Feldman and Levin present a model for movement control in which the system is said to seek equilibrium points, active movement being produced by shifting frames of reference in space. It is argued that whatever merit this model might have is limited to an understanding of “the how” and not “the why” we move. In this way the authors seem to be forced into a dualistic position leaving the upper level of the proposed control hierarchy “floating.”.

We examine data on and models of small world properties and parameters of social networks. Our focus, on tie-strength, multilevel networks and searchability in strong-tie social networks, allows us to extend some of the questions and findings of recent research and the fit of small world models to sociological and anthropological data on human communities. We offer a 'navigability of strong ties' hypothesis about network topologies tested with data from kinship systems, but potentially applicable to corporate cultures and business networks.

Physicians are expected to engage patients as partners in identifying the possible benefits and harms associated with treatment options and selecting from among medically appropriate treatment options, rather than simply dictating what treatments patients will and will not receive. This collaborative model reflects the recognition that citizens in multicultural societies have diverse values and are likely to have different views about whether the possible benefits of a medical intervention outweigh the possible harms. However, there are circumstances in which the collaborative (...) process breaks down due to irresolvable disagreement. Especially challenging are cases in which patients are expected to die if they do not receive a treatment and either the patients or their surrogates insist on the treatment despite the physician's belief that providing it is ill advised. The source of disagreement is often differing appraisals of the risks and potential benefits. In such cases, physicians generally judge that there is insufficient likelihood or magnitude of benefit to justify the burdens or expense of treatment, while patients or surrogates believe that the small chance of preventing the patient's death is sufficient to justify the costs and potential burdens to the patient.There is a perception that surgeons enjoy considerable discretion in deciding when the risks of a procedure outweigh the expected benefits. An important contrast can be drawn between surgeons and intensivists—physicians who specialize in the medical management of critically ill patients. We will argue that there are good reasons for subjecting the decisions of both surgeons and intensivists to some oversight. We begin by showing that, for many cases, major professional society guidelines for intensivists recommend oversight via a procedural mechanism rather than unilateral decision‐making by individual clinicians. Next, we present reasons for adopting a procedural approach to dispute resolution, and we argue that these reasons apply to situations in which intensivists believe that patients or surrogates are requesting inappropriate life support as well as to many disagreements between surgeons and surrogates. Finally, we present and respond to several objections. (shrink)

We construct a class of relations on computable structures whose degree spectra form natural classes of degrees. Given any computable ordinal and reducibility r stronger than or equal to m-reducibility, we show how to construct a structure with an intrinsically invariant relation whose degree spectrum consists of all nontrivial r-degrees. We extend this construction to show that can be replaced by either or.

Mr. T. H. Mcpherson has given, in a recent article in PHILOSOPHY , various reasons for supposing that there was a development in Butler's ethics from the Sermons to the Analogy . He argues that Butler was in the Sermons a “rational egoist” or “Ethical Eudaemonist,” and in the Analogy an Intuitionist. By “Ethical Eudaemonism” he seems1 to mean that “the ground or criterion of rightness is conduciveness to the agent's interest” or that “it is the happiness-producing character of acts (...) that makes them right” . I shall use the phrase “McPherson's view” to denote the theory that this was Butler's view in the Sermons. (shrink)

I believe that Moore's appeal to common sense has been misunder-stood both by his defenders and his critics. Besides the mistakes of the latter, there is one enormous howler which, in my opinion, the former have committed. This is to confuse or coalesce two quite distinct appeals which he made, namely the appeal to common sense and the appeal to ordinary language.

The paternalism, autonomy debate was influenced by traditional ideas that reasons are either objective (based on values existing independent of any particular person) or subjective (based on values tied to individual's personal histories). This dichotomy has been rewarding for the health care community. However, the tenets of this debate have influenced the nature of deliberation in a way that seriously compromises the ability of health care professionals and patients to bring reflection (the search for justified reasons) to a successful end. (...) It sets up the moral landscape not as one of unity and reciprocity, but as one of divisiveness and distance-where one person (the physician) does something to another (paternalism) or for another (patient autonomy), rather than with another. This distance and divisiveness undermines the unity of wills and genuine reciprocity that I argue is indispensable for genuinely good relationships and necessary for successfully establishing what reasons there are to act. It has created an abyss in communication that even recent suggestions for change cannot bridge. In this paper, I discuss the nature of this abyss and the problems it has created by demonstrating that traditional theoretical ideas about the nature of reasons have influenced the nature of deliberation in health care. I argue that recent suggestions for “justified paternalism” fail to bridge the abyss. Finally, I suggest that to be successful, we must change the framework; we must reject the ideas of objective and subjective value and embrace instead the idea that values are intersubjective.

Despite the readily available discussion on counseling supervision models for over a quarter of a century, there is little attention in the literature with respect to how developmental supervision models align with existential philosophy. One model, The Integrated Developmental Model (IDM), is a robust and well-accepted model of supervision with embedded undertones of existentialism requiring scholarly discussion. The primary goal of this article is to emphasize the parallels between the IDM and Sartre’s philosophical principles of existentialism thereby creating a meaning (...) making framework for supervisors to enhance developmental growth of their supervisees.

Gray takes an information-processing paradigm as his departure point, invoking a comparator as part of the system. He concludes that consciousness is to be found “in” the comparator but is unable to point to how the comparison takes place. Thus, the comparator turns out not to be an entity arising out of brain research per se, but out of the logic of the paradigm. In this way, Gray both reinvents dualism and remains trapped in the language game of his own (...) model – ending up dealing with the unknowable. (shrink)

In many research studies, tumor biopsies are an unavoidable requirement for achieving key scientific aims. Yet some commentators view mandatory research biopsies as coercive and suggest they should be optional, or at least optional until further data are obtained regarding their scientific usefulness. Further complicating the ethical picture is the fact that some research biopsies offer a potential for clinical benefit to trial participants. We interviewed and surveyed a convenience sample of participants in phase I clinical trials at a single (...) institution. Our primary aim was to describe phase I participants’ understanding of whether a research biopsy offered them the prospect of medical benefit. We also endeavored to describe participants’ views about biopsies—specifically, the benefits of biopsies, if any, and whether biopsies were acceptable, risky, or discouraged trial participation. Finally, we collected data on demographics and attitudes to see if any strong correlations with misunderstanding, acceptability, or riskiness existed. Overall, the respondents tended to view research biopsies as acceptable, though they did not succeed in identifying the lack of benefit of a research biopsy. These findings call for renewed efforts in consent conversations and documents to carefully describe the benefits, or lack thereof, of research biopsies. (shrink)
