Perfluoroalkyl substances in Arctic birds por Axelson, Siri

“…This might be due to the fact that PFAS typically accumulate in protein-rich tissues with high blood content, and that the liver has a detoxifying function and takes care of the contaminants in the body. As PFASs are produced in industrial areas far away from Svalbard, the detected concentration levels in the studied species give reason to further investigate the fate and transport of PFASs, as well as their effects on wildlife in the Arctic region.…”

Designing methods for the monitoring and evaluation of household food security in IFAD-funded rural development projects: Technical Guide: Strengthening the Household Food Security... por Carletto, Calogero, Morris, Saul Sutkover

“…The importance of a joint temporal and cross-sectional comparison of the beneficiary group against a counterfactual is crucial to simultaneously control for the effects of all sorts of external factors likely to contaminate the impact evaluation results. We also argue that the involvement of the evaluation team in the earliest stages of project design stage is the most suitable way to ensure a proper and accurate evaluation without having to rely on more complicated statistical techniques, as well as to permit a sound learning process to ensue from the evaluation exercise. …”
