The authors claim that disciplinary epistemologies—disciplinary habits of mind and ways of thinking—offer productive lenses for observing teaching practices. Furthermore, they argue that educational developers who draw from multiple epistemologies in combination provide rich evidence with regard to teaching and learning and can speak to academic colleagues from an array of disciplines. Clarity is provided for career paths in educational development for colleagues from academic disciplines who are contemplating part‐ or full‐time work in a teaching center. The authors hope that (...) this opening collection develops into a toolkit and area of inquiry about disciplinary approaches to the practice of educational development. (shrink)

In the past decade, the notion of a neural correlate of consciousness has become a focal point for scientific research on consciousness. A growing number of investigators believe that the first step toward a science of consciousness is to discover the neural correlates of consciousness. Indeed, Francis Crick has gone so far as to proclaim that ‘we need to discover the neural correlates of consciousness. For this task the primate visual system seems especially attractive. No longer need one spend time (...) attempting to endure the tedium of philosophers perpetually disagreeing with each other. Consciousness is now largely a scientific problem’. Yet the question of what it means to be a neural correlate of consciousness is actually far from straightforward, for it involves fundamental empirical, methodological, and philosophical issues about the nature of consciousness and its relationship to the brain. Even if one assumes, as we do, that states of consciousness causally depend on states of the brain, one can nevertheless wonder in what sense there is, or could be, such a thing as a neural correlate of consciousness.

Published in 1987: The following essays form, as their title-page shows, only the first half of a collection which the writer hopes to complete in the course of a few months. Even when completed the whole work is designed to be merely preparatory to another on the interpretation of the Platonic Philosophy, and the materials brought together in the following pages, as well as those which, it is trusted, will form their continuation, were originally intended to appear in the Introduction (...) to that projected work.

In this study, complex dynamics of Briggs–Rauscher reaction system is investigated analytically and numerically. First, the Briggs–Rauscher reaction system is reduced into a new nonlinear parametric oscillator. The Melnikov method is used to derive the condition of the appearance of horseshoe chaos in the cases ω = Ω and ω ≠ Ω. The performed numerical simulations confirm the obtained analytical predictions. Second, the prediction of coexisting attractors is investigated by solving numerically the new nonlinear parametric ordinary differential equation via the (...) fourth-order Runge–Kutta algorithm. As results, it is found that the new nonlinear chemical system displays various coexisting behaviors of symmetric and asymmetric attractors. In addition, the system presents a rich variety of bifurcations phenomena such as symmetry breaking, symmetry restoring, period doubling, reverse period doubling, period-m bubbles, reverse period-m bubbles, intermittency, and antimonotonicity. On the contrary, emerging chaotic band attractors and period-1, period-3, period-9, and period-m bubbles routes to chaos occur in this system. (shrink)

A provocative Target Article in this issue of AJOB proposes a new approach to decision-making for babies born in the “gray-zone” at the margins of viability. Titled “Postponed Withholding: balanced...

One of the ways in which a poet may show his quality is by discrimination and originality in his choice of adjectives. Poetry likes to adorn the bare noun; a noun such as ‘the sky’ calls out for an attribute. But in practice the poet has to take care to avoid the cliche. He can seldom write ‘the blue sky’; even ‘the azure sky’ has become trite. He has to search for the epithet which will be both apt and original.

Abstract This chapter addresses the meta-ethical and psychological implications of Murdoch’s epistemic internalism—her claim that moral responsiveness is a condition of reliable and accurate moral evaluations. Part 1 examines Murdoch’s view that moral judgments feature a quasi-experiential phenomenology analogous to that of certain perceptual ones. Focussing on the phenomenology of our perception-based judgments of certain aspectual properties (e.g., pictorial and musical ones) it argues that such judgments support both Murdoch’s analogy and the internalism she takes it to imply. In Part (...) 2 this chapter considers Murdoch’s internalism as a psychological thesis, assessing it in view of several empirical studies of psychopathic subjects. It argues that the psychopath’s distinctive complex of cognitive and motivational deficits supports Murdoch’s conviction that moral judgment and moral motivation are interdependent. Just as Murdoch believed, many of our ordinary, non-pathological moral beliefs seem to be the natural progeny of our responsiveness to other persons, and so inherit the intrinsic power that others have to move us.

A significant two-fold development in recent classical scholarship has been a revival of interest in, and respect for, post-Aristotelian Greek philosophy and Cicero's contribution to our knowledge of it. Of Cicero's major works in this field the Tusculan disputations is perhaps the most approachable.

High-frequency oscillations emerged as a neural code for both positive affect and fluent attentional processing from evolutionary simulations with artificial neural networks. Visual 50 Hz flicker, which entrains neural oscillations in the gamma band, has been shown to foster attentional switching, but can it also elicit positive affect? A three-faces display was preceded by a 50, 25, or 0 Hz flicker on the position of the odd-one-out . Participants decided on the gender or on the subjective valence of this neutral (...) target in an approach-avoidance task, which served as an implicit affective measure. Only the detection of 25 Hz flicker, but not of 50 Hz flicker, was above chance . Faces primed by invisible 50 Hz flicker were explicitly evaluated more positively than with 25 Hz or 0 Hz. This gamma flicker also facilitated approach reactions, and inhibited avoidance reactions relative to 25 Hz and 0 Hz flicker in Blocks 1 and 2. Attentional switching was, moreover, enhanced by the 50 Hz flicker. According to the Affect–Gamma hypothesis, also in biological neural networks, high-frequency gamma oscillations may code for positive affect. (shrink)

Correction . Online publication date: 2‐Feb‐2006. We inadvertently printed three erroneous internal cross references in S. H. Rigby's review of Miguel Cabrera's Postsocial History: An Introduction in theFebruary 2006 issue of : On p. 114, "p. 458" should read "p. 112." On p. 120, the two references to "p. 460" should both read "p. 114." Professor's Rigby's review was rescheduled from an earlier issue and unfortunately we did not notice that these references needed to be updated.

The numerous historical episodes of free banking have invariably ended in the establishment of central banking. Was the failure of free banking due to ?theory,? ?seignorage??the attempt by governments to use central banks for revenue purposes?or to ?crises?? Would a free banking system be stable, free of crises? This is the crux of the theoretical and historical debate.
