A paper by Tetsuya Kamijo, senior advisor to the deputy director of the JICA Research Institute, was published in the 2015 edition of the Journal of Environmental Information Science (Vol. 43, No.5). The paper is entitled "A Verification of Alternative Assessment using Principal Component Analysis based on Case Studies of the Japan International Cooperation Agency." The abstract on the site describes the content of the paper as follows: "Prior research suggested that principal component analysis was effective as an alternative assessment technique in terms of clarity of reasons for selecting the most suitable option, low arbitrariness, verification of analysis results and easiness of technique. This study aimed to apply this analysis to the 15 cases of alternative assessment that the Japan International Cooperation Agency prepared, in order to verify the adequacy of a regular assessment methodology."
