The Silent Epidemic: Perspectives of High School Dropouts

Presents findings from a survey that examines why some students do not complete their high school education, and what academic and personal supports would have helped them stay in school. Includes recommendations for improving graduation rates

Factors associated with pregnancy and STI among Aboriginal students in British Columbia.

BACKGROUND: Aboriginal adolescents are more likely to become pregnant and contract an STI than other Canadian adolescents. This study provides some of the first data on factors associated with these outcomes among Aboriginal adolescents. METHODS: A secondary analysis was conducted using 2003 data from a large cross-sectional survey of British Columbia secondary school students. 445 young women and 360 young men who identified as Aboriginal and reported ever having sex were included in analyses. Associations between self-reported pregnancy and STI and 11 exposure variables were examined using logistic regression. RESULTS: Of young women, 10.6% reported a pregnancy; 10.5% of young men reported causing a pregnancy. An STI diagnosis was reported by 4.2% of young women and 3.9% of young men. In multivariate analyses for young men, ever having been sexually abused was the strongest consistent risk factor for causing a pregnancy (AOR = 4.30, 95% CI 1.64-11.25) and STI diagnosis (AOR = 5.58, 95% CI 1.61-19.37). For young women, abuse was associated with increased odds of pregnancy (AOR = 10.37, 95% CI 4.04-26.60) but not STI. Among young women, substance use was the strongest consistent risk factor for both pregnancy (AOR = 3.36, 95% CI 1.25-9.08) and STI (AOR = 5.27, 95% CI 1.50-18.42); for young men, substance use was associated with higher odds of STI (AOR = 4.60, 95% CI 1.11-19.14). Factors associated with decreased risk included community, school and family involvement. CONCLUSIONS: Health care professionals, communities and policy-makers must urgently address sexual abuse and substance use. Exploring promotion of school and community involvement and family cohesion may be useful for sexual health interventions with Aboriginal students

Audio-guided mindfulness training in schools and its effect on academic attainment: Contributing to theory and practice

We report the results of a randomized trial (N = 337) examining the effectiveness of a daily audio-guided MBI in raising academic achievement in 16 volunteer classrooms across two socio-demographically diverse United States primary schools. The study's findings were that, over the intervention period, improvements in Math scores, Social Studies scores and Grade Point Averages (GPA) were generally higher for students in intervention classrooms. However, confidence intervals were wide and there was pre-existing variability between schools and grades, resulting in few significant differences as a result of the intervention and generally low effect sizes. Through a careful discussion of the study's results, the paper contributes to theory by generating a comprehensive agenda for follow-up research. The study also contributes to practice by reporting on the effectiveness of technology-enabled mindfulness training because participating teachers seemed able to implement the intervention with almost no further training or need for hiring external mindfulness experts

Elevation of the Diaphragm; Unilateral Phrenic Paralysis: A Radiological Study, with Special Reference to the Differential Diagnosis

My thesis is mainly a radiological study of Elevation of the diaphragm with some observations on the differential diagnosis. I have added to the title that of Unilateral phrenic paralysis for two reasons; firstly, I hope to show during the course of this paper that certain forms of congenital elevation of the diaphragm are probably due to a unilateral phrenic paralysis, and secondly, to present for consideration a number of cases in which paralysis of one or other leaflet of the diaphragm was caused by a definite pathological lesion involving the phrenic nerve in its pasage through the thorax

Atomic oxygen studies on polymers

The purpose was to study the effects of atomic oxygen on the erosion of polymer based materials. The development of an atomic oxygen neutral beam facility using a SURFATRON surface wave launcher that can produce beam energies between 2 and 3 eV at flux levels as high as approx. 10 to the 17th power atoms/cm (2)-sec is described. Thin film dielectric materials were studied to determine recession rates and and reaction efficiencies as a function of incident beam energy and fluence. Accelerated testing was also accomplished and the values of reaction efficiency compared to available space flight data. Electron microscope photomicrographs of the samples' surface morphology were compared to flight test specimens

Arctic–CHAMP: A program to study Arctic hydrology and its role in global change

The Arctic constitutes a unique and important environment that is central to the dynamics and evolution of the Earth system. The Arctic water cycle, which controls countless physical, chemical, and biotic processes, is also unique and important. These processes, in turn, regulate the climate, habitat, and natural resources that are of great importance to both native and industrial societies. Comprehensive understanding of water cycling across the Arctic and its linkage to global biogeophysical dynamics is a scientific as well as strategic policy imperative
