Fractures and fracture-related dissolution pores, as well as cavities, molds, and vugs, provide the major conduit and/or storage space for hydrocarbons in the deeply buried carbonate hill of Hexiwu field, Bohai Bay Basin. The fractured reservoir generally has lower porosity but better permeability than moldic/vuggy reservoir, and it consists of the major part of the buried-hill slope and buried-hill internal reservoirs. The conventional method of characterizing carbonate reservoirs, however, often mixes these two types of reservoirs together because they both have (...) low acoustic impedance and low bulk modulus. The rock-physics analysis of two field wells indicates that a pore-structure parameter defined in a rock-physics model, the so-called Sun model, can help to distinguish the fractured reservoir zones together with porosity. Fractured zones usually have porosity of less than 5% and a pore-structure parameter of greater than six, whereas moldic/vuggy reservoirs of higher porosity have a pore-structure parameter of less than six. Field-scale application demonstrates that simultaneous prestack seismic inversion for the porosity and pore-structure parameter enables 3D mapping of fractured reservoir zones in the buried carbonate hills. It also provides an analog of detecting fractures and/or fracture-related pores in deeply buried carbonates in similar geologic settings. (shrink)

We have integrated core, well logs, and seismic data to analyze fluvial types and reconstruct sediment dispersal patterns of the Dongying Formation in the Wen’an Slope, Bohai Bay Basin. We analyzed four meandering-braided fluvial successions from the Dongying Formation in the Wen’an Slope. The results indicate that the fluvial systems are dominantly northeast–southwest and consist of channel, channel bar, and flood plain subfacies, which can be further subdivided into six microfacies including braided channel, meandering channel, sandy channel bar, muddy channel (...) bar, crevasse fan, and floodplain. With a paleoflow direction, [Formula: see text] ranges from 40° to 65°, the river belt width [Formula: see text] is estimated to be 1.47–2.64 km, whereas the main channel width varies from 0.02 to 0.29 km and its thickness/bankfull depth [Formula: see text] ranges from 1.2 to 6.4 m. The differential subsidence of rift basin during fault-depression transition period is the main control on fluvial evolution and sand body distribution. The climatic effect causes changes in river flow. During the flood season, river flow and flow rate are large, and early sediments and sand bodies are reconstructed. Lateral erosion and undercutting are very strong in this period. In the dry season, the river is dominated by weak lateral erosion. Our study also suggests that the development of thick mudstone in the upslope may limit hydrocarbon charging and migration and thick channel and channel bar deposits in the middle and downslope cross cut by faults, which are conduits for migration are likely to be the most potential reservoirs in the Bohai Bay Basin.

This article assumes that a profession is a number of individuals in the same occupation voluntarily organized to earn a living by openly serving a moral ideal in a morally-permissible way beyond what law, market, morality, and public opinion would otherwise require. Our question is whether the concept of profession may have a far wider range than the term, so that, for example, pointing out that a certain language lacks a word for “profession” in our sense, is not enough to (...) show that those who speak the language also lack the concept. We believe the survey of 71 Chinese reported here begins to answer that question. This article has four parts. The first describes who was interviewed, how, when, and so on. The second describes some important features of the survey’s questions, explaining how the questions track the concept of profession. The third part reports and interprets the results relevant to our question. The forth defends a tentative answer to the question with which we began—arguing the survey supports the claim that China has a profession of engineering. This article should serve as a “proof of concept”, that is, a model for similar studies around the world both of engineering and of other occupations thought to be professions. (shrink)

For the West … China as a land in the Far East becomes traditionally the image of the ultimate Other. What Foucault does in his writing is, of course, not so much to endorse this image as to show, in the light of the Other, how knowledge is always conditioned in a certain system, and how difficult it is to get out of the confinement of the historical a priori, the epistemes or the fundamental codes of Western culture. And yet (...) he takes the Borges passage seriously and remarks on its apparent incongruity with what is usually conceived about China in the Western tradition. If we are to find any modification of the traditional image of China in Foucault’s thought, it is then the association of China not with an ordered space but with a space without any conceivable arrangement or coherence, a space that makes any logical ordering utterly unthinkable. Significantly, Foucault does not give so much as a hint to suggest that the hilarious passage from that “Chinese encyclopaedia” may have been made up to represent a Western fantasy of the Other, and that the illogical way of sorting out animals in that passage an be as alien to the Chinese mind as it is to the Western mind.In fact, the monstrous unreason and its alarming subversion of Western thinking, the unfamiliar and alien space of China as the image of the Other threatening to break up ordered surfaces and logical categories, all turn out to be, in the most literal sense, a Western fiction. Nevertheless, that fiction serves a purpose in Foucault’s thought, namely, the necessity of setting up a framework for his archaeology of knowledge, enabling him to differentiate the self from what is alien and pertaining to the Other and to map out the contours of Western culture recognizable as a self-contained system. Indeed, what can be a better sign of the Other than a fictionalized space of China? What can furnish the West with a better reservoir for its dreams, fantasies, and utopias?

For repeatable motion of redundant mobile manipulators, the flexible base platform and the redundant manipulator have to be returned to the desired initial position simultaneously after completing the given tasks. To remedy deviations between initial position and desired position of each kinematic joint angle, a special kind of repeatable optimization for kinematic energy minimization based on terminal-time Zhang neural network with finite-time convergence is proposed for inverse kinematics of mobile manipulators. It takes the advantages that each joint of the (...) manipulator is required to return to the desired initial position not considering the initial orientation of itself for realizing repeatable kinematics control. Unlike the existed training methods, such an optimization of kinematic energy scheme based on TTZNN can not only reduce the convergent position error of each joint to zero in finite time, but also improve the convergent precision. Theoretical analysis and verifications show that the proposed optimal kinematic energy scheme accelerates the convergent rate, which is tended to be applied in practical robot kinematics. Simulation results on the manipulator with three mobile wheels substantiate the timeliness and repetitiveness of the proposed optimization scheme. (shrink)

This article examines whether the likelihood and amount of firm charitable giving in response to catastrophic events are related to firm advertising intensity, and whether industry competition level moderates this relationship. Using data on Chinese firms’ philanthropic response to the 2008 Sichuan earthquake, we find that firm advertising intensity is positively associated with both the probability and the amount of corporate giving. The results also indicate that this positive advertising intensity-philanthropic giving relationship is stronger in competitive industries, and firms in (...) competitive industries are more likely to donate. This study thus provides evidence suggesting that even in the wake of catastrophic events, corporate philanthropic giving is strategic. (shrink)

Recent studies of organizational behavior have witnessed a growing interest in unethical leadership, leading to the development of abusive supervision research. Given the increasing interest in the causes of abusive supervision, this study proposes an organizing framework for its antecedents and tests it using meta analysis. Based on an analysis of effect sizes drawn from 74 studies, comprising 30,063 participants, the relationship between abusive supervision and different antecedent categories are examined. The results generally support expected relationships across the four categories (...) of abusive antecedents, including: supervisor related antecedents, organization related antecedents, subordinate related antecedents, and demographic characteristics of both supervisors and subordinates. In addition, possible moderators that can also influence the relationships between abusive supervision and its antecedents are also examined. The significance and implications of different level factors in explaining abusive supervision are discussed. (shrink)

Although the composition of the board of directors has important implications for different aspects of firm performance, prior studies tend to focus on financial performance. The effects of board composition on corporate social responsibility (CSR) performance remain an under-researched area, particularly in the period following the enactment of the Sarbanes-Oxley Act of 2002 (SOX). This article specifically examines two important aspects of board composition (i.e., the presence of outside directors and the presence of women directors) and their relationship with CSR (...) performance in the Post-SOX era. With data covering over 500 of the largest companies listed on the U.S. stock exchanges and spanning 64 different industries, we find empirical evidence showing that greater presence of outside and women directors is linked to better CSR performance within a firm’s industry. Treating CSR performance as the reflection of a firm’s moral legitimacy, our study suggests that deliberate structuring of corporate boards may be an effective approach to enhance a firm’s moral legitimacy.

Much of the recent work on the epistemology of causation has centered on two assumptions, known as the Causal Markov Condition and the Causal Faithfulness Condition. Philosophical discussions of the latter condition have exhibited situations in which it is likely to fail. This paper studies the Causal Faithfulness Condition as a conjunction of weaker conditions. We show that some of the weaker conjuncts can be empirically tested, and hence do not have to be assumed a priori. Our results lead to (...) two methodologically significant observations: (1) some common types of counterexamples to the Faithfulness condition constitute objections only to the empirically testable part of the condition; and (2) some common defenses of the Faithfulness condition do not provide justification or evidence for the testable parts of the condition. It is thus worthwhile to study the possibility of reliable causal inference under weaker Faithfulness conditions. As it turns out, the modification needed to make standard procedures work under a weaker version of the Faithfulness condition also has the practical effect of making them more robust when the standard Faithfulness condition actually holds. This, we argue, is related to the possibility of controlling error probabilities with finite sample size (“uniform consistency”) in causal inference. (shrink)

This article examines whether the charitable giving amount and likelihood of firm response to catastrophic events relate to firms' ownership type using a unique dataset of listed firms in China, where state ownership is still prevalent. Based on the data of Chinese firms' response to the 2008 Sichuan earthquake, we find that the extent of corporate contributions for state-owned firms following this disaster is less than that for private firms. State-owned firms are also less likely to respond in this disaster (...) compared to private firms. The results also reveal that firm size, profitability, geography, cash resource available, and leverage affect firms' philanthropic disaster response behavior in China. (shrink)

The main considerations for well planning and hydraulic fracturing in unconventional resources plays include the amount of total organic carbon and how much hydrocarbon can be extracted. Brittleness is the direct measurement of a formation about the ability to create avenues for hydrocarbons when applying hydraulic fracturing. Brittleness can be directly estimated from laboratory stress-strain measurements, rock-elastic properties, and mineral content analysis using petrophysical analysis on well logs. However, the estimated brittleness using these methods only provides “cylinder” estimates near the (...) borehole. We proposed a workflow to estimate brittleness of resource plays in 3D by integrating the petrophysics and seismic data analysis. The workflow began by brittleness evaluation using mineral well logs at the borehole location. Then, we used a proximal support vector machine algorithm to construct a classification pattern between rock-elastic properties and brittleness for the selected benchmark well. The pattern was validated using well-log data that were not used for constructing the classification. Next, we prestack inverted the fidelity preserved seismic gathers to generate a suite of rock-elastic properties volumes. Finally, we obtained a satisfactory brittleness index of target formations by applying the trained classification pattern to the inverted rock-elastic-property volumes. (shrink)

In this paper, a finance system with delay is considered. By analyzing the corresponding characteristic equations, the local stability of equilibrium is established. The existence of Hopf bifurcations at the equilibrium is also discussed. Furthermore, formulas for determining the direction of Hopf bifurcation and the stability of the bifurcating periodic solutions are derived by applying the normal form method and center manifold theorem. Finally, numerical simulation results are presented to validate the theoretical analysis. Numerical simulation results show that delay can (...) lead a stable system into a chaotic state. (shrink)

Variable stiffness actuator is a new actuation of robot which is inspired by motor control of human arm. And it is promising way to exploit the human-like performance and human-like motion. However, due to the mechanical complexity and redundancy of the actuators, it is not trivial to control the variable stiffness actuated robot to perform a human-like motion. In this paper, the weight lifting problem with variable stiffness actuated robot is studied. Then, the original problem is formulated as a constrained (...) optimal control problem and transformed as a general nonlinear programming problem with Gauss pseudospectral method. Simulation studies demonstrate the effectiveness of the proposed method compared with the iLQR approach. Furthermore, the simulations results are presented to show the influence of stiffness variation of variable stiffness actuators on the weight lifting problem. (shrink)

Modern socialist economic reforms which center on the establishment of a commodity based economic system, demand a reconsideration of human nature. Marxism and human sociobiology give different answers to questions about human nature, but neither is complete in itself. It seems timely, therefore, to suggest that a combination of biological understanding with a Marxist-based social understanding would produce a more adequate notion of human nature, thereby helping us to resolve a number of problems posed by reforms currently taking place in (...) socialist countries. We might also hope to face new challenges posed in the future. (shrink)

In this study, an accurate convergence time of the supertwisting algorithm is proposed to build up a framework for nonaffine nonlinear systems’ finite-time control. The convergence time of the STA is provided by calculating the solution of a differential equation instead of constructing Lyapunov function. Therefore, precise convergence time is presented instead of estimation of the upper bound of the algorithm’s reaching time. Regardless of affine or nonaffine nonlinear systems, supertwisting control provides a general solution based on virtual control law (...) skill ensuring the output of the systems converges to the origin point at exact time. Benchmark tests are simulated to demonstrate the effectiveness and efficiency of the algorithm. (shrink)

In response to the lack of empirical studies examining the internal disclosure behavior in the Chinese context, this study tested a whistleblowing -decision-making process among employees in the Chinese banking industry. For would-be whistleblowers, positive affect and organizational ethical culture were hypothesized to enhance the expected efficacy of their whistleblowing intention, by providing collective norms concerning legitimate, management-sanctioned behavior. Questionnaire surveys were collected from 364 employees in 10 banks in the Hangzhou City, China. By and large, the findings supported the (...) hypotheses. Issues of whistleblowing in the Chinese context and implications were discussed. (shrink)

Forty-six core samples were collected from a deep well that penetrated organic-rich layers of the Chang 7, 8, and 9 members of the Yanchang Formation in the Ordos Basin. Tests for total organic content, Rock-Eval pyrolysis, X-ray diffraction mineralogy, and molecular composition of gases released from rock crushing were conducted. Analytical results indicate that TOC and clay contents are elevated. The organic matter -rich mudstone in the Triassic Yanchang Fm suggests good-to-excellent source potential for oil generation. Its thermal maturity is (...) in the oil window. Strong petroleum expulsion occurred from the upper part of the approximately 13 m thick Chang 7 member, and for the Chang 8 and Chang 9 members, resulting in low free oil and low methane concentration in these OM-rich intervals. A combination of sandstone and thin organic-rich mudstone layers is a perfect hybrid lithology stacking pattern for petroleum expulsion. The thickness for effective source rock, approximately 10–12 m, varied with sandstone/mudstone lithology stacking pattern. In contrast, limited or no oil expulsion occurred in the lower part of Chang 7 member, a 25 m thick organic-rich interval, which is indicated by high free oil and high [Formula: see text] concentration. A [Formula: see text]-TOC plot can be used to differentiate generated gas, retained gas in OM-rich mudstones, and migrated gas in permeable sandstone beds. We have developed a conceptual model for petroleum expulsion from OM-rich thin versus OM-rich thick layers. Compaction and thermal volume expansion of oil generated from OM may play an important role in petroleum expulsion in OM-rich mudstones. The estimated petroleum expulsion efficiency is approximately 70% and 35% for thin and thick OM-rich mudstone layers, respectively. The redistributed OM in clay-dominated rock assemblage likely forms the preferred migration path to petroleum expulsion. (shrink)

Guanxi in China is a very ancient concept embedded in the Confucian concept of life and one that is a ‚hot' topic in that it is currently attracting increasing attention from both Western and Chinese scholars. One aspect of Guanxi which has been the subject of most of the research of late is the influence of Guanxi on firm performance. However, relatively few studies have examined how Guanxi at the individual level is transferred into a firm to influence its financial (...) performance. This study first reclassifies Guanxi into obligatory, reciprocal, and utilitarian types at the individual level as a means to clarifying the confusion brought above from previous studies. It then provides a conceptual framework in which to systematically characterize the link between Guanxi at the individual level and organizational dynamics: that is, how is Guanxi at the individual level shifted to a firm and how does it affect organizational dynamics of that firm at the organizational level. Finally, it provides a deeper understanding of the financial implications of Guanxi to business firms in China. (shrink)

This article describes a representation-based framework of distributed cognition. This framework considers distributed cognition as a cognitive system whose structures and processes are distributed between internal and external representations, across a group of individuals, and across space and time. The major issue for distributed research, under this framework, are the distribution, transformation, and propagation of information across the components of the distributed cognitive system and how they affect the performance of the system as a whole. To demonstrate the value of (...) this representation-based approach, the framework was used to describe and explain an important, challenging, and controversial issue — the concept of affordance.

Business Ethics: A European Review, EarlyView.

The framework of causal Bayes nets, currently influential in several scientific disciplines, provides a rich formalism to study the connection between causality and probability from an epistemological perspective. This article compares three assumptions in the literature that seem to constrain the connection between causality and probability in the style of Occam's razor. The trio includes two minimality assumptions—one formulated by Spirtes, Glymour, and Scheines (SGS) and the other due to Pearl—and the more well-known faithfulness or stability assumption. In terms of (...) logical strength, it is fairly obvious that the three form a sequence of increasingly stronger assumptions. The focus of this article, however, is to investigate the nature of their relative strength. The comparative analysis reveals an important sense in which Pearl's minimality assumption is as strong as the faithfulness assumption and identifies a useful condition under which it is as safe as SGS's relatively secure minimality assumption. Both findings have notable implications for the theory and practice of causal inference. 1 Introduction2 Background: Inference of Causal Structure in Markovian Causal Models3 Three Assumptions of Simplicity4 A Comparison of P-minimality and Faithfulness5 A Comparison of P-minimality and SGS-minimality6 Methodological Formulations and Prior Knowledge of Causal Order7 Conclusion.

Universal Bundle Theory holds that objects are fundamentally identical with bundles of universals. Universals are multiply instantiable properties. One popular objection to UBT concerns the possibility of distinct indiscernibles. There are mainly two replies in the literature, corresponding to two representative UBTs, which I shall call the Identity-View and the Instance-View. Each view faces serious problems. This paper proposes a new version of UBT and argues that it is better than these other two versions.

In the causal inference framework of Spirtes, Glymour, and Scheines, inferences about causal relationships are made from samples from probability distributions and a number of assumptions relating causal relations to probability distributions. The most controversial of these assumptions is the Causal Faithfulness Assumption, which roughly states that if a conditional independence statement is true of a probability distribution generated by a causal structure, it is entailed by the causal structure and not just for particular parameter values. In this paper we (...) show that the addition of the Causal Faithfulness Assumption plays three quite different roles in the SGS framework: it reduces the degree of underdetermination of causal structure by probability distribution; computationally, it justifies reliable causal inference algorithms that would otherwise have to be slower in order to be reliable; and statistically, it implies that those algorithms reliably obtain the correct answer at smaller sample sizes than would otherwise be the case. We also consider a number of variations on the Causal Faithfulness Assumption, and show how they affect each of these three roles. (shrink)

High-performance work systems -performance research has dominated innovative human resource management studies for two decades. However, mainstream HPWS research has paid little attention to employees’ perceptions of HPWS, or to the relationship between HPWS and corporate social performance. The influence of CSP on employee outcomes such as organizational commitment and organizational citizenship behaviour has thus been similarly neglected. This paper seeks to investigate these missing links in literature using data collected from a sample of 700 employees in China. The findings (...) demonstrate that HPWS is positively related to HPWS satisfaction and employees’ perceptions of CSP. HPWS satisfaction fully mediates the relationship between HPWS and employees’ affective commitment. There are multiple mediators between HPWS and OCB, indicating more complicated mechanisms through which HPWS leads to desired HR outcomes. Employees’ perceived CSP has a significant influence on HPWS satisfaction, AC and OCB, suggesting firms should place a premium on achieving a reputation as being socially responsible. (shrink)

Scientists normally earn less money than many other professions which require a similar amount of training and qualification. The economic theory of marginal utility and cost-benefit analysis can be applied to explain this phenomenon. Although scientists make less money than entertainment stars, the scientists do research work out of their interest and they also enjoy a much higher reputation and social status in some countries.
