[pt] A partir de uma perspectiva sociointeracional de análise de uma atividade de fala, este trabalho busca investigar através de um mapeamento temático e interacional, como analistas de investimento e executivos gerenciam a produção das as perguntas e respostas para atingir seus objetivos comunicativos e que fatores orientam a produção dos participantes. O corpus é constituído de earnings conferece calls de três companhias de capital aberto brasileiras, acessadas via Internet. A análise considera os efeitos que a mediação tecnológica tem sobre a estrutura de participação; a influência dos papeis institucionais, das diferentes especialidades e do alinhamento de múltiplos objetivos, na interpretação dada pelos executivos às perguntas e suas estratégias argumentativas; e nas habilidades comunicativas de analistas e executivos para lidar com as especificidades das relações de poder e do objetivo fim do evento: a segurança nas decisões de investimento por peritos e leigos. / [en] This work uses a social-interactional and activity based framework to investigate through thematic and interactional mapping how equity analysts and CEOs manage the production of questions and answers to achieve multiple communicative purposes and which factors orient participant production in earnings conference calls of three publicly traded Brazilian companies accessed via the Internet. The analysis considers the effects of technological mediation on participant structure; and the influence of roles-relational, expert orientation and agenda alignment on the interpretation of questions made by executive and their argumentative strategies; and on executive and analyst communicative ability to deal with power play features and activity ends-objectives: safe investment decisions by expert and lay players.

The Truth and Reconciliation Commissions (TRC) outlined 94 Calls to Action (CTA) that are essential to address reconciliation in Canada (TRC, 2015). Five (Calls 87-91) of those CTA were related to sport. One of those Calls, Call 90, emphasized the need for national sport organizations (NSOs) in Canada to create inclusive policies and programming with an emphasis on anti-racism awareness and training. Similarly, safe sport in Canada was created as an initiative to address maltreatment, discrimination, and harassment in sport. In 2019, the federal government mandated NSOs to create safe sport policies and programming. However, there has been no such mandate to implement the TRC's CTA. The TRC's CTA 90 and safe sport have been treated as separate issues and there has been no effort to see how these two initiatives could inform each other. Through the use of Bacchi's (2012) "What's the Problem Represented to be" approach and applying a settler colonial lens to my analysis, I investigated how NSO staff and safe sport policymakers are constructing safe sport in Canada and if that included addressing anti-Indigenous racism. Through 10 semi-structured interviews from participants representing a total of eight NSOs as well as archival research of safe sport and equity, diversity, and inclusion policies, I found that the participants and the policies produced three discourses: 1) Anti-Indigenous racism does not require a separate policy; 2) policies alone are insufficient: Safe sport education and resources are needed to address anti-Indigenous racism; 3) the TRC's CTA are not being treated as a priority by Sport Canada but NSOs want to act in consultation with Indigenous organizations. These discourses provide insights into how NSOs are constructing safe sport in Canada, leaving anti-Indigenous racism unproblematized, and thus furthering settler colonialism.

In many outage management systems, customer trouble calls have been used as the primary source of outages for distribution level outages. However the information from the trouble calls is not completely reliable as they lead to problems like okay-on-arrival reports, over escalation and extended outage times for the customers. But with the recent developments in communication and information technologies, utilities started to adopt Automated Meter Reading systems for their operational needs. In this thesis, an algorithm is developed and implemented that makes efficient use information available from the customers and powerline communication based AMR systems for outages. The work has taken advantage of the polling feature of powerline based AMR systems to identify the scope of the outage. The polling procedure uses the on demand read feature of the AMR systems that allows the utility to communicate directly with the customers. The meters in the neighborhood of the trouble calls are polled to identify the affected customers and the outages are located by back tracking to common point. In the first part of the algorithm, the distribution system is modeled as a tree and the meters are strategically polled based on the customers reporting the outages. The outage areas are identified and escalated to find the actual outage location. The crew can be directed to the outage scene to fix the cause of the outage. The algorithm discusses the rules to identify single outages, single customer outages and multiple outages. The algorithm was tested on different test systems representing distribution systems of various sizes. The algorithm is tested for different outage scenarios for all the test cases.
