Harmonizing Community Science Datasets to Model Highly Pathogenic Avian Influenza (HPAI) in Birds in the Subantarctic

Littauer, Richard, Bubendorfer, Kris

arXiv.org Artificial Intelligence

Community science observational datasets are useful in epidemiology and ecology for modeling species distributions, but the heterogeneous nature of the data presents significant challenges for standardization, data quality assurance and control, and workflow management. In this paper, we present a data workflow for cleaning and harmonizing multiple community science datasets, which we implement in a case study using eBird, iNaturalist, GBIF, and other datasets to model the impact of highly pathogenic avian influenza in populations of birds in the subantarctic. We predict population sizes for several species where the demographics are not known, and we present novel estimates for potential mortality rates from HPAI for those species, based on a novel aggregated dataset of mortality rates in the subantarctic.


Air New Zealand tests a new generation of electric planes

Popular Science

Battery and hydrogen-powered aircraft are cleared for takeoff. Breakthroughs, discoveries, and DIY tips sent every weekday. Air New Zealand has cleared its runways to test both all-electric and hydrogen-powered planes . Although in its early stages, the four-month "intensive proving program" may help one day usher in a new era of sustainable flight. Aircraft remain some of the biggest sources of vehicle-based pollution in the world.


'Cool and quirky is part of our brand': how New Zealand became a hothouse for indie games

The Guardian

Standing out in a crowded market: many of the best titles at Pax Australia in Melbourne came from New Zealand game developers. Standing out in a crowded market: many of the best titles at Pax Australia in Melbourne came from New Zealand game developers. 'Cool and quirky is part of our brand': how New Zealand became a hothouse for indie games T hose not immersed in the world of gaming might not be familiar with Pax Australia: the enormous gaming conference and exhibition that takes over the Melbourne Convention and Exhibition Centre every October. My favourite section is always Pax Rising, a showcase of indie video games and tabletop, the majority Australian - but there has been a recent shift that was particularly notable this year: many of the standout titles had crossed the Tasman, arriving from New Zealand . At the booth run by Code - New Zealand's government-funded Centre for Digital Excellence - 18 Kiwi developers demoed their forthcoming games in a showcase of the vibrant local scene that was buzzing with crowds.


Generalisation Bounds of Zero-Shot Economic Forecasting using Time Series Foundation Models

This study investigates zero-shot forecasting capabilities of Time Series Foundation Models (TSFMs) for macroeconomic indicators. We apply TSFMs to forecasting economic indicators under univariate conditions, bypassing the need for train bespoke econometric models using and extensive training datasets. Our experiments were conducted on a case study dataset, without additional customisation. We rigorously back-tested three state-of-the-art TSFMs (Chronos, TimeGPT and Moirai) under data-scarce conditions and structural breaks. Our results demonstrate that appropriately engineered TSFMs can internalise rich economic dynamics, accommodate regime shifts, and deliver well-behaved uncertainty estimates out of the box, while matching state-of-the-art multivariate models on this domain. Our findings suggest that, without any fine-tuning, TSFMs can match or exceed classical models during stable economic conditions. However, they are vulnerable to degradation in performances during periods of rapid shocks. The findings offer guidance to practitioners on when zero-shot deployments are viable for macroeconomic monitoring and strategic planning.


Rare seabird saved after swallowing four large fishhooks

Veterinarians successfully removed the debris from the juvenile Salvin's albatross. Breakthroughs, discoveries, and DIY tips sent every weekday. A rare seabird is recovering from a successful and life-saving surgery. A fisherman from Anconcito, Ecuador, found the juvenile Salvin's albatross after he noticed that it appeared unwell. The bird had ingested four large fishing hooks and some fishing line and was brought to Puerto Lopez for rehabilitation and care.


World's only flightless parrot doing okay against 'crusty bum' disease

Popular Science

New Zealand's critically endangered kākāpō are not showing signs of antibiotic resistance. Breakthroughs, discoveries, and DIY tips sent every weekday. With only 237 birds left in the wild, saving New Zealand's critically endangered kākāpō is one of the small country's major conservation projects. These giant, green camouflage experts are threatened by predators, invasive species, human encroachment, and a debilitating illness colloquially called crusty bum disease (exudative cloacitis). Birds that contract it can become infertile, which puts strain on their already small populations.



The Complexity of Extreme Climate Events on the New Zealand's Kiwifruit Industry

Climate change has intensified the frequency and severity of extreme weather events, presenting unprecedented challenges to the agricultural industry worldwide. In this investigation, we focus on kiwifruit farming in New Zealand. We propose to examine the impacts of climate-induced extreme events, specifically frost, drought, extreme rainfall, and heatwave, on kiwifruit harvest yields. These four events were selected due to their significant impacts on crop productivity and their prevalence as recorded by climate monitoring institutions in the country. We employed Isolation Forest, an unsupervised anomaly detection method, to analyse climate history and recorded extreme events, alongside with kiwifruit yields. Our analysis reveals considerable variability in how different types of extreme event affect kiwifruit yields underscoring notable discrepancies between climatic extremes and individual farm's yield outcomes. Additionally, our study highlights critical limitations of current anomaly detection approaches, particularly in accurately identifying events such as frost. These findings emphasise the need for integrating supplementary features like farm management strategies with climate adaptation practices. Our further investigation will employ ensemble methods that consolidate nearby farms' yield data and regional climate station features to reduce variance, thereby enhancing the accuracy and reliability of extreme event detection and the formulation of response strategies.


Stronger Together: Unleashing the Social Impact of Hate Speech Research

Wong, Sidney

arXiv.org Artificial Intelligence

The advent of the internet has been both a blessing and a curse for once marginalised communities. When used well, the internet can be used to connect and establish communities crossing different intersections; however, it can also be used as a tool to alienate people and communities as well as perpetuate hate, misinformation, and disinformation especially on social media platforms. We propose steering hate speech research and researchers away from pre-existing computational solutions and consider social methods to inform social solutions to address this social problem. In a similar way linguistics research can inform language planning policy, linguists should apply what we know about language and society to mitigate some of the emergent risks and dangers of anti-social behaviour in digital spaces. We argue linguists and NLP researchers can play a principle role in unleashing the social impact potential of linguistics research working alongside communities, advocates, activists, and policymakers to enable equitable digital inclusion and to close the digital divide.


Riverside wants to become 'the new Detroit.' Can this self-driving electric bus get it there?

Los Angeles Times

There is a little shuttle bus in the Inland Empire that's fueled with big aspirations. It's electric, tops out at 25 mph, and can only go on a pre-designated route set up by the Riverside Transit Agency. But here's a catch -- it also drives itself. As of Monday, commuters in Riverside are the first in the country to ride a fully self-driving, publicly accessible bus that is deployed by a city transit agency. "I like to say I have no lesser ambition than to be the new Detroit for vehicle manufacturing," Riverside Mayor Lock Dawson said.
