The original decision criterion and method of the combined calculus, presented by D. Hilbert and W. Ackermann, and applied by later logicians, are illuminating, but also go seriously awry and lead the universality and preciseness of the combined calculus to be damaged. The main error is that they confuse the two levels of the combined calculus in the course of calculating. This paper aims to resolve the problem through dividing the levels of the combined calculus, introducing a mixed operation mode, and therefore finding a normal-form decision method approximated by that in sentential logic. Finally, this paper provides a more precise proof of Hauber’s theorem by using the normal-form decision method of the combined calculus.  相似文献

In this paper we introduce a paraconsistent reasoning strategy, Chunk and Permeate. In this, information is broken up into chunks, and a limited amount of information is allowed to flow between chunks. We start by giving an abstract characterisation of the strategy. It is then applied to model the reasoning employed in the original infinitesimal calculus. The paper next establishes some results concerning the legitimacy of reasoning of this kind – specifically concerning the preservation of the consistency of each chunk – and concludes with some other possible applications and technical questions.  相似文献

In this article the author describes the Sixteen Personality Factor Questionnaire (16PF) and its junior versions, the High School Personality Questionnaire (HSPQ) and the Children's Personality Questionnaire (CPQ). Development of the tests is described briefly. Reliabilities and validities of the tests are covered, with attention to applications in educational, clinical, and occupational settings.  相似文献

Most agents can acquire information about their environments as they operate. A good plan for such an agent is one that not only achieves the goal, but is also executable, i.e., ensures that the agent has enough information at every step to know what to do next. In this paper, we present a formal account of what it means for an agent to know how to execute a plan and to be able to achieve a goal. Such a theory is a prerequisite for producing specifications of planners for agents that can acquire information at run time. It is also essential to account for cooperation among agents. Our account is more general than previous proposals, correctly handles programs containing loops, and incorporates a solution to the frame problem. It can also be used to prove programs containing sensing actions correct.  相似文献

The early calculus is a popular example of an inconsistent but fruitful scientific theory. This paper is concerned with the formalisation of reasoning processes based on this inconsistent theory. First it is shown how a formal reconstruction in terms of a sub-classical negation leads to triviality. This is followed by the evaluation of the chunk and permeate mechanism (C&P) proposed by Brown and Priest in (Journal of Philosophical Logic, 33(4), 379–388, 2004) to obtain a non-trivial formalisation of the early infinitesimal calculus. Different shortcomings of this application of C&P as an explication of inconsistency tolerant reasoning are pointed out, both conceptual and technical. To remedy these shortcomings, an adaptive logic is proposed that allows for conditional permeations of formulas under the assumption of consistency preservation. First the adaptive logic is defined and explained and thereafter it is demonstrated how this adaptive logic remedies the defects C&P suffered from.  相似文献

I articulate a functional characterisation of the concept of evidence, according to which evidence is that which allows us to make inferences that extend our knowledge. This entails Williamson's equation of knowledge with evidence.  相似文献

We look at two fundamental logical processes, often intertwined in planning and problem solving: inference and update. Inference is an internal process with which we uncover what is implicit in the information we already have. Update, on the other hand, is produced by external communication, usually in the form of announcements and in general in the form of observations, giving us information that might not have been available (even implicitly) before. Both processes have received attention from the logic community, usually separately. In this work, we develop a logical language that allows us to describe them together. We present syntax, semantics and a complete axiom system; we discuss similarities and differences with other approaches and mention how the work can be extended.  相似文献

This study applies social cognitive theory to the study of voter turnout, examining the effects of self‐efficacy on citizens' decisions of whether or not to vote. Consistent with recent arguments in cognitive psychology ( Fenton‐O'Creevy, Nicholson, Soane, & Willman, 2003, 2005 ), I argue that excessive perceptions of self‐efficacy lead some citizens to overestimate their vote's impact in close elections and to vote as a consequence of these perceptions. This illusion of control is further engendered by the features of skill‐based activities such as choice, personal involvement, stimulus familiarity, and exertion of effort ( Langer, 1975 ) that are inherent in the act of voting. Employing both cross‐sectional and panel data, I find that individuals with high levels of self‐efficacy are more likely to be moved to vote by perceptions that an election will be close than are citizens with low levels of self‐efficacy.  相似文献

近代共识的中医属性是以阴阳五行、辨证论治等为特征的中医理论体系,以治疗慢性病和调理平衡为特点.但对医史的重温,却见中医曾经遏制烈性病的传播、曾经有过启迪性的医学发现,更有近年因发现抗疟药青蒿素使中医得到医学界褒奖.中医属性与这些史实的矛盾提示中医遗产不限于其理论体系,需重新审视中医并调整中医的挖掘和发展战略.  相似文献

Leadership in brief training groups requires a high level of skill, energy, and professionalism. The group needs to be led in a purposeful, constructive manner. A metaphor for beneficial leadership is suggested through the image of a mountain guide who sustains and helps members of the group in their exploration of the psychological terrain that is themselves. The leader has five main tasks: (1) to contain the anxieties of the group, (2) quickly establish a therapeutic atmosphere in the group, (3) guide the group toward issues that can be addressed in the time available, (4) guard against damaging self-disclosure and loss of self-esteem, and (5) help the group end well. Clinical vignettes illustrate the realization of these practice points.  相似文献

采用学习迁移任务范式,使用基于单一特征的类别判断技术,比较了三水平特征的家族性似性类别结构下,分类学习和推理学习的学习效率、学习过程与策略和学习结果.结果表明:在学习效率上,分类学习在达标率上优于推理学习,而在速度上,两者差异不显著.在学习的过程与策略上 ,推理学习相对较快地从单维度策略转向使用规则加例外策略,而分类学习表现出一定程度的潜伏学习, 并在高水平的信息整合策略使用上,赶上了推理学习.在学习的结果上,分类学习比推理学习更好掌握了类别的原型.  相似文献

中国传统经济伦理及其现代变革论纲   总被引:3,自引:0,他引:3  
要建设社会主义市场经济体系,必须对传统经济伦理进行根本的变革:(1)变革“重公轻私”的产权伦理;(2)变革“不患贫而患不均”的分配伦理;(3)变革通行于熟人社会的“诚信”道德;(4)变革“家庭主义”。但由于存在着制度变迁的路径依赖,因而“传统经济伦理”的现代变革将是一个相当困难的过程。  相似文献
