Deaf-Latinx K–12 students are the largest group of racially minoritized students in the US, lagging far behind the complimentary proportion of Deaf-whites in obtaining degrees. Educational institutions have sustained and reproduced privilege and inequality patterns. This article explores how using Deaf-Latinx Critical Theory (Deaf-LatCrit) in educational research facilitates Deaf-Latinx epistemology, intersectionality, and cultural intuition in autoethnography. It effectively captured how I, a first-generation DeafChicana college student, navigated structural inequity in educational institutions. When extant literature and resources are limited, counter-stories must be included to expand knowledge about issues of educational equity, and promote accountability, decision-making, and action. Autoethnography validates my DeafChicana existence and calls for attention to multiple interlocking issues within the educational system. Deaf-LatCrit and autoethnography provided the platform for me to conduct this study, which derives primarily from my own higher educational experiences. This Deaf-Latinx ethnographic study provided me a valuable tool and a safe outlet to reflect on my academic experiences, and exposed five thematic concerns: raciolinguicism, interpreter quality, classroom exclusion, institutional and structural systems, and professional development. Recommendations are included to help individuals become more aware of unconscious and conscious discriminations so we can together improve support for DeafBlind, DeafDisabled, Deaf, and Hard of Hearing-Latinx students in higher education.

Haplogroup R1b-M269 comprises most Western European Y chromosomes; of its main branches, R1b-DF27 is by far the least known, and it appears to be highly prevalent only in Iberia. We have genotyped 1072 R1b-DF27 chromosomes for six additional SNPs and 17 Y-STRs in population samples from Spain, Portugal and France in order to further characterize this lineage and, in particular, to ascertain the time and place where it originated, as well as its subsequent dynamics. We found that R1b-DF27 is present in frequencies ~40% in Iberian populations and up to 70% in Basques, but it drops quickly to 6-20% in France. Overall, the age of R1b-DF27 is estimated at ~4,200 years ago, at the transition between the Neolithic and the Bronze Age, when the Y chromosome landscape of W Europe was thoroughly remodeled. In spite of its high frequency in Basques, Y-STR internal diversity of R1b-DF27 is lower there, and results in more recent age estimates; NE Iberia is the most likely place of origin of DF27. Subhaplogroup frequencies within R1b-DF27 are geographically structured, and show domains that are reminiscent of the pre-Roman Celtic/Iberian division, or of the medieval Christian kingdoms. ; Funding was provided by the Agencia Estatal de Investigación and Fondo Europeo de Desarollo Regional (FEDER) (grants CGL2013-44351-P, CGL2016-75389-P), by Agència de Gestió d'Ajuts Universitaris i de la Recerca (Generalitat de Catalunya) grant 2014 SGR 866, and by the Basque Government (IT-424-07).
