Trabalho de Evento Are Large Language Models Moral Hypocrites? A Study Based on MoralFoundations(2021) José Luiz Nunes; GUILHERME DA FRANCA COUTO FERNANDES DE ALMEIDA; Araujo, Marcelo de; Barbosa, Simone D. J.Large language models (LLMs) have taken centre stage indebates on Artificial Intelligence. Yet there remains a gap inhow to assess LLMs’ conformity to important human values.In this paper, we investigate whether state-of-the-art LLMs,GPT-4 and Claude 2.1 (Gemini Pro and LLAMA 2 did notgenerate valid results) are moral hypocrites. We employ tworesearch instruments based on the Moral Foundations The-ory: (i) the Moral Foundations Questionnaire (MFQ), whichinvestigates which values are considered morally relevant inabstract moral judgements; and (ii) the Moral FoundationsVignettes (MFVs), which evaluate moral cognition in con-crete scenarios related to each moral foundation. We charac-terise conflicts in values between these different abstractionsof moral evaluation as hypocrisy. We found that both mod-els displayed reasonable consistency within each instrumentcompared to humans, but they displayed contradictory andhypocritical behaviour when we compared the abstract val-ues present in the MFQ to the evaluation of concrete moralviolations of the MFV.Trabalho de Evento Implantação de sistema orçamentário participativo em uma empresa do ramo de educação e saúde(2024) Silva, Emersson Luan dos Anjos; Ricci, Tatiana Gama; Oyadomari, José Carlos Tiomatsu; Parisi, ClaudioEste relato técnico apresenta a experiência do setor de controladoria na adoção de um sistema orçamentário participativo, integrado e de acesso em tempo real pelos gestores, em uma organização do ramo de educação e saúde. O estudo foi realizado por meio de uma pesquisa descritiva e explicativa e levou em consideração: o contexto, a intervenção, a descrição de como o problema foi solucionado e apresentação dos resultados. A implantação de um novo sistema para elaboração do orçamento foi determinante para melhorias de processos internos, otimização de recursos humanos, ganhos de eficiência e fornecimento em tempo real das informações para os tomadores de decisões, além de responsabilização dos gestores e maior confiabilidade das informações. Os resultados analisados concluíram que o novo sistema colaborou para diminuição do tempo gasto com consolidação de planilhas, diminuição de erros e atribuição de responsabilidade aos gestores, sendo que as dificuldades apontadas foram a falta de compreensão e de conhecimento no preenchimento das informações no novo sistema pelos usuários, curto tempo de treinamento para utilização da nova ferramenta, diminuição na agilidade para realizar determinados recálculos e sistema menos maleável do que o Excel.Trabalho de Evento Continuous Parameter Control Using an On/Off Sensor in the Augmented Handheld Triangle(2021) Ferreira, Marcio Albano H.; TIAGO FERNANDES TAVARESIn this work, we present Triaume, an augmented musical percussion instrument based on the triangle. The augmentation proposal for this instrument is based on a capacitive thumb sensor, that allows controlling digital musical devices and at the same time, preserves the original instrument idiomatic inside the context in which it is inserted. Triaume’s interaction proposals were built upon Brazilian music genres idiomatic, such as Forro, Xote, and Bai ´ ao. The instrument ˜ invasiveness is further reduced through the use of an external device (an appli cation running on a smartphone) for emulating faders related to sound parameter configuration. At first, we used the sensor as an on/off button able to trigger pre programmed percussion samples, which can be synchronized with the triangle’s acoustic sounds. This mechanism can be adjusted for triggering on pressing or releasing the sensor. Next, we convert the digital signals acquired by the sensor to continuous values by the on/off signal filtering. Such signal rectification and filtering system allows gradual change of continuous sound synthesis parameters, dealing with the on/off signal low robustness, turning it into a more controlled sig nal. Triaume can be inserted in the contexts of traditional and avant-garde music, also motivating further studies for applying the mechanism used on it in other percussion instruments.Trabalho de Evento InFracta: the Body as an Augmented Instrument in a Collaborative, Multi-Modal Piece(2021) Pessanha, Thales Roel P.; Roque, Thiago Rossi; Zanchetta, Guilherme; Pereira, Lucas B.; Oliveira, Gabrielly Lima de; Pinheiro, Bruna C. M.; Paulino, Renata F. P. P.; TIAGO FERNANDES TAVARESThis paper discusses the creative process of the piece “InFracta: Dialogue Processes in a Multi-modal Environment”. The discussion concerns the dialogues between the dance, music, image, and technology knowledge domains, which were all present in the construction of the piece’s poetics. The interaction between these domains fostered resignifying the dancers’ gestures, so that their bodies interacted with a sound environment as if they were augmented instruments. This discussion adds to previous work on technology-mediated multi-modal art, in special concerning the contribution and the emergence of meaning related to each of the knowledge domains involved in the piece.Trabalho de Evento Comparative Latency Analysis of Optical and Inertial Motion Capture Systems for Gestural Analysis and Musical Performance(2021) Santos, Geise; Wang, Johnt; Brum, Carolina; Wanderley, Marcelo M.; Tavares, Tiago; TIAGO FERNANDES TAVARES; Rocha, AndersonWireless sensor-based technologies are becoming increasingly accessible and widely explored in interactive musical performance due to their ubiquity and low-cost, which brings the necessity of understanding the capabilities and limitations of these sensors. This is usually approached by using a reference system, such as an optical motion capture system, to assess the signals’ properties. However, this process raises the issue of synchronizing the signal and the reference data streams, as each sensor is subject to different latency, time drift, reference clocks and initialization timings. This paper presents an empirical quantification of the latency communication stages in a setup consisting of a Qualisys optical motion capture (mocap) system and a wireless microcontroller-based sensor device. We performed event-to-end tests on the critical components of the hybrid setup to determine the synchronization suitability. Overall, further synchronization is viable because of the near individual average latencies of around 25ms for both the mocap system and the wireless sensor interface.Trabalho de Evento Evaluating mastery-oriented grading in an intensive CS1 course(2024) Montagner, Igor dos Santos; RAFAEL CORSI FERRÃO; Kurauchi, Andrew; Silva, Mariana; Zilles, CraigAllowing students to re-attempt assessments has been shown to be effective in traditional university-level courses in improving student mastery of course content. In this paper, we analyse an intensive programming introductory experience, where first semes ter university students’ full load is a single semester-long course that teaches the basics of programming and software engineering. We study its use of mastery-based grading: offering five (formative) low-stakes quizzes (with retakes), each focused on a single topic, and five (summative) higher-stakes exams that assess all learn ing objectives. Our research questions are: (i) “Do second chances help students to increase their performance over time in intensive courses?”; and (ii) “Are second chances effective in reducing stress/- mental load/weight of assessments in intensive courses?”. We find that (i) offering second chances on quizzes decreases the number of students at risk of failing before the first exam; (ii) students’ proficiency in coding tasks (as measured by exam grades) improve during the semester; and (iii) that our schedule reduces anxiety and mental load for students, but only after students take the first chance.Trabalho de Evento Using Multi-objective Optimization to Generate Timely Responsive BDI Agents(2022) Stabile Junior, Márcio FernandoA BDI agent’s ability to perform well depends on its reasoning time.If the reasoning is slow, it is possible that the environment has changed and the action selected is no longer optimal by the time the agent has finished to deliberate. This work then builds a BDI architecture using Anytime Algorithms that can control the amount of time used by the agent to reason and act on the environment. I briefly describe the proposed architecture and its implementation in the Jason agent language.Trabalho de Evento Game development learning with PBL approach as a tool to assess computer engineering competences(2023) Freme, Pedro H. E. P; Sanches, Thiago; LUCIANO PEREIRA SOARESThis paper presents strategies for a Game Development course that aims to develop hard and soft skills in computer engineering students. There is a focus on soft skills that are considered essential for success in the 21st-century professional world. The design for this course is based on the Project-Based Learning approach, which allows students to explore different techniques and encourages creativity, while still having clear objectives and pre-defined milestones. The article discusses the use of continuous monitoring, peer assessments, and the Agile project approach to evaluate student progress and ensure that each student experiences different roles in project management.Trabalho de Evento Adapting SCRUM Ceremonies in Undergraduate Capstone Projects(2022) Ziv, Hadar; Kalafatis, Stavros; LUCIANO PEREIRA SOARES; Prikladnicki, RafaelTrabalho de Evento Pair Teaching in Computer Graphics(2022) LUCIANO PEREIRA SOARES; FABIO ORFALIComputer Graphics is a course commonly found on Computer Science and Computer Engineering undergraduate programs. There are some convenient points on teaching computer graphics in these programs: Computer-Generated Imagery in movies and videogames are relevant examples of applied engineering and science that students experience in their lives, and this can be a potential motivation factor for students to get engaged on learning; furthermore, Computer Graphics relies on several fundamental and complex mathematical concepts, that can also be applied in other science areas, being an opportune moment to cover and practice mathematical learning goals, all connected with a base on computer science. Learning Computer Graphics depends on developing and integrating skills on computer science and mathematics, therefore, a learning plan must cover both topics. However, it must be considered that students need to relate these topics, and this is the trick, since ideally professors need the knowledge and pedagogy in both areas. The strategy presented in this document was based on two professors, one mathematician and one computer engineering, planning, and teaching an elective undergraduate course on Computer Graphics. The course was based on active learning strategies by design, heavily focused on Project Based Learning through three projects starting from scratch, each week learning and implementing new features on the projects. Students must program in regular programming languages like Python, C++ and Javascript, and build up their competence in mathematics from basic math concepts. As a result, students were able to develop a scanline renderer, and a ray-tracing renderer without any graphical Application Programming Interface and finally a 3D web application based on ThreeJS. Although students had a perception of a demanding course, they were engaged on proposed activities during all semester, and were able to implement all important features on projects, often above expectation, showing evidence that learning objectives were achieved.
