OBJECTIVE Using nationally representative data, this study examined the prevalence of very frequent physical fighting (≥12 times per year) among youth in 27 countries and cities. Frequent physical fighting has rarely been reported in the previous literature despite the implications for research and practice. METHODS Analyses were based on the Global School-based Student Health Survey (2003-20...

To develop mathematical critical thinking skills, students are expected to have a fighting attitude in solving problems. This can support learning that is oriented towards students' skills. The purpose of this research analyze the trend studying skills uses systematic literature review method which carried out by identifying, assessing, and interpreting all available evidence indicators how bri...

Play fighting is common in juvenile mammals as a peri-pubertal form of agonistic behavior preceding adult aggressive behavior. In golden hamsters, play fighting peaks in early puberty around postnatal day 35 (P-35), and gradually matures into adult aggression in late puberty. Though extensively studied, the neural mechanisms underlying play fighting remains poorly understood. My dissertation fo...

Accurate assessment of competitive ability is a critical component of contest behavior in animals, and it could be just as important in human competition, particularly in human ancestral populations. Here, we tested the role that facial perception plays in this assessment by investigating the association between both perceived aggressiveness and perceived fighting ability in fighters' faces and...

The aim of the study was to assess interdependence of specific motor abilities (situation karate tests) and motor skills (karate techniques), and karate performance (fighting efficiency) in under-sixteen male karateka aged 11-12 and 13-14 years. A battery of 5 situation motor tests were applied and 6 basic elements of karate technique evaluated in a sample of 20 male karateka aged 11-12 and 20 ...

Then aims of the current study were 1) to provide cross-national estimates of the prevalence of physical fighting and weapon carrying among adolescents aged 11-15 years; (2) To examine the possible effects of physical fighting and weapon carrying on the occurrence of physical (medically treated injuries) and emotional health outcomes (multiple health complaints) among adolescents within the the...

Single unit activity was recorded extracellularly from the midbrain of rats during fighting behavior and during non-fighting control manipulations. Fighting behavior was elicited by footshock or startle stimuli or occurred spontaneously as a result of prior footshock presentations. Seven cells were found in the midbrain reticular formation and central gray which displayed maximum firing rates d...

The use of Information and Communication Technologies (ICT) in educating children with Autism Spectrum Disorder (ASD) is a dynamic field linking both special education and learning technologies research areas. This paper reports on the design and development of Pre-Vocational Skills Laboratory, a Web-based learning environment aiming to support students with ASD towards developing pre-vocationa...

OBJECTIVES We sought to (1) compare estimates of the prevalence of fighting and weapon carrying among adolescent boys and girls in North American and European countries and (2) assess in adolescents from a subgroup of these countries comparative rates of weapon carrying and characteristics of fighting and injury outcomes, with a determination of the association between these indicators of viole...
