There is currently a debate over whether cognitive architecture is classical or connectionist in nature. One finds the following three comparisons between classical architecture and connectionist architecture made in the pro-connectionist literature in this debate: (1) connectionist architecture is neurally plausible and classical architecture is not; (2) connectionist architecture is far better suited to model pattern recognition capacities than is classical architecture; and (3) connectionist architecture is far better suited to model the acquisition of pattern recognition capacities by learning than (...) is classical architecture. If true, (1)–(3) would yield a compelling case against the view that cognitive architecture is classical, and would offer some reason to think that cognitive architecture may be connectionist. We first present the case for (1)–(3) in the very words of connectionist enthusiasts. We then argue that the currently available evidence fails to support any of (1)–(3). (shrink)

One of the central issue of developmental biology concerns the molecular mechanisms whereby a multipotent cell gives rise to distinct differentiated progeny. Differences between specialised cell types reflect variations in their patterns of gene expression. The regulation of transcription initiation is an important control point for gene expression and it is, therefore, not surprising that transcription factors play a pivotal role in mammalian development and differentiation.Haemopoiesis offers a uniquely tractable system for the study of lineage commitment and differentiation. The importance (...) of transcription factor in the normal regulation of haemopoiesis is underlined by the frequency with which transcription factors are targeted by leukaemogenic mutations. Studies of the function and regulation of haemopoietic transcription factors, especially those expressed in lineage‐restricted patterns, should greatly increase our understanding of the molecular control of haemopoiesis. In this review we have focused on insights provided by recent studies of the GATA and SCL proteins. (shrink)

Writing a little over a decade ago of developments in educational philosophy, R. F. Dearden remarked on the dearth of alternative approaches to that of conceptual analysis which predominated, at least in Anglophone cultures, at that time. One possible avenue of enquiry which he identified as conspicuously absent in this respect was the development of a distinctively Catholic approach to problems of educational philosophy, observing that a work of the mid-war years, Maritain's Education at the Crossroads, appeared to be well (...) nigh the only modern effort in this direction. More than a decade on from this, in a climate no longer exclusively dominated by conceptual analysis - indeed, in which there is unprecedented interest in a wealth of different schools, traditions and approaches to philosophy of education - Dearden's remarks about the absence of a distinctively Catholic perspective still apply. In the following essay, therefore, the authors have undertaken, via a critical analysis of Maritain's educational speculations of half a century ago, to try to discern some of the principal issues and considerations which would need to be addressed in the interests of identifying a distinctively Catholic educational philosophy.

We construct a recursive ultrapower F/U such that F/U is a tame 1-model in the sense of [6, §3] and FU is existentially incomplete in the models of II2 arithmetic. This enables us to answer in the negative a question about closure with respect to recursive fibers of certain special semirings Γ of isols termed tame models by Barback. Erik Ellentuck had conjuctured that all such semirings enjoy the closure property in question. Our result is that while many do, some (...) do not. (shrink)

In their provocative 1988 paper, Fodor and Pylyshyn issued a formidable challenge to connectionists, i.e. to provide a non‐classical explanation of the empirical phenomenon of systematicity in cognitive agents. Since the appearance of F&P's challenge, a number of connectionist systems have emerged which prima facie meet this challenge. However, Fodor and McLaughlin (1990) advance an argument, based upon a general principle of nomological necessity, to show that one of these systems (Smolensky's) could not satisfy the Fodor‐Pylyshyn challenge. Yet, if (...) Fodor and McLaughlin's analysis is correct, it is doubtful whether any existing connectionist system would fare better than Smolensky's. In the view of Fodor and McLaughlin, humans and classical architectures display systematicity as a matter of nomological necessity (necessity by virtue of natural law), but connectionist architectures do not. However, I argue that the Fodor‐Pylyshyn‐McLaughlin appeal to nomological necessity is untenable. There is a sense in which neither classical nor connectionist architectures possess nomological (or‘nomic’) necessity. However, the sense in which classical architectures do possess nomic necessity applies equally well to at least some connectionist architectures. Representational constituents can have causal efficacy within both classical and connectionist architectures. (shrink)

In 1988 Fodor and Pylyshyn issued a challenge to the newly-popular connectionism: explain the systematicity of cognition without merely implementing a so-called classical architecture. Since that time quite a number of connectionist models have been put forward, either by their designers or by others, as in some measure demonstrating that the challenge can be met (e.g., Pollack, 1988, 1990; Smolensky, 1990; Chalmers, 1990; Niklasson and Sharkey, 1992; Brousse, 1993). Unfortu- nately, it has generally been unclear whether these models actually do (...) have this implication (see, for instance, the extensive philosophical debate in Smolensky, 1988; Fodor and McLaughlin, 1990; van Gelder, 1990, 1991; McLaughlin, 1993a, 1993b; Clark, 1993). Indeed, we know of no major supporter of classical orthodoxy who has felt compelled, by connectionist models and argu- ments, to concede in print that connectionists have in fact delivered a non-classical explanation of systematicity.

The paper is divided into two parts, each with subsections. In the first part, I shall discuss some matters that have been extensively examined by Kim, namely what the basic types of supervenience are and how they are pairwise logically related; in the course of this discussion, I shall distinguish a weak from a strong notion of global supervenience. In the second part, I shall examine supervenience in a context in which Kim has not: I shall attempt to solve a (...) puzzle that arises when we consider supervenience relations involving vague properties and/or predicates. This is, of course, not a special case of property/predicate super- venience, but the typical one: for virtually all properties/predicates are vague. The two parts of the paper stand independently of each other. Of the discussion in the first part, essentially all that is presupposed in the second is the notion of “world strong supervenience” defined in section 1 of part I. (shrink)

Background:Palliative care is acknowledged as an appropriate approach to support older people in nursing homes. Ethical issues arise from many aspects of palliative care provision in nursing homes; however, they have not been investigated in this context.Aim:To explore the ethical issues associated with palliative care in nursing homes in the United Kingdom.Design:Exploratory, sequential, mixed-methods design.Methods:Semi-structured interviews with 13 registered nurses and 10 healthcare assistants (HCAs) working in 13 nursing homes in the United Kingdom were used to explore ethical issues in (...) palliative care. The ‘Ethical Issues in Palliative Care for Nursing Homes’ instrument was used to measure the frequency and level of distress arising from ethical issues through a cross-sectional survey with 69 registered nurses and 129 healthcare assistants. Data collection occurred between December 2014 and November 2015.Ethical considerations:Ethical approval was granted by Queen’s University’s School of Nursing and Midwifery Research Ethics Committee and governance sought from each nursing home’s manager.Findings:The interviews revealed three themes: ethical issues in practice; relational issues; and organisational issues. No significant differences between registered nurses and healthcare assistants were evident, confirming the patterns emerging from the interviews. Relational issues, primarily issues with residents and families, occurred most frequently and caused greater distress.Conclusion:The shared environment is key in the experience of ethical issues; therefore, multidisciplinary education is needed for ethical decision making in palliative care. Addressing staff knowledge and service organisation may reduce ethical issues locally and provide a benchmark for global change. (shrink)

The question of when and how the basic concepts that characterize modern science arose in Western Europe has long been central to the history of science. This book examines the transition from Renaissance engineering and philosophy of nature to classical mechanics oriented on the central concept of velocity. For this new edition, the authors include a new discussion of the doctrine of proportions, an analysis of the role of traditional statics in the construction of Descartes' impact rules, and go deeper (...) into the debate between Descartes and Hobbes on the explanation of refraction. They also provide significant new material on the early development of Galileo's work on mechanics and the law of fall. (shrink)

This volume illustrates how the methodology of metaphysics can be enriched with the help of cognitive science. Few philosophers nowadays would dispute the relevance of cognitive science to the metaphysics of mind, but this volume mainly concerns the relevance of metaphysics to phenomena that are not themselves mental. The volume is thus a departure from standard analytical metaphysics. Among the issues to which results from cognitive science are brought to bear are the metaphysics of time, of morality, of meaning, of (...) modality, of objects, and of natural kinds, as well as whether God exists. A number of chapters address the enterprise of metaphysics in general. In traditional analytical metaphysics, intuitions play a prominent role in the construction of, and assessment of theories. Cognitive science can be brought to bear on the issue of the reliability of intuitions. Some chapters point out how results from cognitive science can be deployed to debunk certain intuitions, and some point out how results can be deployed to help vindicate certain intuitions. (shrink)

In this paper I want to do the following things. First I want to show that in the part of the Theaetetus where the relationship between knowledge and perception is examined, the concept of knowledge that is in question is very clearly characterized. We are left in no doubt as to what is to count as knowing. Secondly I want to unravel in some detail the case that Socrates puts on Protagoras’ behalf where he draws on what Protagoras actually wrote (...) (151 E-152C); as opposed to what he may have taught secretly to his pupils (152C-160D). Thirdly I wish to argue that if we let the dialogue speak for itself, it is manifest that this case put up on Protagoras’ behalf at 151 E-152C is not overthrown; it is not even shaken. (shrink)

That is, he restricts the use of the word by setting down what he will consider to be the essential characteristics of knowledge, the sufficient and necessary conditions of its being instantiated. An excellent piece of philosophical procedure. (shrink)

Students of philosophy, psychology, sociology, and literature will welcome this collection of original essays on self-deception and related phenomena such as wishful thinking, bad faith, and false consciousness. The book has six sections, each exploring self-deception and related phenomena from a different perspective.

Because anticipated and retrospective regret play important roles in practical deliberation and motivation, better understanding them can illuminate the contours of human agency. However, the possibility of self-ignorance and the fact that we change over time can make regret—especially anticipatory regret—not only a poor predictor of where the agent will be in the future but also an unreliable indicator of where the agent stands. Granting these, this paper examines the way in which prospective and, particularly, retrospective regret can nevertheless yield (...) important insight into the sorts of creatures we are, both generally and individually. The experience of retrospective regret can show a person she values something in a way she did not know or that she is (or was) a different person than she had thought, insights which can factor into forward-looking, or prospective, deliberation. Such instances of revelatory regret reveal something to the agent about herself as agent. I examine two cases of agential self-ignorance. In the first, the experience of regret reveals what the agent values, not only to others but even to the agent himself. In the second, the agent anticipates experiencing regret for an action but does not experience the regret, suggesting that the agent did not value the rejected alternative in the way she thought. Anticipatory regret is forward-looking and can play an important role in practical deliberation. But insofar as anticipatory regret flows from one’s imperfect judgment and prospection about oneself, retrospective regret can be an important corrective in helping the agent understand her own standpoint.

In his newly updated version of The Anatomy of a Constitutional Law Case, Alan F. Westin provides a documentary portrait of historically important constitutional law case, 'Youngstown Sheet & Tube Co. v. Sawyer, ' from its rise in a bargaining dispute in the steel industry during 1952 to the aftermath of its decision by the United States Supreme Court. Westin has added to his classic book additional materials and personal commentaries collected since the work was first published. The new information (...) covers what went on within the Truman administration, what went on within the Supreme Court when analyzing and resolving issues that come before it. Westin includes selections from transcripts, briefs and other official proceedings, adds notes describing each phase of the constitutional process, and a section of commentary and questions relating this case to others.

Many working women will experience sexual harassment at some point in their careers. While some report this harassment, many leave their jobs to escape the harassing environment. This mixed-methods study examines whether sexual harassment and subsequent career disruption affect women’s careers. Using in-depth interviews and longitudinal survey data from the Youth Development Study, we examine the effect of sexual harassment for women in the early career. We find that sexual harassment increases financial stress, largely by precipitating job change, and can (...) significantly alter women’s career attainment. (shrink)
