Múltiplos fluxos ópticos e o processamento atentivo da informação visual

The environment in which we live in, we constantly deal with a huge amount of dynamic information, thus, attention is an indispensable cognitive resource that allows an effective selection of stimuli for our survival. From this, investigating how we process our encouragement in movements and how the attention spreads into a space to serve more than one stimuli simultanously is something very important. The behavioural urgence hipothesis suggests that the encouragement in a movement of approaching shows a certain priority in the process related to objects which are in a movement away, but there are researches that point out that it might not happen in an attentive phase, but instead as a priorization of motor response. There are also many controversies found in researches about attentive focalization, in which some studies suggest that the focus of attention would work in a similar manner to a zoom lens, while some searches indicate that the focus of attention could be shared to answer some stimuli in non contiguous regions. This study tried to investigate through two experiments the effect of attentive priorization by encouragement in movements and how the attention is spread with distractors stimuli. The first experiment investigated if the amount of moving flows really influenced in the process of information. The results indicate an effect of priorization of the flows guided in relation to aleatory ones and also from the unique flow due to dual flow. The second experiment investigated how the distribution of attention is in a space with the use of flows as an exogenous cue. The results indicate that the focus of attention works as the one suggested in the zoom lens model.

Internacionalização de empresas e o fechamento do capital : um estudo sobre a deslistagem no mercado brasileiro

This work contributes to the finance literature proposing to analyze the relationship between the degree of internationalization of Brazilian companies and the likelihood of delisting. Therefore, even though the internationalization as a differential, in the formulation of hypotheses and analysis of the relationship between the variables dealt with concepts and theories within the Corporate Governance, which is already established in theory when it comes to delisting. First, with a view to the theory of internalization, which gives competitive advantages to the company due the adoption internationalization strategy and in parallel to the positive effects that this strategy generates on firms performance, it was formulated an hypothesis that the degree of internationalization would be adversely related to the probability of delisting, mainly due to such benefits generated to the organization. In turn, as an alternative hypothesis of the research, it proposed a positive relationship between these variables, based on agency theory, according to which internationalization would contribute to delisting by increasing geographical separation between shareholders and managers and, consequently, agency conflicts and the difficulty of monitoring. For the achievement of objectives, as well as being included economic and financial variables and GC, it was proposed the analysis of periods of crisis, as the events of recent past of the Brazilian economy. Starting from a base model initially developed by Pour and Lasfer (2013), which later, the proxies of internationalization and crisis have been added also contemplating adjustments to the Brazilian context. The data collected include the period from 2006 to 2014 and information on active and inactive companies at Bovespa. As results, it was found negative significance between the degree of internationalization and the delisting decision, confirming the first hypothesis of the research and stating that the benefits generated by internationalization in the company generate it spreads and results that reduce the probability of delisting. By analyzing the results of control variables was still possible to observe that, even internationalization reducing the likelihood of delisting, by particular aspects of corporate governance in Brazil, such as the high ownership concentration, the benefits it generates contribute to delisting. Regarding the analysis in crisis, the consequences of the crisis of the US subprime in general market were more relevant that the occurrence of itself, unlike the Brazilian internal crisis of 2014, which was statistically significant for the analyzed event. For future researches it is suggested the expansion of database and individual treatment of the reasons adopted by a company when delisting decision.

A análise de Jean-Jacques Rousseau sobre o Projeto de Paz perpetua do abade de Saint-Pierre

The numerous political theories of the modern time were committed to thesocial-political and economic restructuring of the European States, but parallel to those conceptions emerged proposals of a broader range regarding the concern with the harmony among the States and their respective external safety, that is, they envisioned an International System among the European States. In that purpose, the Project of peace by the abbé de Saint-Pierre which glimpses perpetual peace in Europe under institutionalized conditions in order to legitimate a space that aims at facilitating a unified market among the member States. In this context, the sovereign role stands out, given the fact that he is the mediator between the interests of the State and the objectives proposed by the International System of States. However, according to Jean-Jacques Rousseau’s point of view it is evident that the thought of Saint-Pierre is impregnated by a naivety regarding the sovereigns’ government policy and, moreover, for believing that, mediated by a confederal assembly, the princes would voluntarily agree to be part of this project of perpetual peace. Nevertheless, Rousseau does not consider impossible the realization of this project, however, to achieve peace it is necessary force. Therefore, the comprehension of this debate was only possible guided, mainly, by the analyses of the primary works of such thinkers and the theoretical basis of the experts that is necessary, for instance, Evaldo Becker, Gelson Fonseca Jr., Luiz Felipe de Andrade e Silva Sahd, José Oscar de Almeida Marques, José Benedito de Almeida Jr. who enabled a broad comprehension of the purpose to which we dedicated ourselves in this research, allowing the understanding of thekey concepts elaborated by the Genevan philosopher and the themes that concern the relationship between States.
