From routine jobs to algorithmic labor: a digital labor history of Generative AI and shifts in employer hiring demand in China, 2016–2024

This article treats online job advertisements as a digital archive of how firms classify skills, credentials, and tasks, thereby reconstructing the early evolution of employer demand in the context of generative artificial intelligence (GenAI) in China. Drawing on more than 13 mi...

A dynamic explainable AI framework for real-time intrusion detection and automated alert prioritization in security operation centers

Abstract Security Operation Center (SOC) analysts face 50–100 security alerts per hour, leading to cognitive fatigue and delayed incident response. Existing intrusion detection systems (IDS) suffer from high false-positive rates and opaque black-box architectures that erode analy...

Analysis of disturbance dynamo and plasma bubble phenomena over Malaysia during the May 2024 geomagnetic storm

This study presents the first observational report of ionospheric disturbance dynamo (Ddyn) signatures derived from Malaysian magnetometer stations and examines their relationship with equatorial plasma bubble (EPB)-related ionospheric irregularities during the extreme geomagneti...

Robust RSSI indoor localization through federated adversarial training

Wi-Fi RSSI-based indoor localization offers a practical foundation for context-aware services but is challenged by data privacy concerns and susceptibility to adversarial perturbations. This paper presents FedAdvLoc as an application-oriented federated training design that incorp...

Versatile Operational Optimization of Combined Heat and Power Systems Using the Graph Theory

Abstract The operation of combined heat and power (CHP) systems often requires switching between configurations to meet varying demands and operating requirements. This paper presents a hybrid framework for the structural optimization of integrated heat and power systems using P-...

Productivity, institutional environments, and international contract success: asymmetric moderation evidence from Japanese construction firms

International projects are central to construction firms’ growth, yet whether firm productivity predicts international contract success and why productivity advantages translate differently across institutional settings remain underexplored. This study examines how firm productiv...

Influencer marketing and consumer engagement in shaping the relationship between pro-environmental behavior and sustainable consumption

To explore the relationship between pro-environmental behaviour and sustainable consumption and to assess the mediating effects of cognitive, emotional and behavioural engagement, as well as the moderating effect of influencer marketing, within the Stimulus-Organism-Response (S-O...

Gaussian process surrogate modelling and multi-objective optimization for energy-efficient CO2 capture using functionalized oil palm ash

Agricultural waste-derived adsorbents offer a sustainable approach for carbon capture while supporting biomass valorization. However, identifying operating conditions that simultaneously maximize CO 2 adsorption and minimize energy consumption remains challenging because adsorpti...

Eco‐Friendly Nonfluorinated Coating of Omniphobic Membranes With ZnO Nanoparticles Re‐Entrant Structures: Design, Characterization, and Desalination Performance via Membrane Distillation

ABSTRACT Membrane distillation commonly faces challenges such as wetting, fouling, and scaling, which limit its long‐term desalination performance. In this study, an omniphobic membrane was developed via an ecofriendly coating approach, a nonfluorinated omniphobic PVDF hollow fib...

Integrating Service Quality and Technology Acceptance towards Customer Loyalty in Malaysian Banking: A Proposed Conceptual Framework

Purpose: The rapid digital transformation of the banking industry has fundamentally changed the way financial institutions interact with customers. While service quality and technology acceptance have been widely recognized as critical determinants of customer satisfaction and lo...

Wettability and Interfacial Tension in Carbonate Rocks for CO 2 Storage: A Critical Review of Trapping Mechanisms and Governing Factors

ABSTRACT CO 2 geostorage is a promising strategy toward reducing CO 2 emissions in the atmosphere by storing it in deep geological formations. Safe CO 2 storage is primarily contingent upon efficient structural and capillary trapping mechanisms. These trapping mechanisms are stro...

Environmental Regulatory Pressure and Supply Chain Resilience: Evidence from Chinese Listed Manufacturing Firms

Manufacturing firms face tightening environmental requirements while seeking to maintain supply continuity under disruption. This study examines whether environmental regulatory pressure (ER) is associated with supply chain resilience (SCR) and whether informational, relational,...

Stethoscope disinfection practices among doctors: knowledge, attitudes, barriers, and acceptance of UVC technology

Abstract Background Stethoscopes are widely used across multiple patients and can serve as reservoirs of healthcare-associated infections if not disinfected. This study assessed doctors’ knowledge, attitudes and practices regarding stethoscope disinfection, perceived barriers, aw...

Tertiary Students’ Perceptions of an ESL Writing Course Using a Reflective Critical Approach

This study explores tertiary students’ perceptions of the effectiveness of an ESL Academic Writing course that employs a reflective critical approach in its instruction. The course aims to improve students’ academic writing skills by promoting self-awareness, critical thinking, a...

Octupole deformation in quasiparticle states of odd-mass and odd-odd nuclei

Abstract As a follow up of [Phys. Scr. 99 055305 (2024)], where we studied axial octupole shapes in two-quasiparticle states of even-even nuclei, we investigate this type of shapes in odd-mass and odd-odd well-deformed nuclei, using the Skyrme-Hartree-Fock-BCS approach with selfc...

Geopolitical risk and renewable energy consumption: distributional patterns, innovation, and energy-exporter heterogeneity

Purpose This paper aims to examine how the relationship between geopolitical risk and renewable energy consumption varies across the conditional distribution. It also assesses renewable-energy innovation as a partial channel and energy-exporter status as a moderator. Design/metho...

Engineering and characterization of a novel hydrogel-based cancer spheroid system to recapitulate clinical wIRA -hyperthermia treatments

Background Water-filtered infrared-A (wIRA) mild hyperthermia (mHT) combined with radiotherapy can effectively treat superficial tumors. While in vitro models are essential for mechanistic studies, existing approaches mostly rely on monolayer cultures and non-clinical heating. We...

A conceptual framework for developing a nature loving education teaching module to foster spirituality in young children

Early childhood education is increasingly expected to support children’s holistic development, including emotional, moral and spiritual dimensions. In Malaysia, national preschool curricula emphasise values and character education; however, spirituality in classroom practice ofte...

Sustainable mineral processing risk analysis based initial settling rates prediction using enhanced machine learning models

Abstract The primary contamination concern of mineral processing tailings (MPT) is the leaching of hazardous substances into the environment. The literature indicates that MPT requires effective flocculation and polymer-assisted dewatering to ensure its disposal does not cause en...

Epoxidation of Waste Palm Cooking Applied With Hybrid Zeolite Catalyst Derived From Natural Clinoptilolite/Synthetic ZSM ‐5
