[Method] The value field of fitness of heterozygote was investigated by constructing mathematical models, to clarify the internal relations of the four theories on natural selection unit. [Result] According to mathematical modes constructed in the study, only the mutated genes meet the requirements of natural selection on heterozygous and homozygous aspects, as well as show high fitness in heterozygous condition, could the mutated genes be kept, giving consideration to both individual and population adaptation. Thus, this methodology theoretically inte- grates the theories of individual selection, collective selection, and genetic selection as well as Kimura＇s neutral theory of health information. [Conclusion] The result of this study suggested that the four theories on natural selection unit can co-exist, and share common premises.展开更多

These problems include ambiguities in Nietzsche＇s attitude to truth, and the question of how well he can carry through his project of affirming the individual on the basis of a creative reinterpretation of experience. I maintain that Novalis understands language and cognition to be tropic in a similar way as Nietzsche does, and that these writers provide similar critiques of discursive reason on the basis of what they view as its stultifying rigidity and misleading claims to a ＂literal＂ form of objectivity. However, I argue that Novalis avoids Nietzsche＇s difficulties by maintaining that a creative element in cognition does not rule out a variant of a correspondence notion of truth. Although Novalis＇ account thus falls foul of Nietzsche＇s goal of providing an immanent affirmation of human experience, the comparison shows that a Nietzschean attempt to provide a convincing model of individual self-affirmation should integrate a more positive role for trope, which can support a satisfying conception of the value of human creativity.展开更多

In an effort to use a fine-grained metaphor-analysis approach（ e. g. , Lakoffand Johnson 1980, 1999） to revisit the input hypothesis, this study looks into its thrust--the causal effect of comprehensible input upon comprehension--in the hope of charting out its hidden organization. By discovering a theme of CAUSATION pivoted on space-based metaphors and metonyrnies, the present study brings to relief two fallacies committed in the input hypothesis. First, the heavy dependence on the prototypicaUy physical-spatial hierarchy leads to a red-herring fallacy, whose inconsistency defies rather than supports its statement about comprehensible input as the overriding cause. Second, although there is no denying that comprehensible input is a significant source of language gains, to enthrone it as the sole causal variable to the exclusion of all the other important variables, especially the agency of the 1.2 learner who should have been positioned in the spotlight in the first place, is another fallacy of immense magnitude.展开更多
