Inclusive leadership, symbolic capital and employee retention: social recognition beyond managerial authority

Purpose Labour-constrained workplaces face growing challenges in sustaining employment relationships amid workforce mobility and labour shortages. While inclusive leadership is associated with positive employee outcomes, less is known about how inclusive practices acquire influen...

Adolescent pregnancy and adverse maternal and perinatal outcomes: a systematic review and meta-analysis

Adolescent pregnancy remains a major global public health concern, yet evidence on its association with a broad range of maternal and perinatal outcomes remains fragmented. We conducted a systematic review and meta-analysis of observational studies comparing adolescents (13–19 ye...

Steel Inter-Modular Connections for Resilient and Sustainable Modular Buildings: A Structured Comparative Review and Design Framework

Inter-modular connections (IMCs) govern the structural performance, safety, seismic resilience, and reusability of steel modular buildings, yet the existing literature on advanced IMC systems remains fragmented and connection-specific. This paper presents a comparative review of...

Polylactic acid/cellulose nanocrystals/polyethylene glycol-based shape memory composite for a 4D printed thermoresponsive gripper system

This work introduces a novel thermo-responsive 4D printable gripper system via polylactic acid (PLA), cellulose nanocrystals (CNC), and polyethylene glycol (PEG)-based shape memory composite. PEG, serving as a biocompatible plasticizer, and CNC, acting as a biodegradable reinforc...

Synthesis of morphologically different SnHPO 4 using a refluxing method

This work presents a simple and efficient reflux method for the synthesis of Tin(II) hydrogen phosphate (SnHPO4). This method is faster and requires less instrumentation. The reported methods use highly hygroscopic SnCl2 as the starting material, whereas the current method uses m...

Power-Efficient Ultra-Reliable Communication in Rayleigh–Rayleigh Fading Environment Using ARQ-I and CC-HARQ

We propose optimal power allocation for a transmitter that operates with either the ARQ-I or CC-HARQ protocol in an interference-limited environment where both the desired and interfering signals experience Rayleigh fading, forming an analytically tractable non-line-of-sight scen...

Knowledge, use and perceptions of AI-based chatbots among medical undergraduates in Sri Lanka: a cross-sectional study

AI-based chatbots are increasingly used in medical education, but evidence from Sri Lanka is limited. This study assessed medical undergraduates’ knowledge, use, perceptions, barriers, and expectations regarding these tools. A cross-sectional online survey included 400 pre-clinic...

The impact and evolution of environmental/occupational, behavioural, and metabolic risk factors on CVD burdens in the Asia–Pacific region from 1990 to 2023: a secondary analysis of the Global Burden of Disease Study 2023

Background Understanding epidemiological trends of the cardiovascular risk factors is integral in designing effective countermeasures in tackling cardiovascular diseases (CVD) in the Asia–Pacific. The study aims to examine the cardiovascular risk factor burden in the Asia–Pacific...

Trends in the PromisingFunctional Pigment, Phycocyanobilin:Preparation, Health Benefits, and Utilization

Abstract Phycocyanobilin (PCB) is a linear tetrapyrrole chromophore covalently bound to phycocyanin that is widely distributed in cyanobacteria and certain microalgae. PCB has attracted increasing attention, because of its well-defined structure, excellent biocompatibility, and d...

Glycemic changes during first 48 h postpartum in mothers with gestational diabetes mellitus and non—diabetic mothers – a comparative study

Gestational diabetes mellitus (GDM) is a common metabolic disorder in pregnancy and is associated with an increased risk of maternal complications and future development of type 2 diabetes mellitus. While glycemia is expected to normalize after delivery due to loss of placental h...

To complain or not to complain: Navigating intrusive service experiences of solo female travelers

Recent solo travel statistics show a continual increase in solo female traveller (SFT) numbers, creating new market opportunities for destination management organisations (DMOs). While SFTs are a lucrative market segment, their experience and by implication, their spending, at se...
