Ascetics, slaves, and necessity in Late Antiquity: renouncing all wealth, but for a single slave

open access: yesEarly Medieval Europe, EarlyView.
Slave owners in Late Antiquity viewed the possession of at least one slave to be a necessity and a defining mark that distinguished the dignified social classes from the poor. Ascetics who shared this perspective faced a choice when renouncing all worldly possessions in pursuit of spiritual perfection, one not merely about luxury, but also about status

Triple Oxygen Isotope Compositions of Isotopic Reference Waters: Implications for VSMOW‐Scale and VSMOW–SLAP‐Scale Δ′17O Calibration

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Triple oxygen isotope ratios of two primary (VSMOW, SLAP) and twelve secondary water isotopic reference materials were precisely measured using BrF5 fluorination‐IRMS. The measured Δ'17OVSMOW value for SLAP (34 ± 6 per meg) demonstrates that VSMOW‐SLAP normalisation ensures interlaboratory comparability, but introduces systematic offsets for

Can you really change your stripes? Stable wing ornamentation suggests limited condition‐dependent signalling in female common eiders

open access: yesIbis, EarlyView.
Variation in the expression of white ornaments, such as flank spots or wing stripes, has previously been related to indices of individual quality in birds. We measured the white wing stripes of colour‐banded female common eiders Somateria mollissima in three islands in Iceland from 2014 to 2023, to determine whether the expression of these ornaments is

Dietary flexibility and high arthropod availability prevent food limitation in a mountain population of breeding Northern Wheatears

open access: yesIbis, EarlyView.
Mountain ecosystems are under strong environmental pressure and are considered highly vulnerable to climate change, which is likely to lead to forest expansion and loss of open alpine grasslands, threatening many specialized species. However, for most alpine birds, even basic ecological knowledge, such as their diet, remains limited, restricting our ...

Climate Change, Demand Uncertainty, and Firms' Investments: Evidence from Planned Power Plants

open access: yesThe Journal of Finance, EarlyView.
ABSTRACT How does demand uncertainty affect firms' investment decisions? We examine this question in the context of electricity‐producing firms' planned investments in new power plants. We measure uncertainty about future electricity demand using plausibly exogenous variation in temperature projections across scientific climate models. The results show

Enforcing intellectual property rights in metaverse gaming platforms: The next steps for the EU's metaverse agenda

open access: yesThe Journal of World Intellectual Property, EarlyView.
Abstract This article delineates a comprehensive framework for the achievement of effective metaverse governance that reflects the EU's current metaverse agenda and promotes respect for intellectual property rights. To do so, this article follows a two‐strand methodology. It engages in a doctrinal legal analysis and a policy‐oriented assessment.

Dam Management in the Era of Climate Change

open access: yesMathematical Finance, EarlyView.
ABSTRACT Climate change has a dramatic impact, particularly by concentrating rainfall into a few short periods, interspersed with long dry spells. In this context, the role of dams is crucial. We consider the optimal control of a dam, where the water level must neither exceed a designated safety threshold nor fall below a minimum level to ensure ...

Plant genotypic diversity and defoliation jointly shape root exudation, fungal communities, and carbon and nitrogen cycling

open access: yesNew Phytologist, EarlyView.
Experimental design. Summary Intraspecific plant diversity is a major component of community diversity, yet its role in shaping plant–microbial interactions and soil functioning remains poorly understood. In particular, plant genotypic diversity may modulate ecosystem responses to defoliation, a key driver of ecosystem processes in grazed systems.
