Sensitivity of dispersion measures to distributional patterns and corpus design
Recent work has shown that dispersion measures respond to multiple features in the data: Juilland’s D varies systematically with the number of corpus parts, and all commonly used indices are affected by the frequency of an item. This study uses a simulation approach to provide further insights into the sensitivity of dispersion measures to differences in corpus design (number of texts, average text length, distribution of text lengths) and distri…
Evaluating risk factors and protective clinical interventions for opioid use disorder and overdose in American Indian/Alaska Native populations
American Indian/Alaska Native (AI/AN) populations often experience higher rates of opioid use disorder (OUD) and opioid overdose deaths compared to other racial/ethnic groups. This study evaluates modifiable risk factors and protective clinical interventions for OUD and overdose prevention interventions among AI/AN patients to understand potential points of intervention. This retrospective cohort study utilized electronic health record data from …
Achieving stability in corpus-based analysis of word types
Rank-ordered lists of word types are ubiquitous in corpus linguistics and applied linguistics. Word lists are commonly developed as aids for language teaching and learning, vocabulary testing, and language description. Yet, these lists are often produced and used without evaluation of their stability — or replicability — across corpus samples. Our primary objective in this paper is to describe the cumulative state of knowledge regarding the stabi…

Writing Trajectories of Grammatical Complexity at the University
Grammatical complexity has been established as a key indicator of language and writing development (Ortega 2003; Bulté and Housen, 2014; Crossley and McNamara 2014). The present study uses the Register-Functional approach to complexity (Biber et al. 2022) to compare the development of L1 English and L2 English writers across year of study and discipline in the British Academic Written English corpus. It also introduces a novel method of examining…
Which Words Matter Most? Operationalizing Lexical Prevalence For Rank-Ordered Word Lists
The words in a language or language variety are often rank ordered in lists that are meant to reflect the relative importance of those words to language users and learners of a language. This rank ordering is done on the basis of the relative prevalence of words in a corpus. Lexical prevalence is often operationalized as measures of frequency, dispersion, or adjusted frequency. Yet, to date, there is no consensus on best practices for identifying…

Swearing, discourse and function in conversational British English
In this paper we look at the role that macrostructures in discourse have to play in the study of swearing. While studied in isolation, such macrostructures have not yet been studied comprehensively and the range of macrostructures studied has been small. By contrast, work on microstructures is much better developed. In response to this, using spoken corpus data from the BNC2014, we take two approaches to studying discourse in this paper. In the f…
Sexuality and Gender Identity Inequities in Substance Use Disorder and Its Treatment among American Indian, Alaska Native, and Native Hawaiian College Students
BACKGROUND: The aim of this study was to investigate inequities in substance use disorder (SUD) diagnosis, opioid misuse, marijuana misuse, SUD treatment utilization, and utilization of university mental health services among sexual and gender minority (SGM) American Indian, Alaska Native, and Native Hawaiian (AI/AN/NH) college students. METHODS: Data consisting of 8,103 AI/AN/NH students' responses to the American College Health Association's Na…

Identifying and describing functional discourse units in the BNC Spoken 2014
On the surface, it appears that conversational language is produced in a stream of spoken utterances. In reality conversation is composed of contiguous units that are characterized by coherent communicative purposes. A large number of important research questions about the nature of conversational discourse could be addressed if researchers could investigate linguistic variation across functional discourse units. To date, however, no corpus of co…

Lexical dispersion and corpus design
Lexical dispersion is typically measured across arbitrary corpus parts of equal size. In this study, we apply D A – a new dispersion index designed for unequal-sized corpus parts – to the British National Corpus (BNC) in a series of cases studies to show that the dispersion of a word is strongly influenced by the corpus units or parts it is measured across. Our results show that dispersion should be measured and interpreted based on corpus units …
Research in progress
Founded in 1990, the Applied Linguistics program at Northern Arizona University (NAU) represents a staple of scholarly activity and graduate training in the field. Indeed, the program, which consists of ten core faculty members and approximately 30 Ph.D. students has been and remains highly active and vibrant in terms of professional/societal involvement and, of course, research. This article highlights recent and current projects carried out by …
Linguistic Perspectives on Register
Language users change their written and spoken language according to the situational characteristics and communicative purpose of production—that is, according to the register being produced. Research on registers has focused on register description or patterns of register variation, on detailed analysis of individual linguistic features or an account for the use of a broad range of linguistic features, and on the distinction between written and …
More Than Frequency? Exploring Predictors of Word Difficulty for Second Language Learners
Frequency is often the only variable considered when researchers or teachers develop vocabulary materials for second language (L2) learners. However, researchers have also found that many other variables affect vocabulary acquisition. In this study, we explored the relationship between L2 vocabulary acquisition and a variety of lexical characteristics using vocabulary recognition test data from L2 English learners. Conducting best subsets multipl…
Corpus linguistics and language testing
The use of corpora and corpus linguistic methods in language testing research is increasing at an accelerated pace. The growing body of language testing research that uses corpus linguistic data is a testament to their utility in test development and validation. Although there are many reasons to be optimistic about the future of using corpus data in language testing, the convergence of these two fields introduces uncharted waters that should be …
Academic Writing Development at the University Level
Using the British Academic Written English corpus, this study focuses on the use of grammatical complexity features in university level texts written by first language (L1) English writers to demonstrate knowledge and perform other specialized tasks required of advanced academic writers. While the primary focus of the analysis is on writing development from first-year undergraduate to graduate students, we also consider interactions with discipli…
Toward more accountability
Whereas the alternation between the s -genitive ( the New Year's message ) and the of -genitive ( the message of the New Year ) is well documented, our study offers a more accountable analysis of genitive variation by including noun-noun (NN)-genitives ( the New Year message ). We consider four different variable contexts ( s versus of , NN versus of , NN versus s , and NN versus s versus of ), which we analyze using regression analysis. The data…
Publication type and discipline variation in published academic writing
This study uses Multi-Dimensional analysis to describe linguistic variation in a corpus of published academic writing across three publication types in two disciplines. The resulting five dimensions were labeled: “Affective synthesis versus specialized information density”, “Definition and evaluation of new concepts”, “Author-centered stance”, “Reader-friendly narrative”, and “Abstract observation and description”. Factorial ANOVAs were used to t…
Bootstrapping in Applied Linguistics
Parametric analyses such as t tests and ANOVAs are the norm—if not the default—statistical tests found in quantitative applied linguistics research (Gass 2009). Applied statisticians and one applied linguist (Larson-Hall 2010, 2012; Larson-Hall and Herrington 2010), however, have argued that this approach may not be appropriate for small samples and/or nonnormally distributed data (e.g. Wilcox 2003), both common in second language (L2) research. …
