David Marsden's Comparative and Theoretical Craft: Signposts to a Better World of Work

British Journal of Industrial Relations, EarlyView.
ABSTRACT David Marsden enriched and extended the field of employment relations with his interdisciplinary and comparative practice. This introduction to the special issue honouring his work examines the nature of David's contribution and analyses his influence on employment relations and adjacent fields.

Weak Gravitational Lensing by a Sample of X-Ray Luminous Clusters of Galaxies -- II. Comparison with Virial Masses

, 2002
Dynamic velocity dispersion and mass estimates are given for a sample of five X-ray luminous rich clusters of galaxies at intermediate redshifts (z~0.3) drawn from a sample of 39 clusters for which we have obtained gravitational lens mass estimates.

Middle to Late Pleistocene landscape evolution and glacial dynamics in the Eastern Alps: the Gröbminger Mitterberg record, Austria

Boreas, EarlyView.
Glacial erosion during the Last Glacial Maximum (LGM) has removed much evidence of earlier glaciations and interglacials in the European Alps. At Gröbminger Mitterberg (GM), beneath a blanket of LGM till, a distinctive sediment archive preserves deposits predating the LGM.

Cosmology with Weak Lensing Surveys

, 2005
Weak gravitational lensing surveys measure the distortion of the image of distant sources due to the deflections of light rays by the fluctuations of the gravitational potential along the line of sight.

Weak gravitational lensing with CO galaxies [PDF]

, 2018
Optical weak lensing surveys have become a powerful tool for precision cosmology, but remain subject to systematic effects that can severely bias cosmological parameter estimates if not carefully removed. We discuss the possibility of performing complementary weak lensing surveys at radio/microwave frequencies, using detections of CO-emitting galaxies ...

How Early Trauma Shapes CEO Risk Appetite for Public Debt Versus Bank Debt

Financial Review, EarlyView.
ABSTRACT This study examines the impact of CEOs’ early disaster experiences on the choice of debt structure. We find that firms led by CEOs who have endured disasters are more inclined to shift from bank debt to public debt. This evidence remains robust across various alternative measures, empirical specifications, and identification tests aimed at ...

Precision Measurement of Large Shear Signals

The Astrophysical Journal Letters
So far, estimators of galaxy shape distortions are only carefully studied perturbatively in the case of small shear signals, mainly for weak-lensing science.

Current status of weak gravitational lensing

New Astronomy Reviews, 2002
Weak gravitational lensing of distant galaxies by foreground structures has proven to be a powerful tool to study the mass distribution in the universe. Nowadays, attention has shifted from clusters of galaxies to the statistical properties of the large scale structures and the halos of (field) galaxies. These applications have become feasible with the

Heritage language learners' language availability and choice: A case study of primary school Persian learners in Australia

Foreign Language Annals, EarlyView.
Abstract This study investigates the factors influencing Persian language learning among heritage language learners in Sydney, Australia, with a particular focus on how formal and informal settings shape language choice and availability. The research employs a qualitative case study approach, incorporating data from student focus groups, semi ...
