To voice his minority subjectivities, Wittman Ah Sing, the protagonist in Tripmaster Monkey: His Fake Book, needs to protest the emasculated stereotype culturally applied to him, a Chinese American man, in a way of changing his identities. This multiple-faced Wittman Ah Sing manifests Kingston's objection to any singular or fixed subjectivity of Chinese Americans in her anti-racist posture.展开更多

A total of 69 strains of vibrios were isolated from all samples examined. The strains, along with 10 reference strains were classified with the technique of numerical taxonomy bared on 54 characters and 62 of the 69 strains fell into 5 major phena, identified as V. paraheamolyticus (30 strains), V. alginoloticus (23 strains), V. choloerae (3 strains), V. harveyi (2 strains) and V. fluinalis (4 strains). Among them, V.paraheamolyticus and V. alginolyticus were the predominant species in the fishes, shellfishes and the coastal waters of Hong Kong and comprised 43. 5 % and 33. 3 % of the total Vibrio spp. isolates respectively. Meanwhile, 3 strains of non-Ol V. cholerae were isolated from oyster and it was the first time to record V. cholerae non-Ol in seawater or from shellfishes in Hong Kong. These results highlighted the potential risks of food poisoning associated with raw or undercooked seafood.展开更多
