受《周易》神秘文化影响,在中国美学看来,“气”是宇宙的原初实有,是最高的本体,“道”即混沌之“气”,宇宙万物皆由“气”所化生化合;作为宇宙万物生成的中间环节,“气”生于“道”或“太极”,是宇宙万物的共同构成质料或元素。审美创作活动中心物的感应、情景的交融离不开“气”与“气化”作用。由此,中国美学提出了“气之动物,物之感人”说:宇宙万物的生成本源为“阴阳”二气,“阴阳”二气的运行,“气”之动物,激发了万物的生长发育,自然也激发创作者的创作动机,而摇荡性情,形诸舞咏,引起审美创作。“物动心感”,引起创作者内心感动与审美域构成的原初动力是“气”。  相似文献

We are occupied with an example concerning the limit theory of the ordinary least squares estimator (OLSE) when the innovation process of the regression has the form of a martingale transform the iid part of which lies in the domain of attraction of an α-stable distribution, the scaling sequence has a potentially diverging truncated α-moment, and the regressor process has a potentially divergent truncated second moment. We obtain matrix rates that reflect the stability parameter as well as the slow variations present in the aforementioned sequences, and stable limits. We also derive asymptotic exactness, consistency, and local asymptotic unbiasedness under appropriate local alternatives for a heteroskedasticity robust Wald test based on subsampling. The results could be useful for inference on the factor loadings in an instance of the APT model.  相似文献

This article is concerned with inference for the parameter vector in stationary time series models based on the frequency domain maximum likelihood estimator. The traditional method consistently estimates the asymptotic covariance matrix of the parameter estimator and usually assumes the independence of the innovation process. For dependent innovations, the asymptotic covariance matrix of the estimator depends on the fourth‐order cumulants of the unobserved innovation process, a consistent estimation of which is a difficult task. In this article, we propose a novel self‐normalization‐based approach to constructing a confidence region for the parameter vector in such models. The proposed procedure involves no smoothing parameter, and is widely applicable to a large class of long/short memory time series models with weakly dependent innovations. In simulation studies, we demonstrate favourable finite sample performance of our method in comparison with the traditional method and a residual block bootstrap approach.  相似文献

Abstract

This essay addresses the institutional conditions of cultural studies, especially those bearing on cultural studies teaching. It does so by reviewing the history of the Open University Popular Culture course from an insider's perspective. Whereas most published accounts of this course have related it closely to the concerns of the Birmingham Centre for Contemporary Cultural Studies, this essay suggests that the two projects — while overlapping in certain respects — are more usefully thought of as distinct. Having disentangled the history of the Open University course from that of the Birmingham Centre, the author goes on to advance a more general argument concerning the politics and practice of cultural studies pedagogy. The essay's main contention in this regard is that a conception of cultural studies teaching which connects it to the cultivation of resistive practices in the classroom is incoherent. It is suggested that this now influential current of thought is best assessed as a negative outcome of the encounter between the projects of cultural studies and US liberationist philosophy.  相似文献

ABSTRACT

This article explores the domain of odors and olfaction on the island of Bohol, The Philippines. It recounts how my research interests were drawn to this domain by local preoccupations with smell as an aspect of everyday sociality, expressed in speech, modes of interaction and evaluation, and the discursive construction of ethnicities and other social kinds. Bohol's long and complex history and its place in the contemporary world entail a complex, differentiated sociocultural present, which is also reflected in the domain of odors and Boholanos' experiences thereof. Accordingly, the article makes a case for an approach to this domain that flexibly deploys basic ethnographic procedures and more formal techniques, specifically, domain and cultural consensus analysis. This dual methodology, it is argued, is sensitive to the differences between differentially positioned agents, but also demonstrates the degree of sharedness—of experience, categorical schemes, and historicity—that jointly characterize this domain. I use a partial set of results, pertaining to human body odors, to exemplify the approach and to depict a key dimension of Boholano social experience; one that speaks to the place of individuals in the local setting and to the position of the population generally in the commodified world of cosmetics.  相似文献

ABSTRACT

For a unimodal growth function f having its maximum at a critical state x c , the interval bounding the population size asymptotically is usually presented as being equal to [f ○2(x c ), f(x c )]. This interval however does not represent the maximum range within which the population size can vary, even asymptotically. The actual invariant interval containing the population size is equal to: [min(x*, f ○2(x c )), f(x c )], where x* denotes the non-zero fixed point, assumed to be unique, of the iteration of f.  相似文献
