ôbjective: m any theorists have attempted to illustrate family functions. the aim of this study was to examine the relationship between self-differentiation, mental well-being and welfare and the quality of an individual’s married life, specifically in the framework of bowen's theory. methods: the sample size for this descriptive research project consisted of 560 participants who were chos...

today water supply issue in large cities seems to be a big problem. this becomes more important with population growth and urbanization extension. to cope with this problem lots of irrigation and drainage projects have been implemented and operated that subsequently many socio- economic and cultural effects have been brought to the areas . the objective of the present study is to survey the soc...

although the research on organizational citizenship behaviors (ocbs) has increased dramatically in diverse fields during the past decade, little is known about the ocbs in the information systems area. the purpose of this study was to explore the effect of ocbs on information systems success. in order to perform empirical analyses, measurements on the ocbs constructs based on the five dimension...

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...

Asymptotic expansions are made for the distributions of the Maximum Empirical Likelihood (MEL) estimator and the Estimating Equation (EE) estimator (or the Generalized Method of Moments (GMM) in econometrics) for the coefficients of a single structural equation in a system of linear simultaneous equations, which corresponds to a reduced rank regression model. The expansions in terms of the samp...

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...
