This problem is usually tackled by governmental agencies by having officials to pore over companies' financial data and to single out those that exhibit fraudulent behavior. Such work tends to be slow-paced and tedious. This paper proposes a machine learning-based system capable of classifying whether a company is likely to be involved in fraud or not. Based on financial and tax data from various companies, four different classifiers – k-Nearest Neighbors, Random Forest, Support Vector Machine (SVM), and a Neural Network – were trained and then used to indicate fraud. The best-performing model achieved a macro-averaged F1-score of 92.98% with the Random Forest.

A questao central e verificar se as instituicoes conseguem executar os CT-INFRAs no prazo acordado com a FINEP. O estudo foi realizado na UFES. O ponto de partida foi questionar a FINEP, via portal de informacao, dados de todas as instituicoes que participaram dos convenios no referido periodo. Tais dados foram referentes ao prazo de execucao do convenio, tempo destinado para liberar a segunda parcela e porcentagem gasta do valor total. Ao se comparar os dados, chegou-se a conclusao que raramente uma instituicao consegue executar os convenios no prazo acordado de tres anos. Alem disso, foram aplicados questionarios junto aos coordenadores de projetos, a FINEP, a Prefeitura Universitaria (PU) e a Fundacao Espirito Santense de Tecnolo...

Its composition obeys the Law 5.540/1968, which determines that 70% of its members must belong to the faculty, fact that tends to lead to disparities between the political strength of the teaching category and the category of technical and administrative educational employees, a factor that has the potential to destabilize democratically decisions issued by the Council. In order to mitigate such differences, points up the implementation of administrative transparency tools, to provide social audits and expand democratic balance of forces between the categories, in allusion to the Jürgen Habermas’ “Discourse Theory”. The theory proclaims that the participation of the collective within the government produces better reasoned speeches, more debated and democratically more embracing, and argues that the deliberative participation must be performed by institution...
