We study the groups Gal L and Gal KP, and the associated equivalence relations EL and EKP, attached to a first order theory T. An example is given where EL≠ EKP. It is proved that EKP is the composition of EL and the closure of EL. Other examples are given showing this is best possible.

There is a common view in medical ethics that the patient's right to be informed entails, as well, a correlative right not to be informed, i.e., to waive one's right to information. This paper argues, from a consideration of the concept of autonomy as the foundation for rights, that there can be no such ‘right’ to refuse relevant information, and that the claims for such a right are inconsistent with both deontological and utilitarian ethics. Further, the right to be informed (...) is shown to be a mandatory right (though not a welfare right); persons are thus seen to have both a right and a duty to be informed. Finally, the consequences of this view are addressed: since the way in which we conceptualize our problems tends to determine the actions we take to resolve them, it is important properly to conceptualize patients' requests not to be informed. There may be many reasons for acting in accord with such a request, but it is a mistake to conceptualize one's act as ‘respecting a right possessed by persons’.

Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.

To examine the ethical issues involved in governmental decisions with potential health risks, we review the history of the decision to raise the interurban speed limit in Israel in light of its impact on road death and injury. In 1993, the Israeli Ministry of Transportation initiated an “experiment” to raise the interurban speed limit from 90 to 100 kph. The “experiment” did not include a protocol and did not specify cut-off points for early termination in the case of adverse results. (...) After the raise in the speed limit, the death toll on interurban roads rose as a result of a sudden increase in speeds and case fatality rates. The committee's decision is a case study in unfettered human experimentation and public health risks when the setting is non-medical and lacks a defined ethical framework. The case study states the case for extending Helsinki type safeguards to experimentation in non-medical settings. (shrink)

The purpose of this essay is to elucidate certain difficulties in the text of the Eryxias and to make the author's position as a thinker clearer than it has hitherto been. The Eryxias is a work which has suffered severely from excessive partisanship. While German and Dutch scholars of the eighteenth century appear to have valued it highly—a great deal too highly—as a work of enlightened ethical purpose, the scholarship of the nineteenth century was almost unanimous in condemning it as (...) an inept imitation of Plato's early writings. It soon became apparent, however, that it was not a mere imitation. The economist Hagen recognized in it traces of Stoic doctrine and proceeded somewhat hastily to the conclusion that the author was ‘a Stoic … who expressed the sentiments of his school in the form of a Platonic dialogue.’ Otto Schrohl of Göttingen, whose thesis is the most considerable work on the subject, is less emphatic in claiming the author as a Stoic, but nevertheless traces most of his ideas to Stoic and Cynic origins. This view is modified but retained in its essentials by Professor Souilhé in the Budé edition of Plato. While stressing the importance of the Platonic element, he agrees that the author's point of view has been influenced by Stoic and Cynic teaching, the influence of Cynicism being in his opinion predominant.

My presentation will evidently be the longest since I will be presenting the results of two major surveys done in Moscow, Pskov, and a number of other cities and villages in July-September 1990 and in August-October 1991. The interpretation of the findings of these surveys was done by me together with S.B. Filatov, while the actual investigations were carried out by S.B. Filatov, L.G. Byzov, L.M. Vorontsova, and G.L. Gurevich. The purpose of the surveys was above all to shed some (...) light on the picture of contemporary religiosity and on the connection between religious beliefs and political attitudes. What do the findings of these surveys tell us? (shrink)

Background: Since the passage of the Patient Self-Determination Act, numerous policy mandates and institutional measures have been implemented. It is unknown to what extent those measures have affected end-of-life care, particularly with regard to the do-not-resuscitate order.Methods: Retrospective cohort study to assess associations of the frequency and timing of DNR orders with advance directive status, patient demographics, physician’s specialty and extent of documentation of discussion on end-of-life care.Results: DNR orders were more frequent for patients on a medical service than on (...) a surgical service and were made earlier in the hospital stay for medicine than for surgical patients . 22.18% of all patients had some form of an advance directive in their chart, yet this variable had no impact on the frequency or timing of DNR ordering. Documentation of DNR discussion was significantly associated with the frequency of DNR orders and the time from DNR to death .Conclusions: The physician’s specialty continues to have a significant impact on the frequency and timing of DNR orders, while advance directive status still has no measurable impact. Additionally, documentation of end-of-life discussions is significantly associated with varying DNR ordering rates and timing. (shrink)

OBJECTIVES: To analyse the attitudes of medical personnel towards terminally ill patients and their right to be fully informed. DESIGN: Self-administered questionnaire composed of 56 closed questions. SETTING: Three general hospitals and eleven health centres in Granada (Spain). The sample comprised 168 doctors and 207 nurses. RESULTS: A high percentage of medical personnel (24.1%) do not think that informing the terminally ill would help them face their illness with greater serenity. Eighty-four per cent think the patient's own home is the (...) best place to die: 8.9% of the subjects questioned state that the would not like to be informed of an incurable illness. CONCLUSION: In our opinion any information given should depend on the patient's personality, the stage of the illness and family circumstances. Our study confirms that a hospital is not the ideal environment for attending to the needs of the terminally ill and their families. (shrink)

Children, because of age-related reasons, are a vulnerable population, and protecting their health is a social, scientific and emotional priority. The increased susceptibility of children and fetuses to environmental agents has been widely discussed by the scientific community. Children may experience different levels of chemical exposure than adults, and their sensitivity to chemical toxicities may be increased or decreased in comparison with adults. Such considerations also apply to unborn and newborn children. Therefore, research on children is necessary in both clinical (...) and environmental fields, to provide age-specific relevant data regarding the efficacy and safety of medical treatments, and regarding the assessment of risk from unintended environmental exposure. In this context, the stakeholders are many, including children and their parents, physicians and public health researchers, and the society as a whole, with its ethical, regulatory, administrative and political components. The important ethical issues are information of participants and consent to participate. Follow-up and protection of data should be discussed in the context of biobanks, where children obtain individual rights when they become adults. It is important to realise that there are highly variable practices within European countries, which may have, in the past, led to differences in practical aspects of research in children. A number of recommendations are provided for research with children and environmental health. Environmental research with children should be scientifically justified, with sound research questions and valid study protocols of sufficient statistical power, ensuring the autonomy of the child and his/her family at the time of the study and later in life, if data and samples are used for follow-up studies. When children are enrolled, we recommend a consent dyad, including parental informed consent and the child’s assent and/or informed consent from older minors. For evaluation of the studies including children, a paediatrician should always be involved in the research ethics committee. (shrink)
