The purpose of this study was to understand how adolescent cybervictims perceive their school climate and whether telling school community members, such as teachers, play a significant role in these perceptions. Another objective was to understand whether age and gender played a significant role in the relation between whom cybervictims told and their perceived school climate. The Cybervictims Scale for Adolescents and Children and the Perceived School Climate Scale were applied to 3525 Portuguese students of whom 218 were cybervictims attending 6th, 8th, and 11th grades. Results showed that even though adolescent cybervictims reported cybervictimization more to friends and parents, those who told teachers about their experience, tended to report more positive perceptions of their school climate. Gender and age did not play a significant role in the relationship between cybervictimization and perceived school climate. Implications of the findings are discussed with regards to the role of teachers and in‐service training in preventing cyberbullying.

SummaryWe report the application of single-stranded conformation polymorphism (SSCP) analysis to the screening of 15 functionally important Protein S (PS) gene (PSα) regions (4.243 Kb) in 6 unrelated families with PS deficiencies. Direct sequencing of the fragments with altered migration patterns led to the identification of the corresponding molecular alterations. A missense mutation, G to T transversion at codon Cys598, and two different alterations, leading either to allelic exclusion, or premature termination of the protein translation: a G to A transition at codon Trp465 and a 1 nt (T) insertion at codon 265, were identified. The 1 nt insertion was observed in three apparently unrelated families but with a common geographical origin and the mutated allele was undetectable in platelet mRNAs of affected individuals. Family analysis confirmed, in each case, a perfect cosegregation of the mutation with the PS deficiency. We conclude that these alterations represent the causative mutations.

This study aims to clarify how the quality of the family environment is related to the involvement in cyberbullying behaviors, either as a cyber-victim or as a cyber-aggressor, via a cross-sectional research design. With this purpose a diagnostic questionnaire with questions about both the quality of family environment and cyberbullying was conceived and administered to 3525 adolescents attending 6th, 8th and 11th grades at several schools in Portugal. The results suggested that two family aspects seem to be equally important in protection against cyberbullying: perception of family support and perception of rules within the family. A hierarchical regression analysis reveals that lack of family support is more predictive of cyber-victimization and that a lack of family rules is more predictive of cyber-aggression. The authors discuss the implications for the well-being of adolescents, as well as the challenges that parents face in the supervision of adolescents' use of digital technologies.
