Changes in the pronunciation of Māori and implications for teachers and learners of Māori

This paper discusses changes in the pronunciation of Māori and implications for teachers and learners of Māori. Data on changes in the pronunciation of Māori derives from the MAONZE project (Māori and New Zealand English with support from the Marsden fund). The project uses recordings from three sets of speakers to track changes in the pronunciation of Māori and evaluate influence from English. Results from the project show changes in both vowel quality and vowel duration and some evidence of diphthong mergers in pairs such as ai/ae and ou/au, especially amongst the younger speakers. In terms of duration the younger speakers are producing smaller length distinctions between long/short vowel pairs other than /ā, a/. We discuss the implications of such changes for those teaching Māori and for students learning Māori as a subject. These changes raise interesting questions concerning the pronunciation of Māori by future generations

/u/ fronting and /t/ aspiration in Māori and New Zealand English

This article examines the relationship between the frontness of /u/ and the aspiration of /t/ in both Māori and New Zealand English (NZE). In both languages, these processes can be observed since the earliest recordings dating from the latter part of the nineteenth century. We report analyses of these developments for three groups of male speakers of Māori spanning the twentieth century. We compare the Māori analyses with analyses of related features of the speakers' English and of the English of monolingual contemporaries. The occurrence of these processes in Māori cannot be seen simply as interference from NZE as the Māori-speaking population became increasingly bilingual. We conclude that it was the arrival of English with its contrast between aspirated and unaspirated plosives, rather than direct borrowing, that was the trigger for the fronting of the hitherto stable back Māori /u/ vowel together with increased aspiration of /t/ before both /i/ and /u/

Seen in Science: LGBTQ+ Inclusivity in Anatomy & Physiology Texts

Biology is unique from other science disciplines in that concepts taught in core classes can inform our student’s understanding of sex and gender. A biology major encounters lessons on sex determination, sexual reproduction, and sex characteristics in their courses. The language used in these units matters. It is imperative that educators consider how the language, examples, and content that we use in classrooms drive (or not) inclusivity for gender- and sexuality-diverse (GSD) (aka LGBTQ+) individuals. We chose to analyze four college-level human anatomy/physiology (AP) textbooks for GSD population inclusivity. We adopted a queer theory framework to critically examine how sex, gender, and sexuality are presented in textbooks used by emerging healthcare professionals at the undergraduate level. We conducted a close read of the selected textbooks using similar evaluation criteria to existing textbook analyses grounded in queer theory (Bazzul & Sykes, 2011; Campo-Engelstein & Johnson, 2014). All textbooks we examined showed examples of each of the categories that we originally identified as hindering inclusivity of gender-diverse populations. Out of the four textbooks in our study, Seeley’s Anatomy & Physiology was the most inclusive, had fewer instances in which sex/gender binaries, norms, or domains were perpetuated, and contained the only instances of intersex inclusivity in image and text, but even this book framed material as androcentric and heteronormative. We believe it is necessary to share our findings; hopefully publishers will be more mindful of these discursive acts and be receptive to changing their books to be more inclusive in future editions.https://ir.library.louisville.edu/uars/1025/thumbnail.jp

Brown Dwarf Jets: Investigating the Universality of Jet Launching Mechanisms at the Lowest Masses

Recently it has become apparent that proto-stellar-like outflow activity extends to the brown dwarf (BD) mass regime. While the presence of accretion appears to be the common ingredient in all objects known to drive jets fundamental questions remain unanswered. The more prominent being the exact mechanism by which jets are launched, and whether this mechanism remains universal among such a diversity of sources and scales. To address these questions we have been investigating outflow activity in a sample of protostellar objects that differ considerably in mass and mass accretion rate. Central to this is our study of brown dwarf jets. To date Classical T Tauri stars (CTTS) have offered us the best touchstone for decoding the launching mechanism. Here we shall summarise what is understood so far of BD jets and the important constraints observations can place on models. We will focus on the comparison between jets driven by objects with central mass < 0.1M \odot and those driven by CTTSs. In particular we wish to understand how the the ratio of the mass outflow to accretion rate compares to what has been measured for CTTSs.Comment: Proceedings of IAU meeting 275, "Jets at All Scales

Acoustic Analysis of Maori: Historical Data

We present initial results of an acoustic analysis of the vowel system of a native speaker of Maori, RTH, who was born in 1885. RTH was recorded in 1947 by the Mobile Disc Recording Unit of the New Zealand Broadcasting Service and the tape forms part of the Mobile Unit (MU) Archive at the University of Canterbury. RTH speaks in Maori and translates his material into English, though the English contains sections of whakapapa (genealogy) which are almost pure Maori. In this paper, we compare analyses of his vowel system when he is speaking in Maori and in English and also when he is using Maori words during his translations into English. RTH would have learnt his Maori at a time when influence from English was minimal. This analysis is therefore the first step in providing a reference acoustic analysis for the Maori language and for establishing the long-term influence of English on the pronunciation of Maori and vice versa. The analysis of RTH will be combined with an analysis of the other Maori speakers included in the MU archive together with other first language Maori speakers born in the late nineteenth century

Early changes in emotional processing as a marker of clinical response to SSRI treatment in depression

Antidepressant treatment reduces behavioural and neural markers of negative emotional bias early in treatment and has been proposed as a mechanism of antidepressant drug action. Here, we provide a critical test of this hypothesis by assessing whether neural markers of early emotional processing changes predict later clinical response in depression. Thirty-five unmedicated patients with major depression took the serotonin re-uptake inhibitor (SSRI), escitalopram (10 mg), over 6 weeks, and were classified as responders (22 patients) versus non-responders (13 patients), based on at least a 50% reduction in symptoms by the end of treatment. The neural response to fearful and happy emotional facial expressions was assessed before and after 7 days of treatment using functional magnetic resonance imaging. Changes in the neural response to these facial cues after 7 days of escitalopram were compared in patients as a function of later clinical response. A sample of healthy controls was also assessed. At baseline, depressed patients showed greater activation to fear versus happy faces than controls in the insula and dorsal anterior cingulate. Depressed patients who went on to respond to the SSRI had a greater reduction in neural activity to fearful versus happy facial expressions after just 7 days of escitalopram across a network of regions including the anterior cingulate, insula, amygdala and thalamus. Mediation analysis confirmed that the direct effect of neural change on symptom response was not mediated by initial changes in depressive symptoms. These results support the hypothesis that early changes in emotional processing with antidepressant treatment are the basis of later clinical improvement. As such, early correction of negative bias may be a key mechanism of antidepressant drug action and a potentially useful predictor of therapeutic response

Predicting treatment response in depression: the role of anterior cingulate cortex.

Background: Identification of biomarkers predicting therapeutic outcome of antidepressant treatment is one of the most important tasks in current research because it may transform the lengthy process of finding the right treatment for a given individual with depression. In the current study, we explored the potential of pretreatment pregenual anterior cingulate cortex activity as a putative biomarker of treatment response. // Methods: Thirty-two medication-free patients with depression were treated for 6 weeks with a selective serotonin reuptake inhibitor, escitalopram. Before treatment began, patients underwent an fMRI scan testing response to brief, masked, presentations of facial expression depicting sadness and happiness. // Results: After 6 weeks of treatment, there were 20 selective serotonin reuptake inhibitor responders and 12 nonresponders. Increased pretreatment pregenual anterior cingulate cortex activity to sad vs happy faces was observed in responders relative to nonresponders. A leave-one-out analysis suggested that activity in the anterior cingulate cortex was able to predict response status at the level of the individual participant. // Conclusions: The study supports the notion of pregenual anterior cingulate cortex as a promising predictor of antidepressant response
