On Relative Tractor Bundles

Symmetry, Integrability and Geometry: Methods and Applications
This article contributes to the relative BGG-machinery for parabolic geometries. Starting from a relative tractor bundle, this machinery constructs a sequence of differential operators that are naturally associated to the geometry in question. In many situations of interest, it is known that this sequence provides a resolution of a sheaf that can ...

The Art of Reception: Field Visits as Microcosms for Development Interventions of Non‐Governmental Organisations in Uganda

Journal of International Development, EarlyView.
ABSTRACT Field visits are common phenomena with non‐governmental organisations in Uganda. During these visits, Ugandan national staff guide visitors on series of meetings and interactions in the field. Following an actor‐oriented approach and drawing on ethnographic data on 14 field visits, this paper understands the field visit as a microcosm for the ...

Soil Loosening of Compacted Urban Tree Sites Using a Pneumatic Lance Injector: Quantifying Treatment Success Through Tree Morphology and Soil Structure Parameters via Terrestrial Laser Scanning

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Urban trees provide essential ecosystem services, but their growth and longevity are often limited by soil compaction. Although pneumatic lance injection (PLI) is increasingly promoted as a minimally invasive and efficient soil loosening technique, but robust scientific evidence for its long‐term effectiveness remains limited.

Reshaping Labor Intermediation: An Integrated Workforce Management Strategy to Contrast Agricultural Workers' Exploitation in Italy

Strategic Change, EarlyView.
ABSTRACT Labor exploitation within agri‐food supply chains poses significant ethical and managerial challenges, particularly in Mediterranean contexts where irregular employment practices persist. This study investigates the case of NoCap, a third‐party ethical certification initiative operating in Italy that integrates social responsibility into ...

A fuzzy-QFD approach for the enhancement of work equipment safety: a case study in the agriculture sector [PDF]

, 2018
The paper proposes a design for safety methodology based on the use of the Quality Function Deployment (QFD) method, focusing on the need to identify and analyse risks related to a working task in an effective manner, i.e.

Botanical treatment enhances biochemical responses in enset (Ensete ventricosum (Welw.) Cheesman) clones

JSFA reports, EarlyView.
Abstract Background Bacterial wilt of enset (Ensete ventricosum (Welw.) Cheesman) is a severe disease caused by Xanthomonas campestris pv. musacearum, resulting in complete crop failure and considerable damage. This study assessed the biochemical responses of two enset clones (one resistant and one susceptible) when inoculated with the pathogen and ...
