The presence of cyberspace in the lives of young people is such that we can no longer distinguish between online and offline spheres. They live a process of onlife development that is not always equitable in terms of gender. This paper aims to account for the online behaviour of Spanish adolescents according to gender and age, the decisions they make when constructing their virtual identity, and the effects that this has on them. A quantitative study has been carried out at a national level (N=2,076, 12-18 years old) following a non-experimental ex post facto design by means of a survey study. The results show that there are gender differences in the preference for one or other social network. A high percentage of girls make different choices when it comes to their online presence. Unlike boys, girls state that their virtual self and their behaviour significantly influence the opinion that they have of themselves and their need to feel integrated. In conclusion, the decisions that adolescents make when creating their virtual selves do not only have negative consequences derived from poor management, but are also plagued by mandates and stereotypes that determine how they should be and what they should do online; something that is especially pressing for girls.

Despite recent efforts to examine the political outcomes of social media use, little is known about the reinforcement of political empowerment and moderating effect of political interest. It is vital to understand the elements that influence the level of political empowerment. Therefore, this paper used a sample of Pakistani voters (n=410) aged 18-29 to offer insight into how social media use alongside other political behaviors, such as partisanship, political expression, and political interest, affect political empowerment. Social Identity Theory (SIT) and rational choice theory provided the theoretical underpinning for the variables of this study. The statistical analyses were performed using Partial Least Squares (PLS) to assess the effects of four variables i.e., social media use, political partisanship, political expression, and political interest, on political empowerment. This study made a significant contribution to the research literature by combining SIT and rational choice theory in one framework. This study also expands the literature on political interest by introducing political interest as a moderator between the inconsistent relationship of political expression and political empowerment. Our results demonstrated that partisanship and social media use positively influenced political expression among young voters. Moreover, political interest positively moderated the relationship between political expression and political empowerment. [ABSTRACT FROM AUTHOR]

Social media have established a new way of communicating and understanding social relationships. At the same time, there are downsides, especially, their use of algorithms that have been built and developed under their umbrella and their potential to alter public opinion. This paper tries to analyse the YouTube recommendation system from the perspectives of reverse engineering and semantic mining. The first result is that, contrary to expectations, the issues do not tend to be extreme from the point of view of polarisation in all cases. Next, and through the study of the selected themes, the results do not offer a clear answer to the proposed hypotheses, since, as has been shown in similar works, the factors that shape the recommendation system are very diverse. In fact, results show that polarising content does not behave in the same way for all the topics analysed, which may indicate the existence of moderators –or corporate actions– that alter the relationship between the variables. Another contribution is the confirmation that we are dealing with non-linear, but potentially systematic, processes. Nevertheless, the present work opens the door to further academic research on the topic to clarify the unknowns about the role of these algorithms in our societies. [ABSTRACT FROM AUTHOR]

In 2019 the climate movement experienced an unprecedented growth in its mobilization capacity and its political and media impact. This success is closely linked to the rise of Greta Thunberg and her global impact, as well as to the organization effort of "Fridays for Future" in hundreds of local groups around the globe. This paper studies the connection between these two elements based on the movement frame analysis and its dissemination on social media. Through an analysis of the activists' speeches and social media messages, Greta's key role in the establishment and evolution of a new frame for the climate movement can be seen. This is reinforced and legitimized with her own personal story told through the hero's journey or monomyth. Then, the inclusion and adaptation of Greta's frame in the local group of "Fridays for Future" in Barcelona based on the content analysis of its publications on Twitter and Instagram will be analyzed. The results show how, despite the reluctance regarding personified leadership, Greta's frame has a significant influence on the discourse of the local movement and on the "Fridays for Future" Barcelona's social media followers. The analysis also provides empirical evidence of the relevance of glocal dynamics in online social movements. [ABSTRACT FROM AUTHOR]
