The authors describe the ethical considerations underlying the inclusion of mental health services into a prioritizedhealth care system. The Oregon Health Plan is a process for defining and delivering basic health services to an entire state. As the plan was developed, the mental health community needed to decide whether or not to participate in the process and, if so, how. Lengthy discussions among mental health consumers, family members, and providers led to a strategy that emphasized the integration of mental health (...) and chemical dependency services into a comprehensive and universal health care program. This approach appears to have achieved relative parity for mental health. (shrink)

This paper contributes to the foundations of a theory of rational choice for artificial agents in dynamic environments. Our work is developed within a theoretical framework, originally due to Bratman, that models resource-bounded agents as operating against the background of some current set of intentions, which helps to frame their subsequent reasoning. In contrast to the standard theory of rational choice, where options are evaluated in isolation, we therefore provide an analysis of situations in which the options presented to an (...) agent are evaluated against a background context provided by the agent’s current plans—commitments to future activities, which may themselves be only partially specified. The interactions between the new options and the background context can complicate the task of evaluating the option, rendering it either more or less desirable in context than it would have been in isolation.  2001 Elsevier Science B.V.

In THE MISSING MOMENT a distinguished molecular biologist explores the nature of time and argues for a radical rethinking of how time affects our sense of self, our mortality, and the future of science and medicine. Only in the past few years have we learned enough about the brain for this remarkable book to be written. We know now that our brains continually filter the present through memories and emotions of the past. In fact, strictly speaking, we live in the (...) past: since it takes the brain a second to process perceptions, what we think is the present actually happened a second ago. We also know where and how the unconscious operates and how painful memories are repressed; repression is not a psychological defect but an evolutionary necessity for our species. All thought, even the most rational, is permeated with unconscious feelings, fears, and emotions. Scientists, like the rest of us, make choices for reasons they don't understand. Thus the direction of scientific research is driven by private demons, not public needs. We can see this in medical science, where doctors develop the tools to diagnose genetic diseases they cannot cure, bringing pain rather than comfort to patients. Today science can do more good than ever before, and it can also do more harm. The time has come for scientists and others to abandon the notion that there is any such thing as the disinterested pursuit of truth. Instead, they must strive for a therapeutic self-awareness of their unconscious agendas and work for larger goals than personal immortality. (shrink)

The Gendered Cyborg brings together material from a variety of disciplines that analyze the relationship between gender and technoscience, and the way that this relationship is represented through ideas, language and visual imagery. The book opens with key feminist articles from the history and philosophy of science. They look at the ways that modern scientific thinking has constructed oppositional dualities such as objectivity/subjectivity, human/machine, nature/science, and male/female, and how these have constrained who can engage in science/technology and how they have (...) limited our ideas of the possibilities for both humanity and science. Later sections contain readings that present key feminist theories about representation to examine how gender and technoscience are represented in areas of particular contemporary interest: the new human reproductive technologies, science fiction, film and the Internet. The readings constantly ask "Is this for women, for human beings?" Contributors: Alison Adam, Anne Balsamo, Lynda K.

There has been much interest in the possibility of connectionist models whose representations can be endowed with compositional structure, and a variety of such models have been proposed. These models typically use distributed representations that arise from the functional composition of constituent parts. Functional composition and decomposition alone, however, yield only an implementation of classical symbolic theories. This paper explores the possibility of moving beyond implementation by exploiting holistic structure-sensitive operations on distributed representations. An experiment is performed using Pollack’s (...) Recursive Auto-Associative Memory. RAAM is used to construct distributed representations of syntactically structured sentences. A feed-forward network is then trained to operate directly on these representations, modeling syn- tactic transformations of the represented sentences. Successful training and generalization is obtained, demonstrating that the implicit structure present in these representations can be used for a kind of structure-sensitive processing unique to the connectionist domain.

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.

What do we mean when we call a work of art "beautiful"? How have artists responded to changing notions of the beautiful? Which works of art have been called beautiful, and why? Fundamental and intriguing questions to artists and art lovers, but ones that are all too often ignored in discussions of art today. Elizabeth Prettejohn argues that we simply cannot afford to ignore these questions. Charting over two hundred years of western art, she illuminates the vital relationship between our (...) changing notions of beauty and specific works of art, from the works of Kauffman to Whistler, Ingres to Rosetti, Cezanne to Pollack. Beautifully illustrated with 100 photographs--60 in full color--Beauty and Art concludes with a challenging question for the future: Why should we care about beauty in the twenty-first century?

This volume presents a colourful and entertaining overview of German intellectual history by a central figure in its development. Heinrich Heine (1797-1856), famous poet, journalist, and political exile, studied with Hegel and was personally acquainted with the leading figures of the most important generation of German writers and philosophers. In his groundbreaking History he discusses the history of religion, philosophy, and literature in Germany up to his time, seen through his own highly opinionated, politically aware, philosophically astute, and always ironic (...) perspective. This work, and other writings focussing especially on Heine's rethinking of Hegel's philosophy, are presented here in a new translation by Howard Pollack-Milgate. The volume also includes an introduction by Terry Pinkard which examines Heine both in relation to Hegel and Nietzsche and as a thinker in his own right. (shrink)

We focus on the production of efficient descriptions of objects, actions and events. We define a type of efficiency, textual economy, that exploits the hearer’s recognition of inferential links to material elsewhere within a sentence. Textual economy leads to efficient descriptions because the material that supports such inferences has been included to satisfy independent communicative goals, and is therefore overloaded in the sense of Pollack [18]. We argue that achieving textual economy imposes strong requirements on the representation and reasoning (...) used in generating sentences. The representation must support the generator’s simultaneous consideration of syntax and semantics. Reasoning must enable the generator to assess quickly and reliably at any stage how the hearer will interpret the current sentence, with its (incomplete) syntax and semantics. We show that these representational and reasoning requirements are met in the SPUD system for sentence planning and realization. (shrink)
