β_2-糖蛋白I依赖性自身抗体与自然流产的关系 总被引:1,自引:0,他引:1
为探讨β2-糖蛋白I依赖性自身免疫抗体对自然流产病因诊断价值。将59名自然流产患者作为研究组,同时选择29名正常妊娠的产妇作为对照组。结论显示检测抗磷脂抗体能提高对自然流产患者病因诊断,β2-糖蛋白I依赖性抗心磷脂抗体的特异性较单纯抗心磷脂抗体的特异性高,诊断妊娠丢失的病因更准确。 相似文献

“修辞立其减”本为孔子读《易》解经之语,但它却对后世的文学评论及修辞学产生了深刻影响,高频率的使用还使它凝结为词——“修辞立诚”。如此,“修辞”与“立诚”在结构上成为平行并列的两个词。但从修辞角度看,二者则有密切的从属关系:“诚”内“辞”外,“诚”主“辞”从,“辞”以“诚”存。“诚”在儒家思想中的主导地位也说明,修辞应以“诚”为本,“辞”要服从并服务于“诚”。所谓“修辞立其诚”,是指以“诚”为前提并以“诚”为主导的“修辞”。 相似文献

作为当代心智哲学九大问题之一的他心问题,肇始于Descartes主义对心身关系的认识。问的是:我们能否知道以及怎么知道他人有心,亦即有思想、经验和情感等?对于他心问题的解决方案,20世纪90年代以来,随着现当代科学技术(尤其是神经生物学、认知神经科学和大脑测试技术等)的深入发展,哲学家与心理学家的知识联姻和交叉合作研究,提供了关于他心问题的若干重要成果和实证资料。他心问题不再成为"理论的死角"。当代社会认知神经科学的出现(social cognitive neuroscience,SCN,2000),在科学方法论上更加关注对社会性心智现象的神经机制考量,一系列研究成果都为揭示他心问题提供了科学旁证。这不仅说明了认识他心的可能性,而且表明了通向认识他心方式的多样性,物理学的方法并不是与他心相隔绝。本文尝试从社会认知神经科学的最新研究进展:镜像神经元系统,他知与自知、他心知觉和再认的社会标记、他心社会判断和归因入手来论证他心问题的可释性,为他心问题的论证提供一条多学科交叉研究的新进路。 相似文献

基于"物理符号系统假设"的传统人工智能采信了低阶结构不连续的思想,将概念化与概念的语义基础分离,把对思维过程的模拟看作是能用形式化方法来实现的。但事实证明,这种后验性方法存在理论和实现上的双重危机,要完成有实际意义的、有创新性的智能行为丰富的语义是必需的,这使语义问题成为人工智能不同应用分支中的焦点,它包括语义获取、表达和使用三个方面。而要实现对语义问题的认识和解决就必须把它和其它智能行为作为一个连续的、相关的、不可分割的认知结构进行完整地考察,以系统的观点来看待智能模型的构造问题。这个认知结构统一性的基石就是基于神经生理基础的、以知觉的心理生理学解释为依据的、对语义的直接表达,这为统一以神经系统动力学为模型的其它各种智能行为提供了基础。 相似文献

Values are guiding principles in our life. While some studies found spiritual values to be “healthier,” Sagiv and Schwartz (Eur J Soc Psychol 30:177–198, 2000) showed that people holding non-spiritual values were higher on affective well-being. We examined the predictive power of these two types of values with a longitudinal data set collected from Chinese students mainly in Hong Kong. Structural equation modeling revealed that spiritual values (as well as family income) positively predicted quality of life a year later. Non-spiritual, self-enhancement values, did not show any association. Results suggest that developing spiritual values may promote well-being through enabling individuals to find meaning and purpose in life. 相似文献

Mortality salience and evaluations of in‐group versus out‐group critics: The role of criticism legitimacy and perceived threat

Significant terror management research has examined the impact of mortality salience on evaluations toward in‐group versus out‐group and attitudinally similar versus dissimilar others. However, relatively little research has examined evaluations when group membership is disentangled from attitude similarity. The current research examined the impact of mortality salience on evaluations toward in‐group and out‐group critics when people are less likely to rely on group membership as a heuristic. In Experiment 1, the results showed that in the control condition, participants rated an in‐group member who provided unjustified criticism more positively than an out‐group member who provided the same criticism. Under mortality salience, the reverse occurred: An in‐group member who provided unjustified criticism was rated more negatively than an out‐group member. Experiment 2 showed that under mortality salience, the derogation of an in‐group critic who provided unjustified criticism was mediated by perceptions of threat. Implications for reactions to group‐directed criticism as well as mortality salience effects are discussed. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

To learn words, infants must be sensitive to native phonological contrast. While lexical tone predominates as a source of phonemic contrast in human languages, there has been little investigation of the influences of lexical tone on word learning. The present study investigates infants’ sensitivity to tone mispronunciations in two groups of infants. For one group (Chinese learners), tone is phonemic in their native language, and for the second group (English learners), tone is non‐phonemic and constituted suprasegmental variation. In Experiment 1, English learners were trained on novel word–object pairings and tested on their recognition of correct pronunciations, tone and vowel mispronunciations of these words at 18 and 24 months. In Experiment 2a, bilingual English‐Chinese learners were tested on a similar task translated into Chinese at the same age intervals. Results demonstrate that non‐tonal learners treated tonal and vowel substitutions alike as mispronunciations at 18 months but only treated vowel substitutions as mispronunciations at 24 months. Tonal learners treated both tonal and vowel substitutions as mispronunciations at both ages. In Experiment 2b, bilingual non‐tone language learners were tested on the same set of tasks replicating a similar set of results as monolingual non‐tone language learners (Experiment 1). Findings point to an early predisposition to treat tone as a defining characteristic of words regardless of its lexical relevance at 18 months. Between 18 and 24 months, learners appear to ascribe lexical relevance to tone in a language‐specific manner. The current study identifies the influences of tone variation on memories for newly learned words and the time period during which lexical tone – a highly frequent constituent of human languages – actually becomes lexical for early learners. Findings are contextualized with prevailing models of the developing lexicon. 相似文献
