The deformation characteristics of the crust before the earthquake were discussed through inter-station baseline time series analysis and the strain time series analysis in the epicentral region. The results show that a trend turn of the baseline movement state around the epicenter region occurred after 2014,and the movement after 2014 reflects an obvious decreasing trend of compressional deformation.During this period,the stress field energy was in a certain accumulation state. Since the beginning of 2014,the EW-component linear strain and surface strain rate weakened gradually before the earthquake. It shows that there was an obvious deformation deficit at the epicentral area in the past two years,which indicates that the region accumulated a high degree of strain energy before the earthquake. Therefore,there was a significant background change in the area before the earthquake. The results of the study can provide basic research data for understanding the seismogenic process and mechanism of this earthquake.展开更多

Nonetheless, the research in this domain has been growing at an impressive speed in recent decades. Analysis of corporate governance has become a key factor in our understanding of corporations in recent years, and an indicator of investor confidence in the decisions is taken by the managers and board of directors of the listed companies. This paper evaluates both qualitative and quantitative techniques that are implied in corporate governance field. The methodological techniques are a key element of the research process In this article, the authors developed a content analysis of the published empirical research in order to expose a possible gap between what is currently done versus what needs to be done in terms of the techniques of data analysis used in corporate governance field. The results of this study allow the authors to draw some valuable conclusions regarding the trends in methodological techniques that support the evolution of corporate governance. The findings indicate that, in general, the researchers are inclined to more sophisticated quantitative techniques. However, the use of qualitative techniques remains preponderant among corporate governance scholars.展开更多

In order to forecast the trend of AUD, this essay examines the exchange rate of AUD in then years from March of 2000 to March of 2010, and argues the factors which create these trend changes. By means of secondary research and graphs analysis, the relevant evidence and argument was selected into four terms below： relative raw materials prices changes, relative domestic price level and Import-Expert changes, relative interest rate changes, and other factors.
