La crisis desatada por la pandemia de la COVID-19 magnificó las asimetrías sociales. Caída del ingreso, mayor exposición al paro, inestabilidad laboral, incremento de las inequidades de género, colapso de la sanidad pública, y peores rendimientos en materia de aprendizaje e igualdad educativa se cuentan entre las consecuencias del aumento de la desigualdad global. En esta contribución argumento que la inequidad también se manifestó como desigualdad informativa. En un contexto donde la ponderación de la información se tornó más complicada, y (...) donde los aspectos epistémicos y axiológicos de la cultura del riesgo afloraron con singular claridad, la identidad social afectó la capacidad de evaluación de la información técnica y política. Los grupos sociales con menos educación e ingresos tuvieron una dieta informativa más restringida, con un énfasis en las redes sociales, menor conocimiento sobre el virus, ambivalencia frente a las medidas de actuación, o dificultades para ponderar la calidad de la información mediática e institucional. En definitiva, estuvieron más expuestos a las campañas de desinformación, particularmente agudizadas con el auge de las redes sociales en el mundo del capitalismo digital. A nivel individual, esta asimetría conspira contra la autonomía de las personas y su condición de ciudadanos. En el plano colectivo, amenaza el alcance y la calidad de la cultura científico-tecnológica y la gobernanza democrática. Es necesario discutir la relación entre desinformación y democracia, revalorizar el papel de la participación política para la gobernanza y la educación para la autonomía, el pensamiento y el desarrollo de una ética ciudadana cosmopolita.

Background Voluntary post-mortem donation to science (PDS) is the most appropriate source for body dissection in medical education and training, and highly useful for biomedical research. In Mexico, unclaimed bodies are no longer a legal source, but PDS is legally possible, although scarcely facilitated, and mostly ignored by the general population. Therefore, we aimed to evaluate the attitude and willingness for PDS and to identify a sociodemographic profile of people with willingness toward PDS. Methods A validated on-line survey was distributed (...) by the convenience method via the social networks of a Catholicism-inspired, private university in northern Mexico. Frequency analyses of all variables and coded free comments were complemented with association studies. Results Although the responder cohort (n = 143) was too small and biased to be representative of the university community (n = 13,500), willingness to post-mortem organ donation was 90.7% and to PDS 70.7%. In this cohort, PDS willingness had the strongest association with mature age (> 40 years old; P, 0.0008). Among young adults, willingness to PDS was the lowest among volunteers from technical and business schools and the highest among those from the social sciences (P, 0.009). Respondents from the social sciences were also the most consistent between attitude and behavior with respect to organ donation. A free comment option revealed respondents were interested in the unusual taboo topic. Conclusions A small, but sufficiently large proportion expressed willingness toward PDS. In our university cohort, which was biased in higher education and altruism, mature age and social interest were associated with PDS willingness. (shrink)

Elementary Buddhist logic and dialectical studies.

The Historical Dictionary of Philosophy, the _Historisches Wörterbuch der Philosophie,_ is distinguished by its particular presentation of philosophical terms, ideas and concepts. Rather than providing mere defintions or descriptive and analytical explanantions the _HWPh_ strictly applies the critical method of history of concepts developed by the eminent German scholar and philosopher Joachim Ritter. By means of precise and detailed references it documents the origin, first occurrence, the historical evolution and the changes of meaning of each concept, from Ancient Greek to (...) contemporary philosophy. For the reader this presentation is of unique value: it makes traceable the importance of terms and concepts at certain periods or for a particular philosopher, as well as its changes and development of meaning.

The crystallization behaviour of Fe 70.8 Nb 3.7 Cu 1 Al 2.7 Mn 0.7 Si 13.5 B 7.6 alloy prepared in the form of amorphous ribbons by melt-spinning technique was studied using differential scanning calorimetry and the temperature variation in resistivity. An X-ray diffaction and transmission electron microscopy study showed the formation of f -Fe and/or Fe 3 nanoparticles after the first stage of crystallization. The activation energy for this nanophase formation was 68 kcal mol m 1 . The brittleness (...) of the alloy increased with the formation of nanoparticles after heat treatment. Superior soft magnetic properties were achieved when the material was heat treated at 790 K for 15 min. The particle size at the optimum heat treatment condition for superior soft magnetic properties was found to be 6.0 - 0.5 nm which was less compared than for the Fe-Nb-Cu-Si-B system. The observed coercivity value at the optimum heat treatment condition was found to be 0.32 A m m 1 . The presence of Al in the alloy reduced the particle size and the magnetic anisotropy energy of the system, which resulted in superior soft magnetic properties of the heat-treated materials. (shrink)
