The Roads To and From Serfdom [PDF]

The institution of slavery displays a puzzling historical pattern: it is found mostly at intermediate stages of agricultural development, in horticultural societies, and less frequently among hunter-gatherers and societies at more advanced agrarian ...

World prehistory from the margins: the role of coastlines in human evolution [PDF]

, 2004
Conventional accounts of world prehistory are dominated by land-based narratives progressing from scavenging and hunting of land mammals and gathering of plants to animal domestication and crop agriculture, and ultimately to urban civilisations supported

Epstein–Barr Virus, Lower Vitamin D, Low Sun Exposure, and HLA‐DRB1*1501 Risk Variant Share Common Epigenetic Pathways Leading to Multiple Sclerosis Onset

Annals of Neurology, EarlyView.
Objectives Multiple sclerosis (MS) onset risk factors include Epstein–Barr virus (EBV) indices (including host response), lower serum 25‐vitamin D (25(OH)D) levels, low sun exposure, and HLA‐DRB1*1501. The underlying molecular mechanisms are unclear. Here, we examined mediation through differential DNA methylation (DNAm) to better understand possible ...

Evolutionary Echoes: A Four-Day Fasting and Low-Caloric Intake Study on Autonomic Modulation and Physiological Adaptations in Humans

Life
This study evaluates the psychophysiological response to a simulated hunter–gatherer endurance task with restricted caloric intake over four days. It assesses changes in body composition, autonomic modulation, and physical and cognitive performance ...

Mechanistic Insights Into Photocatalytic Materials for Toxic Pollutants: Environmental Remediation of Personal Care Products

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Photocatalytic materials have emerged as promising solutions for environmental applications due to their ability to degrade organic pollutants under sunlight or artificial light. In this review, recent progress on the photocatalytic materials used for the degradation of pharmaceutical personal care products (PPCPs) in environmental ...

Where goods are free but knowledge costs: Hunter-gatherer ritual economics in Western Central Africa [PDF]

, 2015
Forest hunter-gatherers in Western Central Africa participate in an unusual economic system that transacts material production in a very different way to intellectual production. While material goods, such as food, tools or clothing, are generally freely

Membrane Polymers for the Pervaporative Separation of Polar Organics: Methanol and Acetonitrile

Journal of Applied Polymer Science, EarlyView.
We tested seven polymers as membranes for the pervaporative separation of methanol‐acetonitrile mixtures. Chloroprene rubber, silicone rubber, and Matrimid showed effective separation by favoring acetonitrile transport, enabling azeotrope breaking. Plasticization was assessed using Broadband Dielectric Spectroscopy.
