Abstract

Purpose

The 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/approach

The multisource and longitudinal survey data were collected from 85 teams. The authors conducted linear regression analyses to analyze the data.

Findings

The 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/implications

The research reconciles the mixed findings in prior research and enhances our understanding of the functionality of informational faultlines.

Practical implications

Team 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/value

The 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.

Abstract

Purpose

The purpose of this paper is to examine the effect of team-member exchange (TMX) differentiation on team creativity by developing a moderated mediation model. The model focuses on the mediating role of team proactivity in linking TMX differentiation with team creativity and the moderating role of leader-member exchange (LMX) median in influencing the mediation.

Design/methodology/approach

A time-lagged field survey data from 331 employees and 68 team leaders in more than ten high-technology firms from Northern China was used to test the model.

Findings

Results indicated that the negative relationship between TMX differentiation and team creativity was mediated by team proactivity. Moderated mediation analyses further revealed that team proactivity mediated the relationship between TMX differentiation and team creativity for only those teams with a low-LMX median.

Originality/value

The empirical study provides preliminary evidence of the mediating role of team proactivity in the negative relationship between TMX differentiation and team creativity. The moderated mediation model also extends the existing finding by showing that LMX quality can moderate the indirect impact of TMX differentiation on team creativity (via team proactivity).

Abstract

Purpose

Drawing on job demands and resources theory and the challenge-hindrance stressor framework, this study aims to investigate the effect of team knowledge complexity on team information sharing and information searching and examine whether team learning goal orientation mediates these effects.

Design/methodology/approach

The authors conducted two studies. Study 1 used a field survey study conducted among 374 employees positioned in 68 new product teams. Study 2 used a three-wave online survey study conducted among 208 leaders to investigate the teams they managed.

Findings

The findings of the two studies reveal that team knowledge complexity has a positive direct effect on team information sharing and information searching. Furthermore, team learning goal orientation mediates these two relationships.

Practical implications

The findings indicate that team knowledge complexity is generally beneficial for the team information process. Therefore, instead of fearing an increase in the knowledge complexity of the projects, organizations should dare to present challenge demands to team members to enhance their engagement in information processing. Organizations could also pay attention to team member selection during team composition processes. For example, selecting team members with a high level of learning goal orientation is helpful in facilitating team information processing.

Originality/value

Although previous studies have found that knowledge complexity is beneficial for team output, less is known about how knowledge complexity influences team processes. This study clarifies the relationships between team knowledge complexity, information sharing and information searching and examines team learning goal orientation as a vital mediator.

Abstract

Purpose

The authors investigate when and why a subordinate's expressive suppression facilitates workplace creativity, building on the conservation of resources theory and considering the effect of the supervisor's expressive suppression and time pressure as boundary conditions.

Design/methodology/approach

Multisource data were collected from 132 teams in northwestern China, including 132 supervisors and 648 subordinates. Hierarchical regression analyses were used to test the effects.

Findings

The subordinate’s expressive suppression was positively related to their workplace creativity. Challenge time pressure was positively related to workplace creativity, and the subordinate’s expressive suppression was positively related to workplace creativity when challenge time pressure was lower and the supervisor's expressive suppression was higher. Hindrance time pressure was negatively related to workplace creativity, and a positive relationship between a subordinate's expressive suppression and workplace creativity was also found with less hindrance time pressure and greater expressive suppression by their supervisor.

Originality/value

By examining the role of the supervisor as a source of downward spillovers in various time pressure contexts, the study explains why a subordinate’s suppression facilitates workplace creativity from the conservation of resources perspective.

Abstract

Purpose

Based on the social dominance theory, this study aims to theorize the moderating effect of power disparity in the impact of team knowledge variety on team creativity and further to verify team open communication as the mediating mechanism of the aforementioned interactive effect.

Design/methodology/approach

The multisource (team members and their team leaders) and longitudinal (separated by four months) survey data were collected from 67 research and development teams in China to test the research model. The authors used multiple regression analyses to validate all the proposed hypotheses.

Findings

Results reveal that team knowledge variety has a more positive impact on team creativity when teams have lower power disparity. Besides, team open communication is significantly and positively related to team creativity and mediates the interactive effect of team knowledge variety and team power disparity on team creativity.

Originality/value

This study reconciles the mixed findings in the previous study and provides new insights regarding the functionality of team knowledge variety. By identifying team power disparity as a moderator in shaping the effects of team knowledge variety, the authors extend the research that explores the moderators of the team knowledge variety–team creativity relationship, and make comprehensive consideration of the coexistence of multiple diversities within teams (i.e. knowledge variety and power disparity) and their joint effects on team creativity. Besides, this research identifies team open communication as an important underlying mechanism in transmitting the interactive effects of two different types of diversities on team creativity, thus offering new insights on how teams can perform creatively.

Abstract

Purpose

The purpose of this study is to empirically test and extend knowledge of the effects of emotional labor of frontline service employee.

Design/methodology/approach

The authors examined the effects of emotional labor (surface acting and deep acting) on frontline employee creativity, as well as the mediating effects of different kinds of job stress (hindrance stress and challenge stress) on the relationship between emotional labor and creativity. The research hypotheses were tested using data collected from 416 service employee–supervisor dyads in 82 Chinese local restaurants.

Findings

Results show that surface acting is negatively related to and deep acting is positively related to frontline employee creativity; surface acting is positively related to hindrance stress, while deep acting is positively related to challenge stress; and hindrance stress mediates the relationship between surface acting and creativity.

Originality/value

This study extends the consequences of emotional labor to frontline employee creativity from a cognitive perspective. It also advances knowledge about the effects of emotional labor on stress by classifying different kinds of job stress caused by different cognitive appraisals of surfacing acting and deep acting, and revealing the role of hindrance stress as psychological mechanism through which surface acting affects creativity.

Abstract

Purpose

The purpose of this paper is to recover the waste heat of flue gas heat exchanger (FGHE) as efficiently as possible and avoid the acid dew corrosion of that.

Design/methodology/approach

A novel flue gas waste heat recovery system was proposed in the paper. The dynamic mathematical models of key equipment in that were established based on theory and experiment method. The proportion integration differentiation-differentiation (PID-P) cascade control method based on particle swarm optimization algorithm was used to control the outlet temperature of FGHE. The dynamic characteristics of the flue gas heat exchange system were simulated by the particle swarm optimization algorithm with different fitness functions.

Findings

The PID-P temperature controller parameters can be quickly and effectively obtained by the particle swarm optimization algorithm based on the fitness function of integral time absolute error (ITAE). The overshoot, rise time and adjusting time of the novel system are 2, 83 and 105s, respectively. Compared with the traditional two-step tuning (T-ST) method, the novel system is better in dynamic and steady-state performance. The overshoot and the adjustment time of the system are reduced by 44% and 328s, respectively. ITAE is a performance evaluation index for control system with good engineering practicability and selectivity.

Originality/value

The dynamic mathematical model of key equipment in the new flue gas waste heat recovery system is established and the system's control strategies and methods are explored.

Abstract

Purpose

Recent literature suggests that sin firms (firms in tobacco, gambling and alcohol industries) have lower institutional ownership, fewer analysts following, higher abnormal returns and higher financial reporting quality. This study aims to investigate empirically how sin firms engage in real activities manipulation (RAM) to meet earnings benchmarks in comparison to non-sin firms.

Design/methodology/approach

The authors examine two types of RAM, namely, Cutting discretionary expenditures including research and development (R&D), SG&A and advertising to boost earnings. Extending deep discount or lenient credit terms to boost sales and/or overproducing to decrease COGS to increase gross profit. Consistent with Roychowdhury (2006), the authors use abnormal discretionary expenditures as the proxy for expenditure reduction manipulation and abnormal production costs as the proxy for COGS manipulation.

Findings

The results for the abnormal discretionary expense model suggest that sin firms do not engage in RAM of advertising, R&D, SG&A expense to just meet earnings benchmarks. The results for the production costs model suggest that sin firms do not engage in COGS manipulation to just meet earnings benchmarks. The results are robust after controlling accrual-based earnings management (AEM). Overall, in this setting, these results suggest that managers of sin firms engage less in RAM to meet earnings benchmarks.

Originality/value

The findings are of interest to investors, auditors, regulators and academics with respect to financial statement analysis and earnings quality.

Abstract

Purpose

Conventional wear models cannot satisfy the requirements of electrical contact wear simulation. Therefore, this study aims to establish a novel wear simulation model that considered the influence of thermal-stress-wear interaction to achieve high accuracy under various current conditions, especially high current.

Design/methodology/approach

The proposed electrical contact wear model was established by combining oxidation theory and the modified Archard wear model. The wear subroutine was written in FORTRAN, and adaptive mesh technology was used to update the wear depth. The simulation results were compared with the experimental results and the typically used stress-wear model. The temperature of the contact surface, distribution of the wear depth and evolution of the wear rate were analyzed.

Findings

With the increase in the current flow, the linear relationship between the wear depth and time changed to the parabola. Electrical contact wear occurred in two stages, namely, acceleration and stability stages. In the acceleration stage, the wear rate increased continuously because of the influence of material hardness reduction and oxidation loss.

Originality/value

In previous wear simulation models, the influence of multiple physical fields in friction and wear has been typically ignored. In this study, the oxidation loss during electrical contact wear was considered, and the thermo-stress-wear complete coupling method was used to analyze the wear process.
