abstract this paper proposes an approach to find an optimum structure for educational levels of human forces. to this end, a linear programming (lp) model integrated with a social accounting matrix (sam) was employed. the integrated model was employed using the sam of golestan province of iran. it was demonstrated that when unemployment is the result of inconsistency between supply and demand f...

introduction: the aim of this study was to evaluate the effect of proximal contour of class ii composite restorations placed with straight or contoured matrix band using composite resins with different modulus of elasticity on stress distribution by finite element method. methods: in order to evaluate the stress distribution of class ii composite restorations using finite element method, upper ...

in this paper, exact solution for two-plane transverse vibration analysis of axial-loaded multi-step timoshenko rotor carrying concentrated masses is presented. each attached element is considered to have both translational and rotational inertia. forward and backward frequencies and corresponding modes are obtained using transfer matrix method (tmm). the effect of the angular velocity of spin,...

An intensive analysis of the dependence structure among stock markets is invaluable to financial experts, policy makers, and academic researchers, providing them with important implications for portfolio management, policy-making, and risk assessment. This paper proposes a novel spatiotemporal model to both examine global stock market linkages and investigate what drives stock returns. The newl...

food security has a dynamic notion during the time and may be affected by various domestic and global factors.nevertheless, iranian policy makers consider food security as same as self-sufficiency in agricultural food products, particularly wheat production. however, self-sufficiency can contribute to food security only if it is in coincidences with comparative advantage and sustainable resourc...

Introduction The importance of evidence-informed health policy making is widely recognised and frameworks exist to help understand the roles of different types of evidence [1,2]. However, there is limited application of these frameworks in empirical studies, particularly to inform learning and improve evidence-informed health policy development in LMICs. The objective of this presentation is to...

At the core of modern macroeconomics is some version or another of the famous Phillips curve relationship between inflation and unemployment. The Phillips curve, both in itspriginal and more recently reformulated expectations-augmented versions, has two main uses. In theoretical models of inflation, it provides the so-called “missing equation” that explains how changes in nominal income divide ...

Matrix-variate beta distributions are applied in different fields of hypothesis testing, multivariate correlation analysis, zero regression, canonical correlation analysis and etc. A methodology is proposed to generate matrix-variate beta generator distributions by combining the matrix-variate beta kernel with an unknown function of the trace operator. Several statistical characteristics, exten...
