RESUMEN
The description of the local turbulent energy transfer and the high-resolution ion distributions measured by the Magnetospheric Multiscale mission together provide a formidable tool to explore the cross-scale connection between the fluid-scale energy cascade and plasma processes at subion scales. When the small-scale energy transfer is dominated by Alfvénic, correlated velocity, and magnetic field fluctuations, beams of accelerated particles are more likely observed. Here, for the first time, we report observations suggesting the nonlinear wave-particle interaction as one possible mechanism for the energy dissipation in space plasmas.
RESUMEN
OBJECTIVE: Undocumented Haitian migrants to the Dominican Republic often live in impoverished communities called bateyes. These contexts present challenges for adolescent sexual health education. To inform development of appropriate adolescent education programs, this study assessed their general sexual health knowledge. METHODS: A locally developed sexual health knowledge survey was administered to 930 grade 7-12 adolescents attending six batey schools. Analysis of aggregated responses reviewed general demographics (e.g. age and sex), and identified top community sexual health concerns and most trusted information sources. RESULTS: Top concerns included menstruation (25.5%), HIV (21.8%), and family planning (13.3%); stratification by sex identified discordance around menstruation (89.2% female, 10.8% male) and HIV (67.1% male, 32.9% female), but not family planning (47.2% male, 52.8% female). Parents were identified as the most trusted information source, irrespective of concern. CONCLUSION: Community concerns around menstruation matches extant developing-world literature that links menarche with female stigma and school absence. Interest in HIV and family planning suggests targeted promoted efforts would be of benefit. Trust in parents is reflective of cultural traditions and suggests potential knowledge impacts arising from effective parental education.
