title: Use of three isotopes to calibrate human bone radiocarbon determinations from Kainapirina (SAC), Watom Island, Papua New Guinea

authors: Petchey, Fiona

subjects: archaeological dating

abstract: In archaeological dating, the greatest confidence is usually placed upon radiocarbon results of material that can be directly related to a defined archaeological event. Human bone should fulfill this requirement, but bone dates obtained from Pacific sites are often perceived as problematic due to the incorporation of ¹⁴C from a range of different reservoirs into the collagen via diet. In this paper, we present new human bone gelatin results for 2 burials from the SAC archaeological site on Watom Island, Papua New Guinea, and investigate the success of calibrating these determinations using dietary corrections obtained from δ³⁴S, δ¹⁵N, and δ¹³C isotopes.

title: Improving mental wellbeing among university students via a smartphone application based on Acceptance and Commitment Therapy

authors: Li, Fengshan

abstract: The number of university students experiencing mental disturbances is increasing. Due to the impact it has on students’ academic life, there is a need for an efficient, convenient, and cost- effective intervention which can be widely applied to university populations. Acceptance and
Commitment Therapy (ACT) is an effective behavioural treatment for a range of psychological disorders. ACT has a transdiagnostic feature, as it focus on educating individuals to be aware of their internal experiences, such as thoughts and feelings and to accept them, instead of suppressing or avoiding them. The fundamental goal of ACT is to promote individuals’ psychological flexibility when faced with challenging events by addressing their valued life goals. ACT CompanionTM app is an ACT-based smartphone app which incorporates exercises to assist users achieve their treatment goals. I used a single- subject design to examine the efficacy of the ACT CompanionTM app in reducing measures of stress, anxiety, depression, and psychological flexibility for 9 university participants. Graphs showed that app use lowered daily stress levels for all participants. At a group level, there was a significant decrease in anxiety, stress, depressive symptoms, and negative emotions. However, no significant effect of app use on mindfulness and psychological flexibility. Overall, the results suggest that the ACT CompanionTM app is a promising approach for improving mental wellbeing among university students.

title: No explanation required: Entrenchment and perception of Māori loanwords in a diachronic newspaper corpus of New Zealand English

authors: Levendis, Katharine Joy

subjects: New Zealand English

abstract: Māori loanwords are uncontestably the most notable feature of New Zealand English (Gordon, 2005; Macalister, 2006b). Although frequencies of Māori loanwords are reported to be increasing in recent years (Macalister, 2006b), and analyses strongly indicate a skew in loanwords across certain topics (Davies & Maclagan, 2006; de Bres, 2006), no studies have yet addressed whether Māori loanword behaviour differs in a corpus restricted to a single topic (with the exception of Calude, Miller, Harper, & Whaanga, Forthcoming). Nor has a thorough diachronic analysis been made on the subject since Davies and Maclagan (2006) and Macalister (2006b). This thesis is concerned with frequency of use and perception of Māori loanwords in a diachronic corpus restricted to a singular theme: te Wiki o te Reo Māori, Māori Language Week. Using a quantitative methodology in a corpus constructed from New Zealand regional and national newspaper articles spanning 2008-2017, average Māori loanword frequencies are found to be almost 5 times that of the most recent comparable diachronic study (Macalister, 2006b), and demonstrate a statistically significant diachronic increase in use. In contrast, the markedness (or translation) of Māori loanwords shows a statistically significant decreasing diachronic trend over the 10-year period. However, practice of marking appears to be affected by user perceptions and intention to educate, and therefore cannot be relied upon as a gauge of loanword entrenchment. Other conventional measures of loanword entrenchment such as frequency, listedness and morphological assimilation are also shown to be unreliable when considered independently from one another, and in cases such as that of New Zealand English where a change from above influenced by social and cultural factors (Māori loanwords functioning as an expression of political attitude and stance) appears to be interfering in loanword use. Measurement of Māori loanword entrenchment cannot be made using the same criteria as loanwords from non-threatened languages, and suggestions are made for the revised criteria for studying loanword entrenchment which takes into account the sociolinguistic context in which the loanwords are used.
