Estimation and sensitivity analysis for causal decomposition in health disparity research

In the field of disparities research, there has been growing interest in developing a counterfactual-based decomposition analysis to identify underlying mediating mechanisms that help reduce disparities in populations. Despite rapid development in the area, most prior studies have been limited to regression-based methods, undermining the possibility of addressing complex models with multiple mediators and/or heterogeneous effects. We propose a novel estimation method that effectively addresses complex models. Moreover, we develop a sensitivity analysis for possible violations of an identification assumption. The proposed method and sensitivity analysis are demonstrated with data from the Midlife Development in the US study to investigate the degree to which disparities in cardiovascular health at the intersection of race and gender would be reduced if the distributions of education and perceived discrimination were the same across intersectional groups.

Leadership and Follower Voice: The Role of Inclusive Leadership and Group Faultlines in Promoting Collective Voice Behavior

We developed and tested a theoretical model to examine how and when inclusive leadership affected collective voice behavior in this study. We identified two voice-relevant mediators—group psychological safety (an emergent state) and information elaboration (a group process) to clarify the mechanisms between inclusive leadership and collective voice behavior. Further, according to the person–situation interaction approach, we brought the faultlines theory to the inclusive leadership literature and considered group faultlines as a positive moderator to maximize the effects of inclusive leadership. With a two-wave, two-source design, we collected data from 301 employees within 67 research and development groups in China. We found that inclusive leadership positively affected collective voice behavior through the mediating mechanisms of both group psychological safety and information elaboration. Additionally, this effect was stronger in high faultlines situation. The findings suggest that leaders should show inclusiveness to motivate collective voice, especially in groups with high faultlines.

Individual Experience and Engagement in Avatar-Mediated Environments: The Mediating Effect of Interpersonal Attraction

The application of different virtual reality interventions has been recently gaining interest from researchers and practitioners. Due to the current COVID-19 pandemic, higher education institutions increased the use of these technologies to help create much value for educators and students. The relationship between individual experience and engagement in avatar-mediated environments has garnered empirical support, but still little is known about the mediating mechanisms underlying this relation. This study investigated the mediating role of interpersonal attraction (e.g., social, physical, and task attraction) in the link between individual experience and engagement in an avatar-mediated learning environment. A total of 112 participants (21–23 years; 73 male and 39 female) participated in online peer learning sessions in Second Life. After controlling for demographic covariates, the results showed that (1) individual experience was positively associated with students’ engagement; (2) social, physical, and task attraction was found to positively mediate the link between experience and engagement. The outcomes from this study provide valuable implications for promoting online learners’ engagement in avatar-mediated environments.

Employee high-performance work systems-experience attributions of well-being and exploitation: a multilevel study of Greek workplaces

PurposeThis paper aims to theoretically propose and empirically test a research framework that investigates the relationship between high-performance work systems (HPWSs) and organizational performance through the serially mediating mechanisms of employee HPWS-experience attributions of well-being and exploitation, attitudes, and behaviors.Design/methodology/approachMultilevel structural equation modeling through Mplus was applied to a sample of 1,112 employees working at 158 Greek organizations.FindingsThe modeling's findings indicate that the serially mediating mechanism of employee HPWS-experience attributions of well-being, attitudes and behaviors improves organizational performance. Meanwhile, the serially mediating mechanism of employee HPWS-experience attributions of exploitation, attitudes and behaviors was found to weaken organizational performance.Practical implicationsThis study shows that, to improve employees' well-being and weaken employee exploitation through employees' HPWS-experience attributions, senior and line managers should gain competencies and communication skills through training and development programs, successfully communicating HPWS messages to employees.Originality/valueThis study may be the first study to elucidate the serially mediating mechanisms of employees' well-being and exploitation through employees' HPWS-experience attributions, attitudes and behaviors in the relationship between HPWSs and organizational performance.

Community Participation and Subjective Wellbeing: Mediating Roles of Basic Psychological Needs Among Chinese Retirees

Objectives: Participation in various social organizations, including community organizations, has become an important part of later year. The current study examined the effects of community participation on subjective wellbeing (SWB) and mediating mechanisms among retired residents. Specifically, this study attempts to explain the link between community participation and SWB from the perspective of basic psychological needs (BPN).Methods: A total of 1,458 community-dwelling retirees aged ≥50years in China participated in this study. A self-developed questionnaire measured the general levels of community participation. BPN were assessed with the BPN Scale. SWB was represented by life satisfaction, positive affect, and negative affect.Results: Community participation positively predicted one’s SWB. Specifically, retirees with a higher levels of community participation often indicated higher life satisfaction and positive affect, and lower negative affect. Three BPN, which consist of needs for autonomy, competence, and relatedness, mediated the effect of community participation on SWB, respectively, after controlling for some main demographic and socioeconomic factors.Conclusion: The BPN perspective provides a comprehensive explanation for understanding the link between community participation and SWB. Policymakers should consider the role of community participation when developing measures to improve retirees’ quality of life.

How Leader Narcissism Links to Team Voice Behavior: The Mediating Mechanisms of Leader Voice Solicitation and Team Voice Climate

Drawing on the narcissism literature and social information processing theory, we theorized and examined a serial mediation model linking leader narcissism with team voice behavior through leader voice solicitation and team voice climate. We tested our hypotheses using data collected from a time-lagged and multisource survey of 223 frontline employees in 60 teams at a large manufacturing organization. The results indicated that leader narcissism had a negatively indirect effect on team voice climate via leader voice solicitation. Team voice climate positively predicted team voice behavior, and the indirect effects of leader narcissism via leader voice solicitation and team voice climate on team voice behavior were significantly negative. In this paper, we discuss the theoretical implications of our findings for both the narcissism literature and the voice literature, along with their practical implications.

EXPRESS: Where are the entrepreneurs? A call to theorize the micro-foundations and strategic organization of entrepreneurial ecosystems

The “entrepreneurial ecosystem” (EE) has become the dominant metaphor in theories explaining how location-specific forces influence entrepreneurship. Despite the progress made by scholars studying EEs, in this essay we contend that the ecosystem metaphor has created an implicit tendency in entrepreneurship theory to emphasize macro-, ecosystem-level dynamics rather than the causal and mediating mechanisms linking entrepreneurs and their local ecosystems. To accompany the macro-dynamics focus in EE theory, we call for a micro-foundations approach that emphasizes the bi-directional connections between entrepreneurs’ strategizing and organizing activities and their ecosystems. We offer an agenda of theory development opportunities at the intersection of strategic organization and EEs.

Research on Mediating Mechanisms and the Impact on Food Provision Services in Poor Areas from the Perspective of Stakeholders

Exploring and analyzing the common demands and behavioral responses of different stakeholders is important for revealing the mediating mechanisms of ecosystem service (ES) and realizing the management and sustainable supply of ES. This study took Mizhi County, a poverty-stricken area on the Loess Plateau in China, as an example. First, the main stakeholders, common demands, and behavioral responses in the food provision services were identified. Second, the relationship among stakeholders was analyzed. Finally, this study summarized three types of mediating mechanisms of food provision services and analyzed the influence of the different types of mediating mechanisms. The main conclusions are as follows: (1) Five main stakeholders in the study area were identified: government, farmers, enterprises, cooperatives, and middlemen. (2) Increasing farmers’ income is the common demand of most stakeholders in the study area, and this common demand has different effects on the behavioral responses of different stakeholders. (3) There are three types of mediating mechanisms in the study area: government + farmers mediating corn and mutton, government + enterprises mediating millet, and government + cooperatives mediating apples. On this basis, the effects of the different types of mediating mechanisms on variations in food yield, and trade-offs and synergies in typical townships, were analyzed.
