Edge Sharpness Does Not Vary Between Palaeolithic Flake Technologies, With the Possible Exception of Levallois Débitage

open access: yesArchaeometry, EarlyView.
ABSTRACT Investigating why hominins adopted particular flake technologies during the Mid‐to‐Late Pleistocene is essential to understanding patterns of lithic innovation. This period witnessed the emergence of Levallois technologies (~350–250 ka) and later blades, each “replacing” earlier forms.

Effects of Combining Eco‐ and Social Labels on Consumer Value—Additive, Neutral or Cannibalizing? Insights From a Conjoint Analysis

open access: yesBusiness Ethics, the Environment &Responsibility, EarlyView.
ABSTRACT Despite research on sustainable labels, little is known about combining eco‐ and social labels and the effects on consumers. Although consumers are increasingly confronted with both socially oriented, e.g., fair trade, as well as environmentally oriented eco‐labels such as certified organic cotton, the effect on consumer value has not been ...

Effects of prematurity and socio‐economic status on early life language exposure: A video coding study

open access: yesBritish Journal of Developmental Psychology, EarlyView.
Abstract Preterm birth is associated with later language impairment and delay. Socio‐economic deprivation is linked to decreased language exposure in early childhood, but it is unknown how prematurity influences this relationship. This study investigated the effects of socio‐economic status and gestational age at birth on language exposure, in a sample

Morphology and distribution of lakes under the Laurentide Ice Sheet: implications for ice flow dynamics

open access: yesBoreas, EarlyView.
This study examines the distribution and morphology of lakes under the Laurentide Ice Sheet (LIS) to investigate relationships with ice flow velocity, bedrock and basal thermal regime. Palaeo‐ice streams and lobes were important components of the LIS, and properties of lakes in those regions are quantified at high resolution.
