Wheel wear of mountain metro vehicles with complex line conditions
Authors: Qi Yayun , Ao Peng , Hou Maorui , Zhang Ailong 
Published: October 2024

Purpose
Mountain metro vehicles have unique wheel wear characteristics due to the complex flat and longitudinal lines. With a combination of flat and longitudinal curved tracks, the traction and braking conditions are more frequent in mountain metro vehicles. This paper aims to analyze the wheel wear characteristics of mountain metro vehicles in complex flat and longitudinal lines.

Design/methodology/approach
A dynamic model of the mountain metro vehicle and a wear model are established to analyze the dynamic and wheel wear characteristics of mountain metro vehicles. The wheel wear law of mountain metro vehicles under complex track conditions is analyzed, and the suppression measure based on variable stiffness rotary arm nodes of mountain metro vehicles is proposed.

Findings
The results showed that the maximum wheel wear depth without considering the ramp track and considering the ramp track are 3.283 mm and 3.717 mm, respectively; the maximum wheel wear depth increases by 13.2%. Wheel wear can be effectively suppressed by the variable stiffness rotary arm model, and the maximum wear depth of the wheel profile is 3.316 mm, which is reduced by 10.79% compared with the constant stiffness model.

Originality/value
A dynamic model of a mountain metro vehicle is established, and the metro vehicle wheel wear under the large ramps under the traction and braking conditions is analyzed, and the metro vehicle wheel wear suppression measure based on variable stiffness rotary arm nodes is proposed.

Personal enactment as an antidote to depressed mood’s effect on nurses’ work passion
Authors: Rahaman H.M. Saidur , Babalola Mayowa T. , Khan Abdul Karim , Hochwarter Wayne A. 
Published: October 2024

PurposeBecause of the nature of nurses’ daily jobs, their work passion is critical for their quality performance and well-being. However, more research must examine the antecedents of nurses' work passion. Against this backdrop, in the present study, we draw on the conservation of resources (COR) theory to hypothesize that the negative relationship between nurses’ depressed mood at work and work passion is moderated by their enactment such that a relatively high level of personal enactment weakens the negative effect of depressed mood at work on their work passion.Design/methodology/approachWe examine our hypothesis using a three-wave time-lagged design involving 147 nurses (RN or LPN) working at a medium-sized healthcare facility in the rural Southern USA.FindingsResults support our hypothesis that nurses’ personal enactment moderates the relationship between their depressed mood at work and work passion.Research limitations/implicationsNurses' depressed mood at work can be less harmful to their work passion, particularly when they demonstrate a relatively higher level of personal enactment.Originality/valueThis study demonstrates that personal enactment attenuates the adverse effects of depressed mood at work when nurses possess elevated work passion levels.
Casually cynical or trapped? Exploring gig workers’ reactions to psychological contract violation

Published: October 2024

PurposeDrawing on psychological contract (PC) theory and platform labor research, the purpose of our study was to explore gig workers’ reactions to perceived PC violation. Our study was set against the backdrop of the COVID-19 pandemic, which brought workplace health and safety issues into much sharper focus, even in nonstandard employment arrangements like gig work.Design/methodology/approachThis study employed a mixed-methods design. In Study 1, we tested a conceptual model of US-based ride-hail drivers’ (n = 202) affective and cognitive reactions to Uber’s (lack of) commitment to safe working conditions. In Study 2, we conducted interviews with 32 platform workers to further explore an unexpected finding from Study 1.FindingsIn Study 1, we found that drivers’ perceptions of PC violation were related to decreased trust in Uber and higher intentions to leave this line of work; however, cynicism toward Uber only predicted withdrawal intentions for those drivers who did not believe that they had job alternatives available outside of gig work. We explored this further in Study 2, where we found that workers with low economic dependence on gig work could afford to be casually cynical toward the platform, while high-dependence workers felt “trapped” in this line of work.Originality/valueWe contribute to the social/relational theoretical approach to gig work more broadly and to the literature on PC in platform work more specifically. We also add to the emerging literature on how economic dependence shapes workers’ experience of platform work. Our findings around low-dependence gig workers experiencing a more indifferent form of cynicism – which we have termed casual cynicism – highlight the importance of treating the context of gig work as unique, not merely an extension of traditional management research.
Perceptions and contradictions: a study of market orientation and innovation among Cuban entrepreneurs
Authors: Gómez García Luis Demetrio , Hernández Ruíz Alma Delia 
Published: October 2024

Purpose
This study aims to examine whether market orientation or innovation is a more significant mediator between an entrepreneur’s culture and perceived success in Cuba, where innovation is highly regarded because of economic challenges and US embargoes, but doubts persist about market orientation because of its socialist economy.

Design/methodology/approach
Havana entrepreneurs were surveyed on culture, market orientation and innovation. Data were analyzed using structural equation modeling with the partial least squares approach in SmartPLS 4.

Findings
The results showed partial mediation for both market orientation and innovation. Culture significantly affects performance directly. Surprisingly, a less market-oriented culture enhances performance, with innovation acting as the stronger mediator, despite the inverse relationship between market orientation and innovation.

Research limitations/implications
The limitations include reliance on self-reported measures, lack of objective performance verification and a narrow focus on entrepreneurs rather than clients. Despite these constraints, the study provides valuable exploratory insights into Cuba’s closed economy, following the principle of being “approximately right than exactly wrong.”

Practical implications
The findings confirm the positive impact of Cubans’ innovative spirit on performance but reveal a contradiction: less market-oriented cultures perceive themselves as market-oriented and perform better. This misperception suggests the need for further investigation and training to promote market-oriented business culture. Collaboration with international business schools may be necessary, as this distortion could harm customer satisfaction.

Originality/value
The originality of the research lies in that, to the best of the authors’ knowledge, this is the first study on Cuban entrepreneurs’ market orientation. It has the value to illustrate how socialists’ ideology can contradict assumed theoretical established approaches about market functioning.
Service before self: exploring resilience and locus of control in the frontline service effort behavior
Authors: Shagirbasha Shameem , Madhan Kumar , Iqbal Juman , Khan Hamia 
Published: October 2024

PurposeDrawing on the conservation of resource (COR) theory, this study examines the direct relationships between customer incivility and service effort behavior with psychological resilience mediating this association. Furthermore, the study also explores the moderated-mediation effect of internal locus of control.Design/methodology/approachTwo studies were carried out, employing a time-lagged approach. In study 1, data were collected from 422 frontline service employees in the hospitality sector. This was followed by Study 2 in which data were collected from 530 frontline service employees in banking and retail industries. The data were analyzed using SPSS PROCESS macros and AMOS.FindingsThe results specified that customer incivility negatively influences service effort behavior among frontline service employees. Moreover, it was also found that psychological resilience mediated the negative association between customer incivility and service effort behavior. Finally, the results show that the moderated-mediation effect of internal locus of control was also supported.Originality/valueThe study is an attempt to broaden the frontier of customer incivility and highlight how it affects service effort behavior. The findings also highlight the mediating role of psychological resilience between customer incivility and service effort behavior. Moreover, this study makes an enriching contribution by exploring the moderating role of internal locus of control. To the best of our knowledge, such associations remain outside the purview of previous examinations.
Corporate tax avoidance and narrative disclosure tone: a developing country perspective
Authors: Hasan Arshad , Anwar Waqas , Zhang Joseph H. , Marques Ana 
Published: October 2024

Purpose
This study aims to examine the link between tax avoidance, corporate governance and narrative disclosure tone using a sample of public companies in Pakistan.

Design/methodology/approach
Data for 125 companies listed on the Pakistan Stock Exchange (PSX) are collected over 10 years from 2011 to 2020. Sentiment analysis is conducted to determine the disclosure tone, and regression analysis is used to test the association between the variables.

Findings
This paper finds that firms that engage in tax avoidance tend to use a more positive disclosure tone and are more likely to engage in impression management. Moreover, promoting sound governance through board independence and gender diversity is associated with a less positive disclosure tone. However, firms with more family board members and higher foreign ownership are more likely to use a more positive disclosure tone.

Practical implications
Regulators can use this information to develop better guidelines to protect investors and ensure faithful disclosures to address both positive and negative news.

Originality/value
The study contributes to the literature by examining corporate tax avoidance as a determinant of narrative disclosure tone, a relationship that has not been widely explored. Moreover, as most disclosure tone research has been conducted in developed countries, this paper provides valuable evidence from a developing country.
A macroecological analysis of ecological uniqueness of freshwater macrophyte assemblages across Europe and North America

Abstract

Understanding spatial variation of species composition at different scales is essential for efficient conservation planning. Here, we investigate ecological uniqueness patterns of freshwater macrophyte assemblages at continental extents.

We explored the similarities and differences in the patterns of ecological uniqueness between Europe and North America in relation to species richness and environmental variables using macrophyte presence–absence data in 50 × 50 km grid cells. To describe the ecological uniqueness of macrophyte assemblages, we used an index called ‘local contribution to beta diversity’ (LCBD).

First, we used linear regression to evaluate the relationship between ecological uniqueness and species richness. Second, the variation of ecological uniqueness was modelled using environmental variables in generalized additive modelling (GAM). Third, boosted regression tree (BRT) analysis was performed with the same environmental variables to compare BRT results with the results from GAM.

The results revealed relatively similar patterns of ecological uniqueness in both continents. The relationship between species richness and ecological uniqueness was overall negative but showed differences in the form and degree of the relationship between Europe and North America. The main driver of ecological uniqueness in both continents was mean annual temperature, with further effects associated with annual precipitation, elevation range, alkalinity and the proportion of freshwaters in a grid cell.

Synthesis. Our results showed that species richness and ecological uniqueness may be negatively correlated at large spatial extents, and that the form of the relationship is likely to depend on the species richness profile of the area. The significant influence of climate on the ecological uniqueness of macrophyte assemblages suggests that changes in climate and land use may shape unique macrophyte assemblages. Thus, conservation strategies should consider protection measures, especially in the northern areas with unique macrophyte species assemblages, as they are expected to face many changes in the future. Identifying areas with high ecological uniqueness at different scales is important for efficient implementation of biodiversity conservation practices.
Decomposing the impact of genetically modified organism regulation on bilateral trade: An application to corn trade
Authors: Hedoui M. Amine , Beghin John C. 
Published: October 2024

AbstractOur study investigates the impact of genetically modified organism (GMO) regulations on international agricultural trade, with a specific focus on GMO approvals. We analyse the effects of GMO regulations on bilateral trade through three main pathways: productivity enhancements in the exporting country, regulatory dissimilarities between trading partners and the influence of GMO approvals on demand in the importing country. Using a panel data set on corn trade and employing advanced econometric techniques, our findings reveal that GMO cultivation approvals in exporting countries have the most substantial and consistent positive effect on trade. Conversely, the impact of GMO demand approvals in importing countries is relatively smaller and negative. Additionally, regulatory dissimilarities between any two countries become negligible when accounting for the effects of cultivation and demand approvals. Thus, GMO approval regulations exert more significant multilateral effects on trade than bilateral ones.

Published: October 2024

ABSTRACTBackgroundNinety‐eight percent of neonatal deaths worldwide occur in low‐ and middle‐income countries (LMICs), yet there is little bereavement care guidance available for these settings.ObjectivesTo explore parents', families' and healthcare professionals' experiences of care after neonatal death in healthcare facilities in LMICs.Search Strategy and Selection CriteriaFour databases were searched for peer‐reviewed literature, meeting the inclusion criteria of qualitative studies exploring the experiences of people who provided or received bereavement care following neonatal death in a LMIC healthcare setting.Data Collection and AnalysisData were collected by two independent reviewers, collated through line‐by‐line coding and then reciprocal and refutational translation, and analysed through Noblit and Hare's seven‐step meta‐ethnography approach to create first‐, second‐ and third‐order themes.Main ResultsSeven first‐order themes extracted from the literature included emotional responses, social relationships, staff and systems, religion, connecting with the baby, coping strategies and economic concerns. From these data, three third‐order themes arose: The individual, the healthcare setting and the community/context.ConclusionsOverarching themes in bereavement care shape grief responses and are often similar across geographical locations. Analysing these similarities allows a deeper understanding of the important elements of bereavement care and may be helpful to inform the creation of high‐quality, bereavement care guidelines suitable for use in LMIC settings.

AbstractObjectivesTo identify the influence of a Disability Liaison Officer (DLO) service in the ED setting on people with disability (PWD). For this project, PWD included adults with communication disability, intellectual disability or autism spectrum disorder.MethodsThis was a single‐centre retrospective cohort study, at an adult major referral ED in Melbourne, Australia. Patients were eligible for inclusion if they were ≥18 years of age, presented to the ED between 1 April 2022 and 30 April 2023, and had a disability alert in their electronic medical record. Eligible patients were divided into two cohorts: (i) patients managed using standard ED care and (ii) patients managed using DLO model. ED length of stay (LOS) was the main outcome measure.ResultsAfter adjusting for baseline differences in age, initial GCS and disability type, the DLO service was associated with earlier disposition from the ED (adjusted hazard ratio [aHR] 1.44; 95% confidence interval [CI]: 1.23–1.69; P < 0.001). For the subgroup of patients discharged directly from the ED, the association of DLO service and earlier disposition remained statistically significant (aHR 2.47; 95% CI: 1.83–3.33; P < 0.001). Among patients admitted to the emergency short stay unit (aHR 1.67; 95% CI: 0.99–2.80; P = 0.06), and those admitted to inpatient wards (aHR 0.89; 95% CI: 0.65–1.23; P = 0.50), there was no significant association of the DLO service with time to disposition.ConclusionsThe DLO service was associated with a reduction in ED LOS for PWD. Further assessment of the service using patient‐ and carer‐reported outcome measures and cost‐effectiveness studies are indicated.

AbstractThe integrated behaviour of multiple senescent cell types within a single human tissue leading to the development of malignancy is unclear. Patients with Familial Melanoma Syndrome (FMS) have heterozygous germline defects in the CDKN2A gene coding for the cyclin inhibitor p16INK4a. Melanocytes within skin biopsies from FMS patients express significantly less p16INK4a but express higher levels of the DNA‐damage protein 𝛾H2AX a than fibroblastic cells. However, patient fibroblasts also exhibit defects since senescent cells do not increase in the skin during ageing and fibroblasts isolated from the skin of patients have increased replicative capacity compared to control fibroblasts in vitro, culminating in abnormal nuclear morphology. Patient derived fibroblasts also secreted less SASP than control cells. Predisposition of FMS patients to melanoma may therefore result from integrated dysregulation of senescence in multiple cell types in vivo. The inherently greater levels of DNA damage and the overdependence of melanocytes on p16 for cell cycle inhibition after DNA damage makes them exquisitely susceptible to malignant transformation. This may be accentuated by senescence‐related defects in fibroblasts, in particular reduced SASP secretion that hinders recruitment of T cells in the steady state and thus reduces cutaneous immunosurveillance in vivo.

ABSTRACTProblemPreterm birth (PTB) is a significant cause of maternal and neonatal morbidity and mortality worldwide. However, the effectiveness of progesterone (P4) which is clinically used for PTB management remains controversial and necessitates research into new therapeutic optionsMethod of StudyIn the current study, we investigated the effectiveness of two chlorophyll derivatives, pheophorbide a (PBa) and pheophytin a (PTa), in counteracting PTB. Timed‐pregnant mice (gestation day 17 ± 0.5) received lipopolysaccharide (LPS) (25 µg/mouse) or phosphate‐buffered saline (PBS) intraperitoneally, with PBa, PTa, progesterone (P4), and co‐administration of P4 and ibuprofen (IBP), administered orally 2 h prior.ResultsThe LPS group experienced PTB and 100% fetal mortality, whereas the PBa and PTa groups showed a delayed onset of LPS‐induced PTB, with significantly decreased PTB rate and fetal mortality. In addition, PBa and PTa suppressed LPS‐induced pro‐inflammatory cytokines and NF‐κB transcription factor while increasing anti‐inflammatory cytokines in the placenta and uterus.ConclusionsOur findings indicate that the chlorophyll derivatives, PBa and PTa increase fetal survival in infection‐induced PTB and demonstrate greater efficacy than P4 in preventing PTB.

ABSTRACTProblemTo identify the predictive factors for the recurrence of chronic endometritis (CE) in infertile women.Method of studyIn this case‐control study, 1170 infertile women recovered from CE and underwent fertility treatment between December 2018 and August 2021. Among the 146 women (12.5%) who did not conceive or experienced pregnancy loss in 18 months after CE recovery, 105 consecutive women who underwent repeat endometrial biopsy for CD138 immunostaining and endometrial bacterial culturing were recruited. Thereafter, patients with and without CE recurrence were compared.ResultsThe total recurrence rate of CE was 29.5% (31 women). Multivariable logistic regression analysis to determine predictive factors for CE recurrence revealed that hysteroscopic surgery (odds ratio [OR], 0.10; 95% confidence interval [CI], 0.02–0.56; p = 0.0009) and pregnancy loss (OR, 4.13; 95% CI, 1.31–13.05; p = 0.016) were significantly associated with decreased and increased CE recurrence rates, respectively. Also, reexamination with CD138 immunostaining after 16–18 months (OR, 9.75; 95% CI, 1.47–64.64; p = 0.024) was significantly associated with increased CE recurrence rates. Among 49 patients without a history of pregnancy loss, the cumulative CE recurrence rates after 6, 12, and 18 months were 5.6%, 13.5%, and 20.4%, respectively.ConclusionsWe recommend reexamination with endometrial CD138 immunostaining in patients with pregnancy loss or long‐term infertility during fertility treatment. Hysteroscopic surgery without antibiotic therapy for CE associated with intrauterine abnormalities is also recommended.
