Challenges for Brazilian MNCs' international human resources management

Multinationals from emerging countries such as Brazil now take the path of internationalisation where early movers have already been. However, these companies have to develop new tools to deal with their own challenges, since they come from countries with different historical backgrounds and specificities. This paper explores challenges for Brazilian MNCs in terms of HRM when operating abroad. It presents the results of six cases of Brazilian MNCs through a grounded theory study. Results show these companies had to deal with their former economic turbulence, shortage of qualified workforce to work internationally and the need to develop HRM competencies to operate globally.

Judiciary as the last resort to protect children and adolescents: intersectoral actions, investment in human resources, and structuring of services

This study aimed to identify the work developed by the Judiciary to prevent sexual violence against children and adolescents within the family. The approach to social representations in a cultural perspective was used. The field study consisted in the 1st and 2nd Court of Crimes against Children and Adolescents, at the State Supreme Court of Pernambuco, Brazil. Participant observation, semi-structured interviews, and focus group with 17 subjects were the techniques for data collection, analyzed through the interpretation of meanings, allowing the identification of the category "The Judiciary as the ultimate level" and the following subcategories: "The public policies to prevent violence" and "The structure and dynamics of Courts". This study allows the visualization of the Judiciary's limitations with regard to the full protection and absolute priority, and that the work along with the victims demands investments in structure and human resources.

Differential expression of the receptor tyrosine kinase EphB4 and its ligand Ephrin-B2 during human placental development

Normal placentation involves the development of an utero-placental circulation following the migration of the extravillous cytotrophoblasts into the decidua and invasion of the spiral arteries, which are thereby transformed into large vessels of low resistance. Given the documented role of the receptor tyrosine kinase EphB4 and its ligand ephrin-B2 in the establishment of the embryonal vascular network, we hypothesized that these molecules are also instrumental in the development of the human placenta. Monitoring the expression during placental development revealed that in first trimester and term placentae both molecules are equally expressed at the RNA level. In contrast, the protein levels were significantly reduced during gestation. Immunohistochemistry revealed a distinct localization of the EphB4 and ephrin-B2 proteins. EphB4 was predominantly expressed in the villous syncytial trophoblast layer and in a subset of intravillous capillaries. Prominent expression was also observed in the extravillous cytotrophoblast giant cells. In contrast, ephrin-B2 expression was detected in the villous cytotrophoblast and syncytial trophoblast cell layers, as well as initially in all intravillous capillaries. Strong expression was also observed in extravillous anchoring cytotrophoblast cells. Hypoxia is a major inducer of placental development. In vitro studies employing trophoblast-derived cell lines revealed that predominantly ephrin-B2 expression is induced by hypoxia, however, in an Hif-1alpha independent manner. These experiments suggest that EphB4 and ephrin-B2 are instrumental in the establishment of a functional placental structure and of the utero-placental circulation.
