Title: Pós-edição humana apoiada por anotações de erro: um estudo de caso para textos científicos de português brasileiro para inglês Autor: Nürmberg, Rodrigo Schmidt Primeiro orientador: Spanhol, Fabio Alexandre Abstract: The internet and globalization have boosted the demand for translation services. In this scenario, the automated translation of texts, by means of computer programs, aims to meet part of this demand and improve the productivity of translators. However, problems with the quality of automated translation are accentuated in specific contexts, due to the characteristics of the domain, such as the translation of scientific texts, an area in which more than 80% of all world publications are in English. The improvement in the fluency of automated translations makes it difficult to identify such errors, demanding additional attention from proofreaders. A case study was conducted to investigate whether error annotations, generated by quality estimation models of automated translations, can support translators in the post-editing of scientific texts, translated from Brazilian Portuguese into English, with a view to increasing the productivity and quality of translations. No evidence of increased productivity was found, associated exclusively with the presence of highlights. The quality assessments are still under analysis and their results will be communicated in due course. Although translators in the highlighted modalities corrected 1.5 times more critical errors than those in the No highlighted modality, no significant differences were found in quality averages between the modalities. In terms of usability, participants acknowledged the influence of highlights on post-editing, but their perception of its usefulness was mixed.

Title: Uma aplicação de visão computacional para detecção automática de defeitos em pavimentação asfáltica urbana no Brasil Autor: Borges, Marcos Augusto Primeiro orientador: Spanhol, Fabio Alexandre Abstract: Road infrastructure maintenance is a cornerstone of well-functioning cities, as it directly influences urban mobility, traffic safety, and the efficiency of transporting people and goods. However, the natural deterioration of pavements—compounded by increasing traffic and the lack of adequate preventive maintenance—leads to recurrent damage that affects both users and public management. In this context, efficient monitoring methods are indispensable to ensure roadway quality and to reduce costs associated with emergency interventions. This work aims to develop an automated system for detecting damage in asphalt pavements using computer vision and deep learning techniques. Among the principal challenges addressed are the accurate identification and classification of different defect types: fissures (cracks), deformations, ravelling (surface wear), potholes, and patches. We present a publicly available dataset of high-resolution digital images of urban pavements, structured in accordance with Brazilian standards and accompanied by per-image annotations curated by a technical committee. The study also proposes an efficient methodology for automated roadway condition assessment based on images collected with a smartphone mounted on the bumper of a passenger vehicle. The model trained with YOLOv5 achieved an mAP@50 of 84.4%. These results are intended to support public administrations in making decisions about maintenance and interventions, leading to improvements in the quality and safety of road infrastructure.

Title: PROUNI: Democratização do acesso ao ensino superior ou estímulo a expansão das instituições de ensino superior privadas? Autor: Vasconcelos, Juliana Padilha de Primeiro orientador: Reis, Luiz fernando Abstract: This dissertation has as its research object the University for All Program (PROUNI), specifically between the years 2005 and 2020. The central objective of this research is to carry out an analysis of the program's data within the mentioned period and based on this analysis, seek to understand the beneficiaries, with the following central question: Did PROUNI democratize access to higher education or stimulate the expansion of private higher education institutions? To this end, during the research we will analyze the program since its creation through a Provisional Measure and its changes over the years, after which we will demonstrate, through the data collected, offered by the government, the number of scholarships offered, specifying by modality, race , gender, region and type of scholarship, we will also bring the twenty courses with the highest number of scholarships offered per five-year period (2005, 2010, 2015 and 2020) and finally we will demonstrate the government's tax expenditure on the program, considering that its existence is through tax exemptions granted to private higher education institutions, that is, we will verify in practice during the research how much public coffers effectively stopped making profits to maintain the program. Starting from the presentation of the data, we can then analyze the whole and seek understanding for all those benefiting from the program, whether they are scholarship holders or institutions.

Title: Sujeito, memória, contradições: uma análise discursiva dos pronunciamentos de Jair Bolsonaro no início da pandemia de covid-19 Autor: Araújo, Alcemar Dionet de Primeiro orientador: Soares, Alexandre Sebastião Ferrari Abstract: This study analysed the official statements made by President Jair Messias Bolsonaro and broadcast on national radio and television in March and April 2020. These statements addressed the processes of meaning production in relation to the ongoing pandemic. Using the theoretical framework of French-oriented discourse analysis, we sought to identify discursive regularities, traces of discursive memory and contradictions in these statements. Additionally, we investigated the extent to which these discourses serve as a privileged 'place' for understanding how subjects organise themselves within power relations through discourse. The study draws on the work of authors Pêcheux (1988, 2008, 2014), Orlandi (1987, 1999, 2005), Mariani (1996, 1998, 2007), Daltoé (2024), Indursky (1999, 2011, 2020), and Petri and Venturini (2021), who support the idea that political discourse is permeated by divisions in meaning when considering the historical, ideological and social position of the speaker. Our analysis suggests that, as utterances inscribed in certain discursive formations, Bolsonaro's pronouncements present slips and fissures that are inherent to the functioning of language. This allows for the production of meanings that are not entirely controlled by the subject. As Pêcheux (1988) pointed out, 'there is no ritual without flaws'; even gestures of enunciation marked by authority and attempts at stabilisation produce contradiction, establishing the possibility of displacements, resistances and reinterpretations. Thus, the so-called 'flaws' designate the way in which discourse escapes the subject and creates spaces for the construction of new meanings. In this way, this thesis contributes to reflection on political discourse in times of crisis by addressing the dynamics of power and the discursive functions mobilised during the pandemic. These are traversed by contradictions, displacements and effects of meaning that sustain certain ideological positions. Publisher: Universidade Estadual do Oeste do Paraná Tipo do documento: Tese
