    This paper investigates the impact of international sporting and cultural events on national stock markets. We study market reaction to the announcements of the selected country hosting the Summer and Winter Olympic Games, the World Football Cup, the European Football Cup and World and Specialized Exhibitions. We also measure the market effects of the announcement of the nomination of the European Cultural City. First, we evaluate the abnormal returns of winning bidders at (and around) the announcement date using an event study methodology. We study the impact at market and industry-levels. Second, we analyze the determinants of the variation in abnormal returns across events and industries on the basis of a set of variables found important by previous studies and control for the prior probability of observing the event. Third, on the basis of a simple model of partial anticipation, we reexamine the abnormal returns observed for the winning and losing countries and perform a series of tests to disentangle the different theoretical arguments that could account for the observed stock market behavior. Our initial results suggest that the abnormal returns measured at the announcement date and around the event are not consistently different from zero. Further, when we look at particular industries, we find no evidence supporting that industries, that a priori were more likely to extract direct benefits from the event, observe positive significant effects. Yet when we control for the prior expectations, the announcement of these mega-events is associated with a positive market reaction in the nominated country and a negative reaction in the losing country. Overall we interpret our findings as supportive of rational asset pricing and partial anticipation.Market efficiency; Event studies; Mega-events

    O presente estudo teve como alicerce principal a Psicodin芒mica do Trabalho. Atrav茅s da pesquisa explorat贸ria procurou-se responder o seguinte problema de pesquisa: qual o impacto da conclus茫o da gradua莽茫o em funcion谩rios administrativos de uma faculdade particular do DF? Os objetivos espec铆ficos da pesquisa foram: descrever o trabalho prescrito, identificar o trabalho real e analisar sobre a manuten莽茫o desse funcion谩rio. Os dados da pesquisa foram coletados atrav茅s de entrevistas semiestruturadas, realizadas com quatro funcion谩rios da faculdade em quest茫o e posteriormente transcritas e analisadas pela analise de conte煤do. Eles gostam do ambiente de trabalho, valorizam a cultura da empresa, mas est茫o insatisfeitos com a remunera莽茫o salarial que n茫o condiz que o servi莽o real e com a falta de oportunidade de crescimento dentro da empresa

    ABSTRACT. This article sets up a collaborative narrative of three elements from the Group Study on Participatory and Artistic Processes in Research and Education (GEPPAIE), composed of researchers in academic and professional development (professors, doctoral and master's students in Education areas). It begins with a question: how have we experienced, as a higher education study group, our meeting spaces for the production of emancipatory knowledge about research, especially about arts-based research? This question unfolds into others and drives us to what has already been produced collectively, but also boosts the new writings and reflections in this text. It is also part of Ana Serra Rocha's PhD, focused on the problematization of The book鈥檚 experience as a place of epistemological reflection in artistic education, aiming at a broader reflection in the field of artistic education and in doctoral studies. It speculates on the participatory processes of collaborative creation and on some issues that have been debated at GEPPAIE, namely of a relational and methodological nature, with a view to (des/re)construction of knowledge and its forms of written and visual representation.ABSTRACT.

Este art铆culo configura una narrativa colaborativa de tres elementos del Grupo de Estudios en Procesos Art铆sticos y Participativos en Investigaci贸n y Educaci贸n (GEPPAIE), integrado por investigadores en formaci贸n (profesores, estudiantes de doctorado y m谩ster en 谩reas de Educaci贸n).

Esta pregunta se desdobla en otras y es el lema para presentar lo ya producido colectivamente, pero tambi茅n para crear los nuevos escritos y reflexiones que se reflejan en este texto.
