High School Dropouts and Sexually Transmitted Infections.
People who drop out of high school fare worse in many aspects of life. We analyze the relationship between dropping out of high school and the probability of contracting a sexually transmitted infection (STI). Previous studies on the relationship between dropout status and sexual outcomes have not empirically addressed unobserved heterogeneity at the individual level. Using fixed effects estima...
متن کاملEvaluation of indicated suicide risk prevention approaches for potential high school dropouts.
OBJECTIVES This study evaluated the efficacy of 2 indicated preventive interventions, postintervention and at 9-month follow-up. METHODS Drawn from a pool of potential high school dropouts, 460 youths were identified as being at risk for suicide and participated in 1 of 3 conditions randomly assigned by school: (1) Counselors CARE (C-CARE) (n = 150), a brief one-to-one assessment and crisis i...
متن کاملAdjusting sample size for anticipated dropouts in clinical trials.
Statistical models for calculating sample sizes for controlled clinical trials often fail to take into account the negative impact that dropouts have on the power of intent-to-treat analyses. Empirically defined dropout correction coefficients are proposed to adjust sample sizes for endpoint analysis of variance (ANOVA) and analysis of covariance (ANCOVA) that have been initially calculated ass...
متن کاملCloning Dropouts : Implications for Galaxy Evolution at High Redshift
The evolution of high redshift galaxies in the two Hubble Deep Fields, HDF-N and HDF-S, is investigated using a cloning technique that replicates z ∼ 2 − 3 U dropouts to higher redshifts, allowing a comparison with the observed B and V dropouts at higher redshifts (z ∼ 4 − 5). We treat each galaxy selected for replication as a set of pixels that are k-corrected to higher redshift, accounting fo...
متن کاملClinical observation of high-risk children.
Systematic observations of the behavior of high-risk and control children were made during the clinical interview, the neurological examination, psychometric testing, and the experimental psychological test battery. Children were unaware that observations of them were being made and recorded. In all four examination settings, index children were seen as impaired relative to control children in ...
