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.
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 book is both a good introduction to Chinese philosophy and an invaluable reference tool for sinologists. Comments by important Chinese thinkers are arranged around sixty-four key concepts to illustrate their meaning and use through twenty-five centuries of Chinese philosophy. This unique guide was prepared by Zhang Dainian, one of China’s most famous living philosophers. Zhang reaches back to include concepts in use before the oracle bones —what could be called a philosophical “prehistory.” But the focus of the (...) work is those concepts that gained currency in classical Chinese philosophy, especially those whose meanings are deeper and more difficult to grasp. Translated and edited by Edmund Ryden in consultation with the author, the book also includes helpful introductory commentary by Ryden for each section. (shrink)
Wei-Bin Zhang offers an authoritative guide to the philosophy of Confucian regions, covering mainland China Taiwan, Hong Kong, Macao, Japan, South Korea, North Korea, Vietnam, and Singapore. All, except Singapore, employed Confucianism as the state ideology before the West came to East Asia. The differences and similarities between the variety of Confucian schools are examined. The author concludes that the philosophical and ethical principles of Confucianism will assist in the industrialization and democratization of the region.
Compared to constraint-based causal discovery, causal discovery based on functional causal models is able to identify the whole causal model under appropriate assumptions [Shimizu et al. 2006; Hoyer et al. 2009; Zhang and Hyvärinen 2009b]. Functional causal models represent the effect as a function of the direct causes together with an independent noise term. Examples include the linear non-Gaussian acyclic model, nonlinear additive noise model, and post-nonlinear model. Currently, there are two ways to estimate the parameters in the models: (...) dependence minimization and maximum likelihood. In this article, we show that for any acyclic functional causal model, minimizing the mutual information between the hypothetical cause and the noise term is equivalent to maximizing the data likelihood with a flexible model for the distribution of the noise term. We then focus on estimation of the PNL causal model and propose to estimate it with the warped Gaussian process with the noise modeled by the mixture of Gaussians. As a Bayesian nonparametric approach, it outperforms the previous one based on mutual information minimization with nonlinear functions represented by multilayer perceptrons; we also show that unlike the ordinary regression, estimation results of the PNL causal model are sensitive to the assumption on the noise distribution. Experimental results on both synthetic and real data support our theoretical claims. (shrink)

Inspired by Friedrich Nietzsche's idea of philology and William Gass's concept of transreading, Huiwen (Helen) Zhang employs “transreader” to suggest the integration of four roles in one: reader, translator, writer, and scholar. “Transreader” recognizes that close reading, literary translation, creative writing, and cultural hermeneutics are interdependent activities with intertwined goals: to transfer, transvalue, transform, and transcend the canon. From this perspective, Lu Xun, China's Nietzsche, is a twentieth-century transreader of the canon, and his prose poem “Revenge (The Second)” delivers (...) a self-referential ethics of transreading. Zhang's transreading of this poem shows why slow reading is today more necessary than ever, in what sense translation is a universal dilemma, how humanity grows when its expression grows more subtle, and that transreading opens a space for genuine communication.

Research on bias in peer review examines scholarly communication and funding processes to assess the epistemic and social legitimacy of the mechanisms by which knowledge communities vet and self-regulate their work. Despite vocal concerns, a closer look at the empirical and methodological limitations of research on bias raises questions about the existence and extent of many hypothesized forms of bias. In addition, the notion of bias is predicated on an implicit ideal that, once articulated, raises questions about the normative implications (...) of research on bias in peer review. This review provides a brief description of the function, history, and scope of peer review; articulates and critiques the conception of bias unifying research on bias in peer review; characterizes and examines the empirical, methodological, and normative claims of bias in peer review research; and assesses possible alternatives to the status quo. We close by identifying ways to expand conceptions and studies of bias to countenance the complexity of social interactions among actors involved directly and indirectly in peer review. (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.

This study identifies unique corporate social responsibility (CSR) dimensions and develops a framework to analyze different levels of institutional dynamics in understanding CSR in China. Based on multiple case studies of 16 firms, the article examines the CSR philosophy and approach in China's emerging market. The findings suggest that Chinese CSR understanding is largely grounded in the context of ethical and discretionary actions. This focus is mainly attributed to the dominant role of ethical leadership, governmental dependency, and cultural traditions in (...) Chinese CSR. Moreover, the weakness or the absence of conducive social normative environment and positive peer pressure, and misalignment between CSR and organizational design further contribute to a lack of systemic and institutionalized approach to CSR in China. Our study implies that CSR is still evolving at a preliminary stage in China, and institutional infrastructure and cultural ethics are exerting abiding influence on CSR approach in the emerging economies. The article also suggests the implications for practice and policy making. (shrink)
Prior research suggests that ownership structure is associated to corporate social responsibility (CSR) in developed countries. This article examines whether and how ownership structure affects CSR in emerging markets using Chinese firms' social responsibility ranking. Our empirical evidences show that for non-state-owned firms, corporate ownership dispersion is positively associated to CSR. However, for state-owned firms, whose controlling shareholder is the state, this relation is reversed. We attribute the reversed relationship to political interferences and further test this hypothesis by demonstrating that (...) regional economic development is negatively related to CSR for state-owned firms due to decreased political interference in more developed areas. This study is the first to directly examine the relationship between the dispersion of corporate ownership and CSR in emerging markets, and our results depict that it is important to consider ownership type in assessing CSR in emerging market where state ownership is still prevalent such as China. The results also reveal that firm size, profitability, employee power, leverage, and growth opportunity affect CSR in China. (shrink)
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)
Drawing on risk mitigation theory, this article examines whether the improvement of firms’ social performance reduces debt financing costs (CDFs) in China, the world’s largest emerging market. Employing both the ordinary least square (OLS) and the two-stage instrumental variable regression methods, we find that improved corporate social responsibility (CSR) reduces the CDF when firms’ CSR investment is lower than an optimal level; however, this relationship is reversed after the CSR investment exceeds the optimal level. Firms with extremely low or extremely (...) high CSR are subject to a higher CDF. The results also suggest that the optimal CSR level for small firms is higher than that for large firms. This study is the first to document a U-shaped relationship between CSR and CDF and also the first to investigate this relationship within an emerging market context. (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)
