/u/ fronting and /t/ aspiration in MÄori and New Zealand English
This article examines the relationship between the frontness of /u/ and the aspiration of /t/ in both MÄori 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 MÄori spanning the twentieth century. We compare the MÄori analyses with analyses of related features of the speakers' English and of the English of monolingual contemporaries. The occurrence of these processes in MÄori cannot be seen simply as interference from NZE as the MÄori-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 MÄori /u/ vowel together with increased aspiration of /t/ before both /i/ and /u/
Changes in the pronunciation of MÄori and implications for teachers and learners of MÄori
This paper discusses changes in the pronunciation of MÄori and implications for teachers and learners of MÄori. Data on changes in the pronunciation of MÄori derives from the MAONZE project (MÄori 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 MÄori 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 /Ä, a/. We discuss the implications of such changes for those teaching MÄori and for students learning MÄori as a subject. These changes raise interesting questions concerning the pronunciation of MÄori by future generations
Pruning Algorithms for Pretropisms of Newton Polytopes
Pretropisms are candidates for the leading exponents of Puiseux series that
represent solutions of polynomial systems. To find pretropisms, we propose an
exact gift wrapping algorithm to prune the tree of edges of a tuple of Newton
polytopes. We prefer exact arithmetic not only because of the exact input and
the degrees of the output, but because of the often unpredictable growth of the
coordinates in the face normals, even for polytopes in generic position. We
provide experimental results with our preliminary implementation in Sage that
compare favorably with the pruning method that relies only on cone
intersections.Comment: exact, gift wrapping, Newton polytope, pretropism, tree pruning,

Determinants of impact : towards a better understanding of encounters with the arts
The article argues that current methods for assessing the impact of the arts are largely based on a fragmented and incomplete understanding of the cognitive, psychological and socio-cultural dynamics that govern the aesthetic experience. It postulates that a better grasp of the interaction between the individual and the work of art is the necessary foundation for a genuine understanding of how the arts can affect people. Through a critique of philosophical and empirical attempts to capture the main features of the aesthetic encounter, the article draws attention to the gaps in our current understanding of the responses to art. It proposes a classification and exploration of the factorsâsocial, cultural and psychologicalâthat contribute to shaping the aesthetic experience, thus determining the possibility of impact. The âdeterminants of impactâ identified are distinguished into three groups: those that are inherent to the individual who interacts with the artwork; those that are inherent to the artwork; and âenvironmental factorsâ, which are extrinsic to both the individual and the artwork. The article concludes that any meaningful attempt to assess the impact of the arts would need to take these âdeterminants of impactâ into account, in order to capture the multidimensional and subjective nature of the aesthetic experience
Exenatide once weekly versus placebo in Parkinson's disease: a randomised, double-blind, placebo-controlled trial
BACKGROUND: Exenatide, a glucagon-like peptide-1 (GLP-1) receptor agonist, has neuroprotective effects in preclinical models of Parkinson's disease. We investigated whether these effects would be apparent in a clinical trial. METHODS: In this single-centre, randomised, double-blind, placebo-controlled trial, patients with moderate Parkinson's disease were randomly assigned (1:1) to receive subcutaneous injections of exenatide 2 mg or placebo once weekly for 48 weeks in addition to their regular medication, followed by a 12-week washout period. Eligible patients were aged 25-75 years, had idiopathic Parkinson's disease as measured by Queen Square Brain Bank criteria, were on dopaminergic treatment with wearing-off effects, and were at Hoehn and Yahr stage 2·5 or less when on treatment. Randomisation was by web-based randomisation with a two strata block design according to disease severity. Patients and investigators were masked to treatment allocation. The primary outcome was the adjusted difference in the Movement Disorders Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) motor subscale (part 3) in the practically defined off-medication state at 60 weeks. All efficacy analyses were based on a modified intention-to-treat principle, which included all patients who completed any post-randomisation follow-up assessments. The study is registered at ClinicalTrials.gov (NCT01971242) and is completed. FINDINGS: Between June 18, 2014, and March 13, 2015, 62 patients were enrolled and randomly assigned, 32 to exenatide and 30 to placebo. Our primary analysis included 31 patients in the exenatide group and 29 patients in the placebo group. At 60 weeks, off-medication scores on part 3 of the MDS-UPDRS had improved by 1·0 points (95% CI -2·6 to 0·7) in the exenatide group and worsened by 2·1 points (-0·6 to 4·8) in the placebo group, an adjusted mean difference of -3·5 points (-6·7 to -0·3; p=0·0318). Injection site reactions and gastrointestinal symptoms were common adverse events in both groups. Six serious adverse events occurred in the exenatide group and two in the placebo group, although none in either group were judged to be related to the study interventions. INTERPRETATION: Exenatide had positive effects on practically defined off-medication motor scores in Parkinson's disease, which were sustained beyond the period of exposure. Whether exenatide affects the underlying disease pathophysiology or simply induces long-lasting symptomatic effects is uncertain. Exenatide represents a major new avenue for investigation in Parkinson's disease, and effects on everyday symptoms should be examined in longer-term trials.

Business ethics as practice
In this article we develop a conceptualization of business ethics as practice. Starting from the view that the ethics that organizations display in practice will have been forged through an ongoing process of debate and contestation over moral choices, we examine ethics in relation to the ambiguous, unpredictable, and subjective contexts of managerial action. Furthermore, we examine how discursively constituted practice relates to managerial subjectivity and the possibilities of managers being moral agents. The article concludes by discussing how the 'ethics as practice' approach that we expound provides theoretical resources for studying the different ways that ethics manifest themselves in organizations as well as providing a practical application of ethics in organizations that goes beyond moralistic and legalistic approaches. © 2006 British Academy of Management
