The purpose of this study was to investigate the relationships between perceived coaching behavior (autonomy-supportive and controlling), communication, coach–athlete relationship, and athlete burnout. The study participants comprised 347 Korean active collegiate athletes from 10 sports. The results of the final model indicated that autonomy-supportive coaching was positively related to communication, whereas controlling coaching was negatively related to communication. Communication was positively related to coach–athlete relationship and was negatively related to athlete burnout. Autonomy-supportive coaching was significantly related to both the coach–athlete relationship (positively) and athlete burnout (negatively), whereas controlling coaching was only related to athlete burnout (positively). Coach–athlete relationship was negatively related to athlete burnout. Significant indirect effects were observed. The bootstrapping results indicated that the relationship between autonomy-supportive and athlete burnout was mediated by team communication and the coach–athlete relationship. The study findings enhance our current understanding of the relationships between perceived coaching behavior and athlete burnout and shed light on the important roles of team communication and the coach–athlete relationship in the relationship.

Objectives: Athlete burnout is a crucial concern affecting the development and athletic performance of young weightlifters. To reduce or relieve the prevalence of athlete burnout, this study examined the relationship across social support, sports motivation, mental toughness, and athlete burnout in weightlifters.Methods: A total of 315 weightlifters aged 17–28 years old (151 males, 164 females; Mage = 18.89 years, SD = 3.66) from Sichuan, Chongqing, and Shanxi in China participated in this survey. The Perceived Available Support in Sport Questionnaire (PASS-Q), Sports Motivation Questionnaire (SMQ), Sports Mental Toughness Questionnaire (SMTQ), and Athlete Burnout Questionnaire (ABQ) were used in this study. SPSS Statistics 19.0, AMOS 21.0, and PROCESS 3.0 macro were used to analyze the collected data.Results: The results indicated that weightlifters’ social support could negatively significantly affect athlete burnout [beta = −0.398; 95% confidence interval (CI): −0.3699, −0.2184; P < 0.05) via mental toughness and sports motivation. The mediation analysis revealed that they had partial mediating effect, including three paths: First, social support had a direct effect on athlete burnout (beta = −0.150; 95% CI: −0.1824, −0.0397; P < 0.05); second, sport mental toughness had a mediating effect on athlete burnout (beta = −0.113; 95% CI: −0.1703, −0.0631; P < 0.05); and finally, sports motivation had a mediating effect on athlete burnout (beta = −0.124; 95% CI: −0.1751, −0.0793; P < 0.05).Conclusion: The findings revealed that social support could inhibit or prevent athlete burnout via mental toughness and sports motivation; thus, to decrease or relieve the prevalence of burnout in weightlifters, it is an important solution to enhance their social support.

Purpose The purpose of this paper is fourfold: first, to investigate the effect of team diversity on different types of conflicts; second, to determine if team diversity is significantly correlated with project performance; third, to investigate the mediating effect of project conflicts on the relationship between team diversity and project performance and fourth, to examine the relationship between different types of conflicts and project performance in construction projects. Design/methodology/approach A theoretical model was developed and a questionnaire survey was conducted with 246 professionals. The structural equation modeling technique was applied to analyze the data. Findings The results showed that: team diversity was positively associated with project performance; the introduction of conflicts significantly weakened the effect of diversity on performance; conflicts have both constructive and destructive effects on project performance; and team diversity affected project performance through the mediating effects of task conflict and relationship conflict, thus adding both positive and negative effects on performance. Research limitations/implications There are other factors which may affect conflicts and project performance such as communication, trust and contract. Future research could be conducted to determine the role of these variables in determining the effects of team diversity on performance. Practical implications It is necessary to reduce the relationship conflict whereas maintaining a “healthy” level of task conflict. In light of this, the conclusions of this study highlight practical implications as follows: project teams should attach importance to diverse partner selection and select cooperative partners whose value orientations are similar; when implementing a construction project, the structure of diverse project teams should keep relatively stable, avoiding too many teams entering or exiting the project in a short period; project teams should make greater efforts to deal with destructive conflicts via relational governance such as trust and communication. Originality/value This study contributes to the literature in three areas. First, this study investigated the dynamic mechanism between team diversity, conflicts and performance in construction projects. Second, this study contributes to the body of knowledge on validating the mediating effects of conflicts on the relationship between team diversity and performance. Third, this study validated the positive and negative effects of team diversity on performance with different types of conflicts as mediation variables in construction projects.

Positive Effect

Previous theoretical research has indicated that hope, cognitive reappraisal, and acceptance may contribute to posttraumatic growth (PTG). However, the combined effects of these factors on PTG have not yet been evaluated. Therefore, the current study examined the mediating roles of cognitive reappraisal and acceptance in the relationship between hope and PTG among Chinese adolescents following the Ya'an earthquake. The sample included 397 adolescent survivors, who completed self-report measures 2.5 years after the earthquake. The mediating effects were assessed by constructing a multiple indirect effects model. The findings indicated that traumatic exposure only have predictive value for PTG, but not other variables. Moreover, when we controlled for gender, age, and traumatic exposure, hope had a direct and positive effect on PTG. We found an indirect and positive effect of hope on PTG via cognitive reappraisal and acceptance, as well as via an indirect path from cognitive reappraisal to acceptance. These findings suggest that utilising the mediating roles of cognitive reappraisal and acceptance in the relationship between hope and PTG is crucial in developing methods for fostering PTG.

This study further specifies the relationship between injury, self-conceptions, and depression. With the use of path analysis, we look at the direct and indirect effects of pain and work limitation associated with a job-related injury on self-efficacy, self-esteem and depression for a sample of injured workers (N = 1,037). As expected, we found that self-efficacy and self-esteem are negatively associated with depression, while work limitation and pain are positively associated with depression. We also found that work limitation has additional indirect effects on depression through its effect on self-efficacy and self-esteem. Pain has an additional indirect effect on depression via its effect on self-efficacy and work limitation. These findings support our expectation that self-concept significantly mediates the relationship between physical injury and depression.

PurposeThe purpose of this paper is to examine the effect of agile manufacturing (AM) on business performance and operational performance (OP) dimensions in manufacturing companies in Jordan. It also explores the indirect effect of AM on business performance through OP dimensions of cost, quality, delivery and flexibility.Design/methodology/approachThe study analyzes survey data collected from 282 manufacturing companies from different industries in Jordan. Validity and reliability analyses were performed using SPSS and Amos, and the research hypotheses were tested using structural equation modeling.FindingsThe results demonstrated that AM positively and directly affected business performance. It also positively affected OP dimensions of quality, delivery and flexibility. However, cost performance was not significantly affected by AM. In addition, quality performance and flexibility performance fully mediated the relationship between AM and business performance, whereas cost performance and delivery performance did not show mediating effects.Originality/valueTo the best of the knowledge, this is the first study that investigates the mediating effects of OP dimensions on the relationship between AM and business performance. In addition, a limited number of previous studies investigated the performance outcomes of AM. Furthermore, this area is under-investigated in the Middle East in general and in Jordan in particular.

Grounded in Lazarus’s (1991, 1999, 2000) cognitive-motivational-relational theory of emotions, we tested a model of achievement goals, stress appraisals, emotions, and coping. We predicted that precompetitive achievement goals would be associated with appraisals, appraisals with emotions, and emotions with coping in our model. The mediating effects of emotions among the overall sample of 827 athletes and two stratified random subsamples were also explored. The results of this study support our proposed model in the overall sample and the stratified subsamples. Further, emotion mediated the relationship between appraisal and coping. Mediation analyses revealed that there were indirect effects of pleasant and unpleasant emotions, which indicates the importance of examining multiple emotions to reveal a more accurate representation of the overall stress process. Our findings indicate that both appraisals and emotions are just as important in shaping coping.
