The study was conducted by researchers from the University of Quebec at Montreal, Laval University, the University of Alabama, the University of Montreal, and University College Dublin.
"Aggressive behavior in middle childhood is at least partly explained by genetic factors, but genetic influences on behavior usually don't operate independently of environmental influences," notes Mara Brendgen, professor of psychology at the University of Quebec at Montreal, who led the study.
Researchers studied 217 Canadian identical and fraternal twin pairs at age 7 to delve into the interplay between nature and nurture involving the source of aggression in the children. Twin pairs weren't in the same classrooms, but had different teachers and different classmates. Classmates rated the twins' level of aggressive behavior and the extent to which they were victimized by peers. The twins' teachers rated the quality of their relationship with each twin. Genetic effects on aggression were estimated by comparing the similarity in behaviors of identical and fraternal twin pairs.
The study found that children who were genetically vulnerable to being aggressive were more likely to be victimized by their classmates than others. However, these children were protected from acting aggressively and being the target of other children's aggression if they had a very good relationship with their teacher—a relationship that was warm and affectionate and involved open communication.
"Children's relationships with teachers and with peers in school play a critical role in shaping their social-behavioral development," notes Brendgen. "Our study found that a good relationship with the teacher can protect genetically vulnerable children from being aggressive and, in consequence, from becoming the target of other children's aggressive behavior."
The findings can inform interventions aimed at addressing children's aggression, and can also be used in teacher-training efforts.
The study was supported by the Social Sciences and Humanities Research Council of Canada, the Fonds Concerté pour l'Aide à la Recherche, the Fonds Québécois de la Recherche sur la Société et la Culture, the Canadian Institutes of Health Research, and the Fonds de Recherche en Santé du Québec.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
