Organizational justice and organizational citizenship behavior: the mediating role of work engagement

The intention of this paper is to investigate the mediating role of work engagement between the four dimensions of organizational justice (OJ) and organizational citizenship behavior (OCB) dimensions. The current literature appears to have overlooked the mediating role of work engagement (WE) in the link between justice and organizational citizenship behavior (OCB) in higher education institutions (HEIs). As a result, it appears to be one of the primary studies of its kind to investigate the relationship between OJ dimensions (e.g., procedural, distributive, informational, and interpersonal justice) and OCB dimensions (e.g., OCBI and OCBO). Data were collected from 121 faculty members from ten private universities operating in Bangladesh. The PLS-SEM was employed to investigate hypotheses. The investigation found OJ is positively connected to WE. Besides, WE is significantly related to OCB. Moreover, WE mediated the relationship between OJ dimensions and OCB dimensions, except for the relationship between PJ and OCB dimensions. The study provides necessary guidelines for the organizations regarding how they might improve citizenship behavior by ensuring justice and engagement in the workplace. Therefore, the application of the findings might ensure better employee outcomes and organizational productivity.

[Association of health-related physical fitness with kidney function and lipid profile among faculty in a university]

Objective: To study the association of health-related physical fitness (HPF) with kidney function and blood lipid to provide a basis to prevent chronic diseases and making exercise prescriptions. Methods: This study was conducted in December 2019 with 299 faculty members of a university in Shaanxi, testing HPF indicators (muscle mass, body fat percentage, grip, sit-and-reach, vital capacity) , kidney function indicators (creatinine, uric acid, urea) , and blood lipid indicators[triglyceride (TG) , total cholesterol (TC) , high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) ]. Spearman correlation analysis and binary logistic regression were used to analyze the association between HPF with kidney function and blood lipid indicators. Results: In men, muscle mass and grip strength were positively correlated with uric acid, body fat percentage was positively correlated with TG, sit-and-reach and vital capacity were negatively correlated with TG (r(s)=0.266, 0.337, 0.300, -0.339, -0.239, P<0.05) . In women, body fat percentage was positively correlated with uric acid, TG, TC and LDL-C, negatively correlated with creatinine and HDL-C, grip strength was positively correlated with creatinine, sit-and-reach was positively correlated with HDL-C and negatively correlated with TG, vital capacity was negatively correlated with urea (r(s)=0.240, 0.349, 0.214, 0.249, -0.254, -0.209, 0.186, 0.207, -0.255, -0.154, P<0.05) . Logistic regression showed that high body fat percentage was risk factor for abnormal uric acid and dyslipidemia in female faculty members (OR=1.114, 95%CI:1.023-1.213; OR=1.116, 95%CI: 1.034-1.208; P<0.05) . And high body fat percentage was risk factor for dyslipidemia in male faculty members (OR=1.129, 95%CI: 1.017-1.252, P<0.05) . Conclusion: High body fat percentage is associated with dyslipidemia and uric acid abnormalities in university faculty. HPF fitness assessment may be important for the prevention of chronic diseases related to kidney function or lipids.

Burnout in university faculty: An interaction between subjective sleep quality and the OXTR rs2268498 polymorphism

BACKGROUND

Job burnout is a stress-related syndrome influenced by both genetic and environmental factors. Poor sleep quality acting as a stressor may lead to job burnout. The oxytocin receptor gene (OXTR) related to stress reactivity may also exert an effect on job burnout. We aimed to explore the effect of sleep quality, a functional OXTR rs2268498 polymorphism, and their interaction on job burnout in the Chinese population, which has not been explored yet.

METHODS

A preliminary study was performed using a cross-sectional design. The Pittsburgh Sleep Quality Index (PSQI) and the Malash Burnout Inventory (MBI) were measured from 575 healthy subjects. The OXTR rs2468498 polymorphism was genotyped in 376 subjects.

RESULTS

There were significant main effects of sleep quality (p<0.05), but not of the OXTR rs2468498 genotype on burnout. Interestingly, the interaction between sleep quality and the rs2468498 genotype was significant (p<0.05). In the poor sleep group, the C allele (C/C and T/C) carriers showed higher Emotional Exhaustion level than T homozygotes, while in the good sleep group, the C allele carrier showed a lower Emotional Exhaustion level.

LIMITATIONS

This study covered subjects from only one university and the sample size for genotyping was relatively small. As we analyzed only the OXTR rs2268498 polymorphism, this study could not reveal the effects of the cerebrospinal oxytocin concentration and the haplotypes.

CONCLUSIONS

Our findings suggest that the OXTR polymorphism modulates the influence of subjective sleep quality on burnout. We conclude that the C allele of the OXTR rs2468498 polymorphism plays a susceptible role in job burnout.
