Abstract The objective was assess the influence of untreated caries and socioeconomic status (SES) on school dropout among adolescents. A six-year cohort study conducted with random sample adolescents (12 years-old) who had been evaluated initially in 2012 from Santa Maria, Brazil. Sex, (mother’s education household income), were collected at baseline. outcome variable follow-up through self-re...

This paper focuses on university-level education offered by methods of distance learning in the field of computers and aims at the investigation of the main causes for student dropouts. The presented study is based on the students of the Course of ‘‘Informatics’’, Faculty of Science and Technology of the Hellenic Open University and investigates the particularities of education provided through...

[1] During 124 high-speed-stream-driven storms from two solar cycles, a multispacecraft average of the 1.1–1.5 MeV electron flux measured at geosynchronous orbit is examined to study global dropouts of the flux. Solar wind and magnetospheric measurements are analyzed with a superposed epoch technique, with the superpositions triggered by storm-convection onset, by onset of the relativistic-elec...

BACKGROUND Monitoring and evaluation (M&E) of HIV care and treatment programs is impacted by losses to follow-up (LTFU) in the patient population. The severity of this effect is undeniable but its extent unknown. Tracing all lost patients addresses this but census methods are not feasible in programs involving rapid scale-up of HIV treatment in the developing world. Sampling-based approaches an...

We report on the i-dropouts detected in two exceptionally deep ACS fields (B435, V606, i775, and z850 with 10σ limits of 28.8, 29.0, 28.5, and 27.8, respectively) taken in parallel with the UDF NICMOS observations. Using an i− z > 1.4 cut, we find 30 i-dropouts over 21 arcmin down to z850,AB = 28.1, or 1.4 i-dropouts arcmin, with significant field-to-field variation (as expected from cosmic var...

OBJECTIVES This study sought to identify early predictors of adolescent violence and to assess whether they vary by sex and across different types and levels of violence. METHODS Data from a 5-year longitudinal self-report survey of more than 4300 high school seniors and dropouts from California and Oregon were used to regress measures of relational, predatory, and overall violence on predict...
