We report the results of a randomized trial to assess the impact of an innovative ethics curriculum on the knowledge and confidence of 85 medical house officers in a university hospital programme, as well as their responses to a simulated clinical case. Twenty-five per cent of the house officers received a lecture series, 25 per cent received lectures and case conferences, with an ethicist in attendance, and 50 per cent served as controls. A post-intervention questionnaire was administered. Knowledge scores did (...) not differ among the groups. Confidence regarding ethical issues was significantly greater in the aggregate intervention group compared to the control group. Confidence regarding procedural issues related to ethics was significantly higher for the EI group than for the controls. Responses to a simulated case showed that significantly fewer house officers in the EI group would intubate a patient for whom such therapy would be futile. We conclude that ethics education can have an impact on house officers' confidence and their responses to a simulated case, and that the EI was more effective than the LI. Such results have implications regarding the implementation of ethics education during residency. (shrink)

Notions of purity, perfection, or immaculateness have powered our imagination over the ages. Various images of perfection have held sway in their hallowed times, providing secure streams for channelling human energy. Unfortunately, with the unfolding of the human drama on the world stage, all the images of perfection have suffered damage, epoch on epoch. Different responses have emerged to attempt a restoration. Revival of some of the old images is one such response. Production of new images to serve as worthwhile (...) anchors of value and meaning is another common response. For reasons possibly known only to philosophers and historians, the enterprise called modern science has got thickly embroiled in this civilisational process--first, as the culprit behind the decline of some of the established images, then as the producer of new images, and now, perhaps, as a constant reminder of the perpetual lack of purity and immaculateness in all things human.

In 1885, during initial discussions of J. C. Maxwell's celebrated thermodynamic demon, Whiting (1) observed that the demon-like velocity selection of molecules can occur in a gravitationally bound gas. Recently, a gravitational Maxwell demon has been proposed which makes use of this observation [D. P. Sheehan, J. Glick, and J. D. Means, Found. Phys. 30, 1227 (2000)]. Here we report on numerical simulations that detail its microscopic phase space structure. Results verify the previously hypothesized mechanism of its paradoxical behavior. This (...) system appears to be the only example of a fully classical mechanical Maxwell demon that has not been resolved in favor of the second law of thermodynamics. (shrink)

A laboratory-testable, solid-state Maxwell demon is proposed that utilizes the electric field energy of an open-gap p-n junction. Numerical results from a commercial semiconductor device simulator (Silvaco International–Atlas) verify primary results from a 1-D analytic model. Present day fabrication techniques appear adequate for laboratory tests of principle.

This study represents an improvement in the ethics scales inventory published in a 1988 Journal of Business Ethics article. The article presents the distillation and validation process whereby the original 33 item inventory was reduced to eight items. These eight items comprise the following ethical dimensions: a moral equity dimension, a relativism dimension, and a contractualism dimension. The multidimensional ethics scale demonstrates significant predictive ability.

Purpose: Physicians are often reluctant to discuss “Do Not Resuscitate” orders with patients. Although perceived self-efficacy is a known prerequisite for behavioural change, little is understood about the confidence of physicians regarding DNR discussions.Subjects and methods: A survey of 217 internal medicine attendings and 132 housestaff at two teaching hospitals about their attitudes and confidence regarding DNR discussions.Results: Participants were significantly less confident about their ability to discuss DNR orders than to discuss consent for medical procedures , and this was (...) true for both attendings and housestaff . In a multivariate logistic model of confidence regarding DNR discussions, women were less confident than men ; house officers were less confident than attendings , those who were less confident of their ability to discuss medical procedures were less confident discussing DNR , and those who found talking to patients about DNR orders very difficult reported less confidence than those who did not .Conclusion: We conclude that physicians’ confidence regarding DNR discussions is low compared with their confidence regarding other medical discussions and that confidence varies by sex and perceived difficulty of the task. Efforts to improve DNR discussions should explore the need to tailor educational interventions to fit these characteristics. (shrink)

Twelve essays from a symposium concerned with the influence of relativistic concepts on the development of the social sciences. There is general agreement that methodological relativism, though often appropriate to scientific inquiry, has lead to a normative relativism which is inappropriate to the study of man.--R. D. P.

A journal, many of whose articles bring Thomistic philosophy to bear on non-Thomistic traditions, philosophical and otherwise, in a scholarly and sympathetic fashion.--R. D. P.

A text covering twenty-nine ethical systems from Plato to Stevenson. Each essay treats one thinker and is liberally seeded with quotations from his major works. Thinkers are grouped according to schools of thought.--R. D. P.

A collection of papers delivered at a colloquium in 1960. Most are quite brief; all are at a rather high level of technical sophistication. Of general interest are L. Apostel's "Toward the Formal Study of Models in the Non-Formal Sciences," which concludes that a unique definition of models in terms of their function should be the basis for a general description of this "multiform concept"; H. Freudenthal's discussion of "models in Applied Probability"; a historical treatment of "Model and Insight" by (...) A. Kuipers; and P. Suppes's "Comparison of the Meaning and Uses of Models in Mathematics and the Empirical Sciences," which stresses the "set-theoretical" notion of model and emphasizes the possibility of greater formalization of the empirical sciences through the former. Among other authors represented are E. W. Beth, J. L. Destouches, and J. B. Ubbink.--R. D. P. (shrink)

The general topic is morality, divided into three notions, Action, Wisdom and Grace. The lectures are lively historical reflections on these notions seen in the context of Greek thought, especially that of Plato and Aristotle.--R. D. P.

The focus of this study was to analyze the content, distribution, and comparative genome relationships of 996 chromosome bin-mapped expressed sequence tags accounting for 2266 restriction fragments on the homoeologous group 3 chromosomes of hexaploid wheat. Of these loci, 634, 884, and 748 were mapped on chromosomes 3A, 3B, and 3D, respectively. The individual chromosome bin maps revealed bins with a high density of mapped ESTs in the distal region and bins of low density in the proximal region of the (...) chromosome arms, with the exception of 3DS and 3DL. These distributions were more localized on the higher-resolution group 3 consensus map with intermediate regions of high-mapped-EST density on both chromosome arms. Gene ontology classification of mapped ESTs was not significantly different for homoeologous group 3 chromosomes compared to the other groups. A combined analysis of the individual bin maps using 537 of the mapped ESTs revealed rearrangements between the group 3 chromosomes. Approximately 232 of the consensus mapped ESTs matched sequences on rice chromosome 1 and revealed large- and small-scale differences in gene order. Of the group 3 mapped EST unigenes ∼21 and 32% matched the Arabidopsis coding regions and proteins, respectively, but no chromosome-level gene order conservation was detected. (shrink)
