The present study analyzes morphological differences femora of contemporary Japanese and Western Australian individuals and investigates the feasibility of population affinity estimation based on computed tomographic (CT) data. The latter is deemed to be of practical importance because most anthropological methods rely on the assessment of aspects of skull morphology, which when damaged and/or unavailable, often hampers attempts to estimate population affinity. The study sample comprised CT scans of 297 (146 females; 151 males) Japanese and 330 (145 females; 185 males) Western Australian adult individuals.

The Japanese and Western Australian samples comprise CT scans of 207 (103 females; 104 males) and 158 (78 females; 80 males) adult individuals, respectively. Following volumetric reconstruction, a total of 19 pelvic landmarks were obtained on each sample, and 11 measurements, including two angles, were calculated.

However, it was not until 2017 that the first intensive and systematic study of this structure type was undertaken, although this study could not determine the precise function of these features. Recent excavations in AlUla have now determined that these structures fulfilled a ritual purpose, with specifically selected elements of both wild and domestic taxa deposited around a betyl.

Extending previous research, we assessed these relations at both the child and classroom levels. We predicted that reactive aggression would relate positively to peer victimization, proactive aggression would relate negatively to peer victimization, and that these relations would vary with classroom levels of aggression.

The goals of the current study were to use a three-reporter methodology and multi-level Latent Profile Analysis: (a) to determine the victim groups that emerge; (b) to evaluate the stability of victim groups over one school year; and (c) to examine differences among victim groups across the adjustment constructs of aggression, depression, anxiety, and negative peer relations. Our sample included 1440 racially/ethnically diverse 4- and 5-grade children (M = 10.15; 50% female).

School-based mental health programs are increasingly recognized as methods by which to improve children's access to evidence-based practices (EBPs), particularly in urban under resourced communities. School-wide positive behavior interventions and supports (PBIS) is one approach to integrating mental health services into school-based programming; however, school providers require training and support to implement programs as intended. We have conducted a randomized controlled trial to compare two models for training school-based personnel to deliver group EBPs to children at high risk of developing internalizing or externalizing problems.

Unfortunately, services provided in schools, and more so in urban schools, have been found to lead to little or no significant clinical improvements. Studies with urban school children seldom report on the effects of clinician training on treatment fidelity and child outcomes.

The goals of this study were to examine how intervention dosage impacts outcomes of KiVa and how teacher factors influence dosage. Participants included 74 teachers and 1409 4th- and 5th-grade students in nine elementary schools.

Many bullying prevention programs take a bystander approach, which encourages children to intervene when they are bystanders to bullying incidents. Little is known about how caregivers' advice to children might promote or undermine the positive bystander behaviors targeted by these programs. Accordingly, the aim of the current study was to investigate relations between caregivers' advice and children's bystander behavior during bullying situations.
