Iran attempts to expand the non-oil exportsfor diminishing the dependency on oil export income. This research tries to examine the export and trade balance of Iran's agricultural sector. Accordingly, the gravity model was used for export, applying panel data from 1997 to 2017. Also, the trade balance of Iran's total agricultural and the related sectors’commodities was examined. It should be noted that for the trade balance, time series data from 1978 to 2018 were used. The results of the gravity model show a negative effect for the variable of distance. The coefficients of Iran’s per capita GDP and also the GDP of trading partners are positive, as expected. It was found that a one percent increase in the per capita GDP of Iran causes a rise of 3.42 percent in the export of agricultural products; however,that of importing countries haslow statistical significance. Based on the coefficient obtained for the population, an increase in the population of the importing countries raises the demand for Iran's agricultural products.The degree of trade openness revealed a positive and significant effect on the export of agricultural products. The coefficient for the real exchange rate was found to be around 0.9 percent. It was also found that the volatility of the exchange rate is related directly to the export of agricultural products. Comprehensive sanctions have a negative and significant effect, while less restricting sanctions have an insignificant effect on the export of agricultural products. The global economic crisis has also had a dampening effect on exports. For trade balance, the results show that the value added of the agriculture has a positive effect on the trade balance of entire agriculture and sectors. The real exchange rate has a negative effect on the trade balance of agricultural commodities as a whole and livestock and agronomy sectors, confirming the J-Curve theory while it was not supported for the horticultural sector. Also, the variable of exchange rate volatility was included in the model using two measures of positive and negative series of exchange rate changes and the Autoregressive Conditional Heteroskedasticity (ARCH) effect, but their effect on the trade balance was not the same in terms of both the direction and statistical significance. The trade openness for the agricultural and horticultural sector was found with a positive coefficient, indicating that their production is based on comparative advantage. However, for the sectors of agronomy and livestock, it illustrated a negative effect. Sanctions have also harmed the trade balance.

Purpose: This study intended to investigate the effectiveness of personal wisdom therapy approach in reducing internet addiction in adolescent female students. Method: The present study was a semi-experimental study and its statistical population was 200 adolescent female students studying in high schools in the city of Hamadan in the academic year 1399-1400 from which 34 female students, selected based on convenience sampling procedure, were randomly divided into experimental and control groups. The participants in the experimental group received 10 training sessions using a wisdom-therapy approach. In order to assess the participants’ internet addiction, the internet Addiction Scale developed by Young (2007) was used. The effect of the provided trainings was assessed using pre-test, post-test and two-month follow-up. In order to analyze the obtained data, a set of ANCOVA was run. Findings: The results revealed that personal wisdom-therapy had a statistically significant positive effect on reducing the level of internet addiction among adolescent female students. Impact and implication statement: since wisdom therapy has been effective in reducing internet addiction, all those involved in education, including teachers and school principals can design wisdom-based lessons and programs to help students in this regard and improve the quality of education.
