The objective of this study was to describe comprehensively the structure and process of the childhood mealtime environment. A socioeconomically diverse sample of 142 families of kindergarteners (52% females) was observed at dinnertime using a focused-narrative observational system. Eighty-five percent of parents tried to get children to eat more, 83% of(More)
Studies show that children who use relational aggression process social information in unique ways; however, findings have been inconsistent and limited by methodological weaknesses. This short-term longitudinal study examined developmental changes in 245 (49% female; ages 8-13) 3rd through 8th graders' normative beliefs about relational aggression and(More)
Diameter effect and front curvature measurements are reported for rate stick experiments on commercially available prilled ANFO (ammonium-nitrate/fuel-oil) at ambient temperature. The shots were fired in paper tubes so as to provide minimal confinement. Diameters ranged from 77 mm (« failure diameter) to 205 mm, with the tube length being ten diameters in(More)
Response bias shows up in many fields of behavioural and healthcare research where self-reported data are used. We demonstrate how to use stochastic frontier estimation (SFE) to identify response bias and its covariates. In our application to a family intervention, we examine the effects of participant demographics on response bias before and after(More)
Accurate, early screening is a prerequisite for indicated interventions intended to prevent development of externalizing disorders and delinquent behaviors. Using the Fast Track longitudinal sample of 396 children drawn from high-risk environments, the authors varied assumptions about base rates and examined effects of multiple-time-point and multiple-rater(More)
Nine Holtzman rats were maintained from days 5-18 of pregnancy on a liquid diet of which ethanol constituted 35% of the calories while nine rats were pair-fed an isocaloric diet that had maltose-dextrin substituted for the ethanol. Beginning on day 19 of gestation and continuing for five days the dams in both groups were given a choice among lab chow,(More)
