Population Size and Cultural Evolution in Nonindustrial Food-Producing Societies
Modeling work suggests that population size affects cultural evolution such that larger populations can be expected to have richer and more complex cultural repertoires than smaller populations. Empirical tests of this...
Risk of Resource Failure and Toolkit Variation in Small-Scale Farmers and Herders
Recent work suggests that global variation in toolkit structure among hunter-gatherers is driven by risk of resource failure such that as risk of resource failure increases, toolkits become more diverse and complex. Here we...
Geometric Morphometric Analyses Support Incorporating the Goshen Point Type into Plainview
Recent work has demonstrated that Goshen points overlap in time with another group of unfluted lanceolate points from the Plains, Plainview points. This has raised the question of whether the two types should be kept separate or...

A Morphometric Assessment of the Intended Function of Cached Clovis Points
A number of functions have been proposed for cached Clovis points. The least complicated hypothesis is that they were intended to arm hunting weapons. It has also been argued that they were produced for use in rituals or in...

An Assessment of the Impact of Hafting on Paleoindian Point Variability
It has long been argued that the form of North American Paleoindian points was affected by hafting. According to this hypothesis, hafting constrained point bases such that they are less variable than point blades. The results of...

The earth's electromagnetic environment
It is found that the energy density of electromagnetic fields at the surface of the Earth follow a scaling law that extends over 16 orders of magnitude from 10-9 Hz to 107 Hz. The temporal variability of the field can be...

Dynamic exergy analysis
C Michalakakis, JM Cullen
Jul 28, 2021
As the power and transport sectors decarbonize, industrial emissions will become the main focus of decarbonization efforts. Exergy analysis provides a combined material and energy efficiency approach to assess industrial plants...

Partisan Gerrymandering and the Illusion of Unfairness
JM Eisler
Aug 22, 2017
Partisan gerrymandering is frequently condemned for distorting democracy and causing unfair representation, and many reformers have called upon federal courts to prohibit the practice. However, the judiciary has struggled to...
