Gelfond and Lifschitz proposed the notion of a stable model of a logic program. We establish that the set of all stable models in a Herbrand universe of a recursive logic program is, up to recursive renaming, the set of all infinite paths of a recursive, countably branching tree, and conversely. As a consequence, the problem, given a recursive logic program, of determining whether it has at least one stable model, is Σ11-complete. Due to the equivalences established in the (...) authors' previous nonmonotone rule systems papers ), this applies equally to truth maintenance systems and default logics. (shrink)

"_Minding Women _embraces a generation of scholarship, culminating in major new work by leading scholars who are reconfiguring feminist research. This important collection will again change the way we think about race, history, education, and the lives of girls." —_Sally Schwager_, Director Women's History Institute, Harvard University Research on women and girls has exploded during the past twenty years. Since 1977, when the _Harvard Educational Review_ published Carol Gilligan's now-classic article "In a Different Voice," in which she argued so persuasively (...) that women and girls must be understood on their own terms, researchers have been discovering, uncovering, and recovering women's ways of knowing, being, thinking, teaching, and learning. _Minding Women_ charts the wealth of thought and writing related to women and girls and education that this process of discovery has produced. _Minding Women_ begins with a "Classics" section—articles that call attention to the lack of research on girls and women and describe the effect this has had on knowledge and society. The contributors then discuss feminist pedagogy, and how it has changed and been refined over time. Girls and young women are the focus of the next section. Too often their voices and viewpoints are excluded from these discussions, so some of their own writings are included here. The book then explores women's educational history, showcasing some of the rich work in this area over the past twenty years. Identity issues are addressed in the final section, acknowledging that substantial differences exist among groups of women and girls on how they experience the world and their roles, prospects, and lives.

At least since the seminal work of the (US) National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research in the 1970s, a fundamental distinction between research and practice has underwritten both conceptual work in research ethics and regulations governing research involving human subjects. Notwithstanding its undoubted historical importance, I believe the distinction is problematic because it misrepresents clinical inquiry. In this essay, I aim to clarify the character of clinical inquiry by identifying crucial contextual constraints on (...) justification constitutive of clinical science. This analysis shows that, from an epistemological point of view, clinical research and clinical practice are not sharply distinct but intimately intertwined. This result is important in its own right—an enriched understanding of the epistemology of clinical research is valuable in and of itself. But this result is also important because it has profound implications for the ethics of human subjects research. (shrink)

In The Face of Emotions, which was Carroll Izard’s first major attempt at elaborating his differential emotions theory, he stated that the book “presents a theoretical framework for the study of emotions and their role in personality and interpersonal processes.” Yet, over the years, his contribution to personality theory has generally been overshadowed by the attention focused on his views on facial expressions and the structure of emotions. This article will begin with a brief overview of the DET perspective on (...) personality development. Then, it will examine how the DET framework can be used to organize recent findings from three lines of research on adult personality. It will conclude with suggestions for future research as well as some personal recollections. (shrink)

Much of the progress in the fields constituting cognitive science has been based upon the use of explicit information processing models, almost exclusively patterned after conventional serial computers. An extension of these ideas to massively parallel, connectionist models appears to offer a number of advantages. After a preliminary discussion, this paper introduces a general connectionist model and considers how it might be used in cognitive science. Among the issues addressed are: stability and noise‐sensitivity, distributed decision‐making, time and sequence problems, and (...) the representation of complex concepts. (shrink)

Introduction: In The Netherlands, physicians have to be convinced that the patient suffers unbearably and hopelessly before granting a request for euthanasia. The extent to which general practitioners (GPs), consulted physicians and members of the euthanasia review committees judge this criterion similarly was evaluated. Methods: 300 GPs, 150 consultants and 27 members of review committees were sent a questionnaire with patient descriptions. Besides a “standard case” of a patient with physical suffering and limited life expectancy, the descriptions included cases in (...) which the request was mainly rooted in psychosocial or existential suffering, such as fear of future suffering or dependency. For each case, respondents were asked whether they recognised the case from their own practice and whether they considered the suffering to be unbearable. Results: The cases were recognisable for almost all respondents. For the “standard case” nearly all respondents were convinced that the patient suffered unbearably. For the other cases, GPs thought the suffering was unbearable less often (2–49%) than consultants (25–79%) and members of the euthanasia review committees (24–88%). In each group, the suffering of patients with early dementia and patients who were “tired of living” was least often considered to be unbearable. Conclusions: When non-physical aspects of suffering are central in a euthanasia request, there is variance between and within GPs, consultants and members of the euthanasia committees in their judgement of the patient’s suffering. Possible explanations could be differences in their roles in the decision-making process, differences in experience with evaluating a euthanasia request, or differences in views regarding the permissibility of euthanasia.
