As approximately one-third of peer-victimized children evidence heightened aggression (Schwartz, Proctor, & Chien, 2001), it is imperative to identify the circumstances under which victimization and aggression co-develop. The current study explored two potential moderators of victimization-aggression linkages: (a) attentional bias toward cues signaling threat and (b) attentional bais toward cues communicating interpersonal support. Seventy-two fifth- and sixth-grade children (34 boys; M age = 11.67) were eye tracked while watching video clips of bullying. Each scene included a bully, a victim, a reinforcer, and a defender. Children's victimization was measured using peer, parent, and teacher reports. Aggression was measured using peer reports of overt and relational aggression and teacher reports of aggression. Victimization was associated with greater aggression at high levels of attention to the bully. Victimization was also associated with greater aggression at low attention to the defender for boys, but at high attention to the defender for girls. Attention to the victim was negatively correlated with aggression regardless of victimization history. Thus, attentional biases to social cues integral to the bullying context differentiate whether victimization is linked to aggression, necessitating future research on the development of these biases and concurrent trajectories of sociobehavioral development.
A diverse population (429 member) of canola (Brassica napus L.) consisting primarily of winter biotypes was assembled and used in genome-wide association studies. Genotype by sequencing analysis of the population identified and mapped 290,972 high-quality markers ranging from 18.5 to 82.4% missing markers per line and an average of 36.8%. After interpolation, 251,575 high-quality markers remained. After filtering for markers with low minor allele counts (count > 5), we were left with 190,375 markers. The average distance between these markers is 4463 bases with a median of 69 and a range from 1 to 281,248 bases. The heterozygosity among the imputed population ranges from 0.9 to 11.0% with an average of 5.4%. The filtered and imputed dataset was used to determine population structure and kinship, which indicated that the population had minimal structure with the best K value of 2–3. These results also indicated that the majority of the population has substantial sequence from a single population with sub-clusters of, and admixtures with, a very small number of other populations. Analysis of chromosomal linkage disequilibrium decay ranged from ~7 Kb for chromosome A01 to ~68 Kb for chromosome C01. Local linkage decay rates determined for all 500 kb windows with a 10kb sliding step indicated a wide range of linkage disequilibrium decay rates, indicating numerous crossover hotspots within this population, and provide a resource for determining the likely limits of linkage disequilibrium from any given marker in which to identify candidate genes. This population and the resources provided here should serve as helpful tools for investigating genetics in winter canola.
Despite evidence for the effectiveness of cognitive behavioral therapy (CBT) for obsessive-compulsive disorder (OCD), many individuals with OCD lack access to needed behavioral health treatment. Although some literature suggests that virtual modes of treatment for OCD are effective, it remains unclear whether intensive programs like partial hospitalization and intensive outpatient programs (PHP and IOPs) can be delivered effectively over telehealth (TH) and within the context of a global pandemic. Limited extant research suggests that clinicians perceive attenuated treatment response during the pandemic. The trajectory and outcomes of two matched samples were compared using linear mixed modeling: a pre-COVID in-person (IP) sample (
n
= 239) and COVID TH sample (
n
= 239). Findings suggested that both modalities are effective at treating OCD and depressive symptoms, although the pandemic TH group required an additional 2.6 treatment days. The current study provides evidence that PHP and IOP treatment delivered via TH during the COVID-19 pandemic is approximately as effective as pre-pandemic IP treatment and provides promising findings for the future that individuals with complicated OCD who do not have access to IP treatment can still experience significant improvement in symptoms through TH PHP and IOP treatment during and potentially after the pandemic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
