The well-known structural model used to estimate market structure suffers from a severe collinearity problem if the marginal cost and demand equations are linear.

in this study, attempts are made to recognize effective factors in enhancing the intension to use online stock trading application by real investors via combining the models of reasoned action and decomposed theory of planned behavior and merging it with dimensions of online stock trading. questionnaires designed and ditributed between 300 people attended in tehran stock exchange and agah broke...

concern for the environment is a constantly growing phenomenon. awareness of most peopleand governments in the world with regard to this question has risen. sometimes, this position is inverselyproportional to economic growth, leading to a situation where a more environmental stance on the part of end users has often not been supported by more restrictive environmental protection laws. this stu...

the purpose of this study is to survey ethical organization and its influence on social responsibility of organization in ministry of agriculture jehad. mediator factor in this research is organizational culture. five hypotheses were explored. 313 statistical samples were selected from the staff of ministry of agriculture jehad through multistage sampling. the method of research is descriptive ...

The principal goal of this research is developing physics-based, reduced-order, analytical models of nonlinear fluid-structure interactions associated with offshore structures. Our primary focus is to generalize the Hamilton's variational framework so that systems of flow-oscillator equations can be derived from first principles. This is an extension of earlier work that led to a single energy ...

This research combines Volterra theory and proper orthogonal decomposition (POD) into a hybrid methodology for reduced-order modeling of aeroelastic systems. The outcome of the method is a set of linear ordinary differential equations (ODEs) describing the modal amplitudes associated with both the structural modes and the POD basis functions for the fluid. For this research, the structural mode...

in today’s leading organizations, employees’ empowerment is considered as a significant issue in human resource management cycle and it has become a central theme of management functions and practices. the present study aimed to investigate the relationship between empowerment of staffs and organizational commitment with organizational health mediation. the results showed that there is a relati...

in recent decades, empowerment as delegation of power to someone has been used a mechanism to increase personal and work life quality of women. higher education and occupation are effective instruments for empowering women but the role of culture can't be denied in this relation. social norms can directly or indirectly limit women's empowerment. in this article the role of higher educ...

Interaction between a structure under base excitation and heavy non-structural elements that it supports is significant in the seismic analysis and design of the structure. Heavy non-structural elements may slide/rock under base excitation, and this dynamic action affects the seismic behavior of the supporting structure. Hence, in this study, a numerical model was presented to describe the seis...
