Atypical Long Barrows in the Cöeby Neolithic Cemetery (Trédion, Morbihan, France)? The Contribution of Electrical Surveys

Archaeological Prospection, EarlyView.
ABSTRACT The Coëby Neolithic cemetery, located in the commune of Trédion (Morbihan, France) and discovered in 1986, has been for several years the subject of a research programme focused on studying the various megalithic structures present. The spatial distribution of these remains highlights an unusual occupation of the territory, organized according

Deciphering the Palimpsest: Chronological Uncertainty and the Interpretation of Mining Landscapes at Písečný vrch (Czech Republic)

Archaeological Prospection, EarlyView.
ABSTRACT We investigated the Písečný vrch (Czech Republic), a site exploited for quartz mining in both prehistoric times and the 20th century. Due to their morphological similarity across all mining periods, the differentiation between pits with archaeological potential and recent ones is challenging.

Racial gaps without racism: How English universities frame inequality in access and participation plans

British Educational Research Journal, EarlyView.
Abstract Racial inequalities are pervasive in higher education despite concerted efforts to redress issues of access, progression and continuation. Little attention has been paid to how universities themselves construct race within their policy texts.

Mapped Legendre collocation methods for linear Volterra–Fredholm integral equations with delays on a semi-infinite interval

Mathematical Modelling and Analysis
In this paper, we present a collocation method for linear Volterra–Fredholm integral equations with delay on a semi-infinite interval. The method employs orthogonal mapped Legendre basis functions together with a mapped Gauss quadrature rule adapted to ...
