Modelling intumescent coatings for the fire protection of structural systems: a review
Authors: Lucherini Andrea , de Silva Donatella 
Published: February 2024

PurposeIntumescent coatings are nowadays a dominant passive system used to protect structural materials in case of fire. Due to their reactive swelling behaviour, intumescent coatings are particularly complex materials to be modelled and predicted, which can be extremely useful especially for performance-based fire safety designs. In addition, many parameters influence their performance, and this challenges the definition and quantification of their material properties. Several approaches and models of various complexities are proposed in the literature, and they are reviewed and analysed in a critical literature review.Design/methodology/approachAnalytical, finite-difference and finite-element methods for modelling intumescent coatings are compared, followed by the definition and quantification of the main physical, thermal, and optical properties of intumescent coatings: swelled thickness, thermal conductivity and resistance, density, specific heat capacity, and emissivity/absorptivity.FindingsThe study highlights the scarce consideration of key influencing factors on the material properties, and the tendency to simplify the problem into effective thermo-physical properties, such as effective thermal conductivity. As a conclusion, the literature review underlines the lack of homogenisation of modelling approaches and material properties, as well as the need for a universal modelling method that can generally simulate the performance of intumescent coatings, combine the large amount of published experimental data, and reliably produce fire-safe performance-based designs.Research limitations/implicationsDue to their limited applicability, high complexity and little comparability, the presented literature review does not focus on analysing and comparing different multi-component models, constituted of many model-specific input parameters. On the contrary, the presented literature review compares various approaches, models and thermo-physical properties which primarily focusses on solving the heat transfer problem through swelling intumescent systems.Originality/valueThe presented literature review analyses and discusses the various modelling approaches to describe and predict the behaviour of swelling intumescent coatings as fire protection for structural materials. Due to the vast variety of available commercial products and potential testing conditions, these data are rarely compared and combined to achieve an overall understanding on the response of intumescent coatings as fire protection measure. The study highlights the lack of information and homogenisation of various modelling approaches, and it underlines the research needs about several aspects related to the intumescent coating behaviour modelling, also providing some useful suggestions for future studies.

Published: February 2024

PurposeTargeting the common functions of the Zhejiang Library website, elderly individuals were invited to complete six experimental tasks on the improved website interfaces, and subjective data (PAD emotion scale and usability evaluation) and objective data (eye movement data) were recorded to verify the effects of graphic layout and navigation position on the information-seeking experience of elderly individuals.Design/methodology/approachThis study analyzes the effect of the graphic layout and navigation position of the Zhejiang Library’s website interface on the emotional state, perceived usability and information-seeking time of elderly individuals, with the aim of providing guidance and suggestions for the elderly-oriented reform of the public library website.FindingsThe experimental results show that the graphic layout has a significant effect on the emotional state and perceived usability of elderly individuals, and the navigation position has a significant effect on the information-seeking time; the interaction between graphic layout and navigation position exerts a significant effect on the information-seeking time of elderly individuals. The eye movement data show that elderly individuals have a better information-seeking experience when the top navigation bar and image-text matched arrangement are used for the interface layout.Originality/valueThis study adopts a new approach combining subjective data and eye movement data to evaluate the effect of the public library website’s interface layout on the information-seeking experience for older people. The findings can provide a theoretical basis and methodological support for the elderly-oriented reform of public library websites. They can also provide scientific design suggestions for age-friendly interface layouts of other Internet products and service applications.

PurposeUnderstanding employees’ multi-dimensional motivations is at the core of realizing the potential of a well-designed human resource (HR) system. This study aims to investigate whether the effects of HR practices on employee motivations, and their performance would be dependent on the service orientation of HR department.Design/methodology/approachThe authors collected data in two surveys: a pilot survey and a main survey with a two-wave design. The pilot survey with 93 respondents was to verify the newly developed HR service orientation scale. In the main survey, a total of 276 supervisor-subordinate pairs from 48 companies were valid for analysis.FindingsThe authors find support for their hypothesis that promotion-oriented motivation mediates the relationship between discretionary HR practices and employee outcomes [in-role performance and organizational citizenship behavior (OCB)]. Furthermore, the indirect effect of discretionary HR practices on employee outcomes is stronger when the HR service orientation is higher. Transactional HR practices, however, are not evidenced to relate to employee prevention-focused motivation and outcomes.Practical implicationsThe findings illustrate a comprehensive process of HR practices on employees’ multi-dimensional motivations. High service skills of HR professionals in handling internal employees’ needs could amplify employees’ promotion-focused motives, which in turn increase their in-role performance and OCB.Originality/valueIn sum, the authors' study contributes to both human resource management (HRM) and employee motivation literature by demonstrating the different impacts of discretionary and transactional HR practices on employees’ motivations. In addition, by revealing HR service orientation as an important contingency factor, the authors shed greater light on when and how HR practices can motivate employees.

Purpose This study aims to investigate the relationships between the perceived neighborhood walkable environment (PNWE), neighborhood interaction (NI) and residents’ mental health, with a focus on examining differences among residents of different age groups.Design/methodology/approach Using an electronic survey questionnaire, data on PNWE, NI and mental health were collected from 1,159 residents across 205 communities in Shanghai, China. Our study utilized a structural equation modeling (SEM), employing the maximum likelihood estimation method. The structural equation model was fitted using the MPLUS software.Findings The mental health of young and middle-aged adults is generally poor, and they are at higher risk of depression than children and older adults. The effects of PNWE and NI on the mental health of residents varied among different age groups. As residents get older, their mental health is more affected by the PNWE. In addition, the influence of the PNWE on children and older adults’ mental health is direct and not mediated by NI. For young and middle-aged adults, the influence of the PNWE on their mental health needs to be mediated by NI.Originality/value This study marks the first examination of the relationship between PNWE, NI and mental health among different age groups of residents in China. The findings of this research can assist policymakers in gaining a deeper understanding of the underlying mechanisms by which PNWE affects mental health. Furthermore, it can contribute to the development of more targeted walkable environment designs aimed at enhancing mental health among various age groups.

Published: February 2024

PurposeThis study investigates the impact of social media marketing activities on customer purchase intention in the Malaysian property market.Design/methodology/approachThe study utilises a survey research approach to collect data from 331 respondents using a questionnaire.FindingsThe findings of the study reveal that entertainment, interaction, customisation and word-of-mouth variables had a significant and positive impact on customer purchase intention in the Malaysian property market. However, the study demonstrates a positive but insignificant impact of trendiness on customer purchase intention.Research limitations/implicationsFirst, the study relies on a sample of 331 respondents in Malaysia, which may limit the generalizability of the findings to a broader population. Hence, future research could aim for a more extensive and diverse sample to enhance the validity of the results. Second, while the study identified significant relationships, the measurement of variables, in particular “trendiness,” could be refined for better accuracy. The future study may consider including a more precise measurement to provide comprehensive insights.Practical implicationsThe results suggest that marketers should focus on creating engaging and interactive content, providing personalised experiences and leveraging word-of-mouth recommendations to enhance customer purchase intention. The overall findings highlight the importance of social media marketing activities in the property market and their potential to drive customer purchase intention.Social implicationsThe study contributes to the existing literature by shedding light on the role of social media marketing activities in influencing customer purchase intention in the Malaysian property market.Originality/valueTo the best of the authors’ knowledge, there is no similar studies have been conducted in this area of research.

Further, this study is the first one to examine different venues from the perspective of batting strike rate in men’s Twenty20 international matches.
The Importance of Human Rights for Management and Organization Studies
Authors: Schrempf‐Stirling Judith , Van Buren Harry J. 
Published: February 2024

AbstractBusiness and human rights (BHR) scholarship examines the role of business in human rights violations as well as business responsibilities to respect human rights and to provide remedy where needed. BHR scholarship has been thriving over the last several decades, but it is at a turning point that begs for increased cross‐disciplinary exchange. We argue that dealing systematically and explicitly with a human rights perspective in management and organization studies provides BHR scholarship with a new impetus as well as with alternative perspectives on how to understand and further advance human rights obligations on businesses. We advance two BHR conceptualizations that will provide guidance for integrating human rights in management with organization studies research and thereby enlarge the cross‐disciplinary conversation on BHR: BHR as Global Governance and BHR as Sensemaking. This paper expands existing management and organization studies constructs, invites management and organization studies scholars to provide their insights into this important research domain, and discusses the implications of human rights for the firm.

Published: February 2024

AbstractAging is a complex process influenced by genetic, epigenetic, and environmental factors that lead to tissue deterioration and frailty. Epigenetic mechanisms, such as DNA methylation, play a significant role in gene expression regulation and aging. This study presents a new age estimation model developed for the Turkish population using blood samples. Eight CpG sites in loci TOM1L1, ELOVL2, ASPA, FHL2, C1orf132, CCDC102B, cg07082267, and RASSF5 were selected based on their correlation with age. Methylation patterns of these sites were analyzed in blood samples from 100 volunteers, grouped into age categories (20–35, 36–55, and ≥56). Sensitivity analysis indicated a reliable performance with DNA inputs ≥1 ng. Statistical modeling, utilizing Multiple Linear Regression, underscores the reliability of the primary 6‐CpG model, excluding cg07082267 and TOM1L1. This model demonstrates strong correlations with chronological age (r = 0.941) and explains 88% of the age variance with low error rates (MAE = 4.07, RMSE = 5.73 years). Validation procedures, including a training‐test split and fivefold cross‐validation, consistently confirm the model's accuracy and consistency. The study indicates minimal variation in error scores across age cohorts and no significant gender differences. The developed model showed strong predictive accuracy, with the ability to estimate age within certain prediction intervals. This study contributes to the age prediction by using DNA methylation patterns, which can have disparate applications, including forensic and clinical assessments.

AbstractObjectiveThe prevalence TFCC injuries has increased over time. However, there remains a lack of understanding of its natural history. Along with the paucity of evidence on treatment options, there is lack of consensus on how best to manage them. This is a retrospective study with subgroup cohort analysis, examining variables and management options associated with patient‐reported disability and pain.MethodsPatients from a metropolitan health network who have been referred for Magnetic Resonance Imaging (MRI) of the wrist between 2010 and 2019 and identified to have TFCC injury, were followed up to determine patient‐reported outcomes. Disability of arm shoulder and hand scores (DASH) and visual assessment pain scale (VAS) were used to measure disability and pain respectively. An ‘excellent’ DASH and VAS scores were defined as ≤10 and ≤2, respectively.ResultsOne hundred and twenty‐four patients met the inclusion criteria and consented to participate in this study. There were 53 patients with excellent DASH score, 95 excellent VAS score and 51 excellent outcomes at mean follow‐up of 75.5 months (Range: 5–402.8 months). Concomitant pathology and surgical management were less likely to have excellent DASH and VAS scores, while traumatic aetiology and smoking were less likely to have excellent VAS score. Age was not predictive of excellent DASH or VAS score.ConclusionsSurgical management of TFCC injuries were associated with worse outcomes than if they were left alone. Smoking cessation is a patient‐modifiable risk factor that may help improve outcomes.

Published: February 2024

AimsBoth effective analgesia and early breastfeeding play an important role in maternal and neonatal well‐being after Caesarean delivery. We studied controlled‐release oxycodone tablet treatment for postoperative pain management and determined the excretion of oxycodone into breast milk.MethodsControlled‐release oxycodone/naloxone 10/5‐mg tablets (n = 21) or controlled‐release oxycodone 10‐mg tablets (n = 22) were administered to mothers twice a day for the first 3 days after elective Caesarean delivery as a part of multimodal analgesia. Maternal plasma and breast milk samples were collected daily. Oxycodone, noroxycodone, oxymorphone and noroxymorphone concentrations were analysed with ultra‐performance liquid chromatography‐mass spectrometry. Maternal pain intensity was recorded with an 11‐point Numeric Rating Scale (0‐10). Neonatal oxycodone exposure was estimated by simulating five different exposure scenarios, including the highest possible exposure through breast milk.ResultsThe mean oxycodone and noroxycodone milk‐to‐maternal plasma ratios were 3.2 and 3.0, respectively. A strong correlation was found between plasma and breast milk oxycodone (R2 = 0.87) and noroxycodone concentrations (R2 = 0.91). In the simulated highest neonatal exposure scenario, the neonate's maximum plasma concentration was estimated to be 5.4 ng/mL and the estimated weight‐adjusted infant oxycodone dose was less than 10% of the maternal dose. Pain intensities were similarly low between the two treatment groups.ConclusionsThe oxycodone dose received from colostrum and breast milk during the first three postoperative days after Caesarean delivery is assumed safe for healthy, term neonates, but in extreme cases it is possible for the neonate to receive a dose through breast milk that may elicit opioid effects.

AbstractMethadone (R,S‐methadone) can prolong the QT interval. R‐methadone inhibits cardiac potassium channel function less than S‐methadone. We tested if switching from methadone to R‐methadone would reduce corrected QT (QTc) intervals in methadone maintenance treatment (MMT) patients. Nine patients, with automatically read QTc intervals ≥450 ms, were required to detect a 20 ms (clinically relevant) reduction in QTc intervals with 15 ms standard deviation (SD) and 90% power. Nine stabilized MMT patients, using median (range) 70 (40–120) mg methadone, were included. Data (ECG recordings, serum samples, and withdrawal symptoms) were collected both before drug intake (Cmin) and at 3 h after drug intake (Cmax), and were collected on the day before the switch from methadone to equipotent R‐methadone dose and at 14 and 28 days after the switch. A cardiologist calculated QTc intervals retrospectively. Serum electrolytes and methadone concentrations were measured. Mean QTc intervals at Cmin were 472 ms and 422 ms on methadone (automatically and manually read) and 414 ms on R‐methadone (manually read). Mean (SD) change in QTc intervals was −8 (10) ms (p = 0.047) at Cmin but non‐significant at Cmax. R‐methadone showed a concentration‐dependent relationship with QTc intervals. Switching to R‐methadone reduced QTc intervals, but far less than the 20 ms considered clinically relevant.
