Recent research suggests that witnessing events of fission (e.g., the splitting of a solid object) impairs human infants', human adults', and non-human primates' object representations. The present studies investigated the reactions of gorillas and orangutans to cohesion violation across different types of fission events implementing a behavioral…

Research leadership, a much neglected area of educational leadership and management, is disadvantaged by having an underdeveloped and inadequate knowledge base. This article represents a contribution to this knowledge base through a conceptual analysis. It presents as propositional knowledge an original theoretical model of the componential…

The aim of this report was to investigate the associations between attachment state of mind, romantic attachment style, and indices of maternal functioning in two relational spheres: the mother-child relationship (i.e., maternal sensitivity and child attachment security) and the marital relationship (i.e., mothers' and their partners' marital…

The organized camp experience has been an important part of the lives of children, youth, and adults for over 150 years and is a social institution that touches more lives than any other except for schools. Camp is more than a location or a program; it encompasses the affective, cognitive, behavioral, physical, social, and spiritual benefits that…

This study examines the perceptions of teachers and other professionals of Team-Teach behaviour support training in New Zealand. Analysis of course evaluations, questionnaires, interviews and documents provide the findings. Comparisons are made with Team-Teach training in the UK and similarities and differences between New Zealand training…

This study exploits a randomized trial of two light-touch elementary school interventions to estimate long-run impacts on postsecondary attendance and attainment. The first is a classroom management technique for developing behavioral skills in children. The second is a curricular intervention aimed at improving students' core reading skills. We…

The effects of a school-based social-emotional and character development program, "Positive Action," on the developmental trajectory of character development was evaluated using data from three randomized trials. Results come from (1) 4-years of data from elementary children in 20 Hawai'i schools, (2) 3-years of data from elementary…

Early adolescence is the period where the transition from child to adult takes place gradually. A major physical and cognitive change during this period is accompanied by social and emotional development. The growth spurt in this period makes them stronger and plays an important role in developing self identities. The journey through this crucial…

What we're thinking about behaviorally challenging students and what we're doing to them requires a fresh look. When schools believe that parental discipline explains a child's misbehavior, educators are less likely to consider different explanations for the misbehavior and the full range of interventions that could be implemented at school. And…

A study examines whether genetic variation in dopamine pathways differentially associate with smoking progression in adolescence. Results indicate the influence of specific dopamine genes in different stages of smoking progression in adolescents.

In this paper, we combine neurological and developmental evidences in order to differentiate between two levels of sharing: dyadic sharing, virtually present from birth and depending on the activation of shared representation, and triadic sharing, requiring that agents not only share a common representation, but also represent complementary…

Lately, a deliberative conception of democracy has gained influence in policy debates throughout Europe. Individuals are here seen to be fostered into responsible, mature--democratic--citizens by being involved in dialogue. In the 1990s, calls for "democratic education" intensified in Sweden. This article analyses two pedagogical models…

In May 2010, the Center for Juvenile Justice Reform (CJJR) at Georgetown University released the monograph "Addressing the Unmet Educational Needs of Children and Youth in the Juvenile Justice and Child Welfare Systems" (Leone & Weinberg, 2010). The monograph examined a number of topics relevant to the education and experiences of…

This article, using longitudinal data from the National Child Development Study, presents new evidence on the effects of family size and birth order on test scores and behavioral development at age 7, 11 and 16. Sibling size is shown to have an adverse causal effect on test scores and behavioral development. For any given family size, first-borns…

Do interventions work and for whom? For this article, we examined the influence of population heterogeneity on power in designing and evaluating interventions. On the basis of Monte Carlo simulations in Study 1, we demonstrated that the power to detect the overall intervention effect is lower for a mixture of two subpopulations than for a…
