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.

A transition to a more sustainable society is occurring worldwide and necessitates a change in people's ways of consuming. Self-transcendence (ST) is recognized as a key predictor of green consumption. Thus, a multiple intermediary model was developed to clarify the psychological mechanisms underlying ST and its influence on consumption. The model was tested using data from a nationally representative sample of 428 Chinese participants. The results show that ST's overall positive effect on green consumption is realized via four indirect paths: (1) the simple mediating role of nature connectedness between ST and green consumption, (2) the simple mediating role of social connectedness between ST and green consumption; (3) the chain-mediating role of construction of meaning in life (CoMIL) and nature connectedness, and (4) the chain-mediating role of CoMIL and social connectedness. Among these paths, nature connectedness plays the most critical mediating role for the Chinese, accounting for the greatest proportion of the total indirect effect. The study advances understanding of the influence and path of ST on green consumption, and provides theoretical and practical support for guiding people toward sustainable lifestyles.

Customer engagement is a new value index affecting the omnichannel benefits of enterprises. It is beginning to attract the attention of both scholars and managers. However, there is still a lack of research on the mechanism influencing customer engagement in the fresh food omnichannel retail context. Drawing from the stimulus–organism–response (SOR) framework, this paper builds a relationship model between omnichannel integration and fresh food customer engagement. In addition, the paper empirically analyzes the mechanism of omnichannel integration’s impact on fresh food customer engagement. The findings show that omnichannel integration promotes flow experiences through three modes: information integration, business integration, and service and distribution integration. Flow experience is mediating the relationship between omnichannel integration and customer engagement. Strengthening the customer engagement knowledge system can help fresh food omnichannel retailers to create and manage the long-term cooperative relationship between customers and the company’s value creation. The higher the degree of omnichannel integration of fresh food retail firms, the more conducive it is to enhancing the customer flow experience, which will positively impact customers’ attitudinal and behavioral engagement.

With an expanding consumer base for organic food globally and a steadily growing interest worldwide, it is important to understand the influencing factors behind organic food preference formation and purchasing decisions. Distinguishing from previous studies, this study focuses on the conspicuousness of organic food consumption and proposes a new concept of conspicuous organic food consumption. This study aims to explore the relationship between social crowding, the need for self-expression, and conspicuous organic food consumption. Through three experimental studies, this study reveals that: (1) social crowding positively influences the consumption of conspicuous organic foods, (2) the need for self-expression plays a mediating role, and (3) self-concept clarity plays a moderating role. Specifically speaking, the conspicuousness leads consumers to increase their choice of organic food under social crowding, with the need for self-expression playing a fully mediating role in this effect. However, this effect only exists among consumers with lower levels of self-concept clarity; when consumers have higher levels of self-concept clarity, the influence of social crowding and non-social crowding on conspicuous organic food consumption does not significantly differ. By highlighting the uniqueness and usefulness of social crowding as an environmental factor, this study can facilitate companies to adjust their organic food marketing strategies to different levels of crowding promptly, thereby expanding organic food consumption.
