Tracking Bronze Age ‘itinerant smiths’ in western Poland: insights from Nd and Sr isotope data

open access: yesArchaeometry, EarlyView.
Abstract The neodymium (Nd) isotope composition of stone casting moulds found in graves of Bronze Age ‘itinerant smiths’ in western Poland was analysed to determine the provenance of their raw materials. For the first time in archaeological research, the Nd model age (TDM)—a highly useful parameter in studying the provenance of geological materials—has

Accessory minerals: a provenancing tool for steatite quarries

open access: yesArchaeometry, EarlyView.
Abstract Steatite has been a widely traded material across a range of archaeological contexts. Yet, challenges inherent to determining its provenance limits our understanding of the networks and mechanisms of its exchange. We present a robust new accessory mineral provenancing “fingerprint” method based their specific growth history.

Enhancing stone provenance studies through software built with language model artificial intelligence (AI): An example of ancient Calabrian quarries (southern Italy)

open access: yesArchaeometry, EarlyView.
Abstract This study represents the first attempt to develop archaeometric software that enables researchers without programming knowledge to address archaeometric challenges, specifically determining the provenance of rocks extracted from ancient quarries.

Volcanically induced glacier collapses in southern Jan Mayen (Sør‐Jan), Norway

open access: yesBoreas, EarlyView.
A formerly unknown glacier totally covered with tephra was found in an area of Jan Mayen where no Holocene glaciation was known. This glacier and three others in the same area melted abruptly creating jökulhlaups due to volcanic activity impacting the glacier catchments at different times in the Holocene.

Once bitten, twice shy: The overgeneralization trap and epistemic learning after policy failure

open access: yesPolitics &Policy, Volume 50, Issue 6, Page 1177-1202, December 2022., 2022
Abstract Why do smart policy makers who try to learn from policy failure end up overgeneralizing these lessons when facing new crises? This article focuses on the policy learning that can come in the wake of perceived policy failure, and the consequences that lesson learning has for diagnosing and tackling subsequent crises.

Lateglacial and Holocene glacier variations in an active volcanic area, northern Jan Mayen (Nord‐Jan), Norway

open access: yesBoreas, EarlyView.
Glacier evolution and environmental changes in the northern Jan‐Mayen from the early deglaciation and well into the Holocene are discussed. Results are based on a large chronological dataset (TCN and radiocarbon dates), integrated with field data on glacial landforms and sediments, including the use of GPR.

Spontaneous and pharmacologically induced hypothermia protect mice against endotoxic shock

open access: yesBritish Journal of Pharmacology, EarlyView.
Background and Purpose Despite the well‐known occurrence of hypothermia during sepsis, its underlying biological nature and adaptive value remain debated. Experimental Approach Using indirect calorimetry, telemetry, thermal gradient studies and pharmacological studies, we examined the thermal and metabolic responses of mice treated with a shock ...
