Despite the pivotal function of knowledge sharing for enterprises in today’s highly competitive and ever-changing economic environment, the mechanism about how ethical leadership impacts employees’ knowledge sharing remains a largely unexplored domain in the literature. Drawing on the social exchange theory and social learning theory, this study examines how ethical leadership helps to encourage followers’ knowledge sharing behavior considering the dual-mediating effects of positive reciprocity and moral efficacy. A questionnaire-based survey is used to collect data in China. And structural equation modeling techniques are used to analyze the collected data in order to test the proposed hypothesis. Results show that ethical leadership has positive impact on followers’ knowledge sharing. It is also found that both positive reciprocity and moral efficacy play significant mediating effects, and they are equally important in accounting for the impact of ethical leadership on followers’ knowledge sharing. Based on the analysis results, this paper further discusses theoretical and practical implications.

Kinesins comprise a superfamily of microtubule-based motor proteins involved in essential processes in plant development, but few kinesins have been functionally identified during seed development. Especially, few kinesins that regulate cell division during embryogenesis have been identified. Here we report the functional characterization of NtKRP, a motor protein of the kinesin-12 family. NtKRP is predominantly expressed in embryos and embryonic roots. NtKRP RNAi lines displayed reductions in cell numbers in the meristematic zone, in embryonic root length, and in mature embryo and seed sizes. Furthermore, we also show that CDKA;1 binds to NtKRP at the consensus phosphorylation sites and that the decreased cell numbers in NtKRP-silenced embryos are due to a delay in cell division cycle at the G2/M transition. In addition, binding between the cargo-binding tail domain of NtKRP and CDKA; 1 was also determined. Our results reveal a novel molecular pathway that regulates embryo/seed development and critical role of kinesin in temporal and spatial regulation of a specific issue of embryo developmental.

The relationship between collaborative marketing and customer loyalty has attracted attention in retail practice. However, in omni-channel retail, the impact mechanism of the two needs to be further defined academically. Based on the theoretical analysis of the stimulus-organism-response (SOR) framework, this paper systematically creates a research model of the impact of omni-channel collaborative marketing on new customer loyalty. It leads an empirical study using structural equation modeling with survey data from 550 agri-fresh produce omni-channel customers. The samples obtained this time is more appropriate to the overall characteristics of fresh omni-channel customers. The structural equation modeling (SEM) research model was developed on the impact of omnichannel collaborative marketing on new customer loyalty. The results show that both dimensions, i.e., price coordination and service and distribution coordination of omni-channel collaborative marketing strategy, positively affect omni-channel shopping experience and customer loyalty. Moreover, product and sales promotion coordination do not directly affect customer loyalty but through the mediating effects of the omni-channel shopping experience. Omni-channel shopping experience plays a mediating role in the relationship between omni-channel collaborative marketing and customer loyalty.

The present study tested the effects of extrinsic motivation on scientific and artistic creativity among Chinese middle school students. In Study 1, a between‐groups design was applied to examine the effects of expected rewards on scientific and artistic creativity among 123 students, and in Study 2 the same design was applied to examine the effects of expected evaluation from different raters on scientific and artistic creativity among 120 students. We also considered the effects of grade and gender in both studies. The results of Study 1 indicated that expected material reward had significant negative effects on scientific creativity for 7th graders, while expected social reward had significant positive effects on scientific creativity for 8th graders, and both expected material and social rewards had significant positive effects on artistic creativity. The results of Study 2 indicated that expected evaluation from teachers and classmates had significant negative effects on scientific creativity and significant positive effects on artistic creativity. These results suggest that there is no one‐size‐fits‐all answer to the effects of extrinsic motivation and creativity, Factors such as culture, type of extrinsic motivation, grade, and domains of creativity must be fully considered when cultivating adolescents’ creativity.

Community group-buying platforms are increasingly relying on the interaction between the group-buying leader and consumers, thereby achieving the customer lock-in. In view of this, it is crucial to understand how the group-buying leader to establish a long-term transaction relationship with consumers. In this study, we construct a model based on the role theory and trust transfer theory, and identify two types of interactions of the group-buying leader (i.e., role interaction of merchant and role interaction of friend) and two types of consumer trust (i.e., community group-buying trust and interpersonal trust). Then, the mechanism that how different role interactions of the group-buying leader can be transformed into the lock-in purchasing intention of consumers is further clarified. By interviewing 430 consumers with community group-buying experience in the community through offline questionnaire, the research model has been proven to be effective. To be specific, both role interactions of the merchant and friend can impose a positive impact on interpersonal trust, which will also lead to the trust in community group-buying, and thus enhance the lock-in purchasing intension of consumers from a fixed leader. Overall, this study has made certain contributions to the study of customer relationship. In theory, this study further explains the explanation mechanism of the “acquaintance marketing” phenomenon. Moreover, this study adopts the role theory to analyze the differences of different role interactions of the group-buying leader in relationship quality and purchase decision making, and employs the trust transfer theory to expand the trust transfer effect from the interpersonal trust of the group-buying leader to the trust in community group-buying. In practice, this study provides a new perspective and practical reference for community group-buying enterprises and the group-buying leader on how to better manage customers and maintain a long-term and stable customer relationship.

Direct interaction between NtRPL17 and the kinesin NtKRP controls cell cycle progression in plants and reveals a novel regulatory role for ribosomal proteins in seed size establishment.

The commuting cost has increased inevitably under the background of industrialization and urbanization, which has vital impacts on daily life. In this paper, we implement an empirical study to explore the impact of commuting time on hedonic consumption and the underline mechanism of perceived stress based on the data of CFPS 2014 (a national social tracking survey project). The Tobit regression combined with the Heckman two‐stage model is applied to correct the sample selection bias. The results show that the increase in commuting time will aggrandize residents' tendency and expenditure of hedonic consumption. Moreover, we conduct situational experiments as a supplement to verify the main effect and mediation mechanism to exclude alternative explanations. The mechanism analyses prove that the perceived stress caused by long commuting time is a possible mediator for hedonic consumption. This study enriches the relative studies on social influences of commute, especially proving that this social issue may provide some benefits for business practice.

Supermarkets’ cross-border integration, as an innovative format for the transformation and upgrading of traditional supermarkets, has been increasingly favored by enterprises recently. However, whether the cross-border integration of supermarkets encourages consumers to cross-buy is still a largely unexplored field. This study introduces the central and peripheral paths of the elaboration likelihood model and two mediating variables of consumers’ attitudes and herd mentality to explore the potential mechanism of consumers’ instant cross-buying intentions against the background of supermarkets’ cross-border integration. It takes consumers who purchase in cross-border integrated supermarkets as the research object. The empirical findings show that on the central path, perceived product quality and perceived fit have positive impacts on consumers’ attitudes, which then enhances their instant cross-buying intentions. Further, on the peripheral path, store image, and social interaction have positive impacts on consumers’ herd mentality, which then raises their instant cross-buying intentions.
