A new semantic paradox developed by Richard Heck and relying on very minimal logical and truth‐theoretic resources is rehearsed. A theory of truth restricting the structural metarule of contraction is presented and some of the theory's relevant features are made explicit. It is then shown how the theory provides a principled solution to the paradox while preserving the extremely compelling truth‐theoretic principles at stake, thus bringing out a significant advantage that the theory enjoys over virtually all other non‐dialetheic theories. It is finally argued that such advantage is amplified by theoretical considerations made available by the adoption of a correspondentist perspective in the philosophy of truth.  相似文献

From about the fourth to the tenth century Buddhist monks in China engaged in formal, semi-public, religious disputation. I describe the Indian origins of this disputation and outline its settings, procedures, and functions. I then propose that this disputation put its participants at risk of performative contradiction with Buddhist tenets about language and salvation, and I illustrate how some chinese Buddhists attempted to transcend these contradictions, subverting disputation through creative linguistic and extra- linguistic strategies.  相似文献

阵发性心房纤颤与持续性心房纤颤同样面临着缺血性脑卒中风险,而关于阵发性房颤是否需要华法林抗凝治疗是目前争论热点问题。阵发性房颤是否抗凝治疗使患者面临着严重出血或血栓栓塞风险。循证医学论证了阵发性房颤抗凝治疗必要性及风险性,并且由于阵发性房颤患者有着不同的脑卒中及出血风险,个体差异的绝对性和多样性客观上要求对患者进行风险/效益比评估,在循证医学基础上进行个体化治疗。  相似文献

Cognitive reserve (CR) allows individuals to maintain cognitive functionality even in the presence of pathologies. The compensation hypothesis suggests that CR plays an indirect role between age and cognitive decline, contrasting the negative effect of ageing on cognition. We test this hypothesis in an unselected and consecutively enrolled sample of memory clinic attendees (n = 134) who completed the CR Index questionnaire and three neuropsychological tests assessing global cognition (MMSE, FAB, CDT). Participants were divided into two groups based on standard diagnostic criteria (DSM-5): those who were cognitively impaired (n = 92) and those who were preserved (n = 42). A principal component analysis was used to extract a composite measure of global cognitive functioning from the three neuropsychological tests, and mediation analysis was used to examine the relationship between CR, age and global cognitive functioning in the two groups. Results revealed that: (i) age had a significant direct negative effect on the global cognitive score in both groups; (ii) the three socio-behavioural proxies of CR together suppress the direct negative relationship between age and global cognitive score in cognitively impaired patients but not in cognitively preserved participants. This study confirms the association between CR, age and cognition and allows us to validate its role in a population with cognitive impairment and extend findings to a low-to-middle educated population. These results hold important implications for public health and wellness promotion, emphasising the beneficial role of maintaining healthy and active physical, cognitive and social lifestyles.  相似文献

欣赏音乐是一种审美的体验活动,不同的音质会使人产生不同的感受。为探究音乐和EEG的关系,本文选用音乐《黑人舞曲》,运用主成分分析等方法,研究了11位在校大学生在欣赏不同音质音乐时的EEG特征。结果发现:在欣赏不同音质音乐时大脑皮层右颞等处快波功率差异显著。大脑对音乐的精细加工与大脑右颞等区的电活动密切相关。  相似文献

Redundancy analysis an alternative for canonical correlation analysis   总被引:12,自引:0,他引:12  
A component method is presented maximizing Stewart and Love's redundancy index. Relationships with multiple correlation and principal component analysis are pointed out and a rotational procedure for obtaining bi-orthogonal variates is given. An elaborate example comparing canonical correlation analysis and redundancy analysis on artificial data is presented.A Fortran IV program for the method of redundancy analysis described in this paper can be obtained from the author upon request.  相似文献

A new method to estimate the parameters of Tucker's three-mode principal component model is discussed, and the convergence properties of the alternating least squares algorithm to solve the estimation problem are considered. A special case of the general Tucker model, in which the principal component analysis is only performed over two of the three modes is briefly outlined as well. The Miller & Nicely data on the confusion of English consonants are used to illustrate the programs TUCKALS3 and TUCKALS2 which incorporate the algorithms for the two models described.  相似文献
