Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe

Archaeometry, EarlyView.
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Partition regularity of Pythagorean pairs

Forum of Mathematics, Pi
We address a core partition regularity problem in Ramsey theory by proving that every finite coloring of the positive integers contains monochromatic Pythagorean pairs (i.e., $x,y\in {\mathbb N}$ such that $x^2\pm y^2=z^2$ for some $z ...

Learning Across the Divide: Understanding Knowledge Sharing Through Petrographic Analysis on Ceramics From the Rhine‐Meuse Delta During the Middle to Late Neolithic Transition (3400–2200 bce)

Archaeometry, EarlyView.
ABSTRACT Vlaardingen (VL) communities on the Dutch West coast (3400–2200 bce) are part of a unique, long‐term continuity in the European Neolithic. Despite large‐scale changes in European populations during the Neolithic, the genomic diversity and cultural practices of VL communities can be retraced to the Mesolithic.

Discrimination in autism as measured by minimal group and sheer difference experiments

British Journal of Psychology, EarlyView.
Abstract Autistic individuals often show fewer social biases than neurotypical people. Whether they show fewer discriminatory tendencies is however unclear. The present study examined discriminatory tendencies in autistic versus neurotypical individuals in the minimal group paradigm and the novel ‘sheer difference’ paradigm.

Beyond Sporting Talent: Other Determinants of Football Clubs’ Wage Bills

Bulletin of Economic Research, EarlyView.
ABSTRACT This article delves into the understanding of how football clubs determine wage bills to compensate talent. Using data from first‐division teams in elite European leagues, we estimate wage models based on indicators of sporting performance, “Elo ratings” as a proxy for clubs’ historical achievements and brand strength, and “media visibility ...

The commercialization of labour markets: Evidence from wage inequality in the Middle Ages

The Economic History Review, EarlyView.
Abstract This paper moves beyond the focus on ‘average’ wage trends in pre‐industrial economies by examining the broad diversity of pay rates and forms of remuneration across occupations and regions in medieval England. We find that whilst some workers enjoyed substantial growth in wage rates after the Black Death, there was a large group who ...

Collectively enhanced Ramsey readout by cavity sub- to superradiant transition

Nature Communications
When an inverted ensemble of atoms is tightly packed on the scale of its emission wavelength or when the atoms are collectively strongly coupled to a single cavity mode, their dipoles will align and decay rapidly via a superradiant burst.
