The aim of this study is to evaluate the impact of violent computer games on the self-concept of second grade junior high school students in Band...

Objective: Previous research has shown that attentional bias towards game-related stimuli is a significant factor in the etiology, maintenance and severity of Internet Gaming Disorder (IGD). Therefore, interventions targeting attentional bias towards game-related stimuli, can potentially ameliorate this disorder. The aim of the present research was to examine the effectiveness of online Attenti...

Methods:  The current study was applied in terms of purpose and in terms of the nature of the data, it was semi-experimental with a pre-test-post...

The domination game is played on an arbitrary graph $G$ by two players, Dominator and Staller. It is known that verifying whether the game domination number of a graph is bounded by a given integer $k$ is PSPACE-complete. On the other hand, it is showed in this paper that the problem can be solved for a graph $G$ in $mathcal O(Delta(G)cdot |V(G)|^k)$ time. In the special case when $k=3$ and the...

coalitional game deals with situations that involve cooperations among players, and there are different solution concepts such as the core,the shapley value and the kernel. in many situations, there is no way to predict the payoff functions except for the expert experiencesand subjective intuitions, which leads to the coalitional game with fuzzy payoffs. within the framework of credibility theo...
