Electrostatic backscattering by insulating obstacles
2012
AbstractWe introduce and analyze backscattering data for a three-dimensional obstacle problem in electrostatics. In particular, we investigate the asymptotic behavior of these data as (i) the measurement point goes to infinity and (ii) the obstacles shrink to individual points. We also provide numerical simulations of these data.
Career goal-related social ties during two educational transitions: Antecedents and consequences
2010
Abstract This study examined adolescents’ career goal-related social ties during the transition from compulsory to post-compulsory education and during transition from post-compulsory education to working-life or further studies. A total of 687 Finnish adolescents aged 15–16 were surveyed of whom 654 also participated at the second measurement point one year later, and 497 three years later. Differences in career goal-related social ties were found according to gender, GPA, family structure, and SES. Moreover, social ties were associated with educational track after compulsory school above and beyond SES, GPA, and family structure. Adolescents who named a teacher or a romantic partner were …
Math homework : Parental help and children’s academic outcomes
2019
In the present study, we examined the longitudinal relations between child-perceived parental help with math homework (i.e., support and control), children's math skills, and mother-reported task persistent behavior in homework situations. A total of 624 mother–child dyads were followed across Grade 6 and Grade 9, controlling for Grade 3 variables. At each measurement point, children completed math tests, and their mothers evaluated task persistence during homework. In Grades 6 and 9, children reported their perceptions of their parents’ help with math homework. First, the results showed that perceived support in Grade 6 predicted an increase in persistence during homework in Grade 9. Secon…
