Association between Perceived Organizational Politics and Work-Related Attitudes among Bankers: Moderating Role of Personality Traits
Get PDFOrganizational politics is evident across the globe within organizations. This emergent issue needs further investigation with reference to employee personality. The intention of the current study was to better understand how employees respond to organizational politics. The primary goal of the current research was to examine the moderating role of personality factors on bankers\u27 perceptions of organizational politics and attitudes toward their jobs (i.e. job satisfaction and organizational commitment). The data were gathered from 150 employees working in various banks in Multan, using self-reported questionnaires to find their organizational political perceptions, job satisfaction surveys, organizational commitment, and personality tests. Hierarchical regression analyses were used to analyze the model. The personality factor that moderated the link between perceived organisational politics and work-related attitudes was openness to experience. Extroversion and organizational politics had a negative correlation. The outcome of the study depicted a significant link between job satisfaction and organizational politics. The study’s findings add to our understanding of the significance of personality traits concerning how workers view organizational commitment, organizational politics, and their level of job satisfaction

Exploring Possibilities of Engaging Parents in an Early Childhood Classroom in City Naudero District Larkana
Get PDFParents’ engagement plays a vital role in getting information regarding children\u27s education and their progress. This role is not played by each parent but those who play it remain aware of their children\u27s progress and it also helps school administrations in contacting students’ parents easily and in sharing their concerns regarding children and school work. The present paper reports the findings of a researcher study that aims to analyse the current practices of parental engagement as well opportunities and challenges provided and faced by teachers and parents. For detail analysis, a qualitative approach was used with the help of semi-structured interviews which were taken from teachers and the parents. Three parents and three teachers were selected as participants with the help of a purposive sampling technique. Detailed interviews were taken with the participants to get detailed data regarding parental engagement in the research context. Most of the school staff and the parents were very much positive regarding the role of parental engagement in the school but the engagement level was very low. The findings of the study recommend arranging teacher-parent meetings or arranging such activities where parents could be involved in the learning process of their children
Work-Family Conflict, and Job Satisfaction: Moderating Role of Family Support
Get PDFThis study aimed to investigate the relationship between Work-Family Conflict and Job Satisfaction among school teachers by exploring the moderating influence of family support. The research employed several instruments, including a Demographic sheet, the Job Satisfaction Scale, a multidimensional scale of perceived social support, and a work-family conflict scale. This study employed a correlational research design to fulfill its objectives, with data collection conducted through convenient purposive sampling methods from school teachers. The findings revealed a negative association between Work-Family Conflict and Job Satisfaction, indicating that higher conflict levels were linked to decreased job satisfaction among teachers. Additionally, Family support demonstrated a positive correlation with Job Satisfaction, underscoring its importance in enhancing teachers\u27 job satisfaction. Moreover, family support was identified as a moderator in the relationship between Work-Family Conflict and Job Satisfaction, indicating its role in alleviating the negative impact of work-family conflict on job satisfaction. In order to improve teachers\u27 job satisfaction and general well-being, educational institutions should think about putting strategies in place to support a healthy work-family balance for their faculty members. These findings should be considered by policymakers as they develop measures to uphold the teaching profession and guarantee educators\u27 job satisfaction
Optimization and Characterization of Flavipin Produced by Aspergillus Terreus
Get PDFThe secondary metabolites of microorganisms serve as defence or signalling molecules in ecological interactions, revealing substantial survival benefits in nature. As a result, many researchers have concentrated on screening and optimizing the production of these molecules from natural sources such as microorganisms with the objective of pharmacological uses, primarily as antibiotics or anticancer agents. In this study, 80 isolates of Aspergillus were investigated for the production of flavipin. These fungi were collected from various locations and laboratories. Flavipin was estimated by using a standard curve, then purified by using silica gel chromatography, followed by identification using thin layer chromatography (TLC), and High Performance liquid chromatography (HPLC). The fermentation conditions were carried out at the Central Health Laboratory/Maysan Health Directorate from April 2021 to August 2022. Out of eighty isolates of Aspergillus, only one isolate was identified as producer of flavipin which was Aspergillus terreus. According to HPLC analysis, the retention times of flavipin and its standard were 7.7 minutes and 7.6 minutes, respectively. By using the TLC technique, the relative flow (Rf) value was 0.55 cm for both standard flavipin and flavipin. The optimization of growth conditions and production of flavipin were studied. It is revealed that optimum conditions were as follows: pH 7 on 16 days, the temperature of 25oC for 12 days, culture volume of 50 ml on the 16th day, shaking speed of 150 rpm on the 12th day, inoculum size of 8 fungal agar disc on the 12th day, the optimal incubation period of 14 days, and Potato Dextrose Broth as the optimal culture media. The aim of the study was to determination of optimal conditions for the flavipin production that produced by Aspergillus terreus. For yielding a profuse amount of flavipin, the incubation and fermentation conditions such as temperature, the culture volume, shaking speed, inoculum size, pH of the medium, incubation period, and the type of culture media should be considered and the optimal one must be chosen

Electrochemical Behaviour Study of KF in Artificial Saliva Mediated by GCE Using Cyclic Voltammetry
Get PDFA new study used potassium fluoride (KF) in different concentrations (2% and 5%), one of the components in the complete denture as supported material. The study aims to find the electrochemical analysis by cyclic voltammetric (CV) technique of the physical properties of this material and the influence in artificial saliva (AS) by oxidation–reduction peak current in the oral cavity. This study used a glassy carbon electrode (GCE) as a working electrode, Ag/AgCL as a reference electrode, and platinum wire as an auxiliary electrode in the cyclic voltammetry cell. Different physical properties such as concentration, pH, scan rate, and reproducibility study were used in the potential-state. The results showed two oxidation peaks current at 1.4 and 0.75 Volt characterize to the artificial saliva and KF respectively, and one reduction peak current at -0.5 Volt for KF. All peaks were enhanced by increasing the concentrations and scan rates that indicate the study in the right response. Using different pH, the oxidation peak of KF disappeared in alkaline pH and enhanced in an acidic medium, so the KF ions act as an oxidative reagent in artificial saliva of acidic pH, and antioxidant in alkaline pH at a limited concentration of KF in the cavity of the mouth. The low concentration of KF (2%) used in the component of total denture is more favourable than the high concentration (5%). In addition, it is better to store the total denture in an alkaline solution after use to avoid any damage to the mouth cells
