Matrifocalidad y marginación en la periferia de San Cristóbal de las Casas (Chiapas, México)1

The Mexican state of Chiapas —whose troubled sociopolitical and economic situation triggered the 1994 Zapatista uprising— has witnessed a massive displacement of indigenous populations during the last few years. An outcome of regional movement of people has been the appearance of new colonies in the outskirts of the town of San Cristobal de las Casas, especially those formed around the matrifocal family units. For the women in these shanty towns, life in the city has meant loss of family protection, isolation and the development of new survival strategies

Predicting the Affinity of Peptides to Major Histocompatibility Complex Class II by Scoring Molecular Dynamics Simulations.

Predicting the binding affinity of peptides able to interact with major histocompatibility complex (MHC) molecules is a priority for researchers working in the identification of novel vaccines candidates. Most available approaches are based on the analysis of the sequence of peptides of known experimental affinity. However, for MHC class II receptors, these approaches are not very accurate, due to the intrinsic flexibility of the complex. To overcome these limitations, we propose to estimate the binding affinity of peptides bound to an MHC class II by averaging the score of the configurations from finite-temperature molecular dynamics simulations. The score is estimated for 18 different scoring functions, and we explored the optimal manner for combining them. To test the predictions, we considered eight peptides of known binding affinity. We found that six scoring functions correlate with the experimental ranking of the peptides significantly better than the others. We then assessed a set of techniques for combining the scoring functions by linear regression and logistic regression. We obtained a maximum accuracy of 82% for the predicted sign of the binding affinity using a logistic regression with optimized weights. These results are potentially useful to improve the reliability of in silico protocols to design high-affinity binding peptides for MHC class II receptors

A TOOLKIT TO EVALUATE THE IMPACT OF AN EDUCATIONAL ACTION TO SENIORS’ QUALITY OF LIFE

When an institution needs to evaluate the teaching-learning process then it can be done evaluating the knowledge and skills acquired by the learners or by the self-evaluating the trainers from the students perspective. The qualifications in this context is the main measure to get the metric for evaluation. On the other hand, when there is not a need to acquire a specific knowledge or expertise but when the learners wants to continue learning because he/she enjoys it, wants to keep learning and being active or any other personal motivation, then evaluation becomes a big challenge. This is the case of seniors’ education (citizens over 65 or retired). Which metrics should be used when evaluating institution? how we can know if those institutions are doing the work correctly ? how can the institution increase the quality and effectiveness ? From this need the project QEduSen (supported by the Lifelong Learning Programme of the European Commission) produced an evaluation toolkit
