Published: November 2023

AbstractDavana (Artemisia pallens) is a valuable aromatic herb within the Asteraceae family, highly prized for its essential oil (EO) produced in the aerial parts. However, the root volatiles and their specific composition, and genes responsible for root volatiles have remained unexplored until now. Here, we show thatA. pallensroots possess distinct oil bodies and yields ∼0.05% of EO, which is primarily composed of sesquiterpenes β-elemene, neryl isovalerate, β-selinene, and α-selinene, and trace amounts of monoterpenes β-myrcene, D-limonene. This shows that, besides aerial parts, roots of davana can also be a source of unique EO. Moreover, we functionally characterized a terpene synthase (ApTPS1) that exhibited highin silicoexpression in the root transcriptome. The recombinant ApTPS1 showed the formation of β-elemene and germacrene A withE,E-farnesyl diphosphate (FPP) as a substrate. Further, detailed analysis of assay products revealed that β-elemene was the thermal rearrangement product of germacrene A. Furthermore, the functional expression of ApTPS1 inSaccharomyces cerevisiaeconfirmed thein vivoβ-elemene/germacrene A synthase activity of ApTPS1. At the transcript level,ApTPS1displayed predominant expression in root, with significantly lower level of expression in other tissues. This expression pattern ofApTPS1positively correlated with the tissue-specific accumulation level of β-elemene. Overall, these findings provide fundamental insights into the EO profile of davana roots, and the contribution of ApTPS1 in the formation of a major root volatile.Main conclusionThe study demonstrated thatArtemisia pallensroots can be a source of terpene-rich essential oil and root-specific ApTPS1 forms germacrene-A contributing to major root volatiles.

Purpose
The anticorrosion coatings used in marine and atmospheric environment are subjected to many environmental factors. And the aging failure has been puzzling researchers. The purpose of this study is to find the correlation between the initial aging of epoxy coatings and the typical marine atmospheric environmental factors.

Design/methodology/approach
The epoxy coatings were subjected to a one-year exposure in three typical marine atmospheres. Meanwhile, principal component analysis, linear regression and Spearman and gray correlation analysis were applied to quantify the environmental characteristics and establish correlations with the coating aging.

Findings
The results indicate that the coating will undergo macroscopic fading and chalking upon exposure to the marine atmosphere, while microscopic examination reveals holes, cracks and partial peeling. The adhesion performance and electrochemical properties of the coating deteriorated with prolonged exposure, coating aging mainly occurs with the generation of O-H bonds and the breakage of molecular chains such as C-N and C-O-C. The coating was most deeply aged after exposure to the Xisha, followed by Zhoushan and finally Qingdao. Environmental factors affect the photooxidative aging and hydrolytic degradation processes of coatings and thus coating aging. To further demonstrate the correlation between environmental factors and coating aging, principal component analysis was used. The correlation model between environmental factors and coating aging was subsequently obtained. The correlation model between the rate of coating adhesion loss (E) and the comprehensive evaluation parameter of environmental factors (Z) is expressed as E = 0.142 + 0.028Z. Meanwhile, the Spearman correlation analysis and gray correlation method were used to investigate the impact of each environmental factor on coating aging. Solar irradiation, relative humidity and wetting time have the highest correlation with coating aging, which are all above 0.8 and have the greatest influence on coating aging; wind speed and temperature have the smallest correlation with coating aging, which are about 0.6 and have the least influence on coating aging.

Originality/value
This paper establishes a correlation between typical marine environmental factors and coating aging performance, which is crucial for predicting the service life of other coatings in diverse environments.
Impact of circular economy practices on supply chain capability, flexibility and sustainable supply chain performance
Authors: Malhotra Gunjan 
Published: November 2023

PurposeThis paper analyses the effect of circular economy practices on sustainable supply chain performance. The study explores the impact of mediating variables such as supply chain flexibility and capabilities and the moderating role of supply chain integration in the relationship between circular economy practices and sustainable supply chain performance in Indian manufacturing firms. The study builds on the stimulus-organism-response (S-O-R) model to conceptualise circular economy practices that influence supply chain capabilities, integration and flexibility, impacting sustainable supply chain performance.Design/methodology/approachThis study adopted an online survey questionnaire distributed to managers of Indian manufacturing firms adopting circular economy practices. The data were analysed using SPSS Amos 25 and PROCESS macros.FindingsThe results suggest a positive impact of circular economy practices on sustainable supply chain performance in manufacturing firms. In addition, a supply chain manager's relationship with retailers is improved in the presence of supply chain capabilities and flexibility. Supply chain integration further strengthens this relationship as a moderating variable.Originality/valueBy examining the literature on circular economy practices and sustainable supply chain management, this study contributes to bridging the gap between supply chain capabilities, integration and flexibility using the S-O-R model. This study is possibly among the first to explore and provide empirical evidence on how circular economy practices in manufacturing firms can impact supply chain managers' experiences and thus help to improve environmental well-being. Both academics and business professionals might find these contributions interesting.
The impact of financial assets’ classification according to IFRS 9 on firm value: the case of MENA region’s banks
Authors: Ben Ltaief Khouloud , Moalla Hanen 
Published: November 2023

Purpose
The purpose of this study is twofold. On the one hand, it studies the impact of IFRS 9 adoption on the firm value; and on the other hand, it investigates the impact of the classification of financial assets on the firm value.

Design/methodology/approach
The study covers a sample of 55 listed banks in the Middle Eastern and North African (MENA) region. Data is collected for three years (2017–2019).

Findings
The findings show that banks’ value is not impacted by IFRS 9 adoption but by financial assets’ classification. Firm value is positively affected by fair value through other comprehensive income assets, while it is negatively affected by amortized cost and fair value through profit or loss assets. The results of the additional analysis show consistent outcomes.

Practical implications
This research reveals important managerial implications. Priority should be given to the financial assets’ classification strategy following the adoption of IFRS 9 to boost the market valuation of banks. It may be useful for investors, managers and regulators in their decision-making.

Originality/value
This study enriches previous research as IFRS 9 is a new standard, and its adoption consequences need to be investigated. A few recent studies have focused on IFRS 9 as a whole or on other parts of IFRS 9, namely, the impairment regime and hedge accounting and concern developed contexts. However, this research adds to the knowledge of capital market studies by investigating the application of IFRS 9 in terms of classification in the MENA region.

In terms of policy, the difference between China and foreign support in online livestreaming is small, but developed countries have stricter regulations.Originality/valueThe research in this paper has great significance in gaining an in-depth understanding of the development status and trends of China's online livestreaming industry and in designing accurate support policies.
Managing customer-to-customer interactions: revisiting older models for a fresh perspective
Authors: Furrer Olivier , Landry Mikèle , Baillod Chloé 
Published: November 2023

Purpose
This study aims to develop a comprehensive, theoretically grounded framework of customer-to-customer interaction (CCI) management, by revisiting three older services marketing models: the servuction model, the services marketing triangle and the services marketing pyramid.

Design/methodology/approach
Noting the lack of theoretical frameworks of CCI management, this study adopts a problematization approach to identify foundational services marketing models, question their underlying assumptions, develop an alternative conceptual framework and evaluate its adequacy for CCI management, on the basis of a systematic literature review and content analyses.

Findings
By revisiting the assumptions underlying three relevant models in the light of the present-day, technology-infused service environment, this study proposes a four-triangle CCI management framework encompassing four specific modes of CCI management: managerial decisions by the firm; frontline employees; the design of the physical environment; and technology. Furthermore, this study emphasizes the triadic relationships involving the focal customer, other customers and the four modes of CCI management. Building on these findings, this study concludes with an extensive research agenda.

Originality/value
To the best of the authors’ knowledge, this study represents the first scholarly effort in services marketing literature to provide a comprehensive, theoretically grounded framework of CCI management. With its basis in foundational models, the new framework is well-suited to address future challenges to service marketplaces too.
Heat‐evolved algal symbionts enhance bleaching tolerance of adult corals without trade‐off against growth

Published: November 2023

AbstractOcean warming has caused coral mass bleaching and mortality worldwide and the persistence of symbiotic reef‐building corals requires rapid acclimation or adaptation. Experimental evolution of the coral's microalgal symbionts followed by their introduction into coral is one potential method to enhance coral thermotolerance. Heat‐evolved microalgal symbionts of the generalist species, Cladocopium proliferum (strain SS8), were exposed to elevated temperature (31°C) for ~10 years, and were introduced into four genotypes of chemically bleached adult fragments of the scleractinian coral, Galaxea fascicularis. Two of the four coral genotypes acquired SS8. The new symbionts persisted for the 5 months of the experiment and enhanced adult coral thermotolerance, compared with corals that were inoculated with the wild‐type C. proliferum strain. Thermotolerance of SS8‐corals was similar to that of coral fragments from the same colony hosting the homologous symbiont, Durusdinium sp., which is naturally heat tolerant. However, SS8‐coral fragments exhibited faster growth and recovered cell density and photochemical efficiency more quickly following chemical bleaching and inoculation under ambient temperature relative to Durusdinium‐corals. Mass spectrometry imaging suggests that algal pigments involved in photobiology and oxidative stress were the greatest contributors to the thermotolerance differences between coral hosting heat‐evolved versus wild‐type C. proliferum. These pigments may have increased photoprotection in the heat‐evolved symbionts. This is the first laboratory study to show that thermotolerance of adult corals (G. fascicularis) can be enhanced via the uptake of exogenously supplied, heat‐evolved symbionts, without a trade‐off against growth under ambient temperature. Importantly, heat‐evolved C. proliferum remained in the corals in moderate abundance 2 years after first inoculation, suggesting long‐term stability of this novel symbiosis and potential long‐term benefits to coral thermotolerance.
Corrosion mechanism of reactive MgO‐bonded Cr2O3‐bearing castables in CaO–Al2O3–Fe2O3–SiO2‐based steel‐making slag

Published: November 2023

AbstractTo assess the feasibility of the reactive MgO (RM) binder in preparing Cr2O3‐bearing castables, the degradation behavior of RM‐bonded Cr2O3‐bearing castables in CaO–Al2O3–Fe2O3–SiO2‐based steel‐making slag was investigated at 1600°C via refractory cup testing. The corrosion resistance and infiltration resistance of RM‐bonded castables were compared with hydratable alumina (HA)‐bonded and calcium aluminate cement (CAC)‐bonded castables with respect to the differences in phase composition and microstructure. Al2O3 grains in RM‐bonded castable were preferentially attacked by the slag compared with Mg(Al, Cr)2O4 spinel‐based matrix. The formation of spinel‐based and CaO·6Al2O3‐based solid solutions with volume expansion from slag/castable interactions suppressed slag infiltration into RM‐bonded castable matrix. Both experimental observations and thermodynamic calculations indicated that the in situ formed Mg(Al, Cr)2O4 spinel in RM‐bonded castables was the predominant reason leading to the superior slag corrosion resistance and infiltration resistance compared with HA‐bonded and CAC‐bonded Cr2O3‐bearing castables.

Published: November 2023

AbstractAimsTo investigate the trajectory, influencing factors and dynamic relationships between fear of cancer recurrence (FCR) and quality of life (QOL) in lung cancer patients.DesignProspective longitudinal study.MethodsLongitudinal data from 310 lung cancer patients across three hospitals in China were assessed at 1, 3, 6 and 12 months postoperatively (T1–T4). Descriptive statistics characterised patient demographics, clinical characteristics, levels of FCR and QOL. A linear mixed‐effects model was employed to analyse FCR trajectories, identify influencing factors on these trajectories, and predict the impact of FCR on QOL.ResultsFCR changed significantly over time, with a slight decrease during T1–T2, an increase at T3 and gradual decline at T4. Higher fear levels were associated with female sex, suburban or rural residency, being a family breadwinner, presence of comorbidities and negative coping behaviours, and low family resilience. QOL negatively correlated with FCR, and FCR predicted lower QOL.ConclusionsAt 3 and 6 months postoperatively, lung cancer patients, especially women, suburban or rural residents, family breadwinners, those with comorbidities, negative coping behaviours and low family resilience, reported high levels of FCR. Healthcare providers should pay special attention to lung cancer patients especially during the period of 3–6 months post‐surgery and offer tailored interventions to improve their QOL.Implications for the Profession and Patient CareUnderstanding the FCR trajectories, its influencing factors and its negative impacts on QOL can guide the development of targeted interventions to reduce fear and enhance well‐being in patients with cancer.ImpactIdentifying the trajectories and influencing factors of fear of lung cancer recurrence in patients at different time points informs future research on targeted interventions to improve QOL.Reporting MethodThe study adhered to the guidelines outlined in the Statement on Reporting Observational Longitudinal Research.

Published: November 2023

AbstractBackgroundPredicting progression of myxomatous mitral valve disease (MMVD) in dogs can be challenging.Hypothesis/ObjectivesThe mitral regurgitation severity index (MRSI) will predict time to congestive heart failure (CHF) and all‐cause death in dogs with MMVD.AnimalsEight hundred sixty‐nine client‐owned dogs.MethodsRetrospective study pooling data from 4 previous samples including dogs with MMVD stage B2 or C. MRSI was calculated as: (heart rate [HR]/120) × left atrium‐to‐aorta ratio (LA:Ao) × (age in years/10) × 100. Alternative MRSI formulas substituting radiographic measures of left atrial size were also calculated. Cox proportional hazard modeling and time‐dependent receiver‐operator characteristic curves quantified prognostic performance.ResultsFor Stage B2 pooled samples, MRSI > 156 was predictive of time to CHF (median 407 vs 1404 days; area under the curve [AUC] 0.68; hazard ratio 3.02 [95% CI 1.9‐4.9]; P < .001). MRSI > 173 was predictive of all‐cause death (median survival 868 vs 1843 days; AUC 0.64; hazard ratio 4.26 [95% CI 2.4‐7.5]; P < .001). MRSI showed superior predictive value compared to the individual variables of HR, LA:Ao, and age. Variations of the MRSI equation substituting radiographic vertebral left atrial size for LA:Ao were also significantly predictive of outcome in stage B2. MRSI was not consistently predictive of outcome in Stage C.Conclusions and Clinical ImportanceMRSI was predictive of outcome (onset of CHF and all‐cause death) in MMVD Stage B2, demonstrating utility as a useful prognostic tool. Echocardiographic LA:Ao can be effectively replaced by radiographically determined LA size in the MRSI formula.
The “practical mode of teaching” and the state of English studies in the United States
Authors: Denisoff Dennis , Stevens Laura M. 
Published: November 2023

AbstractIn the United States, student eagerness to pursue concentrated study in English literature as well as in other humanities fields has plummeted after the financial crisis of 2008. Envisioned strong career demand and high wages upon graduation are major drivers of program choices, and such demand is articulated through wealthy industries that can also offer funding to universities. That said, it becomes self‐fulfilling to contribute to the cliché of the humanities perpetually being in crisis, which occurs when humanities specialists begin valuing their own fields by the measures celebrated by other programs. Is it possible to take the current situation and leverage our strengths toward constructive innovations in English studies that remain true to our own values? To address this question, we first summarize three key ways in which the situation in the United States is distinct from, yet connected to, that of most other countries: extensive decentralization of education policy and funding; high student debt; and opposition to education in Diversity, Equity, and Inclusion and the humanities in general. After reflecting on the opportunities for greater global connection posed by the pandemic‐driven shift to online learning, we discuss some of our own efforts to build a sense of local and international responsibility in our students. The skills, knowledge, and openness to other cultures and identities that we nurture through the literature we teach and the socially invested pedagogy we practice allow us to incorporate ethics and empathy into the design of international economics and to help ensure that a sense of local and global responsibility is part of its operation.

AbstractBackgroundPermanent pacemaker (PPM) implantation is a well‐established treatment for symptomatic sinus node dysfunction (SND). The optimal timing of this intervention is unclear, with atrioventricular blocks often prioritized in resource stressed waiting lists due to mortality concerns.MethodsMortality data was compared between patients receiving elective outpatient (OP) PPM implantation, and those presenting to hospital for urgent inpatient (IP) management for symptomatic SND. Survival analysis was conducted using Kaplan‐Meier plots and compared using the log‐rank test. Univariable and multivariable Cox regression, as well as propensity score matching analyses were performed to assess the prognostic effect on 30‐day and 1‐year all‐cause mortality of inpatient implant.ResultsOf the 1269 patients identified with isolated SND, 740 (58%) had PPMs implanted on an OP and 529 (42%) on an IP basis. Mortality was significantly worse in patients where management was driven by hospital admission on an urgent basis (Log‐Rank χ2 = 21.6, p < 0.001) and remained an independent predictor of 1‐year all‐cause mortality (HR 3.40, 95% CI 1.97–5.86, p < 0.001) on multivariable analysis.ConclusionsSND is predominantly a disease associated with ageing and comorbid populations, where avoidance of deconditioning, hospitalization acquired infections, and polypharmacy is advantageous. Admission avoidance is therefore the preferable strategy.
