The exponential growth of scholarly publications in recent years has presented a daunting challenge for researchers to keep track of relevant articles within their research field. To address this issue, we examined the capabilities of InfraNodus, an AI-Powered text network analysis platform. InfraNodus promises to provide insights into any…

While explicit conceptual models help to inform research, they are left out of much of the health professions education (HPE) literature. One reason may be the limited understanding about how to develop conceptual models with intention and rigor. Group concept mapping (GCM) is a mixed methods conceptualization approach that has been used to…

Discipline-based education researchers have a natural laboratory--classrooms, programs, colleges, and universities. Studies that administer treatments to multiple sections, in multiple years, or at multiple institutions are particularly compelling for two reasons: first, the sample sizes increase, and second, the implementation of the treatments…

Suppose an education researcher wants to test the impact of a high school drop-out prevention intervention in which at-risk students attend classes to receive intensive summer school instruction. The district will allow the researcher to randomly assign students to the treatment classes or to the control group. Half of the students (the treatment…

Since Topping published his literature review on peer assessment in 1998, the number of studies on this subject has doubled, if not tripled. However, along with this expansion, the diversity of peer assessment applications increased equally fast. Based on recent literature, this contribution focuses specifically on the diversity that has come to…

Using examples of data from the areas of information retrieval and of multivariate data analysis, six hierarchic clustering algorithms (single link, median, centroid, group average, complete link, Wards's) are examined and evaluated by using three proposed coefficients of hierarchic structure. Nine references are cited. (EJS)

Presents system for automatic handling of ordered sets, states based on these sets, and differing points of view regarding Universe of Discourse. Aspects are represented by new logical "overlap" function with examples taken from Ranganathan's horse and carriage parable and several books involving four main concepts (history, geography,…

Of 169 adult and adolescent stutterers studied, 112 reported family history of stuttering. Only 3 of the 112 reported birth or early childhood factors that might precipitate stuttering, as opposed to 21 of those without family history of stuttering. By considering these two conditions as separate factors in behavior, stutterers may be divided into…

A classification of propositions (consisting of a verb and its arguments) is presented with a stipulation of the properties of each type, and clarification is given for how the classfication and the properties function in the interaction between propositions and Japanese aspectual auxiliary verbs. The different types of verbs include: (1) state…

Tests for and identifies populations within a family of electronics industries. Data include 669 United States and 144 Japanese electronics firms. Demonstrates the relevance of a general organizational classification for explaining how different natural selection processes affect different populations. (75 references) (MLF)

The literature of bibliometrics suggests that the results of bibliometric studies can be of practical use in libraries by providing a scientific basis for collection management decisions. Reports on the application of these studies are virtually nonexistent and a number of reasons for this are suggested. (EM)

The role of the coauthor relationship in the structure of informal communications networks within disciplines is explored, and the validity of coauthor graphs used to map these relationships is tested for both small and large databases. (CLB)

This study with 39 secondary students with severe disabilities integrated into regular programs in either home schools or cluster programs found that the proportion of students residing outside the normal school boundaries and the percent of students classified as Severely Multiply Handicapped were both negatively associated with both in-school…

A clustering experiment applied co-citation analysis to a cumulation (1972-1974) of the Social Sciences Citation Index (SSCI) tapes in order to outline a citation structure for the social and behavioral sciences. Co-citation analysis is a new technique that establishes a link between two older documents and a crude metric of the strength of that…

To test validity of cocitation studies as representations of intellectual structure, five-six years of aggregate cocitation data for 41 authors in macroeconomics and 49 authors in genetics of fruit flies were compared with independent judgments of interauthor similarity collected from 14 macroeconomists and 15 geneticists via a card-sorting…
