Item Identificação de Outliers para detectar riscos de gestão(2018-08-17) Brizeno, Raissa Costa; Monteiro, Cleviton Vinicius Fonsêca; Lima, Rinaldo José de; http://lattes.cnpq.br/7645118086647340; http://lattes.cnpq.br/9362573782715504; http://lattes.cnpq.br/1672154276438369Outliers are values that doesn’t converge with the rest of the data series. These values when they arise in financial context can represent problems that have a direct influence on the health of an enterprise and the decision-making by the managers. In view of this, it was intended with this work identify anomalies in financial launches arising from the accounts of real companies. For this, statistical analyzes of the launches were fulfilled in order that outliers detection techniques could be chosen and then compared with the outliers detection of evaluators . Among the great variety of techniques were chosen the methods of Boxplot, Boxplot adjusted, MAD and standard deviation. The results show that most of the series didn’t follow a normal distribution, and the experimental results of the comparisons between the automatic methods and the evaluators showed substantial differences.Item Uma metodologia para suporte à tomada de decisão quanto ao uso de blockchain na área de registros públicos(2021-02-11) Silva, Saulo Gomes da; Lins, Fernando Antonio Aires; http://lattes.cnpq.br/2475965771605110; http://lattes.cnpq.br/7125624100024345The emergence of Bitcoin and Blockchain technology has changed the world of ecommerce. These technologies have the potential to one day become the standard for Web applications, through decentralized applications. Decentralized applications are flexible, transparent, distributed, resilient applications and have greater growth power, in terms of scalability and availability, when compared to the current software model (clientserver architecture). There are limitations that prevent the use of Blockchain technology for solving problems involving data and information distribution. Because there are limitations, designers and enthusiasts who are not well educated about the technology can make mistakes and use it in a way that damages the solution to which it belongs, in addition to preventing it from reaching its fullness. Due to the possibilities that Blockchain technology and decentralized applications bring, this work aims to design a methodology to assist in decision making regarding the use of Blockchain for the government environment, specifically in the area of public records. To exemplify the application of the methodology, a case study was carried out using the service of registration and consultation of registries in notaries, which service is supported by a system provided by the National Council of Justice. As a result, it was possible to demonstrate that the methodology process creates an implementation profile for Blockchain technology, a profile that allows the system designer to choose and configure Blockchain platforms for the desired purpose. The process result indicates that the Blockchain technology is suitable for the purpose of notary service, ensuring the proper use of technology and avoiding possible losses.Item Gestão democrática e conselho escolar: a participação da comunidade nos processos de decisão numa escola municipal de Olinda – PE(2019-11-28) Tavares, Ana Paula; Ferraz, Bruna Tarcília; http://lattes.cnpq.br/2100573722828366; http://lattes.cnpq.br/4960364653386296This research is the result of an investigative process carried out on a Olinda’s (PE) municipal school. The purpose of this research was to analyze the community participation in the School Council (SC), identifying its influence on the processes of decision of the current school management. Based on the assumptions of the Case Study of descriptive and interpretive aim, the study was carried out by way of a systematic observation of the SC’s meetings and of the semi-structured interviews with the representatives of each active segment. It was sought to comprehend the meanings and the importance that the counselors attribute to the SC’s role as a space for the effective participation in the configuration of the processes of democratization of the management and of the school. To analyze the data, it was chosen the methodology of Content Analysis, that made it possible to identify the conceptions of management and participation, as well as the spaces and the forms of participation and decision of the interviewed representatives, contributions and influences on decisions in the school management. The results indicate that the conceptions of management and participation present among the members of the observed SC are close to the socio-critical perspective of school management, wich foresees the participation of all involved in the formal and non-formal spaces of the SC. It was possible to verify the knowledge level of the educative community about the function, limits and possibilities of the counselors proceeding in this decision-making instance. However, despite the legal advances and the participatory practices in management decentralization processes, there was a need for training of the counselors to better understand the effective political participation among representatives and the SC’s strengthening.Item Ancoragem de preço: uma investigação econômico-comportamental sobre efeito ancoragem no uso do aplicativo menor preço em Pernambuco(2019) Silva, Gabriel Fernando Candido da; Maia Filho, Luiz Flávio Arreguy; http://lattes.cnpq.br/2508376486299377; http://lattes.cnpq.br/5814642766143449
