source of 'higher' truth. Drawing upon our experiences as ESRC-NERC PhD students within geography, we outline a paratactical approach that links disciplines by adjacency rather than hierarchy. Toppling the disciplinary hierarchy creates the potential for non-reductionistic dialogue between science and social science, but it also (...) raises a series of practical difficulties. These are considered around the themes of polyvocality, breadth over depth and (im)permanence. We suggest that while this kind of approach is increasingly encouraged by research funding bodies, it is less easily sustained within the everyday mechanics of the academic world.

Piron's axioms for a realistically interpreted quantum mechanics are analyzed in detail within the context of a formal mathematical structure expressed in the conventional set-theoretic idiom of mathematics. As a result, some of the serious misconceptions that have encouraged recent criticisms of Piron's axioms are exposed.

RationaleSurrogates of critically ill patients often have inaccurate expectations about prognosis. Yet there is little research on how intensive care unit clinicians should discuss prognosis, and existing expert opinion-based recommendations give only general guidance that has not been validated with surrogate decision makers.ObjectiveTo determine the perspectives of key stakeholders regarding how prognostic information should be conveyed in critical illness.MethodsThis was a multicenter study at three academic medical centers in California, Pennsylvania, and Washington. One hundred eighteen key stakeholders completed in-depth semistructured (...) interviews. Participants included 47 surrogates of adult patients with acute respiratory distress syndrome; 45 clinicians working in study ICUs, including physicians, nurses, social workers, and spiritual care providers; and 26 experts in health communication, decision science, ethics, family-centered care, geriatrics, healthcare disparities, palliative care, psychology, psychiatry, and critical care.Measurements and main resultsThere was broad support among surrogates for existing expert recommendations, including truthful prognostic disclosure, emotional support, tailoring the disclosure strategy to each family's needs, and checking for understanding. In addition, stakeholders offered suggestions that add specificity to existing recommendations, including: In addition to conveying prognostic estimates, clinicians should help families "see the prognosis for themselves" by showing families radiographic images and explaining the clinical significance of physical manifestations of severe disease at the bedside. Many physicians did not support using numeric estimates to convey prognosis to families, whereas many surrogates, clinicians from other disciplines, and experts believed numbers could be helpful. Clinicians should conceptualize prognostic communication as an iterative process that begins with a preliminary mention of the possibility of death early in the ICU stay and becomes more detailed as the clinical situation develops. Although prognostic information should be initially disclosed by physicians, other members of the multidisciplinary team-nurses, social workers, and spiritual care providers-should be given explicit role responsibilities to reinforce physicians' prognostications and help families process a poor prognosis emotionally.ConclusionsFamily members, clinicians, and experts identified specific communication behaviors that clinicians should use to discuss prognosis in the critical care setting. These findings extend existing opinion-based recommendations and should guide interventions to improve communication about prognosis in ICUs. (shrink)

Forest tenure reforms are occurring in many developing countries around the world. These reforms typically include devolution of forest lands to local people and communities, which has attracted a great deal of attention and interest. While the nature and level of devolution vary by country, all have potentially important implications for resource allocation, local ecosystem services, livelihoods and climate change. This book helps students, researchers and professionals to understand the importance and implications of these reforms for local environmental quality, climate (...) change, and the livelihoods of villagers, who are often poor. It is shown that local forest management can often be more successful than top-down management of common pool forest resources. The relationship of local forest tenure reform to the important climate change initiative REDD+ is also considered. The work includes a number of generic chapters and also detailed case studies from China, Ethiopia, Kenya, Nepal, Tanzania and Uganda. Using specific examples and a wide variety of disciplinary perspectives, including quantitative and qualitative analytical methods, the book provides an authoritative and critical picture of local forest reforms in light of the key challenges humanity faces today.

Until recently, it was widely assumed in societies with long-established, publicly funded school systems that school attendance served the interests of children, society, and parents alike. In the United States and other common-law jurisdictions, safeguarding and promoting the independent welfare and developmental interests of every child was a public responsibility under the parens patriae doctrine. Compulsory schooling laws enacted under parens patriae authority required all persons having care and control of a child to share their custodial authority with publicly certified (...) teachers for limited periods of time. By compelling all parents to send their children to school, the state ensured that all children had access to instruction and opportunities for social, economic, and civic participation beyond what their parents alone could provide. Parents were incidentally freer to manage the competing demands of domestic life and paid employment, and the enforcement of child labor laws was greatly facilitated by efforts to ensure school attendance. While compulsory schooling laws imposed obvious limits on the custodial authority of all parents for the sake of all children, they were rarely challenged on that basis. Not so today. (shrink)

This essay examines the doctrine of divine omnipresence. I begin by presenting three desiderata for an adequate account of omnipresence. Four accounts are analyzed in light of these desiderata, two in the tradition and two in contemporary philosophical theology. I argue that none succeed in providing an adequate account of divine omnipresence. As an alternative, I offer a paradoxical account of omnipresence, arguing that one can be rational in affirming that what appears to be a doctrine afflicted by apparent contradiction (...) is in fact merely a paradox. I explain what makes affirmations of paradoxical doctrines rational, why omnipresence should be understood as a paradox, and discuss a similar account of omnipresence in the writings of Pseudo-Dionysius the Areopagite.

This paper explores the relationship between early modern English Puritanism and Reformed orthodoxy through a fresh examination of three ministers who have been described as Puritans: John Owen, Richard Baxter, and John Goodwin. By assessing their attitudes toward the Bible and specifically the doctrine of justification, this paper uncovers an evolving consensus of orthodox thought in the period. Their attitudes and approaches to doctrine and church tradition led to diverse interpretations and directions in the codification of their religion. Their theological (...) interpretations reflect an inherent pattern of diversity within English Puritanism, especially in its attitudes towards the formation of orthodoxy. The relation of Reformed orthodoxy to Puritanism, then, is more complex than older modes of scholarship have allowed. For the Puritan mainstream, Reformed orthodoxy served as a theological compass and thermostat that tested ideas and was to govern both the direction and temperament of Reformed doctrine. For those outside the pale, such orthodoxy and their alleged disloyalty to the Bible and Reformed church tradition was vehemently contested. (shrink)

In orthodox quantum mechanics, it has virtually become the custom to identify properties of a physical system with operationally testable propositions about the system. The causes and consequences of this practice are explored mathematically in this paper. Among other things, it is found that such an identification imposes severe constraints on the admissible states of the physical system.
