Given a set of objects characterized by a number of attributes, hidden patterns can be discovered in them for the grouping of similar objects into clusters. If each of these clusters can be considered as exemplifying a certain concept, then the problem concerned can be referred to as a concept discovery problem. This concept discovery problem can be solved to some extent by existing data clustering techniques. However, they may not be applicable when the concept involved is vague in nature (...) or when the attributes characterizing the objects can be qualitative, quantitative, and fuzzy at the same time. To discover such concepts from objects with such characteristics, we propose a Genetic-Algorithm-based technique. By encoding a specific object grouping in a chromosome and a fitness measure to evaluate the cluster quality, the proposed technique is able to discover meaningful fuzzy clusters and assign membership degrees to objects that do not fully exemplify a certain concept. For evaluation, we tested the proposed technique with simulated and real data and the results are found to be very promising. (shrink)

First published in 1992, this book represents the first major attempt to compile a bibliography of Derrida’s work and scholarship about his work. It attempts to be comprehensive rather than selective, listing primary and secondary works from the year of Derrida’s Master’s thesis in 1954 up until 1991, and is extensively annotated. It arranges under article type a huge number of works from scholars across numerous fields — reflecting the interdisciplinary and controversial nature of Deconstruction. The substantial introduction and annotations (...) also make this bibliography, in part, a critical guide and as such will make a highly useful reference tool for those studying his philosophy.

Two articles by Lewis Feuer caught my attention in the '40s when 1 was wondering, asa student physicist, about the relations of physics to philosophy and to the world in turmoil. One was his essay on 'The Development of Logical Empiricism' (1941), and the other his critical review of Philipp Frank's biography of Einstein, 'Philosophy and the Theory of Relativity' (1947). How extraordinary it was to find so intelligent, independent, critical, and humane a mind; and furthermore he went further, (...) as I soon realized when I looked for his name on other publications. I recall arguing with myself over his exploration of 'Indeterminacy and Economic Development' (1948), and even more when I read his 'Dialectical Materialism and Soviet Science' (1949). More papers, and then the fascinating, sometimes irritating, always insightful, books. His monograph on Psychoanalysis and Ethics 1955, the beautiful sociological and humanist study of Spinoza and the Rise of Liberalism (1958), his essays on 'The Social Roots of Einstein's Theory of Relativity' (1971) together with the book on Einstein and the Genera tions of Science (1974), the splendid reader from the works of Marx and Engels, Basic Writings on Politics and Philosophy (1959) which was a major text of the '60s, the stimulating essays on the social formation which seems to have been required for a modern scientific movement to develop, set forth most convincingly in The Scientific Intellectual (1963).

Court D. Lewis, author of Repentance and the Right to Forgiveness, presents a rights-based theory of ethics grounded in eirenéism, a needs-based theory of rights (inspired by Nicholas Wolterstorff) that seeks peaceful flourishing for all moral agents. This approach creates a moral relationship between victims and wrongdoers such that wrongdoers owe victims compensatory obligations. However, one further result is that wrongdoers may be owed forgiveness by victims. This leads to the “repugnant implication” that victims may be wrongdoers who do (...) not forgive. Author Lewis addresses the “repugnant implication” by showing that victims are obligated to work toward forgiveness, if not forgiveness itself. Critic Gregory L. Bock argues that victims are not the only ones who can forgive, that the personal dimensions of forgiveness are overlooked, and that the force of the “repugnancy implication” may be questioned. Instead of rights-based eirenéism, Bock supports a virtue ethics framework. Instead of rights-based eirenéism, Bock encourages virtue ethics. Critic David Boersema raises questions about the binding nature of relationships, the dependency of flourishing upon forgiveness, and the nature of needs or rights. Boersema also questions the wisdom of a rights-based approach to forgiveness. Critic Jennifer Kling asks whether a rights-based approach is necessary to ground obligations to meet the needs of others: why not an ethics of care? If a rights-based approach is taken, perhaps a wrongdoer is obligated to not make forgiveness a life good. By disengaging this obligation, we avoid constraining a victim’s work toward forgiveness, especially when the wrongdoing is oppressive. Author Lewis responds to these objections. (shrink)

Alongside concerns for animal welfare, concerns for land, water, and climate are undermining established food identities in many parts of the world. In Aotearoa New Zealand, agrifood relations are bound tightly into national identities and the materialities of export dependence on dairying and agriculture more widely. Dairy/ing identities have been central to national development projects and the politics that underpin them for much of New Zealand’s history. They are central to an intransigent agrifood political ontology. For the last decade, however, (...) they have been challenged by the identity politics of ethical food consumption. This paper explores the ensuing contests and asks how they are reshaping agrifood identities. We draw on interviews with 15 participants in Aotearoa New Zealand who have made dietary transitions that reduce or exclude dairy products. Our aim is not to identify a new post-dairying identity or claim a reconfigured national identity, but to examine the collision of production-consumption values in the context of a dominant place-based food identity. We ask how participants navigate contradictory commitments to becoming ‘good environmental citizens’ whilst remaining ‘good national citizens’. The paper offers insights for examining similar struggles elsewhere and the potential to shift agrifood relations and undermine entrenched political ontologies through ethical food consumption values.

We propose a framework for including information‐processing bounds in rational analyses. It is an application of bounded optimality (Russell & Subramanian, 1995) to the challenges of developing theories of mechanism and behavior. The framework is based on the idea that behaviors are generated by cognitive mechanisms that are adapted to the structure of not only the environment but also the mind and brain itself. We call the framework computational rationality to emphasize the incorporation of computational mechanism into the definition of (...) rational action. Theories are specified as optimal program problems, defined by an adaptation environment, a bounded machine, and a utility function. Such theories yield different classes of explanation, depending on the extent to which they emphasize adaptation to bounds, and adaptation to some ecology that differs from the immediate local environment. We illustrate this variation with examples from three domains: visual attention in a linguistic task, manual response ordering, and reasoning. We explore the relation of this framework to existing “levels” approaches to explanation, and to other optimality‐based modeling approaches. (shrink)

All the authors of the sixteen essays gathered in this volume are concerned, in their different ways, to clarify, criticize, and develop key ideas and insights of Alfred North Whitehead (1861-1947), one of the towering figures of twentieth-century speculative thought, whose "process philosophy" has, in recent decades, aroused intense intellectual interest both in this country and abroad. The present volume is intended to complement, but not to duplicate, an earlier selection of important Whitehead studies, Alfred North Whitehead: Essays on His (...) Philosophy, ed. G. L. Kline (Englewood Cliffs: Prentice Hall, 1963). (shrink)

In our recent article, together with more than 60 of our colleagues, we outlined a proposal for drug policy reform consisting of four specific yet interrelated strategies: (1) de jure decriminalization of all psychoactive substances currently deemed illicit for personal use or possession (so-called “recreational” drugs), accompanied by harm reduction policies and initiatives akin to the Portugal model; (2) expunging criminal convictions for nonviolent offenses pertaining to the use or possession of small quantities of such drugs (and releasing those serving (...) time for these offenses), while delivering retroactive ameliorative relief; (3) the ultimate legalization and careful regulation of currently illicit drugs; and (4) the delivery of a new “Marshall Plan” focused on community-building initiatives, expanded harm reduction programs, and social and health care support efforts (Earp et al. 2021). We were gratified to see so many thoughtful commentaries on our proposal, and we respond to them in part in this reply. (shrink)

This book provides a variety of diverse perspectives related to the ethics of anger, some more analytical in nature, others focused on practical issues, some in defense of anger, and others arguing against its necessity. This book is an essential resource for scholars who want to reflect critically on the place of anger in contemporary life.

We explore the idea that eye-movement strategies in reading are precisely adapted to the joint constraints of task structure, task payoff, and processing architecture. We present a model of saccadic control that separates a parametric control policy space from a parametric machine architecture, the latter based on a small set of assumptions derived from research on eye movements in reading (Engbert, Nuthmann, Richter, & Kliegl, 2005; Reichle, Warren, & McConnell, 2009). The eye-control model is embedded in a decision architecture (a (...) machine and policy space) that is capable of performing a simple linguistic task integrating information across saccades. Model predictions are derived by jointly optimizing the control of eye movements and task decisions under payoffs that quantitatively express different desired speed-accuracy trade-offs. The model yields distinct eye-movement predictions for the same task under different payoffs, including single-fixation durations, frequency effects, accuracy effects, and list position effects, and their modulation by task payoff. The predictions are compared to—and found to accord with—eye-movement data obtained from human participants performing the same task under the same payoffs, but they are found not to accord as well when the assumptions concerning payoff optimization and processing architecture are varied. These results extend work on rational analysis of oculomotor control and adaptation of reading strategy (Bicknell & Levy, ; McConkie, Rayner, & Wilson, 1973; Norris, 2009; Wotschack, 2009) by providing evidence for adaptation at low levels of saccadic control that is shaped by quantitatively varying task demands and the dynamics of processing architecture.

By their very nature, overseas medical missions (and even domestic medical charities such as free clinics ) are designed to serve vulnerable populations. If these groups were capable of protecting their own interests, they would not need the help of medical volunteers: their medical needs would be met through existing government health programs or by utilizing their own resources. Medical volunteerism thus seems like an unfettered good: a charitable activity provided by well-meaning doctors and nurses who want to give of (...) their time, skills, and resources to help those who would not otherwise be able to take care of their medical needs. In this article, I argue that if medical volunteerism is to be good, however, it must always meet certain basic ethical requirements. These requirements may be (and perhaps often are) overlooked in the rush to organize and carry out short-term medical missions. I illustrate my point with special reference to short-term medical missions designed to provide surgical repair of obstetric vesico-vaginal fistula, a condition in which the tissues that normally separate the bladder from the vagina are destroyed by obstetric trauma, leading to continuous and unremitting incontinence in the affected woman.

Historically, laws and policies to criminalize drug use or possession were rooted in explicit racism, and they continue to wreak havoc on certain racialized communities. We are a group of bioethicists, drug experts, legal scholars, criminal justice researchers, sociologists, psychologists, and other allied professionals who have come together in support of a policy proposal that is evidence-based and ethically recommended. We call for the immediate decriminalization of all so-called recreational drugs and, ultimately, for their timely and appropriate legal regulation. We (...) also call for criminal convictions for nonviolent offenses pertaining to the use or possession of small quantities of such drugs to be expunged, and for those currently serving time for these offenses to be released. In effect, we call for an end to the “war on drugs.”. (shrink)

A promising approach to more refined models consistent with the Caplan & Waters hypothesis is based on similarity-based interference, a general principle that applies across working memory domains. This may explain both the fine details of syntactic working memory phenomena and the gross fractionation for which Caplan & Waters have found evidence. Detailed models of syntactic processing that embody similarity-based interference fare well cross-linguistically.
