Alternative Contract Design: Analysing the Bankability of Fungible Derivative Contracts in Energy‐Only Markets

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT With the retirement of 21GW of legacy coal fleet looming, the task to replace Australia's thermal capacity with alternative firmed renewable ‘bulk energy’ solutions is non‐trivial. Indeed, calibrating necessary capital investment in new plant stock with efficient economic outcomes, vis‐à‐vis cost and reliability, represents a fundamental ...

Government Policy, Low‐ and High‐Skilled Labour, and Technical Inefficiency in Chinese Agriculture, 1952–2008

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT We utilize Chinese provincial data to explore how government policies affected grain production between 1952 and 2008. We adapt the Caselli‐Coleman framework to allow multiple inputs including fertilizer, land and capital as well as skilled and unskilled labour.

Metabarcoding replicate detection frequency tracks ddPCR copy number for cod and herring eDNA in ancient marine sediments

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Detecting environmental DNA (eDNA) from rare or low‐abundance aquatic species remains a major challenge, particularly when it is highly degraded, present at low concentrations, and dominated by DNA from non‐target taxa. These challenges are further amplified in sedimentary ancient DNA (sedaDNA) studies, where thousands of years can degrade ...

How teacher behaviour in student‐teacher dyads relates to boys' and girls' mathematics anxiety. An investigation of interpersonal profiles

open access: yesBritish 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 (

The big impact of small change: Fresh estimates of English wheat market integration, 1693–1893

open access: yesThe 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

Fatigue of AM TiAl6V4: Probabilistic Modelling of the Size Influence as a Transfer Method From Test Specimen to Part

open access: yesFatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This paper investigates the fatigue behavior of additively manufactured TiAl6V4 by comparing two specimen geometries with different highly stressed volumes. A fracture mechanical approach based on the El‐Haddad–Smith–Topper model is combined with defect analysis through X‐ray computed tomography.

On Integral Priors for Multiple Comparison in Bayesian Model Selection

open access: yesInternational Statistical Review, EarlyView.
Summary Noninformative priors constructed for estimation purposes are usually not appropriate for model selection and testing. The methodology of integral priors was developed to get prior distributions for Bayesian model selection when comparing two models, modifying initial improper reference priors. We propose a generalisation of this methodology to

A path‐based two‐commodity flow model and a branch‐price‐and‐cut algorithm for the inventory routing problem with time windows

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract We study an inventory routing problem with time windows (IRPTW). A single supplier serves a set of customers to fulfill their demand throughout a planning horizon. Each customer can be visited only within designated time windows, assuming each customer provides a single delivery time window valid for all periods.
