RESUMO

In this technologically developed scenario, many organizations in developing countries including Pakistan have expanded the enthusiasm for understanding and creating an encouraging administrative and managerial environment. Numerous organizations are struggling for structural changes by deserting the old-fashioned organizational management style and implementing an empowering leadership where leaders give more authority to subordinates in decision making and responsibilities with the aim to increase organizational productivity. Therefore, the study examined the leadership empowering behaviour as a predictor of employees' psychological well-being of the educational institutions at secondary level in Kohat Division, Pakistan. A total sample of 564 secondary school teachers (male n = 379; female n = 185) was carefully chosen through a stratified random sampling technique. In this study, a non-experimental predictive correlational design was adopted. In order to collect data from the participants, two different standardized research tools i.e., the Leader Empowering Behaviour Questionnaire and Ryff's Psychological Well-being Scale were used. After the collection of data, it was analyzed on the basis of mean, standard deviation, Pearson's product-moment correlation, and multiple linear regression model. In conclusion, the study confirmed a significant positive correlation between leadership empowering behaviour and employees' psychological well-being. Leadership empowering behaviours predict employees' psychological well-being positively. Therefore, it was recommended that empowering behaviour might be adopted by the school leaders to improve the employees' psychological well-being for better organizational productivity.

RESUMO

BACKGROUND: Jalili syndrome (JS) is a rare cone-rod dystrophy (CRD) associated with amelogenesis imperfecta (AI). The first clinical presentation of JS patients was published in 1988 by Jalili and Smith. Pathogenic mutations in the Cyclin and CBS Domain Divalent Metal Cation Transport Mediator 4 (CNNM4) magnesium transporter protein have been reported as the leading cause of this anomaly. METHODS: In the present study, a clinical and genetic investigation was performed in a consanguineous family of Pakistani origin, showing characteristic features of JS. Sanger sequencing was successfully used to identify the causative variant in CNNM4. Molecular dynamics (MD) simulations were performed to study the effect of amino acid change over CNNM4 protein. RESULTS: Sequence analysis of CNNM4 revealed a novel missense variant (c.1220G>T, p.Arg407Leu) in exon-1 encoding cystathionine-ß-synthase (CBS) domain. To comprehend the mutational consequences in the structure, the mutant p.Arg407Leu was modeled together with a previously reported variant (c.1484C>T, p.Thr495Ile) in the same domain. Additionally, docking analysis deciphered the binding mode of the adenosine triphosphate (ATP) cofactor. Furthermore, 60ns MD simulations were carried out on wild type (p.Arg407/p.Thr495) and mutants (p.Arg407Leu/p.Thr495Ile) to understand the structural and energetic changes in protein structure and its dynamic behavior. An evident conformational shift of ATP in the binding site was observed in simulated mutants disrupting the native ATP-binding mode. CONCLUSION: The novel identified variant in CNNM4 is the first report from the Pakistani population. Overall, the study is valuable and may give a novel insight into metal transport in visual function and biomineralization.

RESUMO

The purpose of the study was to examine the relationship between perceived occupational stress and psychological well-being among secondary school heads in Khyber Pakhtunkhwa. A sample of 402 secondary school heads (male n = 260, female n = 142) was selected through multistage sampling technique. A descriptive, quantitative and correlative research design was used. For gathering information from the participants, two standardized tools i.e., "Occupational Stress Index (OSI)" and "Ryff's Psychological Wellbeing Scale (RPWB)" were used for measuring perceived occupational stress and psychological well-being respectively. For statistical analysis, mean, standard deviation, Pearson's product-moment correlation and multiple regression were employed. The findings revealed that there is a strong negative correlation between perceived occupational stress and psychological well-being. Furthermore, moderate negative correlation was found between all the sub-scales of perceived occupational stress and psychological well-being. All the subscales of occupational stress except low status were found significant predictors and have negative effect on psychological well-being of secondary school heads. So, it was suggested that Elementary & Secondary Education Department Khyber Pakhtunkhwa should have a collaboration with policy makers to formulate a comprehensive strategy for stress reduction management for secondary school heads so that they may develop good psychological well-being and perform their duties effectively.
