Examining the generalizability of research findings from archival data

This initiative examined systematically the extent to which a large set of archival research findings generalizes across contexts. We repeated the key analyses for 29 original strategic management effects in the same context (direct reproduction) as well as in 52 novel time periods and geographies; 45% of the reproductions returned results matching the original reports together with 55% of tests in different spans of years and 40% of tests in novel geographies. Some original findings were associated with multiple new tests. Reproducibility was the best predictor of generalizability—for the findings that proved directly reproducible, 84% emerged in other available time periods and 57% emerged in other geographies. Overall, only limited empirical evidence emerged for context sensitivity. In a forecasting survey, independent scientists were able to anticipate which effects would find support in tests in new samples

Family horticulture as precursory activity for social developemnt: social structure and soil analysis for a sustainable production

The objective of this work is to present orchard planning in peri-urban soils of Escobar (Buenos Aires province), in the framework of the Phase 3 Orchards Project of the NGO A Roof for my Country. Feminization of agriculture is displayed after studying growers profile. Growersaresensitized by the needto consider the qualityof the soil, and the need forsoil analysisof theirsmall farmsto detectlimiting factors andthe risk of pollutants enteringthetrophicchain. Routine analysis were performed to evaluate the productive conditions, and heavy metals Cd, Cr, Cu, Ni, Pb and Zn were also analyzed, as they may be hazardous for human health. Soil analysis showed appropiate fertility conditions, but producers should take into account other limiting factors related to their precarious accomodation. Soil average and maximum contents of heavy metals resulted acceptable as stipulated by the argentine and international guidelines.Fil: Giuffre, Lidia. Universidad de Buenos Aires.
