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)
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 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)
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 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)
The nature of quantum computation is discussed. It is argued that, in terms of the amount of information manipulated in a given time, quantum and classical computation are equally efficient. Quantum superposition does not permit quantum computers to ''perform many computations simultaneously'' except in a highly qualified and to some extent misleading sense. Quantum computation is therefore not well described by interpretations of quantum mechanics which invoke the concept of vast numbers of parallel universes. Rather, entanglement makes available types of (...) computation processes which, while not exponentially larger than classical ones, are unavailable to classical systems. The essence of quantum computation is that it uses entanglement to generate and manipulate a physical representation of the correlations between logical entities, without the need to completely represent the logical entities themselves.

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.

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)
We review some of the essential novel ideas introduced by Bohm through the implicate order and indicate how they can be given mathematical expression in terms of an algebra. We also show how some of the features that are needed in the implicate order were anticipated in the work of Grassmann, Hamilton, and Clifford. By developing these ideas further we are able to show how the spinor itself, when viewed as a geometric object within a geometric algebra, can be given (...) a meaning which transcends the notion of the usual metric geometry in the sense that it must be regarded as an element of a broader and more general pregeometry.

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)
