Reviews historical thinking about visual literacy; addresses the issue of setting visual literacy's parameters; provides a rationale linking individuals in an otherwise multidisciplinary movement; proposes a redefinition of visual literacy; and postulates proposals designed to foster further development and understanding of the theoretical…

Four empirical laws of bibliometrics--anomalous number, Lotka's, Zipf's, and Bradford's--together with Laplace's "law of succession" and de Solla Price's cumulative advantage distribution are shown to be almost identical. A simple model shows that the frequency forms conform with inverse square law over appropriate interval. (Fifteen…

This essay distinguishes several different kinds of measures of information from each other, noting that differences between them show that our pretheoretical concept of information is multiply ambiguous. Incremental information, conditional information, transmitted information, expected information, and deductive information are discussed. Ten…

Examines the meaning of practicing sociology, claiming to "commit a social science" still makes sense. Accepts Max Weber's arguments that sociology clarifies human affairs and is oriented to certain virtues. Suggests, however, that sociology is a passion as well as a profession, something Weber recognized but did not elaborate. (NL)

A theory of neurolinguistic function is proposed to explain fluency and the production of stuttered speech disruptions. Stuttering results when the speaker is under time pressure and is unaware of the cause of dyssynchrony between the linguistic and paralinguistic components of speech which are processed by different neural systems but converge on…

A novel theory about Earth's ancient history is presented. It is proposed that North America and Antarctica once lay side by side for perhaps as long as a billion years. The importance of these continental connections to geology and other disciplines is discussed. (KR)

Correlations between centralization and effectiveness were obtained from 26 independent samples in the organization science literature. Hypotheses were developed and statistically tested. The hypotheses that were supported are reflected in a final theory of the centralization-effectiveness relationship. (75 references) (MLF)

Three studies are reported that address the often-described impoverished creativity in children with either autism or Asperger syndrome. Findings indicated both groups were more likely to generate reality-based than imaginative ideas. Results support both the executive dysfunction and the imagination-deficit hypotheses for the observed deficiency.…

This study compared 20 prelingually profoundly deaf adolescents (age 11-16 years) and 20 matched, hearing adolescents on a picture-sequencing task and a social judgment test. Results did not support the hypothesis that deaf adolescents possess significantly poorer knowledge about social reasoning than hearing peers but it did support the…

The concept of habitus lies at the heart of Bourdieu's theoretical framework. It is a complex concept that takes many shapes and forms in Bourdieu's own writing, even more so in the wider sociological work of other academics. In the first part of this paper I develop an understanding of habitus, based on Bourdieu's many writings on the concept,…

There has been in the field of psychology a long and well-documented discontent with an apparent disorganization in its literature, most often interpreted as reflecting the absence of a unifying theory. This article examines some alternative ways in which some of the disorganization is being actively created by forms of argumentation used in…

The absence of a central database and use of specialized language hinder nonexperts in becoming familiar with the science teaching and learning literature and using it to inform their work. The challenge of locating articles related to a specific question or problem, coupled with the difficulty of comprehending findings based on a variety of…

This monograph represents 5 years of collaborative discussions among individuals interested in improving the teaching and learning of mathematics beginning in 1985 with the planning of a conference and culminating in the production of this collection of 13 papers to be presented at the conference. Chapters include: (1) an introduction…

In reviewing Herbert J. Klausmeier's academic career, this paper discusses four major areas of his contributions: (1) cognitive learning and development (CLD); (2) individual differences and related educational provisions; (3) educational research as a field of scientific inquiry; and (4) teacher education. CLD, Klausmeier' major contribution, was…

For many years personalization of achievement testing has been impossible in all but the simplest forms. Recently, item response theory (IRT), or latent trait theory, has emerged as a valuable tool which brings far greater flexibility to the process than had previously been possible. The single parameter Rasch Model, a mathematical model developed…
