Different models of spoken word production make different predictions regarding the extent of effects of certain word properties on the output of that model. This article examines these predictions with regard to the effect of these variables on the production of semantic and phonological errors by aphasic subjects. (60 references) (Author/CK)

A person-situation interactionist theory to explain Australian student decisions to pursue higher education is advanced and a model is tested using data from Victoria and Queensland. Results of statistical analyses are generally consistent with expectations. Certain interactive effects of variables in the model are examined. (Author/MSE)

Tested stress-problem-solving and stress-social support models in etiology of depressive symptoms, hopelessness, and suicide ideation for Asian international students (n=101). Hypothesized problem-solving skills and social support as mediators between life stress and depressive symptoms, hopelessness, and suicide ideation. Results supported…

This investigation at California State University, Chico seeks to identify those variables that prove indicative of the demand for monographs by subject. Analyzes interrelationships among circulation, expenditure, and enrollment by subject and develops a model for allocating subject funding based on circulation statistics. (Author/LRW)

Tested model relating girls' pubertal timing to mothers' history of psychopathology, mediated by family discord and father absence/stepfather presence. Found that mothers' history of mood disorders predicted earlier daughters' puberty, with the relation fully mediated by dyadic stress and biological father absence. Stepfather presence best…

Examines responses of 40,435 students from the "Youth Risk Behavior Surveillance Survey" and uses student self-reported school risk behaviors to "predict" recent weapon possession at school. Although school risk behaviors were moderately correlated with school weapon possession, many frequent weapon carriers displayed zero…

This investigation examined relationship stability among 60 women court-mandated to violence interventions by applying a general model (i.e., Rusbult's 1980 Investment Model) to predict intentions to leave current relationships. As in past research, results showed that Investment Model predictions were supported such that court-mandated women who…

The current study attempts to differentiate effects of phonotactic probability (i.e. the likelihood of occurrence of a sound sequence), neighbourhood density (i.e. the number of phonologically similar words), word frequency, and word length on expressive vocabulary development by young children. Naturalistic conversational samples for three…

Many proponents of school choice use the claim of the market's capability to enhance efficiency and improve performance to call for its expansion. But no markets are perfectly competitive, and the local market for public goods is filled with institutional arrangements that make it differ from the neoclassical ideal. In this paper, we look at a…

The authors test biosocial models that posit interactions between biological variables (testosterone, estradiol, pubertal status, and pubertal timing) and social context variables (family, peer, school, and neighborhood) in predicting adolescent involvement with cigarettes and alcohol in a sample of 409 adolescents in Grades 6 and 8. Models…

This study applied the methodology of competing risks survival analysis to determine the probability that a student's first enrollment in the university will end in graduation, transfer, or withdrawal. The risk factors associated with each mode of exit were assessed, with attention to factors such as admission status, full-time or part-time…

This study used Markov chain matrices to simulate the effect of varying degrees of change in student characteristics on retention and graduation rates. Data were applied to a 1-year enrollment transition matrix that tracks how students of each class level progress into the same or higher class levels, to a completed degree, or to non-returning…

Four primary tasks were conducted for this two-phase study, which examined the outcomes to challenged library materials in terms of retention, restriction, and removal, and identified key factors that influenced the outcome: (1) the relevant research literature was reexamined and a conceptual model for testing based on the research literature was…

Eighth-grade students (n=42) were observed during five different life science problem-solving activities. Student interactions and thinking skills were recorded in relation to the problem-solving steps. A causal model was hypothesized and tested using path analysis procedures. The hypothesized causal model was adjusted based on path coefficients…

The Double ABCX Model of Family Adjustment and Adaptation, a model that predicts adaptation to chronic stressors on the family, was extended by dividing it into attitudes, coping, and adaptation of parents and child separately, and by including variables relevant to child adaptation to epilepsy or asthma. The extended model was tested on 246…
