In most languages, most of the syntactic dependency relations found in any given sentence are projective: the word-word dependencies in the sentence do not cross each other. Some syntactic dependency relations, however, are non-projective: some of their word-word dependencies cross each other. Non-projective dependencies are both rarer and more…

Expressing causal relations plays a central role in academic writing. While it is important that writing instructors assess and provide feedback on learners' causal discourse, it could be a very time-consuming task. In this respect, automated writing evaluation (AWE) tools may be helpful. However, to date, there have been no AWE tools capable of…

The purpose of the present study is to investigate the impact of learners' L1s and proficiency levels on their written production. This study also examined the influence of speech upon their writing. The following research questions were explored: (a) How do L1 and proficiency levels of learners affect their degrees of register awareness? (b)…

This corpus-based study demonstrates a case of bidirectional cross-linguistic influence in the acquisition of right-dislocation by Cantonese-English bilingual children and interprets the results in relation to Hulk and Müller's hypothesis for cross-linguistic influence. Longitudinal data reveal qualitative and quantitative differences between…

Study abroad is an under-researched domain of language learning. Moreover, most investigations of this phenomenon adopt traditional structuralist approaches, wherein outcomes of study abroad are assessed solely in terms of proficiency gains as measured through conventional exams. The present study builds upon an emerging body of poststructuralist…

Sarcasm production and comprehension have been traditionally described in terms of pragmatic factors. Lexical cues have received less attention, but they may be important potential indicators. A major obstacle to examining such features is determining sarcastic intent. One solution is to analyze statements explicitly marked as being sarcastic.…

There have been many studies on the acquisition of English unaccusative verbs which make use of learner corpora. Most of these studies have so far concluded that even advanced learners of English ungrammatically passivize unaccusative verbs and produce sentences such as "*The accident was happened" and "*The mobile phone was…

This paper investigates how boosters are used by qualitative and quantitative research article writers to express certainty. Boosters are words such as "definitely," "sure," "demonstrate" which signal writers' assurance in what they say. Drawing on a corpus of 200 research articles in Applied Linguistics, this study…

Most educators are aware that some students utilize web-based machine translators for foreign language assignments, however, little research has been done to determine how and why students utilize these programs, or what the implications are for language learning and teaching. In this mixed-methods study we utilized surveys, a translation task,…

A large body of research in the learning sciences has focused on students' commonsense science knowledge--the everyday knowledge of the natural world that is gained outside of formal instruction. Although researchers studying commonsense science have employed a variety of methods, 1-on-1 clinical interviews have played a unique role. The data…

To investigate potential causes of L2 performance deficits that correlate with age of onset, we use a computational model to explore the individual contributions of L1 entrenchment and aspects of memory development. Since development and L1 entrenchment almost invariably coincide, studying them independently is seldom possible in humans. To avoid…

This dissertation investigates how the Taiwanese Tone Sandhi Groups are perceived, and the acoustic/phonetics correlates of listeners' judgments. A series of perception experiments have been conducted to scrutinize the following topics--Taiwanese tone neutralization, Tone Sandhi Group (TSG) as a prosodic domain, perceived boundary strength in…

This study examines the frequency effect of two-word collocations involving "para" "to," "for" (e.g. "fui para," "para que") on the reduction of "para" to "pa" (in Spanish) and "pra" (in Portuguese). Collocation frequency effects demonstrate that language speakers…

In this study we explored variation in the countability of nouns in Outer Circle, Expanding Circle and lingua franca Englishes, a phenomenon which is frequently cited as a marker of Inner Circle norms in TESOL and of endonormative and emerging varieties in the Outer and Expanding Circles. We inspected a set of mass nouns like "information" and…

This dissertation proposes a structured semantic account of the polysemous Russian verbal prefix "po-" within the theoretical framework of cognitive linguistics and using corpus linguistic methods. While scholarly consensus identifies five meanings for "po-" and an additional meaning in conjunction with the suffix--"yva"--, the relationships among…
