The frequency and temperature dependences of the ac conductivity and dielectric constant of the V 2 O 5 -MnO-TeO 2 system, containing two transition-metal ions, have been measured. The dc conductivity † dc measured in the high-temperature range decreases with addition of the oxide MnO. This is considered to be due to the formation of bonds such as V--O--Mn and Mn--O--Mn in the glass. The conductivity arises mainly from polaron hopping between V 4+ and V 5+ ions. It is found (...) that a mechanism of adiabatic small-polaron hopping is the most appropriate conduction model for these glasses. This is in sharp contrast with the behaviour of the Mn-free V 2 O 5 -TeO 2 glass, in which non-adiabatic hopping takes place. High-temperature conductivity data satisfy Mott's small-polaron hopping model and also a model proposed by Schnakenberg in 1968. A power-law behaviour † ac = A y s , with s < 1) is well exhibited by the ac conductivity † ac data of these glasses. Analysis of dielectric data indicates a Debye-type relaxation behaviour with a distribution of relaxation times. The MnO-concentration-dependent † ac data follow an overlapping large-polaron tunnelling model over the entire range of temperatures studied. The estimated model parameters are reasonable and consistent with changes in composition. (shrink)

Study with reference to Tattvacintāmaṇi of Gaṅgeśa, 13th cent.

Contributed articles presented at the International Seminar on Ultimate Reality and Meaning during July 2006 at Centre of Advanced Study in Sanskrit, University of Pune.

This study provides current data on key questions about retraction of scientific articles. Findings confirm that the rate of retractions remains low but is increasing. The most commonly cited reason for retraction was research error or inability to reproduce results; the rate from research misconduct is an underestimate, since some retractions necessitated by research misconduct were reported as being due to inability to reproduce. Retraction by parties other than authors is increasing, especially for research misconduct. Although retractions are on average (...) occurring sooner after publication than in the past, citation analysis shows that they are not being recognised by subsequent users of the work. Findings suggest that editors and institutional officials are taking more responsibility for correcting the scientific record but that reasons published in the retraction notice are not always reliable. More aggressive means of notification to the scientific community appear to be necessary. (shrink)

This paper addresses the changing ideology regarding reproduction, an evolving American, and potentially worldwide, value system regarding children and parenthood. Children are increasingly being seen as products, and the new technology of reproduction, including the sale of reproductive material and services and especially prenatal diagnosis and selective abortion, encourage this commodification of the fetus. While the new technology does indeed offer new choices, it also creates new structures and new limitations on choice. In the contemporary American social structure, these choices (...) are inevitably couched in terms of production and commodification, and thus do not offer individuals genuine choice or control.

Five Heads (1929–1930) and Actors in the Square (1969). An attempt was made to trace the external plan of the image in all its elements (form construction, figure composition, the characteristics of faces, the color landscape) and to reveal the internal plan, the figurative structure, which manifests itself in the play of the color surface, which performs a dual role: to be both an object shell and a screen, where associations that arose in the mind and imagination of the artist (...) in the process of work are visualized. The attempt to see and analyze how the interweaving of the two image planes (symbiosis, synthesis), their flowing into each other create a pulsating image of the work that touches the feelings of the viewer.

Книга посвящена системе миропонимания, которая называется Ноокосмология.

"The definitive work by B.K.S. Iyengar, the world's most respected yoga teacher. B.K.S. Iyengar has devoted his life to the practice and study of yoga. It was B.K.S. Iyengar's unique teaching style, bringing precision and clarity to the practice, as well as a mindset of 'yoga for all', which has made it into the worldwide phenomenon it is today. 'Light on Yoga' is widely called 'the bible of yoga' and has served as the source book for generations of yoga students (...) around the world. It is the classic text for all serious students of yoga." --Publisher description. (shrink)

Iyengar Yoga Wisdom & Practice" is a practical and an inspiring anthology of Iyengar's insights into yoga, life and the path to peace and happiness. Yoga practice lies at the heart of the book, and it is illustrated with over 60 new step-by-step sequences of yoga postures specially shot in India and accompanied by Iyengar's illuminating observations on technique, their significance, and their benefits. This book not only presents Iyengar's practical advice on how to perform key yoga postures, but also (...) draws on a wide range of other material taken from interviews and world lecture tours, to the many texts Iyengar has written about yoga and about his own life's journey.

Designed to complement the editors' earlier selection, The Social and Political Philosophy of Jacques Maritain, this book arranges its material in six sections: theory of knowledge, metaphysics, ethics, esthetics, politics, and philosophy of history, with the editors contributing a one-page or two-page introduction to each section. The texts, taken from some fifteen of Maritain's works and in some cases published for the first time in English, are well chosen and interesting in themselves, but are too brief to present fully developed (...) arguments. This raises the question of the audience being aimed at. The book is not coherent enough to serve as a serious introduction to Maritain or to modern Thomism; it is rather a "sampler," and might be most useful as a kind of bedside book for those already acquainted with Maritain.--W. B. K. (shrink)

These essays were originally presented at the first of an annual series of seminars in the humanities at John Hopkins. To avoid imposing an artificial unity on the subject, the contributors were deliberately left unguided in their choice of subject and method. The result of this policy is a rich and stimulating collection ranging from gardens to musicology. Reproductions of paintings and copious printings of musical scores show that no expense was spared to make the book as useful as possible. (...) Of greatest interest to philosophers are George Boas's witty demolition of "the age of reason" as a description for the period, J. A. Passmore on "the malleability of man," Isaiah Berlin's long reconsideration of Herder, Alfred Cobban on "the Enlightenment and the French Revolution," and Henry Guerlac on Newton's place in intellectual history.—W.

Although the essays in this book vary a good deal in quality, they all distort the eighteenth century to some extent by concentrating on its "modernity," about the scope of which, to increase the confusion, none of the authors is very explicit. One essay treats the emergence of scientific thought quite superficially; another presents Jacobi as an anti-type of Goethe and a fore-runner of existentialism. Herbert Dieckmann argues against the common "from classic to romantic" view of eighteenth-century aesthetic history. Ernest (...) Mossner characterizes "the enlightenment of David Hume," seeing him as a liberator of the mind from its various idols and reiterating his view that Hume was only a "mitigated sceptic." Dietrich Ritschl emphasizes Semler's contribution to the historical study of the Bible; his essay also contains, but only implicitly, some warnings for today's aggiornamento theologians.—W. B. K.

This historical study of the responses that man has tried to give to the problem of death-"If I must some day die, what can I do to satisfy my desire to live?" as defined by Fr. Dunne—is occasionally turgid but more often provocative and enlightening. From the dawn of history in Mesopotamia to the present, the book investigates the political and literary consequences of different answers to this question and of different attitudes toward death in general. Although the book's organization (...) is chronological, it is explicitly oriented to contemporary concerns, with Nietzsche's statement that "God is dead" serving as a unifying leit-motif. The most rewarding sections are the discussions of Homer's epics and the analysis of the confusions between the right to life and the right over life that are traced from Calvin, Luther, Hobbes, and Rousseau to modern totalitarianism.—W. B. K. (shrink)

Margolis's main concern is to clarify aesthetic terminology, and especially to distinguish between normative and descriptive uses of such terms as "taste" and "aesthetic." His own definition of a work of art, however, "an artifact considered with respect to its design," hardly improves on the definitions he criticizes. Some of the problems he discusses can be seen as versions of the One and the Many: e.g., the relation between a symphony and its different performances or between a poem and the (...) different interpretations it gives rise to. Among the more interesting chapters are those on figurative language and on "truth and reference in fiction."—W. B. K. (shrink)

Beardsley's exposition of his large subject shows lucidity, objectivity, deftness, and a good sense of proportion; and these virtues become more apparent the closer his history approaches the complex diversity of contemporary aesthetic speculation. Especially skillful are the succinct accounts of those aspects of each philosopher's thought which, though not directly concerned with aesthetics, are necessary for a full understanding of his aesthetic theories. Beardsley himself remains neutral, arguing neither for nor against the theories he analyzes. Some may feel that (...) the visual arts are slighted, but this is a minor criticism of a very informative and illuminating book.—W. B. K. (shrink)

Father Etcheverry examines four varieties of humanism: rationalist-idealist, existentialist, Marxist, and Christian. For each of the first three varieties he centers his analysis on one or two individuals: Leon Brunschvicg, Sartre and Camus, and Marx and Engels respectively. He writes as a committed Christian humanist, arguing that only a relationship with God enables man to become truly man. All other varieties of humanism prevent this full development by raising to absolute status one or another of man's essential properties—reason, liberty, matter, (...) sociability, etc.—and subordinating him too exclusively to that property alone.—W. B. K. (shrink)

West takes his title from Camus, and quotes Camus' definition of absurdity: "the division between the mind that desires and the world that disappoints." The essays, which originally appeared in periodicals, discuss Yeats, Lawrence, Sartre, Camus, Simon Weil, Graham Greene, Santayana, and other modern writers. There is no analysis, either philosophical or literary; West attempts overall estimates of each writer's contribution to the problem of absurdity, but succeeds in providing neither insights for those already familiar with the problem nor useful (...) introductions for the uninitiated. Nor, despite the expectations aroused by the preface, do we get a very strong impression of an individual's encounter with the thinkers from whom he has learned most. In vino vacuitas.—W. B. K.
