A proof-theoretic analysis and new arithmetical semantics are proposed for some paraconsistent C-systems, which are a relevant sub-class of Logics of Formal Inconsistency (LFIs) introduced by W.A. Carnielli et al. (2002, 2005) [8] and [9]. The sequent versions BC, CI, CIL of the systems bC, Ci, Cil presented in Carnielli et al. (2002, 2005) [8] and [9] are introduced and examined. BC, CI, CIL admit the cut-elimination property and, in general, a weakened sub-formula property. Moreover, a formal notion of constructive paraconsistent system is given, and the constructivity of CI is proven. Further possible developments of proof theory and provability logic of CI-based arithmetical systems are sketched, and a possible weakened Hilbert?s program is discussed. As to the semantical aspects, arithmetical semantics interprets C-system formulas into Provability Logic sentences of classical Arithmetic PA (Artemov and Beklemishev (2004) [2], Japaridze and de Jongh (1998) [19], Gentilini (1999) [15], Smorynski (1991) [22]): thus, it links the notion of truth to the notion of provability inside a classical environment. It makes true infinitely many contradictions B∧¬B and falsifies many arbitrarily complex instances of non-contradiction principle ¬(A∧¬A). Moreover, arithmetical models falsify both classical logic LK and intuitionistic logic LJ, so that a kind of metalogical completeness property of LFI-paraconsistent logic w.r.t. arithmetical semantics is proven. As a work in progress, the possibility to interpret CI-based paraconsistent Arithmetic PACI into Provability Logic of classical Arithmetic PA is discussed, showing the role that PACIarithmetical models could have in establishing new meta-mathematical properties, e.g. in breaking classical equivalences between consistency statements and reflection principles. 相似文献

基于自我决定理论的教师激励风格研究述评 总被引:2,自引:0,他引:2
自我决定理论认为, 教师激励风格是影响学生学习动机的重要外在因素。本文从概念内涵、测量方式、作用机制及影响因素等方面梳理了近十年来教师激励风格的相关研究, 结果发现教师激励风格对学生学习的不同指标都具有重要作用, 但其具体作用机制仍不明确; 而教学动机、教师心理需要的满足等会影响教师激励风格的形成和改变。因此, 在未来的研究中应进一步关注概念结构的澄清、因变量指标的扩充、研究视角的整合和对文化适用性的反思。 相似文献

以青少年学业情绪问卷为基础,结合物理学科特点对问卷项目进行修改,修订中学生物理学业情绪问卷.以314名初二到高二学生为被试进行预测,通过验证性因素分析对问卷项目进行调整,最终问卷包括67个项目.经检验问卷的内部一致性信度、分半信度和效标效度符合测量学的要求.在此基础上,选用728名初二到高三学生为被试.结果发现:(1)总体来看,男生,尤其是来自重点中学的男生,其积极物理学业情绪要高于女生,而女生的消极物理学业情绪要高于男生;(2)重点中学的初中生的积极低唤醒物理学业情绪得分显著高于高中生,且重点中学的初中生的消极低唤醒物理学业情绪得分显著低于高中生,而普通中学则正好相反;(3)在物理学业情绪中,积极高唤醒和积极低唤醒的所有因子与物理学业成就皆呈显著正相关,而消极高唤醒(仅羞愧)和消极低唤醒(厌倦、无助、心烦-疲乏)与物理学业成就呈显著负相关. 相似文献

Based on the standard error of measurement, Holland (1985) suggested the “rule of eight” for determining the meaningfulness of differences between two summary scores on the Self Directed Search. The present study empirically examined the rule's validity for practice. The participants were 2397 (1497 females and 900 males) undergraduate students enrolled in the exploratory major at a large Midwestern university. The results strongly supported the interpretive rule of eight. For those participants who scored a primary-code distinction of eight or more points, the hit rate was 55% with a kappa of .38. This compared to a hit rate of 40% with a kappa of .21 for those participants with less than eight-point distinction between their top two scores. The authors also discuss the practical implications for interpreting SDS results using the “rule of eight.” 相似文献

This article summarizes what is known about the active management of affective organizational commitment (AOC) through a review of 58 studies employing longitudinal research designs. The review yields six broad categories of antecedents that have empirically demonstrated effects on AOC: socialization practices, organizational changes, human resource practices, interpersonal relations, employee–organizational relations, and a residual “other” category. Insights from the review include (a) that perceptions of personal attachment to the organization are among the most substantiated (but tenuous) strategies for enhancing AOC, (b) that theorizing and research efforts have focused almost exclusively on achieving high levels of AOC, and (c) organizations have been reticent to address situations when AOC is low. Implications and recommendations for the theoretical, research and practical advancement of AOC are offered. 相似文献

At an earlier time our work as analysts was easier. We searched for the repressed in order to make constructions that connected the past to the present symptoms. Making these connections conscious, based upon the continuing influence of the Topographic theory, was thought to be the curative factor in psychoanalysis. Freud (1912, 1914) briefly expressed the importance of working in the present but his main focus remained the importance of reconstructing the past. The importance of working in the present started to be fully articulated approximately 30 years ago, and has become a central part of most views on technique. However, it is the contention of this paper that, while there is general agreement on the necessity of working in the here and now, the understanding of what this means or why it is useful runs along parallel lines rather than leading to a central point. Further, it is my impression there is little agreement on the reasons for interpreting the there and then. The idea of a 'workable here and now' is introduced to capture how the here and now might best include the analysand's readiness to synthesize what is offered, while a theory of the necessity for working in the here and now and the there and then is offered. 相似文献

Neuropsychoanalysis focuses on the neural counterparts of psychoanalytically interesting phenomena and has left the difference in the metaphysical presuppositions between neuroscience and psychoanalysis unexamined. The authors analyse the logical possibilities concerning the relation between the brain and the mental unconscious in terms of the serial, parallel, epiphenomenalist and Kantian conceptions, and conclude that none of them provides a satisfactory ground for neuropsychoanalysis. As far as psychoanalytic explanations refer to the mental unconscious, they cannot be verified with the help of neuroscience. Neither is it possible to form a picture of how a neuro-viewpoint might be of help for psychoanalytic theorizing. Neuropsychoanalysis has occasionally been seen as a reductionist affair, but the authors suggest that neuropsychoanalysts themselves lean on the hybrid conception, which combines neuroscientific and psychoanalytic viewpoints. The authors state arguments in favour of the interfield conception of neuropsychoanalysis that takes seriously the metaphysical tensions between neuroscience and psychoanalysis. 相似文献

According to a recently prominent account of moral judgment, genuine moral disapprobation is a product of two convergent vectors of normative influence: a strong negative affect that arises from the mere consideration of a given piece of human conduct and a (socially acquired) belief that this conduct is wrong (Nichols, 2002). The existing evidence in favor of this “norms with feelings” proposal is rather mixed, with no obvious route to an empirical resolution. To help shed further light on the situation, we test a previously unexamined prediction that this account logically yields in a novel dilemmatic context: when individuals are faced with a moral dilemma that pits two or more “affectively-charged” moral norms against each other, the norm underwritten by the strongest feeling ought to determine the content of dilemmatic resolution. Across three studies, we find evidence that directly challenges this prediction, offering support for a Kolhberg-style “rationalist” alternative instead. More specifically, we find that it is not the participants’ degree of norm-congruent emotion (whether situationally or dispositionally assessed) or its correlates, but rather their appraisal of the relative costs associated with various alternative courses of action that appears to be most predictive of how they resolve the experimentally induced moral conflict. We conclude by situating our studies within an overarching typology of moral encounters, which, we believe, can help guide future research as well as shed light on some current controversies within this literature. 相似文献
