Liberate or Subjugate Them? The Effect of Supplier Dependence on Buyer Innovation

Journal of Product Innovation Management, EarlyView.
ABSTRACT This study extends the current understanding of buyer–supplier relationships (BSRs) and innovation by investigating the supplier dependence—buyer innovation relationship. Drawing from resource dependence and exploration‐exploitation perspectives, we hypothesize that supplier dependence negatively affects buyer innovation performance, and that ...

Testing gravitational physics by combining DESI DR1 and weak lensing datasets using the E_G estimator

The Open Journal of Astrophysics
The action of gravitational physics across space-time creates observable signatures in the behaviour of light and matter. We perform combined-probe studies using data from the Baryon Oscillation Spectroscopic Survey (BOSS) and Dark Energy Spectroscopic ...

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.

Ellipticities of Galaxy Cluster Halos from Halo–Shear–Shear Correlations

The Astrophysical Journal
We report the first detection of the halo ellipticities of galaxy clusters by applying the halo–shear–shear correlations (HSSCs), without the necessity of using major axis determination.

Weak gravitational lensing with SKA

, 1999
I shall outline the basic principles and some observational aspects of weak gravitational lensing, and discuss several applications of this powerful tool in observational cosmology. It will be explained why the applications have been restricted to optical observations up to now, and why SKA is going to change this. I conclude with a few general remarks

Lensing Magnification and QSO-Galaxy Cross-Correlations: Observations, Theory and Simulations

, 2005
We review observations and gravitational lensing theory related to the magnification of background QSOs by intervening overdensities, and the induced cross-correlation between sources and foreground galaxies.
