ABSTRACT. This

PurposeThe objective of this study is to identify research gaps related to skills required for Industry 4.0, considering research in the context of Brazilian undergraduate courses. In this sense, the question of this study was established: What are the educational gaps related to skills required in Industry 4.0 context, considering considering research in the previously mentioned?Design/methodology/approachTo answer this question, the ten top work-related skills required for professionals in Industry 4.0 published by the World Economic Forum were used to perform a systematic literature review. From this review, 100 articles were found in the searched databases. From them, 18 were within the research scope.FindingsThrough an analysis of their content, it was possible to verify that, from the 10 skills analyzed, only six were identified in the articles. That is, no research was found for: people management, service orientation, negotiation, and cognitive flexibility. Additionally, there are undergraduate courses that are not considered in current researches and should be analyzed.Originality/valueThe gaps pointed out in this study are relevant to guide future analyzes of the Brazilian educational model and may provide insights for research in other countries.

The Mid-Atlantic Ridge at 45øN has a ridge crest depth close to normal for slow spreading ridges and a crustal thickness of 6 km. However, the free-air gravity over the region is higher than expected for such axial depths, and erupted basalts are enriched in incompatible trace elements and radiogenic isotopes, which could be taken to indicate the presence of a mantle plume beneath the spreading axis. But the ridge is at normal depths and the crust is of normal thickness. We model free-air gravity across and parallel to the strike of the ridge. A density structure derived from a cooling model provides a good fit for gravity across the ridge axis. A gravity model along the ridge axis indicates that most of the gravity signal over the Azores and Reykjanes Ridge is related to thicker crust, while the gravity signal over 45øN can be modeled by a density anomaly, which extends along the spreading axis from about 43øN to 50øN and from zero age to 35 m.y. Such a mass excess can be explained by an increase in the garnet content of the mantle within the stability field of garnet peridotite. The enriched basalts occur in the same region as the mass anomaly. We interpret them as originating from cool hotspot mantle. This anomalous mantle may derive from a hotspot that existed at the North America-Africa-Eurasia triple junction when it was at 45øN between 59 and 26 m.y. The King's Trough Complex is the remnant of that hotspot. We consider that this cool hotspot mantle still underlies the spreading axis and contributes to crustal construction.
