This paper focuses on three aspects related to the conceptualization and application of canonical correlation analysis as a dominant statistical model: (1) partial canonical correlation analysis and its application in statistical testing; (2) the relation between canonical correlation analysis and discriminant analysis; and (3) the relation…

Examined subgroups of people in relation to specific types of drugs. Multiple drug clusters identified here yielded six basic drug clusters. Typology of drug abusers was developed by proximity cluster analysis. Set of psychosocial measures was differentially related to use of types of drugs and drug abusers. (Author/BEF)

The prevalence of epilepsy was correlated with the severity and type of encephalopathy of 1,023 individuals with mental retardation. A total of 326 individuals were diagnosed with epilepsy. Results indicated a low percentage of epilepsy in chromosomic-genetic and young adult encephalopathies and a high prevalence when the neurodeficit was…

This study explores how neighborhood context influences participation in local social organization through a multilevel-spatial analysis of residents in Chicago neighborhoods. We construct a typology of community participation based on two dimensions: instrumental vs. expressive motivations for participation and formal vs. informal modes of…

We investigated the relationship between reading and explicit and implicit categorical learning by comparing university students with poor reading to students with normal reading abilities on two categorical learning tasks. One categorical learning task involved sorting simple geometric shapes into two groups according to a unidimensional rule.…

A self-paced reading experiment investigated processing of sentences containing a noun-phrase that could temporarily be mistaken as the direct-object argument of a verb in a subordinate clause but actually constituted the syntactic subject of the main clause (often referred to as an "early" vs. "late closure" ambiguity). Subcategorization…

This article uses a program-level evaluation to assess the characteristics of smaller-scale project evaluations and their use for project improvement and accountability purposes. The authors used available information from the annual Advanced Technological Education (ATE) program evaluation surveys to describe the characteristics of evaluation…

This study examines the interaction between learning styles and academic performance in an anatomy course that blends traditional lecture with an array of hands-on activities. Participants were 19 students (ranging from 18 to 24 years of age) at Columbia College, Chicago. The Felder-Silverman Index of Learning Styles and a 25-item pre-test and…

This study examined the generality of the logarithmic to linear transition in children's representations of numerical magnitudes and the role of subjective categorization of numbers in the acquisition of more advanced understanding. Experiment 1 (49 girls and 41 boys, ages 5-8 years) suggested parallel transitions from kindergarten to second grade…

To develop a taxonomy of Cross Examination Debate Association (CEDA) critics, a study associated professed judging philosophy and responses to survey questions with ballot behavior and elaborated judging profiles. Subjects were debate critics who judged rounds at CEDA tournaments in the Northeast during the Spring 1989 season. In all, 13 critics…

The nature of the criterion (dependent) variable may play a useful role in structuring a list of classification/prediction problems. Such criteria are continuous in nature, binary dichotomous, or multichotomous. In this paper, discussion is limited to the continuous normally distributed criterion scenarios. For both cases, it is assumed that the…

CLASSIFICATION OF DOCUMENTS INVOLVES THREE DISTINCT PROCESSES-- (1) DEFINING A STRUCTURE OF CATEGORIES, (2) DETERMINING A BASIS FOR A CLASSIFICATION DECISION, AND (3) CLASSIFYING DOCUMENTS INTO CATEGORIES. OF THE THREE COMPUTER TECHNIQUES ARE DISCUSSED FOR THE LAST TWO. A WORD SELECTION MEASURE IS USED TO DELETE THOSE TERMS IN THE DOCUMENT THAT…

This report discusses the problem of the meansings of words used in information retrieval systems, and shows how semantic tools can aid in the communication which takes place between indexers and searchers via index terms. After treating the differing use of semantic tools in different types of systems, two tools (classification tables and…

Results of a study investigating the extent of relationship between inventoried interests using the SVIB and expressed interests coded using each of the vocational classification schemes suggested by Holland, Roe, and Strong is reported. Expressed vocational choice as well as scores on 35 of the Strong Vocational Interest Blank (SVIB) were…
