A simple model for the description of atomic and ionic species with spectra exhibiting a quantum defect is solved using the Lie algebra su(1, 1). The quantum defect of bound states is related to the phase shift of scattering states. The resonances are discussed in terms of the nonunitary representations of this algebra.

The central issues of regnum versus sacerdotium have been obscured by a concentration on personalities and a murder in a cathedral. Cantor is also concerned with personalities, but in this thorough study of church-state relations in Anglo-Norman England, he goes behind the legend and ably demonstrates that the controversies which were dramatized in blood in 1170 had already been settled by politico-ecclesiastical negotiations more than half-a-century earlier. The main interest of the study is in Cantor's discussion of St. Anselm as (...) an aging ecclesiastical statesman trying to avoid the extremes of that "fanatical high Gregorian" Paschal II, while insisting on the ending of lay investiture despite Henry I's opposition.--H.

© 2016 Regents of the University of California.The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 3,062 new measurements from 721 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. All the particle properties and search limits are listed in Summary Tables. We also give numerous (...) tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, Probability and Statistics. Among the 117 reviews are many that are new or heavily revised, including those on Pentaquarks and Inflation. The complete Review is published online in a journal and on the website of the Particle Data Group. The printed PDG Book contains the Summary Tables and all review articles but no longer includes the detailed tables from the Particle Listings. A Booklet with the Summary Tables and abbreviated versions of some of the review articles is also available. (shrink)

Objective: To evaluate one ethics rounds model by describing nurses’ and doctors’ experiences of the rounds. Methods: Philosopher-ethicist-led interprofessional team ethics rounds concerning dialysis patient care problems were applied at three Swedish hospitals. The philosophers were instructed to promote mutual understanding and stimulate ethical reflection, without giving any recommendations or solutions. Interviews with seven doctors and 11 nurses were conducted regarding their experiences from the rounds, which were then analysed using content analysis. Findings: The goal of the rounds was partly (...) fulfilled. Participants described both positive and negative experiences. Good rounds included stimulation to broadened thinking, a sense of connecting, strengthened confidence to act, insight into moral responsibility and emotional relief. Negative experiences were associated with a sense of unconcern and alienation, as well as frustration with the lack of solutions and a sense of resignation that change is not possible. The findings suggest that the ethics rounds above all met the need of a forum for crossing over professional boundaries. The philosophers seemed to play an important role in structuring and stimulating reasoned arguments. The nurses’ expectation that solutions to the ethical problems would be sought despite explicit instructions to the contrary was conspicuous. Conclusion: When assisting healthcare professionals to learn a way through ethical problems in patient care, a balance should be found between ethical analyses, conflict resolution and problem solving. A model based on the findings is presented. (shrink)

Objective: To evaluate whether ethics rounds stimulated ethical reflection. Methods: Philosopher-ethicist-led interprofessional team ethics rounds concerning dialysis patient care problems were applied at three Swedish hospitals. The philosophers were instructed to stimulate ethical reflection and promote mutual understanding between professions but not to offer solutions. Questionnaires directly before and after rounds were answered by 194 respondents. The analyses were primarily content analysis with Boyd’s framework but were also statistical in nature. Findings: Seventy-six per cent of the respondents reported a moderate (...) to high rating regarding new insights on ethical problem identification, but the ethics rounds did not seem to stimulate the ethical reflection that the respondents had expected (p<0.001). Dominant new insights did not seem to fit into traditional normative ethics but were instead interpreted as hermeneutic ethics. This was illustrated in the extended perspective on the patient and increased awareness of relations to other professions. Regarding insights into how to solve ethical problems, the request for further interprofessional dialogue dominated both before and after rounds. Conclusion: The findings show the need for interprofessional reflective ethical practice but a balance between ethical reflection and problem solving is suggested if known patients are discussed. Further research is needed to explore the most effective leadership for reflective ethical practice. (shrink)

• Aggregates of previously isolated cells of Hydra are capable, under suitable solvant conditions, of regeneration forming complete animals. In a first stage, ecto- and endodermal cells sort out, producing the bilayered hollow structure characteristic of Hydra tissue; thereafter, heads are formed (even if the original cell preparation contained no head cells), eventually leading to the separation of normal animals with head, body column and foot. Hydra appears to be the highest type of organism that allows for regeneration of the (...) entire structure from random cell aggregates. The system is particularly useful for studying cell interactions, tissue polarity, pattern formation, and cell differentiation. (shrink)

Purpose: Josef Mitterer's essays are considered to be important philosophical advancements of radical constructivism. The main purposes of this paper are, on the one hand, to structure the RC landscape and, on the other hand, to investigate the relations of Mitterer's work to radical constructivism in particular and to philosophy in general. Findings: In this short essay focusing on Mitterer's Das Jenseits der Philosophie, I would like to stress two major points. First, Mitterer's book should be considered as one of (...) several contemporary variants of a radical critique of the semantic turn in the philosophy of science that has taken place since the mid-thirties with the works of Rudolf Carnap, Carl G. Hempel, Hilary Putnam, Alfred Tarski and others. Second, it is by no means clear how to determine the relevance of the new semantic critique for the present and future cognitive status of radical constructivism. The degree of relevance depends crucially on the use of the term "radical constructivism." If radical constructivism, as I will argue, is seen as an umbrella term for a group of empirical research programs, then, by sheer necessity, the relevance can be marginal only. If, however, radical constructivism is viewed as a special form of philosophy of language and/or as a new epistemology, then the importance of Josef Mitterer's approach must be judged within the context of available functional alternatives. Implications: An immediate consequence of this article lies in a renewed emphasis on advancing an empirical research agenda for radical constructivism and in an effective downsizing of radical constructivism as a philosophical perspective.

A critical review of gravitational wave theory is made. It is pointed out that the usual linear approach to the gravitational wave theory is neither conceptually consistent nor mathematically justified. Relying upon that analysis it is argued that—analogously to a Yang-Mills propagating field, which must be nonlinear to carry its gauge charge—a gravitational wave must necessarily be nonlinear to transport its own charge—that is, energy-momentum.

This book focuses on issues in epistemology, semantics and logic with Quine’s views always setting the themes, even if Quine does not always remain quite at center stage. Gochet, Professor at Liège and Secretary to the Editorial Board of Logique et Analyse is a prominent of Quine’s views in Europe. The author does not aim to take up the whole of Quine’s philosophy here. Rather, the aim is to “focus on a few central themes...and to treat them thoroughly.” Continental Europe (...) not only recognizes Quine’s importance, then, but it is prepared to talk back: a point which has become increasingly evident in the wake of several recent works on Quine by W.K. Essler (1975), J. Largeault (1980) and Henri Lauener (1982). Gochet has made an earlier contribution to this in the form of his Quine en Perspective (1978) and its German translation (1984). But the present volume is not a further translation of the earlier work. Rather, the author “tried to avoid overlap.”. (shrink)
