Bias Correction of ERA5 Temperature Across Five Topoclimatic Clusters: A Comparative Evaluation of Four Methods

International Journal of Climatology, EarlyView.
ERA5 near‐surface temperature over South America exhibits systematic cold biases in daily maximum temperature and warm biases in daily minimum temperature. To address the continent's strong climatic and topographic heterogeneity, South America was partitioned into five topoclimatic clusters, and four bias‐correction approaches were evaluated. The Multi‐

Multi‐Timescale Drought Evolution in Greece (1960–2022) From Station‐Based SPI and SPEI

International Journal of Climatology, EarlyView.
Using homogenized data from 67 HNMS stations in Greece (1960–2022), we calculated SPI and SPEI at 1–12‐month scales to characterize meteorological to hydrological drought. We quantified the network‐based spatial extent of drought, compared SPI and SPEI drought signals, and tested changes with autocorrelation‐robust Mann–Kendall trends and Pettitt ...

Agent‐Related Perceptions of Automated Versus Human Agents and the Role of Task‐Related Risk: A Meta‐Analysis

Psychology &Marketing, EarlyView.
ABSTRACT Firms often seek to replace human agents (HAs) with automated agents (AAs) for customer service, but customers still tend to react more negatively to AAs than to HAs. This meta‐analysis examines agent‐related perceptions (i.e., humanlikeness, warmth, and competence), which represent the key upstream customer reactions shaping downstream ...

Approximating Airports and Railways.

, 2018
In this paper we consider the airport and railway problem (AR), which combines capacitated facility location with network design, both in the general metric and the two-dimensional Euclidean space. An instance of the airport and railway problem consists of a set of points in the corresponding metric, together with a non-negative weight for each point ...
