Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

open access: yesArchaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Transhumanism Without Transindividuation in the Age Without Epochality: Stiegler, Vice, and Radical Human Enhancement

open access: yesBioethics, EarlyView.
ABSTRACT At its core, transhumanism is utopic and apocalyptic: it tells us we will be saved through an imminent radical change of our being wrought by radical human enhancement (RHE) technologies. We are rushing, its supporters claim, towards a technological utopia so long as assorted techno‐phobes do not stand in the way.

Mixture multigroup structural equation modelling for ordinal data

open access: yesBritish Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Social scientists often compare groups in terms of relations between latent variables (LV) (i.e. structural relations) using Structural Equation Modelling (SEM). LVs are measured indirectly by questionnaires; thus, measurement invariance must be evaluated before comparisons can be made. To efficiently compare many groups, the recently proposed
