Correcting Left‐Truncation Bias in Weibull Reliability Analysis: Synthetic Data Validation for Electrical Utility Assets

Quality and Reliability Engineering International, EarlyView.
ABSTRACT Incomplete historical records in utility asset datasets frequently introduce left‐truncation bias, leading to distorted reliability estimates and suboptimal asset management decisions. This study presents a systematic framework for validating left‐truncation correction in Weibull reliability analysis using synthetic data representative of ...

Co‐Design to Capacity: An Instructional Design Approach for Indigenous Women Empowerment and Sustainable Technology Adoption

Sustainable Development, EarlyView.
ABSTRACT The adoption of rural livelihood technologies is often hindered by a gap between participatory design and user capacity. This study addresses this challenge with a co‐designed lemongrass distillation system in rural India that remained unused due to a lack of community capacity, despite a successful design process.

National Policy Coherence Counts for Reducing Inequality in Global Climate and Development Agendas

Sustainable Development, EarlyView.
ABSTRACT International institutions promote policy coherence as crucial to the effective and fair implementation of global sustainability agendas, though the evidence for its benefits is slim. We present here the first systematic cross‐country dataset on the consequences of national government efforts to promote policy coherence for vulnerable groups ...

Cultivating Sustainability: How Modern Food Practices Shape Pro‐Environmental Motivation Through Food–Nature Associations

Sustainable Development, EarlyView.
ABSTRACT Food practices have evolved alongside industrialization and urbanization. Compared to earlier generations, modern individuals grow and cook food less often and consume more processed products, weakening awareness of food's natural origins. Three studies examined explanatory pathways linking food practices to pro‐environmentalism through the ...

Affordable and Clean Energy: CO2 Emissions, Resilience and Inequality

Sustainable Development, EarlyView.
ABSTRACT Sustainable development means building the resilience of both people and the planet. It includes implementing strategies which reduce emissions while also enabling more vulnerable households to transition to clean and affordable energy. This paper examines household CO2 emissions in Ireland to highlight those who emit most and least in key ...
