Safe stair negotiation is an everyday task that children with developmental coordination disorder are commonly thought to struggle with. Yet, there is currently a paucity of research supporting these claims. We investigated the visuomotor control strategies underpinning stair negotiation in children with and without DCD by measuring kinematics, gaze behavior and state anxiety as they ascended and descended a staircase. A questionnaire was administered to determine parents' confidence in their child's ability to safely navigate stairs and their child's fall history. (...) Kinematics were measured using three-dimensional motion capture, whilst gaze was measured using mobile eye-tracking equipment. The parents of DCD children reported significantly lower confidence in their child's ability to maintain balance on the stairs and significantly more stair-related falls in the previous year compared to the parents of typically developing children. During both stair ascent and stair descent, the children with DCD took longer to ascend/descend the staircase and displayed greater handrail use, reflecting a more cautious stair negotiation strategy. No differences were observed between groups in their margin of stability, but the DCD children exhibited significantly greater variability in their foot-clearances over the step edge, which may increase the risk of a fall. For stair descent only, the DCD children reported significantly higher levels of state anxiety than the TD children and looked significantly further along the staircase during the initial entry phase, suggesting an anxiety-related response that may bias gaze toward the planning of future stepping actions over the accurate execution of an ongoing step. Taken together, our findings provide the first quantifiable evidence that safe stair negotiation is a significant challenge for children with DCD, and that this challenge is reflected by marked differences in their visuomotor control strategies and state anxiety levels. Whilst it is currently unclear whether these differences are contributing to the frequency of stair-related falls in children with DCD, our findings pave the way for future research to answer these important questions.

This book's importance is derived from three sources: careful conceptualization of teacher induction from historical, methodological, and international perspectives; systematic reviews of research literature relevant to various aspects of teacher induction including its social, cultural, and political contexts, program components and forms, and the range of its effects; substantial empirical studies on the important issues of teacher induction with different kinds of methodologies that exemplify future directions and approaches to the research in teacher induction.

Interpretation of the classics in political theory seems to go in waves. For a while we had John Locke, the bourgeois thinker. Now we seem to be in a Locke-as-radical-democrat phase. Locke-the-bourgeois had problems of its own, but a radically democratic Locke -- not just the old Locke as liberal democrat but Locke as quasi-Leveller -- strains the interpretative imagination more than most; yet in recent years, several different kinds of argument have been advanced in support of it, both textual (...) and contextual. The most effective argument has proceeded by situating Locke in the context of radical Whig politics in the 1670s and '80s, the struggles over religious toleration and the royal succession, in particular the �Exclusion Crisis� of 1679-81. This contextual argument has been accompanied by various textual interpretations having to do with Locke's conceptions of property, consent, representation, the right of revolution and natural law. Among other things, these are supposed to show that while Locke had nothing explicit to say about the extent of the franchise, the weight of evidence suggests that he would have supported a fairly wide franchise, perhaps even something like the (almost) manhood suffrage advocated by the Levellers (at least according to some, and probably the most convincing, interpretations of their ideas). Most recently, in these pages, Martin Hughes, building on the work of James Tully and Richard Ashcraft in particular, has pushed the argument as far as it can probably go. His argument on taxation and suffrage has provided a motivation here for a wider exploration of Locke's views on representation, consent and the franchise. (shrink)

This essay, as the title suggests, is not just a reply to Richard Ashcraft -- although it is certainly that too. Its intention is to say something about the political theory of Locke, about his historical context and about the methodological question of contexts in general. About his political theory, I want to make two or three main points which, I think, have important consequences for our understanding of Locke: that he both appropriates and, on critical issues, deliberately neutralizes (...) the radical �discourses� of his time -- so that, for example, he adopts Leveller premises to arrive at something more like Cromwell's (or even more conservative) conclusions; and that he deprives these radical discourses of their most democratic implications less by excluding people from membership in the political nation than by restricting the rights of membership itself. This means, among other things, that the relevant debate is not the one that has so preoccupied Locke scholars -- namely, the controversy about who is a �freeman� or who belongs to the �people�. The decisive question is rather what political rights the �people� have. (shrink)

Aristotle’s On generation and corruption raises a vital question: how is mixture, or what we would now call chemical combination, possible? It also offers an outline of a solution to the problem and a set of criteria that a successful solution must meet. Understanding Aristotle’s solution and developing a viable peripatetic theory of chemical combination has been a source of controversy over the last two millennia. We describe seven criteria a peripatetic theory of mixture must satisfy: uniformity, recoverability, potentiality, equilibrium, (...) alteration, incompleteness, and the ability to distinguish mixture from generation, corruption, juxtaposition, augmentation, and alteration. After surveying the theories of Philoponus , Avicenna , Averroes , and John M. Cooper , we argue for the merits of Richard Rufus of Cornwall’s theory. Rufus was a little known scholastic philosopher who became a Franciscan theologian in 1238, after teaching Aristotelian natural philosophy as a secular master in Paris. Lecturing on Aristotle’s De generatione et corruptione, around the year 1235, he offered his students a solution to the problem of mixture that we believe satisfies Aristotle’s seven criteria.Author Keywords: Mixture; Mixt; Chemical combination; Accidental potential; Potential; Elements; Medieval chemistry; Peripatetic chemistry; Aristotelian science; Richardus Rufus; Averroes ; Avicenna ; Philoponus ; John M.

Dubbed “Nietzsche without his hammer” by literary critic James Wood, the Romanian philosopher E. M. Cioran is known as much for his profound pessimism and fatalistic approach as for the lyrical, raging prose with which he communicates them. Unlike many of his other works, such as _On the Heights of Despair_ and _Tears and Saints_, _The New Gods_ eschews his usual aphoristic approach in favor of more extensive and analytic essays. Returning to many of Cioran’s favorite themes, _The New (...) Gods _explores humanity’s attachment to gods, death, fear, and infirmity, in essays that vary widely in form and approach. In “Paleontology” Cioran describes a visit to a museum, finding the relatively pedestrian destination rife with decay, death, and human weakness. In another chapter, Cioran explores suicide in shorter, impressionistic bursts, while “The Demiurge” is a shambolic exploration of man’s relationship with good, evil, and God. All the while, _The New Gods _reaffirms Cioran’s belief in “lucid despair,” and his own signature mixture of pessimism and skepticism in language that never fails to be a pleasure. Perhaps his prose itself is an argument against Cioran’s near-nihilism: there is beauty in his books. (shrink)

Ethics and the Clinical Encounter explores the moral dimensions of clinical medicine and the phenomenon of illness, to determine what ethics must be in order to be fully responsive to clinical encounters. Written in a lively and conversational style with minimal technical terminology, and enhanced by actual experience or real clinical situations, this volume lays out a clinical ethics methodology both in practical and theoretical terms. Here's what the experts had to say: Professor Zaner has provided us with a remarkably (...) lucid and trenchant discussion of the interface of philosophy and the field of medicine. He brings into play an extraordinary range of historial knowledge, extensive observations based on firsthand experience with medical practices, and an acute sense of philosophical argumentation. This is a work that will be an exemplary and indispensable text in the philosophy of medicine for years to come. -- Calvin Schrag... it is a highly original contribution usable in a number of fields.... It really has no competition.... The genius of Zaner's approach is to ground ethics from the 'bottom up' and to direct us to the concrete particulars of therapeutic encounters wherein lie moral and ethical matters... meaty, challenging, and ultimately rewarding.... -- Paul R. Dokecki Richard M. Zaner founded the Center for Clinical and Research Ethics at Vanderbilt University Medical Center. Having established Vanderbilt's first Hospital Ethics Committee (1985), he served as co-chair of VUMC's Ethics Committee since its inception in 1990. Zaner has published five original books, edited ten, and translated four more, and has published more than 100 sections of books and professional journals. (shrink)

Early in the first volume of his Ideen zu einer reinen Phiinomeno logie und phiinomenologischen Philosophie, Edmund Husserl stated concisely the significance and scope of the problem with which this present study is concerned. When we reflect on how it is that consciousness, which is itself absolute in relation to the world, can yet take on the character of transcendence, how it can become mundanized, We see straightaway that it can do that only by means of a certain participation in (...) transcendence in the first, originary sense, which is manifestly the transcendence of material Nature. Only by means of the experiential relation to the animate organism does consciousness become really human and animal (tierischen), and only thereby does it achieve a place in the space and in the time of Nature. l Consciousness can become "worldly" only by being embodied within the world as part of it. In so far as the world is material Nature, consciousness must partake of the transcendence of material Nature. That is to say, its transcendence is manifestly an embodiment in a material, corporeal body. Consciousness, thus, takes on the characteristic of being "here and now" (ecceity) by means of experiential (or, more accurately, its intentive) relation to that corporeal being which embodies it. Accordingly, that there is a world for consciousness is a conse quence in the first instance of its embodiment by 2 that corporeal body which is for it its own animate organism. (shrink)

Tested the 2-process theory of detection, search, and attention presented by the current authors in a series of experiments. The studies demonstrate the qualitative difference between 2 modes of information processing: automatic detection and controlled search; trace the course of the learning of automatic detection, of categories, and of automatic-attention responses; and show the dependence of automatic detection on attending responses and demonstrate how such responses interrupt controlled processing and interfere with the focusing of attention. The learning of categories is (...) shown to improve controlled search performance. A general framework for human information processing is proposed. The framework emphasizes the roles of automatic and controlled processing. The theory is compared to and contrasted with extant models of search and attention. (shrink)

This honest, forthright, and beautifully-written book introduces readers to the human variations on medical topics spoken of in abstract in the daily news--euthanasia, assisted suicide, abortion, "extreme procedures", genetic testing, experimental surgeries--and to the people who must agonize over those decisions regarding themselves and their loved ones.

This article reviews the historical and current controversies about the nature of clinical ethics consultation, as a way to focus on the place and responsibility of ethics consultants within the context of clinical conversation — interpreted as a form of dialogue. These matters are approached through a particularly compelling instance of the controversy that involves several major figures in the field. The analysis serves to highlight very significant questions of the nature and constraints of clinical situations, and the moral responsibility (...) and legal accountability that are especially important for clinical ethics consultants.

I agree with Norris et al. that feedback to a phonemic level is never necessary, but disagree strongly with their reason why this is true. I believe the available evidence indicates that there is no feedback because there is no phonemic level employed in the perceptual processing of speech.

The target article suggests that taste is not based on the traditional four basic tastes, but rather is a continuum subserved by cross-fiber integration. This commentary describes evidence indicating that the traditional concept is valid, and that with suitable precautions, it is possible to match natural substances using mixtures representing fundamental tastes.

After writing my response to the commentaries, I sat back and reflected on the fascination and frustration of work on this topic. There is the ancient fascination of trying to understand the nature of the sensory bridge linking us to the external world. Also, discussing the measurability of sensation brings to the surface concepts we use and take for granted when we are working in other areas of psychology; and it holds them before us for critical examination. The frustration lies (...) chiefly in the difficulty of formulating concepts clearly, in a way understood by all. At least when constructing the original Tower of Babel, workers hearing strange words knew that communication was not occurring. The psychophysical Tower of Babel sometimes has workers using the same words, but with different meanings. Much of my response is based on attempts to clarify concepts and clear up confusions.

Block has attempted to reduce the confusion and controversy concerning the term “consciousness” by suggesting that there are two forms or types of consciousness, each of which has several characteristics or properties. This suggestion appears to further becloud the topic, however. Perhaps consciousness cannot be defined adequately and should not be considered as a topic that can be studied scientifically.

This paper is devoted to an examination of the discovery, characterization, and analysis of the functions of microRNAs, which also serves as a vehicle for demonstrating the importance of exploratory experimentation in current (post-genomic) molecular biology. The material on microRNAs is important in its own right: it provides important insight into the extreme complexity of regulatory networks involving components made of DNA, RNA, and protein. These networks play a central role in regulating development of multicellular organisms and illustrate the importance (...) of epigenetic as well as genetic systems in evolution and development. The examination of these matters yields principled arguments for the historicity of the functions of key biological molecules and for the indispensability of exploratory experimentation in contemporary molecular biology as well as some insight into the complex interplay between exploratory experimentation and hypothesis-driven science. This latter result is not only important for philosophy of science, but also of practical importance for the evaluation of grant proposals, although the elaboration of this latter claim must be left for another occasion.

There has been in recent years a plethora of defences of theism from analytical philosophers: Richard Gale's important book is a critical response to these writings. New versions of cosmological, ontological, and religious experience arguments are critically evaluated, along with pragmatic arguments to justify faith on the grounds of its prudential or moral benefits. In considering arguments for and against the existence of God, Gale is able to clarify many important philosophical concepts including exploration, time, free will, personhood, actuality, (...) and the objectivity of experience.

History of science, it has been argued, has benefited philosophers of science primarily by forcing them into greater contact with "real science." In this paper I argue that additional major benefits arise from the importance of specifically historical considerations within philosophy of science. Loci for specifically historical investigations include: (1) making and evaluating rational reconstructions of particular theories and explanations, (2) estimating the degree of support earned by particular theories and theoretical claims, and (3) evaluating proposed philosophical norms for the (...) evaluation of the degree of support for theories and the worth of explanations. More generally, I argue that theories develop and change structure with time, that (like biological species) they are historical entities. Accordingly, both the identification and the evaluation of theories are essentially historical in character. (shrink)

The measurement of sensory intensity has had a long history, attracting the attention of investigators from many disciplines including physiology, psychology, physics, mathematics, philosophy, and even chemistry. While there has been a continuing doubt by some that sensation has the properties necessary for measurement, experiments designed to obtain estimates of sensory intensity have found that a general rule applies: Equal stimulus ratios produce equal sensory ratios. Theories concerning the basis for this simple psychophysical rule are discussed, with emphasis given to (...) the physical correlate theory, which considers judgments of subjective magnitudes to be based upon estimates of physical dimensions that vary regularly with changes in degree of stimulation. For the most thoroughly investigated sensory scales, brightness and loudness, the physical correlate is considered to be distance. Our “tacit knowledge” of the sensory effects of changing distance plays an essential role in matching motor activities to environmental conditions and in ensuring accurate perceptual evaluations through brightness and loudness constancies. In psychophysical experiments, subjects apparently use this same tacit knowledge when required to estimate relative subjective magnitudes. The evidence related to the physical correlate theory is summarized, and it is concluded that, while under appropriate conditions we demonstrate considerable skill in evaluating environmental relationships, we are quite unable to estimate the neurophysiological nature or quantity of sensory response. A psychophysics devoted to studying conditions required for accuracy and conditions producing errors in the perception of environmental relationships would seem to be more valuable than one devoted to subjective magnitudes.

We will give a new cosmological argument for the existence of a being who, although not proved to be the absolutely perfect God of the great Medieval theists, also is capable of playing the role in the lives of working theists of a being that is a suitable object of worship, adoration, love, respect, and obedience. Unlike the absolutely perfect God, the God whose necessary existence is established by our argument will not be shown to essentially have the divine perfections (...) of omnipotence, omniscience, omnibenevolence, and sovereignty. Furthermore, it is not even shown that he is contingently omnipotent and omniscient, just powerful and intelligent enough to be the supernatural designer-creator of the exceedingly complex and wondrous cosmos that in fact..

Abstract:In this article we first review the development of the concept of global business citizenship and show how the libertarian political philosophy of free-market capitalism must give way to a communitarian view in order for the voluntaristic, local notion of “corporate citizenship” to take root. We then distinguish the concept of global business citizenship from “corporate citizenship” by showing how the former concept requires a transition from communitarian thinking to a position of universal human rights. In addition, we link global (...) business citizenship to global business strategy and to three analytical levels of ethical norms. Finally, we trace a process whereby global businesses can implement fundamental norms and learn to accommodate to legitimate cultural differences. (shrink)

In an overview of the essays in this project, a number of clinical ethics issues receive emphasis. (1) One cluster concerns the ethical concerns presented within the relationship between the providers (doctor, nurse, etc.) and patient (and family), as distinct from those associated with being a clinical ethics consultant invited into a situation to assist. (2) Distinct from these are ethical issues intrinsic to the ways in which clinical encounters are variously written about (from chart notes to published articles). (3) (...) Finally, there is a set of issues connected with the major characteristics of clinical encounters, in view of which it is imperative to be specifically attentive to the fine details and complex interactions among patient, doctor, family, and others, within a specific social context. Keeping these matters in mind helps to clarify the differences between consulting (talking and listening) and writing about consultations, as well as among the various kinds of writing about clinical encounters.

In what sense does time exist? Is it an objective feature of the external world? Or is its real nature dependent on the way man experiences it? Has modern science brought us closer to the answer to St. Augustine's exasperated outcry, 'What, then, is time?' ? Ever since Aristotle, thinkers have been struggling with this most confounding and elusive of philosophical questions. How long does the present moment last? Can we make statements about the future that are clearly true or (...) clearly false? And if so, must we be fatalists? This volume presents twenty-three discussions of the problem of time. A section on classical and modern attempts at definition is followed by four groups of essays drawn largely from contemporary philosophy, each preface with an introduction by the editor. First, in a chapter entitled 'The Static versus the Dynamic Temporal', four philosophers advance solutions to McTaggart's famous proof of time's unreality. In the next two sections, the discussion turns to the meaning of the 'open future' and to the much-debated nature of 'human time'. Finally, modern science and philosophy tackle Zeno's celebrated paradoxes. The essays by Adolf Grnbaum, Nicholas Rescher, and William Barrett are published for the first time in this volume.
