Towards Cyberbullying Detection: Building, Benchmarking and Longitudinal Analysis of Aggressiveness and Conflicts/Attacks Datasets from Twitter

Publication . Ferreira, Paula; Salgado Pereira, Nádia; Rosa, Hugo; Oliveira, Sofia; Coheur, Luísa; Francisco, Sofia; Souza, Sidclay B.; Ribeiro, Ricardo; Carvalho, João P.; Paulino, Paula; Trancoso, Isabel; Veiga Simão, Ana

Offense and hate speech are a source of online conflicts which have become common in social media and, as such, their study is a growing topic of research in machine learning and natural language processing. This article presents two Portuguese language offense-related datasets that deepen the study of the subject: an Aggressiveness dataset and a Conflicts/Attacks dataset. While the former is similar to other offense detection related datasets, the latter constitutes a novelty due to the use of the history of the interaction between users. Several studies were carried out to construct and analyze the data in the datasets. The first study included gathering expressions of verbal aggression witnessed by adolescents to guide data extraction for the datasets. The second study included extracting data from Twitter (in Portuguese) that matched the most frequent expressions/words/sentences that were identified in the previous study. The third study consisted in the development of the Aggressiveness dataset, the Conflicts/Attacks dataset, and classification models. In our fourth study, we proposed to examine whether online aggression and conflicts/attacks revealed any trend changes over time with a sample of 86 adolescents. With this study, we also proposed to investigate whether the amount of tweets sent over a period of 273 days was related to online aggression and conflicts/attacks. Lastly, we analyzed the percentage of participants who participated in the aggressions and/or attacks/conflicts.

A comparative analysis of adolescents' emotions and emotion regulation strategies when witnessing different cyberbullying scenarios

Publication . Gomes, Sónia da Silva; Ferreira, Paula; Salgado Pereira, Nádia; Veiga Simão, Ana

The search for greater popularity and acceptance by peers increases the use of social networks that may cause cyberbullying. The high number of adolescents who observe this phenomenon may help reduce the negative impact on the victims. Emotion regulation is an important predictor of adolescents’ psychological adjustment and social competence to adopt a prosocial behavior. Bystanders of these incidents may misinterpret what they see, due to specific cyberbullying characteristics which may influence emotion regulation negatively. Studies about emotions and emotion regulations in bystanders are scarce. Therefore, this study aims to investigate the emotional reactions and emotional regulation strategies of bystanders while witnessing various cyberbullying scenarios (posting photographs, direct threats, offences to integrity, threats to share personal information), as well as to focus on different behavior, victim characteristics, aggressor traits, and spectator reactions. A convenience sample of 143 adolescents (from 12 to 17 years old) was used. Results showed that worry and sadness were the most expressed emotions in all sce narios (mainly for girls) and posting a photograph was considered more concerning for girls and boys both. To regulate emotions, participants used distraction (especially seven graders) and rumination strategies. Nonetheless, when posting a photo without permission, they all adopted prosocial behavior (boys and girls) because they considered it more serious. Seventh graders adopted less prosocial behavior than eighth graders. In short, girls were more prosocial than boys. Boys may have more difficulty in regulating emotions properly and it may contribute to not intervening. Also, younger adolescents may have experienced less emotional maturity. Therefore, developing programs based on socio-emotional skills, which increase awareness of the seriousness of cyberbullying, can teach youth how to deal with emotions in order to regulate them effectively, thus increasing emotional maturity.

Fostering self-regulated learning in preschool through dynamic assessment methodologies

Publication . Silva Moreira, Janete; Ferreira, Paula; Veiga Simão, Ana

Self-regulated learning is a transversal competency which plays a central role in acquiring autonomy. This investigation aimed to support approaches that foster self-regulated learning in preschool. We proposed to improve preschoolers’ self-regulated learning strategies (i.e., forethought, performance, and self-reflection) through the educational intervention Pipo and Mia, the magic knights, hypothesizing different results when comparing levels of the program intervention. Participants included 115 preschoolers and their nine teachers. Teachers implemented the program to children, and engaged in professional training simultaneously. Aiming to validate the Dynamic Assessment of Self-regulation in Preschool (DASP) method socially, it was used as children’s pre and post-measure, and focus groups were conducted with teachers to assess its validity. Results showed improvements in children’s use of strategies, and some significant differences between intervention levels. Teachers highlighted the DASP method potentialities. The study’s contributions and constraints are discussed considering implications for practice, research, theory, and policy.

Condom use across casual and committed relationships: The role of relationship characteristics

Publication . Godinho, Cristina Albuquerque; Pereira, Cicero Roberto; Pegado, Ana; LUZ, RITA; Alvarez, Maria-João

Background: While the existence of a complex variety of casual sexual relationships (CSRs) has been acknowledged, studies rarely describe the prevalence of condom use across these relationships or how their hybrid nature, specifically relationship characteristics, affect condom use. This study aims to describe condom use within committed relationships and various types of casual sexual relationships (CSRs), examining the influence of relationship characteristics on condom use among culturally validated relationship types (committed, friends with benefits, hookups, booty call). Methods: Emerging adults (N = 728, 18–29 years, M = 22.56; SD = 3.01) completed a survey with four blocks: sociodemographics; brief sexual history; relationships over the previous year; and current relationship, assessing relationship type, ten relationship characteristics (e.g., commitment, emotional and sexual exclusivity, partner acquaintance, sexual involvement) and condom use (vaginal, oral, and anal), operationalized by three measures (use at last encounter, likert-type scale and percentage of use). Results: The results showed patterns in condom use by relationship type and illuminated how relationship characteristics—grouped into three factors: commitment, intimacy, and sexuality—mediate condom use. Condom use was more frequent in vaginal than anal and oral sex, and less frequent in committed relationships. No significant differences were found in condom use in vaginal sex between committed relationships and hookups, with condom in these relationships being significantly lower than in booty call. Intimacy mediated between all contrasts tested and condom use in vaginal sex, while sexuality mediated between committed vs. CSRs and condom use in anal and oral sex. Conclusions: Findings point to the need of considering the diversity of CSRs for understanding condom use and highlight the role of intimacy as a relevant mechanism associated with condom use in vaginal sex and of sexuality in oral and anal sex, which should be taken into consideration in the tailoring of health promoting efforts.
