The mathematical concept of pragmatic truth, first introduced in Mikenberg, da Costa and Chuaqui (1986), has received in the last few years several applications in logic and the philosophy of science. In this paper, we study the logic of pragmatic truth, and show that there are important connections between this logic, modal logic and, in particular, Jaskowski's discussive logic. In order to do so, two systems are put forward so that the notions of pragmatic validity and pragmatic truth can be accommodated. One of the main results of this paper is that the logic of pragmatic truth is paraconsistent. The philosophical import of this result, which justifies the application of pragmatic truth to inconsistent settings, is also discussed. 相似文献

A relationship is given between the joint common factor structure of two sets of variables, and the factor structure of the partial covariance matrix of one of the sets with the other partialled out. 相似文献

Several algorithms for covariance structure analysis are considered in addition to the Fletcher-Powell algorithm. These include the Gauss-Newton, Newton-Raphson, Fisher Scoring, and Fletcher-Reeves algorithms. Two methods of estimation are considered, maximum likelihood and weighted least squares. It is shown that the Gauss-Newton algorithm which in standard form produces weighted least squares estimates can, in iteratively reweighted form, produce maximum likelihood estimates as well. Previously unavailable standard error estimates to be used in conjunction with the Fletcher-Reeves algorithm are derived. Finally all the algorithms are applied to a number of maximum likelihood and weighted least squares factor analysis problems to compare the estimates and the standard errors produced. The algorithms appear to give satisfactory estimates but there are serious discrepancies in the standard errors. Because it is robust to poor starting values, converges rapidly and conveniently produces consistent standard errors for both maximum likelihood and weighted least squares problems, the Gauss-Newton algorithm represents an attractive alternative for at least some covariance structure analyses.Work by the first author has been supported in part by Grant No. Da01070 from the U.

A new algorithm is used to test and describe the set of all possible solutions for any linear model of an empirical ordering derived from techniques such as additive conjoint measurement, unfolding theory, general Fechnerian scaling and ordinal multiple regression. The algorithm is computationally faster and numerically superior to previous algorithms.This research was supported in part by NIGMS grant GM-01231 to the University of Michigan.

春秋邦交的特点,学者多有论及,但均不完善。本文从春秋邦交的主体一一各诸侯国的国家形态人手,对春秋时期各诸侯国在邦交中的地位和独立主权意识进行了探索,认为春秋列国在国家形态方面正处于一个由残缺向完整转变的过渡时期。因此,春秋邦交势必受其影响而具有自己独有的时代特点。 相似文献

A common design in social psychology involves the use of two independent variables, an experimental manipulation and a measured individual difference, and the interest is in the interaction between them. In such designs, there are often obvious covariate(s), correlated with the measured independent variable, which the researcher wishes to control. Typically this is done by including the covariate in the analytic model. We show that in most cases this is an inadequate model. In general, the interaction between the two independent variables will be estimated without bias only when the interaction between the covariate and the manipulated independent variable is included in the analysis. We present simulations showing the factors affecting the magnitude of the bias and provide a survey of recent social psychological literature illustrating the frequency of the problem. Finally, we discuss cases where both independent variables are manipulated and the covariate is a potential mediator. 相似文献

I survey in this article the practical uses of computers in philosophy: except for logic, computers have not yet noticeably improved the quality of philosophizing, research, or pedagogy. They have made work easier. My main interest, however, is in the "substantive" impact that computers may have on philosophical problems, especially in metaphysics. I argue that logic, the notion of decidability, and the theory of computation all predated and did not require modern digital computers. In the philosophy of mind, there has been a persistent conflation of computationalism and physicalism. The two theses can and should be separated. Finally, I suggest that we see glimpses of a new metaphysics based on information and information transformations that goes far beyond the well-trodden mind-brain debates. 相似文献

It is a commonplace that the extensions of most, perhaps all, vague predicates vary with such features as comparison class
and paradigm and contrasting cases. My view proposes another, more pervasive contextual parameter. Vague predicates exhibit
what I call open texture: in some circumstances, competent speakers can go either way in the borderline region. The shifting
extension and anti-extensions of vague predicates are tracked by what David Lewis calls the “conversational score”, and are
regulated by what Kit Fine calls penumbral connections, including a principle of tolerance. As I see it, vague predicates
are response-dependent, or, better, judgement-dependent, at least in their borderline regions. This raises questions concerning
how one reasons with such predicates.
In this paper, I present a model theory for vague predicates, so construed. It is based on an overall supervaluationist-style
framework, and it invokes analogues of Kripke structures for intuitionistic logic. I argue that the system captures, or at
least nicely models, how one ought to reason with the shifting extensions (and anti-extensions) of vague predicates, as borderline
cases are called and retracted in the course of a conversation. The model theory is illustrated with a forced march sorites
series, and also with a thought experiment in which vague predicates interact with so-called future contingents. I show how
to define various connectives and quantifiers in the language of the system, and how to express various penumbral connections
and the principle of tolerance. The project fits into one of the topics of this special issue. In the course of reasoning,
even with the external context held fixed, it is uncertain what the future extension of the vague predicates will be. Yet
we still manage to reason with them. The system is based on that developed, more fully, in my Vagueness in Context, Oxford, Oxford University Press, 2006, but some criticisms and replies to critics are incorporated. 相似文献
