El presente estudio caso-controle, doble ciego, y prospectivo investigó los efectos del entrenamiento musical de numerosidad (NMT; Numeracy Musical Training), sobre habilidades cognitivas en niños de enseñanza primaria. Participaron 42 niños de 8 a 10 años divididos en dos grupos: con Bajo Rendimiento Aritmético (n = 21), y con Medio Rendimiento Aritmético (n = 21). Los niños pasaron por dos evaluaciones, antes y después de la realización del NMT, en las cuales se aplicaron pruebas cognitivas y escalas de comportamiento, que evaluaban variables tales como: rendimiento escolar, CI, memoria operativa, cognición numérica, ansiedad y estrés. El NMT fue desarrollado en ocho sesiones colectivas y tuvo como objetivo estimular los sistemas de la cognición numérica e integrar conocimientos musicales básicos y representaciones simbólicas. Después de la intervención por medio del entrenamiento musical los niños de ambos grupos obtuvieron mejoras significativas en el rendimiento académico, en los sistemas de la cognición numérica y en la memoria operativa, así como una disminución de la manifestación de ansiedad a las matemáticas. The present case-control, double-blind, and prospective study investigated the effects of Numeracy Music Training (NMT) on cognitive skills of primary school children. Participating in the study were 42 children aged 8 to 10 years divided into two groups: Low Achievement in Math (n = 21), and Average Achievement in Math (n = 21). The children underwent two evaluations before and after NMT, where cognitive tests and behavior scales were applied that assessed variables such as school performance, IQ, working memory, numerical cognition, anxiety and stress. NMT was developed in eight group sessions and aimed to stimulate the systems of numerical cognition and integrate basic musical knowledge, and symbolic representations. After the intervention, through musical training, the children in both groups showed significant improvements in school performance, systems of numerical cognition and working memory, as well as the reduction of manifestation of mathematics anxiety.

This research aimed to explore the relationship between employees' perceptions of organizational politics (POPS) and their predisposition to involve in knowledge sharing (KS) behaviors at individuals and workgroups level in the Brazilian automotive Modular Consortium. The sample included 144 shop floor employees of Modular Consortium (six connected companies in assembly lines). The POPS-KS relationship was analyzed using different referents, seeking to understand how individuals and groups respond to the presence of organizational politics, and POPS and KS were tested in a Brazilian context, shedding new light on potential cultural influences impacting this relationship. The results evidenced that positive interpersonal communication can contribute to KS, and in turn, KS can counteract the negative impacts of POPS. There was a positive relationship between POPS-KS, indicating that POPS may have functional effects in facilitating KS of individuals and workgroups. Key findings and implications for future research were discussed.

The purpose of this paper is to analyze the relation between Organizational Climate and Knowledge Management in the shop floor. The study is conducted in an auto part plant inserted in a Truck Factory with 7 partners. 44 blue collar workers were interviewed. The results show a relationship between Organizational Climate and Knowledge Management in the automotive sector, evidenced by the significant correlations between the variables analyzed. The unemployment situation can negatively influence the climate of organizations. The positive social interaction can preserve knowledge sharing even when there are weaknesses in the organizational climate. Future research can compare the results of this study with another sample in the same environment in stable employment situation. Other research may replicate this study with a larger number of participants.
