The unified treatment of the Dirac monopole, the Schwinger monopole, and the Aharonov-Bohm problem by Barut and Wilson is revisited via a path integral approach. The Kustaanheimo-Stiefel transformation of space and time is utilized to calculate the path integral for a charged particle in the singular vector potential. In the process of dimensional reduction, a topological charge quantization rule is derived, which contains Dirac's quantization condition as a special case. “Everything that is made beautiful and fair and lovely is (...) made for the eye of one who sees.” Jelaluddin Rumi,Mathnawi [I, 2383].

Widely adopted as a textbook, Issues and Alternatives in Educational Philosophy has been a classic in its field for more than a quarter of a century. As a survey of philosophic issues relevent to the educational profession, it highlights the relationship between philosophic starting points and educational outcomes - between theory and practice. -- from back cover.

Talk of group minds has arisen in a number of distinct traditions, such as in sociological thinking about the “madness of crowds” in the 19th-century, and more recently in making sense of the collective intelligence of social insects, such as bees and ants. Here we provide an analytic framework for understanding a range of contemporary appeals to group minds and cognate notions, such as collective agency, shared intentionality, socially distributed cognition, transactive memory systems, and group-level cognitive adaptations.

The book situates the works and reception of the French scholar Pierre de la Ramée (Petrus Ramus) in a variety of European cultural and educational contexts, from Britain and France to Eastern Europe, from Germany to the Iberian peninsula, and from Scandinavia to the Netherlands. Pierre de la Ramée or Petrus Ramus (1515-1572) has long been a controversial figure in educational reform and innovation, from the moment of his first public academic statements in the 1530s, to his reception among scholars (...) in the twentieth and twenty-first centuries. What is beyond dispute, however, is the vast reach of his influence throughout Europe. Ramus's ideas were disseminated through copious editions and translations of his own textbooks, and in wave after wave of adaptations and re-imaginings of his ideas that swept across the continent. This volume embarks on a European tour of Ramism, using a wide range of previously unpublished or untranslated archival evidence from throughout the continent to examine the dissemination of Ramus's works and his intellectual influence in geographic and in disciplinary terms. The ten chapters explore the spread of Ramism from his home country of France to Protestant strongholds in Germany, Holland, and Britain, and in the Catholic context of the Iberian peninsula. The book also examines Ramism in the less familiar territories (to most Anglophone readers) of Scandinavia and Hungary, and considers the preceding and contemporary Dutch and German educational reform movements from which Ramus borrowed to forge his own distinctive intellectual method.

Throughout its matrix of atoms, myoglobin has a network of cavities that are inhabited for short lengths of time by ligands released by photolysis from the myoglobin heme. The purpose or effect of this cavity network is not clear. A recently published kinetic scheme that fits data from many native and mutant myoglobin oxygen photolysis experiments can be modified easily into a kinetic scheme that includes kinetic proofreading. Proofreading would provide protection against contaminants and, specifically, might help protect the cell (...) from carbon monoxide poisoning. Here we present a two‐part model: (1) myoglobin represented by a kinetic description, which includes proofreading reactions associated with the cavities, and (2) a reaction–diffusion description of a myocyte model in which the part 1 myoglobin acts as a mobile buffer in simultaneous carbon monoxide and oxygen gradients. The non‐equilibrium nature of part 2 should promote the proofreading function of part 1. A simulation using the model demonstrates that the cavity system can in principle proofread, reducing mitochondrial enzyme contamination. BioEssays 26:422–433, 2004. © 2004 Wiley Periodicals, Inc.

In lieu of an abstract, here is a brief excerpt of the content:The Case of the Disappearing EnigmaDeborah Knight and George McKnightAsked to give examples of detection narratives, one might first mention paradigms of the detective genre from either the classical or hard-boiled traditions. But the study of detection need not be restricted to the generic as familiarly construed. 1 Our interest in detection is transgeneric, which is why we speak in terms of “detection narratives” rather than the (...) detective genre. We are as interested in detection narratives that exploit the generic tendencies of suspense or comedy as we are in nongeneric narratives that feature an investigation of some mystery or crime. While what we have to say about detection, interpretation, and narrative explanation is generally applicable to both literary and non-literary detection narratives, our five main examples are all unapologetically taken from cinema. We have selected these five just because they are unlikely to strike anyone as an intuitively obvious group of films. They are The Thin Man (W. S. Van Dyke, 1934), a mystery/comedy; The Maltese Falcon (John Huston, 1941), standardly cited as the earliest film noir and a paradigm of the cinematic hard-boiled detective genre; All The President’s Men (Alan J. Pakula, 1976), a political thriller based on Bernstein and Woodward’s nonfictional investigation of the Watergate break-in; Nicholas Roeg’s 1980 Bad Timing, a nongeneric film about sensual obsession; and Woody Allen’s 1993 comedy of manners, Manhattan Murder Mystery.Whether focusing on the investigation of a crime, the unraveling of a puzzle, or the solution of a mystery, detection narratives exhibit what Frank Kermode calls “a specialized ‘hermeneutic’ organization.” 2 As such, they call for a particular sort of investigation: namely, a hermeneutical one. Often we think about hermeneutical investigations as [End Page 123] interpretations and assume that the proper object of such interpretations is a text. Thinking primarily about literary texts, David Novitz argues that the function of such explanations is to “solve certain puzzles, answer certain questions, dispel confusions, or eliminate doubts about... the theme of a work or its plot, [or] about the actions, motives, or machinations of fictional characters....” 3Of course, interpretation is not restricted to literary texts, nor to answering specific questions about such matters as theme or plot or character motivation, nor does Novitz suggest it is. But when the object of interpretation is a text—literary, cinematic, legal, or other—it is arguable that interpretation is not restricted to those localized aspects of the text which we take to be puzzling. Novitz’s position is that interpretation only occurs when one confronts a specific puzzle or problem. What we understand directly is not, on this account, interpreted; interpretation is required only where we do not understand. The consideration of detection narratives suggests that understanding and interpretation are more closely related than Novitz seems to allow.In our attempts to make sense of the course of action of any detection narrative, there is always the question whether we have understood a given situation, event, action or statement correctly. It is always a question whether we have correctly distinguished between clues and red herrings. Detection narratives operate on the basis of a continual questioning—both for the detective and for the reader or viewer—as to whether we do, in fact, understand what is happening.This questioning attitude is keyed to the uncertainty as to whether we have correctly recognized what information is salient, which characters’ testimony is trustworthy. At various moments in any detection narrative, the detective (or reader/viewer) will have reason to question the reliability of their own assessment of what is going on. There is the risk of being mistaken, but also the risk of being deceived. So the appropriate attitude to detection narratives is an interpretive one, an attitude that asks questions about what is presented.Of course, particular questions cannot even be sensibly asked in the absence of a larger interpretive framework which gives the particular question its point. Not only the detective, but the reader or viewer, is well advised to contextualize any particular event or action as a (potential) part of what we call, adapting a notion of David Carr’s, an action of large...

In works of literary fiction, it is a part of the fiction that the words of the text are being recounted by some work-internal 'voice': the literary narrator. One can ask similarly whether the story in movies is told in sights and sounds by a work-internal subjectivity that orchestrates them: a cinematic narrator. George M. Wilson argues that movies do involve a fictional recounting (an audio-visual narration ) in terms of the movie's sound and image track. Viewers are (...) usually prompted to imagine seeing the items and events in the movie's fictional world and to imagine hearing the associated fictional sounds. However, it is much less clear that the cinematic narration must be imagined as the product of some kind of 'narrator' - of a work-internal agent of the narration. Wilson goes on to examine the further question whether viewers imagine seeing the fictional world face-to-face or whether they imagine seeing it through some kind of work-internal mediation . It is a key contention of this book that only the second of these alternatives allows one to give a coherent account of what we do and do not imagine about what we are seeing on the screen. Having provided a partial account of the foundations of film narration, the final chapters explore the ways in which certain complex strategies of cinematic narration are executed in three exemplary films: David Fincher's Fight Club , von Sternberg's The Scarlet Empress , and the Coen brothers' The Man Who Wasn't There.

If a person's head moves, she may or may not have moved her head, and, if she did move it, she may have actively performed the movement of her head or merely, by doing something else, caused a passive movement. And, if she performed the movement, she might have done so intentionally or not. This short array of contrasts (and others like them) has motivated questions about the nature, variety, and identity of action. Beyond the matter of her moving, when (...) the person moves her head, she may be indicating agreement or shaking an insect off her ear. Should we think of the consequences, conventional or causal, of physical behavior as constituents of an action distinct from but ‘generated by’ the movement? Or should we think that there is a single action describable in a host of ways? Also, actions, in even the most minimal sense, seem to be essentially ‘active’. But, how can we explain what this property amounts to and defend our wavering intuitions about which events fall in the category of the ‘active’ and which do not? (shrink)

This article argues, first, that the fundamental structure of the skeptical argument in Kripke's book on Wittgenstein has been seriously misunderstood by recent commentators. Although it focuses particularly on recent commentary by John McDowell, it emphasizes that the basic misunderstandings are widely shared by other commentators. In particular, it argues that, properly construed, Kripke offers a fully coherent reading of PI #201 and related passages. This is commonly denied, and given as a reason for rejecting Kripke's reading of Wittgenstein's text. (...) Second, it is pretty universally accepted that Kripke's Wittgenstein is a `non-factualist' about ascriptions of meaning. The article argues that, when Kripke's discussion is rightly understood and the content of `non-factualism' is clarified, there is an important sense in which the skeptical solution is not committed to non-factualism.

In a recent paper, Ebbs has given an elegant statement of a notable puzzle that has recurred in the literature since the original publication of Putnam’s “The Meaning of ‘Meaning’.” The puzzle can be formulated, for a certain characteristic case, along the following lines. There are very strong intuitions in support of a thesis that Putnam has explicitly endorsed, namely, the thesis: The extension of the word ‘gold’, as we use it now, is the same as the extension of ‘gold’, (...) as it was used in 1650 (before the rise of molecular chemistry). However, strong convictions about language use and truth conditions also incline us to the view that the extension of a term, as it is used at a time t, is determined by facts about the use of the term in the language at or before t, together with the facts about the various items to which the term prospectively applied. This paper looks at the various issues involved regarding these matters. (shrink)

The liver progenitor cell (LPC) has enormous potential for use in cell therapy to treat liver disease. Since liver regenerates readily from pre‐existing hepatocytes, a role for LPCs and, indeed, their existence have been questioned. Research during the last decade has established that LPCs are an important alternative source of cells for liver regeneration. Their utility for cell therapy lies in their ability to generate both hepatocytes and cholangiocytes. However, they are observed in liver diseases that often lead to cancer (...) and there is experimental evidence that implicates LPCs as the source of tumours. This article provides a brief history of the studies that established the functional importance of LPCs in liver disease. It focuses on mouse models that have led to the identification of factors that regulate LPC growth and differentiation and discusses LPCs derived from different sources. Recent promising results from both in vitro and vivo studies suggest that LPCs could be useful for cell therapy. In the context of liver disease, LPCs may indeed be the cell of the future and understandably “our favourite cell”. BioEssays 27:1192–1202, 2005. © 2005 Wiley Periodicals, Inc. (shrink)

It is widely held in theories of narrative that all works of literary narrative fiction include a narrator who fictionally tells the story. However, it is also granted that the personal qualities of a narrator may be more or less radically effaced. Recently, philosophers and film theorists have debated whether movies similarly involve implicit audio-visual narrators. Those who answer affirmatively allow that these cinematic narrators will be radically effaced. Their opponents deny that audio-visual narrators figure in the ontology of movies (...) at all, and many have argued that the ‘effaced’ literary narrator is an illusion as well. In this paper, I attempt to sort out the central issues that arise in these debates, defending the existence of effaced narrators in both literature and film. (shrink)
