Nunez's description of the brain as a medium capable of wave propagation has provided some fundamental insights into its dynamics. This approach soon reaches the descriptive limits of the brain as a physical system, however. We point out some biological constraints which differentiate the brain from physical systems and we elaborate on its consequences for future research.

Increasingly, national governments across the globe are prioritizing investments in neuroscience. Currently, seven active or in-development national-level brain research initiatives exist, spanning four continents. Engaging with the underlying values and ethical concerns that drive brain research across cultural and continental divides is critical to future research. Culture influences what kinds of science are supported and where science can be conducted through ethical frameworks and evaluations of risk. Neuroscientists and philosophers alike have found themselves together encountering perennial questions; these questions are (...) engaged by the field of neuroethics, related to the nature of understanding the self and identity, the existence and meaning of free will, defining the role of reason in human behavior, and more. With this Perspective article, we aim to prioritize and advance to the foreground a list of neuroethics questions for neuroscientists operating in the context of these international brain initiatives.

Background and objectives Conscientious refusal of abortion has been discussed widely by medical ethicists but little information on practitioners' opinions exists. The American College of Obstetricians and Gynecologists (ACOG) issued recommendations about conscientious refusal. We used a vignette experiment to examine obstetrician-gynecologists' (OB/GYN) support for the recommendations. Design A national survey of OB/GYN physicians contained a vignette experiment in which an OB/GYN doctor refused a requested elective abortion. The vignette varied two issues recently addressed by the ACOG ethics committee—whether the (...) doctor referred and whether the doctor disclosed their objection to the abortion. Participants and setting 1800 OB/GYN randomly selected physicians were asked to complete a mail survey containing the vignette. The response rate was 66% (n=1154) after excluding 40 ineligible cases. Measurement Physicians indicated their approval for the vignette doctor's decision. Main results Overall, 43% of OB/GYN physicians responded that the conscientious refusal exercised by the vignette physician was appropriate. 70% rated the vignette doctor as acting appropriately when a referral was made. This dropped to 51% when the doctor disclosed objections to the patient, and to 12% when the doctor disclosed objections and refused to make a referral. Consistent with previous research, males were more likely to support disclosure and refusal to refer. Highly religious physicians supported non-referral but not disclosure. Conclusion OB/GYN physicians are less likely to support conscientious refusal of abortion if physicians disclose their objections to patients. This is at odds with ACOG recommendations and with some models of the doctor–patient relationship. (shrink)

A longitudinal, epidemiological study was carried out in a rural area of Kenya with a population of about 28,000 between 1974 and 1980. Population registration during this time showed that population growth was very high between 1974 and 1978 (4·4% per year) and much lower in 1979 and 1980 (1·1%). Natural increase was nearly as high as in Kenya as a whole (3·7%) in this period. Fertility was somewhat lower than in all Kenya (the crude birth rate was 46 per (...) 1000) while mortality was substantially lower (7 per 1000). Evidence is presented supporting the argument that these low mortality rates are genuine. Levels of temporary and permanent migration are high and probably characteristic for many parts of Kenya. The change in population growth in 1979 and 1980 is probably due to changes in economic conditions leading in particular to less in-migration and to more out-migration. (shrink)

Harris’ reply to our defence of the National Institute for Clinical Excellence’s (NICE) current cost-effectiveness procedures contains two further errors. First, he wrongly draws a conclusion from the fact that NICE does not and cannot evaluate all possible uses of healthcare resources at any one time and generally cannot know which National Health Service (NHS) activities would be displaced or which groups of patients would have to forgo health benefits: the inference is that no estimate is or can be made (...) by NICE of the benefits to be forgone. This is a non-sequitur. Second, he asserts that it is a flaw at the heart of the use of quality-adjusted life years (QALYs) as an outcome measure that comparisons between people need to be made. Such comparisons do indeed have to be made, but this is not a consequence of the choice of any particular outcome measure, be it the QALY or anything else. (shrink)

Two particular forms of absolute space-time theories are examined. There follows a derivation of their predictions for measurements that are within present-day detection limits.

Apart from the names of Jan Baudouin de Courtenay (1845-1929), Mikołaj Kruszewski (1851-1887), and, later, Jerzy Kuryłowicz (1895-1978), Polish linguists and Polish linguistics generally have been little known in the West. The first two were mentioned with approval by Saussure in an unpublished paper, and this reference was picked up by Roman Jakobson and others many years later. Kuryłowicz, for his part, made himself well known in the West through his important work as Indo-Europeanist, even Semiticist, and as a general (...) linguist. The present volume is a first attempt to broaden the perspectives on the Polish contribution to linguistics both inside and outside of Poland during the past centuries. Specialists in their respective fields contributed chapters on the origins and development of general linguistics (Z. Wąsik), applied linguistics (F. Grucza), lexicology (T. Piotrowski), dialectology (St. Gogolewski), and onomastics (S. Gala), followed by five chapters presenting the theories of the arguably most remarkable Polish linguistic thinkers, from Baudouin de Courtenay (A. Adamska-Sałaciak), Kruszewski (F. M. Berezin), and Kuryłowicz (W. Smoczyński) to Mikołaj Rudnicki (1881-1978) and Ludwik Zabrocki (1907-1977) (both written by J. Bańczerowski). Detailed individual bibliographies, a full index of names (with life dates of Polish linguists from the Renaissance to the present day), and a thorough index of subjects and terms make this volume an important reference tool for anyone wishing to acquaint himself with the rich heritage of Polish linguistic thought.

In this article the perspective shifts to the “upstream” end of the agricultural knowledge and information system (AKIS). Because knowledge policy and strategic decision-making are not the prerogative of the public sector, organizations such as cooperative unions and multinational companies are included. After considering the influence of the changing environment on the nature of the AKIS, the role of knowledge management and policy in the emerging knowledge and information market is examined. Special attention is given to public and private R&D. (...) The article then looks where information technology (IT) fits in and what considerations determine strategic investment in IT projects and sustained services. Some of the European experiences with this strategic investment are evaluated. (shrink)

The growth of knowledge and its effects on the practice of medicine have been issues of philosophical and ethical interest for several decades and will remain so for many years to come. The outline of the present volume was conceived nearly three years ago. In 1987, a conference on this theme was held in Maastricht, the Netherlands, on the occasion of the founding of the European Society for Philosophy of Medicine and Health Care (ESPMH). Most of the chapters of this (...) book are derived from papers presented at that meeting, and for the purpose of editing the book Stuart Spicker, Ph. D., joined two founding members of ESPMH, Henk ten Have and Gerrit Kimsma. The three of them successfully brought together a number of interesting contribu tions to the theme, and ESPMH is grateful and proud to have initiated the production of this volume. The Society intends that annual meetings be held in different European countries on a rotating basis and to publish volumes related to these meetings whenever feasible. In 1988, the second conference was held in Aarhus, Denmark on "Values in Medical Decision Making and Resource Allocation in Health Care". In 1989, a meeting was held in Czestochowa, Poland, on "European Traditions in Philosophy of Medicine. From Brentano to Bieganski". It is hoped that these conferences and the books to be derived from them, will initiate a new European tradition, lasting well into the 21 st century! P. J. (shrink)

Experiments designed to test Special Relativity are reviewed and their capabilities of distinguishing Special Relativity from Absolute Space-Time theories is analyzed. Of two specific forms of Absolute theories proposed in recent years, we show that one is refuted by past experiments while the other is still in contention.

The ethical challenges of caring for the chronically ill are of increasing concern to nurses as they attempt to create humanitarian environments for long-term care. This article suggests two ethical perspectives to guide the agenda of the nursing profession to achieve social change in the care of the chronically ill and aging. First, a reemphasis on the public duties of the professions is recommended which extends beyond serving the interests of the nursing profession to recognizing the need to serve the (...) common good. Second, the limitations of the autonomy paradigm are explored and the foundation for the development of a new moral paradigm is analyzed in terms of its' potential usefulness in addressing ethical problems of chronic illness. Several initiatives that nursing must undertake to facilitate the emergence of this paradigm are proposed. (shrink)

A cross-cultural survey experiment revealed a dominant tendency to rely on a rule’s letter over its spirit when deciding which behaviors violate the rule. This tendency varied markedly across (k = 15) countries, owing to variation in the impact of moral appraisals on judgments of rule violation. Compared with laypeople, legal experts were more inclined to disregard their moral evaluations of the acts altogether and consequently exhibited stronger textualist tendencies. Finally, we evaluated a plausible mechanism for the emergence of textualism: (...) in a two-player coordination game, incentives to coordinate in the absence of communication reinforced participants’ adherence to rules’ literal meaning. Together, these studies (total n = 5,794) help clarify the origins and allure of textualism, especially in the law. Within heterogeneous communities in which members diverge in their moral appraisals involving a rule’s purpose, the rule’s literal meaning provides a clear focal point—an identifiable point of agreement enabling coordinated interpretation among citizens, lawmakers, and judges.
