This paper summarizes three lines of research that are motivated by the practical problem of helping users find information from external data sources, most notably computers. The application areas include information retrieval, text categorization, and question answering. A common theme in these applications is that practical information access problems can be solved by analyzing the statistical properties of words in large volumes of real world texts. The same statistical properties constrain human performance, thus we believe that solutions to practical information (...) access problems can shed light on human knowledge representation and reasoning.

We surveyed 1005 postdoctoral fellows by questionnaire about ethical matters related to biomedical research and publishing; 33% responded. About 18% of respondents said they had taken a course in research ethics, and about 31% said they had had a course that devoted some time to research ethics. A substantial majority stated willingness to grant other investigators, except competitors, access to their data before publication and to share research materials. Respondents’ opinions about contributions justifying authorship of research papers were mainly consistent (...) but at variance with those of many biomedical journal editors. More than half said they had observed what they considered unethical research practices. To increase the chances of getting a grant funded, 27% said they were willing to select or omit data to improve their results; to make publication of their work more likely or to benefit their career, 15% would select or omit data and 32% would list an undeserving author. Of respondents who thought they had been unfairly denied authorship on a paper, or been listed with or asked to list an undeserving author, 75% said they would be willing to list an undeserving author (P<0.001). Having taken a course dealing with research ethics had no effect on stated willingness to select or omit data or to fabricate data in the future, but was positively associated with willingness to grant undeserved authorship (P<0.04). Although these results do not controvert research demonstrating the effectiveness of ethics courses during professional education, they indicate that the research environment is a powerful component of a trainee’s experience and ethical development.

Initially proposed as rivals of classical logic, alternative logics have become increasingly important in areas such as computer science and artificial intelligence. Fuzzy logic, in particular, has motivated major technological developments in recent years. Susan Haack's Deviant Logic provided the first extended examination of the philosophical consequences of alternative logics. In this new volume, Haack includes the complete text of Deviant Logic , as well as five additional papers that expand and update it. Two of these essays critique fuzzy (...) logic, while three augment Deviant Logic 's treatment of deduction and logical truth. Haack also provides an extensive new foreword, brief introductions to the new essays, and an updated bibliography of recent work in these areas. Deviant Logic, Fuzzy Logic will be indispensable to students of philosophy, philosophy of science, linguistics, mathematics, and computer science, and will also prove invaluable to experienced scholars working in these fields.

[opening paragraph]: Do you believe, deep down, that you exist? Do you feel as though `you' make the decisions and run `your' life? Above all do you think that `you' are conscious? If so, according to Guy Claxton's latest book, you have got it all wrong.

In many toxic-tort cases - notably in Oxendine v. Merrell Dow Pharmaceuticals, Inc, and in Joiner v. G.E., - plaintiffs argue that the expert testimony they wish to present, though no part of it is sufficient by itself to establish causation "by a preponderance of the evidence," is jointly sufficient to meet this standard of proof; and defendants sometimes argue in response that it is a mistake to imagine that a collection of pieces of weak evidence can be any stronger (...) than its individual components. This article draws on the epistemological theory I first presented in 1993 in Evidence and Inquiry, and then amplified and refined in 2003 in Defending Science - Within Reason. This theory of evidence shows that, under certain conditions, a combination of pieces of evidence none of which is sufficient by itself really can warrant a casual conclusion to a higher degree than any of its components alone. When my account is applied to the very complex congeries of evidence typically proffered to prove general causation in these toxic-tort cases, it improves on the influential "Bradford Hill criteria" for assessing causation; and it suggests answers to questions frequently raised in such cases: e.g., whether epidemiological evidence is essential for proof of causation, and whether such evidence should be excluded if it is not statistically significant. Moreover, the argument of this paper reveals that by obliging courts to screen each item of expert testimony individually for reliability, the atomism implicit in Daubert will sometimes stand in the way of an accurate assessment of the worth of complex causation evidence.

Transhumanists would have humanity's creation of posthumanity be our governing aim. Susan B. Levin challenges their overarching commitments regarding the mind, brain, ethics, liberal democracy, knowledge, and reality. Her critique unmasks their notion of humanity's self-transcendence via science and technology as pure, albeit seductive, fantasy.

Peer review and publication is one of the factors proposed in Daubert v. Merrell Dow Pharmaceuticals, Inc. as indicia of the reliability of scientific testimony. This Article traces the origins of the peer-review system, the process by which it became standard at scientific and medical journals, and the many roles it now plays. Additionally, the Author articulates the epistemological rationale for pre-publication peer-review and the inherent limitations of the system as a scientific quality-control mechanism. The Article explores recent changes in (...) science, in scientific publishing, and in the academy that have put the system under strain. The Author argues that Justice Blackmun's advice to courts - that peer-reviewed publication is relevant, but is not dispositive - is of little practical help. Instead, the Author suggests questions that courts should ask in assessing the significance of the fact that testimony is, or is not, based on peer-reviewed publication and illustrates with reference to another Bendectin case, Blum v. Merrell Dow Pharmaceuticals, Inc., where some of these questions were asked. (shrink)

This study examined self-recognition processing in both the auditory and visual modalities by determining how comparable hearing a recording of one’s own voice was to seeing photograph of one’s own face. We also investigated whether the simultaneous presentation of auditory and visual self-stimuli would either facilitate or inhibit self-identification. Ninety-one participants completed reaction-time tasks of self-recognition when presented with their own faces, own voices, and combinations of the two. Reaction time and errors made when responding with both the right and (...) left hand were recorded to determine if there were lateralization effects on these tasks. Our findings showed that visual self-recognition for facial photographs appears to be superior to auditory self-recognition for voice recordings. Furthermore, a combined presentation of one’s own face and voice appeared to inhibit rather than facilitate self-recognition and there was a left-hand advantage for reaction time on the combined-presentation tasks.

The Macmillan Company New York, led by the Bretts, was a major player in American life. But it had a secret: the company was majority owned by the London parent. As the US came to eclipse the UK, the arrangement led to growing tensions. Finally, in 1951, London was persuaded to sell its stake. But the UK firm found itself unable to use the family name for a new American venture, sparking a legal fight that lasted until 2002. This account (...) of an important event in publishing history adds new detail from archival sources, supporting a fresh reading and correcting earlier errors. It also brings into view a significant amount of material that is published for the first time. The article argues that, although there were hard business reasons for the sale, cultural and personal factors were also consequential and these two types of agency, rational and emotional, work in interrelated ways.
