Digital Transformation and Informal Innovation in Africa: Reframing STI Policy for Inclusive Circular Economy Transitions

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Amid increasing environmental and economic pressures, Africa's transition to a circular economy (CE) presents a vital pathway to inclusive, low‐carbon development. Yet, how digital transformation, informal innovation, and science, technology, and innovation (STI) policy readiness shape CE outcomes remains underexplored.

Carbon Footprint of Bank Loans: Opportunities and Risk Implications in the Banking Industry

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines whether the carbon footprint of bank loan portfolios influences bank stability, profitability and cost efficiency and whether regulatory quality moderates these relationships. Using a balanced panel of 33 countries from 2005 to 2018, the analysis combines banking‐sector indicators from the World Bank Global Financial ...

Equatorial spread F and interplanetary magnetic field.

open access: yesJournal of geomagnetism and geoelectricity, 1977
A reversal of the vertical F region drifts over the magnetic equator during the nighttime hours from the normal downward direction to upward direction is shown to cause the sudden generation of the Range type spread F configuration on the ionograms after a delay of about one hour.

Sustainable and Resilient Supply Networks: Digitalisation, Regulation and Climate Vulnerability in a Global Context

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The growing frequency of global crises has intensified concerns regarding climate vulnerability and the resilience of global production systems. This study examines the heterogeneous effects of supply chain development and supply chain digitalisation on climate vulnerability across countries, while accounting for institutional and investment ...

HF radar observations of equatorial spread-F over West Africa

open access: yesAnnales Geophysicae
New experimental data depicting equatorial spread-F were taken during an HF radar sounding campaign in Korhogo (Ivory Coast, 9°24N, 5°37W, dip 4°S). Range-time-intensity maps of the radar echoes have been analyzed to identify the signatures of density ...

Environmental, Social and Governance (ESG) Drivers of Sustainability Transitions in Sub‐Saharan Africa: Why One Size Does Not Fit All

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Despite growing emphasis on sustainability transitions in developing economies, evidence remains limited on how environmental, social and governance (ESG) conditions shape sustainability outcomes in sub‐Saharan Africa (SSA). This study examines the environmental, social and governance drivers of sustainability transition performance across 39 ...

Modified Neumann incision for implant placement in overdentures: Case series of a less invasive alternative

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Conventional envelope flap techniques for implant placement in edentulous mandibles are associated with greater postoperative morbidity, especially in elderly patients or those with anatomical limitations. Minimally invasive alternatives aim to preserve soft tissues and reduce complications, enhancing clinical predictability ...

Features of 3–7-day planetary-wave-type oscillations in F-layer vertical drift and equatorial spread F observed over two low-latitude stations in China

open access: yes, 2017
. Recent studies on the equatorial atmosphere–ionosphere coupling system have shown that planetary-wave-type oscillations, as an important seeding mechanism for equatorial spread F (ESF), play an important role in ESF irregularity development and its day-

Linear Programming Optimization of Nutritional and Technological Properties in Wheat Bread Fortified With Taioba (Xanthosoma sagittifolium L.) Leaf Flour

open access: yesCereal Chemistry, EarlyView.
ABSTRACT Background and Objectives This study applied linear programming to optimize taioba (Xanthosoma sagittifolium) leaf flour (TLF) incorporation in wheat bread, balancing nutritional enrichment and technological quality. Findings Breads containing 0%–15% TLF (flour basis) were produced and evaluated for composition, dough expansion, specific ...

A Bio‐Based Chiroptical Overcrowded Alkene From Flavanone: Photoreactivity and Theoretical Investigation

open access: yesChemistry – A European Journal, EarlyView.
A sustainable route to photoresponsive molecular systems is achieved using the bio‐based flavanone (‐)‐isolonchocarpin from Tephrosia vogelii. Through McMurry homocoupling and light‐driven 6‐π‐electrocyclization, an overcrowded alkene and a fluorescent O‐heterocyclic phenanthrene are synthesized.
