Successful Implementation of Environmental Policy and Governance: Understanding and Modeling Micro Governance

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Successful implementation of environmental policy and governance highly depends on the capacity to know about, build new and utilize existing governance structures. However, the theoretical tools and available methods to assess the complexity of emerging or existing structures are rather limited.

The coevolution of board interlock networks and corporate strategic actions

open access: yesStrategic Management Journal, Volume 47, Issue 4, Page 974-1008, April 2026.
Abstract Research Summary Studies on board interlock networks are divided into two streams, one examining their dynamics; the other, their consequences. We propose that both phenomena—board interlock dynamics and consequences—are interdependent. Applying structuration theory, we explain and empirically demonstrate how firms' corporate strategic actions

Challenges facing green space: is statute the answer? [PDF]

open access: yes, 2019
Against a backdrop of austerity, characterised by public-sector funding cuts and a devolutionary agenda, this paper explores how legislation might address two, inter-related challenges which face public urban green space ('greenspace') in England and ...

A Curie Point Depth Model of the Conterminous United States Derived From a Prior‐Constrained Equivalent Source Inversion

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract The Curie Point Depth (CPD) is a key thermal boundary in the deep lithosphere and is widely used to constrain its thermal structure. However, uncertainties in magnetization and the non‐uniqueness of inversion lead to considerable inter‐study differences.

Algal glycans promote microbial turnover of organic matter through stabilization of subtidal permeable sandy sediments

open access: yesLimnology and Oceanography, Volume 71, Issue 3, March 2026.
Abstract Permeable sands on continental shelves host microbial communities that drive organic carbon turnover, oxygen fluxes and nitrogen loss. Advective porewater flow associated with sedimentary bedforms maintains these rates and fluxes. Modeling and laboratory studies suggest that advective porewater flow is tightly coupled to bedform stability ...

Determining Geological Properties by a Hybrid Seismic-Magnetotelluric Approach [PDF]

open access: yes, 2002
This paper concerns the controlled source audio magnetotelluric technique (CSAMT) for imaging subsurface structure. Given the short time available, we limited our investigation to a simple 1D earth model where regional seismic and well logs suggest ...

A Novel Iterative Stable Algorithm for Global Moho Modeling in the Spherical Harmonic Domain

open access: yesEarth and Space Science, Volume 12, Issue 12, December 2025.
Abstract The Mohorovičić discontinuity (Moho) marks the boundary between Earth's crust and the underlying mantle, serving as a critical interface for understanding Earth's structure, composition, and geodynamic processes. This study introduces a novel iterative and stable algorithm for global Moho depth inversion.

Applying Compactness Constraints to Differential Traveltime Tomography [PDF]

open access: yes, 2007
Tomographic imaging problems are typically ill-posed and often require the use of regularization techniques to guarantee a stable solution. Minimization of a weighted norm of model length is one commonly used secondary constraint.

Observations of Small‐Scale Heterogeneity in the Upper Mantle Beneath Old Oceanic Lithosphere

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract We present tomographic images of the velocity structure of the upper mantle beneath old (∼90 ${\sim} 90$ Ma) oceanic lithosphere, derived from arrival time measurements of teleseismic body waves recorded by ocean‐bottom seismometers. Differential travel time measurements on P, S, and SKS body waves across a wide range of frequency bands show ...

LCS-1: A high-resolution global model of the lithospheric magnetic field derived from CHAMP and Swarm satellite observations [PDF]

open access: yes, 2017
We derive a new model, named LCS-1, of Earth’s lithospheric field based on four years (2006 September–2010 September) of magnetic observations taken by the CHAMP satellite at altitudes lower than 350 km, as well as almost three years (2014 April–2016 ...
