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].

In this paper, we discuss our approach to developing engaging course content linked to distinct learning outcomes on the topic of academic authorship. Academic authorship is a critical element of research culture and responsible conduct of research (RCR) courses. Drawing on instructional design methods, our online course aims to stimulate critical thinking about ethical authorship practices and to help students develop skills for resolving authorship-related conflicts. The course is scaffolded to facilitate engagement by tying video and podcast-style media, a choice-based (...) interactive simulation, and traditional case study activities, to specific learning objectives. We describe how each instructional technique enhances student engagement and learning for the paired objective, and the benefits of the holistic course design. Finally, we illustrate how RCR instructors can incorporate our materials in full or in part into their own course curricula and encourage others to use our course development approach when designing their own courses.

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.

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.

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)

This thesis is a constructive work in the tradition of morality. The thesis divides into three parts. Part One argues that morality is best considered as a tradition (in MacIntyre’s sense) in ethical thinking which begins with the Stoics, develops in Christian thought and reaches its apotheosis in Kant. This tradition structures ethical thinking around three basic concepts: cosmopolitanism, or universal applicability to human beings as such, the dignity of human beings and reciprocity. It is this tradition in ethical thinking (...) which Nietzsche sets out to destroy. Part One then critiques conceptions of morality which take it that universal and exceptionless rules form the core of morality: it criticises both the possibility of putting forward an adequate set of such rules and the proposed relationship between morality and human life that is implicit in these accounts. Part Two begins with Nietzsche’s challenge: that morality is a system of values rooted in nihilistic resentment at the vitality of other, stronger modes of living. It argues that this challenge must be taken seriously, and that the best way to do this is to make it clear that morality has as its fundamental basis a responsiveness to the value of human life; hence it is Nietzsche’s ethics that should be called nihilistic. The rest of Part Two examines the possibility of answering Nietzsche’s challenge by demonstrating a necessary connection between human selfhood and the acknowledgement of the dignity of human beings. Here I argue that neither Christine Korsgaard’s neo-Kantian arguments nor Charles Taylor’s phenomenologically based approach can provide a convincing reason for thinking that there is such a necessary connection. Part Three turns towards pragmatism, and in so doing gives up on the attempt to show that morality is somehow necessary for all human beings. Nietzsche’s challenge is answered more subtly: an empirically backed theory of human selfhood explains the point of morality in terms of our basic need for recognition. I complete the reconstruction of morality by reinterpreting the dignity of human beings in a naturalistic way and adopting a conception of moral rules that is informed by Jürgen Habermas’ discourse ethics.

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)

This article starts out by delineating an interpretation of Kripke on Wittgenstein, an interpretation that seems to stand the best chance of fitting at least the basic concerns and insights expressed in the Investigations. In doing so, this article sketches a conception of meaning and truth conditions against which Wittgenstein's remarks are plausibly directed, and it explains how Kripke's reconstruction of Wittgenstein can be read as incorporating a broad attack on that conception. The interpretation with which the article opens offers (...) what the article calls ‘the dramatic reading of the Skeptical Argument.’. (shrink)

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.

Analyzes cinematic conventions of transparency, and offers an interpretation of Fight Club.

A sentence of the formEither Jones or Smith entered the room, and he saw the Maltese Falcon,has some notable properties due largely to the sprightly behavior of the pronoun in its second conjunct. For instance, that pronoun can not be a pronoun of laziness for the disjunctive noun phrase, ‘Jones or Smith,’ since patently does not express the thought that Either Jones or Smith entered the room, and either Jones or Smith saw the Maltese Falcon., but not, would be true (...) if Jones entered the room but didn't see the Maltese Falcon, and Smith saw the Maltese Falcon but never entered the room.

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)
