Shedding light on the environmental efficiency of the public light service: minimising light pollution through the global Malmquist–Luenberger index

open access: yesInternational Transactions in Operational Research, EarlyView.
Abstract The search for evidence in public management and the implementation of good management by public bodies is becoming increasingly important, and the principles of effectiveness and efficiency should be reinforced. Therefore, this paper aims to analyse the change in efficiency in the provision of public lighting services by local governments ...

Recovery From Anorexia Nervosa: A Concept Analysis

open access: yesJournal of Advanced Nursing, EarlyView.
ABSTRACT Aim Despite decades of research, we still know surprisingly little about how best to bring about lasting recovery from anorexia nervosa (AN). Furthermore, there is a lack of consensus in the research and treatment communities about what constitutes recovery from AN, or whether “recovery” is even an appropriate term to use in this context.

Almost billfish: convergent longirostry, micro‐dentition, and possible glandular sinuses in a large teleost fish from the Upper Cretaceous of Northern Italy

open access: yesJournal of Anatomy, EarlyView.
A fossil rostrum fragment of a large teleost fish from the Upper Cretaceous of Northern Italy reveals remarkable anatomical convergences with Cenozoic and Recent billfishes (marlins, swordfishes, and akin). The extinct group Plethodidae independently acquired a long snout, micro‐teeth, and oil‐gland sinuses well before the evolution of true billfishes.

Environmental drivers of scale morphology in a Canary Island lizard across 3700 m of elevation

open access: yesJournal of Zoology, EarlyView.
Gallotia galloti scale traits are driven by climate and human pressures. High dorsal density correlates with hotter, dryer environments and larger scales with higher sun exposure, while ventral scale variation was associated with isothermality and human influences. These changes highlight morphological responses to environmental conditions.

Cosmic ray exposure and gas retention ages of the shocked angrite Northwest Africa 7203: Implications for a collisional history of angrites' parent body

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Angrites and eucrites are among the oldest basaltic rocks in the solar system. However, the shock histories of these meteorite groups differ markedly, as most angrites show little to no evidence of shock metamorphism. While some angrites exhibit weak wavy extinction in olivine, indicative of low‐level shock, only two—Northwest Africa (NWA ...

Visionaries and Crackpots, Maniacs and Saints: Existential Risk and the Politics of Longtermism

open access: yesRatio, EarlyView.
ABSTRACT Despite advancing strong claims about our collective priorities, longtermism has received little attention in debates in political philosophy. I first provide an account of longtermism that highlights the way it departs from established work on intergenerational justice.

(Co‐)Reference All the Way Down: A Unified Theory of (Pro) Nominals in Ordinary English

open access: yesTheoria, EarlyView.
ABSTRACT This essay joins two themes, both arising from Kripke's inspiring ideas in the theory of reference. The first theme concerns reference in general. The second examines the notion of co‐reference and the role it plays in a unified theory of pronouns for natural language.

Shot noise and reconstruction of the acoustic peak

open access: yes, 2010
We study the effect of noise in the density field, such as would arise from a finite number density of tracers, on reconstruction of the acoustic peak within the context of Lagrangian perturbation theory.

Unseasonable seasons: Shifting geographies of weather and migration mobilities

open access: yesTransactions of the Institute of British Geographers, EarlyView.
Abstract The seasons are part of and produced through weather cycles and climate knowledge, yet they are also a distinctive temporal and spatial framing that has been hinted at in aspects of geography and mobility research but is still relatively underexplored. Seasonal concerns underpin not only the weather, but also migration flows, tourism and trade,

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

open access: yesExperimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...
