Social exchange theory is used in this paper to explore how the quality of leader–member exchange (LMX) and perceived organizational support (POS) affect Brazilian nursing professionals’ perceptions of bullying and harassment and, in turn, their wellbeing. Data was obtained from 868 nursing professionals in four public hospitals in Brazil. Statistically significant linkages were found between L...

Lepidopteran insect pests are the main class of pests causing significant damage to crop plant yields. Insecticidal scorpion peptides exhibit toxicity specific for insects. Here, we report that a peptide LMX, optimized from the insect-specific scorpion neurotoxin LqhIT2, showed high levels of activity against rice leaf folder in vitro and in planta. Oral ingestion of LMX protein led to a signif...

This paper discusses the influence of family supportive supervisor behavior (FSSB) on Work-family enrichment (WFE) of female university teachers and the mediating role of Leader-member exchange (LMX) through analyzing 183 valid questionnaires. The result shows that emotional support, role modeling and creative workfamily management have significant positive effect on female university teachers’...

Leader-member exchange (LMX) generally refers to the leadership process centered on the interactions between leaders and direct reports. The basic premise of high quality leader-member exchange relationships holds that direct reports gain tremendous benefits through these partnerships. LMX is perhaps the most commonly researched theory of leadership. However, few studies have specifically exami...

While the link between servant leadership and organizational citizenship behavior (OCB) has been established, the individual-level mechanisms underlying this relationship and its boundary conditions remain poorly understood. In this study, we investigate the salience of the mediating mechanisms of leader-member exchange (LMX) and psychological empowerment in explaining the process by which serv...

We examine the relationship between leader–member exchange (LMX) quality and advice network centrality using multisource data from a sample of 250 retail employees and their respective managers in Turkey to test our hypothesized model of value and costs of being sought out for advice. Drawing upon the tenets of network generation theory (Nebus, 2006), we predict that the tendency of focal actor...

The focus of this research is on the relationships between leader-member exchange (LMX), supportive supervisor communication (SSC), and subordinate job performance. It was predicted that the relationship between subordinate ratings of LMX quality and supervisor ratings of subordinate performance would be mediated by subordinate ratings of SSC. Specifically, it was hypothesized that LMX would di...
