Prime Minister Koizumi’s six consecutive annual visits to Yasukuni shrine played a key role in initiating a new phase of domestic
citizen political mobilization not seen since the early 1970s. This paper is based on field research during the Koizumi years
(2001–2006) centering on domestic groups that conduct activities in “protection” of or “opposition” to Yasukuni shrine. As
a study of street-based politics, this paper seeks to uncover the processes, strategies, and outcomes of citizen responses
to elite political action at Yasukuni Shrine as well as explore meaning of their actions within the context of Japan’s democratic
polity.
Brian Masshardt is Lecturer, Musashi University, and a Ph.D. Candidate, University of Hawaii-Manoa, whose research addresses the political aspects of Yasukuni in the context of domestic politics and citizen’s movements. His doctoral dissertation, entitled ‘Democracy and Yasukuni: Citizen Reaction to political action at Yasukuni Shrine, 2001–2006’ has served as the basis for conference presentations on Yasukuni and its attendant controversies. 相似文献

A simple, quick, selective, sensitive, and effective field-friendly method capable of being used by nonexperts has been developed for detecting mitragynine in Mitragyna speciosa (kratom) using surface-enhanced Raman spectroscopy (SERS). Over 100 samples and blanks (known to be either positive or negative for the presence of mitragynine) were examined in duplicate using five identical handheld Raman spectrometers, which provided a data set of over 1,000 examinations. Based on the results of these analyses, the method yielded a true-positive rate of 99.3%, a true-negative rate of 97.9%, a false-positive rate of 2.1%, and a false-negative rate of 0.7%. The average minimum detectable concentration (Cm) of mitragynine that reproducibly yielded a match for one of the library spectra on all five instruments was determined to be 342 ng/mL (ppb). This Cm value is a conservative estimate considering that the extraction process was not fully optimized by this study, which was not necessary since the Cm value achieved was well below typical mitragynine concentrations in kratom (1.3–2.3%). The method is ideal (i) for prioritizing samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify mitragynine and (ii) for field use at international mail facility (IMF) satellite laboratories to help interdict kratom and prevent this dangerous product from reaching the U.S. supply chain. 相似文献
