In scientific explanations, the explanans theory is sometimes incommensurable with the explanandum empirical data. How is this possible, especially when the explanation is deductive in nature? This paper attempts to solve the puzzle without relying on any particular theory of reference. For us, it is rather obvious that the geometric idea of projection plays a key role in Keplers explanation of Tycho Brahes empirical data. We discover that a similar mechanism operates in theoretic explanations in general. In short, all theoretic (...) explanations are projective explanations. If so, there should be no logical reason why explanans theories cannot be incommensurable with explanandum data. For illustration, we analyse Einsteins explanation of the results of the Michelson–Morley experiment in some detail. (shrink)

This paper starts with an intuitive notion of representational spaces, which is intended to provide an improved version of Kuhn's concept of paradigms. It then proceeds to study the following topics in terms of this new notion: incommensurability, paradigm change, explanation of anomalies, explanation of regularities, explanation of irregularities, and physical necessity. In the course of the investigation, "representational space" gets clarified and defined. It is envisaged that this new concept should throw light on many issues in the philosophy of (...) science.

Objectives: To quantify the use of do-not-resuscitate orders in a tertiary-care children’s hospital and to characterise the circumstances in which such orders are written.Design: Retrospective study conducted in a 500-bed children’s hospital in Taiwan.Patients: The course of 101 patients who died between January 2002 and December 2005 was reviewed. The following data were collected: age at death, gender, disease and its status, place of death and survival. There were 59 males and 42 females with a median age of 103 months (...) . 50 children had leukaemias, and 51 had malignancies other than leukaemia. The t test and the χ2 test were applied as appropriate.Results: The study found that 44% of patient deaths occurred in the paediatric oncology ward; 29% of patient deaths occurred in the intensive care unit; and 28% of patients died in their home or at another hospital. Other findings included the following: 46 of 101 patients died after attempted cardiopulmonary resuscitation and 55 died with a DNR order in effect. The mean age at death was 9.8 years in both groups with or without DNR orders.Conclusions: From the study of patient deaths in this tertiary-care children’s hospital, it was concluded that an explicit DNR order is now the rule rather than the exception, with more DNR orders being written for patients who have been ill longer, who have solid tumours, who are not in remission and who are in the ward.

All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

The fundamental tenet of contemporary sociobiology, namely the assumption of a single process of evolution involving the selection of genes, is critically examined. An alternative multiple-level, multiple-process model of evolution is presented which posits that the primary process that operates via selection upon the genes cannot account for certain kinds of biological phenomena, especially complex, learned, social behaviours. The primary process has evolved subsidiary evolutionary levels and processes that act to bridge the gap between genes and these complex behaviours. The (...) subsidiary levels are development, individual animal learning, and socioculture itself. It is argued that individual learning is pivotal to the derivation and biological analysis of culture. The differences between cultural and noncultural societies are stressed. It is concluded that such a multiple-level model of evolution can form the basis for reconciling opposing sides in the sociobiology debate. (shrink)

We consider extensions of Peano arithmetic suitable for doing some of nonstandard analysis, in which there is a predicate N(x) for an elementary initial segment, along with axiom schemes approximating ω 1 -saturation. We prove that such systems have the same proof-theoretic strength as their natural analogues in second order arithmetic. We close by presenting an even stronger extension of Peano arithmetic, which is equivalent to ZF for arithmetic statements.

This paper starts with an overview of C.G. Jung’s notion of archetypes. His ideas imply that Jungian archetypes can be viewed as the most general examples of the shared awarenesses that occur in groups of people of all sizes, ranging from families to humanity as a whole. The term ‘archetype’ is used in connection with such shared awarenesses in the subsequent discussion. The distinction that Jung made between archetypal representations and archetypes themselves is retained and emphasized. It is then pointed (...) out that archetypal representations are sets of Dawkins’ memes appearing in awareness. Pursuing the line of thought suggested by this, it is further proposed that the meme set can be regarded as analogous to the genotype in biology, while the representation itself resembles the phenotype in heuristically useful respects. Archetypes, as opposed to their representations, are the factors which predispose particular sets of memes to spread within a group of people and enter their awarenesses. It follows from the biological analogy that archetypes can be thought of as regularities that occur in an ‘ecology’ of representations. Because memes are subject to pseudo-Darwinian influences, parallels between the behaviour of representations and the phenomena of parasitology and epidemiology will sometimes be observed. The view of archetypes arrived at opens up a possibility that they might be responsible for some mass behaviours; e.g. those involved in the production of social movements such as Nazism or certain medical conditions of obscure aetiology. Archetypal representations possess in some circumstances the power to fill the consciousnesses of individuals ‘infected’ by them for long periods of time. These points are illustrated in a brief account of fatigue syndromes. Finally, should consciousness have a quantum theoretical basis, details of the epidemiology of archetypal representations will differ from those to be expected if it has no such basis. The phenomenon of alien abduction, presumed to be of archetypal origin, is discussed as an example. (shrink)

La traduction de l'epistrophe grecque en conversio latine a pu laisser entendre une continuite entre le retour des philosophies grecques neoplatoniciennes et l'evenement religieux proprement chretien de la conversion. Le paradigme en serait le passage de Plotin a Augustin. Mais peut-on oublier que les grecques classiques n'ont pas d'ethique du repentir et que, sans ce rapport au temps de la faute, la constitution de soi n'a ni le meme sens ni le meme lieu? C'est le travail du Centre A.J. Festugiere (...) de Paris X-Nanterre sur les entrecroisements et reprises entre philosophie et religion qui est a l'origine des etudes rassemblees en cet ouvrage. Que nous voyions apparaitre aujourd'hui une nouvelle forme de repentir publique convie a mieux distinguer deux modeles de constitution de soi qui se reconnaissent en ce que l'accent porte tantot sur l'etre et tantot sur le temps.

Das Handbuch führt erstmals die vielseitigen Traditionen der Emotionsforschung zusammen. Den Anfang macht eine historische Betrachtung der Emotions- und Affekttheorien von der Antike bis zur Moderne. Dem folgt eine umfassende Übersicht zentraler Emotionskonzepte der Gegenwart, wie sie in Psychologie und Philosophie diskutiert werden. Vor dem Hintergrund dieser Konzepte und ihrer historischen Verortung entfaltet das Handbuch eine umfassende Typologie der Emotionen. Verschiedenste Komplexe – wie etwa Trauer, Melancholie und Depression oder Freude, Glück und Wohlbefinden – werden jeweils in den Sichtweisen unterschiedlicher (...) Disziplinen dargelegt, darunter Ethnologie, Philosophie, Literaturwissenschaft, Soziologie, Psychologie. Abschließend werden entlang zentraler Konzepte wie Sprache, Kultur, Politik und Medien vier wesentliche Fluchtlinien aktueller Emotionsforschung entfaltet, welche den Horizont einzelner Disziplinen überschreiten und entsprechend in interdisziplinärer Perspektive erschlossen werden.
