With the exploration of tight oil and gas, shallow-water deltaic reservoirs have been attracting more and more attention. The sedimentary architecture of a shallow-water delta shows (...) class='Hi'> distinctive differences with that of a deep-slope delta. These differences may be associated with the mechanism and characteristics of the deposition in the area where the sediments unloaded. Based on modern sedimentary research of the Poyang Lake in China, this paper focuses on the processes of river flow entering a lake with a low dip angle. We conducted six sets of numerical simulations with different initial sedimentary flow velocities using Fluent software for analyzing the hydrodynamics and the sediment transportation in the shallow-water delta. We combined the simulation results with an analysis of the geomorphology of the Gangjiang Delta to reveal the deposition along the shoreline of the lacustrine shallow-water delta. The numerical simulation shows that the shallow-water delta is dominated by bed friction with an extensive hydrodynamical boundary layer. The bed shear stress, which varies with the changes in river flux, dominated the sediment transport and deposition at the shallow-water delta front, where the effluent flow mixes with lake water. The distributary channels show characteristics of repeatedly occurred erosion, scouring, filling, and reoccupation. We argue that the depositional characteristics are associated with the changes in bed shear stress controlled by variation of flow velocity. Mouth bars are less likely to grow to a reasonable scale because of the seasonal scouring of extreme floods. Moreover, the lake flow potentially reworks the mouth bars. Consequently, mouth bar deposits were difficult to preserve as hydrocarbon reservoirs in ancient shallow-water delta. (shrink)

We model a black hole spacetime as a causal set and count, with a certain definition, the number of causal links crossing the horizon in proximity to (...) a spacelike or null hypersurface Σ. We find that this number is proportional to the horizon's area on Σ, thus supporting the interpretation of the links as the “horizon atoms” that account for its entropy. The cases studied include not only equilibrium black holes but ones far from equilibrium. (shrink)

The relationship between corporate social responsibility and corporate financial performance has long been a central and contentious debate in the literature. However, prior empirical studies provide indefinite (...) conclusions. The purpose of this study is to review systematically and quantify the CSR–CFP link in a meta-analytic framework. Based on 119 effect sizes from 42 studies, this study estimates that the overall effect size of the CSR–CFP relationship is positive and significant, thus endorsing the argument that CSR does enhance financial performance. Furthermore, this work sheds light on the causal relationship between CSR and CFP. Subsequent financial performance is associated with prior social responsibility, while the reverse direction is not supported. This finding supports the instrumental stakeholder theory. As predicted, the meta-analysis results indicate that the measurement strategies of the two key constructs of CSR and CFP explain some variations of the CSR–CFP relationship. Last, this study examines the moderating effect of the environmental context on the CSR–CFP link. This work proposes that CSR in the developed world, with a relatively mature institutional system and efficient market mechanism, will be more visible than CSR in the developing world. The results show that the CSR–CFP relationship is stronger for firms from advanced economies than for firms from developing economies. (shrink)

This research proposes an explanation for the conflicting extant evidence about whether family ownership of a business promotes proactive environmental strategy. Based on insights drawn from strategic (...) reference point theory, organizational identity theory, and the socioemotional wealth preservation perspective, we propose that family ownership has a moderated–mediated relationship with PES, with commitment as a moderator and long-term orientation as a mediator. A test using 454 China private firms with different levels of family ownership supports the hypotheses. This shows that PES as a strategy related to business ethics does not happen without commitment and long-term orientation. (shrink)

Accurate estimation of permeability for reservoir simulation and production is challenging in carbonate rocks due to the diversified pore structures resulting from deposition and diagenetic modification. A (...) significant amount of residue gas is expected in the Puguang field, China. We use a shear-frame flexibility factor [Formula: see text] from a rock-physics model as an index to quantify its spatial variation of pore structure and constrain the estimation of permeability in this field. The pore-structure index [Formula: see text] is established and used to classify various permeability-porosity trends at well locations where core and log data are available. It is found that when [Formula: see text], the pore type is dominated by intercrystalline pores with large pore-throat sizes and high connectivity, the permeability-porosity relation is [Formula: see text]; when [Formula: see text], the pore type consists of isolated moldic pores, the permeability-porosity relation is [Formula: see text], where [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] are constants, which are 80, 18, 3, 0.004, 5.5, and 1.6, respectively, for the studied gas reservoir. Rock-physics-based seismic inversion is then applied to quantify the spatial variation of pore type and permeability. The inversion results indicate that regional stratigraphy has a paramount control on the distribution of pore type and permeability. Moldic pores are widely distributed near the unconformities, whereas the large intercrystalline porosity and microporosity are distributed below and above the unconformities due to the sea-level regression and transgression, respectively. It is concluded that production problems may occur in porous and permeable intercrystalline-porosity zones and the exploration of residual gas remains in the high porosity yet less permeable moldic-porosity zones.

With the increasing volume of web services in the cloud environment, Collaborative Filtering- based service recommendation has become one of the most effective techniques to alleviate the (...) heavy burden on the service selection decisions of a target user. However, the service recommendation bases, that is, historical service usage data, are often distributed in different cloud platforms. Two challenges are present in such a cross-cloud service recommendation scenario. First, a cloud platform is often not willing to share its data to other cloud platforms due to privacy concerns, which decreases the feasibility of cross-cloud service recommendation severely. Second, the historical service usage data recorded in each cloud platform may update over time, which reduces the recommendation scalability significantly. In view of these two challenges, a novel privacy-preserving and scalable service recommendation approach based on SimHash, named SerRecSimHash, is proposed in this paper. Finally, through a set of experiments deployed on a real distributed service quality dataset WS-DREAM, we validate the feasibility of our proposal in terms of recommendation accuracy and efficiency while guaranteeing privacy-preservation.

In two recent papers, Mr Robert Young maintains that all attempts by philosophers to bolster the-violation-of-law concept of miracles are bound to fail and propounds (...) what he claims to be a novel non-reductivist concept of miracles which avoids the conceptual difficulties of the violation-model. His view of miracles is of god being ‘an active agent-factor in the set of factors which actually was causally operative’ [p. 123] in an event dubbed a miracle. God is put in among ‘the plurality of causes’ [p. 122, S p. 33] that could determine the event, but if he acts in a miracle, then ‘his presence…alters the outcome from what it would have been if, contrary to fact , he had not been present’ [p. 122]. Young claims that his concept ‘is neither a violation of … laws nor is it a coincidental occurrence religiously interpreted’ [p. 122, S p. 33], and so it avoids the difficulties, which he thinks are faced by the violation-model, of having an intelligible notion of an occurrence of the physically impossible, and also the reductivism inherent in taking mere coincidences as miracles. He also suggests a procedure of settling the epistemological issue regarding particular alleged miracles, an inquiry he thinks he has made possible by having first given a sense to miracles. [p. 126]. (shrink)

Research has indicated that microRNAs (miRNAs), a special class of non-coding RNAs (ncRNAs), can perform important roles in different biological and pathological processes. miRNAs’ functions are (...) class='Hi'>realized by regulating their respective target genes (targets). It is thus critical to identify and analyze miRNA-target interactions for a better understanding and delineation of miRNAs’ functions. However, conventional knowledge discovery and acquisition methods have many limitations. Fortunately, semantic technologies that are based on domain ontologies can render great assistance in this regard. In our previous investigations, we developed a miRNA domain-specific application ontology, Ontology for MIcroRNA Target (OMIT), to provide the community with common data elements and data exchange standards in the miRNA research. This paper describes (1) our continuing efforts in the OMIT ontology development and (2) the application of the OMIT to enable a semantic approach for knowledge capture of miRNA-target interactions.

Many languages have particles that possess multiple logical functions. Take the Mandarin particle dou for example. Varying by the item it is associated with and the prosodic (...) pattern of the environment it appears in, dou can trigger a distributivity effect, license a pre-verbal free choice item, or evoke an even-like inference. Considering universal grammar a simple system, we need to figure out, for a multi-functional particle, which of its functions is primary, what parametric variations are responsible for the alternations in function, and how these variations are conditioned. In this paper, I argue that the seemingly unrelated functions of dou share the same source: dou is a pre-exhaustification exhaustifier operating on sub-alternatives. Uniformly, dou affirms the truth of its propositional prejacent, negates the exhaustification of each sub-alternative, and presupposes a non-vacuity inference that there is at least one sub-alternative. Alternations in function result from minimal weakening operations on the semantics of sub-alternatives. In particular, sub-alternatives are primarily weaker alternatives, and the non-vacuity presupposition of dou yields a distributivity effect. When the semantics of sub-alternatives is weakened under particular syntactic or prosodic conditions, dou gains its other logical functions. (shrink)

Drawing on institutional and signaling theories, this study examines how environmental corporate social responsibility affects firm performance in a dysfunctional institutional environment. We extend the ECSR literature (...) by suggesting that ECSR indirectly influences firm performance through the mediating effects of business and political legitimacy. Based on a dataset of 238 firms in China, we find that ECSR affects business and political legitimacy followed by firm performance. Moreover, legal incompleteness weakens and legal inefficiency strengthens the effects of ECSR on business and political legitimacy. (shrink)

This essay develops an inferential account of model explanation, based on Mauricio Suárez’s inferential conception of scientific representation and Alisa Bokulich’s counterfactual account of model explanation (...) class='Hi'>. It is suggested that the fact that a scientific model can explain is essentially linked to how a modeler uses an established model to make various inferences about the target system on the basis of results derived from the model. The inference practice is understood as a two-step activity, with the first step involving making counterfactual statements about the model itself and the second step involving making hypothetical statements transferring over claims derived from the model onto the target. To illustrate how this two-step activity proceeds, an agent-based simulation model is discussed. (shrink)

This book presents a systematic account of the role of the personal spiritual ideal of wu-wei--literally "no doing," but better rendered as "effortless action"--in early (...) Chinese thought. Edward Slingerland's analysis shows that wu-wei represents the most general of a set of conceptual metaphors having to do with a state of effortless ease and unself-consciousness. This concept of effortlessness, he contends, serves as a common ideal for both Daoist and Confucian thinkers. He also argues that this concept contains within itself a conceptual tension that motivates the development of early Chinese thought: the so-called "paradox of wu-wei," or the question of how one can consciously "try not to try." Methodologically, this book represents a preliminary attempt to apply the contemporary theory of conceptual metaphor to the study of early Chinese thought. Although the focus is upon early China, both the subject matter and methodology have wider implications. The subject of wu-wei is relevant to anyone interested in later East Asian religious thought or in the so-called "virtue-ethics" tradition in the West. Moreover, the technique of conceptual metaphor analysis--along with the principle of "embodied realism" upon which it is based--provides an exciting new theoretical framework and methodological tool for the study of comparative thought, comparative religion, intellectual history, and even the humanities in general. Part of the purpose of this work is thus to help introduce scholars in the humanities and social sciences to this methodology, and provide an example of how it may be applied to a particular sub-field.

We investigate the cross-correlations of return-volume relationship of the Bitcoin market. In particular, we select eight exchange rates whose trading volume accounts for more than 98 (...) class='Hi'>% market shares to synthesize Bitcoin indexes. The empirical results based on multifractal detrended cross-correlation analysis reveal that the nonlinear dependencies and power-law cross-correlations in return-volume relationship are found; all cross-correlations are multifractal, and there are antipersistent behaviors of cross-correlation for q=2; the price of small fluctuations is more persistent than that of the volume, while the volume of larger fluctuations is more antipersistent; and the rolling window method shows that the cross-correlations of return-volume are antipersistent in the entire sample period.

Using a parallel mixed-methods design, the current study examined university students’ perceptions of academic cheating through collecting and analyzing both the quantitative and qualitative data. Our (...) class='Hi'>quantitative findings corroborate previous research that male students have engaged more in academic cheating than females based on students’ self-reports, and that undergraduate students are less willing to discuss issues on academic cheating as compared with their graduate counterparts. Five themes emerged from the thematic analysis of the qualitative data: flexible definitions for cheating, environmental promotion of cheating, the moral transgression of cheating, cheating as an ambiguous justification, and cheating as a conscious decision making process. The mixed-methods findings indicate that there is no relationship between students’ gender or classification and their endorsements of the qualitative themes. However, non-White students are more likely to endorse the theme “cheating as an ambiguous justification.” Implications for reducing and preventing academic cheating at the university level are discussed.

In recent years, philosophical ideas developed during the Wei-Jin period, broadly referred to as xuanxue in Chinese and ‘Neo-Daoism’ or ‘Dark Learning’ in English, have been (...) class='Hi'> accorded increasing attention in academia. This article provides an introduction to some major thinkers of the Wei-Jin period, addressing both their original writings and recent scholarly interpretations. The article aims to demonstrate that many Wei-Jin period intellectuals formed their theories through reinterpreting the relationship between texts associated with Daoism and Confucianism. Thinkers of this period often attempted to show how these defining ‘schools’ of pre-Qin Chinese thought did not propose theories that were fundamentally inconsistent, and that their ideas could be woven together as elements of a coherent view. This intellectual movement can thus be, and often has been, viewed as an attempt to integrate Daoism and Confucianism. However, a more nuanced reading demonstrates that these thinkers were reworking the relationship between what were seen as predominately Daoist or Confucian themes from their very foundation. Accordingly, the common description of Wei-Jin thinkers as ‘Daoist’ is decidedly incongruous. (shrink)
