Occupational Stress among Secondary School Heads: A Gender Based Comparative Study

The purpose of the study was to examine and compare the occupational stress of male and female secondary-school-heads in Khyber Pakhtunkhwa. All the male and female secondary school heads working in pubic secondary schools of Khyber Pakhtunkhwa constituted the population of the study. A total of 402 secondary school heads were selected as sample through multistage sampling technique in which 260 were males and 142 were females. Descriptive and quantitative survey research design was used. To seek the responses from the participants, a standardized tool i.e., “Occupational Stress Index (OSI)” was used. For statistical analysis, proper descriptive statistics i.e., mean, standard deviation and inferential statistics i.e., independent samples t-test were employed through SPSS. The findings revealed that both male and female secondary school heads were found occupationally stressful with respect to role overload, role conflict, strenuous working condition, unreasonable group & political pressure, under participation, and unprofitability. Comparatively, there was no significant difference between the overall occupational stress of male and female secondary school heads. Based on findings, it was recommended that Elementary & Secondary Education Department should have a collaboration with policymakers to develop comprehensive strategies for stress reduction for secondary school heads so that they may perform their duties effectively.Keywords: comparative study, gender based study, occupational stress, secondary school head

Synthesis of Zeolites from Coal Fly Ash and Their Environmental Application

This study aims to make adsorption-capable zeolite from coal fly ash, a waste product from coal-fired power plants (CFA). When it comes to commercializing sorbent, the total cost and efficiency of the adsorbent material are critical. This work used tap water instead of distilled water (DW) to synthesis zeolite from fly ashes at 90°C crystallization temperatures. The discovery lays the door for a cost-effective but easy technique of synthesizing viable zeolitic materials for adsorption applications using waste products like coal fly ash. According to the comprehensive characterization, the support for the use of TP to make zeolites is based on its larger particle size, and lower carbon impurities. The generated zeolite was homogenous and A-type, and applied as an adsorbent to remove traces of heavy metals contaminants. During a 25-minute agitation period, the zeolites produced with TP had a greater adsorption capacity. In principle, the proposed approach permits the synthesis of low-cost, high-efficiency zeolite-based adsorbent materials for environmental remediation without the use of harmful or expensive chemicals

Socio-Economic Impact Assessment of Small Dams Based on T-Paired Sample Test Using SPSS Software

A dam is a barrier/structure that impounds water and retains it for later use. Thus, it plays an important role and offers a reserve stock of water for rural communities in remote areas. The present study was conducted to assess the socio-economic impact of small dams on local communities. The impact was analyzed based on descriptive statistics and t- paired sample tests using SPSS software to study and analyze the Nagarparkar area, Sindh, Pakistan. Primary and secondary data were used for collecting the data. The data was collected randomly from 250 people through interviews and group discussions Also, 104 sets of data were obtained through a questionnaire survey. The overall results summary of the parameters revealed that a significantly positive variation occurred in the study area after construction of the dam. The number of the packa houses and water depth were increased. The distance to collect water and water-fetching time were decreased 6% and 5.61 % respectively. The overall average area cultivated with crops was increased by 26.55%. The average yield of almost every crop in both Rabi and Kharif seasons were increased by 55% in the areas surrounding the dams. The overall number of livestock was increased by 18.08%, while the number of horses decreased by 1.5% after construction of the dam. The income, expenditure, and savings have increased significantly to 36.16%, 17.68%, and 32.15%, respectively, while the migration rate has decreased19.09% since construction of the dam. The choice of crops has also changed from inferior crops to superior and market-oriented crops. The water table and quality have improved, and wells have been recharged

Land Covers Change Assessment After Small Dam’s Construction Based on the Satellite Data

The small dams were constructed in the study area for storing the rainwater. The present study was conducted to assess the impact of small dams on the LCC (Land Cover Change) in Nangarparkar, Pakistan based on the satellite data. The ENVI (Environment for Visualizing Images) software was used for classification of the four year’s images and three classes viz. water, vegetation, and soil were taken for detection of LCC. The MLH (Maximum Likelihood) supervised method was used to classify the multispectral satellite images. The classified results of the classes were found different each year before and after dam construction. Average results of the two years before dam’s construction revealed that water availability, vegetation cover and soil cover was 3.02%, 18.52%, and 32.30% respectively. However, after the dam construction, the water availability, vegetation cover and soil cover was 8.49%, 34.33%, and 17.15% respectively. Overall results revealed that water availability and vegetation cover were increased by 5.47 % and 15.18% respectively while soil cover decreased 15.15% after the construction of dams. Hence, based on the results, it is confirmed that the constructions of small dams have a direct and indirect positive impact on the land cover changes and it can play an important role in the resettlement of the communities of the arid areas
