The emergence and complexification of symbolic practices in the Homo lineage: an archaeological and cognitive perspective Émergence et complexification des pratiques symboliques dans la lignée Homo : une approche archéologique et cognitive

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Recent archaeological discoveries, reviewed in this essay, challenge traditional views on the emergence of human symbolic cognition. Once believed to have originated in Europe around 40,000 years ago, new evidence shows it emerged much earlier across diverse regions.

A Territorial Approach to Transitioning Oil and Gas Producing Regions: Comparative Practices and Prospects for Canada

open access: yesCanadian Public Administration, EarlyView.
Abstract Oil and gas transitions are relatively new and especially difficult because the sector is large, economically central, and deeply embedded in national energy systems. Territorial approaches—grounded in regional political economies, institutions, and community impacts—offer a politically feasible way to begin meaningful oil and gas transitions ...

ENABLING PARTIAL UPGRADING IN ALBERTA: A REVIEW OF THE REGULATORY FRAMEWORK AND OPPORTUNITIES FOR IMPROVEMENT

open access: yesThe School of Public Policy Publications, 2019
One of the ways that Alberta can help alleviate its worsening bottleneck in oilexport pipelines is by partially upgrading oil sands bitumen before shipping it to market.

Impacts of coal smoke on infant mortality: Evidence from industrializing Japan

open access: yesThe Economic History Review, EarlyView.
Abstract This study investigates the health consequences of coal smoke during Japan's early industrialization. Using fixed‐effects models and a prefecture‐level panel dataset on actual coal consumption and infant mortality from 1899 to 1910, this study finds that higher coal consumption was positively associated with infant mortality.

Climate Regulation, Firm Emissions, and Green Takeoversa

open access: yesJournal of Money, Credit and Banking, EarlyView.
Abstract We show that an unexpected tightening of the EU Emissions Trading System led high‐emission‐intensity firms to cut emissions relative to low‐intensity peers within the same industry, without reducing output, thereby improving emission efficiency. Effects are stronger for power producers than for manufacturing firms.

Early development of anoxia prior to the main euxinic phase of the Jenkyns Event on the margin of the Western Tethys (Sachrang Basin, Eastern Alps)

open access: yesSedimentology, EarlyView.
ABSTRACT Although the global expansion of oxygen‐depleted marine environments during the Early Toarcian Jenkyns Event (or Toarcian Oceanic Anoxic Event) is primarily inferred from successions in the NW European epicontinental basins, the timing of the expansion of anoxia in Tethyan basins, where hydrography potentially played a minor role, is poorly ...

Influence of rejuvenators on bitumen ageing in hot recycled asphalt mixtures

open access: yesJournal of Traffic and Transportation Engineering (English ed. Online), 2018
The use of reclaimed asphalt pavement (RAP) in new hot mix asphalt (HMA) by means of hot recycling techniques generates the advantage linked to the exploitation of both lytic and bituminous component, consequently leading to the decrease of both virgin ...
