In this paper I shall attempt to analyze some comparative aspects of modern societies which bear on the problem of convergence of modern, especially industrial, societies and the closely related analytical problems of the relations between culture and social structure.

Heterodoxy, sects and sectarianism seemingly belong to the sphere of religions; they obviously refer to doctrinal organizational and behavioral aspects of dissension within the frameworks of religions. It would, however, be wrong to think that their importance is confined only within such frameworks—broad and important as they are. The importance of heterodoxy and sectarianism is indeed much wider. It is much wider not only because the term sect has been often used—as Roger Caillois has demonstrated in his brilliant essay on (...) “L'Esprit des Sectes”—to refer to a much broader range of phenomena in the overall political and social order. The very possibility of using this term beyond its strictly religious connotation indicates that the developments of sectarianism, rooted as it is in the sphere of religion, are, potentially at least, of much broader implications.This was, of course, most clearly seen and elaborated by Max Weber who, in his classical essays on the comparative sociology of religions, was among the first to stress the place of dissent and heterodoxy, not only from the point of view of the doctrinal or organizational development of various religions, but from the broader point of view of the broader civilizational dynamics, of the innovative capacity of different civilizations.

Argument invention is a method that can be used to help an arguer find arguments that could be used to prove a claim he needs to defend. The aim of this paper is to show how argumentation systems recently developed in artificial intelligence can be applied to the task of argument invention. One such system called Carneades is featured. Carneades can be used to analyze arguments, evaluate arguments, to make an argument diagram, and to construct arguments from a database. Using (...) some simple examples, the paper explains how Carneades works as a system of argument invention. (shrink)

In their article in the September-October 2010 issue of IRB: Ethics & Human Research, Chris Kaposy and Françoise Baylis argue that the contraception policy of the University of Nebraska Medical Center’s institutional review board fails to meet an ethically ideal standard in establishing the criteria investigators should follow when including women of childbearing potential in clinical research. In this response, we argue that the UNMC IRB’s policy is evidence-based and pragmatically oriented and that it therefore better safeguards women’s autonomy than (...) an ideal policy could. We also offer some of our experiences with the policy since it was implemented six years ago. (shrink)

How do educators better reach their students, better capture their attention and imagination without sacrificing scholarship? Teachable Moments: Essays on Experiential Education examines the pedagogy of Prescott College, a school that has embraced experiential education and been finding success with it for over thirty years. These essays—from scholars in fields as wide ranging as religious studies, environmental science, psychology, dance, literature, adventure education, and peace studies—examine the challenges and, ultimately, the rewards of student-centered education.

In this paper I will present conceptions of state reduction and particle and/or system localization which render these subjects fully compatible with the general requirements of a relativistic, i.e. Lorentz invariant, quantum theory. The approach consists of a systematic generalization of the concepts of initial data assignment at definite times, initiation and completion of measurements at definite times, and dynamical evolution as time dependence, to the concepts of initial data assignment on arbitrary space-like hyperplanes, initiation and completion of measurements on (...) arbitrary space-like hyperplanes, and dynamical evolution as space-like hyperplane dependence, respectively. I also briefly discuss the superluminal propagation which emerges from the localization study and the manner in which causal anomalies are nevertheless avoided. (shrink)

The Reeh-Schlieder theorem asserts the vacuum and certain other states to be spacelike superentangled relative to local fields. This motivates an inquiry into the physical status of various concepts of localization. It is argued that a covariant generalization of Newton-Wigner localization is a physically illuminating concept. When analyzed in terms of nonlocally covariant quantum fields, creating and annihilating quanta in Newton-Wigner localized states, the vacuum is seen to not possess the spacelike superentanglement that the Reeh-Schlieder theorem displays relative to local (...) fields, and to be locally empty as well as globally empty. Newton-Wigner localization is then shown to be physically interpretable in terms of a covariant generalization of the center of energy, the two localizations being identical if the system has no internal angular momentum. Finally, some of the counterintuitive features of Newton-Wigner localization are shown to have close analogues in classical special relativity. (shrink)

Through the explicit introduction of hyperplane dependence as a form of relativistic dynamical evolution, we construct a manifestly covariant description of a single positive energy particle interacting with any one of a large class of “moving” external potentials. In1+1 dimensions, the simplified mathematics allows us to display a number of general properties of solutions to the equations of motion for evolution on hyperplanes.
