Estudo preliminar sobre a liberdade de expressão na perspectiva dos marcos regulatórios das mídias sociais
(Universidade Federal de Goiás, 2024-02-05) Bezerra, Isabella Alves; Rezende, Laura Vilela Rodrigues;; Rezende, Laura Vilela Rodrigues; Santos, Andréa Pereira dos; Castro, Maria das Graças Monteiro
This dissertation examines the complex and dynamic intersection between disinformation and freedom of expression in the context of social media, which have become central arenas for the formation of public discourse. The study also proposes a critical analysis aiming to understand how Brazilian and foreign legislation present their regulations on content moderation with a view to combating misinformation and the context of dark interests that involve large social media companies. The methodology used is qualitative, and uses theoretical review and documentary research to build a theoretical framework based on the ideas of different authors on the topic, in addition to presenting a comparative study between current social media regulations. It is concluded that there must be a necessary balance involving the critical education of citizens, clear, objective and transparent rules provided by social media and legislation that regulates these tools, whose operation is based on profit to the detriment of any protection that can be established for citizens who use them.
Corpos e gritos de desencurralamento: performances como expressão das territorialidades geraizeirinhas
(Universidade Federal de Goiás, 2023-12-07) Souza, Jonielson Ribeiro de; Hartmann, Luciana;; Hartmann, Luciana; Salgado, Ricardo de Seiça Alves; Lopes, Jader Janer Moreira; Veloso, Jorge das Graças; Corrêa Júnior, Sebastião Rios
This work presents a reflection on the relationships between theatrical performances by Gerazeiras children and adolescents and the ways of being and living in their communities in contexts of socio-environmental conflicts. Combining ethnography and theater, this research seeks to understand how children and adolescents are involved in these processes and how such relationships would be expressed in theatrical performances performed by them, which leads us to call this methodological proposal a performative ethnography. To this end, observant participation in the communities involved, provided by the author's experience in struggle processes or everyday events, combined with practices such as walks through their territories, are added to theatrical initiation workshops for children and adolescents taught by the author.
[Des]construção e [res]significação dos direitos humanos: um estudo com vivências de ensino-aprendizagem e análises sociológicas
(Universidade Federal de Goiás, 2024-01-25) Brito, Gabrielle Amâncio Bertolli Venâncio; Rabelo, Danilo;; Rabelo, Danilo; Oliveira, Dijaci David de; Vreeswijk, Anna Maria Dias
Faced upon a convoluted moment over a polarized political context with different and opposite ideas, the conception of human rights lies as “privilege” for criminals. Such annalysis is sustained by both population and commom sense. This work presents the results of a research made with second grade classes from Ensino Médio (Brazilian High school) in a full-time public school in Goiânia, Goiás. In order to do so the following investigation problem has been set: How to (de)construct the human rights conception and (re)define it through sociology classes? This research aims to understand the human rights concept lying (or not) in Ensino Médio students’ speech, opposing the bias that such rights are “bandits” privilege. To deconstruct such alignaments – sustained by social and historical visions shaped within neoliberalism interest, means to construct a critical perspective of human rights biased over multiculturalism through a teaching Project that sustains this Dissertation process. The pedagogic interventions were set upon the teaching Project entitled “Afinal, o que são esses tais direitos humanos?” (Afterall what are the so-called human rights?) developed in Sociology classes. Such Project is a founding part of the previously mentioned research and also part of the Professional Master in Science stricto sensu from the post-grad program in Basic Education teaching in the Research and Teaching Education Applied center (CEPAE – Centro de Ensino e Pesquisa aplicada à Educação) from the Federal University of Goiás (UFG), thus named educational product, available in appendix. The research is made upon qualitative bias and fundamented over theoreticals that worked with the history of human rights and its concepting, such as Giuseppe Tosi (2004), Norberto Bobbio (2004), Hannah Arendt (1989, João Dornelles (2013) and Boaventura Santos (1997). The theoretical fouding is set also in human rights educators such as Candal (2008), Sacavino (2013) and Paulo Freire (2019), scholars that annalysed a democratic and humanizing education. Such authors work with the plurality of understandings in the concept of human rights in several theoretical and historical perspectives, developed over a democratic focus, universally centralizer of rights, or with a neoliberalism perspective. Due to a common sense deconstruction of human rights and its following reconstruction, normatizing documents of the school curricum are annalysed, the Nacional Curricular Commom Base (BNCC, 2018) and the Curricular Document for Goiás – Ensino Médio part (DC-GOEM, 2020). The field research is characterized by an action-research with the school environment collaboration objective and the recognition of subjects in its following parts as developers of a democractic and rights protective environment. The data collection happened through quizzes, semistructured interviews and teaching and project observation. The reflections were made upon field diary annalysis and student developed production, meaning to understand which is the guiding line that directs the student claimed human rights conception.
Abordagem de seleção de características baseada em AUC com estimativa de probabilidade combinada a técnica de suavização de La Place
(Universidade Federal de Goiás, 2023-09-28) Ribeiro, Guilherme Alberto Sousa; Costa, Nattane Luíza da;; Barbosa, Rommel Melgaço;; Barbosa, Rommel Melgaço; Lima, Marcio Dias de; Oliveira, Alexandre César Muniz de; Gonçalves, Christiane; Rodrigues, Diego de Castro
The high dimensionality of many datasets has led to the need for dimensionality reduction algorithms that increase performance, reduce computational effort and simplify data processing in applications focused on machine learning or pattern recognition. Due to the need and importance of reduced data, this paper proposes an investigation of feature selection methods, focusing on methods that use AUC (Area Under the ROC curve). Trends in the use of feature selection methods in general and for methods using AUC as an estimator, applied to microarray data, were evaluated. A new feature selection algorithm, the AUC-based feature selection method with probability estimation and the La PLace smoothing method (AUC-EPS), was then developed. The proposed method calculates the AUC considering all possible values of each feature associated with estimation probability and the LaPlace smoothing method. Experiments were conducted to compare the proposed technique with the FAST (Feature Assessment by Sliding Thresholds) and ARCO (AUC and Rank Correlation coefficient Optimization) algorithms. Eight datasets related to gene expression in microarrays were used, all of which were used for the cross-validation experiment and four for the bootstrap experiment. The results showed that the proposed method helped improve the performance of some classifiers and in most cases with a completely different set of features than the other techniques, with some of these features identified by AUC-EPS being critical for disease identification. The work concluded that the proposed method, called AUC-EPS, selects features different from the algorithms FAST and ARCO that help to improve the performance of some classifiers and identify features that are crucial for discriminating cancer.
A poesia slam e suas des-margens
(Universidade Federal de Goiás, 2023-11-17) Boleão, Jossier Sales; Martins, Alice Fátima;; Martins, Alice Fátima; Andrade, Emile Cardoso; Santos, Michelle dos; Guimarães, Leda Maria de Barros; Meira, Elinaldo da Silva
This thesis is an exercise in looking at slam poetry, focusing on the movement in Brazil and making some reflections from the field of Visual Culture. Slam poetry emerged in the early 1980s in the United States and since then has spread to several countries. In Brazil, slam poetry arrived in 2008, the country being one of the references for the quantity and diversity of slam groups spread, in addition to other elements that make up many particularities of each group. The notes made in this text follow the trajectory that begins in the autobiographical path and expands in avenues when finding slam poetry, and understanding it as a poetic act, transfiguring itself into energy of resistance and occupation of seeing, hearing and feeling. The direction in which the thesis is constituted arose from the following questions: what visualities and countervisualities do slammers promote, summon and provoke, from the poems that overflow their bodies? Which narratives mobilize and want to propose? The consequences resulting from these inquiries originate in the investigative work that began in 2019, from the participation in poetic slam battles, in the city of Goiânia, in Goiás and, with the arrival of the covid­19 pandemic, the research moved to the competitions that took place in the environment of digital platforms. Given this context, the material that drives the reflections presented here is diverse and comprises various nuances of what already exists in the systematization of slam poetry. That being said, the perspective addressed supported by visual culture covers the dimensions of the poetic act from a pedagogy of slam poetry, from its understanding as cirandas of knowledge anchored in popular education and in the politics of the word, in which the need becomes a voice and the poem becomes the terrain of revolution, since the event in the format of popular assemblies, adding the competitive element between artist poets. In addition, this thesis follows the paths of slam poetry as an insurgency through counterpoetry, in its decolonial exercise, since its aesthetics goes towards the sanación of colonial wounds, having as its power the poetic fabrication of the visual city, without losing the reflections of a pandemic poetics in a regime of denial in Brazil governed by the extreme right­wing, until the year 2022. It finally enters the conditions of this poetic work during long­distance connections by populating digital platforms with poetry and other sensitive exercises. The systematized elements are not intended to show fixed answers, but to point to other perspectives of looking at the slam poetry movement and at artists who reconfigure the scene in everyday life.
