The effectiveness of the parliamentary front on sport in the Brazilian National Congress between the World Cup and the Olympic Games

Parliamentary Fronts (PF) are supra party institutions in the Brazilian National Congress (BNC) that aim to exert political clout in policies regarding a specific subject. Although seldom studied, these institutions have proliferated, and their number peaked in the 54th legislature (2011- 2015) with a tally of 210. In this article, we analyse the effectiveness of the Mixed Parliamentary Front for Sports (FPE), which comprises 198 federal deputies (from 513) and 8 senators (from 81). As method we combined: prosopography of its members; network analysis formed by the decision- making arenas occupied by them at BNC; analysis of their political clout in the legislation for sport. Our results indicate a network mainly comprised of right-wing parties and professional politicians, which suggests a strong potential of political clout. Four theoretical constructs from their profile characteristics were correlated to the centrality within the network, which showed that political expertise and political specialization were crucial factors. We found 8 central members, reinforcing arguments from literature which proposed the existence of an operative nucleus within PF. In relation to the clout in the formulation of sport policy, the representatives belonging to the front were responsible for 94 (61%) proposals of the total of 246 bills presented in the field of sports. Moreover, they are not effective in approving these propositions, although more effective than others PF. Nevertheless, this research gave us a better understanding of policy formulation in complex political arenas, inaugurating a method and a theory to study effectiveness and centrality of this kind of institution

Topological image modification for object detection and topological image processing of skin lesions

We propose a new method based on Topological Data Analysis (TDA) consisting of Topological Image Modification (TIM) and Topological Image Processing (TIP) for object detection. Through this newly introduced method, we artificially destruct irrelevant objects, and construct new objects with known topological properties in irrelevant regions of an image. This ensures that we are able to identify the important objects in relevant regions of the image. We do this by means of persistent homology, which allows us to simultaneously select appropriate thresholds, as well as the objects corresponding to these thresholds, and separate them from the noisy background of an image. This leads to a new image, processed in a completely unsupervised manner, from which one may more efficiently extract important objects. We demonstrate the usefulness of this proposed method for topological image processing through a case-study of unsupervised segmentation of the ISIC 2018 skin lesion images. Code for this project is available on https://bitbucket.org/ghentdatascience/topimgprocess

A method for the continuous monitoring of reactivity in subcritical source-driven systems

The reactivity monitoring in subcritical accelerator-driven systems is a key aspect for the development of this technology. In this work, an inverse method for the determination of the system reactivity from the analysis of flux and power signals, based on the point kinetic approach, is applied to source-driven systems. The features of the algorithm specific to the application to subcritical assemblies are identified, and the sensitivity to the integral parameters characterizing the system is discussed. The technique is applied to different transient situations, simulated by neutronic codes adopting point kinetics and multigroup diffusion, and its accuracy in the presence of localized spatial and spectral phenomena is assessed. Different approaches for the reduction of the uncertainties introduced by the experimental noise are proposed and compared

AmBird: Mediating Intimacy for Long Distance Relationships through an Ambient Awareness System

This paper introduces the AmBird concept that explores how to provide alternatives for mediating intimacy for people that are living apart. The initial design and implementation of the AmBird concept is described as well as a preliminary concept validation. Based on the lessons learned, we highlight the opportunities of AmBird to support multiple intimate acts and our future work.

I Teach You to Quarrel - Empathy and Mediation: Tools for Preventing Bullying

Bullying is a very common, complex and important public health problem among school students. Dovigo describes the school as a place where the conflict can emerge among relational dynamics and involve students, teachers and families. Through the description of an Italian pilot project “Mediamente Bullo,” this chapter examines two tools for preventing bullying: empathy, the ability to share and understand emotional states of others, and mediation, useful to cope interpersonal conflicts. Using the mediation tool, students can learn that many forms of conflicts, including violence, can be solved by identifying the causes, discussing them and practicing nonviolent methods and behaviors. This process helps students to become more aware of positive aspects during the conflict and the power that they have in making important and positive choices. In addition, using the empathy tool, they can better understand the experience of social exclusion. In fact, several studies show that children with higher levels of empathy show less aggressive and more prosocial behaviors and they are more able to regulate their emotions. The goal of this chapter is to provide a contribution about integrated application of two important tools, mediation and empathy, in bullying among school-aged youth for future directions and intervention efforts
