What comes first? The chicken-egg relationship between integrated thinking and reporting
No full textThis study provides new empirical evidence on the relationship between integrated thinking (IT) and integrated reporting (IR). It contributes to the chicken–egg debate between IT and IR by answering the question ‘what comes first?’ and examines the determinants of IT and IR for a sample of European listed companies. The findings from both the empirical analysis and interviews with IR preparers show that IT leads to IR, and vice versa, thus creating a virtuous circle where the decision to publish an integrated report favours an inclusive decision-making process, as well as embracing the IT journey favours the adoption of IR. These results could drive companies’ internal choices and policymakers’ initiatives aimed at progressing an integrated organisational culture by identifying the differential drivers of IR and IT and suggest that companies’ journey towards integration can start either from the integrated report (IR develops IT) or from developing an IT culture that creates a fertile background for IR (IT leads to IR)
Clinical and cost-effectiveness of a home-based health promotion intervention for older people with mild frailty in England : a multicentre, parallel-group, randomised controlled trial
Full text linkHealth promotion for people with mild frailty has the potential to improve health outcomes, but such services are scarce in practice. this study developed a personalised, home-based, behaviour change, health promotion intervention (HomeHealth) and assessed its clinical effectiveness and cost-effectiveness in maintaining independent functioning in activities of daily living in older adults with mild frailty. HomeHealth is a multidomain health promotion intervention delivered by the voluntary sector at home in six sessions over 6 months
Moderate-to-vigorous and light-intensity aerobic exercise yield similar effects on food reward, appetitive responses, and energy intake in physically inactive adults
Full text linkThis study examines the effect of acute aerobic exercise at moderate-to-vigorous and light intensity on food reward, appetite sensation, and energy intake (EI) in physically inactive adults. Twenty inactive, healthy adults (mean age: 21 ± 3 years) completed two trials (i.e. moderate-to-vigorous and light-intensity exercise) in a randomised, crossover design. Participants performed a 40-min cycling bout at either 50% or 20% peak power output in a counterbalanced order. Before and after exercise bouts, liking and wanting for fat and sweet/savoury categories of food were assessed by the Leeds Food Preference Questionnaire, along with subjective ratings of appetite and state food cravings. EI was evaluated by ad libitum meals following exercise bouts
Calculation of interphase elastic properties of esterified cellulose nanocrystal/epoxy bio-nanocomposites using analytical and finite element methods
Full text linkIn this study, analytical models and numerical finite element analysis (FEA) were used to accurately determine the interphase properties and elastic modulus of both untreated and esterified cellulose nanocrystals (CNC)/epoxy bio-nanocomposites. This was achieved by incorporating an interphase region around the CNC particles, with properties that vary between those of the nanofiller and the matrix. Experimental techniques for measuring interphase properties, such as atomic force microscopy and nanoindentation, are useful but sensitive to sample preparation and limited to certain materials, which makes modelling a valuable alternative. Random 2D and 3D representative volume elements (RVEs) were generated using Digimat-FE and imported into ANSYS to determine the behaviour of nanocomposite under load. The elastic moduli values from analytical and FEA models, which included the interphase region, fell within the range of experimental variation. The results showed that the modulus increased with CNC loading from 2.5 wt% to 5 wt% and that nanofiller treatment enhanced the modulus and increased the interphase thickness. For excessive esterification, there was a weakening effect on the composite that the analytical models failed to accurately predict. ANSYS response surface optimization was used to determine the optimal geometries and material properties for the FEA model, leading to accurate behaviour. Latin hypercube sampling (LHS) was used to explore the design space, and the optimal geometry was identified with a 6 nm interphase thickness, an aspect ratio of 10, a CNC modulus of 0.66 MPa, and an interphase modulus of 1.28 GPa. The 2D FEA RVE models struck a balance between accuracy and computational costs for treated nanoparticles
Tensile and flexural behaviour of synthetic and hybrid natural fiber composites for lightweight applications
No full textThe growing demand for lightweight and sustainable materials has driven research into hybrid composites that combine synthetic and natural fibers. This study aims to investigate the tensile and flexural behavior of carbon fiber (CF) and glass fiber (GF) composites, alongside hybrid composites incorporating flax and hemp fibers. The composites were fabricated using the vacuum bagging technique, ensuring uniform fiber distribution and optimized mechanical properties. Experimental results revealed that CF composites exhibited the highest ultimate tensile strength (~550 MPa), with failure dominated by matrix cracking and fiber breakage due to their inherent brittleness. GF composites, while having a lower tensile strength (~450 MPa), demonstrated greater ductility, attributed to fiber pull-out and matrix cracking. Hybrid composites (H1), combining CF and GF, showed intermediate tensile strength (~500 MPa), reflecting mixed failure modes. In contrast, natural fiber composites (FH and H2) displayed significantly lower strengths (~150–200 MPa) due to weaker fiber-matrix interactions and moisture sensitivity. Despite their lower strength, hybrid composites provided a balance between mechanical performance and sustainability, making them a promising alternative for lightweight structural applications in automotive, aerospace, and eco-friendly engineering. These findings highlight the potential of hybrid composites in reducing environmental impact while maintaining structural integrity, offering a viable solution for next-generation sustainable materials

No full textExploring the role of job satisfaction in enhancing logistics performance in the era of industry 5.0
No full textThis paper presents an empirical study exploring how job satisfaction influences logistics performance in Industry 5.0, focusing on the key logistics capabilities of innovation and customer responsiveness. Although the logistics business is evolving rapidly, emerging technologies have been applied in the logistics business, human jobs cannot be completely replaced. Based on the High-Performance Work Systems theory and resource-based view, it is crucial to exploit internal resources and capabilities to achieve sustainable competitive advantage and performance. The empirical data were collected in the Australian courier sector, and a total of 161 valid responses were used in the data analysis. We conducted partial least squares structural equation modelling to validate models and test the research hypotheses. The findings suggest a significant impact of job satisfaction on logistics performance, with logistics capabilities playing a mediating role in the relationship between job satisfaction and logistics performance
Factors associated with retinal vessel traits in the Canadian longitudinal study on aging
Full text linkThis study aims to determine the factors cross-sectionally and longitudinally associated with retinal vessel diameter, total area, and tortuosity in the Canadian Longitudinal Study on Aging (CLSA). Current smoking was strongly associated with wider arteriolar and venular diameters and their widening over 3 years (P < 0.05). Current smoking was also associated with a larger arteriolar and venular area and a 3-year increase in venular area (P < 0.05). Obesity was positively associated with venular diameter, total venular area, 3-year change in total venular area, and venular tortuosity (P < 0.05). Diastolic blood pressure was negatively associated with both arteriolar and venular diameter, area, and tortuosity, both cross-sectionally and longitudinally (P < 0.05). Diabetes was associated with wider arteriolar diameters cross-sectionally, and type 1 diabetes was associated with 3-year widening of arteriolar diameters (P < 0.05)
