Bacteria Edwardsiella ictaluri is a major pathogenic bacterium threatening aquatic species and seriously affecting the aquaculture industry globally. Previous studies have focused on analyzing bacteria's pathological signs and virulence on pangasius fingerlings. However, research on the virulence and pathogenicity of Edwardsiella ictaluri in the striped catfish at the fry stage is still limited.

This paper applies a four-stage data envelopment analysis (DEA) approach proposed by Fried et al. (1999) to measure the operational environment-adjusted efficiency of sixty mutual funds in Taiwan from 2006 to 2010. We adopt the approach for adjusting negative output as suggested by Lovell and Pastor (1995). In addition, the truncated regression model is used to estimate effects of environmental variables on input slacks in the second stage. The efficiency of funds initially lightly declined, rapidly rose during the financial crisis of 2008, and then gradually fell again.
