Relaxation approximations and bounded variation estimates for some partial differential equations
Electronic Journal of Differential Equations, 2002 In this paper, we introduce a new technique for studying solutions of bounded variation for some conservation laws of first order partial differential equations and for some degenerate parabolic equations in multi-dimensional space.

Two Shades of Green? Gender Differences in Environmental Concern and Activism
International Journal of Finance &Economics, EarlyView.ABSTRACT This study examines gender differences in environmental concern and activism using data from the World Values Survey. The results indicate that women are more likely than men to be concerned about the environment, but are less likely to engage in environmental activism.

International Journal of Finance &Economics, EarlyView.ABSTRACT This study investigates the impact of green bonds on environmental sustainability for a panel of 15 countries from 2014 to 2024, using the load capacity factor (LCF) as the main proxy for environmental quality, with biocapacity, ecological footprint, and CO2 emissions per capita used as additional environmental indicators.

Integrative Conservation, EarlyView.Through systematic price collection and correction for underreporting and undetected seizures, the global illegal wildlife trade (IWT) is estimated at US$28.4–39.5 billion per year. This finding highlights that previous valuations were underestimates.

A new approach to the theory of heat conduction with finite wave speeds
Le Matematiche, 1991 Relations between the physical models describing the heat conduction in solids and a phenomenological model leading to quasi-linear hyperbolic equations and systems of conservation laws are presented.

On a Nonlinear Hyperbolic–Elliptic System Modeling Chemotaxis
MathematicsIn this paper, we study a hyperbolic–elliptic system with L1-initial data, which arises as a mathematical model for chemotaxis. In particular, after introducing the notion of entropy solutions in this setting, we prove results concerning the existence of

Characterising City Scale Heat Climatology for Australian Climate Zones
International Journal of Climatology, EarlyView.The Urban Heat Island (UHI) effect in Australian cities peaks at night, intensifying under dry conditions, clear skies, increased solar radiation, and low wind speeds. Long‐term observations show that nighttime temperatures in major cities have warmed faster than their rural surroundings and future climate projections fail to capture this disparity ...

Seabird population responses after the removal of an introduced predator
The Journal of Wildlife Management, EarlyView.We studied the response of a breeding population of seabirds (pigeon guillemots) to the removal of an introduced population of predators (American mink) from an archipelago that was formerly the largest aggregation of nesting guillemots in Prince William Sound, Alaska.

Land Degradation &Development, EarlyView.ABSTRACT As the global tourism industry confronts the existential imperatives of the Anthropocene, the remediation of degraded landscapes through regenerative economic models has emerged as a critical frontier in sustainability science. This research presents a rigorous empirical examination of the “restoration–revenue” paradigm, investigating the ...
