The purpose of this study was to determine the various ways in which audience members recall and quantify messages coming through the different media. The data presented here were collected during the course of a panel study into the social context of mass media use. The measurement and analytic techniques are exploratory. The respondents were…

"Pure" academic research rules on data collection do not apply directly to operations research (OR). OR data collection should be viewed in terms of objective, cost, and effectiveness. For the model formulation objective, proper data strategies emphasize multiple views of the operating system to identify the "relatednesses" to be depicted. For the…

A clearer understanding of the capacity of research and researchers in the mass communication field is needed. In the past, when statistical researchers have found they cannot meet criteria, they have devised a new set of test characteristics. For example, when validity cannot be measured, researchers measure reliability, despite the fact that…

The purposes of this paper were to briefly define content analysis, to report the findings of a survey of dissertations using content analysis methodology in the field of youth media, to place these studies into a typological pattern, and to suggest needed content analysis research in media for youth. Eighty-nine studies selected from a total of…

The problem of the comparability of change scores is investigated. Change quotients and residual change scores are evaluated as alternative approaches and methods for estimating the true change and true score residual, the reliability of change scores and residuals, and procedures for constructing confidence intervals for residuals are explored.…

This paper examines interaction in a school class through the factor-analytical P-technique, considers the behavior of the factor scores in combination with certain other variables included in the interaction matrix, explores the formation of homogeneous groups of lessons in a grouping analysis based on the factor scores, and compares this latter…

This study examines quantification of the instructional process through the use of Markov chaining, and by considering the transition probabilities within a framework provided by the taxonomy used, attempts to obtain information about behavior sequences common to all lessons. (Author/DLG)

Examines the development of statistical power as a methodological concern in the communication discipline and the effects of this concern on recent empirical research conducted by communication scientists. (MH)

Discussion of history as a major research methodology in library and information science highlights the current status and nature of library history; rhetoric and history; historical significance of local history and larger perspectives; primary and secondary information sources; library biography; and publishing library history. Thirty-four…

The hypothesis was tested that forgetting could be found on one trial in the absence of interference if the conditions or response-produced feedback were sufficiently reduced. The task was the learning and recall of a linear movement. (Author)

The "history of education" should no longer be considered an independent field for research and teaching. Many important questions in the history of ideas have been and continue to be numberically based, and require quantitative analysis to be answered. Revisionism in history has often involved the use of a quantitative methodology. (Author/JM)

Presents a concentric research design model based on need for research which transcends individuals' historic or experiential bias concerning choice of study design, tools, and data reduction strategies. Describes the following "rings": theory/knowledge orientation; theory versus applied research; quantitative versus qualitative research…

The effectiveness of manual and computer-assisted legal research (CALR) methods are examined and compared, and the limitations of each are noted. The current state of law students' research skills is then discussed, and the Brooklyn Law School (New York) response to the problem, integrating the methods, is described. (MSE)

Because assessment instruments of the future may well be composed of a combination of types of questions, a way to combine those scores effectively is discussed. Two new graphic tools are presented that show that it may not be practical to equalize the reliability of different components. (SLD)

Raises questions about the validity and reliability of doing research online via the proliferation of academic databases. Finds different versions of the Lexis-Nexis database have differing search capabilities. Argues that dependence on database research findings means dependence on decisions made by a few people who design search engines and…
