Endogenous oxytocin plays an important role in a wide range of human functions including birth, milk ejection during lactation, and facilitation of social interaction. There is increasing evidence that both variations in the oxytocin receptor (OXTR) and concentrations of oxytocin are associated with differences in these functions. The causes for the differences that have been observed in tonic and stimulated oxytocin release remain unclear. Previous reviews have suggested that across the life course, these differences may be due to individual factors, e.g., genetic variation (of the OXTR), age or sex, or be the result of early environmental influences, such as social experiences, stress, or trauma partly by inducing epigenetic changes. This review has three aims. First, we briefly discuss the endogenous oxytocin system, including physiology, development, individual differences, and function. Second, current models describing the relationship between the early life environment and the development of the oxytocin system in humans and animals are discussed. Finally, we describe research designs that can be used to investigate the effects of the early environment on the oxytocin system, identifying specific areas of research that need further attention.

The Knowledge Society passes through a complex, competitive and dynamic world portrayed in technology, globalization, reconfiguration of productive practices, and work flexibility, among other aspects. For survival and development, organizations started to work in networks with a view to co-producing more effective results. However, not all networks produce the expected results. The authors of this study identified in the literature the construct "learning networks", defined as network learning by Louise Knight (2002). 5 stages of corporate maturity of inter-organizational networks, and to evolve between them, multilevel learning, proposed by corporate universities, is necessary. In this sense, corporate universities will contribute to the improvement of multiple actors, stimulating involvement, involvement, learning, production of knowledge, meanings of products, results, and businesses. The article aims to identify a public knowledge gap about the relationship between corporate universities and learning networks for their application in the sector. An exploratory-bibliographic study was carried out based on an integrative review and content analysis. few studies on the relationship between the constructs of corporate universities and learning networks and the application in the sector of collaborative networks and public knowledge, for the creation and learning of organizational learning.
