Portugal, província do Brasil? O policentrismo do império híbrido luso-brasileiro. Especificidades históricas
In 1808, the Portuguese royal family arrived in Brazil, fleeing the Napoleonic invasions of Portugal. From then on, an entire political-administrative structure was created in the colony that transformed Rio de Janeiro into the new capital of the Portuguese overseas empire. This article addresses issues of political identity in this Portuguese empire from 1808 to 1822. It seeks to demonstrate, through sources, historiographical debate and valuing…
Psychosocial and behavioral outcomes in the adult workforce during the Covid-19 pandemic: A 1-Year longitudinal survey
Relative to pre-pandemic, poorer psychosocial outcomes and worsened health behaviors were observed across all time points, with values worse at the baseline and 12-month time points when COVID-19 surges were highest. While COVID-19 prevention behaviors were consistently deemed to be important by employees, the psychosocial outcome and health behavior data suggest the potential for harmful long-term effects of the pandemic on the well-being of non…
