Demographic buffering in natural populations: A multi‐level perspective
Journal of Animal Ecology, EarlyView.We introduce a multi‐level framework that unites stochastic elasticities with nonlinear selection to test demographic buffering. Applying it across mammals reveals a key insight: ecological robustness to variability often decouples from evolutionary constraint, reshaping how we understand resilience under environmental stochasticity.

Pricing and hedging of Asian options: Quasi-explicit solutions via Malliavin calculus [PDF]
, 2011 We use Malliavin calculus and the Clark-Ocone formula to derive the hedging strategy of an arithmetic Asian Call option in general terms. Furthermore we derive an expression for the density of the integral over time of a geometric Brownian motion, which ...

British Journal of Educational Psychology, EarlyView.Abstract Background & Aims Mathematics anxiety impairs student learning, particularly affecting girls. Grounded in interpersonal theory, this study investigated how interpersonal teacher behaviours in student‐teacher dyads relate to boys' and girls' mathematics anxiety. We defined these behaviours using an interpersonal circumplex, which blends agency (

Filtering systems of coupled stochastic differential equations partially observed at high frequency [PDF]
, 2007 We consider online analysis of systems of stochastic differential equations (SDEs), from high-frequency data. The class of SDEs we focus on have constant volatility and a drift function that is of gradient form.

Dutch disease, unemployment and structural change
Economic Inquiry, EarlyView.Abstract We find that Dutch disease effects on unemployment are small even in a commodity‐rich economy like Australia. Using an estimated open‐economy model with frictional unemployment, we quantify how business‐cycle shocks and structural changes shape aggregate unemployment.

The big impact of small change: Fresh estimates of English wheat market integration, 1693–1893
The Economic History Review, EarlyView.Abstract Using existing and new price data sets, we provide the first estimates of market integration across England over the entire 200 years of the industrial revolution. We document a significant, though not huge, integration improvement for markets furthest from London. Full integration was achieved by the 1830s. Our price data sets vary in quality

Geostandards and Geoanalytical Research, EarlyView.Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...
