"Service-learning" (SL) is an experiential pedagogy that engages students in working for, with, and in communities in need. While prior research has explored the effects of SL on second language (L2) users' (perceived) language development (e.g., Gaugler & Matheus, 2019), intercultural awareness (e.g., Sa´nchez-Naranjo, 2021), and…

This observation leads some to propose that the dialogue lacks conceptual coherence. I argue that the interlocutors tangentially attend to previously stated points-of-view and attempt to…

Studies in English as a Foreign Language (EFL) indicate that the use of discourse markers (DMs) in the academic writing of second language learners improves the overall quality of these texts by contributing to their cohesion and comprehensibility (Saif Modhish 2012; Jalilifar 2008; Intaraprawat & Steffensen 1995). However, despite the…

The dissertation paints a cultural-historical portrait of the New Criticism, a formalist school of twentieth-century literary criticism. My case study revisits the trajectory of this vital school of thought through a fine-grained textual comparison of critical essays produced by principal affiliates. Using "genre" as a guiding concept, I…

As the boom in the older adult population continues to grow, so too grows the number of persons suffering from cognitive diseases, such as dementia of the Alzheimer's type (DAT). Older Latinos diagnosed with the disease make up 4 percent (200,000) of the current population; however, little research on bilinguals with DAT has been carried out…
