In the previous research, performance evaluation of investment funds was based on some typical hypothesis, and higher moment of the assets return was mostly neglected.

Aiming at the newest Shanghai and Shenzhen (HS) 300 index futures hedge, the empirical analyses are eventually performed for the hedge strategies, thus validating the application of these different estimation methods in China's market. The results revealed in the current study show that the HR obtained by the ordinary least squares (OLS) model is maximal and the out-of-sample hedging performance is the best; however, the hedging effectiveness is not sufficiently stable for both the out-of-sample and in-sample estimation. In addition, the in-sample hedging performance accomplished through the bivariate vector autoregression (B-VAR) model is superior to those achieved via other methods.

In order to protect city from intentional threats, the urban defense engineering has become an important part of urban planning and construction.

More importantly, the macro-level study of defense resource allocation should be given more considerations. In this study, a resource allocation model focusing on urban defense under the situation with intentional attacking is developed. In this resource allocation model, the rationality level of attackers, the interrelation among targets and other related problems under intentional attacks are all considered. Besides, this model is also validated by using an example, and in this example, the impact of several important parameters have been discussed. It is shown that the expected loss of the optimized resource allocation plan derived from this model is smaller than that of the population proportion-based allocation plan and average-based allocation plan. It also shows that the correlation coefficient of targets has a significant impact of the defense resource allocation.
