To describe the content of practice guidelines on euthanasia and assisted suicide (EAS) and to compare differences between settings and guidelines developed before or after enactment of the euthanasia law in 2002 by means of a content analysis. Most guidelines stated that the attending physician is responsible for the decision to grant or refuse an EAS request. Due care criteria were described in the majority of guidelines, but aspects relevant for assessing these criteria were not always described. Half of the (...) guidelines described the role of the nurse in the performance of euthanasia. Compared with hospital guidelines, nursing home guidelines were more often stricter than the law in excluding patients with dementia (30% vs 4%) and incompetent patients (25% vs 4%). As from 2002, the guidelines were less strict in categorically excluding patients groups (32% vs 64%) and in particular incompetent patients (10% vs 29%). Healthcare institutions should accurately state the boundaries of the law, also when they prefer to set stricter boundaries for their own institution. Only then can guidelines provide adequate support for physicians and nurses in the difficult EAS decision-making process. (shrink)

The author states that his purpose in this work is not primarily Peirce scholarship but epistemology. But the concentration is on Peirce’s theory of knowledge, a concentration which centers around what the author thinks is Peirce’s most valuable contribution to the subject—a solution to the problem of skepticism. In contrast to Descartes’ assertion that knowledge must be based on primitive intuitions, Peirce contends that all thought is in process, an organically intertwined system of inferences, a continuous flow of signs. Because (...) thinking is a process in time, it is always fallible. Rather than this being a hindrance to knowledge, Davis sees this as the key to Peirce’s escape from skepticism, for the knowledge so described is a continuous self-corrective process, a web which, if we but make the effort to untangle it, will continue to reward us with advance toward the truth. Of more revolutionary importance to the theory of knowledge, according to Davis, is Peirce’s theory of abduction, his answer to the problem of how synthetic knowledge is possible. Abduction is the act of making up explanatory hypotheses. It issues in insights which are the outgrowth of creativity and imagination. The test of these unifying ideas is their appropriateness or ability to satisfy our sensibilities. It is instinct, or that to which we are naturally bent, which guides the abductive process. Throughout this book great emphasis is placed on the importance of this to Peirce and to an adequate epistemology of instinct, feelings, the work of the heart, or sensibility. The scientist, as Davis sees it, is thus akin in method to the creative artist. While Davis intends also to show how this aspect of Peirce is consistent with his pragmatic maxim, their relationship is never quite clarified in this work. Nevertheless, the book is a well-written and very readable treatment of Peirce’s epistemology. It also includes a great many comparisons with similar and contrasting positions as found in a wide range of contemporary and classical philosophical treatises.—B.A.M. (shrink)

This book is a collection of 18 essays portraying a "humanistic" outlook on several contemporary moral problems, and includes such essayists as Kurt Baier, Carl Rogers, B. F. Skinner, Sidney Hook, Abraham Edel, John Somerville, and Corliss Lamont. Although each was requested first to give his own definition of humanism and then to work out one application of it from his particular field or interest, these directions are not always strictly adhered to. Half of the essays had in fact, already (...) been published in some form in The Humanist. The 5 topical headings of the book show the diversity of fields and interests portrayed: Ethics, Religion and the Meaning of Life; The Good Life; The Individual: Law, Morality and Social Organization; Justice and Society; and Death. Although the essays are of unequal philosophical depth and acumen, this variety may be appealing for some uses of this as a text. However, two of the essays in particular stand out for this reviewer: "Ethics Without Religion" by Kai Nielsen, which perceptively outlines the problematic for as well as against an ethics not rooted in religion, and "The Enforcement of Morals" by Ernest Nagel which aptly analyzes the problem of the relation between the spheres of morality and law taking as a focus the noted Hart-Devlin debate of this issue. The thread which Kurtz believes unites all of these essays is their portrayal of a humanistic viewpoint, a viewpoint which he attempts to summarize in his own 14-page introduction, "What is Humanism?" But defining humanism is not an easy task. One must steer between a strictly negative view which defines it only in relation to what it opposes, and a broader but rather indefinite view of it as some form of man-centered philosophy. Although Kurtz wants to be positive in his own definition, he seems unable to move away from a negative and rhetorical presentation in which theism is simply stated to be incompatible with humanism. Moreover, his outline of a humanistic ethics is somewhat superficial. For example, he seems unaware of the problems involved in holding that ethical values are man’s own "creation" and at the same time are normative and objective. Nevertheless, the book may be of some help as a supplementary text to stimulate undergraduate students in discussion and study of the topics treated therein.—B.A.M. (shrink)

The author demonstrates that W. E. Hocking’s political philosophy deserves far more consideration than it has so far received not only for its being a study in political philosophy, something there is too little of in the American tradition, but also because of the importance of the problems which are the focus of the study, the problems of liberty and community. Thigpen organizes material from a wide range of sources in Hocking’s extensive bibliography into an orderly presentation that moves from (...) relevant matter in Hocking’s theory of man and of knowledge, through practical applications of this matter to such issues as the basis and purpose of a state, and problems of rights and freedom, to the questions of international relations and world peace.

The historical development of the famous Einstein formula \ is briefly discussed. In this paper, on the basis of the Einstein viewpoint a new general approach is proposed for demonstrating the correctness of the formula \ . It is can be seen that the generalized approach leads to Einstein’s famous formula, too. During recent years, various papers have been published concerning the incompleteness of this famous formula. It is demonstrated that the presented claims in these articles are not mathematically legitimate. (...) It is clear that there are still some important misunderstandings concerning the interpretation of Einstein’s mass-energy equivalence formula. (shrink)

The editor of this book has put together here a very manageable selection from the published articles of C. S. Peirce and has prefaced it with his own very fine 42-page introduction. Being published articles, these have the advantages of being those which Peirce himself thought to be complete. Moreover, they are also thus able to be arranged chronologically and topically. This Moore does by including articles which fall into four major groups: 1) On epistemology, from The Journal of Speculative (...) Philosophy, 1868; 2) On Peirce’s early pragmatism and on the nature of scientific inquiry, from Popular Science Monthly, 1873-1878; 3) On Peirce’s basic metaphysics, from The Monist, 1891-1893; and 4) On his later pragmatism, from The Monist, 1905-1906. In his introduction, the editor summarizes and interrelates some of the key questions in Peirce’s philosophy and in these writings—questions on the nature of potentiality, the validity of the process of scientific inquiry, and the problem of the definition of concepts. Much of this treatment revolves around Peirce’s grappling with the key problem of the nature of universals. In the medieval dispute between the extreme realists and the nominalists, Peirce takes a middle moderate realist position, "that the referent of a concept is to be found in the experience of a specific object". On either of the other views, scientific knowledge would be impossible. (shrink)

Both syntactic and semantic solutions are given for the entailment problem of duality theory. The test algebra theorem provides both a syntactic solution to the entailment problem in terms of primitive positive formulae and a new derivation of the corresponding result in clone theory, viz. the syntactic description of $\operatorname{Inv(Pol}(R))$ for a given set R of finitary relations on a finite set. The semantic solution to the entailment problem follows from the syntactic one, or can be given in the form (...) of an algorithm. It shows, in the special case of a purely relational type, that duality-theoretic entailment is describable in terms of five constructs, namely trivial relations, intersection, repetition removal, product, and retractive projection. All except the last are concrete, in the sense that they are described by a quantifier-free formula. It is proved that if the finite algebra $\underline{M}$ generates a congruence-distributive variety and all subalgebras of $\underline{M}$ are subdirectly irreducible, then concrete constructs suffice to describe entailment. The concept of entailment appropriate to strong dualities is also introduced, and described in terms of coordinate projections, restriction of domains, and composition of partial functions. (shrink)

Guido de Ruggiero (1888-1948) was perhaps the greatest Italian intellectual historian in the twentieth century. He was a fierce champion of liberalism, an ardent opponent of Fascism, an insightful critic and interpreter of his contemporaries, and a formidable philosopher in his own right. Idealism & Experience: The Philosophy of Guido de Ruggiero comprises eight new critical essays, as well as English translations of five of de Ruggiero's most important shorter writings, which chart the development of his thought between 1914 and (...) 1946. Taken together, these essays reveal the range, richness and philosophical sophistication of de Ruggiero's ideas, enabling Anglophone readers to appreciate their enduring relevance in our own troubled times.

Recent results have shown that the relative activation of muscles is different for isometric contractions and for movements. These results exclude an explanation of muscle activation patterns by a combination ofreciprocal and coactivation commands. These results also indicate that joint stiffness is not uniquely determined and that it may be different for isometric contractions and movements.

Simple Heuristics That Make Us Smart invites readers to embark on a new journey into a land of rationality that differs from the familiar territory of cognitive science and economics. Traditional views of rationality tend to see decision makers as possessing superhuman powers of reason, limitless knowledge, and all of eternity in which to ponder choices. To understand decisions in the real world, we need a different, more psychologically plausible notion of rationality, and this book provides it. It is about (...) fast and frugal heuristics--simple rules for making decisions when time is pressing and deep thought an unaffordable luxury. These heuristics can enable both living organisms and artificial systems to make smart choices, classifications, and predictions by employing bounded rationality. But when and how can such fast and frugal heuristics work? Can judgments based simply on one good reason be as accurate as those based on many reasons? Could less knowledge even lead to systematically better predictions than more knowledge? Simple Heuristics explores these questions, developing computational models of heuristics and testing them through experiments and analyses. It shows how fast and frugal heuristics can produce adaptive decisions in situations as varied as choosing a mate, dividing resources among offspring, predicting high school drop out rates, and playing the stock market. As an interdisciplinary work that is both useful and engaging, this book will appeal to a wide audience. It is ideal for researchers in cognitive psychology, evolutionary psychology, and cognitive science, as well as in economics and artificial intelligence. It will also inspire anyone interested in simply making good decisions. (shrink)

A nonlinear two-variable reaction-diffusion model of bone mineral metabolism, built from an overall self-oscillatory compartmental model of calcium metabolism in vivo, has been studied for its ability to generate spatial and spatio-temporal self-organizations in a two-dimensional space. Analytical and numerical results confirm the theoretical properties previously described for this kind of model. In particular, it is shown that, for a given set of reactional parameter values and certain values of the ratio of the two diffusion coefficients, there exists a set (...) of unstable wavenumbers leading spontaneously to the development, from the homogeneous steady state, of either different types of stationary spatial patterns (hexagonal, striped and re-entrant hexagonal patterns) or more or less complex spatio-temporal expressions. We discuss the relevance of analogies established between some spatial or spatio-temporal structures predicted by the model and some peculiar features of the primary bone trabecular architecture which appear during embryonic ossification.

This paper describes the perspectives of stakeholders within the North American dairy industry on key issues affecting the welfare of dairy cattle. Five heterogeneous focus groups were held during a dairy cattle welfare meeting in Guelph, Canada in October 2012. Each group contained between 7 and 10 participants and consisted of a mix of dairy producers, veterinarians, academics, students, and dairy industry specialists. The 1-h facilitated discussions were audio-recorded and transcribed verbatim. Content analysis of the resulting transcripts showed that participants (...) across all stakeholder categories identified lameness as the most important welfare issue facing dairy cattle. Other prominent issues of concern included cow comfort, disease, on-farm mortality, stockmanship, painful procedures, injuries, cull cow management, calf management, and restriction of behavioural freedoms. Participants typically gave several reasons for why they considered issues problematic. Underlying reasons were grouped according to animal-centered concerns [at both the individual and at the herd level ] and industry-centered concerns . This analysis identified areas of shared concern among diverse stakeholder groups, which should aid in the development of standards and policies that satisfy stakeholders within and external to the dairy industry.

Background: Older, frail patients with multimorbidity are at an especially high risk for disease severity and death from COVID-19. The social restrictions proved challenging for the residents, their relatives, and the care staff. While these restrictions clearly impacted daily life in Norwegian nursing homes, knowledge about how the pandemic influenced nursing practice is sparse. Aim: The aim of the study was to illuminate ethical difficult situations experienced by Norwegian nurses working in nursing homes during the COVID-19 pandemic. Research design and (...) participants: The research design involved semistructured individual interviews conducted with 15 nurses working in 8 nursing homes in 3 health regions in Norway, within both urban and rural areas. Ethical considerations: Oral and written information about the study was provided before the participants gave their written consent. The transcribed interviews were de-identified. The study was approved by the Norwegian Centre for Research Data. Findings: Four ethical difficult situations were identified: (a) turning the nursing home into a prison; (b) using medication to maintain peace and order; (c) being left alone with the responsibility; and (d) s. impact on decision-making. Conclusions: The nurses’ ethical challenges were intertwined with external factors, such as national and local guidelines, and the nurses’ own internalized factors, which were connected to their subjective professionality. This duality inflicted emotional distress and gave nurses few opportunities to perform nursing in a professionally sound and safe manner. (shrink)
