Patterns of sociolinguistic variation in teacher classroom speech

This study investigates sociolinguistic variation in teacher classroom speech. Based on a spoken‐French corpus produced by 59 teachers while teaching secondary school students (aged approximately 14–17 years) in four Ontario localities, it examines five cases of variant alternations. First, the study uses two comparative corpora to establish the social marking of the variants in the wider community. Second, it examines the teachers’ repertoire and frequency of use of variants in light of their social markedness. The study shows that the teachers use the standard variants at rates above even those found in the speech of the highest social strata within the wider community. Despite this normalizing impact of the classroom, the teachers also use all the non‐standard variants found in the wider community. Further, the study examines the impact on the teachers’ variant choice exerted by their socio‐professional characteristics and the communicative functions they perform in the classroom. It shows that the teachers’ use of variants is influenced by their gender, the subject taught, and the communicative functions performed in the classroom in ways that are in line with the social markedness of the variants in the wider community.     

The mouths of others: The linguistic performance of race in Bermuda

This paper examines the behaviour of one linguistic feature among one black and one white group of Bermudian men over the age of 50. The acoustic analysis of the mouth vowel, one of the most heavily stereotyped sounds of Bermudian English, is used as a window onto linguistic parody observed in the white group, a community of practice known locally for theatrical dialect performance. In combination with contextual analysis, and in light of social conditions in Bermuda, phonetic findings suggest that this linguistic practice is not only a performance of “Bermudian‐ness,” but also a performance of a racialized stereotype which reflects and reinforces the raciolinguistic hierarchies of contemporary Bermudian society. The paper introduces this under‐researched and unusual sociolinguistic setting to the literature on racialized mock language, as well as attesting further to the usefulness of methods that examine highly self‐conscious speech.     

Racialisation and the afterlife of colonial divide and rule: a response to Avtar Brah

In this response to Avtar Brah’s review of Race Otherwise (2017) I briefly clarify the relationship between the concepts ‘racism’, ‘race’ and ‘racialisation’. I expand my framing of the book as less about racism and more about specific processes of racialisation. To this end I draw on material from and beyond the book to illustrate the value of the concept ‘racialisation’ for understanding the afterlife of colonial divide and rule in South Africa and other former British colonies in Africa. I show the ways in which re-articulations of the ‘signification-action complex’ at the heart of processes of racialisation in post-1994 South Africa produce a politics of evasion as well as tensions between struggles for recognition on the one hand and on the other, struggles for justice and freedom. With these re-articulations come varying convergences - of claims of culture, belonging and victimhood, genomic science, jurisprudence and global discourse on indigenous rights – that reify notions of ‘race’ and ‘tribe’.     

Civic discourse on Facebook during the Australian same‐sex marriage postal plebiscite

In 2017 the Australian Government undertook a national survey to determine public support for the legalisation of same‐sex marriage. This raised concerns the ‘plebiscitary' act may create harms to two groups: LGBTI people and those religious people with strong attachment to heteronormative marriage. Justifying the process, the Government advanced the possibility of civil dialogue generative of understanding. While instances of hate speech in public spaces were reported, this paper examines comparatively private speech during the period. Based on an analysis of posts to relevant Facebook pages, this analysis found opponents to same‐sex marriage were more highly mobilised online, and considerable differences in the character of online debate for and against the proposed changes. Importantly, while uncivil and ‘hate' speech were part of online conversations, the overall quantum of this uncivil discourse was lower than many feared. Additionally, the process did not generate considerable democratic dialogue around policy alternatives and rationales, particularly among ‘Yes' campaign supporters who were more homogenous in their acceptance of dominant campaign framing of the issue than their opponents. Significantly for ongoing public debates about public values like educational access and freedom of expression, opponents to change focused their arguments against same‐sex marriage around a subset of unrelated issues: free speech, religious freedoms, and diversity in public schools.
