Burying Futures: Artisanal Mining Deaths and the Politics of Negligence in Zimbabwe

open access: yesAmerican Anthropologist, EarlyView.
ABSTRACT In the gold‐mining town of Kwekwe, central Zimbabwe, injury and death are a constant presence. Collapsing shafts, sudden explosions, gang fights, and neglected health infrastructure characterize the everyday lives of the town's impoverished residents.

Agreement between cardiac cycle time intervals and myocardial velocities measured by automated analysis of color tissue Doppler cine loops and by manual tracing of spectral pulsed‐wave tissue Doppler waveforms of sheep fetal heart under normal and pathological conditions: An experimental study

open access: yesActa Obstetricia et Gynecologica Scandinavica, EarlyView.
Automated cTDI in sheep fetuses provided reproducible measurements of myocardial velocities and heart rate that align well with manual pulsed‐wave TDI. For cardiac cycle duration metrics, the two modalities are not interchangeable. These findings support that automated cTDI is well suited for longitudinal assessment under both physiological and ...

Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Statistical power in UK genetic syndrome research; evidence from studies of Down syndrome, Fragile X syndrome and Williams syndrome as model syndrome groups

open access: yesBritish Journal of Developmental Psychology, EarlyView.
Abstract Research on genetic syndromes is vital to our understanding of how development unfolds, but the rarity of genetic syndromes can mean that studies are carried out with small sample sizes. Small sample sizes can reduce the statistical power of a study to produce reliable and replicable results.

Of eyes and hands: Assessing the evolutionarily stable strategy of human handedness by means of eye‐tracking

open access: yesBritish Journal of Psychology, EarlyView.
Abstract An evolutionarily stable strategy (ESS) suggests that the 1:9 ratio of left‐ to right‐handers in humans could reflect a frequency‐dependent equilibrium: the minority of left‐handers and the majority of right‐handers may have an advantage in competitive and cooperative circumstances, respectively.
