There has been considerable debate in the literature about the relative merits of information processing versus dynamical approaches to understanding cognitive processes. In this article, we explore the relationship between these two styles of explanation using a model agent evolved to solve a relational categorization task. Specifically, we separately analyze the operation of this agent using the mathematical tools of information theory and dynamical systems theory. Information-theoretic analysis reveals how task-relevant information flows through the system to be combined into a (...) categorization decision. Dynamical analysis reveals the key geometrical and temporal interrelationships underlying the categorization decision. Finally, we propose a framework for directly relating these two different styles of explanation and discuss the possible implications of our analysis for some of the ongoing debates in cognitive science.

Objectives - To explore the wvay ethical principles develop during a medical education course for three groups of medical students - in their first year, at the beginning of their penultimate (fifth) year and towards the end of their final (sixth) year. Design - Survey questionnaire administered to medical students in their first, fifth and final (sixth) year. Setting - A large medical school in Queensland, Australia. Survey sample - Approximately half the students in each of three years (first, fifth (...) and sixth) provided data on a voluntary basis, a total of 385 students. Results - At the point of entry, minor differences were found between medical students and first year law and psychology students. More striking were differences between male and female medical students, suggesting early socialization had a substantial impact here. Conclusions - Results indicate that substantial changes in attitude have developed by the beginning of fifth year with little change thereafter. Gender difference persisted. Some difference in ethical attitudes were found when groups of different ethnic backgrounds were compared. The impact of a move to a graduate medical course, which gives high priority to ethics within a professional development domain, can now be evaluated. (shrink)

A new methodology for developing theories of action has recently emerged which provides means for formally evaluating the correctness of such theories. Yet, for a theory of action to qualify as a solution to the frame problem, not only does it need to produce correct inferences, but moreover, it needs to derive these inferences from a concise representation of the domain at hand. The new methodology however offers no means for assessing conciseness. Such a formal account of conciseness is developed (...) in this paper. Combined with the existing criterion for correctness, our account of conciseness offers a framework where proposed solutions to the frame problem can be formally evaluated. (shrink)

Children in foster care are considered a “vulnerable population” in clinical care and research, with good reason. These children face multiple medical, psychological, and social risks that obligate the child welfare and healthcare systems to protect them from further harms. An unintended consequence of the “vulnerable population” designation for children in foster care is that it may impose barriers on tracking and studying their health that creates gaps in knowledge that are key to their receipt of medical care and good (...) outcomes. These gaps in knowledge have implications for justice, beneficence, and maleficence and serve to undermine “protection” of this population. Here we review the challenges of research regarding children in foster care, particularly medically complex children, and offer specific recommendations to include children in foster care in medical research.

Large-scale sequencing tests, including whole-exome and whole-genome sequencing, are rapidly moving into clinical use. Sequencing is already being used clinically to identify therapeutic opportunities for cancer patients who have run out of conventional treatment options, to help diagnose children with puzzling neurodevelopmental conditions, and to clarify appropriate drug choices and dosing in individuals. To evaluate and support clinical applications of these technologies, the National Human Genome Research Institute and National Cancer Institute have funded studies on clinical and research sequencing under (...) the Clinical Sequencing Exploratory Research program as well as studies on return of results. Most of these studies use sequencing in real-world clinical settings and collect data on both the application of sequencing and the impact of receiving genomic findings on study participants. They are occurring in the context of controversy over how to obtain consent for exome and genome sequencing. (shrink)

Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.

In lieu of an abstract, here is a brief excerpt of the content:Justice and the General Will:Affirming Rousseau's Ancient OrientationDavid Lay WilliamsThere is much confusion about how to characterize the work of Jean-Jacques Rousseau. His thought has at various times been related to such dissimilar thinkers as Plato and Hobbes. From Plato he is said to have acquired his affinities for community and civic virtue. And one does not have to look too hard to find his praise for the great (...) sage of the Academy: "Plato only purified the heart of man."1 He was often eager to affiliate his ideas with those of antiquity. He yearned for modern society to rekindle the flames of a once-great civilization. "[W]hat keeps us [the moderns] from being men like them [the ancients]? Our prejudices, our base philosophy, and the passions of petty self-interest, concentrated together with egoism in all hearts by inept institutions in which genius never had any share."2 Despite his obvious admiration for the perceived greater ideas of the past, however, Rousseau also expressed some skepticism. James Miller has suggested that he held Plato's theory of the Forms to be unsustainable.3 Allan Bloom has likewise argued that Rousseau's "teaching is not... a revival of those of Plato.... If he admires the practice of antiquity, he does not accept the theory."4This has led many to argue that Rousseau is best understood as student of Thomas Hobbes. Roger D. Masters, for example, has suggested that "Rousseau's principles of political right can... be best described as a reformulation [End Page 383] of Hobbes' conception of the social contract."5 Arthur Melzer also argues, "The purpose of the doctrine Rousseau elaborates in the Social Contract is essentially the same [as Hobbes']."6 This view is argued on the grounds that the General Will is a positive or arbitrary standard, functioning as the primary principle of Rousseau's constructive political program. Yet the vision of Rousseau as a Hobbesian or modernist also merits skepticism. While he employs a social contract, as does Hobbes, he explicitly rejects traditional forms of positivism. "What is good and conformable to order is so by the nature of things and independently of human conventions."7 Whatever one might say about such passages, it at least raises the possibility that Rousseau is no modernist in the Straussian sense of defining Justice as human agreement.Much of what contributes to the conflicting interpretations of Rousseau can be attributed to different understandings of the relative priority and relationship of two central concepts in his writings. One of these is the well-discussed notion of the General Will. The dominant fashion is to read the General Will as a conventional substitute for natural law or transcendent Ideas. According to this reading, the General Will is grounded on nothing more than consent and functions as the first principle of all legitimate political societies. The other term central to Rousseau's program is the far less discussed but equally important concept of Justice. Little has been written on his understanding of Justice and, for that matter, he himself rarely discussed it explicitly. But it, too, could also be considered a primary principle. While it would be foolish to dismiss the importance of the General Will to Rousseau, it would be equally problematic to explore it independently of his Idea of Justice. The question in understanding his work is which of these two principles—the General Will or Justice—is primary or fundamental. If it is the General Will, a case can be made that the Straussians are right, and Rousseau is a positivist. If Justice is prior, on the other hand, then there is reason to believe that he was something much different.I argue that the positivist reading of Rousseau is flawed. Indeed, my thesis is that he is among the greatest and most thorough Platonists of the modern era.8 His rejection of Hobbes is not merely rhetorical. In fact, it represents the [End Page 384] true impetus of his social contract. This contract is designed explicitly to counter Hobbesian positivism. In the same way that Plato responds to Protagoras' positivism with his theory of the Forms, Rousseau responds to Hobbes... (shrink)

It is clear from the above discussion that if I had wished to do so I could have truthfully presented every paper as either testing a prediction, presenting evidence needed in the test of a prediction, or presentin a D-N explanation. (I would not have been able to do this if I had not been sufficiently familiar with the evolutionary literature to recognize what hypotheses were at stake in several of the papers; even when the authors mention the hypotheses they (...) frequently do so only in enough detail to put their paper in context for the knowledgeable biologist.) Since these biologists are working in a period of normal science under the paradigm of the modern synthetic theory of evolution, none of these papers is presented as a test of the modern synthetic theory; but since this theory was used in the derivation of each prediction, each one is a test of it as well as of the hypothesis mentioned. Thus, once we learn to recognize the predictions beneath their cloaks of invisibility, we discover that prediction testing is not, as philosophers have claimed, at best peripheral to evolutionary biology; it is central to evolutionary biology.

This paper explores how medical practice ought to be conducted, in the face of scarcity, if our objective is to maximise the benefits of health. After explaining briefly what the cost-per-QALY criterion means, a series of ethical objections to it are considered one by one. The objectors fall into four groups: a. those who reject all collective priority-setting as unethical; b. those who accept the need for collective priority-setting, but believe it is contrary to medical ethics; c. those who accept (...) the need for collective priority-setting, and do not believe that it is contrary to medical ethics, but reject the role of QALYs in it; d. those who accept the need for collective priority-setting in principle, but are unwilling to specify how it should be done in practice. -/- The purpose of this discussion paper is to give each group a hard time!

Background: A high prevalence of cognitive impairment and frailty complicates the feasibility of advance care planning in the long-term-care population. Research aim: To identify challenges in implementing the ‘Let Me Decide’ advance care planning programme in long-term-care. Research design: This feasibility study had two phases: (1) staff education on advance care planning and (2) structured advance care planning by staff with residents and families. Participants and research context: long-term-care residents in two nursing homes and one community hospital. Ethical considerations: The (...) local research ethics committee granted ethical approval. Findings: Following implementation, over 50% of all residents had completed some form of end-of-life care plan. Of the 70 residents who died in the post-implementation period, 14% had no care plan, 10% (with capacity) completed an advance care directive and lacking such capacity, 76% had an end-of-life care plan completed for them by the medical team, following discussions with the resident (if able) and family. The considerable logistical challenge of releasing staff for training triggered development of an e-learning programme to facilitate training. Discussion: The challenges encountered were largely concerned with preserving resident’s autonomy, avoiding harm and suboptimal or crisis decision-making, and ensuring residents were treated fairly through optimisation of finite resources. Conclusions: Although it may be too late for many long-term-care residents to complete their own advance care directive, the ‘ Let Me Decide’ programme includes a feasible and acceptable option for structured end-of-life care planning for residents with variable capacity to complete an advance care directive, involving discussion with the resident (to the extent they were able) and their family. While end-of-life care planning was time-consuming to deliver, nursing staff were willing to overcome this and take ownership of the programme, once the benefits in improved communication and enhanced peace of mind among all parties involved became apparent in practice.

To date, there have been only two scholarly papers devoted to a comparison of Gestalt psychology with the psychology of William James. An early paper by Mary Whiton Calkins called attention to numerous similarities between these two schools of thought. However, a more recent paper by Mary Henle argues that the ideas of William James, as presented in The Principles of Psychology, are irrelevant to Gestalt psychology. In what follows, this claim is evaluated both in terms of The Principles and (...) Jamesís larger vision as set forth in his mature philosophical works. Although there are important differences between James and the Gestalt psychologists, there are also striking similarities particularly when the two schools are examined in the light of Jamesís mature philosophical perspectives.

This article criticizes Mathias Risse and Richard Zeckhauser's recent utilitarian defense of racial profiling. I use a novel thought-experiment to argue that even if a negative phenomenon could be reduced by profiling members of certain groups who happen to be disproportionately associated with it, the practice can be implausible. Specifically, I explore the possibility that in a given society, platinum blondes have a higher per capita incidence of a serious sexually transmitted disease, D. And I argue that doctors and health (...) officials in the society would not be justified in profiling such blondes, given that there is nothing about being a platinum blonde that causes one to have D.

Cet article examine la place du concept d’impartialité dans les théories délibératives de la démocratie. C’est à partir de certaines critiques féministes que sont discutés deux défis lancés à la théorie délibérative et qui sont étroitement liés : le premier porte essentiellement sur le critère du raisonnable et l’idée d’offre de raisons ; le second concerne les circonstances sociales et politiques contingentes dans lesquelles les perspectives des groupes marginalisés peuvent influencer le jugement des autres citoyens. Certains des changements qui devraient (...) être apportés à la théorie délibérative afin qu’elle puisse tenir compte de ces préoccupations sont ensuite proposés. Finalement, les implications de tels changements pour nos notions plus générales de vertu et de responsabilité de la citoyenneté sont examinées.This article examines the place of the concept of impartiality in theories of deliberative democracy. Drawing on and extending recent feminist critiques of deliberative democracy, it explores two interrelated challenges to deliberative theory, one focused on the standard of reasonableness and the idea of reason-giving and the other on the contingent social and political circumstances under which marginalized-groups perspectives may sway the judgment of other citizens. Finally, some of the changes required of deliberative theory to address these concerns are discussed, and the implications of these changes for our more general notions of the virtues and responsibilities of citizenship are explored.

L’érosion actuelle de la confiance du public envers les campagnes de vaccination et les décisions de politiques publiques qui y sont associées, aggravée par des scandales comme ceux relatifs à la pandémie H1N1 et l’utilisation du Tamiflu™, risque de diminuer de façon significative l’efficacité de ces interventions importantes pour la santé publique. Un manque de confiance de la population envers les acteurs de santé publique peut conduire à une méfiance accrue face aux interventions, pouvant ainsi compromettre l’atteinte des objectifs recherchés (...) par une intervention spécifique et, conséquemment, avoir un impact important sur les bénéfices attendus pour la population visée par cette intervention. Dans la production des avis d’experts, les membres des comités consultatifs d’experts en immunisation (CCEI) peuvent avoir une influence importante sur la prise de décision publique, notamment, sur la sélection par les décideurs de santé publique de vaccins en particulier et la façon dont les campagnes de vaccination seront déployées. En contrepartie de cette influence sur les décisions publiques, une indépendance et une transparence sont attendues de leur part puisque des mécanismes de divulgation et de gestion de conflits d’intérêts (CI) imparfaits peuvent affecter négativement la confiance du public à l’égard de telles décisions. Il apparaît donc important de s’assurer que des mécanismes de gestion des CI, transparents et robustes, existent pour ces comités. Dans cette étude, les avis ou rapports d’évaluation de la pertinence de la vaccination préparés par un CCEI au Québec ont été examinés pour quatre types de maladies évitables par la vaccination (infections invasives à méningocoques et à pneumocoques, coqueluche et virus du papillome humain). Le but était de : 1) identifier les CI divulgués par les membres du CCEI dans leurs rapports comparativement à ceux déclarés dans leurs publications scientifiques pour ces mêmes infections ; 2) analyser la nature des CI (réel, potentiel, apparent, personnel, financier, institutionnel, etc.) et l’impact potentiel (risque) sur la prise de décision impartiale et sur la confiance du public ; et 3) évaluer les mécanismes de gestion de CI actuellement utilisés par ce CCEI. Les résultats de cette étude montrent que très peu de rapports du CCEI contiennent une section sur les CI par rapport à la pléthore divulguée dans les publications scientifiques publiées par les membres du CCEI. De plus, les CI divulgués dans les rapports fréquemment ne correspondent pas à ceux décrits dans les publications scientifiques. Il serait donc important d’introduire des mesures visant à accroître la transparence des experts en immunisation et d’améliorer les mécanismes de divulgation et de gestion des CI afin de veiller à ce que la confiance du public envers les décideurs en santé publique soit maintenue et améliorée.

The return of genetic research results after death in the pediatric setting comes with unique complexities. Researchers must determine which results and through which processes results are returned. This paper discusses the experience over 15 years in pediatric cancer genetics research of returning research results after the death of a child and proposes a preventive ethics approach to protocol development in order to improve the quality of return of results in pediatric genomic settings.

The philosophy of cognitive science has recently become one of the most exciting and fastest growing domains of philosophical inquiry and analysis. Until the early 1980s, nearly all of the models developed treated cognitive processes -- like problem solving, language comprehension, memory, and higher visual processing -- as rule-governed symbol manipulation. However, this situation has changed dramatically over the last half dozen years. In that period there has been an enormous shift of attention toward connectionist models of cognition that are (...) inspired by the network-like architecture of the brain. Because of their unique architecture and style of processing, connectionist systems are generally regarded as radically different from the more traditional symbol manipulation models. This collection was designed to provide philosophers who have been working in the area of cognitive science with a forum for expressing their views on these recent developments. Because the symbol-manipulating paradigm has been so important to the work of contemporary philosophers, many have watched the emergence of connectionism with considerable interest. The contributors take very different stands toward connectionism, but all agree that the potential exists for a radical shift in the way many philosophers think of various aspects of cognition. Exploring this potential and other philosophical dimensions of connectionist research is the aim of this volume. (shrink)

This book is a systematic reconstruction of Heidegger's account of time and temporality in Being and Time. The author locates Heidegger in a tradition of 'temporal idealism' with its sources in Plotinus, Leibniz, and Kant. For Heidegger, time can only be explained in terms of 'originary temporality', a concept integral to his ontology. Blattner sets out not only the foundations of Heidegger's ontology, but also his phenomenology of the experience of time. Focusing on a neglected but central aspect of Being (...) and Time, this book will be of considerable interest to all students of Heidegger both inside and outside philosophy. (shrink)

The field of AI safety aims to prevent increasingly capable artificially intelligent systems from causing humans harm. Research on moral alignment is widely thought to offer a promising safety strategy: if we can equip AI systems with appropriate ethical rules, according to this line of thought, they'll be unlikely to disempower, destroy or otherwise seriously harm us. Deontological morality looks like a particularly attractive candidate for an alignment target, given its popularity, relative technical tractability and commitment to harm-avoidance principles. I (...) argue that the connection between moral alignment and safe behavior is more tenuous than many have hoped. In general, AI systems can possess either of these properties in the absence of the other, and we should favor safety when the two conflict. In particular, advanced AI systems governed by standard versions of deontology need not be especially safe. (shrink)

In terms of control of composition, the fabrication of money was arguably the most demanding of all pre-Industrial Revolution metallurgical practices. The calculations involved in such control needed arithmetical computations involving repeated multiplications and divisions, not only of integers but also of mixed numbers. Such computations were possible using Roman numerals, but with some difficulties. The advantages gained by employing arithmetic using Indo-arabic numerals for alloying calculations would have been the same as for other types of commercial calculations. A method (...) of calculating the proportions of two coinage alloys of different compositions that were needed to produce a third alloy of specified intermediate composition, eventually known as the rule of alternate alligation, was however, a specific requirement in the minting of money. This requirement made a particular demand on medieval mathematics, as a solution was not possible using arithmetic alone. Furthermore, the problem became indeterminate when more than two components were available for mixing. All the necessary methods of calculation were described by Fibonacci in his Liber abbaci. These methods are to be found in a sequence of practical arithmetics that stretch through the trattati d'abbaco of the Italian city states during the fourteenth and fifteenth centuries, to the first printed books of Continental authors such as Pacioli. Of the earliest sixteenth-century printed English books on practical arithmetic, The Grounde of Artes by Robert Recorde contained the first advance in the methodology of alternate alligation since Fibonacci. In the seventeenth century, formal proof of the rule of alternate alligation was given by Kersey in his practical arithmetics and his treatise on algebra. The topic was also addressed by several authors of academic algebras. It was in this century that the problem of indeterminacy in the solution of alternate alligation involving the mixture of more than two components, was finally resolved. English mint accounts provide little direct information on the alloying calculations carried out, and nothing on the methods used. However, the continued description of such calculations in other mint documents, merchants notebooks, and in goldsmiths' handbooks spanning four centuries imply that the calculations described in practical arithmetics were used in practice. Monetary matters had high economic and political profiles during the whole of the time span covered in this study. The influence of such considerations pervades the history of the technology of minting and the mathematics on which it called, and is discussed in context. (shrink)

Distinctive features of culture industries suggest that women culture workers face formidable barriers to career advancement. Using longitudinal data on the careers of screenwriters, we examine gender inequality in the labor market for writers of feature films. We hypothesize and test three different models of labor market dynamics and find support for a model of cumulative disadvantage whereby the gender gap in earnings grows as men and women move through their careers. We suggest that the transition of screenwriting from a (...) mixed to a male-dominated occupation parallels the “empty field” phenomenon described in a study by Tuchman of nineteenth-century novelists. The institutionalization of male dominance of the film industry in the 1930s and the typecasting of women writers has had a lasting impact on gender inequality, which shows little change through the early 1990s.

In lieu of an abstract, here is a brief excerpt of the content:What Do You Mean, Rhetoric Is Epistemic?William D. HarpineIn 1967, Robert L. Scott (1967) advocated that "rhetoric is epistemic." This concept has enriched the work of rhetorical theorists and critics. Scott's essay is founded in a concept of argumentative justification in rhetoric, viewed as an alternative to analytic logic. Other writers, including Brummett (1976), Railsback (1983), and Cherwitz and Hikins (1986), have offered variations on Scott's theme. The thesis (...) that rhetoric is epistemic has been controversial, however, and from the tone of the debate one may draw two conclusions: many rhetorical theorists feel that Scott was on to something important, and the thesis as it has been developed is flawed. Much of the dispute centers on what the thesis means. These discussions have not yet adequately clarified that issue.The philosopher's most fundamental obligation is to define terms with care. It is in precisely this respect that the rhetoric-is-epistemic theorists have fallen short. Some of the key terms in this literature include rhetoric, knowledge, certainty, and truth. In too many cases, the writers on rhetorical epistemology have not defined their key terms at all. In other cases, their definitions are inadequate or inconsistent. This essay undertakes to sort out the most important definitional problems, which center on the rhetoric-is-epistemic theorists' habit of equivocating about the meanings of "rhetoric" and "certainty." The result makes it possible to endorse the validity of Scott's essentially ethical conclusions, while dismissing a number of unnecessary complexities in the arguments made by rhetoric-as-epistemic theorists. Finally, a few alternatives that might lead to more robust foundations for the rhetoric-as-epistemic thesis are suggested.In 1978, after reviewing four distinct interpretations of the claim that rhetoric is epistemic, Leff concluded that clarification of what that claim means "deserves more disciplined treatment than it has received in the recent literature" (1978, 77). The same could still be said. After some [End Page 335] thirty years of active research and speculation on the topic, one now sees fewer publications specifically advocating that rhetoric is epistemic. The distinguished rhetorical theorist Barry Brummett (1990) has declared the thesis deceased (69-72).All the same, textbook authors treat the thesis as a given, despite their tendency to interpret it in wildly different ways. Foss, for example, puts forward a view that "in the field of communication, the idea that rhetoric creates reality is known as the notion that rhetoric is epistemic, which simply means that rhetoric creates knowledge; epistemology is the study of the origin and nature of knowledge" (1989, 122; emphasis in the original). This version of the thesis, claiming that rhetoric actually "creates reality," might be more ontological than it is epistemic.1 Herrick takes a dialectical view that "through rhetorical interaction, people come to accept some ideas as true and to reject others as false. Thus, rhetoric's epistemic function in society can be seen in some ways to be a result of its benefit of testing ideas." Herrick continues that "once an idea has been tested thoroughly by a group, community, and society, it becomes part of what these groups take to be knowledge." Herrick contrasts this with the rejected view that "knowledge is all objective in nature and comes to us by way of direct experience or education" (1997, 22). Both Herrick and Foss offer interesting theses, and both attribute their views to Scott, but their views are obviously very different. There can be no surer evidence of the failure to use terms precisely.Brummett (1990) attributes the demise of rhetoric-is-epistemic research to the failure of critics to employ the idea in rhetorical criticism. Brummett might be right to the extent that much of the rhetoric-is-epistemic literature is indeed exceptionally abstract. Specific discussions might clarify some issues. Nonetheless, some notable rhetorical critics have indeed employed a concept that rhetoric is epistemic (e.g., Scott and Klumpp 1984; Sullivan 1992). The issues remain unclear. Furthermore, rhetorical criticism per se cannot clarify the meanings of theoretical terms. More likely, one sees less and less published research about the thesis that rhetoric is epistemic precisely because the thesis has not been laid out clearly... (shrink)
