in today’s complex, dynamic and ever changing modern environment, all companies need to design and use strategies helping them to improve continuous performance, because in such a competitive environment, those companies which keep pace with changing and dynamic conditions of competitive market are able to survive. this study was conducted using descriptive – correlational methodology. the stud...

in this study, which is in the course of help to the development of the export and the export marketing in the realm of the food industries, ten factors including the firms size, the export experience, the export stimuli, the export problems, the competitive advantages, the export commitment, the adaptation product strategy, the adaptation pricing strategy, direct export channel and overseas ad...

The correlation analysis of the independence between the behavioral influencing factors has been performed in order to find the non-independent factors. Among the Human Factors Analysis and Classification System (HFACS), the impact of the high-level factors on the bottom level is determined. This study uses empirical method, namely Structural Equation Modeling (SEM) to build the relationship mo...

Purpose: Considering the importance of human resources and increase leaving job positions, the aim of this study was structural equations modeling of effective dimensions of job alienation. Methodology: The present study was a cross-sectional from type of correlation. The research population was the employees of the government organizations of Isfahan city in 2021 year, which number of 400 peo...

A time-accurate procedure to model fluid/structure interactions of helicopter blades is presented. The Navier-Stokes equations in conjunction with the one-equation SpalartAllmaras turbulence model are used to compute the flow. Structural dynamics is modeled using the modal equations. The aerodynamic and structural dynamic equations are coupled time-accurately using the linear acceleration metho...

Ecological systems are commonly studied by very concrete conventional models or very abstract random matrix models. Here we review and extend the approach of generalized structural kinetic modeling, that offers an intermediate way between these extremes. Generalized models describe systems with a specific structure, but do not restrict the processes in the model to specific functional forms. Th...

Critiques of the concept of key success factors have raised objections both conceptually and methodologically. From the latter perspective, common research practice is criticized for neglecting the influence of firm-specific, unobservable variables (e.g., management skills). To control for these effects a structural equation approach (“LISREL”) to the analysis of panel data is proposed. In an e...

Theil, Basmann, and Sargan are often credited with the development of the two-stage least squares (TSLS) estimator of the coefficients of one structural equation in a simultaneous equations model. However, Anderson and Rubin had earlier derived the asymptotic distribution of the limited information maximum likelihood (LIML) estimator by finding the asymptotic distribution of what is essentially...
