Investigating relationships among strontium, barium, and seasonality in wild baboons

open access: yesArchaeometry, EarlyView.
Abstract Geochemical profiles of Australopithecus africanus and baboon teeth show fluctuating trace elements, possibly reflecting seasonal diets. Here we use laser ablation–inductively coupled plasma–mass spectrometric measurements of calcium‐normalized strontium and barium ratios (Sr/Ca and Ba/Ca) and ion microprobe analyses of oxygen isotopes (δ18O ...

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Does Digitalization Widen Labor Income Inequality?

open access: yesInternational Economic Review, EarlyView.
ABSTRACT We develop a growth model that endogenizes the occupational choice of workers with different ability levels to study how digitalization affects labor income inequality. The framework incorporates digitalization's multifaceted effects on the economy: (i) it influences economic growth through automation, and (ii) it affects labor income ...

Environmental Concerns and the Perceived Effectiveness of Fines and Incentives in Municipal Waste Management

open access: yesKyklos, EarlyView.
ABSTRACT Survey responses to environmental policy instruments may capture perceived behavioral effectiveness rather than abstract normative approval. This paper examines how environmental concern and information channels are associated with the selection of fines and incentives as measures that could encourage more frequent separate waste collection ...
