O teletrabalho e a gaiola de silício: autonomia, controle e resistência no contexto da pandemia de Covid-19
(Universidade Federal de São Carlos, 2025-03-27) Veloso, Braian Garrito; Lima, Jacob Carlos; https://lattes.cnpq.br/9244132532446607; https://orcid.org/0000-0001-6475-9575; https://lattes.cnpq.br/2537302046587655; https://orcid.org/0000-0002-9459-5740
This research has, as a general objective, to analyze the trends in new processes of technification of contemporary life revealed from the experience of transition from face-to-face work to teleworking in the context of the Covid-19 pandemic. We start from the hypothesis that this experience of change is fertile ground for observing the main characteristics that involve the relationships between workers and digital technologies within a specific historical-social framework that, in this thesis, we defend based on the original concept called silicon cage. The specific objectives are: to describe and define the characteristics of teleworking, considering its specificities in the context of the Covid-19 pandemic; identify the objective conditions of teleworking in the context of the pandemic and beyond of it; understand the relationship between workers and digital technologies and the resulting implications; investigate changes from face-to-face work to teleworking based on modulations of time, space and subjective engagement in light of the perception and experience of autonomy; and explain the transition from the iron cage to the silicon cage. When it comes to methodology, it is a qualitative approach that included convenience sampling. The study starts from a phenomenological perspective in that it emphasizes the subjects' experience and their perceptions. Regarding methodological procedures, we used: narrative bibliographic review, virtual questionnaire and semi-structured interviews. Based on some of the main results, it was observed that, in the pandemic, the relationship between workers and technologies involved, in some cases, important resignifications in the ways in which subjects understand digital technological resources; the experiences of teleworkers during the pandemic are also related to previous objective conditions; modulations in teleworking, when combining time and space, tend to promote overload situations; and the use of mobile technologies contributes to the configuration of what we call the silicon cage as a process of technification of contemporary life.
Professores da UFT no ensino remoto: caracterização da sociedade de risco e análise do espaço-tempo pela teoria ator-rede

Contemporary society has witnessed the evolution of digital technologies in a wide range of sectors. In the field of education new ways of teaching and learning using these tools are also being experienced or discussed. In the years 2020/2021, we experienced a pandemic caused by the Sars-CoV-2 virus and, to face this situation, in schools and universities there was emergency remote teaching. In this thesis, the sociotechnical network that configured emergency remote teaching in higher education at the Federal University of Tocantins (UFT) at the Arraias/TO campus during the aforementioned period was investigated.This is a qualitative research, with field research, through interviews with thirteen professors from the five in-person undergraduate courses at this university. The main objective was to characterize emergency remote teaching as part of the risk society as defined by Ulrich Beck. We also used Bruno Latour's Actor-Network Theory (ANT) to understand the space and time that were performed in this sociotechnical network, highlighting deviations, compositions, and networks. The expression globalization-minus, defined by Latour (2020) to identify situations in times of crisis, will also be used. The main results were: TAR provided us with another bias in the perception of the sociotechnical network that involved space and time in emergency remote teaching, in which it deepened the understanding of the sociotechnical networks involved, examining how space, time, actors and practices were incessantly formed and negotiated. It was found that a situation of immediacy was performed on the part of students when it came to obtaining feedback from teachers; the issue of delays in synchronous meetings was perceived differently from in-person teaching. The connections between remote teaching and science, technology, politics, society, health and education became more visible. Regarding the risk society, it was evident that this period was very complex, bringing to light anguish, stress, insecurities, anxieties and a lot of uncertainty, by the interviewees in this unprecedented situation, due to the speed of decision-making in an uncertain scenario. The sketches of the networks also show the unprecedented scenario that was performed in this teaching.
Modelo matemático e computacional para robôs espaciais de base livre e múltiplos braços com momento não-conservado
(Universidade Federal de São Carlos, 2025-03-27) Rodrigues, Gabriel da Silva; Pazelli, Tatiana de Figueiredo Pereira Alves Taveira; https://lattes.cnpq.br/2574900514697052; https://lattes.cnpq.br/9268113350374242; Siqueira, Adriano Almeida Gonçalves; Malavolta, Alexandre Tácito; https://lattes.cnpq.br/2935052598064187; https://lattes.cnpq.br/8477313173581967
The development of orbital space robotics in recent decades is aimed at meeting the demand for extra-vehicular missions, such as supply, maintenance, inspection, rescue and transport of materials. A space manipulator can be defined by one or more arms attached to a floating base (satellite) designed for operation in orbit. The distinguishing characteristic of these systems is the dynamic coupling between the base and the manipulators. In this work, a mathematical model is proposed for a space robot with multiple arms and a floating base, capable of dealing with external forces and non-zero linear and angular momentum, especially to maximize the fidelity between the model and the robot in detumbling applications. The main objective is to present a mathematical model that is sufficiently detailed in the constructions of vectors and matrices necessary for its implementation, maintaining its functional generality and consistency with the real operation of the manipulator in terms of obedience to the laws of classical mechanics. The work in question addresses gaps in the literature regarding the dynamic model in Cartesian space and the behavior of the robotic system in conditions of interaction with non-cooperative targets, such as inconsistencies in the calculations of non-inertial terms and angular momentum, mapping of forces between joint and task domains through the Generalized Jacobian Matrix and cancellation of momentum in post-impact situations. From simulations, it is clear that the presented formulations are internally consistent in joint and inertial domains. The application of multiple target stabilization tasks, whose formulation is based on the generalization of the spatial Jacobian for multiple arms, presented satisfactory performance, thus assuming a relevant role in future applications involving multiple target detumbling.
