Meta-programs, which treat other computer programs as data, include compilers, editors, simulators, debuggers, and program transformers. Because of the wide ranging applications, meta-programming has become a subject of considerable practical and theoretical interest. This book provides the first comprehensive view of topics in the theory and application of meta-programming, covering problems of representation and of soundness and correctness of interpreters, analysis and evaluation of meta-logic programs, and applications to sophisticated knowledge-based systems.Harvey Abramson is Reader in Computer Science at (...) the University of Bristol, England; M. H. Rogers is Professor of Computer Science, also at the University of Bristol. Meta-Programming in Logic Programming is in the series Logic Programming Research Reports and Notes, edited by Ehud Shapiro. (shrink)

In 1991, Jones developed an issue-contingent model of ethical decision making in which moral intensity is posited to affect the four stages of Rest's 1986 model. Jones claimed that moral intensity, which is "the extent of issue-related moral imperative in a situation", consists of six characteristics: magnitude of consequences, social consensus, probability of effect, temporal immediacy, proximity, and concentration of effect. This article reports the findings of two studies that analyzed the factor structure of moral intensity, operationalized by a 12-item (...) Perceived Moral Intensity Scale adapted from the work of Sing-hapakdi et al. [1996, Journal of Business Research, 36, 245-255] and Frey [2000, Journal of Business Ethics, 26, 181-195]. The two items that were purported to measure CE were dropped due to their inability to effectively tap into the characteristic proposed by Jones. Factor analyses of the remaining 10 items supported a 3-factor structure, with the MC, PE, and TI items loading on the first factor, the PX items loading on the second factor, and the SC items loading on the third factor. These factors were labeled: Probable Magnitude of Consequences, Proximity, and Social Consensus. The authors conclude that moral intensity consists of three characteristics, rather than the six posited by Jones. (shrink)

The factor structure of the Multidimensional Ethics Scale (MES; Reidenbach and Robin: 1988, Journal of Business Ethics 7, 871–879; 1990, Journal of Business Ethics 9, 639–653) was examined for the 8-item short form (N = 328) and the original 30-item pool (N = 260). The objectives of the study were: to verify the dimensionality of the MES; to increase the amount of true cross-scenario variance through the use of 18 scenarios varying in moral intensity (Jones: 1991, Academy of Management Review (...) 16, 366–395); and, to examine the items for measurement precision using item-response theory (IRT) methods. Results of confirmatory and exploratory factor analysis failed to conclusively support the hypothesized 3- (short form) or 5-factor (long form) structure; both instruments were instead dominated by a general factor. Item response theory analyses using Samejima’s (1969, Psychometrika Monograph Supplement 34, (4, Pt. 2)) graded response model revealed that many items in the 30-item pool performed very well, and suggested that a different collection of items be used to form a short-form version of the MES. Our proposed 10-item instrument includes more discriminating items than the 8-item version, and has the added advantage of including two items from each of the five ethical philosophies represented in the original 30-item pool.

Should advance directives (ADs) such as living wills be employed to direct the care of the severely demented? In considering this question, I focus primarily on the claims of Rebecca Dresser who objects in principle to the use of ADs in this context. Dresser has persuasively argued that ADs are both theoretically incoherent and ethically dangerous. She proceeds to advocate a Best Interest Standard as the best way for deciding when and how the demented ought to be treated. I put (...) forth a compromise position: both ADs and the Best Interest Standard have roles to play in guiding the care of the severely demented. (shrink)

PrécisThe administration of Pre-Mortem Interventions (PMIs) to preserve the opportunity to donate, to assess the eligibility to donate, or to optimize the outcomes of donation and transplantation are controversial as they offer no direct medical benefit and include at least the possibility of harm to the still-living patient. In this article, we describe the legal analysis surrounding consent to PMIs, drawing on existing legal commentary and identifying key legal problems. We provide an overview of the approaches in several jurisdictions that (...) have chosen to explicitly address PMIs within codified law. We then provide, as an example, a detailed exploration of how PMIs are likely to be addressed in one jurisdiction where general medical consent law applies because there is no specific legislation addressing PMIs — the province of Ontario in Canada.

Teaching economics has been shown to encourage students to defect in a prisoner's dilemma game. However, can ethics training reverse that effect and promote cooperation? We conducted an experiment to answer this question. We found that students who had the ethics module had higher rates of cooperation than students without the ethics module, even after controlling for communication and other factors expected to affect cooperation. We conclude that the teaching of ethics can mitigate the possible adverse incentives of the prisoner's (...) dilemma, and, by implication, the adverse effects of economics and business training.

A fascinating account of exemplarity in the context of deconstruction.

Let ℜ be an o-minimal expansion of (ℝ, <+) and (φk)k∈ℕ be a sequence of positive real numbers such that limk→+∞f(φk)/φk+1=0 for every f:ℝ→ ℝ definable in ℜ. (Such sequences always exist under some reasonable extra assumptions on ℜ, in particular, if ℜ is exponentially bounded or if the language is countable.) Then (ℜ, (S)) is d-minimal, where S ranges over all subsets of cartesian powers of the range of φ.

Following an earlier paper in the journal in which Evans argued that it was commercial exploitation, not mere payment, that was morally objectionable about certain sorts of organ donation, this paper looks at the moral issues when commercial exploitation is eliminated from systems of paid organ donation. It argues that there are no conclusive moral arguments against such schemes for non-exploitative paid kidney donation.

It is proposed in this paper that enzymes, by virtue of a number of correctly positioned sites of interaction with substrates, can force the compression of hydrogen bonds, increasing the probability of proton transfer by quantum mechanical tunneling. By such a catalytic mechanism a rate enhancement of many orders of magnitude may be obtained with a very low energy input requirement. The mechanism would, however, require a highly structured catalyst.Pertinent aspects of hydrogen bond theory and of tunneling theory are briefly (...) reviewed. (shrink)

This textbook carefully develops the main ideas and techniques of statistical and thermal physics and is intended for upper-level undergraduate courses. The authors each have more than thirty years' experience in teaching, curriculum development, and research in statistical and computational physics. Statistical and Thermal Physics begins with a qualitative discussion of the relation between the macroscopic and microscopic worlds and incorporates computer simulations throughout the book to provide concrete examples of important conceptual ideas. Unlike many contemporary texts on thermal physics, (...) this book presents thermodynamic reasoning as an independent way of thinking about macroscopic systems. Probability concepts and techniques are introduced, including topics that are useful for understanding how probability and statistics are used. Magnetism and the Ising model are considered in greater depth than in most undergraduate texts, and ideal quantum gases are treated within a uniform framework. Advanced chapters on fluids and critical phenomena are appropriate for motivated undergraduates and beginning graduate students. Integrates Monte Carlo and molecular dynamics simulations as well as other numerical techniques throughout the text Provides self-contained introductions to thermodynamics and statistical mechanics Discusses probability concepts and methods in detail Contains ideas and methods from contemporary research Includes advanced chapters that provide a natural bridge to graduate study Features more than 400 problems Programs are open source and available in an executable cross-platform format Solutions manual.

ABSTRACTThe financial crisis of 2008 was unforeseen partly because the academic theories that underpin policy making do not sufficiently account for uncertainty and complexity or learned and evolved human capabilities for managing them. Mainstream theories of decision making tend to be strongly normative and based on wishfully unrealistic “idealized” modeling. In order to develop theories of actual decision making under uncertainty, we need new methodologies that account for how human actors often manage uncertain situations “well enough.” Some possibly helpful methodologies, (...) drawing on digital science, focus on the role of emotions in determining people's choices; others examine how people construct narratives that enable them to act; still others combine qualitative with quantitative data.

This book examines central themes in the thought of Rabbi Hasdai Crescas (c. 1340-1410/11), the great Catalan Jewish philosopher who contributed to the revolution of modern science and profoundly influenced Spinoza. Part I treats of Crescas' radical critique of the Aristotelian concepts of space, time, and the vacuum, and analyzes his vision of an infinite universe; it discusses his criticisms of Maimonides' proofs of God, and expounds his own proof; and it concludes with a discussion of his concept of God (...) as infinite Love. Part II contains three essays on Crescas' strictly deterministic theory of human choice. (shrink)

Is genuinely just behavior possible for Hobbesian agents? More perspicuously, does Hobbes allow that at least some individuals conceive of justice as not simply a means to self-preservation, but furthermore, as a worthwhile end in its own right? In a recent issue of Hobbes Studies I answered both of these questions in the affirmative.1 Therein, however, for reasons of space I neglected to explore and defend adequately Hobbes's conception of the "Just Man" as someone for whom genuinely just behavior is, (...) in the Jamesian sense, a "live option." I intend to correct this scholarly deficit forthwith by proffering what I consider to be a thorough defense thereof. Those who advocate the Standard Reading of Hobbes as an egoist will, of course, α priori dismiss such claims as "astonishing" to say the least.2 Nonetheless, if my exegesis and defense is successful then SR will have to undergo a transformation; succinctly, proponents of SR will be forced to acknowledge the Just Man's presence and to weaken their presuppositions and conclusions accordingly . I begin by cataloging and critically commenting upon the numerous references Hobbes makes to the "Just Man" throughout the major works that constitute his moral and political corpus: The Elements of Law , De Cive and both the English and Latin versions of Leviathan .3 I then turn in the next section to a defense of the possibility of genuinely just behavior on the part of Hobbesian individuals by responding to four powerful objections proffered by the proponents of SR.

I make three points. First, processors and depletable resources should not be regarded as alternative means of processing information: they are both necessary. Second, comparing a processor account with a rational allocation mechanism to a depletable-resources account without one is not a fair comparison. Third, depletable resources can act as signals as well as fuels.
