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 ...

Revealing Hidden Impact: Social and Solidarity Economy Enterprise Networks and Sustainable Development in Developing Countries

Sustainable Development, EarlyView.
ABSTRACT The Social and Solidarity Economy (SSE) offers strong potential for sustainable development in low‐income regions, yet its enterprises often operate with scarce resources, weak monitoring systems, and limited visibility. These constraints hinder both their capacity to demonstrate contributions to sustainable development (SD) and their own ...

Living Through a Changing Climate: Stress, Trauma, and Gendered Resilience Among Women in Coastal and Northern Ghana

Sustainable Development, EarlyView.
ABSTRACT Climate change is reshaping everyday life in Ghana through coastal erosion, flooding, erratic rainfall, water scarcity, extreme heat, and agricultural insecurity. This study examines how these changes produce stress, trauma, and gendered resilience among women in Salakope and Choggu Yapalsi, two climate‐vulnerable communities in coastal and ...

Beyond Growth: Governance and Education as Drivers of Environmental Health in an EKC‐Based PLS‐SEM Framework

Sustainable Development, EarlyView.
ABSTRACT Isolating environmental issues from their broader social and political context limits understanding of their true drivers. In this sense, factors such as governance and education can be powerful determinants of environmental performance. This research examines the factors influencing the Environmental Health component of the Environmental ...
