Monte Carlo methods were used to estimate the power of randomization tests used with single-case designs involving random assignment of treatments to phases. Simulations of two treatments and six phases showed an adequate level of power when effect sizes were large, phase lengths exceeded five, and autocorrelation was not negative. (SLD)

Investigates user participation in the development of collaborative work systems that use technology. Discusses collaborative versus non-collaborative applications; explains design issues that enhance user satisfaction and productivity; and considers how much users should participate in information needs analysis and in systems analysis issues.…

Examined free recall narratives of younger and older children and their parents independently interviewed about injuries requiring hospital emergency treatment. Found that mothers' narratives were more cohesive and coherent than fathers', and girls' narratives differed from boys' in parallel ways. Parent and child measures were correlated;…

Presents two methods for evaluating automatically generated hypertext links: one is based on correlations between shortest paths in the hypertext structure and a semantic similarity measure, and the other is based on measuring users' performances using hypertext. Advantages and disadvantages of computer versus human evaluation are discussed.…

Examines the relationship of age and two dimensions of self-esteem using a national sample of adults in the United States. Findings indicate that those over age 65 experience heightened levels of self-esteem, especially on self-efficacy, compared to their younger counterparts. Implications for findings are discussed. (RJM)

Examined the school performance, suicidal involvement, disordered eating behaviors, pregnancy risk, and chemical use of female teenagers with a history of sexual abuse. Found that they reported higher rates of adverse outcomes than did teenagers without a background of abuse. Lists protective factors and risk factors that influenced outcomes. (RJM)

Explored the concurrent validity of two measures given to students with disabilities who underwent special education assessment. Three years after tests were administered to 44 adolescents, correlations among the total and the subscale scores of these measures were high and statistically significant, excluding the difference between a verbal…

Introduces three new metrics that measure the range of use of a university Web site by its peers through different heuristics for counting links targeted at its pages. Results from all three range models that were tested on United Kingdom university Web sites correlate significantly with the research productivity of the target institution.…

Examined relation of maternal monitoring and play rules to sixth graders' friendship quality, social behavior, and depression. Found that monitoring was not related to supervision, peer, or restriction play rules. Girls with more monitoring had friendships with less conflict and higher positive qualities. Supervision rules related to boys'…

Used data from a state report card to determine which variables characterize bivariate and multivariate relationships between school quality indicator variables and academic status in high and low socioeconomic status schools and high and low achievement schools. Data from 1,319 schools provide information that may help meet the needs of at-risk…

This study compared college students at various levels of academic persistence and achievement. Previous high school achievement and preference for complex explanations of behavior are the best correlates with persistence and achievement. Other correlates include effective time management and recognition of the influence of social contexts on…

Presents nine guidelines for structuring instructional presentations on all grade levels so that student achievement will be enhanced and lists the correlational and experimental research studies on which the guidelines are based. The importance of precision and structure is emphasized. (119 references) (LRW)

The relationship between identity and intimacy development was studied using 71 male and 71 female college students over a 5-week period using 3 theoretical models reflecting possible gender distinctions. Cross-lag panel correlation investigated the validity of the models. Evidence in support of the models is evaluated. (SLD)

Discussion of the use of computer programing languages to facilitate cognitive skill transfer focuses on logical reasoning. Conditional logic principles are examined, and a study is described that examined the effects of learning the LOGO Programing Language on fifth graders' conditional reasoning abilities. (35 references) (LRW)

Teachers with strict standards more frequently refer students with low levels of aggression to special education than do teachers with lax standards. The opposite is true for students with high levels of aggressive behavior. Teacher gender also correlates with decisions on special education referrals. (IAH)
