An argument against multiply instantiable universals is considered in neglected essays by Stanislaw Lesniewski and I.M. Bochenski.
Bochenski further applies Lesniewski’s refutation of universals by maintaining that identity principles for individuals must
be different than property identity principles. Lesniewski’s argument is formalized for purposes of exact criticism, and shown
to involve both a hidden vicious circularity in the form of impredicative definitions and explicit self-defeating consequences.
Syntactical restrictions on Leibnizian indiscernibility of identicals are recommended to forestall Lesniewski’s paradox. 相似文献

A Heyting effect algebra (HEA) is a lattice-ordered effect algebra that is at the same time a Heyting algebra and for which the Heyting center coincides
with the effect-algebra center. Every HEA is both an MV-algebra and a Stone-Heyting algebra and is realized as the unit interval
in its own universal group. We show that a necessary and sufficient condition that an effect algebra is an HEA is that its
universal group has the central comparability and central Rickart properties.

Classical mereology is a formal theory of the part-whole relation, essentially involving a notion of mereological fusion,
or sum. There are various different definitions of fusion in the literature, and various axiomatizations for classical mereology.
Though the equivalence of the definitions of fusion is provable from axiom sets, the definitions are not logically equivalent,
and, hence, are not inter-changeable when laying down the axioms. We examine the relations between the main definitions of
fusion and correct some technical errors in prominent discussions of the axiomatization of mereology. We show the equivalence
of four different ways to axiomatize classical mereology, using three different notions of fusion. We also clarify the connection
between classical mereology and complete Boolean algebra by giving two “neutral” axiom sets which can be supplemented by one
or the other of two simple axioms to yield the full theories; one of these uses a notion of “strong complement” that helps
explicate the connections between the theories. 相似文献

Research examining links between personality and interest have typically focused on links between measures of the five factor model and Holland’s RIASEC types. However, the five factor model of personality can be divided in to a larger set of narrow domain personality scales measuring facets of the ‘big five’ traits. Research in a number of fields indicates that facet scales are effective for clarifying the relationship between personality and other broad constructs, including academic achievement, job performance, stress and coping, and achievement motivation. In the present study links between personality facets and the RIASEC model were examined using property vector fitting. Obtained results are consistent with previous research suggesting that the use of facet-level personality measures can clarify relations between personality and other constructs, and provides new information linking personality facets and interests. The use of facet-level measures of personality expands the range of personality concepts that can be presented to individuals who are exploring career options. 相似文献

归纳推理心理效应的研究 总被引:10,自引:0,他引:10
归纳推理心理效应指的是归纳论断中各种因素对个体做出归纳结论时把握性(力度)大小的影响,根据影响因素的不同,主要可分为类别效应、属性效应和交互效应三种。文章认为,个体通常会采用分割-综合方式判断归纳力度大小,并且在归纳判断中形成的推理序列及由此造成的顺畅感直接影响着归纳力度的估计,作者还提出了对此模型的一种证明 相似文献

We give a detailed account of the Algebraically Closed and Existentially Closed members of the second Lee class B
2 of distributive p-algebras, culminating in an explicit construction of the countable homogeneous universal model of B
2. The axioms of Schmid [7], [8] for the AC and EC members of B
2 are reduced to what we prove to be an irredundant set of axioms. The central tools used in this study are the strong duality of Clark and Davey [3] for B
2 and the method of Clark [2] for constructing AC and EC algebras using a strong duality. Applied to B
2, this method transfers the entire discussion into an equivalent dual category X
2 of Boolean spaces which carry a pair of tightly interacting orderings. The doubly ordered spaces of X
2 prove to be much more readily constructed and analyzed than the corresponding algebras in B

A formal analysis is made of how to project an attribute criterion into the hierarchical classes model for object by attribute data proposed by De Boeck and Rosenberg. The projection is conceptualized as the prediction of the attribute criterion by means of a logical rule defined on the basis of attribute combinations from the model. Eliminative and constructive strategies are proposed to find logical rules with maximal predictive power and minimal formula complexity. Logical analyses of a real data set are reported and compared with a logistic regression to demonstrate the usefulness of the logical strategies, and to show the complementarity of logical and probabilistic approaches.The first suthor is Senior Research Assistant of the National Fund for Scientific Research (Belgium). We would like to thank the Editor, the reviewers, Seymour Rosenberg, and Luc Delbeke for their helpful comments on earlier drafts of this article. 相似文献

Study the role of intellectual property protection in advanced manufacturing SMEs. Is it to protect the growth of advanced manufacturing SMEs, or to inhibit the growth of SMEs in advanced manufacturing? the paper brings the medium variable – technological innovation to explore acting paths of intellectual property protection in enterprises’ value improvement. Through analysis of panel data of 80 SMEs of advanced manufacture collected during the period from 2013 to 2015, Research results show that as for SMEs of advanced manufacture, the inverted-U relationship still exists in the influences brought by intellectual property protection to enterprise values. Meanwhile, U-shaped relations exist between intellectual property protection and technological innovation. Increase of technological innovation investment can promote increase of enterprise values. 相似文献
