We have developed an example of hydrocarbon detection for an Ordovician cavern carbonate reservoir in western China with a burial depth exceeding 6600 m using amplitude variation with offset and spectral decomposition. We selected six production wells, three prolific oil wells, and three brine wells to test the hydrocarbon detection method. The three oil wells have been producing for more than three years, and the three water wells only produce brine. We performed spectral decomposition to the angle gathers and analyzed (...) amplitude variation patterns with incidence angles for different spectral components. Specifically, we compared the time corresponding to the peak spectral amplitude for different spectral components for the oil- and brine-saturated carbonate reservoirs. The main findings are as follows: Oil-saturated cavern carbonate reservoirs show decreasing peak time with increasing frequency; i.e., the high-frequency components travel faster than do the low-frequency components. The maximum time difference between the 10 and 50 Hz spectral components could reach 35 ms. In contrast, the brine-saturated carbonate reservoirs do not exhibit conspicuous variation in the peak time, AVO attributes extracted from the low-frequency spectral gathers are more robust than those extracted from the original seismic gathers, oil-saturated cavern carbonate reservoirs cause strong energies in the low-frequency spectral components and severe attenuation to the high-frequency spectral components at large incidence angles. In contrast, the brine-saturated carbonate reservoirs do not produce such phenomenon. Rock physics analysis for carbonate reservoirs under different saturation conditions was conducted. The synthetic gathers were generated for carbonate reservoirs under oil- and brine-saturated conditions. The spectrally decomposed synthetic gathers are in agreement with the real gathers. The results indicate that AVO analysis of spectrally decomposed prestack gathers could be used as an effective hydrocarbon detection method for carbonate reservoirs. (shrink)
Hao Wang was one of the few confidants of the great mathematician and logician Kurt Gödel. _A Logical Journey_ is a continuation of Wang's _Reflections on Gödel_ and also elaborates on discussions contained in _From Mathematics to Philosophy_. A decade in preparation, it contains important and unfamiliar insights into Gödel's views on a wide range of issues, from Platonism and the nature of logic, to minds and machines, the existence of God, and positivism and phenomenology. The impact of (...) Gödel's theorem on twentieth-century thought is on par with that of Einstein's theory of relativity, Heisenberg's uncertainty principle, or Keynesian economics. These previously unpublished intimate and informal conversations, however, bring to light and amplify Gödel's other major contributions to logic and philosophy. They reveal that there is much more in Gödel's philosophy of mathematics than is commonly believed, and more in his philosophy than his philosophy of mathematics. Wang writes that "it is even possible that his quite informal and loosely structured conversations with me, which I am freely using in this book, will turn out to be the fullest existing expression of the diverse components of his inadequately articulated general philosophy." The first two chapters are devoted to Gödel's life and mental development. In the chapters that follow, Wang illustrates the quest for overarching solutions and grand unifications of knowledge and action in Gödel's written speculations on God and an afterlife. He gives the background and a chronological summary of the conversations, considers Gödel's comments on philosophies and philosophers, and his attempt to demonstrate the superiority of the mind's power over brains and machines. Three chapters are tied together by what Wang perceives to be Gödel's governing ideal of philosophy: an exact theory in which mathematics and Newtonian physics serve as a model for philosophy or metaphysics. Finally, in an epilog Wang sketches his own approach to philosophy in contrast to his interpretation of Gödel's outlook. (shrink)
In this first extended treatment of his life and work, Hao Wang, who was in close contact with Godel in his last years, brings out the full subtlety of Godel's ideas and their connection with grand themes in the history of mathematics and ...
This cogent and knowledgeable critique of the tradition of modern analytic philosophy focuses on the work of its central figures -- Russell, Carnap, and Quine -- and finds it wanting. In its place, Hao Wang unfolds his own original view of what philosophy could and should be. The base of any serious philosophy, he contends, should take as its point of departure the actual state of human knowledge. He explains the relation of this new tradition to mathematical logic and (...) reveals the crucial transitions and mistakes in mainstream Anglo-American philosophy that make a new approach so compelling.Equally at home in philosophy and mathematics, Wang is uniquely qualified to take on the task of critically examining modern philosophy. He carefully traces the path of ideas from Russell and Wittgenstein through the Vienna Circle to modern British and American philosophy, and makes use of his familiarity with the profound thought of Kurt Gödel with whom he has had numerous discussions. He also presents the broader significance of Russell's philosophy, provides a comprehensive and unified treatment of Quine's work in logic and in philosophy, and delineates what is common between Carnap and Quine.

The suppression of sexuality is culturally widespread, and women’s sexual promiscuity, activity, and enjoyment are almost always judged and punished more harshly than men’s. It remains disputed, however, to what end people suppress sexuality, and who benefits from the suppression of female sexuality. Different theories predict that women in general, men in general, women’s intimate partners, or parents benefit most. Here we use the lies women and men tell—or imagine telling—about their sexual histories as an indirect measure of who is (...) most involved in the suppression of sexuality. We asked men and women what they would reply if asked questions by their mother, father, current partner, attractive confederate, and various same- or opposite-sex friends and colleagues about their number of previous sex partners, age at first romantic kiss, age at first consensual sex, and cheating on a previous partner or spouse. By comparing the size and direction of the lies that subjects told, we tested competing predictions of several cultural and evolutionary theories concerning why female sexuality is suppressed and who is driving its suppression. We found that men and women told larger and more frequent lies to their parents, with women telling the largest and most frequent lies of all to their fathers. Additionally, the majority of lies by both men and women were in sexually conservative directions. Our findings suggest that mothers, and especially fathers, restrict female sexuality. (shrink)
In (2011) McLeod suggested that the first century Chinese philosopher Wang Chong 王充 may have been a pluralist about truth. In this reply I contest McLeod's interpretation of Wang Chong, and suggest "quasi-pluralism" (albeit more as an alternative to pluralism than as an interpretation of Wang Chong), which combines primitivism about the concept of truth with pluralism about justification.
Most ethicists have paid little attention to the rhetorical features of case presentations. In order to examine the constructed nature of bioethics cases, this paper examines the literary characteristics of four presentations of Donald “Dax” Cowart's story. By comparing tellings of the same case, a pattern of redaction is revealed by which the tellers conceal the very features that would challenge the perspectives taken in their arguments. In conclusion, the issue of the applied nature of bioethics is examined.
Within various contexts, such as politics and parenting, Confucianism has been criticized on the basis that it endorses ‘unquestioning obedience’ to authorities. In recent years, several philosophers have argued against this view by appealing to textual evidence from Classical Confucian philosophers. In this essay, I examine Wang Yangming’s views on this subject, arguing that Wang teaches that criticism of those who stand in a socially superior role relation is not only permitted, but encouraged. From this, I consider the (...) implications that Wang’s analysis has for contemporary discussions of disagreement between epistemic superiors and inferiors and epistemic peerhood. I will argue that Wang’s position is much closer to the total evidence view than the preemptive view. Relatedly, I will suggest that Wang provides a novel proposal about how to recognise or disregard epistemic ‘superiors’, especially in the context of moral knowledge. (shrink)
Through a comparative analysis of diverse texts and contexts, this book offers a cultural history of the interplay between the aesthetic and the political in the formation of personal and collective identity that crystallizes into the Chinese aesthetic of the sublime. It describes how various kinds of politics are aestheticized and how aesthetic manifestations are bound up with prevalent ideologies and politics. In this book, politics refers to various projects for fashioning a viable self, a workable personal and collective identity (...) in the crisis-ridden history of modern China. These projects include imagining a political subject adapted to the modern nation-state, mobilizing revolutionary masses as subjects of the Communist state, sustaining a unified self despite the challenges to traditional culture, erecting the sublime figure of the revolutionary hero, and, finally, debunking the grand images of the hero and history in post-Mao culture. Throughout, the author seeks to delineate the ways the political masquerades as aesthetic discourse and aesthetic experience. Covering a wide range of material from fiction, poetry, aesthetics, and political discourse to memoirs, film, and historical documents, the book reconsiders a number of prominent cultural figures, including Wang Guowei, Cai Yuanpei, Lu Xun, Eileen Chang, Mao Zedong, Zhu Guangqian, and Li Zehou. It also analyzes such important cultural features and events as Western influences on the formation of modern Chinese aesthetic discourse, modernist writings, Revolutionary Cinema, the Cultural Revolution, and New Wave Fiction. An East-West comparative approach informs the analysis, which engages in dialogue with Kant, Hegel, Freud, Marx, and Walter Benjamin, as well as Terry Eagleton and other contemporary critics. The author's interdisciplinary method, which emphasizes the interaction among text, context, and the psyche, both presents new materials and illuminates familiar texts and phenomena from the perspective of the political-aesthetic nexus.

The activity of synsedimentary faults plays an important role in controlling the distribution of sand bodies in basins and furthermore the porosity and permeability of reservoirs. We have used fault interpretation, the method of image and granularity size analysis, and the seismic pumping effect to investigate the control of the activity of the Kongdong fault on the development degree of the dissolution pores and grain size, further studying the controlling mechanism of the activity of synsedimentary faults on reservoir quality. The (...) results showed that the slip rate of synsedimentary faults is one of the main factors in controlling reservoir quality. The slip rate controls the accommodation space and hydrodynamic conditions and it furthermore controls the grain size. The higher the slip rate, the bigger the grain size in the downthrow wall of synsedimentary faults; the seismic pump produced by synsedimentary faults activity also controls the development degree of dissolution pores. The development degree of dissolution pores in the downthrown wall of synsedimentary faults is greater than that in the upthrown wall. Dissolution pores are more developed in areas with a large slip rate of synsedimentary faults. Porosity increases gradually with the increase of plane porosity of dissolution pores, whereas the changes of permeability are not obvious. (shrink)
A fundamental way in which human thought has developed has been constantly to explain the earliest "classics" that are the source of that thought. All in all, the number of such classics is not very high, their explanations are past counting. Moreover, they are constantly increasing, giving rise to an explanatory chain deriving from the classics. In the development of Chinese philosophy, this aspect is particularly noticeable, so that one can describe Chinese philosophy as a continual explanation of the classics. (...) This holds for both Confucianism and Daoism. The main classics of Daoism are the Laozi and the Zhuangzi. These two works have been constantly reread and reinterpreted throughout history. From the late nineteenth century onward, Chinese philosophy came into closer contact with Western philosophy. Foreign concepts were brought in to provide philosophers with new "insight." Some thinkers applied this new insight or these foreign concepts to the Daoist classics. In this way, they brought a new explanation of the Daoist classics and enriched the ways of interpreting the texts.1 Paving the way in this direction were Yan Fu. Zhang Taiyan, Liang Qichao, Wang Guowei, and Hu Shi. (shrink)

In this paper we analyses the work of the first century Chinese philosopher Wang Chong as in part grappling with epistemology of testimony. Often portrayed as a curmudgeonly skeptic, Wang Chong actually best seen as a demanding piecemeal non-reductionist, which is to say he believed that testimony was a basic source of evidence unless subject to a defeater (non-reductionism), but also that we should evaluate testimony on a claim-by-claim basis (piecemeal) rather than accepting a whole source on the (...) strength of its reputation or authority, and finally he thought one has a strong duty to search for defeaters (demanding). We defend each of these claims as well as the fruitfulness of applying such anachronistic terminology to an ancient thinker. We end with a discussion of how Wang Chong's epistemology relates to his rhetorical method and then consider some problems he faces because of his epistemic commitments. (shrink)
