The microeconomic indicators are Invested Market Capital （1MC） （US$） and the number of Total Enlisted Company （TEC） which have direct and immediate impact on the Stock Turnover Ratio （STR） of DSE and the macroeconomic indicators are Gross Domestic Product （GDP）, Gross National Income （GNI）, Gross Saving （GS）, Gross Inflation （GI）, Deposit Interest Rate （DIR）, and Gross Foreign Investment （GFI） which have indirect and long run impact on DSE portfolios. To investigate the direct impact on DSE＇s turnover ratio, the Cobb-Douglas production function is applied and to investigate the indirect and long run impact, multiple linear regression models are also applied. The estimated results are diagnosed using magnitudes of derivatives, gradient and Wald＇s coefficient restriction with respect to the macro and micro economic indicators.展开更多

The plateau with the annual raining of 438 millimeters has 169 deep and semi-deep wells with annual 36.68 million consumption and this issue has increased the research signification, in order to protect and relive the required water aquifers, there is a need to predict the underground water level accurately in different condition. In this research, by the use of balance equation and modflow software in Imamzadeh Jafar, water aquifer was analyzed within seven scenario. The underground water level evaluation for the short run periods for 2 years and middle term of 4 years and 12 years of long term was performed;and the results showed that the performance and balance of the plateau was increased due to increase of water consumption compared to the water aquifer quantity in the region that was negative. To the point that the 1, 3, 4, 5, 7 scenarios (minimum 0.17 and maximum -11.34) and 2, 6 scenarios in different timely periods show that the underground water saving volume is positive (minimum 3.64 and maximum 19.83).展开更多

All players are assumed to sit around a circle and to interact only with their neighbors. It is known that full-defection is the unique long run equilibrium as the probability of players＇ experimentation （or mutation） tends to zero in the best response dynamics. Here, it is shown that full-cooperation could emerge in the long run if one also cares for his neighbors in the best- response dynamics.展开更多
