Findings: The nursing staff's knowledge increased significantly after the educational intervention.

Children's intervention strategies in situations of victimization by bullying: social cognitions of outsiders versus defenders.

This study examined the social cognitions of outsiders and defenders about intervening in situations of victimization by bullying. Do outsiders and defenders behave differently in victimization situations because of differences in competence beliefs, or because of a selectivity effect in intervening? These issues were examined in a sample of 102 outsiders and 107 defenders who were classified into these bullying roles through a peer-nomination procedure out of a total sample of 761 10- to 14-year-old Dutch children. These children were presented with imaginary victimization events.

Longitudinal Changes of Aerobic Fitness in Youth Ages 12 to 23.

In the Amsterdam Growth and Health Study, 103 girls and 97 boys were studied five times on a longitudinal basis over a period of 8 years, covering the teenage years from 12 to 17 until young adulthood at 22/23 years. Measured were anthropometric variables such as height, weight (BW), and body fat, and physiological variables such as maximal aerobic power (V̇Omax) and endurance performance (max slope). During the teenage period, V̇Omax/BW remains constant in boys and decreases in girls whereas endurance performance increases in boys and remains constant in girls.
