An important influence on Jean-Luc Marion’s phenomenology is the work of Swiss Catholic theologian Hans Urs von Balthasar. Marion is particularly interested in Balthasar’s ‘phenomenological’ approach to the content of Christian revelation, centered on the metaphor of the work of art. Balthasar suggests in his Theo-Logic that the early Marion ‘concede[s] too much to the critique of Heidegger,’ moving too far away from the ‘transcendental’ metaphysics of Aquinas and the classical tradition. Yet Balthasar’s criticism is premature. Rather, Marion’s work, particularly (...) his emphasis on the ‘saturated phenomenon,’ paves the way for a postmetaphysical theological aesthetics that might renew Balthasar’s project in a cultural situation ‘after’ the death of God, while simultaneously opening a space for Christian revelation apart from a certain hegemonic tradition of onto-theology.

"Parts of Classes" tries to separate the unproblematic part of set theory (mereology) from the problematic part (singletons). In the process several things get lost: an empty set which is really empty; a satisfying account of the paradoxes; and the motivation for the iterative conception of set. Lewis' attack on the coherence of singletons makes it puzzling what he sees his book as doing. Nor is it clear that mereology is as ontologically innocent as Lewis would have us believe.
This collection of thirteen essays, when viewed together, offers a unique perspective on the history of American philosophy. It illuminates for the first time in book form, how thirteen major American philosophical thinkers viewed a problem of special interest in the American philosophical tradition: the relationship between experience and reflection. Written by well-known authorities on the figure about which he or she writes, the essays are arranged chronologically to highlight the changes and developments in thought from Puritanism to Pragmatism to (...) Process Philosophy. While Doctrine and Experience will be of particular interest to specialists in American Philosophy, there is also much to offer anyone interested in the intellectual and cultural history of the United States. In order of appearance, the essays are: "Jonathan Edwards and the Great Awakening" by John E. Smith "Heart and Head: The Mind of Thomas Jefferson" by Andrew J. Reck"Emerson and the American Future" by Robert C. Pollock"Chauncey Wright and the Pragmatists" by Edward Madden"Charles S. Peirce: Action Through Thought – The Ethics of Experience" by Vincent G. Potter"Life Is in the Transitions’: Radical Empiricism and Contemporary Concerns" by John J. McDermott"John Dewey and the Metaphysics of American Democracy" by Ralph W. Sleeper"Individualization and Unification in Sartre and Dewey" by Thelma Z. Levine"Josiah Royce: Anticipator of European Existentialism and Phenomenology" by Jacqueline Ann K. Kegley"The Transcendence of Materialism and Idealism in American Thought" by John Lachs"C. I. Lewis and the Pragmatic Tradition in American Philosophy" by Sandra Rosenthal"The Social Philosophy of George Herbert Mead" by David Miller"Existence as Transaction: A Whiteheadian Study of Causality" by Elizabeth Kraus.

Large-scale 3D modeling of realistic earth models is being increasingly undertaken in industry and academia. These models have proven useful for various activities such as geologic scenario testing through seismic finite-difference modeling, investigating new acquisition geometries, and validating novel seismic imaging, inversion, and interpretation methods. We have evaluated the results of the Western Australia Modeling project, involving the development of a large-scale 3D geomodel representative of geology of the Carnarvon Basin, located offshore of WA’s North West Shelf. Constrained by a (...) variety of geologic, petrophysical, and field seismic data sets, the viscoelastic WAMo 3D geomodel was used in seismic FD modeling and imaging tests to “validate” model realizations. Calibrating the near-surface model proved to be challenging due to the limited amount of well data available for the top 500 m below the mudline. We addressed this issue by incorporating additional information as well as by using soft constraints to match the overall character of nearby NWS seismic data with the modeled shot gathers. This process required undertaking several “linear” iterations to apply near-surface model conditioning, as well as “nonlinear” iterations to update the underlying petrophysical relationships. Overall, the resulting final WAMo 3D geomodel and accompanying modeled shot gathers and imaging results are able to reproduce the complex full-wavefield character of NWS marine seismic data. Thus, the WAMo model is well-calibrated for use in geologic and geophysical scenario testing to address common NWS seismic imaging, inversion, and interpretation challenges. (shrink)
A key goal in industry and academic seismic research is overcoming long-standing imaging, inversion, and interpretation challenges. One way to address these challenges is to develop a realistic 3D geomodel constrained by local-to-regional geologic, petrophysical, and seismic data. Such a geomodel can serve as a benchmark for numerical experiments that help users to better understand the key factors underlying — and devise novel solutions to — these exploration and development challenges. We have developed a two-part case study on the Western (...) Australia Modeling project, which discusses the development and validation of a detailed large-scale geomodel of part of the Northern Carnarvon Basin located on WA’s North West Shelf. Based on the existing regional geologic, petrophysical, and 3D seismic data, we develop the 3D geomodel’s tectonostratigraphic surfaces, populate the intervening volumes with representative geologic facies, lithologies, and layering as well as complex modular 3D geobodies, and generate petrophysical realizations that are well-matched to borehole observations point-wise and in terms of vertical and lateral trends. The resulting 3D WAMo geomodel is geologically and petrophysically realistic, representative of short- and long-wavefield features commonly observed in the NCB, and leads to an upscaled viscoelastic model well-suited for high-resolution 3D seismic modeling studies. In the companion paper, we study WAMo seismic modeling results that demonstrate the quality of the WAMo geomodel for generating shot gathers and migration images that are highly realistic and directly comparable with those observed in NCB field data.

We have trained deep convolutional neural networks to accelerate the computation of seismic attributes by an order of magnitude. These results are enabled by overcoming the prohibitive memory requirements typical of 3D DCNs for segmentation and regression by implementing a novel, memory-efficient 3D-to-2D convolutional architecture and by including tens of thousands of synthetically generated labeled examples to enhance DCN training. Including diverse synthetic labeled seismic in training helps the network generalize enabling it to accurately predict seismic attribute values on field-acquired (...) seismic surveys. Once trained, our DCN tool generates attributes with no input parameters and no additional user guidance. The DCN attribute computations are virtually indistinguishable from conventionally computed attributes while computing up to 100 times faster. (shrink)
This study explores the role that news coverage plays in the allocation of Japanese development aid. Conceptually, it is expected that democratic foreign policy officials, including those working in bureaucratic governmental structures will try to match the magnitude of their actions with what they expect is the public's perception of the importance of the recipient. News media salience serves an easily accessible indicator of that domestic political importance and, in the case of foreign aid, this suggests that higher levels of (...) news coverage of a less-developed country will lead to higher aid commitments. The statistical analysis demonstrates that the level of news coverage is a statistically significant factor in Japanese aid distributions. More significantly, the analysis demonstrates that separating grant aid from other forms of aid is critical for the empirical examination of the determinants of Japanese aid. (shrink)
Given that in any Roman aristocratic household during the Republic elements of the future imperial court can be found, what were the key features that enabled the latter to emerge and grow? Drawing upon Elias' analysis of court societies, this chapter maintains that the transition depends upon extraordinary religious charisma, access to renewable sources of immense wealth, and the development of integrative structures linking provincial and Roman supporters in a hierarchy dependent upon an individual rather than tenure of office.
This article examines a particular debate between Eamonn Callan and William Galston concerning the need for a civic education which counters the divisive pull of pluralism by uniting the citizenry in patriotic allegiance to a single national identity. The article offers a preliminary understanding of nationalism and patriotism before setting out the terms of the debate. It then critically evaluates the central idea of Callan that one might be under an obligation morally to improve one''s own patriotic inheritance, pointing to (...) the ineliminable tension between the valuation of one''s own patria by its own terms and a detached critical reason. It concludes by suggesting that we are, in advance of our education, members of a particular patria and that any education must be particularistic. Finally, the danger is noted of presuming that, in each case, there is a single, determinate national tradition. (shrink)
I am honoured and pleased to address you this evening on the life and work of an extraordinary American thinker, Charles Sanders Peirce. Although Peirce is perhaps most often remembered as the father of the philosophical movement known as pragmatism, I would like to impress upon you that he was also, and perhaps, especially, a logician, a working scientist and a mathematician. During his life time Peirce most often referred to himself, and was referred to by his colleagues, as a (...) logician. Furthermore, Peirce spent thirty years actively engaged in scientific research for the US Coast Survey. The National Archives in Washington, DC, holds some five thousand pages of Peirce's reports on this work. Finally, the four volumes of Peirce's mathematical papers edited by Professor Carolyn Eisele eloquently testify to his contributions to that field as well. (shrink)
