Uso de variáveis relacionadas com a produção embrionária, em camundongos, como fatores preditivos

Mouse embryo production by superstimulation is a multifactorial process. To minimize the number of sacrificed animals and to maximize the results of the superstimulatory treatment, it should be possible to predict the risk of do not get embryos from such a treated animal. This work aimed to evaluate if the variables - hormone concentration and the timing of its administration, the copulatory plug presence and individual male used to mating – could be predictive factors on the mouse embryo production. Females were distributed in four groups (cross-over design) related to scheduled superstimulation treatment (1300h or 1700h) and eCG/hCG administered concentration (5 or 10IU). After the hCG treatment, females were put to mate. On the next morning it was verified the presence of a copulatory plug (D0.5). Embryo recovery was performed from D2.5 to D4.5 by flushing the oviducts and uterine horns. Total structures recovered (TSR) and the viable embryos (VE) were classified by its morphology. Viability rate (VR) was calculated with VE in relation to TSR (x100). Group comparison was analyzed with 5% of significance. There were no significant differences among groups, even when only main effects were analyzed (hormone concentration and timing of its administration). There was significant difference in VR from animals with or without plug and from the worst and best males used. It was concluded that neither the hormone concentration nor timing of its administration - or their association – was significant as predictive factors for the embryo production. However, the plug presence was related to higher VR.

Organizações estratégicas: campo de (re)produção da ideologia narcisista e do espetáculo

This paper aims to present a reflection on the contemporary way of life substantiated by its pillars -consumption, individualism, competitiveness, fluid relationship - aiming to assimilate it to an administrative management model that is widely distributed in monopolistic-financial capitalism - strategic management model - guided by the question: Why does this management model find such a fertile field for development in the contemporary scenario? Thus, the study was theoretically and methodologically based on the approach of psychosociology and was developed from a theoretical review. We have conducted a contextualization and definition of contemporaneity in which a market society that celebrates the spectacle lies, analyzing, from this point, the strategic organizational management model that has been working as a drug in the subjective constitution of the individuals producing the striking resonances in the psychosocial field. The assimilation performed in this paper allowed us to clarify some possible causes of social pathologies arising from the increasingly cruel world we face in professional life.

Produção científica sobre gestão de recursos humanos e sustentabilidade: síntese e agenda de pesquisa

This study aimed to verify the existence of articles on human resource management and sustainability in the major journals in the administration area in Brazil. Were selected for the study 24 national journals Qualis A1 to B3. The results indicated that the interaction between these two areas is recent in Brazil, since the first publications appeared only in 2006, and found 170 articles that investigated the human resource management only nine established relationship with sustainability.
