In list-method directed forgetting, reexposure to forgotten List 1 items has been shown to reduce directed forgetting. proposed that reexposure to a few List 1 items only during a direct test of memory reinstates the entire List 1 episode. In the present experiments, part-list reexposure in the context of indirect as well as direct memory tests reduced directed forgetting. Directed forgetting was reduced when 50% or more of the items were reexposed, and was intact when only 25% were reexposed. Furthermore, (...) part-list reexposure appeared to reinstate only reexposed items-not the entire List 1 episode. (shrink)

This paper describes an intelligent algorithm for traffic sign recognition which converges quickly, is accurate in its segmentation and adaptive in its behaviour. The proposed approach can segment images of traffic signs in different lighting and environmental conditions and in different countries. It is based on using Kohonen's Self-Organizing Maps as a clustering tool and it is developed for Intelligent Vehicle applications. The current approach does not need any prior training. Instead, a slight portion, which is about 1% of the (...) image under investigation, is used for training. This is a key issue to ensure fast convergence and high adaptability. The current approach was tested by using 442 images which were collected under different environmental conditions and from different countries. The proposed approach shows promising results; good improvement of 73% is observed in faded traffic sign images compared with 53.3% using the traditional algorithm. The adaptability of the system is evident from the segmentation of the traffic sign images from various countries where the result is 96% for the nine countries included in the test. (shrink)

BLWith new text and full apparatus criticusThe Eudemian Ethics was one of two ethical treatises which Aristotle wrote on the subject of ethica or `matters to do with character'. Although the two works cover much the same ground, the Nicomachean Ethics is better known; the poor manuscript tradition of the Eudemian Ethics has made correct translation and interpretation of the text extremely difficult. The subject of the work is the choice of a certain means of conduct, made by a `man (...) of practical wisdom', between two extremes of behaviour: asceticism and yielding to uncontrolled impulses. Aristotle also stresses the notion of moral intention and the importance of virtue of character. This new Oxford Classical Text of the Eudemian Ethics is the result of many years of work. After Sir David Ross's death, his original text was substantially reworked and revised by his friend and colleague R. R. Walzer, who was aided in the revision by his former pupil Mrs Jean Mingay, who continued his work after his death in 1974. Mrs Mingay was fortunate in being able to make use of previously unpublished contributions from D. J. Allan after his death in the late seventies, and more recently has been helped in her work by the suggestions of Professor D. A. Russell, David Robinson, and Christopher Rowe. (shrink)

Current UK legislation is impacting upon the feasibility and cost-effectiveness of medical record-based research aimed at benefiting the NHS and the public heath. Whereas previous commentators have focused on the Data Protection Act 1998, the Health and Social Care Act 2001 is the key legislation for public health researchers wishing to access medical records without written consent. The Act requires researchers to apply to the Patient Information Advisory Group for permission to access medical records without written permission. We present a (...) case study of the work required to obtain the necessary permissions from PIAG in order to conduct a large scale public health research project. In our experience it took eight months to receive permission to access basic identifying information on individuals registered at general practices, and a decision on whether we could access clinical information in medical records without consent took 18 months. Such delays pose near insurmountable difficulties to grant funded research, and in our case £560 000 of public and charitable money was spent on research staff while a large part of their work was prohibited until the third year of a three year grant. We conclude by arguing that many of the current problems could be avoided by returning PIAG’s responsibilities to research ethics committees, and by allowing “opt-out” consent for many public health research projects.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Plato and Aristotle in Agreement? Platonists on Aristotle from Antiochus to PorphyryR. M. DancyGeorge E. Karamanolis. Plato and Aristotle in Agreement? Platonists on Aristotle from Antiochus to Porphyry. Oxford: Clarendon Press, 2006. Pp. x + 419. Cloth, $125.00.Coleridge wrote: “Every man is born an Aristotelian or a Platonist. I do not think it possible that anyone born an Aristotelian can become a Platonist; and I am sure that (...) no born Platonist can ever change into an Aristotelian. They are two classes of man, beside which it is next to impossible to conceive a third.”Ancient Platonists could not be counted on to accept this kind of dichotomy, and that is what Karamanolis’s book is about. (It may be usefully compared with Lloyd P. Gerson’s 2005 book, Aristotle and Other Platonists.) It covers Antiochus (second century BC), Plutarch [End Page 634] of Chaeronea, Numenius, Atticus, Ammonius Saccas, Plotinus, and Porphyry (third century AD). And it does so with incredible thoroughness, making it a tough read. The book began as a dissertation; it still has something of the air of one.The longest chapter is devoted to Porphyry, whom Karamanolis claims to be the first Platonist to write commentaries on books of Aristotle, and the first to adopt the view that Aristotle simply was in agreement with Plato—the founder of a tradition in scholarship to the effect that “Plato is named as the authority in metaphysics, and Aristotle in logic” (330). His concluding paragraph is this:It is this understanding of philosophizing which lies behind the formation of the Pla-tonist syllabus I described in the beginning of this book. This remains the situation until the Renaissance. When Renaissance humanists revive ancient philosophy, especially Platonism, as happened in Renaissance Florence, they re-establish this very model. Few other shifts in the history of Western philosophy are of such significance as the one which we, quite rightly, attribute to Porphyry.(330)The “Platonist syllabus” to which Karamanolis here adverts is perhaps summed up when he says that “from the third to the sixth century AD... Aristotle was appropriated by Platonists because they found his philosophy, if properly studied, a prerequisite for, and conducive to, an understanding of Plato’s thought” (4). More precisely, Karamanolis’s book is about Porphyry’s view and the background of its formation.Answering Karamanolis’s title question is not what is at stake; rather, he is concerned with how the Platonists listed above answered it. So we are not getting a history of the reading of Plato and Aristotle as agreeing or disagreeing from the very beginning. The early Academy and the skeptical Academy before Antiochus, for example, do not figure, except incidentally, in Karamanolis’s story (although there is a useful appendix on the early peripatetics). There is enough here to keep us busy without this.Dealing with any of Karamanolis’s Platonists is made more difficult by the nature of the material that remains: except for Plutarch and Plotinus, it is almost entirely fragmentary. So it is a question of interpreting not just the target authors, whose works we do not possess, but the sources we have for them, who have their own hobby-horses to ride, and hence are not always reliable. Karamanolis pays suitable attention to such details. But the back-and-forth discussion required can make it difficult to keep the larger picture in view.Karamanolis’s Platonists do not uniformly go for the agreement of Plato and Aristotle. As Karamanolis has it, Porphyry is the only one to swallow it whole: “... nowhere does Porphyry criticize Aristotle,” he concludes (322). This requires him to explain away what he regards as misunderstandings of the evidence (243–45 records some disagreements, and the Porphyry chapter throughout is dedicated to rebuttal). Karamanolis is at least prima facie convincing. At the opposite end of the spectrum are Atticus and Numenius, whose antipathy toward Aristotle is universal.For the rest, whether we are to say that Plato and Aristotle were in agreement obviously depends on what the agreement is to be about. There is, among Karamanolis’s Platonists, a good deal of interesting variation over that. Most of those who... (shrink)

We argue that thoughts are structures of concepts, and that concepts should be individuated by their origins, rather than in terms of their semantic or epistemic properties. Many features of cognition turn on the vehicles of content, thoughts, rather than on the nature of the contents they express. Originalism makes concepts available to explain, with no threat of circularity, puzzling cases concerning thought. In this paper, we mention Hesperus/Phosphorus puzzles, the Evans-Perry example of the ship seen through different windows, and (...) Mates cases, and we believe that there are many additional applications. (shrink)

I had a strange dream, or half-waking vision, not long ago. I found myself at the top of a mountain in the mist, feeling very pleased with myself, not just for having climbed the mountain, but for having achieved my life's ambition, to find a way of answering moral questions rationally. But as I was preening myself on this achievement, the mist began to clear, and I saw that I was surrounded on the mountain top by the graves of all (...) those other philosophers, great and small, who had had the same ambition, and thought they had achieved it. And I have come to see, reflecting on my dream, that, ever since, the hard-working philosophical worms have been nibbling away at their systems and showing that the achievement was an illusion. True, their skeletons, indigestible to worms, remained, and were surprisingly similar to one another. But I was led to think again about what one can, and what one cannot, achieve in this direction.

Following an introductory classification of prescriptive language that emphasizes the parallel between imperatives and moral language, this chapter distinguishes between the indicative and imperative moods of language. It then dismisses various attempts to account for imperatives, particularly their reduction to indicatives as well as expressivist theories like Ayer's and Stevenson's.

It is my intention in this paper to highlight the dangers which arise when people appeal to moral intuitions to settle questions in political, and in general in applied, philosophy. But first I want to ask why all or nearly all of us are in favour both of liberty and of equality – why all our intuitions are on their side. In the case of liberty it is easy to understand why. Although philosophers have held diverse theories about the concept (...) of liberty – theories which have been drawn together into two main groups in a famous lecture by Sir Isaiah Berlin – there cannot be much doubt that in the mind of the ordinary man to have liberty is to be under no constraint in doing what one wants to do. This, at any rate, is a main constituent of the concept of liberty as all of us understand it. Since, therefore, it seems self-evidently true that we want to be able to do what we want, we are bound to want liberty and, in general, to be in favour of it. We want it for ourselves; if we universalize our prescriptions, this constrains us to be in favour of it for others as well. That explains why, if any politician can claim that he is fighting for liberty, he is likely to win a large following. In the case of equality the matter is not so clear cut. (shrink)
