title: Urban food planning and management in Melbourne: current challenges and practical insights

authors: Vieira, Leticia Canal

abstract: Over the last decades, local governments have begun to develop urban food planning instruments focused on improving public health and environmental sustainability, but shortcomings still exist. This paper builds on the case of the Melbourne Metropolitan Region (Australia) to elaborate on how urban food planning and management can address the challenges exposed by a systemic approach. Challenges include strengthening local food economies, developing a nexus between the urban environment, public health, and sustainability, and the circular management of food production resources. Our study contributes to urban food planning and management practice by identifying how policy instruments have successfully addressed these key challenges, and existing inconsistencies between policies and planning. Furthermore, policies should go beyond incentives for urban gardens and explore new areas of intervention, including integrating local producers and retailers into urban food planning, prioritizing fresh food commercialization over ultra-processed products, and integrating composting into waste management.

title: Good lattice rules based on the general weighted star discrepancy

authors: Sinescu, Vasile

subjects: mathematics

abstract: We study the problem of constructing rank-  lattice rules which have good bounds on the ``weighted star discrepancy''. Here the non-negative weights are general weights rather than the product weights considered in most earlier works. In order to show the existence of such good lattice rules, we use an averaging argument, and a similar argument is used later to prove that these lattice rules may be obtained using a component-by-component (CBC) construction of the generating vector. Under appropriate conditions on the weights, these lattice rules satisfy strong tractability bounds on the weighted star discrepancy. Particular classes of weights known as ``order-dependent'' and ``finite-order'' weights are then considered and we show that the cost of the construction can be very much reduced for these two classes of weights.

title: Lost in translation or lack of nuance? Perception of (near-)synonymy of common te reo Māori loanwords in New Zealand English

authors: Pohl, Alexander

abstract: Ongoing contact between languages and their speakers inevitably leads to a flow of words being borrowed from one language into another. Research in the field of language contact has established and documented the kinds of borrowed words that stick in their recipient language (Haspelmath 2009; Winford 2010). However, one question that has received comparatively less attention is how a newly adopted loanword relates to the structure of the existing lexicon it enters. In recent years, language contact research has thus seen a paradigm shift towards an onomasiological perspective (see Anderson et al. 2017; Crombez et al. 2022; Zenner et al. 2023). Within this approach, most studies looking at lexical variation between loanwords and their (near-)synonyms employ corpus linguistics methods (e.g. Onysko & Winter-Froemel 2011; Soares da Silva 2013). However, there is variation in how these corpus studies have investigated loanword meanings, and, to our knowledge, there has been almost no experimental research focussed specifically on the relationship between loanwords and their (near-)synonyms to date. This project presents a large-scale experimental approach from a case-study examining Māori loanwords borrowed into New Zealand English (NZE). NZE presents an unusual language contact situation because it involves a dominant language (NZE) receiving an exceptionally high amount of lexical material (words and phrases) from an Indigenous language: Māori. Further adding to the uniqueness of this contact situation is the fact that only a fraction of the population (<10%) speaks Māori fluently (Statistics New Zealand 2019). Nonetheless, Māori loanwords are ubiquitous, salient, and probably still increasing within the NZE lexicon (Macalister 2007; Trye et al. 2019). One important dimension of this set of borrowings are their semantic characteristics, which straddle three main classes of words: flora and fauna (mānuka ‘tea tree’), material culture (maunga ‘mountain’) and social culture (mana ‘power’).  Here, we report on a Qualtrics experiment devised to probe the perceived relationship between 60 Māori loanwords and their NZE equivalents, as ascertained from published sources. The synonymy judgements were elicited for pairs (e.g. whānau – family) using an analogue slider (ranging from 0 = non-synonymous to 100 = fully synonymous). Data was collected using a three-tiered questionnaire: 1) assessing synonymy of loanwords; 2) eliciting strategies for semantic assessments; and 3) collating background information about participants. Following cleaning and exclusions, the dataset showed a skew towards female participants, and for this reason, we focus our statistical analysis on the core sample containing (n = 170) young women (18-24 years). The results of the synonymy judgements analysis consist of qualitative inspections of box plots in relation to the semantic characteristics of Māori words in question, as well as sociodemographic variables of interest, specifically: years lived in Aotearoa NZ, and a composite score capturing exposure to and attitude towards Māori (TRMO). Preliminary findings suggest that many people think Māori loanwords are (highly) synonymous with NZE lexical alternatives. Our regression analyses exhibit evidence that years lived in Aotearoa NZ (p = 0.0054) and TRMO (p = 8.26e-10) can predict knowledge of Māori words. No statistically significant evidence was found for any predictors regarding the scores of the synonymy judgements; instead, we found that the random effects account for most of the variation. This is indicative of idiosyncratic loanword behaviour, in line with situations where variation is in-flux. These findings will be complemented by qualitative analyses of comments provided by participants in the open answer section (2). The talk will conclude with a summary of contributions to the general understanding of loanword meanings and contact-induced lexical change.
