Predictors of Bullying Perpetration and Bullying Victimization Among Semi-Professional Team Sport Players in North Cyprus.

This study explores the influence of individual and relational predictors on bullying perpetration/victimization among semi-professional team sport players in North Cyprus. Three variables reflect on an individual's level characteristics (e.g., gender, age, and nationality), and another one, representing the relational level factor (e.g., negative coaching behavior). The current paper obtained data from athletes through convenient sampling technique and online survey utilization. A total of 190 sports players with an average age of 24.77 (SD = 4.52) participated. All participants were club athletes from 16 diverse nations, competing in four different sports disciplines: football, volleyball, handball, and basketball. Hierarchical regression analysis was implemented to evaluate the above underlying linkages. It was found that age, nationality, and the coach's negative personal rapport significantly predicted bullying victimization dynamics among athletes. Bullying perpetration was only predicted by negative personal rapport with the coach but not by any of the individual level predictors. The moderation analysis showed that negative personal rapport with the coach significantly predicted the level of bullying victimization, the age and the nationality of the athlete moderated the relationship between the negative personal rapport and bullying victimization. In other words, the negative personal rapport had a higher effect on bullying victimization for the younger athletes and for international ones. Such findings have the potential to shape the base for further ongoing works, which could underline the critical demand for more emphasis and analysis of nationality, gender, age, and coach's negative rapport on bullying perpetration or victimization. The significance of the study's findings, its limits, and potential paths for further interpersonal violence research are addressed.

Coping with Public and Private Face-to-Face and Cyber Victimization among Adolescents in Six Countries: Roles of Severity and Country.

This study investigated the role of medium (face-to-face, cyber) and publicity (public, private) in adolescents' perceptions of severity and coping strategies (i.e., avoidant, ignoring, helplessness, social support seeking, retaliation) for victimization, while accounting for gender and cultural values. There were 3432 adolescents (ages 11-15, 49% girls) in this study; they were from China, Cyprus, the Czech Republic, India, Japan, and the United States. Adolescents completed questionnaires on individualism and collectivism, and ratings of coping strategies and severity for public face-to-face victimization, private face-to-face victimization, public cyber victimization, and private cyber victimization. Findings revealed similarities in adolescents' coping strategies based on perceptions of severity, publicity, and medium for some coping strategies (i.e., social support seeking, retaliation) but differential associations for other coping strategies (i.e., avoidance, helplessness, ignoring). The results of this study are important for prevention and intervention efforts because they underscore the importance of teaching effective coping strategies to adolescents, and to consider how perceptions of severity, publicity, and medium might influence the implementation of these coping strategies.

Longitudinal Associations among Machiavellianism, Popularity Goals, and Adolescents' Cyberbullying Involvement: The Role of Gender.

Drawing on the social-ecological perspective, this longitudinal study investigated the potential moderating effect of gender in the relationships among Machiavellianism, popularity goals, and cyberbullying involvement (i.e. victimization, perpetration) among adolescents from China, Cyprus, India, and the United States. There were 2,452 adolescents (Mage = 14.85; SD = .53; 13-16 years old; 49.1% girls) from China, Cyprus, India, and the United States included in this study. They completed surveys on Machiavellianism, popularity goals, and cyberbullying victimization and perpetration during the fall of 2014 (Time 1). One year later, during the fall of 2015, adolescents completed surveys on cyberbullying victimization and perpetration. Findings revealed that Machiavellianism and popularity goals were both associated positively with Time 2 cyberbullying victimization and perpetration for all adolescents. The associations between Machiavellianism and Time 2 cyberbullying perpetration and between popularity goals and Time 2 cyberbullying perpetration were stronger for Chinese and Indian boys than girls. Opposite patterns were found for popularity goals and Time 2 cyberbullying perpetration for adolescents from the United States. Gender did not moderate any of the associations for Cypriot adolescents or for Time 2 cyberbullying victimization. The social-ecological perspective provides a useful understanding of how various contexts influence bullying.

Retrosternal Deformations after Coronary Artery Bypass Surgery Using Statistical Shape Analysis

Abstract Introduction: In this study, we aimed to evaluate the anatomical deformations of the major vascular structures in the retrosternal area caused by adhesions following coronary artery bypass grafting (CABG). Methods: This single-center, retrospective study included a total of 40 patients with a previous CABG who were admitted to our emergency unit for any reason and underwent a contrast-enhanced chest computed tomography (patient group) and 40 patients without previous cardiac surgery (control group) between January 2018 and November 2019. The retrosternal area was compared between the groups using the statistical shape analysis method. The distance between the sternum and the ascending aorta and pulmonary artery was measured and anatomical deformations of the retrosternal area were examined. Results: There was a statistically significant difference in the anatomical structures of the retrosternal area between the patient and control groups (P<0.001). The distance from the midsternal line to the highest point of the pulmonary artery was statistically significantly shorter in the patient group, compared to the control group (P=0.013). The distance from the sternum to the ascending aorta was also shorter in the patient group, although it did not reach statistical significance (P>0.05). Conclusions: Our study results showed narrowing of the retrosternal area following CABG and a shorter distance from the sternum to the pulmonary artery than the ascending aorta. Based on these findings, surgeons should be cautious about possible injuries in patients requiring cardiac surgery with repeated median sternotomy.
