Este paper analisa o papel dessas elites no contexto brasileiro, tomando como estudo de caso o X (Twitter) no período entre as eleições de 2022 e os eventos de 8 de janeiro de 2023. A partir de uma abordagem mista, que combina indicadores estatísticos (Índice de Gini, Regra de Pareto e análise bivariada) e interpretação qualitativa de clusters narrativos, identificou-se uma forte assimetria de visibilidade: 32 perfis concentraram 80% dos retweets e 31 perfis, 80 % das curtidas. Essa desigualdade estrutural, típica de redes de escala livre, reflete o papel das affordances algorítmicas na conversão de emoção em visibilidade. Argumenta-se que a radicalização digital opera como um processo identitário e performativo, sustentado pela interação entre estrutura técnica, narrativas simbólicas e afetos. As plataformas, portanto, não são meios neutros, mas atores mediadores que moldam a esfera pública contemporânea ao transformar a emoção política em valor algorítmico e capital de atenção.; The rise of digital elites—a restricted group of highly central profiles with exceptional capacity to circulate content—has redefined visibility and engagement dynamics on online platforms, with direct implications for political polarization and radicalization. This paper examines the role of these elites in the Brazilian context, focusing on X (Twitter) between the 2022 elections and the events of January 8, 2023. Adopting a mixed-methods approach, which combines statistical indicators (Gini Index, Pareto Principle, and bivariate analysis) with a qualitative interpretation of narrative clusters, the study identifies a sharp asymmetry of visibility: 32 profiles accounted for 80% of all retweets and 31 for 80% of all likes. This structural inequality, typical of scale-free networks, reflects the role of algorithmic affordances in converting emotion into visibility. The findings suggest that digital radicalization operates as an identitarian and performative process, sustained by the interaction among technical structures, symbolic narratives, and affective dynamics. Platforms, therefore, are not neutral media but active mediators that shape the contemporary public sphere by transforming political emotion into algorithmic value and attention capital.

P. Editor: Gaspar, Pedro Miguel; Facal, David; Navarro-Pardo, Esperanza; Ramadani, Veland Resumo: Work plays a significant role in people’s lives by providing access to economic resources, interpersonal connections, as well as the achievement of goals and recognition. Work helps structure daily life, that’s why a change in this relationship, such as the transition to retirement, is likely to have impacts on people’s lives. There are different impacts that may arise from retirement, including on informal social support networks. Based on a qualitative methodology, carried out through 22 biographical interviews with retired individuals, the aim of this research was to capture the impacts of retirement on family relationships. Regarding interaction with the spouse, three types of impacts were identified (positive, adaptive and negative), while in relationships with other family members it was possible to understand the dynamics of reciprocity in terms of the provided and received support by the interviewees.

P. Editor: Gaspar, Pedro Miguel; Facal, David; Navarro-Pardo, Esperanza; Ramadani, Veland Resumo: Retirement represents a significant change in individuals’ lives, which is why it can be prepared through an educational/training process. However, the scientific literature points to a lack of practices in this preparation. Based on a qualitative methodology, conducted through interviews with workers, retirees or pre-retirees, perceptions about retirement and the factors influencing the development of retirement planning programs were captured. It was found two meanings attributed to retirement and three factors that restrict the development of retirement preparation in organizations. Considering that none of the interviewees took part in retirement planning processes, this research presents guidelines that may help implement this practice in organizations.
