Technologically mediated contexts are social arenas in which adolescents can be both perpetrators and victims of aggression. Yet, there remains little understanding of the developmental etiology of cyber aggression, itself, as experienced by either perpetrators or victims. The current study examines 3-year latent within-person trajectories of known correlates of cyber-aggression: problem behavior, (low) self-esteem, and depressed mood, in a large and diverse sample of youth (N = 1,364; 54.6 % female; 12–14 years old at T1). Findings demonstrate that developmental increases in problem behavior across grades 8–10 predict both cyber-perpetration and victimization in grade 11. Developmental decreases in self-esteem also predicted both grade 11 perpetration and victimization. Finally, early depressed mood predicted both perpetration and victimization later on, regardless of developmental change in depressed mood in the interim. Our results reveal a clear link between risky developmental trajectories across the early high school years and later cyber-aggression and imply that mitigating trajectories of risk early on may lead to decreases in cyber-aggression at a later date. 相似文献

This paper documents the lessons drawn from several years of practical work with a range of Programme and Project Cycle Management (PPCM) processes and tools. The need for PPCM training, and not simply Logical Framework training, is emphasised, as is the importance of using an experiential training methodology. Institutional ownership of both PPCM tools and approaches are considered to be vital for success. Since so many donors now use PPCM tools, the need for development professionals to have PPCM skills and knowledge is paramount. The value of logframes as a tool to both increase programme/project ownership and communication is highlighted. The importance of thinking outside the boxes of the logframe at the project/programme review stage is also emphasised. 相似文献

The developmental-ecological perspective provides a means for understanding how the oppression of children occurs within multiple
social contexts that interrelate to produce harmful outcomes for children. Because children lack power due to their age, size,
and lack of resources, they are easy targets for adult oppression. Children are exposed to different levels and types of oppression
that vary depending on their age, level of development, socioeconomic class, race, and the beliefs and perceptions of their
parents. According to the theory of differential oppression, oppression leads to adaptive reactions by children: passive acceptance,
exercise of illegitimate coercive power, manipulation of one's peers, and retaliation. Reducing the oppressive acts of adults
and alleviating the damaging circumstances that characterize the social environment of children is critical to reducing the
prevalence of juvenile delinquency and other problem behaviors.
