Is the qualitative approach applicable to medical education and research?

The first issue of 2017 of Ciência & Saúde Coletiva presents the difficulties of medical researchers to adhere to qualitative research, on the one hand; on the other, it brings a series of articles, originating from empirical research or review in which these professionals appear as first authors or as member of research groups. The key question is: Why is that in the exercise of an essentially humanistic and intersubjective activity are there strong resistances to knowing and recognizing the scientificity of the qualitative method.

Biofouling successional processes

To assess the successional pattern of fouling organisms we tested the hypothesis that depth, light intensity and predation influences the trajectory of the fouling community. The results suggest that each physical factor or biological process can change the successional trajectory, and the respective model (e.g., convergent, divergent, parallel, or cyclic) depends on the magnitudes of the determinants that act on the community at each stage of its trajectory.

Study shows vulnerabilities of GPS-dependent systems to electromagnetic attacks

The study identifies the levels of jamming power and distance required to disable GPS-dependent systems such as cell phones, and those used in automotive and aeronautical applications. Open source software was used to analyze the data collected to identify vulnerabilities in these systems, as well as proper countermeasures to undertake. The results were published by the research team from the Brazilian Aeronautical Institute of Technology in the Journal of Aerospace Technology and Management. Read More →
