Online political discourse is increasingly shaped not by a few dominant platforms but by a fragmented ecosystem of social media spaces, each with its own user base, target audience, and algorithmic mediation of discussion. Such fragmentation may fundamentally change how polarization manifests online. In this study, we investigate the characteristics of political discourse and polarization on the emerging social media site Bluesky. We collect all activity on the platform between December 2024 and May 2025 to map out the platform's political topic landscape and detect distinct polarization patterns. Our comprehensive data collection allows us to employ a data-driven methodology for identifying political themes, classifying user stances, and measuring both structural and content-based polarization across key topics raised in English-language discussions. Our analysis reveals that approximately 13% of Bluesky posts engage with political content, with prominent topics including international conflicts, U.S. politics, and socio-technological debates. We find high levels of structural polarization across several salient political topics. However, the most polarized topics are also highly imbalanced in the numbers of users on opposing sides, with the smaller group consisting of only 1-2% of the users. While discussions in Bluesky echo familiar political narratives and polarization trends, the platform exhibits a more politically homogeneous user base than was typical prior to the current wave of platform fragmentation.

This position paper situates AR beauty filters within the broader debate on Body Politics in HCI. We argue that these filters are not neutral tools but technologies of governance that reinforce racialized, gendered, and ableist beauty standards. Through naming conventions, algorithmic bias, and platform governance, they impose aesthetic norms while concealing their influence. To address these challenges, we advocate for transparency-driven interventions and a critical rethinking of algorithmic aesthetics and digital embodiment.

Este trabalho tem como objetivo apresentar uma leitura local, a partir das experiências e vivências no curso de educação popular Pré-Universitário Popular Alternativa, acerca dos primeiros impactos da implementação da Base Nacional Comum Curricular (2018) nos currículos do Ensino Médio (EM). Dessa forma, pretende-se realizar uma apresentação crítica do Novo EM no Rio Grande do Sul e da recepção dele por parte da comunidade escolar, focando na experiência de educação popular. Ademais, o artigo embasa-se em uma metodologia de pesquisa pós-crítica cartográfica (Passos; Barros, 2009), que busca fugir das metanarrativas e construir uma leitura a partir das micropolíticas e microrrelações (Silva, 2010). Nesse sentido, utilizamos um questionário com os educandos do Curso Pré-Universitário Popular Alternativa. O apoio em Freire justifica-se, principalmente, pela conceituação de educação popular, pensada como um elemento da resistência do pensamento crítico frente a retrocessos neoliberais, como as supracitadas reformas na área da educação no Brasil. Quanto à especificidade do ensino de Filosofia, busca-se suporte em Cerletti (2009) por conta de sua noção de autonomia a partir do ensino de Filosofia como resultado de uma pedagogia cuja construção é coletiva.

As new technologies rapidly reshape patterns of political communication, platforms like Twitch are transforming how people consume political information. This entertainment-oriented live streaming platform allows us to observe the impact of technologies such as ``live-streaming'' and ``streaming-chat'' on political communication. Despite its entertainment focus, Twitch hosts a variety of political actors, including politicians and pundits. This study explores Twitch politics by addressing three main questions: 1) Who are the political Twitch streamers? 2) What content is covered in political streams? 3) How do audiences of political streams interact with each other? To identify political streamers, I leveraged the Twitch API and supervised machine-learning techniques, identifying 574 political streamers. I used topic modeling to analyze the content of political streams, revealing seven broad categories of political topics and a unique pattern of communication involving context-specific ``emotes.'' Additionally, I created user-reference networks to examine interaction patterns, finding that a small number of users dominate the communication network. This research contributes to our understanding of how new social media technologies influence political communication, particularly among younger audiences.

The representation of politics in media influences societal perceptions and attitudes. Video games, as a pervasive form of media, contribute significantly to this phenomenon. In this work, we explore political themes within video games by analyzing politically-themed games on game distribution platforms including Steam. We conducted a statistical examination of games with political context to identify patterns and use this as a basis to introduce a first taxonomy to categorize and better understand the interplay between politics and video games. This taxonomy offers a first framework for analyzing political content in games and also sets a foundation for future research in this field.

Politics is the set of activities related to strategic decision-making in groups. Political scientists study the strategic interactions between states, institutions, politicians, and citizens; they seek to understand the causes and consequences of those decisions and interactions. While some decisions might alleviate social problems, others might lead to disasters such as war and conflict. Data visualization approaches have the potential to assist political scientists in their studies by providing visual contexts. However, political researchers' perspectives on data visualization are unclear. This paper examines political scientists' perspectives on visualization and how they apply data visualization in their research. We discovered a growing trend in the use of graphs in political science journals. However, we also found a knowledge gap between the political science and visualization domains, such as effective visualization techniques for tasks and the use of color studied by visualization researchers. To reduce this gap, we survey visualization techniques applicable to the political scientists' research and report the visual analytics systems implemented for and evaluated by political scientists. At the end of this paper, we present an outline of future opportunities, including research topics and methodologies, for multidisciplinary research in political science and data analytics. Through this paper, we expect visualization researchers to get a better grasp of the political science domain, as well as broaden the possibility of future visualization approaches from a multidisciplinary perspective.

Developing tools to automatically detect check-worthy claims in political debates and speeches can greatly help moderators of debates, journalists, and fact-checkers. While previous work on this problem has focused exclusively on the text modality, here we explore the utility of the audio modality as an additional input. We create a new multimodal dataset (text and audio in English) containing 48 hours of speech from past political debates in the USA. We then experimentally demonstrate that, in the case of multiple speakers, adding the audio modality yields sizable improvements over using the text modality alone; moreover, an audio-only model could outperform a text-only one for a single speaker. With the aim to enable future research, we make all our data and code publicly available at https://github.com/petar-iv/audio-checkworthiness-detection.

Instrumental variable (IV) strategies are widely used in political science to establish causal relationships. However, the identifying assumptions required by an IV design are demanding, and it remains challenging for researchers to assess their validity. In this paper, we replicate 67 papers published in three top journals in political science during 2010-2022 and identify several troubling patterns. First, researchers often overestimate the strength of their IVs due to non-i.i.d. errors, such as a clustering structure. Second, the most commonly used t-test for the two-stage-least-squares (2SLS) estimates often severely underestimates uncertainty. Using more robust inferential methods, we find that around 19-30% of the 2SLS estimates in our sample are underpowered. Third, in the majority of the replicated studies, the 2SLS estimates are much larger than the ordinary-least-squares estimates, and their ratio is negatively correlated with the strength of the IVs in studies where the IVs are not experimentally generated, suggesting potential violations of unconfoundedness or the exclusion restriction. To help researchers avoid these pitfalls, we provide a checklist for better practice.

Great socio-economic transitions see the demise of certain industries and the rise of others. The losers of the transition tend to deploy a variety of tactics to obstruct change. We develop a political-economy model of interest group competition and garner evidence of tactics deployed in the global climate movement. From this we deduce a set of strategies for how the climate movement competes against entrenched hydrocarbon interests. Five strategies for overcoming obstructionism emerge: (1) Appeasement, which involves compensating the losers; (2) Co-optation, which seeks to instigate change by working with incumbents; (3) Institutionalism, which involves changes to public institutions to support decarbonization; (4) Antagonism, which creates reputational or litigation costs to inaction; and (5) Countervailance, which makes low-carbon alternatives more competitive. We argue that each strategy addresses the problem of obstructionism through a different lens, reflecting a diversity of actors and theories of change within the climate movement. The choice of which strategy to pursue depends on the institutional context.

Growing literature has shown that NLP systems may encode social biases; however, the political bias of summarization models remains relatively unknown. In this work, we use an entity replacement method to investigate the portrayal of politicians in automatically generated summaries of news articles. We develop an entity-based computational framework to assess the sensitivities of several extractive and abstractive summarizers to the politicians Donald Trump and Joe Biden. We find consistent differences in these summaries upon entity replacement, such as reduced emphasis of Trump's presence in the context of the same article and a more individualistic representation of Trump with respect to the collective US government (i.e., administration). These summary dissimilarities are most prominent when the entity is heavily featured in the source article. Our characterization provides a foundation for future studies of bias in summarization and for normative discussions on the ideal qualities of automatic summaries.

A extensão universitária é um dos pilares da universidade pública e possibilita o desenvolvimento de ações junto à comunidade, estabelecendo o compartilhamento de saberes e práticas do meio acadêmico com o conhecimento popular, visando atender às demandas da população e contribuindo para a transformação da realidade social. No campo da saúde, a extensão deve promover ações que contribuam com o processo crítico e reflexivo sobre os processos de adoecimento e vida. O objetivo deste trabalho é relatar experiências em ações extensionistas realizadas, contando com o protagonismo de bolsista do projeto “Imagens da Vida: arte, saúde, história”, entre março de 2019 a outubro de 2021, evidenciando os desafios enfrentados durante a pandemia. Foram estruturadas duas mostras culturais temáticas em unidade básica de saúde da família em 2019 e, durante a pandemia, houve necessidade de direcionar as ações do projeto para o ambiente virtual, com realização de oficinas, cursos, apresentação de trabalhos em eventos, produção de artigos. Conclui-se que a participação em ações extensionistas constitui um espaço rico de aprendizado para o estudante e possibilita desenvolver o pensamento crítico e reflexivo de problemas observados no território, além de viabilizar a troca de saberes com a comunidade.

Social media has become extremely influential when it comes to policy making in modern societies, especially in the western world, where platforms such as Twitter allow users to follow politicians, thus making citizens more involved in political discussion. In the same vein, politicians use Twitter to express their opinions, debate among others on current topics and promote their political agendas aiming to influence voter behaviour. In this paper, we attempt to analyse tweets of politicians from three European countries and explore the virality of their tweets. Previous studies have shown that tweets conveying negative sentiment are likely to be retweeted more frequently. By utilising state-of-the-art pre-trained language models, we performed sentiment analysis on hundreds of thousands of tweets collected from members of parliament in Greece, Spain and the United Kingdom, including devolved administrations. We achieved this by systematically exploring and analysing the differences between influential and less popular tweets. Our analysis indicates that politicians' negatively charged tweets spread more widely, especially in more recent times, and highlights interesting differences between political parties as well as between politicians and the general population.

A educação é fator primordial na vida do ser humano. Conforme Freire (2013), é humanizadora e conscientizadora. Freire aborda dois tipos de educação: a educação bancária, alicerçada no ensino transmissivo e fragmentário, tendo os educandos como receptores; e a outra, emancipatória, que compreende os educandos como seres ativos e reflexivos. Objetivou-se, neste artigo, refletir sobre as concepções de educação e formação docente. Utilizou-se como metodologia a pesquisa bibliográfica, a partir de Freire (2000, 2005, 2009, 2013), Imbernón (2016), Lopes e Amorim (2018), Scocuglia (2019). Freire defende uma formação permanente para os educadores, tendo em vista que o ser humano é um ser inconcluso, inacabado, necessitando compreender e acompanhar as mudanças que ocorrem na vida, no sistema educacional e nas relações que se estabelecem entre os homens e entre educação e sociedade. Concluímos, portanto, que a formação permanente é imprescindível ao trabalho docente, pois por meio dela o educador torna-se capaz de desenvolver sua prática pedagógica em que estejam presentes o diálogo, a escuta e o respeito aos diferentes saberes como elementos que contribuirão para uma leitura da realidade capaz de transformá-la.

O livro Torto Arado, de Itamar Vieira Junior, é um fenômeno da literatura contemporânea no Brasil. Sua importância está não apenas em uma escrita fluida e interessante, mas também na temática atual a que se dedica. Uma questão social que aparece na narrativa é a construção de uma escola na comunidade de Água Negra e a partir dali duas questões se colocam: Bibiana vê na educação uma possibilidade de alcançar as melhorias necessárias para seu povo e deseja se tornar professora. Por outro lado, Belonísia enxerga na educação formal uma perda de tempo, pois não se enxerga inserida nas atividades escolares guiadas por dona Lourdes, a professora que vem ensinar em Água Negra. As duas formas de enxergar a educação podem ilustrar a importância da teoria freiriana e a necessidade de uma educação inclusiva e libertadora. Para este trabalho, buscou-se encontrar no enredo da obra, ilustrações para a educação bancária e para a educação humanista, conforme a teoria de Freire. Para isso, foram feitos recortes do texto do livro que pudessem ser analogias para a aplicação da teoria em questão. O que se encontra é um retrato da mudança social teorizada por Freire e que se opera na narrativa.

“We are becoming a 24/7 workforce.”—Fair Workweek Initiative“I Can't Breathe”—Eric Garner, George Floyd, Manuel Ellis, Derrick Scott, Byron Williams, Vincente Villela, Ngozi Mbegu, Willie Ray Banks, James Brown…On May 1, 2020, Justa Barrios, a New York City home-care worker and labor activist, passed away from COVID-19. After working twenty-four-hour shifts for fourteen years, Barrios had injuries and compounding medical issues, including asthma, stomach difficulties, and heart problems. Her doctor determined that she could no longer work twenty-four-hour shifts. Yet when the home-care agency received a letter from the doctor requesting Barrios be assigned to eight-hour shifts, the agency dropped her. Barrios fought back. She found her voice in the “Ain't I a Woman?!” Campaign; comrades described her as a “fearless leader.” Stemming from an alliance among female immigrants and US-born garment, plastics, office, and home-care workers, via workers’ centers such as the National Mobilization Against Sweatshops, this organizing effort has sought to end twenty-four-hour days—and the legally permissible practice of paying for only thirteen hours—in New York state through direct action, the courts, union arbitration, and state legislation prohibiting twenty-four -hour shifts. Women such as Justa Barros, Lai Yee Chan, Mei Kum Chu, Seferina Rosario, and Sileni Martinez see the “Aint I a Woman?!” Campaign as a “new women's movement fighting for control over our time, health, respect and payment.” As a cross-racial group, members chose to invoke Sojourner Truth, who tied together the causes of slavery abolition and women's rights, emancipation from coerced labor and from patriarchy, the dignity of women's labor and the dignity of release from work. But this legislation, which would seem so obviously humane and jarringly anachronistic, has been stalled in the New York legislature and ignored by Governor Andrew Cuomo for over a year.

A promoção das ciências biológicas, por meio de mostras científicas, tem se apresentado como uma das principais estratégias pedagógicas utilizadas por escolas brasileiras e estrangeiras. O presente texto tem por objetivo apresentar a metodologia, resultados, discussão e considerações finais sobre a realização do projeto de extensão “Ciências para Todos”, desenvolvido a partir da realização da “I Mostra Científica da Unidade Integrada Francisco Pedro Monroe Conceição”. Optou-se por desenvolver um projeto de extensão no município de Barreirinhas (MA), tendo por público-alvo alunos dos anos finais do ensino fundamental (matutino) da referida escola da rede municipal de ensino. Os resultados se apresentaram de forma quantitativa e qualitativa, sendo provenientes das notas atribuídas para cada turma, grupo e aluno com suas apresentações, bem como participação, desenvolvimento, articulação e desempenho dos discentes durante a preparação e apresentação do evento. A ação de extensão realizada se mostrou pertinente e favorável para a comunidade educacional comtemplada, vez que houve, de forma muito clara, o despertamento do interesse e protagonismo do alunado alvo, haja vista o estabelecimento de vínculos autênticos entre aprendiz e aprendizado durante o procedimento de extensão.

Modern armed conflicts have a tendency to cluster together and spread geographically. However, the geography of most conflicts remains under-studied. To fill this gap, this article presents a new indicator that measures two key geographical properties of subnational political violence: the conflict intensity within a region on the one hand, and the spatial distribution of conflict within a region on the other. We demonstrate the indicator in North and West Africa between 1997 to 2019 to show that it can clarify how conflicts can spread from place to place and how the geography of conflict changes over time.

Twitter has been a focus of research in political science for a few years now as it provides the opportunity to make direct observations on the spread of political information in different communities. Here we will be studying the phenomena of information diffusion, and focus on nodes that are responsible for spreading political information everywhere on the Twitter network. This paper attempts to fill gaps in the literature regarding the demographics of political retweeters using various techniques on the name and location-related data from most active French political retweeters. Here I will try to state the break-down of these accounts in categories based on gender, language, location, education level, and self-descriptions. To put the information about political retweeters in context we will also create a category of non-political retweeters to draw comparisons between the groups regarding the above-mentioned variables.
