Although the role of education in an economy is emphasized in theoretical studies, empirical literature finds mixed results for the relationship between growth and education. We examine the relationship between Gross Domestic Product (GDP) and enrollments in primary, secondary, and high schools, as well as universities in Turkey for 1937-1996, in…

Objectives: To determine the incidence of and risk factors associated with infant (less than 1 year of age) physical abuse in Alaska. Methods: A population-based retrospective cohort study for the 1994-2000 resident birth cohort was conducted by linking data from birth certificates, Child Protective Services, a statewide hospital-based trauma…

The research to explain students' self-regulated learning has grown rapidly in recent years. However, the studies on self-regulated learning have shown fascinating but mixed results. Thus, there is a need to identify and describe the key dimensions of self-regulated learning according to an empirical framework in order to integrate these complex…

The study explored whether children with high functioning autism (HFA), Asperger syndrome (AS), and pervasive developmental disorder not otherwise specified (PDD-NOS) can be differentiated on the Children's Communication Checklist (CCC). The study also investigated whether empirically derived autistic subgroups can be identified with a cluster…

The present experiments assessed the effects of different manipulations between cue preexposure and cue-outcome pairings on latent inhibition (LI) in a predictive learning task with human participants. To facilitate LI, preexposure and acquisition with the target cues took place while participants performed a secondary task. Presentation of…

According to biological indicators trends in young people's health appear favourable, but the psychosocial aspects suggest a different pattern. We studied the differences across schools in common health complaints and in three groups of factors behind them: pupils' individual characteristics, family related factors and school-related factors.…

The authors compare the operating characteristics of the bootstrap-F approach, a direct extension of the work of Berkovits, Hancock, and Nevitt, with Huynh's improved general approximation (IGA) and the Brown-Forsythe (BF) multivariate approach in a mixed repeated measures design when normality and multisample sphericity assumptions do not hold.…

Mathematics performance at 7 years as assessed by teachers using UK national curriculum criteria has been found to be highly heritable. For almost 3000 pairs of 7-year-old same-sex twins, we used multivariate genetic analysis to investigate the extent to which these genetic effects on mathematics performance overlap with genetic effects on reading…

This study investigated fourth grade students' perceptions of abilities to use the Internet. The 31-item research instrument measuring Internet Self-Perceptions was adapted for use from the Reader Self-Perception Scale (RSPS) developed by Henk and Melnick (1995). The RSPS survey was based upon Bandura's (1977, 1986, 1995) research in the areas of…

We describe a principled way of imposing a metric representing dissimilarities on any discrete set of stimuli (symbols, handwritings, consumer products, X-ray films, etc.), given the probabilities with which they are discriminated from each other by a perceiving system, such as an organism, person, group of experts, neuronal structure, technical…

There is growing evidence that the current method of identifying students with a learning disability (LD) is ineffective. The wait-to-fail model of assessing students after second/third grade as well as conceptual problems in using intelligence tests for identification result in students not receiving the assistance they need during the…

This study aimed at comparing the effectiveness of problem-based learning (PBL) and traditional lecture-based instruction on elementary school students' academic achievement and performance skills in a science unit on genetics while controlling for their reasoning ability. For the specified purpose, two instructional methods were randomly assigned…

This research study explores the policy expansion of school choice within the methodological approach of event history analysis. The first section provides a comparative overview of state adoption of public school choice laws. After creating a statistical portrait of the contemporary landscape for school choice, the authors introduce event history…

This study dealt with advice and help-seeking intentions of Jewish and Arab youth in Israel toward family, friends, and professionals in relation to their interpersonal relationships with family and friends. The random sample consisted of 865 participants: 653 Jewish and 212 Arab youths. Four original instruments were used. The first consisted of…

This study investigated the effects of gameplaying on fifth-graders' maths performance and attitudes. One hundred twenty five fifth graders were recruited and assigned to a cooperative Teams-Games-Tournament (TGT), interpersonal competitive or no gameplaying condition. A state standards-based maths exam and an inventory on attitudes towards maths…
