Some of them are inefficiency operations. It is important to evaluate operational efficiency of ports to reveal their position in regional competitive environment. In this study, high spatial resolution satellite remote sensing images were used to monitor ship number and plane area. The port-use prosperity index(PUI) was subsequently proposed to quantitatively describe port-use business and reveal port-use efficiency. The PUI was applied to six ports around the Bohai Sea, China. The number, scale, and plane of ships docked in these ports were easily monitored by the high spatial resolution satellite remote sensing images, and the PUI was calculated using a ship’s total plane area and length of docked coastline. The PUI is an objective and practical index for evaluating port-use efficiency. It can be used to compare differences in port use and indicate temporal port-use dynamics. The PUI values of Jingtang and Tianjin Ports were the highest(17.75 and 14.14, respectively), whereas that of Yantai Port was the lowest(8.31). The PUI values of the remaining ports were 9.0–10.70. A linear relationship existed between port throughput and PUI in the studied ports. This can forecast port throughput by monitoring and calculating PUI based on high spatial resolution satellite remote sensing images.展开更多

The present research is a conceptual study. The data were collected to analyze the entrepreneurship theories in Saudi Arabia＇s context. The data related to entrepreneurship spirit, perception of society towards entrepreneurship, and other macroeconomic indicators are collected from different research journals, websites of different corporate houses, and government sources to analyze the social entrepreneurship theories, such as failure thesis, interdependence theories, welfare state theory, supply-side theory, entrepreneurship education, etc.. The theoretical hypothesis of interdependence theory, entrepreneurship spirit, and general education and the theoretical analysis of this paper in light of Saudi Arabia are in line with the theory. But the hypothesis generated out of failure thesis theory, welfare state theory, entrepreneurship education, and individualistic and collective society culture is not in line with these theories.展开更多
