The Brazilian northeast has a characteristic relationship with water resources because, in this region, water scarcity is associated with natural factors and accentuated by anthropic actions that interfere with water quality. The present work aimed to perform a temporal analysis of the water quality of the Nilo Coelho reservoir, municipality of Terra Nova, a semi-arid region of Pernambuco. Initially, the parameters of dissolved oxygen, nitrate, and phosphorus, available in the system of hydrological response units for Pernambuco (SUPer), following the resolution of the National Environment Council (CONAMA), for the years 1963–2021, were analyzed. Subsequently, land use and occupation mapping were carried out to identify the activities that developed in the region. The result of the analysis of water quality for the Nilo Coelho reservoir classifies it as little compromised, since the parameters are within acceptable limits, with greater variations for phosphorus. Regarding the use and occupation of the soil, there was an increase in water availability and agricultural areas, with a reduction in the caatinga. Continuous monitoring of water quality in the reservoir is recommended, in addition to the application of SUPer and land use and occupation maps as tools for the management of water resources.

The Natural Monument of São Francisco (MONA) is one of the Conservation Units (UCs) in Brazil. The creation of a CU can affect mostly traditional fishermen. In this context, the management council of this Conservation Unit is a collegiate body where the presence of fishermen is essential. This research aims to analyze the participation of traditional fishermen in the Consultative Council of the Natural Monument of the São Francisco (CCMNRSF), measure the level of participation of traditional fishermen in the CCMNRSF and identify the factors that hinder or favor this participation. In addition to the decree that creates the MONA, the ordinance that creates the CCMNRSF, were left as minutes of the meetings of the CCMNRSF. The traditional fishermen have 13% of the seats reserved in the CCMNRSF, with representatives in all the CCMNRSF meetings, but in only one third of the meetings the speeches of these representatives were recorded. some factors favor the participation of artisanal fishermen, including the decentralizing nature of ICMBio. It was also observed that the absence of peers hinders participation in the CCMNRSF, in meeting the demands made by workers.

Este trabalho explora a utilização de redes neurais artificiais auto-organizáveis (modelo de Kohonen) para a classificação de perfis profissionais, agrupando-os por áreas de atuação, com a finalidade de auxiliar no processo de triagem de candidatos, na área de Recursos Humanos (RH). O resultado prático dessa implementação é viável para a área de RH, tendo em vista que as redes neurais têm a capacidade de lidar com dados imprecisos, incompletos ou totalmente novos, adaptando-se rapidamente a eles.

Este estudo considera empiricamente a variação linguística no uso da concordância verbal (CV) na terceira pessoa do plural ou P6, buscando aferir, pela observação do desempenho linguístico de falantes do português popular de Vitória da Conquista - BA, se a aplicação da regra de concordância constitui um fenômeno de variação estável ou mudança em curso. Tomando o corpus do PPVC - Português Popular de Vitória da Conquista, foram analisados alguns grupos de variáveis linguísticas e sociais objetivando mensurar quais fatores estariam condicionando o índice de 17,2% de aplicação da CV em P6 pelos indivíduos desta comunidade.PALAVRAS-CHAVE: Sociolinguística.
