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)

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.

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.

Family obligation, which has an exceptionally high salience in traditional Chinese society, continues to be significant in contemporary China. In family relations in particular sentiments and practices morphologically similar to those associated with xiao remains intact in so far as an enduring set of expectations concerning age-based obligation continues to structure behavior toward others. Researchers pursuing the theme of “individualization” in Chinese society, on the other hand, argue that family obligations and filial sentiments have substantially weakened. The present paper will (...) show that under conditions of cultural and social change in China filial behavior through family obligation continues to play an important role even though the conventions associated with the relevant expectations, attitudes and emotions have undergone significant change. The paper argues that the culture-system develops not merely through an internal dynamic and that family obligation must be understood in terms of the social and material context in which it operates and the nature of the motivations and imagery of the people that practice it.

We prove that Rado's Conjecture implies that the nonstationary ideal on ω 1 is presaturated.

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.

Corruption has been a major obstacle to economic growth around the world. In this paper, we examine how firms interact with corrupt government officials either to minimize the impact of corruption on their operations or to maximize their benefit of paying a bribe. Our estimates show that firms know exactly what they need and use their limited resources to bribe only relevant government authorities. In other words, firms are rational bribers who know exactly what they need and optimize their bribes (...) to fulfill that need. This type of intentional bribery could be reduced by enhanced institutional environments and improved openness of the economy. (shrink)

Continuous environmental concerns regarding construction industry have been driving general constructors of mega infrastructure projects to incorporate green contractors. Although conventional multiple attributes decision-making methodologies have provided feasible ways to select contractor, high complexity in scenarios of megaprojects still challenges existing MADM methods in concurrently accommodating three key issues of decision hesitancy, attributes interdependency, and group attitudinal character. To elicit decision-makers’ hesitant fuzzy assessments more objectively and comprehensively, we define an expression tool called interval-valued dual hesitant fuzzy uncertain unbalanced linguistic (...) set and develop aggregation operators through its operations. To exploit attributes interdependency, we establish a synthesized attributes’ weighting model to fuse an attributes interdependency-based weighting vector and an argument-dependent weighting vector, which are, respectively, derived through Decision-Making and Trial Evaluation Laboratory technique and maximizing deviation method. To effectively utilize decision-makers’ group attitudinal characters, we also develop a TOPSIS-based method to rationally transform group ideal attitudes into order-inducing vectors. On the strength of the above methods, an integrated MADM approach is then constructed. Finally, illustrative case study and experiments are conducted to validate our approach. (shrink)

School moral education in any country is carried out in a particular social and cultural context. The renewal of policy and practice in moral education in China has come about because of a rapidly changing Chinese society, as a result of the government's ‘reform and opening up’ policy since the end of the 1970s. The consequent changes in the Chinese economy, politics and culture are innovatory and challenging. It is these changes that have brought about, and will continue to bring (...) about, new ideas and practices in moral education. This paper describes how Chinese moral education has been influenced according to recent social changes and modernization in China, including the formation of the market economy, the impact of globalization, mass media and the Internet, cultural diversity and value pluralism, trends to democratization in politics, and structural changes in the family. It also considers the kind of social issues and challenges which are being dealt with and anticipated in policy, theory and practice in contemporary Chinese moral education. (shrink)

The Biliu River is the largest river in Dalian. The occurrence of floods and droughts in this basin has extremely important impacts on local industry, agriculture, and urban development. For a long time, the annual distribution of precipitation in the Biliu River Basin is extremely uneven, the river runoff varies greatly from year to year and season to year, floods and droughts occur frequently, and serious soil erosion results in fragile ecological environment and severe shortage of water resources. In this (...) paper, the spatial and temporal changes of rainfall and runoff in the Biliu River Basin are studied through the coupling of the MIKE 11 model and the MIKE SHE model. The hydrological changes in the Biliu River Basin are simulated. The coupled model is verified by monthly runoff data from 1996 to 2015, and the simulation values are found to be true. The values match well. Based on the cyclical pattern of precipitation and runoff in the Biliu River Basin, the rainfall and runoff data in the Biliu River Basin from 2016 to 2030 are derived. The MIKE SHE/MIKE 11 coupling model is used to predict the Biliu River from 2016 to 2030. The results show that flood disasters are expected to occur in August 2020, July 2025, and July 2030, which can provide a basis for hydrological management in the Biliu River Basin. (shrink)

Computational modeling and eye-tracking were used to investigate how phonological and semantic information interact to influence the time course of spoken word recognition. We extended our recent models to account for new evidence that competition among phonological neighbors influences activation of semantically related concepts during spoken word recognition . The model made a novel prediction: Semantic input modulates the effect of phonological neighbors on target word processing, producing an approximately inverted-U-shaped pattern with a high phonological density advantage at an intermediate (...) level of semantic input—in contrast to the typical disadvantage for high phonological density words in spoken word recognition. This prediction was confirmed with a new analysis of the Apfelbaum et al. data and in a visual world paradigm experiment with preview duration serving as a manipulation of strength of semantic input. These results are consistent with our previous claim that strongly active neighbors produce net inhibitory effects and weakly active neighbors produce net facilitative effects. (shrink)

The ancient aesthetics of yijing has played a crucial role in traditional Chinese philosophy, literature and art since the eighth century CE. Defined variously by early and contemporary writers, yijing links an artist's emotional domain to objects in the world. This article conceptualises yijing as an ecological aesthetics and distinguishes it from an environmental aesthetics. In particular, two aspects of yijing render it an eco-aesthetics: subject–object correspondence (or ‘engagement'); and empathic identification with the environment (or ‘bio-empathy'). Three brief case studies (...) from urban planning, environmental conservation and the creative arts demonstrate the contemporary importance of yijing to ecological issues. (shrink)

With the advancement of China’s economic transformation, the impact of economic policy uncertainty on family firms has become increasingly significant. The “familism” of family firms makes them more motivated to maintain family harmony, pursue innovative activities, and the long-term development of enterprises when faced with economic policy uncertainty. In this paper, we employed the data of listed Chinese family firms from 2010 to 2018 to analyze the impact of economic policy uncertainty on family business innovation activities, analyze the inherent characteristics (...) of family firm innovation, and find the path that enables the innovative activities of family firms and provides a valuable experience for the innovation of private enterprises in economic policy uncertainty. We provide evidence that economic policy uncertainty positively relates to family firm innovation. Moreover, the relationship is affected by factors such as directors’ executive background and access to state-owned equity. Further analysis indicates that economic policy uncertainty can promote family firms’ innovation activities by improving their risk-taking, internal capital market circulation, and reducing political connections.

This article uses the “Green Credit Guidelines” issued in 2012 as a quasi-natural experiment, using the statistics of A-share listed companies from 2008 to 2017, using the PSM-DID model to examine the effect and mechanism of green credit policies on the investment efficiency of heavily polluting companies, and taking into consideration the heterogeneous influence of the financial ecological environment on the relationship between the two. The research indicates that, after the Green Credit Guidelines were promulgated, the investment efficiency of heavy-polluting (...) companies has been slightly improved compared with non-heavy-polluting companies and that the impact is more obvious in regions with better financial ecological environment. The research conclusions confirm the beneficial effects of the Green Credit Guidelines policy on the prudent investment of companies that cause serious pollution to the environment and improve investment efficiency, a provision of empirical evidence for financial leverage to drive the green economy transformation.
