Summary
Bullying roles like perpetrators and victims are generally stable in children aged 11-17. However, the bully/victim role is unstable, with frequent shifts, and physical bullying decreases over time.
Area of Science:
- Child Psychology
- Developmental Psychology
- Adolescent Behavior
Background:
- Bullying is a significant issue in schools with various roles.
- Understanding the stability and change in these roles is crucial for intervention.
Purpose of the Study:
- To examine the stability and developmental changes in bullying roles among school students.
- To identify distinct trajectories for perpetrators, victims, and bully/victims.
Main Methods:
- Longitudinal prospective study of 916 students from age 11 to 17.
- Data collected biannually to track changes in bullying roles.
Main Results:
- Perpetrator and victim roles showed relative stability.
- The bully/victim role was the most unstable, with frequent transitions.
- Physical bullying decreased over time for bullies and victims, but remained high for bully/victims.
Conclusions:
- Bullying roles exhibit varying degrees of stability and change throughout adolescence.
- Findings support targeted interventions for different bullying roles, especially the unstable bully/victim category.
- Early detection and tailored strategies can be informed by these developmental trajectories.

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

02:31Phase Transitions
23.2K
Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

01:58Cooperative Allosteric Transitions
8.7K
Cooperative allosteric transitions can occur in multimeric proteins, where each subunit of the protein has its own ligand-binding site. When a ligand binds to any of these subunits, it triggers a conformational change that affects the binding sites in the other subunits; this can change the affinity of the other sites for their respective ligands. The ability of the protein to change the shape of its binding site is attributed to the presence of a mix of flexible and stable segments in the...

Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...
