RESUMO
In December 2019, coronavirus disease (COVID-19) was detected in Wuhan, China. Due to the rapid spread of the disease, containment measures were adopted, which caused unprecedent shifts in individual mobility. Although some studies explored the impacts of the COVID-19 pandemic on travel patterns and resilience of transport systems based on different analysis techniques, there is a lack of studies addressing the impacts of the pandemic on the sustainability and resilience of urban mobility systems using in-depth and holistic methods, such as system dynamics. This research aims to characterize the dynamics present in urban mobility systems when exposed to pandemics and analyze the changes needed for systems to increase their resilience to pandemics using qualitative system dynamics modeling. The framework comprises the characterization of cause-and-effect relationships and the creation of systems' causal loop diagrams (CLD) in their basic state of functionality, when affected by pandemics, and still operating owing to its resilience. Our findings indicated that the CLD of a resilient system is driven by strategic preparedness and response plans, as well as research and development, which balance the spread of the pandemic and increase support on technological strengths and the activities performed from home.
RESUMO
This paper presents part of the findings of a doctoral study aiming to understand the construction of informational strategies for living and dealing with Prostate Cancer related information according to self-reported levels of functional health literacy. A qualitative modeling design framed the inquiry through the constructivist perspective. Older men recreate modes of living and attitudes toward information according to their social and cultural capital, as well as the intensity of their contact with an informational network. Self-reported levels of functional health literacy seem to be harmonious with distinct informational profiles/patterns despite differences in general literacy or formal education. This study implies a new understanding of functional health literacy and its role, the dynamics of social/informational networks, as well as the needs of redesigning communication strategies.
