Abstract
Purpose
This paper aims to develop an efficient algorithm combining straightforward response surface functions with Monte Carlo simulation to conduct seismic reliability analysis in a systematical way.
Design/methodology/approach
The representative slip surfaces are identified and based on to calibrate multiple response surface functions with acceptable accuracy. The calibrated response surfaces are used to determine the yield acceleration in Newmark sliding displacement analysis. Then, the displacement-based limit state function is adopted to conduct seismic reliability analysis.
Findings
The calibrated response surface functions have fairly good accuracy in predicting the yield acceleration in Newmark sliding displacement analysis. The seismic reliability is influenced by such factors as PGA, spatial variability and threshold value. The proposed methodology serves as an effective tool for geotechnical practitioners.
Originality/value
The multiple sources of a seismic slope response can be effectively determined using the multiple response surface functions, which are easily implemented within geotechnical engineering.

Abstract
Purpose
The purpose of this paper is to re-examine the statement of Peloza (2006) that enterprise corporate social responsibility (CSR) investment provides a protection efficacy similar to insurance.
Design/methodology/approach
This study uses the event study method and data from the 2008-2010 China listed company social responsibility report and the Taiwan Economic Journal.
Findings
The authors find that the insurance-like effect of CSR investment also exists in China. Both short- and long-term CSR investments of Chinese companies provide this efficacy to corporate stock prices. The authors also find diminishing marginal insurance-like effects in China market.
Originality/value
The CSR investment of firms in China can reduce company stock-price loss when negative events occur. The authors therefore obtain a better understanding of the value of enterprise CSR investment.
