Despite an increasing number of studies on leader humility, the relationship between leader humility and team creativity needs further exploration. Using the connectionist network model, we propose that leader–leader exchange (LLX), the upward exchange relationship of a team's direct supervisor, moderates the effect of leader humility on team job crafting, and this in turn affects team creativity. We test our hypotheses using a sample of 286 employees in 59 teams with a multiple‐source, time‐lagged research design. Our conclusions are as follows: (a) for team leaders with high LLX, leader humility is positively related to team job crafting, whereas for team leaders with low LLX, the relationship between leader humility and team job crafting is negative; (b) team job crafting is positively related to team creativity and (c) team job crafting mediates the effect of the interaction between leader humility and LLX on team creativity.

As a multinational country incorporating 56 officially recognized ethnic groups, China is concerned with the mental health of members of minority ethnic groups, with an increasing focus on supporting Chinese ethnic minority college students. Nevertheless, in daily life, members of minority ethnic groups in China often perceive prejudice, which may in turn negatively influence their mental health, with respect to relative levels of ethnic identity and hope. To examine the mediating effects of ethnic identity and hope on the relationship between perceived prejudice and the mental health of Chinese ethnic minority college students, 665 students (18–26 years old; 207 males, 458 females; the proportion of participants is 95.38%) from nine colleges in the Guangxi Zhuang autonomous region and Yunnan and Guizhou provinces of China took part in our study, each completing adapted versions of a perceived prejudice scale, a multiethnic identity measure, an adult dispositional hope scale, and a general health questionnaire. Analysis of the results reveals that perceived prejudice negatively influences mental health through both ethnic identity and hope in Chinese ethnic minority college students. The total mediation effect was 54.9%. Perceived prejudice was found to negatively predict ethnic identity and hope, suggesting that perceived prejudice brings about a negative reconstruction of ethnic identity and hope mechanisms within the study's Chinese cultural context. The relationship between perceived prejudice and mental health was fully mediated by hope and the chain of ethnic identity and hope. Ethnic identity partially mediated the relationship between perceived prejudice and hope. The relationship between perceived prejudice and mental health mediated by ethnic identity was not significant, which suggests that the rejection–identification model cannot be applied to Chinese ethnic minority college students. This paper concludes by considering the limitations of our study and discussing the implications of its results for researchers and practitioners.

PurposeThe purpose of this paper is to examine the curvilinear relationship between team informational faultlines and team creativity and the moderating effects of team humble leadership on the relationship.Design/methodology/approachThe multisource and longitudinal survey data were collected from 85 teams. The authors conducted linear regression analyses to analyze the data.FindingsThe results indicate that the relationship between team informational faultlines and team creativity is inverted U-shaped and such relationship is stronger in teams with low levels of humble leadership.Research limitations/implicationsThe research reconciles the mixed findings in prior research and enhances our understanding of the functionality of informational faultlines.Practical implicationsTeam managers should seek optimal levels of informational faultlines and make diversity coexist with similarity when assembling a new working group so as to utilize the benefits of team composition diversity and fuel collective creativity. Team leaders should learn humble leadership skills to encourage open communication.Originality/valueThe research is the first to adopt and build on the social information processing (SIP) perspective to explain the curvilinear relationship between team informational faultlines and team creativity.

In China, aging is becoming an increasingly serious issue, and the Chinese government are paying more attention to the life satisfaction of the elderly. Nevertheless, in their daily lives, the elderly are often discriminated against, which may have a negative impact on their life satisfaction. To enable a better understanding of these relationships, we discuss the factors affecting the macro-system (national identity) and micro-system (sense of community) of the elderly. Three hundred and ninety-one elderly people (60–101 years old; 121 males, 270 females) from three communities in the Anhui and Shandong provinces of China participated in our study. Each participant completed the appropriate questionnaires, including: perceived discrimination measure, national identity questionnaire, sense of community questionnaire, and life satisfaction questionnaire. The results of structural equation modeling revealed that perceived discrimination negatively influenced life satisfaction through national identity and community. Perceived discrimination was found to negatively predict national identity, suggesting that perceived discrimination brings a negative influence to national identity within Chinese culture. The relationship between perceived discrimination and life satisfaction was partially mediated by the chain of national identity and sense of community. The size of the total mediation effect was 32.17%. The relationship between perceived discrimination and life satisfaction, when mediated by national identity or sense of community, was not significant. This suggests that the application of the rejection-identification model to the elderly in China may produce different results. The limitations and the implications of our study were considered in discussion.
