A Newton-Kantorovich Inverse Function Theorem in Quasi-Metric Spaces

The purpose of this work is to investigate root finding problems defined on (quasi-)metric spaces, and ranging in Euclidean spaces. The motivation for this line of inquiry stems from recent models in biology and phylogenetics, where problems of great ...

Continued population recovery and high annual survival rates of White‐rumped Vultures in Nepal

Ibis, EarlyView.
Populations of Gyps vultures in South Asia underwent catastrophic declines caused by unintentional poisoning by the veterinary drug diclofenac. Since the drug was banned in 2006–2010, declines have halted across the region, including in Nepal. The present study updates population trends of G.

Hatching failure and embryo mortality in endangered populations of Eurasian Curlew (Numenius arquata)

Ibis, EarlyView.
Hatching failure represents a significant and growing barrier to reproductive success in threatened birds and yet is often poorly understood. Populations of the Eurasian Curlew Numenius arquata in the United Kingdom and Republic of Ireland have experienced significant declines over recent decades, and low breeding productivity is a major barrier to ...

Debt Aversion: Theory and Measurement

International Economic Review, EarlyView.
ABSTRACT We propose a model of debt aversion and conduct an experiment with real debt and saving contracts to jointly elicit debt aversion and preferences over time, risk, and intertemporal losses. We find that 89% of participants are debt averse, which strongly influences their choices.

The Effect of Listening Strategy Intervention on the Development of Young Learners’ L2 Listening Skills

International Journal of Applied Linguistics, EarlyView.
ABSTRACT The impact of strategy intervention on second language (L2) listening development has been explored in various contexts; however, research on both implicit and explicit listening strategy interventions for young learners remains limited.

Random‐key optimization for 2D irregular packing with reusable area evaluation

International Transactions in Operational Research, EarlyView.
Abstract The diverse constraints of industrial applications lead to variants of two‐dimensional (2D) irregular packing problems that require tailored solution methods. This paper addresses a real‐world industrial challenge by proposing a new problem definition, the maximum reusable contiguous area problem (MRCAP), and a novel metric, the maximum ...
