The findings on the association between Social Networking Sites and civic engagement are mixed. The present study aims to evaluate a theoretical model linking the informational use of Internet-based social media (specifically, Facebook) with civic competencies and intentions for future civic engagement, taking into account the mediating role of civic discussions with family and friends and sharing the news online. Participants were 114 Italian high school students aged 14–17 years (57 % boys). Path analysis was used to evaluate the proposed theoretical model. Results showed that Facebook informational use was associated with higher levels of adolescent perceived competence for civic action, both directly and through the mediation of civic discussion with parents and friends (offline). Higher levels of civic competencies, then, were associated with a stronger intention to participate in the civic domain in the future. Our findings suggest that Facebook may provide adolescents with additional tools through which they can learn civic activities or develop the skills necessary to participate in the future. © 2015, Society for Community Research and Action.

We collect half-yearly data on nonstop flight frequencies offered by carriers on routes originating from Italian regions to European countries in the period 1998-2010. We find that, as the share of flights belonging to global alliances increases, the number of flights offered by airlines simultaneously expands, especially in the case of full-service carriers. Moreover, there is also evidence that the number of global alliances has a positive impact on flight supply. © 2014. Source

The paper, starting from the analysis of Italian students' difficulties in Maths learnings, presents a quali-quantitative research carried out with some groups of pupils attending the 4th year of the Primary School in Formia (LT), Italy, in the school year 2011/2012. The aim of the research is to verify if the simulation game about the isometries, designed according to a specific theoretic frame and some methodological choices, with particular reference to the transcoding pattern, can: foster and facilitate the learning of geometrical concepts and their retention over time; affect social and scholastic self-efficacy as well as the motivation to learn. The quantitative analysis, carried out with ANOVA, comparing the simulation game to the traditional lesson, shows significant results in the learning for both groups. As far as motivation and social and scholastic self-efficacy are concerned, instead, no meaningful differences have been recorded. The in-depth analysis of the learning and its retention over time carried out through the qualitative analysis has shown the efficacy of the game with regards to both the concepts comprehension and the achievable abstraction levels. © 2014 Springer International Publishing Switzerland.

Civic engagement, defined as involvement in community life, is influenced by reciprocal relationships between individuals and contexts and is a key factor that contributes to positive youth development. The present study evaluates a theoretical model linking perceived democratic school climate with adolescent civic engagement (operationalized as civic responsibility and intentions for future participation), taking into account the mediating role of civic discussions and perceived fairness at school. Participants were 403 adolescents (47.9 % male) ranging in age from 11 to 15 years old (mean age = 13.6). Path analysis results partially validated the proposed theoretical model. Higher levels of democratic school climate were associated with higher levels of adolescent civic responsibility; the association was fully mediated by civic discussions and perceived fairness at school. Adolescents’ civic responsibility, then, was positively associated with a stronger intention to participate in the civic domain in the future. © 2014, Society for Community Research and Action.

Building a theory on extant species, as Ackermann et al. do, is a useful contribution to the field of language evolution. Here, I add another living model that might be of interest: human language ontogeny in the first year of life. A better knowledge of this phase might help in understanding two more topics among the several building blocks of a comprehensive theory of the evolution of spoken language indicated in their conclusion by Ackermann et al., that is, the foundation of the co-evolution of linguistic motor skills with the auditory skills underlying speech perception, and the possible phylogenetic interactions of protospeech production with referential capabilities.
