This study investigated the factor structure of the 10 subtests of the Career Maturity Inventory (CMI). Although two principal factors emerged, the CMI Competence and Attitude subtests did not load distinctly on the two separate factors. Results also tended to indicate that the discriminant validity of the CMI may be minimal. (PN)

Initial standing in language, reading, intelligence, socioeconomic status, and sex differences did not predict writing ability of third grade children any more accurately for structured than for nonstructured teaching methods, although children who did not spell or read as well as others were able to produce more volume in their writing when…

Recent years it has an explosive development of IT technologies. However, the problem of natural integration of modern technologies in teaching and learning mathematics is far from its final solution. In teaching mathematics at universities, these capabilities either are ignored or have extremely limited applications. In our study, we consider…

On the basis of a large-scale survey of high-school youth, the authors compared adolescents reporting exclusively heterosexual, mostly heterosexual, bisexual, and predominately same-sex attraction based on high-risk involvement across a range of risk behaviors. Bisexual and same-sex attracted groups were characterized by heightened high-risk…

Survival analysis is a statistical tool used to describe the duration between events. Many processes in medical research, engineering, and economics can be described using survival analysis techniques. This research involves studying engineering college student graduation using Cox proportional hazards models. Among male students with American…

This study examined the influence of surrogate gender on the accuracy of substituted judgments about the use of life-sustaining treatment in a sample of 249 older adults and their self-selected surrogate decision-makers. Overall, wives were more accurate than husbands at predicting their spouses' treatment wishes. Surrogates' perceptions of their…

The persistence of Black engineering students to graduation from college continues to be of concern as the nation moves into a more globally diverse environment. Institutions have a large role to play to ensure that there is a large pool of diverse and talented students trained to work in a technological environment. While our population has…

This study investigated whether previously reported links between sleep and risk taking among adolescents (E. M. O'Brien & J. A. Mindell, 2005) are associated--concurrently, longitudinally, or both--with sleep or underlying depression. The present study analyzed data from a nationally representative sample of 4,353 adolescents in the United…

Cognitive abnormalities are common in Parkinson's disease, with important social and economic implications. Factors influencing their evolution remain unclear but are crucial to the development of targeted therapeutic strategies. We have investigated the development of cognitive impairment and dementia in Parkinson's disease using a longitudinal…

The influence of homework experiences on students' academic grades was studied with 223 college students. Students' self-efficacy for learning and perceived responsibility beliefs were included as mediating variables in this research. The students' homework influenced their achievement indirectly via these two self-regulatory beliefs as well as…

This study examined the extent to which violent behavior and peer victimization were associated with suicidal ideation, plans, and attempts in a nationally representative sample of 11,113 adolescents who completed the 2005 Youth Risk Behavior Survey. Boys were more likely to be involved in physical fighting and weapon carrying, whereas girls were…

This study tested the hypothesis that self-efficacy in career roles moderates the relation between perception of career barriers and career planning, in a study with Portuguese students, 488 in Grade 9 and 517 in Grade 12. The results supported the hypothesis only among Grade 9 girls, showing that perception of career barriers leads to less career…

This study investigated the effect of personalized print-based instruction on the achievement and self-efficacy regarding mathematics word problems of 320 senior secondary students in Nigeria. The moderator effect of gender was also examined on independent variable (personalization) and dependent variables (mathematics word problem achievement and…

The aim of the present study was to simultaneously examine the effect of factors related to school, leisure, family and the individual on adolescent smoking. These determining factors occupy the micro- and mesosystems of Bronfenbrenner's Ecological Theory. Data were collected using questionnaires from a nationally representative sample of…

This study sought to develop a regression model to predict maximal oxygen uptake (VO[subscript 2max]) based on submaximal treadmill exercise (EX) and non-exercise (N-EX) data involving 116 participants, ages 18-65 years. The EX data included the participants' self-selected treadmill speed (at a level grade) when exercise heart rate first reached…
