Preliminary Appraisal of a Correlation Between Glaciations and Large Igneous Provinces Over the Past 720 Million Years

open access: yesGeophysical Monograph Series, Page 169-190., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Insights from the Presidential Addresses to the Agricultural Economics Society

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT The Society's published presidential addresses have embraced a wide range of subject matter, reflecting a ‘road well travelled’ in agricultural economics. The areas covered include the development and use of data and statistics, lessons from history, sectoral analysis, land economics, international trade and international development.

Market Integration and Nonlinear Price Transmission in 19th‐Century British Wheat Markets

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Important developments in infrastructure and institutions characterized 19th‐Century wheat markets in Great Britain. Among these developments was the construction of the national rail system which enabled cheaper and more efficient transport of grain and other bulky cargoes between inland towns and ports.

New Results From the Pre‐Pottery Neolithic Site of Al Uyaynah, Tabuk, in Northwestern Saudi Arabia

open access: yesArabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Al Uyaynah is a low sandstone mound on an alluvial plain, long known for its extensive surface remains of stone‐built circular and rectangular structures. Following test excavations in 2012, more detailed excavation was undertaken in 2016 within one of the largest rectangular stone structures.

Field‐level crop choice responses to weather‐induced yield shocks in the US Corn Belt

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract As climate change increases the frequency and severity of extreme heat events, farmers are expected to face greater variability in crop yields. Using 10 million field‐level observations, this study examines how farmers in the US Corn Belt adjust corn–soybean rotation decisions in response to yield shocks largely driven by weather fluctuations.

Theories of Interest and Their Relation to the Gesell–Keynes Theory

open access: yesThe American Journal of Economics and Sociology, EarlyView.
ABSTRACT We consider theories of interest as they relate to what we will call the Gesell‐Keynes (GK) theory which is essentially a real theory of capital accumulation with a monetary constraint that arises because of a liquidity return on holding money.

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

open access: yesArchaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.

Ring‐Width Dendrochronology, Isotopic Dendrochronology and Radiocarbon Dating of Timbers From the Spire Scaffold of Salisbury Cathedral, Wiltshire, England

open access: yesArchaeometry, EarlyView.
ABSTRACT Ten timbers from the spire scaffold of Salisbury Cathedral were dated using a combination of ring‐width dendrochronology, stable oxygen isotopic dendrochronology and radiocarbon dating. Seven timbers were coeval and assigned a combined empirical felling date range of 1352–1378, which was further refined to 1351–1359 (OxCal 95.4%).

Dealing With Inbuilt Age: A Bayesian Approach to Radiocarbon Dating of Rice, Bamboo and Charcoal From Non Ban Jak, Thailand

open access: yesArchaeometry, EarlyView.
ABSTRACT New radiocarbon determinations from rice grains and bamboo have been obtained from Non Ban Jak, Northeast Thailand. These, along with charcoal, date a late Iron Age building sequence. The results come from short‐lived species and charcoal with potential inbuilt age. We built a series of Bayesian models to obtain a reliable chronology.
