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)

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.

'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)

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)

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.

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.

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)

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.

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.

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.

Allen begins with a general survey of "atheism and atheists" in the Renaissance, gives brief sketches of six individual "atheists"—Pomponazzi, Cardano, Vanini, Montaigne, Charron, Bodin—devotes chapters to rational theology against atheism and to reason and immorality, and closes with a portrait of the "atheist redeemed" in the person of the Earl of Rochester, the arch-rake of the Restoration who was converted during his final illness. He points out that during this period "atheist" usually meant no more than a person whose (...) theology did not agree fully with that of the name-caller, and that none of the thinkers he mentions merited the term in any strict sense. The book is a wide-ranging, erudite survey without much attempt at either analysis in depth or synthesis, but Allen's somewhat Voltairean point of view helps give it form.—W. B. K. (shrink)

Multi-point Temperature Measurement has always been very important aspect of physical instrumentation mainly in environmental and Industrial application. A multi-point temperature measurement system has been developed to measure temperature at different points simultaneously. This multi-channel system is designed specifically for measuring snow temperature at 28 different points In snow layers and this multi-point data is used in modeling of snow cover. The interfacing of such multi-channel system to Data acquisition system is one of the most critical design aspects, which affect (...) the overall performance of the system. The temperature sensor system and Data Acquisition System may be working satisfactorily when operated independently but total system integrity is absolutely important when these two sub-systems are interfaced together. Further operating conditions in snow causes many performance and reliability issues to be tackled through proper design. This paper discusses the design aspects involved in the interfacing of the multi-channel temperature measurement system with the Data Acquisition System specifically for Snow hydrological applications.

The marketing culture is essential for improving performance in the highly competitive restaurant industry. It investigates the effectiveness of marketing culture dimensions on the performance of restaurants in the competitive restaurant industry. The data was gathered from 298 respondents of managers and employees across 48 restaurants using a structured questionnaire. Partial Least Squares Structural Equation Modeling (PLS-SEM) was used to evaluate the connections between these constructs. The measurement model assessment was validated using indicators such as Average Variance Extracted (AVE), Composite (...) Reliability, and Cronbach’s Alpha. The structural model assessment investigation's strategy hypothesized connections were also tested using evaluations of five structural path frameworks. The findings demonstrate that all five dimensions of marketing culture positively and significantly impact restaurant performance. Sales strategy had the strongest influence, followed by innovation potential, quality of service, organizational structure, and leadership-staff collaboration. All hypothesized relationships were supported with significant path coefficients, T-values, and p-values. The study emphasizes the importance of a robust marketing culture in enhancing restaurant performance and suggests that restaurant managers should prioritize the development of effective sales strategies and foster innovation within their marketing culture.
