The Construction of an Environmental Villain: A Discourse Analysis of Upland Maize Farming in Thailand

open access: yesAsia Pacific Viewpoint, EarlyView.
ABSTRACT Since the mid‐2010s, Thai public discourse has villainised upland maize cultivation in northern Thailand for deforestation and environmental degradation through the popular imagery of bald mountains. The attention has prompted a new wave of land‐use interventions urging upland smallholders to replace maize with trees and perennials.

Lithic analysis in African archaeology: Advances and key themes

open access: yesArchaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

Basal body temperature as a biomarker of reproductive state in ewes: A multi‐method comparison

open access: yesAustralian Veterinary Journal, EarlyView.
This study quantified body temperature dynamics throughout reproductive stages in crossbred ewes based on complementary monitoring techniques. Five ewes from a semi‐extensive farming system were included in two sub‐trials: animals were first assessed in the prepubertal stage and, subsequently, an oestrous cycle was induced by intravaginal progesterone ...

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

open access: yesBoreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

FluidMap: Proportional and Spatially Consistent Layout Enrichments in Multidimensional Projections

open access: yesComputer Graphics Forum, EarlyView.
FluidMap faithfully represents the frequency of an attribute and preserves spatial consistency. Current space‐filling methods over‐ or under‐represent attribute categories (i.e., all Voronoi‐based methods), sacrifice spatial consistency (i.e., Nmap) or both (i.e., Voronoi‐MWα).
