The Influence of Gender and Facial Appearance on Voting Practices

Women’s faces tend to naturally retain more neonate features than men. These features, such as a greater eye height, a smaller nose area, and a wider smile, would cause women to have more immature faces than males. Interestingly, women who have these facial features are often perceived as more attractive than women with mature facial features. These findings imply that women would be judged less competent than men, and that immature-faced women would be perceived as less competent and more attractive than mature-faced females. Given the direction of political leadership in our country, this has interesting implications for females that are vying for leadership positions. Thus, our study examined the effects of both candidate gender and facial features on voting likelihood, and perceptions of attractiveness and competence, by pairing pictures with neutral party platforms.

A new playing field: retrospective voting and soccer in Brazil

O propósito deste estudo é analisar o possível impacto que um viés emocional possa ter nos julgamentos dos eleitores. Nesse sentido utilizamos o futebol como fonte exógena de um choque. O nosso modelo de efeitos fixos nos leva a concluir que vitórias de equipes no final de semana da eleição estão associadas a maior votação no incumbente indicando que um viés emocional pode influenciar o eleitor.

Automatic Classification of Three-Phase Flow Patterns of Heavy Oil in a Horizontal Pipe Using Support Vector Machines

The pipe flow of a viscous-oil-gas-water mixture such as that involved in heavy oil production is a rather complex thereto-fluid dynamical problem. Considering the complexity of three-phase flow, it is of fundamental importance the introduction of a flow pattern classification tool to obtain useful information about the flow structure. Flow patterns are important because they indicate the degree of mixing during flow and the spatial distribution of phases. In particular, the pressure drop and temperature evolution along the pipe is highly dependent on the spatial configuration of the phases. In this work we investigate the three-phase water-assisted flow patterns, i.e. those configurations where water is injected in order to reduce friction caused by the viscous oil. Phase flow rates and pressure drop data from previous laboratory experiments in a horizontal pipe are used for flow pattern identification by means of the 'support vector machine' technique (SVM).

The thrust and the relation factor kr in linear induction machines

This paper shows a new manner to establish the thrust of a linear induction machine. A new factor is established, named ''Relation Factor, which provides conditions to establish the thrust and other important variables of the linear and sector induction machines.
