Tested prefrontal and hippocampal functions in school-aged individuals with Down syndrome (DS) compared functions with those of typically developing children individually matched on mental age. Found that hippocampal and prefrontal composite scores contributed unique variance to the prediction of mental age and adaptive behavior. Noted a…

Examines reasons for cataloging backlogs in libraries and describes a preliminary theory of backlog dynamics. Formulas for predicting backlogs are discussed, backlog models are explained, the use of computer simulation software to form models is described, and further research is suggested. (five references) (LRW)

Examines difficulties with citation analysis as it is used to study citation frequency, usually for the evaluation of scientists, publications, or institutions. Topics addressed include selection of a control set of papers, comparisons of different types of papers (e.g., methodological or theoretical), effects of independent variables, and use of…

Uses concept mapping to elaborate the content and structure of clients' presenting problems. Employs a meaning-focused examination of problems and seeks to understand and organize obstacles as experienced by clients. Discusses the concept-mapping technique is and presents a two-dimensional concept map of 70 presenting problems. Discusses…

Application of the statistical techniques of survival analysis and credit scoring to private education loans extended to law students found a pronounced seasoning effect for such loans and the robust predictive power of credit bureau scoring of borrowers. Other predictors of default included school-of-attendance, school's geographic location, and…

Considers how relationships with organizational stakeholders are especially problematic for nonprofits in times of planned change. Uses interviews with nonprofit administrators as the basis for the development of six models of implementation communication adopted by nonprofit implementers in interacting with various stakeholder groups. Uses the…

Reviews the growth of public access to computers and the Web; identifies individuals from a national sample of adults who have sought specific information from the Web; identifies individuals who have searched for science or health information; and constructs two models to predict Web use for science and health information. (Author/LRW)

Examined students in foster care for the relationship between learning and extrascholastic environments. Obtained achievement and intelligence scores for children (N=3,483) during the first months of foster care placement. Results showed average to low-average mean achievement and IQ, with academic deficits in basic skill areas. Results support…

Although Sense of Community (SOC) is usually defined as a multidimensional construct, most SOC scales are unidimensional. To reduce the split between theory and empirical research, the present work identifies a multifactor structure for the Italian Sense of Community Scale (ISCS) that has already been validated as a unitary index of SOC. This…

This is the fourth in a series of studies whose purpose has been to develop a theoretical model of selected extramusical variables' ability to explain solo and small-ensemble festival ratings. Authors of the second and third of these (Bergee & McWhirter, 2005; Bergee & Westfall, 2005) used logistic regression as the basis for their…

Bloem and La Heij (2003) reported that in a word-translation task context words induce semantic interference whereas context pictures induce semantic facilitation. This finding was accounted for by a model of lexical access in which: (a) semantic facilitation is localized at the conceptual level, (b) semantic interference is localized at the…

Theories that posit multiplicative relationships between variables are common in psychology. A. G. Greenwald et al. recently presented a theory that explicated relationships between group identification, group attitudes, and self-esteem. Their theory posits a multiplicative relationship between concepts when predicting a criterion variable.…

We investigated sex effects and the effects of educational attainment (EA) on the covariance structure of the WAIS-III in a subsample of the Spanish standardization data. We fitted both first order common factor models and second order common factor models. The latter include general intelligence ("g") as a second order common factor.…

This study incorporated institutional characteristics (e.g., Carnegie type, selectivity) and resource allocations (e.g., instructional expenditures, student affairs expenditures) into a statistical model to predict undergraduate graduation rates. Instructional expenditures, library expenditures, and a number of institutional classification…

Four identity dimensions (Commitment Making, Identification with Commitment, Exploration in Depth, and Exploration in Breadth) were used to derive identity statuses by means of cluster analysis in a sample of late adolescents. This strategy resulted in both a qualitative refinement and a quantitative extension of Marcia's (1966) model. Five…
