Title: Ecopistas e a Valorização do Patrimônio Ferroviário. Contribuições ao Ramal de Mora (distrito de Évora) Authors: Rocha, Beatriz Alves Goulart; Kühl, Beatriz Mugayar; cardoso de Matos, Ana; Lourencetti, Fernanda de Lima Abstract: Este trabalho parte de uma pesquisa de doutorado em desenvolvimento e, mais especificamente, de um estágio de pesquisa no exterior decorrente dela, na qual a reutilização das antigas estruturas ferroviárias tem sido discutida, analisando, principalmente a relação entre os novos usos adotados e as demandas de cada localidade, além das intervenções arquitetônicas realizadas para essa finalidade. Neste sentido, compreendendo a relação da reutilização do patrimônio com a sua preservação e, mais indiretamente com a sustentabilidade, o texto tem como objetivo demonstrar, a partir de um caso em Beirã, uma vila portuguesa, a diversidade de usos adotados em um antigo conjunto ferroviário, preservando o ambiente construído, sem intervenções descaracterizantes. Trata-se de uma pesquisa de abordagem qualitativa, que utiliza como métodos: a revisão bibliográfica - durante todo o processo de pesquisa – e, principalmente, a visita de campo, que dão origem à descrição do caso estudado. Pretende-se, com isso, que o trabalho direcione um olhar crítico sobre as intervenções no ambiente construído, especialmente no patrimônio ferroviário, associadas aos novos usos adotados. Ademais, espera-se que, por meio da comparação, estimule ações de intervenção arquitetônica mais conscientes, também no contexto brasileiro.

Title: Old but Gold: LLM-Based Features and Shallow Learning Methods for Fine-Grained Controversy Analysis in YouTube Comments Authors: Bassi, Davide; Marino, Erik; Vieira, Renata; Farina-Pereira, Martin Abstract: Online discussions can either bridge differences through constructive dialogue or amplify divisions through destructive interactions. paper proposes a computational approach to analyze dialogical relation patterns in YouTube comments, offering a fine-grained framework for controversy detection, enabling also analysis of individual contributions. experiments demonstrate that shallow learning methods, when equipped with these theoretically-grounded features, consistently outperform more complex language models in characterizing discourse quality at both comment-pair and conversation-chain levels.studies confirm that divisive rhetorical techniques serve as strong predictors of destructive communication patterns. work advances understanding of how communicative choices shape online discourse, moving beyond engagement metrics toward nuanced examination of constructive versus destructive dialogue patterns.

Title: Linguistic Markers of Population Replacement Conspiracy Theories in YouTube Immigration Discourse Authors: Marino, Erik; Bassi, Davide; Vieira, Renata Abstract: This paper presents a linguistic analysis of YouTube comments related to immigration discourse, analyzing the contrasts between standard anti-immigration comments and those linked to Population Replacement Conspiracy Theories (PRCT). Using a dataset of 71,137 YouTube comments classified into three stance categories (PRO, NEUTRAL, CONTRA) and PRCT annotation, we analyze the linguistic features of each group through LIWC (Linguistic Inquiry and Word Count). Our findings reveal significant differences in the language patterns of PRCT comments, both in comparison to standard anti-immigration discourse (CONTRA) and to all other groups. These differences appear particularly in religious references, power dynamics, conflict framing, and emotional tone. The high linguistic overlap (89.7%) between conspiracy and non-conspiracy anti-immigration discourse reveals the subtle nature of these differences. These distinctive linguistic patterns provide valuable insights both for the understanding and the automatic detection of conspiracy theories in online discourse, contributing to the growing body of research on computational approaches to identifying harmful content online.

Title: Notes on variation and lexical diachrony in the Parish Memories-Alentejo collection (1758) Authors: Cameron, Helena; Olival, Fernanda; Vieira, Renata Abstract: Memórias Paroquiais-Alentejo (1758) collects the responses of the parish priests from the largest region of Portugal (Alentejo) to a survey carried out by the Crown, asking about the state of the territory and its populations, and also about the effects of the earthquake 1755. This article discusses the transformative process from the manuscripts up to the processable digital stage. We described some individualising characteristics of the lexical “corpus” obtained with PLN. Marks of lexical diachrony also stand out, revealing society and its uses in the mid-18th century.
