A positive school climate is an important component of successful and effective schools and thus is often an aim of schoolwide initiatives. Climate has traditionally been conceptualized as a school-level factor and is often assumed to be related to other school-level factors (e.g., school size). The current study examines variation in perceptions…

Background: The study investigated a small range of cognitive abilities, related to visual-spatial intelligence, in adolescents. This specific range of cognitive abilities was termed "graphic abilities" and defined as a range of abilities to visualise and think in three dimensions, originating in the domain of visual-spatial…

The present study examines how exposure to relational aggression at school is associated with adolescents' perceptions of, and participation in, a hostile school environment. Participants were 1,335 African American and European American adolescents in grades 7 through 12 (52% female, 49% African American). Results indicate that exposure to…

Siblings' constructive and unstructured shared activities were examined as moderators of the links between first- and second-born siblings' adjustment across a two-year period in adolescence. Siblings (N = 189 dyads) reported on their depression, peer competency, self worth during home interviews, and their time together in constructive (e.g.,…

Although in-migration and out-migration levels of communities or counties are usually positively correlated, little work has been done on the correlation between in-migration and out-migration within population subcategories. Using a special 1980 data source from the U.S. Census Bureau, this paper examines migration patterns in 30 age/education…

This paper describes and reports on the performance of six related artificial neural networks that have been developed for the purpose of readability analysis. Two networks employ counts of linguistic variables that simulate a traditional regression-based approach to readability. The remaining networks determine readability from "visual…

The most widely used procedures to harness the power of a concomitant (nuisance) variable are block designs and analysis of covariance (ANCOVA). This study attempted to provide a scientific foundation on which to base decisions on whether to block or covary and how many blocks to be used if blocking is selected. Monte Carlo generated data were…

When test-takers are offered a choice of essay questions, some questions may be harder than others. If the test includes a common portion taken by all test-takers, an adjustment to the scores is possible. Previously proposed adjustment procedures disregard the test-makers' efforts to create questions of equal difficulty; these procedures tend to…

This study investigated the correlation between self-concept and reading achievement level in 20 reading-disabled students (mean age 10.3 years, mean grade level 4.75), having average intelligence. Self-concept was assessed using the Piers-Harris Children's Self-Concept Scale and reading achievement level by the Tennessee Comprehensive Assessment…

A study compared the topics addressed in a professional trade publication, the RTNDA (Radio and Television News Directors Association) "Communicator," with topics specifically addressing broadcast news in the scholarly journals "Journalism Quarterly" and "Journal of Broadcasting and Electronic Media." The purpose of…

How the susceptibility perceptions of diverse health risks are reflected in a variety of commonly used likelihood scales (dichotomous, 5-point, 7-point, 9-point, 11-point, and 100-point scales) was examined. Undergraduates (N=103) were asked to rank 12 health risks in the order of likelihood that each problem would happen to them (direct ranking).…

A study examined the relative contributions of age, sex, and education to verbal and nonverbal fluency in a normal population. Sixty-seven subjects aged 12 to 71 years performed paper-and-pencil tasks proven to be dependent on the right and left hemispheric modalities of the frontal lobes. Multiple t-tests were applied to determine whether…

Statistical invariance procedures provide a way of looking at the generalizability of research results from sample to sample when the research has not been validated by replication. This paper discusses the Procrustean Rotation invariance procedure following a canonical correlation analysis. The computer program RELATE is used to gauge the…

In order to determine if the pH of archival storage boxes decreases over time, experimental research was performed by sampling 25 Hollinger, one cubic foot, archival storage boxes from the Kent State University (Ohio) Archives. Boxes chosen for testing were new, 5, 10, 15, and 20 years old. Each box was tested for pH value using pH pens and a cold…

The AGS Early Screening Profiles (AGS:ESP) instrument (P. Harrison, 1990) has been introduced recently as a screening instrument for predicting mental ability. A study was conducted to determine the degree of concurrent validity between the AGS:ESP and the Stanford Binet Fourth Edition (SB:FE), an instrument often used by psychologists to detect…
