Two Regimes of Waste and Value: ‘Post‐Disaster’ Landscapes in a New India

Development and Change, EarlyView.
ABSTRACT In this age of ‘disaster capitalism’, catastrophes are neither ‘natural’ nor ‘external’. They are political events mediating and vitally shaping the unequal and exploitative use of environmental resources. India's ‘post‐disaster’ landscapes at the turn of the new millennium powerfully demonstrate how visions of the new‐normal can be imposed in

Stock Market Response to Private Corruption: The Moderation Role of Public Perceptions

European Financial Management, EarlyView.
ABSTRACT This study examines how corporate corruption events affect stock returns among European firms, focusing on the moderating role of public sector corruption perceptions measured by the Corruption Perceptions Index (CPI). Using over 25,000 firm‐level events from 2007 to 2022, the study finds that corruption events lead to negative abnormal ...

Six Ca‐Mg‐Fe Carbonate Reference Materials for In Situ Measurement of Oxygen and Carbon Isotope Ratios

Geostandards and Geoanalytical Research, EarlyView.
Key Points Six new Ca‐Mg‐Fe carbonate reference materials are available to the global geochemical community for calibrating oxygen and carbon isotope ratios by SIMS. Significant compositional matrix effects were observed in the dolomite‐ankerite and magnesite‐siderite series during SIMS analysis. Compositional matrix effects correlate with Fe variation.

New Magnetite Reference Material for SIMS δ18O Measurements and a Study of Precision and Accuracy Due to Crystal Orientation Effects

Geostandards and Geoanalytical Research, EarlyView.
Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the
