The implicational fragment of the relevance logic “ticket entailment” is closely related to the so-called hereditary right
maximal terms. I prove that the terms that need to be considered as inhabitants of the types which are theorems of T→ are in normal form and built in all but one case from
and
only. As a tool in the proof ordered term rewriting systems are introduced. Based on the main theorem I define FIT→ – a Fitch-style calculus (related to FT→) for the implicational fragment of ticket entailment. 相似文献

In three-mode Principal Components Analysis, theP ×Q ×R core matrixG can be transformed to simple structure before it is interpreted. It is well-known that, whenP=QR,G can be transformed to the identity matrix, which implies that all elements become equal to values specified a priori. In
the present paper it is shown that, whenP=QR − 1,G can be transformed to have nearly all elements equal to values spectified a priori. A cllsed-form solution for this transformation
is offered. Theoretical and practical implications of this simple structure transformation ofG are discussed.

In this paper we show that the quasivariety generated by an infinite simple MV-algebra only depends on the rationals which it contains. We extend this property to arbitrary families of simple MV-algebras. 相似文献

We introduce two simple empirical approximate Bayes estimators (EABEs)—
and
—for estimating domain scores under binomial and hypergeometric distributions, respectively. Both EABEs (derived from corresponding marginal distributions of observed test scorex without relying on knowledge of prior domain score distributions) have been proven to hold -asymptotic optimality in Robbins' sense of convergence in mean. We found that, where
and
are the monotonized versions of
and
under Van Houwelingen's monotonization method, respectively, the convergence rate of the overall expected loss of Bayes risk in either
or
depends on test length, sample size, and ratio of test length to size of domain items. In terms of conditional Bayes risk,
and
outperform their maximum likelihood counterparts over the middle range of domain scales. In terms of mean-squared error, we also found that: (a) given a unimodal prior distribution of domain scores,
performs better than both
and a linear EBE of the beta-binomial model when domain item size is small or when test items reflect a high degree of heterogeneity; (b)
performs as well as
when prior distribution is bimodal and test items are homogeneous; and (c) the linear EBE is extremely robust when a large pool of homogeneous items plus a unimodal prior distribution exists.The authors are indebted to both anonymous reviewers, especially Reviewer 2, and the Editor for their invaluable comments and suggestions. Thanks are also due to Yuan-Chin Chang and Chin-Fu Hsiao for their help with our simulation and programming work. 相似文献

Two experiments examined the effects of session duration on responding during simple variable-interval schedules. In Experiment 1, rats were exposed to a series of simple variable-interval schedules differing in both session duration (10 min or 30 min) and scheduled reinforcement rate (7.5 s, 15 s, 30 s, and 480 s). The functions relating response rate to reinforcement rate were predominantly monotonic for the short (10-min) sessions but were predominantly bitonic for the long (30-min) sessions, when data from the entire session were considered. Examination of responding within sessions suggested that differences in the whole-session data were produced by a combination of prospective processes (i.e., processes based on events scheduled to occur later in the session) and retrospective processes (i.e., processes based on events that had already occurred in the session). In Experiment 2, rats were exposed to a modified discrimination procedure in which pellet flavor (standard or banana) predicted session duration (10 min or 30 min). All rats came to respond faster during the short (10-min) sessions than during the first 10 min of the long sessions. As in Experiment 1, the results seemed to reflect the simultaneous operation of both prospective and retrospective processes. The results shed light on the recent controversy over the form of the variable-interval response function by identifying one variable (session duration) and two types of processes (prospective and retrospective) that influence responding on these schedules. 相似文献

This paper details Von Lüttichau’s relationship with Carl Jung and Bill Wilson, co-founder of Alcoholics Anonymous (AA), and her role as intermediary in the relationship between the two men. Her contribution within this mediator role has not been previously recognized but is an important factor in explaining how Jung became introduced to the AA 12-step format and validated the effectiveness of group work. After the Second World War, Von Lüttichau travelled between America and Switzerland and introduced the writings and ideas of Wilson and Jung to each other and acted as an intermediary between both titans. Jung gave Von Lüttichau extraordinarily detailed instructions on how the 12-step programme of AA could be applied to ‘general neurotics’. Von Lüttichau’s private papers provide a bridge between Jung and Wilson’s correspondence and help to piece together gaps in both Jungian and AA history. 相似文献

AbstractDirection dependence analysis (DDA) makes use of higher than second moment information of variables (x and y) to detect potential confounding and to probe the causal direction of linear variable relations (i.e., whether x?→?y or y?→?x better approximates the underlying causal mechanism). The “true” predictor is assumed to be a continuous nonnormal exogenous variable. Existing methods compatible with DDA, however, are of limited use when the relation of a focal predictor and an outcome is affected by a moderator. This study presents a conditional direction dependence analysis (CDDA) framework which enables researchers to evaluate the causal direction of conditional regression effects. Monte–Carlo simulations were used to evaluate two different moderation scenarios: Study 1 evaluates the performance of CDDA tests when a moderator affects the strength of the causal effect x?→?y. Study 2 evaluates cases in which the causal direction itself (x?→?y vs y?→?x) depends on moderator values. Study 3 evaluates the robustness of DDA tests in the presence of functional model misspecifications. Results suggest that significance tests compatible with CDDA are suitable in both moderation scenarios, i.e., CDDA allows one to discern regions of a moderator in which the causal direction is uniquely identifiable. An empirical example is provided to illustrate the approach. 相似文献
