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 study was done using two flavors of light quarks and with a series of β and ma at the lattice size 24×122×6. The calculation was done in the Taylor expansion formalism. We are able to calculate the first and second order derivatives of ψψ in both isoscalar and isovector channels. With the first derivatives being small, we find that the second derivatives are sizable close to the phase transition and that the magnitude of ψψ decreases under the influence of finite chemical potential in both channels.展开更多
