An important application of cognitive architectures is to provide human performance models that capture psychological mechanisms in a form that can be “programmed” to predict task performance of human–machine system designs. Although many aspects of human performance have been successfully modeled in this approach, accounting for multitalker speech task performance is a novel problem. This article presents a model for performance in a two-talker task that incorporates concepts from psychoacoustics, in particular, masking effects and stream formation.
What kind of knowledge is medical knowledge? Can medicine be explained scientifically? Is disease a scientific concept, or do explanations of disease depend on values? What is ‘evidence-based’ medicine? Are advances in neuroscience bringing us closer to a scientific understanding of the mind? The nature of medicine raises fundamental questions about explanation, causation, knowledge and ontology – questions that are central to philosophy as well as medicine. In this book Paul R. Thompson and Ross E. G. Upshur introduce the (...) fundamental issues in philosophy of medicine for those coming to the subject for the first time. They introduce and explain the following key topics: Understanding the physician-patient relationship: the phenomenology of the medical encounter. Models and theories in biology and medicine: what role do theories play in medicine? Are they similar to scientific theories? Randomised controlled trials: can scientific experiments be replicated in clinical medicine? What are the philosophical criticisms levelled at RCTs? The concept of evidence in medical research: what do we mean by ‘Evidence-based medicine?’ Should all medicine be based on evidence? Causation in medicine What do advances in neuroscience reveal about the relationship between mind and body? Defining health and disease: are explanations of disease objective or do they depend on values? Evolutionary medicine: what is the role of evolutionary biology in understanding medicine? Is it relevant? Extensive use of empirical examples and case studies is made throughout the book. These include debates about smoking and cancer, the use of placebos in randomised controlled trials and controversies about research into the causes of HIV and autism. This is an indispendable introduction to those teaching philosophy of medicine and philosophy of science. (shrink)
This paper explores R. D. Laing's application of existential and phenomenological tradtions, specifically Hegel and Heidegger, to his groundbreaking work with psychotic process as well as psychotherapeutic practice more generally.
The Politics of the Soul: Eric Voegelin on Religious Experience includes eight essays examining one of the most profound studies of religious experience to appear in the last century: that of the political philosopher Eric Voegelin. Voegelin is increasingly recognized as a political theorist of exceptional scope and erudition and the most important philosopher of his time since Toynbee, and his treatment of religious experience is a crucial part of his overall analysis of existence and history. This collection (...) of essays by prominenet Voegelin scholars is the first book to explore the relevance of that analysis to the contemporary understanding of political theory, theology, history, and philosophy of consciousness, and as such it constitutes a significant contribution not only to Voegelin scholarship but to the current quest for theoretical foundations.

We show that at each type k ≥ 2, there exist c-irreducible functionals of c-r.e. degree, as defined in [Nor 1]. Our proofs are based on arguments due to Hinman, [Hin 1], and Dvornikov, [Dvo 1].
Michael Berry, Professor of Physics at Bristol University, discusses the philosophical ideas underlying his research to the theories of catastrophes and chaotic systems. He is one of England's leading scientists, and has been instrumental in the growth of interest in qualitative phenomena.
b>. Computational models of colour vision assume that the biological function of colour vision is to detect surface reflectance. Some philosophers invoke these models as a basis for 'externalism' about perceptual content (content is distal) and 'objectivism' about colour (colour is surface reflectance). In an earlier article (Thompson et al. 1992), I criticized the 'computational objectivist' position on the basis of comparative colour vision: There are fundmental differences among the colour vision of animals and these differences do not converge (...) on the detection of any single type of environmental property. David R. Hilbert (1992) has recently defended computational objectivism against my 'comparative argument;' his arguments are based on the externalist approach to perceptual content originally developed by Mohan Matthen (1988) and on the computationally inspired theory of the evolutionary basis for trichromacy developed by Roger N. Shepard (1990). The present article provides a reply to Hilbert with extensive criticism of both Matthen's and Shepard's theories. I argue that the biological function of colour vision is not to detect surface reflectance, but to provide a set of perceptual categories that can apply to objects in a stable way in a variety of conditions. Comparative research indicates that both the perceptual categories and the distal stimuli will differ according to the animal and its visual ecology; therefore externalism and objectivism must be rejected.

Thomas Chubb seems to have been an 18th century English artisan class version of Eric Hoffer. Only the subject for Chubb was Deism rather than democracy. This is not, of course, to deny the link between these two, a link which is accented to some extent in Chubb's own work. Bushell has given us a short biographical account of Chubb together with six chapters that dutifully comb Chubb's moral, political, and, especially, his theological writings for a synthetic view of (...) Chubb's opinion on such subjects as the historical Jesus, theodicy, providence, toleration, and natural law. Chubb seems to have attracted the curiosity of the intelligensia [[sic]] of his own and later times. But, on balance, he does not appear to be even a major minor figure.--E. A. R. (shrink)
This is the first new edition of the Meno with English commentary and annotation since Thompson's in 1901. Dr. Bluck brings to bear more recent scholarship in his commentary and notes, which are judicious and thorough; and his new collations help to make the text the best available. Any account of the Meno's truth and meaning should begin with the careful textual, philological, logical, and historical considerations of the commentary and introduction of this new edition.--R. S.

Despite the lament of the decline and even the death of political theory, Germino contends that "the revival of political theory is one of the momentous intellectual and cultural developments of our time." The neglect of this revival is, in part, due to the myopia and false conception of political theory by modern political scientists and positivistically orientated philosophers. After criticizing the proponents of the "alleged decline" of political theory, Germino sketches a view of political theory as a tradition of (...) inquiry practiced by the great political theorists from Plato to Hegel. He both describes and criticizes the assault upon political theory by such thinkers as Tracy, Comte, and Marx. The revival of political theory in the grand manner is to be found in such representatives as Oakeshott, Arendt, Jouvenel, and Strauss. It is Eric Voegelin that is the true hero of this revival, and despite his neglect, Germino suggests that later generations may well acclaim Voegelin "as the greatest political theorist of our time." This is a book with a strong positive thesis, and Germino balances developing stages in his argument with expositions of the positions that he both attacks and defends. There is a growing sympathy among both philosophers and political scientists for the defense of the viability of political theory developed in this book, although many of those sympathetic with the thesis may feel that sharper and more penetrating criticism is needed to defend the thesis, and may not share Germino's enthusiasm for Voegelin.--R.

Humans have been modifying plants and animals for millennia. The dawn of molecular genetics, however, has kindled intense public scrutiny and controversy. Crops, and the food products which include them, have dominated molecular modification in agriculture. Organisations have made unsubstantiated claims and scare mongering is common. In this textbook Paul Thompson presents a clear account of the significant issues - identifying harms and benefits, analysing and managing risk - which lie beneath the cacophony of public controversy. His comprehensive analysis (...) looks especially at genetically modified organisms, and includes an explanation of the scientific background, an analysis of ideological objections, a discussion of legal and ethical concerns, a suggested alternative - organic agriculture - and an examination of the controversy's impact on sub-Saharan African countries. His book will be of interest to students and other readers in philosophy, biology, biotechnology and public policy. (shrink)
Public health advocates, government agencies, and commercial organizations increasingly use nutritional science to guide food choice and diet as a way of promoting health, preventing disease, or marketing products. We argue that in many instances such references to nutritional science can be characterized as nutritional scientism. We examine three manifestations of nutritional scientism: the simplification of complex science to increase the persuasiveness of dietary guidance, superficial and honorific references to science in order to justify cultural or ideological views about food (...) and health, and the presumption that nutrition is the primary value of food. This paper examines these forms of nutritional scientism in the context of biopolitics to address bioethical concerns related to the misuse of scientific evidence to make claims regarding the effect of diet on health. We argue that nutritional scientism has ethical implications for individual responsibility and freedom, concerning iatrogenic harm, and for well-being. (shrink)
Engagement happens when academics and non-academics form partnerships to create mutual understanding, and then take action together. An example is the “value web” work associated with W. K. Kellogg Foundation’s Food Systems Higher Education–Community Partnership. Partners nationally work on local food systems development by building value webs. “Value chains,” a concept with considerable currency in the private sector, involves creating non-hierarchical relationships among otherwise disparate actors and entities to achieve collective common goals. The value web concept is extended herein by (...) separating the values of the web itself, such as the value of collaboration, from values “in” the web, such as credence values associated with a product or service. By sharing and discussing case examples of work underway around the United States, the authors make a case for employing the value webs concept to represent a strategy for local food systems development, specifically, and for higher education–community partnerships, generally.

Dimensions of character are often overlooked in professional practice at the expense of the development of technical competence and operational efficiency. Drawing on philosophical accounts of virtue ethics and positive psychology, the present work attempts to elevate the role of ‘good’ character in the professional domain. A ‘good’ professional is ideally one that exemplifies dimensions of character informed by sound judgement. A total of 2340 professionals, from five discrete professions, were profiled based on their valuation of qualities pertaining to character (...) and judgement. Profile differences were subsequently examined in the self-reported experience of professional purpose towards a wider societal ‘good’. Analysis of covariance, controlling for stage of career, revealed that professionals valuing character reported higher professional purpose than those overweighting the importance of judgement or valuing neither character nor judgement, F = 7.92, p <.001. No differences were found between the two groups valuing character, irrespective of whether judgement was valued simultaneously. This profiling analysis of entry-level and in-service professionals, based on their holistic character composition, paves the way for fresh philosophical discussion regarding what constitutes a ‘good’ professional and the interplay between character and judgement. The empirical findings may be of substantive value in helping to recognise how the dimensions of character and judgement may impact upon practitioners’ professional purpose. (shrink)
This paper presents students’ views about honest and dishonest actions within the pharmacy and medical learning environments. Students also offered their views on solutions to ameliorating dishonest action. Three research questions were posed in this paper: (1) what reasons would students articulate in reference to engaging in dishonest behaviours? (2) What reasons would students articulate in reference to maintaining high levels of integrity? (3) What strategies would students suggest to decrease engagement in dishonest behaviours and/or promote honest behaviours? The design (...) of the study incorporated an initial descriptive analysis to interpret students’ responses to an 18-item questionnaire about justifications for dishonest action. This was followed by a qualitative analysis of students’ commentaries in reference to why students would engage in either honest or dishonest action. Finally a qualitative analysis was conducted on students’ views regarding solutions to dishonest action. The quantitative results showed that students were more likely to use time management and seriousness justifications for dishonest actions. The qualitative findings found that students’ actions (honest or dishonest) were guided by family and friends, the need to do well, issues of morality and institutional guidelines. Students suggested that dishonest action could be ameliorated by external agencies and polarised views between punitive and rewards-based mechanisms were offered. These results suggest that these students engaged in dishonest action for various reasons and solutions addressing dishonest action need to consider diverse mechanisms that likely extend beyond the educational institution.
