CARMA Approximations and Estimation

Frontiers in Applied Mathematics and Statistics, 2020
CARMA(p, q) processes are compactly defined through a stochastic differential equation (SDE) involving q + 1 derivatives of the Lévy process driving the noise, despite this latter having in general no differentiable paths.

When Norms Meet Markets: Environmental Governance and Digital Fast‐Fashion Platforms in Brazil

Sustainable Development, EarlyView.
ABSTRACT Environmental governance increasingly relies on consumer‐based mechanisms that assume that sustainability awareness translates into purchasing behaviour. This article investigates whether such mechanisms remain effective when consumption is organised through transnational digital platforms in contexts characterised by socioeconomic inequality.

Synchronization transitions and spike dynamics in a higher-order Kuramoto model with Lévy noise

Communications Physics
Synchronization in complex networks is influenced by higher-order interactions and non-Gaussian perturbations, yet their mechanisms remain unclear. We investigate the synchronization and spike dynamics in a higher-order Kuramoto model subjected to Lévy ...

Balancing allocative and dynamic efficiency with redundant R&D allocation: The role of organizational proximity and centralization

Strategic Management Journal, EarlyView.
Abstract Research Summary Resource‐based‐view scholars have mainly examined two resource allocation approaches for competitive advantage in multiunit firms: resource sharing and resource redeployment. These approaches emphasize allocative efficiency—the optimal allocation of resources to maximize their current value. In technology‐intensive industries,

Abattoir antemortem inspection protocol: Observation of unloading improves detection of transport welfare compromises in livestock

Veterinary Record, EarlyView.
Abstract Background Ensuring livestock welfare throughout the production chain, including transport, is an ethical and regulatory imperative. However, protocols to assess transport‐related welfare during routine abattoir inspections are not standardised, including antemortem (AM) inspection by an official veterinarian at UK abattoirs.

Averaged Systems of Stochastic Differential Equations with Lévy Noise and Fractional Brownian Motion

Fractal and Fractional
In some problems, partial differential equations are reduced to ordinary differential equations. In special cases, when incorporating randomness, equations can be reduced to systems of stochastic differential Equations (SDEs).

Ed Davey's Tory Removals: The Liberal Democrats and the 2024 General Election

The Political Quarterly, Volume 96, Issue 1, Page 83-90, January/March 2025.
Abstract The 2024 general election represented a remarkable comeback for the Liberal Democrats. Less than a decade on from the coalition and the 2015 election debacle, Sir Ed Davey's party reclaimed third‐party status in the House of Commons with seventy‐two MPs—the largest total for the Liberal Democrats or their Liberal Party predecessors since the ...

REPRODUCING OPERATIONAL LANDSCAPES: The Rock Mining for Indonesia's New Capital City

International Journal of Urban and Regional Research, EarlyView.
Abstract Indonesia's new capital city is designed to become a green and sustainable city. In this article, we examine the (un)sustainability of the process through which the city is coming into being. Using the sociospatial theory of planetary urbanization, we trace the dialectical relationship between the new city and sites beyond it to show how ...

On a Fractional SPDE Driven by Fractional Noise and a Pure Jump Lévy Noise in ℝd

Abstract and Applied Analysis, 2014
We study a stochastic partial differential equation in the whole space x∈ℝd, with arbitrary dimension d≥1, driven by fractional noise and a pure jump Lévy space-time white noise. Our equation involves a fractional derivative operator. Under some suitable

Sailing Through Time: Building Pacific Maritime Resilience

Global Policy, EarlyView.
ABSTRACT This article examines the Pacific Blue Shipping Partnership (PBSP), an ambitious initiative aimed at decarbonising maritime transport across Oceania. The study explores the cultural, historical and technological aspects of wind‐propelled shipping in the Pacific.
