Success of organizational initiatives for environmental sustainability hinges upon employees' proenvironmental behaviors. One of the contemporary important challenges faced by HR professionals is to ensure proper integration of environmental sustainability into human resource policies. The green human resource management (green HRM) has emerged from organizations engaging in practices related to protection of environment and maintaining ecological balance. The aim of this study is to examine the effects of green HRM practices (green recruitment and selection, green training and development, green performance management and appraisal, green reward and compensation, and green empowerment) on employee's proenvironmental behavior. Moreover, this study is going to test the mediating effect of proenvironmental psychological capital and the moderating effect of environmental knowledge on green HRM practices-proenvironmental behavior. Data from 347 employees working in coal generating, power industry, food, chemical, and pharmaceutical industries were collected. Results revealed that green HRM practices positively affected employee's proenvironmental behavior, and proenvironmental psychological capital mediated this link. Employee's environmental knowledge moderated the effect of green HRM practices on proenvironmental behavior.

Moral courage is a competency exercised in the workplace as employees face ethical challenges with a moral response. Managers exert considerable effort to foster subordinates' moral courage given its positive organisational consequences. However abusive supervision, not uncommon in the organisational context, negatively affects moral courage. The purpose of this article is to examine the relationship between abusive supervision and moral courage as well as to test the moderating roles of moral efficacy and moral attentiveness on that very relationship. Data were collected from six public hospitals in Pakistan. The sample included 359 nurses and 121 nurse heads. The moderating roles were tested using the moderated hierarchical regression analysis. Results revealed that there was a significant negative relationship between abusive supervision and moral courage. In addition, this very relation was weaker when both moral efficacy and moral attentiveness were higher than when they were lower. The study provided new insights into the influence that abusive supervision might have on nurses' moral courage and it also offered a practical assistance to employees in the health care industry and their leaders that moral efficacy and moral attentiveness would act as neutralisers in mitigating the pernicious effect of abusive supervision on nurses' moral courage.

Angiotensin converting enzyme (ACE) is a key component of renin angiotensin aldosterone system. It converts angiotensin I to angiotensin II. Insertion/deletion (I/D) polymorphism of ACE gene is found associated with several complications. However, its association with hypertension and related metabolic diseases is still controversial. So, the aim of the present study was to check this association for Punjabi population from Faisalabad, Pakistan. For this purpose, blood samples (patients = 100, controls = 48) were collected and several biochemical parameters were measured. Genotyping for ACE (I/D) polymorphism was performed by polymerase chain reaction (PCR) assay. ID genotype is found prevalent in the studied population as 41% in control subjects and 61% in patients. Furthermore, chi-square analysis showed significant (p = 0.005) difference for genotypic frequencies between both groups. One-way ANOVA for association of II, ID, and DD genotypes with anthropometric, clinical, and biochemical parameters showed that in patient group, DD genotype is significantly (p = 0.041) associated with systolic blood pressure (SBP). Moreover, ID genotype is found associated with the presence of cardiovascular diseases. This study concludes that DD genotype is strongly associated with higher SBP in hypertensive patients.
