This response to an earlier article on a combined log-linear/MDS model for mapping journals by citation analysis discusses the underlying assumptions of the Poisson model with respect to characteristics of the citation process. The importance of empirical data analysis is also addressed. (nine references) (LRW)

Proposes methodology for measuring potential demand for individual journals within academic discipline and illustrates this methodology with data from economics journals. The impact of potential demand on journal circulation is investigated by developing a model of journal demand that includes potential demand as an explanatory variable. Five…

The purpose of this work is to help build and bridge between total overviews of the fields of information science and empirical research. This is done by building a model for linking multidisciplinary approaches into a relevant and effective whole, and for deriving testable propositions from this new framework.

A taxonomy for modeling information systems is presented. Epistemology is used as a prescriptive modeling basis and it is shown how the different models can be made scientifically operational by using a special kind of systems analysis. Results of a preliminary experiment based on one of the models are presented. (60 references) (Author/KE)

Discusses the patterns of growth of literature concerning online public access catalogs (OPACs) in the field of library and information science for the years 1970-85. The least squares method and the May procedure, which were used in the study, are explained, and application of the logistic model is described. (16 references) (LRW)

An experiment is described which attempts to define a quantitative methodology for the identification and evaluation of all possibly relevant periodical titles containing toxicological-biological information. A statistical decision model was designed and employed, along with yes/no criteria questions, a training technique and a quality control…

Proposes a model, based on a "maximum ranking method," for more simply estimating the frequency of any same-frequency words and identifying the boundary point between high-frequency and low-frequency words in a text. This model was used successfully with English and Chinese texts, demonstrating that the frequency of words and number of…

Proposes the adoption of a new research paradigm that takes advantage of the digital world and may provide greater insight into how young people seek information. This involves a closer collaboration with youth as partners in constructing research and probing the different criteria of youth for determining the success of a search. (AEF)

Analysis of current models describing citer motivations identified seven most significant motivations for authors: currency scale, negative credit, operational information, persuasiveness, positive credit, reader alert, social consensus. Motivational background for more than 900 citational acts of 26 authors at University of Iowa were gathered and…

Explores similarities between research approaches characterizing different paradigms in information science and different information-processing styles of individual researchers. Proposes a model of the way in which new knowledge is generated, based on these similarities. The model focuses on "research pathologies," and ways in which the…

Results of data analysis on 470 journal titles illustrate complexity of the fuzzy set theory modeling process, which consists of three factors--number of missing issues, citations, circulations--and its limitations in making journal binding decisions. Procedures of research, data collection, and data analysis are discussed. Matrices are included.…

Utilizing 11 years of University of Saskatchewan circulation transactions, it is shown that P. M. Morse's Markov model of book use fits approximately 99 percent of data for whole collection and for three subject areas; contrary to his assumptions, one of the model's parameters is time dependent. Thirteen references are included. (EJS)

Relative effectiveness of indexing using full-text or less than full-text was tested using non-Boolean, chaining type of file structure and searching method. Indexing was done using titles, abstracts, full-text, references, and various combinations; Goffman's indirect method of information retrieval was used to structure and search file.…

Discusses issues related to several models of knowledge transfer and utilization (KTU) from two points of view: that models contain nonspecific treatment characteristics that should be accounted for in their use; and that models provide quantitative and qualitative frameworks that may be ready for quantitative consideration. A nonspecific KTU…

Discussion of relevance provides an overview to this special issue on relevance research. Topics addressed include user-centered criteria that affect relevance judgments; information-seeking behavior; the need for appropriate research methodologies; models for system design and evaluation; and approaches to facilitate further research, including…
