A Contextual-Hierarchical Approach to Truth and the Liar Paradox 总被引:2,自引:1,他引:1
This paper presents an approach to truth and the Liar paradox which combines elements of context dependence and hierarchy. This approach is developed formally, using the techniques of model theory in admissible sets. Special attention is paid to showing how starting with some ideas about context drawn from linguistics and philosophy of language, we can see the Liar sentence to be context dependent. Once this context dependence is properly understood, it is argued, a hierarchical structure emerges which is neither ad hoc nor unnatural. 相似文献

医学伦理学是否可教及其他--关于医学伦理学教育的再思考 总被引:1,自引:0,他引:1
医学伦理学是否可教?如果可教,应该教规范还是教价值?如何拉近医学伦理学教育与现实的距离?怎样评价医学伦理学教学的效果?不仅是临床医生和卫生管理工作者,即使作为医学伦理学研究工作的学者也都对这些问题存在着不同程度的误解,这影响了医学伦理学学科地位的确立. 相似文献

Understanding how teachers’ implicit beliefs promote and inhibit students’ creativity has important implications for fostering creativity in the classroom. This study investigated whether the effect of teachers’ fixed creative mindset on their self‐efficacy for teaching creativity was mediated by their perceptions of students’ potential and the degree to which this indirect effect varied by level of growth creative mindset. A sample of educators (N = 119) completed an online survey containing questions regarding creative mindsets, perceptions of students’ potential, self‐efficacy for teaching creativity, and a set of relevant covariates. A moderated mediation analysis indicated that the more teachers believed creativity to be innate, the less teachers tended to perceive every student to possess creative potential. Consequently, teachers’ confidence in their ability to teach for creativity was diminished. Results from the corresponding tests of simple indirect effects indicated that this negative indirect effect of a fixed creative mindset was lessened by teachers’ growth creative mindset. Taken together, the findings suggest the likely significant role of teachers’ fixed and growth creative mindsets for fostering creativity in classroom. 相似文献

This paper challenges a standard interpretation according to which Frege’s conception of logic (early and late) is at odds with the contemporary one, because on the latter’s view logic is formal, while on Frege’s view it is not, given that logic’s subject matter is reality’s most general features. I argue that Frege – in Begriffsschrift – retained the idea that logic is formal; Frege sees logic as providing the ‘logical cement’ that ties up together the contentful concepts of specific sciences, not the most general truths. Finally, I discuss how Frege conceives of the application of Begriffsschrift, and of its status as a ‘lingua characteristica’. 相似文献

Training behavioral technicians mainly focuses on teaching accurate implementation of structured behavioral intervention programs. Often behavioral technicians are unable to adequately promote their clients' learning in less structured environments, which can limit opportunities for generalization of the clients' skills to the natural environment. The aim of the present study was to evaluate the effectiveness of using behavioral skills training to coach behavioral technicians on the implementation of naturalistic behavioral interventions. Naturalistic behavioral interventions take advantage of naturally occurring situations to teach new skills and practice mastered skills in natural settings, thus promoting generalization across environments and in the presence of natural contingencies. Five behavioral technicians were trained to implement a novel protocol based on play therapy. Specifically, they were coached to engage in well‐defined positive behaviors during their interactions with clients (e.g., labeled praise). All participants reached mastery criteria, maintained skills at follow‐up, and demonstrated generalization of skills with novel clients. 相似文献

It is well documented that individuals with autism often have significant difficulty with learning to use pronouns appropriately. It does not appear, however, that published studies have systematically investigated teaching procedures for these skills. This study evaluated the effectiveness of a teaching procedure to increase correct pronoun usage as a listener and speaker across four different pronoun pairs (i.e., mine/yours, I/you, me/you, and my/your) using a multiple‐probe design (across pronoun pairs). One participant with autism was taught to discriminate between mine/yours, I/you, me/you, and my/your as both a listener and a speaker. Generalization of the participant's behavior was obtained across novel instructors, places, and stimuli. 相似文献

We introduce a Paraconsistent Informational Logic that formalizes the idea of conjectures which are acceptable as to the quality and the variety of the information that they convey with respect to a given theory T, even if they are classically inconsistent with T. The work constitutes an extension of a previously developed Informational Logic for classical frameworks, where a new notion of logical entropy measure H on formulas and on proofs plays a central role. 相似文献

This is an initial systematic study of the properties of negation from the point of view of abstract deductive systems. A unifying framework of multiple-conclusion consequence relations is adopted so as to allow us to explore symmetry in exposing and matching a great number of positive contextual sub-classical rules involving this logical constant—among others, well-known forms of proof by cases, consequentia mirabilis and reductio ad absurdum. Finer definitions of paraconsistency and the dual paracompleteness can thus be formulated, allowing for pseudo-scotus and ex contradictione to be differentiated and for a comprehensive version of the Principle of Non-Triviality to be presented. A final proposal is made to the effect that—pure positive rules involving negation being often fallible—a characterization of what most negations in the literature have in common should rather involve, in fact, a reduced set of negative rules. 相似文献

In this paper the existence of natural models for a paraconsistent version of naive set theory is discussed. These stand apart from the previous attempts due to the presence of some non-monotonic ingredients in the comprehension scheme they fulfill. Particularly, it is proved here that allowing the equality relation in formulae defining sets, within an extensional universe, compels the use of non-monotonic operators. By reviewing the preceding attempts, we show how our models can naturally be obtained as fixed points of some functor acting on a suitable category (stressing the use of fixed-point arguments in obtaining such alternative semantics). 相似文献

关于阅读中的外显与内隐问题研究--兼谈高师英语阅读教学改革 总被引:4,自引:0,他引:4
目的:从新课程视角,探讨英语阅读中的外显与内隐问题,为阅读教学改革提供理论依据。方法:根据外显学习和内隐学习理论,对分析性阅读和概括性阅读进行分析比较,考察被试在分析性(外显的)和概括性(内隐的)阅读的时候,是如何“投射”出自己获取信息技能的过程的。结果:(1)阅读中存在着内隐现象且具有与外显性阅读相近的阅读成绩和效率;(2)各组被试阅读过程中未见有显著的性别差异;(3)外显阅读组和内隐阅读组均存在着特别显著的年级差异。结论:对于知识的吸收掌握和应用以及阅读能力的培养,外显阅读与内隐阅读各具有特色,互为补充,阅读教学中应充分认识到外显与内隐在阅读理解中的不同效果与作用。 相似文献
