PURPOSE
Sibling aggression has been recognized as a common form of family violence. However, further research is needed to elucidate several antecedents of sibling aggression perpetration and bullying victimization, such as substance use and depressive symptoms. Also, more studies are needed to identify the mediating pathways of depressive symptoms and substance use, which could explain the association between bullying victimization and sibling aggression perpetration as well as the association between sibling aggression victimization and bullying victimization, controlling for exposure to family violence and demographic variables. The current study tested two separate mediational models guided by the displaced aggression theory and self-medication hypothesis.
METHOD
The study used the Bullying, Sexual, and Dating Violence Trajectories From Early to Late Adolescence in the Midwestern United States, 2007-2013 dataset. The original sample consisted of 1162 middle school students who were initially surveyed and followed into three high schools. The first wave was used, which included a sample of 1101 adolescents. Structural equation modeling (SEM) was conducted to first examine whether bullying victimization was associated with sibling aggression perpetration. Then another model was conducted to test whether sibling aggression victimization was associated with bullying victimization.
RESULTS
In the first model, results suggest that bullying victimization is positively associated with sibling aggression. Mediation results indicated depressive symptoms and substance use serially mediated the relationship between bullying victimization and sibling aggression. In the second model, results suggest that sibling aggression victimization is positively associated with bullying victimization. Parallel mediation results indicated that depressive symptoms alone explained the association between sibling aggression victimization and bullying victimization. Finally, serial mediation results indicated that depressive symptoms and substance use serially mediated the association between sibling aggression victimization and bullying victimization.
LIMITATIONS
Limitations include self-report measures and cross-sectional design; therefore, we could not make casual inferences.
CONCLUSION
The implications of these findings suggest the need for continued attention to school-based bully prevention efforts and family interventions. Such efforts could result in a significant reduction in bullying victimization and sibling aggression.

OBJECTIVES
To test associations between 11 caregiver aggressive and non-aggressive discipline behaviours and outcomes (aggression, distraction and prosocial peer relations) of children under 5 years in low-income and middle-income countries (LMICs).
PARTICIPANTS
Data came from the fourth (2009-2013) and fifth (2012-2017) rounds of the UNICEF Multiple Indicator Cluster Surveys. Analyses were restricted to households with children under 5 years, leaving a sample of 229 465 respondents across 60 LMICs. Data were analysed using Bayesian multilevel logistic regression.
RESULTS
Verbal reasoning (80%) and shouting (66%) were the most common parental discipline behaviours towards young children. Psychological and physical aggression were associated with higher child aggression and distraction. Compared with not using verbal reasoning, verbal reasoning was associated with lower odds of aggression (OR)=0.92, 95% credible interval (CI)=0.86 to 0.99) and higher odds of prosocial peer relations (OR=1.30, 95% CI=1.20 to 1.42). Taking away privileges was associated with higher odds of distraction (OR=1.09, 95% CI=1.03 to 1.15) and lower odds of prosocial peer relations (OR=0.92, 95% CI=0.87 to 0.98). Giving the child something else to do was associated with higher odds of distraction (OR=1.06, 95% CI=1.01 to 1.12). The results indicated country-level variation in the associations between parenting behaviours and child socioemotional outcomes.
CONCLUSIONS
Psychological and physical aggression were disadvantageous for children's socioemotional development across countries. Only verbal reasoning was associated with positive child socioemotional development. No form of psychological aggression or physical aggression benefited child socioemotional development in any country. Greater emphasis should be dedicated to reducing parental use of psychological and physical aggression across cultural contexts.

OBJECTIVES
Numerous studies show that a high level of psychopathic traits in youth is related to the propensity to use various types and forms of aggression. The presented study focuses on the relations between psychopathy and aggression, both indirect (relational) and direct in this age group. The triarchic model of psychopathy was used, according to which psychopathy is described as a configuration of boldness, meanness and disinhibition. It was assumed that boldness would be a predictor for indirect aggression and disinhibition - for the direct forms of aggressive behaviors.
METHODS
The sample consisted of 200 older adolescents (108 boys and 92 girls), aged 16-19. Two groups were distinguished for comparison: juveniles from youth fostering centers and youth not violating legal norms. For the measurement of the variables the following self-reports were used: Triarchic Psychopathy Measure, Indirect Aggression Scale (Aggressor Version) and Aggression Questionnaire.
RESULTS
From among the dimensions of psychopathy, the strongest predictor for both forms of aggression (indirect and direct) was disinhibition. The study also revealed the differences in the intensity of psychopathic traits and aggressive behaviors with reference to gender and institutionalization. However, the hypothesis on the relationship between boldness and indirect aggression was not confirmed.
CONCLUSIONS
The results showed that disinhibition and meanness can be considered as significant personality risk factors for aggressive behaviors and violence not only in adults but also in adolescents. The study supported also the heterogeneity of the triarchic model of psychopathy itself.

Understanding how genotypic variation results in phenotypic variation is especially difficult for collective behaviour because group phenotypes arise from complex interactions among group members. A genome-wide association study identified hundreds of genes associated with colony-level variation in honeybee aggression, many of which also showed strong signals of positive selection, but the influence of these 'colony aggression genes' on brain function was unknown. Here we use single-cell (sc) transcriptomics and gene regulatory network (GRN) analyses to test the hypothesis that genetic variation for colony aggression influences individual differences in brain gene expression and/or gene regulation. We compared soldiers, which respond to territorial intrusion with stinging attacks, and foragers, which do not. Colony environment showed stronger influences on soldier-forager differences in brain gene regulation compared with brain gene expression. GRN plasticity was strongly associated with colony aggression, with larger differences in GRN dynamics detected between soldiers and foragers from more aggressive relative to less aggressive colonies. The regulatory dynamics of subnetworks composed of genes associated with colony aggression genes were more strongly correlated with each other across different cell types and brain regions relative to other genes, especially in brain regions involved with olfaction and vision and multimodal sensory integration, which are known to mediate bee aggression. These results show how group genetics can shape a collective phenotype by modulating individual brain gene regulatory network architecture.

Across many species, a major function of vocal communication is to convey formidability, with low voice frequencies traditionally considered the main vehicle for projecting large size and aggression. Vocal loudness is often ignored, yet it might explain some puzzling exceptions to this frequency code. Here we demonstrate, through acoustic analyses of over 3,000 human vocalizations and four perceptual experiments, that vocalizers produce low frequencies when attempting to sound large, but loudness is prioritized for displays of strength and aggression. Our results show that, although being loud is effective for signaling strength and aggression, it poses a physiological trade-off with low frequencies because a loud voice is achieved by elevating pitch and opening the mouth wide into a-like vowels. This may explain why aggressive vocalizations are often high-pitched and why open vowels are considered "large" in sound symbolism despite their high first formant. Callers often compensate by adding vocal harshness (nonlinear vocal phenomena) to undesirably high-pitched loud vocalizations, but a combination of low and loud remains an honest predictor of both perceived and actual physical formidability. The proposed notion of a loudness-frequency trade-off thus adds a new dimension to the widely accepted frequency code and requires a fundamental rethinking of the evolutionary forces shaping the form of acoustic signals.

Aggression elicited by social rejection is costly, prevalent, and often lethal. Attempts to predict rejection-elicited aggression using trait-based data have had little success. This may be because in-the-moment aggression is a complex process influenced by current states of attention, arousal, and affect which are poorly predicted by trait-level characteristics. In a study of young adults (N = 89; 18-25 years), machine learning tested the extent to which nonverbal behavioral indices of attention (eye gaze), arousal (pupillary reactivity), and affect (facial expressions) during a novel social interaction paradigm predicted subsequent aggression towards rejecting and accepting peers. Eye gaze and pupillary reactivity predicted aggressive behavior; predictions were more successful than measures of trait-based aggression and harsh parenting. These preliminary results suggest that nonverbal behavior may elucidate underlying mechanisms of in-the-moment aggression.

Review
The onset of childhood disruptive behaviors is one of the most common presenting difficulties to clinics worldwide. Acceptance and commitment therapy (ACT) has shown to be effective in the reduction of anger and aggression among adults, however to date there has been no systematic review that has examined the effectiveness of ACT in addressing anger and aggression among children, adolescents, and young adults. The current systematic review aimed to evaluate the methodological standing and effectiveness of the peer-reviewed literature of ACT on anger and aggression for this population. PsycINFO, PubMed, and MEDLINE databases were searched systematically in June 2022 to identify studies in English published on the use of ACT for anger and aggression in children, adolescents, and young adults. Seven studies met the inclusion criteria with a combined sample of 305 participants across the interventions. The most common outcome measures used were self-report ratings of anger among participants. Studies were characterized by poor methodological rigor and findings were mixed as regards the effectiveness of ACT in addressing anger and aggression in this population. Some evidence suggests that group ACT may be effective in reducing self-report measures of anger, but no firm conclusions can be drawn from the extant literature due to the heterogeneous nature of the studies, and limited information about ACT protocols and treatment delivery. Further higher-powered studies comparing ACT to treatment as usual or waitlist are needed to clarify what ACT may add as a treatment to anger and aggression in this population.

COVID-19-associated coinfections increase the patient's risk of developing a severe form of the disease and, consequently, the risk of death. The term "flurona" was proposed to describe the coinfection of the influenza virus and SARS-CoV-2. This report is about a case of a 7-month-old female infant who died due to flurona coinfection. A histopathological exam showed activation of microglia (becoming CD45 positive), bronchial inflammation, diffuse alveolar damage in proliferative phase with vasculitis, a peribronchial infiltrate that was predominantly CD20-positive, and a vascular wall infiltrate that was predominantly CD3-positive. The aggressiveness of the two respiratory viruses added up and they caused extensive lung inflammation, which led to respiratory failure, multiple organ failure, and death. Tissues injuries caused by both the influenza virus and SARS-CoV-2 could be observed, without the ability to certify the dominance of the aggression of one of the two viruses.

Despite the increasing interest in exploring microaggression in the humanitarian context, there remains uncertainty on its mechanism for affecting life outcomes. There is a lack of studies on ethnic and racial minorities in non-western countries. The current research explores dimensions and manifestations of microaggression and how they affect wellbeing in a multicultural setting. The study uses a qualitative approach with 15 focus group discussions (FGDs) and 66 participants conducted in 4 provinces of South Africa: Gauteng (k = 6), North-West (k = 3), KwaZulu-Natal (k = 3), and Western Cape (k = 3). The recorded FGDs were transcribed using the intelligent verbatim technique. The transcripts were then analysed using a phenomenological approach. Data analysis was done stepwise using the deductive coding technique. Results show that participants' perception of the dimensions of microaggression varies depending on the manifestation as verbal, behavioural, or systemic. Furthermore, variations in patterns and reactions to dimensions of microaggression were linked with participants' racial identity. It further confirms that experiencing discrimination is associated with poorer wellbeing. Connectedness to the ingroup provides stability and certainty in multi-group societies due to the group rivalry that pervades such societies.

As peer relationships become paramount during early adolescence, there's a normative rise in social anxiety, coinciding with a peak in peer victimization and aggression. Although previous studies have suggested reciprocal associations between changes in social anxiety and adolescent peer victimization and aggression, the mechanics of these associations at the personal trait and time-varying state levels remains unclear. This study examined the longitudinal relations between social anxiety and adolescent peer victimization and aggression by disentangling between-person trait differences from within-person state processes. A total of 4731 Chinese early adolescents (44.9% girls; M age = 10.91 years, SD = 0.72) participated in a four-wave longitudinal study with 6-month intervals. Random-intercept cross-lagged panel model (RI-CLPM) was applied. The results revealed higher levels of social anxiety are associated with more peer victimization and aggression at the between-person trait level. At the within-person state level, adolescent social anxiety, and adolescent physical victimization and physical aggression, reciprocally predicted each other. Relational victimization significantly predicted an increase of social anxiety, but not vice versa. Social anxiety positively predicted relational aggression over time, whereas the effect of relational aggression on social anxiety was only observed at the initial stage of early adolescence. These findings highlight that various types of victimization and aggression might exhibit unique reciprocal associations with social anxiety. Distinguishing between the within-person state and between-person trait effects is crucial in research that informs the co-development of adolescent peer victimization, aggression, and social anxiety.
