This book presents a mathematical programming approach to the analysis of production frontiers and efficiency measurement. The authors construct a variety of production frontiers, and by measuring distances to them are able to develop a model of efficient producer behaviour and a taxonomy of possible types of departure from efficiency in various environments. Linear programming is used as an analytical and computational technique in order to accomplish this. The approach developed is then applied to modelling producer behaviour. By focusing on (...) the empirical relevance of production frontiers and distances to them, and applying linear programming techniques to artificial data to illustrate the type of information they can generate, this book provides a unique study in applied production analysis. It will be of interest to scholars and students of economics and operations research, and analysts in business and government. (shrink)
The question 'Why should I obey the law?' introduces a contemporary puzzle that is as old as philosophy itself. The puzzle is especially troublesome if we think of cases in which breaking the law is not otherwise wrongful, and in which the chances of getting caught are negligible. Philosophers from Socrates to H.L.A. Hart have struggled to give reasoned support to the idea that we do have a general moral duty to obey the law but, more recently, the greater number (...) of learned voices has expressed doubt that there is any such duty, at least as traditionally conceived.

The coordinate-free methods of the preceding paper are illustrated in three problems. First, the electrodynamics of a homogeneous, isotropic, and gyrotropic medium is investigated; it is shown that such a medium can exhibit optical activity, and the propagation of a plane electromagnetic wave in such a medium is discussed. Then, the electrodynamics of a homogeneous system made anisotropic by a uniform external magnetic field is considered; a description of Faraday rotation is provided, the ionosphere being used in an example. Finally, (...) the reflection and refraction of a plane electromagnetic wave at the interface of two media are described by coordinate-free operators. (shrink)
Paul Churchland proposed a conceptual framework for translating reflectance profiles into a space he takes to be the color qualia space. It allows him to determine color metamers of spectral surface reflectances without reference to the characteristics of visual systems, claiming that the reflectance classes that it specifies correspond to visually determined metamers. We advance several objections to his method, show that a significant number of reflectance profiles are not placed into the space in agreement with the qualia solid, and (...) produce two sets of counterexamples to his claim for metamers.

In many systems, the tensors used to describe physical properties must acquire their structure from one vector. Knowledge of that fact alone leads to an interesting line of analysis for such systems. The analysis begins with a discussion of the types of dyadics that can be constructed from one vector. Attention is focused on certain exemplary dyadic operators, which, because of their geometrical properties, would appear particularly basic; the algebra of these dyadics is developed in detail. The algebra is then (...) used in a derivation of the expansion of general functions of these dyadics. Several applications of the general expansion are presented: the inverse of a general dyadic operator (when it exists), a general rotation operator that includes strains and reflections, the determinant of a general dyadic operator, and operators, including some new ones, used in constructing Lorentz boosts. Finally, a coordinate-free representation of the Levi-Civita tensor is provided. (shrink)
Although counterproductive work behaviors can be extremely damaging to organizations and society as a whole, we do not yet fully understand the link between employees’ organizational attachment and their intention to engage in such behaviors. Based on social identity theory, we predicted a negative relationship between organizational identification and counterproductive work behaviors. We also predicted that this relationship would be moderated by ambivalent identification. We explored counterproductive work behaviors toward the organization and other individuals. Study 1, a survey of 198 (...) employees, revealed that employees who identified strongly with their organization reported lower levels of CWB-O, but as predicted, only when ambivalent identification was low. Study 2 involved a manipulation in the form of a scenario presented to 228 U.S. employees, generally replicated the findings of Study 1: the link between organizational identification and CWB-O was stronger for participants in the low ambivalence condition than for those in the high ambivalence condition. The interaction effect of ambivalent and organizational identification on CWB-I was only marginally significant in the second study. These findings provide new evidence for the positive influence of organizational identification under conditions of low ambivalence on counterproductive behaviors toward an organization. (shrink)
Previous research has shown that female leaders lead slightly more effective than male leaders. However, women are still underrepresented in higher management. In this study, we seek to contribute to a deeper understanding of this paradox by proposing and testing an innovative model that integrates different research streams on gender and leadership. Specifically, we propose power motivation and transformational leadership as two central yet opposing dynamics that underlie the relation between gender and leadership role occupancy. We tested this model in (...) a sample of 256 employees. Results provided support for the proposed relations. These findings contribute to a more detailed and comprehensive understanding for central dynamics that link gender and leadership role occupancy. Moreover, they provide important insights for interventions that are targeted at reducing the gender gap in leadership. We discuss the theoretical and practical implications of these findings.

Although the proportion of women in leadership positions has grown over the past decades, women are still underrepresented in leadership roles, which poses an ethical challenge to society at large but business in particular. Accordingly, a growing body of research has attempted to unravel the reasons for this inequality. Besides theoretical progress, a central goal of these studies is to inform measures targeted at increasing the share of women in leadership positions. Striving to contribute to these efforts and drawing on (...) several theoretical approaches, the present study provides a contemporary examination of whether women and men differ in their levels of power motivation and whether potential gender differences in this motivation contribute to the unequal distribution of women and men in leadership positions. Results from four studies provide converging support for these assumptions. Specifically, we found that women consistently reported lower power motivation than men. This in turn mediated the link between gender and leadership role occupancy. These results were robust to several methodological variations including samples from different populations, diverse operationalizations of power motivation and leadership role occupancy, and study design. Implications for theory and practice, including ways to contribute to a more equal gender distribution in leadership positions, are discussed. (shrink)
Bill Cosby’s immorality has raised intriguing aesthetic and ethical issues. Do the crimes that he has been convicted of lessen the aesthetic value of his stand-up and, even if we can enjoy it, should we? This article first discusses the intimate relationship between the comedian and audience. The art form itself is structurally intimate, and at the same time the comedian claims to express an authentic self on stage. After drawing an analogy between the question of the moral character of (...) comedians and the aesthetic value of their stand-up and the debate over the ethical criticism of art, this article argues that it is reasonable to find a comedian’s performance less funny, because stand-up’s artistic success relies on this intimacy. It contrasts the comedy of Bill Cosby with that of Louis C.K. C.K.’s moral flaws are much more present in his comedy, and it is therefore more difficult to find him funny. Last, it is ethically permissible to enjoy their comedy, if no harm to others results, both because it does not corrupt the audience’s character and because amusement is valuable. (shrink)
The object of this essay is to discuss two problems and to present solutions to them, which do not quite agree with what is generally said of them. The first problem concerns the history of methods for reaching firm historical knowledge. In three methodological manuals for historians, written by J. G. Droysen, E. Bernheim, and C.-V. Langlois and C. Seignobos and first published in the late nineteenth century, the task of the historian was said to be how to obtain firm (...) knowledge about history. The question is how this message should be understood. The second problem concerns the differences between the three manuals. If their common goal is firm historical knowledge, are there any major differences of opinion? The answer given in this article is yes, and the ground is sought in their theories of truth. (shrink)
In this article, we hypothesize that leaders who display group-oriented values (i.e., values that focus on the welfare of the group rather than on the self-interest of the leader) will be evaluated more positively by their followers than leaders who do not display group-oriented values. Importantly, we expected these effects to be more pronounced for leaders who are ingroup members (i.e., stemming from the same social group as their followers) than for leaders who are outgroup members (i.e., leaders stemming from (...) a different social group than their followers). We tested our hypotheses in two studies. Results of a field study ( N = 95) showed the expected relationship between leaders’ group-oriented values and followers’ identification with their leaders. A scenario study ( N = 137) replicated the results and extended it to followers’ endorsement of their leaders. Overall, these findings suggest that displaying group-oriented values pays off more for ingroup than for outgroup leaders. (shrink)

La phénoménologie radicale de Michel Henry montre que la question de la réceptivité en tant que passivité est au cœur de toute élucidation phénoménologique dans la mesure où nous naissons dans la Vie absolue sans aucune initiative de notre part. Devant une telle situation, la réflexion discursive se montre dépourvue de ses moyens habituels, ce qui entraîne une double stratégie : accuser une telle phénoménologie radicale d'être une totalisation métaphysique ou lui reconnaître seulement une certaine valeur méthodologique, c'est-à-dire opératoire pour (...) la réduction. Notre contribution voudrait établir qu'il s'agit chaque fois, dans des discours similaires, d'une méconnaissance de la « violence » originaire que nous subissons de la part de la vie — violence qui est en même temps notre véritable Bonheur et Demeure. Michel Henry's radical phenomenology shows that receptivity is at the core of any phenomenological elucidation in so far as we are born in Absolute Life without any initiative on our part. Confronted to such a situation, discursive reflection appears to be deprived of its traditional means, which entails a twofold strategy : i.e. on the one hand, accusing such a radical phenomenology of being a metaphysical totalisation or, on the other hand, acknowledging it as a mere methodological value, i.e. an operative one towards reduction. Our contribution would thus try and set that every time, within similar discourses, what is at stake is a misconception of the primary « violence » we suffer from life – a violence which is at the same both our true Happiness and Home.

It is pointed out against the two critics (a) that an identity or partial identity of meanings and facts is logically impossible, (b) that the logical grammar of ?identify? and ?explain? is different from that of ?understand? and that hence understanding can never be an operation of identifying or explaining, and (c) that rational understanding does not involve a ?reproduction? of the subject matter in any controversial sense.
In this volume C.A. (Chet) Bowers, whose pioneering work on education and environmental and sustainability issues is widely recognized and respected around the world, brings together a carefully curated selection of his seminal work on the ideological, cultural, and linguistic roots of the ecological crisis; misconceptions underlying modern consciousness; the cultural commons; a critique of technology; and educational reforms to address these pressing concerns. In the World Library of Educationalists, international scholars themselves compile career-long collections of what they judge to (...) be their finest pieces - extracts from books, key articles, salient research findings, major theoretical and/practical contributions - so the world can read them in a single manageable volume. Readers will be able to follow the themes and strands of their work and see their contribution to the development of a field, as well as the development of the field itself. Contributors to the series include : Michael Apple, James A. Banks, Joel Spring, William F. Pinar, Stephen J. Ball, Elliot Eisner, Howard Gardner, John Gilbert, Ivor F. Goodson, Peter Jarvis.

Ayahuasca is a psychoactive beverage that is mostly used in ritualized settings (Santo Daime rituals, neo-shamanic rituals, and even do-it-yourself-rituals). It is a common practice in the investigated socio-cultural field to call these settings “healing rituals.” For this study, 15 people who underwent ayahuasca (self-)therapy for a particular disease like chronic pain, cancer, asthma, depression, alcohol abuse, or Hepatitis C were interviewed twice about their subjective concepts and beliefs on ayahuasca and healing. Qualitative data analysis revealed a variety of motivational (...) patterns, subjective effects, and user types. Most participants were convinced that ayahuasca had influenced their illness positively or improved their coping with their illness. More importantly, it had enhanced their well being in general. As a result, we concluded that the effects of ayahuasca should not be reduced to a pharmacological model. The substance should be conceptualized as a psychological catalyst that unfolds within different fields of sociocultural ideas. (shrink)
Dr Ian Ramsey has made considerable use of the word ‘disclosure’ in what he has to say about religion and in his attempts to give an account of the meaning of religious language. He sometimes speaks of ‘discernment’ or ‘insight’ but ‘disclosure’ is the word he normally favours. In what follows I shall ask: what a disclosure is, to what extent Dr Ramsey's use of the notion leads to confusions, and what questions have to be faced in order to resolve (...) these confusions.

Peter Geach supports his case that the religion of Thomas Hobbes was both genuine and a version of Socinianism principally by comparing the theological and scriptural sections of Leviathan with the main doctrines of Socinianism and its latter-day developments in Unitarianism and Christadelphianism. He pays particular attention to comparisons with the Racovian Catechism, the theological writings of Joseph Priestley and the Christadelphian document Christendom Astray by Robert Roberts.
The ‘beautiful axiom’ to which Dickens refers is a central feature of Thomas Hobbes' thinking but its precise role in his moral philosophy remains unclear. I shall here attempt both to dispel the unclarity and to evaluate the adequacy of the position that emerges. Given the high level of contemporary interest in Hobbes' thought, both within and beyond philosophical circles, this is an enterprise of considerable importance. None the less, my interest is not merely interpretative, since the assessment of Hobbes' (...) attitude to ‘the beautiful axiom’ raises important and difficult questions about what might be termed the preconditions of morality.

This essay considers the relationship between the Bhagavad Gita as a transnational text and its changing role in Indian political thought. Indian liberals used it to mark out the boundaries between the public sphere they desired and a reformed Hinduism. Indian intellectuals also used the image of Krishna to construct an all-wise founder figure for the new India. Meanwhile, in the transnational sphere of debate, the Gita came to represent India itself in the works of theosophists, spiritual relativists and a (...) variety of intellectual radicals, who approved of the text's ambivalent view of the relationship between political action and the World Spirit. After the First World War, Indian liberals, notably Sarvepalli Radhakrishnan, philosopher and later India's second president, used Krishna's words to urge a new and humane international politics infused with the ideal of “detached action”.

In 1947 America’s premier philosopher, educator, and public intellectual John Dewey purportedly lost his last manuscript on modern philosophy in the back of a taxicab. Now, sixty-five years later, Dewey’s fresh and unpretentious take on the history and theory of knowledge is finally available. Editor Phillip Deen has taken on the task of editing Dewey’s unfinished work, carefully compiling the fragments and multiple drafts of each chapter that he discovered in the folders of the Dewey Papers at the Special (...) Collections Research Center at Southern Illinois University Carbondale. He has used Dewey’s last known outline for the manuscript, aiming to create a finished product that faithfully represents Dewey’s original intent. An introduction and editor’s notes by Deen and a foreword by Larry A. Hickman, director of the Center for Dewey Studies, frame this previously lost work. In Unmodern Philosophy and Modern Philosophy, Dewey argues that modern philosophy is anything but; instead, it retains the baggage of outdated and misguided philosophical traditions and dualisms carried forward from Greek and medieval traditions. Drawing on cultural anthropology, Dewey moves past the philosophical themes of the past, instead proposing a functional model of humanity as emotional, inquiring, purposive organisms embedded in a natural and cultural environment. Dewey begins by tracing the problematic history of philosophy, demonstrating how, from the time of the Greeks to the Empiricists and Rationalists, the subject has been mired in the search for immutable absolutes outside human experience and has relied on dualisms between mind and body, theory and practice, and the material and the ideal, ultimately dividing humanity from nature. The result, he posits, is the epistemological problem of how it is possible to have knowledge at all. In the second half of the volume, Dewey roots philosophy in the conflicting beliefs and cultural tensions of the human condition, maintaining that these issues are much more pertinent to philosophy and knowledge than the sharp dichotomies of the past and abstract questions of the body and mind. Ultimately, Dewey argues that the mind is not separate from the world, criticizes the denigration of practice in the name of theory, addresses the dualism between matter and ideals, and questions why the human and the natural were ever separated in philosophy. The result is a deeper understanding of the relationship among the scientific, the moral, and the aesthetic. More than just historically significant in its rediscovery, Unmodern Philosophy and Modern Philosophy provides an intriguing critique of the history of modern thought and a positive account of John Dewey’s naturalized theory of knowing. This volume marks a significant contribution to the history of American thought and finally resolves one of the mysteries of pragmatic philosophy. (shrink)
In an article in Philosophy R. G. Swinburne set out to argue that none of Hume's formal objections to the design argument ‘have any validity against a carefully articulated version of the argument’ . This, he maintained, is largely because Hume's criticisms ‘are bad criticisms of the argument in any form’ . The ensuing controversy between Swinburne and Olding 1 has focused upon the acceptable/unacceptable aspects of the dualism presupposed in Swinburne's defence of the design argument; upon whether any simplification (...) is achieved by reducing scientific explanation to agent explanation; and upon the problems which arise from taking a man's acting upon his body as the analogy for understanding a disembodied agent acting upon matter. In this article I shall refer to the Swinburne-Olding controversy when appropriate but my main concern is to return to Swinburne's original article and argue, seriatim , that Hume's individual criticisms of the design argument are for the most part a great deal more powerful than Swinburne allowed. I shall contend that cumulatively they destroy the design argument as any sort of rational foundation for theistic belief. But first I shall indicate briefly the character of the argument together with one or two of the distinctions and refinements in terms of which it has been found helpful to carry on the discussion in recent years.

In the past thirty years, two fundamental issues have emerged in the philosophy of science. One concerns the appropriate attitude we should take towards scientific theories--whether we should regard them as true or merely empirically adequate, for example. The other concerns the nature of scientific theories and models and how these might best be represented. In this ambitious book, da Costa and French bring these two issues together by arguing that theories and models should be regarded as partially rather than (...) wholly true. They adopt a framework that sheds new light on issues to do with belief, theory acceptance, and the realism-antirealism debate. The new machinery of "partial structures" that they develop offers a new perspective from which to view the nature of scientific models and their heuristic development. Their conclusions will be of wide interest to philosophers and historians of science. (shrink)
Our trust in the word of others is often dismissed as unworthy, because the illusory ideal of "autonomous knowledge" has prevailed in the debate about the nature of knowledge. Yet we are profoundly dependent on others for a vast amount of what any of us claim to know. Coady explores the nature of testimony in order to show how it might be justified as a source of knowledge, and uses the insights that he has developed to challenge certain widespread assumptions (...) in the areas of history, law, mathematics, and psychology.

A metafísica seria uma ciência real, entre outras razões, porque ela é uma ciência a posteriori. Este artigo pretende (...) verificar melhor a afirmação de que a metafísica de Suárez é uma ciência a posteriori. Pois, se de fato for assim, a interpretação realista que Rolf Darge oferece da metafísica de Suárez adquire maior plausibilidade. Palavras-chave: objeto da metafísica; empirismo; realismo. Is metaphysics an a priori or an a posteriori Science? Suárez and the foundation of metaphysics.: Against the interpretation of François Courtine, Rolf Darge affirms that for Francisco Suárez metaphysics is a science that deals not with being as that which can be an object for the human mind, but with being as that which is apt to actually exist. Metaphysics would be a real science, among other reasons, because it is a posteriori science. This article aims to verify the claim that Suárez's metaphysics is a posteriori science. If this is so, the realistic interpretation that Rolf Darge offers of Suárez's metaphysics acquires greater plausibility. Key-words: object of metaphysics; empiricism; realism.
