Abstract Organic mixed livestock farming offers a range of potential benefits for the environment. Due to diversification enterprises, this system can be associated with high workload, which means that it could socially unsustainable. The aim study was understand and explain work satisfaction farmers running an organic farm. Using mixed-method approach, quantitative qualitative data were collec...

Risk is an inherent factor in the traveler's choice of destination. Tourism destinations differ in many aspects including their location, economic condition, cultural and political status and crime. Given such differences, the analysis of destination risk and its dimensions is of substantial interest. The current study explores the risk factors perceived about Iran as a tourism destination usin...

this paper deals with scrutinizing the convergence properties of iterative methods to solve linear system of equations. recently, several types of the preconditioners have been applied for ameliorating the rate of convergence of the accelerated overrelaxation (aor) method. in this paper, we study the applicability of a general class of the preconditioned iterative methods under certain conditio...

this research work is devoted to the development of a mathematical model for the simulation of the flow of polymeric melts through the die region of extruders. a set of governing equations are solved using finite element method. standard galerkin technique is used in conjunction with the mixed scheme to solve the flow equation. due to the non-linear nature of global equations, the picard iterat...

in this paper, we propose a new numerical method for solution of urysohn two dimensional mixed volterra-fredholm integral equations of the second kind on a non-rectangular domain. the method approximates the solution by the discrete collocation method based on inverse multiquadric radialbasis functions (rbfs) constructed on a set of disordered data. the method is a meshless method, because it i...

the set covering problem (scp) is a well-known combinatorial optimization problem. this paper investigates development of a local branching approach for the scp. this solution strategy is exact in nature, though it is designed to improve the heuristic behavior of the mixed integer programming solver. the algorithm parameters are tuned by design of experiments approach. the proposed method is te...

Patient education is a central component in high-quality integrated care of patients with chronic pain. The current study assessed patients' satisfaction with a 12 wk "Pain Education School" program within the initial 2 yr phase of implementation. A mixed-method treatment outcome design was used. A sample of 219 veterans between November 6, 2009, and January 20, 2012, was evaluated. Quantitativ...

With an increasing amount of arising crowdsourcing initiatives, insights are needed on how to successfully drive initial and sustained platform-activity, as a form of value cocreation between crowdsourcer and crowdsourcees. Therefore, the engagement concept, known as a micro-foundation of value co-creation, serves to holistically understand crowdsourcees’ psychological and behavioral responses ...

A truly meshless Galerkin method is formulated in the present study, as a special case of the general Meshless Local Petrov-Galerkin (MLPG) “Mixed” approach. The Galerkin method is implemented as a truly meshless method, for solving elasto-static problems. In the present Galerkin method, the test function is chosen to be the same as the trial function, as a special case of the MLPG approach. Ho...
