Diseño de una rúbrica para evaluar trabajos en grupo: revisión y reflexión
[EN] Rubrics are scoring guides that, when done right, offer teachers some advantages while qualifying. Our experience consisted in elaborate a rubric to evaluate the group work and analyze the qualifications obtained, broken down by sections and compare them with weight given to each section within the rubric. The aim of our study was to analyze whether the rubric used was discriminatory, as well as, to detect strengths and weaknesses in the designed rubric. The results showed a wide range of qualifications once evaluated with our rubric. 80% of rubric featured well-defined descriptors and of the remaining 20%, 10% was evaluated by students and the other 10% was too subjective because eval…
Centenarians, but not octogenarians, up-regulate the expression of microRNAs
Centenarians exhibit extreme longevity and a remarkable compression of morbidity. They have a unique capacity to maintain homeostatic mechanisms. Since small non-coding RNAs (including microRNAs) are implicated in the regulation of gene expression, we hypothesised that longevity of centenarians may reflect alterations in small non-coding RNA expression. We report the first comparison of microRNAs expression profiles in mononuclear cells from centenarians, octogenarians and young individuals resident near Valencia, Spain. Principal Component Analysis of the expression of 15,644 mature microRNAs and, 2,334 snoRNAs and scaRNAs in centenarians revealed a significant overlap with profiles in you…
