Two types of variables impact face recognition: estimator variables that cannot be controlled and system variables that are under direct control by the criminal justice system. This article addresses some of the reasons that eyewitnesses are prone to making errors, particularly false identifications. It provides a discussion of the differences between typical facial memory and eyewitness studies and shows that the two areas generally find similar results. It reviews estimator variable effects and focuses on system variables. Traditional facial recognition researchers (...) rarely study system variables but reveal important factors that police and policy makers should consider with regard to eyewitness identification and the courts. It concludes that there is still room for considerable improvement in identification procedures and wants to encourage more system variable research as a means of reducing wrongful convictions.

The acceptance or rejection of computer aids to clinical reasoning is determined not only by the preferences and prejudices of potential users, but also by whether the output generated by the computer aid represents sound clinical judgment. This paper deals with the issue of the appropriate criteria for evaluating the clinical ‘reasoning’ of computer aids. Evaluation of a computer aid should include an assessment of the accuracy or appropriateness of its conclusions and an assessment of the scope of its considerations. (...) In order to use a conclusion generated by a computer aid as a basis for clinical action, information must be available on the alternative conclusions that might have been drawn, the degree of confidence in each conclusion, and the consequences that may result from acting upon the wrong conclusion. If this information is not generated as part of the output of a computer aid, it may be obtained through the use of its explanation and display capabilities, if the aid has such capabilities. Explanation and display capabilities permit the examination of the operations of the computer aid. Examination of a computer's operations is also the most feasible means to evaluate the soundness of its ‘reasoning’. (shrink)

Hawthorne and Magidor's criticisms of the model of presupposition and assertion that I have used and defended are all based on a rejection of some transparency or introspection of assumptions about speaker presupposition. This response to those criticisms aims first to clarify, and then to defend, the required transparency assumptions. It is argued, first, that if the assumptions are properly understood, some prima facie problems for them do not apply, second, that rejecting the assumptions has intuitively implausible consequences, and third, (...) that the 'margin of error' argument against the principle of positive introspection has a false premiss. The paper concludes with a response to a criticism of what Hawthorne and Magidor call 'the uniformity principle' that is used in the model to explain some pragmatic phenomena. (shrink)

Description: The book presents a systematic view of the landmark developments in analytic philosophy in the twentieth century. It highlights the development of the concepts such as language, meaning, truth, reference, necessity, analyticity, etc. which have been central to analytic philosophy. The book consists of four parts, namely: Part I The Linguistic Revolution; Part II The Logic of Language; Part III The Primacy of the Semantical and Part IV Language, Mind and Metaphysics. Part I discusses the nature of the linguistic (...) revolution and the analytic method. Part II presents a panoramic view of the fall of formal language philosophy and the rise of the ordinary language philosophy in the west. Part III brings out the semantic issues like the problems of truth, meaning, reference, etc. Part IV attempts to discuss the nature of language-reality relationship, the nature of mental representations and the concept of mind and also the metaphysical issues of realism and anti-realism. Finally, it brings out the metaphysics of freedom, value and reason. The author has attempted to bring out the issues of analytic philosophy in a systematic and coherent fashion. Analytic philosophy, in spite of the appearances to the contrary, is a systematic philosophy with a built-in metaphysics of man and the universe. The book will be of interest to the general students of philosophy as well as the specialists in philosophy working in the areas of philosophy of language and meaning. (shrink)

Although scholars have expended increasing efforts over the last twenty years or so in either detecting or establishing large structural and thematic units within Ovid's perpetuum carmen, little attention, as far as I am aware, has been directed towards the evident care taken by Ovid in his arrangement of material within individual episodes, and the resultant over-all structure of those episodes. The aim of the present paper is to focus attention upon a single episode to which Ovid seems to have (...) paid particular attention in these respects. I refer to the long story of Phaethon, which occupies the last part of book 1, and most of the first half of book 2, of the Metamorphoses, and intend to explore two different lines of approach in examining the structure of this episode.
