Insights From the Alphasat Aldo Paraboni Experiment at Tito Scalo and Spino d'Adda: Characterizing Scintillation and Rain Attenuation at Ka‐ and Q‐Band Frequencies

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT We present experimental results on the relationship between rain attenuation and simultaneous scintillation during rain events, based on beacon signal measurements at 19.7 (Ka‐band) and 39.4 GHz (Q‐band) from the geosynchronous Alphasat satellite (25° E), received at two Italian ground stations, Spino d'Adda (42.1° slant path) and Tito Scalo ...

From Innovation to Sustainability: Integrating Fintech, Green Trade and Knowledge Systems for Circular Growth in Sub‐Saharan Africa

Sustainable Development, EarlyView.
ABSTRACT The transition toward circular and sustainable growth remains a major challenge in Sub‐Saharan Africa (SSA), where resource constraints, limited recycling capacity, and infrastructure deficits constrain environmental performance. Drawing on circular economy and innovation systems perspectives, this study examines how financial technology ...

AI Vibrancy and Renewable Energy Consumption: A Cross‐Country Analysis

Sustainable Development, EarlyView.
ABSTRACT This study examines the association between artificial intelligence vibrancy and renewable energy consumption across 36 countries from 2017 to 2023. Using a reduced‐form panel framework with Driscoll–Kraay standard errors, the results show that income per capita and government effectiveness are the dominant drivers of renewable energy ...

How Climate Change Shapes Environmental, Social, and Governance (ESG) Performance in the MENA Countries

Sustainable Development, EarlyView.
ABSTRACT Climate change, political stability, and sustainability are three central factors that interact and serve as key drivers of achieving the Sustainable Development Goals (SDGs) in the MENA (Middle East and North Africa) region. Accordingly, this paper aims to fill a vital research gap by examining the impacts of climate change, natural resource ...
