This study examines the relationship between psychological contract breach, high-performance work systems, and employee engagement in public sector banks of Larkana, Pakistan. The study proposes that ...high-performance work systems can moderate the negative impact of psychological contract breach on employee engagement. The study draws upon social exchange theory and self-determination theory to frame the research questions and employs a quantitative methodology to test the hypotheses. The sample consists of 250 employees from public sector banks in Larkana, Pakistan has been taken to analyze the data. To examine the relationship between the latent variables, SPSS and smart PLS modeling have been used. The study finds that psychological contract breach has a significant negative impact on both employee engagement and high-performance work systems, while high-performance work system has a significant positive relationship with employee engagement. Overall, the study concludes that HPWS can lessen the negative effect of psychological contract breach and create a productive workplace that enhances employee engagement. The results support the hypotheses and have theoretical, practical, and methodological implications for HRM practices in public sector banks. The study recommends that organizations prioritize maintaining psychological contracts with employees and implementing HPWS to enhance engagement. Future studies should focus on addressing the study's limitations, such as its cross-sectional design and dependence on self-report measures.
Databases play an important role in cyber world. It provides authenticity across the globe to the legitimate user. Biometrics is another important tool which recognizes humans using their physical ...statistics. Biometrics system requires speedy recognition that provides instant and accurate results. Biometric industry is looking for a new algorithm that interacts with biometric system reduces its recognition time while searching its record in large database. We propose a method which provides an appropriate solution for the aforementioned problem. Iris images database could be smart if iris image histogram ratio is used as its primary key. So, we have developed an algorithm that converts image histogram into eight byte code which will be used as primary key of a large database. Second part of this study explains how color iris image recognition can take place. For this a new and efficient algorithm is developed that segments the iris image and performs recognition in much less time. Our research proposes a fast and efficient algorithm that recognizes color irises from large database. We have already implemented this algorithm in Matlab. It provides real-time, high confidence recognition of a person's identity using mathematical analysis of the random patterns that are visible within the iris of an eye.
Slope Stability Analysis is one of the main aspects of Open-pit mine planning because the calculations regarding the stability of slopes are necessary to assess the stability of the open pit slopes ...together with the financial feasibility of the mining operations. This study was conducted to analyse the effect of groundwater on the shear strength properties of soft rock formations and determine the optimum overall slope angle for an open pit coal mine at Thar Coalfield, Pakistan. Computer modelling and analysis of the slope models were performed using Slide(v. 5.0) and Phase2 (v. 6.0) software. Integrated use of Limit Equilibrium based Probabilistic (LE-P) analysis and Finite Element Method (FEM) based shear strength reduction analysis was performed to determine the safe overall slope angle against circular failure. Several pit slope models were developed at different overall slope angles and pore-water pressure ratio (Ru) coefficients. Each model was initially analysed under dry conditions and then by incorporating the effect of pore-water pressure coefficients of Ru = 0.1, 0.2, and 0.3 (partially saturated); finally, the strata were considered to be fully saturated. It was concluded that at an overall slope angle of 29 degrees, the overall slope will remain stable under dry and saturated conditions for a critical safety factor of 1.3.
