清代中期“以礼代理”说刍议 总被引:1,自引:0,他引:1
清代中期,以凌廷堪、焦循、阮元为代表的汉学家提出了“以礼代理”说,即主张用礼学代替理学。他们认为,儒学的中心是“礼”而不是“理”,脱离了“礼”而言“理”,只能导致师心自用以及对人的具体情感的漠视。这一学说是清初顾炎武所倡导的学术方向的继续,它把人们的目光由内在精神变革转向对外在制度的关注;同时,这一学说明确反对以抽象化的“理”来约束人们的行为,它在一定程度上减轻了理学所带来的消极影响。 相似文献

A series of three experiments examined children's sensitivity to probabilistic phonotactic structure as reflected in the relative frequencies with which speech sounds occur and co-occur in American English. Children, ages 212 and 312 years, participated in a nonword repetition task that examined their sensitivity to the frequency of individual phonetic segments and to the frequency of combinations of segments. After partialling out ease of articulation and lexical variables, both groups of children repeated higher phonotactic frequency nonwords more accurately than they did low phonotactic frequency nonwords, suggesting sensitivity to phoneme frequency. In addition, sensitivity to individual phonetic segments increased with age. Finally, older children, but not younger children, were sensitive to the frequency of larger (diphone) units. These results suggest not only that young children are sensitive to fine-grained acoustic-phonetic information in the developing lexicon but also that sensitivity to all aspects of the sound structure increases over development. Implications for the acoustic nature of both developing and mature lexical representations are discussed. 相似文献

Fat women who endorsed fat acceptance (N=128) were recruited from Radiance Magazine. Relationships between objectified body consciousness (OBC), body esteem, and psychological well-being for the mostly European American sample were similar to those found in other samples. OBC was independently related to body esteem when weight dissatisfaction was controlled. Those who endorsed the need for social change in attitudes towards fat people had higher body esteem and self-acceptance, and lower body shame, than those who endorsed personal acceptance of body size only. 相似文献

The Koala Fear Questionnaire (KFQ) is a standardized self-report scale for assessing fears and fearfulness in children aged between 4 and 12 years. The current article presents six studies which examined the reliability and validity of the KFQ. Study 1 (N=108) demonstrated that the visual fear scales of Koala bears as employed in the KFQ are highly comparable to the standard 3-point scales that are used in other childhood fear measures. Study 2 (N=163) provided support for the convergent validity of the KFQ in a sample of 8- to 14-year-old children. That is, the scale correlated substantially with alternative measures of childhood fear and anxiety. Study 3 (N=189) showed that the KFQ possesses good internal consistency and test-retest stability in a group of 8- to 11-year-old children. The results of Studies 4 (N=129) and 5 (N=176) indicated that the KFQ is suitable for children aged 4 to 6 years and demonstrated that the psychometric properties of the scale in younger children are highly similar to those obtained in older children. Study 6 (N=926) showed that the factor structure of the KFQ was theoretically meaningful: although the data clearly pointed in the direction of one factor of general fearfulness, spurs of the commonly found five-factor solution of childhood fear were found in the KFQ. Altogether, the KFQ seems to be a valuable addition to the instrumentarium of clinicians and researchers who are working with fearful and anxious children. 相似文献

Although much social science research has been conducted within American Indian and Alaska Native (AIAN) communities, relatively little research has been conducted by or for those communities. We describe an approach that facilitates the active involvement of AIAN communities in the research process, from conceptualizing the issues to be investigated to developing a research design, and from collecting, analyzing, and interpreting the data to disseminating the results. The Tribal Participatory Research (TPR) approach is consistent with recent developments in psychology that emphasize the inclusion of community members and the social construction of knowledge. We describe the foundations of the approach and present specific mechanisms that can be employed in collaborations between researchers and AIAN communities. We conclude with a discussion of the implications of the use of TPR regarding project timelines and budgets, interpretation of the data, and ultimately the relationships between tribes and researchers. 相似文献

This paper forms an introduction to this issue, the contents of which arose directly or indirectly from a conference in May 2001 on Corruption of scientific integrity? — The commercialisation of academic science. The introduction, in recent decades, of business culture and values into universities and research institutions is incompatible with the openness which scientific and all academic pursuit traditionally require. It has given rise to a web of problems over intellectual property and conflict of interest which has even led to corporate sponsors’ suppressing unfavourable results of clinical trials, to the detriment of patients’ health. Although there are those who see the norms of science developing to recognise the importance of instrumental science aiming at specific goals and of knowledge judged by its value in a context of application, none justifies the covert manipulation of results by vested interest.Public awareness of these problems is growing and creating a climate of opinion where they may be addressed. We suggest a way forward by the introduction of nationally and internationally-accepted guidelines for industrial collaboration which contain proper protections of the core purposes of universities and of the independence of their research. Some codes suggested for this purpose are discussed. We note that some universities are moving to adopt such codes of conduct, but argue the need for strong support from the government through its funding bodies. 相似文献

Japanese exhibits two different types of morphological processes. Some morphologically complex predicates are generated within the domain of the lexicon, whereas others are generated outside the domain of the lexicon. An elicited production task involving both types of complex predicates was administered to six Japanese children with specific language impairment (JSLI) and six children with normal language development (JNLD). The JSLI children experienced significant difficulty forming the lexicon-external complex predicates but much less difficulty with the lexicon-internal complex predicates while the performance of the JNLD children exhibited no such asymmetry. These preliminary results suggest that the deficit of SLI affects the ability to construct implicit procedural rules for morphology that are generated outside the lexicon while their lexical operations for morphology that are generated within the domain of the lexicon remain relatively unimpaired. 相似文献

This paper includes (i) a comparison of the developmental pattern of certain morphosyntactic features in normally developing (ND) Greek children with similar data from a group of children with specific language impairment and (ii) a new analysis of the differences found. The analysis is based on a minimalist notion of LF interpretability. Depending on the feature-specification of lexical items (i.e., [+/- interpretable] at LF), a different route of development follows. In addition, phonological salience of both interpretable and noninterpretable features is argued to play an important role in an account of crosslinguistic differences in both normal and exceptional development. 相似文献

Comparison of the concepts of creation from chaos and creation out of nothing ( creatio ex nihilo ) leads me to reject the latter for several reasons: it is not the biblical concept, and it presents serious conceptual, scientific, and theological problems. Chaos theology is outlined under the headings creation from chaos; chaos and contingency; chaos, evil, and creativity; chaos and incarnation; chaos and eschatology. It is shown to be well suited for the science-theology dialogue by some examples of its application to aspects of cosmic and biological evolution: initial mystery, separation and ordering; chaos and entropy; contingency and fine-tuning of the universe; purpose and progressiveness in evolution; and complexity theory and chaos events. 相似文献
