Proposes a special rotation procedure for the exploratory dynamic factor model for stationary multivariate time series. The rotation procedure applies separately to each univariate component series of a q-variate latent factor series and transforms such a component, initially represented as white noise, into a univariate moving-average.…

Extends the Triadic Relations Model of C. Bond, E. Horn, and D. Kenny (1997) to analyze the covariances between triadic variables. Specifies a bivariate version of the model and presents estimation methods that can be used to decompose the covariance between 2 triadic variables into 33 covariance components. (Author/SLD)

Seventy-two Israeli emerging adults were interviewed for descriptions of themselves and accounts of their personal, social, and professional dreams, current life status, romantic relationships, and relationships with their parents. Interviews were transcribed and rated on scales assessing self-processes, attainment of professional and romantic…

This article describes how Chernoff faces can be drawn in Microsoft Excel.

The study aimed to find out the impact of tertiary education on development of moderate Islamic society in Pakistan. The population of the study constituted of all the teachers engaged on teaching and all the students studying in the colleges. The study was delimited to the area of public sector college education. Cluster sampling technique was…

The problem investigated in this research study relates to the referral rate for special education evaluations between students of teachers who were exposed to the professional development and resources associated with the federally funded Reading First program and students of teachers who were not exposed to the program. The purpose of this study…

We examine the roles of neighborhood characteristics in the development of the aggressive behavior of 1,409 urban boys and girls between the first and seventh grades. The multilevel, longitudinal growth analyses find strong neighborhood effects in all models, while controlling for individual-level variables. Results indicated that the effects of…

The authors applied I-States as Objects Analysis (ISOA), a recently proposed person-oriented analytic approach, to the study of temperament development in 921 Norwegian children from a population-based sample. A 5-profile classification based on cluster analysis of standardized mother reports of activity, sociability, emotionality, and shyness at…

Rosenthal and Rubin introduced a general effect size index, r[subscript equivalent], for use in meta-analyses of two-group experiments; it employs p values from reports of the original studies to determine an equivalent t test and the corresponding point-biserial correlation coefficient. The present investigation used Monte Carlo-simulated…

This exploratory study measured the efficacy of an emergent literacy intervention program designed to support preschool children who have been identified as having specific language impairments. Specifically, the study compares two intervention approaches--an experimental emergent literacy intervention and a traditional intervention based on…

Following a discussion of activity theory as an approach to human development originally rooted in transformational change, we review the historical context and diverse conceptualizations of social conduct from the field of sociology. The discussion of social conduct is broken into theories of social action, theories of enactment, and contemporary…

A correlation structure modeling method for comparison of mediated effects is outlined. The procedure permits point and interval estimation of differences in mediator effects, and is useful with models postulating 1 or more predictor, intervening, or response variables that may also be latent constructs. The approach allows scale-free evaluation…

In this study, we examined the effectiveness of instructional materials designed to control redundancy and split attention in the teaching of complex orthopedic physical therapy skills. Participants included 41 first-year physical therapy students. The modified instruction group received a modified unit of instruction designed to reduce cognitive…

Childhood apraxia of speech (CAS) is a proposed speech disorder subtype that interferes with motor planning and/or programming, affecting prosody in many cases. Pilot data (Peter & Stoel-Gammon, 2005) were consistent with the notion that deficits in timing accuracy in speech and music-related tasks may be associated with CAS. This study…

This study explored the relationship between person-environment congruence, self-efficacy, and environmental identity and job satisfaction. Participants were 198 employees of a multinational telecommunications corporation. The predictor domain included the lachan Index (R. lachan, 1984), the Mahalanobis Distance Index (L. J. Cronbach & G. C.…
