Continuous Tracking and Recognition of Small Objects in Video Streams Based on YOLO and Spatio-Temporal Contextual Memory Networks

open access: yesSensors
Small objects in video streams occupy a small proportion in the image; the texture and shape information they carry is limited, making it difficult to continuously track and identify.

Circular Economy in Food Supply Chains: Comprehending the Paradigm and Redefining Future Research Through a Multidisciplinary Review of Reviews

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT The inefficiencies of the global food system necessitate a shift towards a circular economy (CE) in food supply chains (FSCs). While research on CE in FSCs spans multiple disciplines, it often remains siloed within respective disciplinary boundaries, limiting its practical impact.

Corporate‐Community Land Governance for Peace: A Governance Materiality Framework for CSR, ESG, and Sustainable Agribusiness

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Within corporate social responsibility (CSR) and environmental, social, and governance (ESG), there is a gap. This paper aims to fill that gap by building on a previous empirical study. It introduces the Land Governance Materiality Framework (LGMF), which redefines land governance as a critical governance skill that impacts ESG performance ...

Spatial variation in liana effects on host‐tree allometry and biomass in an intact tropical forest

open access: yesEcography, EarlyView.
Lianas are increasing in abundance across the tropics, yet local spatial variation in their effects on host‐tree allometry and biomass, and the drivers of this variation within forests, remain poorly understood. Using field inventory, drone photogrammetry, and terrestrial laser scanning (TLS) across a 50‐ha plot on Barro Colorado Island, Panama, we ...
