Abstract The borrowing of words from one language into another is most likely as ancient as language itself. While ample linguistic attention has focused on various linguistic contact scenarios in which words from one language enter productive use into another, their aim has been largely restricted to documenting the words which are borrowed, their frequency, and other situation-specific information. In this paper, we propose new methods for studying loanwords, namely a combination of statistical testing techniques which can be used together to increase knowledge in this area. We illustrate these tools with a case-study of loanwords from an indigenous language (Māori) into a world dominant language (New Zealand English). Using a topic-constrained newspaper corpus in conjunction with quantitative methods, we explore the use of loanwords diachronically and analyse variation in loanword use across newspapers and across writers.

Shed Light

ABSTRACTIn studying language change, variationists are, naturally perhaps, more interested in the new, innovative form than in the old conservative one, and because of the actuation problem, investigations of changes in progress very rarely are able to shed light on the change in its very earliest stages. In this article, I suggest that we should perhaps pay more attention than we have at present to the origins of the change (in addition to its route and destination) and the nature of the conservative form if we are to chart ongoing changes in an accurate way. Here, I highlight an example of a feature of New Zealand English (NZE) (realizations of the mouth diphthong with front mid-open onsets) that has, until recently, been assumed to have resulted from a change of the Southern Shift-kind—a raising and fronting to [εʊ~εƏ]—but which, as I demonstrate using contemporary and past dialectological, as well as sociodemographic evidence, did not undergo this change in this way. Indeed, the supposedly conservative [aʊ] form has barely been used at all as a conversational vernacular variant in NZE. I argue here that the present-day NZE realization is far more likely to be the outcome of a process of dialect leveling operating on the mixture of forms brought to New Zealand by British and Irish migrants in the 19th century. The moral of the story is that if we think we observe a change in progress from A to B, we need to provide evidence not just of the existence of B, but also of the prior existence of A.

William Smyth, unable to get work in a New Zealand museum, ran a commercial taxidermy business at Caversham, Dunedin, from about 1873 to 1911 or 1912. His two decades of correspondence with Thomas Frederic Cheeseman at the Auckland Museum provide a case study of Smyth's professional interaction with one of New Zealand's main museums. We have used this and other sources to paint a picture of Smyth's activities and achievements during a time when there was great interest in New Zealand birds but few local taxidermists to preserve their bodies. Besides the Auckland Museum, Smyth supplied specimens to various people with museum connections, including Georg Thilenius (Germany) and Walter Lawry Buller (New Zealand). Smyth was probably self-taught, and his standards of preparation and labelling were variable, but he left a legacy for the historical documentation of New Zealand ornithology by the large number of his bird specimens that now reside in public museum collections in New Zealand and elsewhere.

<p>In medicinal chemistry programs it is key to design and make compounds that are efficacious and safe. This is a long, complex and difficult multi-parameter optimization process, often including several properties with orthogonal trends. New methods for the automated design of compounds against profiles of multiple properties are thus of great value. Here we present a fragment-based reinforcement learning approach based on an actor-critic model, for the generation of novel molecules with optimal properties. The actor and the critic are both modelled with bidirectional long short-term memory (LSTM) networks. The AI method learns how to generate new compounds with desired properties by starting from an initial set of lead molecules and then improve these by replacing some of their fragments. A balanced binary tree based on the similarity of fragments is used in the generative process to bias the output towards structurally similar molecules. The method is demonstrated by a case study showing that 93% of the generated molecules are chemically valid, and a third satisfy the targeted objectives, while there were none in the initial set.</p>

This chapter uses two case studies to explore how historians study language movement and change through comparative historical linguistics. The first case study stands as a short chapter in the larger history of the expansion of Bantu languages across eastern, central, and southern Africa. It focuses on the expansion of proto-Kafue, ca. 950–1250, from a linguistic homeland in the middle Kafue River region to lands beyond the Lukanga swamps to the north and the Zambezi River to the south. This expansion was made possible by a dramatic reconfiguration of ties of kinship. The second case study explores linguistic evidence for ridicule along the Lozi-Botatwe frontier in the mid- to late 19th century. Significantly, the units and scales of language movement and change in precolonial periods rendered visible through comparative historical linguistics bring to our attention alternative approaches to language change and movement in contemporary Africa.

A complete understanding of the occurrence of microplastics and the methods to eliminate their sources is an urgent necessity to minimize the pollution caused by microplastics. The use of plastics in any form releases microplastics to the environment. Existing policy instruments are insufficient to address microplastics pollution and regulatory measures have focussed only on the microbeads and single-use plastics. Fees on the use of plastic products may possibly reduce their usage, but effective management of plastic products at their end-of-life is lacking. Therefore, in this study, the microplastic–failure mode and effect analysis (MP–FMEA) methodology, which is a semi-qualitative approach capable of identifying the causes and proposing solutions for the issue of microplastics pollution, has been proposed. The innovative feature of MP–FMEA is that it has a pre-defined failure mode, that is, the release of microplastics to air, water and soil (depending on the process) or the occurrence of microplastics in the final product. Moreover, a theoretical recycling plant case study was used to demonstrate the advantages and disadvantages of this method. The results revealed that MP–FMEA is an easy and heuristic technique to understand the failure-effect-causes and solutions for reduction of microplastics and can be applied by researchers working in different domains apart from those relating to microplastics. Future studies can include the evaluation of the use of MP–FMEA methodology along with quantitative methods for effective reduction in the release of microplastics.

Important Research Question

The rights-of-nature model is gaining traction as an innovative legal approach for nature conservation. Although adopted in several countries, it remains in its infancy, including in Australia. An important research question is whether rights of nature will offer superior environmental outcomes compared to traditional nature conservation techniques including creation of protected areas. This article investigates that question through a case study of the Tarkine wilderness, in the Australia state of Tasmania. It first identifies key lessons from existing international experience with affirmation of rights of nature, such as in New Zealand and Ecuador. The article then explores how rights of nature could apply in Australia’s Tarkine region and their value compared to existing or potential protected areas and other nature conservation measures under Australian or Tasmanian law. Affirming rights of nature represents a major conceptual shift in how people via the law relate to the natural world, but whether the model offers practical benefits for nature conservation depends on a variety of conditions, in addition to the need to address broader societal drivers of environmentaldegradation.

The deuterium excess in precipitation is an effective indicator to assess the existence of sub-cloud evaporation of raindrops. Based on the synchronous measurements of stable isotopes of hydrogen and oxygen (δ2H and δ18O) in precipitation for several sites in Lanzhou, western China, spanning for approximately four years, the variations of deuterium excess between the ground and the cloud base are evaluated by using a one-box Stewart model. The deuterium excess difference below the cloud base during summer (−17.82‰ in Anning, −11.76‰ in Yuzhong, −21.18‰ in Gaolan and −12.41‰ in Yongdeng) is greater than that in other seasons, and difference in winter is weak due to the low temperature. The variations of deuterium excess in precipitation due to below-cloud evaporation are examined for each sampling site and year. The results are useful to understand the modification of raindrop isotope composition below the cloud base at a city scale, and the quantitative methods provide a case study for a semi-arid region at the monsoon margin.
