Employee Commitment and Culture Organization on Employee Performance

This study aims to analyze and examine the influence of employee commitment and cultural organizational factors towards employees of the Job Performance, Regional Secretariat (SetDa) Riau Province both simultaneously (overall test) and partial (individual test). The research method used is verification, while the population in this study is the Regional Secretariat (SetDa) Riau Province based on increasing totaling 402 people. By using the method of proportional stratified random sampling in the sample amount to obtain 40 respondents. While data collection technology is used by the field study and library that includes observation, interviews and question-naires, and to determine the relationship and the influence of an independent variable to the model variables to use Multiple Linear Regression Analysis. The results showed that the calculated results obtained statistically Multiple Correlation Coefficient (R) was 0.8950 with p <0.05 and the coefficient value of Determination (R2) 80.11%. This means that approximately 80.11% of employee commitment and organizational culture factors have a significant influence on employee job performance. Partial test showed that the partial coefficient of determination values contained in the organizational culture variables for (r2) = 54.58% with p = 0.00000 and tresult = 7.515> ttable = 1.678 and ttable variables for employee commitment (r2) = 78, 74% with p = 0.00000 and tresult = 13.196> ttable = 1.678. These results indicate that organizational cultural factors and employee commitment have a significant relationship influence on employee job performance of the Riau Province Regional Secretariat (SetDa).

A Study of Nonlinear Partial Differential Equations for Exact Solutions

This study is dedicated to the subject of constructing exact solutions of nonlinear partial differential equations arising in engineering science, mathematical physics, fluid mechanics, quantum mechanics etc. The significance of nonlinear partial differential equations lies in the fact that the mathematical modeling of many real life phenomena involves differential equations. Several new nonlinear evolution equations are reported to appear in recent scientific studies. The investigation of exact solutions of nonlinear partial differential equations is of great value in understanding widely different physical phenomena. In late years, many fractional order evolution equations are applied successfully to model various physical phenomena. The memory effects of the fractional derivatives play an important role in understanding mechanical and electrical attributes of actual materials. The aim of this dissertation is to extract the exact solutions of some important nonlinear partial differential equations of integer order as well as non-integer order, for instance the nonlinear short-pulse equation, nonlinear fractional biological population model, the nonlinear complex Ginzburg-Landau equation, the generalized fractional Zakharov-Kuznetsov equation, time-fractional Chan-Allen equation, the fractional dispersive modified Benjamin-Bona-Mahony equation and (2 + 1)−dimensional solution equation. Some well known integration techniques are implemented in carrying out the travelling wave solutions of these equations. The obtained solutions may be worthwhile for explanation of some physical phenomena accurately.
