No. of bitstreams: 1 DIS_GICELDA_JULIA_DAL_BO_COMPLETO.pdf: 3328714 bytes, checksum: c1dae6f11752d09fdfaddc8e2f46a7ce (MD5) Previous issue date: 2017-03-09 / This dissertation explores structures of power from the point of view of empowerment and resistance in a shared economy model, having Uber (since its arrival in the country) as object of study. To this end, it relies on a qualitative method of interpretativist approach through a single case study. By identifying the agents' discourses of the urban mobility socio-technical system, in the voice of media vehicles and specialized websites, this research proposes to analyze how power structures are organized. The study lists three perspectives, an ?economic model?, a ?business model? and ?sustainable development?, built to group the ?two sides of the same coin?, empowerment and resistance, proposing a ?conversation? between them. It presents a view of the relationship with the collectivity through two mechanisms, also of opposing forces: ?quest for legitimacy? and ?reinforcement to the status quo?. In a complementary way, it proposes a discussion section about uberism and its variations. Among the aspects listed in this section, issues of regulation and characteristics of the so-called Uber economy stand out. It brings, as theoretical basis, concepts of the Transition Theory for Sustainable Development, the Multiple Level Perspective (MLP) and an applied study that links sharing economy to the notion of socio-technical systems. With this, it seeks to demonstrate the ?game? of forces between empowerment and resistance in the Brazilian context of the socio-technical system of urban mobility. A combination of technological trajectories that have been destabilizing and pressuring the existing socio-technical structures pointed out for the existence of transitions to sustainable development. / Esta disserta??o explora estruturas de poder sob o ponto de vista de empoderamento e de resist?ncia em um modelo de economia compartilhada, tendo a Uber (desde sua chegada ao pa?s) como objeto de estudo. Para tal, apoia-se em um m?todo qualitativo de abordagem interpretativista por meio de um estudo de caso ?nico. Prop?e-se a analisar como est?o organizadas as estruturas de poder identificando os discursos de agentes do sistema sociotecnico de mobilidade urbana na voz dos ve?culos de m?dia e de sites especializados. O estudo elenca tr?s perspectivas, modelo econ?mico, modelo de neg?cio e desenvolvimento sustent?vel, constru?das de forma a agrupar os ?dois lados da mesma moeda?, empoderamento e resist?ncia, propondo uma ?conversa? entre eles. Apresenta um olhar da rela??o com a coletividade atrav?s de dois mecanismos, tamb?m de for?as contr?rias: ?busca por legitimidade? e ?refor?o ao status quo?. De forma complementar, prop?e uma se??o de discuss?o acerca de uberismo e suas varia??es. Dentre os aspectos elencados nesta se??o, destacam-se quest?es de regula??o e caracter?sticas da chamada Uber economia. Como suporte te?rico apresenta conceitos da Teoria das Transi??es para o Desenvolvimento Sustent?vel, da Perspectiva de M?ltiplos N?veis (MLP) e de um estudo aplicado que vincula economia compartilhada ? no??o de sistema sociot?cnico. Com isso, busca demonstrar o ?jogo? de for?as entre empoderamento e resist?ncia no contexto brasileiro do sistema sociot?cnico de mobilidade urbana. Os resultados apontaram em dire??o a exist?ncia de transi??es para o desenvolvimento sustent?vel, permeadas por uma combina??o de trajet?rias que tem desestabilizado e pressionado as estruturas sociot?cnicas vigentes.

To deal with these contingencies, companies use Control Centers of Operations (CCOs), whose responsibility involves planning and monitoring the execution of planning their flight schedules while attempting to accommodate the variability encountered. This type of activity creates the need for the system to be resilient, that is, the ability to adapt system operation before, during or after some change or disorder in order to maintain expected operations, under expected and unexpected contexts. The objective of this study is to propose indicators of resilience that aim to help manage the main contingencies experienced by the CCO, increasing the operational capacity of the planned operations, even in the face of unexpected situations. This research presents a single case study of a regular air transport company that operates around 800 daily flights throughout Brazil and in some international destinations. A systemic mapping of the main contingencies experienced by CCO were performed using the Functional Resonance Analysis Method (FRAM). Data was gathered by means of interviews, in locus observations and analysis of technical documents. Two indicators of resilience have been proposed that have the potential to indicate where and when the system defenses should concentrate their efforts in order to avoid contingencies. The use of FRAM and the principles of Resilience Engineering (ER) have shown promise for the identification of resilience indicators, and the proposed method may be used in future research that seeks to identify indicators of resilience in complex sociotechnical systems. / Um dos principais desafios organizacionais de empresas a?reas ? manter a continuidade de suas opera??es, contornando problemas que envolvem o fechamento de aeroportos, quest?es de infraestrutura e eventos de manuten??o n?o programados. Para lidar com estas conting?ncias, as empresas utilizam Centros de Controle de Opera??es (CCOs), cuja responsabilidade envolve organizar e acompanhar a execu??o do planejamento de suas programa??es de voo, ao mesmo tempo em que tentam acomodar a variabilidade encontrada. Este tipo de atividade cria a necessidade de o sistema ser resiliente, isto ?, a capacidade de adaptar o funcionamento do sistema antes, durante ou ap?s alguma mudan?a ou desordem, a fim de manter as opera??es previstas, sob contextos esperados e inesperados. O objetivo desta pesquisa ? propor indicadores de resili?ncia que visam auxiliar a gest?o das principais conting?ncias vivenciadas pelo CCO, aumentando a capacidade de funcionamento das opera??es previstas, ainda que diante de situa??es inesperadas. Esta pesquisa apresenta um estudo de caso ?nico de uma empresa de transporte a?reo regular que opera em torno de 800 voos di?rios em todo Brasil e em alguns destinos internacionais. Um mapeamento sist?mico das principais conting?ncias vivenciadas pelo CCO foi realizado utilizando o M?todo de An?lise de Resson?ncia Funcional (FRAM). Os dados foram coletados por meio de entrevistas, observa??es diretas e an?lises de documentos t?cnicos. Foram propostos dois indicadores de resili?ncia que possuem potencial para indicar onde e quando as defesas do sistema devem concentrar seus esfor?os com a finalidade de evitar conting?ncias. A utiliza??o do FRAM e dos princ?pios da Engenharia de Resili?ncia (ER) mostraram-se promissores para a identifica??o de indicadores de resili?ncia, podendo o m?todo proposto ser utilizado em pesquisas futuras que buscam identificar indicadores de resili?ncia em sistemas sociot?cnicos complexos.
