Government-Sourced Categorical Economic Policy Uncertainty
(Elsevier BV, 2026-10-14) Hoang, Khanh; Pham, Linh; Ngo, Thanh; Dao, Thuy; Do, Hung; Doan, Hieu; Duong, An; Ha, Oanh; Huynh, Nhan; Le, Phuong; Le, Trung; Mai, Chi; Mai, Thoi; Nguyen, Nga; Phung, Giang; Nguyen, Tam; Nguyen, Thao; Nguyen, Thao; Truong, Ha; Vo, Diem; Vu, Harris
This study develops a novel framework for measuring Categorical Economic Policy Uncertainty (GovCEPU) by analysing textual data from official government communications rather than traditional news media. Using Vietnam as a theoretical test case, a transition economy where centralised policy signals are paramount, we construct distinct monthly indices of monetary, fiscal, and trade policy uncertainty (2004-2023). Comparative analysis reveals that GovCEPU measures capture higher volatility and provide signals of policy shifts different from news-based counterparts, reflecting ex-ante deliberation in state-led contexts. Employing a Diebold-Yılmaz (2012, 2014) connectedness framework to account for systemic endogeneity, we demonstrate that monetary and fiscal uncertainties function as primary net shock transmitters to the macroeconomic system, whereas trade policy uncertainty operates as a net receiver. At the micro-level, heightened monetary and fiscal policy uncertainty have significant impacts on banks’ loan loss provisions and risk-taking, while trade policy uncertainty impairs non-financial firms’ performance and capital expenditures. These findings suggest that government-sourced indices offer a direct, cost-effective, and theoretically grounded alternative to media-based metrics for evaluating policy-related risks in emerging markets.

Health Response to Family Violence: Violence Intervention Programme Evaluation 2025-2026
(Centre for Interdisciplinary Trauma Research, 2026-09-11) Koziol-McLain, Jane; Herbert, Sarah; Garrett, Nick; Lowe, Kathy; Ngawati, Sarah; Pukepuke, Tepora
[From "Preamble"] Building on the Violence Intervention Programme (VIP) evaluation conducted between 2020 and 2024, this report presents findings from an assessment of health system infrastructure supporting programme delivery in 2025. Data were collected through administration of the Delphi Tool during site visits undertaken across all 20 districts in Aotearoa New Zealand in 2026.

Design Considerations for a Disaster eHealth Appliance
(International Society for Telemedicine and eHealth, 2018-03-29) Parry, David; Madanian, Samaneh; Norris, Anthony
Disaster eHealth is a new area of research and endeavour. In order to make a practical contribution Disaster eHealth approaches should consider the role of a Disaster eHealth appliance. Both disaster management and disaster medicine may find that such approaches allow critical information to be gathered and situational awareness improved. This paper proposes the development of a Disaster eHealth appliance to support self-care of chronic disease and caregiving by others. Injuries and disease caused by the disaster may be also supported by this approach. It also attempts to address some of the potential problems and suggest some solutions for the use of such appliances. Re-using existing devices may offer a relatively low-cost and sustainable approach to providing such devices, and infrastructure to use them.

Flame Temperatures Saturate With Increasing Dead Material in Ulex europaeus, but Flame Duration, Fuel Consumption and Overall Flammability Continue to Increase
(MDPI AG, 2019-01-29) Dent, Jennifer; Buckley, Hannah; Lustig, Audrey; Curran, Timothy
A key determinant of wildfire behaviour is the flammability of constituent plants. One plant trait that influences flammability is the retention of dead biomass, as the low moisture content of dead material means less energy is required to achieve combustion. However, the effect of the dead-to-live ratio of fuel on plant flammability has rarely been experimentally quantified. Here we examine the nature of the relationship between dead fuel accumulation and flammability in Ulex europaeus (common gorse). Shoots with varying proportions of dead material were ignited in a purpose-built plant-burner. Three components of flammability were measured: sustainability (flame duration), consumability (proportion burnt biomass) and combustibility (maximum temperature). While flame duration and proportion burnt biomass had a positive linear relationship with the proportion of dead material, the response of maximum temperature was positive but non-linear. All three flammability components were reduced to a single variable using principal components analysis; this had a non-linear relationship with the proportion of dead material. The response of maximum temperature to dead material plateaued at 39%. These findings have implications for the management of habitats invaded by gorse; to mitigate fire hazard associated with gorse, stands should be kept at a relatively young age when dead fuel is less prevalent.
