NEXUSES OF ETHICAL LEADERSHIP, JOB SATISFACTION AND JOB PERFORMANCE IN ACADEMIA OF KHYBER PAKHTUNKHWA PAKISTAN

Nowadays universities are going through the transition due which new performance standards have been created. In such situation, performance of employees can be enhanced through effective ethical leadership. The current study has examined the dynamic links between job satisfaction, job performance and ethical leadership in the academia of Pakistan. Using a cross sectional design, quantitative data were collected from 150 academic staff working in three universities. Data were analyzed both by descriptive and inferential statistics. The results showed that four characteristics, i.e., practicing preacher; safe haven creator; moral motivator and ethical justice were positively associated with job performance, whereas this link was partially mediated by job satisfaction. The results obtained were in a strong concurrence with the existing literature. Hence, universities of Pakistan should focus on developing ethical leadership among their employees. In this way, universities can grow and contribute towards the socioeconomic development of Pakistan.

Factors of Correlation for Dynamic Links of Rotor Systems of Wind Electric Installation

The substantiation of definition of correlation factors for dynamic links of rotor systems of wind electric installations, as one of subtasks of the mathematical algorithms of dynamic behavior of system claimed for the further working out for the purpose of automated control updating fot the wind-electric installation which provides reduction of vibrations of all elements of rotor systems in conditions of loading a drive at different modes of operation of the energy-unit that promotes improvement of indicators of reliability for components of the modern wind installations is made. The problem of determining the parameters of the analytical model of the correlation function for the purpose of definition of correlation dependences between the measured values of meteorological and electro-power process taking into account the requirement of a minimum of the sum of squares of discrepancies (approximation errors) for the actual and approximating lines is solved. The average square deviation of an error of approximation, meteorological and electro-power process on the basis of a discrete estimation of ordinates of the analytical model of the correlation function does not exceed 1%. Mathematical formulas for definition of the spectral density of input and target casual processes, and also mutual spectral density of input and target casual processes of dynamic links of rotor systems on the basis of the block diagram of transfer functions of the system behavior for the purpose of revealing the degree of correlation of transfer functions are made. The analysis is made for processes of input and target signals of transfer functions with regard to their coherent state on the basis of calculation of factors of correlation for dynamic links of rotor systems for the purpose of the description of the transfer function within the limits of the analysis of vibrating fields of the unit as a whole since vibrations are causednot only by blades but also by all elements with rotor systems.

Evolution of Inequalities in Returns to Education: A Study Based on Tunisian Data

These paper aims are to study and estimate the evolution of the inequalities to the return on educational and professional investment, thus offering vast opportunities for analysis, in particular the dynamic links "profitability" - "investment". The general view is titled in the research field of human capital theory by analyzing three surveys provided by the National Statistical Institute that focus on wage-employment. We initially use a corrected Mincer model where we specify two types of regression then we will integrate the indicator of depreciation of human capital. Thus giving results that are used to understand the dynamics of individual investment choices. The results show a decrease in profitability and an increase in catch-up time (Overtaking). The study also makes it possible to understand the evolution of returns on educational and professional investments. To look for points of failure and imbalances in the education system and its relation to the labor market and to serve as a guide to government policy as it relates to long-term educational programs.
