Shaping the System Through Turbulence: Strategic Leadership and the Micro‐Foundations of Ecosystem Orchestration in Times of Disruption

Journal of Management Studies, EarlyView.
Abstract While research on ecosystems and their orchestration has grown rapidly, we still know little about how individual strategic leaders may mobilize ecosystemic action in times of disruption. This article addresses this gap by drawing on an in‐depth case study of the Antwerp Square Mile, the world’s oldest and most renowned diamond trading ...

Signatures of Electromagnetic and Sound Radiation Produced by Gravitational Waves in Core-collapse Supernovae

The Astrophysical Journal
This paper presents the scenario that gravitational waves, generated in the core collapse of a pre-supernova star, can produce both electromagnetic radiation and sound radiation as gravitational waves propagate outward from the collapsing core. While the

Why Industrial Internet of Things Platforms Fail: A Structuration Theory Perspective on Platform Evolution

Journal of Product Innovation Management, EarlyView.
ABSTRACT Despite their transformative potential, Industrial Internet of Things (IIoT) platforms often fail to evolve into scalable ecosystems. Research on IIoT platforms attributes failure to discrete factors such as governance misalignment or technological complexity and rarely considers how failure unfolds.

Determining impact angle from the spatial distribution of shock metamorphism: A case study of the Gosses Bluff (Tnorala) impact structure, Australia

Meteoritics &Planetary Science, EarlyView.
Abstract The majority of planetary impacts occur at oblique angles. Impact structures on Earth are commonly eroded or buried, rendering the identification of the direction and angle of impact—using methods such as asymmetries in ejecta distribution, surface topographic expression, central uplift structure, and geophysical anomalies—challenging. In this

Magnetic Field Amplification during a Turbulent Collapse

The Astrophysical Journal
The question of whether a dynamo can be triggered by gravitational collapse is of great interest, especially for the early Universe. Here, we employ supercomoving coordinates to study the magnetic field amplification from decaying turbulence during ...

Confirmation of the impact origin of the Late Ordovician Tvären impact structure (southeast Sweden) and emplacement of impactites in a marine setting

Meteoritics &Planetary Science, EarlyView.
Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

Polymict melt‐bearing breccia dikes in the Morokweng impact structure formed by slip‐induced mechanical mixing of pseudotachylite and cataclasite along large‐displacement impact faults

Meteoritics &Planetary Science, EarlyView.
Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

Using Cultural Theory to Specify the Policy Actors, Belief Systems, and Sources of Coalition, Conflict, Stability, and Change in Policy Advocacy Coalitions and Environmental Resource Policies

Policy Studies Journal, EarlyView.
ABSTRACT We use grid‐group cultural theory (CT) to specify underspecified aspects of the Advocacy Coalition Framework (ACF). Our theoretical synthesis of CT and the ACF provides, first, an exhaustive typology of policy actors and their cultural cognitive biases that entail, guide, and constrain policy core beliefs about problem definitions and ...

Quantum Gravitational Collapse

, 2005
We apply the recent results in Loop Quantum Cosmology and in the resolution of Black Hole singularity to the gravitational collapse of a star. We study the dynamic of the space time in the interior of the Schwarzschild radius. In particular in our simple model we obtain the evolution of the matter inside the star and of the gravity outside the region ...
