Profile data abound in a broad range of research settings. Often it is of considerable theoretical importance to address specific structural questions with regard to the major pattern as included in such data. A key challenge in this regard pertains to identifying which type of interaction (double ordinal, mixed ordinal/disordinal, double…

We examine a generalization of the one-dimensional Ising model involving interactions among neighbourhoods of "k" adjacent spins. The model is solved by exploiting a connection to an interesting computational problem that we call ""k"-SAT on a ring", and is shown to be equivalent to the nearest-neighbour Ising model in the absence of an external…

The study examines the agreement among raters on children's problematic behaviors. A multitrait-multimethod (MTMM) matrix was applied to a normative sample of elementary school-aged children (N = 841). The participants were rated by their physical educators, using the Motor Behavior Checklist for children (MBC; Efstratopoulou, Janssen, &…

The Knowledge Society Network (KSN) "takes advantage of new knowledge media to maximize and democratize society's knowledge-creating capacity" (www.ikit.org/KSN). This article synthesizes the principles and designs of this network which were initiated over 15 years ago, and presents an exploratory study of interactions in the KSN over…

This paper presents a revised and updated version of a FORTRAN program which computes all indices used in the Flanders' Interaction Matrix. The new program has added another form of data input which simplifies data entry. The new version also has the capability of interactive terminal use. (Author)

The Kaiser Measures of Sampling Adequacy (MSA) were derived for a typical six-concept Semantic Differential. The overall indices indicated that both concept and total correlation matrices would lead to comparable decisions regarding the psychometric quality of the sample data sets. The individual MSA's, however, revealed considerable variability…

A purpose of youth organizations is to develop leadership skills among members through organizational structure and organization sponsored activities. But do they develop those skills? This national, multi-stage study examined the role of youth and the context of their activities in developing leadership in rural FFA chapters. FFA members had a…

Simultaneous test procedures (STPS for short) in the context of the unrestricted full rank general linear multivariate model for population cell means are introduced and utilized to analyze interactions in factorial designs. By appropriate choice of an implying hypothesis, it is shown how to test overall main effects, interactions, simple main,…

The Social Relations model of D. A. Kenny estimates variances and covariances from a round-robin of two-person interactions. This paper presents a matrix formulation of the Social Relations model, using the formulation to derive exact and estimated standard errors for round-robin estimates of Social Relations parameters.

Attempts to determine the degree to which communication may be viewed as structured sequences of behavior. Includes an analysis of discussion groups, teacher classroom behavior, speech therapy sessions and police-civilian telephone calls. See CS 703 503 for availability information. (MH)

The Children's Interaction Matrix, Intermediate and Primary Forms, are designed to identify the preferred work and content styles of children in group situations. These factors aid the researcher, teacher, and counselor in understanding the individual's preferred mode of behavior in groups as well as indicating the students' reaction to group…

Examines relationships between the two major components of computer simulations, the computer and participants; highlights major differences between computer-assisted, computer-based, and computer-controlled simulations; and describes three computer-assisted simulations to illustrate the interdependence of the major components. (MBR)

Describes how the structure of hypermedia systems can be represented by a simple matrix which is the basis for applying standard techniques of network analysis, and demonstrates the potential influence of these techniques on learning processes or outcomes. Also discusses theoretical and practical implications for future hypermedia research. (AEF)

The premise of this book is that successful management depends primarily on the fundamental structures and procedures that a college or university has in place. It is noted that flaws in these structures and procedures will doom efforts to achieve institutional goals. This book, which offers guidance to higher education administrators in…

The 7th International Conference on Education Data Mining held on July 4th-7th, 2014, at the Institute of Education, London, UK is the leading international forum for high-quality research that mines large data sets in order to answer educational research questions that shed light on the learning process. These data sets may come from the traces…
