In order to further improve the complexity of chaotic system, a new four-dimensional chaotic system is constructed based on Sprott B chaotic system. By analyzing the system’s phase diagrams, symmetry, equilibrium points, and Lyapunov exponents, it is found that the system can generate not only both two-wing and four-wing attractors but also the attractors with symmetrical coexistence, and the dynamic characteristics of the new system constructed are more abundant. In addition, the system is simulated by Multisim software, and the simulation (...) results show that the results of circuit simulation and numerical simulation analysis are basically the same.

In this paper, a new 4D memristor-based chaotic system is constructed by using a smooth flux-controlled memristor to replace a resistor in the realization circuit of a 3D chaotic system. Compared with general chaotic systems, the chaotic system can generate coexisting infinitely many attractors. The proposed chaotic system not only possesses heterogeneous multistability but also possesses homogenous multistability. When the parameters of system are fixed, the chaotic system only generates two kinds of chaotic attractors with different positions in a very (...) large range of initial values. Different from other chaotic systems with continuous bifurcation diagrams, this system has discrete bifurcation diagrams when the initial values change. In addition, this paper reveals the relationship between the symmetry of coexisting attractors and the symmetry of initial values in the system. The dynamic behaviors of the new system are analyzed by equilibrium point and stability, bifurcation diagrams, Lyapunov exponents, and phase orbit diagrams. Finally, the chaotic attractors are captured through circuit simulation, which verifies numerical simulation. (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.

The panel was sponsored by the APA’s “Committee on Asian and Asian-American Philosophers and Philosophies” and organized by Brian Bruya.
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)
Based on a crowdsourced truth value judgment experiment, we provide empirical evidence challenging two classical views in semantics, and we develop a novel account of counterfactuals that combines ideas from inquisitive semantics and causal reasoning. First, we show that two truth-conditionally equivalent clauses can make different semantic contributions when embedded in a counterfactual antecedent. Assuming compositionality, this means that the meaning of these clauses is not fully determined by their truth conditions. This finding has a clear explanation in inquisitive semantics: (...) truth-conditionally equivalent clauses may be associated with different propositional alternatives, each of which counts as a separate counterfactual assumption. Second, we show that our results contradict the common idea that the interpretation of a counterfactual involves minimizing change with respect to the actual state of affairs. We propose to replace the idea of minimal change by a distinction between foreground and background for a given counterfactual assumption: the background is held fixed in the counterfactual situation, while the foreground can be varied without any minimality constraint.

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 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)
Responding to the paradox of inference and the related problems in philosophy of logic, this paper argues for the necessity of distinguishing between two different objects of justification: logica utens and logica docens. Then, equipped with Peirce’s critical common-sensist conception of logica utens and his classification of sciences, I propose a diagnosis of and a solution to the problem of justification of logic. I argue that this alternative approach successfully avoids circularity in which most attempts in philosophy of logic have (...) been inescapably trapped. I also anticipate and respond to possible objections to taking a Peircean turn in justifying logic. (shrink)
Zhang Junmai (Carsun Chang, 1877-1969) Zhang Junmai (Chang Chun-mai, 1877-1969), also known as Carsun Chang, was an important twentieth-century Chinese thinker and a representative of modern Chinese philosophy.

BackgroundExercise self-efficacy is a vital determinant of an individual’s active participation in regular exercise, and exercise is a critical component of improving health-related quality of life in dialysis patients. This study aimed to describe the relationship between exercise self-efficacy and HRQOL in dialysis patients.Materials and MethodsA cross-sectional study was conducted in Shanghai, China. Structured questionnaires distributed to the patients collected socio-demographic and disease-related information. Physical activity was assessed by a self-administered questionnaire, and the exercise self-efficacy scale was used to measure (...) exercise self-efficacy. HRQOL was evaluated by the kidney disease quality of life instrument-short form version 1.3. Data were analyzed using a univariate generalized linear model, Spearman correlation, and hierarchical multiple regression.ResultsA positive association was observed between exercise self-efficacy and HRQOL. Physical activity as a predictor variable explained 9.8% of the variance in overall HRQOL. Exercise self-efficacy explained an additional 7.1% of the HRQOL variance. In total, 24.6% of the variation in the HRQOL was explained by the socio-demographic variables, disease-related factors, physical activity, and exercise self-efficacy.ConclusionOverall, only 16.9% of the change in HRQOL was explained by physical activity and exercise self-efficacy. Future research is still needed to further explore the factors influencing the HRQOL in dialysis patients. However, this finding suggests the need to consider the importance of HRQOL and physical activity as well as exercise self-efficacy when developing intervention programs. (shrink)
This book analyzes the ways in which authoritarian political culture performs functions similar to democratic political culture, using contemporary Chinese politics as a case study. Through an examination of the legitimating and engaging values of Confucianism, the author analyzes how these values influence everyday political engagement, perceptions and practices of “rule of law,” political deliberation, and official discourse of the Chinese Communist Party.
It is well-acknowledged that teachers play a significant role in enhancing student learning and that investigating teachers’ cognitions about teaching is a first and important step to understanding the phenomenon. Although much research into teachers’ cognitions about grammar teaching has been conducted in various socio-cultural contexts, little has been reported on cognitions of Chinese teachers of English as a foreign language so far. Such understanding is of primary importance to student success in language learning given the sociocultural context where grammar (...) takes a lion’s share in high-stakes examinations. In order to address this research gap, we developed and validated the Chinese EFL Teachers’ Cognitions about Grammar Teaching Questionnaire. Two subsamples were randomly invited to respond to the TCAGTQ and the data were then subjected to exploratory factor analysis and confirmatory factor analysis to test the validity and reliability of the instrument. The EFA excluded eight items from the TCAGTQ and generated six factors with 27 items. The CFA result from the other subsample supported a six-factor model with a good model fit. Moderate correlations between the six factors also supported the predictive validity of the questionnaire, showing that the TCAGTQ is a valid and reliable inventory for measuring Chinese university EFL teachers’ cognitions about grammar teaching. Our findings suggest that the TCAGTQ can be used as a useful tool for teachers to self-assess their professional practice for improving teaching. (shrink)
Qi is one of the most important concepts in Chinese philosophy and culture, and neo-Confucian Zhang Zai plays a pivotal role in developing the notion. This book provides a thorough and proper understanding of his thoughts.
This essay initiates elements of a Daoist stance as regards the basic assumptions and principles involved in debates on multiculturalism. This is to be achieved via an examination of Zhang Taiyan’s 章太炎 mid-term political philosophy, which is shaped by his interpretation and further development of Daoist thinking, especially the notion of no-thing and the idea of “achieving equality by leaving things uneven”. After explicating the basic tenets that point toward a Daoist stance on what is now called multiculturalism, I (...) discuss Zhang’s concrete proposals concerning the relation between the Han 漢 lineage and the other four major ethnic groups in the to-be-established Republic of China. I then investigate Zhang’s unique theory of the state. Lastly, I explore the discordance in Zhang Taiyan’s thinking despite his privileging of Laozi 老子 and Zhuangzi’s 莊子 ideas. (shrink)
The rapidly growing data in many areas, as well as in the biomedical domain, require the assistance of information extraction systems to acquire the much needed knowledge about specific entities such as proteins, drugs, or diseases practically within a short time. Annotated corpora serve the purpose of facilitating the process of building NLP systems. While colossal work has been done in this area for English language, other languages like Arabic seem to lack these resources, especially in the healthcare area. Therefore, (...) in this work, we present a method to develop a silver standard medical corpus for the Arabic language with a dictionary as a minimal supervision tool. The corpus contains 49,856 sentences tagged with 13 entity types corresponding to a subset of UMLS concept types. The evaluation of a subset of corpus showed the efficiency of the method used to annotate it with 90% accuracy. (shrink)
More than half a century ago, a so-called Third Side appeared in China's political arena. The word "third" signified that its proponents intended to take a "middle way" amid the desperate, life-and-death battle between the Nationalist party and the Communist party. In a 1946 speech delivered at the Tianjin YMCA, entitled "A Political Line of an Intermediate Nature," Zhang Dongsun presented a clear and to-the-point formulation of this "middle way":In the political aspect, we should adopt more from the British (...) and American type of liberalism and democracy, while at the same time adopting, in the economic aspect, more from the Soviet Union's type of planned economy and socialism. From the negative aspect, we should adopt democracy but not capitalism. We should also adopt socialism but not the revolution of proletarian dictatorship. We want freedom but not an everything-goes attitude. We want cooperation but not struggle. Since we do not want an everything-goes attitude, we do not want monopolies by capitalists. Since we do not want struggle, we do not want class struggle. (shrink)
BackgroundPostgraduates usually face more life challenges than undergraduate students, including social, emotional and financial issues, and the prevalence of mental health problems in postgraduates is higher than undergraduates. Therefore, the attention on postgraduates’ mental health status is needed.ObjectivesThe current study explored the relationship between postgraduates’ emotional intelligence and well-being by investigating the mediating effects of social support and psychological resilience and the relationship between them through the construction of a chain mediation model.Method1,228 postgraduates completed the Emotional Intelligence Scale, the Social (...) Support Rate Scale, the Psychological Resilience Scale, and the Subject Well-being Scale.ResultsThere is a chain effect between postgraduates’ social support and psychological resilience mediated by their emotional intelligence and well-being, with a total effect value of 0.049.ConclusionEmotional intelligence has a predictive effect on postgraduates’ well-being. The mechanism of this effect includes the indirect effects of social support and psychological resilience. Study results revealed the relationship mechanism between emotional intelligence and postgraduates’ well-being, and provide reference for explorations of how to development postgraduates’ emotional intelligence and further improving their abilities to strengthen their emotional resilience.

An extensive work has been done on corporate social responsibly practices that mainly emphasized the larger firms within developed nations. Nonetheless, still work is needed to observe the importance of CSRPs’ and ethical cultural practices in terms of sustainable competitive performance that garnered far less attention by the existing literature. This study explores the impact of CSRPs on SACP with the mediating role of ECL from SMEs of two emerging nations, i.e., China and Pakistan based on stakeholders’ theory and practices. (...) The results using SEM affirmed the positive linkages of CSRPs—environment responsibility, community responsibility, customers' responsibility, suppliers responsibility, employee responsibility, and Govt. rules & regulations’ responsibility —on SACP. It found that CSRPs have positive relationships with ECL whereas ECL further positively correlated with SACP in the context of both countries. The findings revealed the positive mediating influence of ECL between CSRPs and SACP, respectively. This study furnishes insightful information for management on how firms may achieve sustainable performance by incorporating ethical cultural practices and corporate social responsibility practices as the strategic tools. The study reports numerous implications for management together with lines for future directions. (shrink)
The economic and cultural effects of sports films have attracted close attention from academia as well as the industry. In this paper, two sub-studies were conducted to explore the empathy mechanism performance of the interest-related community in sports films. In Study 1, the film Lead was applied as an example and used network text analysis to analyze the discourse characteristics and structure of its interest-related community to grasp the practice regularities. More specifically, the results in Study 1 show that the (...) theme feature, brand building, technological innovation, and spirit communication are the key factors that affect an individual's empathy for sports films. In Study 2, I conducted a survey to explore the empathy mechanism of sports films in the new age to provide a theoretical reference for the high-quality development of films. The above-mentioned four main factors have positive impacts on empathy: affective empathy and cognitive empathy. (shrink)
Based on the analysis of the organic geochemical characteristics of the shale in the Da’anzhai Member in the Sichuan Basin, southwest China, we discuss the hydrocarbon generation potential, hydrocarbon expulsion efficiency, and oil-bearing properties to identify the dominant exploration direction for shale oil. The results indicate that: the Da’anzhai shale has low organic matter content and high maturity with the average total organic carbon content of 1.27% and average vitrinite reflectance of 1.29%, the EH of the Da’anzhai shale ranges from (...) 0% to 92% with an average value of 72%, the lower limit of TOC for shale commercial production is 1.5%, which is lower than any current standard in China and North America, and shale oil in the center lacustrine basin is more enriched compared with the outskirts of the basin with [Formula: see text], Ro 100 mg/. These results indicate that the prospects for shale oil exploration in the central basin are optimistic and should be the key exploration area for shale oil in the future. (shrink)
: Studies of Chinese dialectical materialism have long neglected the important philosophical dimension of Hegelian thought and its influence on Chinese Marxism. This essay examines the work of Zhang Shiying of Beijing University, whose studies of Hegel's works on dialectical logic in the 1950s sought to clarify the nature of Hegel's speculative dialectic and its relation to dialectical materialism. Like Lenin before him, Zhang believed that Hegel's works on logic offered a more profound reflection on materialism than had (...) previously been recognized by Marxist critics of German idealism. Zhang's sensitive reading of both Hegel's Science of Logic and the Encyclopedia Logic highlights the problem of the speculative dialectic and negativity. Examined here is Zhang's analysis of the Hegelian dialectic in light of contemporary accounts of the role of Hegelian negativity in poststructuralist thought. (shrink)

Jeffrey conditionalization is a rule for updating degrees of belief in light of uncertain evidence. It is usually assumed that the partitions involved in Jeffrey conditionalization are finite and only contain positive-credence elements. But there are interesting examples, involving continuous quantities, in which this is not the case. Q1 Can Jeffrey conditionalization be generalized to accommodate continuous cases? Meanwhile, several authors, such as Kenny Easwaran and Michael Rescorla, have been interested in Kolmogorov’s theory of regular conditional distributions as a possible (...) framework for conditional probability which handles probability-zero events. However the theory faces a major shortcoming: it seems messy and ad hoc. Q2 Is there some axiomatic theory which would justify and constrain the use of rcds, thus serving as a possible foundation for conditional probability? These two questions appear unrelated, but they are not, and this paper answers both. We show that when one appropriately generalizes Jeffrey conditionalization as in Q1, one obtains a framework which necessitates the use of rcds. It is then a short step to develop a general theory which addresses Q2, which we call the theory of extensions. The theory is a formal model of conditioning which recovers Bayesian conditionalization, Jeffrey conditionalization, and conditionalization via rcds as special cases. (shrink)
Early and later Confucians, known in Chinese as the “ruists” school of ancient origins, perceived the idea of “harmony” as a fundamental concept that lies at the basis of self-cultivation, society and governance. In modern times this idea still plays in one or another form a dominant note in Chinese politics and social life. The article attempts to search for causes of the significance of “harmony” by focusing on analyzing two pivotal Confucian texts compiled in the Han dynasty, namely, Records (...) of Music [Yue ji 樂記] and Divination of Music [Yue wei 樂緯]. The analysis shows that ruists belonging to Zhou dynasty’s imperial class of music officials, gradually developed the aesthetics of music into a complex idea of "harmony" that contains the highest aesthetical way—“Dao”—which guides both the whole universe as well as the evolution of human society.
