In this article, a Bayesian model selection approach is introduced that can select the best of a set of inequality and equality constrained hypotheses for contingency tables. The hypotheses are presented in terms of cell probabilities allowing researchers to test (in)equality constrained hypotheses in a format that is directly related to the data.…

It is shown that there is no ambiguity in Bradford's theory of distribution. Starting with two basic postulates laid down by Bradford, a mathematical expression is derived such that its curve agrees with the experimentally plotted data for periodicals in fields of applied geophysics and lubrication. Five references are listed. (Author/EJS)

Describes a study that tested the status-role hypothesis by examining the citation networks of geographic journals at distinct time points. The need to consider time factors and disciplinary conditions when interpreting clustering representations is discussed. (25 references) (CLB)

This paper provides researchers with a method of determining sample size for a given power level in the preparation of a single group exploratory repeated measure analysis. The rationale for determining sample size which takes into consideration the powers and assumptions of both the adjusted univariate and multivariate repeated measures tests is…

An examination of methodological referencing patterns for actual physics, engineering, and sociology literature for the year 1983, using a Dunn planned comparison approach, indicates that physics differs from both engineering and sociology, while no difference was found between engineering and sociology. References are given in each sample…

Describes a study undertaken to continue work that has been done on the relationship between course completion and telephone tutoring in distance education. Results indicate a statistically significant positive, although modest, relationship does exist; correlation is greater in adult basic education and career technical vocational programs than…

Findings of study of online searchers' self-supported behaviors and attitudes indicate that: there are wide individual differences among online searchers in attitudes and behaviors; searchers from academic institutions differ from counterparts in other library settings; experience appears to be positively related to flexible, trial-and-error…

This study was conducted to determine if viewing a commercially prepared videotape containing written and aural subliminal messages was more effective at producing weight loss than a videotape containing the same content, but without the subliminals. Participants included undergraduate and graduate students from Iowa State University (N=51) who…

Tests hierarchical regression model--library employee's salary is a function of library size, public sector collective bargaining strength, library's ability to pay, cost of living in area, presence of any union and union representing librarians in library--on three salary levels (department head, beginning librarian, clerical worker). (29…

Examines relationship between journal productivity (number of references to particular journal) and journal obsolescence (median age of references to particular journal) for database of references dealing with desalination. Citation age by Bradford zones, continuous measurement of productivity and citation age, and underlying structure of observed…

Two models of library circulation, the Markov model and the mixed Poisson Model, are applied to circulation statistics from the University of Saskatchewan. Goodness-of-fit tests indicate that neither model fits the data; in both cases, the set of noncirculating items is larger than that predicted by the model. (Author/LRW)

Describes a study which compared film and written material with regard to effects produced by order in which conflicting information is presented. Results indicate film is more influential and better recalled than conflicting written information: conflicting paragraphs produce a primacy effect, whereas analogous film segments produce no order…

This nationwide study, conducted to investigate extent to which sex of individual is controlling factor relating to salaries, career progression, and library support, compared the careers of male and female public library directors serving populations of 100,000 or more in continental United States. Questionnaire is appended. (21 references) (EJS)

Overlap (two libraries own same title) and duplication (one library has more than one copy) in children's collections of books and audiovisual materials were measured. It was found that there was less overlap between two school libraries than between a school library and a public library. Six references are cited. (EJS)

This study presents exploratory evidence to prove that student computer usage is correlated with academic performance using course grades as an academic performance measure. No conclusive evidence was found to indicate student performance and computing are related, but a significant relationship between course instructor and computer usage was…
