Practicing Strategic Financial Sustainability in Small Cultural Non‐Profits: Evidence From London Museums

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Small cultural museums play an important role in sustaining local heritage, community identity and inclusive cultural participation, yet they face persistent financial and organisational constraints. This study examines how financial sustainability is achieved and maintained in three small cultural museums through a qualitative‐led mixed ...

Economic and environmental implications of the development of UASB reactors in Mexico for sustainable industrial wastewater treatment

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract The objective of this work is to demonstrate that the inclusion of an up‐flow anaerobic sludge bed (UASB reactor) within an industrial wastewater treatment plant reduces the plant's investment and operating costs compared to a system based solely on conventional complete‐mix activated sludge (CMAS), operating under the same design principles ...

An Ultraminiaturized Dual-Stopband Frequency Selective Surface for Ultra High Frequency

open access: yesIEEE Access, 2020
In this paper, an ultraminiaturized dual-stopband frequency selective surface (FSS) for ultra high frequency (UHF) is investigated. The proposed FSS uses one dielectric layer with two different metal layers printed on its surfaces and the metal layers ...

Beyond Prediction: Data, Baselines, Explanation, and Causation in Machine Learning for Food Insecurity

open access: yesFood Safety and Health, EarlyView.
The gains from machine learning in nowcasting and forecasting food insecurity are still small and limited and cannot be observed in all countries. This review summarizes the public resources for data, corrects common misconceptions about model requirements, and establishes baseline requirements, explanations, causal inference, and equity in operational

Improving Daily Rainfall Downscaling Over Taiwan's Complex Terrain With Surface‐Wind‐Informed Deep Learning Model

open access: yesInternational Journal of Climatology, EarlyView.
An encoder–decoder architecture (EDA) dynamically downscales coarse‐resolution climate fields (0.25°) to high‐resolution outputs (0.05°) over Taiwan, improving the representation of fine‐scale spatial variability and localized extremes by incorporating both rainfall and surface winds to maintain physical consistency.
