This paper presents an empirical investigation on the effect of exports of non-oil goods and services on economic growth in Iran over the period 1991-2011 using Vector Autoregressive method. We also analyze the existing causal relationships between total factor productivity and non-oil exports. The results show that total factor productivity has direct and significant relationship with non-oil exports in long-term, it means that if total factor productivity increases, non-oil exports also increases. The results of the survey also indicate that the existing shock on non-oil exports does not have any significant impact on total factor productivity but the incoming shock on total factor productivity reduces non-oil exports during the first period. It also increases non-oil exports during the first period to the fourth period and from the fifth period; it continues until it reduces to a small amount, remains in that amount and eventually disappears.

The instrument was Rosenberg self-esteem scale [Rosenberg, M. (1965). Rosenberg self-esteem scale (RSE). Acceptance and Commitment Therapy. Measures Package, 61.]. Independent variable was 12 group sessions of self-esteem games executed among experimental group. Data was analyzed with univariate analysis of covariance. Results showed that self-esteem games in ? ? 0.05 were affected on self-esteem of children. Self-esteem game can be effective intervention for children self-esteem that with them control of factors such as time and children interactions with parent and teachers in future investigations could lead to greater confidence in its effectiveness discussed.
