This study investigated the structural model of the effect of perception and attitude on social responsibility, organizational identity, and organizational citizenship behavior in sports and youth departments. The methodology was a descriptive survey that was conducted in the field. The statistical population was all employees of sports and youth departments of Khorasan Razavi province (180 people). The sampling method was counting. The research tool was Barrantes's‎ (2012) research questionnaire. Twelve professors of sports management confirmed the face and content validity of the questionnaire. Cronbach's alpha coefficient of the whole questionnaire was 0.83, which indicates the appropriate reliability of the measurement tool. A structural equation modeling approach with PLS 2 software was used to analyze the data. Based on the results, the perception of social responsibilities has a positive and significant effect on social responsibility, organizational identity, and organizational citizenship behavior. Also, the attitude towards social responsibilities positively affects organizational identity, which has a positive and significant effect on employee citizenship behavior. According to the results, performing social responsibility and creating a positive perception and attitude towards it in employees can effectively strengthen the organizational identity of employees and their organizational citizenship behavior.

Applying and combining h and p refinement techniques in isogeometric method with the possibility of continuity elevation that this method provides, convergence and error of using different kinds of shape functions with different orders and continuities is investigated. It is done in a numerical analysis framework of a practical and well known problem called “Diametral Compression Test”. The advantage of this case is its circular geometry, since IGA provides designers with high potency of the possibility of using minimum elements to make the exact circular geometry. The point load inserts singularity to the problem. The refinement is utilized uniformly as the effective parameters are limited to the kind, order and continuity of shape functions. With different refinement techniques the convergence of approximated solution to the exact solution of linear elasticity is examined. It is concluded that with the singularity that mentioned, the error in IGA is not necessarily reduced with raise in order, more precisely the level of continuity is another important issue to determine error raise. It is also seen that in the presence of point load singularity the rate of error converges to the same value for all degrees of NURBS and lagrangian shape functions with any continuity. At the beginning of refinement process the minimum number of elements is used to make the process clearer to understand. In next steps h and p techniques and their combination is used to refine the model.
