A Closed‐Loop Human Resource Management Framework for Energy Efficiency: Integrating Predictive Optimization With Behavioral Implementation

open access: yesEnergy Science &Engineering, EarlyView.
The proposed framework operates as a continuous cycle: organizational data streams feed into predictive optimization, which generates energy efficiency targets. These targets are translated into behavioral directives through human resource management mechanisms.

Threshold Asymmetric Conditional Autoregressive Range (TACARR) Model

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT This paper introduces a Threshold Asymmetric Conditional Autoregressive Range (TACARR) model for analyzing the daily price ranges of financial assets. The proposed formulation assumes that the conditional expected range switches between two regimes, representing upward and downward market states, with the disturbance distribution also allowed ...

Large Section of Soft Rock Gob‐Side Entry Retaining Surrounding Rock Control

open access: yesAdvances in Civil Engineering
When cutting roof and pressure relief, the impact of blasting is especially obvious on the integrity of the roof of a large‐section soft‐rock roadway. The reasonable parameters of blasting roof cutting were studied through using Xiaohezui coal mine ‐12110 roadway as the engineering background. The LS‐Dyna simulation results show that: Interval blasting

Disrupting the herd: Recreational boating alters group dispersion within beluga whale herds

open access: yesThe Journal of Wildlife Management, EarlyView.
Recreational boating in beluga habitat remains poorly documented. Using land‐based observations in the Saguenay Fjord (Quebec, Canada), we show that increasing recreational boat numbers are associated with a higher probability of changes in beluga herd dispersion, suggesting behavioral disturbance and the need to integrate recreational boating into ...

‘More Beastliness Than Beauty’: Gendering Pica in Seventeenth‐Century English Medicine and Culture

open access: yesGender &History, EarlyView.
ABSTRACT Today, defined as the ‘persistent eating of non‐nutritive substances’, pica is a lesser‐known eating disorder with a long history. Defined in early modern England as the ‘desire to eat absurd things’, pica was explicitly gendered, associated with pregnant women and pubescent girls.

A Survey of the Archival Audit Literature Une revue de la littérature en matière d'audit fondée sur les données archivales

open access: yesContemporary Accounting Research, EarlyView.
ABSTRACT External audits enhance the credibility of financial statements and are a cornerstone of capital market integrity. However, the growing and complex auditing literature poses challenges for researchers. This survey synthesizes and critically evaluates archival audit research published in top accounting journals from 1995 to 2025, organizing ...
