Thirteen essays on the treatment of a criterion for truth by such classical writers as Parmenides, Protagoras, Plato, Aristotle, Theophrastus, Philo, Epicurius, the Stoics, Plotinus, and Ptolemy, whose neglected Greek work on the subject is included here, along with an annotated English translation. The price $LB12.50, has been estimated to US $24. Annotation copyrighted by Book News, Inc., Portland, OR.

The systems approach to niche presented herein stands as an example of the unifying potential of mathematical system theory when applied to concepts and principles of ecology. Beginning with subjective concepts from the naturalistic tradition, the niche was framed in the formalism of general system theory. So modeled, it appeared as a restriction of a more general construct, the environ. Both niches and environs are implementable in the context of ecosystem models, and with the growing ability of ecologists to construct (...) such models, system theoretic niches and environs both should serve in the future to clarify old problems of ecology, and make it possible to raise new classes of problems. The nature of niches, always difficult conceptually for the ecologist, may now give way to further development, both theoretical and empirical. (shrink)

All-encompassing text examines every aspect of coma from neurochemistry, monitoring, and treatments to prognostic factors.

This volume of the Great American Thinkers series purports to let Thoreau speak for himself, primarily through passages quoted from his journals. Originally published in fourteen volumes, the journals represent over twenty years of Thoreau's life, and are the background and, in some cases, the original form of works more polished and more widely known. Murray has aptly considered Thoreau's wide range of thought and comment under several main headings, such as "Primacy or Purpose," "Society as Burden," and "Freedom and (...) Simplicity." In this arrangement, many of Thoreau's specific and often curt observations can be seen in a more general context, with Thoreau himself providing some of the keys to the transition.--G. B. S. C.

In conveying experiences of meditation, the question of what exceeds or should resist description has been a recurrent topic of commentary in a wide array of literature -- including religious doctrine, meditation guides, and contextual accounts written by historians and social scientists. Yet, to date, this question has not significantly informed neuroscientific studies on the effects of meditation on brain and behaviour, in large part -- but not wholly -- because of the disregard for first-person accounts of experience that still (...) characterizes neuroscience in general. By juxtaposing perspectives from non-neuroscientific accounts on the tensions and questions raised by what is and is not expressed or expressible in words, this article paves the way for a new set of possibilities in experimental contemplative neuroscience.

Bizarre delusions are not specific to schizophrenia and can be found in other psychotic disorders. However, to date, there are no studies investigating socio-demographic and clinical characteristics associated with BizD across the psychosis spectrum. In this study 819 subjects with a diagnosis of SZ, schizoaffective disorder and bipolar I disorder were included. Patients with history of BizD and with no BizD were compared with respect to socidemographic and clinical variables, and predictors of BizD were explored. Patients with BizD were less (...) educated, less likely to be married, had higher Positive and Negative Syndrome Scale negative scores and lower Young Mania Rating Scale scores. Younger age, SZ and SZA diagnoses, higher PANSS positive scores, presence of reference delusions, tactile and olfactory hallucinations were predictors. Our results indicate that BizD are associated with higher illness severity, lower functionality and specific set of symptoms. (shrink)

Knowledge of mechanisms is critical for causal reasoning. We contrasted two possible organizations of causal knowledge—an interconnected causal network, where events are causally connected without any boundaries delineating discrete mechanisms; or a set of disparate mechanisms—causal islands—such that events in different mechanisms are not thought to be related even when they belong to the same causal chain. To distinguish these possibilities, we tested whether people make transitive judgments about causal chains by inferring, given A causes B and B causes C, (...) that A causes C. Specifically, causal chains schematized as one chunk or mechanism in semantic memory led to transitive causal judgments. On the other hand, chains schematized as multiple chunks led to intransitive judgments despite strong intermediate links. Normative accounts of causal intransitivity could not explain these intransitive judgments. (shrink)

© 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)

Plato's Sophist begins with an attempt to arrive by division at a definition of a Sophist. In the course of the attempt six different descriptions are discussed and the results summarized at 231 c-e. A seventh and final account may be said to occupy the whole of the rest of the dialogue, including the long digression on negative statements. The first five divisions characterize with a considerable amount of satire different types of sophist, or more probably different aspects of the (...) sophistic art. The sixth division is very different. To quote Cornford's words, ‘satire is dropped. The tone is serious and sympathetic, towards the close it becomes eloquent’. (shrink)

This out of print work offered researchers a comprehensive and easy to use bibliography of primary and secondary works by or about Collingwood. More than 1,200 citations were listed alphabetically by standard bibliographical categories in this volume, which contained a periodical index as well as author and subject indexes. In addition, each book entry included a "review alert" listing the names of reviewers. Author notes clarified the significance of a listed work when this was not apparent from the title, and (...) the number of pages was indicated for very long or very short monographs. This volume remains a standard reference work for Collingwood scholars and it is available in research libraries around the country. (shrink)

This article provides ethical guidance on using race in health research as a variable or in defining the study population. To this end, a plain, non-exhaustive checklist is provided for researchers and research ethics committees, preceded by a brief introduction on the need for justification when using race as a variable or in defining a study population, the problem of exoticism, that distinctions pertain between race, ethnicity and ancestry, the problematic naming of races, and that race does not serve well (...) as a presumed biological construct in genetic research.

There are two types of fluctuations in the quantum vacuum: type 1 vacuum fluctuations are on shell and can interact with matter in specific, limited ways that have observable consequences; type 2 vacuum fluctuations are off shell and cannot interact with matter. A photon will polarize a type 1, bound, charged lepton–antilepton vacuum fluctuation in much the same manner that it would polarize a dielectric, suggesting the method used here for calculating the permittivity $$\epsilon _{0}$$ϵ0 of the vacuum. In a (...) model that retains only leading terms, $$\epsilon _{0} \cong ^{2}= 9.10\times 10^{-12}$$ϵ0≅2=9.10×10-12 C/. The calculated value for $$\epsilon _{0}$$ϵ0 is 2.7% more than the accepted value. The permittivity of the vacuum, in turn, determines the speed c of light in the vacuum. Since the vacuum is at rest with respect to every inertial frame of reference, c is the same in every inertial reference frame. (shrink)
