Year‐round colony‐level differences in foraging behaviour and diel activity of yellow‐legged gulls from natural and urban colonies

open access: yesJournal of Zoology, EarlyView.
GPS‐tracked yellow‐legged gulls from urban (Porto) and natural (Berlenga) colonies showed contrasting foraging strategies. Urban gulls remained near cities and followed human routines, while natural gulls foraged farther and used marine habitats. Abstract Urbanisation has led to increased populations of opportunistic species like gulls, driven by the ...

Subtleties Concerning Conformal Tractor Bundles

open access: yes, 2012
The realization of tractor bundles as associated bundles in conformal geometry is studied. It is shown that different natural choices of principal bundle with normal Cartan connection corresponding to a given conformal manifold can give rise to ...

Luigi Pasinetti and Adolph Lowe: Bridging Capital Theory and Institutional Analysis

open access: yesMetroeconomica, EarlyView.
ABSTRACT This article examines the convergence of Luigi Pasinetti's and Adolph Lowe's political economy, linking capital theory, institutions, and normative methodology. Pasinetti's two‐stage approach and Lowe's instrumental method share a common emphasis on the structural requirements and institutional arrangements for attaining and maintaining full ...

Due Diligence Regulation and Sustainability Governance in Value Chains: Lessons From the South African Wine Sector

open access: yesRegulation &Governance, EarlyView.
ABSTRACT A recent raft of due diligence regulation (DDR) addressing social and environmental conditions in global value chains (GVCs) has spread across the UK and Europe. An emerging literature on DDR highlights the politics of its formation. Yet, we know little about how existing sustainability governance along GVCs interacts with DDR or the wider ...

Testing the Assumptions of History‐Dependent Approaches to Regulation: Comparing Compliant Companies With Those That Transgress

open access: yesRegulation &Governance, EarlyView.
ABSTRACT Risk‐based approaches to regulatory governance are ubiquitous. One aspect of such approaches suggests regulators direct their attention towards companies that have already violated regulations. However, such approaches have made little use of available data to explore these companies, especially compared to companies that do not transgress ...

Mathematical Modeling and Mechanism of Coarsening of Austenitic Grain at High-Temperature Heating of Alloyed Structural Steels

open access: yesМеханика машин, механизмов и материалов, 2019
The influence of the heating rate of typical cemented steels 15KhGN2TA and 25KhGT on the growth of austenitic grain at long isothermal exposures in the process of high-temperature chemical-thermal treatment is studied.
