Combustion Properties of Timber in Historic Structures: Case Study of the São Pedro de Alcântara Chapel Fire

Fire and Materials, EarlyView.
ABSTRACT Timber plays a fundamental role in the fire performance of historic building components, where ageing and environmental exposure can markedly influence its physical and chemical properties. This study presents an experimental investigation of the fire behaviour of Ocotea sp.

Temporal Robustness in Cross‐Country Gross Domestic Product Forecasting: Evidence From Classical, Regime‐Switching, and Ensemble Models

Journal of Forecasting, EarlyView.
ABSTRACT This study evaluates whether the relative performance of gross domestic product forecasting models is temporally robust across economies and changing macroeconomic conditions. Using annual real gross domestic product data from the World Bank for 177 separately reported economies and territories, we conduct a common‐vintage pseudo‐out‐of‐sample

Harnessing the Potential of LLMs in Hospital Management: Insights Into Medical Data Inquiry

The International Journal of Health Planning and Management, EarlyView.
ABSTRACT Background Considering the rapid expansion of hospital operations and the increasing digitisation of medical data, there is a pressing need for efficient and intelligent methods to process and analyse large‐scale medical data. Methods We integrated the QLoRA algorithm with ChatGLM2‐6b, Llama2‐7b, and Llama2‐13b models, fine‐tuning them on a ...

The Impact of Monetary Policy Shocks on Stock Price Crash Risk

International Journal of Finance &Economics, EarlyView.
ABSTRACT This study examines the impact of monetary policy shocks (MPS) on future stock price crash risk (SPCR), using a sample of US firms from 1995 to 2019. We find that expansionary MPS significantly reduce the likelihood of SPCR, while contractionary MPS show no statistically significant effect on SPCR. These results remain robust after controlling

Two Two‐Tier Stochastic Frontier Replications

Journal of Applied Econometrics, EarlyView.
ABSTRACT We replicate the two foundational studies which proposed the two‐tier stochastic frontier model, first in the cross‐sectional setting and then for the fixed effects panel data model. We explore matters of software then and now, different mathematical formulations of the likelihood, and alternative current software tools.
