This paper uses the 5-five-minute high-frequency data of energy-listed companies in China's A-share market to extract the jump of energy stock prices and build a dynamic stock price jump complex network. Then, we analyze the clustering effect of the complex network. The research shows that the energy stock price jump is an important part of stock price volatility, and the complex network of energy stock jump risk has obvious time-varying characteristics. However, the infection problem of stock price jump risks needs (...) specific analysis. China's coal industry has an important influence on the development of China's energy industry. According to the clustering analysis results of the network community, the clustering effect of the network community has time-varying characteristics. After October 2017, the clustering effect of the jumping risk of the coal industry and the new energy industry is obvious. The risk contagion within the new energy industry community is a key point for the development of the new energy industry. (shrink)

Given a target area and a location-aware social network, the location-aware influence maximization problem aims to find a set of seed users such that the information spread from these users will reach the most users within the target area. We show that the problem is NP-hard and present an approximate algorithm framework, namely, TarIM-SF, which leverages on a popular sampling method as well as spatial filtering model working on arbitrary polygons. Besides, for the large-scale network we also present a coarsening (...) strategy to further improve the efficiency. We theoretically show that our approximate algorithm can provide a guarantee on the seed quality. Experimental study over three real-world social networks verified the seed quality of our framework, and the coarsening-based algorithm can provide superior efficiency. (shrink)

Background:There is controversy concerning the use of physical restraint. Despite this controversy, some nurses still consider the application of physical restraint unavoidable for some of their clients.Aim:Identify the perceptions and practice of physical restraint in China.Research design:This was a descriptive study that combined qualitative interviews with a quantitative cross-sectional survey.Participants:A total of 18 nurses were interviewed and 330 nurses were surveyed.Ethical considerations:Approval of the study was obtained from the hospital ethics committee. Permission to conduct the study was obtained from the (...) director of nursing. Participants were assured that their participation is voluntary.Results:Physical restraint was commonly used to protect patients’ safety. Naturally, intensive care unit nurses used physical restraint much more frequently than general medical/surgical ward nurses ( p < 0.01). In addition, night shift nurses tended to use physical restraint more frequently.Conclusion:Nursing managers should be aware of the role nurses play in the use of physical restraint. In-service training regarding the proper use of physical restraint should be strengthened and nurse staffing levels should be improved in order to minimize the use of physical restraint in China.

This study aims to explore effective ways to improve college students’ entrepreneurial self-efficacy and intentions through entrepreneurship education. The survey used a random sample of 804 college students in Zhejiang Province, China. The results show that: In terms of the characteristics of entrepreneurial intention, there are significant differences in gender, entrepreneurial experience, entrepreneurial competition experience, and family background of self-employment. There are significant differences in the characteristics of entrepreneurship education in gender, entrepreneurial competition experience, and the family background of self-employment. (...) In the relationship among entrepreneurship education, entrepreneurial self-efficacy, and entrepreneurial intention, entrepreneurship education is significantly and positively related to entrepreneurial self-efficacy and entrepreneurial intention. Entrepreneurial self-efficacy is significantly and positively associated with entrepreneurial intention. Entrepreneurial self-efficacy plays a complete mediating role between entrepreneurship education and entrepreneurial intention. Entrepreneurial self-efficacy also has a suppressing effect on the relationship between the two. Entrepreneurial competition experience moderates the second half of the mediating effect of entrepreneurial self-efficacy. Finally, the study offers several proposals for the teaching practice of entrepreneurship education. (shrink)

The field service scheduling problem is the key problem in field services. Field service pays particular attention to customer experience, that is, customer satisfaction. Customer satisfaction described by customer behavior characteristics based on the prospect theory is considered as the primary optimization goal in this paper. The knowledge of the insertion feasibility on the solution is analysed based on the skill constraint and time window. According to the knowledge, an initialization method based on the nearest heuristic algorithm is constructed. Based (...) on the prior knowledge of the FSSP and the endowment of the Fruit Fly Optimization Algorithm, two operators are defined according to the matrix encoding method. Based on these two operators, three search strategies are then proposed, and the smell-based search strategy and vision-based search strategy for the FOA are redesigned. To verify the performance of the algorithms, the proposed operators and strategies are tested and analysed in the well-known benchmark. Through comparison with the state-of-the-art algorithms, the results show that the proposed HFOA is an effective and efficient method to solve the FSSP with customer satisfaction. (shrink)

Interactions with teachers and peers are critical for children’s social, behavioral, and academic development in the classroom context. However, these two types of interpersonal interactions in the classroom are usually pursued via separate lines of inquiries. The current study bridges these two areas of research to examine the way in which teachers influence child-perceived peer social support and peer victimization for 2,678 children within 183 classrooms in preschool through grade three. Two levels of teacher influence are considered, namely teacher-child closeness (...) and conflict relationships at the child-level, and teacher management of interpersonal interactions at the classroom-level. Results of multilevel regression models showed that teacher-child closeness was associated with the growth of child-perceived peer social support from fall to spring, whereas teacher-child conflict and teachers’ behavior management practices were associated with the change in child-perceived peer victimization across the academic year. These associations were unique and above and beyond the influence of children’s actual peer social interactions, including reciprocal friendships and the collective classroom reputation of peer victimization. Collectively, findings highlight the multi-faceted teacher roles in shaping children’s perceptions of their peer social experiences during the earliest years of schooling. (shrink)

Along with the rapid application of new information technologies, the data-driven era is coming, and online consumption platforms are booming. However, massive user data have not been fully developed for design value, and the application of data-driven methods of requirement engineering needs to be further expanded. This study proposes a data-driven expectation prediction framework based on social exchange theory, which analyzes user expectations in the consumption process, and predicts improvement plans to assist designers make better design improvement. According to the (...) classification and concept definition of social exchange resources, consumption exchange elements were divided into seven categories: money, commodity, services, information, value, emotion, and status, and based on these categories, two data-driven methods, namely, word frequency statistics and scale surveys, were combined to analyze user-generated data. Then, a mathematical expectation formula was used to expand user expectation prediction. Moreover, by calculating mathematical expectation, explicit and implicit expectations are distinguished to derive a reliable design improvement plan. To validate its feasibility and advantages, an illustrative example of CoCo Fresh Tea & Juice service system improvement design is further adopted. As an exploratory study, it is hoped that this study provides useful insights into the data mining process of consumption comment. (shrink)

Creativity has become prevalent in the routine work of knowledge employees in contemporary enterprises. From the perspective of ambidexterity, drawing upon expectancy theory and self-determination theory, the present study highlights the driver behind proactive and responsive creativity. Using two-stage longitudinal data collected from 373 knowledge employee-supervisor dyads in information and manufacturing companies in China, the results show that: performance-contingent rewards have an inverted U-shaped influence on proactive creativity and a U-shaped influence on responsive creativity; performance-contingent rewards have an inverted U-shaped (...) influence on autonomous and controlled motivation; autonomous motivation has a positive influence on proactive creativity, but controlled motivation has a negative influence on responsive creativity; autonomous and controlled motivation play a partly mediating mechanism in the non-linear effects of performance-contingent rewards on proactive and responsive creativity, respectively. Managers should enhance the ambidextrous ability to deal with proactive and responsive creativity and establish an applied and dynamic policy of performance-contingent rewards intensity to drive ambidextrous creativity.

As an important corporate governance mechanism, directors’ and officers’ liability insurance is theoretically associated with corporate financialization because it directly affects incentive constraints and risk preference of enterprise managers. However, whether there is a causal relationship in fact has not been sufficiently empirically investigated. Using a sample of Chinese non-financial listed companies in Shanghai and Shenzhen A-shares from 2008 to 2020, this paper empirically analyzes how corporate subscription to directors’ and officers’ liability insurance affects corporate financialization and examines the mediating (...) role played by risk-taking, financing constraints, and audit quality. The study finds that corporate subscription to D&O insurance increases corporate financialization. In terms of the influential mechanism, subscription to D&O insurance promotes financialization by increasing risk-taking, alleviating financing constraints, and improving audit quality. In addition, the results in the heterogeneity analysis suggest that the promotion of financialization by subscribing to D&O insurance is more significant in state-owned enterprises, growth and decline stage enterprises, and non-dual-employment enterprises.

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)

As the aging population, including frail older people, continues to grow in Mainland China, quality of life and end-of-life care for frail older people has attracted much attention. Advance care planning is an effective way to improve end-of-life care for people with advanced diseases, and it is widely used in developed countries; however, it is a new concept in Mainland China. The effects of advance care planning and its acceptability in Mainland China are uncertain because of its culture-sensitive characteristics. The (...) objective of this article is to discuss the serious social issue of caring for frail older people and illustrate the possibility of implementing advance care planning in nursing homes in Mainland China through a review of relevant literature, which will focus on legislation, healthcare system engagement, public engagement, and cultural issues. Recommendations to promote and implement advance care planning include choosing nursing homes as a proper setting, establishing an ethical climate, and enhancing public awareness. (shrink)

Integrating norms of reciprocity, affect theory of social exchange, and ambivalence literature, we investigated how leader-member exchange (LMX) ambivalence influences employees’ interpersonal behaviors toward supervisors. Study 1, with a time-lagged field method, revealed that LMX ambivalence was positively related to _both_ employee-rated supervisor-directed helping and deviant behaviors and that such relationships were mediated by emotional ambivalence toward supervisors. We also confirmed the amplification effects of workplace gossip about supervisors (WGS). Specifically, while receiving more positive WGS (PWGS) or less negative WGS (...) (NWGS) could strengthen the positive relationship between emotional ambivalence and supervisor-directed helping behaviors, receiving less PWGS or more NWGS would accentuate the positive effect of emotional ambivalence on supervisor-directed deviant behaviors. Study 2 replicated our results with a scenario-based method and offered evidence for the mediating effect of emotional ambivalence toward supervisors. Study 3 included supervisor-rated helping and deviant behavior and a subjective measure of emotional ambivalence and again confirmed the mediating role of emotional ambivalence. Our findings extend knowledge of the interpersonal consequences of LMX ambivalence. (shrink)

Schizophrenia is considered as a self-disorder with disordered local synchronous activation. Previous studies have reported widespread dyssynchrony of local activation in patients with SZ, which may be one of the crucial physiological mechanisms of SZ. To further verify this assumption, this work used a surface-based two-dimensional regional homogeneity approach to compare the local neural synchronous spontaneous oscillation between patients with SZ and healthy controls, instead of the volume-based regional homogeneity approach described in previous study. Ninety-seven SZ patients and 126 HC (...) were recruited to this study, and we found the SZ showed abnormal 2dReHo across the cortical surface. Specifically, at the global level, the SZ patients showed significantly reduced global 2dReHo; at the vertex level, the foci with increased 2dReHo in SZ were located in the default mode network, frontoparietal network, and limbic network ; however, foci with decreased 2dReHo were located in the somatomotor network, auditory network, and visual network. Additionally, this work found positive correlations between the 2dReHo of bilateral rectus and illness duration, as well as a significant positive correlation between the 2dReHo of right orbital inferior frontal gyrus with the negative scores of the positive and negative syndrome scale in the SZ patients. Therefore, the 2dReHo could provide some effective features contributed to explore the pathophysiology mechanism of SZ. (shrink)

Schizophrenia is a serious mental illness characterized by a disconnection between brain regions. Transcranial magnetic stimulation is a non-invasive brain intervention technique that can be used as a new and safe treatment option for patients with schizophrenia with drug-refractory symptoms, such as negative symptoms and cognitive impairment. However, the therapeutic effects of transcranial magnetic stimulation remain unclear and would be investigated using non-invasive tools, such as functional connectivity. A longitudinal design was adopted to investigate the alteration in FC dynamics using (...) a dynamic functional connectivity approach in patients with schizophrenia following high-frequency repeated transcranial magnetic stimulation with the target at the left dorsolateral prefrontal cortex. Two groups of schizophrenia inpatients were recruited. One group received a 4-week high-frequency rTMS together with antipsychotic drugs, while the other group only received antipsychotic drugs. Resting-state functional magnetic resonance imaging and psychiatric symptoms were obtained from the patients with schizophrenia twice at baseline and after 4-week treatment. The dynamics was evaluated using voxel- and region-wise FC temporal variability resulting from fMRI data. The pattern classification technique was used to verify the clinical application value of FC temporal variability. For the voxel-wise FC temporary variability, the repeated measures ANCOVA analysis showed significant treatment × time interaction effects on the FC temporary variability between the left DLPFC and several regions, including the thalamus, cerebellum, precuneus, and precentral gyrus, which are mainly located within the cortico-thalamo-cerebellar circuit. For the ROI-wise FC temporary variability, our results found a significant interaction effect on the FC among CTCC. rTMS intervention led to a reduced FC temporary variability. In addition, higher alteration in FC temporal variability between left DLPFC and right posterior parietal thalamus predicted a higher remission ratio of negative symptom scores, indicating that the decrease of FC temporal variability between the brain regions was associated with the remission of schizophrenia severity. The support vector regression results suggested that the baseline pattern of FC temporary variability between the regions in CTCC could predict the efficacy of high-frequency rTMS intervention on negative symptoms in schizophrenia. These findings confirm the potential relationship between the reduction in whole-brain functional dynamics induced by high-frequency rTMS and the improvement in psychiatric scores, suggesting that high-frequency rTMS affects psychiatric symptoms by coordinating the heterogeneity of activity between the brain regions. Future studies would examine the clinical utility of using functional dynamics patterns between specific brain regions as a biomarker to predict the treatment response of high-frequency rTMS.

Shape memory alloy- based actuators are widely applied in the compliant actuating systems. However, the measured data of the SMA-based compliant actuating system reveal the input-output hysteresis behavior, and the actuating precision of the compliant actuating system could be degraded by such hysteresis nonlinearities. To characterize such nonlinearities in the SMA-based compliant actuator precisely, a Jiles-Atherton model is adopted in this paper, and a modified particle swarm optimization algorithm is proposed to identify the parameters in the Jiles-Atherton model, which is (...) a combination of several differential nonlinear equations. Compared with the basic PSO identification algorithm, the designed MPSO algorithm can reduce the local optimum problem so that the Jiles-Atherton model with the identified parameters can show good agreements with the measured experimental data. The good capture ability of the proposed identification algorithm is also examined through the comparisons with Jiles-Atherton model using the basic PSO identification algorithm. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Reply to Discussion of Origins of Moral-Political Philosophy in Early China:Contestation of Humaneness, Justice, and Personal FreedomTao Jiang (bio)I am grateful to all six commentators for their careful reading of and thoughtful engagements with my book, especially to Sungmoon Kim for spearheading this group effort. In the book, Origins of Moral-Political Philosophy in Early China: Contestation of Humaneness, Justice, and Personal Freedom, I try to tell a new (...) story about the foundational period of Chinese philosophy, with a focus on the deliberations of normative values in the respective texts. I make three key points. First, the central intellectual challenge during the Chinese classical period was how to negotiate the relationships between the personal, the familial, and the political domains (sometimes also characterized as the relationship between the private and the public) when philosophers were re-imagining and re-conceptualizing a new moral-political order. Philosophers offered a dazzling array of competing visions for that newly imagined order. Second, the competing visions can be characterized as a contestation between partialist humaneness and impartialist justice as the guiding norms of the newly imagined order, with the Confucians, the Mohists, the Laoists, and the so-called fajia thinkers being the major participants. This was the mainstream intellectual project that dominated the classical debate and set the terms and the parameters of that debate. Third, Zhuangzi and the Zhuangists were the outliers of the mainstream moral-political discourse during this period. They rejected the very parameters of humaneness versus justice in the mainstream debate and instead represented a lone voice advocating personal freedom. For the Zhuangists, the mainstream debate was intellectually banal, morally misguided, and politically dangerous. One critical overall context for these [End Page 475] philosophical endeavors is that they took place within an evolving understanding of Heaven and its relationship with humans.Loy Hui-chiehLet me begin with Loy Hui-chieh's comment on the book's methodology, laid out in the Introduction to my book, as it pertains to the broader norms of practices in contemporary analytic philosophy and Chinese philosophy. The purpose of the methodological reflection in the Introduction is to provide some tools in dealing with the challenges to Chinese philosophy from Sinology (historical and philological approaches to classical Chinese texts) and Western philosophy within Western academia. I argue that scholars of Chinese philosophy, situated between Sinology and Western philosophy in the West, need to be mindful of the constructed nature of the scholarly objects shaped by disciplinary norms and practices. Specifically, scholars of Chinese philosophy, in their philosophical endeavors, construct their scholarly objects based on the operative but often implicit ideas of inherited text, textual author, and textual intent, as opposed to Sinologists who are more motivated by their scholarly objects of original text, historical author, and authorial intent.Loy's comment frames my methodological reflections primarily through the lens of history of philosophy. There is another critical element in this endeavor, namely the philosophical lineage upon which the study of philosophy in the West has been built, conceptually and institutionally. With respect to history of philosophy, Loy's questions concern the presentist orientation in analytic philosophy and its relationship with history of philosophy. As he aptly points out, analytic philosophers are ultimately uninterested in the correct interpretation of who said what in the history of philosophy. Rather their interest lies in philosophical issues and problems themselves, irrespective of how/when/by whom those issues are formulated. Scholars in history of philosophy seek to convince analytic philosophers that the texts and the ideas they study should be recognized as good philosophy by contemporary standards, not just their historical values. The presentist bias is clear. Of course, we do not have to subscribe to such a norm since the present is not necessarily the be-all and end-all of everything philosophers are concerned with, or at least it should not be. Otherwise, our philosophical reflections, even those with the presentist concerns, would be significantly impoverished. As a profession, contemporary philosophers regularly draw upon history of ideas, especially from the Hellenistic and early modern European traditions, to frame their arguments and to seek new inspirations. Such a practice is heavily dependent on the... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and History, Customs and EthicsHui-Chieh Loy (bio)Origins of Moral-Political Philosophy in Early China: Contestation of Humaneness, Justice, and Personal Freedom. By Tao Jiang. New York: Oxford University Press, 2021.Tao Jiang's Origins of Moral-Political Philosophy in Early China is a serious tour de force of a study. In many ways, I am reminded of Angus Graham's Disputers of the Tao and Benjamin Schwartz' The World of Thought (...) in Ancient China—but updated. A signal difference is that it is more constrained in its coverage of figures, texts, and especially in having the topical focus upon moral-political philosophy. At the same time and within the chosen (narrower) confines, it often examines its subject in greater detail and draws on more recent discussions.One neat thing that Jiang does is to deliberately weave in explicit discussions of how each subsequent thinker or text incorporated or criticized ideas associated with earlier thinkers. (I formulated it this way since there isn't enough historical evidence about who-actually-read-what in the ancient world, citation practices being what they were.) In this regard, I am especially heartened to read, for example, the sections on "Traces of Mohist Elements in the Laozi" (3.3.2), and "Mohist Elements in Han Feizi's Thought" (7.3.3).By no means should the desultory remarks below be counted as a full review or assessment (impressionistically, this is the sort of book I will recommend that my grad students read—there, I've said it). Think of them as humble shards of pottery thrown in the hope for some jade in response. To make my task more focused, I will comment on the Sinology versus Philosophy distinction, and Jiang's treatment of the Mohists.I. Philosophy and History of PhilosophyAn important part of Jiang's Introduction is devoted to discussing the situation of Chinese Philosophy as a field in the Western Academy, caught between Sinology on the one hand and academic Philosophy on the other. Due to the different scholarly objectives and norms in the two disciplines, scholars working on Chinese Philosophy often find themselves caught [End Page 420] between two distinct audiences who demand different things. Jiang's aim is to propose an "interpretive model to distinguish two sets of scholarly objects operative in Sinology and philosophy. These objects are related and at times overlap, but they are also often irreducibly distinct, i.e., original text versus inherited text, historical author versus textual author, and authorial intent versus textual intent, with the former in the pairs belonging to Sinologists and the latter to philosophers" (p. 7). In general, I am highly sympathetic to the distinctions Jiang draws. But I do wonder if we need to step back and start from a wider context involving what is potentially a deeper divide.Now, it is entirely a caricature but the joke around the water cooler is that philosophers—especially those of a more "analytic" bent—often exude the attitude that they are not in the business of reading old books. Their project is one focused on issues and problems and puzzles that are ultimately about the natural and human world, rather than about texts and their interpretation, or even the historical thinkers themselves. To give some obvious examples, the intellectual questions they see themselves as answering are the likes of:• Can we know that God exists, if God exists at all?• What is the nature of moral claims? Do they admit of truth and falsity?• How is causation related to possibility?• Is a logic that dispenses with the law of non-contradiction viable?• What are the necessary and sufficient conditions of knowledge?• Is abortion morally justifiable?Sometimes the questions they ask even infringe on the results and insights from nearby fields, for instance linguistics and the natural and empirical sciences:• What is time?• Can a presentist conception of time be made consistent with contemporary physics?• What is the nature of consciousness? How is it related to physical neural states or informational computational processes?• Can computers be sentient?• How is morality related to the passions?• In what sense is a political order that does justice to diversity of moral beliefs...
