Against the scourge of the COVID-19 pandemic, college students’ learning engagement has become a key issue in universities and society. Guided by the theories of existential positive psychology and social perception, we explored the positive effect of a growth mindset on learning engagement during the COVID-19 pandemic. A total of 1,040 college students from universities in Henan Province of China effectively completed online questionnaires. The results showed that growth mindset was positively related to learning engagement and negatively associated with perceived (...) COVID-19 event strength and perceived stress; perceived COVID-19 event strength was positively related to perceived stress, while perceived COVID-19 event strength and perceived stress were negatively associated with learning engagement. Growth mindset affected learning engagement through three indirect paths: the mediating role of perceived COVID-19 event strength, the mediating role of perceived stress, and the serial mediating role of both perceived COVID-19 event strength and perceived stress. The results indicated that the growth mindset could contribute to college students’ learning engagement through the roles of perceived COVID-19 event strength and perceived stress during the COVID-19 pandemic. This study advances the understanding of the mechanism underlying the relationship between growth mindset and college students’ learning engagement during the COVID-19 pandemic. Furthermore, the findings of the study have important implications for promoting college students’ learning engagement during the pandemic. (shrink)

Aiming at the oscillation suppression of spacecraft with large flexible appendages, we propose a control strategy using H∞ control. The weighting functions are designed for the specific flexible modes of the spacecraft and the frequency of harmonic interference in its operating environment. Taking into account the structural uncertainty of systematic modeling and the comprehensive performance requirements of system bandwidth constraint and attitude stability, the H∞ comprehensive performance matrix is constructed. A space telescope with a large flexible solar array is presented (...) as an illustrative example, and a control design that meets the requirement for pointing accuracy is proposed. The simulation results show that the designed controller satisfies the requirements of attitude stability and high pointing accuracy and has effectively suppressed the disturbance of endemic frequency. The design scheme and selection method of the weight function shown in this paper can be a reference for the controller design for oscillation suppression of this type of spacecraft with flexible structures.

To solve the problem of user privacy disclosure caused by attacks on anonymous areas in spatial generalization privacy protection methods, a K and P Dirichlet Retrieval method based on k-anonymity mechanism is proposed. First, the Dirichlet graph model is introduced, the same kind of information points is analyzed by using the characteristics of Dirichlet graph, and the anonymous set of users is generated and sent to LBS server. Second, the relationship matrix is generated, and the proximity relationship between the user (...) position and the target information point is obtained by calculation. Then, the private information retrieval model is applied to ensure the privacy of users’ target information points. Finally, the experimental results show that the KPDR method not only satisfies the diversity of l 3 / 4, but also increases the anonymous space, reduces the communication overhead, ensures the anonymous success rate of users, and effectively prevents the disclosure of user privacy.

Sleep quality, personality, and cognitive load potentially increase second language writing anxiety and subsequently affect SLW achievement. This study investigates the predictions of sleep quality, personality, and cognitive load toward SLW anxiety and achievement in a computer-based test. Participants included 172 voluntary undergraduates majoring in English as foreign language. SLW anxiety in a computer-based test, sleep disturbance, personality and cognitive load was assessed with the SLW Anxiety Inventory, Pittsburg Sleep Quality Index, Type-D Personality, and cognitive load questionnaires. A structural equation (...) modeling approach was applied to examine the interdependence among the observed variables. An adequate-fit SLW anxiety model was built. The structural model showed that sleep disturbance, social inhibition personality, and computer-induced cognitive load were significant predictors of SLW anxiety in a computer-based test. Subsequently, SLW anxiety in a computer-based test and computer-induced cognitive load were significant negative predictors of computer-based SLW achievement. (shrink)

Objective: This study aimed to contribute to understanding the mechanisms underlying the association between empowering motivational climate in physical education and social responsibility among high school students, and have important implications for interventions aimed at improving social responsibility among high school students.Methods: Through the quota sampling, 802 students that complied with the requirements were surveyed from Anhui Province in China. Empowering motivational climate in physical education, social responsibility, interpersonal disturbance, and general self-efficacy were assessed using standard scales. For data analysis, (...) Pearson’s correlation analysis, structural equation model test, and bias-corrected percentile Bootstrap method were carried out in turn.Results: Common method biases can be accepted in this study, and the correlation among empowering motivational climate in physical education, social responsibility, interpersonal disturbance, and general self-efficacy are all significant; Empowering motivational climate in physical education, interpersonal disturbance and general self-efficacy can all predict social responsibility significantly; Structural equation modeling indicates good fit: χ2/df = 2.86, RMESA = 0.068, CFI = 0.92, NNFI = 0.91, NFI = 0.90, GFI = 0.93. It indicates that interpersonal disturbance and general self-efficacy can play mediating roles between empowering motivational climate in physical education and social responsibility, respectively. After that, interpersonal disturbance as well as general self-efficacy in turn plays the chain mediating effect in the relationship between empowering motivational climate in physical education and social responsibility. The effect size of the mediating effect of interpersonal disturbance and general self-efficacy in the relationship between empowering motivational climate in physical education and social responsibility is 0.048 and 0.148, respectively, and the effect size of the chain mediating effect is 0.031.Conclusion: Empowering motivational climate in physical education not only has a direct effect on social responsibility among high school students, but also influences social responsibility by the chain mediating effect of interpersonal disturbance and general self-efficacy.

This study aims to explore the relationship between physical exercise, self-control, physical exercise atmosphere, and mobile phone addiction tendency among Chinese university students. Through the quota sampling, 1,433 students complied with the requirements were surveyed from 10 universities in China. PE, SC, PEA, and MPAT were assessed using standard scales. For data analysis, common method deviation test, mean number, standard deviation, correlation analysis and structural equation model analysis were carried out in turn. The results showed PE and MPAT were negatively (...) related. The interaction item PEA and SC could significantly positively predict the tendency of MPAT. In the high PEA group, SC had a significant negative predictive effect on the tendency of MPAT ; However, in the low PEA group, the negative predictive effect was stronger. The present study shows that PE significantly negatively predicted the tendency of MPAT, and SC played a complete mediating role in the relationship between PE and MPAT; The second half of the indirect effect of PE and MPAT was regulated by the PEA. The PEA will enhance the influence of SC on MPAT, but the high PEA will increase the level of MPAT of individuals at a very high level of SC. (shrink)

Zhu Xi’s 朱熹 interpretations systematized the Five Classics; moreover, he elevated the “Four Books” to such a supra-canonical status that these texts along with his commentaries became the core curriculum for civil service examinations from the early 13th century to the 20th century. Inquiring into what was the essential and unique Song 宋 character of Classical scholarship, we will highlight the canonical Ritual Classics because these texts were crucial for centuries, especially during the Han 漢 through Tang 唐 dynasties. We (...) show how Zhu updated ritual practices by focusing on the Yili 儀禮 as the crucial Classic for guidelines on etiquette, and also rebalanced the relation between rituals and moral “principles.” We will explore how Zhu’s systematization of moral principles and ritual did not fully resolve tensions from his major 11th-century philosophical predecessors regarding principles and ritual, as well as the Four Books and the Five Classics. Even if Dai Zhen’s 戴震 criticism of Zhu was somewhat misplaced or overstated, tensions within Zhu’s views provide us a basis for understanding Dai’s attacks and ambivalence among Qing 清 and 20th-century scholars toward Zhu Xi’s philosophy.

The scholar Jin Tian-zhu (1690 ~ 1765) was a Muslim of the Hui 回 ethnic group in the Qing dynasty who adhered to Islamic traditions handed down from generation to generation. In Qing Zhen Shi Yi, Jin Tian-zhu attempts to combine Confucianism and Islam through a simple comparison of their rituals. Jin Tian-zhu expresses his respect for Allah by attesting Allah’s existence and insisting that humans should obey Allah. He admits that in reality, besides Allah, the ruler is also (...) clearly an object of loyalty. In addition, he asserts that it is basic propriety for Muslims to be filial to their parents and that the scope of practice of filial piety must also apply to their ancestors beyond their parents. Jin Tian-zhu further expands his view of zhongxiao 忠孝 by asserting that the ultimate Muslim interest is in renlun 人倫, which he believes must be rectified. (shrink)

Despite urgent calls for more research on the integration of business ethics and the meaning of work, to date, there have been few corresponding efforts, and we know surprisingly little about this relationship. In this study, we address this issue by examining when and for whom ethical leadership is more effective in promoting a sense of work meaningfulness among employees, and their subsequent work attitudes. Drawing on the contingency theories of leadership and work meaningfulness literature, we speculate that both employees’ (...) core self-evaluation and perceived organizational support moderate the relationship, but in different ways, and these associations carry over to employees’ subsequent work attitudes in terms of job satisfaction, organizational commitment and turnover intention. We test our hypotheses with two-wave survey data collected from 377 employees. Results indicate that ethical leadership is effective in eliciting work meaningfulness and attitudes for employees higher in CSE or when POS is lower, and ineffective for those lower in CSE or when POS is higher. A supplementary analysis reveals a three-way interaction between ethical leadership, CSE and POS in predicting a sense of work meaningfulness and subsequent work attitudes. Our research cautions that ethical leadership is not a universally positive practice; it can be ineffective or even have a negative impact under some circumstances. (shrink)

As studies continue to accumulate on leader humility, it has become clear that humility in a leader is largely beneficial to his or her followers. While the majority of the empirical research on this topic has demonstrated the positive effects of leader humility, this study challenges that consensus by arguing that a leader’s humble behavior can have contradictory outcomes in followers’ voice behavior. Drawing on attachment theory, we develop a model which takes into account the ways in which leader humility (...) influences the seemingly contradictory voice behavior of followers, i.e., inducing challenging voice, and defensive voice depending on the followers’ sense of security as reflected by feeling trusted and self-efficacy for voice. The results of this empirical study confirm that leader humility influences followers’ voice in a contradictory way through their sense of security. (shrink)

Recent literature suggests that ethical leadership helps to inhibit followers’ unethical behavior, largely built on the premise that followers view ethical leaders as ethical role models and socially learn from them, thereby engaging in more ethical conduct. This premise, however, has not been adequately tested, leaving insufficient understanding concerning the conditions under which this social learning process occurs. In this study, we revisit this premise, theorizing that not all followers will equally regard the same ethical leader as being a personal (...) ethical role model, thereby bounding the leader’s effects in reducing followers’ unethical behavior. We integrate the role of follower self-concepts into social learning theory, hypothesizing that the extent followers emulate their ethical leaders is contingent on how they identify with ethics as well as the particular leader. We test our hypotheses with three-wave survey data collected from 214 employees, finding that ethical leaders are viewed as being role models only amongst followers higher in moral identity and leader identification, and that followers’ perceptions that the leader is an ethical role model mediated the effect of ethical leadership on followers’ unethical behavior. Interestingly, results for the full-model tests show that ethical leadership evokes unethical behavior amongst followers lower in both moral identity and leader identification. These results suggest that ethical leadership is not a universally useful practice to decrease unethical behavior and that a more nuanced understanding of its contingent effects needs to be better understood.
