As the field of technical and professional communication (TPC) has moved toward more inclusive perspectives, the use of decolonial frameworks has increased rapidly. However, TPC scholarship designed using decolonial frameworks lacks a clear, centralized definition and may overgeneralize and/or marginalize Indigenous concerns. Using a corpus analysis of TPC texts, we assess the ways that the field uses "decolonial" and propose a centralized definition of "decolonial" that focuses on rematriation of Indigenous land and knowledges. Further, we offer a heuristic that aids scholars in communication design appropriate for decolonial research and teaching strategies.

Risk communication is traditionally authored by institutions and addressed to the potentially affected publics for whom they are responsible. This study expands the scope of risk communication by analyzing safety guides produced by a hypermarginalized group for whom institutions show no responsibility: full-contact, street-level sex workers. Using corpus-assisted discourse analysis and keyword analysis to reveal patterns of word choices, the authors argue that the safety guides exhibit characteristics and qualities of professional communication: audience adaptation, social responsibility, and ethical awareness. This area of inquiry—the DIY, peer-to-peer, extrainstitutional risk communication produced by marginalized people—widens technical and professional communication's approach to risk communication.

Discursive infrastructures are forms of writing that remain mostly invisible but shape higher-level practices built upon their base. This article argues that citational practices are a form of discursive infrastructure that are bases that shape our work. Most importantly, we argue that the infrastructural base built through citation practices is in a moment of breakdown as increasing amounts of people call for more just citational practices that surface multiply marginalized and underrepresented (MMU) scholar voices. Consequently, this article both theorizes citations as infrastructure while also focusing on a case study of the MMU scholar database to help build a more equitable and socially just disciplinary infrastructure.
