Toward Conceptual Clarity in Sustainable Human Resource Management: A Systematic Review of Definitions, Operationalisations and Outcomes

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Sustainable Human Resource Management (SustHRM) has attracted growing scholarly attention, yet substantial variation remains in how the construct is defined and empirically examined. This systematic literature review assesses the conceptual clarity of SustHRM by synthesizing 148 peer‐reviewed articles.

Fault diagnosis of reciprocating compressor using Teager-Kaiser energy operator and envelope spectral feature extraction

open access: yesAdvances in Mechanical Engineering
This paper proposed and implemented the Teager-Kaiser energy operator (TKEO) and envelope spectral analysis techniques for the fault detection of discharge valves of a reciprocating compressor. Based on the extraction of fault features, the instantaneous

Dynamic cracking properties and generating conditions of coal under rapid gas release

open access: yesDeep Underground Science and Engineering, EarlyView.
Gas release tests revealed that crack initiation and propagation are jointly controlled by initial crack length, residual strength, and gas release velocity. A new outburst risk coefficient was thus developed from a fracture mechanics perspective, offering a novel predictive approach.

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

open access: yesDeep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Reciprocal Learning

open access: yesAdvances in Neural Information Processing Systems 37
We demonstrate that a wide array of machine learning algorithms are specific instances of one single paradigm: reciprocal learning. These instances range from active learning over multi-armed bandits to self-training. We show that all these algorithms do not only learn parameters from data but also vice versa: They iteratively alter training data in a ...

Mechanism of “seesaw‐type” rock burst in coal seam mining beneath mountainous areas

open access: yesDeep Underground Science and Engineering, EarlyView.
This study reveals the mechanism of “seesaw‐type” rock bursts during coal mining beneath mountainous areas. The advancing working face induces nonuniform fracturing of the overburden. The detached mountain mass then undergoes a seesaw‐type rotational movement around a shifting pivot, driving the primary fracture through a characteristic “open‐close ...

Incidence and localization of reciprocating endodontic instrument separation: a systematic review and meta-analysis

open access: yesAnnali di Stomatologia
Despite the advantages provided by the motion, single-file reciprocating instruments may also be subjected to intracanal separation. Understanding the incidence and common anatomical locations of separation is critical for risk assessment and clinical ...

Analysis of wear mechanism in TPU-steel contact pair by means of long stroke tribometer tests [PDF]

open access: yes, 2012
A complete wear characterisation of a thermoplastic polyurethane (TPU) sliding against steel is presented. Wear tests were performed using a long stroke tribometer under sliding reciprocating movement and dry conditions.
