Presents a theory of debate as a comparison of policy systems, a theory which satisfies the unique speech act requirements of discussing policy proposals. Describes the basic model and illustrates it by reference to the interpretation of "should" propositions and the analysis of burdens of proof. (JMF)

There was a significant decrease in the difference between observed and expected probabilities over the first 30 words following a stutter. Also, the two adult Ss initially increased their stuttering rate. Findings supported a combination of the anxiety and feedback models of A. W. Still and C. A. Sherrard. (Author/DLS)

Discusses the importance of a knowledge of basic statistical concepts for a librarian's education, and the problem of implementing such an introductory course. Two class exercises dealing with sampling and probability and the Central Limit Theorem are described, and 11 references are included. (BK)

The influence of frequency of occurrence of a visual stimulus on encoding processes is investigated, to discover what mechanisms allow cognitive processes to modify perceptual processes. Six experiments are described and the results are discussed. (MH)

Suggests that argument be seen as a private cognitive phenomenon, in contrast to the more traditional view of argument as a public message-based document. Differences between the views are noted and the respects in which argument creates and depends on cognitive order are discussed. (JMF)

Two techniques for interpretation of fitted log-linear models in contingency table analysis are discussed. The use of odds ratios as opposed to direct interpretation of the fitted model is argued for. (Author/JKS)

Provides information concerning a procedure for estimating the probability of placement error on a criterion referenced multiple choice test. (TJ)

Presents an alternative derivation of the Fokker-Planck equation for the probability density of a random noise process, starting from the Langevin equation. The derivation makes use of the first two derivatives of the Dirac delta function. (Author/GA)

Emphasizes the importance of precisely defining symbols introduced in deriving relationships between experimental and/or theoretical quantities. An example of a rate constant in unimolecular reaction rate theory is given. (SA)

Discusses a reliability theoretic construct focusing on information produced to satisfy specified purposes or achieve preconceived objectives. When measures of system reliability and sensitivity analyses are performed, the result is a closer congruence between the objectives of the data producer and user requirements. (Author/MBR)

Tries to explain the attraction between unlike charged particles using electromagnetic interaction as described by the quantum field theory. (GA)

Annual records of the one-mile sun can be used to introduce a variety of statistical ideas including the scatter diagram, theoretical vs. observed values, and normal equations. (SD)

This article presents problems to challenge students over and above the standard curriculum problems assigned at a Course I level. Every additional problem in the article can be solved using only the tools provided by Course I. (AIM)

Describes a classroom problem of probability as follows: How many people do you need in a group to ensure that the probability of at least two of them having the same birthday is greater than one-half? Answer: 23. The probability principles needed are simple enough to be accessible to advanced high school students. (PVD)

Describes how three experiments suitable for upper-elementary students can be used to foster classroom discourse in which students begin to explore probability. (KHR)
