Preferential trading in agriculture: New insights from a structural gravity analysis and machine learning

American Journal of Agricultural Economics, EarlyView.
Abstract Preferential trade agreements (PTAs) contain various non‐tariff provisions, yet identifying their trade effects remains challenging because these commitments are high‐dimensional and strongly correlated within agreements. We estimated a theory‐consistent structural gravity model with domestic flows for 26 agricultural subsectors over 1988–2017

Linking the atmospheric Pacific-South American mode with oceanic variability and predictability

Communications Earth & Environment, 2021
South Pacific atmospheric variability can excite a sea surface temperature quadrupole pattern in the extra-tropics that acts as a precursor for the South Pacific decadal oscillation and ENSO, according to reanalysis data and model output.

Exposure to heat waves and drought improves subsequent leaf heat tolerance for five oak species in southern California

American Journal of Botany, EarlyView.
Abstract Premise Given the threats of climate change, we investigated the impact of high temperatures separately and in combination with reduced soil water on leaf heat tolerance for five oaks (Fagaceae) with overlapping ranges in southern California, USA: Quercus agrifolia and Q. chrysolepis (evergreen species), Q. douglasii and Q.

Multi-decadal variability of sea surface temperature and phytoplankton in the subpolar North Atlantic: insights from observation and model

, 2013
This thesis investigates the physical controls of variability in phytoplankton abundance in the subpolar North Atlantic. A multi-decadal set of monthly SST data (HadISST1) is used to identify the dominant variability in the SST annual cycle during the ...

Long-term sea surface temperature variability in the Aegean Sea [PDF]

, 2011
The inter-annual/decadal scale variability of the Aegean Sea Surface Temperature (SST) is investigated by means of long-term series of satellite-derived and in situ data. Monthly mean declouded SST maps are constructed over the 1985–2008 period, based on

Intensified Manufactured Non‐Belonging: Working Holiday Makers in Australia During the COVID‐19 Pandemic

Australian Journal of Social Issues, EarlyView.
ABSTRACT Nations manufacture non‐belonging of temporary migrants through policy frameworks that produce exclusion. This precarity maximises the economic benefit of temporary migrant labour by minimising their political, social and legal rights. In this paper, we examine how non‐belonging targeting Working Holiday Makers (WHMs) is manufactured in ...

Dynamical and biogeochemical control on the decadal variability of ocean carbon fluxes [PDF]

Earth System Dynamics, 2013
Several recent observation-based studies suggest that ocean anthropogenic carbon uptake has slowed down due to the impact of anthropogenic forced climate change.

Sea-level change and storm surges in the context of climate change [PDF]

, 2000
This paper reviews the latest research in New Zealand surrounding the issues of sea-level rise and extreme sea levels in the context of global warming and variability in the Pacific-wide El Nino– Southern Oscillation (ENSO).

The fossil record stays silent: Confusions and conundrums for hominin pelvis evolution

The Anatomical Record, EarlyView.
Abstract The evolution of the hominin pelvis is commonly modeled as a series of stages driven largely by the requirements of bipedal locomotion, reproduction, thermoregulation, and pelvic floor muscular support. These patterns are complicated by variation in canal dimensions in relationship with different changes in overall pelvic breadths. To quantify

Craniofacial growth, modeling, and estimation of milestones

The Anatomical Record, EarlyView.
Abstract Understanding craniofacial growth is foundational for research into intra‐ and interspecies variation, evolution, and clinical care. The Craniofacial Growth Consortium Study (CGCS), combines cephalographs from historical growth studies to create a dense longitudinal record of growth from 6 to 22 years of age.
