The ability of sports federations to self-regulate is a profession of faith in the governance of global sports, even as a defense measure against attempts at political appropriation of the virtues of sports ideas, especially by autocratic or totalitarian regimes, as seen, for example, in "Nazification" of the aesthetics of the Berlin Olympic Games in 1936, or the use of sport as a piece of propaganda during the Cold War, in the second half of the 20th century. However, the possible hypocrisy of the discourse of an alleged purity of ideals defended by sporting autonomy has been exposed by successive episodes of abuse and corruption by sector leaders, at the most diverse levels, generating government reactions in order to issue norms that allow a greater degree of state intervention in sport. Given this situation, the work proposes governance standards that can preserve sports self-regulation, especially from the point of view of democratization of national and international federations and in light of the regulatory innovations issued by FIFA and the International Olympic Committee, in reaction to the episodes that undermine the credibility of global sports governance.
Electric propulsion optimizes propellant mass and meets new propulsion device demands. These devices adjust satellite orbits and enable long missions. Among various thrusters, electrostatic ones have well-defined physics, simplifying operational parameter optimization. This study developed a global model for an Inductively Coupled Plasma (ICP) cylindrical ion thruster with an output polarized grid system. Argon propellant is injected into the chamber, and ICP plasma is generated by a radiofrequency current. Neutral and excited species are accelerated out by diffusion, while ionized species are accelerated via the polarized grids' electric field. The polarized grid system was optimized for better plasma sheath use. The model considers single and multi-step ionization, the Electron Energy Distribution Function (EEDF), neutral gas, and electron power balance equations. Excited species influence ionization energy, but not ionic density. However, the ion substitution rate increases, essential for thrust and specific impulse. The model determines the neutral gas temperature by considering the power balance and interactions with other species.
"Building Education Together (BET): Reducing dropout rates in English as a Foreign Language programs through enhanced collaboration and motivation. In Chile, the high dropout rate of English programs places the country among those with the lowest proficiency levels globally. This study aims to decrease these rates by creating high-quality materials based on gamification, Information and Communication Technology (ICT), and collaborative work. The intervention, conducted with adult learners in an institute in Santiago, revealed that the combination of games, technology, and future-oriented tasks significantly increased motivation and classroom participation, while also reducing dropout intentions. The results indicate that a collaborative and motivational educational approach can improve students' confidence and future self-image, contributing to effective English learning."
Este pequeno livro não é um curso de astrofísica, tampouco um estudo acadêmico, mas apenas comentários complementares, em linguagem simples, sobre alguns temas já estudados pela astrofísica, trazendo novas interpretações com o objetivo de propiciar novas reflexões, acadêmicas ou não. Discorre sobre a razão de as noites serem escuras, propõe ensaio para a verificação de característica eletromagnética da atração gravitacional (com contraposição ao conceito de deformação do tecido espaço-tempo), apresenta nova explicação do campo magnético terrestre (com contraposição ao conceito de movimentos do manto terrestre), afirmando que somente o movimento de elétrons é c...
Este primeiro volume dedicado ao estudo do direito administrativo contratual tem origem em profunda pesquisa e sistemática consolidação dos materiais de aula acerca de temas que despertam crescente interesse no meio jurídico e reclamam mais atenção dos estudiosos do direito. A intenção da Escola de Direito do Rio de Janeiro da Fundação Getúlio Vargas é tratar de questões atuais sobre o tema, aliando a dogmática e a pragmática jurídicas. A obra trata, de forma didática e clara, dos conceitos e princípios do direito administrativo, analisando as questões em face das condições econômicas do desenvolvimento do país e das discussões recentes sobre o processo de reforma do Estado.

This volume gathers selected peer-reviewed papers presented at the XXVI International Joint Conference on Industrial Engineering and Operations Management (IJCIEOM), held on July 8-11, 2020 in Rio de Janeiro, Brazil. The respective chapters address a range of timely topics in industrial engineering, including operations and process management, global operations, managerial economics, data science and stochastic optimization, logistics and supply chain management, quality management, product development, strategy and organizational engineering, knowledge and information management, work and human factors, sustainability, production engineering education, healthcare operations management, disaster management, and more. These topics broadly involve fields like operations, manufacturing, industrial and production engineering, and management. Given its scope, the book offers a valuable resource for those engaged in optimization research, operations research, and practitioners alike.
