Supportive supervisor behavior and helping behaviors in the hotel sector: assessing the mediating effect of employee engagement and moderating influence of perceived organizational obstruction.

While emerging studies pay much attention to the supervisory support-employee performance relationship, the supportive supervisor consequences on employees' attitudes and behaviors have attracted little attention in this relationship. In spite of the growing concern about employees' helping behaviors as a tool that directly benefit coworkers to be work-role focused and improve performance, supportive supervisor behavior that represents the psychological, physical, cognitive, and esteem assistance has also been deemed to be a catalyst of employees' helping behaviors. Also, it is worth noting that employees exhibit helping behaviors when they are highly engaged in work role focus, activation, and positive affect. However, little has been espoused on how supportive behaviors could enhance employees' loyalty to spark helping behaviors. Owing to this narrative, this study draws on social exchange theory and reciprocity norm to examine the mediating role of employee engagement in the effects of supportive supervisor behavior on hotel employees' helping behaviors. Also, this study examined the boundary role of perceived organizational obstruction based on perceived organizational support as proposed by organizational support theory. Using a time lag of six months, a two-wave data were gathered from 461 full‒time frontline employees working in 3-5 star hotels in Ghana. Hierarchical regression was used to analyze the hypothesized relationships. The results demonstrated that supportive supervisor behavior positively related to employees' helping behaviors. Besides, intellectual, social, and affective engagement partly mediated the relationship between supportive manager behavior and employees' helping behavior. Moreover, perceived organizational obstruction moderated the relationship between intellectual engagement and employees' helping behavior. However, failed to moderate social and affective engagement relationships with employees' helping behaviors.

The role of bank financing in economic growth and environmental outcomes of sub-Saharan Africa: evidence from novel quantile regression and panel vector autoregressive models.

In sub-Saharan Africa, economic expansion and its environmental implications have become major problems. The banking system has been described as a mechanism for decoupling economic expansion from environmental implications. However, the function of bank financing in the growth-environmental consequences in SSA remains undeveloped. This study investigated the role of bank financing in economic growth and environmental outcomes in SSA over the period 1990-2018. We implemented the novel panel quantile regression and panel vector autoregressive models in a generalized method of moments' framework to investigate the influence of bank financing on economic growth and carbon emissions, and the moderating effect of bank financing in growth-environmental consequences among the four regional economies in SSA. The empirical results revealed that bank financing (1) increases economic growth and carbon emissions across quantiles; (2) positively influences economic growth and carbon emissions of East and Central African regions but negatively influences economic growth and carbon emissions of the West African region; (3) mitigates growth-emissions outcomes of low-emission countries but worsens growth-emissions outcomes of median and high emission countries; and (4) worsens growth-emissions outcomes of East and Central African regions but mitigates growth-emissions outcomes of Southern and West African sub-regions. The variance decomposition and impulse response results discovered that the role of bank financing in growth-environmental challenges varies in terms of magnitude and elasticities across the sub-regions over the sampled period. The study also revealed mixed findings regarding the existence of the EKC hypothesis for the sub-regional economies in SSA.

Investigating the Effects of Role Demands, Psychosocial Stress Symptoms and Safety Leadership on Mineworkers' Safety Performance.

PURPOSE: This study aimed to investigate the effects of role demands on safety performance in mining companies under the mediating role of psychosocial stress symptoms. Three dimensions of safety leadership were also tested as moderators on the relationship between psychosocial stress symptoms and safety performance. METHODS: To collect data to analyze the hypothesized relationships in the present study, a total of 850 questionnaires were distributed to mineworkers in Ghana. Hierarchical regression analysis was employed as the main statistical technique in analyzing the data using SPSS version 21 software. FINDINGS: Results from hierarchical regression analysis showed that psychosocial stress symptoms fully mediated the relationship between role demands and safety compliance but showed no mediation on role demands and safety participation. Also, only safety coaching from safety leadership demonstrated to have a moderating effect on the relationship between psychosocial stress symptoms and safety compliance of safety performance. CONCLUSION: The study proposes that it is important to examine the effects of role demands on specific job performance. The importance of safety coaching as a key element of planning to improve safety performance should not be underestimated.
