Practical Arguments for Theoretical Theses

Pascals wager is expounded as a paradigm case of a practical,decision-theoretical argument for acting as if a proposition is true when wehave no theoretical reasons to accept or reject it (1.1.–1.2.). Thoughthe paradigm is fallacious in various respects there are valid and adequatearguments for acting as if certain propositions are true: that theoreticalentities exist, that there are material perceptual objects, that the worldis uniform across time (1.3). After this analysis of examples the authorsgeneral approach for developing criteria for the validity and adequacy oftypes of argument (2.1.) is applied: Having discussed some problems(2.2.–2.3.), a general epistemic principle for such pascal argumentsis developed, which characterizes their premisses and, if introduced as anadditional premiss, can make them deductively valid (2.4).     

Family Therapy with English Caribbean Immigrant Families in the United States: Issues of Emigration, Immigration, Culture, and Race

Many English Caribbean families in the United States are referred for therapy because of difficulties related to their adaptation to a new country/culture. This paper focuses on the intra-familial, and the family-larger system transitional/adjustment difficulties experienced by these families and presents issues specific to therapy with them. Effective therapy with English Caribbean families and their subsystems requires that therapists communicate to these families an understanding of their concerns, be knowledgeable about heterogeneity in cultural values and traditions, and create a therapeutic atmosphere in which families can feel valued and respected. Recommendations for therapists are presented and discussed.     

Lambda Calculus and Intuitionistic Linear Logic

The introduction of Linear Logic extends the Curry-Howard Isomorphism to intensional aspects of the typed functional programming. In particular, every formula of Linear Logic tells whether the term it is a type for, can be either erased/duplicated or not, during a computation. So, Linear Logic can be seen as a model of a computational environment with an explicit control about the management of resources.This paper introduces a typed functional language ! and a categorical model for it.The terms of ! encode a version of natural deduction for Intuitionistic Linear Logic such that linear and non linear assumptions are managed multiplicatively and additively, respectively. Correspondingly, the terms of ! are built out of two disjoint sets of variables. Moreover, the -abstractions of ! bind variables and patterns. The use of two different kinds of variables and the patterns allow a very compact definition of the one-step operational semantics of !, unlike all other extensions of Curry-Howard Isomorphism to Intuitionistic Linear Logic. The language ! is Church-Rosser and enjoys both Strong Normalizability and Subject Reduction.The categorical model induces operational equivalences like, for example, a set of extensional equivalences.The paper presents also an untyped version of ! and a type assignment for it, using formulas of Linear Logic as types. The type assignment inherits from ! all the good computational properties and enjoys also the Principal-Type Property.     

Behavioral and Emotional Problems in Young Preschoolers: Cross-Cultural Testing of the Validity of the Child Behavior Checklist/2-3

The cross-cultural validity of the Child Behavior Checklist for Ages 2-3 (CBCL/2-3) was tested in three Dutch samples of children referred to mental health services, from the general population, and from a twin study. Six scales were derived from factor analyses and labeled Oppositional, Aggressive, and Overactive, which constituted a broadband Externalizing grouping; Withdrawn/Depressed and Anxious, which constituted a broadband Internalizing grouping; and Sleep Problems. Internal consistencies of the scales, their test-retest reliabilities, interparent agreement, discriminative power, predictive relations with problem ratings 2 years later, and relations to other instruments designed to measure general development and behavior problems were adequate, and highly comparable to psychometric properties in American samples. It was concluded that across languages and cultures behavioral/emotional problems of young preschoolers may be adequately assessed with the CBCL/2-3.     

Further evaluation of self and peer judgements of speech with delayed auditory feedback

Fifteen undergraduate students recorded a standard reading passage under simultaneous auditory feedback (SAF) and delayed auditory feedback (DAF, 210 ms). These pairs were rated for articulation and fluency differences, reading rate differences, pitch differences, loudness differences, and overall differences in quality of speech by the fifteen speakers and by ten peer judges. Results suggest that naive speakers under DAF form a self-impression of the effects of DAF upon their speech that is not different from the qualitative ratings of independent peer judges. The hypothesis that there was no overall difference between self and peer ratings was not rejected. Implications for the use of DAF as a research or treatment modality, or as both, are discussed.     

Recovery of single word comprehension: CT-scan correlates

9tory comprehension for single words, as measured by the BDAE Word Discrimination subtest, was studied longitudinally in a group of 37 aphasic patients. The majority of the patients had impaired performance at 1 month postonset, but recovery by Month 6 postonset was quite striking. Damage to Wernicke's area did not preclude recovery of single word comprehension to within the normal range. Only patients with very extensive left hemisphere lesions had incomplete recovery of single word comprehension.     

Comparing one-step m-estimators of location corresponding to two independent groups

Experience with real data indicates that psychometric measures often have heavy-tailed distributions. This is known to be a serious problem when comparing the means of two independent groups because heavy-tailed distributions can have a serious effect on power. Another problem that is common in some areas is outliers. This paper suggests an approach to these problems based on the one-step M-estimator of location. Simulations indicate that the new procedure provides very good control over the probability of a Type I error even when distributions are skewed, have different shapes, and the variances are unequal. Moreover, the new procedure has considerably more power than Welch's method when distributions have heavy tails, and it compares well to Yuen's method for comparing trimmed means. Wilcox's median procedure has about the same power as the proposed procedure, but Wilcox's method is based on a statistic that has a finite sample breakdown point of only 1/n, wheren is the sample size. Comments on other methods for comparing groups are also included.
