High-quality leader-member exchange (LMX) is commonly seen as beneficial to employees. However, this is not always the case in the eyes of other members of the same team. Based on social comparison theory, we propose that members who have high-quality LMX relationships with team leaders might face workplace ostracism through being envied by other members of the same team. Further, we hypothesiz...

Leader-member exchange (LMX) represents the quality of interaction between leaders and members of a work unit, such as the information system function within an organization. LMX is expected to improve organizational citizenship behavior, beneficial behaviors not explicitly rewarded, but prior research has failed to establish this link satisfactorily. To determine the influence of LMX in the IS...

This study compared the performance of LMX(R) broth (LMX), Chromocult Coliform(R) agar (CC) and Chromocult Coliform agar plus cefsulodin (10 microg ml-1) (CC-CFS), with standard methods multiple tube fermentation (MTF), for the enumeration of total coliforms and Escherichia coli from marine recreational waters. LMX and CC are two media designed to concurrently detect total coliform (TC) bacteri...

Leader-Member Exchange (LMX) theory suggests that the quality of the leader-employee relationship is linked to employee psychological health. Leaders who reside at different hierarchical levels have unique roles and spheres of influence and potentially affect employees' work experiences in different ways. Nevertheless, research on the impact of leadership on employee psychological health has la...

In a field study of 128 middle-managers in similar roles but in different organizations within the UK public sector, we find that the quality of their leadermember exchange (LMX) relationship with their immediate supervisor is negatively related to the three dimensions of burnout. As hypothesized, LMX and communication frequency are found to interact in the prediction of emotional exhaustion. F...

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...
