Interpersonal aggression is assessed paleoepidemiologically in a large skeletal population from the CA-ALA-329 site located on the southeastern side of San Francisco Bay, California. This comprehensive analysis included all currently recognized skeletal criteria, including craniofacial fracture, projectile injury, forearm fracture, and perimortem bone modification. Craniofacial injury is moderately common, showing an adult prevalence of 9.0% with facial lesions accounting for >50% of involvement. Clinical studies suggest that such separate evaluation of facial involvement provides a useful perspective for understanding patterns of interpersonal aggression. In this group male facial involvement is significantly greater than in females, paralleling the pattern found widely in contemporary populations as well as in African apes. When compared to other North American skeletal samples the prevalence of adult cranial vault injury (3.3%) and especially projectile injury (4.4%) are quite high. However, well documented populations from southern California show markedly higher prevalence for both types of skeletal markers of aggression. Forearm fracture is also assessed using a rigorous radiographic methodology and results suggest that these injuries are not reliable indicators of interpersonal aggression. Lastly, perimortem bone modification was not observed in this population, although it has been recorded from other (older) sites nearby. This study provides an evaluation of multiple skeletal markers of interpersonal aggression in the largest sample from a single site yet reported in North America and, joined with consideration of cultural context, helps further illuminate both geographic and temporal patterns of interpersonal aggression in California.
Introduction: Phubbing is defined as a phenomenon in which individuals use their smartphones during conversations with others, focusing on the smartphones and escaping from interpersonal interactions. This phenomenon has been extensively studied in the literature. However, most studies concerning phubbing have focused on understanding its impact on the receivers; few have investigated the consequences of phubbing on the actors themselves.
Despite an increased risk of committing and experiencing violence among adolescent boys, little is known about either how different types of violence co-occur within individuals or their association with different risk factors. This study used a person-centered approach to (1) identify patterns in boys' perpetration and victimization across a range of 7 types of interpersonal violence (bullying, electronic aggression, sexual harassment/aggression; and psychological/ physical/sexual dating violence); and (2) examine the association of these patterns with 12 risk factors at the individual, relational, and community level to inform future prevention efforts. We used latent class analysis to identify patterns of violence among a diverse sample of 239 adolescent boys from 12 schools in 4 regions of the United States.
Background/aim: Urban violence represents a significant public health issue globally due to its profound impact on daily life and the high prevalence of victims seeking care in health services. This study aims to evaluate sex differences in victimization patterns, using maxillofacial trauma as a marker for urban violence.
Material And Methods: This cross-sectional study analyzed data from medical records of patients treated for traumatic injuries at a referral hospital for traumatology in Belo Horizonte, Brazil, between January 2008 and December 2022.
Introduction: Relational aggression, as a distinct form of aggressive behavior in social relationships, is associated with various physiological and psychological disorders. Although previous research has provided theoretical support for the connection between the Dark Triad (Machiavellianism, psychopathy, and narcissism) and relational aggression, the mediating factors between the two still require in-depth exploration. This study employed a cross-sectional research method to examine the mediating roles of relative deprivation and hostile attribution bias between the Dark Triad and relational aggression.
