increasing non-oil exporting is among the most important concerns for iran. software industry is among the knowledge based and profitable ones. identification of factors affecting export performance of software developers can improve planning that in turn results in increasing software export. in this research a model consisting of seven important variables in software industries including: com...

the aim of this study was to investigate the effect of positive normative feedback on acquisition and retention of throwing skill. the method was quasi-experimental and the population consisted of the 5th grade elementary female students. 60 students were randomly selected from the population and were randomly assigned to four different groups: normative task-orientation, non-normative task-ori...

the study of entrepreneurial orientation concept and codifying a proper strategy to improve the performance of companies has a great importance as the companies have allocated more product market share to themselves by representing new and unique products according to customers’ requirements. the purpose of this study is to examine the impact of entrepreneurial orientation and competitive strat...

the aim of this study was to model the effect of athletic identity on sport orientation in athletes participating in 11th sport olympiad of male students in iran. 400 students were selected as the sample of this study from 2130 students of population. sport orientation questionnaire (soq, gill et al., 1988, α=0.87) and the athletic identity questionnaire (cieslak, 2004, α=0.82) were used. the s...

the aim of this study was to determine the validity and reliability of moral orientation questionnaire in the student athletes. the statistical population consisted of physical education students of mashhad ferdowsi university (n=450). 186 subjects were selected randomly as the sample. 14-item moral orientation questionnaire (miltiadis, 2010) was used which included 2 factors (deontological eth...

In 2022, the Women’s Sports Foundation published a report addressing current status of Title IX compliance in U.S school-based sports, examining limitations as single axis law that addresses gender but not other areas intersectionality including race, identity, sexual orientation, and ability. What is presented here executive summary policy recommendations from report.

A method combining crystal plasticity (CP), the eXtended Finite Element Method (XFEM), and cohesive zone model (CZM) with traction separation law is developed for an Al-Cu-Mg alloy to predict effect of grain orientation on fatigue crack propagation (FCP) during stage ?? within a single crystal. The simulation results show that all orientations, Goss possesses largest deflection, then followed b...

Simple random walks on a partially directed version of Z are considered. More precisely, vertical edges between neighbouring vertices of Z can be traversed in both directions (they are undirected) while horizontal edges are one-way. The horizontal orientation is prescribed by a random perturbation of a periodic function, the perturbation probability decays according to a power law in the absolu...

We analyse a gathering process for a group of mobile robotic agents, identical and indistinguishable, with no memory and no common frame of reference (neither absolute location nor a common orientation). The agents are assumed to have bearing only sensing within a limited visibility range. We prove that such robots can gather to a small disk in the R-plane within a finite expected number of tim...

Previous works by the authors [Wei et al., 2003; 2004] have developed a simple bearing-only control law for a mobile robot with demonstrated convergence to a unique final pose and orientation. Here, we use a time-varying weight strategy to first draw the robot towards a known “good” starting region and then a second set of weights is used for docking. This strategy allows the robot to dock succ...
