The majority of food in the US is distributed through global/national supply chains that exclude locally-produced goods. This situation offers opportunities to increase local food production and consumption and is influenced by constraints that limit the scale of these activities. We conducted a study to assess perspectives of producers and consumers engaged in food systems of a major Midwestern city. We examined producers’ willingness to include/increase cultivation of local foods and consumers’ interest in purchasing/increasing local foods. We used focus groups (...) of producers (two groups of conventional farmers, four local food producers) and consumers (three conventional market participants, two locavores) to pose questions about production/consumption of local foods. We transcribed discussions verbatim and examined text to identify themes, using separate affinity diagrams for producers and consumers. We found producers and consumers are influenced by the _status quo_ and real and perceived barriers to local foods. We also learned participants believed increasing production and consumption of local foods would benefit their community and creating better infrastructure could enhance efforts to scale up local food systems. Focus group participants also indicated support from external champions/programs could support expansion of local foods. We learned that diversifying local food production was viewed as a way to support local community, increase access to healthy foods and reduce environmental impacts of conventional production. Our research indicates that encouraging producers and consumers in local food systems will be more successful when support for the local community is emphasized. (shrink)

PurposeTo use the power of knowledge acquisition and machine learning in the development of a collaborative computer classification system based on the features of age-related macular degeneration (AMD).MethodsA vocabulary was acquired from four AMD experts who examined 100 ophthalmoscopic images. The vocabulary was analyzed, hierarchically structured, and incorporated into a collaborative computer classification system called IDOCS. Using this system, three of the experts examined images from a second set of digital images compiled from more than 1000 patients with AMD. Images (...) were annotated, and features were identified and defined. Decision trees, a machine learning method, were trained on the data collected and used to extract patterns. Interrelationships between the data from the different clinicians were investigated.ResultsSix drusen classes in the structured vocabulary were largely sufficient to describe all the identified features. The decision trees classified the data with 76.86% to 88.5% accuracy and distilled patterns in the form of hierarchical trees composed of 5 to 15 nodes. Experts were largely consistent in their characterization of soft, and to a lesser extent, hard drusen, but diverge in definition of other drusen. Size and crystalline morphology were the main determinants of drusen type across all experts.ConclusionsMachine learning is a powerful tool for the characterization of disease phenotypes. The creation of a defined feature set for AMD will facilitate the development of an IDOCS-based classification system. (shrink)

We explore the nature of forgetting in a corpus of 125,000 students learning Spanish using the Rosetta Stone® foreign-language instruction software across 48 lessons. Students are tested on a lesson after its initial study and are then retested after a variable time lag. We observe forgetting consistent with power function decay at a rate that varies across lessons but not across students. We find that lessons which are better learned initially are forgotten more slowly, a correlation which likely reflects (...) a latent cause such as the quality or difficulty of the lesson. We obtain improved predictive accuracy of the forgetting model by augmenting it with features that encode characteristics of a student's initial study of the lesson and the activities the student engaged in between the initial and delayed tests. The augmented model can predict 23.9% of the variance in an individual's score on the delayed test. We analyze which features best explain individual performance. (shrink)

This paper discusses the philosophical doctrine of moral luck, as described by Bernard Williams in his book of the same name. It first describes Williams' account and then uses the case of Michael Stone, a convicted murderer with a long history of mental disorder, and mental health practitioners’ interventions in his case, to test and debate Williams’ views. It examines four major areas of these, including the classical notion of moral luck, retroactive judgement, agent regret and justifiable and (...) unjustifiable decision‐making. It concludes that, in view of what has been said, whilst Williams’ views are applicable and appropriate to many areas of the Stone case, ‘traditional’ moral views on rights, obligations and principles cannot be entirely laid aside in evaluating this.

Pp. 451. 98.00. isbn 3-88405-091-5. his anniversary collection of papers connected with Russell’s 1905 publiTcation of “On Denoting” reflects both the (...) almost mythic status that paper has achieved in analytic philosophy and the quite variegated nature of the significance that philosophers have seen in it. The papers in this collection break down roughly into two sorts. There are those which take a historical approach and attempt to explicate various aspects of the content of the OD article. The other sort might be labelled “application” papers in which Russell’s analysis in OD is seen as a tool or a model for subsequent philosophical work, in the spirit of Ramsey’s much quoted “paradigm of philosophy” remark. The volume opens with a reprint of the OD text with pagination indicated for the original Mind printing, for the text in Collected Papers 4 and for the widely referenced Logic and Knowledge Russell collection edited by R. C. Marsh. The Mind and Papers texts use the American convention of single quotation marks within double quotation marks. The Marsh edition (and the text given here) uses the inverse British convention. Readers need to be aware that paper authors here, and elsewhere, vary in which text they cite. The end of the volume has a comprehensive 21-page bibliography of the secondary literature. In between there are thirteen papers. I will be rather brief with the “application” papers, since I believe that Russell readers will tend to favour the more historically oriented papers. Some of the application papers wander quite far afield from Russell’s treatment of definite descriptions. For instance the paper by Thomas Mormann on “Description, Construction and Representation from Russell and Carnap to Stone” takes off from Russell’s assertion that his theory of descriptions was an early version of his subsequent interest in substituting “constructions” for “inferred entities” such as space-time points. The paper is almost exclusively a (worthwhile and mathematically astute) analysis of Russell’s efforts along these lines in Our russell: the Journal of Bertrand Russell Studies n.s. 26 (winter 2006–07): 167–90 The Bertrand Russell Research Centre, McMaster U. issn 0036-01631 _Russell_ journal (home office): E:CPBRRUSSJOURTYPE2602\REVIEWS.262 : 2007-01-24 01:12 168 Reviews Knowledge of the External World and The Analysis of Matter. The author argues that Russell’s constructions did not actually achieve the effects he wanted, but that (curiously) they can be properly developed within the later framework of topological spaces developed by Marshall Stone in 1937. The paper by Guido Imaguire, “Theory of Descriptions and Inferential Semantics”, explicitly eschews an “exegetical” approach and allies itself with a “systematical approach, in which one analyses possible new features and extensions of the proposed theory” (p. 397). The extension considered here is to “inferential semantics”, especially that of Robert Brandom. The spirit of this approach is to take the semantics of a language to be determined by the set of allowed inferences within that language. Imaguire takes as an essential lesson of Russell’s theory of descriptions that definite descriptions and proper names cannot be treated as singular terms of a language in the same manner. He goes on to argue for a criterion for distinguishing proper names from definite descriptions based on inferences allowed between sentences containing them, and he takes this distinction to argue for a modification of Brandom’s treatment of singular terms in his inferential semantics. Elena Tatievskaya’s paper on “Russell’s Theory of Descriptions and Wittgenstein on Internal Properties of Propositions” is another paper that is mainly about something other than Russell and his theory of descriptions. It is a very detailed study of Wittgenstein’s attempt to make good on his claim that the logical symbols of propositional logic notation, such as v and ~, do not correspond to “logical” components of propositions (Tractatus...

This chapter outlines something of Mario Bunge’s long life and career as a physicist-philosopher originally living and working in Argentina for 40 years, then in Canada for nearly 60 years. It indicates the extraordinary breadth, depth and quantity of his research publications. It deals briefly with some key components of his work, such as: systemism, causation, theory analysis, axiomatization, ontology, epistemology, physics, psychology and philosophy of mind, social science, probability and Bayesianism, defence of the Enlightenment project, and education. Finally, the (...) chapter gives an account of the structure of the festschrift, and an indication of each of the 41 contributions. (shrink)

Consideration of the counting and reidentification of particulars leads naturally enough to the orthodox doctrine that, “on pain of indefiniteness,” an identity statement in some way involves or presupposes a general term or “covering concept”: i.e., that the principium individuationis or criterion of identity implied depends upon the kind of thing in question. Thus it is said that an auditor understands the question whether A is the same as B only in so far as he knows, however informally or implicitly, (...) the answer to the supplementary question, “The same what?”.

This chapter begins by noting the importance of debates in science education that hinge upon support for or rejection of the Enlightenment project. It then distinguishes the historic eighteenth-century Enlightenment from its articulation and working out in the Enlightenment project; details Mario Bunge’s and others’ summation of the core principles of the Enlightenment; and fleshes out the educational project of the Enlightenment by reference to the works of John Locke, Joseph Priestley, Ernst Mach, Philipp Frank and Herbert Feigl. It indicates (...) commonalities between the Enlightenment education project and that of the liberal education movement, and for both projects it points to the need to appreciate history and philosophy of science.

This paper critically examines the claim that parallel distributed processing (PDP) networks are autonomous learning systems. A PDP model of a simple distributed associative memory is considered. It is shown that the 'generic' PDP architecture cannot implement the computations required by this memory system without the aid of external control. In other words, the model is not autonomous. Two specific problems are highlighted: (i) simultaneous learning and recall are not permitted to occur as would be required of an autonomous system; (...) (ii) connections between processing units cannot simultaneously represent current and previous network activation as would be required if learning is to occur. Similar problems exist for more sophisticated networks constructed from the generic PDP architecture. We argue that this is because these models are not adequately constrained by the properties of the functional architecture assumed by PDP modelers. It is also argued that without such constraints, PDP researchers cannot claim to have developed an architecture radically different from that proposed by the Classical approach in cognitive science.

We all have moral beliefs. But what if one beleif conflicts with another? DePaul argues that we have to make our beliefs cohere, but that the current coherence methods are seriously flawed. It is not just the arguments that need to be considered in moral enquiry. DePaul asserts that the ability to make sensitive moral judgements is vital to any philosophical inquiry into morality. The inquirer must consider how her life experiences and experiences with literature, film and theatre have influenced (...) her capacity for making moral judgments and attempt to ensure that this capacity is neither naive nor corrupted.

History, Philosophy and Science Teaching argues that science teaching and science teacher education can be improved if teachers know something of the history and philosophy of science and if these topics are included in the science curriculum. The history and philosophy of science have important roles in many of the theoretical issues that science educators need to address: the goals of science education; what constitutes an appropriate science curriculum for all students; how science should be taught in traditional cultures; what (...) integrated science is; how scientific literacy can be promoted; and the conflict which can occur between science curriculum and deep-seated religious or cultural values and knowledge. In part, answers to these questions hinge on views about the nature of science, views that are best informed by historical and philosophical study. Outlining the history of liberal, or contextual, approaches to the teaching of science, Michael Matthews elaborates contemporary curriculum developments that explicitly address questions about the nature and the history of science. He provides examples of classroom teaching and develops useful arguments on constructivism, multicultural science education and teacher education. The book will appeal to school and university science teachers, educators of science teachers, and historians and philosophers of science. (shrink)

The first edition of The Scientific Background to Modern Philosophy took the dialogue of science and philosophy from Aristotle through to Newton. This second edition adds eight chapters, taking the dialogue through the Enlightenment and up to Darwin. This anthology is an attempt to help bridge the gap between the history of science and the history of philosophy.

One merit claimed for john rawls's coherence method, Wide reflective equilibrium, Is that it transcends the traditional two tiered approach to moral inquiry according to which one must choose as one's starting points either particular moral judgments or general moral principles. The two tiered conception of philosophical method is not limited to ethics. The most detailed exposition of the conception can be found in r m chisholm's various discussions of the problem of the criterion. While chisholm's work has played a (...) major role in structuring the way epistemologists think about method, It has not similarly influenced the deliberations of moral theorists. But moral philosophers are not the only ones with myopia, For neither rawls's coherentist method nor classical moral intuitionism figure in chisholm's taxonomy. One aim is to correct the vision of both parties by expanding chisholm's taxonomy in order to make clear how intuitionism and rawls's coherentist method are related to the methods identified by chisholm. My other aim is to argue for coherentism of the sort defended by rawls against the other non-Skeptical methods I consider. (shrink)

One aim philosophers have in constructing moral theories is to identify the natural or non-Moral characteristics that make actions right or obligatory, Things good, Or persons virtuous. Yet we have no clear understanding of what it is for certain of a thing's non-Moral properties to be responsible for its moral properties. Given the recent interest in the concept of supervenience one might think that the dependence of moral on natural properties could be explained in terms of it. Unfortunately, None of (...) the definitions of supervenience offered so far is adequate to this task, And indeed, There is some reason to think that this dependence relation is ultimately mysterious.

In the introduction to his account of the debate concerning religion between Cleanthes, Philo and Demea, Pamphilus remarks that ‘reasonable men may be allowed to differ where no one can reasonably be positive’. Pamphilus goes on to suggest that natural theology is an area that abounds with issues about which ‘no one can reasonably be positive’. Assuming that the beliefs of reasonable men are themselves reasonable, Pamphilus can be interpreted as holding that If no one is reasonably positive that the (...) proposition p is true or that it is false, a man might reasonably believe that p or might reasonably believe that not p.

The past decade has seen a renewed interest in moral psychology. A unique feature of the present endeavor is its unprecedented interdisciplinarity. For the first time, cognitive, social, and developmental psychologists, neuroscientists, experimental philosophers, evolutionary biologists, and anthropologists collaborate to study the same or overlapping phenomena. This review focuses on moral judgments and is written from the perspective of cognitive psychologists interested in theories of the cognitive and affective processes underlying judgments in moral domains. The review will first present and (...) discuss a variety of different theoretical and empirical approaches, including both behavioral and neuroscientific studies. We will then show how these theories can be applied to a selected number of specific research topics that have attracted particular interest in recent years, including the distinction between moral and conventional rules, moral dilemmas, the role of intention, and sacred/protected values. One overarching question we will address throughout the chapter is whether moral cognitions are distinct and special, or whether they can be subsumed under more domain-general mechanisms. (shrink)

This book examines solutions to the crisis of modernity proposed by the Spanish philosopher Miguel de Unamuno and the Mexican philosopher Antonio Caso. Acceptance of the objective claims of modern scientific rationality and the consequent rejection of the objective validity of artistic, moral, and religious claims generates the crisis of modernity. The problem is that of justifying artistic, moral, and religious claims. Miguel de Unamuno in his classic work,The Tragic Sense of Life, addresses the conflict between the belief in personal (...) immortality and modern scientific rationality. Holding that there is no rational justification for the belief in immortality, Unamuno finds a solution in a “saving scepticism” to act “as if” he deserved immortality. In his book Existence as Economy, as Art, and CharityCaso attempts to create an aposteriori metaphysics based on the “current” results of science supplemented by the intuitions of art and morality. In doing so, Caso believes that he has enlarged the scope of the knowable to include objects of art, morality, and religion. Unamuno, by accepting the strict line of demarcation between faith and reason has no other recourse but to turn to decisionism. By turning to intuitionism, Caso believes that he has blurred the line of demarcation. Decisionism and intuitionism, therefore, are worthy of further exploration. (shrink)

PDP networks that use nonmonotonic activation functions often produce hidden unit regularities that permit the internal structure of these networks to be interpreted (Berkeley et al., 1995; McCaughan, 1997; Dawson, 1998). In particular, when the responses of hidden units to a set of patterns are graphed using jittered density plots, these plots organize themselves into a set of discrete stripes or bands. In some cases, each band is associated with a local interpretation. On the basis of these observations, Berkeley (2000) (...) has suggested that these bands are both subsymbolic and symbolic in nature, and has used the analysis of one network to support the claim that there are fewer differences between symbols and subsymbols than one might expect. We suggest below that this conclusion is premature. First, in many cases the local interpretation of each band is difficult to relate to the interpretation of a network's response; a more appropriate relationship only emerges when a band associated with one hidden unit is considered in the context of other bands associated with other hidden units (i.e., interpretations of distributed representations are more useful than interpretations of local representations). Second, the content that a band designates to an external observer (i.e., the interpretation assigned to a band by the researcher) can be quite different from the content that a band designates to the output units of the network itself.. We use two different network simulations – including the one described by Berkeley (2000) – to illustrate these points. We conclude that current evidence involving interpretations of nonmonotonic PDP networks actually illustrates the differences between symbolic and subsymbolic processing. (shrink)

I’m not sure one even needs to think a state of affairs is true for us to take attitudinal pleasure in it. We surely take pleasure in imagining states of affairs. In such a case, we are well aware that the state of affairs that is the object of our enjoyment does not obtain. What is the proper account of the pleasure we take from imagining? I am fairly sure this is not a type of sensory pleasure. Would it make (...) sense to say that what S is attitudinally pleased by is the state of affairs consisting of S’s imagining p rather than p? I don’t think this will do. It seems possible for S to take pleasure in the imagined state of affairs, p, but not in the state of affairs of S’s imagining p. Consider the case of Chastity, who has had a puritanical upbringing. One day Chastity imagines a torrid romantic encounter with one of her co-workers. Quite in spite of herself, Chastity is pleased by the state of affairs which she merely imagines. But her upbringing has left its mark on her, so she feels very guilty about allowing her thoughts to run in such an unwholesome direction. Chastity is pained by the state of affairs consisting in her imagining the encounter. (shrink)

In this book, Rhodes provides a nonevaluative account of coercion. He begins with a thorough discussion of the charge that coercion is an essentially contested concept. He argues that effective communication of regulations pertaining to human conduct requires a basic level of clarity as to the kind of conduct being regulated. Accordingly, he argues that before we prescribe or proscribe conduct, we should describe it. In short, he maintains that wherever possible description should precede prescription and proscription. Rhodes begins his (...) descriptive project by providing a fundamental account of human motivation. Upon this foundation he supports his distinctions between threats, offers, throffers, and neutral proposals. He argues that all coercion claims can be understood in light of these components. He applies this analysis to three prominent accounts of coercion as advanced by F.A. Hayek, Harry Frankfurt, and Robert Nozick. After comparing and contrasting these views, Rhodes provides his own account. Rhodes's account is based upon the identification of what he refers to as perceived-threat-avoidance-behavior as a necessary condition for coercion. As a descriptive, or nonevaluative, account, Rhodes is able to identify coercion independent from normative judgments. He argues that it is not the wrongfulness of some conduct that makes it coercion, instead, it is the coerciveness of some conduct that makes it wrong. Unique to Rhodes's account, coercion is not necessarily wrong. As a descriptive account, his view permits an independent analysis of the moral status of an act of coercion. The book concludes with a discussion of the normatively significant variables of a coercion claim. (shrink)

What aspects and features of events impel people to label them as miraculous? Three studies examined people's miracle conceptions and the factors that lead them to designate an event as a miracle. Study 1 identified the basic elements of laypersons’ miracle beliefs by instructing participants to define a miracle, to list five events that they considered miraculous, and to state what they believed to be the purpose of miracles. Results showed that individuals tend to view miracles as highly improbable and (...) beneficial occurrences that instill hope and faith in people. Studies 2 and 3 investigated people's intuitive miracle theories. Findings demonstrated that people tend to label events as miracles when the events in question were of high magnitude, were obtained in an unusual manner, resulted in a beneficial health outcome, personally affected the participant, involved a person of worthy character, and depicted a low-probability event.
