Steinberg and Monahan's (2011) reanalysis of the Teen Media longitudinal survey of adolescents does not meet prevailing standards for propensity score analysis and therefore does not undermine the original conclusions of the Brown, L'Engle, Pardun, Guo, Kenneavy, and Jackson (2006) analysis. The media do matter in the sexual socialization of…

Maxwell, Cole, and Mitchell (2011) demonstrated that simple structural equation models, when used with cross-sectional data, generally produce biased estimates of meditated effects. I extend those results by showing how simple structural equation models can produce biased estimates of meditated effects when used even with longitudinal data. Even…

Study assessed compliance and internalization for 99 preschoolers previously studied as toddlers. Compliance and internalization were assessed in multiple observational contexts using maternal reports. Found that committed and situational compliance had distinct developmental trajectories, and only committed compliance was associated with…

Five years of state test results for Pennsylvania are examined, focusing on differences among elementary schools in which a majority of students do not master basic learning skills. Data are provided for 1,505 elementary schools in about 500 districts. The largest learning problems occur in about 10% of the schools; these schools have been…

This collection of reports on the measurement and meaning of unemployment consists of 13 papers devoted to some of the deficiencies in youth employment statistics, some of the necessary considerations in their implications, and many of the issues involved in their application to assess program impacts. Analyzed first are the youth labor force…

Research on reading has tried, and failed, to account for wide disparities in reading skill even among children taught by the same method. Why do some children learn to read easily and quickly while others, in the same classroom and taught by the same teacher, don't learn to read at all? In "Language Development and Learning to Read", Diane…
