Las intervenciones ortográficas de Sebastián Díaz
En el marco de un dilogo crtico entre la historia cultural y la perspectiva glotopoltica, se examinan las modificaciones ortogrficas propuestas por Sebastin Daz (1741-1813) como intervenciones normativas. El abordaje discursivo del prlogo a su enciclopedia, a travs del constructo terico-analtico de ideologas lingsticas, revela que las reformas ortogrficas de Daz son prcticas prescriptivas que, en acuerdo y en tensin con el discurso acadmico, pret…
Male-Dominated Occupations and Substance Use Disorders in Young Adulthood
This article examined associations between male-dominated occupations and substance use disorders in young adulthood, accounting for adolescent experiences of work intensity (more than 15 hr a week at 16 to 17 years of age) and substance use (i.e., smoking, heavy drinking, cannabis, and illicit drug use). The moderating effects of biological sex and coming from a family with a low socioeconomic status (SES) were also assessed. Data were from a 10…
Vitamin D deficiency is common and is associated with overweight in Mexican children aged 1–11 years
Objective To assess vitamin D dietary sources, intake and 25-hydroxyvitamin D status and their association with individual and sociodemographic characteristics in Mexican children. Design Data obtained from 2695 children aged 1–11 years from the Mexican National Health and Nutrition Survey (2012) were analysed. Diet was assessed by a 141-item FFQ. 25-Hydroxyvitamin D was measured by a chemiluminescent assay. Results Mean vitamin D intake was 3·38…
Genetic Diversity and Differentiation in Urban and Indigenous Populations of Mexico
Aside from the admixture between indigenous people and people from overseas, populations in Mexico changed drastically after the Spanish conquest of the sixteenth century, forming an intricate history that has been underutilized in understanding the genetic population structure of Mexicans. To infer historical processes of isolation, dispersal, and assimilation, we examined the phylogeography of mitochondrial (mt) DNA and Y-chromosome lineages in…
