紧缩论,证明与保守性

紧缩论者主张真谓词表达了一种逻辑概念,它的全部意义都体现在所有塔斯基式的T-语句中。Shapiro近来论证说,将紧缩论的公理添加到一阶皮亚诺算术公理系统(PA)中,在该扩张理论中能够证明PA的可靠性,并在此基础上证明PA的一致性,这表明紧缩论不具有保守性,因此真谓词不是紧缩的。本文论证,扩张理论预设了反射原则,这导致它推出了更多的东西,而反射原则是可证性谓词定义的推论,这才是造成扩张理论非保守性的真正根源。针对紧缩论的非保守性论证因此失效了。     

Who Says What: Election Coverage and Sourcing of Child Care in Four Canadian Dailies

Advocates have called for universal, quality child care in Canada since the 1970s, but the issue seldom appeared to acquire political urgency. The 2006 election campaign seemed different. The governing Liberals promised to devote billions to a nascent national program. The Conservatives promised parents a cash allowance for young children. Child care seemed to be emerging as a significant issue in a political campaign. How was ECEC written about before, during and after Canadian election campaigns? Who is quoted and how? Our project mapped articles about child care in four major Canadian dailies between 2000 and 2008. We found that coverage spiked in 2000 and 2005–2006—during federal elections. Coverage nearly doubled in 2005–2006 in all but one paper. Using content analysis, we compared coverage of child care and sources in the 55 days before the start of campaigning, 55 days of campaigning, and 55 days following the 2006 election. We mapped and compared who said what, and how about child care policy and related issues, in Canada. We found: (1) that newspapers’ ideological slants are apparent in their choice of sources and focus; and (2) that more importantly, despite ideological differences, political figures outnumbered activists, parents and child care providers. With only minor variations across the newspapers, the voices of parents and child care activists were marginal especially in the 55 days of campaigning.     

Attending to objects: Endogenous cues can produce inhibition of return

Inhibition of Return (IOR) is effective in a wide range of experimental settings but has proven elusive under conditions of volitional (endogenous) attentional control. This result may be due to a continuing attentional bias towards the cued location. Here we ask whether IOR can be unmasked under endogenous cueing conditions when a predictive cue prevents such a bias. In Experiment 1, a central arrow directed attention endogenously to one end of a rectangular object. Attention initially radiated to an unpredicted location in the object but IOR later impaired target detection at that location. In Experiment 2, attention was directed endogenously to a dynamic object. While target detection was facilitated at a subsequent (and predicted) location of the rotating object, detection-latencies at its original location were slowed. Together the results show that it is possible to produce IOR using endogenous cues.     

Kierkegaard's anti-ecclesiology: the attack on ‘Christendom’, 1854–1855

Abstract

This article examines Kierkegaard's attack on the Danish state church in 1854–1855, beginning with Kierkegaard's rejection of Martensen's application of the term ‘witness to the truth’ to the recently deceased primate of the Danish church, J. P. Mynster. For Kierkegaard a witness to the truth is the person who emulates Christ's life of suffering and lives in poverty and abasement. It is an insult to the memory of the ‘glorious ones’ of the past to apply this term to the worldly, self-serving Mynster. The article goes on to consider Kierkegaard's conception of the heterogeneity of Christianity with the world, before considering Kierkegaard's rejection of the state church as a confusion of church and state which eliminates the Imitatio Christi essential for genuine Christian existence. The failure of the state church and its clergy to live according to the New Testament means that they are an abomination, and public worship is a blasphemous insult to God. The paper concludes by considering what lessons can be learned from Kierkegaard's radical anti-ecclesiology.     

Cognitive basis of individual differences in speech perception,production and representations: The role of domain general attentional switching

This study investigated whether individual differences in cognitive functions, attentional abilities in particular, were associated with individual differences in the quality of phonological representations, resulting in variability in speech perception and production. To do so, we took advantage of a tone merging phenomenon in Cantonese, and identified three groups of typically developed speakers who could differentiate the two rising tones (high and low rising) in both perception and production [+Per+Pro], only in perception [+Per–Pro], or in neither modalities [–Per–Pro]. Perception and production were reflected, respectively, by discrimination sensitivity d′ and acoustic measures of pitch offset and rise time differences. Components of event-related potential (ERP)—the mismatch negativity (MMN) and the ERPs to amplitude rise time—were taken to reflect the representations of the acoustic cues of tones. Components of attention and working memory in the auditory and visual modalities were assessed with published test batteries. The results show that individual differences in both perception and production are linked to how listeners encode and represent the acoustic cues (pitch contour and rise time) as reflected by ERPs. The present study has advanced our knowledge from previous work by integrating measures of perception, production, attention, and those reflecting quality of representation, to offer a comprehensive account for the underlying cognitive factors of individual differences in speech processing. Particularly, it is proposed that domain-general attentional switching affects the quality of perceptual representations of the acoustic cues, giving rise to individual differences in perception and production.     

病人自主性与家庭本位主义之间的张力

在中国几千年小农经济和传统文化背景下,个人利益、个人权利一直被置于家庭之下,个人自主性被包含在家庭自主性之内,表现为一种家庭本位主义。源自西方历史、文化的知情同意移植到中国后,受传统文化观念的影响,中国人对知情同意的认知、理解以及实践方式均不同于西方人。这种不同集中表现在人们对家属同意权的认可。以个人本位主义为背景的病人自主性与中国文化中的家庭本位主义之间存在张力。对知情同意在不同文化环境中不同践行方式,应以文化宽容主义的态度对待之。     

论医护人员对患者隐私权保护的注意义务

侵害患者隐私权的医疗纠纷频发,很大原因是医护人员未履行对患者隐私保密的高度注意义务。从具体案例出发,就医护人员对患者隐私权保护的注意义务进行阐释,探究该义务产生的根源,对违反该注意义务的责任进行评析。以期提高医护人员对患者隐私权保护注意义务的重视,减少相关医疗纠纷的发生。
