The label ＂Asian American literature＂ is so instrumental in instituting the literature, can also regulate creativity. As a strategic term and group identification, ＂Asian American＂ lends itself to the illusion of unity and homogeneity. Scholars differ in the way they elect to demarcate Asian American literature. One of the fundamental barriers to understanding and appreciating Asian American literary expression has been the existence of race stereotypes about Asians in American popular culture. For many Asian American writers, ethnic authenticity is a necessary but weak choice Most early immigrant writers write to challenge the negative view of Asia in the West and see themselves as ambassadors of goodwill to the West. The purpose is to mark difference as exotica and appeal to the benign curiosity of the Western readers while appeal to notions of universal humanity. This type of strong ethnic quotient writing continues to exist in various guises even today. The trade publishers have a predilection for Asian American personal narratives that stress the ＂model minority＂ discourse, ＂good workers＂ image, and Asian Americans＇ ability to accommodate to the basic rules of American society. Asian American writers never stop attempting to build bridges. But we should remind ourselves that boundary crossing must not be merely an aesthetic and intellectual exercise .展开更多

The frequency picking up sweet-corn grains to take into the mouth by either hand of monkeys was counted directly at the feeding ground where sweet-corn grains were scattered for monkeys. Among the 20 monkeys examined, 8 were right-handed, 8 were left-handed, and 4 were ambilateral. The results indicated the prevailed hand preference on individual level but not either trends of left- or right-hand preference on population level. The trend toward a higher proportion of left-handed monkeys found in Japanese and rhesus monkeys was not found. Some other characteristics found in moor monkeys are discussed in comparison with those previous findings in Japanese and Tibetan macaques in order to evaluate variations within the genus Macaca展开更多

By providing a conceptual framework based on the combination of environmental awareness theory and tourist perception theory, and a SEM-based methodology, an in-depth analysis of the influence mechanism was carried out in the Qinghai Lake area of Qinghai province. Results show that there exist differences in the ways environmental awareness influences perceived gains and perceived losses, and the influence coefficient of the former is higher than that of the latter. The perceived gains may promote environmentally friendly behaviors, while the perceived losses have an adverse impact on such behaviors. Moreover, the strength of the adverse impact of the latter is less than the strength of the positive impact of the former. The mediating effect of perceived quality was confirmed in the EA（environmental awareness）-EB（environmental behavior） nexus, within which the influence of tourist environmental awareness on environmentally friendly behavior could be transformed. The mediating effect of perceived quality in the perceived-gains model was more obvious than that in the perceived-losses model. This study highlights the importance of understanding the foundations of environmental behavior related to environmental awareness and tourist perceptions.展开更多

They actually form the basis for many animal complex behaviors. Recent years have seen significant progresses in disclosing the molecular and neural mechanism underlying animal innate preferences, especially in Drosophila. In this review, I will review these studies according to the sensory modalities adopted for preference assaying, such as vision, olfaction, thermal sensation. The behavioral strategies and the theoretic models for the formation of innate preferences are also reviewed and discussed.展开更多

We acclimated hatchling soft-shelled turtles Pelodiscus sinensis under three thermal conditions （10, 20 and 30~C） for 4 weeks, and then measured selected body temperature （Tsel）, critical thermal minimum （CTMin） and maximum （CTM^x）, and locomotor performance at different body temperatures. Thermal acclimation significantly affected thermal preference and resistance of P sinensis hatchlings. Hatchling turtles accli- mated to 10~C selected relatively lower body temperatures and were less resistant to high temperatures than those acclimated to 20~C and 30~C. The turtles＇ resistance to low temperatures increased with a decreasing acclimation temperature. The thermal re- sistance range （i.e. the difference between CTM^x and CTMin, TRR） was widest in turtles acclimated to 20~C, and narrowest in those acclimated to 10~C. The locomotor performance of turtles was affected by both body temperature and acclimation tem- perature. Hatchling turtles acclimated to relatively higher temperatures swam faster than did those acclimated to lower temperatures. Accordingly, hatchling turtles acclimated to a particular temperature may not enhance the performance at that temperature. Instead, hatchlings acclimated to relatively warm temperatures have a better performance, supporting the ＂hotter is better＂ hypothesis.展开更多

The aims of the study were to explore factors affecting farmers’ implementation of WFF practices on Sado Island, Japan and to consider the policy implications of disseminating such practices. All 5010 farming households on Sado Island, who are distributing rice to Japan Agricultural Cooperatives （JA）, were surveyed. In total, 2231 households responded to the questionnaire （response 44.5%）. By comparing the attitudes, beliefs, and attributes of non-certiifed versus certiifed farmers, we identiifed key factors affecting farmers’ implementation of WFF practices. Compared with non-certified farmers, certified farmers： （i） showed a greater interest in biodiversity and the ifnancial beneifts of WFF; （i） had a larger number of certiifed farmer friends; （ii） felt many more pressures and expectations from consumers, in particular; and （iv） were not hampered by bad labor or farmland conditions when implementing WFF practices. To further disseminate WFF practices in Sado, we suggest that the information on the effectiveness of WFF on paddy ifeld biodiversity is used in public education, and opportunities for interchanging opinions are set up between non-certiifed and certiifed farmers, as wel as between farmers and consumers.展开更多
