A flood of ideas and proposals on the shape and selection of Sustainable Development Goals (SDGs) has begun to rise since 2012. This article looks at some of them, trying to understand which kind of -boundary work‖ between science and policy is done here. Starting with a reflection on the epistemological and practical implications of -discussing SDGs‖, it primarily addresses scientists, but also decision makers and activists interested in the post-2015 debate. In practical terms of SDG selection, the argument goes in favor of a self-reflective -politization of science‖; i.e., against claims for broad scientific comprehensiveness of SDGs and in favor of an -exemplary‖ selection of thematic areas and targets, which would combine aspects of (i) political opportunity and (ii) societal visibility. These criteria are only very partially met in the proposals the article looks at. By applying them, the article emphasizes the political importance of addressing, through SDGs, the subnational level directly, thus making the case for an SDG on cities. Such an SDG should, by the same logic, be rather focused and exemplary than all-encompassing. The recently employed formula of -resilient, inclusive and connected cities‖ is considered useful, when accompanied by tangible and communicable indicators.

SUMMARY.We evaluated the incidence of anti-Dengue virus (DENV) antibodies and dengue viremia in a region of Mexico with a high prevalence of dengue. DENV is the most important arthropod-borne virus in terms of human morbidity and mortality in America We tested 800 blood donors from a tertiary care teaching hospital that provides care in Northeast Mexico, to identify anti-DENV IgM and IgG antibodies by enzyme-linked immunosorbent assay (ELISA) and DENV genome by reverse transcription polymerase chain reaction (RT-PCR). In addition, routine tests for donors including Brucella, Hepatitis C virus (HCV), Venereal Disease Research Laboratory (VDRL), HIV-1 and HBsAg identification were performed. We found that 59% of donors were reactive for anti-DENV IgG and none of them had reported recent DENV infection; however, 16 (2%) were reactive for anti-DENV IgM antibodies. None of them were viremic at the time of donation. Routine tests showed that the prevalence of anti-Brucella was 0.71%, anti-HCV 0.71%, anti-HIV-1-2 0.14%, HBsAg 0.14% and VDRL test 0.57%. Although DENV transmission by blood transfusion had not been confirmed in Mexico, the finding of a high prevalence of anti-DENV IgM-positive donors with asymptomatic manifestations and the recent viremia reported in blood donors suggests that this route of transmission might be possible.

This article analyses the narratives of impact-driven transition research in the field of sustainability studies. It reconstructs patterns of narrations at a discourse level. Departing from the understanding that narrating is a fundamental mode of communication and education, this contribution is ultimately driven by the commitment to understand how narrativity can be improved in order to reach more effective rhetoric for sustainability research. The article starts by describing the dilemma sustainability researchers might find themselves in regarding their position vis-à-vis society and politics. This dilemma seems to shape the narratives researchers use for describing their work. After conceptualizing narratives on a structural level, findings from a comprehensive qualitative interview study are presented and discussed. We find that sustainability researchers can be clustered in five different types, depending on their affinity or distance to real-world sustainability processes, their propensity to either incremental reforms or transformative change and the relationship between environmental and social concerns in the context of the sustainability concept. Furthermore, we find that critical-constructive transformative research encounters challenges when narrating about its position vis-à-vis society and policy-making in the process of formulating goals and working towards them. We identified a tension between leaning stronger either towards independent, critical goal formulation or towards an engagement with actual political processes. Maintaining the ability to change roles between the process-involved and the process-observing sustainability researcher might be a promising way out for those dedicated to workings towards sustainability transitions.
