Clearing the Air: How Fine Particulate Matter Regulations Reshape Farmland Values in U.S. Corn and Soybean Regions

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT We investigate the impact of air quality regulations targeting fine particulate matter (PM2.5) on farmland values in corn and soybean producing counties in the United States over the period 1997–2022. Using self‐reported farmland value data from the Agricultural Census and county‐level pollution classifications provided by the Environmental ...

In for a penny: An empirical study of earthquake experience and non‐pharmaceutical intervention effectiveness in the Marche region

open access: yesAnnals of Public and Cooperative Economics, EarlyView.
Abstract This study investigates whether prior exposure to natural disasters influenced individual compliance with non‐pharmaceutical interventions (NPIs), specifically lockdown measures, during the Corona Virus Infectious Disease 2019 (COVID‐19) pandemic. Focusing on the Marche region of Italy, which experienced a severe earthquake in 2016, we exploit

Traditional and Geometric Morphometrics and Invariant Shape Descriptors of Catfish Otoliths in the Yucatán Peninsula: Tools for Species Identification and Individual Size Estimation at Maya Archaeological Sites

open access: yesArchaeometry, EarlyView.
ABSTRACT This study investigates the use of otolith shape analysis for species identification and size estimation in Ariopsis felis and Bagre marinus, based on 181 modern otoliths obtained from a scientific collection and recent sampling in the coastal regions of Campeche and Yucatán, as well as 39 archaeological otoliths corresponding to the Early ...

Exploring dietary adaptations in Ursus minimus: a 3D geometric morphometric analysis of the mandible

open access: yesBoreas, EarlyView.
Using 3D geometric morphometrics, the dietary adaptations of the extinct Auvergne bear (Ursus minimus) are analysed. Its mandibular morphology aligns more closely with omnivorous rather than insectivorous bears, challenging current ideas. The extinct bear Ursus minimus, which lived in Europe during the Pliocene and possibly Early Pleistocene, is ...

FluidMap: Proportional and Spatially Consistent Layout Enrichments in Multidimensional Projections

open access: yesComputer Graphics Forum, EarlyView.
FluidMap faithfully represents the frequency of an attribute and preserves spatial consistency. Current space‐filling methods over‐ or under‐represent attribute categories (i.e., all Voronoi‐based methods), sacrifice spatial consistency (i.e., Nmap) or both (i.e., Voronoi‐MWα).

SDFs from Unoriented Point Clouds using Neural Variational Heat Distances

open access: yesComputer Graphics Forum, EarlyView.
We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from unoriented point clouds. We first compute a small time step of heat flow (middle) and then use its gradient directions to solve for a neural SDF (right). Abstract We propose a novel variational approach for computing neural Signed Distance Fields (SDF) from ...

The plasticisation model of dye diffusion: Part 8

open access: yesColoration Technology, EarlyView.
Abstract Re‐evaluation using the Williams–Landel–Ferry equation, of exhaustion/rate of dyeing/fixation data previously reported for and acid dye, natural dye and two reactive dyes on three different types of silk substrate revealed that thermally activated dye diffusivity is governed by the thermally regulated structural relaxation times of the ...

Closed‐Form Optimal Investment Under Generalized GARCH Models

open access: yesEuropean Financial Management, EarlyView.
ABSTRACT This paper introduces a new class of stochastic volatility models for asset prices, the generalized Heston Nandi GARCH (GHN‐GARCH), with the primary objective of optimal dynamic asset allocation under expected utility theory for constant relative risk aversion investors. We study some of its theoretical properties, and demonstrate that the GHN‐

Exposure to Left‐Tail Risk, Risk Appetite, and Mutual Fund Flows

open access: yesFinancial Review, EarlyView.
ABSTRACT Using a measure of aggregate tail risk, we show that a fund's sensitivity (exposure) to tail risk negatively affects the fund flows and the fund's performance. Further, a fund's tail risk sensitivity relates positively to the left‐tail risk measures of the fund.

The Legacy of Policy Inaction in Climate‐Growth Models

open access: yesInternational Economic Review, EarlyView.
ABSTRACT To better understand the structure and core mechanisms of a broad class of climate‐growth models, we study a simplified version of the dynamic integrated model of climate and the economy (DICE) through the lens of growth theory. We analytically show that this model features a continuum of saddle‐point stable steady states.
