In this paper, a repetitive control scheme of a 2-DOF robotic manipulator based on the improved cubic B-spline curve is proposed. Firstly, a repetitive controller for robotic manipulator is designed, which is composed of an iterative controller and disturbance observer. Then, an improved B-spline optimization scheme is introduced to divide the task of the robotic manipulator into three intervals. A correction function is added to each interval of cubic spline interpolation. Finally, a variety of cases are designed and simulated by (...) MATLAB. The experimental results show that, compared with the conventional B-spline, the improved B-spline has better performance in tracking accuracy and smoothness of motion trajectory. By changing the mechanism of the manipulator, the cases of different weights and lengths are designed. The experimental results in these cases show that the proposed scheme can be applied to most of the 2-DOF robotic manipulator control systems. (shrink)

This empirical research provides an insight into the management of small talk and its interconnection with interpersonal relations in business negotiations, drawing on the study of its pragmatic allocation, modes and functions in business contexts. By examining ST applications in three interpersonal relationships, the author explores how the interactional patterns of ST are associated with communicators’ interpersonal cognitive processes, demonstrating why ST should not be deemed ‘small’ in task-oriented contexts. The findings yield that ST constructs an integral, and even essential, (...) part of business communication for various social and professional purposes. Its allocations, topic typologies and move systems in negotiations are not randomly positioned, selected and developed, but strategically organized and interpersonally related. As a meaningful, politic and intentional activity, ST reflects business people’s social and professional cognition, relational negotiation and interactive frame, forming communicative primitives that are used in the underlying negotiation, the rapport management in negotiation and cultural disciplines for business people.

While the conversations surrounding moral cultivation in Confucianism often focus on the debate regarding the starting point of moral learning (and corresponding features of the learning process) that is inspired by the disagreements between the _Mengzi_ 孟子 and the _Xunzi_ 荀子, there is another group of scholarship on moral cultivation which tends to the experiential qualities felt by the learning agents. This essay participates in the latter group of scholarship. The majority of discussions regarding the learning experience center around mental (...) states such as _an_ 安 (tranquility or equanimity) and _le_ 樂 (happiness, joy, or pleasure) of a special kind. There is, nonetheless, a minor trend that emphasizes the significance of _you_ 憂 (worry or distress). In this essay, I raise attention to the significance of _you_ and argue that in the _Analects_, an indispensable and significant part of Confucian moral cultivation is to learn to worry well, which involves learning to worry broadly about society in general, and to worry deeply about particular individuals standing in important relationship to us_._.

Work procrastination is a retreat behavior associated with negative cognitive experience and it results in great losses to individual as well as organizational development. Understanding the antecedents of employees’ work procrastination behavior contributes to lower frequency of its occurrence. This research builds a dual-moderated mediation model from the perspective of cognitive appraisal theory and explored work procrastination behavior of employees subjected to abusive supervision. With 378 valid returned questionnaires, data collected from 32 companies in Beijing, Shanghai, Tianjin, and Chongqing supports (...) our hypotheses. This result has enriched the understanding of work procrastination behavior and provided practical implications to avoide its negative effects. (shrink)

The masked priming paradigm has been extensively used to investigate the indirect impacts of unconscious stimuli on conscious behaviors, and the congruency effect of priming on free choices has gained increasing attention. Free choices allow participants to voluntarily choose a response from multiple options during each trial. While repeated practice is known to increase priming effects in subliminal visual tasks, whether practice increases the priming effect of free choices in the masked priming paradigm is unclear. And it is also not (...) clear how the proportions of free choice and forced choice trials in one block will affect the free choice masked priming effect. The present study applied repeated practice in the masked priming paradigm and found that after training, the participants were more likely to be influenced by masked primes during free choice, but this training process did not alter the visibility of masked stimuli. In addition, this study revealed that when the proportions of free choice and forced choice trials were equal during the training stage, this enhanced effect by practice was the strongest. These results indicated that practice could enhance masked stimulus processing in free-choice, and that the learning effect may mainly be derived from the early selection and integrated processing of masked stimuli.

Assuming the existence of a measurable cardinal, we define a hierarchy of Ramsey cardinals and a hierarchy of normal filters. We study some combinatorial properties of this hierarchy. We show that this hierarchy is absolute with respect to the Dodd-Jensen core model, extending a result of Mitchell which says that being Ramsey is absolute with respect to the core model.

This is a philosophical book about the idea of human freedom in the context of Chinese philosophy on truth, the good, and beauty. The book shows that there is a coherent and sophisticated philosophical discourse on human freedom throughout the history of Chinese Philosophy in aesthetics, ethics, and epistemology. Feng Qi discusses the development of freedom in light of the Marxist theory of practice. In the history of philosophy, the relation between thought and existence, which is fundamental to philosophy, has (...) stimulated many debates. These debates, though they have assumed diverse forms in Chinese and Western philosophy, have eventually concentrated on three inquiries: the natural world (the objective material world); the human mind; and the concepts, categories, and laws that are representative forms of nature in the human mind and in knowledge. In Chinese philosophy, the three inquiries are summarized using three notions: qi (气 breath, spirit), xin (心 heart), dao (道 the Way). What relationship do the three notions have with each other? This book explores the way to human freedom through the divergent paths in Chinese philosophy. This book’s investigation of human activities brings the typical Chinese philosophical discourse from the cosmological realm into the realm of human beings as individuals. In this regard, the three inquiries can be described as being about real life, ideals, and individuals. (shrink)

As an important way for enterprises to fulfill social responsibility, corporate philanthropy has attracted much attention from the academic community. But there are still few well-targeted theoretical and empirical studies on what functions the board of directors should perform to better fulfill philanthropic responsibilities. Taking this deficiency as a breakthrough, this study focuses on Chinese state-owned and private enterprises to analyze and test the functions performed by the BOD in CP. Based on the sample of Chinese A-share listed companies from (...) 2008 to 2019, the empirical results show that the BOD of state-owned enterprises mainly performs a monitoring function in CP while that of private enterprises mainly performs a consulting function. The above findings remain valid when potential biases in the quantitative analysis are considered. Further research shows that environmental dynamism and board fault lines inhibit the performance of the above two functions. The contributions of the study include clarifying the functional characteristics of the BOD in CP and its influencing factors, revealing new theories to the formation mechanism of CP, which provide references for enterprises to optimize philanthropic decision-making. The limitation should also be emphasized that our findings are based only on Chinese contexts. (shrink)

Trust in government and social cohesion are crucial guarantees for long-term social stability. With the development of the Internet, cross-border flows of information have become increasingly easier, enabling more factors to influence people’s political perceptions and loyalty. This study explores the mechanism of governments’ impression management behaviors on trust in government and social cohesion using the questionnaire survey with college students in Shanghai as the research subjects. Impression management strategies are classified into promotive ones and protective ones herein based on (...) the social psychology theory. The results indicate that both promotive and protective impression management strategies take by governments positively affect citizens’ loyalty, and loyalty positively affects citizens’ social cohesion and the level of trust in government; moreover, the level of trust in government positively affects social cohesion. These findings provide implications for boosting the sound development of China’s political society during the transition period. (shrink)

Authoritarian leadership is of great significance to eastern countries, including China. Meanwhile, unethical employee behavior also exists in all types of social organizations. The relationship between authoritarian leadership and unethical employee behavior is worth studying. Senior leaders often do not have a direct influence on employees except for through their immediate supervisors. The leadership style of senior leaders also influences the leadership style of their subordinates. This paper studies how authoritarian manager leadership trickles down to unethical employee behavior through authoritarian (...) supervisor leadership and discusses the moderating effect of leader member exchange and an ethical climate. Through a questionnaire survey of 406 pairs of leaders, supervisors, and employees, the research results of the multilevel model show that authoritarian supervisor leadership is positively related to unethical employee behavior, authoritarian supervisor leadership mediates the relationship between authoritarian manager leadership and unethical employee behavior, LMX positively moderates the relationship between authoritarian manager leadership and authoritarian supervisor leadership and moderates the mediating effect of authoritarian supervisor leadership, and, that an ethical climate negatively moderates the relationship between authoritarian supervisor leadership and unethical employee behavior and moderates the mediating effect of authoritarian supervisor leadership.

Examining the influence of trust in fostering knowledge sharing behavior in virtual teams is of great research value in the current complex, dynamic, and competitive era of a knowledge economy. This study investigated the relationship between trust in coworkers and KSB. Based on social information processing theory and social cognitive theory, we developed a multilevel moderated mediation model where the team members’ psychological safety was considered a mediator, while team virtuality and knowledge sharing self-efficacy acted as team and individual-level moderators, (...) respectively. On surveying 282 individuals in 37 virtual teams of three Chinese internet companies, we found that TC positively affected team members’ KSB and this relationship was fully mediated by team members’ PS. Our findings also demonstrated that the effect of TC on KSB depended on the degree of TV and employees’ KSSE. Specifically, when TV and KSSE were higher, the TC–PS and PS–KSB relationship and the mediating effects of PS in the TC–PS–KSB relationship were all stronger. Our study extends the trust-KSB literature by identifying the psychological mechanism and boundary conditions in the TC-KSB relationship. Moreover, our findings also offer valuable managerial implications for virtual team managers on facilitating team members’ PS and KSB. (shrink)

A vehicle-commodity matching problem is presented for service providers to reduce the cost of the logistics system. The vehicle classification model is built as a Gaussian mixture model, and the expectation-maximization algorithm is designed to solve the parameter estimation of GMM. A nonlinear mixed-integer programming model is constructed to minimize the total cost of VCMP. The matching process between vehicle and commodity is realized by GMM-EM, as a preprocessing of the solution. The design of the vehicle-commodity matching platform for VCMP (...) is designed to reduce and eliminate the information asymmetry between supply and demand so that the order allocation can work at the right time and the right place and use the optimal solution of vehicle-commodity matching. Furthermore, the numerical experiment of an e-commerce supply chain proves that a hybrid evolutionary algorithm is superior to the traditional method, which provides a decision-making reference for e-commerce VCMP.

Purpose As an enabler of environmental sustainability, Green information technology has become an emerging topic of interest in both academic and business communities. Despite its importance, confusions exist in the content and scope of Green IT practice. The purpose of this paper is to provide an overview of the current state of Green IT practice. Design/methodology/approach First 14 widely accepted Green IT practice topics were identified from prior research and a taxonomy was developed to categorize them. Using the content analysis (...) method, these topics were examined in the sustainability reports of 30 IT companies in 2014 Fortune 500. A quantity–quality portfolio framework was developed and applied to measure and assess the Green IT practices of the selected samples. Findings Currently, the Green IT practice is still in its infancy. Both research and practice attention are now focusing on IT’s direct impacts and enabling impacts, while overlooking the systemic impacts, on natural environment. The possible reasons for the current state and the recommendations for future research and practice are provided. Originality/value Theoretically, this paper identified 14 widely accepted Green IT practice topics and developed a taxonomy for categorizing them. The taxonomy and topics provide a theoretical basis for future examination on Green IT practice-related issues. Practically, the findings of this paper provide guidelines for Green IT practice and directions for both Green IT developers and adopters in their decision-making. (shrink)

Article aims to explore Augustine's "two cities" theory. First, a brief discussion of the "City of God" writing background and the main structure; Secondly, in both religious and secular aspects of life on the analysis of the "City of God" on the "two cities" of the main points; again, three perspectives of the "two cities" theory of history and ideological background. Although the "two cities" doctrine embodies a form with two points tend to think, but both different from the ontological (...) dualism and the dualism of body and soul, but also avoids the complex social reality for too absolute two points. The focus of this study is Augustine's doctrine of the "Two Cities." The first part treats the background and the structure of the City of God. In the second and the third part, the essay examines both the religious and the temporal aspect of this doctrine. Finally, the historical and intellectual background of the doctrine is discussed. The author argues that even though the doctrine of the "Two Cities" manifests a dualistic tendency in the thought of Augustine, it can hardly be labeled as a dualism. (shrink)

Faced with increasing global environmental problems, organizational scholars and practitioners have increasingly considered how to promote employee pro-environmental behavior. This research seeks to expand our understanding of the facilitators of employee pro-environmental behavior from the perspective of leader expectations. Drawing on behavioral confirmation theory, we propose that leader pro-environmental expectations are expressed in active support for the environment, which subsequently facilitates employee pro-environmental behavior, thus rising to meet the leader's initial expectations. Furthermore, we argue that the above relationship becomes stronger (...) with the increase in employees' pro-environmental self-expectations. Based on data from 197 leader-employee dyads, the results of regression analysis showed that leader pro-environmental expectations are positively related to employee pro-environmental behavior via demonstrated leader support for the environment, and this indirect relationship is positively moderated by employee pro-environmental self-expectations. When an employee holds high pro-environmental expectations for himself or herself, a leader with high pro-environmental expectations will render support for the environment, which ultimately increases employee pro-environmental behavior. Our findings highlight the relevance of incorporating behavioral confirmation theory into the pro-environmental behavior literature and provide valuable insights for managers on how to effectively promote employee pro-environmental behavior.

We investigate the dynamics of a nonautonomous stochastic SIS epidemic model with nonlinear incidence rate and double epidemic hypothesis. By constructing suitable stochastic Lyapunov functions and using Has’minskii theory, we prove that there exists at least one nontrivial positive periodic solution of the system. Moreover, the sufficient conditions for extinction of the disease are obtained by using the theory of nonautonomous stochastic differential equations. Finally, numerical simulations are utilized to illustrate our theoretical analysis.

In this paper, we propose the model averaging estimation method for multiplicative error model and construct the corresponding weight choosing criterion based on the Kullback–Leibler divergence with a hyperparameter to avoid the problem of overfitting. The resulting model average estimator is proved to be asymptotically optimal. It is shown that the Kullback–Leibler model averaging estimator asymptotically minimizes the in-sample Kullback–Leibler divergence and improves the forecast accuracy of out-of-sample even under different loss functions. In simulations, we show that the KLMA estimator (...) compares favorably with smooth-AIC estimator, smooth-BIC estimator, and Mallows model averaging estimator, especially when some nonlinear noise is added to the data generation process. The empirical applications in the daily range of S&P500 and price duration of IBM show that the out-of-sample forecasting capacity of the KLMA estimator is better than that of other methods. (shrink)
