This study aims to explore the effects of expertise diversity on project efficiency and creativity in health-care project teams.

This study analyzes hierarchical linear models using multi-source data from 50 project teams in a large health-care organization in the USA. This data set includes self-reported survey responses from 274 team members and human resource information for all 515 members across the 50 teams. Expertise diversity is operationalized by professional diversity and positional diversity reflecting two dimensions, domain and level, of the concept of expertise.

This study reveals that professional diversity is negatively related to project efficiency and project creativity, whereas positional diversity is positively related to project efficiency.

Successfully managing a project team of experts within a limited time frame is a challenge for organizations. This study advances the understanding of the double-edged sword effect of expertise diversity on project teams, focusing on professional and positional diversity. It provides important insights for human resource development in terms of the composition of project teams regarding members’ expertise.

This study investigates the relationship between leaders’ collectivist orientation and employees’ innovative behavior, as well as the mediating effects of employees’ collectivist orientation and servant leadership.

Based on a survey of 40 leaders and 219 employees in 12 technologically innovative enterprises in Jiangsu Province, China, a hierarchical linear modeling is used.

The results show that leaders’ collectivist orientation significantly positively affects employees’ innovative behavior. Moreover, leaders’ collectivist orientation significantly positively affects employees’ collectivist orientation/servant leadership, employees’ collectivist orientation/servant leadership significantly positively affects employees’ innovative behavior, and employees’ collectivist orientation/servant leadership partially mediates the relationship between leaders’ collectivist orientation and employees’ innovative behavior.

In response to the lack of research on the relationship between leadership cultural orientation and employees’ innovative behavior, this study sheds light on the effectiveness and mechanism of the influence of leaders’ collectivist orientation on employees’ innovative behavior, thus expanding and deepening the boundaries of theoretical research on leadership, culture and innovation management.

The rise of communication software has changed our work style. The objectives of this study are: (1) to explore the effect of supervisors making after-hours work requests using communication software (SWRUCS) on employees’ job stress, quality of life and (2) to examine the moderating effect of personality traits and the cross-level contextual effect of social support.

A questionnaire survey was conducted to obtain information from 357 employees.

The results suggested that SWRUCS exacerbated job stress, which negatively impacted on quality of life and well-being. Moreover, different personality traits can either increase or decrease the positive or negative effect of SWRUCS on job stress. This study also revealed that social support can reduce employees’ job stress in a cross-level fashion. Furthermore, social support, especially organizational and supervisory support, can decrease the negative effect of job stress on employees’ quality of life and well-being.

Theoretically, this study has broadened the research scope of the organizational application of communication software, and practically, this study has demonstrated the reason why organizations should provide social support and select employees with suitable personality traits.

Sailing toward sustainability is becoming the strategic focus of shipping firms. Drawing on organizational information processing theory (OIPT) and the theory of planned behavior (TPB), we investigated the impact of digital transformation (DT) on shipping firms’ sustainable management performance and the boundary conditions guiding this relationship.

The authors examined the hypotheses by employing hierarchical linear modeling on two-wave time-lagged data from 189 shipping firm employees in China.

The results suggest that a shipping firm’s DT is positively associated with its sustainable management performance and that the relationship is strengthened by having better cross-functional and customer coordination mechanisms. Furthermore, our three-way interaction analyses show that while injunctive norms in a shipping firm’s networks can strengthen the contingency roles of both cross-functional and customer coordination mechanisms, descriptive norms alone significantly influence customer coordination.

Drawing on organizational information processing and planned behavior theories, the present research provides new insights into leveraging DT for sailing toward sustainable success. Moreover, this study extends the current understandings of the boundary conditions of the relationship between DT and sustainable management performance by showing the two-way and three-way interaction effects of coordination mechanisms and subjective norms. The findings of the present research can be utilized as effective strategies for promoting sustainable management performance.

Drawing upon the conservation of resources (COR) theory, this study examined the relationship between organizational developmental human resource (HR) practices and employees' commitment to the organizational career (COC), while considering the mediating role of psychological availability and the moderating effects of links and fit.

A hierarchical linear modeling analysis was conducted to analyze the data from a 3-wave time-lagged study with 394 employees and 65 supervisors in ten Chinese firms.

The study's findings suggest that organizational developmental HR practices have a positive and indirect impact on employees' COC, with psychological availability serving as a mediator. The indirect effects were stronger for employees with stronger links and better fit.

This study provides managers with guidelines to improve employees' COC. Managers should also focus on supporting employees' psychological resources. Furthermore, organizations should be aware that employees with varying levels of links and fit may respond differently to psychological availability.

The study offers a new understanding of how and under what conditions organizational developmental HR practices can increase employees' COC. It also highlights the role of psychological availability as the psychological mechanism mediating this relationship and adds to the limited literature on the potential positive impact of strong links and fit.

The effects of ownership concentration on firm performance usually considers two conflicting perspectives: monitoring and expropriation hypotheses. Past studies have produced mix findings. This study aims to shed light on this relationship by focusing on a specific measure of firm performance, firm growth. The moderating effect of industry growth in the aforementioned relationship is also considered, which advances knowledge on the role of moderators.

This study resorts to data from a sample of 21,476 Portuguese firms, which is examined using hierarchical linear modelling. This approach is adequate because the data has a hierarchical structure: the firms are nested within industries.

The results show that equity ownership concentration has a positive effect on firms’ growth and that industry growth amplifies this relationship. Ownership concentration can spur effective monitoring, thereby alleviating principal–agent conflicts of interest and speeding up decision-making, enabling timely competitive actions that promote growth.

The research conceives ownership structure in two groups. However, equity ownership concentration often acquires more complex shapes. In addition, the data used is from a single country.

The results show that firms pursuing growing strategies and operating in growing industries benefit from equity concentration.

Different from past studies, this study focuses on firm growth performance and considers the moderating effect of industry growth.

Village health volunteers are community health volunteers in Thailand that have helped the government deliver public health services for many years, particularly during the coronavirus disease 2019 (COVID-19) pandemic. Though labeled as “volunteers,” the village health volunteers are recruited, trained and supervised in a manner similar to how a government agency recruits, trains and supervises its street-level bureaucrats (SLBs). This study examines the two factors that affect how these street-level quasi-bureaucrats use their professional discretion: transformational leadership and public service motivation (PSM). Transformational leadership means a leadership style that develops, shares and sustains a vision to elevate SLBs to higher levels of performance, while PSM is defined as an SLB’s predisposition to make a difference by working in the public sector with a sense of calling. This study attempts to analyze the mediating role of psychological empowerment in the relationship between transformational leadership, PSM and professional discretion.

The paper uses a three-wave survey-based quantitative method to avoid common method biases. This method provides evidence gathered from 105 subdistrict health promotion hospitals and 798 village health volunteers (VHVs) in five provinces in Thailand.

PSM and transformational leadership influence the village health volunteers' use of professional discretion indirectly through the psychological empowerment mechanisms that make them feel positive toward their village health volunteer role and responsibility. The authors' findings suggest that the hospital directors' transformational leadership induces the village health volunteers' use of professional discretion by making them feel competent to do their work and feel fulfilled and valuable about their work. Similarly, the village health volunteers' PSM leads them to use professional discretion by making them feel fulfilled and valuable and by convincing them of the social and community impact of their work.

While existing research focuses on VHVs' role in alleviating capacity constraints on the health care system, this study revealed an equally important role played by hospital directors. These directors' transformational leadership was instrumental in enhancing VHVs' psychological empowerment – particularly their perceptions of the meaning of their work and their competence – that ultimately enabled them to use professional discretion in their work. This study also highlighted the importance of VHVs' PSM, which leads to their use of professional discretion via the meaning and impact dimensions of psychological empowerment. Based on this study, PSM should also be incorporated into the community health volunteers' recruitment criteria. Also, public health agencies should consider including transformational leadership in the hospital directors' training programs and their promotion criteria.

As VHVs' high-PSM level was found to enhance their professional discretion, the process of recruiting ordinary citizens to serve as community health volunteers should incorporate assessment of the candidates' PSM. Also, the Ministry of Public Health should design and assign tasks that citizen volunteers, particularly VHVs, consider meaningful and at which they feel competent.

Aside from technical training, directors of the subdistrict health promotion hospitals should regularly receive soft skill training (i.e. leadership training) and transformational leadership characteristics should be included in the government criteria for promotion.

While past research has examined the impact of other leadership styles on psychological empowerment, this study took a further step by examining the mediating effects of psychological empowerment on the relationship between transformational leadership and professional discretion among VHVs. The authors analyzed the mechanism linking PSM to the VHVs' professional discretion. In addition, by examining the relative importance of different dimensions of psychological empowerment, this study offers a nuanced understanding of the psychological processes by which transformational leadership and PSM shape the SLBs' use of professional discretion in their work.

This study aims to investigate how message sidedness affects the impact of fake news posted on social media on consumers' emotional responses.

The study involves a face-tracking experiment in which 198 participants were exposed to different fake news messages concerning the COVID-19 vaccine. Specifically, participants were exposed to fake news using (1) a one-sided negative fake news message in which the message was entirely unfavorable and (2) a two-sided fake news message in which the negative message was mixed with favorable information. Noldus FaceReader 7, an automatic facial expression recognition system, was used to recognize participants' emotions as they read fake news. The authors sampled 17,450 observations of participants' emotional responses.

The results provide evidence of the significant influence of message sidedness on consumers' emotional valence and arousal. Specifically, two-sided fake news positively influences emotional valence, while one-sided fake news positively influences emotional arousal.

The current study demonstrates that research on fake news posted on social media may particularly benefit from insights regarding the potential but often overlooked importance of strategic design choices in fake news messages and their impact on consumers' emotional responses.

The purpose of this paper is to investigate the mediating roles of tacit and explicit knowledge sharing (KS) in linking the relationship between knowledge-based HRM practices and innovation competence of firms. This study also explores the potential moderating role of market turbulence in fostering the influence of KS behaviors on two forms of innovation competence namely radical innovation and incremental innovation.

The paper applied the quantitative approach and structural equation modeling to examine the correlation among the latent constructs based on the survey data collected from 293 participants in 115 firms.

The empirical findings of this study support the mediating role of KS behaviors in the relationship between knowledge-based HRM practices and aspects of innovation competence. It highlights the important role of market turbulence in stimulating the influence of KS behaviors on innovation capabilities.

Future research should investigate the impact of knowledge-based HRM practices on innovation capability via the mediating effects of knowledge management processes to bring better understanding of the importance of knowledge resources in organizations.

The paper significantly contributes to increasing knowledge and insights into the antecedent role of knowledge-based HRM practices, the mediating role of KS behaviors as well as the moderating role of market turbulence in fostering radical and incremental innovation, thereby advancing the body of comprehension of knowledge-based resources and innovation theory.

This study aims to investigate the effects of entrepreneurial leadership on service innovation in the hospitality industry and examine the mediating effects of market-sensing capability and knowledge acquisition. Additionally, the study explores the moderating role of competitive intensity in the relationships between market-sensing capability, knowledge acquisition and service innovation, drawing on the dynamic capability theory and resource dependence theory.

The data for this study were obtained from 322 employees and 137 leaders working in 103 hotels in Vietnam, using a time-lagged approach. The collected data were analyzed using structural equation modeling in SPSS Amos 28.

The results of this study reveal a significant positive association between entrepreneurial leadership and service innovation, with mediation effects observed through both knowledge acquisition and market-sensing capability. Moreover, the findings demonstrate that competitive intensity moderates the association between knowledge acquisition and service innovation.

The results of this study provide implications for hospitality firms to cultivate entrepreneurial leadership through leadership training and development programs and enhance their dynamic capabilities (i.e. market-sensing capability and knowledge acquisition) to allow them to survive and develop in a competitive market.

This study advances entrepreneurial leadership research in the hospitality context by identifying mediating and moderating mechanisms that translate entrepreneurial leadership into hospitality firms’ service innovation.
