Whereas previous research has focused on the link between workload and task performance, less is known about the intervening mechanisms influencing this relationship. In the present study, we test the moderating roles of daily recovery and total sleep time in the relationship between work pressure and daily task performance. Using performance and recovery theories, we hypothesized that work pressure relates positively to daily task performance, and that both daily recovery in the form of psychological detachment and relaxation, and total sleep (...) time independently enhance this relationship. Our hypotheses were tested in a 30-day diary study with 110 officer cadets on a cross-Atlantic voyage on a Naval sail ship. The results of multilevel modeling lend support to all three hypotheses. Taken together, our findings suggest that recovery and sleep duration between shifts play a key role in the relationship between daily work pressure and task performance. We discuss the implications of these findings for the stressor-detachment model. (shrink)

Jewish and Christian philosophy existed side by side in the Middle Ages. Both sought the same goal: the explanation of God and His universe. Both utilized the same sources; yet each attained different philosophical and theological systems. The Meditation of the Sad Soul illustrates this divergence between Christian and Jewish thought. Furthermore, since it stands midway between Neo-platonic and Aristotelian Judaism, it underlines the development of key philosophical concepts common to both Judaism and Christianity. Abraham Bar Hayya lived in eleventh (...) century Barcelona, an intellectual center for both Jews and Arabs. The major points of his philosophy blend rabbinical, Neo-platonic and Aristotelian ideas, yet maintain a unique independence of their own. For instance, Abraham cut through the rabbinical and Aristotelian proofs of God, demanding instead a primary positive faith in God's existence. Caught up in the theology of light, he rejected the Platonic idea that darkness was merely an absence of light. Rather, darkness had a force equal to light. Most important, darkness and light were opposites, as were good and evil. God created both. Abraham insists that each had an independent existence in the world. Abraham's thought shows a more "rational" strain which appears later in Christian and even Jewish "heresies." Since good and evil exist as positive forces, man can freely choose his path to salvation. Abraham never gets caught in the Augustinian dilemma of will, grace, and predestination. Further examples of Abraham's independent position crop up in his ideas of creation and time. Creation ex nihilo, of course, but creation in time. Time must have a beginning and, consequently, an end. But man does not have to await passively the Messiah's rectification of sin. Man must repent here on earth and actively lead a good life. He cannot repent after death. How influential was Abraham's tract? The editor calls it a "minor classic" yet does not indicate that it formed a basis for later Christian theology. Maimonides knew it and rejected some of its basic tenets. Still, the book is important since it indicates a striking combination of traditional philosophy subjected to a new critical rationalism, an it foreshadows some of the questions raised by deviant Christian and Jewish theologians.--J.

This book is an important attempt to make explicit the moral and political implications and presuppositions of Ludwig Wittgenstein’s Tractatus Logico-Philosophicus. To many readers of Wittgenstein it will come as a surprise that there should be any significant political implications at all, for Wittgenstein’s work more than that of most other philosophers seems to be concerned exclusively with technical philosophical problems. Nevertheless, even before the appearance of Moran’s study, several commentators have suggested that the Tractatus is at least something more (...) than a treatise for philosophers; and Wittgenstein himself, in a letter to Ludwig von Ficker, stated flatly: "The point of the book is an ethical one." Moran, to the reviewer’s knowledge, is the first philosopher to take Wittgenstein’s own appraisal seriously enough to work out systematically the "wisdom" expressed, if muted, by the Tractatus.

Rendell and Whitehead's thorough review dispels notions that culture is an exclusive faculty of humans and higher primates. We applaud the authors, but differ with them regarding the evolution of cetacean culture, which we argue resulted from the availability of abundant but spatially and temporally patchy prey such as schooling fish. We propose two examples of gene-culture coevolution: (1) acoustic abilities and acoustic traditions, and (2) transmission of environmental information and longevity.

Together, Models and Computability and its sister volume Sets and Proofs will provide readers with a comprehensive guide to the current state of mathematical logic. All the authors are leaders in their fields and are drawn from the invited speakers at 'Logic Colloquium '97' (the major international meeting of the Association of Symbolic Logic). It is expected that the breadth and timeliness of these two volumes will prove an invaluable and unique resource for specialists, post-graduate researchers, and the informed and (...) interested nonspecialist.

The US neutrino community gathered at the Workshop on the Intermediate Neutrino Program at Brookhaven National Laboratory February 4-6, 2015 to explore opportunities in neutrino physics over the next five to ten years. Scientists from particle, astroparticle and nuclear physics participated in the workshop. The workshop examined promising opportunities for neutrino physics in the intermediate term, including possible new small to mid-scale experiments, US contributions to large experiments, upgrades to existing experiments, R&D plans and theory. The workshop was organized into (...) two sets of parallel working group sessions, divided by physics topics and technology. Physics working groups covered topics on Sterile Neutrinos, Neutrino Mixing, Neutrino Interactions, Neutrino Properties and Astrophysical Neutrinos. Technology sessions were organized into Theory, Short-Baseline Accelerator Neutrinos, Reactor Neutrinos, Detector R&D and Source, Cyclotron and Meson Decay at Rest sessions.This report summarizes discussion and conclusions from the workshop.

Introduction: The Dutch Euthanasia Act states that euthanasia is not punishable if the attending physician acts in accordance with the statutory due care criteria. These criteria hold that: there should be a voluntary and well-considered request, the patient’s suffering should be unbearable and hopeless, the patient should be informed about their situation, there are no reasonable alternatives, an independent physician should be consulted, and the method should be medically and technically appropriate. This study investigates whether physicians experience problems with these (...) criteria in medical practice.Methods: In 2006, questionnaires were sent to a random, stratified sample of 2100 Dutch physicians . Physicians were asked about problems in their decision-making related to requests for euthanasia or assisted suicide after enforcement of the 2002 Euthanasia Act.Results: Of all physicians who had received a request for euthanasia or assisted suicide , 25% had experienced problems in the decision-making with regard to at least one of the criteria of due care. Physicians who had experienced problems mostly indicated to have had problems related to evaluating whether or not the patient’s suffering was unbearable and hopeless and whether or not the patient’s request was voluntary or well considered .Discussion: Physicians in The Netherlands most frequently reported problems related to aspects in which they have to evaluate the patient’s subjective perspective. However, it can be questioned whether placing emphasis on these subjective aspects is an adequate fulfilment of the duties imposed on physicians, as laid down in the Dutch Euthanasia Act. (shrink)

The aim of this study was to examine to what extent patients remained silent to the health care system after they experienced abusive or wrongful incidents in health care. Female patients visiting a women’s clinic in Sweden (n = 530) answered the Transgressions of Ethical Principles in Health Care Questionnaire (TEP), which was constructed to measure patients’ abusive experiences in the form of staff’s transgressions of ethical principles in health care. Of all the patients, 63.6% had, at some point, experienced (...) staff’s transgressions of ethical principles, and many perceived these events as abusive and wrongful. Of these patients, 70.3% had remained silent to the health care system about at least one transgression. This silence is a loss of essential feedback for the health care system and should not automatically be interpreted as though patients are satisfied. (shrink)

0-categorical o-minimal structures were completely described by Pillay and Steinhorn 565–592), and are essentially built up from copies of the rationals as an ordered set by ‘cutting and copying’. Here we investigate the possible structures which an 0-categorical weakly o-minimal set may carry, and find that there are some rather more interesting examples. We show that even here the possibilities are limited. We subdivide our study into the following principal cases: the structure is 1-indiscernible, in which case all possibilities are (...) classified up to binary structure; the structure is 2-indiscernible, classified up to ternary structure; the structure is 3-indiscernible, in which case we show that it is k-indiscernible for every finite k. We also make some remarks about the possible structures of higher arities which an 0-categorical weakly o-minimal structure may carry. (shrink)

This paper traces the development of parental rights to accept or to refuse treatment for a defective newborn infant in the United Kingdom and in the United States of America; its main purpose is to explore the common trends from which an acceptable policy may be derived. It is probable that the British law on parental decision-making in respect of infants suffering from Down's syndrome is to be found in the civil case of In Re B rather than in the (...) criminal case of R v Arthur. United States court decisions are strongly influenced by constitutional law and reflect the right to personal privacy. The position on each side of the Atlantic seems very similar but this similarity includes a sense of uncertainty as to legal responsibility. There is a case for agreed guidelines and a suggested format is offered for consideration. (shrink)

The rapid development of physics, the result of observations made and ideas introduced within the last few decades, has brought about a change in the whole system of physical concepts. This fact is common knowledge, and has already attracted the attention of philosophers. It is less well known that geometry too has had its crises, and undergone a reconstruction. For centuries, so-called “geometrical intuition” was used as a method of proof. In geometrical demonstrations, certain steps were allowed because they were (...) “self-evident,” because the correctness of the conclusion was “shown by the adjoined diagram,” etc. A crisis occurred in geometry because such intuition proved to be untrustworthy. Many of the propositions regarded as self-evident or based upon the consideration of diagrams turned out to be false. And so Euclidean geometry was reconstructed by methods free from all intuitive elements and strictly logical in nature. Moreover, for more than a century, various other geometries have been devised purely as logical constructions. Since they start with assumptions different from those of Euclid, and lead to conclusions partly in contradiction with his theorems, they are called “non-Euclidean.” Nevertheless, each one of these geometries is a closed system of propositions exempt from contradiction. Recently, some of them have even found application in physics. (shrink)
