Discussion of journals and the nature of their interrelationships focuses on a loglinear model of citation frequency that allows an examination of the influence between journals of related disciplines. Multidimensional scaling (MDS) is described, and an example using the Social Sciences Citation Index (SSCI) and journals relating to marketing is…

Describes content-validity theory and illustrates new and traditional approaches for conducting content-validity studies. Newer approaches are based on multidimensional scaling analysis of item-similarity ratings, while traditional approaches are based on ratings of item-objective congruence and relevance. (Author/SLD)

Evaluates burden as experienced by a group of American Indian primary family caregivers. Analysis of items composing the Caregiver Burden scale indicate that caregiver burden is multidimensional and consists of several types of burden. Finds that caregiver burden is composed of four dimensions: role conflict, negative feelings, lack of caregiver…

Examines the structure of medical informatics and the relationship between biomedicine and information science and information technology. Uses co-occurrence analysis of subject headings assigned to items indexed for MEDLINE as well as multidimensional scaling to show seven to eight broad multidisciplinary subject clusters. (Contains 28…

Examines the factor structure of the Miville-Guzman Universality-Diversity Scale (M-GUDS) and presents a short form of the scale (M-GUDS-S). Findings suggest that the M-GUDS-S measures Universal-Diverse Orientation as a multidimensional construct with three distinct domains: behavioral, emotional, and cognitive. (Contains 21 references and 3…

Despite several decades of activity, alcohol expectancy research has yet to merge measurement approaches with developing memory theory. This article offers an expectancy assessment approach built on a conceptualization of expectancy as an information processing network. The authors began with multidimensional scaling models of expectancy space,…

Attachment Q-Sort (AQS) is a tool for quantifying observations about toddler/caregiver relationships. Previous studies have applied factor analysis to the full 90 AQS item set to explore the structure underlying them. Here we explore that structure by applying multidimensional scaling (MDS) to judgements of inter-item similarity. AQS items are…

The emergence of theory-driven evaluation has drawn attention to the need for practical ways for evaluators to construct program theory to achieve the benefits of the approach. This article illustrates the use of concept mapping as a technique to explicate underlying program theory in the context of family support programs. In this example, 29…

With the individualisation and multiculturalisation of the world of education and training and the world of work, a new need has arisen to develop a more value-based and existentially oriented approach to guidance theory and vocational training courses. The pluralisation of ways of life and the late-modern confrontation with the authorities have…

Although there are many methods available for dimensionality assessment for items with monotone item response functions, there are few methods available for unfolding item response theory models. In this study, a modification of Yen's Q3 statistic is proposed for the case of these nonmonotone item response models. Through a simulation study, the…

Purpose: Investigate training-related changes in acoustic-phonetic representation of consonants produced by a text-to-speech (TTS) computer speech synthesizer. Method: Forty-eight adult listeners were trained to better recognize words produced by a TTS system. Nine additional untrained participants served as controls. Before and after training,…

This study examined the impact of rater agreement on decisions concerning the alignment between the "Golden State Examination in High School Mathematics" (California Department of Education, 2001a) and the University of California (UC) "Statement on Competencies in Mathematics Expected of Entering College Students" (Academic…

This study was designed to determine a word problem difficulty classification in children with arithmetic learning disabilities (ALD; n = 104) in comparison with typically achieving students (n = 44). We tested variables such as (a) semantic structure (Change, Combine, Compare, and Equalize), (b) operation (subtraction and addition), and (c)…

In the SIMPLE model (Scale Invariant Memory and Perceptual Learning), performance on memory tasks is determined by the locations of items in multidimensional space, and better performance is associated with having fewer close neighbors. Unlike most previous simulations with SIMPLE, the ones reported here used measured, rather than assumed,…

The goal of this study is to investigate how features of a rating scale developed for English-speaking populations interact with Spanish-speaking respondents' response styles and functional categories of judgment. A sample of 400 Spanish-speaking students took a translated scale and a scaling task developed to measure response sets and functional…
