Bullying has serious long term consequences for all concerned. The cost of ignoring bullying is great, and it is no longer acceptable to view bullying as a normal part of everyday life that children have to learn to tolerate. Effective strategies exist to reduce the frequency of bullying and to make this type of aggressive behaviour less likely to occur.

The aim of this study was to examine stability and change in genetic and environmental influences on reactive (impulsive and affective) and proactive (planned and instrumental) aggression from childhood to early adolescence. The sample was drawn from an ongoing longitudinal twin study of risk factors for antisocial behavior at the University of Southern California (USC). The twins were measured...

There is no doubt, that the medical staff has often to face aggressive patients, their threats and event their violent physical attacks today. More frequently than ever they are faced with the necessity to think over and consider very carefully the way to defend against imminent or persistent attack on them. First, I would attempt to qualify patients' aggressive behaviour - from lesser acts, wh...

In recent years, there has been increasing interest in indirect aggression as the most common aggressive behaviour in adulthood. Despite this interest, there are not a great many instruments for measuring this behaviour in adults. The aim of our study was to develop the Spanish adaptation of one of the few instruments that does exist: the Indirect Aggression Scale, in its aggressor and target v...

We found an inverse relation between physical aggression by patients and physician staffing--when more physicians were available, physical aggression decreased. Episodes of nonphysical aggression increased with higher levels of psychiatrist staffing, but were not related to general physician staffing.

All animals interact with conspecifics during their life, and nearly all also display some form of aggression. An enduring challenge, however, is to understand how the experiences of an individual animal influence its later behaviours. Several studies have shown that prior winning experience increases the probability of initiating fights in later encounters. Using behavioural assays in the labo...

Giant Cell Tumour (GCT) of the distal fibula is extremely rare and poses challenges in the surgical management. Wide excision or intralesional curettage, along with adjuvant chemical cauterisation can prevent the recurrence of GCT. The excised bone gap needs reconstruction using tricortical iliac autograft and supportive plate fixation. In addition to wide excision, preservation of ankle mortis...

Flexible barrier films preventing permeation of gases and moistures are important for many industries ranging from food to medical and from chemical to electronic. From this perspective, graphene has recently attracted particular interest because its defect-free monolayers are impermeable to all atoms and molecules. However, it has been proved to be challenging to develop large-area defectless ...

The relative contributions to sexual aggression of general sexual and aggressive motives and their respective inhibitory factors were compared. One hundred forty-three university males responded to self-report measures of sexual and aggressive drives, sex and hostility guilt, social desirability response bias, and history of coercive sexuality. With the effects of social desirability controlled...

Wolbachia bacteria are endosymbionts that infect approximately 40% of all insect species and are best known for their ability to manipulate host reproductive systems. Though the effect Wolbachia infection has on somatic tissues is less well understood, when present in cells of the adult Drosophila melanogaster brain, Wolbachia exerts an influence over behaviors related to olfaction. Here, we sh...
