In this paper, the process of IT project decision and implementation is fully analyzed, the real options that may be embedded in an IT project are identified, and a real option analysis (ROA) method is proposed for evaluation of an IT project under uncertain business environment. ROA employs Black-Scholes expansion model and cancels the assumption that the cost of project is certain. The numerical example manifests that the ROA can better evaluate IT project and select the IT investment alternative. Finally, a road map is provided to help selecting the suitable evaluation method to make IT investment decision.展开更多

In this paper, the proportion of independent directors in the board of directors, and the actual condition, compensation, and duties performing of independent directors are analyzed by taking A-share listed companies in Shanghai Stock Exchange as an example, so that the current implementation situation of the independent director system in China＇ s listed companies is analyzed deeply through the empirical method. Finally, suggestions for its imorovement are orooosed.展开更多

Also the role that capital is expected to play in the economy is different in two economic systems. One of the key elements in creation of the capital （capital formation） is interest rate. In Islam interest is strictly forbidden. This paper reviews the concept of capital and the process of capital formation both before and after industrial revelation. In that context it also looks at the function of interest rate during the time of Prophet Mohammed and the present time.展开更多

The algorithm is tested using Greenhouse gases Observing SATellite （GOSAT） LIB data and validated using the Total Column Carbon Observing Network （TCCON） measurements. The retrieved XCO2 agrees well with TCCON measurements in a low bias of 0.15 ppmv and RMSE of 1.48 ppmv, and captured the seasonal vari- ation and increasing of XCO2 in Northern and Southern Hemisphere, respectively, as other measurements.展开更多

Under the new scheme, mainland investors can trade shares on the stock exchange of Hong Kong through local brokers, and Hong Kong investors can buy and sell stocks on the tech-heavy Shenzhen bourse. The arrangement is the second link between mainland and Hong Kong capital markets, after the Shanghai-Hong Kong Stock Connect was launched in 2014.展开更多
