ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...

Can Credit Rating Changes Affect Corporate Carbon Emissions? Some Evidence From the S&P 500
ABSTRACT Using panel data on US S&P 500 firms from 2012 to 2024, this study examines how credit rating changes affect corporate carbon performance. Drawing on the resource‐based view and prospect theory, we show that credit rating downgrades lead to a statistically and economically significant deterioration in emission reduction scores.

Effect of Thermal Ageing on the Electrical Insulation Properties of the Oil-Paper Insulation
The article focuses on the electrical insulation properties of oil-paper insulation and its application in practice at AC voltage. It also discusses the effect of moisture and thermal ageing on the breakdown strength and breakdown voltage of oil-paper combinations.

Do Commodity Prices and Energy Markets Drive Asymmetric Volatility in Biodiversity Finance?
ABSTRACT This study examines symmetric and asymmetric volatility spillovers among biodiversity finance, commodity prices, and energy markets using daily data from 2019 to 2025. We apply the Diebold–Yilmaz time–domain connectedness model, Baruník–Křehlík frequency–domain decomposition, and an asymmetric spillover framework.

Aging State Evaluation of Oil-Paper Insulation Based on Fusion of Gray Texture and Oil Gas Features
Aiming at the problem of insufficient precision of aging information obtained by single partial discharge(PD) feature discrimination, a D-S evidence fusion recognition method based on PD gray texture and oil-gas features is proposed to analyze the aging ...

ABSTRACT Measuring sustainability performance is crucial for small and medium‐sized manufacturing enterprises and sustainability indicators must be incorporated into decision‐making. However, companies tend to measure only the aspects that interest them, disregarding those considered less strategic or relevant.

The assessment method of transformer oil-paper insulation state based on PSO-ELM
Oil-immersed power transformer is an important part of power grid, and its reliable operation plays a vital role in pomler system security. Aiming at the problem that the insulation state of transformer cannot be assessed quantitatively after long-term ...

African Twist of Circular Economy: Insights, Policies and Recommendations
ABSTRACT While the circular economy (CE) has gained traction, this paper argues that mainstream CE approaches risk being misaligned in the African context. Drawing on a mixed‐methods synthesis of empirical studies, policy documents and cross‐country examples, the study shows that Africa's CE transition is fragmented and uneven, leaving the continent at
