How Does Trade Policy Uncertainty Affects Innovative Behavior in Export‐Oriented Enterprise: Evidence From Listed Export Companies of Chinese

open access: yesDiscrete Dynamics in Nature and Society, Volume 2025, Issue 1, 2025.
This paper discusses the impact of trade policy uncertainty (TPU) on innovative behavior in export‐oriented enterprises using data of nonfinancial Chinese A‐share listed companies from 2007 to 2021. TPU index is constructed using a tariff measurement method and a text mining method after China’s accession to the WTO.

A Concrete Resistivity Method Based on a Simple Measuring Cell for Onsite Corrosion Monitoring: Study on Concrete Under Varying Conditions

open access: yesStructural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
Concrete resistivity (ρ) is commonly monitored in situ using sensors based on the rebar‐disc (RDM) or four‐electrode (FEM) methods. This study validates, for the first time in reinforced concrete, an innovative corrosion sensor approach (CSA) previously tested only in simulated pore solutions.

Numerical investigations on the influence of the nominal hole clearance on the plate resilience of high strength preloaded bolted joints Numerische Untersuchungen zum Einfluss des Nennlochspiels auf die Plattennachgiebigkeit von hochfest vorgespannten Schraubenverbindungen

open access: yesMaterialwissenschaft und Werkstofftechnik, Volume 55, Issue 12, Page 1687-1706, December 2024.
Zur Erhöhung des Nennlochspiels kommen in geschraubten Verbindungen häufig Langlöcher zum Einsatz. Um dennoch eine reibschlüssige Tragwirkung gewährleisten zu können, muss u. a. ein Hineinziehen der Scheiben in das Langloch vermieden werden. Slotted holes are often used in bolted connections to increase the nominal hole clearance.

Comparison of analytical and numerical methods for estimating notch strains** Vergleich von analytischen und numerischen Verfahren zur Abschätzung von Kerbdehnungen

open access: yesMaterialwissenschaft und Werkstofftechnik, Volume 55, Issue 6, Page 719-732, June 2024.
Applicability of different notch rules for determining elastic‐plastic stresses and strains are evaluated using experimental and numerical data. Amongst the different studied notch rules, Neuber′s rule for mild notches and Sonsino′s averaging method gave best correlation with the experimental data of notched steel and aluminum components and numerical ...

Anordissement, autochtonisation et rétention du personnel extrarégional de l'éducation, de la santé et des services sociaux au sein des communautés innues et naskapie de la Côte‐Nord (Québec)

open access: yesCanadian Geographer / Le géographe canadien, Volume 68, Issue 2, Page 234-246, Summer / été 2024.
Résumé La pénurie de main‐d'œuvre au sein de la fonction publique dans les communautés autochtones du Nord pose un double problème, celui d'engager sur‐le‐champ des professionnel·le·s, souvent des allochtones en provenance du Sud, et de s'assurer que leur intégration outrepasse les fondements du racisme systémique.
