User-centered evaluations of information systems often focus on the usability of the system rather its usefulness. This study examined how a using an interactive knowledge-domain visualization (KDV) system affected users' understanding of a domain. Interactive KDVs allow users to create graphical representations of domains that depict important…

Despite reports of academic difficulties in children with attention-deficit/hyperactivity disorder (ADHD), little is known about the relationship between performance on tests of academic achievement and measures of attention. The current study assessed intellectual ability, parent-reported inattention, academic achievement, and attention in 45…

This article addresses the impact of intensive, job-embedded mentor-coaching for 36 teachers and teaching assistants in relation to their language and literacy proficiency and the fidelity of their implementation of the Opening the World of Literacy curriculum. The literacy scores for the majority of teachers in both the treatment and comparison…

A multidimensional unfolding technique that is not prone to degenerate solutions and is based on multidimensional scaling of a complete data matrix is proposed: distance information about the unfolding data and about the distances both among judges and among objects is included in the complete matrix. The latter information is derived from the…

We explore to what extent composite indicators, capable of aggregating multi-dimensional processes into simplified, stylised concepts, are up to the task of underpinning the development of data-based narratives for political advocacy. A recent OECD working paper (Nardo et al., 2005, Handbook on constructing composite indicators: methodology and…

The aim of this study was to describe the hexagonal person-environment fit for the Holland personality types for a Greek sample of 156 university students. The statistical analysis followed both exploratory--such as multidimensional scaling--and confirmatory methods--such as covariance structure models. These methods were employed in an…

Profile Analysis via Multidimensional Scaling (PAMS) is a procedure for extracting latent core profiles in a multitest data set. The PAMS procedure offers several advantages compared with other profile analysis procedures. Most notably, PAMS estimates individual profile weights that reflect the degree to which an individual's observed profile…

Academic dishonesty rates have remained alarmingly high. Various causes and correlates of academic dishonesty have been explored, including such factors as situational and environmental contributors as well as individual differences. Due to the high level of ambiguity inherent in the definition of academic dishonesty, it becomes important to…

A multidimensional model of career success was developed aiming to be more inclusive than existing models. In a first study, 22 managers were asked to tell the story of their careers. At the end of each interview, idiosyncratic career success "construct ladders" were constructed for each interviewee through an interactive process with the…

After a test is developed, most content validation analyses shift from ascertaining domain definition to studying domain representation and relevance because the domain is assumed to be set once a test exists. We present an approach that allows for the examination of alternative domain structures based on extant test items. In our example based on…

This study examined the teaching practices of 227 college instructors of introductory statistics (from the health and behavioral sciences). Using primarily multidimensional scaling (MDS) techniques, a two-dimensional, 10-item teaching practice scale, TISS (Teaching of Introductory Statistics Scale), was developed and validated. The two dimensions…

Professional identity is an ongoing topic of discussion in the youth work literature. This paper looks at one of the key elements of the definition of youth work: the relationships that youth workers establish with young people. It presents research findings which suggest that youth workers have multidimensional relationships with young people…

This article explores both the process and outcomes of a seminar series on the concept of access for people with learning difficulties. The seminar topics chosen to foster dialogue across professional and disciplinary boundaries included access to information, education, employment, the law, health, leisure, community, past histories and future…

Purpose: Much of the recent research on data-driven decision making in US schools has focused on standardized test scores while other forms of data in schools have gone largely unexamined as useful data, such as teacher-assigned grades. Based on the literature, the theory outlined in this paper is that grades, as data historically overlooked in…

Purpose: This study aims to examine the factors of growth-oriented atmosphere in a Finnish polytechnic institution of higher education with categorical exploratory factor analysis, multidimensional scaling and Bayesian unsupervised model-based visualization. Design/methodology/approach: This study was designed to examine employee perceptions of…
